Best Mode for Carrying Out the Invention
[0011] Some detailed exemplary embodiments are disclosed herein. However, the details of the specific structural and functional aspects disclosed herein are merely exemplary for the purpose of explaining the exemplary embodiments. However, the exemplary embodiments can be embodied in numerous alternative forms and should not be construed as limited to only the exemplary embodiments described herein.
[0012] Accordingly, while exemplary embodiments are subject to various modifications and alternative forms, they are shown in the drawings as examples and are described in detail herein. However, it is not intended to limit the embodiments to any particular form disclosed; on the contrary, the exemplary embodiments encompass all variations, equivalents, and alternatives. Similar figures refer to similar elements throughout the description of the figures.
[0013] Naturally, when an element or layer is referred to as "on top of," "connected to," "linked to," "attached to," "adjacent to," or "covering" another element or layer, there may be other elements or layers that are directly on top of, directly connected to, directly linked to, directly attached to, directly adjacent to, or directly cover or interposed to the other element or layer. In contrast, when an element is referred to as "directly on top of," "directly connected to," or "directly linked to" another element or layer, there are no interposing elements or layers. Similar numbers refer to similar elements throughout this specification. As used herein, the term "and / or" includes combinations or partial combinations of one or more of the related enumerated items, or all of them.
[0014] Naturally, terms such as first, second, third, etc., may be used herein to describe various elements, regions, layers, and / or sections, and these elements, regions, layers, and / or sections should not be limited by these terms. These terms are used solely to distinguish one element, region, layer, or section from another. Accordingly, the first element, region, layer, or section considered below may also be called the second element, region, layer, or section without departing from the teachings of the exemplary embodiments.
[0015] Spatial relationship terms (e.g., βdown,β βbelow,β βbottom,β βup,β βtop,β and similar) may be used herein to facilitate the description of the relationship between one element or feature and another when illustrating them in a figure. Spatial relationship terms should be understood as intended to encompass different orientations of the device during use or operation, in addition to the orientation depicted in the figure. For example, if the device in the figure is turned upside down, an element described as βbelowβ or βbelowβ another element or feature will subsequently be oriented βupβ the other element or feature. Thus, the term βbelowβ may encompass both upward and downward orientations. The device may be oriented in other ways (by rotating 90 degrees or in other orientations), and the spatial relationship terms used herein should be interpreted accordingly.
[0016] The terms used herein are for illustrative purposes only and are not intended to limit the exemplary embodiments. The singular forms βa,β βan,β and βtheβ as used herein are intended to include the plural, unless the context clearly indicates otherwise. When used herein, the terms βincludes,β βincluding,β βcomprises,β and / or βcomprisingβ identify the presence of the described feature, integer, process, operation, and / or element, but do not exclude the presence or addition of one or more other features, integers, processes, operations, elements, and / or groups thereof.
[0017] Where the terms βsameβ or βidenticalβ are used in the description of exemplary embodiments, there is naturally some degree of inaccuracy. Therefore, when one element or value is referred to as being the same as another element or value, it is naturally assumed that the elements or values ββare the same as the other elements or values ββwithin a manufacturing or operating tolerance range (e.g., Β±10 percent).
[0018] The terms βaboutβ or βsubstantiallyβ are used herein in relation to numerical values, and naturally, these numerical values ββinclude manufacturing or operating tolerances (e.g., Β±10 percent) before and after the stated numerical value. Furthermore, when the words βgenerallyβ and βsubstantiallyβ are used in relation to geometric shapes, naturally, accuracy of the geometric shape is not required, but tolerances for the shape are within the scope of this disclosure.
[0019] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as those generally understood by those skilled in the art to the extent of the exemplary embodiments. Terms (including those defined in commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as an ideal or overly formal meaning, unless explicitly defined so herein, it will be further understood.
[0020] The hardware may be implemented using processing or control circuits, including, but not limited to, one or more processors, one or more central processing units (CPUs), one or more microcontrollers, one or more arithmetic logic units (ALUs), one or more digital signal processors (DSPs), one or more microcomputers, one or more field-programmable gate arrays (FPGAs), one or more system-on-a-chip (SoCs), one or more programmable logic units (PLUs), one or more microprocessors, one or more application-specific integrated circuits (ASICs), or any other devices capable of responding to and executing instructions in a defined manner.
[0021] Figure 1 is a front view of a nicotine e-vaping device according to an exemplary embodiment. Figure 2 is a side view of the nicotine e-vaping device of Figure 1. Figure 3 is a rear view of the nicotine e-vaping device of Figure 1. Referring to Figures 1-3, the nicotine e-vaping device 500 includes a device body 100 configured to receive a nicotine pod assembly 300. The nicotine pod assembly 300 is a modular article configured to hold a nicotine pre-vapor formulation. The nicotine pre-vapor formulation is a material or combination of materials that can be transformed into a nicotine vapor. For example, the nicotine pre-vapor formulation may include liquid, solid, and / or gel formulations. These may include, for example, but are not limited to, water, oil, emulsion, beads, solvent, active ingredient, ethanol, plant extract, nicotine, natural or artificial flavor, vapor-forming agents such as glycerin and propylene glycol, and / or any other components that may be suitable for vaping. During vaping, the nicotine e-vaping device 500 is configured to heat a nicotine pre-vapor formulation to generate nicotine vapor. Nicotine vapor, nicotine aerosol, and nicotine dispersion are interchangeable and refer to substances generated or output by the disclosed device, the claimed device, and / or equivalent, such substances containing nicotine. The nicotine e-vaping device 500 may be considered an electronic nicotine delivery system (ENDS).
[0022] As shown in Figures 1 and 3, the nicotine e-vaping device 500 extends in the longitudinal direction and has a length greater than its width. Furthermore, as shown in Figure 2, the length of the nicotine e-vaping device 500 is also greater than its thickness. Furthermore, the width of the nicotine e-vaping device 500 may also be greater than its thickness. Assuming an xyz Cartesian coordinate system, the length of the nicotine e-vaping device 500 may be measured in the y direction, the width may be measured in the x direction, and the thickness may be measured in the z direction. Based on its front, side, and rear views, the nicotine e-vaping device 500 may have a substantially linear form with tapered ends, but exemplary embodiments are not limited thereto.
[0023] The device body 100 includes a front cover 104, a frame 106, and a rear cover 108. The front cover 104, frame 106, and rear cover 108 form a device housing that encloses mechanical components, electronic components, and / or circuits related to the operation of the nicotine e-vaping device 500. For example, the device housing of the device body 100 may enclose a power supply configured to power the nicotine e-vaping device 500, which may include supplying current to the nicotine pod assembly 300. Furthermore, when assembled, the front cover 104, frame 106, and rear cover 108 may constitute the majority of the visible portion of the device body 100. The device housing may be considered to include all components of the device body 100 except for the mouthpiece 102. In other words, the mouthpiece 102 and the device housing may be considered to form the device body 100.
[0024] The front cover 104 (e.g., the first cover) defines a primary opening configured to accommodate a bezel structure 112. The primary opening may have a rounded rectangular shape, but other shapes are possible depending on the shape of the bezel structure 112. The bezel structure 112 defines a through-hole 150 configured to receive a nicotine pod assembly 300. The through-hole 150 is described in more detail herein, for example, in reference to Figure 9.
[0025] The front cover 104 also defines a secondary opening configured to accommodate an optical guide arrangement. The secondary opening may resemble a slot (e.g., a segmented slot), but other shapes are possible depending on the shape of the optical guide arrangement. In an exemplary embodiment, the optical guide arrangement includes an optical guide lens 116. Furthermore, the front cover 104 defines tertiary and quaternary openings configured to accommodate a first button 118 and a second button 120. Each of the tertiary and quaternary openings may resemble a rounded rectangle, but other shapes are possible depending on the shape of the button. The first button housing 122 is configured to expose a first button lens 124, and the second button housing 123 is configured to expose a second button lens 126.
[0026] The operation of the nicotine e-vaping device 500 may be controlled by a first button 118 and a second button 120. For example, the first button 118 may be a power button, and the second button 120 may be an intensity button. Although two buttons are illustrated in the drawings, more (or fewer) buttons may be provided, depending on the available features and the desired user interface.
[0027] The frame 106 (e.g., base frame) is the central support structure for the device body 100 (and the entire nicotine e-vaping device 500). The frame 106 may be called the chassis. The frame 106 includes a proximal end, a distal end, and a pair of side sections between the proximal and distal ends. The proximal and distal ends may also be called the downstream end and upstream end, respectively. As used herein, βproximalβ (and conversely βdistalβ) refers to the adult e-vaping device user during vaping, and the terms βdownstreamβ (and conversely βupstreamβ) refer to the flow of nicotine vapor. A bridging section may be provided between the opposing inner surfaces of the side sections (e.g., approximately midway along the length of the frame 106) for further strength and stability. The frame 106 may be integrally formed to be a monolithic structure.
