FIELD OF THE INVENTION
[0002] This application relates generally to vaporization of phyto
materials, and more specifically to devices for vaporizing phyto
materials.
INTRODUCTION
[0003] The following is intended to introduce the reader to the
detailed description that follows and not to define or limit the
claimed subject matter.
[0004] Aromatherapy generally uses plant matter, phyto materials,
and essential oils, phyto material extracts, for therapeutic
benefits. Essential oils can be extracted from phyto materials,
such as the leaves of plants. In some cases, essential oils may be
massaged into the skin to provide therapeutic benefits. In other
cases, essential oils may be ingested or inhaled for therapeutic
purposes.
[0005] In some cases, phyto materials may be heated in order to
release the essential oils or aerosols therefrom. By heating phyto
materials at predetermined temperatures, essential oils and
extracts can be boiled off. Depending on the temperature at which
the phyto materials are heated, an aroma or vapor may be given off.
This vapor may be inhaled by a user for its
[0006] therapeutic benefits.
[0007] Various methods of vaporizing phyto materials are known.
Devices that vaporize phyto materials are generally known as
vaporizers and may heat through conduction, direct contact with
phyto material, or may heat through convection, hot air or
combinations of both.

[0066] Embodiments described herein relate generally to
vaporization of vaporizable material, such as phyto materials and
phyto material products. Although embodiments are described herein
in relation to vaporization of phyto material and phyto material
products, it will be understood that other vaporizable materials,
such as vaporizable nicotine products and/or synthesized
vaporizable compounds, or combinations of vaporizable components
may be used. For instance, various vaporizable products containing
nicotine or plant derived extracts or oils, such as cannabis
extract, CBD or terpene extracts and/or synthesized compounds may
be used. Phyto material products may be derived from phyto
materials such as the leaves or buds of cannabis plants.
[0067] Various methods of vaporizing phyto materials and phyto
material products, such as cannabis products, are known. Phyto
material is often vaporized by heating the phyto material to a
predetermined vaporization temperature. The emitted phyto material
vapor can then be inhaled by a user for therapeutic purposes.
[0068] Devices that vaporize phyto materials are generally known as
vaporizers. In some cases, oils or extracts derived or extracted
from the phyto materials may also be vaporized. For cannabis oils
or extracts, temperatures in the range of about 500 to 700 degrees
Fahrenheit may be applied to vaporize these phyto material products
can generate phyto material vapor.
[0069] The phyto material vapor may be emitted at a temperature
that is uncomfortable for a user to inhale. Accordingly, it may be
desirable to cool the vapor prior to inhalation.
[0070] Referring to FIGS. 1A and 1B, a dual chamber vaporization
device DCVD 100 in accordance with a first embodiment of the
invention is shown and may include a device body 102 and a
mouthpiece lid 104 may be moveably mounted to device body 102
(hinged or friction fit or slid on). Referring to FIGS. 1C and 1D,
the DCVD 200 in accordance with a second embodiment of the
invention may include a device body 102 and a selective mouthpiece
lid 104s may be moveably mounted to device body 102 (hinged or
friction fit or slid on).
[0071] The mouthpiece lid 104 or selective mouthpiece lid 104 may
be movably mounted to the device body 102 by a friction fit
connection (FIG. 1A), such as a snap fit connection formed by a
tongue 104t and a groove 104g that mates to form a frictional fit
connection). In other embodiments, the mouthpiece lid 104 may be
movably mounted to the device body 102 by a hinged connection, or a
slide-in groove connection (not shown) or a magnetic connection.
For example, the mouthpiece lid 104 may be snapped on and off the
body device 102 via the tongue 104t and groove 104g on the body
device 102. For example, the body may have a lip around an outer
edge. The mouthpiece lid 104 may be sized to fit within the lip and
may be held in place by friction along the lip's edge. The
mouthpiece lid 104 may contain an indent 104i or a tab to enable
the user to remove the lid 104. A plurality of tongue and groove
assemblies may be disposed for coupling of the mouthpiece 104, 104s
with the de vice body 102. An elastomeric material seal may be
provided as part of the mouthpiece lid 104 or selective mouthpiece
lid 104 to provide for an approximately air tight seal for sealing
of the mouthpiece lid 104 or selective mouthpiece lid 104 when
engaged with the device body 102 in the first or second
orientation. When a vacuum is created from the inhalation aperture
130 by the user, the elastomeric material seal facilitates of vapor
transfer from the first and second heating chambers, 106 and 206,
into the air-cooling assembly 124 or air missing assembly or air
and vapor mixing assembly.

heating element assembly is shown in FIG. 2A.
[0074] Preferably the second heating chamber 206 and the second
heating element assembly 212 is may be for operating at a higher
temperature than the first heating element assembly 112. The first
heating chamber 106 may be for use with ground phyto material and
the second heating chamber 206 may be for use with phyto material
extract. Optionally the first and second heating chambers are for a
same type of phyto material, where both are for use with phyto
material extract or both are for use with leaf phyto material.
[0075] Referring to FIG. 1E and FIG. 1N, the DCVD 100 and the DCVD
200 may include an energy storage module 116 such as a battery
electrically coupled to the first heating element assembly 112 and
to the second heating element assembly, 212. Energy storage module
116 may be used to energize the first heating element assembly 112
to heat the phyto material 419 within the first chamber cavity 120
through a conduction heating process and to energize the second
heating element assembly 212 to heat the phyto material extract 421
within the second chamber cavity 220 using a conduction heating
process.
[0076] The DCVD 100 and the DCVD 200 may include a control circuit
114 electrically coupled to the first heating element assembly 112
and the second heating element assembly 212 and energy storage
module 116. The control circuit 114 may control the operation of
the heating element assembly 112 and 212. The control circuit 114
may be used to activate/deactivate the heating element assembly 112
and 212 or to apply a pulse width modulated (PWM) signal to at
least one of the heating element assemblies 112 and 212.
[0077] The control circuit 114 may also be used to adjust the
settings of the DCVD 100 and DCVD 200, such as a first and second
predetermined vaporization temperature. The control circuit 114 may
control the flow of current through the heating element assembly
112 and 212 in accordance with a selected first and second
predetermined vaporization temperature. For example the control
circuit is used to set the first predetermined temperature using a
temperature sensor or a PWM signal of to set the temperature within
approximately about 350 Fahrenheit and 450 Fahrenheit and to set
the second predetermined temperature to within approximately 450
Fahrenheit and 750 Fahrenheit.
[0078] As is shown in FIG. 1G and FIG. 1E, the control circuit 114
may also manage the operation of other components of DCVD 100 and
DCVD 200 such as user input controls 997, such as buttons, such as
a temperature up button 997a and a temperature down button 997b and
a second heater button 997c to control power applied to the. Second
heating element assembly 212.
[0079] Energy storage module 116 may be a rechargeable energy
storage module, such as a battery or lithium battery or super
capacitor. DCVD 100 and 200 may include a power supply port 199
(e.g. a USB-port or magnetic charging port) that allows the energy
storage module 116 to be recharged. The energy storage module 116
may optionally be removable to allow it to be replaced through a
battery removal port 912 or removable cap, as is shown in FIG. 1N.
For instance, DCVD 100 may include one or more output components
299 (such as an LED display) that provide visual or audible signals
to a user regarding the configuration and settings of DCVD 100. In
some cases, DCVD 100 may include wireless communication modules 999
to allow the DCVD 100 to communicate with another wireless device
such as a smartphone 998 or tablet. Referring to FIG. 1M, the a
stir and load tool 171 is provided as a removable part of the DCVD

[0080] Referring to FIG. 1E, the first heating chamber 106 may
include a first end 106a, a second end 106b. The first heating
chamber 106 may also include one or more first chamber sidewalls
106s extending from the first end to the second end 106b with a
first chamber third sidewall 108c capping the first heating chamber
106 proximate the second end 106b. The first chamber sidewalls 106s
together with the first chamber third sidewall 108c may define a
first chamber cavity 120 of the first heating chamber 106. Ground
leaf phyto material may be loaded to the first chamber cavity 120
in preparation for vaporization. Referring to FIGS. 1A, 1B and 1E,
the first heating chamber 106 may be cylindrical. The first heating
chamber 106 includes a cylindrical sidewall 108a extending from the
first end 106a to the second end 106b. The first heating chamber
106 may also include a first chamber third sidewall 108c capping
the cylindrical heating chamber at the second end 106b that may
also be referred to as a base or floor. This may allow air to flow
into the first chamber cavity 120 of first heating chamber 106.
