[0038] This document discloses some detailed example embodiments. However, the specific structural and functional details disclosed herein are merely representative and for the purpose of describing example embodiments. However, example embodiments can be implemented in many alternative forms and should not be considered as limited to the example embodiments listed herein.

[0039] Therefore, while the exemplary embodiments are capable of various modifications and alternatives, they 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 the exemplary embodiments to the specific forms disclosed; rather, the exemplary embodiments cover all modifications, equivalents, and alternatives thereof. Throughout the description of the drawings, the same reference numerals denote the same elements.

[0040] 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.

[0041] 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.

[0042] 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 orientations 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.

[0043] 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” specify the presence of the stated features, integrals, steps, operations, and / or elements, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, and / or groups thereof.

[0044] 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 range of manufacturing or operational tolerances (e.g., ±10%).

[0045] 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 stated 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.

[0046] 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.

[0047] 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.

[0048] Figure 1 This 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 3The 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, for example, 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] The front cover 104 also defines a secondary opening configured to receive a light guide arrangement. The secondary opening may resemble a 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 housing 114 and a button housing 122. The light guide housing 114 is configured to expose a light guide lens 116, while the button housing 122 is configured to expose a first button lens 124 and a second button lens 126 (e.g., ...). Figure 16 The upstream portion of the first button lens 124 and the button housing 122 can form the first button 118. Similarly, the downstream portion of the second button lens 126 and the button housing 122 can form the second button 120. The button housing 122 can be a single structure or two separate structures. In the latter case, the first button 118 and the second button 120 can move with more independent tactile feedback when pressed.

[0053] 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 may be a power button, and the second button 120 may be an intensity button. Although two buttons are shown in the accompanying drawings with respect to the light guide device, it should be understood that more (or fewer) buttons may be provided depending on the available features and desired user interface.

[0054] 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.

[0055] 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.

[0056] 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 on the front of the non-nicotine electronic cigarette device 500, a light guide arrangement (e.g., including a button) may also be provided on the rear of the non-nicotine electronic cigarette device 500.

[0057] 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 clip may be in the form of a lug with an opening configured to receive a corresponding mating member of the frame 106 (e.g., a protrusion with a bevel). Alternatively, the front cover 104 and / or rear cover 108 may 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.

[0058] 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 2As 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.

[0059] 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.

[0060] Figure 5 yes Figure 1 A remote view of a non-nicotine electronic cigarette device. See also Figure 5 The 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 an electronic device, such as a telephone, via an application (app) installed on that device. In this case, the 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).

[0061] 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 inlet. See also... Figures 6 to 7As 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 the 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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 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.

[0066] 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).

[0067] 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.

[0068] 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.

[0069] 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.

[0070] Figure 11 yes Figure 10 Enlarged perspective view of the through-hole. See also Figure 11The 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.

[0071] 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.

[0072] 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 12The device body 100 includes a device electrical connector 132 as its electrical contacts. The device electrical connector 132 includes power contacts and data contacts. The power contacts of the device electrical connector 132 are configured to supply power from the device body 100 to the non-nicotine capsule assembly 300. As shown, the power contacts of the device electrical connector 132 include a first pair of power contacts and a second pair of power contacts (they are positioned closer to the front cover 104 than the rear cover 108). The first pair of power contacts (e.g., the pair adjacent to the first upstream protrusion 128a) may be a single integral structure, distinct from the second pair of power contacts, and, upon assembly, includes two protrusions extending into the through-hole 150. Similarly, the second pair of power contacts (e.g., the pair adjacent to the second upstream protrusion 128b) may be a single integral structure, distinct from the first pair of power contacts, and, upon assembly, includes two protrusions extending into the through-hole 150. The first pair of power contacts and the second pair of 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.

[0073] 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 when assembled. The data contacts of the device electrical connector 132 can also be pulled-mounted and biased (e.g., 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.

[0074] Figure 13 It involves Figure 12A 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.

[0075] 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.

[0076] 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 (located within the device body 100 where the non-nicotine pod assembly 300 sits). The proximal end of vapor passage 136 may include a flared portion. Additionally, 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.