[0028] Regarding the structural materials, the frame 106 may be formed from an alloy or plastic. The alloy (e.g., die-cast grade, machinable grade) may be an aluminum (Al) alloy or a zinc (Zn) alloy. The plastic may be polycarbonate (PC), acrylonitrile butadiene styrene (ABS), or a combination thereof (PC / ABS). For example, the polycarbonate may be LUPOY SC1004A. Furthermore, the frame 106 may be provided with a surface finish for functional and / or aesthetic reasons (e.g., to provide a high-quality appearance). In exemplary embodiments, the frame 106 (e.g., formed from an aluminum alloy) may be anodized. In another embodiment, the frame 106 (e.g., formed from a zinc alloy) may be coated with hard enamel or painted. In yet another embodiment, the frame 106 (e.g., formed from polycarbonate) may be metallized. In yet another embodiment, the frame 106 (e.g., formed from acrylonitrile butadiene styrene) may be electroplated. Naturally, the structural materials relating to the frame 106 may also apply to the front cover 104, the rear cover 108, and / or other suitable parts of the nicotine e-vaping device 500.
[0029] The rear cover 108 (e.g., a second cover) also defines an opening configured to accommodate the bezel structure 112. The opening may have a rounded rectangular shape, but other shapes are possible depending on the shape of the bezel structure 112. In exemplary embodiments, the opening of the rear cover 108 is smaller than the primary opening of the front cover 104. Furthermore, although not shown, optical guides and / or buttons may be provided on the rear of the nicotine e-vaping device 500 in addition to (or instead of) the optical guides and buttons on the front of the nicotine e-vaping device 500.
[0030] The front cover 104 and the rear cover 108 may be configured to engage with the frame 106 via snap-fit ββarrangements. For example, the front cover 104 and / or the rear cover 108 may include clips configured to interlock with corresponding mating members of the frame 106. In a non-limiting embodiment, the clips may be in the form of tabs having orifices configured to receive corresponding mating members of the frame 106 (e.g., projections with inclined edges). Alternatively, the front cover 104 and / or the rear cover 108 may be configured to engage with the frame 106 via press-fit (also known as press-fit or friction-fit). However, naturally, the front cover 104, the frame 106, and the rear cover 108 may be connected by other suitable arrangements and techniques.
[0031] The device body 100 also includes a mouthpiece 102. The mouthpiece 102 can be fixed to the proximal end of the frame 106. Furthermore, in an exemplary embodiment where the frame 106 is sandwiched between a front cover 104 and a rear cover 108, as shown in Figure 2, the mouthpiece 102 may abut against the front cover 104, the frame 106, and the rear cover 108. Furthermore, in a non-limiting embodiment, the mouthpiece 102 may be coupled to the device housing via a bayonet connection.
[0032] Figure 4 is a proximal end view of the nicotine e-vaping device of Figure 1. Referring to Figure 4, the outlet surface of the mouthpiece 102 defines a plurality of vapor outlets. In a non-limiting embodiment, the outlet surface of the mouthpiece 102 may be elliptical in shape. Furthermore, the outlet surface of the mouthpiece 102 may include a first crossbar corresponding to the major axis of the elliptical outlet surface and a second crossbar corresponding to the minor axis of the elliptical outlet surface. Furthermore, the first and second crossbars intersect at a right angle and may be integrally formed parts of the mouthpiece 102. The outlet surface is shown defining four vapor outlets, but of course, exemplary embodiments are not limited thereto. For example, the outlet surface may define fewer than four (e.g., one, two) vapor outlets or more than four (e.g., six, eight) vapor outlets.
[0033] Figure 5 is a distal end view of the nicotine e-vaping device of Figure 1. Referring to Figure 5, the distal end of the nicotine e-vaping device 500 includes a port 110. Port 110 is configured to receive current from an external power source (e.g., via a USB / mini USB cable) to charge the internal power supply within the nicotine e-vaping device 500. Furthermore, port 110 may also be configured to transmit and / or receive data to and from another nicotine e-vaping device or other electronic devices (e.g., a phone, tablet, or computer) (e.g., via a USB / mini USB cable). In addition, the nicotine e-vaping device 500 may be configured for wireless communication with another electronic device, such as a phone, via application software (app) installed on the electronic device. In such examples, an adult e-vaping device user may control the nicotine e-vaping device 500 or interface with it in other ways through the app (e.g., locate the nicotine e-vaping device, check usage information, change operating parameters).
[0034] Figure 6 is a perspective view of the nicotine e-vaping device of Figure 1. Figure 7 is a magnified view of the pod inlet of Figure 6. Referring to Figures 6-7 and as briefly mentioned above, the nicotine e-vaping device 500 includes a nicotine pod assembly 300 configured to hold a nicotine pre-vapor formulation. The nicotine pod assembly 300 has an upstream end (facing the optical guide arrangement) and a downstream end (facing the mouthpiece 102). In a non-limiting embodiment, the upstream end is the face opposite the downstream end of the nicotine pod assembly 300. The upstream end of the nicotine pod assembly 300 defines the pod inlet 322. The device body 100 defines a through-hole (e.g., the through-hole 150 in Figure 9) configured to receive the nicotine pod assembly 300. In an exemplary embodiment, the bezel structure 112 of the device body 100 defines the through-hole and includes an upstream edge. In particular, as shown in Figure 7, the upstream edge of the bezel structure 112 is angled (for example, sinking inward) so that the pod inlet 322 is exposed when the nicotine pod assembly 300 is placed in the through-hole of the device body 100.
[0035] For example, rather than following the contour of the front cover 104 (which is coplanar relative to the front of the nicotine pod assembly 300 and therefore covers the pod inlet 322), the upstream edge of the bezel structure 112 is in the form of a scoop configured to direct ambient air into the pod inlet 322. This angled / scoop configuration (which may be, for example, curved) may help reduce or prevent blockage of the air inlet (e.g., the pod inlet 322) of the nicotine e-vaping device 500. The depth of the scoop may be such that less than half (e.g., less than a quarter) of the upstream end face of the nicotine pod assembly 300 is exposed. Furthermore, in a non-limiting embodiment, the pod inlet 322 is in the form of a slot. Furthermore, if the device body 100 is considered to extend in a first direction, the slot may be considered to extend in a second direction which is transverse to the first direction.
[0036] Figure 8 is a cross-sectional view of the nicotine e-vaping device of Figure 6. In Figure 8, the cross-section is cut along the longitudinal axis of the nicotine e-vaping device 500. As shown, the device body 100 and the nicotine pod assembly 300 include mechanical components, electronic components, and / or circuits related to the operation of the nicotine e-vaping device 500, which are described in more detail herein and / or incorporated herein by reference. For example, the nicotine pod assembly 300 may include mechanical components configured to release a nicotine pre-vaper formulation from an internally sealed storage when activated. The nicotine pod assembly 300 may also have mechanical aspects configured to engage with the device body 100 to facilitate the insertion and seating of the nicotine pod assembly 300.
[0037] Furthermore, the nicotine pod assembly 300 may be a βsmart podβ including electronic components and / or circuits configured to store, receive, and / or transmit information to and from the device body 100. Such information may be used to authenticate the nicotine pod assembly 300 for use with the device body 100 (e.g., to prevent the use of unauthorized / counterfeit nicotine pod assemblies). Furthermore, the information may be used to identify the type of nicotine pod assembly 300, which is then correlated with a vaping profile based on the identified type. The vaping profile may be designed to define general parameters for heating the nicotine prevaper formulation and may also be subject to adjustment, purification, or other adjustments by an adult e-vaping device user before and / or during vaping.
[0038] The nicotine pod assembly 300 may also communicate other information that may be relevant to the operation of the nicotine e-vaping device 500 to the device body 100. Examples of relevant information may include the level of nicotine pre-vapor formulation in the nicotine pod assembly 300 and / or the length of time that has elapsed since the nicotine pod assembly 300 was inserted into the device body 100 and activated. For example, if the nicotine pod assembly 300 has been inserted into the device body 100 and activated for a period longer than a certain period (e.g., longer than 6 months), the nicotine e-vaping device 500 may not allow vaping, and the adult e-vaping device user may be prompted to replace the nicotine pod assembly 300 with a new one, even if the nicotine pod assembly 300 still contains an appropriate level of nicotine pre-vapor formulation.
[0039] The device body 100 may include mechanical components (e.g., complementary structures) configured to engage, hold, and / or activate the nicotine pod assembly 300. Furthermore, the device body 100 may include electronic components and / or circuits configured to receive current and charge an internal power source (e.g., a battery), which are then configured to power the nicotine pod assembly 300 during vaping. Additionally, the device body 100 may include electronic components and / or circuits configured to communicate with the nicotine pod assembly 300, different nicotine e-vaping devices, other electronic devices (e.g., telephones, tablets, computers), and / or adult e-vaping device users. Information communicated may include pod-specific data, current vaping details, and / or past vaping patterns / history. Adult e-vaping device users may be notified of such communications using feedback that is tactile (e.g., vibration), auditory (e.g., beeping), and / or visual (e.g., colored / flashing light). Charging and / or information communication may be performed using port 110 (for example, via a USB / mini USB cable).
[0040] Figure 9 is a perspective view of the device body of the nicotine e-vaping device of Figure 6. Referring to Figure 9, the bezel structure 112 of the device body 100 defines a through-hole 150. The through-hole 150 is configured to receive a nicotine pod assembly 300. To facilitate the insertion and seating of the nicotine pod assembly 300 into the through-hole 150, the upstream edge of the bezel structure 112 includes a first upstream projection 128a and a second upstream projection 128b. The through-hole 150 may have a rectangular shape with rounded corners. In an exemplary embodiment, the first upstream projection 128a and the second upstream projection 128b are integrally formed with the bezel structure 112 and are positioned at the two rounded corners of the upstream edge.
