FIELD OF THE INVENTION
[0002] Aspects of the present invention relate to portable
electronic vaporizing devices for use with vaporizable
products.
BACKGROUND
[0003] Electronic vaporizers are common place and are generally
utilized for the purpose of aroma and/or inhalation therapy. In
this regard, vaporizers heat a substance, herbs for example, such
as tobacco, cannabis, lavender, chamomile, and many other types of
plant material. The vaporizer may work by heating the substance
through the use of direct heat or the use of hot air. There are
three common ways of heating the substance. The first is thermal
conduction where the substance is set directly on a heating element
such as a ceramic or metal plate. The second is thermal radiation
in which light is used to heat the substance. The third is
convection where hot air is passed over the substance.
[0004] At lower levels of heat, vapors extracted from substances
such as vegetable materials are mainly aroma therapeutic (inactive
fragrance) and do not usually contain the active ingredients of the
substance. Without the active ingredients being present, there is
no physiological reaction. At higher levels of heat, active
ingredients will be increasingly included in the vapor given off
during heating. Usually, aromatic vapors have already been released
and are not always present at the higher heat levels. With some
substances, such as cannabis, active ingredients appear at
different levels of heat.
[0005] After the substance is heated a mist or vapor containing
some aspect of the substance is released and either enjoyed as an
aromatic or inhaled to obtain a physiological reaction. The warm
air containing the substance product can be harsh on the throat and
bronchial tubes. Accordingly, some vaporizers use a cooling down
process that allows water moisture to be included in the vapor
produced. These vaporizers enable the user to inhale a cool moist
vapor that is relatively less harsh and irritating. Vaporizers are
often preferred over traditional methods of heating or smoking
substances due to the reduction of harsh side effects. Some of
these side effects include inhalation of tar, carbon monoxide, and
other carcinogens either directly or from second hand smoke. With
many states imposing smoking bans in public areas, vaporizers have
become popular substitutes.
[0006] Accordingly, there is a need for improved vaporizers that
provide an enhanced vaporizing experience, including vaporizers
with improved quality of the vapor produced for inhalation and
improved ease of use.
SUMMARY
[0007] Aspects of the invention are directed to a portable
electronic vaporizing device comprising:
[0008] a base having comprising a gas flow path conduit therein,
the gas flow path conduit comprising a conduit inlet and a conduit
outlet;
[0009] a mouthpiece that is removably attachable to the base, the
mouthpiece comprising: [0010] a mouthpiece housing comprising one
or more mouthpiece walls at least partly defining a mouthpiece
internal flow path through the mouthpiece housing; [0011] an
inhalation outlet formed in a region of the one or more mouthpiece
walls; and [0012] at least one mouthpiece inlet capable of being
placed in communication with the conduit outlet of the base upon
attachment of the mouthpiece to the base, to receive a flow of gas
into the mouthpiece from the base; and
[0013] an atomizer that is removably attachable to the base, the
atomizer comprising: [0014] an atomizer inlet configured to receive
a flow of gas into the atomizer; [0015] an atomizer housing
comprising one or more atomizer housing walls that at least
partially define an atomizer internal flow path therein, [0016] a
container within the atomizer housing that is capable of holding a
vaporizable product, [0017] a heating element capable of heating
the vaporizable product held in the container, [0018] a first
container inlet capable of introducing gas into the container to
entrain vaporizable product; [0019] one or more second container
outlets capable of flowing the gas having the vaporizable product
entrained therein into atomizer internal flow path; [0020] one or
more atomizer outlets capable of receiving the flows of gas from
the atomizer internal flow path, and providing the flow of gas to
the conduit inlet of the base,
[0021] wherein the flow of gas having the vaporizable product
entrained therein flows from the atomizer internal flow path and
through the gas flow conduit inlet of the base to the mouthpiece
inlet, and along the mouthpiece internal flow path to the
inhalation outlet.

DETAILED DESCRIPTION OF THE INVENTION
[0031] Aspects of the invention as described herein are directed to
an improved portable electronic vaporizing device for the
inhalation of vaporizable substances, such as aromatic substances,
therapeutic substances and/or substances with physiological
effects. Examples of such substances can include herbs, such as
tobacco, cannabis, lavender, chamomile, and other types of plant
material. In one embodiment, a vaporizable substance can comprise a
cannabinoid, such as for example one or more of cannabadiol (a
generally non-psychoactive therapeutic substance) and
tetrahydrocannabinol (THC) (a psychoactive therapeutic substance).
The vaporizable substance may in some embodiments be in the form of
an oil and/or wax product comprising the vaporizable substance,
e.g., as extracted from plant material containing the substance,
and may optionally be provided in combination with carriers or
other additives.
