Moreover, as shown in FIG. 2, the length of the nicotine-containing e-cigarette smoking device 500 is also longer than its thickness. In addition, the width of the nicotine-containing e-cigarette smoking device 500 may be greater than its thickness. Based on the Cartesian x-y-z coordinate system, the length of the nicotine-containing e-cigarette smoking device 500 can be measured in the y direction, the width can be measured in the x direction, and the thickness can be measured in the z direction. The nicotine-containing e-cigarette smoking device 500 may have a substantially linear shape with tapered ends based on its front, side, and rear views, although exemplary embodiments are not limited to this.

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 circuitry associated with operation of the device 500 for smoking an e-cigarette containing nicotine. For example, the device housing of the device main body 100 may include a power source configured to supply power to the nicotine-containing e-cigarette smoking device 500, which may provide electrical current to the nicotine accommodating member assembly 300. In addition, when assembled, the front cover 104, frame 106, and rear cover 108 may comprise the majority of the visible portion of the device body 100. The device housing may be considered to contain all of the component parts of the device body 100 except the mouthpiece 102. In other words, the mouthpiece 102 and the device housing may be considered to form the device body 100.

The front cover 104 (e.g., the first cover) defines a primary opening configured to receive an inclined structure 112. The primary opening may have a rounded rectangular shape, although other shapes are possible depending on the shape of the inclined structure 112. The inclined structure 112 defines a through hole 150, configured to accommodate a nicotine housing assembly 300. The through hole 150 is discussed in more detail herein in conjunction with, for example, FIG. 9.

The front cover 104 also defines a secondary opening configured to accommodate a light guide arrangement. The secondary opening may resemble a groove (eg, a segmented groove), although other shapes are possible depending on the shape of the light guide arrangement. In an exemplary embodiment, the light guide arrangement includes a light guide lens 116. In addition, the front cover 104 defines a tertiary opening and a quaternary opening configured to receive a first button 118 and a second button 120.

The frame 106 (eg, the main frame) provides a central support structure for the main device portion 100 (and the nicotine e-cigarette smoking device 500 as a whole). The frame 106 may be referred to as a base. Frame 106 includes a proximal end, a distal end, and a pair of side sections between the proximal end and the distal end. The proximal end and the far end may also be referred to as the downstream end and the upstream end, respectively. As used herein, the term “near” (and conversely, “distant”) refers to an adult vaper while vaping an e-cigarette, and “downstream” (and conversely, “upstream”) refers to flow of nicotine vapor. A connecting section may be provided between opposing inner surfaces of the side sections (eg, approximately midway along the length of frame 106) for added strength and stability. The frame 106 may be formed as a single unit to be a monolithic structure.

In terms of material of construction, the frame 106 may be formed from an alloy or plastic. The alloy (eg, die-cast, machineable) may be an aluminum (Al) alloy or a zinc (Zn) alloy. The plastic may be polycarbonate (PC), acrylonitrile butadiene styrene (ABS), or a combination of both (PC/ABS). For example, the polycarbonate may be LUPOY SC1004A. In addition, the frame 106 may be provided with a surface finish for functional and/or aesthetic reasons (eg, to provide a high-quality appearance). In an exemplary embodiment, frame 106 (eg, when formed from an aluminum alloy) may be anodized. In another embodiment, the frame 106 (eg, when formed from a zinc alloy) may be hard enamel coated or painted. In another embodiment, the frame 106 (eg, when formed from polycarbonate) may be metallized. In yet another embodiment, the frame 106 (eg, when formed from acrylonitrile butadiene styrene) may have an electrolytic coating. It should be understood that the materials of construction with respect to the frame 106 may also be applicable to the front cover 104, back cover 108 and/or other relevant parts of the nicotine-containing e-cigarette smoking device 500.

The back cover 108 (e.g., the second cover) also defines an opening configured to receive the slant structure 112. The opening may have a rounded rectangular shape, although other shapes are possible depending on the shape of the slant structure 112. In an exemplary embodiment, the opening in the back cover 108 smaller than the primary opening in the front cover 104. Additionally, although not shown, it should be understood that a light guide arrangement and/or buttons may be provided at the rear of the nicotine-containing e-cigarette smoking device 500 in addition to (or instead of) the light guide arrangement and buttons them) in front of the device 500 for smoking an e-cigarette containing nicotine.

For example, the front cover 104 and/or the back cover 108 may include clips configured to interconnect with corresponding mating elements of the frame 106. In a non-limiting embodiment, the clips may be in the form of tabs with holes configured to receive corresponding mating elements (e.g., projections beveled) frame 106. Alternatively, front cover 104 and/or rear cover 108 may be configured to engage frame 106 through an interference fit (which may also be referred to as a press fit or friction fit). However, it should be understood that the front cover 104, frame 106, and back cover 108 can be connected using other suitable arrangements and techniques.

The device body 100 also includes a mouthpiece 102. The mouthpiece 102 may be attached to a proximal end of the frame 106. Additionally, as shown in FIG. 2, in an exemplary embodiment where frame 106 is sandwiched between front cover 104 and back cover 108, mouthpiece 102 may be adjacent to front cover 104, frame 106, and back cover 108. Additionally, in a non-limiting embodiment, mouthpiece 102 may be coupled to the housing devices using a bayonet connection.

In fig. 4 is a view of the proximal end of the nicotine-containing e-cigarette smoking device of FIG. 1. As shown in FIG. 4, the outlet surface of the mouthpiece 102 defines a plurality of steam outlets. In a non-limiting embodiment, the outlet surface of the mouthpiece 102 may be elliptical in shape. In addition, the outlet surface of the mouthpiece 102 may include a first web corresponding to a major axis of the elliptical shaped outlet surface and a second web corresponding to a minor axis of the elliptical shaped outlet surface. In addition, the first web and the second web may intersect perpendicularly and be formed integrally by portions of the mouthpiece 102. Although the outlet surface is shown as defining four steam outlets, it should be understood that the exemplary embodiments are not limited to this. For example, the outlet surface may define fewer than four (eg, one, two) steam outlets or more than four (eg, six, eight) steam outlets.

In fig. 5 is a view of the distal end of the nicotine-containing e-cigarette smoking device of FIG. 1. As shown in FIG. 5, a distal end of the nicotine-containing e-cigarette smoking device 500 includes a port 110. The port 110 is configured to receive electrical current (e.g., via a USB/mini-USB cable) from an external power source to charge an internal power supply within the e-cigarette device 500. smoking an e-cigarette containing nicotine. In addition, port 110 may also be configured to send data (eg, via a USB/mini-USB cable) to another nicotine e-cigarette smoking device or other electronic device (eg, phone, tablet, computer) and/or or receiving data from them. In addition, the nicotine-containing e-cigarette smoking device 500 may be configured to communicate wirelessly with another electronic device, such as a telephone, using an application program installed on the electronic device. In such a case, the adult vaper can control or otherwise interact with the nicotine e-cigarette vaping device 500 (e.g., locate the exact location of the nicotine e-cigarette vaping device, check usage information, change operating parameters) through the application.

In fig. 6 is a perspective view of the nicotine-containing e-cigarette smoking device of FIG. 1. In FIG. 7 is an enlarged view of the inlet opening of the accommodating member shown in FIG. 6. As shown in FIG. 6-7 and as briefly discussed above, the nicotine-containing e-cigarette smoking device 500 includes a nicotine housing assembly 300 configured to hold a nicotine-containing vapor formulation. The nicotine housing assembly 300 has an upstream end (which faces the light guide assembly) and a downstream end (which faces the mouthpiece 102). In a non-limiting embodiment, the upstream end is the opposite surface of the nicotine housing assembly 300 relative to the downstream end. The upstream end of the nicotine housing assembly 300 defines the housing inlet 322. The device body 100 defines a through hole (eg, through hole 150 shown in FIG. 9) configured to receive a nicotine housing assembly 300. In an exemplary embodiment, the inclined structure 112 of the device body 100 defines a through hole and includes an upstream rim. As shown in particular in FIG. 7, the upstream rim of the inclined structure 112 is angled (eg, recessed) such that the accommodating element inlet 322 is visible when the nicotine accommodating element assembly 300 is seated within the through opening of the device body 100.

For example, rather than following the contour of the front cover 104 (to be generally flush with the front surface of the nicotine accommodating member assembly 300 and therefore concealing the accommodating member inlet 322), the upstream rim of the ramp structure 112 is shaped like a bucket. , configured to direct ambient air into the inlet 322 of the accommodating element. This angular/bucket configuration (which, for example, may be curved) can help reduce or prevent blockage of the air inlet (eg, accommodating member inlet 322) of the e-cigarette nicotine smoking device 500. The depth of the scoop may be such that less than half (eg, less than a quarter) of the upstream end surface of the nicotine accommodating member assembly 300 is visible. Additionally, in a non-limiting embodiment, the accommodating member inlet 322 is shaped like a groove. In addition, if the device body 100 is considered to extend in a first direction, then the groove may be considered to extend in a second direction, the second direction being perpendicular to the first direction.