[0041] The downstream side wall of the bezel structure 112 may define a first downstream opening, a second downstream opening, and a third downstream opening. The retaining structure, including the first downstream projection 130a and the second downstream projection 130b, engages with the bezel structure 112 such that the first downstream projection 130a and the second downstream projection 130b project into the through hole 150, respectively, through the first downstream opening and the second downstream opening of the bezel structure 112. Furthermore, the distal end of the mouthpiece 102 extends into the through hole 150, passing through the third downstream opening of the bezel structure 112 and being located between the first downstream projection 130a and the second downstream projection 130b.
[0042] Figure 10 is a front view of the device body shown in Figure 9. Referring to Figure 10, the device body 100 includes a device electrical connector 132 located upstream of the through-hole 150. The device electrical connector 132 of the device body 100 is configured to electrically engage with the nicotine pod assembly 300 placed within the through-hole 150. As a result, during vaping, power can be supplied from the device body 100 to the nicotine pod assembly 300 via the device electrical connector 132. Furthermore, data can be transmitted and / or received between the device body 100 and the nicotine pod assembly 300 via the device electrical connector 132.
[0043] Figure 11 is an enlarged perspective view of the through-hole in Figure 10. Referring to Figure 11, the first upstream projection 128a, the second upstream projection 128b, the first downstream projection 130a, the second downstream projection 130b, and the distal end of the mouthpiece 102 protrude into the through-hole 150. In exemplary embodiments, the first upstream projection 128a and the second upstream projection 128b are fixed structures (e.g., fixed pivots), and the first downstream projection 130a and the second downstream projection 130b are pullable structures (e.g., retractable members). For example, the first projection 130a and the second downstream projection 130b may be configured to be extended by default (e.g., spring-loaded), or they may be configured to be temporarily retracted (and reversibly returned to the extended state) to facilitate insertion of the nicotine pod assembly 300.
[0044] In particular, when inserting the nicotine pod assembly 300 into the through hole 150 of the device body 100, the recess on the upstream end face of the nicotine pod assembly 300 first engages with the first upstream projection 128a and the second upstream projection 128b, and then the nicotine pod assembly 300 is rotated (around the first upstream projection 128a and the second upstream projection 128b) until the recess on the downstream end face of the nicotine pod assembly 300 engages with the first downstream projection 130a and the second downstream projection 130b. In such an example, the axis of rotation of the nicotine pod assembly 300 (during rotation) may be perpendicular to the longitudinal axis of the device body 100. Furthermore, the first downstream projection 130a and the second downstream projection 130b, which can be biased to be pullable, retract and elastically extend as the nicotine pod assembly 300 is pivoted into the through hole 150, and may engage with a recess on the downstream end face of the nicotine pod assembly 300. Moreover, the engagement of the first downstream projection 130a and the second downstream projection 130b with the recess on the downstream end face of the nicotine pod assembly 300 may generate tactile and / or auditory feedback (e.g., an audible click) to inform an adult e-vaping device user that the nicotine pod assembly 300 is properly positioned in the through hole 150 of the device body 100.
[0045] Figure 12 is an enlarged perspective view of the device electrical contacts in Figure 10. The device electrical contacts of the device body 100 are configured to engage with the pod electrical contacts of the nicotine pod assembly 300 when the nicotine pod assembly 300 is placed in the through-hole 150 of the device body 100. Referring to Figure 12, the device electrical contacts of the device body 100 include a device electrical connector 132. The device electrical connector 132 includes power contacts and data contacts. The power contacts of the device electrical connector 132 are configured to supply power from the device body 100 to the nicotine pod assembly 300. As illustrated, the power contacts of the device electrical connector 132 include a first power contact and a second power contact (located closer to the front cover 104 than to the rear cover 108). The first power contact (e.g., the power contact adjacent to the first upstream projection 128a) may be a separate, single, integrated structure from the second power contact and include a projection that extends into the through-hole 150 when assembled. Similarly, the second power contact (e.g., the power contact adjacent to the second upstream projection 128b) may be a separate, single, integrated structure from the second power contact, and may include a projection that extends into the through-hole 150 when assembled. The first and second power contacts of the device electrical connector 132 may be mounted and biased so as to extend into the through-hole 150 by default, and so as to retract (e.g., independently) from the through-hole 150 when subjected to a force that overcomes bias.
[0046] The data contacts of the device electrical connector 132 are configured to transmit data between the nicotine pod assembly 300 and the device body 100. As shown in the figure, the data contacts of the device electrical connector 132 include five rows of protrusions (positioned closer to the rear cover 108 than to the front cover 104). The data contacts of the device electrical connector 132 may be a separate structure that extends into the through-hole 150 when assembled. The data contacts of the device electrical connector 132 may also be tractably mounted and biased (e.g., via a meandering structure and / or using a spring) so that they extend into the through-hole 150 by default and retract (e.g., independently) from the through-hole 150 when subjected to a force that overcomes the bias. For example, when the nicotine pod assembly 300 is inserted into the through-hole 150 of the device body 100, the pod electrical contacts of the nicotine pod assembly 300 are pressed against the corresponding device electrical contacts of the device body 100. As a result, the power and data contacts of the device electrical connector 132 retract into the device body 100 (e.g., at least partially), but remain pressed against the corresponding pod electrical contacts due to their elastic arrangement, thereby helping to ensure proper electrical connection between the device body 100 and the nicotine pod assembly 300. Furthermore, such connection may also be mechanically secure and have minimal contact resistance, enabling reliable and accurate transmission and / or transmission of power and / or signals between the device body 100 and the nicotine pod assembly 300. While various embodiments relating to the device electrical contacts of the device body 100 have been described, the exemplary embodiments are, of course, not limited thereto, and other configurations may be utilized.
[0047] Figure 13 is a partially exploded view relating to the mouthpiece of Figure 12. Referring to Figure 13, the mouthpiece 102 is configured to engage with the device housing via a retaining structure 140. In an exemplary embodiment, the retaining structure 140 is located primarily between the frame 106 and the bezel structure 112. As shown, the retaining structure 140 is positioned within the device housing such that its proximal end extends through the proximal end of the frame 106. The retaining structure 140 may extend slightly beyond the proximal end of the frame 106 or substantially equal to it. The proximal end of the retaining structure 140 is configured to receive the distal end of the mouthpiece 102. The proximal end of the retaining structure 140 may be a female end, and the distal end of the mouthpiece may be a male end.
[0048] For example, the mouthpiece 102 may be connected to the retaining structure 140 using a bayonet connection (e.g., reversibly connected). In such an example, the female end of the retaining structure 140 may define a pair of opposing L-shaped slots, and the male end of the mouthpiece 102 may have an opposing radial member 134 (e.g., a radial pin) configured to engage with the L-shaped slots of the retaining structure 140. Each of the L-shaped slots of the retaining structure 140 may have a longitudinal portion and a circumferential portion. Optionally, the end of the circumferential portion may have a serration to help reduce or prevent the possibility of the radial member 134 of the mouthpiece 102 being accidentally disengaged. In a non-limiting embodiment, the longitudinal portion of the L-shaped slot extends parallel to the longitudinal axis of the device body 100, and the circumferential portion of the L-shaped slot extends around the longitudinal axis (e.g., the central axis) of the device body 100. As a result, in order to connect the mouthpiece 102 to the device housing, first the mouthpiece 102 shown in Figure 13 is rotated 90 degrees to align the radial member 134 with the entrance to the long axis portion of the L-shaped slot of the retaining structure 140. Next, the mouthpiece 102 is inserted into the retaining structure 140 so that the radial member 134 slides along the long axis portion of the L-shaped slot until it reaches the joint with each of the circumferential portions. At this point, the mouthpiece 102 is then rotated so that the radial member 134 moves across the circumferential portions until it reaches each end. If there are serif portions at each end, tactile and / or auditory feedback (e.g., an audible click) may be generated to inform the adult e-vaping device user that the mouthpiece 102 is properly connected to the device housing.
[0049] The mouthpiece 102 defines a vapor passage 136 through which nicotine vapor flows during vaping. The vapor passage 136 is in fluid communication with a through-hole 150 (where the nicotine pod assembly 300 is placed within the device body 100). The proximal end of the vapor passage 136 may include a flared portion. Furthermore, the mouthpiece 102 may include an end cover 138. The end cover 138 may be tapered from its distal end to its proximal end. The outlet surface of the end cover 138 defines multiple vapor outlets. Four vapor outlets are shown on the end cover 138, but of course, exemplary embodiments are not limited thereto.
[0050] Figure 14 is an exploded view of the bezel structure of Figure 9. Figure 15 is an enlarged perspective view of the mouthpiece, spring, retaining structure, and bezel structure of Figure 14. Referring to Figures 14-15, the bezel structure 112 includes an upstream side wall and a downstream side wall. The upstream side wall of the bezel structure 112 defines a connector opening 146. The connector opening 146 is configured to expose or receive the device electrical connector 132 of the device body 100. The downstream side wall of the bezel structure 112 defines a first downstream opening 148a, a second downstream opening 148b, and a third downstream opening 148c. The first downstream opening 148a and the second downstream opening 148b of the bezel structure 112 are configured to receive the first downstream projection 130a and the second downstream projection 130b of the retaining structure 140, respectively. The third downstream opening 148c of the bezel structure 112 is configured to receive the distal end of the mouthpiece 102.
[0051] As shown in Figure 14, the first downstream projection 130a and the second downstream projection 130b are located on the concave side surface of the retaining structure 140. As shown in Figure 15, the first post 142a and the second post 142b are located on the opposing convex side surfaces of the retaining structure 140. The first spring 144a and the second spring 144b are positioned on the first post 142a and the second post 142b, respectively. The first spring 144a and the second spring 144b are configured to bias the retaining structure 140 against the bezel structure 112.