[0032] Referring to FIG. 1, an embodiment of a portable electronic
vaporizing device 1 is shown according to aspects of the disclosure
herein. The portable electronic device 1 comprises a base 2, and
atomizer 3 and a mouthpiece 4. The atomizer 3 is configured to
receive a vaporizable product therein and to heat the vaporizable
product to form a vapor therefrom. The mouthpiece 4 comprises an
outlet where a user can inhale the vapor produced by the atomizer,
optionally with water or other substances entrained therein. The
base 2 provides a gas flow connection between the atomizer 3 and
mouthpiece 4, to deliver the vaporized product from the atomizer 3
to the mouthpiece 4 for delivery to the use via inhalation thereof.
The base 2 can also comprise a housing for one or more components
for powering and/or controlling the device 1. For example, the base
may contain compartments therein for storing a power source, such
as a battery, for powering elements of the device 1 such as a
heating element used in the atomizer 3. In a case where the device
is powered by a rechargeable battery, such as a lithium ion
battery, the base 2 may also comprise a charging port connectable
to a battery charger (not shown). The base may also have
compartment doors to allow access to a battery or other components
held within the housing. The base 2 may also house further control
circuitry for controlling the device, such as to provide
predetermined heating cycles or heating programs, and may also
allow for user interaction with the device via control buttons
and/or control interface, a display and/or lights to signal to the
user, and/or other control and operation features.
[0033] Referring to FIG. 2, an embodiment of the device 1 is shown
in exploded view, with the mouthpiece 4 and atomizer 3 removed from
the base 2. In one embodiment, the mouthpiece 4 is removably
attachable to the base 2, for example so as to allow a user to
readily remove the mouthpiece for cleaning and/or replacement, as
is described in further detail herein. In yet another embodiment,
the atomizer may be removably attachable to the base, for example
so as to allow a user to replace the atomizer 3 when no longer
serviceable, for cleaning of the atomizer, and/or to more readily
allow access to a container (e.g. bowl) where a vaporizable product
may be loaded into the atomizer 3. In one embodiment, both the
atomizer 3 and the mouthpiece 4 may be removably attachable to the
base 2. In yet another version, the atomizer 3 may be independently
removable from the base 2. That is, the atomizer 3 may be
configured to be removably attached to the base such that it can be
removed therefrom, without requiring that the mouthpiece 2 be
removed beforehand. Referring to FIG. 2 it can be seen that the
atomizer 3 itself is external to the mouthpiece 4, and its
connection to the base 2 is also at a position that is outside the
mouthpiece 4, such that the atomizer 3 can be removed from the base
2 while the mouthpiece is kept attached to the base. Similarly,
according to the embodiment as shown, the mouthpiece 4 can be
removed from the base 2 independently of the atomizer 3, as the
mouthpiece 4 and its connection to the base are external to the
atomizer, and so the mouthpiece 4 can be removed from the base 2
without requiring removal of the atomizer 3. Furthermore, in the
embodiment as shown in FIG. 2, the atomizer 3 can be loaded with
vaporizable product without requiring removal of the mouthpiece 4,
and without requiring passing of the vaporizable product through a
portion of the mouthpiece, as the atomizer can be accessed
separately from the mouthpiece.
[0034] Referring to FIG. 3, an embodiment of a gas flow path
through the portable electronic device 1 is shown. In one
embodiment, a flow of ambient air is received in the atomizer 3,
where the ambient air is entrained with vaporizable product that is
vaporized in the atomizer via a heating element. The gas comprising
the ambient air and vaporizable product flows from the atomizer 3
to a portion of the base 2 having a gas flow conduit therein, and
which provide a sealed gas flow connection between the atomizer 3
and mouthpiece 4. The gas received into the mouthpiece 4, where it
is directed to an inhalation outlet of the mouthpiece, where the
gas comprising the vaporizable product can be inhaled by the user.
In one embodiment, water is provided a region of the mouthpiece 4
such that water is entrained with the gas passing through the
mouthpiece, thereby providing a more pleasant inhalation experience
to the user. An embodiment of an overall flow path of gas through
the device 1 is depicted via dashed lines in FIG. 3.
