[0040] This document discloses several detailed example implementations. However, for the purpose of describing the example implementations, the specific structural and functional details disclosed herein are only representative. Furthermore, the example implementations can be implemented in many alternative forms and should not be construed as being limited to the example implementations described herein.

[0041] Therefore, while the exemplary embodiments can have various modifications and alternatives, they are shown as examples in the figures and will be described in detail herein. However, it should be understood that the exemplary embodiments are not intended to be limited to the specific forms disclosed; on the contrary, the exemplary embodiments will encompass all their modifications, equivalents, and alternatives. Throughout the description of the figures, similarity numbers indicate similar elements.

[0042] It should be understood that when an element or layer is referred to as being "on" another element or layer, "connected to," "attached to," "attached to," "adjacent to," or "covering" another element or layer, the element may be directly on, connected to, attached to, or cover the other element or layer, or there may be intermediate elements or layers present. In contrast, when an element is referred to as being "directly" on another element or layer, "directly connected to," or "directly attached to," there are no intermediate elements or layers present. Throughout this specification, similar designations refer to similar elements. As used herein, the term "and / or" includes any and all combinations or sub-combinations of one or more of the associated listed items.

[0043] It should be understood that while the terms first, second, third, etc., may be used herein to describe various elements, regions, layers, or segments, these elements, regions, layers, and / or segments should not be limited by these terms. These terms are used only to distinguish one element, region, layer, or segment from another. Therefore, without departing from the teachings of the example embodiments, the first element, region, layer, or segment discussed below may be referred to as the second element, region, layer, or segment.

[0044] For ease of description, spatial relative terms (e.g., “below,” “under,” “lower,” “above,” “upper,” etc.) are used herein to describe the relationship between one element or feature and another element or feature as shown in the figures. It should be understood that, in addition to the orientation depicted in the figures, the spatial relative terms are intended to cover different orientations of the device during use or operation. For example, if the device in the figure is flipped, then an element described as “below” or “under” other elements or features will be oriented “above” other elements or features. Therefore, the term “below” can include both “above” and “below” orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptive terms used herein are to be interpreted accordingly.

[0045] The terminology used herein is for the purpose of describing various exemplary embodiments only and is not intended to limit the exemplary embodiments. As used herein, the singular forms “a” and “described” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should be further understood that the terms “comprising” and / or “including”, when used in this specification, specify the presence of the stated features, integrals, steps, operations, and / or elements, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, and / or groups thereof.

[0046] When the terms “identical” or “equivalent” are used in the description of the example implementation, it should be understood that some imprecision may exist. Therefore, when an element or value is said to be identical to another element or value, it should be understood that the element or value is identical to the other element or value within a manufacturing or operational tolerance range (e.g., 10%).

[0047] When the terms “about” or “substantially” are used in conjunction with numerical values, it should be understood that the relevant numerical values ​​include manufacturing or operational tolerances (e.g., ±10%) near the stated values. Furthermore, when the terms “usually” and “substantially” are used in conjunction with geometry, it should be understood that precision of the geometry is not required, but the range of shapes is within the scope of this disclosure.

[0048] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the example embodiments pertain. It will be further understood that terms, including those as defined in commonly used dictionaries, shall be interpreted as having a meaning consistent with their meaning in the relevant field, and shall not be interpreted in an idealized or overly formalized sense unless expressly defined herein.

[0049] The hardware may use processing or control circuitry systems, such as, 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 one or more devices capable of responding to and executing instructions in a defined manner.

[0050] Figure 1 This is a front view of a nicotine electronic vaporizer according to an example implementation. Figure 2 Yes Figure 1 Side view of a nicotine electronic vaporizer. Figure 3 yes Figure 1 Rear view of a nicotine e-vaporizer. (Refer to...) Figure 1-3The nicotine e-vaping device 500 includes a device body 100 configured to receive a nicotine container assembly 300. The nicotine container assembly 300 is a modular article configured to contain a nicotine vapor pre-preparation. The nicotine vapor pre-preparation is a material or combination of materials that can be converted into nicotine vapor. For example, the nicotine vapor pre-preparation may include liquid, solid, and / or gel formulations. These may include, for example, but not limited to, water, oil, emulsion, beads, solvents, active ingredients, ethanol, plant extracts, nicotine, natural or artificial flavorings, vaporizing agents such as glycerin and propylene glycol, and / or any other ingredients suitable for inhalation. During vaporization, the nicotine e-vaping device 500 is configured to heat the nicotine vapor pre-preparation to produce nicotine vapor. Nicotine vapor, nicotine aerosol, and nicotine dispersion are used interchangeably to refer to a substance produced or output by the disclosed, claimed device and / or its equivalents, wherein such substance contains nicotine. The nicotine electronic vapor device 500 can be considered an electronic nicotine delivery system (ENDS).

[0051] like Figure 1 and Figure 3 As shown, the nicotine electronic vaporizer 500 extends in the longitudinal direction and its length is greater than its width. Furthermore, as... Figure 2 As shown, 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 can be greater than its thickness. Assuming an xyz Cartesian coordinate system, the length of the nicotine e-vaping device 500 can be measured in the y-direction, the width in the x-direction, and the thickness in the z-direction. Based on its front, side, and rear views, the nicotine e-vaping device 500 can have a basically linear form with tapered ends, but the example embodiment is not limited to this.

[0052] 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 the operation of the nicotine e-vaping device 500. For example, the device housing of the device body 100 may enclose a power source configured to supply current to the nicotine e-vaping device 500, which may include supplying current to the nicotine container assembly 300. Additionally, when assembled, the front cover 104, frame 106, and rear cover 108 may constitute a large portion of the visible portion of the device body 100. The device housing can 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 can be considered to form the device body 100.

[0053] A front cover 104 (e.g., a first cover) defines a main opening configured to receive a frame structure 112. The main opening may have a rounded rectangular shape, but other shapes are possible depending on the shape of the frame structure 112. The frame structure 112 defines a through-hole 150 configured to receive a nicotine container assembly 300. (This is in conjunction with examples...) Figure 9 Let's discuss the through-hole 150 in more detail.

[0054] The front cover 104 also defines a second opening configured to receive a light guide device. The second opening may resemble a slot (e.g., a segmented slot), but other shapes are possible depending on the shape of the light guide device. In an example embodiment, the light guide device includes a light guide lens 116. Furthermore, the front cover 104 defines a third and a fourth opening configured to receive a first button 118 and a second button 120. Each of the third and fourth openings may resemble a rounded square, but other shapes are possible depending on the shape of the button. A first button housing 122 is configured to expose a first button lens 124, while a second button housing 123 is configured to expose a second button lens 126.

[0055] The operation of the nicotine electronic vaporizer 500 can 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 shown in the accompanying drawings, it should be understood that more (or fewer) buttons may be provided depending on the available features and desired user interface.

[0056] Frame 106 (e.g., base frame) is the central support structure of the device body 100 (and the nicotine e-vaping device 500 as a whole). Frame 106 may be referred to as a chassis. 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 referred to as the downstream end and the upstream end, respectively. As used herein, "proximal end" (and conversely, "distal end") refers to the adult vaporizer during vaporization, while "downstream" (and conversely, "upstream") refers to the flow of nicotine vapor. To increase strength and stability, bridging sections (e.g., approximately at the midpoint along the length of frame 106) may be provided between the opposing inner surfaces of the side sections. Frame 106 may be integrally formed, thus becoming a monolithic structure.

[0057] Regarding the construction material, frame 106 can be formed of alloy or plastic. The alloy (e.g., die-casting grade, machinable grade) can be an aluminum (Al) alloy or a zinc (Zn) alloy. The plastic can be polycarbonate (PC), acrylonitrile butadiene styrene (ABS), or a combination thereof (PC / ABS). For example, polycarbonate can be LUPOY SC1004A. Furthermore, for functional and / or aesthetic reasons, frame 106 can have a surface finish (e.g., to provide a premium appearance). In an example embodiment, frame 106 (e.g., when formed of an aluminum alloy) can be anodized. In another embodiment, frame 106 (e.g., when formed of a zinc alloy) can be coated with hard enamel or painted. In another embodiment, frame 106 (e.g., when formed of polycarbonate) can be metallized. In yet another embodiment, frame 106 (e.g., when formed of acrylonitrile butadiene styrene) can be electroplated. It should be understood that the construction materials of frame 106 can also be applied to the front cover 104, rear cover 108 and / or other suitable parts of the nicotine electronic vaporizer 500.