[0052] When assembled, the bezel structure 112 may be secured to the frame 106 via a pair of posts adjacent to the connector opening 146, above the underside of the upstream edge of the bezel structure 112. Furthermore, the retaining structure 140 abuts against the bezel structure 112 such that the first downstream projection 130a and the second downstream projection 130b extend through the first downstream opening 148a and the second downstream opening 148b, respectively. The mouthpiece 102 is connected to the retaining structure 140 such that the distal end of the mouthpiece 102 extends through the retaining structure 140 and the third downstream opening 148c of the bezel structure 112. The first spring 144a and the second spring 144b are located between the frame 106 and the retaining structure 140.
[0053] When the nicotine pod assembly 300 is inserted into the through-hole 150 of the device body 100, the downstream end of the nicotine pod assembly 300 presses against the first downstream projection 130a and the second downstream projection 130b of the retaining structure 140. As a result, the first downstream projection 130a and the second downstream projection 130b of the retaining structure 140 elastically yield and retract from the through-hole 150 of the device body 100 (by compression of the first spring 144a and the second spring 144b), thereby allowing the insertion of the nicotine pod assembly 300 to proceed. In an exemplary embodiment, when the first downstream projection 130a and the second downstream projection 130b are fully retracted from the through-hole 150 of the device body 100, the displacement of the retaining structure 140 may cause the ends of the first post 142a and the second post 142b to contact the inner end face of the frame 106. Furthermore, since the mouthpiece 102 is connected to the retaining structure 140, the distal end of the mouthpiece 102 retracts from the through hole 150, and therefore the proximal end of the mouthpiece 102 (e.g., the visible portion including the end cover 138) also shifts away from the device housing by a corresponding distance.
[0054] When the nicotine pod assembly 300 is properly inserted so that the first downstream recess and the second downstream recess of the nicotine pod assembly 300 reach a position that allows engagement with the first downstream projection 130a and the second downstream projection 130b, respectively, the energy stored from the compression of the first spring 144a and the second spring 144b causes the first downstream projection 130a and the second downstream projection 130b to elastically extend and engage with the first downstream recess and the second downstream recess of the nicotine pod assembly 300. Furthermore, the engagement may generate tactile and / or auditory feedback (e.g., an audible click) to inform the adult e-vaping device user that the nicotine pod assembly 300 is properly positioned within the through-hole 150 of the device body 100.
[0055] Figure 16 is a partially exploded view relating to the front cover, frame, and rear cover of Figure 14. Referring to Figure 16, various mechanical components, electronic components, and / or circuits related to the operation of the nicotine e-vaping device 500 may be fixed to the frame 106. The front cover 104 and the rear cover 108 may be configured to engage with the frame 106 via snap-fit ββarrangements. In exemplary embodiments, the front cover 104 and the rear cover 108 include clips configured to interlock with corresponding mating members of the frame 106. The clips may be in the form of tabs having orifices configured to receive corresponding mating members of the frame 106 (e.g., projections with inclined edges). In Figure 16, the front cover 104 has two rows with four clips each (a total of eight clips for the front cover 104). Similarly, the rear cover 108 has two rows with four clips each (a total of eight clips for the rear cover 108). The corresponding mating member of frame 106 may be located on the inner side wall of frame 106. As a result, the engaged clips and mating members may be hidden from view when the front cover 104 and rear cover 108 are snapped together. Alternatively, the front cover 104 and / or rear cover 108 may be configured to engage with frame 106 via a press-fit. However, naturally, the front cover 104, frame 106, and rear cover 108 may be connected by other suitable arrangements and techniques.
[0056] Figure 17 is a perspective view of the nicotine pod assembly of the nicotine e-vaping device of Figure 6. Figure 18 is another perspective view of the nicotine pod assembly of Figure 17. Figure 19 is another perspective view of the nicotine pod assembly of Figure 18. Referring to Figures 17-19, the nicotine pod assembly 300 for the nicotine e-vaping device 500 includes a pod body configured to hold a nicotine pre-vapor formulation. The pod body has an upstream end and a downstream end. The upstream end of the pod body defines a pod inlet 322. The downstream end of the pod body defines a pod outlet 304 which is in fluid communication with the pod inlet 322 at the upstream end. During vaping, air enters the nicotine pod assembly 300 through the pod inlet 322 and nicotine vapor exits the nicotine pod assembly 300 through the pod outlet 304. The pod inlet 322 is shown in the drawing as being in the form of a slot. However, naturally, the exemplary embodiments are not limited to these, and other forms are also possible.
[0057] The nicotine pod assembly 300 includes a connector module 320 (e.g., Figure 21) located within the pod body and exposed by an opening at its upstream end. The outer surface of the connector module 320 includes at least one electrical contact. The at least one electrical contact may include a plurality of power contacts. For example, the plurality of power contacts may include a first power contact 324a and a second power contact 324b. The first power contact 324a of the nicotine pod assembly 300 is configured to electrically connect to a first power contact of the device electrical connector 132 of the device body 100 (e.g., the power contact adjacent to the first upstream projection 128a in Figure 12). Similarly, the second power contact 324b of the nicotine pod assembly 300 is configured to electrically connect to a second power contact of the device electrical connector 132 of the device body 100 (e.g., the power contact adjacent to the second upstream projection 128b in Figure 12). Furthermore, at least one electrical contact of the nicotine pod assembly 300 includes a plurality of data contacts 326. The plurality of data contacts 326 of the nicotine pod assembly 300 are configured to electrically connect to the data contacts of the device electrical connector 132 (e.g., the five rows of protrusions in Figure 12). While two power contacts and five data contacts are shown in relation to the nicotine pod assembly 300, other variations are, of course, possible depending on the design of the device body 100.
[0058] In exemplary embodiments, the nicotine pod assembly 300 includes a front surface, a rear surface opposite the front surface, a first side surface between the front and rear surfaces, a second side surface opposite the first side surface, an upstream end surface, and a downstream end surface opposite the upstream end surface. The corners of the side surfaces and end surfaces (e.g., the corner between the first side surface and the upstream end surface, the corner between the upstream end surface and the second side surface, the corner between the second side surface and the downstream end surface, and the corner between the downstream end surface and the first side surface) may be rounded. However, in some examples, the corners may be angular. Furthermore, the peripheral edge of the front surface may be in the form of a ledge. The outer surface of the connector module 320 (exposed by the pod body) may be considered part of the upstream end surface of the nicotine pod assembly 300. The front surface of the nicotine pod assembly 300 may be wider and longer than the rear surface. In such examples, the first and second side surfaces may be angled inward toward each other. The upstream and downstream end surfaces may also be angled inward toward each other. Due to the angled surface, insertion of the nicotine pod assembly 300 is unidirectional (for example, from the front side of the device body 100 (the side associated with the front cover 104)). As a result, the possibility of the nicotine pod assembly 300 being improperly inserted into the device body 100 can be reduced or prevented.
[0059] As shown in the figure, the pod body of the nicotine pod assembly 300 includes a first housing section 302 and a second housing section 308. The first housing section 302 has a downstream end that defines a pod outlet 304. The edge of the pod outlet 304 may optionally be a recessed or indented area. In such examples, this area may resemble a cove, and the side of the edge adjacent to the rear surface of the nicotine pod assembly 300 may be open, while the side of the edge adjacent to the front surface may be enclosed by a raised portion at the downstream end of the first housing section 302. The raised portion may function as a stopper for the distal end of the mouthpiece 102. As a result, this configuration of the pod outlet 304 may facilitate the reception and alignment of the distal end of the mouthpiece 102 (e.g., Figure 11) via the seating of the open side of the edge and the subsequent raised portion at the downstream end of the first housing section 302. In a non-limiting embodiment, the distal end of the mouthpiece 102 may also include (or be formed of) an elastic material that helps to create a seal around the pod outlet 304 when the nicotine pod assembly 300 is properly inserted into the through hole 150 of the device body 100.
[0060] The downstream end of the first housing section 302 further defines at least one downstream recess. In exemplary embodiments, at least one downstream recess is in the form of a first downstream recess 306a and a second downstream recess 306b. The pod outlet 304 may be located between the first downstream recess 306a and the second downstream recess 306b. The first downstream recess 306a and the second downstream recess 306b are configured to engage with a first downstream projection 130a and a second downstream projection 130b of the device body 100, respectively. As shown in Figure 11, the first downstream projection 130a and the second downstream projection 130b of the device body 100 may be located at adjacent corners of the downstream side wall of the through hole 150. The first downstream recess 306a and the second downstream recess 306b may each be in the form of a V-shaped notch. In such examples, each of the first downstream projection 130a and the second downstream projection 130b of the device body 100 may be in the form of a wedge-shaped structure configured to engage with corresponding V-shaped notches in the first downstream recess 306a and the second downstream recess 306b. The first downstream recess 306a may abut against the corner of the downstream end face and the first side surface, and the second downstream recess 306b may abut against the corner of the downstream end face and the second side surface. As a result, the edges of the first downstream recess 306a and the second downstream recess 306b adjacent to the first side surface and the second side surface, respectively, may be open. In such examples, as shown in Figure 18, each of the first downstream recess 306a and the second downstream recess 306b may be a three-sided recess.
