SUMMARY
[0004] An e-vapor apparatus may include a pod assembly, a
dispensing body configured to receive the pod assembly, and/or a
vaporizer disposed in at least one of the pod assembly and the
dispensing body. The pod assembly may include a vapor precursor
compartment, a device compartment, and a vapor channel extending
from the device compartment and traversing the vapor precursor
compartment. The vapor precursor compartment is configured to hold
a vapor precursor therein. The dispensing body includes a proximal
portion and an opposing distal portion. The proximal portion
includes a vapor passage and a through-hole. The vapor passage may
extend from an end surface of the proximal portion to a side wall
of the through-hole. The through-hole may be between the vapor
passage and the distal portion of the dispensing body. The
through-hole is configured to receive the pod assembly. The
vaporizer may be disposed in at least one of the pod assembly and
the dispensing body. The vapor precursor compartment of the pod
assembly is configured to be in fluidic communication with the
vaporizer during an operation of the e-vapor apparatus such that
the vapor precursor from the vapor precursor compartment comes into
thermal contact with the vaporizer. The vaporizer is configured to
heat the vapor precursor to produce a vapor that passes through the
pod assembly via the vapor channel. The through-hole of the
dispensing body is configured to receive the pod assembly such that
the vapor channel of the pod assembly is aligned with the vapor
passage of the dispensing body so as to facilitate a delivery of
the vapor through the vapor passage of the dispensing body.
[0005] The vapor precursor compartment of the pod assembly may
surround the vapor channel. For example, the vapor channel may pass
through a center of the vapor precursor compartment.
[0006] Alternatively, the vapor channel may be in a form of a
pathway that is arranged along at least one sidewall of the vapor
precursor compartment. For example, the vapor channel may be in a
form of a conduit that is arranged in at least one corner of the
vapor precursor compartment. The conduit may be arranged in at
least two corners of the vapor precursor compartment and configured
to converge at a position that is aligned with the vapor passage of
the dispensing body when the pod assembly is received in the
through-hole.
[0007] The vapor precursor compartment and the device compartment
may be at opposite ends of the pod assembly. The device compartment
of the pod assembly may include a memory device. The memory device
may be coded with an electronic identity to permit at least one of
an authentication of the pod assembly and a pairing of operating
parameters specific to a type of the pod assembly when the pod
assembly is inserted into the through-hole of the dispensing body.
The memory device may also receive and store information such as
operational parameters and usage history from the dispensing body.
Once stored, such information in the memory device will remain
intact even when the pod is detached from the dispensing body.
[0008] The pod assembly may include a side surface having at least
one electrical contact. The dispensing body may be configured to
perform at least one of supply power to and communicate with the
pod assembly via the at least one electrical contact. The at least
one electrical contact may be at an end of the pod assembly
corresponding to the device compartment.
[0009] The dimensions of the through-hole correspond to dimensions
of the pod assembly. The proximal portion of the dispensing body
may include a mouthpiece that includes the vapor passage. The vapor
channel may be between the mouthpiece and the device compartment
when the pod assembly is inserted into the through-hole of the
dispensing body. The e-vapor apparatus may further include an
attachment structure on at least one of the side wall of the
through-hole and a side surface of the pod assembly. The attachment
structure is configured to engage and hold the pod assembly upon
insertion into the through-hole of the dispensing body. The
attachment structure enables the pod assembly to be inserted and
extracted from the dispensing body by the adult vaper with ease.
The attachment structure also aligns and secures the pod assembly
in place in the dispensing body during normal use of the e-vapor
apparatus.
[0010] A pod assembly for an e-vapor apparatus may include a vapor
precursor compartment configured to hold a vapor precursor therein;
a device compartment in fluidic communication with the vapor
precursor compartment; and a vapor channel extending from the
device compartment and traversing the vapor precursor compartment.
The device compartment may include a vaporizer. The device
compartment may also include a memory device. A side surface of the
pod assembly may include at least one electrical contact.

DETAILED DESCRIPTION
[0034] It should be understood that when an element or layer is
referred to as being "on," "connected to," "coupled to," or
"covering" another element or layer, it may be directly on,
connected to, coupled to, or covering the other element or layer or
intervening elements or layers may be present. In contrast, when an
element is referred to as being "directly on," "directly connected
to," or "directly coupled to" another element or layer, there are
no intervening elements or layers present. Like numbers refer to
like elements throughout the specification. As used herein, the
term "and/or" includes any and all combinations of one or more of
the associated listed items.
[0035] It should be understood that, although the terms first,
second, third, etc. may be used herein to describe various
elements, components, regions, layers and/or sections, these
elements, components, regions, layers, and/or sections should not
be limited by these terms. These terms are only used to distinguish
one element, component, region, layer, or section from another
region, layer, or section. Thus, a first element, component,
region, layer, or section discussed below could be termed a second
element, component, region, layer, or section without departing
from the teachings of example embodiments.
[0036] Spatially relative terms (e.g., "beneath," "below," "lower,"
"above," "upper," and the like) may be used herein for ease of
description to describe one element or feature's relationship to
another element(s) or feature(s) as illustrated in the figures. It
should be understood that the spatially relative terms are intended
to encompass different orientations of the device in use or
operation in addition to the orientation depicted in the figures.
For example, if the device in the figures is turned over, elements
described as "below" or "beneath" other elements or features would
then be oriented "above" the other elements or features. Thus, the
term "below" may encompass both an orientation of above and below.
The device may be otherwise oriented (rotated 90 degrees or at
other orientations) and the spatially relative descriptors used
herein interpreted accordingly.
[0037] The terminology used herein is for the purpose of describing
various embodiments only and is not intended to be limiting of
example embodiments. As used herein, the singular forms "a," "an,"
and "the" are intended to include the plural forms as well, unless
the context clearly indicates otherwise. It will be further
understood that the terms "includes," "including," "comprises,"
and/or "comprising," when used in this specification, specify the
presence of stated features, integers, steps, operations, elements,
and/or components, but do not preclude the presence or addition of
one or more other features, integers, steps, operations, elements,
components, and/or groups thereof.