[0058] The rear cover 108 (e.g., a second cover) also defines an opening configured to receive the frame structure 112. This opening may have a rounded rectangular shape, but other shapes are possible depending on the shape of the frame structure 112. In the example embodiment, the opening in the rear cover 108 is smaller than the main opening in the front cover 104. Furthermore, although not shown, it should be understood that a light guide and / or button may be provided on the rear of the nicotine e-vaping device 500 to complement (or replace) the light guide and button on the front of the nicotine e-vaping device 500.

[0059] The front cover 104 and rear cover 108 can be configured to engage with the frame 106 via a snap-fit ​​arrangement. For example, the front cover 104 and / or rear cover 108 may include clamps configured to interlock with corresponding mating members of the frame 106. In a non-limiting embodiment, the clamp may be in the form of a tab with an opening configured to receive a corresponding mating member of the frame 106 (e.g., a protrusion with a beveled edge). Alternatively, the front cover 104 and / or rear cover 108 may be configured to engage with the frame 106 by an interference fit (also referred to as a press fit or friction fit). However, it should be understood that the front cover 104, frame 106, and rear cover 108 can be coupled by other suitable arrangements and techniques.

[0060] The main body 100 of the device also includes a mouthpiece 102. The mouthpiece 102 can be fixed to the proximal end of the frame 106. Additionally, as... Figure 2As shown, in an example embodiment where the frame 106 is sandwiched between the front cover 104 and the rear cover 108, the mouthpiece 102 may be adjacent to 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.

[0061] Figure 4 Yes Figure 1 A near-end view of a nicotine electronic vaporizer. (Refer to...) Figure 4 The outlet surface of the mouthpiece 102 defines multiple steam outlets. In a non-limiting embodiment, the outlet surface of the mouthpiece 102 may be elliptical. 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. Moreover, the first and second crossbars may intersect perpendicularly and are integral parts of the mouthpiece 102. Although the outlet surface is shown defining four steam outlets, it should be understood that the example embodiment is not limited thereto. For example, the outlet surface may define fewer than four (e.g., one, two) steam outlets or more than four (e.g., six, eight) steam outlets.

[0062] Figure 5 yes Figure 1 A view of the distal end of a nicotine electronic vaporizer. (Refer 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 send data to and / or receive data from another nicotine e-vaping device or other electronic device (e.g., a telephone, tablet, or computer) (e.g., via a USB / mini-USB cable). Additionally, the nicotine e-vaping device 500 may be configured to wirelessly communicate with another electronic device (e.g., a telephone) via an application (app) installed on that device. In this case, the adult vaper can control or otherwise interact with the nicotine e-vaping device 500 (e.g., locate the nicotine e-vaping device, check usage information, or change operating parameters) through the application.

[0063] Figure 6 yes Figure 1 A perspective view of a nicotine electronic vaporizer. Figure 7 yes Figure 6 A magnified view of the container inlet. (See reference) Figure 6-7And as briefly mentioned above, the nicotine e-vapor device 500 includes a nicotine container assembly 300 configured to contain a nicotine pre-vaporized blend. The nicotine container assembly 300 has an upstream end (facing the light guide device) and a downstream end (facing the mouthpiece 102). In a non-limiting embodiment, the upstream end is the surface of the nicotine container assembly 300 opposite the downstream end. The upstream end of the nicotine container assembly 300 defines a container inlet 322. The device body 100 defines a through-hole (e.g., Figure 9 The through-hole 150 is configured to receive the nicotine container assembly 300. In an example embodiment, the frame structure 112 of the device body 100 defines the through-hole and includes an upstream edge. As shown, particularly in Figure 7 In the middle, the upstream edge of the frame structure 112 is angled (e.g., tilted inward) so as to expose the container inlet 322 when the nicotine container assembly 300 is placed in the through hole of the device body 100.

[0064] For example, the upstream edge of the frame structure 112 is configured as a concave scoop to guide ambient air into the container inlet 322, rather than following the shape of the front cover 104 (so as to be flush with the front of the nicotine container assembly 300 and thus shield the container inlet 322). This angled / concave scoop configuration (e.g., it may be curved) can help reduce or prevent clogging of the air inlet (e.g., container inlet 322) of the nicotine e-vapor device 500. The depth of the concave scoop can expose less than half (e.g., less than a quarter) of the upstream end face of the nicotine container assembly 300. Alternatively, in a non-limiting embodiment, the container 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 can be considered to extend in a second direction, wherein the second direction is transverse to the first direction.

[0065] Figure 8 yes Figure 6 A cross-sectional view of a nicotine electronic vaporizer. Figure 8 In the figure, the cross-section is taken along the longitudinal axis of the nicotine e-vaping device 500. As shown, the device body 100 and the nicotine container assembly 300 include mechanical components, electronic components, and / or circuitry associated with the operation of the nicotine e-vaping device 500, which will be discussed in more detail herein and / or incorporated herein by reference. For example, the nicotine container assembly 300 may include mechanical components configured to actuate to release nicotine vapor pre-formulated liquid from a sealed reservoir therein. The nicotine container assembly 300 may also have mechanical features configured to engage with the device body 100 to facilitate insertion and placement of the nicotine container assembly 300.

[0066] Furthermore, the nicotine container assembly 300 can be a "smart container," comprising electronic components and / or circuitry configured to store, receive, and / or transmit information to / from the device body 100. This information can be used to verify the nicotine container assembly 300 used with the device body 100 (e.g., to prevent the use of unapproved / counterfeit nicotine container assemblies). Additionally, this information can be used to identify the type of nicotine container assembly 300, and then associate that type with a vaporization profile based on the identified type. The vaporization profile can be designed to specify general parameters for the pre-mixed nicotine vapor and can be adjusted, refined, or otherwise modified by the adult vaporizer before and / or during vaporization.

[0067] The nicotine container assembly 300 may also communicate with the device body 100 other information that may be relevant to the operation of the nicotine e-vaping device 500. Examples of such information may include the level of nicotine pre-vaping formulation within the nicotine container assembly 300 and / or the length of time that has elapsed since the nicotine container assembly 300 was inserted into the device body 100 and activated. For example, if the nicotine container assembly 300 was inserted into the device body 100 and activated more than a certain period of time ago (e.g., more than 6 months ago), the nicotine e-vaping device 500 may not allow vaping, and the adult vaper may be prompted to replace the nicotine container assembly even if the nicotine container assembly 300 still contains a sufficient level of nicotine pre-vaping formulation.

[0068] The device body 100 may include mechanical components (e.g., complementary structures) configured to engage, hold, and / or activate the nicotine container assembly 300. Furthermore, the device body 100 may include electronic components and / or circuitry configured to receive current to charge an internal power source (e.g., a battery), which in turn is configured to supply power to the nicotine container assembly 300 during vaporization. Additionally, the device body 100 may include electronic components and / or circuitry configured to communicate with the nicotine container assembly 300, different nicotine e-vaping devices, other electronic devices (e.g., telephones, tablets, computers), and / or the adult vaper. The transmitted information may include container-specific data, current vaping details, and / or past vaping patterns / history. Such communication may be communicated to the adult vaper using tactile (e.g., vibration), auditory (e.g., beeping), and / or visual (e.g., colored / flashing lights) feedback. Charging and / or information transmission may be performed using port 110 (e.g., via a USB / mini-USB cable).

[0069] Figure 9 yes Figure 6 A perspective view of the main body of a nicotine electronic vaporizer. (Refer to...) Figure 9 The frame structure 112 of the device body 100 defines a through-hole 150. The through-hole 150 is configured to receive a nicotine container assembly 300. To facilitate insertion and placement of the nicotine container assembly 300 within the through-hole 150, the upstream edge of the frame structure 112 includes a first upstream protrusion 128a and a second upstream protrusion 128b. The through-hole 150 may have a rectangular shape with rounded corners. In an example embodiment, the first upstream protrusion 128a and the second upstream protrusion 128b are integrally formed with the frame structure 112 and located at the two rounded corners of the upstream edge.

[0070] The downstream sidewall of the frame structure 112 may define a first downstream opening, a second downstream opening, and a third downstream opening. A retaining structure including a first downstream protrusion 130a and a second downstream protrusion 130b engages with the frame structure 112 such that the first downstream protrusion 130a and the second downstream protrusion 130b protrude through the first downstream opening and the second downstream opening of the frame structure 112, respectively, and enter the through hole 150. Additionally, the distal end of the mouthpiece 102 extends through the third downstream opening of the frame structure 112 and enters the through hole 150, positioned between the first downstream protrusion 130a and the second downstream protrusion 130b.

