[0041] This document discloses some detailed exemplary embodiments. However, the specific structural and functional details disclosed herein are merely representative and for the purpose of describing exemplary embodiments. Exemplary embodiments may be implemented in many alternative forms and should not be considered limited to the exemplary embodiments listed herein.

[0042] Therefore, while exemplary embodiments can have various modifications and alternative forms, exemplary embodiments thereof are shown by way of example in the accompanying drawings and will be described in detail herein. However, it should be understood that there is no intention to limit exemplary embodiments to the specific forms disclosed; rather, exemplary embodiments cover all modifications, equivalents, and alternative forms thereof. Throughout the description of the accompanying drawings, the same reference numerals denote the same elements.

[0043] It should be understood that when an element or layer is referred to as "on another element or layer," "connected to another element or layer," "coupled to another element or layer," "attached to another element or layer," "adjacent to another element or layer," "covering another element or layer," etc., the element or layer may be directly located on, connected to, coupled to, attached to, adjacent to, or cover the other element or layer, or there may be intermediate elements or layers. Conversely, when an element is referred to as "directly located on another element or layer," "directly connected to another element or layer," "directly coupled to another element or layer," etc., there are no intermediate elements or layers. Throughout the specification, the same reference numerals denote the same elements. As used herein, the term "and / or" includes one or more of the listed related items, any and all combinations or sub-combinations.

[0044] It should be understood that although the terms first, second, third, etc., used herein may describe different elements, regions, layers, and / or portions, these elements, regions, layers, and / or portions should not be limited by these terms. These terms are used only to distinguish one element, region, layer, or portion from another. Therefore, the first element, region, layer, or portion discussed below may be referred to as the second element, region, layer, or portion without departing from the teachings of the exemplary embodiments.

[0045] For ease of description, spatially related terms (e.g., "below," "below," "lower," "above," "upper," etc.) may be used to describe the relationship between one element or feature shown in the accompanying drawings and another element or feature. It should be understood that, in addition to the orientation depicted in the accompanying drawings, spatially related terms are intended to include different orientations of the device in use or operation. For example, if the device in the accompanying drawings is flipped, an element described as "below" or "below other elements or features" would 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 spatially related descriptive terms used herein shall be interpreted accordingly.

[0046] The terminology used herein is for the purpose of describing different exemplary embodiments only and is not intended to limit the exemplary embodiments. The singular forms “a,” “an,” and “described” as used herein are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should be further understood that, when used in this specification, the terms “includes,” “including,” “comprises,” and / or “comprising” indicate 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.

[0047] When the terms “same” or “identical” are used in the description of exemplary embodiments, it should be understood that some imprecision may exist. Therefore, when an element or value is referred to as being the same as another element or value, it should be understood that the element or value is the same as another element or value within a manufacturing or operational tolerance range (e.g., ±10%).

[0048] When the terms “approximately” or “substantially” are used with respect to numerical values, it should be understood that the relevant numerical value includes manufacturing or operational tolerances (e.g., ±10%) around the value. Furthermore, when the terms “generally” and “substantially” are used with respect to geometry, it should be understood that a precise geometry is not required, but rather the boundaries of the shape are within the scope of this disclosure.

[0049] 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 exemplary embodiments pertain. It should be further understood that, unless expressly defined herein, terms (including those defined in commonly used dictionaries) shall be interpreted as having a meaning consistent with their meaning in the context of the relevant technical field and shall not be interpreted in an idealized or overly formal sense.

[0050] The hardware may be implemented using processing or control circuitry, 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 device or multiple devices capable of responding to and executing instructions in a defined manner.

[0051] Figure 1This is a front view of a non-nicotine electronic cigarette device according to an exemplary embodiment. Figure 2 yes Figure 1 Side view of a non-nicotine electronic cigarette device. Figure 3 yes Figure 1 Rear view of a non-nicotine electronic cigarette device. See also Figures 1 to 3 The non-nicotine electronic cigarette device 500 includes: a device body 100 configured to receive a non-nicotine pod assembly 300. The non-nicotine pod assembly 300 is a modular article configured to hold a non-nicotine vapor precursor formulation. The non-nicotine vapor precursor formulation is a material or combination of materials that does not contain nicotine and can be converted into non-nicotine vapor. For example, the non-nicotine vapor precursor formulation may include liquid, solid, and / or gel formulations. These may include (e.g., but not limited to): solutions and suspensions (e.g., emulsions) containing water, oils, beads, solvents, active ingredients, ethanol, plant extracts, non-nicotine compounds, natural or artificial flavorings, vapor-forming agents such as glycerin and propylene glycol, and / or any other ingredients suitable for inhalation. During inhalation, the non-nicotine electronic cigarette device 500 is configured to: heat the non-nicotine vapor precursor formulation to generate non-nicotine vapor. Non-nicotine vapor, non-nicotine aerosol and non-nicotine dispersant are used interchangeably and refer to substances generated or output by the disclosed, claimed equipment and / or its equivalents, wherein such substances do not contain nicotine.

[0052] like Figure 1 and Figure 3 As shown, the non-nicotine electronic cigarette device 500 extends in the longitudinal direction and has a length greater than its width. Furthermore, as... Figure 2 As shown, the length of the non-nicotine electronic cigarette device 500 is greater than its thickness. Furthermore, the width of the non-nicotine electronic cigarette device 500 may be greater than its thickness. Assuming an xyz Cartesian coordinate system, the length of the non-nicotine electronic cigarette 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 non-nicotine electronic cigarette device 500 may have a substantially linear form with tapered ends, but the exemplary embodiment is not limited to this.

[0053] 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, electronic, and / or circuitry associated with the operation of the non-nicotine electronic cigarette device 500. For example, the device housing of the device body 100 may enclose a power source configured to supply power to the non-nicotine electronic cigarette device 500, which may include supplying current to the non-nicotine pod assembly 300. Furthermore, 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 constituent parts 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.

[0054] 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 may also have other shapes depending on the shape of the frame structure 112. The frame structure 112 defines a through-hole 150 configured to receive a non-nicotine pod assembly 300. This document incorporates, for example… Figure 9 Let's discuss the through-hole 150 in more detail.

[0055] The front cover 104 also defines a secondary opening configured to receive a light guide arrangement. The secondary opening may resemble a slot (e.g., a segmented slot), but may also have other shapes depending on the shape of the light guide arrangement. In an exemplary embodiment, the light guide arrangement 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 also possible depending on the shape of the button. The first button housing 122 is configured to expose the first button lens 124, while the second button housing 123 is configured to expose the second button lens 126.

[0056] The operation of the non-nicotine electronic cigarette device 500 can be controlled by a first button 118 and a second button 120. For example, the first button 118 can be a power button, and the second button 120 can 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.

[0057] Frame 106 (e.g., base frame) is the central support structure for the device body 100 (and the non-nicotine electronic cigarette device 500 as a whole). Frame 106 may be referred to as a rack. 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”) is associated with an adult smoker during inhalation, while “downstream” (and, conversely, “upstream”) is associated with the flow of non-nicotine vapor. Bridging sections may be provided between the opposing inner surfaces of the side sections (e.g., approximately at the midpoint of the length of frame 106) for additional strength and stability. Frame 106 may be integrally formed as a single structure.

[0058] Regarding the materials used in its construction, frame 106 can be formed from an alloy or a 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 (e.g., to provide a superior appearance), frame 106 can be provided with a surface finish. In an exemplary embodiment, frame 106 (e.g., when formed from an aluminum alloy) can be anodized. In another embodiment, frame 106 (e.g., when formed from a zinc alloy) can be coated with hard enamel or paint. In another embodiment, frame 106 (e.g., when formed from polycarbonate) can be metallized. In yet another embodiment, frame 106 (e.g., when formed from acrylonitrile-butadiene-styrene) can be electroplated. It should be understood that the construction materials of frame 106 can also be applied to front cover 104, rear cover 108 and / or other suitable parts of non-nicotine electronic cigarette device 500.