First heating chamber 106 may also have an open upper end or side
106d proximate the first end 106a. The first chamber cavity 120
generally defines a volume within which a user may add ground leaf
phyto material. For example, a user may add loose leaf phyto
material 419 within the chamber cavity through the open upper end
or side 106d proximate the first end 106a.
[0081] Referring to FIGS. 1A, 1B and 1E, the second heating chamber
206 may include a first end 206a, a second end 206b. The second
heating chamber 206 may also include one or more second chamber
sidewalls 206s extending from the first end to the second end 206b
with a second chamber third sidewall 208c capping the second
heating chamber 206 proximate the second end 206b. The second
chamber sidewalls 206s together with the second chamber third
sidewall 208c may define a second chamber cavity 220 of the second
heating chamber 206. Where the second chamber third sidewall 208c
may also be referred to as a base or floor. The second heating
chamber 206 may be cylindrical and may be parallel with the first

[0082] FIGS. 1A, through 1D and FIG. 1L illustrates a separator rib
156 formed between the first heating chamber 106 first end 106a and
the first end 206a of the second heating chamber 206 where the
separator rib 156 may be for creating a raised protrusion between
the first and second cavities, 120 and 220. This separator rib 156
may assist a user in loading of phyto material into either one of
the chambers so that for example the loose leaf phyto material does
be dispensed into second cavity 220. The separator rib 156 may also
protrude into a separator rib cavity 157 (FIG. 1H, 1E) formed in
the mouthpiece lid so that material from one chamber may have less
of a likelihood of flow between chambers when the DCVD 100 and DCVD
200 is inverted.
[0083] The mouthpiece lid 104 may be moved between an open position
(shown in FIGS. 1A, 1B) and a closed position (FIG. 1G, 1H, 1E, 1K)
showing the selective mouthpiece lid 104s). In the open position,
the upper end of the first chamber cavity 120 may be exposed. This
may allow a user to load phyto material 419 into the first heating
chamber 106 and phyto material extract 421 into the second heating
chamber 206 for vaporization and/or dispose of vaporized phyto
material therefrom. The mouthpiece lid 104 may also be rotated
about a vertical axis/central axis 512 where the mouthpiece portion
proximate the first and second cavities, 120 and 220 may have a
symmetry and may snap or frictionally engage with the body 102 in
either one of two orientations. FIG. 1A shows a first orientation
and FIG. 1B shows a second orientation.
[0084] Referring to FIG. 1A, in the first orientation the
mouthpiece lid 104 may include a first perforated floor section
120p to be aligned with the first end 106a of the first heating
chamber 106 and a second perforated floor section 220p may be
aligned with the first end 206a of the second heating chamber 206.
Referring to FIG. 1B, in the second orientation the mouthpiece lid
104 may include the first perforated floor section 220p to be
aligned with the first end 106a of the first heating chamber 106
and a first perforated floor section 120p may be aligned with the
first end 206a of the second heating chamber 206. When the
mouthpiece lid 104 is moved to the closed position and in the first
orientation, the mouthpiece lid 104 and the first heating chamber
106 and the second heating chamber 206 may enclose the first and
second chamber cavities 120, 220. When the mouthpiece lid 104 is
moved to the closed position and in the second orientation, the
mouthpiece lid 104 and the first heating chamber 106 and the second
heating chamber 206 may enclose the first and second chamber
cavities 120, 220.
[0085] Referring to an exploded view of the mouthpiece lid as shown
in FIG. 1K and FIG. 1o and FIG. 1i, the mouthpiece lid 104 may also
include a lid floor 104f having a perforated floor section 104p
with an inner lid space 122 defined between the outer wall 104w and
the lid floor 104f with an inhalation aperture defined 130 in the
outer wall 104w, the inhalation aperture 130 fluidly coupled to the
inner lid space 122 and downstream from the lid floor 104f. In the
closed position, the lid 104 and the first and second heating
chambers, 106 and 206 enclose the first and second chamber
cavities, and at least a portion of the perforated floor section
104p overlies the first and second chamber cavities 120, 220
proximate the first ends 106a and 206a, whereby the first and
second chamber cavities 120, 220 and the inner lid space 122 are
fluidly connected. In the closed position, at least one of the
first and second heating element assemblies 112 and 212 are
energizable to heat phyto material disposed within the chamber
cavities to a predetermined first and second vaporization
temperatures for creating a first vapor and a second vapor; and to
define a vapor flow path from the first and second chamber cavities
through the perforated floor 104f to the inner lid space and the
inhalation aperture for the first vapor and second vapor to
propagate through the inhalation aperture 130.
[0086] Referring to FIGS. 1i and 1o, the first perforated floor
section 120p of mouthpiece lid 104 may also include apertures or
first pores 134 throughout its surface and the second perforated
floor section 220p of mouthpiece lid 104 may also includes
apertures or second pores 135 throughout its surface. When in the
first orientation and when the mouthpiece 104 is in the closed
position the pores 134 may permit first vapor to pass from the
first chamber cavity 120 to the inner lid space 122 through the
first perforated floor section 120p and for second vapor to pass
from the second chamber cavity 220 to the inner lid space 122
through the second perforated floor section 220p. When in the
second orientation and when the mouthpiece 104 is in the closed
position the pores 134 may permit a second vapor to pass from the
second chamber cavity 220 to an inner lid space 122 through the
first perforated floor section 120p and for first vapor to pass
from the first chamber cavity 120 to the inner lid space 122
through the second perforated floor section 220p.
[0087] The size of first and second pores 134, 135 may be selected
to inhibit non-vaporized pieces or flakes of the phyto material
from passing into the air cooling assembly 124 and out the
inhalation aperture 130 into the user's mouth. Thus, the pores 134
may also provide a filtering action. The pores 134, 135 in
conjunction with the air cooling assembly 124 may also provide a
filtering action through a shape of the air cooling assembly 124
that uses a curved air path or non linear air path. In some
embodiments a first air cooling path length formed between the
first perforated floor section 120p and the inhalation aperture 130
may be shorter than a second air cooling path length formed between
the second perforated floor section 220p and the inhalation
aperture 130. As such the user may be able to adjust between the
first orientation of the mouthpiece lid 104 and the second
orientation of the mouthpiece lid 104 in order to select from which
cavity additional vapor cooling is preferred. The first air cooling
path length may provide for a reduced amount of vapor cooling as
compared with the second air cooling path length.
[0088] An additional air cooling assembly may comprise a porous
mesh that may be inserted proximate the mouthpiece for receiving of
the vapors emitted from either of the chambers for providing of
additional vapor cooling to at least one of the first air cooling
path length and second air cooling path length. The size of pores
134. 135 may depend on the form of the phyto material being used.
In some embodiments, the pores 134, 135 may be between 0.1 and 0.6
mm. For example, the pores 134, 135 may be between 0.025 and 0.3
mm. In some embodiments, the pores 134 may be between 0.05 and 0.2
mm. In some embodiments the first perforated floor section 120p and
the second perforated floor section 220p may have pores of varying
sizes. The size of pores 134, 135 may be selected to inhibit
non-vaporized pieces or flakes of the phyto material from passing
into the air cooling assembly 124 and out the inhalation aperture
130 into the user's mouth. Thus, the pores 134, 135 may also
provide a filtering action. The pores 134 in conjunction with the
air cooling assembly 124 may also provide a filtering action
through a shape of the air cooling assembly 124 that uses a curved
air path or a tortuous air path.