[0071] Figure 10 yes Figure 9 A front view of the main body of the device. (Refer to...) Figure 10 The device body 100 includes a device electrical connector 132 disposed upstream of the through-hole 150. The device electrical connector 132 of the device body 100 is configured to electrically engage with a nicotine container assembly 300 disposed within the through-hole 150. As a result, during vaporization, power can be supplied from the device body 100 to the nicotine container assembly 300 via the device electrical connector 132. Furthermore, data can be sent to and / or received from the device body 100 and the nicotine container assembly 300 via the device electrical connector 132.

[0072] Figure 11 yes Figure 10 Enlarged perspective view of the through-hole. (Refer to...) Figure 11The 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 embodiment, the first upstream protrusion 128a and the second upstream protrusion 128b are fixed structures (e.g., fixed pivots), while the first downstream protrusion 130a and the second downstream protrusion 130b are retractable structures (e.g., retractable members). For example, the first downstream protrusion 130a and the second downstream protrusion 130b can be configured (e.g., spring-loaded) to default to an extended state, while also being configured to temporarily transition to a retracted state (and reversibly return to the extended state) to facilitate insertion of the nicotine container assembly 300.

[0073] Specifically, when the nicotine container assembly 300 is inserted into the through-hole 150 of the device body 100, the recess at the upstream end face of the nicotine container assembly 300 can initially engage with the first upstream protrusion 128a and the second upstream protrusion 128b. Subsequently, the nicotine container assembly 300 pivots (around the first upstream protrusion 128a and the second upstream protrusion 128b) until the recess at the downstream end face of the nicotine container assembly 300 engages with the first downstream protrusion 130a and the second downstream protrusion 130b. In this case, the axis of rotation of the nicotine container assembly 300 (during pivoting) can be orthogonal to the longitudinal axis of the device body 100. Additionally, the first downstream protrusion 130a and the second downstream protrusion 130b can be biased for retraction, retracting when the nicotine container assembly 300 pivots into the through-hole 150 and elastically extends to engage with the recess at the downstream end face of the nicotine container assembly 300. Furthermore, the engagement of the first downstream protrusion 130a and the second downstream protrusion 130b with the recess at the downstream end face of the nicotine container assembly 300 can generate tactile and / or auditory feedback (e.g., an audible click) to notify the adult vapor user that the nicotine container assembly 300 is correctly positioned in the through-hole 150 of the device body 100.

[0074] Figure 12 yes Figure 10 Enlarged perspective view of the device electrical contacts. The device electrical contacts of the device body 100 are configured to engage with the container electrical contacts of the nicotine container assembly 300 when the nicotine container assembly 300 is placed within the through-hole 150 of the device body 100. (Refer to...) Figure 12The device body 100 includes a device electrical connector 132 as its electrical contacts. 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 container assembly 300. As shown, the power contacts of the device electrical connector 132 include a first power contact and a second power contact (they are positioned closer to the front cover 104 than the rear cover 108). The first power contact (e.g., the power contact adjacent to the first upstream protrusion 128a) may be a single integral structure different from the second power contact and includes a protrusion extending into the through-hole 150 during assembly. Similarly, the second power contact (e.g., the power contact adjacent to the second upstream protrusion 128b) may be a single integral structure different from the first power contact and includes a protrusion extending into the through-hole 150 during assembly. The first and second power contacts of the device electrical connector 132 can be retractably mounted and biased to extend into the through-hole 150 by default and retract from the through-hole 150 (e.g., independently) when subjected to a force that overcomes the bias.

[0075] The data contacts of the device electrical connector 132 are configured to transmit data between the nicotine container assembly 300 and the device body 100. As shown, the data contacts of the device electrical connector 132 include a row of five protrusions (positioned closer to the rear cover 108 than the front cover 104). The data contacts of the device electrical connector 132 can have different structures that extend into the through-hole 150 when assembled. The data contacts of the device electrical connector 132 can also be retractably mounted and biased (e.g., via a serpentine structure and / or by a spring) to extend into the through-hole 150 by default and retract from the through-hole 150 when subjected to a force overcoming the bias (e.g., independently). For example, when the nicotine container assembly 300 is inserted into the through-hole 150 of the device body 100, the container electrical contacts of the nicotine container assembly 300 will press 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 will retract (e.g., at least partially) into the device body 100, but due to their resilient arrangement, they will continue to push against the corresponding container electrical contacts, thereby helping to ensure a proper electrical connection between the device body 100 and the nicotine container assembly 300. Furthermore, this connection can also be mechanically safe and have minimal contact resistance, allowing reliable and accurate transmission and / or delivery of power and / or signals between the device body 100 and the nicotine container assembly 300. While various aspects have been discussed in conjunction with the device electrical contacts of the device body 100, it should be understood that the example embodiment is not limited thereto, and other configurations may be utilized.

[0076] Figure 13 It includes Figure 12 A partial exploded view of the cigarette holder. (Refer to...) Figure 13 The mouthpiece 102 is configured to engage with the device housing via a retaining structure 140. In an example embodiment, the retaining structure 140 is located primarily between the frame 106 and the side frame structure 112. As shown, the retaining structure 140 is disposed 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 or substantially flush with the proximal end of the frame 106. 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 concave, while the distal end of the mouthpiece may be convex.

[0077] For example, the mouthpiece 102 can be bayoneted (e.g., reversibly) to the retaining structure 140. In this case, the concave end of the retaining structure 140 can define a pair of opposing L-shaped grooves, while the convex end of the mouthpiece 102 can have opposing radial members 134 (e.g., radial pins) configured to engage with the L-shaped grooves of the retaining structure 140. Each L-shaped groove of the retaining structure 140 can have a longitudinal portion and a circumferential portion. Optionally, the end of the circumferential portion can have a serif portion to help reduce or prevent the possibility of accidental disengagement of the radial members 134 of the mouthpiece 102. In a non-limiting embodiment, the longitudinal portion of the L-shaped groove extends parallel to and along the longitudinal axis of the device body 100, while the circumferential portion of the L-shaped groove extends about the longitudinal axis (e.g., the central axis) of the device body 100. Thus, in order to attach the mouthpiece 102 to the device housing, Figure 13 The mouthpiece 102 shown is initially rotated 90 degrees to align the radial member 134 with the inlet of the longitudinal portion of the L-shaped groove of the retaining structure 140. The mouthpiece 102 is then pushed into the retaining structure 140 such that the radial member 134 slides along the longitudinal portion of the L-shaped groove until it reaches engagement with each circumferential portion. At this point, the mouthpiece 102 is then rotated such that the radial member 134 passes through the circumferential portion until it reaches the end point of each. With a serif portion present at each end, tactile and / or auditory feedback (e.g., an audible click) can be generated to notify the adult vaporizer that the mouthpiece 102 has been correctly engaged with the device housing.

[0078] Mouthpiece 102 defines a vapor passage 136 through which nicotine vapor flows during vaping. Vapor passage 136 is in fluid communication with through-hole 150 (where the nicotine container assembly 300 is located within the device body 100). The proximal end of vapor passage 136 may include a flared portion. Additionally, mouthpiece 102 may include an end cap 138. End cap 138 tapers from its distal end to its proximal end. The outlet face of end cap 138 defines a plurality of vapor outlets. Although four vapor outlets are shown in end cap 138, it should be understood that the exemplary embodiment is not limited thereto.

[0079] Figure 14 It includes Figure 9 A partial exploded view of the border structure in the image. Figure 15 yes Figure 14 Enlarged perspective view of the mouthpiece, spring, retaining structure, and frame structure. (Refer to...) Figure 14-15 The frame structure 112 includes an upstream sidewall and a downstream sidewall. The upstream sidewall of the frame structure 112 defines a connector opening 146. The connector opening 146 is configured to expose or receive a device electrical connector 132 of the device body 100. The downstream sidewall of the frame 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 frame structure 112 are configured to receive a first downstream protrusion 130a and a second downstream protrusion 130b of the retaining structure 140, respectively. The third downstream opening 148c of the frame structure 112 is configured to receive a distal end of the mouthpiece 102.

[0080] like Figure 14 As shown, the first downstream protrusion 130a and the second downstream protrusion 130b are on the concave side of the retaining structure 140. Figure 15 As shown, the first post 142a and the second post 142b are on opposite convex sides of the retaining structure 140. The first spring 144a and the second spring 144b are respectively disposed on the first post 142a and the second post 142b. The first spring 144a and the second spring 144b are configured to bias the retaining structure 140 against the frame structure 112.

[0081] During assembly, the frame structure 112 can be secured to the frame 106 via a pair of posts on the underside of the upstream edge of the frame structure 112 and adjacent to the connector opening 146. Additionally, the retaining structure 140 will abut the frame structure 112 such that a first downstream protrusion 130a and a second downstream protrusion 130b extend through the first downstream opening 148a and the second downstream opening 148b, respectively. The mouthpiece 102 will be coupled 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 frame structure 112. A first spring 144a and a second spring 144b will be positioned between the frame 106 and the retaining structure 140.