[0038] Example embodiments are described herein with reference to
cross-sectional illustrations that are schematic illustrations of
idealized embodiments (and intermediate structures) of example
embodiments. As such, variations from the shapes of the
illustrations as a result, for example, of manufacturing techniques
and/or tolerances, are to be expected. Thus, example embodiments
should not be construed as limited to the shapes of regions
illustrated herein but are to include deviations in shapes that
result, for example, from manufacturing. The regions illustrated in
the figures are schematic in nature and their shapes are not
intended to illustrate the actual shape of a region of a device and
are not intended to limit the scope of example embodiments.
[0039] Unless otherwise defined, all terms (including technical and
scientific terms) used herein have the same meaning as commonly
understood by one of ordinary skill in the art to which example
embodiments belong. It will be further understood that terms,
including those defined in commonly used dictionaries, should be
interpreted as having a meaning that is consistent with their
meaning in the context of the relevant art and will not be
interpreted in an idealized or overly formal sense unless expressly
so defined herein.
[0040] FIG. 1 is a perspective view of a dispensing body of an
e-vapor apparatus according to an example embodiment. Referring to
FIG. 1, a dispensing body 104 of an e-vapor apparatus includes a
frame portion that is connected to a body portion 118. The frame
portion includes a first frame 110 and a second frame 112. The side
walls 116 (e.g., inner side surfaces) of the first frame 110 and
the second frame 112 define a through-hole 114. The through-hole
114 is configured to receive a pod assembly (which will be
subsequently discussed in detail).
[0041] Generally, an e-vapor apparatus may include the dispensing
body 104, a pod assembly inserted in the through-hole 114 of the
dispensing body 104, and a vaporizer disposed in at least one of
the pod assembly and the dispensing body 104. The pod assembly may
include a vapor precursor compartment (e.g., liquid compartment), a
device compartment, and a vapor channel. The vapor channel may
extend from the device compartment and traverse the vapor precursor
compartment. The vapor precursor compartment is configured to hold
a vapor precursor (e.g., e-liquid) therein. A vapor precursor is a
material or combination of materials that may be transformed into a
vapor. For example, the vapor precursor may be a liquid, solid,
and/or gel formulation including, but not limited to, water, beads,
solvents, active ingredients, ethanol, plant extracts, natural or
artificial flavors, and/or vapor formers such as glycerine and
propylene glycol.
[0042] The dispensing body 104 includes a proximal portion and an
opposing distal portion. The mouthpiece 108 is disposed at the
proximal portion, while the end piece 120 is disposed at the distal
portion. The proximal portion includes a vapor passage 106 and the
through-hole 114. The vapor passage 106 extends from an end surface
of the proximal portion to the side wall 116 of the through-hole
114. The vapor passage 106 is in the form of one or more
passageways extending through the proximal portion of the
dispensing body 104. The through-hole 114 is between the vapor
passage 106 and the distal portion of the dispensing body 104
(e.g., between the mouthpiece 108 and the body portion 118).
[0043] A vaporizer (which will be subsequently discussed in more
detail) is disposed in at least one of the pod assembly and the
dispensing body 104. The vapor precursor compartment of the pod
assembly is configured to be in fluidic communication with the
vaporizer during an operation of the e-vapor apparatus such that
the vapor precursor from the vapor precursor compartment comes into
thermal contact with the vaporizer. The vaporizer is configured to
heat the vapor precursor to produce a vapor that passes through the
pod assembly via the vapor channel. The through-hole 114 of the
dispensing body 104 is configured to receive the pod assembly such
that the vapor channel of the pod assembly is aligned with the
vapor passage 106 of the dispensing body 104 so as to facilitate a
delivery of the vapor through the vapor passage 106 of the
dispensing body 104.
[0044] FIG. 2 is an exploded view of the dispensing body of FIG. 1.
Referring to FIG. 2, the first frame 110 and the second frame 112
are configured to unite to form the frame portion of the dispensing
body 104. A number of options are available for uniting the first
frame 110 and the second frame 112. In an example embodiment, the
first frame 110 is a female member, while the second frame 112 is a
male member that is configured to engage therewith. Alternatively,
the first frame 110 may be a male member, while the second frame
112 may be a female member that is configured to engage therewith.
The engagement of the first frame 110 and the second frame 112 may
be via a snap-fit, friction-fit, or slide-lock type arrangement,
although example embodiments are not limited thereto.
[0045] The first frame 110 may be regarded as the front frame of
the dispensing body 104, and the second frame 112 may be regarded
as the rear frame (or vice versa). Additionally, the proximal ends
of the first frame 110 and the second frame 112, when united,
define the vapor passage 106 therebetween. The vapor passage 106
may be in the form of a single passageway that is in communication
with the through-hole 114 defined by the side wall 116.
Alternatively, the vapor passage 106 may be in the form of a
plurality of passageways that are in communication with the
through-hole 114 defined by the side wall 116. In such an example,
the plurality of passageways may include a central passageway
surrounded by peripheral passageways (or just several evenly spaced
passageways). Each of the plurality of passageways may
independently extend from the through-hole 114 to the proximal end
surface of the frame portion. Alternatively, a common passageway
may extend partly from the through-hole 114 and then branch into a
plurality of passageways that extend to the proximal end surface of
the frame portion.
[0046] The mouthpiece 108 is configured to slip onto the proximal
end of the frame portion that defines the vapor passage 106. As a
result, the outer surface of the proximal end formed by the first
frame 110 and the second frame 112 may correspond to an inner
surface of the mouthpiece 108. Alternatively, the proximal end
defining the vapor passage 106 may be integrally formed as part of
the mouthpiece 108 (instead of being a part of the frame portion).
The mouthpiece 108 may be secured via a snap-fit type or other
suitable arrangement. In an example embodiment, the mouthpiece 108
is a removable component that is intended to permit voluntary,
recommended, or required replacement by an adult vaper. For
instance, the mouthpiece 108 may, in addition to its intended
functionality, provide a visual or other sensory appeal to the
adult vaper. In particular, the mouthpiece 108 may be formed of an
ornamental material (e.g., wood, metal, ceramic) and/or include
designs (e.g., patterns, images, characters). Thus, the mouthpiece
108 may be customized so as to provide an expression of personality
and individuality by an adult vaper. In other instances, the
removable nature of the mouthpiece 108 may facilitate a recommended
replacement due to the amount of usage or a required replacement
due to wear over time or damage (e.g., chipped mouthpiece 108
caused by accidental dropping of e-vapor apparatus).