In fig. 8 is a cross-sectional view of the nicotine-containing e-cigarette smoking device of FIG. 6. In FIG. 8, a section is made along the longitudinal axis of the device 500 for smoking an e-cigarette containing nicotine. As shown, the device body 100 and nicotine housing assembly 300 include mechanical components, electronic components, and/or circuitry associated with operation of the nicotine-containing e-cigarette smoking device 500, which are discussed in more detail herein and/or included incorporated into this document by reference. For example, the nicotine housing assembly 300 may include mechanical components operable to release a nicotine-containing vapor formulation from a sealed reservoir located within. The nicotine housing assembly 300 may also have mechanical components configured to engage the device body 100 to facilitate insertion and seating of the nicotine housing assembly 300.

In addition, the nicotine container assembly 300 may be a “smart container” that contains electronic components and/or circuitry configured to store, receive, and/or transmit information to or from the device body 100. Such information may be used to authenticate the nicotine container assembly 300 for use with the device body 100 (eg, to prevent the use of an unapproved/counterfeit nicotine container assembly). In addition, the information may be used to identify the type of nicotine container assembly 300, which is then correlated with the smoking profile of the e-cigarette based on the identified type. An e-cigarette smoking profile may be designed to set general parameters for heating the nicotine-containing vapor formulation and may be tuned, enhanced, or otherwise adjusted by the adult vaper before and/or while smoking the e-cigarette.

The nicotine housing assembly 300 may also communicate other information to the device main body 100 that may relate to the operation of the device 500 for smoking a nicotine-containing e-cigarette. Examples of relevant information may include the level of nicotine-containing vapor formulation inside the nicotine housing assembly 300 and/or the amount of time that has elapsed since the nicotine housing assembly 300 was inserted into the device body 100 and activated. For example, if the nicotine accommodating member assembly 300 was inserted into the device body 100 and activated much earlier than a certain period of time (for example, more than 6 months ago), the nicotine-containing e-cigarette smoking device 500 may not provide smoking of the e-cigarette, and an adult vaper may be asked to switch to a new nicotine container assembly even if the nicotine container assembly 300 still contains sufficient levels of nicotine-containing preformulated vapor formulation.

The device body 100 may include mechanical components (eg, additional structures) configured to engage, retain, and/or activate the nicotine housing assembly 300. In addition, the device body 100 may include electronic components and/or circuitry configured to receive electrical current to charge an internal power source (e.g., a battery), which in turn is configured to supply power to the housing assembly 300 for nicotine while smoking an electronic cigarette. In addition, the device body 100 may include electronic components and/or circuitry configured to communicate with the nicotine container assembly 300, another nicotine e-cigarette smoking device, other electronic devices (e.g., a telephone, tablet, computer). ) and/or an adult vaper. The information transmitted may include certain data regarding the accommodating member, current detailed e-cigarette smoking information, and/or previous e-cigarette smoking patterns/history. The adult vaper may be notified of such data transmissions through feedback that is tactile (eg, vibrations), audible (eg, beeps), and/or visual (eg, colored/flashing lights). Charging and/or information transfer can be carried out using port 110 (for example, via a USB/mini-USB cable).

In fig. 9 is a perspective view of the main part of the device representing the nicotine-containing e-cigarette smoking device of FIG. 6. As shown in FIG. 9, the inclined structure 112 of the device main body 100 defines a through hole 150. The through hole 150 is configured to receive a nicotine accommodating member assembly 300. To facilitate insertion and seating of the nicotine housing assembly 300 within the through hole 150, the upstream rim of the inclined structure 112 includes a first upstream lip 128a and a second upstream lip 128b. The through hole 150 may be rectangular in shape with rounded corners. In an exemplary embodiment, the first upstream protrusion 128a and the second upstream protrusion 128b are integrally formed with the inclined structure 112 and are located on two rounded corners of the upstream rim.

The downstream side wall of the ramp 112 may define a first downstream opening, a second downstream opening, and a third downstream opening. A retaining structure comprising a first downstream projection 130a and a second downstream projection 130b engages the inclined structure 112 such that the first downstream projection 130a and the second downstream projection 130b extend through the first downstream opening and the second downstream opening, respectively, of the inclined structure 112 and into the through hole 150. In addition, the distal end of the mouthpiece 102 extends through the third downstream opening of the inclined structure 112 and into the through hole 150 so as to be between the first downstream projection 130a and the second downstream projection 130b.

In fig. 10 is a front view of the main part of the device of FIG. 9. As shown in FIG. 10, the device body 100 includes an electrical device connector 132 located on the upstream side of the through-hole 150. The electrical device connector 132 of the device body 100 is configured to be electrically connected to a nicotine accommodating member assembly 300 that is seated within the through-hole. openings 150. As a result, power can be supplied from the device main body 100 to the nicotine housing assembly 300 via the device electrical connector 132 while smoking the e-cigarette. Additionally, data may be sent to and/or received from the device main body 100 and the nicotine housing assembly 300 via the device electrical connector 132.

In fig. 11 is an enlarged perspective view of the through hole of FIG. 10. As shown in FIG. 11, the first upstream protrusion 128a, the second upstream protrusion 128b, the first downstream protrusion 130a, the second downstream protrusion 130b, and the distal end of the mouthpiece 102 protrude into the through hole 150. In an example In an embodiment, the first upstream protrusion 128a and the second upstream protrusion 128b are stationary structures (eg, stationary hinges), while the first downstream protrusion 130a and the second downstream protrusion 130b are easily movable structures (for example, retractable elements). For example, the first downstream protrusion 130a and the second downstream protrusion 130b may be configured (eg, spring-loaded) to default to an extended state and also be configured to temporarily transition to a retracted state (and back to extended state) to facilitate insertion of the nicotine housing assembly 300.

Specifically, when the nicotine accommodating member assembly 300 is inserted into the through hole 150 of the device body 100, the recesses on the upstream end surface of the nicotine accommodating member assembly 300 may initially engage the first upstream protrusion 128a and a second upstream protrusion 128b, followed by rotating the nicotine housing assembly 300 (around the first upstream protrusion 128a and the second upstream protrusion 128b) until the recesses on the downstream protrusion downstream, the end surfaces of the nicotine housing assembly 300 will not engage the first downstream projection 130a and the second downstream projection 130b. In such a case, the axis of rotation (during rotation) of the nicotine housing assembly 300 may be orthogonal to the longitudinal axis of the device body 100. In addition, the first downstream protrusion 130a and the second downstream protrusion 130b, which can be offset to allow easy movement, can be retracted when the nicotine housing assembly 300 is rotated into the through hole 150, and elastically extended for engaging with recesses on the downstream end surface of the nicotine housing assembly 300. In addition, engagement of the first downstream protrusion 130a and the second downstream protrusion 130b with the recesses on the downstream end surface of the nicotine housing assembly 300 may cause tactile and/or audible feedback (e.g., an audible click) to notify the adult vaper that the nicotine housing assembly 300 is properly seated in the through hole 150 of the device body 100.

In fig. 12 is an enlarged perspective view of the electrical contacts of the device shown in FIG. 10. The electrical contacts of the device main body 100 are configured to engage with the electrical contacts of the nicotine accommodating member assembly 300 when the nicotine accommodating member assembly 300 is seated within the through hole 150 of the device main body 100. As shown in FIG. 12, the device electrical contacts of the device main 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 housing assembly 300. As illustrated, the power contacts of the device electrical connector 132 include a first power contact and a second power contact (which are positioned to be closer to the front cover 104 than to the rear cover 108). The first power contact (eg, the power contact adjacent to the first upstream protrusion 128a) may be a single integral structure that is distinct from the second power contact and which when assembled includes a protruding portion that extends into the through hole 150. Similarly, the second power contact (eg, the power contact adjacent to the second upstream protrusion 128b) may be a single integral structure that is distinct from the first power contact and which when assembled includes a protruding portion that extends into the through hole 150. The first the power contact and second power contact of the device electrical connector 132 may be movably mounted and offset to engage in the default through-hole 150 and retract (e.g., independently) from the through-hole 150 when subjected to a force that exceeds the offset.