[0035] Referring to FIGS. 4A-4D, embodiments of the base 2, and
mechanism of attachment of the base 2 to one or more of the
atomizer 3 and mouthpiece 4 are described in more detail. As shown
in FIGS. 4A-4D, the base 2 comprises a gas flow path conduit 200
therein, the gas flow path conduit 200 comprising a conduit inlet
201a and a conduit outlet 201b, an embodiment of which may also be
viewed with respect to FIG. 5. The conduit inlet 201a receives gas
exhausted from the atomizer 3, and provides a flow of gas to the
mouthpiece 4. In one embodiment, one or more airtight seals are
formed between the base 2 and/or the atomizer 3 and mouthpiece 4,
so as to create an airtight gas flow path between from the
atomizer, through the gas flow path conduit 200 in the base 2, and
to the mouthpiece 4. In the embodiment as shown, the gas flow
conduit 200 in the base separates an atomizer internal gas flow
path from a mouthpiece internal flow path.
[0036] According to one embodiment, the atomizer 3 and/or
mouthpiece 4 are removably attachable to the base 2 via a fastening
feature 202 that allows for repeated removal and re-insertion of
the atomizer 3 and/or mouthpiece 4 into the base. In one
embodiment, the fastening feature 202 may be located on the base 2,
and/or the fastening feature 202 may be located on one or more of
the atomizer 3 and mouthpiece, and/or the components may have
mutually complementary fastening features that allow for repeatable
removal and re-attachment of the atomizer 3 and/or mouthpiece 4 to
the base 2.
[0037] In the embodiment as shown in FIGS. 4A-4D, the base 2
comprises first and second recessed regions 203a and 203b,
comprising cavities formed in the base 2 that are configured to
receive at least a portion of the atomizer 3 and mouthpiece
therein. For example, the base can comprise a first recessed region
203a configured to receive at least a portion of the atomizer 3
therein, and a second recessed region 203b configured to receive at
least a portion of the mouthpiece 4 therein. In one embodiment, the
fastening feature 202 is provided as part of the base, and can
comprise one or more airtight sealing members 204a, 204b located in
the base, such as a first airtight sealing member 204a provided in
the first recessed region to retain the atomizer therein, and/or a
second airtight sealing member 204b provided in the second recessed
region to retain the mouthpiece 4 therein. In yet another
embodiment, the fastening feature 202 may be provided on the
atomizer and/or mouthpiece. For example, the mouthpiece 4 may
comprise a snap region 401 that is configured to be received by the
second recessed region of the base, and that comprising a fastening
feature 202 thereon to retain the step region in the base, as is
described in more detail hereinbelow. In one embodiment, the
fastening feature that removably retains one or more of the
atomizer and/or mouthpiece in their respective recessed region is
also capable of providing an airtight seal between the base and
atomizer and/or mouthpiece. In another embodiment, the fastening
feature comprises a structural element that is separate from and/or
provided in addition to an airtight sealing member. For example, in
one embodiment, the base and atomizer and/or mouthpiece may be
fastened together by a fastening feature that does not provide an
airtight seal, but an airtight sealing member may be provided about
the gas flow interfaces of the base, such as about one or more of
the base conduit inlet 201a and conduit outlet 201b, to provide an
airtight connection for gas flowing from the atomizer through the
base conduit and into the mouthpiece 4. According to yet another
embodiment, the device comprises both fastening elements that
provide an airtight seal, as well as further airtight sealing
members along the gas flow path to ensure an airtight airflow. For
example, referring to FIG. 4B, an airtight sealing member 204c can
be provided about the gas conduit outlet 201b to provide an
airtight connection to the mouthpiece inlet.
[0038] In one embodiment, the base 2 is capable of forming a first
airtight compartment 205a via airtight seal with the atomizer,
and/or is capable of forming a second airtight compartment 205b via
an airtight seal with the mouthpiece 4, as shown in FIG. 5. In one
embodiment, the base comprises a first recessed receiving region
203a formed therein that is configured to receive the atomizer 3,

annular sealing region. In yet another embodiment, the second
recessed receiving region further comprises the annular sealing
region 204c about the conduit outlet 201b to form an airtight seal
between the conduit outlet 204c and a mouthpiece inlet 402. In one
embodiment, the gas flow path conduit outlet 201b in the base is
located below the annular sealing region 204b in the second
recessed region, such that an interface between the gas flow path
conduit outlet in the base, and the mouthpiece inlet is located in
an airtight compartment portion of the second recessed receiving
region. In one embodiment, the annular sealing region 204b, 204c
comprises at least one of a rubber, elastomeric, and a silicone
material. In yet another embodiment, the second recessed region is
sized an shaped to accommodate a snap region 401 of the mouthpiece
that comprises an annular indentation 403 formed about a
circumference of the mouthpiece towards a bottom end 404 of the
mouthpiece that is distal to an inhalation outlet 406 of the
mouthpiece, the annular indentation being configured to conformally
mate with the annular sealing member in the second recessed region
to so as to form the airtight compartment.