[0061] The second housing section 308 has an upstream end that further defines a number of openings (e.g., a first power contact opening 325a, a second power contact opening 325b, and a data contact opening 327) configured to expose the connector module 320 (Figures 20-21) within the nicotine pod assembly 300 (in addition to the pod inlet 322). The upstream end of the second housing section 308 also defines at least one upstream recess. In exemplary embodiments, at least one upstream recess is in the form of a first upstream recess 312a and a second upstream recess 312b. The pod inlet 322 may be located between the first upstream recess 312a and the second upstream recess 312b. The first upstream recess 312a and the second upstream recess 312b are configured to engage with the first upstream projection 128a and the second upstream projection 128b of the device body 100, respectively. As shown in Figure 12, the first upstream projection 128a and the second upstream projection 128b of the device body 100 may be located at adjacent corners of the upstream side wall of the through hole 150. The depth of the first upstream recess 312a and the second upstream recess 312b may be greater than the depth of the first downstream recess 306a and the second downstream recess 306b. The ends of the first upstream recess 312a and the second upstream recess 312b may also be more rounded than the ends of the first downstream recess 306a and the second downstream recess 306b. For example, the first upstream recess 312a and the second upstream recess 312b may each be in the form of a U-shaped recess. In such examples, each of the first upstream projection 128a and the second upstream projection 128b of the device body 100 may be in the form of a rounded knob configured to engage with the corresponding U-shaped recesses of the first upstream recess 312a and the second upstream recess 312b. The first upstream recess 312a may abut against the corner of the upstream end face and the first side surface, and the second upstream recess 312b may abut against the corner of the upstream end face and the second side surface. As a result, the edges of the first upstream recess 312a and the edge of the second upstream recess 312b adjacent to the first and second side surfaces, respectively, may be open.
[0062] The first housing section 302 may define an internal storage section configured to hold the nicotine pre-vapor formulation. The storage section may be configured to seal the nicotine pre-vapor formulation until the activation of the nicotine pod assembly 300 to release the nicotine pre-vapor formulation from the storage section. As a result of the airtight seal, the nicotine pre-vapor formulation is separated from the environment and internal elements of the nicotine pod assembly 300 that may react with the nicotine pre-vapor formulation, thereby reducing or preventing the possibility of adverse effects on the shelf life and / or perceptual properties (e.g., flavor) of the nicotine pre-vapor formulation. The second housing section 308 may include a structure configured to activate the nicotine pod assembly 300 and, after activation, receive and heat the nicotine pre-vapor formulation released from the storage section.
[0063] The nicotine pod assembly 300 may be manually activated by an adult e-vaping device user before inserting the nicotine pod assembly 300 into the device body 100. Alternatively, the nicotine pod assembly 300 may be activated as part of the insertion of the nicotine pod assembly 300 into the device body 100. In an exemplary embodiment, the second housing section 308 of the pod body includes a puncture device configured to release a nicotine pre-vapor formulation from a storage section in the first housing section 302 during the activation of the nicotine pod assembly 300. The puncture device may be in the form of a first activation pin 314a and a second activation pin 314b, which are described in more detail herein.
[0064] To manually activate the nicotine pod assembly 300, an adult e-vaping device user may first push the first activation pin 314a and the second activation pin 314b inward (e.g., simultaneously or sequentially) before inserting the nicotine pod assembly 300 into the through-hole 150 of the device body 100. For example, the first activation pin 314a and the second activation pin 314b may be pushed manually until their ends are substantially level with the upstream end face of the nicotine pod assembly 300. In an exemplary embodiment, the inward movement of the first activation pin 314a and the second activation pin 314b punctures or otherwise impairs the seal of the storage compartment, thereby releasing the nicotine pre-vapor formulation therefrom.
[0065] Alternatively, in order to activate the nicotine pod assembly 300 as part of the insertion into the device body 100, the nicotine pod assembly 300 is first positioned such that the first upstream recess 312a and the second upstream recess 312b engage with the first upstream projection 128a and the second upstream projection 128b, respectively (e.g., upstream engagement). Since each of the first upstream projection 128a and the second upstream projection 128b of the device body 100 may be in the form of a rounded knob configured to engage with the corresponding U-shaped recesses of the first upstream recess 312a and the second upstream recess 312b, the nicotine pod assembly 300 can then be relatively easily swung into the through-hole 150 of the device body 100 around the first upstream projection 128a and the second upstream projection 128b.
[0066] With respect to the rotation of the nicotine pod assembly 300, the axis of rotation can be considered to extend through the first upstream projection 128a and the second upstream projection 128b and be oriented perpendicular to the longitudinal axis of the device body 100. During the initial positioning and subsequent rotation of the nicotine pod assembly 300, the first activation pin 314a and the second activation pin 314b are in contact with the upstream side wall of the through hole 150, and as the nicotine pod assembly 300 advances into the through hole 150, the first activation pin 314a and the second activation pin 314b are pushed into the second housing section 308 (for example, simultaneously), transitioning from an extended state to a retracted state. When the downstream end of the nicotine pod assembly 300 reaches the vicinity of the downstream side wall of the through hole 150 and contacts the first downstream projection 130a and the second downstream projection 130b, the first downstream projection 130a and the second downstream projection 130b retract and then elastically extend (e.g., downstream engagement) when the positioning of the nicotine pod assembly 300 allows the first downstream projection 130a and the second downstream projection 130b of the device body 100 to engage with the first downstream recess 306a and the second downstream recess 306b of the nicotine pod assembly 300, respectively.
[0067] As described above, according to exemplary embodiments, the mouthpiece 102 is fixed to the retaining structure 140 (the first downstream projection 130a and the second downstream projection 130b being part of this structure). In such examples, the retraction of the first downstream projection 130a and the second downstream projection 130b from the through-hole 150 results in a simultaneous shift of the mouthpiece 102 by a corresponding distance in the same direction (e.g., downstream). Conversely, when the nicotine pod assembly 300 is fully inserted to facilitate downstream engagement, the mouthpiece 102 springs back simultaneously with the first downstream projection 130a and the second downstream projection 130b. In addition to the elastic engagement by the first downstream projection 130a and the second downstream projection 130b, the distal end of the mouthpiece 102 is also configured to be biased against the nicotine pod assembly 300 (and aligned with the pod outlet 304 to form a relatively vapor-tight seal) when the nicotine pod assembly 300 is properly positioned within the through-hole 150 of the device body 100.
[0068] Furthermore, the downstream engagement may generate an audible click and / or tactile feedback indicating that the nicotine pod assembly 300 is properly seated within the through-hole 150 of the device body 100. When properly seated, the nicotine pod assembly 300 is mechanically, electrically, and fluidly connected to the device body 100. While non-limiting embodiments of this specification describe the upstream engagement of the nicotine pod assembly 300 occurring before the downstream engagement, the associated mating, starting, and / or electrical arrangements may, of course, be reversed so that the downstream engagement occurs before the upstream engagement.
[0069] Figure 20 is a partially exploded view of the nicotine pod assembly of Figure 19. Referring to Figure 20, the first housing section 302 includes a vapor channel 316. The vapor channel 316 is configured to receive nicotine vapor generated during vaping and is in fluid communication with the pod outlet 304. In exemplary embodiments, the size (e.g., diameter) of the vapor channel 316 may gradually increase as it extends toward the pod outlet 304. Furthermore, the vapor channel 316 may be formed integrally with the first housing section 302. The insert 342 and seal 344 are located at the upstream end of the first housing section 302 to define the storage portion of the nicotine pod assembly 300. For example, the insert 342 may be placed within the first housing section 302 such that the peripheral surface of the insert 342 engages with the inner surface of the first housing section 302 along its edge (e.g., via a press-fit), such that the interface between the peripheral surface of the insert 342 and the inner surface of the first housing section 302 is fluid-tight (e.g., liquid-tight and / or airtight). Furthermore, the seal 344 may be attached to the upstream side of the insert 342 to seal the outlet of the storage section of the insert 342, providing fluid-tight (e.g., liquid-tight and / or airtight) containment of the nicotine prevapor formulation into the storage section. The insert 342 and the seal 344 are also illustrated, for example, in Figure 24 and are described in more detail herein.
[0070] The upstream end of the second housing section 308 defines a pod inlet 322, a first power contact opening 325a, a second power contact opening 325b, a data contact opening 327, a first upstream recess 312a, a second upstream recess 312b, a first pin opening 315a, and a second pin opening 315b. As described above, the pod inlet 322 allows air to enter the nicotine pod assembly 300 during vaping, and the first power contact opening 325a, the second power contact opening 325b, and the data contact opening 327 are configured to expose the first power contact 324a, the second power contact 324b, and the data contact 326 of the connector module 320, respectively. In an exemplary embodiment, the first power contact 324a and the second power contact 324b are mounted on the module housing 354 of the connector module 320. Furthermore, the data contact 326 may be located on a printed circuit board (PCB) 362. Additionally, the pod inlet 322 may be located between the first upstream recess 312a and the second upstream recess 312b, and the contact openings (e.g., the first power contact opening 325a, the second power contact opening 325b, and the data contact opening 327) may be located between the first pin opening 315a and the second pin opening 315b. The first pin opening 315a and the second pin opening 315b are configured to accommodate the first activation pin 314a and the second activation pin 314b, respectively, extending through them.