The data contacts of the device electrical connector 132 are configured to transmit data between the nicotine housing assembly 300 and the device body 100. As illustrated, the data pins of the device electrical connector 132 include a row of five protruding portions (which are positioned to be closer to the rear cover 108 than to the front cover 104). The data contacts of the electrical device connector 132 may be separate structures that, when assembled, extend into the through hole 150. The data contacts of the electrical device connector 132 may also be movably mounted and offset (eg, via a serpentine structure and/or springs) such that to enter the through hole 150 by default and retract (eg, independently) from the through hole 150 when subjected to a force that exceeds the displacement. For example, when the nicotine accommodating member assembly 300 is inserted into the through hole 150 of the device body 100, the electrical contacts of the accommodating member of the nicotine accommodating member assembly 300 will be pressed against the corresponding electrical contacts of the device main body 100. As a result, the power contacts and data contacts of the device electrical connector 132 will be retracted (e.g., at least partially retracted) into the device body 100, but will continue to press against the corresponding electrical contacts of the accommodating element due to their resilient arrangement, thereby helping to ensure proper electrical connection between a device body 100 and a nicotine housing assembly 300. In addition, such a connection may also be mechanically reliable and have minimal contact resistance to allow power and/or signals to be transferred and/or exchanged between the device body 100 and the nicotine housing assembly 300 in a reliable and accurate manner. Although various aspects have been discussed with respect to the electrical contacts of the apparatus of the apparatus body 100, it should be understood that the exemplary embodiments are not limited thereto and that other configurations may be used.

In fig. 13 is a partial exploded view including the mouthpiece shown in FIG. 12. As shown in FIG. 13, the mouthpiece 102 is configured to engage with the device housing through a holding structure 140. In an exemplary embodiment, the holding structure 140 is positioned to be primarily located between the frame 106 and the inclined structure 112. As shown, the holding structure 140 is positioned within the device housing such that that the proximal end of the support structure 140 extends through the proximal end of the frame 106. The support structure 140 may extend slightly beyond or be substantially flush with the proximal end of the frame 106. The proximal end of the holding structure 140 is configured to receive the distal end of the mouthpiece 102. The proximal end of the holding structure 140 may be a female end, while the distal end of the mouthpiece may be a male end.

For example, the mouthpiece 102 may be connected (eg, removably connected) to the retention structure 140 using a bayonet connection. In such a case, the female end of the holding structure 140 may define a pair of opposing L-shaped slots, while the male end of the mouthpiece 102 may have opposing radial elements 134 (e.g., radial pins) configured to engage the L-shaped slots of the holding structure 140 Each of the L-shaped grooves of the holding structure 140 may have a longitudinal portion and a circumferential portion. Optionally, the edge of the circumferential portion may have a serrated portion to help reduce or prevent the possibility that the radial member 134 of the mouthpiece 102 will inadvertently disengage. In a non-limiting embodiment, the longitudinal portions of the L-shaped slots extend parallel to and along the longitudinal axis of the device body 100, while the circumferential portions of the L-shaped slots extend about the longitudinal axis (eg, the central axis) of the device body 100. As a result, to connect the mouthpiece 102 to the device casing, the mouthpiece 102 shown in FIG. 13 is initially rotated 90 degrees to align the radial members 134 with the entrances to the longitudinal portions of the L-shaped slots of the retaining structure 140. The mouthpiece 102 is then pushed into the retaining structure 140 such that the radial members 134 slide along the longitudinal portions of the L-shaped slots until until a connection is achieved with each of the circumferential parts. At this point, the mouthpiece 102 is then rotated such that the radial members 134 move over the circumferential portions until the edge of each is reached. In the case where a notched portion is present on each edge, tactile and/or audible feedback (eg, an audible click) may be provided to notify the adult vaper that the mouthpiece 102 has been properly attached to the device housing.

The mouthpiece 102 defines a vapor passage 136 through which nicotine vapor flows during smoking of the e-cigarette. The vapor passage 136 is in fluid communication with the through hole 150 (namely, where the nicotine housing assembly 300 is seated within the device body 100). The proximal end of the steam passage 136 may include a portion that flares toward the bottom. In addition, the mouthpiece 102 may include an end cap 138. The end cap 138 may taper from its distal end to its proximal end. The outlet surface of the end cap 138 defines a plurality of steam outlets. Although end cap 138 shows four steam outlets, it should be understood that the exemplary embodiments are not limited to this.

In fig. 14 is a partial exploded view including the inclined structure shown in FIG. 9. In FIG. 15 is an enlarged perspective view of the mouthpiece, springs, holding structure and inclined structure shown in FIG. 14. As shown in FIG. 14-15, the inclined structure 112 includes an upstream side wall and a downstream side wall. An upstream side wall of the ramp 112 defines an opening 146 for the connector. The connector opening 146 is configured such that the electrical connector 132 of the device of the device main body 100 is visible or accommodated therein. The downstream side wall of the inclined 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 inclined structure 112 are configured to accommodate the first downstream projection 130a and the second downstream projection 130b, respectively, of the retaining structure 140. The third downstream projection Along the flow path, the opening 148c of the inclined structure 112 is configured to accommodate the distal end of the mouthpiece 102.

As shown in FIG. 14, the first downstream protrusion 130a and the second downstream protrusion 130b are located on the concave side of the holding structure 140. As shown in FIG. 15, the first rod 142a and the second rod 142b are located on the opposite convex side of the holding structure 140. The first spring 144a and the second spring 144b are placed on the first rod 142a and the second rod 142b, respectively. The first spring 144a and the second spring 144b are configured to displace the holding structure 140 relative to the inclined structure 112.

When assembled, the ramp structure 112 may be attached to the frame 106 by a pair of rods on the underside of the upstream rim of the ramp structure 112 and adjacent the connector opening 146. In addition, the retaining structure 140 will be adjacent to the inclined 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 one. opening 148b respectively. The mouthpiece 102 will be connected to the retaining structure 140 such that the distal end of the mouthpiece 102 will extend through the retaining structure 140 as well as the third downstream opening 148c of the inclined structure 112. The first spring 144a and the second spring 144b will be located between the frame 106 and holding structure 140.

When the nicotine housing assembly 300 is inserted into the through hole 150 of the device body 100, the downstream end of the nicotine housing assembly 300 will push the first downstream protrusion 130a and the second downstream protrusion 130b of the retaining structure 140. As a result, the first downstream protrusion 130a and the second downstream protrusion 130b of the retaining structure 140 will spring back and be retracted from the through hole 150 of the device body 100 (due to the compression of the first spring 144a and the second spring 144b ), thereby allowing continued insertion of the nicotine housing assembly 300. In an exemplary embodiment, when the first downstream protrusion 130a and the second downstream protrusion 130b are fully retracted from the through hole 150 of the device body 100, displacement of the retaining structure 140 may cause the ends of the first rod 142a and the second rod 142b to contact. with the inner end surface of the frame 106. Moreover, since the mouthpiece 102 is connected to the holding structure 140, the distal end of the mouthpiece 102 will be retracted from the through hole 150, thereby also causing the proximal end of the mouthpiece 102 (for example, the visible portion including the end cap 138) to move ) at an appropriate distance from the device casing.

Once the nicotine housing assembly 300 is properly inserted such that the first downstream recess and the second downstream recess of the nicotine housing assembly 300 reach a position allowing engagement with the first downstream recess. protrusion 130a and the second downstream protrusion 130b, respectively, the accumulated compressive energy of the first spring 144a and the second spring 144b causes the first downstream protrusion 130a and the second downstream protrusion 130b to elastically extend and engage engaging the first downstream recess and the second downstream recess, respectively, of the nicotine housing assembly 300. Moreover, the engagement may provide tactile and/or audible feedback (eg, an audible click) to notify the adult vaper that the nicotine container assembly 300 is properly seated within the through hole 150 of the device body 100.

In fig. 16 is a partial exploded view including the front cover, frame and rear cover shown in FIG. 14. As shown in FIG. 16, various mechanical components, electronic components, and/or circuitry associated with operation of the nicotine-containing e-cigarette smoking device 500 may be attached to the frame 106. The front cover 104 and the rear cover 108 may be configured to engage the frame 106 by snap-on arrangements. In an exemplary embodiment, the front cover 104 and the rear cover 108 include clips configured to interconnect with corresponding mating elements of the frame 106. The clips may be in the form of tabs with holes configured to receive corresponding mating elements (eg, beveled projections) of the frame 106. In FIG. 16, the front cover 104 has two rows of four clips each (for a total of eight clips for the front cover 104). Likewise, the back cover 108 has two rows of four clips each (for a total of eight clips for the back cover 108). The corresponding mating members of the frame 106 may be located on the inner side walls of the frame 106. As a result, the engaged clips and mating members may be hidden from view when the front cover 104 and the rear cover 108 are snapped together. Alternatively, the front cover 104 and/or the rear cover 108 may be configured capable of engaging with the frame 106 through an interference fit. However, it should be understood that the front cover 104, frame 106, and back cover 108 can be connected using other suitable arrangements and techniques.