[0047] The lower ends of the first frame 110 and the second frame
112 opposite the proximal ends (that define the vapor passage 106)
are configured to insert into the body portion 118. To facilitate a
secure fit, the outer surface of the lower ends of the first frame
110 and the second frame 112 may correspond to a receiving inner
surface of the body portion 118. Additionally, the lower ends of
the first frame 110 and the second frame 112 may also define a
groove therebetween to accommodate one or more wires that connect
to one or more electrical contacts provided in the side wall 116
(e.g., lower surface of the side wall 116 opposite the vapor
passage 106). A power source (e.g., battery) may also be provided
in the groove to supply the requisite current through the wire(s).
Alternatively, the power source may be provided in an available
space within the body portion 118 between the inserted lower end of
the frame portion and the end piece 120.
[0048] A first button 122 and a second button 124 may be provided
on the body portion 118 and connected to the corresponding
circuitry and electronics therein. In an example embodiment, the
first button 122 may be a power button, and the second button 124
may be a battery level indicator. The battery level indicator may
display a representation of the amount of power available (e.g., 3
out of 4 bars). In addition, the battery level indicator may also
blink and/or change colors to alert an adult vaper to recharge the
e-vapor apparatus. To stop the blinking, an adult vaper may simply
press the second button 124. Thus, the button(s) of the e-vapor
apparatus may have a control and/or display function. It should be
understood that the examples with regard to the first button 122
and the second button 124 are not intended to be limiting and can
have different implementations depending on the desired
functionalities. Accordingly, more than two buttons (and/or of
different shapes) may be provided in the same proximity or at a
different location on the e-vapor apparatus.
[0049] FIG. 3 is a perspective view of the mouthpiece of FIG. 2.
Referring to FIG. 3, the mouthpiece 108 may be an open-ended
cap-like structure that is configured to slip onto the proximal end
of the frame portion defining the vapor passage 106. The mouthpiece
108 may have a wider base that tapers to a narrower top. However,
it should be understood that example embodiments are not limited
thereto. The mouthpiece 108 may also be shaped to better
accommodate an adult vaper's mouth during inhalation of the vapor.
For instance, one side of the mouthpiece 108 may be more linear,
while the opposing side may be more curved.
[0050] FIG. 4 is a perspective view of the first frame of FIG. 2.
Referring to FIG. 4, the first frame 110 includes a side wall 116
that defines a through-hole 114. The first frame 110 is configured
to unite with the second frame 112, which also includes a side wall
116 defining a through-hole 114. Because the combined through-hole
114 is configured to receive a pod assembly, the side walls 116 of
the first frame 110 and the second frame 112 may form a relatively
smooth and continuous surface to facilitate the insertion of the
pod assembly.
[0051] FIG. 5 is a perspective view of the second frame of FIG. 2.
Referring to FIG. 5, the second frame 112 is configured to unite
with the first frame 110 such that the shape defined by the
combined side walls 116 corresponds to the shape of the side
surface of a pod assembly. In addition, an attachment structure
(e.g., mating member/recess, magnetic arrangement) may be provided
on at least one of the side walls 116 and the side surface of the
pod assembly.
[0052] For example, the attachment structure may include a mating
member that is formed on the side wall 116 (of the first frame 110
and/or second frame 112) and a corresponding recess that is formed
on the side surface of the pod assembly. Conversely, the mating
member may be formed on the side surface of the pod assembly, while
the corresponding recess may be formed on the side wall 116 (of the
first frame 110 and/or second frame 112). In a non-limiting
embodiment, the mating member may be a rounded structure to
facilitate the engagement/disengagement of the attachment
structure, while the recess may be a concave indentation that
corresponds to the curvature of the rounded structure. The mating
member may also be spring-loaded so as to retract (via spring
compression) when the pod assembly is being inserted into the
through-hole 114 and protract (via spring decompression) when
mating member becomes aligned with the corresponding recess. The
engagement of the mating member with the corresponding recess may
result in an audible click, which notifies the adult vaper that the
pod assembly is secured and properly positioned within the
through-hole 114 of the dispensing body 104.
[0053] In another example, the attachment structure may include a
magnetic arrangement. For instance, a first magnet may be arranged
in the side wall 116 (of the first frame 110 and/or second frame
112), and a second magnet may be arranged in the side surface of
the pod assembly. The first and/or second magnets may be exposed or
hidden from view behind a layer of material. The first and second
magnets are oriented so as to be attracted to each other, and a
plurality of pairs of the first and second magnets may be provided
to ensure that the pod assembly will be secure and properly aligned
within the through-hole 114 of the dispensing body 104. As a
result, when the pod assembly is inserted in the through-hole 114,
the pair(s) of magnets (e.g., first and second magnets) will be
attracted to each other and, thus, hold the pod assembly within the
through-hole 114 while properly aligning the channel outlet of the
pod assembly with the vapor passage 106 of the dispensing body
104.
[0054] FIG. 6 is a perspective view of the body portion of FIG. 2.
Referring to FIG. 6, the body portion 118 may be a tube-like
structure that constitutes a substantial segment of the dispensing
body 104. The cross-section of the body portion 118 may be
oval-shaped, although other shapes are possible depending on the
structure of the frame portion. An adult vaper may hold the e-vapor
apparatus by the body portion 118. Accordingly, the body portion
118 may be formed of (or covered with) a material that provides
enhanced gripping and/or texture appeal to the fingers
[0055] FIG. 7 is a perspective view of the end piece of FIG. 2.
Referring to FIG. 7, the end piece 120 is configured to be inserted
in the distal end of the body portion 118. The shape of the end
piece 120 may correspond to the shape of the distal end of the body
portion 118 so as to provide a relatively smooth and continuous
transition between the two surfaces.
[0056] FIG. 8 is a perspective view of another dispensing body of
an e-vapor apparatus according to an example embodiment. Referring
to FIG. 8, the dispensing body 204 includes a side wall 216
defining a through-hole 214 that is configured to receive a pod
assembly. A substantial portion of the framework of the dispensing
body 204 is provided by the first frame 210, the frame trim 211,
and the second frame 212 (e.g., FIG. 9). A vapor passage 206 and a
first mouthpiece 208 are provided at a proximal portion of the
dispensing body 204.
[0057] FIG. 9 is an exploded view of the dispensing body of FIG. 8.