[0041] As described above, in one embodiment the base 2 comprises a
housing 209 that is configured to house a power source 210 for
powering a heating element in the atomizer 2, and optionally
comprises one or more control elements for operating components of
the device 1. For example, in one embodiment the power source 210
can comprise a rechargeable battery, such as a lithium-ion battery.
The housing may also contain outlets to connect the device with an
electrical outlet and/or other devices, and may house control
elements such a CPUs and/or wireless transmitters for controlling
heating and vapor production with the device, either via direct or
wireless input into the device by a user.
[0042] Referring to FIGS. 6A-6C and 7-11, an embodiment of an
atomizer 3 is described. In the embodiment as shown, the atomizer 3
is removably attachable to the base, an includes an atomizer inlet
301 configured to receive a flow of gas into the atomizer 3, and an
atomizer housing 10 comprising one or more atomizer housing walls
304 that at least partially define an atomizer internal flow path
therein. The atomizer 2 is further configured to contain a
container 7 (e.g., a bowl) within the atomizer housing 302 that is
capable of holding a vaporizable product therein. The atomizer
further comprises a heating element 8 capable of heating the
vaporizable product held in the container 7. According to the
embodiment as showing, the atomizer comprises a first container
inlet 305 capable of introducing gas into the container 7 to
entrain vaporizable product therein, and comprises one or more
second container outlets 306 capable of flowing the gas having the
vaporizable product entrained therein into an atomizer internal
flow path 308. Embodiments of the atomizer 3 comprise one or more
atomizer outlets 309 capable of receiving the flow of gas from the
atomizer internal flow path 308, and providing the flow of gas to
the conduit inlet 201a of the base 2.
[0043] According to one embodiment, the at least one heating
element 8 is disposed within the atomizer housing 10. For example,
the at least one heating element 8 may be disposed below a bottom
surface 310 of the container 7 that is adapted to receive the
vaporizable product therein. In one embodiment, the heating element
comprises a ceramic heating plate, such as an alumina plate. The
heating element 8 may be capable of resistively heating the
container 7 via thermal contact therewith, as in direct contact
with the bottom surface 310. In one embodiment, the heating element
8 is attached to conductive elements such as wires leading to the
power source (e.g. battery) to provide an applied voltage for the
resistive heating. In one embodiment, the container 7 adapted to
receive and hold the vaporizable product comprises a thermally
conductive ceramic material, such as alumina, such that placing the
container is in thermal contact with the heating element causes
heating of the container.
[0044] According to yet another embodiment, the atomizer 3
comprises a bottom insulating element 9 comprising a spacer
disposed between the heating element 8 and atomizer housing 10 that
thermally insulates the heating element 8 from the atomizer housing
8. The bottom insulating element 9 may also act to secure the
heating element in position at a bottom end 312 of the container,
such as in contact with the bottom surface of the container 7. In
one embodiment, the bottom insulating element comprises a ceramic
having a lower thermal conductivity than the container and/or
heating element, so as to thermally isolate the container and/or
heating element from the atomizer housing. For example, in one
embodiment the bottom insulating element can comprise a thermal
conductivity of less than 4 W/mk, less than 3.5 W/mk and/or less
than 3 W/mk, whereas the container and/or heating element may
comprise a thermal conductivity of at least 10 W/mk, at least 15
w/mk and/or at least 20 W/mk.
[0045] According to another embodiment, the atomizer 3 comprise a
top insulating element 311 that thermally insulates a top end 313
of the container 7 from the atomizer housing 10. In one embodiment,
the top insulating element 311 is configured to receive a carb cap
17 thereon. For example in one embodiment, the device 1 is
configured to operate with a carb cap 17 positioned upstream of the
atomizer 3, the carb cap comprising a stopper having a conduit 314
formed therein to provide a flow of ambient air into the atomizer
3. In one embodiment, the container 7 is thermally insulated from
the atomizer housing 10 by both the bottom insulating element 9
that positions the container within the housing at a bottom end of
the container, and the top insulating element 311 that positions a
top end of the container in the housing. In one embodiment,
referring to FIG. 6C, the top insulating element 311 comprises
inner and outer annular insulating rings 5, 6. In one embodiment,
an inner circumference of the inner annular insulating 5 ring
defines the atomizer inlet 301, and is in communication with the
first inlet 305 of the container 7. In the embodiment as shown in
FIG. 6A, the atomizer inlet 301 is directly above the first inlet
305, and/or the atomizer inlet 301 and first container inlet may
comprise the same inlet. That is, in one embodiment, the atomizer
inlet may be aligned with and lead to a container inlet positioned
below the inner annular ring 5 of the top insulating element
311.