In fig. 17 is a perspective view of the nicotine containing assembly of the nicotine-containing e-cigarette smoking device shown in FIG. 6. In FIG. 18 is another perspective view of the nicotine housing assembly of FIG. 17. In FIG. 19 is another perspective view of the nicotine housing assembly of FIG. 18. As shown in FIG. 17-19, the nicotine housing assembly 300 of the nicotine-containing e-cigarette smoking device 500 includes a housing body body configured to hold a nicotine-containing vapor formulation. The main body of the accommodating element has an upstream end and a downstream end. The upstream end of the main body of the accommodating element defines the inlet opening 322 of the accommodating element. The downstream end of the main body of the accommodating element defines a accommodating element outlet 304, which is in fluid communication with the accommodating element inlet 322 at the upstream end. During smoking of the electronic cigarette, air enters the nicotine accommodating member assembly 300 through the accommodating member inlet 322, and nicotine vapor exits the nicotine accommodating member assembly 300 through the accommodating member outlet 304. The accommodating element inlet 322 is shown in the drawings in the form of a groove. However, it should be understood that the exemplary embodiments are not limited to this and that other forms are possible.

The nicotine housing assembly 300 includes a connection module 320 (eg, FIG. 21) that is located within the main body of the housing and is visible through openings at the upstream end. The outer surface of the connection module 320 contains at least one electrical contact. The at least one electrical contact may comprise multiple power contacts. For example, the multiple power contacts may include a first power contact 324a and a second power contact 324b. The first power contact 324a of the nicotine housing assembly 300 is configured to be electrically coupled to a first power contact (eg, a power contact adjacent to the first upstream protrusion 128a in FIG. 12) of the device electrical connector 132 of the device body 100. Likewise, a second power contact 324b of the nicotine accommodating member assembly 300 is configured to be electrically coupled to a second power contact (e.g., a power contact adjacent to the second upstream protrusion 128b in FIG. 12) of the electrical device connector 132 of the device body 100 . In addition, at least one electrical contact of the nicotine housing assembly 300 includes multiple data contacts 326. A plurality of data contacts 326 of the nicotine housing assembly 300 are electrically coupled to the data contacts of the device electrical connector 132 (eg, the row of five protrusions in FIG. 12). Although two power contacts and five data contacts are shown in combination with the nicotine housing assembly 300, it should be understood that other options are possible depending on the design of the device body 100.

In an exemplary embodiment, the nicotine housing assembly 300 includes a front surface, a rear surface opposite the front surface, a first side surface between the front surface and a rear surface, a second side surface opposite the first side surface, an upstream end surface, and a further along the flow, an end surface opposite to the end surface located earlier in the flow. Side and end surface angles (e.g., angle of first side surface and upstream end surface, angle of upstream end surface and second side surface, angle of second side surface and downstream end surface, angle of downstream end surface along the flow of the end surface and the first side surface) can be rounded. However, in some cases the corners may be sharp. In addition, the peripheral edge of the front surface may be in the form of a shoulder. The outer surface of the connection module 320 (which is visible through the main body of the housing) can be considered part of the upstream end surface of the nicotine housing assembly 300. The front surface of the nicotine housing assembly 300 may be wider and longer than the rear surface. In such a case, the first side surface and the second side surface may be inclined inwardly towards each other. The upstream end surface and the downstream end surface can also be inclined inwardly towards each other. Due to the angled surfaces, insertion of the nicotine housing assembly 300 will be in one direction (eg, from the front side (the side associated with the front cover 104) of the device body 100). As a result, the possibility of improper insertion of the nicotine housing assembly 300 into the device body 100 can be reduced or prevented.

As illustrated, the main housing portion of the nicotine housing assembly 300 includes a first housing section 302 and a second housing section 308. The first housing section 302 has a downstream end defining a housing outlet 304. The rim of the accommodating member outlet 304 may optionally be a recessed or depressed area. In such a case, this area may resemble a vault, wherein the side of the rim adjacent to the rear surface of the nicotine accommodating member assembly 300 may be open, while the side of the rim adjacent to the front surface may be surrounded by a raised portion of a further downstream the flow path of the end of the first casing section 302. The raised portion may function as a stop for the distal end of the mouthpiece 102. As a result, this configuration of the accommodating member outlet 304 may facilitate positioning and alignment of the distal end of the mouthpiece 102 (e.g., FIG. 11) through the open side of the rim and its subsequent seating on the raised portion of the distal portion. along the flow path of the end of the first casing section 302. In a non-limiting embodiment, the distal end of the mouthpiece 102 may also comprise (or be formed from) an elastic material that helps create a seal around the housing outlet 304 when the nicotine housing assembly 300 is properly inserted within the through hole 150 of the body 100 devices.

The downstream end of the first housing section 302 further defines at least one downstream recess. In an exemplary embodiment, the at least one downstream recess is in the form of a first downstream recess 306a and a second downstream recess 306b. The accommodating member 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 the first downstream protrusion 130a and the second downstream protrusion 130b, respectively, of the device body 100. As shown in FIG. 11, the first downstream projection 130a and the second downstream projection 130b of the device body 100 may be positioned at adjacent corners of the downstream side wall of the through hole 150. Each of the first downstream recess 306a and the second downstream recess 306b may be in the form of a V-shaped recess. In such a case, each of the first downstream protrusion 130a and the second downstream protrusion 130b of the main body 100 of the device may be in the form of a wedge-shaped structure configured to engage with a corresponding V-shaped recess of the first downstream recess 306a and a second downstream recess 306b. The first downstream recess 306a may be adjacent to the corner of the downstream end surface and the first side surface, while the second downstream recess 306b may be adjacent to the corner of the downstream end surface and the second side surface. surfaces. As a result, the edges of the first downstream recess 306a and the second downstream recess 306b adjacent the first side surface and the second side surface, respectively, can be opened. In such a case, as shown in FIG. 18, each of the first downstream recess 306a and the second downstream recess 306b may be a 3-sided recess.

The second housing section 308 has an upstream end also defining (in addition to the housing inlet 322) a plurality of openings (e.g., a first power contact opening 325a, a second power contact opening 325b, a data contact opening 327), configured such that the connection module 320 (FIGS. 20-21) within the nicotine housing assembly 300 is visible. The upstream end of the second housing section 308 also defines at least one upstream recess. In an exemplary embodiment, the at least one upstream recess is in the form of a first upstream recess 312a and a second upstream recess 312b. The accommodating member 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 the first upstream protrusion 128a and the second upstream protrusion 128b, respectively, of the device body 100. As shown in FIG. 12, the first upstream protrusion 128a and the second upstream protrusion 128b of the device body 100 may be positioned at adjacent corners of the upstream side wall of the through hole 150. The depth of each of the first upstream recess 312a and the second upstream recess 312b may be greater than the depth of each of the first downstream recess 306a and the second downstream recess 306b. The edge of each of the first upstream recess 312a and the second upstream recess 312b may also be more rounded than the edge of each 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 also be U-shaped. In such a case, each of the first upstream protrusion 128a and the second upstream protrusion 128b of the main body 100 of the device may be in the form of a rounded bulge configured to engage a corresponding U-shaped cut of the first upstream recess 312a and a second upstream recess 312b. The first upstream recess 312a may be adjacent to the corner of the upstream end surface and the first side surface, while the second upstream recess 312b may be adjacent to the corner of the upstream end surface and the second side surface. surfaces. As a result, the edges of the first upstream recess 312a and the second upstream recess 312b adjacent the first side surface and the second side surface, respectively, can be opened.

The first housing section 302 may internally define a reservoir configured to hold a nicotine-containing vapor formulation. The reservoir may be configured to seal the nicotine-containing vapor formulation prior to activating the nicotine accommodating member assembly 300 to release the nicotine-containing vapor formulation from the reservoir. By hermetically sealing, the nicotine-containing vapor formulation can be isolated from the environment, as well as internal elements of the nicotine housing assembly 300, which may potentially react with the nicotine-containing vapor formulation, thereby reducing or preventing the possibility of negative effects on the shelf life and/or organoleptic characteristics (e.g. taste) of the nicotine-containing vapor formulation. The second housing section 308 may include structures configured to activate the nicotine housing assembly 300 and to accommodate and heat a nicotine-containing vapor formulation released from the reservoir upon activation.

The nicotine housing assembly 300 may be manually activated by an adult vaper prior to inserting the nicotine housing assembly 300 into the device body 100. Alternatively, the nicotine housing assembly 300 may be activated as part of the insertion of the nicotine housing assembly 300 into the device body 100. In an exemplary embodiment, the second housing body section 308 includes a perforator configured to release a nicotine-containing vapor formulation from the reservoir into the first housing section 302 upon activation of the nicotine housing assembly 300. The punch may take the form of a first activation punch 314a and a second activation punch 314b, which will be discussed in more detail herein.