[0059] 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 may also have other shapes depending on the shape of the frame structure 112. In an exemplary 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, in addition to (or instead of) the light guide arrangement and buttons on the front of the non-nicotine electronic cigarette device 500, a light guide arrangement and / or buttons may also be provided on the rear of the non-nicotine electronic cigarette device 500.

[0060] 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 clips configured to interlock with corresponding mating members of the frame 106. In a non-limiting embodiment, the clips may be in the form of lugs with orifices configured to receive corresponding mating members of the frame 106 (e.g., protrusions with beveled edges). Alternatively, the front cover 104 and / or rear cover 108 can be configured to engage with the frame 106 via 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 via other suitable arrangements and techniques.

[0061] The main body 100 also includes a mouthpiece 102. The mouthpiece 102 can be fixed to the proximal end of the frame 106. Furthermore, as... Figure 2 As shown, in an exemplary embodiment where the frame 106 is sandwiched between the front cover 104 and the rear cover 108, the mouthpiece 102 may abut the front cover 104, the frame 106, and the rear cover 108. Furthermore, in a non-limiting embodiment, the mouthpiece 102 may be engaged with the device housing via a bayonet connection.

[0062] Figure 4 yes Figure 1 A close-up view of a non-nicotine electronic cigarette device. See also 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 integrally formed parts of the mouthpiece 102. Although the outlet surface is shown defining four steam outlets, it should be understood that the exemplary embodiments are 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.

[0063] Figure 5 yes Figure 1 A remote view of a non-nicotine electronic cigarette device. See also Figure 5The remote end of the non-nicotine electronic cigarette device 500 includes a port 110. Port 110 is configured (e.g., via a USB / mini-USB cable) to receive current from an external power source to charge the internal power supply within the non-nicotine electronic cigarette device 500. Furthermore, port 110 can also be configured (e.g., via a USB / mini-USB cable) to send data to and / or receive data from another non-nicotine electronic cigarette device or other electronic device (e.g., a telephone, tablet, computer). Additionally, the non-nicotine electronic cigarette device 500 can be configured to wirelessly communicate with the electronic device, such as a telephone, via an application software (app) installed on it. In this case, an adult smoker can control or otherwise interact with the non-nicotine electronic cigarette device 500 via the app (e.g., locate the non-nicotine electronic cigarette device, check usage information, change operating parameters).

[0064] Figure 6 yes Figure 1 A perspective view of a non-nicotine electronic cigarette device. Figure 7 yes Figure 6 A magnified view of the pod entrance. See also... Figures 6 to 7 As described above, the non-nicotine electronic cigarette device 500 includes a non-nicotine pod assembly 300 configured to hold a non-nicotine vapor precursor formulation. The non-nicotine pod assembly 300 has an upstream end (arranged facing a light guide) and a downstream end (facing a mouthpiece 102). In a non-limiting embodiment, the upstream end is the surface of the non-nicotine pod assembly 300 opposite to the downstream end. The upstream end of the non-nicotine pod assembly 300 defines a pod inlet 322. The device body 100 defines a through-hole (e.g., Figure 9 A through-hole 150 is configured to receive a non-nicotine pod assembly 300. In an exemplary embodiment, a 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 that the pod inlet 322 is exposed when the non-nicotine pod assembly 300 is located in the through hole of the device body 100.

[0065] For example, instead of following the contour of the front cover 104 (so as to be flush with the front of the non-nicotine pod assembly 300, thereby obscuring the pod inlet 322), the upstream edge of the frame structure 112 is scooped, configured to guide ambient air into the pod inlet 322. This angled / scooped configuration (e.g., it may be curved) can help reduce or prevent clogging of the air intake (e.g., pod inlet 322) of the non-nicotine e-cigarette device 500. The depth of the scoop can allow less than half (e.g., less than a quarter) of the upstream end face of the non-nicotine pod assembly 300 to be exposed. Furthermore, in a non-limiting embodiment, the pod inlet 322 is in the form of a slot. Additionally, if the device body 100 is considered to extend in a first direction, then the slot can be considered to extend in a second direction, wherein the second direction is transverse to the first direction.

[0066] Figure 8 yes Figure 6 A cross-sectional view of a non-nicotine electronic cigarette device. Figure 8 The cross-section is taken along the longitudinal axis of the non-nicotine electronic cigarette device 500. As shown, the device body 100 and the non-nicotine pod assembly 300 include mechanical, electronic, and / or circuitry associated with the operation of the non-nicotine electronic cigarette device 500, which are discussed in more detail herein and / or incorporated herein by reference. For example, the non-nicotine pod assembly 300 may include mechanical components configured to actuate to release a non-nicotine vapor precursor formulation from an internal sealed reservoir. The non-nicotine pod assembly 300 may also have mechanical aspects configured to engage with the device body 100 to facilitate insertion and seating of the non-nicotine pod assembly 300.

[0067] Furthermore, the non-nicotine pod component 300 can be a "smart pod" comprising electronic components and / or circuitry configured to: store information, receive information from the device body 100, and / or send information to the device body 100. Such information can be used to verify whether the non-nicotine pod component 300 is used with the device body 100 (e.g., to prevent the use of unapproved / counterfeit non-nicotine pod components). Additionally, the information can be used to identify the type of the non-nicotine pod component 300, which is then associated with an e-cigarette profile based on the identified type. The e-cigarette profile can be designed to provide general parameters for heating non-nicotine vapor precursor formulations and can be tuned, refined, or otherwise adjusted by the adult smoker before and / or during vaping.

[0068] The non-nicotine pod assembly 300 can also communicate with the device body 100 regarding other information that may be relevant to the operation of the non-nicotine e-cigarette device 500. Examples of such information may include: the level of the non-nicotine vapor precursor formulation within the non-nicotine pod assembly 300, and / or the length of time that has elapsed since the non-nicotine pod assembly 300 was inserted into the device body 100 and activated. For example, if the non-nicotine pod assembly 300 was inserted into the device body 100 and previously activated some time ago (e.g., 6 months ago), the non-nicotine e-cigarette device 500 may not allow vaping, and an adult smoker may be prompted to replace the non-nicotine pod assembly even if the non-nicotine pod assembly 300 still contains a sufficient level of the non-nicotine vapor precursor formulation.

[0069] The device body 100 may include mechanical components (e.g., complementary structures) configured to engage, retain, and / or activate the non-nicotine pod 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 is further configured to power the non-nicotine pod assembly 300 during inhalation. Additionally, the device body 100 may include electronic components and / or circuitry configured to communicate with the non-nicotine pod assembly 300, different non-nicotine e-cigarette devices, other electronic devices (e.g., telephones, tablets, computers), and / or the adult smoker. The communicated information may include pod-specific data, current inhalation details, and / or past inhalation patterns / history. Such communication may be communicated to the adult smoker via feedback, such as tactile (e.g., vibration), auditory (e.g., beeping sounds), and / or visual (e.g., colored / flashing lights). Port 110 can be used for charging and / or information communication (e.g., via a USB / mini-USB cable).

[0070] Figure 9 yes Figure 6 A perspective view of the main body of a non-nicotine electronic cigarette device. See also 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 non-nicotine pod assembly 300. To facilitate insertion and seating of the non-nicotine pod 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 exemplary embodiment, the first upstream protrusion 128a and the second upstream protrusion 128b are integrally formed with the frame structure 112 and located at two rounded corners of the upstream edge.

[0071] 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. Furthermore, the distal end of the mouthpiece 102 extends through the third downstream opening of the frame structure 112 and enters the through hole 150, so as to be located between the first downstream protrusion 130a and the second downstream protrusion 130b.