Referring to FIG. 9, the frame trim 211 is sandwiched between the
first frame 210 and the second frame 212. However, it should be
understood that it is possible to modify and structure the first
frame 210 and the second frame 212 such that the frame trim 211 is
not needed. The vapor passage 206 may be defined by both the
proximal ends of the first frame 210 and the second frame 212 as
well as the second mouthpiece 209. As a result, the vapor passage
206 extends from the side wall 216 to the outlet end of the second
mouthpiece 209. The first mouthpiece 208 is configured to slip onto
the second mouthpiece 209. In an example embodiment, the first
mouthpiece 208 may be structured to be removable, while the second
mouthpiece 209 may be structured to be permanent. Alternatively,
the first mouthpiece 208 may be integrated with the second
mouthpiece 209 to form a single structure that is removable.
[0058] A first button 222, a second button 224, and a third button
226 may be provided on the second frame 212 of the dispensing body
204. In an example embodiment, the first button 222 may be a
display (e.g., battery level indicator), the second button 224 may
control an amount of vapor precursor available to the heater, and
the third button 226 may be the power button. However, it should be
understood that example embodiments are not limited thereto.
Notably, the buttons can have different implementations depending
on the desired functionalities. Accordingly, a different number of
buttons (and/or of different shapes) may be provided in the same
proximity or at a different location on the e-vapor apparatus.
Furthermore, the features and considerations in connection with the
dispensing body 104 that are also applicable to the dispensing body
204 may be as discussed supra in connection with the dispensing
body 104.
[0059] FIG. 10 is a perspective view of the first mouthpiece of
FIG. 9. Referring to FIG. 10, the first mouthpiece 208 is
configured to fit over the second mouthpiece 209. Thus, the inner
surface of the first mouthpiece 208 may correspond to an outer
surface of the second mouthpiece 209.
[0060] FIG. 11 is a perspective view of the second mouthpiece of
FIG. 9. Referring to FIG. 11, the second mouthpiece 209 defines a
vapor passage 206 therein. The second mouthpiece 209 may resemble
the combined proximal ends of the first frame 110 and the second
frame 112 that define the vapor passage 106 of the dispensing body
104.
[0061] FIG. 12 is a perspective view of the first frame of FIG. 9.
Referring to FIG. 12, the first frame 210 includes a side wall 216
that defines a through-hole 214. The top end of the first frame 210
may include a connection structure that facilitates the connection
of at least the second mouthpiece 209 thereto.
[0062] FIG. 13 is a perspective view of the frame trim of FIG. 9.
Referring to FIG. 13, the frame trim 211 may be in the form of a
curved strip that is supported by a central plate. When arranged
between the first frame 210 and the second frame 212, the frame
trim 211 forms a side surface of the dispensing body 204, although
example embodiments are not limited thereto.
[0063] FIG. 14 is a perspective view of the second frame of FIG. 9.
Referring to FIG. 14, the second frame 212 includes a side wall 216
that defines a through-hole 214. The top end of the second frame
212 may include a connection structure that facilitates the
connection of at least the second mouthpiece 209 thereto. In
addition, the surface of the second frame 212 may be provided with
a pattern or textured appearance. Such patterning and texturing may
be aesthetic (e.g., visually appealing) and/or functional (e.g.,
enhanced grip) in nature. Although not shown, the surface of the
first frame 210 may be similarly provided.
[0064] FIG. 15 is a perspective view of a pod assembly of an
e-vapor apparatus according to an example embodiment. Referring to
FIG. 15, the pod assembly 302 includes a pod trim 310 that is
arranged between a first cap 304 and a second cap 314. The first
cap 304 may be regarded as a front cap, and the second cap 314 may
be regarded as a rear cap (or vice versa). The first cap 304 and
the second cap 314 may be formed of a transparent material to
permit a viewing of the contents (e.g., vapor precursor) in the pod
assembly 302. The pod trim 310 defines a channel outlet 312 for the
release of vapor generated within the pod assembly 302.
[0065] The pod assembly 302 is a self-contained article that can be
sealed with a protective film that wraps around the pod trim 310.
Additionally, because of the closed system nature of the pod
assembly 302, the risk of tampering and contamination can be
reduced. Also, the chance of unwanted physical exposure to the
vapor precursor within the pod assembly 302 (e.g., via a leak) can
be reduced. Furthermore, the pod assembly 302 can be structured so
as to prevent refilling.
[0066] FIG. 16 is a top view of the pod assembly of FIG. 15.
Referring to FIG. 16, the second cap 314 is wider than the first
cap 304. As a result, the pod trim 310 may slant outwards from the
first cap 304 to the second cap 314. However, it should be
understood that other configurations are possible depending on the
design of the pod assembly 302.
[0067] FIG. 17 is a side view of the pod assembly of FIG. 15.
Referring to FIG. 17, the second cap 314 is longer than the first
cap 304. As a result, the pod trim 310 may slant outwards from the
first cap 304 to the second cap 314. As a result, the pod assembly
302 may be inserted in a dispensing body such that the side
corresponding to the first cap 304 is received in the through-hole
first. In an example embodiment, the pod assembly 302 may be
inserted in the through-hole 114 of the dispensing body 104 and/or
the through-hole 214 of the dispensing body 204.
[0068] FIG. 18 is an exploded view of the pod assembly of FIG. 15.
Referring to FIG. 18, the internal space of the pod assembly 302
may be divided into a plurality of compartments by virtue of the
components therein. For instance, the tapered outlet of the vapor
channel 308 may be aligned with the channel outlet 312, and the
space bounded by the first cap 304, the vapor channel 308, the pod
trim 310, and the second cap 314 may be regarded as the vapor
precursor compartment. Additionally, the bounded space under the
vapor channel 308 may be regarded as the device compartment. For
instance, the device compartment may include the vaporizer 306. One
benefit of including the vaporizer 306 in the pod assembly 302 is
that the vaporizer 306 will only be used for the amount of vapor
precursor contained within the vapor precursor compartment and,
thus, will not be overused.
[0069] FIG. 19 a perspective view of several pod assemblies
according to an example embodiment. Referring to FIG. 19, each of
the pod assemblies 402 includes a pod trim 410 arranged between a
first cap 404 and a second cap 414. The vapor channel 408 is
aligned with the channel outlet 412 and arranged above the
vaporizer 406. The pod assembly 402 is sealed to hold a vapor
precursor 418 therein and to preclude tampering therewith. The
vapor precursor compartment of the pod assembly 402 is configured
to hold the vapor precursor 418, and the device compartment
includes the vaporizer 406.