To manually activate the nicotine container assembly 300, an adult vaper may press inward the first activation punch 314a and the second activation punch 314b (e.g., simultaneously or sequentially) before inserting the nicotine container assembly 300 into the through hole 150 of the body 100. devices. For example, the first activation punch 314a and the second activation punch 314b may be manually pressed until their ends are substantially aligned with the upstream end surface of the nicotine housing assembly 300. In an exemplary embodiment, the inward movement of the first activation punch 314a and the second activation punch 314b causes a puncture or other breach of the seal of the reservoir to release the nicotine-containing vapor formulation therefrom.

Alternatively, to activate the nicotine housing assembly 300 as part of the insertion of the nicotine housing assembly 300 into the device body 100, the nicotine housing assembly 300 is initially positioned such that the first upstream recess 312a and the second upstream recess 312a the downstream recess 312b engages the first upstream protrusion 128a and the second upstream protrusion 128b, respectively (eg, an upstream engagement). Because each of the first upstream protrusion 128a and the second upstream protrusion 128b of the main body 100 of the device may be in the form of a rounded bulge configured to engage a corresponding U-shaped cut of the first upstream recess 312a and the second of the upstream recess 312b, the nicotine housing assembly 300 can subsequently be relatively easily rotated around the first upstream protrusion 128a and the second upstream protrusion 128b and into the through hole 150 of the device body 100.

With respect to the rotation of the nicotine housing assembly 300, the axis of rotation can be viewed as extending through the first upstream protrusion 128a and the second upstream protrusion 128b and oriented orthogonally to the longitudinal axis of the device body 100. During initial position setting and subsequent rotation of the nicotine accommodating member assembly 300, the first activation punch 314a and the second activation punch 314b will contact the upstream side wall of the through hole 150 and transition from an extended state to a retracted state as the as the first activation punch 314a and the second activation punch 314b are pushed (for example, simultaneously) into the second housing section 308 as the nicotine accommodating member assembly 300 advances into the through hole 150. When the downstream end of the accommodating member is in Nicotine assembly 300 reaches a region of the downstream side wall of the through hole 150 and comes into contact with the first downstream projection 130a and the second downstream projection 130b, the first downstream projection 130a and the second downstream projection 130a. The downstream protrusion 130b will retract and then elastically extend (eg, spring back) when the position of the nicotine housing assembly 300 allows the first downstream protrusion 130a and the second downstream protrusion 130b of the device body 100 engage the first downstream recess 306a and the second downstream recess 306b, respectively, of the nicotine housing assembly 300 (eg, a downstream engagement).

As noted above, in accordance with an exemplary embodiment, the mouthpiece 102 is attached to a holding structure 140 (of which the first downstream projection 130a and the second downstream projection 130b are part). In such a case, retraction of the first downstream protrusion 130a and the second downstream protrusion 130b from the through hole 150 will simultaneously cause the mouthpiece 102 to move a corresponding distance in the same direction (eg, the downstream direction). On the other hand, the mouthpiece 102 will spring back simultaneously with the first downstream protrusion 130a and the second downstream protrusion 130b when the nicotine housing assembly 300 is sufficiently inserted to facilitate the downstream engagement. In addition to the elastic engagement of the first downstream protrusion 130a and the second downstream protrusion 130b, the distal end of the mouthpiece 102 is also adapted to be offset relative to the nicotine housing assembly 300 (and is aligned with the outlet 304 of the nicotine accommodating element to form a relatively vapor-tight seal) when the nicotine housing assembly 300 is properly seated within the through hole 150 of the device body 100.

Additionally, the downstream engagement may provide an audible click and/or tactile feedback to indicate that the nicotine housing assembly 300 is properly seated within the through hole 150 of the device body 100. When properly seated, the nicotine housing assembly 300 will be mechanically, electrically, and fluidly coupled to the device body 100. While non-limiting embodiments herein describe an upstream engagement of the nicotine housing assembly 300 occurring before a downstream engagement, it should be understood that suitable mating, activation and/or electrical arrangements may be reversed, so that the downstream engagement takes place before the upstream engagement.

In fig. 20 is a partial exploded view of the nicotine housing assembly of FIG. 19. As shown in FIG. 20, the first casing section 302 includes a steam passage 316. The vapor passage 316 is configured to accommodate nicotine vapor generated during smoking of the electronic cigarette and is in fluid communication with the accommodating member outlet 304. In an exemplary embodiment, the steam passage 316 may gradually increase in size (eg, diameter) as it extends toward the accommodating member outlet 304. In addition, the steam passage 316 may be formed integrally with the first casing section 302. An insert 342 and a seal 344 are located at the upstream end of the first housing section 302 to define a reservoir of the nicotine accommodating element assembly 300. For example, the insert 342 may be seated within the first casing section 302 such that the peripheral surface of the insert 342 engages the inner surface of the first casing section 302 along the rim (e.g., through an interference fit), such that the interface of the peripheral surface of the insert 342 and the inner the surface of the first housing section 302 is fluid impermeable (eg, liquid impermeable and/or air impermeable). In addition, a seal 344 is attached to the upstream side of the insert 342 to seal the reservoir outlets in the insert 342 to provide a fluid-tight (e.g., liquid-tight and/or air-tight) containment of the nicotine-containing vapor formulation. in the tank. Insert 342 and seal 344 are also illustrated, for example, in FIG. 24 and will be discussed in more detail herein.

The upstream end of the second housing section 308 defines a housing 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 along the flow path, a recess 312b, an opening 315a for the first punch, and an opening 315b for the second punch. As noted above, the accommodating member inlet 322 allows air to flow into the nicotine accommodating member assembly 300 during smoking of the electronic cigarette, while the first power contact opening 325a, the second power contact opening 325b, and the data contact opening 327 are configured so that the first power contact 324a, the second power contact 324b, and the data contacts 326, respectively, of the connection module 320 are visible. In an exemplary embodiment, the first power contact 324a and the second power contact 324b are mounted on the module housing 354 of the connection module 320. In addition, the contacts 326 data may be placed on a printed circuit board (PCB) 362. In addition, the accommodating member inlet 322 may be located between the first upstream recess 312a and the second upstream recess 312b, while the contact openings ( for example, a first power contact opening 325a, a second power contact opening 325b, a data contact opening 327) may be located between the first punch opening 315a and the second punch opening 315b. The first punch opening 315a and the second punch opening 315b are configured to accommodate the first activation punch 314a and the second activation punch 314b, respectively, extending therethrough.

In fig. 21 is a perspective view of the connection module shown in FIG. 20. In FIG. 22 is another perspective view of the connection module of FIG. 21. As shown in FIG. 21-22, the overall frame of the connection module 320 contains a module housing 354. In addition, the connection module 320 has multiple surfaces, including an outer surface and side surfaces adjacent to the outer surface. In an exemplary embodiment, the outer surface of the connection module 320 consists of the upstream surfaces of the module housing 354, the first power contact 324a, the second power contact 324b, the data contacts 326, and the printed circuit board (PCB) 362. The side surfaces of the connection module 320 may be integral. parts of the module housing 354 and generally orthogonal to the outer surface.

The nicotine container assembly 300 internally defines a flow path from the container inlet 322 to the container outlet 304. The flow path through the nicotine housing assembly 300 includes, among other things, a first divergent portion, a second divergent portion, and a convergent portion. The accommodating member inlet 322 is located upstream of the first divergent portion and the second divergent portion of the flow path. In particular, as shown in FIG. 21, a side surface (eg, an inlet side surface) of the module housing 354 (and connection module 320) above the first power contact 324a and the second power contact 324b is recessed to define the separator 329 along with the initial segments of the first divergent portion and the second divergent portion of the flow path. In an exemplary embodiment in which the spacer 329 is depressed relative to the outer surface of the module housing 354 (e.g., FIG. 21), the side surface of the module housing 354 above the first power contact 324a and the second power contact 324b may also be considered to define the inlet portion of the flow path. , which is located downstream of the inlet 322 of the containing element and is located upstream of the first divergent portion and the second divergent portion of the flow path.

A pair of longer side surfaces (eg, vertical side surfaces) of the module housing 354 are also recessed so as to define subsequent segments of the first divergent portion and the second divergent portion of the flow path. As used herein, the pair of longer side surfaces of the module housing 354 may alternatively be referred to as lateral surfaces. The sector of the module housing 354 occupied by the printed circuit board (PCB) 362 shown in FIG. 21 (but shown in FIG. 30) defines further segments of the first divergent portion and the second divergent portion along with the convergent portion of the flow path. The additional segments of the first divergent portion and the second divergent portion comprise a first curved segment (eg, first curved path 330a) and a second curved segment (eg, second curved path 330b), respectively. As will be discussed in more detail herein, the first divergent portion and the second divergent portion converge to form a convergent portion of the flow path.