[0072] Figure 10 yes Figure 9 A front view of the main body of the device. See also 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 non-nicotine pod assembly 300 seated within the through-hole 150. As a result, during suction, power can be supplied from the device body 100 to the non-nicotine pod assembly 300 via the device electrical connector 132. Furthermore, data can be sent to and / or received from the device body 100 and the non-nicotine pod assembly 300 via the device electrical connector 132.

[0073] Figure 11 yes Figure 10 Enlarged perspective view of the through-hole. See also Figure 11 The distal ends of the first upstream protrusion 128a, the second upstream protrusion 128b, the first downstream protrusion 130a, the second downstream protrusion 130b, and the mouthpiece 102 protrude into the through hole 150. In an exemplary 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 pullable structures (e.g., telescopic members). For example, the first downstream protrusion 130a and the second downstream protrusion 130b may be configured (e.g., spring-loaded) to be in an extended state by default and also configured to temporarily transition to a retracted state (and reversibly return to an extended state) to facilitate insertion of the non-nicotine pod assembly 300.

[0074] Specifically, when the non-nicotine pod assembly 300 is inserted into the through-hole 150 of the device body 100, the groove at the upstream end face of the non-nicotine pod assembly 300 initially engages with the first upstream protrusion 128a and the second upstream protrusion 128b. Then, the non-nicotine pod assembly 300 is pivoted (around the first upstream protrusion 128a and the second upstream protrusion 128b) until the groove at the downstream end face of the non-nicotine pod assembly 300 engages with the first downstream protrusion 130a and the second downstream protrusion 130b. In this case, the axis of rotation of the non-nicotine pod assembly 300 (during pivoting) can be orthogonal to the longitudinal axis of the device body 100. Furthermore, when the non-nicotine pod assembly 300 is pivoted into the through-hole 150 and elastically extended to engage with the groove at the downstream end face of the non-nicotine pod assembly 300, the first downstream protrusion 130a and the second downstream protrusion 130b (which can be biased for traction) can retract. Furthermore, the engagement of the first downstream protrusion 130a and the second downstream protrusion 130b with the groove at the downstream end face of the non-nicotine pod assembly 300 can generate tactile and / or auditory feedback (e.g., an audible click) to notify an adult smoker that the non-nicotine pod assembly 300 is correctly seated in the through-hole 150 of the device body 100.

[0075] Figure 12 yes Figure 10 An enlarged perspective view of the device's electrical contacts. When the non-nicotine capsule assembly 300 is seated within the through-hole 150 of the device body 100, the device's electrical contacts of the device body 100 are configured to engage with the capsule electrical contacts of the non-nicotine capsule assembly 300. See also Figure 12 The 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 non-nicotine capsule assembly 300. As shown, the power contacts of the device electrical connector 132 include a first power contact and a second power contact (which is 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, during assembly, a protrusion extending into the through-hole 150. 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, during assembly, a protrusion extending into the through-hole 150. The first and second power contacts of the device electrical connector 132 can be pulled and biased so that they 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.

[0076] The data contacts of the device electrical connector 132 are configured to transmit data between the non-nicotine pod 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 a different structure that extends into the through-hole 150 during assembly. The data contacts of the device electrical connector 132 can also be pull-mounted and biased (e.g., via a serpentine structure and / or with a spring) so that they 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. For example, when the non-nicotine pod assembly 300 is inserted into the through-hole 150 of the device body 100, the pod electrical contacts of the non-nicotine pod 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 flexible arrangement, they will continue to push the corresponding capsule electrical contacts, thereby helping to ensure proper electrical connection between the device body 100 and the non-nicotine capsule assembly 300. Furthermore, this connection can also be mechanically fixed and have minimal contact resistance to allow power and / or signals to be reliably and accurately transmitted and / or communicated between the device body 100 and the non-nicotine capsule 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 exemplary embodiments are not limited thereto and other configurations may be utilized.

[0077] Figure 13 It involves Figure 12 A partial exploded view of the cigarette holder. See also... Figure 13 The mouthpiece 102 is configured to engage with the device housing via a retaining structure 140. In an exemplary embodiment, the retaining structure 140 is primarily located between the frame 106 and the edge structure 112. As shown, the retaining structure 140 is disposed within the device housing such that the proximal end of the retaining structure 140 extends through the proximal end of the frame 106. The retaining structure 140 may extend slightly beyond the proximal end of the frame 106, or substantially beyond 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 a recessed end, while the distal end of the mouthpiece may be a protruding end.

[0078] For example, the mouthpiece 102 can be coupled (e.g., reversibly coupled) to the retaining structure 140 using a bayonet connection. In this case, the recessed end of the retaining structure 140 can define a pair of opposing L-shaped grooves, while the protruding 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 peripheral portion. Optionally, the end of the peripheral portion can have a serif portion to help reduce or prevent the possibility of unintentional disengagement of the radial members 134 of the mouthpiece 102. In a non-limiting embodiment, the longitudinal portion of the L-shaped groove is parallel to and extends along the longitudinal axis of the device body 100, while the peripheral portion of the L-shaped groove extends around the longitudinal axis (e.g., the central axis) of the device body 100. As a result, in order to couple the mouthpiece 102 to the device housing, Figure 13 The mouthpiece 102 shown is initially rotated 90 degrees to align the radial member 134, which has an inlet, with the longitudinal portion of the L-shaped groove of the retention structure 140. The mouthpiece 102 is then pushed into the retention structure 140 such that the radial member 134 slides along the longitudinal portion of the L-shaped groove until it reaches engagement with each peripheral portion. At this point, the mouthpiece 102 is then rotated such that the radial member 134 travels across the peripheral portions until it reaches the end of each peripheral portion. Where a serif portion is present at each end, tactile and / or auditory feedback (e.g., an audible click) can be generated to notify an adult smoker that the mouthpiece 102 has been properly coupled to the device housing.

[0079] Mouthpiece 102 defines a vapor passage 136 through which non-nicotine vapor flows during inhalation. Vapor passage 136 is in fluid communication with a through-hole 150 (the location where the non-nicotine pod assembly 300 sits within the device body 100). The proximal end of vapor passage 136 may include a flared portion. Furthermore, mouthpiece 102 may include an end cap 138. End cap 138 may taper from its distal end to its proximal end. The outlet surface 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 embodiments are not limited thereto.

[0080] Figure 14 It involves 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. See also Figures 14 to 15The 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 retention structure 140, respectively. The third downstream opening 148c of the frame structure 112 is configured to receive the distal end of the mouthpiece 102.

[0081] like Figure 14 As shown, the first downstream protrusion 130a and the second downstream protrusion 130b are located on the concave side of the retaining structure 140. Figure 15 As shown, the first post 142a and the second post 142b are located on opposite convex sides of the retaining structure 140. A first spring 144a and a 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.

[0082] 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. Furthermore, 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 are located between the frame 106 and the retaining structure 140.

[0083] When the non-nicotine pod assembly 300 is inserted into the through-hole 150 of the device body 100, the downstream end of the non-nicotine pod assembly 300 will press against the first downstream protrusion 130a and the second downstream protrusion 130b of the retention structure 140. As a result, the first downstream protrusion 130a and the second downstream protrusion 130b of the retention structure 140 will elastically yield and retract from the through-hole 150 of the device body 100 (by compressing the first spring 144a and the second spring 144b), thereby allowing the non-nicotine pod assembly 300 to continue to be inserted. In an exemplary embodiment, when the first downstream protrusion 130a and the second downstream protrusion 130b are fully retracted from the through-hole 150 of the device body 100, the displacement of the retention structure 140 may cause the ends of the first post 142a and the second post 142b to contact the inner end faces of the frame 106. Furthermore, since the mouthpiece 102 is coupled to the retention 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., the visible portion, which includes the end cap 138) to also move a corresponding distance away from the device housing.