[0070] In further detail, the pod assembly 402 for an e-vapor
apparatus may include a vapor precursor compartment configured to
hold a vapor precursor 418 therein. A device compartment is in
fluidic communication with the vapor precursor compartment. The
device compartment includes a vaporizer 406. A vapor channel 408
extends from the device compartment and traverses the vapor
precursor compartment.
[0071] The pod assembly 402 is configured for insertion into a
dispensing body. As a result, the dimensions of the pod assembly
402 may correspond to the dimensions of the through-hole (e.g.,
114) of the dispensing body (e.g., 104). The vapor channel 408 may
be between the mouthpiece (e.g., 108) and the device compartment
when the pod assembly 402 is inserted into the through-hole of the
dispensing body.
[0072] An attachment structure (e.g., male/female member
arrangement, magnetic arrangement) may be provided on at least one
of the side wall (e.g., 116) of the through-hole (e.g., 114) and a
side surface of the pod assembly 402. The attachment structure may
be configured to engage and hold the pod assembly 402 upon
insertion into the through-hole of the dispensing body. In
addition, the channel outlet 412 may be utilized to secure the pod
assembly 402 within the through-hole of the dispensing body. For
instance, the dispensing body may be provided with a retractable
vapor connector that is configured to insert into the channel
outlet 412 so as to secure the pod assembly 402 while also
supplementing the vapor path from the channel outlet 412 to the
vapor passage (e.g., 106) of the dispensing body (e.g., 104). The
vapor connector may also be a rounded structure and/or
spring-loaded to facilitate its retraction (e.g., via spring
compression) and protraction (e.g., via spring decompression).
[0073] In an example embodiment, the vapor precursor compartment of
the pod assembly 402 may surround the vapor channel 408. For
instance, the vapor channel 408 may pass through a center of the
vapor precursor compartment, although example embodiments are not
limited thereto.
[0074] Alternatively, instead of the vapor channel 408 shown in
FIG. 19, a vapor channel may be in a form of a pathway that is
arranged along at least one sidewall of the precursor compartment.
For example, a vapor channel may be provided in a form of a pathway
that spans between the first cap 404 and the second cap 414 while
extending along one or both sides of an inner surface of the pod
trim 410. As a result, the pathway may have a thin, rectangular
cross-section, although example embodiments are not limited
thereto. When the pathway is arranged along two sidewalls of the
vapor precursor compartment (e.g., both inner sidewalls of the pod
trim 410), the pathway along each sidewall may be configured to
converge at a position (e.g., channel outlet 412) that is aligned
with the vapor passage (e.g., 106) of the dispensing body (e.g.,
104) when the pod assembly 402 is received in the through-hole
114.
[0075] In another instance, the vapor channel may be in a form of a
conduit that is arranged in at least one corner of the vapor
precursor compartment. Such a corner may be at the interface of the
first cap 404 and/or the second cap 414 with the inner surface of
the pod trim 410. As a result, the conduit may have a triangular
cross-section, although example embodiments are not limited
thereto. When the conduit is arranged in at least two corners
(e.g., front corners, rear corners, diagonal corners, side corners)
of the vapor precursor compartment, the conduit in each corner may
be configured to converge at a position (e.g., channel outlet 412)
that is aligned with the vapor passage (e.g., 106) of the
dispensing body (e.g., 104) when the pod assembly 402 is received
in the through-hole 114.
[0076] The vapor precursor compartment and the device compartment
may be at opposite ends of the pod assembly 402. The device
compartment may include a memory device. The memory device may be
coded with an electronic identity to permit at least one of an
authentication of the pod assembly 402 and a pairing of operating
parameters specific to a type of the pod assembly 402 when the pod
assembly 402 is inserted into the through-hole of the dispensing
body (e.g., smart calibration). The electronic identity may help
prevent counterfeiting. The operating parameters may help optimize
a vaping experience without placing a burden on the adult vaper to
determine the proper settings. In an example embodiment, the level
of vapor precursor in the pod assembly 402 may be tracked.
Additionally, the activation of the pod assembly 402 may be
restricted once its intended usage life has been exceeded. Thus,
the pod assembly 402 (and 302) may be regarded as a smart pod.
[0077] A side surface of the pod assembly 402 includes at least one
electrical contact 416 and/or data connection 417 (e.g., two or
three electrical contacts and/or data connections). The dispensing
body may be configured to perform at least one of supply power to
and communicate with the pod assembly 402 via the at least one
electrical contact 416. The at least one electrical contact 416 may
be provided at an end of the pod assembly 402 corresponding to the
device compartment. Because of its smart capability, the pod
assembly 402 may communicate with dispensing body and/or another
electronic device (e.g., smart phone). As a result, usage patterns
and other information (e.g., flavor intensity, throat feel, puff
count) may be generated, stored, transferred, and/or displayed. The
smart capability, connecting features, and other related aspects of
the pod assembly, dispensing body, and overall e-vapor apparatus
are additionally discussed in U.S. Application No. 62/151,160
(Atty. Dkt. No. 24000-000200-US-PS1 (ALCS2853)), U.S. Application
No. 62/151,179 (Atty. Dkt. No. 24000-000201-US-PS1 (ALCS2854)), and
U.S. Application No. 62/151,248 (Atty. Dkt. No. 24000-000202-US-PS1
(ALCS2855)), the entire contents of each of which are incorporated
herein by reference.
[0078] FIG. 20 is a view of an e-vapor apparatus with a pod
assembly inserted in a dispensing body according to an example
embodiment. Referring to FIG. 20, an e-vapor apparatus 500 includes
a pod assembly 502 (e.g., smart pod) that is inserted within a
dispensing body 504. The pod assembly 502 may be as previously
described in connection with the pod assembly 302 and the pod
assembly 402. As a result, the pod assembly 502 may be a
hassle-free and leak-free component that can be replaced with
relative ease when the vapor precursor therein runs low/out or when
another flavor is desired.
[0079] FIG. 21 illustrates a device system of a dispensing body
according to an example embodiment. A device system 2100 may be the
system within the dispensing body 104 and the dispensing body
204.