[0046] In one embodiment, the atomizer 3 comprises an outer annular
ring 6 that forms an annular jacket that is flush with the outer
surface of the inner annular ring 5, and extends in an axial
direction beyond the inner annular ring such that a portion of the
interior surface of the outer annular ring is in contact with an
outer surface of the atomizer housing 10. In one embodiment, the
outer annular ring 6 may secure the inner annular ring 5 to the
atomizer housing 10 via frictional forces and/or via a snap
mechanism or other fastening mechanism between a portion of the
interior surface of the outer annular ring and the outer surface of
the atomizer housing. In one embodiment, the outer annular ring
comprises an annular jacket that forms an airtight seal with the
atomizer housing.
[0047] In one embodiment, one or more of the inner and outer
annular rings 5, 6 are capable of thermally isolating the container
7 from the atomizer housing 10, by having a lower thermal
conductivity. For example, one or more of the inner and outer
annular insulating rings can comprise a thermal conductivity of
less than 4 W/mk, less than 3.5 W/mk and/or less than 3 W/mk,
whereas the container may comprise a thermal conductivity of at
least 10 W/mk, at least 15 w/mk and/or at least 20 W/mk. IN one
embodiment, a bottom surface 315 of the inner annular insulating
ring 5 is in contact with an upper surface 316 of the container
7.
[0048] In one embodiment, one or more of the container 7 and/or
thermally insulating element 311, such as the inner annular ring 5,
comprise one or more apertures 318 therein that correspond to the
one or more container second outlets 306. For example, in one
embodiment the inner annular ring 5 comprises one or more
indentations 320 formed in the bottom surface 315 thereof, such as
about a circumference thereof, which form one or more apertures 318
between the bottom surface 315 of the inner annular ring 5 and the
top surface 316 of the container 7. In yet another embodiment, the
inner annular ring 5 comprises one or more apertures formed in the
body thereof, such as about a circumference thereof, to provide the
one or more container outlets. In yet another embodiment, the
container itself comprises one or more apertures 318 formed in one
or more walls thereof, wherein the one or more apertures comprise
the one or more second container outlets 306. According to certain
embodiments, first container inlet 305 introduces a gas flow
received through the inner insulating annular ring 5 into the
container 7, and the one or more second container outlets 306 flow
gas out of the container through the one or more apertures 318. The
second container outlets 306 may thus be a separate aperture and/or
opening than the first container inlet 305, such that air comes
through the inlet and passes through a separate outlet when exiting
the container 7.
[0049] Furthermore, in one embodiment, the top insulating element
311 is removable from the atomizer housing 10 to allow access to
the container 7. For example, the insulating element 311 may be
removable by simply lifting or twisting the top insulating element
form the atomizer housing 10. According to yet another embodiment,
the atomizer housing 10 comprises a lower portion 322 that is
threaded, and that may be complementary to a threaded socket in the
first recessed region 203a of the base 2, so the atomizer can be
screwed into the threaded socket of the base. In yet another
embodiment a lower portion of the atomizer housing may connects to
the base via a magnet, span mechanism or other fastening
feature.
[0050] According to one embodiment, atomizer housing at least
partially directs gas from the one or more second container gas
outlets 306 along the internal atomizer gas flow path 308 (shown as
a dashed line in FIG. 6B), in a passage 324 formed between walls of
the container 7 and the atomizer housing 10. The atomizer housing
10 can comprises one or more apertures/outlets 309 formed therein
to flow gas from the internal atomizer gas flow path 308 to the
airtight passage 207 that is external to the atomizer housing in
the first recessed region 203a of the base 2. In one embodiment,
the atomizer housing apertures/outlets 309 are located at a lower
end of the atomizer housing, and the atomizer housing 10 redirects
flow of the gas from the one or more second container gas outlets
306 in a downward direction along a passage 324 formed between the
housing walls and container walls, to the atomizer housing
apertures/outlets 309. As shown in FIG. 6B, in one embodiment a
flow of gas through the atomizer 8 comprises a flow through the
first container inlet into a top of the container, flow out of the
container through second container outlets that are separate from
the inlet, and that are towards a top 313 of the container, flow
downward between the atomizer housing and container wall towards a
bottom of the atomizer and through apertures of the atomizer
towards the bottom of the atomizer housing.