When the connection module 320 is seated within the receiving cavity in the downstream side of the second housing section 308, the non-recessed side surfaces of the module housing 354 are in contact with the side walls of the receiving cavity of the second housing section 308, while the recessed side surfaces of the module housing 354 are in contact with the side walls of the module housing 354. the walls of the receiving cavity define the first divergent part and the second divergent part of the flow path. The fit of the coupling module 320 within the receiving cavity of the second housing section 308 may be accomplished using a tight-fit arrangement such that the coupling module 320 remains substantially stationary within the nicotine housing assembly 300.

As shown in FIG. 22, the connection module 320 includes a wick 338 that is configured to transfer the nicotine-containing vapor formulation to a heater 336. The heater 336 is configured to heat the nicotine-containing vapor formulation during smoking of the electronic cigarette to generate nicotine vapor. The heater 336 is electrically coupled to at least one electrical contact of the connection module 320. For example, one end (e.g., the first end) of the heater 336 may be connected to the first power contact 324a while the other end (e.g., the second end) of the heater 336 may be connected to the second power pin 324b. In an exemplary embodiment, heater 336 includes a folded heating element. In such a case, the wick 338 may have a flat shape adapted to be held by a folded heating element. When the nicotine accommodating member assembly 300 is assembled, the wick 338 is adapted to be in fluid communication with the absorbent material 346 (e.g., FIG. 25) such that the nicotine-containing vapor formulation contained in the absorbent material 346 (when the accommodating member is assembly 300 for nicotine activated) will be transferred to the wick 338 by capillary action.

In an exemplary embodiment, the incoming air flow entering the nicotine housing assembly 300 through the housing inlet 322 is directed by the separator 329 into the first divergent portion and the second divergent portion of the flow path. The separator 329 may be wedge-shaped and configured to separate the incoming air flow into opposing directions (eg, at least initially). The divided air stream may comprise a first air stream (which passes through the first divergent portion of the flow path) and a second air stream (which passes through the second divergent portion of the flow path). After separation by the separator 329, the first air flow passes along the lateral surface of the inlet and is directed further around the corner to and along the first lateral surface to the first curved path 330a. Likewise, the second air flow passes along the side surface of the inlet and is directed further around the corner to and along the second lateral surface to the second curved path 330b (eg, FIG. 30). The converging portion of the flow path is located downstream of the first diverging portion and the second diverging portion. Heater 336 and wick 338 are located downstream of the converging portion of the flow path. Thus, the first air stream combines with the second air stream at a converging portion (eg, converging path 330c in FIG. 30) of the flow path to form a combined flow before passing through the module outlet 368 (eg, designated in FIG. 28) in the housing 354 module to heater 336 and wick 338.

In fig. 23 is an exploded view including the wick and heater shown in FIG. 22. As shown in FIG. 23, the wick 338 may be a fibrous pad or other structure with pores/voids provided for capillary action. Additionally, the wick 338 may be rectangular in shape, although exemplary embodiments are not limited to this. For example, the wick 338 may have the alternative shape of an irregular hexagon, with two of the sides angled inward and toward the heater 336. The wick 338 may be shaped into a desired shape, or it may be cut into such a shape from a larger sheet of material. If the bottom section of the wick 338 tapers toward the winding section of the heater 336 (e.g., in a hexagon shape), the likelihood that the nicotine-containing vapor formulation will be located in the portion of the wick 338 that continually avoids evaporation (due to its distance from the heater 336) , can be reduced or eliminated. In addition, as noted above, the heater 336 may include a folded heating element configured to engage a wick 338. The folded heating element may also include at least one pin 337 configured to protrude into the wick 338.

In an exemplary embodiment, heater 336 is configured to undergo Joule heating (which is also known as ohmic/resistive heating) when electrical current is applied to it. In more detail, heater 336 may be formed from one or more conductors (resistive materials) and configured to generate heat when electric current passes through it. Electrical current may be supplied from a power source (eg, a battery) within the device body 100 and transferred to the heater 336 through the first power contact 324a or the second power contact 324b.

Suitable conductors (resistive materials) for heater 336 include an iron-based alloy (eg, stainless steel) and/or a nickel-based alloy (eg, nichrome). Heater 336 may be made of a conductive sheet (eg, metal, alloy) that is stamped to be cut into a winding pattern. The winding pattern may have curved segments alternately arranged with horizontal segments to allow the horizontal segments to zigzag back and forth while extending parallel. In addition, the width of each of the horizontal winding pattern segments may be substantially equal to the distance between adjacent horizontal winding pattern segments, although exemplary embodiments are not limited to this. To obtain the shape of the heater 336 shown in the drawings, the winding pattern may be folded to capture the wick 338. Additionally, when the pins 337 are part of the heater 336, the protruding portions corresponding to the pins 337 are bent (e.g., inward and/or orthogonally) until the winding pattern is folded. Thanks to the pins 337, the likelihood of the wick 338 slipping out of the heater 336 will be reduced or eliminated. The heater and related structures are discussed in more detail in US Patent Application No. 15/729909, entitled "Folded Heater For Electronic Vaping Device", filed October 11, 2017, the entire contents of which are incorporated herein by reference.

In fig. 24 is an exploded view including the first section of the nicotine housing assembly housing of FIG. 17. As shown in FIG. 24, the first casing section 302 includes a steam passage 316. The vapor passage 316 is configured to accommodate nicotine vapor generated by the heater 336 and is in fluid communication with the accommodating member outlet 304. In an exemplary embodiment, the steam passage 316 may gradually increase in size (eg, diameter) as it extends toward the accommodating member outlet 304. In addition, the steam passage 316 may be formed integrally with the first casing section 302. An insert 342 and a seal 344 are located at the upstream end of the first housing section 302 to define a reservoir of the nicotine accommodating element assembly 300. For example, the insert 342 may be seated within the first casing section 302 such that the peripheral surface of the insert 342 engages the inner surface of the first casing section 302 along the rim (e.g., through an interference fit), such that the interface of the peripheral surface of the insert 342 and the inner the surface of the first housing section 302 is fluid impermeable (eg, liquid impermeable and/or air impermeable). In addition, a seal 344 is attached to the upstream side of the insert 342 to seal the reservoir outlets in the insert 342 to provide a fluid-tight (e.g., liquid-tight and/or air-tight) containment of the nicotine-containing vapor formulation. in the tank. Herein, the first housing section 302, insert 342, and seal 344 may collectively be referred to as the first section. As will be discussed in more detail herein, the first section is configured to hermetically seal the nicotine-containing vapor formulation prior to activation of the nicotine accommodating member assembly 300.

In an exemplary embodiment, insert 342 includes a holder portion that projects from an upstream side (as shown in FIG. 24) and a connector portion that projects from a downstream side (not shown in FIG. .24). The insert holder portion 342 is configured to retain absorbent material 346 (eg, FIG. 25), while the insert connector portion 342 is configured to engage the steam passage 316 of the first housing section 302. The insert connector portion 342 may be configured to fit within the steam passage 316 and thereby engage the interior of the steam passage 316. Alternatively, the connector portion of the insert 342 may be configured to receive the steam passage 316 and therefore engage with the outer portion of the steam passage 316. Insert 342 also defines reservoir outlets through which nicotine-containing vapor formulation flows out when seal 344 is pierced during activation of nicotine accommodating member assembly 300. The holder portion and connector portion of the insert 342 may be located between the reservoir outlets (eg, the first and second reservoir outlets), although the exemplary embodiments are not limited to this. In addition, insert 342 defines a steam line extending through the holder portion and the connector portion. As a result, when the insert 342 is seated within the first housing section 302, the vapor line of the insert 342 will be aligned and in fluid communication with the steam path 316 to form a continuous path through the reservoir to the accommodating element outlet 304 for the nicotine vapor generated by the heater 336. time of smoking an electronic cigarette.

A seal 344 is attached to the upstream side of the insert 342 to close the reservoir outlets in the insert 342. In an exemplary embodiment, the seal 344 defines an opening (e.g., a central opening) configured to provide a suitable clearance to accommodate the holder portion ( protruding from the upstream side of the insert 342) when the seal 344 is attached to the insert 342. When the seal 344 is pierced by the first activation punch 314a and the second activation punch 314b of the nicotine housing assembly 300, the two pierced sections of the seal 344 will be pushed into the reservoir at valves, thereby creating two pierced openings (for example, one on each side of the central opening) in the seal 344. The size and shape of the pierced openings in the seal 344 may match the size and shape of the reservoir outlets in the insert 342. In contrast, in unpunctured condition, as shown in Fig. 24, the seal 344 will have a flat shape and only one opening (eg, a central opening). The seal 344 is designed to be strong enough to remain intact during normal movement and/or handling of the nicotine accommodating member assembly 300 to avoid premature/unintentional breakage. For example, seal 344 may be a coated foil (eg, aluminum-based polyethylene terephthalate (PET)).