[0080] The device system 2100 includes a controller 2105, a power
supply 2110, actuator controls 2115, a pod electrical/data
interface 2120, device sensors 2125, input/output (I/O) interfaces
2130, vaper indicators 2135, at least one antenna 2140 and a
storage medium 2145. The device system 2100 is not limited to the
features shown in FIG. 21. For example, the device system 2100 may
include additional components. However, for the sake of brevity,
the additional components are not described.
[0081] The controller 2105 may be hardware, firmware, hardware
executing software or any combination thereof. When the controller
2105 is hardware, such existing hardware may include one or more
Central Processing Units (CPUs), digital signal processors (DSPs),
application-specific-integrated-circuits (ASICs), field
programmable gate arrays (FPGAs) computers or the like configured
as special purpose machines to perform the functions of the
processor 220. As stated above, CPUs, DSPs, ASICs and FPGAs may
generally be referred to as processing devices.
[0082] In the event where the controller 2105 is a processor
executing software, the controller 2105 is configured as a special
purpose machine to execute the software, stored in the storage
medium 2145, to perform the functions of the at least one of the
controller 2105.
[0083] As disclosed herein, the term "storage medium", "computer
readable storage medium" or "non-transitory computer readable
storage medium" may represent one or more devices for storing data,
including read only memory (ROM), random access memory (RAM),
magnetic RAM, core memory, magnetic disk storage mediums, optical
storage mediums, flash memory devices and/or other tangible machine
readable mediums for storing information. The term
"computer-readable medium" may include, but is not limited to,
portable or fixed storage devices, optical storage devices, and
various other mediums capable of storing, containing or carrying
instruction(s) and/or data.
[0084] Referring to FIG. 21, the controller 2105 communicates with
the power supply 2110, the actuator control 2115, the pod
electrical/data interface 2120, the device sensors 2125, the
input/output (I/O) interfaces 2130, the vaper indicators 2135, the
at least one antenna 2140.
[0085] The controller 2105 communicates with the CC-NVM in the pod
through the pod electrical/data interface 2120. More specifically,
the controller 2105 may utilize encryption to authenticate the pod.
As will be described, the controller 2105 communicates with the
CC-NVM package to authenticate the pod. More specifically, the
non-volatile memory is encoded during manufacture with product and
other information for authentication.
[0086] The memory device may be coded with an electronic identity
to permit at least one of an authentication of the pod and a
pairing of operating parameters specific to a type of the pod when
the pod assembly 402 is inserted into the through-hole of the
dispensing body. In addition to authenticating based on an
electronic identity of the pod, the controller 2105 may authorize
use of the pod based on an expiration date of the stored vapor
precursor and/or heater encoded into the non-volatile memory of the
CC-NVM. If the controller determines that the expiration date
encoded into the non-volatile memory has passed, the controller may
not authorize use of the pod and disable the e-vaping device.
[0087] The controller 2105 (or storage medium 2145) stores key
material and proprietary algorithm software for the encryption. For
example, encryption algorithms rely on the use of random numbers.
The security of these algorithms depends on how truly random these
numbers are. These numbers are usually pre-generated and coded into
the processor or memory devices. Example embodiments may increase
the randomness of the numbers used for the encryption by using the
puffing parameters e.g. puff durations, intervals between puffs, or
combinations of them, to generate numbers that are more random and
more varying from individual to individual than pre-generated
random numbers. All communications between the controller 2105 and
the pod may be encrypted.
[0088] Moreover, the pod can be used to as a general pay-load
carrier for other information such as software patches for the
e-vaping device. Since encryption is used in all the communications
between the pod and the controller 2105, such information is more
secure and the e-vaping device is less prone to being installed
with malwares or viruses. Use of the CC-NVM as an information
carrier such as data and software updates allows the e-vaping
device to be updated with software without it being connected to
the Internet and for the adult vaper to go through a downloading
process as with most other consumer electronics devices requiring
periodic software updates.
[0089] The controller 2105 may also include a cryptographic
accelerator to allow resources of the controller 2105 to perform
functions other than the encoding and decoding involved with the
authentication. The controller 2105 may also include other security
features such as preventing unauthorized use of communication
channels and preventing unauthorized access to data if a pod or
vaper is not authenticated.
[0090] In addition to a cryptographic accelerator, the controller
2105 may include other hardware accelerators. For example, the
controller 2105 may include a floating point unit (FPU), a separate
DSP core, digital filters and Fast Fourier Transform (FFT)
modules.
[0091] The controller 2105 operates a real time operating system
(RTOS), controls the device system 2100 and may be updated through
communicating with the CC-NVM or when the device system 2100 is
connected with other devices (e.g., a smart phone) through the I/O
interfaces 2130 and/or the antenna 2140. The I/O interfaces 2130
and the antenna 2140 allow the device system 2100 to connect to
various external devices such as smart phones, tablets, and PCs.
For example, the I/O interfaces 2130 may include a micro-USB
connector. The micro-USB connector may be used by the device system
2100 to charge the power source 2110b.
[0092] The controller 2105 may include on-board RAM and flash
memory to store and execute code including analytics, diagnostics
and software upgrades. As an alternative, the storage medium 2145
may store the code. Additionally, in another example embodiment,
the storage medium 2145 may be on-board the controller 2105.
[0093] The controller 2105 may further include on-board clock,
reset and power management modules to reduce an area covered by a
PCB in the dispensing body.
[0094] The device sensors 2125 may include a number of sensor
transducers that provide measurement information to the controller
2105. The device sensors 2125 may include a power supply
temperature sensor, an external pod temperature sensor, a current
sensor for the heater, power supply current sensor, air flow sensor
and an accelerometer to monitor movement and orientation. The power
supply temperature sensor and external pod temperature sensor may
be a thermistor or thermocouple and the current sensor for the
heater and power supply current sensor may be a resistive based
sensor or another type of sensor configured to measure current. The
air flow sensor may be a microelectromechanical system (MEMS) flow
sensor or another type of sensor configured to measure air
flow.
[0095] The data generated from the number of sensor transducers may
be sampled at a sample rate appropriate to the parameter being
measured using a discrete, multi-channel analog-to-digital
converter (ADC).
[0096] The controller 2105 may adapt heater profiles for a vapor
precursor and other profiles based on the measurement information
received from the controller 2105. For the sake of convenience,
these are generally referred to as vaping or vapor profiles.