[0084] Once the non-nicotine pod assembly 300 is fully inserted such that the first and second downstream recesses of the non-nicotine pod assembly 300 reach positions that allow engagement with the first downstream protrusion 130a and the second downstream protrusion 130b, respectively, the energy stored from compressing the first spring 144a and the second spring 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 non-nicotine pod assembly 300, respectively. Furthermore, this engagement can generate tactile and / or auditory feedback (e.g., an audible click) to notify the adult smoker that the non-nicotine pod assembly 300 is correctly seated within the through-hole 150 of the device body 100.

[0085] Figure 16 It involves Figure 14 Exploded views of the front cover, frame, and rear cover. See also... Figure 16 Various mechanical, electronic, and / or circuitry associated with the operation of the non-nicotine electronic cigarette 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 exemplary embodiment, the front cover 104 and rear cover 108 include clips configured to interlock with corresponding mating members of the frame 106. The clips may be in the form of lugs with openings configured to receive corresponding mating members of the frame 106 (e.g., protrusions with beveled edges). Figure 16In the design, the front cover 104 has two rows of four clips per row (eight clips in total for the front cover 104). Similarly, the rear cover 108 has two rows of four clips per row (eight clips in total for the rear cover 108). Corresponding mating members of the frame 106 can be located on the inner sidewall of the frame 106. As a result, when the front cover 104 and the rear cover 108 are engaged, the engaging clips and mating members can be concealed from view. 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 coupled via other suitable arrangements and techniques.

[0086] Figure 17 yes Figure 6 A perspective view of the non-nicotine pod component of a non-nicotine electronic cigarette device. Figure 18 yes Figure 17 Another perspective view of the non-nicotine pod components. Figure 19 yes Figure 18 Another perspective view of the non-nicotine pod components. See also Figures 17 to 19 A non-nicotine pod assembly 300 for a non-nicotine electronic cigarette device 500 includes a pod body configured to hold a non-nicotine vapor precursor formulation. The pod body has an upstream end and a downstream end. The upstream end of the pod body defines a pod inlet 322. The downstream end of the pod body defines a pod outlet 304 in fluid communication with the pod inlet 322 at the upstream end. During inhalation, air enters the non-nicotine pod assembly 300 via the pod inlet 322, and non-nicotine vapor exits the non-nicotine pod assembly 300 via the pod outlet 304. The pod inlet 322 is shown in the figures as a slot. However, it should be understood that the exemplary embodiment is not limited thereto, and other forms are possible.

[0087] The non-nicotine pod assembly 300 includes: a connector module 320 (e.g., Figure 21 The connector module 320 is disposed within the pod body and exposed through an opening in its upstream end. The outer surface of the connector module 320 includes at least one electrical contact. The at least one electrical contact may include 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 non-nicotine pod assembly 300 is configured to connect with the first power contact of the device electrical connector 132 of the device body 100 (e.g., ...). Figure 12 The power contact 324b of the non-nicotine pod assembly 300 is electrically connected to the power contact 324b of the device electrical connector 132 of the device body 100 (e.g., adjacent to the first upstream protrusion 128a). Similarly, the second power contact 324b of the non-nicotine pod 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 first upstream protrusion 128a). Figure 12The power contact adjacent to the second upstream protrusion 128b is electrically connected. Furthermore, at least one electrical contact of the non-nicotine pod assembly 300 includes a plurality of data contacts 326. The plurality of data contacts 326 of the non-nicotine pod assembly 300 are configured to connect with the data contacts of the device electrical connector 132 (e.g., ...). Figure 12 The five protrusions in the middle are electrical connections. Although two power contacts and five data contacts are shown in relation to the non-nicotine pod assembly 300, it should be understood that other variations may exist depending on the design of the device body 100.

[0088] In an exemplary embodiment, the non-nicotine pod assembly 300 includes a front surface, a rear surface opposite the front surface, a first side surface between the front and rear surfaces, a second side surface opposite the first side surface, an upstream end face, and a downstream end face opposite the upstream end face. The angles of the side surfaces and end faces (e.g., the angle between the first side surface and the upstream end face, the angle between the upstream end face and the second side surface, the angle between the second side surface and the downstream end face, and the angle between the downstream end face and the first side surface) may be rounded. However, in some cases, these angles may be angled. Furthermore, the outer peripheral edge of the front surface may be in the form of a boss. The outer surface of the connector module 320 (exposed by the pod body) can be considered as part of the upstream end face of the non-nicotine pod assembly 300. The front surface of the non-nicotine pod assembly 300 may be wider and longer than the rear surface. In this case, the first and second side surfaces may be angled inwards towards each other. The upstream and downstream end faces may also be angled inwards towards each other. Because of the angled surfaces, insertion of the non-nicotine pod 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 non-nicotine pod assembly 300 being incorrectly inserted into the device body 100 can be reduced or prevented.

[0089] As shown in the figure, the pod body of the non-nicotine pod 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 pod outlet 304. Optionally, the edge of the pod outlet 304 may be a recessed or serrated region. In this case, the region may resemble a recess, wherein the side of the edge adjacent to the rear of the non-nicotine pod assembly 300 may be open, while the side of the edge adjacent to the front may be surrounded by a protrusion at the downstream end of the first housing segment 302. The protrusion may serve as a stop for the distal end of the mouthpiece 102. As a result, this configuration for the pod outlet 304 facilitates receiving and aligning the distal end of the mouthpiece 102 (e.g., via the open side of the edge and its subsequent seating abutment against the protrusion at the downstream end of the first housing segment 302) Figure 11In a non-limiting embodiment, when the non-nicotine pod 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 pod outlet 304.

[0090] The downstream end of the first housing section 302 further defines at least one downstream recess. In an exemplary embodiment, the at least one downstream recess is in the form of a first downstream recess 306a and a second downstream recess 306b. The pod outlet 304 may be located between the first downstream recess 306a and the second downstream recess 306b. The first downstream recess 306a and the second downstream recess 306b are configured to engage with the first downstream protrusion 130a and the 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 at adjacent corners of the downstream sidewall of the through hole 150. The first downstream groove 306a and the second downstream groove 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 of the first downstream groove 306a and the second downstream groove 306b. The first downstream groove 306a can abut the corner of the downstream end face and the first side face, while the second downstream groove 306b can abut the corner of the downstream end face and the second side face. As a result, the edges of the first downstream groove 306a and the second downstream groove 306b adjacent to the first side face and the second side face, respectively, can be opened. In this case, as... Figure 18 As shown, each of the first downstream groove 306a and the second downstream groove 306b can be a three-sided groove.

[0091] The second housing section 308 has an upstream end that further defines (in addition to the pod inlet 322) a plurality of openings (e.g., a first power contact opening 325a, a second power contact opening 325b, and a data contact opening 327), said plurality of openings being configured to expose the connector module 320 within the non-nicotine pod assembly 300. Figures 20 to 21 The upstream end of the second housing section 308 further defines at least one upstream recess. In an exemplary embodiment, the at least one upstream recess is in the form of a first upstream recess 312a and a second upstream recess 312b. The pod inlet 322 may be located between the first upstream recess 312a and the second upstream recess 312b. The first upstream recess 312a and the second upstream recess 312b are configured to engage with the first upstream protrusion 128a and the 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 at adjacent corners of the upstream sidewall of the through hole 150. The depth of each of the first upstream groove 312a and the second upstream groove 312b can be greater than the depth of each of the first downstream groove 306a and the second downstream groove 306b. The end of each of the first upstream groove 312a and the second upstream groove 312b can also be more rounded than the end of each of the first downstream groove 306a and the second downstream groove 306b. For example, the first upstream groove 312a and the second upstream groove 312b can each be in the form of a U-shaped recess. 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 recess of the first upstream groove 312a and the second upstream groove 312b. The first upstream groove 312a can be adjacent to the corner of the upstream end face and the first side face, while the second upstream groove 312b can be adjacent to the corner of the upstream end face and the second side face. As a result, the edges of the first upstream groove 312a and the second upstream groove 312b, which are adjacent to the first side and the second side respectively, can be opened.