[0082] When the nicotine container assembly 300 is inserted into the through-hole 150 of the device body 100, the downstream end 300 of the nicotine container assembly will push against 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 elastically yield and retract from the through-hole 150 of the device body 100 (by means of the compression of the first spring 144a and the second spring 144b), thereby allowing continued insertion of the nicotine container assembly 300. In an example 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, the displacement of the retaining structure 140 allows the ends of the first post 142a and the second post 142b to contact the inner end surface of the frame 106. Furthermore, since the mouthpiece 102 is connected to the retaining structure 140, the distal end of the mouthpiece 102 will retract from the through hole 150, thus causing the proximal end of the mouthpiece 102 (e.g., including the visible portion of the end cap 138) to also be displaced a corresponding distance away from the device housing.

[0083] Once the nicotine container assembly 300 is fully inserted, such that the first and second downstream recesses of the nicotine container assembly 300 reach positions that allow engagement with the first and second downstream protrusions 130a and 130b, respectively, the energy stored by the compression of the first and second springs 144a and 144b will cause the first and second downstream protrusions 130a and 130b to elastically extend and engage with the first and second downstream recesses of the nicotine container assembly 300, respectively. Furthermore, engagement can produce tactile and / or auditory feedback (e.g., an audible click) to notify the adult vapor user that the nicotine container assembly 300 is properly positioned within the through-hole 150 of the device body 100.

[0084] Figure 16 It includes Figure 14 A partial exploded view of the front cover, frame, and rear cover. (Refer to...) Figure 16 Various mechanical, electronic, and / or circuitry components associated with the operation of the nicotine e-vaping device 500 can be secured to the frame 106. The front cover 104 and rear cover 108 can be configured to engage with the frame 106 via a snap-fit ​​arrangement. In an example embodiment, the front cover 104 and rear cover 108 include clamps configured to interlock with corresponding mating members of the frame 106. The clamps can be in the form of tabs with orifices configured to receive corresponding mating members of the frame 106 (e.g., protrusions with beveled edges). Figure 16In the case of the front cover 104, there are two rows of four clamps per row (a total of eight clamps for the front cover 104). Similarly, the rear cover 108 has two rows of four clamps per row (a total of eight clamps for the rear cover 108). The corresponding mating members of the frame 106 can be on the inner sidewall of the frame 106. As a result, when the front cover 104 and the rear cover 108 are fastened together, the engaging clamps and mating members can be concealed and not visible. Alternatively, the front cover 104 and / or the rear cover 108 can be configured to engage with the frame 106 via an interference fit. However, it should be understood that the front cover 104, the frame 106, and the rear cover 108 can be connected by other suitable arrangements and techniques.

[0086] Figure 18 yes Figure 17 Another perspective view of the nicotine container components. Figure 19 yes Figure 18 Another perspective view of the nicotine container assembly. (See reference) Figure 17-19 A nicotine container assembly 300 for a nicotine e-vapor device 500 includes a container body configured to contain a nicotine vapor pre-formulation. The container body has an upstream end and a downstream end. The upstream end of the container body defines a container inlet 322. The downstream end of the container body defines a container outlet 304 in fluid communication with the container inlet 322 at the upstream end. During vaporization, air enters the nicotine container assembly 300 via the container inlet 322, and nicotine vapor exits the nicotine container assembly 300 via the container outlet 304. The container inlet 322 is shown in the figures as a trough. However, it should be understood that the exemplary embodiment is not limited thereto, and other forms are possible.

[0087] Nicotine container assembly 300 includes connector module 320 (e.g., Figure 21 The connector module is disposed within the container body and exposed by an opening in the upstream end. The outer surface of the connector module 320 includes at least one electrical contact. The at least one electrical contact may include 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 container assembly 300 is configured to connect with the first power contact of the device electrical connector 132 of the device body 100 (e.g., adjacent to...). Figure 12 The first upstream protrusion 128a of the nicotine container assembly 300 is electrically connected to the power contact of the device connector 132 of the device body 100 (e.g., adjacent to the power contact of the first upstream protrusion 128a). Similarly, the second power contact 324b of the nicotine container assembly 300 is configured to connect to the second power contact of the device electrical connector 132 of the device body 100 (e.g., adjacent to the power contact of the first upstream protrusion 128a). Figure 12The second upstream protrusion 128b in the nicotine container assembly 300 is electrically connected to the power contact. Furthermore, at least one electrical contact of the nicotine container assembly 300 includes a plurality of data contacts 326. The plurality of data contacts 326 of the nicotine container assembly 300 are configured to connect with the data contacts of the device electrical connector 132 (e.g., ...). Figure 12 The electrical connections are a row of contacts without protrusions. Although two electrical contacts and five data contacts associated with the nicotine container assembly 300 are shown, it should be understood that other variations are possible depending on the design of the device body 100.

[0088] In an example implementation, the nicotine container assembly 300 includes a front side, a back side opposite the front side, a first side side between the front and back sides, a second side side opposite the first side side, an upstream end face, and a downstream end face opposite the upstream end face. The corners of the sides and end faces (e.g., the corner between the first side side and the upstream end face, the corner between the upstream end face and the second side side, the corner between the second side side and the downstream end face, and the corner between the downstream end face and the first side side) may be rounded. However, in some cases, the corners may be angled. Furthermore, the peripheral edge of the front side may be in the form of a flange. The outer surface of the connector module 320 (exposed by the container body) can be considered part of the upstream end face of the nicotine container assembly 300. The front side of the nicotine container assembly 300 may be wider and longer than the back side. In this case, the first and second side sides may be angled inwards towards each other. The upstream and downstream end faces may also be angled inwards towards each other. Due to the angled surfaces, insertion of the nicotine container assembly 300 will be unidirectional (e.g., 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 container assembly 300 being incorrectly inserted into the device body 100 can be reduced or prevented.

[0089] As shown in the figure, the container body of the nicotine container assembly 300 includes a first housing segment 302 and a second housing segment 308. The first housing segment 302 has a downstream end defining a container outlet 304. The edge of the container outlet 304 may optionally be a recessed or recessed area. In this case, the area may resemble a recess, wherein the side of the edge adjacent to the back of the nicotine container assembly 300 can be opened, while the side of the edge adjacent to the front can be surrounded by a protrusion at the downstream end of the first housing segment 302. The protrusion may act as a stop for the distal end of the mouthpiece 102. As a result, this configuration of the container outlet 304 can facilitate receiving and aligning the distal end of the mouthpiece 102 (e.g., via the open side of the edge) Figure 11This facilitates its subsequent placement against a protrusion at the downstream end of the first housing section 302. In a non-limiting embodiment, when the nicotine container assembly 300 is properly inserted into the through-hole 150 of the device body 100, the distal end of the mouthpiece 102 may also include an elastic material (or be formed of an elastic material) to facilitate the formation of a seal around the container outlet 304.

[0090] The downstream end of the first housing section 302 further defines at least one downstream recess. In an example embodiment, the at least one downstream recess is in the form of a first downstream recess 306a and a second downstream recess 306b. The container 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 protrusion 130a and a second downstream protrusion 130b of the device body 100, respectively. Figure 11 As shown, the first downstream protrusion 130a and the second downstream protrusion 130b of the device body 100 can be disposed on adjacent corners of the downstream sidewall of the through hole 150. The first downstream recess 306a and the second downstream recess 306b can each be in the form of a V-shaped notch. In this case, each of the first downstream protrusion 130a and the second downstream protrusion 130b of the device body 100 can be in the form of a wedge structure, which is configured to engage with the corresponding V-shaped notch in the first downstream recess 306a and the second downstream recess 306b. The first downstream recess 306a can abut the corner and the first side of the downstream end face, while the second downstream recess 306b can abut the corner and the second side of the downstream end face. As a result, the edges of the first and second side faces of the first downstream recess 306a and the second downstream recess 306b can be opened respectively. In this case, as Figure 18 As shown, each of the first downstream recess 306a and the second downstream recess 306b can be a three-sided recess.