[0089] First vapor from the first chamber cavity 120 may enter the
air inlet of the air cooling assembly 124 at a first temperature T1
and exit through the mouthpiece 130 at a second temperature T2 that
is lower than the first temperature T1. This may provide a user
with a more comfortable, and safer, temperature of vapor for
inhalation. Second vapor from the second chamber cavity 220 may
enter the air cooling assembly 124 at a third temperature T3 and
exit through the mouthpiece 130 at a fourth temperature T4 that is
lower than the third temperature T3. This may provide a user with a
more comfortable, and safer, temperature of at least one of first
and second vapor for inhalation.
[0090] In the open position (shown in FIGS. 1A to 1D), the chamber
cavities 120, 22 are open to the external environment 144 and the
phyto material 419, 421 may be loaded into the first chamber cavity
120 and the second chamber cavity 220 of the first heating chamber
106. As discussed above, loose leaf phyto material 419 may be
distributed within the first chamber cavity 120 and phyto material
extract is placed in proximity of the second heating element
assembly.
[0091] In the closed position the mouthpiece lid 104 (FIG. 1A, 1B)
or the selective mouthpiece lid 104s (FIG. 1C, 1D) and device body
102 may enclose the first chamber cavity 120 and the second chamber
cavity 220. In the closed position, at least a portion of the
perforated floor 120p covers the first chamber cavity 120 and at
least a portion of the second perforated floor 220p covers the
second chamber cavity 220. In this position, the first chamber
cavity 120, 220 and the inner lid space 122 are in fluid
communication via the pores 134, 135 and the first and second
perforated floor 120p, 220p.
[0092] Further, when in the closed position, the heating element
assemblies 112, 212 may be selectively energized to heat the phyto
material 419 in the first chamber cavity 120 to the first
predetermined temperature to vaporize the phyto material 419 and
selectively heat the heat the phyto material 421 in the second
chamber cavity 220 to a second predetermined temperature to
vaporize the phyto material extract 421.
[0093] When the user inhales from the inhalation aperture 104,
ambient air 125 may be drawn from the external environment 555 into
the first chamber cavity 120 through the first chamber third
sidewall 108c via the first chamber pores 106p in fluid
communication with the air intake manifold 191. While in the first
chamber cavity 120, ambient air is mixed with the vaporized phyto
material and is the first vapor drawn by the inhalation through the
air cooling assembly and out the inhalation aperture 130 and
ambient air 555 may be drawn from the external environment 144 in
fluid communication with the air intake manifold 191 into the
second chamber cavity 220 through the second chamber third sidewall
208c via the second chamber pores 206p. While in the second chamber
cavity 220, ambient air is mixed with the vaporized phyto material
extract and is the second vapor then drawn by the inhalation
through the air cooling assembly and out the inhalation aperture
130.
[0094] Referring to FIGS. 1K and 1G and 1H, where FIG. 1H shows a
cutaway side view of the selective mouthpiece lid 104s and the
heating unit and FIG. 1H shows the selective mouthpiece coupled
with the device body and FIG. 1K shows an exploded proportional
view of the selective mouthpiece lid. A selective mouthpiece lid
104s in an exploded view where a selector switch 181 is shown as
well as a selector slider valve 182, the selector slide valve for
selectively closing second pores 135, when the second pores 135 are
selectively closed then inhalation from the inhalation aperture
through the second perforated floor section 220p is substantially
blocked. The selector switch 181 protrudes past the selective
mouthpiece lid 104s so that it allows for easy actuation by the
user. In some embodiments (FIG. 1J) the selector switch 181 is only
operated when it is depressed by the end user (second pores 135 are
selectively closed during applied pressure and working against a
spring force or a material deforming force) and when released
second pores 135 are selectively open. In some embodiments the
selector switch 181 rests in its current state, so when it is
selected to close second pores 135, the second pores 135 are
selectively closed then and the switching action remains in
position until altered from this state. The selective mouthpiece
lid 104s may be coupled with the device body 102 in either of the
first or second orientations as determined by the user. With the
selective mouthpiece 104s either both or one of the chambers may be
selected for having vapor drawn therefrom.
[0095] Referring to FIGS. 1F and 1E, in some embodiments, such as
shows for the DCVD 100 and DCVD 200, the common air intake manifold
191 receives ambient air 555 through an ambient air input port 125
and this ambient air is split by the air intake manifold 191 into a
first airpath 167 that that may be for propagating through the
first heating chamber 106 through the a first chamber third
sidewall 108c via first chamber pores 106p a and a second airpath
168 may be for propagating into the second heating chamber 206
through the third sidewall 208c via second chamber pores 206p.
[0096] Referring to FIGS. 1O and 1K. the first and second airpaths
167 and 168 both meet at the air cooling assembly 124 when the
mouthpiece lid 104 or selective mouthpiece lid 104s is in the
closed position in either the first or second orientation. In some
embodiments the common air intake manifold 191 receives ambient air
555 and is split by the air intake manifold 191 into the first
airpath 167 that is for propagating through the first heating
chamber 106 and the second airpath 168 for propagating through the
second heating chamber 206 where the first and second airpaths
selectively meet at the air cooling assembly 124 when the selective
mouthpiece lid 104s is in the closed position, unless the selective
mouthpiece lid 104s has the selector switch 181 oriented for
selectively closing second pores 220p from having air flow through
the pores to the air cooling assembly 124.
[0097] Referring to FIG. 1E, a size of the first chamber pores 106p
and size of the second chamber pores 206p may vary depending on the
form of the phyto material to be vaporized. An optimal pore size
may depend on the fineness of the phyto material loaded into the
first chamber cavity 120 (i.e. the finer the grind, the smaller the
pores 132). Smaller pores 106p may inhibit non-vaporized pieces of
the phyto material from falling through first chamber third
sidewall 108c via the first chamber pores 106p and into the common
air intake manifold. For the second heating chamber 206 the second
chamber pores 206p may also be of a smaller or larger size than the
first chamber pores 106p.
[0098] In some embodiments a removable drawer 278 may be provided
for collecting phyto material that falls through the first chamber
pores 106p, where in some cases there is a tradeoff between the
pore size as well as airflow. The smaller the pore size the more
the airflow is restricted. As such having a removable drawer 278
facilitates cleaning of crumbs or phyto material that has fallen
out of the heating chamber through the first chamber pores 106p.
When the removable drawer is removed is also facilitates cleaning
of any residue or wax building that may have propagated from the
second heating chamber through the second chamber pores 206p into
the common air intake manifold 191. In some embodiments, the pores
106p and pores 206p may be between 0.1 and 0.6 mm. For example, the
pores 106p and pores 206p may be between 0.025 and 0.3 mm. In some
embodiments, the pores 106p and pores 206p may be between 0.3 and
0.9 mm. In some embodiments, such as for the second heating
chamber, a porous ceramic or porous metal is envisaged for creating
of the second chamber pores 206p.
[0099] Referring to FIG. 1E, in some embodiments, the first heating
chamber may include a conduction heating system, the first heating
element assembly 112 may be positioned to at least partially
surrounding the exterior of the first heating chamber 106. The
first heating element assembly 112 may be energized to emit heat.
The heat from the first heating element assembly 112 may heat the
first chamber cavity 120, and in turn the phyto material positioned
in the first chamber cavity 120. In some embodiments, the first
heating element assembly 112 may include one or more resistive
heating elements sintered with the ceramic heating chamber. In some
embodiments the heating element assembly 112 includes a coil
heating element 115. The coil heating element 115 may be activated
by directing current through the coil 115. The coil 115 may then
emit heat. Heat from the first heating element assembly 112 may
radiate into the first heating chamber 106 to heat phyto material
419 in the first chamber cavity 120 to a first predetermined
vaporization temperature. Phyto material vapor may then be emitted
from the heated material. In some embodiments an insulating layer
is provided between the two heating chambers.