[0051] In one embodiment, the one or more second container outlets
306 are located radially externally to the first container inlet
305, and/or are positioned in an arrangement circumferentially
surrounding the first container inlet 305. The second container
outlets 306 may also be located towards a top end of the atomizer
and/or container. In a further embodiment, the apertures and/or
outlets 309 for exhausting gas from the atomizer are located below
the first container inlet and/or second container outlet, towards a
lower end of the atomizer.
[0052] Further embodiments of the atomizer are described herein.
For example, in one embodiment, inside the atomizer housing 10, a
container comprising a bowl 7 is positioned on top of the heating
element 8, and may be made of a highly thermally conductive
material, which can include ceramic, quartz, or metals, allowing
efficient heat transfer. The heating element 8 and the bowl 7 are
secured and insulated by the bottom insulating element 9 and top
insulating element 311 respectively, these two elements firmly
locating the heating element 8 and bowl 7 within the atomizer.
These two elements are made with low thermally conductive, yet high
heat withstanding, material so that minimal heat is lost from the
heating element and bowl. The top insulating element comprises an
outer annular ring comprising sleeve 6, made of an insulating
material, like silicone or plastic. The sleeve 6 fastens to the
housing 10 and makes an airtight seal while the inner annular ring
5 insulates and positions the bowl 7. The sleeve 6 may also protect
the user from heat and serves as a grip for screwing and unscrewing
the atomizer.
[0053] After extended use the bowl 7 may become dirty. Because the
top insulating element comprising in inner annular ring 5 and
sleeve (6) are removable, the bowl can be taken out and easily
cleaned. When the sleeve and top insulating element are assembled
on the atomizer housing the bowl is held in place and a sealed
airpath is formed. Air may enter the top of the bowl through a carb
cap 17. The carb cap 17 may be capable of directing high velocity
air to the bottom of the bowl, where the material is vaporized. Air
then exits the top of the bowl as vapor through the second outlets
which are apertures in the inner annular ring (5) above the bowl.
These slots/apertures could also be cut into the top of the bowl.
The vapor travels through the slots in the inner annular ring and
down a gap formed between the bowl and the atomizer housing. The
vapor can leaves the bottom of the atomizer and travels through an
airpath into the mouthpiece. FIG. 6B shows a cross sectional view
of the assembled atomizer with the carb cap and illustrates the
airflow through the atomizer, entering through the carb cap and
exiting out of the bottom of the atomizer.
[0054] In certain embodiments, material that leaks out of the bowl
7 can seep down into the bottom of the atomizer near the connection
point. Accordingly, it may be important for this area to be sealed
so that the leaking material does not inhibit the passing of the
current from power source to heating element. This seal is provided
by the electrode insulator 11 which holds the electrode 12. The
electrode insulator secures and holds separately the electrode from
the housing. One lead wire of heating element 8 can be held between
the insulator and the housing 10, the other lead wire can be held
between the insulator and the electrode, therefore a current path
in and out of the heating element can be created. There can be also
grooves cut into the atomizer housing to position these lead wires.
The electrode insulator can press the wires into these grooves and
make a water and airtight seal against the housing and electrode
which may prevents leaking. In certain embodiments, material may
also leak out of the bottom of the atomizer through the air cuts in
the housing 10. Accordingly, it may be important that this material
does not reach the connection point on the atomizer or the power
source. When the atomizer is connected to the base, a rib 14
running around the bottom of the atomizer housing 10 can create a
seal. This seal can create a separation between the air holes and
connection point and may prevent any material from reaching the
electrical connection points on the atomizer or base.
[0055] Furthermore, because the bowl 7, heating element 8 and inner
annular ring 5 may interact with sticky material during use, there
is a chance for them to become stuck together. In certain
embodiments, if the bowl is twisted during use, for example while
the user is tightening or untightening the atomizer by gripping the
sleeve, the heating element could be twisted and could lead to
subsequent breaking of its lead wires. Accordingly, features may be
included in the atomizer housing 10 and inner annular ring 5. For
example, slots in the atomizer housing 10 may line up with embossed
features 16 in the inner annular ring 5, so that the two lock
together and cannot be twisted independently. This protects the
heating element from damage when tightening or loosening the
atomizer from the base.
[0056] In one embodiment, the bowl itself can include a rib 15
around its bottom face, which is the face that interacts with the
heating element. This rib may have three functions, it can
positions the bowl, cover the heating element, and/or minimize heat
loss, and it can shroud the heating element from debris. The debris
could be water or liquid material that leaks down into the heating
elements environment. Since the heating element may operate at a
high temperature, a substance of room temperature contacting the
heating element can result in significant thermal shock which could
damage or permanently break the heating element. The rib on the
bottom of the bowl blocks debris by creating a protective wall
around the heating element.