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

[0093] The non-nicotine pod assembly 300 can be manually activated by an adult smoker before being inserted into the device body 100. Alternatively, activation of the non-nicotine pod assembly 300 can be part of the insertion of the non-nicotine pod assembly 300 into the device body 100. In an exemplary embodiment, the second housing segment 308 of the pod body includes a perforator configured to release a non-nicotine vapor precursor formulation from a reservoir in the first housing segment 302 during activation of the non-nicotine pod 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 non-nicotine pod assembly 300, an adult smoker may (e.g., simultaneously or sequentially) press inward the first activation pin 314a and the second activation pin 314b before inserting the non-nicotine pod assembly 300 into the through-hole 150 of the device body 100. For example, the first activation pin 314a and the second activation pin 314b may be manually pressed until their ends are substantially flush with the upstream end face of the non-nicotine pod assembly 300. In an exemplary embodiment, the inward movement of the first activation pin 314a and the second activation pin 314b results in the reservoir seal being punctured or otherwise broken in order to release the non-nicotine vapor precursor formulation therefrom.

[0095] Alternatively, to activate the non-nicotine pod assembly 300, as part of the non-nicotine pod assembly 300 inserted into the device body 100, the non-nicotine pod assembly 300 is initially positioned such that the first upstream recess 312a and the second upstream recess 312b engage (e.g., upstream engagement) with the first upstream protrusion 128a and the second upstream protrusion 128b, respectively. Because 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 recess in the first upstream recess 312a and the second upstream recess 312b, the non-nicotine pod assembly 300 can then be pivoted relatively easily around the first upstream protrusion 128a and the second upstream protrusion 128b and enter the through-hole 150 of the device body 100.

[0096] Regarding the pivoting of the non-nicotine pod 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 oriented perpendicular to the longitudinal axis of the device body 100. During the initial positioning and subsequent pivoting of the non-nicotine pod assembly 300, the first activation pin 314a and the second activation pin 314b will contact the upstream sidewall of the through-hole 150 and transition from an extended state to a retracted state because the first activation pin 314a and the second activation pin 314b are (e.g., simultaneously) pushed into the second housing section 308 when the non-nicotine pod assembly 300 enters the through-hole 150. When the downstream end of the non-nicotine pod 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 will retract, and then when the positioning of the non-nicotine pod assembly 300 allows the first downstream protrusion 130a and the second downstream protrusion 130b of the device body 100 to engage (e.g., downstream engagement) with the first downstream groove 306a and the second downstream groove 306b of the non-nicotine pod assembly 300, the first downstream protrusion 130a and the second downstream protrusion 130b will elastically extend (e.g., rebound).

[0097] As described above, according to an exemplary 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 move a corresponding distance simultaneously in the same direction (e.g., downstream direction). Conversely, when the non-nicotine pod assembly 300 has been fully inserted for downstream engagement, the mouthpiece 102 will spring back simultaneously with the first downstream protrusion 130a and the second downstream protrusion 130b. In addition to the elastic engagement of the first downstream protrusion 130a and the second downstream protrusion 130b, when the non-nicotine pod assembly 300 is properly seated within the through-hole 150 of the device body 100, the distal end of the mouthpiece 102 is configured to also be biased against the non-nicotine pod assembly 300 (and aligned with the pod 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 non-nicotine pod assembly 300 is correctly seated within the through-hole 150 of the device body 100. When correctly seated, the non-nicotine pod assembly 300 will be mechanically, electronically, and fluidly connected to the device body 100. Although the non-limiting embodiments described herein depict upstream engagement of the non-nicotine pod assembly 300 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. The joining of the non-nicotine pod assembly 300 to the device body 100 and other aspects of the non-nicotine e-vaping device 500 are also described in U.S. Application No. 16 / 695,563 entitled “Non-nicotine pod Assemblies And Non-nicotine E-vaping Devices” (Atty. Dkt. No. 24000NV-000624-US), the entire contents of which are incorporated herein by reference.

[0099] Figure 20 yes Figure 19 A partial exploded view of the non-nicotine pod components. See also... Figure 20The first housing section 302 includes a vapor passage 316. The vapor passage 316 is configured to receive non-nicotine vapor generated during suction and is in fluid communication with the pod outlet 304. In an exemplary embodiment, the vapor passage 316 may gradually increase in size (e.g., diameter) as it extends toward the pod 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 non-nicotine pod assembly 300. For example, the insert 342 may be seated within the first housing section 302 such that the outer peripheral surface of the insert 342 engages along its edge with the inner surface of the first housing section 302 (e.g., via an interference fit), such that the interface between the outer 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 gas-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 gas-tight) containment for the non-nicotine vapor precursor formulation in the reservoir. For example, 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 pod inlet 322, a first power contact opening 325a, a second power contact opening 325b, a data contact opening 327, a first upstream recess 312a, a second upstream recess 312b, a first pin opening 315a, and a second pin opening 315b. As described above, the pod inlet 322 allows air to enter the non-nicotine pod assembly 300 during suction, while the first power contact opening 325a, the second power contact opening 325b, and the data contact opening 327 are configured to expose the first power contact 324a, the second power contact 324b, and the data contact 326 of the connector module 320, respectively. In an exemplary embodiment, the first power contact 324a and the second power contact 324b are mounted on the module housing 354 of the connector module 320. Furthermore, the data contact 326 may be disposed on a printed circuit board (PCB) 362. Furthermore, the pod inlet 322 may be located between the first upstream groove 312a and the second upstream groove 312b, while the contact openings (e.g., the first power contact opening 325a, the second power contact opening 325b, and the data contact opening 327) may be located between the first pin opening 315a and the second pin opening 315b. The first pin opening 315a and the second pin opening 315b are configured to receive the first activation pin 314a and the second activation pin 314b, respectively, which extend through the first pin opening and the second pin opening.

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

[0102] The non-nicotine pod assembly 300 defines a flow path from pod inlet 322 to pod outlet 304. The flow path through the non-nicotine pod assembly 300 (among others) includes: a first branch portion, a second branch portion, and a confluence portion. The pod inlet 322 is located upstream of the first and second branch portions of the flow path. Specifically, as... Figure 21 As shown, the sides (e.g., inlet sides) of the module housing 354 (and connector module 320) above the first power contact 324a and the second power contact 324b are recessed to define the separator 329 and the initial segments of the first and second branch portions of the flow path. In an exemplary embodiment, the separator 329 is recessed from the outer surface of the module housing 354 (e.g., Figure 21 The side of the module housing 354 above the first power contact 324a and the second power contact 324b can also be regarded as the inlet portion defining the flow path, which is located downstream of the pod 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. Alternatively, the pair of longer sides of the module housing 354 may also be referred to herein as lateral faces. Figure 21 The sectors of the module housing 354 covered by the printed circuit board (PCB) 362 (but such as Figure 30 (As shown) defines a first branch portion and a second branch portion of the flow path, as well as other segments of the confluence portion. The other segments of the first branch portion and the second branch portion 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 branch portion and the second branch portion merge to form the confluence portion of the flow path.

[0104] When the connector module 320 is seated into the receiving cavity in the downstream side of the second housing section 308, the non-recessed side of the module housing 354 intersects with 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 seating of the connector module 320 into the receiving cavity of the second housing section 308 can be achieved through a close-fitting arrangement, such that the connector module 320 remains substantially stationary within the non-nicotine pod assembly 300.