[0100] The first heating element assembly 112 may be formed from a
silk screen resistive film heating whereby a heating element is
formed from a resistive ink that is integrated and sintered with
the heating chamber being manufactured from ceramic or where it's a
resistive wire wrapped about an outside of the heating chamber or
the heating chamber is manufactured from deep drawn or stamped or
cast metal and the first heating element assembly 112 is printed
onto the heating chamber and integrated therewith where in the case
where the first heating chamber 106 is tubular in shape, a Thick
Film Tubular Heater (TFH) is printed on stainless steel substrate
by using a thick-film screen printing process to print insulating
materials, heating resistors, conductors and then a glass
protective glaze. In the case of a rectangular heating chamber or a
heating chamber with flat walls, a Thick Film Flat Heater (FTH)
process may be used. The FTH may be printed on stainless steel
substrate by using a thick-film screen printing process to print
insulating materials, heating resistors, conductors, glass
protective glazes. A capton heater may also be envisaged with a
capton resistive heating element wrapped about the first heating
chamber 106.
[0101] For a convection heating system being utilized within the
DCVD 100, 200, a third heating element assembly may be provided in
the form of a thermal radiator 1806 (FIG. 3B) for receiving of
incoming air and for heating the incoming air through a convective
heat transfer process where the thermal radiator 1806 may be
energized to emit heat and the heat from the thermal radiator 1806
may heat the phyto material positioned in the first chamber cavity
120 through a convective heating process. The thermal radiator 1806
may or may not be utilized in conjunction with the first heating
element assembly 112. Embodiments of convection heating system are
further described in FIGS. 3A, 3B, 3C.
[0102] Referring to FIG. 1P, in some embodiments, the second
heating element assembly 212 may include one or more resistive
heating elements as the second heating element assembly 215
removably (using releasable electrical coupling 161 (FIG. 1P, 1E))
or fixed mounted within the second heating chamber 220. In some
embodiments the second heating element assembly 212 includes a
resistive coil heating element 315, which may be in the form of a
pancake resistive coil or a spiral coil or a printed coil. The
resistive coil heating element 315 may be activated by directing
current through the coil 315. The coil 315 may then emit heat. Heat
from the heating element assembly 212 may radiate into the second
heating chamber 206 to heat phyto material extract 421 in the
second chamber cavity 220 to a second predetermined vaporization
temperature through direct contact (shown more clearly in FIG. 1H)
with the phyto material extract. Phyto material extract vapor as
the second vapor may then be emitted.
[0103] The second heating element assembly 212 may be removable
from the second heating chamber with electrical contacts that are
pin or screw or magnetic based so that in the case it fails or gets
dirty it may be removed. The resistive coil heating element 215 may
be directly in contact with the phyto material extract or as shown
in FIG. 1H in a cutaway side view. Referring to FIG. 1P, the
resistive coil heating element 315 may be in thermal contact with a
glass or ceramic or quartz dish or bucket, generally referred to as
a bucket 313 having an inner volume 312, that may be surrounded by
porous ceramic or porous metal 314 material or an air gap or a
combination of an insulating material and air channel formed
between an outside surface of the bucket 313 or dish and an inside
surface of a shroud assembly 391 and an air gap between the that
generally allows for air to propagate about an outside diameter or
outside shape of the bucket 313 and an inside surface of the shroud
assembly 391 that faces the bucket 313. The heating element
assembly and the 215 the bucket 313 are held in place and
preferably somehow thermally insulated from the shroud assembly
391. The electrical contacts that are pin or screw or magnetic base
are mechanically coupled with the shroud assembly 391.
[0104] The second airpath 168 may be for propagating into the
second heating chamber 206 to the first end 206a through second
chamber third sidewall 208c via the second chamber pores 206p and
at least one of a gap 392 between walls of the second chamber
cavity 220 and an outside surface of the shroud assembly 391 and
through the porous ceramic or porous metal 314 material or an air
gap or a combination of an insulating material and air channel
formed between an outside surface of the bucket 313 and an inside
surface of a shroud assembly 391. Air propagating through the
second heating chamber 206 in accordance with either of the above
means may provide for thermally insulating of the glass bucket from
the shroud assembly as well as may assist in thermally insulating
(at least partially) of the shroud assembly from inner walls of the
second heating chamber. This may facilitate a quicker heating of
the glass bucket. Advantageously the glass bucket may provide for a
cleaner vaporization of the phyto material extracts as the second
vapor as opposed to the phyto material extracts being paced
directly onto the coil heater 212.
[0105] A releasable electrical coupling 161 (FIG. 1P, 1E) may be
provided for the removably mounting of the second heating element
assembly 221 from the device body 102. This facilitates removing of
the second heating element assembly 221 when it may need
replacement. Preferably the resistive wire is insulated from
sidewalls of the second heating chamber 206. so that a larger
amount of thermal energy from the resistive wire is transferred to
the phyto material extract that is disposed within the bucket
rather than to sidewalls of the second heating chamber 206 and also
potentially into the shroud assembly. For an extract conduction
heating system, the second heating element assembly 212 may be
positioned to heat an interior of the second heating chamber 206.
In some embodiments the shroud assembly and the bucket may be
cylindrical in shape and coaxial with one another.
[0106] Referring now to FIGS. 2A-2E, a DCVD 300 in accordance with
a third embodiment shown. The DCVD 300 300 is another example of a
vaporization device usable to vaporize vaporizable material.
Vaporization device 300 having similar structure and/or performing
similar function as those in the example vaporizer device 100 of
FIGS. 1A through 1P are numbered similarly, with the reference
numerals incremented by 200.
[0107] Referring to FIG. 2A the DCVD 300 may include a device body
302 that may include a heating unit that includes a first heating
chamber 306 and a first heating element assembly 312 thermally
coupled with the first heating chamber 306 and second heating
element assembly 412 disposed within the second heating chamber
406. The first heating element assembly 312 may be positioned
adjacent to the first heating chamber 306 and may be positioned
about the first heating chamber for a conduction based vaporization
device. The first heating element assembly 312 may be used to heat
regions of the first heating chamber 306 for heating of a first
material for vaporization disposed therein with a first source of
heat.
[0108] The device body 302 may have a heating unit that includes
the second heating chamber 406 and the second heating element
assembly 412. The second heating element assembly 412 may be for
heating of phyto material extract, or a second material for
vaporization, such as a wax or resin and may be a conduction style
heating for directly conducting of heat to the phyto material
extract from the second heating element assembly 412. The second
heating element assembly 412 may include a resistive coil heating
element 415 thermally coupled with a bowl or a bucket for
containing of the phyto material extract and sidewalls of the
second heating chamber may be manufactured from a ceramic or glass
or metal. The bowl or a bucket for containing of the phyto material
extract may be manufactured from a ceramic or glass or metal with a
resistive heating from a floor of the ceramic or glass or metal
bucket. The second heating chamber 406 may include a first end
406a, a second end 406b. The second heating chamber 406 may also
include one or more second chamber sidewalls 406s extending from
the first end 406a to second end 406. The sidewalls may define a
second chamber cavity 420 of the second heating chamber 406. Phyto
material extract may be loaded to the second heating element 412 of
the second chamber cavity 420 in preparation for vaporization. The
second heating element assembly may be disposed within the second
heating chamber for applying a source of a second heat through a
thermal conduction process to the second material for
vaporization.
[0109] The first heating chamber 306 may be cylindrical. The first
heating chamber 306 may include first chamber sidewalls 306s,
extending from the first end 306a to the second end 306b, which may
be a cylindrical sidewall 308a extending from the first end 306a to
the second end 306b. The first heating chamber 306 may also include
a first chamber third sidewall 308c capping first heating chamber
306 at the second end 306b that may also be referred to as a base
or floor. This may allow air to flow into the first chamber cavity
320 of first heating chamber 306. First heating chamber 306 may
also have an open upper end or side 306d. Phyto material may be
loaded into the first chamber cavity 320 through this open upper
end 306d.
[0110] In some embodiments the second heating chamber 406 and the
second heating element assembly 412 is may be for operating at a
higher temperature than the first heating element assembly 312. The
first heating chamber 306 may be for use with ground phyto material
and the second heating chamber 406 may be for use with phyto
material extract.