[0071] Figure 21 is a perspective view of the connector module of Figure 20. Figure 22 is another perspective view of the connector module of Figure 21. Referring to Figures 21-22, the general framework of the connector module 320 includes a module housing 354. Furthermore, the connector module 320 has multiple surfaces, including an outer surface and sides adjacent to the outer surface. In an exemplary embodiment, the outer surface of the connector module 320 consists of the upstream surface of the module housing 354, a first power contact 324a, a second power contact 324b, a data contact 326, and a printed circuit board (PCB) 362. The sides of the connector module 320 are integral parts of the module housing 354 and may be substantially perpendicular to the outer surface.
[0072] The nicotine pod assembly 300 defines a flow path internally from the pod inlet 322 to the pod outlet 304. The flow path through the nicotine pod assembly 300 includes, among other things, a first branching section, a second branching section, and a merging section. The pod inlet 322 is upstream of the first and second branching sections of the flow path. In particular, as shown in Figure 21, the side of the module housing 354 (and connector module 320) above the first power contact 324a and the second power contact 324b (e.g., the inlet side) is recessed to define a partition 329, along with the initial segments of the first and second branching sections of the flow path. In an exemplary embodiment where the partition 329 is recessed from the outer surface of the module housing 354 (for example, Figure 21), the side of the module housing 354 above the first power contact 324a and the second power contact 324b can also be considered to define the inlet portion of the flow path downstream of the pod inlet 322 and upstream of the first and second branch portions of the flow path.
[0073] The pair of longer sides (e.g., vertical sides) of the module housing 354 are also recessed to define the subsequent segments of the first and second branch portions of the flow path. Hereinafter, the pair of longer sides of the module housing 354 may be alternatively referred to as the lateral sides. The sector of the module housing 354 covered by the printed circuit board (PCB) 362 (shown in Figure 30), along with the confluence portion of the flow path, defines further segments of the first and second branch portions. These further segments of the first and second branch portions include, respectively, a first curved segment (e.g., the first curved path 330a) and a second curved segment (e.g., the second curved path 330b). As will be described in more detail herein, the first and second branch portions merge to form the confluence portion of the flow path.
[0074] When the connector module 320 is placed in the receptive cavity downstream of the second housing section 308, the non-recessed side of the module housing 354 interfaces with the side wall of the receptive cavity of the second housing section 308, and the recessed side of the module housing 354, together with the side wall of the receptive cavity, defines the first and second branch portions of the flow path. The seating of the connector module 320 in the receptive cavity of the second housing section 308 may be via a tightly fitting arrangement such that the connector module 320 remains essentially fixed within the nicotine pod assembly 300.
[0075] As shown in Figure 22, the connector module 320 includes a wick 338 configured to transmit a nicotine prevapor formulation to a heater 336. The heater 336 is configured to heat the nicotine prevapor formulation during vaping to generate nicotine vapor. The heater 336 is electrically connected to at least one electrical contact of the connector module 320. For example, one end of the heater 336 (e.g., the first end) may be connected to a first power contact 324a, and the other end of the heater 336 (e.g., the second end) may be connected to a second power contact 324b. In exemplary embodiments, the heater 336 includes a folded heating element. In such examples, the wick 338 may have a planar shape configured to be held by the folded heating element. When the nicotine pod assembly 300 is assembled, the wick 338 is configured to be in fluid communication with the absorbent material 346 (e.g., Figure 25) so that the nicotine prevapor formulation, which will be contained within the absorbent material 346, is transmitted to the wick 338 via capillary action (when the nicotine pod assembly 300 is activated).
[0076] In an exemplary embodiment, the airflow entering the nicotine pod assembly 300 through the pod inlet 322 is directed by a partition 329 to a first branch and a second branch of the flow path. The partition 329 may be wedge-shaped and may be configured to split the incoming airflow in opposite directions (e.g., at least initially). The split airflow may include a first airflow (moving through the first branch of the flow path) and a second airflow (moving through the second branch of the flow path). After splitting by the partition 329, the first airflow continues along the inlet side, around the corner, along the first lateral surface, into a first curved path 330a. Similarly, the second airflow continues along the inlet side, around the corner, along the second lateral surface, into the first curved path 330b (e.g., Figure 30). The confluence of the flow paths is located downstream of the first and second branch sections. The heater 336 and core 338 are located downstream of the confluence of the flow paths. Thus, the first airflow combines with the second airflow at the confluence of the flow paths (e.g., the confluence path 330c in Figure 30) to form a combined flow before passing through the module outlet 368 of the module housing 354 (e.g., labeled in Figure 28) to the heater 336 and core 338.
[0077] Figure 23 is an exploded view relating to the wick and heater of Figure 22. Referring to Figure 23, the wick 338 may be a fibrous pad or other structure having voids / gaps designed for capillary action. Furthermore, the wick 338 may have a rectangular shape, but exemplary embodiments are not limited thereto. For example, the wick 338 may have an alternative irregular hexagonal shape, with two sides angled inward toward the heater 336. The wick 338 may be fabricated into a desired shape or cut into such a shape from a larger sheet material. If the lower section of the wick 338 is tapered toward the winding section of the heater 336 (e.g., hexagonal shape), the possibility of the nicotine prevapor formulation becoming part of the wick 338 and avoiding continuous vaporization (due to its distance from the heater 336) is reduced or avoided. Furthermore, as described above, the heater 336 may include a folded heating element configured to grip the wick 338. The folded heating element may also include at least one prong 337 configured to protrude into the wick 338.
[0078] In exemplary embodiments, the heater 336 may be configured to undergo Joule heating (also known as Ohm / resistive heating) when an electric current is applied. More specifically, the heater 336 may be made of one or more conductors (resistive materials) and configured to generate heat when an electric current is passed through it. The electric current may be supplied from a power source (e.g., a battery) within the apparatus body 100 and delivered to the heater 336 via a first power contact 324a or a second power contact 324b.
[0079] Suitable conductors (resistive materials) for the heater 336 include iron-based alloys (e.g., stainless steel) and / or nickel-based alloys (e.g., nichrome). The heater 336 may be made from a conductive sheet (e.g., metal, alloy) stamped to cut a winding pattern from it. The winding pattern may have curved segments arranged alternately with horizontal segments such that the horizontal segments extend parallel to each other while simultaneously zigzagging back and forth. Furthermore, the width of each horizontal segment of the winding pattern may be substantially equal to the spacing between adjacent horizontal segments of the winding pattern, but exemplary embodiments are not limited thereto. To obtain the form of the heater 336 shown in the drawings, the winding pattern may be folded to grip the core 338. Furthermore, if a prong 337 is part of the heater 336, the projection corresponding to the prong 337 is bent (e.g., inward and / or perpendicular) before the winding pattern is folded. As a result of the prong 337, the possibility of the core 338 coming out of the heater 336 is reduced or prevented. The heater and related structures are described in detail in U.S. Patent Application No. 15 / 729,909, filed on 11 October 2017, entitled βFolded Heater For Electronic Vaping Devic,β which is incorporated herein by reference in its entirety.
[0080] Figure 24 is an exploded view relating to the first housing section of the nicotine pod assembly of Figure 17. Referring to Figure 24, the first housing section 302 includes a vapor channel 316. The vapor channel 316 is configured to receive nicotine vapor generated by the heater 336 and is in fluid communication with the pod outlet 304. In exemplary embodiments, the size (e.g., diameter) of the vapor channel 316 may gradually increase as it extends toward the pod outlet 304. Furthermore, the vapor channel 316 may be formed integrally with the first housing section 302. The insert 342 and seal 344 are located at the upstream end of the first housing section 302 to define the storage portion of the nicotine pod assembly 300. For example, insert 342 may be placed within the first housing section 302 such that the peripheral surface of insert 342 engages with the inner surface of the first housing section 302 along its edge (e.g., via a press-fit) such that the interface between the peripheral surface of insert 342 and the inner surface of the first housing section 302 is fluid-tight (e.g., liquid-tight and / or airtight). Furthermore, seal 344 may be attached to the upstream side of insert 342 to seal the outlet of the storage section of insert 342, providing fluid-tight (e.g., liquid-tight and / or airtight) containment of the nicotine prevapor formulation into the storage section. Hereinafter, the first housing section 302, insert 342, and seal 344 may be collectively referred to as the first section. As will be described in more detail herein, the first section is configured to seal the nicotine prevapor formulation until the nicotine pod assembly 300 is activated.
[0081] In an exemplary embodiment, the insert 342 includes a holder portion protruding from the upstream side (shown in Figure 24) and a connector portion protruding from the downstream side (hidden in Figure 24). The holder portion of the insert 342 is configured to hold an absorbent material 346 (e.g., Figure 25), and the connector portion of the insert 342 is configured to engage with the vapor channel 316 of the first housing section 302. The connector portion of the insert 342 may be positioned within the vapor channel 316 and therefore configured to engage with the interior of the vapor channel 316. Alternatively, the connector portion of the insert 342 may be configured to receive the vapor channel 316 and therefore engage with the exterior of the vapor channel 316. The insert 342 also defines a storage outlet through which the nicotine pre-vapor formulation flows when the seal 344 is punctured during the activation of the nicotine pod assembly 300. The holder portion and connector portion of insert 342 may be located between the storage outlets (e.g., a first storage outlet and a second storage outlet), but exemplary embodiments are not limited thereto. Furthermore, insert 342 defines vapor conduits extending through the holder portion and connector portion. As a result, when insert 342 is placed in the first housing section 302, the vapor conduits of insert 342 are aligned with and in fluid communication with the vapor channel 316, such that a continuous path is formed for nicotine vapor generated by the heater 336 during vaping, passing through the storage and through to the pod outlet 304.