In fig. 25 is a partial exploded view including a second section of the nicotine housing assembly housing of FIG. 17. As shown in FIG. 25, the second housing section 308 is configured to contain various components configured to release, accommodate, and heat the nicotine-containing vapor formulation. For example, the first activation punch 314a and the second activation punch 314b are configured to pierce the reservoir in the first housing section 302 to release the nicotine-containing vapor formulation. Each of the first activation punch 314a and the second activation punch 314b has a distal end that extends through a respective one of the first punch opening 315a or the second punch opening 315b in the second housing section 308. In an exemplary embodiment, the distal ends of the first activation punch 314a and the second activation punch 314b are visible after assembly (e.g., FIG. 17), while the remainder of the first activation punch 314a and the second activation punch 314b are hidden from view within the housing assembly 300 for nicotine. In addition, each of the first activation punch 314a and the second activation punch 314b has a proximal end that is positioned to be adjacent to and upstream of the seal 344 before activating the nicotine accommodating member assembly 300. When the first activation punch 314a and the second activation punch 314b are pushed into the second activation housing section 308 of the nicotine housing assembly 300, the proximal end of each of the first activation punch 314a and the second activation punch 314b will be pushed forward through the insert 342 and, as a result, pierce the seal. 344, which will release the nicotine-containing vapor formulation from the reservoir. The movement of the first activation punch 314a may be independent of the movement of the second activation punch 314b (and vice versa). The first activation punch 314a and the second activation punch 314b will be discussed in more detail herein.

Absorbent material 346 may be seated within a holder (eg, top lid holder 345). Absorbent material 346 is also located downstream of and in fluid communication with wick 338. In addition, as noted above, the absorbent material 346 is configured to engage the holder portion of the insert 342 (which, as shown in FIG. 24, protrudes from the upstream side of the insert 342). The absorbent material 346 may be ring-shaped, although exemplary embodiments are not limited to this. As shown in FIG. 25, the absorbent material 346 may resemble a hollow cylinder. In such a case, the outer diameter of the absorbent material 346 may be substantially equal to the length of the wick 338 (or slightly larger). The inner diameter of the absorbent material 346 may be smaller than the average outer diameter of the insert holder portion 342, resulting in an interference fit. To facilitate engagement with the absorbent material 346, the tip of the insert holder portion 342 may be tapered. The absorbent material 346 is configured to accommodate and retain an amount of nicotine-containing vapor formulation released from the reservoir when the nicotine accommodating member assembly 300 is activated.

The wick 338 is located within the nicotine housing assembly 300 such that it is in fluid communication with the absorbent material 346 such that the nicotine-containing vapor formulation can be drawn from the absorbent material 346 onto the heater 336 by capillary action. The wick 338 may physically contact an upstream side of the absorbent material 346 (eg, the bottom of the absorbent material 346, as shown in FIG. 25). Additionally, the wick 338 may correspond to the diameter of the absorbent material 346, although the exemplary embodiments are not limited to this.

As illustrated in FIG. 25 (as well as the previous FIG. 23), the heater 336 may be configured to be folded to engage and make thermal contact with opposing surfaces of the wick 338. The heater 336 is configured to heat the wick 338 during smoking of the e-cigarette to generate nicotine vapor. To facilitate such heating, the first end of the heater 336 may be electrically coupled to the first power terminal 324a, while the second end of the heater 336 may be electrically coupled to the second power terminal 324b. As a result, electric current may be supplied from a power source (eg, a battery) within the device main body 100 and transferred to the heater 336 through the first power contact 324a or the second power contact 324b. Pertinent details of other aspects of connection module 320 that have already been discussed above (eg, in connection with FIGS. 21-22) will not be repeated in this section for the sake of brevity. In an exemplary embodiment, although not shown in FIG. 25, the second housing section 308 includes a receiving cavity for the connection module 320. Collectively, the second housing section 308 and its components discussed above may be referred to as the second section. During smoking of the e-cigarette, nicotine vapor generated by the heater 336 is drawn through the steam line of the insert 342, through the steam passage 316 of the first housing section 302, outward from the accommodating member outlet 304 of the nicotine accommodating member assembly 300, and through the vapor passage 136 of the mouthpiece. 102 to the steam outlets.

In fig. 26 is an exploded view of the top cap holder shown in FIG. 25. As shown in FIG. 26, the upper lid holder 345 includes a base portion 345a and a cylindrical portion 345b. In an exemplary embodiment, the base portion 345a and the cylindrical portion 345b are formed as a single unit. The cylindrical portion 345b defines a pocket configured to receive the absorbent material 346. Optionally, the inner bottom surface of the pocket may have a lip (or other protruding portion) to support the absorbent material 346 so that the absorbent material 346 does not simply slide or hang through the upper lid holder 345 (e.g. when the absorbent material 346 is impregnated with the nicotine-containing vapor formulation released from the reservoir). In addition, the base portion 345a defines a groove configured to receive the spacer 345c. In addition, a pair of integrally formed rods may extend from the base portion 345a and along the outer side of the cylindrical portion 345b to extend beyond the rim of the cylindrical portion 345b. When the top cap holder 345 is assembled within the nicotine housing assembly 300, this pair of integral rods may be adjacent to the underside of the insert 342 by a seal portion 344 located therebetween.

In fig. 27 is an exploded view of the activation punch shown in FIG. 25. As shown in FIG. 27, the activation punch may take the form of a first activation punch 314a and a second activation punch 314b. Although two activation punches are shown herein and discussed in combination with non-limiting embodiments, it should be understood that alternatively, the nicotine housing assembly 300 may contain only one activation punch. In fig. 27, the first activation punch 314a may include a first plate 348a, a first actuator 350a, and a first O-ring 352a. Likewise, the second activation punch 314b may include a second plate 348b, a second actuator 350b, and a second O-ring 352b.

In an exemplary embodiment, the first plate 348a and the second plate 348b are formed integrally with the first actuator 350a and the second actuator 350b, respectively. Alternatively, the first plate 348a and the second plate 348b may be configured to be mounted or attached to the upper portions (eg, proximal portions) of the first actuator 350a and the second actuator 350b, respectively. Installation or attachment may be achieved using a snap joint, an interference fit (eg, a friction fit), an adhesive, or other suitable joining technique. The top of each of the first plate 348a and the second plate 348b may have one or more curved or concave edges that taper upward to a pointed tip. For example, each of the first plate 348a and the second plate 348b may have two pointed tips with a concave edge therebetween and a curved edge adjacent to each pointed tip. The radii of curvature of a concave edge and curved edges may be the same, while their arc lengths may differ. The first plate 348a and the second plate 348b may be formed from sheet metal (eg, stainless steel) that is cut or otherwise shaped to produce the desired profile and bent into its final shape. Alternatively, the first plate 348a and the second plate 348b may be formed from plastic (eg, when formed integrally with the first actuator 350a and the second actuator 350b).

In a plan view, the size and shape of the first plate 348a, the second plate 348b, and the portions of the first actuator 350a and the second actuator 350b with which they are integral (or on which they are mounted) may correspond to the size and shape of the reservoir outlets in the insert 342 In addition, as shown in FIG. 27, the first activation punch 314a and the second activation punch 314b may include protruding edges (e.g., curved inner flanges facing each other) configured to push two pierced sections of the seal 344 into the reservoir as the first plate 348a and the second plate 348b move into the tank. In a non-limiting embodiment, when the first activation punch 314a and the second activation punch 314b are fully inserted into the nicotine housing assembly 300, two valves (from the two pierced seal sections 344) may be positioned between the curved sidewalls of the insert 342 reservoir outlets and the corresponding bends. the protruding edges of the first activation punch 314a and the second activation punch 314b. As a result, the likelihood that the two pierced openings in the seal 344 will be blocked (by the two valves of the two pierced sections) can be reduced or prevented. In addition, the first activation punch 314a and the second activation punch 314b may be configured to direct the nicotine-containing vapor formulation from the reservoir to the absorbent material 346 within the top cap holder 345.

A lower portion (eg, a distal portion) of each of the first actuator 350a and the second actuator 350b is configured to extend through a lower section (eg, an upstream end) of the second housing section 308. This rod-shaped portion of each of the first actuator 350a and the second actuator 350b may also be referred to as a shaft. The first o-ring 352a and the second o-ring 352b may be seated in annular grooves in 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 the shafts of the first actuator 350a and the second actuator 350b, as well as the internal surfaces of the corresponding openings in the second casing section 308 to provide a fluid-tight seal. As a result, when the first activation punch 314a and the second activation punch 314b are pushed inward to activate the nicotine housing assembly 300, the first O-ring 352a and the second O-ring 352b can move with the respective shafts of the first actuator 350a and the second actuator 350b inside respective openings in the second housing section 308 while maintaining their respective seals, thereby helping to reduce or prevent leakage of the nicotine-containing vapor formulation through the openings in the second housing section 308 for the first activation punch 314a and the second activation punch 314b. The first seal ring 352a and the second seal ring 352b may be formed from silicone.