[0091] The second housing section 308 has an upstream end that further defines (in addition to the container inlet 322) a plurality of openings (e.g., a first electrical contact opening 325a, a second electrical contact opening 325b, and a data contact opening 327), which are configured to expose the connector module 320 within the nicotine container assembly 300. Figure 20-21 The upstream end of the second housing section 308 defines at least one upstream recess. In an example embodiment, the at least one upstream recess is in the form of a first upstream recess 312a and a second upstream recess 312b. A container 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 a first upstream protrusion 128a and a second upstream protrusion 128b of the device body 100, respectively. Figure 12As shown, the first upstream protrusion 128a and the second upstream protrusion 128b of the device body 100 can be disposed on adjacent corners of the upstream sidewall of the through hole 150. The depth of each of the first upstream recess 312a and the second upstream recess 312b can be greater than the depth of each of the first downstream recess 306a and the second downstream recess 306b. The end of each of the first upstream recess 312a and the second upstream recess 312b can also be more rounded than the end 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 can each be in the form of a U-shaped indentation. In this case, each of the first upstream protrusion 128a and the second upstream protrusion 128b of the device body 100 can be in the form of a circular knob, which is configured to engage with the corresponding U-shaped indentation in the first upstream recess 312a and the second upstream recess 312b. The first upstream recess 312a may be adjacent to the corner and the first side surface of the upstream end face, while the second upstream recess 312b may be adjacent to the corner and the second side surface of the upstream end face. As a result, the edges of the first and second side surfaces adjacent to the first and second upstream recesses 312a and 312b, respectively, can be opened.

[0092] The first housing section 302 may define therein a reservoir configured to contain a nicotine vapor pre-preparation. The reservoir may be configured to hermetically seal the nicotine vapor pre-preparation until the nicotine container assembly 300 is activated to release the nicotine vapor pre-preparation from the reservoir. As a result of the hermetically sealed design, the nicotine vapor pre-preparation may be isolated from the environment and from the internal components of the nicotine container assembly 300 that may potentially react with the nicotine vapor pre-preparation, thereby reducing or preventing the possibility of adverse effects on the shelf life and / or sensory properties (e.g., taste) of the nicotine vapor pre-preparation. The second housing section 308 may include a structure configured to activate the nicotine container assembly 300 and, upon activation, receive and heat the nicotine vapor pre-preparation released from the reservoir.

[0093] The nicotine container assembly 300 can be manually activated by an adult vaporizer before insertion into the device body 100. Alternatively, the nicotine container assembly 300 can be activated as part of insertion into the device body 100. In an example embodiment, the second housing section 308 of the container body includes a perforator configured to release nicotine vapor pre-formulation from a reservoir in the first housing section 302 during activation of the nicotine container assembly 300. The perforator may take the form of a first activation pin 314a and a second activation pin 314b, which will be discussed in more detail herein.

[0094] To manually activate the nicotine container assembly 300, an adult vapor user can press the first activation pin 314a and the second activation pin 314b inward (e.g., simultaneously or sequentially) before inserting the nicotine container 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 can be manually pressed until their ends are substantially flush with the upstream end face of the nicotine container assembly 300. In an example embodiment, inward movement of the first activation pin 314a and the second activation pin 314b causes the seal of the reservoir to be punctured or otherwise damaged, thereby releasing the nicotine vapor pre-formulated therefrom.

[0095] Alternatively, as part of inserting the nicotine container assembly 300 into the device body 100, in order to activate the nicotine container assembly 300, the nicotine container assembly 300 is initially positioned such that the first upstream recess 312a and the second upstream recess 312b engage with the first upstream protrusion 128a and the second upstream protrusion 128b, respectively (e.g., upstream engagement). Since each of the first upstream protrusion 128a and the second upstream protrusion 128b of the device body 100 can be in the form of a circular knob configured to engage with a corresponding U-shaped notch in the first upstream recess 312a and the second upstream recess 312b, the nicotine container assembly 300 can then be relatively easily pivoted into the through-hole 150 of the device body 100 about the first upstream protrusion 128a and the second upstream protrusion 128b.

[0096] Regarding the pivoting of the nicotine container assembly 300, the axis of rotation can be considered to extend through the first upstream protrusion 128a and the second upstream protrusion 128b and be orthogonal to the longitudinal axis of the device body 100. During the initial positioning and subsequent pivoting of the nicotine container assembly 300, as the nicotine container assembly 300 enters the through-hole 150, the first actuating pin 314a and the second actuating pin 314b will contact the upstream sidewall of the through-hole 150 and will change from an extended state to a retracted state when the first actuating pin 314a and the second actuating pin 314b are pushed into (e.g., simultaneously) the second housing section 308. When the downstream end of the nicotine container assembly 300 reaches the vicinity of the downstream sidewall of the through-hole 150 and contacts the first downstream protrusion 130a and the second downstream protrusion 130b, the first downstream protrusion 130a and the second downstream protrusion 130b of the positioning allowable device body 100 engage (e.g., downstream engagement) with the first downstream recess 306a and the second downstream recess 306b of the nicotine container assembly 300, respectively. The first downstream protrusion 130a and the second downstream protrusion 130b will retract and then elastically extend (e.g., springback).

[0097] As described above, according to the example embodiment, the mouthpiece 102 is secured to the retaining structure 140 (of which the first downstream protrusion 130a and the second downstream protrusion 130b are part). In this case, the retraction of the first downstream protrusion 130a and the second downstream protrusion 130b from the through-hole 150 will cause the mouthpiece 102 to simultaneously shift by a corresponding distance in the same direction (e.g., downstream direction). Conversely, when the nicotine container assembly 300 has been fully inserted for downstream engagement, the mouthpiece 102 will rebound simultaneously with the first downstream protrusion 130a and the second downstream protrusion 130b. When the nicotine container assembly 300 is properly positioned within the through-hole 150 of the device body 100, 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 configured to be biased against the nicotine container assembly 300 (and aligned with the container outlet 304 to form a relatively airtight seal).

[0098] Furthermore, downstream engagement can produce an audible click and / or tactile feedback to indicate that the nicotine container assembly 300 is correctly positioned within the through-hole 150 of the device body 100. When correctly positioned, the nicotine container assembly 300 will be mechanically, electrically, and fluidly connected to the device body 100. Although the non-limiting embodiments described herein depict upstream engagement of the nicotine container assembly 300 occurring prior to downstream engagement, it should be understood that the associated mating, activation, and / or electrical arrangements can be reversed, such that downstream engagement occurs prior to upstream engagement.

[0099] Figure 20 yes Figure 19 A partial exploded view of the nicotine container components. (See reference...) Figure 20The first housing section 302 includes a vapor passage 316. The vapor passage 316 is configured to receive nicotine vapor generated during vaporization and is in fluid communication with a container outlet 304. In an example embodiment, the dimensions (e.g., diameter) of the vapor passage 316 gradually increase as it extends toward the container outlet 304. Furthermore, the vapor passage 316 may be integrally formed with the first housing section 302. An insert 342 and a seal 344 are disposed at the upstream end of the first housing section 302 to define a reservoir for the nicotine container assembly 300. For example, the insert 342 may be disposed within the first housing section 302 such that the peripheral surface of the insert 342 engages along an edge (e.g., via an interference fit) with the inner surface of the first housing section 302, 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 air-tight). Furthermore, seal 344 is attached to the upstream side of insert 342 to close the reservoir outlet in insert 342, so as to provide fluid seal (e.g., liquid seal and / or air seal) reception of the nicotine vapor pre-mixed material in the reservoir. Insert 342 and seal 344 also Figure 24 As shown in the figure, and will be discussed in more detail in this article.

[0100] The upstream end of the second housing section 308 defines a container inlet 322, a first electrical contact opening 325a, a second electrical 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 container inlet 322 allows air to enter the nicotine container assembly 300 during vaporization, while the first electrical contact opening 325a, the second electrical contact opening 325b, and the data contact opening 327 are configured to expose the first electrical contact 324a, the second electrical contact 324b, and the data contact 326 of the connector module 320, respectively. In an example embodiment, the first electrical contact 324a and the second electrical contact 324b are mounted on the module housing 354 of the connector module 320. Additionally, the data contact 326 may be disposed on a printed circuit board (PCB) 362. Furthermore, the container inlet 322 may be located between the first upstream recess 312a and the second upstream recess 312b, while the contact openings (e.g., the first electrical contact opening 325a, the second electrical 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 start pin 314a and the second start pin 314b extending therethrough, respectively.

[0101] Figure 21 yes Figure 20 A perspective view of the connector module. Figure 22 yes Figure 21 Another perspective view of the connector module. (Refer to...) Figure 21-22 The overall frame of connector module 320 includes module housing 354. Additionally, connector module 320 has multiple surfaces, including an outer surface and side surfaces adjacent to the outer surface. In an example embodiment, the outer surface of connector module 320 is formed by module housing 354, first power contact 324a, second power contact 324b, data contact 326, and the upstream surface of printed circuit board (PCB) 362. The side surfaces of connector module 320 may be integral parts of module housing 354 and are generally orthogonal to the outer surface.