[0057] Referring to FIGS. 1-3, 5 and 12, embodiments of the
mouthpiece 4 are further described. In one embodiment, the
mouthpiece 4 is removably attachable to the base 2. The mouthpiece
can generally comprise a mouthpiece housing 408, comprising one or
more mouthpiece walls 410 at least partly defining a mouthpiece
internal flow path 412 through the mouthpiece housing (e.g., as
shown in FIG. 3). The mouthpiece can further comprises the
inhalation outlet 406 formed in a region of the one or more
mouthpiece walls 410, such as towards a top end 405 of the
mouthpiece 4. The mouthpiece can further comprise at least one
mouthpiece inlet 402 capable of being placed in communication with
the conduit outlet 201b of the base 2 upon attachment of the
mouthpiece 4 to the base 2, to receive a flow of gas into the
mouthpiece 4 from the base 2. In some embodiments a gas flowed
through the mouthpiece from the mouthpiece inlet 402 to the
inhalation outlet 406, may take a convoluted path through the
interior volume of the mouthpiece and along the internal flow path,
such as for example when a water filtering region is provided as
part of the mouthpiece.
[0058] In one embodiment, the mouthpiece comprises a snap region
401 that is configured to removably attach the mouthpiece to the
base. For example, in one embodiment, the base can comprises the
second recessed receiving region 203b for receiving the mouthpiece
therein via the snap region 401, which may be shaped and sized to
fit within the second recesses receiving region. The snap region
401 may be located at the bottom end 404 of the mouthpiece, and in
certain embodiments the mouthpiece inlet 402 may located in the
snap region 401, of the mouthpiece. In one embodiment, the second
receiving region 403b may be at least partially lined with a
rubber, silicone, and/or elastomeric sleeve to conformally mate the
second recessed region with the snap region of the mouthpiece. In
yet another embodiment, at least a portion of the snap region of
the mouthpiece may be lined with a rubber, silicone, and/or
elastomeric sleeve to conformally mate the second recessed region
with the snap region of the mouthpiece. As yet another example, in
one embodiment, the sleeve 208 comprises an annular sealing region
204b that protrudes inwardly from sidewalls of the second recessed
region to contact and form an airtight seal with the
mouthpiece.
[0059] In yet another embodiment, the mouthpiece comprises one or
more water filtering regions 414a, 414b, capable of holding a
volume of water therein, the water filtering region being located
along the mouthpiece internal flow path, such that water vapor
becomes entrained into gas passing through water in the water
filtering region. In the embodiment as shown in FIG. 3, a volume of
water can be provided to partly fill in internal volume of the
mouthpiece volume along a lower region of the internal mouthpiece
volume.
[0060] In one embodiment, the at least one mouthpiece inlet 402 is
located towards a bottom region 404 of the mouthpiece housing 408,
and the inhalation outlet 406 is located distal to the at least one
mouthpiece inlet 402 at an upper region 405 of the mouthpiece
housing. According to yet another embodiment, the mouthpiece 4
comprises a plurality of chambers 416a, 416b that are connected to
one another along the mouthpiece internal flow path 412. For
example, the mouthpiece can comprise a first chamber 416a that is
internal to a second chamber 416b, and wherein a flow of gas along
the mouthpiece internal flow path 412 passes through the first
chamber and into the second chamber. In one embodiment, the second
chamber at least partially circumferentially surrounds the first
chamber. In one embodiment, the mouthpiece comprises one or more
internal walls 418 defining the first chamber 416a, and wherein the
second chamber 416b is defined between the one or more internal
walls 418 and the mouthpiece housing 408. In one embodiment, lower
portions of the first and second chambers 416a, 416b comprise water
filtering regions configured to receive and hold water therein.
Furthermore, in one embodiment, the first and second chamber are
connected to each other by at least one port 420 formed in the one
or more internal walls 418.
[0061] In the embodiment as shown in FIG. 3, the first chamber 416a
comprises a first chamber inlet 422 that is positioned above the at
least one port 420 formed in the one or more internal walls, which
port may be located at or below a level of water in the chambers
when water is provided in the mouthpiece. In one embodiment, a flow
of gas exiting the first chamber inlet 422 is directed by the one
or more internal walls 418 towards the water filtering region in a
lower portion of the first chamber 416a, and the gas exits the
water filtering region in the lower portion of the first chamber
416a through the one or more ports 420 to enter a water filtering
region of a lower portion of the second chamber 461b, and wherein
gas having water vapor therein exits the water filtering region of
the lower portion of the second chamber and is directed by the
passage formed between the housing walls 410 and internal walls 418
to be output from the mouthpiece via the inhalation outlet. In the
embodiment as shown in FIG. 3, the first chamber inlet 422 is at
the end of a tube 424 extending upwardly into the first chamber
416a, the tube comprising an aperture to receive gas from the
mouthpiece inlet, and wherein the first chamber inlet is located at
a location that is higher than the port connecting the chambers. In
another embodiment, the one or more internal walls 481 comprise a
conically-shaped internal wall, and the mouthpiece housing
comprises a conical housing wall about the conically-shaped
internal wall.