[0111] The mouthpiece lid 304 may be moved between an open position
(shown in FIG. 2A) and a closed position (FIG. 2D). In the open
position, the upper end of the first chamber cavity 320 may be
exposed. This may allow a user to load phyto material 419 into the
first heating chamber 306 and phyto material extract 421 into the
second heating chamber 406 for vaporization and/or dispose of
vaporized phyto material therefrom. The mouthpiece lid 404 may also
be rotated about a vertical axis/central axis 512 where the
mouthpiece portion proximate the first and second cavities, 320 and
420 may have a symmetry and may magnetically or frictionally engage
with the body 302 in either one of two orientations. In this third
embodiment the mouthpiece lid 304 may be substantially symmetric
about the vertical axis or central axis 512.
[0112] Referring to FIG. 2A, in the first orientation the
mouthpiece lid 304 may include a first perforated floor section
320p to be aligned with the first end 306a of the first heating
chamber 306 and a second perforated floor section 420p may be
aligned with the first end 406a of the second heating chamber 406.
Referring to FIG. 2B, in the second orientation the mouthpiece lid
304 may include the first perforated floor section 420p to be
aligned with the first end 306a of the first heating chamber 306
and a first perforated floor section 320p may be aligned with the
first end 406a of the second heating chamber 406. When the
mouthpiece lid 304 is moved to the closed position and in the first
orientation, the mouthpiece lid 304 and the first heating chamber
306 and the second heating chamber 406 may enclose the first and
second chamber cavities 320, 420. When the mouthpiece lid 304 is
moved to the closed position and in the second orientation, the
mouthpiece lid 304 and the first heating chamber 306 and the second
heating chamber 406 may enclose the first and second chamber
cavities 320, 420.
[0113] FIG. 2N illustrates the mouthpiece lid 304 in an exploded
perspective view and FIG. 2C from an exploded side view. Referring
to FIG. 2A, the first perforated floor section 320p of mouthpiece
lid 304 may also include apertures or first pores 334 throughout
its surface and the second perforated floor section 420p of
mouthpiece lid 304 may also include apertures or second pores 335
throughout its surface. When in the first orientation and when the
mouthpiece 304 is in the closed position the first pores 334 may
permit first vapor or first aerosol to pass from the first chamber
cavity 320 to an inner lid space 322 (FIG. 2B) through the first
perforated floor section 320p and for second vapor or second
aerosol to pass from the second chamber cavity 420 to an inner lid
space 322 through the second perforated floor section 420p having
second pores 335. When in the second orientation and when the
mouthpiece 304 is in the closed position the first pores 334 may
permit second vapor to pass from the second chamber cavity 420 to
an inner lid space 322 through the first perforated floor section
320p and for the first vapor to pass from the first chamber cavity
320 to the inner lid space 322 through the second perforated floor
section 420p. The first heating element assembly may result in the
first material for vaporization to generate a first aerosol and the
third heating element assembly may result in the first material for
vaporization to generate a third aerosol where at least one of the
second and third aerosol form the first vapor.
[0114] The size of first pores 334 and second pores 335 may be
selected to inhibit non-vaporized pieces or flakes of the phyto
material from passing into the air cooling assembly 324 and out the
inhalation aperture 330 into the user's mouth. Thus, the first
pores 334 may also provide a filtering action. The first pores 334
in conjunction with optionally the air cooling assembly 324 may
also provide a filtering action through a shape of the air cooling
assembly 324 may provide for a mixing air path or a cascade mixing
air path or a tortuous air path. In some embodiments a first air
cooling path length formed between the first perforated floor
section 320p and the inhalation aperture 330 may be shorter than a
second air cooling path length formed between the second perforated
floor section 420p and the inhalation aperture 330 and in some
embodiments the first and second cooling path lengths combine
towards the mouthpiece to mix vapors emitted from both heating
chambers as part of a mixing air path. The air cooling assembly 324
may be manufactured from an elastomeric material or a combination
of an elastomeric material and a metal material where in conduction
with the inner lid space 322, vapors propagating from each of the
perforated floor sections, 320p, 420p, may be cooled. In some
embodiments the mouthpiece 304 may be manufactured from a metal or
aluminum material. First and second vapors may lose heat to the air
cooling assembly 324 as well as the mouthpiece 304.
[0115] The user may be able to adjust between the first orientation
(FIG. 2A) of the mouthpiece lid 304 and the second orientation
(FIG. 2B) of the mouthpiece lid 304 in order to select from which
cavity 320, 420 additional vapor cooling is preferred. The size of
first pores 334 and 335 may depend on the form of the phyto
material being used and may not be equal in all cases. In some
embodiments, the first pores 334 may be between 0.1 and 0.6 mm. For
example, the first pores 334 may be between 0.025 and 0.3 mm. In
some embodiments, the first pores 334 may be between 0.05 and 0.2
mm and in other cases 0.8 mm. In some embodiments the first
perforated floor section 320p and the second perforated floor
section 420p may have first pores 334, 335 of varying sizes. The
size of first pores 334 may be selected to inhibit non-vaporized
pieces or flakes of the phyto material from passing into the air
cooling assembly 324 and out the inhalation aperture 330 into the
user's mouth. Thus, the pores 134 may also provide a filtering
action as well as somewhat cooling action. The first pores 334 in
conjunction with the air cooling assembly 324 may also provide a
filtering action through a shape of the air cooling assembly 324
that uses the mixing air path. A combined length of the airpath
long which air and vapor travels is greater than a distance between
the inhalation aperture 330 and a mouthpiece base or height 304h of
the mouthpiece 304.
[0116] Referring to FIG. 2A. a first airpath 267 and a second
airpaths 268 both meet at the air cooling assembly 324 when the
mouthpiece lid 304 is in either the first or second orientation. In
some embodiments an air intake manifold 391 receives ambient air
555 through a first ambient air input port 325 and air flows
through the first airpath 267 for propagating through the first
heating chamber 306. Ambient air 555 may originate to the second
airpath 268 via a second ambient air input port 326 for propagating
across the second heating chamber 406 proximate the first end 406a
and approximately radially with respect to the heating unit 412 for
skimming vapors proximate the first end 406a that are emitted by
the second heating unit 412 with the where the first and second
airpaths 267 and 268 meet at the air cooling assembly 324 when the
mouthpiece lid 304 is in the closed position. In some embodiments
the second airpath 268 other than originates from the air intake
manifold 391. The second ambient air input port 326 may include a
selectable airflow restrictor 399 (FIGS. 2B, 2D and 2E) where in
some embodiments the selectable airflow restrictor 399 is movable
to approximately restrict incoming ambient airflow into the second
airpath 268 or to allow approximately maximal airflow into the
second airpath 268. The selectable airflow restrictor 399 may
operate from an opening of approximately 0.1 mm{circumflex over (
)}2 in area to an opening of approximately 5 mm{circumflex over (
)}2 in area for the second ambient air input port 326. The
selectable airflow restrictor 399 may be a rotating collar about
sidewalls 406s of the second heating chamber 406 or in some
embodiments it may be a slider for varying an aperture through
which the second airpath 268 originates for controlling an area of
the second ambient air input port 326.
[0117] The user may be able to selectively control the airflow
incoming into the second heating chamber 406 through the selectable
airflow restrictor 399 and to control the airflow incoming into the
first heating chamber 306 using the first ambient air input port
325. Through blocking of the first ambient air input port 325, for
example by using a finger, substantially little airflow flows into
the first heating chamber 306. Through blocking of the second
ambient air input port 326 for example by using the selectable
airflow restrictor 399 such that it may be oriented so that little
airflow flows into the second heating chamber 406. The user may
then able to control amounts of vapor being emitted from each of
the first and second heating chambers.
[0118] The mouthpiece lid 304 may be movably mounted to the device
body 302 by a friction fit connection such as that described for
the first and second embodiments. In other embodiments, the body
302 may have a protruding lip 302L around an outer edge 302a. The
mouthpiece lid 304 may be sized to fit within the protruding lip
302L and outer edge and may be held in place by friction along the
protruding lip edge, in other embodiments a magnetic coupling may
be realized between the mouthpiece lid 304 and the device body 302.