[0105] like Figure 22 As shown, connector module 320 includes a suction core 338 configured to transfer a non-nicotine vapor precursor formulation to heater 336. Heater 336 is configured to heat the non-nicotine vapor precursor formulation during aspiration to generate non-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 power contact 324a, while the other end of heater 336 (e.g., a second end) may be connected to a second power contact 324b. In an exemplary embodiment, heater 336 includes a folded heating element. In this case, suction core 338 may have a planar form, configured to be held by the folded heating element. When the non-nicotine pod assembly 300 is assembled, suction core 338 is configured to be in fluid communication with absorbent material 346 (e.g., ...). Figure 25 This allows the non-nicotine vapor precursor formulation located in the absorbent material 346 (when the non-nicotine capsule assembly 300 is activated) to be transferred via capillary action to the absorbent core 338.

[0106] In an exemplary embodiment, the incoming airflow entering the non-nicotine pod assembly 300 through the pod inlet 322 is guided by a separator 329 into a first branch portion and a second branch portion of the flow path. The separator 329 may be wedge-shaped and configured (e.g., at least initially) to split the incoming airflow into opposite directions. The split airflow may include a first airflow (flowing through the first branch portion of the flow path) and a second airflow (flowing through the second branch portion of the flow path). After being split by the separator 329, the first airflow travels along the inlet side and continues flowing around a corner toward a first cross face, and along the first cross face toward a first curved path 330a. Similarly, the second airflow travels along the inlet side and continues flowing around a corner toward a second cross face, and along the second cross face toward a second curved path 330b (e.g., Figure 30 The confluence of the flow paths is located downstream of the first branch and the second branch. The heater 336 and the suction core 338 are located downstream of the confluence of the flow paths. Therefore, the first airflow and the second airflow converge at the confluence of the flow paths (e.g., Figure 30 In the confluence path 330c, they combine to reach the module outlet 368 (e.g., through the module housing 354) in the module housing 354. Figure 28 (The middle mark) forms a combined flow before reaching the heater 336 and the suction core 338.

[0107] Figure 23 It involves Figure 22 An exploded view of the suction core and heater. See also... Figure 23 The absorbent core 338 can be a fiber pad or other structure with pores / gap designed for capillary action. Furthermore, the absorbent core 338 can have a rectangular shape, but exemplary embodiments are not limited thereto. For example, the absorbent core 338 can have an alternative shape of an irregular hexagon, wherein two sides face inward and are angled toward the heater 336. The absorbent core 338 can be manufactured into the desired shape or cut from a larger sheet of material into such a shape. In the case where the lower section of the absorbent core 338 gradually tapers toward the winding section of the heater 336 (e.g., a hexagonal shape), the possibility of non-nicotine vapor precursor formulations being present in portions of the absorbent core 338 that continuously escape 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 clamp the absorbent core 338. The folded heating element may also include at least one pointed tip 337 configured to protrude into the absorbent core 338.

[0108] In an exemplary 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 electric current may be supplied from a power source (e.g., a battery) within the device body 100 and delivered to heater 336 via a first power contact 324a or a second power 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 plate (e.g., metal, alloy) that is stamped to cut a winding pattern therefrom. The winding pattern may have curved segments that alternate with horizontal segments to allow the horizontal segments to extend parallel and bend back and forth. Furthermore, the width of each horizontal segment of the winding pattern may be substantially equal to the spacing between adjacent horizontal segments of the winding pattern, but exemplary embodiments are not limited thereto. To obtain the form of heater 336 shown in the figures, the winding pattern can be folded to clamp the absorbent wick 338. Furthermore, when the tip 337 is part of heater 336, the protrusion corresponding to the tip 337 bends (e.g., inward and / or orthogonally) before the winding pattern is folded. Due to the tip 337, the possibility of the absorbent wick 338 slipping out of heater 336 is reduced or prevented. The heater and its associated structure are discussed in more detail in U.S. Patent Application No. 15 / 729,909, filed October 11, 2017, entitled “Folded Heater For Electronic Vaping Device” (Atty. Dkt. No. 24000-000371-US), the entire contents of which are incorporated herein by reference.

[0110] Figure 24 It involves Figure 17 An exploded view of the first shell section of the non-nicotine pod assembly. See also... Figure 24The first housing section 302 includes a vapor passage 316. The vapor passage 316 is configured to receive non-nicotine vapor generated by the heater 336 and is in fluid communication with the pod outlet 304. In an exemplary embodiment, the vapor passage 316 may gradually increase in size (e.g., diameter) as it extends toward the pod 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 non-nicotine pod assembly 300. For example, the insert 342 may be seated within the first housing section 302 such that the outer peripheral surface of the insert 342 engages along its edge with the inner surface of the first housing section 302 (e.g., via an interference fit), such that the interface between the outer 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 gas-tight). Furthermore, a seal 344 is attached to the upstream side of the insert 342 to close the reservoir outlet in the insert 342, thereby providing a fluid-tight (e.g., liquid-tight and / or gas-tight) containment for the non-nicotine vapor precursor formulation in the reservoir. In this document, the first housing section 302, the insert 342, and the 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 gas-tightly seal the non-nicotine vapor precursor formulation until the non-nicotine capsule assembly 300 is activated.

[0111] In an exemplary embodiment, the insert 342 includes a retainer portion protruding from the upstream side (such as...). Figure 24 (as shown) and the connector portion protruding from the downstream side (in Figure 24 (Hidden out of sight). The retainer portion of the insert 342 is configured to retain the absorbent material 346 (e.g., Figure 25The connector portion of insert 342 is configured to engage with the vapor passage 316 of the first housing section 302. The connector portion of insert 342 may be configured to sit within the vapor passage 316, thus engaging the interior of the vapor passage 316. Alternatively, the connector portion of insert 342 may be configured to receive the vapor passage 316, thus engaging the exterior of the vapor passage 316. Insert 342 also defines a reservoir outlet through which the non-nicotine vapor precursor formulation flows when the seal 344 is punctured during activation of the non-nicotine pod assembly 300. The retainer portion and connector portion of insert 342 may be located between the reservoir outlets (e.g., the first and second reservoir outlets), but exemplary embodiments are not limited thereto. Furthermore, insert 342 defines a vapor conduit extending through the retainer portion and connector portion. As a result, when the insert 342 is seated within the first housing section 302, the steam conduit of the insert 342 will align with and fluidly communicate with the steam passage 316 to form a continuous path through the reservoir to the pod outlet 304 for the non-nicotine vapor generated by the heater 336 during suction.

[0112] A seal 344 is attached to the upstream side of an insert 342 to cover the reservoir outlet in the insert 342. In an exemplary embodiment, the seal 344 defines an opening (e.g., a central opening) configured to provide a relevant 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 activation pin 314a and the second activation pin 314b of the non-nicotine pod assembly 300, the two pierced sections of the seal 344 act as valves pushed into the reservoir, thereby 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 flat form and only one opening (e.g., a central opening). Seal 344 is designed to be strong enough to remain intact during normal movement and / or handling of the non-nicotine pod assembly 300 to prevent premature / accidental breakage. For example, seal 344 may be a coated foil (e.g., aluminum-backed polyethylene terephthalate (PET)).