[0097] The heater profile identifies the power profile to be
supplied to the heater during the few seconds when puffing takes
place. For example of a heater profile can be: deliver maximum
power to the heater when a puff is initiated, but then after a
second or so immediately reduce the power to half way or a quarter
way or so.
[0098] The modulation of electrical power is usually implemented
using pulse wave modulation--instead of flipping an on/off switch
where the power is either full on or off.
[0099] In addition, a heater profile can also be modified by the
extent to which the adult vaper applies negative pressure to the
e-vaping device. The use of the MEMS flow sensor allows puff
strength to be measured and used as feedback to the controller 2105
to adjust the power delivered to the heater of the pod, which may
be referred to as heating or energy delivery.
[0100] When the controller 2105 recognizes the pod currently
installed (e.g., via SKU), the controller 2105 matches an
associated heating profile that is designed for that particular
pod. The controller 2105 and the storage medium 2145 will store
data and algorithms that allow the generation of heating profiles
for all SKUs. The adult vapers may also adjust heating profiles to
suit their preferences.
[0101] As shown in FIG. 21, the controller 2105 sends data to and
receives data from the power supply 2110. The power supply 2110
includes a power source 2110b and a power controller 2110a to
manage the power output by the power source 2110b.
[0102] The power source 2110b may be a Lithium-ion battery or one
of its variants, for example a Lithium-ion polymer battery.
Alternatively, the power source 2110b may be a Nickel-metal hydride
battery, a Nickel cadmium battery, a Lithium-manganese battery, a
Lithium-cobalt battery or a fuel cell. Alternatively, the power
source 2110b may be rechargeable and include circuitry allowing the
battery to be chargeable by an external charging device. In that
case, the circuitry, when charged, provides power for a desired (or
alternatively a pre-determined) number of puffs, after which the
circuitry must be re-connected to an external charging device.
[0103] The power controller 2110a provides commands to the power
source 2110b based on instructions from the controller 2105. For
example, the power supply 2110 may receive a command from the
controller 2105 to provide power to the pod (through the
electrical/data interface 2120) when the pod is authenticated and
the adult vaper activates the device system 2100 (e.g., by
activating a switch such as a toggle button, capacitive sensor, IR
sensor). When the pod is not authenticated, the controller 2105 may
either send no command to the power supply 2110 or send an
instruction to the power supply 2110 to not provide power. In
another example embodiment, the controller 2105 may disable all
operations of the device system 2100 if the pod is not
authenticated.
[0104] In addition to supplying power to the pod, the power supply
2110 also supplies power to the controller 2105. Moreover, the
power controller 2110a may provide feedback to the controller 2105
indicating performance of the power source 2110b.
[0105] The controller 2105 sends data to and receives data from the
at least one antenna 2140. The at least one antenna 2140 may
include a Near Field Communication (NFC) modem and a Bluetooth Low
Energy (LE) modem and/or other modems for other wireless
technologies (e.g., Wi-Fi). In an example embodiment, the
communications stacks are in the modems, but the modems are
controlled by the controller 2105. The Bluetooth LE modem is used
for data and control communications with an application on an
external device (e.g., smart phone). The NFC modem may be used for
pairing of the e-vaping device to the application and retrieval of
diagnostic information. Moreover, the NFC modem may be used to
provide location information (for an adult vaper to find the
e-vaping device) or authentication during a purchase.
[0106] As described above, the device system 2100 may generate and
adjust various profiles for vaping. The controller 2105 uses the
power supply 2110 and the actuator controls 2115 to regulate the
profile for the adult vaper.
[0107] The actuator controls 2115 include passive and active
actuators to regulate a desired vapor profile. For example, the
dispensing body may include an inlet channel within a mouthpiece.
The actuator controls 2115 may control the inlet channel based on
commands from the controller 2105 associated with the desired vapor
profile.
[0108] Moreover, the actuator controls 2115 are used to energize
the heater in conjunction with the power supply 2110. More
specifically, the actuator controls 2115 are configured to generate
a drive waveform associated with the desired vaping profile. As
described above, each possible profile is associated with a drive
waveform. Upon receiving a command from the controller 2105
indicating the desired vaping profile, the actuator controls 2115
may produce the associated modulating waveform for the power supply
2110.
[0109] The controller 2105 supplies information to the vaper
indicators 2135 to indicate statuses and occurring operations to
the adult vaper. The vaper indicators 2135 include a power
indicator (e.g., LED) that may be activated when the controller
2105 senses a button press by the adult vaper. The vaper indicators
2135 may also include a vibrator, speaker, an indicator for current
state of a vaper-controlled vaping parameter (e.g., vapor volume)
and other feedback mechanisms.
[0110] Furthermore, the device system 2100 may include a number of
on-product controls 2150 that provide commands from an adult vaper
to the controller 2105. The on-product controls 2150 include an
on-off button which may be a toggle button, capacitive sensor or IR
sensor, for example. The on-product controls 2150 may further
include a vaping control button (if the adult vaper desires to
override the buttonless vaping feature to energize the heater), a
hard reset button, a touch based slider control (for controlling
setting of a vaping parameter such as puff volume), a vaping
control button to activate the slider control and a mechanical
adjustment for an air inlet.
[0111] Once a pod is authenticated, the controller 2105 operates
the power supply 2110, the actuator controls 2115, vaper indicators
2135 and antenna 2140 in accordance with an adult vaper using the
e-vaping device and the information stored by the CC-NVM on the
pod. Moreover, the controller 2105 may include logging functions
and be able to implement algorithms to calibrate the e-vaping
device. The logging functions are executed by the controller 2105
to record usage data as well any unexpected events or faults. The
recorded usage data may be used for diagnostics and analytics. The
controller 2105 may calibrate the e-vaping device using buttonless
vaping, a vaper configuration and the stored information on the
CC-NVM including puff sensing, vapor precursor level, and vapor
precursor composition. For example, the controller 2105 may command
the power supply 2110 to supply power to the heater in the pod
based on a vaping profile associated with the vapor precursor
composition in the pod. Alternatively, a vaping profile may be
encoded in the CC-NVM and utilized by the controller 2105.
[0112] FIG. 22 illustrates a pod system diagram of a dispensing
body according to an example embodiment. A pod system 2200 may be
within the pod assembly 502, the pod assembly 302 and the pod
assembly 402.