In some embodiments a first ring magnet may be disposed about the
mouthpiece lid 304 may about the first perforated floor section
320p to be aligned with the first end 306a of the first heating
chamber 306 and a second ring magnet may be disposed second about
the second perforated floor section 420p to be aligned with the
first end 406a of the second heating chamber 406. The ring magnets
may engage the first end 306a of the first heating chamber 306 and
may engage the first end 406a of the second heating chamber 406
where these surfaces may include a metallic surface for engaging
with the ring magnets. First and second elastomeric seals 386 and
486 may be formed about the first and second perforated sections
320p and 420p of the mouthpiece lid 304 for sealing the mouthpiece
lid 304 against the device body 302 when the mouthpiece lid 304 is
frictionally or magnetically engaged with the device body 302 for
allowing a user to create a vacuum at the inhalation aperture 330
for sucking of vapors originating from at least one of the first
and second heating chambers 306 and 406. The elastomeric material
seals 386 and 486 may facilitates of vapor transfer from the first
and second heating chambers, 306 and 406, into the air cooling
assembly 324. The mouthpiece lid 304 may contain an indent 304i or
a tab to enable the user to remove the mouthpiece lid 304.
[0119] Referring to FIG. 2B, a separator rib 356 formed between the
first heating chamber cavity 320 first end 306a and the first end
406a of the second heating chamber cavity 420 where the separator
rib 356 may be for creating a raised protrusion between the first
and second cavities, 320 and 420. This separator rib 356 may assist
a user in loading of phyto material into either one of the chambers
so that for example the loose leaf phyto material does not go into
an undesired heating chamber cavity. The separator rib 356 may also
protrude into a separator rib cavity 357 that may be formed as a
cavity in the mouthpiece lid 304 so that material from one chamber
may have less of a likelihood of flow between chambers when the
DCVD 300 is inverted. In some embodiments the separator rib 356,
156 may be raised about 3 mm in height and have a length of about
10 mm and a width of about 3 mm. In some embodiments the separator
rib 356 may be made from a magnetic metal and there may be magnets
inside the mouthpiece lid that engage the separator rib 356 when
inserted into the separator rib cavity 357.
[0120] The DCVD 300 may also include a control circuit similar to
the control circuit 114 may also manage the operation of other
components of DCVD 300 such as user input controls 997, such as
buttons, such as a temperature up button 997a and a temperature
down button 997b and a second heater button 997c to control power
applied to the second heating element assembly 412 as well as a
power ON/OFF button 997d. The DCVD 300 may include one or more
output components 499 (such as an OLED display) that provide visual
signals to a user regarding the configuration and settings of DCVD
300. The second heating element assembly 412 may be similar to the
second heating element assembly 212.
[0121] In some embodiments, the heating element assembly may be
configured to heat the phyto material to a first predetermined
vaporization temperature. The first predetermined vaporization
temperature may vary depending on user preference and/or the form
of the phyto material. For example, loose leaf phyto material may
be vaporized at a predetermined vaporization temperature in a range
between about 320 degrees Fahrenheit and about 450 degrees
Fahrenheit. The user may be able to adjust the first predetermined
vaporization temperature using input controls. The control circuit
114 may then control the current through the first heating element
to adjust the first vaporization temperature.
[0122] In some embodiments, the heating element assembly may be
configured to heat the phyto material extract to a second
predetermined vaporization temperature. The second predetermined
vaporization temperature may vary depending on user preference
and/or the form of the phyto material extract. For example, phyto
material extract may be vaporized at a second predetermined
vaporization temperature in a range between about 450 degrees
Fahrenheit and about 750 degrees Fahrenheit. The user may be able
to adjust the second predetermined vaporization temperature using
input controls. The control circuit 114 may then control the
current through the second heating element to adjust the second
vaporization temperature. In some embodiments the battery 116 may
have the heating chambers extend along its length and may share a
common central axis and the heating chambers may be oriented
parallel with each other and inline with the battery. In some
embodiments the heating chambers may be oriented perpendicular with
a long axis of the battery and a mouthpiece extending across the
battery along its length and proximate a battery removal port
912.
[0123] Referring now to FIG. 2F, a DCVD 500 in accordance with a
fourth embodiment is shown. The DCVD 500 is another example of a
vaporization device usable to vaporize vaporizable material.
Vaporization device 500 having similar structure and/or performing
similar function as those in the example vaporizer device 300 shown
in FIGS. 2A to 2E, similar figure numbers from the third embodiment
are incremented by 200. The DCVD 500 may include a device body 502
that may include a heating unit that includes a first heating
chamber 506 and a first heating element assembly (not visible)
thermally coupled with the first heating chamber 506 and second
heating element assembly (not visible) disposed within the second
heating chamber 606. The first heating element assembly 312 may be
positioned adjacent to the first heating chamber and may be
positioned about the first heating chamber for a conduction based
vaporization device. The first heating element assembly 312 may be
used to heat regions of the first heating chamber 306.
[0124] The device body 502 may have a heating unit that includes
the second heating chamber 606 and the second heating element
assembly. The second heating element assembly may be for heating of
phyto material extract such as a wax or resin and may be a
conduction style heating for directly conducting of heat to the
phyto material extract from the second heating element assembly.
The second heating element assembly (such as that shown in FIG. 1P)
include a resistive coil heating element thermally coupled with a
bowl or a bucket for containing of the phyto material extract and
sidewalls of the second heating chamber may be manufactured from a
ceramic or glass or metal. The bowl or a bucket for containing of
the phyto material extract may be manufactured from a ceramic or
glass or metal with a resistive heating from a floor of the ceramic
or glass or metal bucket. The second heating chamber 606 may
include a first end 606a, a second end (not shown). The second
heating chamber 606 may also include one or more second chamber
sidewalls 606s extending from the first end 606a to the second end
(not shown) with a second chamber third sidewall (not shown)
capping the second heating chamber 606 proximate the second end.
The first heating chamber 506 may also include one or more first
chamber sidewalls 506s extending from the first end 506a to the
second end (not shown) with a first chamber third sidewall (not
shown) capping the first heating chamber 506 proximate the second
end. The first heating chamber 506 may be cylindrical. The first
heating chamber 506 may include a cylindrical sidewall extending
from the first end 506a to the second end. The first heating
chamber 506 may also include a first chamber third sidewall 308c
capping the heating chamber at the second end that may also be
referred to as a base or floor. This may allow air to flow into the
first chamber cavity 520 of first heating chamber 506. First
heating chamber 306 may also have an open upper end or side 306d.
Phyto material may be loaded into the first chamber cavity 320
through this open upper end 306d.
[0125] An air cooling chamber lid 504 may be moved between an open
position (shown in FIG. 2A) and a closed position (not shown). It
would be evident to the reader that FIG. 2A shows an open position
and in a closed position the first and second heating chambers, 506
and 606, are covered by the air cooling chamber lid 504. In the
open position, the user may load ground phyto material into the
first heating chamber 506 and phyto material extract into the
second heating chamber 606 for vaporization and/or dispose of
vaporized phyto material therefrom. The air cooling chamber lid 504
may also be magnetically coupled with the device body 502 or it may
be hinged with the device body or in some embodiments in may
frictionally engage with the device body 502.
[0126] The air cooling chamber lid 504 may include a first
perforated floor section 520p to be aligned with the first end 506a
of the first heating chamber 506 and a second perforated floor
section 620p may be aligned with the first end 606a of the second
heating chamber 606. When air cooling chamber lid 504 is moved to
the closed position and in the first orientation, air cooling
chamber lid 504 and the first heating chamber 506 and the second
heating chamber 606 may enclose the first and second chamber
cavities 520, 620. When air cooling chamber lid 504 is moved to the
closed position, the air cooling chamber lid 504 and the first
heating chamber 506 and the second heating chamber 606 may enclose
the first and second chamber cavities 520, 620.
[0127] The first perforated floor section 520p of air cooling
chamber lid 504 may also includes apertures or first pores 534
throughout its surface and the second perforated floor section 620p
of air cooling chamber lid 504 may also includes apertures or
second pores 535 throughout its surface. When the air cooling
chamber lid 504 is in the closed position the pores 534 may permit
vapor to pass from the first chamber cavity 520 to an inner lid
space 522 through the first perforated floor section 520p and for
the vapor to pass from the second chamber cavity 620 to an inner
lid space 522 through the second perforated floor section 620p
having pores 535.