[0113] Figure 25 It involves Figure 17 A partially exploded view of the second shell section of the non-nicotine pod assembly. See also... Figure 25The second housing section 308 is configured to include various components configured to release, receive, and heat a non-nicotine vapor precursor formulation. For example, a first activation pin 314a and a second activation pin 314b are configured to pierce a reservoir in the first housing section 302 to release the non-nicotine vapor precursor formulation. Each of the first activation pin 314a and the second activation 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 exemplary embodiment, the distal ends of the first activation pin 314a and the second activation 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 out of sight within the non-nicotine capsule assembly 300. Furthermore, each of the first activation pin 314a and the second activation pin 314b has a proximal end adjacent to and upstream of the seal 344 prior to activation of the non-nicotine capsule 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 non-nicotine capsule assembly 300, the proximal end of each of the first activation pin 314a and the second activation pin 314b will pass through the insert 342 and thus pierce the seal 344, which will release the non-nicotine vapor precursor formulation 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 pin 314a and the second activation pin 314b will be discussed in more detail herein.

[0114] Absorbent material 346 may be seated within a retainer (e.g., a top cap retainer 345). Absorbent material 346 is also located downstream of and in fluid communication with the absorbent 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 a ring-shaped form, but the exemplary embodiment is not limited thereto. Figure 25 The absorbent material 346, as depicted, 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 absorbent 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 induce 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 retain a quantity of non-nicotine vapor precursor formulation released from the reservoir when the non-nicotine capsule assembly 300 is activated.

[0115] The absorbent core 338 is positioned within the non-nicotine pod assembly 300 to be in fluid communication with the absorbent material 346, allowing the non-nicotine vapor precursor formulation to be drawn from the absorbent material 346 to the heater 336 via capillary action. The absorbent core 338 may be in physical contact with the upstream side of the absorbent material 346 (e.g., based on...). Figure 25 The view shown shows the bottom of the absorbent material 346. Furthermore, the absorbent core 338 may be aligned with the diameter of the absorbent material 346, but the exemplary embodiments are not limited thereto.

[0116] like Figure 25 (and the previous ones) Figure 23 As shown, heater 336 can have a folded configuration to grip and establish thermal contact with the opposing surfaces of wick 338. Heater 336 is configured to heat wick 338 during aspiration to generate non-nicotine vapor. To facilitate this heating, a first end of heater 336 can be electrically connected to a first power contact 324a, and a second end of heater 336 can be electrically connected to a second power contact 324b. As a result, current can be supplied from a power source (e.g., a battery) within the device body 100 and delivered to heater 336 via the first power contact 324a or the second power contact 324b. For brevity, details already discussed above (e.g., in conjunction with...) will not be repeated in this section. Figures 21 to 22 Other related details of the connector module 320. In an exemplary embodiment, although in Figure 25 Hidden from view, the second housing section 308 includes a receiving cavity for the connector module 320. In general, the second housing section 308 and the components discussed above therein can be referred to as the second section. During inhalation, non-nicotine vapor generated by the heater 336 is drawn into the vapor outlet through the vapor conduit of the insert 342, the vapor passage 316 of the first housing section 302, the pod outlet 304 of the non-nicotine pod assembly 300, and through the vapor passage 136 of the mouthpiece 102.

[0117] Figure 26 yes Figure 25 An exploded view of the cap retainer in the diagram. See also... Figure 26The cap holder 345 includes a base portion 345a and a cylindrical portion 345b. In an exemplary embodiment, the base portion 345a and the cylindrical portion 345b are integrally formed. The cylindrical portion 345b defines a well configured to receive absorbent material 346. Optionally, the inner lower surface of the well may include a protrusion (or other projection) that supports the absorbent material 346 such that the absorbent material 346 does not simply slide across or droop from the cap holder 345 (e.g., when a non-nicotine vapor precursor formulation released from the reservoir saturates the absorbent material 346). Furthermore, the base portion 345a defines a recess configured to receive a gasket 345c. Additionally, 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 cap retainer 345 is assembled within the non-nicotine pod assembly 300, the integrally formed posts can abut the bottom surface of the insert 342, with a portion of the seal 344 in between.

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

[0119] In an exemplary 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 portion (e.g., the proximal portion) of the first actuator 350a and the second actuator 350b, respectively. Mounting or attachment may be achieved via snap-fit ​​connection, interference fit (e.g., friction fit) connection, adhesive, or other suitable coupling techniques. The tip of each of the first blade 348a and the second blade 348b may have one or more curved or concave edges that taper upwards to a point. For example, each of the first blade 348a and the second blade 348b may have two points with a concave edge therebetween and a curved edge adjacent to each point. The radii of curvature of the concave edge and the curved edge may be the same, but 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), which is cut out or otherwise shaped to have a desired profile and bent to 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 portions integrally formed (or mounted) with the first blade 348a, the second blade 348b, and the first actuator 350a and the second actuator 350b can correspond to the dimensions and shapes of the reservoir outlet in the insert 342. Furthermore, as... Figure 27 As shown, the first activation pin 314a and the second activation pin 314b may include protruding edges (e.g., curved inner lips facing each other) configured to push two piercing sections of the seal 344 into the reservoir when the first blade 348a and the second blade 348b are inserted into the reservoir. In a non-limiting embodiment, when the first activation pin 314a and the second activation pin 314b are fully inserted into the non-nicotine pod assembly 300, the two valves (from the two piercing 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 activation pin 314a and the second activation pin 314b. As a result, the possibility of the two piercing openings in the seal 344 (due to the two valves of the two piercing sections) becoming obstructed can be reduced or prevented. Furthermore, the first activation pin 314a and the second activation pin 314b may be configured to guide the non-nicotine vapor precursor formulation from the reservoir to the absorbent material 346 within the cap retainer 345.

[0121] The lower portion (e.g., distal end) of each of the first actuator 350a and the second actuator 350b is configured to extend through the bottom section (e.g., upstream end) of the second housing section 308. 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 seated in an annular groove in the respective shaft 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. As a result, when the first activation pin 314a and the second activation pin 314b are pushed inward to activate the non-nicotine capsule 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 corresponding openings in the second housing section 308 while maintaining their respective seals. This helps to reduce or prevent leakage of the non-nicotine vapor precursor formulation through the openings in the second housing section 308 for the first activation pin 314a and the second activation pin 314b. The first O-ring 352a and the second O-ring 352b can be formed of silicone.

[0122] A perforator for the non-nicotine pod assembly 300 may include notches configured to engage with a clip to prevent premature actuation of the perforator. For example, the axes of a first activation pin 314a and a second activation pin 314b may define, respectively, a first notch 351a and a second notch 351b, configured to engage with such a clip. In an exemplary embodiment, the clip may be a planar structure defining a first slot and a second slot configured to engage with the first notch 351a and the second notch 351b, respectively. When engaged (via the first notch 351a and the second notch 351b, respectively) with the axes of the first activation pin 314a and the second activation pin 314b, the clip may be adjacent to a second housing segment 308, thereby preventing the first activation pin 314a and / or the second activation pin 314b from being unintentionally pushed into the non-nicotine pod assembly 300. As a result, (e.g., during transport and / or handling) the first activation pin 314a and the second activation pin 314b can be adequately restrained to reduce or prevent the possibility of premature actuation. When the non-nicotine pod assembly 300 is to be activated, the clip can be removed at the appropriate time (e.g., by an adult smoker).

[0123] Figure 28 yes Figure 22 A perspective view of the connector module, which does not have a suction 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. See also Figures 28 to 30 The module housing 354 forms the frame of the connector module 320. Among other things, the module housing 354 defines a separator 329 and a flow path for air to be drawn into the non-nicotine pod assembly 300. When assembled within the non-nicotine pod 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 suction core 338 (e.g., Figure 22 The module housing 354 and the top cap retainer 345 (at least partially) can be enclosed. Furthermore, the internal space defined by the module housing 354 and the top cap retainer 345 (where the heater 336 and the suction core 338 are disposed) during assembly can be considered a heating chamber. The heating chamber is in fluid communication with a flow path in the upstream side of the module housing 354 via the module outlet 368.