[0102] The nicotine container assembly 300 defines a flow path from the container inlet 322 to the container outlet 304. The flow path through the nicotine container assembly 300 specifically includes a first branch section, a second branch section, and a converging section. The container inlet 322 is upstream of the first and second branch sections of the flow path. Specifically, as... Figure 21 As shown, the sides (e.g., inlet sides) above the first power contacts 324a and 324b of the module housing 354 (and connector module 320) are recessed to define a separator 329 together with the initial segments of the first and second branch portions of the flow path. The separator 329 extends from the outer surface of the module housing 354 (e.g., Figure 21 In the recessed example embodiment, the side above the first power contact 324a and the second power contact 324b of the module housing 354 can also be regarded as an inlet portion defining the flow path, which is downstream of the container inlet 322 and upstream of the first branch portion and the second branch portion of the flow path.

[0103] The pair of longer sides (e.g., vertical sides) of the module housing 354 are also recessed to define subsequent segments of the first and second branch portions of the flow path. In this document, the pair of longer sides of the module housing 354 may be referred to as lateral surfaces in an alternative manner. Figure 21 In China (but in Figure 30 (As shown in the diagram) Sectors of the module housing 354, covered by a printed circuit board (PCB) 362, define a first branch portion and other segments of the second branch portion, as well as a converging portion of the flow path. The other segments of the first and second branch portions respectively include a first curved segment (e.g., a first curved path 330a) and a second curved segment (e.g., a second curved path 330b). As will be discussed in more detail herein, the first and second branch portions converge to form the converging portion of the flow path.

[0104] When the connector module 320 is placed within the receiving cavity in the downstream side of the second housing section 308, the non-recessed side of the module housing 354 abuts against the sidewall of the receiving cavity of the second housing section 308, while the recessed side of the module housing 354, together with the sidewall of the receiving cavity, defines a first branch portion and a second branch portion of the flow path. The connector module 320 can be placed within the receiving cavity of the second housing section 308 via a close-fitting arrangement, such that the connector module 320 is substantially held in place within the nicotine container assembly 300.

[0105] like Figure 22 As shown, connector module 320 includes a core 338 configured to transfer a nicotine vapor pre-mixed substance to heater 336. Heater 336 is configured to heat the nicotine vapor pre-mixed substance during vaporization to generate nicotine vapor. Heater 336 is electrically connected to at least one electrical contact of connector module 320. For example, one end of heater 336 (e.g., a first end) may be connected to a first electrical contact 324a, while the other end of heater 336 (e.g., a second end) may be connected to a second electrical contact 324b. In an example embodiment, heater 336 includes a folded heating element. In this case, core 338 may have a planar form, configured to be held by the folded heating element. When assembling nicotine container assembly 300, core 338 is configured to connect with absorbent material 346 (e.g., ...). Figure 25 Fluid communication allows nicotine vapor pre-formulation in absorbent material 346 (when nicotine container assembly 300 is activated) to be transferred to core 338 via capillary action.

[0106] In an example implementation, the incoming airflow into the nicotine container assembly 300 through container inlet 322 is guided by separator 329 into a first branch and a second branch of the flow path. Separator 329 may be wedge-shaped and configured to split the incoming airflow in opposite directions (e.g., at least initially). The split airflow may include a first airflow (traveling through the first branch of the flow path) and a second airflow (traveling through the second branch of the flow path). After being split by separator 329, the first airflow travels along the inlet side and continues around the corner to a first lateral surface and along the first lateral surface to a first curved path 330a. Similarly, the second airflow travels along the inlet side and continues around the corner to a second lateral surface and along the second lateral surface to a second curved path 330b (e.g., Figure 30 The converging portion of the flow path is downstream of the first and second branch portions. Heater 336 and core 338 are downstream of the converging portion of the flow path. Therefore, in the converging portion of the flow path (e.g., Figure 30In the convergence path 330c, the first airflow combines with the second airflow to exit at the module outlet 368 (e.g., in the module housing 354) through the module housing 354. Figure 28 (marked in the middle) forms a combined flow before heater 336 and core 338.

[0107] Figure 23 yes Figure 22 The image shows an exploded view of the core and heater. (See reference...) Figure 23 The core 338 can be a fiber pad or other structure with pores / voids designed for capillary action. Alternatively, the core 338 can have a rectangular shape, but the example embodiments are not limited thereto. For example, the core 338 can have an alternative shape of an irregular hexagon, with two sides facing inward and angled toward the heater 336. The core 338 can be formed into the desired shape or cut from a larger sheet into such a shape. When the lower section of the core 338 tapers toward the winding section of the heater 336 (e.g., a hexagonal shape), the possibility of nicotine vapor premixing remaining in a portion of the core 338 that continuously avoids evaporation (due to its distance from the heater 336) can be reduced or avoided. Furthermore, as described above, the heater 336 can include a folded heating element configured to hold the core 338. This folded heating element may also include at least one tip 337 configured to protrude into the core 338.

[0108] In an example embodiment, heater 336 is configured to undergo Joule heating (also known as ohmic / resistive heating) when an electric current is applied thereto. More specifically, heater 336 may be formed of one or more conductors (resistive materials) and is configured to generate heat when an electric current passes through it. The current may be supplied from a power source (e.g., a battery) within the device body 100 and transmitted to heater 336 via a first electrical contact 324a or a second electrical contact 324b.

[0109] The conductor (resistive material) suitable for heater 336 includes iron-based alloys (e.g., stainless steel) and / or nickel-based alloys (e.g., nickel-chromium alloys). Heater 336 may be made of a conductive sheet (e.g., metal, alloy) that is stamped to cut a winding pattern therefrom. The winding pattern may have curved segments arranged alternately with horizontal segments, allowing the horizontal segments to zigzag back and forth while extending parallel. 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 the example embodiments are not limited to this. To obtain the form of heater 336 shown in the figures, the winding pattern may be folded to clamp the core 338. Additionally, when the tip 337 is part of heater 336, the protrusions corresponding to the tip 337 are bent (e.g., inward and / or orthogonally) before folding the winding pattern. Due to the tip 337, the likelihood of the core 338 slipping out of heater 336 is reduced or prevented. The heater and related structures are discussed in more detail in U.S. Application No. 15 / 729,909, filed October 11, 2017, entitled “Folded Heater For Electronic Vaping Device,” the entire contents of which are incorporated herein by reference.

[0110] Figure 24 It includes Figure 17 An exploded view of the first shell section of the nicotine container assembly. (Refer to...) Figure 24The first housing section 302 includes a vapor passage 316. The vapor passage 316 is configured to receive nicotine vapor generated by the heater 336 and is in fluid communication with the container outlet 304. In an example embodiment, the dimensions (e.g., diameter) of the vapor passage 316 gradually increase as it extends toward the container outlet 304. Furthermore, the vapor passage 316 may be integrally formed with the first housing section 302. An insert 342 and a seal 344 are disposed at the upstream end of the first housing section 302 to define a reservoir for the nicotine container assembly 300. For example, the insert 342 may be disposed within the first housing section 302 such that the peripheral surface of the insert 342 engages along an edge (e.g., via an interference fit) with the inner surface of the first housing section 302, 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 air-tight). Furthermore, seal 344 is attached to the upstream side of insert 342 to close the reservoir outlet in insert 342, thereby providing a fluid-tight (e.g., liquid-tight and / or air-tight) containment of the nicotine vapor pre-formulated in the reservoir. In this document, the first housing section 302, insert 342, and seal 344 may be collectively referred to as the first section. As will be discussed in more detail herein, the first section is configured to hermetically seal the nicotine vapor pre-formulated until the nicotine container assembly 300 is started.

[0111] In the example implementation, the insert 342 includes a retainer portion protruding from the upstream side (e.g., Figure 24 (as shown) and the connector portion protruding from the downstream side ( Figure 24 (Hidden and not visible). The retainer portion of the insert 342 is configured to accommodate absorbent material 346 (e.g., Figure 25The connector portion of the insert 342 is configured to engage with the steam passage 316 of the first housing section 302. The connector portion of the insert 342 may be configured to be disposed within the steam passage 316 and thus 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 thus engage with the exterior of the steam passage 316. The insert 342 also defines a reservoir outlet through which nicotine vapor premixed streams flow when the seal 344 is punctured during startup of the nicotine container assembly 300. The retainer portion and connector portion of the insert 342 may be located between the reservoir outlets (e.g., the first reservoir outlet and the second reservoir outlet), but the example embodiments are not limited thereto. Furthermore, the insert 342 defines a steam conduit extending through the retainer portion and the connector portion. As a result, when the insert 342 is placed within the first housing section 302, the steam conduit of the insert 342 will be aligned with and in fluid communication with the steam passage 316 to form a continuous path through the reservoir to the container outlet 304 for the nicotine vapor generated by the heater 336 during vapor fumigation.