[0128] A size of pores 534 and 535 may be selected to inhibit
non-vaporized pieces or flakes of the phyto material from passing
into the air cooling assembly 524 and out an inhalation aperture
530 into the user's mouth. Thus, the pores 534 may also provide a
filtering action. The pores 534 in conjunction with an optionally
utilized air cooling assembly (not shown) may also provide a
filtering action through a shape of the air cooling assembly may
provide for a mixing air path. The inner lid space 522 is fluidly
coupled with the inhalation aperture 530 when the air cooling
chamber lid 504 is approximately fluidly sealed against the first
and second heating chambers where the first heating chamber 506 and
the second heating chamber 606 may enclose the first and second
chamber cavities 520, 620. Vapor emitted from the first heating
chamber 506 and the second heating chamber 606 may propagate
approximately parallel with a battery container therein and out
from the mouthpiece 530 proximate a battery removal port 912.
[0129] In some embodiments a first air cooling path length formed
between the first perforated floor section 520p and an inhalation
aperture 530 may be shorter than a second air cooling path length
formed between the second perforated floor section 620p and the
inhalation aperture 530 and in some embodiments the first and
second cooling path lengths combine towards the mouthpiece 530
along the inner lid space 522 to mix vapors emitted from one of or
both heating chambers as part of a mixing air path. Vapors may lose
heat as they propagate within the inner lid space 522 and in some
embodiments through the air cooling assembly as well as the
mouthpiece 504. Ambient air flowing into either of the heating
chambers may be similar to that shown in the first, second or third
embodiments. The inner lid space 522 may include an air and vapor
outlet 526 that is fluidly connected to the inhalation aperture 530
when in the closed position (not shown) and other than fluidly
connected to the inhalation aperture 530 when in the open position
(as shown).
[0130] In some embodiments, as shown in FIG. 1F, a partial cutaway
of the vaporization device 100 is shown with the mass airflow
sensor (MAF) 888 or a puff sensor, or a barometric pressure sensor
may be coupled to the air intake manifold 191, when the user draws
then ambient air 555 may be drawn from the external environment 144
and propagated past ports of the mass airflow sensor 888. With
calibration, the MAF 888 is able to determine a mass of air that is
drawn into one or both of the heating chambers and this may be
useful for determining dosing. Where data generated by the MAF may
then be wirelessly transmitted to a smartphone device 998 or a data
server. This MAF 888 is also applicable to the other
embodiments.
[0131] Referring now to FIG. 3A there is shown a vaporization
device (VD) 600 in accordance with a fifth embodiment of the
invention. The VD 600 may include a device body 1102 and a
mouthpiece lid 1104 can be moveably mounted to device body 1102
(hinged or friction fit or slid on) as described in other
embodiments. The device body 1102 may include a convection and
conduction heating unit (CCHU) 1103 that includes a first heating
chamber 1106 for receiving of ground phyto material 419. When the
mouthpiece may be removed from the device body 1102, then the first
heating chamber 1106 may be accessible for loading and unloading of
ground phyto material 419. The mouthpiece lid 1104 may include an
inhalation aperture 1130 and an inner lid space 1222 for receiving
of first and second vapors and a may include an air cooling
assembly 1224 therein where vapor passes into the inner lid space
1222 via a perforated floor section of mouthpiece lid (not visible
in this figure, however its shown in the other embodiments) may
also includes apertures or pores (not shown in this figure)
throughout its surface. The pores may permit vapor to pass from the
chamber cavity 1120 to the inner lid space 1222. The size of pores
may be selected to inhibit non-vaporized pieces or flakes of the
phyto material from passing into an air cooling assembly 1224 and
out the inhalation aperture 1130 into the user's mouth. Thus, the
pores may also provide a filtering action. The pores in conjunction
with the air cooling assembly 1124 may also provide a filtering
action through a shape of the air cooling assembly as well as vapor
and air travel pathlength. It will be appreciated by the reader
that the VD 600 may also include the second heating chamber and
associated components as explained in the aforementioned
disclosure. Similarly the CCHU 1103 as outlined hereinbelow may
include the first heating chamber as explained in the embodiments
hereinabove.
[0132] Referring to FIG. 3B, a first conduction convection heating
unit the CCHU 1103 may be provided in accordance with an embodiment
of the invention and may be used with the VD 600 in accordance with
a fifth embodiment of the invention as shown in FIG. 3A. The CCHU
1103 may include a first heating chamber 1106 can include a first
end 1106a, a second end 1106b. The first heating chamber 1106 may
also include one or more sidewalls 1106c extending from the first
end 1106a to the second end 1106b. The sidewalls as well as a base
or floor 1108c or first chamber third sidewall 1108c or base may
define a chamber cavity 1120 of the first heating chamber 1106.
Ground phyto material may be loaded to the chamber cavity 1120 in
preparation for vaporization. A floor of the chamber cavity 1120
may be perforated and include first chamber third sidewall pores
1134. This may allow heated air to flow into the chamber cavity
1120 of first heating chamber 1106.
[0133] In the example shown in FIGS. 3A and 3B, 3C and 3E, the
chamber cavity 1120 and the first heating chamber 1106 may be
cylindrical in shape. First heating chamber 1106 may include a
cylindrical sidewall 1108a extending from the first end to the
second end. First heating chamber 1106 may also include a third
sidewall 1108c capping the cylindrical heating chamber at the
second end that may also be referred to as a base or floor. The
base sidewall 1108c may be perforated with first chamber third
sidewall pores 1134. First chamber third sidewall 1108c may have an
open upper end or side 1106d. Phyto material that is ground may be
loaded into the chamber cavity 1120 through this open upper end.
The base sidewall 1108c may be perforated with first chamber third
sidewall pores 1134, the size of first chamber third sidewall pores
1134 may depend on the form of the phyto material being used. In
some embodiments, the first chamber third sidewall pores 1134 may
be between 0.1 and 0.6 mm. For example, the first chamber third
sidewall pores 1134 may be between 0.025 and 0.3 mm. In some
embodiments, the first chamber third sidewall pores 1134 may be
between 0.05 and 0.2 mm.
[0134] The CCHU 1103 may includes a first heating element assembly
1112 in thermal conduction coupled with the first heating chamber
1106 between the first and second ends thereof 1106a and 1106b. The
first heating element assembly 1112 (FIG. 3C) may be formed about
the first heating chamber 1106 on an outside thereof, opposite a
side that contacts the ground phyto material. The first heating
chamber 1106 may be manufactured from ceramic and the heating
element assembly 1112 may be formed from a silk screen resistive
film heating whereby a heating element is formed from a resistive
ink that is integrated and sintered about the outside of the first
heating chamber 1106 and with the heating chamber being
manufactured from ceramic. In a variation, a resistive wire may be
wrapped about an outside the first heating chamber 1106. In the
case the first heating chamber 1106 may be manufactured from
ceramic the third sidewall 1108c may be manufactured from ceramic
or metal.
[0135] The heating chamber may be manufactured from a metal, such
as stainless steel, and manufactured from deep drawn or stamped or
cast metal and the heating element assembly 1112 is printed onto
the heating chamber and integrated therewith where in the case
where the first heating chamber 1106 is tubular in shape, a Thick
Film Tubular Heater (TFH) may be printed on stainless steel
substrate by using a thick-film screen printing process to print
insulating materials, heating resistors, conductors and then a
glass protective glaze. In the case of a rectangular heating
chamber or a heating chamber with flat walls, a Thick Film Flat
Heater (FTH) process may be used. The FTH may be printed on
stainless steel substrate by using a thick-film screen printing
process to print insulating materials, heating resistors,
conductors, glass protective glazes.