[0124] As described above, the flow path for air inhaled into the non-nicotine pod assembly 300 includes a first branch portion, a second branch portion, and a confluence portion defined by the module housing 354. In an exemplary embodiment, the first and second branch portions are symmetrical portions bisected by an axis corresponding to the confluence portion of the flow path. For example, as... Figure 30 As shown, the first branch, the second branch, and the confluence portion can each include a first curved path 330a, a second curved path 330b, and a confluence path 330c, respectively. The first curved path 330a and the second curved path 330b can be substantially U-shaped paths, while the confluence path 330c can be substantially linear. Based on an axis corresponding to the confluence path 330c and aligned with the top of the separator 329, the first branch of the flow path can be a mirror image of the second branch of the flow path. During suction, the air drawn in through the pod inlet 322 can be divided by the separator 329 and initially flows out of the separator 329 in opposite directions, followed by parallel subsequent airflows. Each airflow (via the first curved path 330a and the second curved path 330b) then makes a U-turn and (via the confluence path 330c) forms a combined flow, which returns to the separator 329 before entering the heating chamber through the module outlet 368. The heater 336 and the suction core 338 can be positioned such that both sides are exposed to the airflow through the module outlet 368 substantially equally. During suction, the generated non-nicotine vapor is carried into the vapor passage 316 by the airflow flowing through the heating chamber.

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

[0126] The partition 370 may be in the form of a rod extending transversely (e.g., bisecting) the module outlet 368. Regarding dimensions, the partition 370 may have a thickness of approximately 150–250 µm (e.g., 200 µm). The thickness of the partition 370 corresponds to the degree to which it obstructs the module outlet 368. Therefore, the thickness of the partition 370 and / or the dimensions of the module outlet 368 can be adjusted to provide the required inhalation resistance (e.g., 25 mmH2O) for the non-nicotine electronic cigarette device 500. Furthermore, the width of the partition 370 may be between 525–875 µm (e.g., 700 µm). The width may allow the partition 370 to extend along most or all of the channel defined by the module outlet 368. Additionally, assuming a circular cross-section of the module outlet 368, the length of the partition 370 may correspond to the diameter of the module outlet 368. Alternatively, if the module outlet 368 has an elliptical cross-section, the length of the partition 370 may correspond to the axis of the module outlet 368 (e.g., the minor axis, the major axis).

[0127] like Figures 29 to 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 exemplary embodiment is not limited thereto. The module housing 354 may define a pair of shallow recesses and a pair of orifices to facilitate mounting of the first power contact 324a and the second power contact 324b. During assembly, the contact surface of each of the first power contact 324a and the second power contact 324b may sit 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 Furthermore, 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 28Subsequently, heater 336 can be connected to the contact leg of each of the first power contact 324a and the second power contact 324b.

[0128] Printed circuit board (PCB) 362 includes: a plurality of data contacts 326 on its upstream side (e.g., Figure 30 ) and various electronic components (including sensor 364) on its downstream side (e.g., Figure 29 Sensor 364 can be positioned on a printed circuit board (PCB) 362 such that sensor 364 is located within a convergence path 330c defined by module housing 354. In an exemplary 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 through data contact opening 327 of the second housing segment 308. Subsequently, module housing 354 (on which first power contact 324a, second power contact 324b, heater 336, and suction core 338 are mounted) can be inserted into the receiving cavity such that first power contact 324a and second power contact 324b are exposed through first power contact opening 325a and 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) can be fixed to the module housing 354 (e.g., to form a single integral structure) to cover the first bending path 330a, the second bending path 330b, the confluence path 330c, and the module outlet 368.

[0129] As described above, the module outlet 368 can be an inhalation resistance (RTD) port. In this configuration, the inhalation resistance for the non-nicotine electronic cigarette device 500 can be adjusted by changing the size of the module outlet 368 (rather than changing the size of the pod inlet 322). In an exemplary embodiment, the size of the module outlet 368 can be selected such that the inhalation resistance is between 20 and 100 mmH2O (e.g., between 25 and 50 mmH2O). For example, a 1.0 mm diameter of the module outlet 368 can result in an inhalation resistance of 88.3 mmH2O. In another case, a 1.1 mm diameter of the module outlet 368 can result in an inhalation resistance of 73.6 mmH2O. In yet another case, a 1.2 mm diameter of the module outlet 368 can result in an inhalation resistance of 58.7 mmH2O. In yet another case, a 1.3 mm diameter of the module outlet 368 can result in an inhalation resistance of 40–43 mmH2O. It is worth noting that, due to its internal arrangement, the size of the module outlet 368 can be adjusted without affecting the external aesthetics of the non-nicotine pod assembly 300, thereby allowing for more standardized product design for non-nicotine pod assemblies with various inhalation resistances (RTDs), while also reducing the possibility of unintentionally blocking the air intake.

[0130] Other aspects of the device body 100, the non-nicotine pod assembly 300, and the non-nicotine e-vaping device 500 may also be described in concurrently filed U.S. Application No. 16 / 696,189 entitled “Non-nicotine pod Assemblies And Non-nicotine E-vaping Devices” (Atty. Dkt. No. 24000NV-000619-US) and concurrently filed U.S. Application No. 16 / 695,515 entitled “Non-nicotine pod Assemblies And Non-nicotine e-vaping Devices” (Atty. Dkt. No. 24000NV-000613-US), the entire contents of which are incorporated herein by reference.

[0131] In an exemplary embodiment, the non-nicotine vapor preformulation does not include or originate from tobacco. The non-nicotine compound in the non-nicotine vapor preformulation may be a liquid or a portion of a liquid, or included therein, including extracts, oils, alcohols, tinctures, suspensions, dispersions, colloids, generally non-neutral (weakly acidic or weakly basic) solutions, or combinations thereof. During the preparation of the non-nicotine vapor preformulation, the non-nicotine compound may be infused, mixed, or otherwise combined with other components of the non-nicotine vapor preformulation.

[0132] In exemplary embodiments, non-nicotine compounds undergo a slow, natural decarboxylation process over a longer period of time at relatively low temperatures, including at or below room temperature (e.g., 72°F). Furthermore, if exposed to higher temperatures (especially in the range of approximately 175°F or higher) at relatively low pressures (e.g., 1 atmosphere) for a period of time (minutes or hours), non-nicotine compounds may undergo a significantly increased decarboxylation process (e.g., 50% or higher decarboxylation). Temperatures of approximately 240°F or higher can result in rapid or transient decarboxylation at a relatively high rate, but further increases in temperature can lead to impairment of some or all of the chemical properties of the non-nicotine compound.

[0133] Non-nicotine vapor precursor formulations may contain non-nicotine compounds that provide medically acceptable therapeutic effects (e.g., treatment of pain, nausea, seizures, mental disorders). Details of the treatment methods can be found in U.S. Application No. 15 / 845,501, filed December 18, 2017, entitled “VAPORIZING DEVICES AND METHODS FOR DELIVERING A COMPOUND USING THE SAME,” the disclosure of which is incorporated herein by reference in its entirety.

[0134] In an exemplary embodiment, at least one flavoring agent is present in an amount ranging from about 0.2% to about 15% by weight (e.g., about 1% to 12%, about 2% to 10%, or about 5% to 8%), based on the total weight of the non-nicotine vapor precursor preparation. The at least one flavoring agent may be at least one of a natural flavoring agent, an artificial flavoring agent, or a combination of natural and artificial flavoring agents. For example, at least one flavoring agent may include menthol, wintergreen, peppermint, cinnamon, cloves, combinations thereof, and / or extracts thereof. Furthermore, flavoring agents may be included to provide other herbal spices, fruit spices, nut spices, spirits spices, roasting spices, mint spices, flavoring spices, combinations thereof, and any other desired spices.

[0135] While 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 the invention, and it will be apparent to those skilled in the art that all such modifications are intended to be included within the scope of the following claims.