[0113] As shown in FIG. 22, the pod system 2200 includes a CC-NVM
2205, a body electrical/data interface 2210, a heater 2215 and pod
sensors 2220. The pod system 2200 communicates with the device
system 2100 through the body electrical/data interface 2210 and the
pod electrical/data interface 2120. The body electrical/data
interface 2210 may correspond to the battery contacts 416 and data
connection 417 connected within the pod assembly 402, shown in FIG.
19, for example. Thus, the CC-NVM 2205 is coupled to the data
connection 417 and the battery contacts 416.
[0114] The CC-NVM 2205 includes a cryptographic coprocessor 2205a
and a non-volatile memory 2205b. The controller 2105 may access the
information stored on the non-volatile memory 2205b for the
purposes of authentication and operating the pod by communicating
with the cryptographic coprocessor 2205a.
[0115] The non-volatile memory 2205b may be coded with an
electronic identity to permit at least one of an authentication of
the pod and a pairing of operating parameters specific to a type of
the pod when the pod assembly is inserted into the through-hole of
the dispensing body. In addition to authenticating based on an
electronic identity of the pod, the controller 2105 may authorize
use of the pod based on an expiration date of the stored vapor
precursor and/or heater encoded into the non-volatile memory 2205b
of the CC-NVM. If the controller determines that the expiration
date encoded into the non-volatile memory 2205b has passed, the
controller may not authorize use of the pod and disable the
e-vaping device.
[0116] Moreover, the non-volatile memory 2205b may store
information such as a stock keeping unit (SKU) of the vapor
precursor in the vapor precursor compartment (including vapor
precursor composition), software patches for the device system
2100, product usage information such as puff count, puff duration,
and vapor precursor level. The non-volatile memory 2205b may store
operating parameters specific to the type of the pod and the vapor
precursor composition. For example, the non-volatile memory 2205b
may store the electrical and mechanical design of the pod for use
by the controller 2105 to determine commands corresponding to a
desired vaping profile.
[0117] The vapor precursor level in the pod may be determined in
one of two ways, for example. In one example embodiment, one of the
pod sensors 2220 directly measures the vapor precursor level in the
pod.
[0118] In another example embodiment, the non-volatile memory 2205b
stores the number of puffs taken from the pod and the controller
2105 uses the number of puffs taken as a proxy to the amount of
vapor precursor that is vaporized.
[0119] The controller 2105 and/or the storage medium 2145 may store
vapor precursor calibration data that identifies an operating point
for the vapor precursor composition. The vapor precursor
calibration data include data describing how flow rate changes with
a remaining vapor precursor level or how volatility changes with an
age of the vapor precursor and may be used for calibration by the
controller 2105. The vapor precursor calibration data may be stored
by the controller 2105 and/or the storage medium 2145 in a table
format. The vapor precursor calibration data allows the controller
2105 to equate the number of puffs taken to the amount of vapor
precursor that is vaporized.
[0120] The controller 2105 writes the vapor precursor level and
number of puffs taken back to the non-volatile memory 2205b in the
pod so if the pod is removed from the dispensing body and later on
re-installed, an accurate vapor precursor level of the pod will
still be known by the controller 2105.
[0121] The operating parameters (e.g., power supply, power
duration, air channel control) are referred to as a vaping profile.
Moreover, the non-volatile memory 2205b may record information
communicated by the controller 2105. The non-volatile memory 2205b
may retain the recorded information even when the dispensing body
becomes disconnected from the pod.
[0122] In an example embodiment, the non-volatile memory 2205b may
be a programmable read only memory.
[0123] The heater 2215 is actuated by the controller 2105 and
transfers heat to the vapor precursor in accordance with the
commanded profile (volume, temperature (based on power profile) and
flavor) from the controller 2105.
[0124] The heater 2215 may be a wire coil surrounding a wick, a
mesh, a surface or made out of a ceramic material for example.
Examples of suitable electrically resistive materials include
titanium, zirconium, tantalum and metals from the platinum group.
Examples of suitable metal alloys include stainless steel, nickel-,
cobalt-, chromium-, aluminum-titanium-zirconium-, hafnium-,
niobium-, molybdenum-, tantalum-, tungsten-, tin-, gallium-,
manganese- and iron-containing alloys, and super-alloys based on
nickel, iron, cobalt, stainless steel. For example, the heater may
be formed of nickel aluminides, a material with a layer of alumina
on the surface, iron aluminides and other composite materials, the
electrically resistive material may optionally be embedded in,
encapsulated or coated with an insulating material or vice-versa,
depending on the kinetics of energy transfer and the external
physicochemical properties required. In one embodiment, the heater
comprises at least one material selected from the group consisting
of stainless steel, copper, copper alloys, nickel-chromium alloys,
superalloys and combinations thereof. In an embodiment, the heater
2215 is formed of nickel-chromium alloys or iron-chromium alloys.
In one embodiment, the heater 2215 can be a ceramic heater having
an electrically resistive layer on an outside surface thereof.
[0125] In another embodiment, the heater 2215 may be constructed of
an iron-aluminide (e.g., FeAl or Fe.sub.3Al), such as those
described in commonly owned U.S. Pat. No. 5,595,706 to Sikka et al.
filed Dec. 29, 1994, or nickel aluminides (e.g., NiAl), the entire
contents of which are hereby incorporate by reference.
[0126] The heater 2215 may determine an amount of vapor precursor
to heat based on feedback from the pod sensors or the controller
2105. The flow of vapor precursor may be regulated by a
micro-capillary or wicking action. Moreover, the controller 2105
may send commands to the heater 2215 to adjust an air inlet to the
heater 2215.
[0127] The pod sensor 2220 may include a heater temperature sensor,
vapor precursor flow rate monitor and air flow monitor. The heater
temperature sensor may be a thermistor or thermocouple and the flow
rate sensing may be performed by the pod system 2200 using
electrostatic interference or an in-liquid rotator. The air flow
sensor may be a microelectromechanical system (MEMS) flow sensor or
another type of sensor configured to measure air flow.
[0128] The data generated from the pod sensors 2220 may be sampled
at a sample rate appropriate to the parameter being measured using
a discrete, multi-channel analog-to-digital converter (ADC).
[0129] While a number of example embodiments have been disclosed
herein, it should be understood that other variations may be
possible. Such variations are not to be regarded as a departure
from the spirit and scope of the present disclosure, and all such
modifications as would be obvious to one skilled in the art are
intended to be included within the scope of the following
claims.