The punch for the nicotine housing assembly 300 may include a recess configured to engage the clip to prevent premature activation of the punch. For example, the shafts of the first activation punch 314a and the second activation punch 314b may define a first recess 351a and a second recess 351b, respectively, configured to engage such a clamp. In an exemplary embodiment, the clip may have a planar structure defining a first slot and a second slot configured to engage the first recess 351a and the second recess 351b, respectively. When engaged with the shafts of the first activation punch 314a and the second activation punch 314b (via the first recess 351a and the second recess 351b, respectively), the clamp may be adjacent to the second housing section 308, thereby preventing the first activation punch 314a and/or the second activation punch 314b from being inadvertently depressed. into the accommodating element assembly 300 for nicotine. As a result, the first activation punch 314a and the second activation punch 314b can be suitably restrained (eg, during transport and/or handling) to reduce or prevent the possibility of their premature activation. The clip may be removed (eg, by an adult vaper) at an appropriate time when the nicotine housing assembly 300 is to be activated.

In fig. 28 is a perspective view of the connection module of FIG. 22 without wick and heater. In fig. 29 is an exploded view of the connection module of FIG. 28. In FIG. 30 is another exploded view of the connection module of FIG. 28. As shown in FIG. 28-30, the module housing 354 defines the frame of the connection module 320. The module housing 354 defines, among other things, the separator 329 and the flow path for air drawn into the nicotine housing assembly 300. Once assembled within the nicotine housing assembly 300, the downstream rim of the module housing 354 may be engaged with the upstream rim of the base portion 345a of the top cap holder 345 (eg, FIG. 26). As a result, the heater 336 and wick 338 (e.g., FIG. 22) may be enclosed (at least partially) within the module housing 354 and the top cap holder 345. In addition, the interior space defined by the module housing 354 and the top cap holder 345 when assembled form (within which the heater 336 and wick 338 are located), can be considered as a heating chamber. The heating chamber is in fluid communication with the flow path on the upstream side of the module housing 354 through the module outlet 368.

As noted above, the flow path for air drawn into the nicotine housing assembly 300 includes a first divergent portion, a second divergent portion, and a convergent portion defined by the module housing 354. In an exemplary embodiment, the first divergent portion and the second divergent portion are symmetrical portions bisected by an axis corresponding to the convergent portion of the flow path. For example, as shown in FIG. 30, the first divergent portion, the second divergent portion, and the convergent portion may comprise a first curved path 330a, a second curved path 330b, and a convergent path 330c, respectively. The first curved path 330a and the second curved path 330b may be substantially U-shaped paths, while the converging path 330c may be a substantially linear path. Based on the axis corresponding to the convergent path 330c and aligned with the crest of the divider 329, the first divergent portion of the flow path may be a mirror image of the second divergent portion of the flow path. During smoking of the e-cigarette, air drawn through the accommodating member inlet 322 may be separated by the separator 329 and initially flow in opposite directions from the separator 329, followed by parallel flow before each air stream makes a 180-degree turn (through the first curved path 330a and second curved path 330b) and converge (via converging path 330c) for the combined flow to flow back to separator 329 before passing through module outlet 368 into the heating chamber. Heater 336 and wick 338 may be positioned such that both sides are substantially equally exposed to air flow passing through module outlet 368. During smoking of the e-cigarette, the generated nicotine-containing vapor is carried away by the air flow passing through the heating chamber into the vapor passage 316.

A baffle 370 may be placed within the module outlet 368 to separate the flow of air entering the heating chamber. Heater 336 and wick 338 (e.g., FIG. 22) are located downstream of module outlet 368 and may be oriented to be aligned with baffle 370. Baffle 370 may divide air flow relatively equally so that the first flow passes along the first side of the heater 336 (and wick 338), while the second flow passes along the second side of the heater 336 (and wick 338). In an exemplary embodiment, the quantities (eg, velocity, volume flow, mass flow) of the first stream and the second stream may differ from each other within ±10 percent. For example, with respect to the air drawn into the heating chamber, 51 percent may be part of the first stream, while 49 percent may be part of the second stream, although it should be understood that variations within the above range may occur. In addition to reducing the flow imbalance through the heating chamber, the baffle 370 can also be considered a flow straightener.

The baffle 370 may be in the form of a bar that extends across the module outlet 368 (eg, bisecting it). In terms of dimensions, the partition 370 may have a thickness of approximately 150-250 micrometers (eg, 200 micrometers). The thickness of the baffle 370 corresponds to the extent to which the module outlet 368 is blocked by the baffle 370. Therefore, the thickness of the baffle 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) for the smoking device 500 e-cigarettes containing nicotine. Additionally, the width of the partition 370 can range from 525 to 875 micrometers (eg, 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. Additionally, if the module outlet 368 has a circular cross-section, the length of the baffle 370 may correspond to the diameter of the module outlet 368. Alternatively, in cases where the module outlet 368 has an elliptical cross-section, the length of the baffle 370 may correspond to an axis (eg, minor axis, major axis) of the module outlet 368.

As illustrated in FIG. 29-30, each of the first power contact 324a and the second power contact 324b may include a contact surface and a contact leg. The contact leg (which may have an elongated configuration) may be oriented orthogonal to the contact surface (which may be square-shaped), although exemplary embodiments are not limited to this. The module housing 354 may define a pair of shallow recesses and a pair of holes to facilitate mounting of the first power contact 324a and the second power contact 324b. During assembly, the contact surface of each of the first power contact 324a and the second power contact 324b may be seated in a respective one of a pair of shallow recesses so as to be substantially flush with the outer surface of the module housing 354 (eg, FIG. 21). In addition, a contact leg of each of the first power contact 324a and the second power contact 324b may extend through a respective one of the pair of holes so as to protrude from the downstream side of the module housing 354 (eg, FIG. 28). The heater 336 may subsequently be connected to a terminal leg of each of the first power terminal 324a and the second power terminal 324b.

Printed circuit board (PCB) 362 includes multiple data pins 326 on its upstream side (e.g., FIG. 30) and various electronic components, including a sensor 364, on its downstream side (e.g., FIG. 29) . Sensor 364 may be located on printed circuit board (PCB) 362 such that sensor 364 is located within a converging path 330c defined by module housing 354. In an exemplary embodiment, the printed circuit board (PCB) 362 (and associated components mounted thereon) is an independent structure that is initially inserted into a receiving cavity on the downstream side of the second housing section 308 such that the data pins 326 are visible through the data contact opening 327 of the second housing section 308. Thereafter, the module housing 354 (with the first power contact 324a, the second power contact 324b, the heater 336, and the wick 338 mounted thereon) can be inserted into the receiving cavity such that the first power contact 324a and the second power contact 324b are visible through the opening 325a for a first power contact and an opening 325b for a second power contact, respectively, of the second housing section 308. Alternatively, to simplify the two-step insertion process described above to a one-step insertion process, it should be understood that the printed circuit board (PCB) 362 (and associated components secured thereto) may be attached to the module housing 354 (e.g., to form a single integrated structure ) to cover the first curved path 330a, the second curved path 330b, the converging path 330c, and the module outlet 368.

As noted above, the module outlet 368 may be a resistive torque release (RTD) port. In such a configuration, the draw resistance of the nicotine-containing e-cigarette smoking device 500 can be adjusted by changing the size of the module outlet 368 (instead of changing the size of the accommodating member inlet 322). In an exemplary embodiment, the size of the module outlet 368 may be selected such that the draw resistance is 20-100 millimeters of water (eg, 25-50 millimeters of water). For example, a diameter of 1.0 millimeters for the module outlet 368 would result in a draw resistance of 88.3 millimeters of water. Alternatively, a diameter of 1.1 millimeters for the module outlet 368 would result in a draw resistance of 73.6 millimeters of water column. Alternatively, a diameter of 1.2 millimeters for the module outlet 368 would result in a draw resistance of 58.7 millimeters of water column. Alternatively, a diameter of 1.3 millimeters for the module outlet 368 may result in a draw resistance of approximately 40-43 millimeters of water column. Notably, the size of the module outlet 368, due to its internal layout, can be adjusted without affecting the aesthetic appearance of the nicotine housing assembly 300, thereby providing a more standardized product design for nicotine housing assemblies with varying draw resistances ( RTD), while reducing the chance of inadvertent blockage of incoming air.

Although a number of exemplary embodiments are disclosed herein, it should be understood that other variations may be possible. Such variations should not be construed as departing from the spirit and scope of the present invention, and all such modifications, as will be apparent to one skilled in the art, are intended to be included within the scope of the following claims.