[0112] A seal 344 is attached to the upstream side of the insert 342 to cover the reservoir outlet in the insert 342. In an example embodiment, the seal 344 defines an opening (e.g., a central opening) configured to provide adequate clearance to accommodate a retainer portion (which protrudes 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 actuating pin 314a and the second actuating pin 314b of the nicotine container assembly 300, the two pierced sections of the seal 344 are pushed into the reservoir as flaps, thus forming two pierced openings in the seal 344 (e.g., one on each side of the central opening). The size and shape of the pierced openings in the seal 344 may correspond to the size and shape of the reservoir outlet in the insert 342. Conversely, when in a position such as Figure 24 In the unpunctured state shown, seal 344 will have a planar form and only one opening (e.g., a central opening). Seal 344 is designed to be robust enough to remain intact during normal movement and / or operation of the nicotine container assembly 300, thereby preventing premature / unintentional breakage. For example, seal 344 may be a coated foil (e.g., aluminum-backed polyethylene terephthalate (PET)).

[0113] Figure 25 It includes Figure 17 A partial exploded view of the second shell section of the nicotine container assembly. See also... Figure 25The second housing section 308 is configured to include various components configured to release, receive, and heat the nicotine vapor pre-formulation. For example, a first actuating pin 314a and a second actuating pin 314b are configured to pierce a reservoir in the first housing section 302 to release the nicotine vapor pre-formulation. Each of the first actuating pin 314a and the second actuating pin 314b has a distal end extending through a corresponding one of the first pin opening 315a and the second pin opening 315b in the second housing section 308. In an example embodiment, the distal ends of the first actuating pin 314a and the second actuating pin 314b are visible after assembly (e.g., Figure 17 The remainder of the first activation pin 314a and the second activation pin 314b are concealed within the nicotine container assembly 300 and are not visible. 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 prior to activation of the nicotine container 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 container assembly 300, the proximal end of each of the first activation pin 314a and the second activation pin 314b will advance through the insert 342, resulting in piercing the seal 344, which will release the nicotine vapor pre-formulated from the reservoir. Movement of the first activation pin 314a can be independent of movement of the second activation pin 314b (and vice versa). The first activation pins 314a and the second activation pins 314b will be discussed in more detail here.

[0114] Absorbent material 346 can be disposed within a retainer (e.g., a cap retainer 345). Absorbent material 346 is also downstream of and in fluid communication with the core 338. Furthermore, as described above, absorbent material 346 is configured to engage with the retainer portion of the insert 342 (e.g., ...). Figure 24 As shown, it protrudes from the upstream side of the insert 342. The absorbent material 346 may have an annular form, but the example embodiment is not limited to this. Figure 25 As depicted, the absorbent material 346 can resemble a hollow cylinder. In this case, the outer diameter of the absorbent material 346 can be substantially equal to (or slightly larger than) the length of the core 338. The inner diameter of the absorbent material 346 can be smaller than the average outer diameter of the retainer portion of the insert 342 to create an interference fit. To facilitate engagement with the absorbent material 346, the tip of the retainer portion of the insert 342 can be tapered. The absorbent material 346 is configured to receive and contain a predetermined amount of nicotine vapor pre-formulated material released from the reservoir upon activation of the nicotine container assembly 300.

[0115] Core 338 is positioned within nicotine container assembly 300 to be in fluid communication with absorbent material 346, allowing nicotine vapor pre-formulation to be drawn from absorbent material 346 to heater 336 via capillary action. Core 338 may be based on Figure 25 The view shown physically contacts the upstream side of the absorbent material 346 (e.g., the bottom of the absorbent material 346). Additionally, the core 338 may be aligned with the diameter of the absorbent material 346, but the example embodiment is not limited to this.

[0116] like Figure 25 (and those preceding) Figure 23 As shown in the diagram, heater 336 may have a folded configuration to clamp the opposing surfaces of core 338 and establish thermal contact with these opposing surfaces. Heater 336 is configured to heat core 338 during vaporization to generate nicotine vapor. To facilitate this heating, a first end of heater 336 may be electrically connected to a first electrical contact 324a, and a second end of heater 336 may be electrically connected to a second electrical contact 324b. As a result, current can be supplied from a power source (e.g., a battery) within the device body 100 and transmitted to heater 336 via the first electrical contact 324a or via the second electrical contact 324b. For brevity, the above has already discussed (e.g., in conjunction with...) Figure 21-22 Other details regarding the connector module 320 will not be repeated in this section. In the example implementation, although in Figure 25 Hidden and not visible, the second housing section 308 includes a receiving cavity for the connector module 320. The second housing section 308 and the aforementioned components located therein are collectively referred to as the second section. During vaporization, nicotine vapor generated by the heater 336 is drawn through the steam conduit of the insert 342, through the steam passage 316 of the first housing section 302, out of the container outlet 304 of the nicotine container assembly 300, and through the steam passage 136 of the mouthpiece 102 to reach the steam outlet.

[0117] Figure 26 yes Figure 25 Exploded view of the center cap retainer. (Refer to...) Figure 26The cap retainer 345 includes a base portion 345a and a cylindrical portion 345b. In an example embodiment, the base portion 345a and the cylindrical portion 345b are integrally formed. The cylindrical portion 345b defines an aperture configured to receive absorbent material 346. Optionally, the inner lower surface of the aperture may include a flange (or other protrusion) to support the absorbent material 346, such that the absorbent material 346 does not merely slide across or droop from the cap retainer 345 (e.g., when the absorbent material 346 is saturated with nicotine vapor pre-formulation released from the reservoir). Additionally, the base portion 345a defines a recess configured to receive a washer 345c. Furthermore, a pair of integrally formed pillars may extend from the base portion 345a and along the exterior of the cylindrical portion 345b to protrude beyond the edge of the cylindrical portion 345b. When the top cap retainer 345 is assembled within the nicotine container assembly 300, the two integrally formed pillars can abut the underside of the insert 342, with a portion of the seal 344 located therebetween.

[0118] Figure 27 yes Figure 25 An exploded view of the starter pin. (Refer to...) Figure 27 The activating pin can be in the form of a first activating pin 314a and a second activating pin 314b. While two activating pins are shown and discussed in conjunction with the non-limiting embodiments herein, it should be understood that, alternatively, the nicotine container assembly 300 may include only one activating pin. Figure 27 In this configuration, the first starting pin 314a may include a first blade 348a, a first actuator 350a, and a first O-ring 352a. Similarly, the second starting pin 314b may include a second blade 348b, a second actuator 350b, and a second O-ring 352b.

[0119] In an example embodiment, 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 may be achieved by a snap-fit ​​connection, an interference fit (e.g., a friction fit) connection, an adhesive, or other suitable joining techniques. The tip of each of the first blade 348a and the second blade 348b may have one or more curved or recessed edges that taper upwards to 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, while their arc lengths may be different. The first blade 348a and the second blade 348b may be formed from a sheet of metal (e.g., stainless steel) that is cut or otherwise shaped to have a desired profile and bent into its final form. Alternatively, the first blade 348a and the second blade 348b may be formed from plastic (e.g., when integrally formed with the first actuator 350a and the second actuator 350b).

[0120] Based on the plan view, the dimensions and shapes of the first blade 348a, the second blade 348b, and the portions of the first actuator 350a and the second actuator 350b integrally formed (or mounted) with the first and second blades can correspond to the dimensions and shapes of the reservoir outlet in the insert 342. Furthermore, as... Figure 27 As shown, the first activating pin 314a and the second activating pin 314b may include protruding edges (e.g., curved inner lips facing each other) configured to push the two pierced sections of the seal 344 into the reservoir when the first blade 348a and the second blade 348b are advanced into the reservoir. In a non-limiting embodiment, when the first activating pin 314a and the second activating pin 314b are fully inserted into the nicotine container assembly 300, the two flaps (from the two pierced sections of the seal 344) may be located between the curved sidewall of the reservoir outlet of the insert 342 and the corresponding curved portions of the protruding edges of the first activating pin 314a and the second activating pin 314b. As a result, the possibility of the two pierced openings in the seal 344 being blocked (by the two flaps from the two pierced sections) can be reduced or prevented. Furthermore, the first ignition pin 314a and the second ignition pin 314b can be configured to guide the nicotine vapor premix from the reservoir toward the absorbent material 346 within the top cap retainer 345.