[0136] Optionally the first heating element assembly 1112 may be
formed using a capton heater about a phyto material contact surface
1196 as part of the first heating chamber 1106 that may be disposed
inside of the first heating chamber 1106. FIG. 3B illustrates an
exploded view that includes the heating element assembly 1112 and
the phyto material contact surface 1196 where in FIG. 3C the CCHU
1103 is shown in a non exploded view. The first heating element
assembly 1112 in conjunction with the phyto material contact
surface 1196 heating chamber may provide a first source of heat
upon converting of electrical energy to thermal energy to the
receiving ground phyto material 419 when subjected to first source
of heat at a predetermined first temperature range, when the ground
phyto material 419 may be disposed within the first heating chamber
1106. The first source of heat may be provided by conductive
heating of the ground phyto material 419 through direct contact
with cylindrical sidewalls of the heating chamber as well as
radiation heating from the cylindrical sidewalls. Optionally a
temperature sensor is provided to sense a temperature of the
heating element assembly 1112 for stabilizing a temperature thereof
in a PID control loop. The phyto material contact surface 1196
provides for forming of the chamber cavity 1120 with the one or
more sidewalls 1106s that extend from the first end to the second
end and include a third sidewall 1108c capping the first heating
chamber 1106 at the second end 1106b.
[0137] A second source of heat is provided by a thermal radiator
1806 may be provided upstream of first heating chamber 1106 and
proximate the base sidewall 1108c. The thermal radiator 1806 may
include a third heating element assembly 1816 centrally disposed
within a first insulating sheath 1170 for converting of electrical
energy to thermal energy for being conductively thermally coupled
with the thermal radiator 1806 for heating of the thermal radiator
806 for the thermal radiator to radiate heat therefrom as the
second source of heat through the first chamber third sidewall
pores 1134.
[0138] The first insulating sheath 1170 may be provided about an
outer circumference or about an outside of the thermal radiator
1806 and may not be in a conductive thermal coupling with the
thermal radiator 1806. The first insulating sheath may include a
first end 1170a that may be coupled with the first heating chamber
1106 proximate the base sidewall 1108c and it may include an inner
surface. The thermal radiator 1806 may be centrally located within
the first insulating sheath 1171 and at a separation from the inner
surface of the first insulating sheath 1171. As well the thermal
radiator 1806 may be separated from the base sidewall 1108c and a
gap may exist between the thermal radiator 1806 and the base
sidewall 1108c. The thermal radiator may include a first end 1806a
that may be proximate to the base sidewall 1108c and a second end
1806b opposite the first end 1806a. A second end cap 1182 may be
provided for maintaining the thermal radiator in being separated
from the base sidewall 1108c and the inner surface of the first
insulating sheath 1171. The thermal radiator may radiate heat
towards the inner surface of the first insulating sheath 1171 as
well as towards the base sidewall 1108c for the radiated heat to be
applied to the ground phyto material as the second source of heat
through the first chamber third sidewall pores 1134. The first
insulating sheath 1170 may be formed from a PAI (polyamide-imide)
or a high temperature thermoplastic material. The first insulating
sheath 1171 may include a first end 1171a for coupling with the
first heating chamber 1106 proximate the second end 1106b and a
second end 1171a opposite the first end 1171b. The thermal radiator
1806 may be disposed between the first end 1171a and the second end
1171b. The thermal radiator 1806 is for providing a source or third
heat.
[0139] A first thermal insulating layer 1161 (shown in FIG. 3E) may
be wrapped about the first insulating sheath 1171 and the first
heating chamber 1106 where the first thermal insulating layer 1161
may extend proximate the first end 1106a to proximate the first
insulating sheath 1170 second end 1171a. The first thermal
insulating layer 1161 may be for reducing a transfer of thermal
energy between objects of differing temperatures. A heating unit
wall assembly 1199 may be provided for surrounding the first
thermal insulating layer 1161 and disposed between the proximate
the first end 1106a of the first heating chamber 1106 to proximate
the first insulating sheath 1170 second end 1171a. A first end cap
1181 may be couple with the heating chamber first end 106a and to
thermally insulate the first heating chamber 1106 from a first end
1199a of a heating unit wall assembly 1199 which has a second end
1199b disposed proximate the first insulating sheath 1170 second
end 1171a. A second end cap 1182 may be provided proximate the
heating unit wall assembly second end 1199b. An air intake manifold
1191 may be provided upstream of the second end cap 1182. The first
thermal insulating layer 1161 and the heating chamber and the first
insulating sheath 1171 may be disposed between the first and second
end caps 1181, 1182. The CCHU 1103 may be formed from the
components disposed between and, including, the first and second
end caps 181, 182 where an airflow channel may be formed from the
upstream air intake manifold 1191 to the downstream open upper end
or side 1106d of the first heating chamber 1106. A first end cap
spacer 1183 may be provide to coupled proximate the first end cap
1181 and outside walls of the first heating chamber 1106. This
first end cap spacer 1183 may be disposed to coupled with the
outside walls of the first heating chamber 1106 and may be made
from a high temperature polymer, such as PAI for contacting the
first heating chamber 1106.
[0140] The CCHU 1103 may include the first heating element assembly
1112 that is capable of heating phyto material disposed within the
first heating chamber 1106 through conductive heating and the
thermal radiator 1806 for generating of a hot airflow as the second
source of heat that may be guided through the contents of the heat
the chamber cavity 1120. The thermal radiator 1806 may be thermally
conductively insulated from the floor of the heating chamber and
the floor of the heating chamber may be thermally convectively
coupled with the thermal radiator 1806. Heat radiating from the
thermal radiator 1806 may heat the base of the heating chamber. The
thermal radiator 1806 may provide of radiant heat to the heat the
downstream chamber cavity 1120 for aerosol generated from the
material for vaporization to be emitted from the mouthpiece 1104
which is downstream that includes an air cooling assembly (not
shown) and out through an inhalation aperture 1130 when the
mouthpiece 1104 is coupled with the device body 1102. The thermal
radiator 1806 may include a plurality of air channels 1806c and may
include a plurality of fins 1806d that may create an increased
surface area that facilitates transfer of thermal energy from the
thermal radiator to surrounding air flowing past the thermal
radiator 1806 from the air intake manifold 1191 through pores in
the third sidewall 1108c.
[0141] In accordance with this embodiment, the chamber cavity 1120
and the material for vaporization 419 is heated in two means. It
may be first heated by the first heating element assembly 1112 and
this increases a temperature of the material for vaporization 419
through conduction heating as well as some radiation heating from
the first heating element assembly 1112. This heating process may
serve to dry some of the material for vaporization to evaporate at
least some moisture from the material for vaporization 419. The
thermal radiator 1806 is subsequently enabled to provide of a hot
air stream to pass through material for vaporization 419 to heat it
through convection heating. As shown in FIG. 3B, for example a
first portion of the material for vaporization 419a may be heated
through convective heating using the thermal radiator 806 from the
second source of heat and with hot air propagating through the
material and a second portion of the material for vaporization 419b
proximate inner walls of the heating chamber may be heated through
conduction and radiation heating as the first source of heat.
[0142] The heating chamber may have a diameter or a width
approximately equal to its height and for example has a diameter of
about 11.5 mm and a height of about 12 mm and has a volume of about
1.5 cubic centimeters. The thermal radiator may be fabricated from
a metal, such as aluminum or copper. The first insulating sheath
1171 may be made from a ceramic or a high temperature plastic, such
as Torlon.RTM. or PEEK.RTM.. The heating unit wall assembly 1199
may be made from a lower temperature thermoplastic, such as ABS or
polypropylene or polycarbonate. The first and second end caps 181
and 182 may be made from a high temperature silicone. The thermal
radiator 1806 may include a ceramic heater that provides heat to
the plurality of fins 1806d.
[0143] Referring to FIGS. 3C, 3E, a cutaway view of the CCHU 1103
is shown where then the thermal radiator 1806 is in the form of a
heatsink type structure with metal fins 1826 and the second heating
element assembly 1816 is in the form of a ceramic rod heater 836
such as a MCH heating rod that may have at least two pins for
electrical current as well as may have a third electrical pin for
having an integrated temperature sensor integrated therewith. Air
coming from the air intake manifold may propagate past the heatsink
with metal fins 1826 and the air becomes convectively heater as
heat radiates from the fins int