[0082] The seal 344 is mounted upstream of the insert 342 so as to cover the storage outlet of the insert 342. In an exemplary embodiment, the seal 344 defines an opening (e.g., a central opening) configured to provide a suitable gap to accommodate the holder portion (protruding from the upstream side of the insert 342) when the seal 344 is mounted on the insert 342. When the seal 344 is perforated by the first activation pin 314a and the second activation pin 314b of the nicotine pod assembly 300, the two perforated sections of the seal 344 are pushed into the storage as flaps, thus creating two perforated openings within the seal 344 (e.g., one on each side of the central opening). The size and shape of the perforated openings in the seal 344 may correspond to the size and shape of the storage outlet of the insert 342. In contrast, in the unperforated state as shown in Figure 24, the seal 344 has a planar shape and only one opening (e.g., a central opening). The seal 344 is designed to be strong enough to remain intact so as not to be torn prematurely or accidentally during normal transport and / or handling of the nicotine pod assembly 300. For example, the seal 344 may be a coated foil (e.g., polyethylene terephthalate (PET) backed with aluminum).
[0083] Figure 25 is a partially exploded view relating to the second housing section of the nicotine pod assembly of Figure 17. Referring to Figure 25, the second housing section 308 is structured to contain various components configured to release, receive, and heat the nicotine prevapor formulation. For example, the first activation pin 314a and the second activation pin 314b are configured to puncture the storage section of the first housing section 302 to release the nicotine prevapor formulation. Each of the first activation pin 314a and the second activation pin 314b has a distal end that extends through the corresponding one of the first pin openings 315a and the second pin opening 315b of the second housing section 308. In exemplary embodiments, the distal ends of the first activation pin 314a and the distal ends of the second activation pin 314b are visible after assembly (e.g., Figure 17), while the rest of the first activation pin 314a and the second activation pin 314b are hidden from view within the nicotine pod assembly 300. Furthermore, each of the first activation pin 314a and the second activation pin 314b has a proximal end positioned adjacent to and upstream of the seal 344 before activation of the nicotine pod assembly 300. When the first activation pin 314a and the second activation pin 314b are pushed into the second housing section 308 to activate the nicotine pod assembly 300, the proximal ends of each of the first activation pin 314a and the second activation pin 314b advance through the insert 342, thereby perforating the seal 344 and releasing the nicotine prevapor formulation from the storage section. The movement of the first activation pin 314a may be independent of the movement of the second activation pin 314b (and vice versa). The first activation pin 314a and the second activation pin 314b are described in more detail herein.
[0084] The absorbent material 346 may be placed within a holder (e.g., an upper hat holder 345). The absorbent material 346 is also located downstream of the core 338 and is in fluid communication with the core 338. Furthermore, as described above, the absorbent material 346 is configured to engage with the holder portion of the insert 342 (protruding from the upstream side of the insert 342, as shown in Figure 24). The absorbent material 346 may have an annular shape, but exemplary embodiments are not limited thereto. As shown in Figure 25, the absorbent material 346 may resemble a hollow cylindrical shape. In such examples, the outer diameter of the absorbent material 346 may be substantially equal to (or slightly larger than) the length of the core 338. The inner diameter of the absorbent material 346 may be smaller than the average outer diameter of the holder portion of the insert 342 to provide an interlocking fit. To facilitate engagement with the absorbent material 346, the tip of the holder portion of the insert 342 may be tapered. The absorbent material 346 is configured to receive and retain the amount of nicotine prevapor formulation released from the storage unit when the nicotine pod assembly 300 is activated.
[0085] The wick 338 is positioned within the nicotine pod assembly 300 to be in fluid communication with the absorbent material 346 so that the nicotine prevapor formulation can be drawn out from the absorbent material 346 to the heater 336 via capillary action. The wick 338 may be in physical contact with the upstream side of the absorbent material 346 (for example, the bottom of the absorbent material 346, based on the diagram shown in Figure 25). Furthermore, the wick 338 may be aligned with the diameter of the absorbent material 346, but exemplary embodiments are not limited thereto.
[0086] As shown in Figure 25 (and Figure 23 above), the heater 336 may have a folded configuration to grip the opposing surfaces of the wick 338 and establish thermal contact with the wick 338. The heater 336 is configured to heat the wick 338 during vaping to produce nicotine vapor. To facilitate such heating, the first end of the heater 336 may be electrically connected to the first power contact 324a, and the second end of the heater 336 may be electrically connected to the second power contact 324b. As a result, current may be supplied from a power source (e.g., a battery) within the device body 100 and delivered to the heater 336 via the first power contact 324a or the second power contact 324b. Relevant details of other embodiments of the connector module 320 already described above (for example, in relation to Figures 21-22) are not repeated in this section for the sake of brevity. In exemplary embodiments, although hidden in Figure 25, the second housing section 308 includes a receiving cavity for the connector module 320. The second housing section 308 and the internal components described above may be collectively referred to as the second section. During vaping, the nicotine vapor generated by the heater 336 passes through the vapor conduit of the insert 342, through the vapor channel 316 of the first housing section 302, exits the pod outlet 304 of the nicotine pod assembly 300, and is drawn out through the vapor passage 136 of the mouthpiece 102 to the vapor outlet.
[0087] Figure 26 is an exploded view of the upper hat holder of Figure 25. Referring to Figure 26, the upper hat holder 345 includes a base portion 345a and a cylindrical portion 345b. In exemplary embodiments, the base portion 345a and the cylindrical portion 345b are integrally formed. The cylindrical portion 345b defines a well configured to receive an absorbent material 346. Optionally, the inner lower surface of the well may include a ledge (or other projection) to support the absorbent material 346 so that it does not simply pass through the upper hat holder 345 or sag from the upper hat holder 345 (for example, when the absorbent material 346 is saturated with a nicotine pre-vapor formulation released from the storage portion). Furthermore, the base portion 345a defines a groove configured to receive a gasket 345c. Furthermore, a pair of integrally formed posts may extend from the base portion 345a and along the outside of the cylindrical portion 345b so as to protrude beyond the edge of the cylindrical portion 345b. When the upper hat holder 345 is assembled within the nicotine pod assembly 300, these pairs of integrally formed posts may abut against the underside of the insert 342 by a portion of the seal 344 between them.
[0088] Figure 27 is an exploded view of the activation pin of Figure 25. Referring to Figure 27, the activation pin may be in the form of a first activation pin 314a and a second activation pin 314b. Although two activation pins are shown and described in relation to the non-limiting embodiments of this specification, naturally, alternatively, the nicotine pod assembly 300 may include only one activation pin. In Figure 27, the first activation pin 314a may include a first blade 348a, a first actuator 350a, and a first O-ring 352a. Similarly, the second activation pin 314b may include a second blade 348b, a second actuator 350b, and a second O-ring 352b.
[0089] In exemplary embodiments, the first blade 348a and the second blade 348b are integrally formed with the first actuator 350a and the second actuator 350b, respectively. Alternatively, the first blade 348a and the second blade 348b may be configured to be mounted or attached to the upper portions (e.g., proximal portions) of the first actuator 350a and the second actuator 350b, respectively. Mounting or attachment can be achieved via snap-fit ββconnections, interlocking (e.g., friction-fit) connections, adhesives, or other suitable bonding techniques. The upper portions of each of the first blade 348a and the second blade 348b may have one or more curved or concave edges that taper upward toward a pointed tip. For example, each of the first blade 348a and the second blade 348b may have two pointed tips with a concave edge between them, and a curved edge adjacent to each pointed tip. The radii of curvature of the concave edge and the curved edge may be the same, and their arc lengths may differ. The first blade 348a and the second blade 348b may be formed from sheet metal (e.g., stainless steel) that has a desired profile and is cut or shaped to bend into its final form. In another example, the first blade 348a and the second blade 348b may be formed from plastic (e.g., when formed integrally with the first actuator 350a and the second actuator 350b).
[0090] The size and shape of the first blade 348a, the second blade 348b, and the first actuator 350a and the second actuator 350b may correspond to the size and shape of the storage outlet of the insert 342, based on a plan view in which they are integrally formed (or mounted). Furthermore, as shown in Figure 27, the first and second activation pins 314a and 314b may include protruding edges (e.g., curved inner lips facing each other) configured to push the two perforated sections of the seal 344 into the storage as the first and second blades 348a and 348b advance into the storage. In a non-limiting embodiment, when the first activation pin 314a and the second activation pin 314b are fully inserted into the nicotine pod assembly 300, the two flaps (from the two perforated sections of the seal 344) may be located between the curved side wall of the storage outlet of the insert 342 and the corresponding curves of the protruding edges of the first activation pin 314a and the second activation pin 314b. As a result, the possibility of obstruction of the two perforated openings of the seal 344 (by the two flaps from the two perforated sections) can be reduced or prevented. Furthermore, the first activation pin 314a and the second activation pin 314b may be configured to guide the nicotine prevapor formulation from the storage towards the absorbent material 346 in the upper hat holder 345.