[0062] In one embodiment, the mouthpiece 4 comprises a snap region
401 with one or more fastening features 202 on an external surface
426 thereof to fasten the snap region to the recessed region 203b
of the base 2. In one embodiment, the fastening feature 202 may
provide a sealing fit between the snap region and the recessed
region when the snap region is inserted into the recessed region.
In one embodiment, the fastening features may be able to removably
fasten the mouthpiece to the base such that mouthpiece can
withstand at least 2 lbs, at least 3 lbs and/or at least 5 lbs of
vertical force before the snap region of the mouthpiece releases
from the recessed region of the base.
[0063] In yet another embodiment, the at least one mouthpiece inlet
402 may direct gas into the mouthpiece in a direction that is not
co-linear with and/or that is other than a direction that gas exits
the mouthpiece via the inhalation outlet 406. For example, the at
least one mouthpiece inlet may direct gas into the mouthpiece in a
direction that is substantially perpendicular to a direction that
gas exits the mouthpiece via the inhalation outlet.
[0064] In one embodiment, the at least a portion of the mouthpiece
housing, and even the entire mouthpiece housing, may be formed of
glass. In one embodiment, the snap region 401 of the mouthpiece may
also be formed of glass. Internal structures such as internal walls
between compartments, and tubes for introduction of gas, may also
be formed of glass. In one embodiment, the snap region 401 of the
mouthpiece comprise a greatest diameter D.sub.1 (the largest
diameter along the height of the snap region, see e.g. FIG. 12)
that is at least 20 mm, at least 30 mm, and/or at least 50. In some
embodiments, the snap region 401 may be considered to be that
portion of the mouthpiece that is received by the recessed region
of the base. As shown in FIG. 12, a body region 428 that is clear
of the recessed region when the mouthpiece is connected to the
base, may in some embodiments have a diameter that exceeds that of
the snap region 401 that fits within the base. Furthermore, in one
embodiment an internal volume of the mouthpiece 4 is configured to
accept at least 1 fluid ounces of water therein during operation a
device comprising the mouthpiece.
[0065] In one embodiment, referring to FIG. 12, the snap region 401
of the mouthpiece can comprises a fastening feature 202 comprising
a circumferentially bulging protrusion 430 along a height of the
snap region, where a diameter D of the protrusion 430 exceeds a
minimum diameter D.sub.2 of the recessed region of the base at some
point along the height of the region (e.g., at a point where a
sealing member 204b protrudes into the recessed region, see FIG.
4A). In certain embodiments, passing the bulging protrusion 430
past the minimum diameter D.sub.2 of the recessed region causes the
snap region to be removably retained in the recessed region. In one
embodiment, the mouthpiece further comprises a fastening feature
202 comprising an annular indentation 432 formed about a
circumference of the snap region portion of the mouthpiece. For
example, the annular indentation may be configured to conformally
mate with the circumferential sealing member 204b extending from a
sidewall of the recessed region of the base, so as to form a seal
therebetween. In one embodiment, the annular indentation can
comprise an annular groove and/or annular channel formed in the
mouthpiece housing at the snap region. In one embodiment, the
annular indention may be located above the at least one mouthpiece
gas inlet in the snap region, and/or the circumferentially bulging
protrusion may have the at least one mouthpiece inlet formed
therein. According to yet another embodiment, the fastening feature
comprises a tapering snap region profile, the snap region having a
first region adjacent the bottom of the mouthpiece housing (e.g.,
at the bulging protrusion) having a first diameter D.sub.1, and a
second region that is spaced apart from the first region (e.g. at
the annular indentation) having a second diameter D.sub.3, and
wherein the diameter of the snap region decreases from the first
region to the second region (e.g., D3 is less than D1).
[0066] In one embodiment, a method of using a portable electronic
vaporizer as described according to any of the embodiments herein,
can comprise loading vaporizable product into the container,
optionally at least partially filling the mouthpiece with water in
water filter regions thereof, activating the heating element to at
least partially vaporize the product in the container, and inhaling
gas exiting the mouthpiece inlet, the gas comprising ambient air
having vaporize product and water vapor entrained therein.