[0121] The lower portion (e.g., the distal portion) of each of the first actuator 350a and the second actuator 350b is configured to extend through the bottom section (e.g., the upstream end) of the second housing section 308. The 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 disposed in an annular groove 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 with the inner surfaces of the shafts of the first actuator 350a and the second actuator 350b and the corresponding openings in the second housing section 308 to provide a fluid seal. Therefore, when the first actuation pin 314a and the second actuation pin 314b are pushed inward to actuate the nicotine container assembly 300, the first O-ring 352a and the second O-ring 352b can move together with the corresponding 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. This helps to reduce or prevent leakage of nicotine vapor pre-mixed material through the openings in the second housing section 308 for the first actuation pin 314a and the second actuation pin 314b. The first O-ring 352a and the second O-ring 352b can be formed of silicone.

[0122] The perforator for the nicotine container assembly 300 may include a notch configured to engage with a clamp to prevent premature actuation of the perforator. For example, the shafts of the first actuating pin 314a and the second actuating pin 314b may define a first notch 351a and a second notch 351b, respectively, configured to engage with such a clamp. In an example embodiment, the clamp may be a planar structure defining a first groove and a second groove configured to engage with the first notch 351a and the second notch 351b, respectively. When the clamp engages with the shafts of the first actuating pin 314a and the second actuating pin 314b (via the first notch 351a and the second notch 351b, respectively), it may be adjacent to the second housing section 308, thereby preventing the first actuating pin 314a and / or the second actuating pin 314b from being accidentally pushed into the nicotine container assembly 300. As a result, the first activating pin 314a and the second activating pin 314b can be sufficiently limited (e.g., during transport and / or operation) to reduce or prevent the possibility of premature actuation. The clamp can be removed at the appropriate time when the nicotine container assembly 300 is activated (e.g., by an adult vaporizer).

[0123] Figure 28 yes Figure 22 A perspective view of the connector module without a core and heater. Figure 29 yes Figure 28 An exploded view of the connector module. Figure 30 yes Figure 28Another exploded view of the connector module. (Refer to...) Figures 28-30 The module housing 354 forms the frame of the connector module 320. The module housing 354 specifically defines the flow path of the separator 329 and the air drawn into the nicotine container assembly 300. When assembled within the nicotine container assembly 300, the downstream edge of the module housing 354 can engage with the upstream edge of the base portion 345a of the cap retainer 345 (e.g., Figure 26 As a result, heater 336 and core 338 (e.g., Figure 22 The module housing 354 and the top cap retainer 345 can be closed (at least partially). Additionally, the internal space defined by the module housing 354 and the top cap retainer 345 can be considered a heating chamber during assembly (where the heater 336 and core 338 are disposed). The heating chamber is in fluid communication with a flow path upstream of the module housing 354 via the module outlet 368.

[0124] As described above, the flow path of air drawn into the nicotine container assembly 300 includes a first branch portion, a second branch portion, and a converging portion defined by the module housing 354. In the example embodiment, the first and second branch portions are symmetrical portions bisected by the axis of the converging portion corresponding to the flow path. For example, as Figure 30 As shown, the first branch portion, the second branch portion, and the converging portion may respectively include a first curved path 330a, a second curved path 330b, and a converging path 330c. The first curved path 330a and the second curved path 330b may be substantially U-shaped paths, while the converging path 330c may be substantially linear paths. Based on an axis corresponding to the converging path 330c and aligned with the top of the separator 329, the first branch portion of the flow path may be a mirror image of the second branch portion of the flow path. During vapor fumigation, the air drawn in through the container inlet 322 may be separated by the separator 329 and initially flow away from the separator 329 in opposite directions, then flow in parallel, and then each airflow makes a U-turn (via the first curved path 330a and the second curved path 330b) and converges into a combined flow (via the converging path 330c), which returns towards the separator 329 before reaching the heating chamber through the module outlet 368. Heater 336 and core 338 can be positioned such that both sides are exposed to the airflow passing through module outlet 368 substantially equally. During vaporization, the generated nicotine vapor is entrained by the airflow traveling through the heating chamber to vapor passage 316.

[0125] A baffle 370 may be disposed within the module outlet 368 to separate the airflow entering the heating chamber. Heater 336 and core 338 (e.g., Figure 22Downstream of module outlet 368, and can be oriented to align with septum 370. Due to septum 370, the airflow can be separated relatively equally, such that a first flow passes along a first side (and core 338) of heater 336, while a second flow passes along a second side (and core 338) of heater 336. In an example embodiment, the magnitudes of the first and second flows (e.g., velocity, volumetric flow rate, mass flow rate) can be within ±10% of each other. For example, regarding the air drawn into the heating chamber, 51% can be part of the first flow, and 49% can be part of the second flow, but it should be understood that variations within the aforementioned range are possible. In addition to reducing flow imbalance through the heating chamber, septum 370 can also be considered a rectifier.

[0126] The septum 370 may be in the form of a rod that extends across (e.g., bisects) the module outlet 368. Regarding dimensions, the septum 370 may have a thickness of approximately 150–250 micrometers (e.g., 200 micrometers). The thickness of the septum 370 coincides with the area of ​​the module outlet 368 blocked by the septum 370. Therefore, the thickness of the septum 370 and / or the dimensions of the module outlet 368 can be adjusted to provide the desired draw resistance (e.g., 25 mm water column) to the nicotine e-vapor device 500. Additionally, the width of the septum 370 may be between 525–875 micrometers (e.g., 700 micrometers). This width allows the septum 370 to extend 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 septum 370 may correspond to the diameter of the module outlet 368. Alternatively, in the case where the module outlet 368 has an elliptical cross-section, the length of the septum 370 may correspond to the axis of the module outlet 368 (e.g., minor axis, major axis).

[0127] like Figures 29-30 As shown, 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 orthogonally oriented relative to the contact surface (which may be square), but the example embodiment is not limited thereto. The module housing 354 may define a pair of shallow recesses and a pair of orifices to facilitate the 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 positioned in a corresponding one of the pair of shallow recesses so as to be substantially flush with the outer surface of the module housing 354 (e.g., Figure 21 Additionally, the contact leg of each of the first power contact 324a and the second power contact 324b may extend through a corresponding one of a pair of orifices to protrude from the downstream side of the module housing 354 (e.g., Figure 28The heater 336 can then be connected to the contact legs of each of the first power contact 324a and the second power contact 324b.

[0128] Printed circuit board (PCB) 362 on its upstream side (e.g., Figure 30 This includes multiple data contacts 326, and on its downstream side (e.g., Figure 29 The module includes multiple electronic components, including sensor 364. Sensor 364 can be positioned on a printed circuit board (PCB) 362 such that sensor 364 is within a convergence path 330c defined by module housing 354. In an example embodiment, the printed circuit board (PCB) 362 (and associated components fixed thereon) is a separate structure that is initially inserted into a receiving cavity in the downstream side of the second housing segment 308 such that data contact 326 is exposed by data contact opening 327 of the second housing segment 308. Subsequently, module housing 354 (having a first power contact 324a, a second power contact 324b, a heater 336, and a core 338 mounted thereon) can 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 segment 308, respectively. Alternatively, in order to simplify the above two-step insertion process into a one-step insertion process, it should be understood that the printed circuit board (PCB) 362 (and related components fixed thereon) may be attached to the module housing 354 (e.g., to form a single integrated structure) to cover the first bending path 330a, the second bending path 330b, the convergence path 330c and the module outlet 368.

[0129] As described above, the module outlet 368 can be a suction resistance (RTD) port. In this configuration, the suction 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 container inlet 322). In an example embodiment, the size of the module outlet 368 can be selected such that the suction resistance is between 20 and 100 mm water column (e.g., between 25 and 50 mm water column). For example, a module outlet 368 with a diameter of 1.0 mm can produce a suction resistance of 88.3 mm water column. In another case, a module outlet 368 with a diameter of 1.1 mm can produce a suction resistance of 73.6 mm water column. In another case, a module outlet 368 with a diameter of 1.2 mm can produce a suction resistance of 58.7 mm water column. In yet another case, a module outlet 368 with a diameter of 1.3 mm can produce a suction resistance of approximately 40-43 mm water column. In particular, due to the internal arrangement of the module outlet 368, its size can be adjusted without affecting the external aesthetics of the nicotine container assembly 300, thereby allowing for a more standardized product design of nicotine container assemblies with various suction resistances (RTDs), while also reducing the possibility of unintentionally blocking air ingress.

[0130] Although many exemplary embodiments have been disclosed herein, it should be understood that other variations are possible. Such variations should not be considered as departing from the spirit and scope of this disclosure, and as will be apparent to those skilled in the art, all such modifications are intended to be included within the scope of the appended claims.