[0091] The lower portion (e.g., distal portion) of each of the first actuator 350a and the second actuator 350b is configured to extend through the bottom section (e.g., upstream end) of the second housing section 308. This rod-like portion of each of the first actuator 350a and the second actuator 350b may also be called a shaft. The first O-ring 352a and the second O-ring 352b may be placed in the annular grooves of the respective shafts of the first actuator 350a and the second actuator 350b. The first O-ring 352a and the second O-ring 352b are configured to engage with the shafts of the first actuator 350a and the second actuator 350b, as well as the inner surfaces of the corresponding openings of the second housing section 308, in order to provide a fluid-tight seal. As a result, when the first activation pin 314a and the second activation pin 314b are pushed inward to activate the nicotine pod assembly 300, the first O-ring 352a and the second O-ring 352b move together with the respective shafts of the first actuator 350a and the second actuator 350b within the corresponding openings of the second housing section 308, while maintaining their respective seals, thereby helping to reduce or prevent leakage of the nicotine pre-vapor formulation through the openings of the second housing section 308 to the first activation pin 314a and the second activation pin 314b. The first O-ring 352a and the second O-ring 352b may be formed of silicone.
[0092] The puncturer for the nicotine pod assembly 300 may include notches configured to engage with a clip to prevent premature operation of the puncturer. For example, the shafts of the first activation pin 314a and the second activation pin 314b may define a first notch 351a and a second notch 351b, respectively, configured to engage with such a clip. In an exemplary embodiment, the clip may be a planar structure defining a first slot and a second slot, respectively, configured to engage with the first notch 351a and the second notch 351b. When engaged with the shafts of the first activation pin 314a and the second activation pin 314b (through the first notch 351a and the second notch 351b, respectively), the clip may be adjacent to the second housing section 308, thereby preventing the first activation pin 314a and / or the second activation pin 314b from being inadvertently pushed into the nicotine pod assembly 300. As a result, the first activation pin 314a and the second activation pin 314b may be appropriately restrained (e.g., during shipping and / or handling) to reduce or prevent the possibility of their premature activation. The clip may be removed (e.g., by an adult e-vaping device user) at the appropriate time when the nicotine pod assembly 300 is activated.
[0093] Figure 28 is a perspective view of the connector module of Figure 22, excluding the wick and heater. Figure 29 is an exploded view of the connector module of Figure 28. Figure 30 is another exploded view of the connector module of Figure 28. Referring to Figures 28-30, the module housing 354 forms the framework of the connector module 320. The module housing 354 defines, among other things, the partition 329 and the passage for air drawn into the nicotine pod assembly 300. When assembled within the nicotine pod assembly 300, the downstream edge of the module housing 354 may engage with the upstream edge of the base portion 345a of the upper hat holder 345 (e.g., Figure 26). As a result, the heater 336 and wick 338 (e.g., Figure 22) may be (at least partially) enclosed by the module housing 354 and the upper hat holder 345. Furthermore, the internal space defined by the module housing 354 and the upper hat holder 345 can be considered a heating chamber when assembled (with the heater 336 and wick 338 placed inside it). The heating chamber is in fluid communication with the upstream flow path of the module housing 354 via the module outlet 368.
[0094] As described above, the airflow channel for the air drawn into the nicotine pod assembly 300 includes a first branching section, a second branching section, and a confluence section defined by the module housing 354. In exemplary embodiments, the first branching section and the second branching section are symmetrical sections bisected by an axis corresponding to the confluence section of the airflow channel. For example, as shown in Figure 30, the first branching section, the second branching section, and the confluence section may include a first curved path 330a, a second curved path 330b, and a confluence path 330c, respectively. The first curved path 330a and the second curved path 330b may be substantially U-shaped paths, and the confluence path 330c may be substantially straight. Based on an axis corresponding to the confluence path 330c and aligned with the top of the partition 329, the first branching section of the airflow channel may be a mirror image of the second branching section of the airflow channel. During vaping, the air drawn through the pod inlet 322 is divided by the partition 329, which first flows in opposite directions away from the partition 329, then flows parallel to each other, after which each airflow makes a U-turn (through the first curved path 330a and the second curved path 330b) and merges for a combined flow that moves back toward the partition 329 before passing through the module outlet 368 to the heating chamber (through the confluence path 330c). The heater 336 and wick 338 may be positioned so that both sides are substantially equally exposed to the airflow passing through the module outlet 368. During vaping, the generated nicotine vapor is accompanied by the airflow moving through the heating chamber to the vapor channel 316.
[0095] Partition 370 may be positioned within the module outlet 368 to divide the airflow entering the heating chamber. The heater 336 and core 338 (e.g., Figure 22) are located downstream of the module outlet 368 and may be oriented to align with partition 370. As a result of partition 370, the airflow may be divided relatively equally such that a first flow passes along the first side of the heater 336 (and core 338) and a second flow passes along the second side of the heater 336 (and core 338). In exemplary embodiments, the magnitudes (e.g., velocity, volumetric flow rate, mass flow rate) of the first and second flows may be within Β±10 percent of each other. For example, with respect to the air drawn into the heating chamber, 51 percent may be part of the first flow and 49 percent may be part of the second flow, although naturally, variations within the above range may occur. In addition to reducing flow imbalances through the heating chamber, partition 370 may also be considered a flow rectifier.
[0096] The partition 370 may be in the form of a bar extending across (e.g., bisecting) the module outlet 368. In terms of dimensions, the partition 370 may have a thickness of approximately 150β250 micrometers (e.g., 200 micrometers). The thickness of the partition 370 corresponds to the extent to which the module outlet 368 is obstructed by the partition 370. As a result, the thickness of the partition 370 and / or the size of the module outlet 368 can be adjusted to provide the desired draw resistance (e.g., 25 millimeters of water column) of the nicotine e-vaping device 500. Furthermore, the width of the partition 370 may be 525β875 micrometers (e.g., 700 micrometers). The width may be such that the partition 370 extends along most or all of the passage defined by the module outlet 368. Furthermore, assuming the module outlet 368 has a circular cross-section, the length of the partition 370 may correspond to the diameter of the module outlet 368. Alternatively, if the module exit 368 has an elliptical cross-section, the length of the partition 370 may correspond to the axes of the module exit 368 (e.g., the minor axis, the major axis).
[0097] As shown in Figures 29-30, each of the first power contact 324a and the second power contact 324b may include a contact surface and contact legs. The contact legs (which may have an elongated configuration) may be oriented perpendicular to the contact surface (which may be square), but exemplary embodiments are not limited thereto. The module housing 354 may define a pair of shallow recesses and a pair of openings to facilitate the installation of the first power contact 324a and the second power contact 324b. During assembly, the contact surfaces of each of the first power contact 324a and the second power contact 324b may be placed in the corresponding one of the pair of shallow recesses so as to be substantially coplanar with the outer surface of the module housing 354 (e.g., Figure 21). Furthermore, the contact legs of each of the first power contact 324a and the second power contact 324b may extend through the corresponding one of the pair of openings so as to project from the downstream side of the module housing 354 (e.g., Figure 28). The heater 336 may then be connected to the respective contact legs of the first power contact 324a and the second power contact 324b.
[0098] The printed circuit board (PCB) 362 includes a plurality of data contacts 326 on its upstream side (e.g., Figure 30) and various electronic components, including a sensor 364 (e.g., Figure 29), on its downstream side. The sensor 364 may be positioned on the printed circuit board (PCB) 362 such that the sensor 364 is located within a confluence path 330c defined by the module housing 354. In an exemplary embodiment, the printed circuit board (PCB) 362 (and associated components fixed thereto) is a separate structure initially inserted into a downstream receiving cavity of the second housing section 308 such that the data contacts 326 are exposed by data contact openings 327 of the second housing section 308. Subsequently, the module housing 354 (having the first power contact 324a, the second power contact 324b, the heater 336, and the attached core 338) may be inserted into the receiving cavity such that the first power contact 324a and the second power contact 324b are exposed by the first power contact opening 325a and the second power contact opening 325b of the second housing section 308, respectively. Alternatively, to simplify the above two-step insertion process into a one-step insertion process, it should be understood that printed circuit boards (PCBs) 362 (and associated components fixed thereto) may be attached to the module housing 354 (for example, to form a single integrated structure) so as to cover the first curved path 330a, the second curved path 330b, the confluence path 330c, and the module exit 368.
[0099] As described above, the module outlet 368 may also be a draw-resistance (RTD) port. In such a configuration, the draw-resistance of the nicotine e-vaping device 500 can be adjusted by changing the size of the module outlet 368 (rather than changing the size of the pod inlet 322). In exemplary embodiments, the size of the module outlet 368 may be selected so that the draw-resistance is 20 to 100 millimeters of water column (e.g., 25 to 50 millimeters of water column). For example, a 1.0 mm diameter module outlet 368 may result in a draw-resistance of 88.3 millimeters of water column. In another example, a 1.1 mm diameter module outlet 368 may result in a draw-resistance of 73.6 millimeters of water column. In yet another example, a 1.2 mm diameter module outlet 368 may result in a draw-resistance of 58.7 millimeters of water column. In yet another example, a 1.3 mm diameter module outlet 368 may result in a draw-resistance of 40 to 43 millimeters of water column. In particular, the size of the module outlet 368 is adjusted for its internal placement without affecting the external aesthetics of the nicotine pod assembly 300, thereby enabling a more standardized product design for nicotine pod assemblies with various draw resistances (RTDs), and at the same time reducing the possibility of accidental blockage of incoming air.
[0100] While numerous exemplary embodiments have been disclosed herein, it should be understood that other modifications are possible. Such modifications will not be deemed to depart from the spirit and scope of this disclosure, and all such modifications that would be obvious to those skilled in the art are intended to be included within the following claims.