[0077] 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 15 The frame structure 112 includes an upstream sidewall and a downstream sidewall. The upstream sidewall of the frame structure 112 defines a connector opening 146. The connector opening 146 is configured to expose or receive a device electrical connector 132 of the device body 100. The downstream sidewall of the frame structure 112 defines a first downstream opening 148a, a second downstream opening 148b, and a third downstream opening 148c. The first downstream opening 148a and the second downstream opening 148b of the frame structure 112 are configured to receive a first downstream protrusion 130a and a second downstream protrusion 130b of the 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.

[0078] 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.

[0079] During assembly, the frame structure 112 can be secured to the frame 106 via a pair of lugs 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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 cavity 310. Figure 20 The downstream end of the pod body defines a pod outlet 304, which is in fluid communication with a cavity 310 at the upstream end. A connector module 320 is configured to sit within the cavity 310 of the pod body. The connector module 320 includes an outer surface and side surfaces. The outer surface of the connector module 320 forms the exterior of the pod body.

[0084] The outer surface of connector module 320 defines a pod inlet 322. The pod inlet 322 (through which air enters during suction) is in fluid communication with a pod outlet 304 (through which non-nicotine vapor exits during suction). The pod inlet 322 is as follows: Figure 19 The example shown is in the form of a slot. However, it should be understood that the exemplary embodiment is not limited to this, and other forms are also possible. When the connector module 320 is seated within the cavity 310 of the pod body, the outer surface of the connector module 320 remains visible, while most of the sides of the connector module 320 are obscured so that only a portion is visible through the pod entrance 322 at a given angle.

[0085] The outer surface of 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 pair of power contacts of the device electrical connector 132 of the device body 100 (e.g., ...). Figure 12 The second power contact 324b of the non-nicotine pod assembly 300 is electrically connected to the second pair of power contacts 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 pair of power contacts of the device electrical connector 132 of the device body 100 (e.g., adjacent to the first upstream protrusion 128a). Figure 12 A pair of contacts adjacent to the second upstream protrusion 128b are 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 rows of 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.

[0086] 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 may be considered 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 relative to each other. The upstream and downstream end faces may also be angled inwards relative to each other. Due to 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 capsule component 300 being incorrectly inserted into the device body 100 can be reduced or prevented.

[0087] 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 sitting on the open side of the edge and its subsequent abutment against the protrusion at the downstream end of the first housing segment 302) Figure 11 In 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 help form a seal around the pod outlet 304.

[0088] 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.

[0089] The second housing section 308 has an upstream end defining the cavity 310. Figure 20Cavity 310 is configured to receive connector module 320. Figure 21 Furthermore, the upstream end of the second housing section 308 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 12 As 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.

[0090] 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 it, 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.

[0091] 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 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.

[0092] 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.

[0093] 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 with the first upstream protrusion 128a and the second upstream protrusion 128b, respectively (e.g., upstream engagement). 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.

[0094] 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).

[0095] 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 to facilitate 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).

[0096] 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-nicotinepod Assemblies And Non-nicotine E-vaping Devices” (Atty.Dkt.No.24000NV-000624-US), the entire contents of which are incorporated herein by reference.

[0097] Figure 20 yes Figure 19 A perspective view of the non-nicotine pod assembly, which does not have a connector module. See also Figure 20 The upstream end of the second housing section 308 defines a cavity 310. As described above, the cavity 310 is configured (e.g., via an interference fit) to receive the connector module 320. In an exemplary embodiment, the cavity 310 is located between a first upstream recess 312a and a second upstream recess 312b, and also between a first activation pin 314a and a second activation pin 314b. In the absence of the connector module 320, the insert 342 ( Figure 24 ) and absorbent material 346 ( Figure 25 The insert 342 is visible. The absorbent material 346 is configured to retain the absorbent material 346. The absorbent material 346 is configured to absorb and retain a certain amount of the non-nicotine vapor precursor formulation released from the reservoir when the non-nicotine capsule assembly 300 is activated. The insert 342 and the absorbent material 346 will be discussed in more detail herein.

[0098] Figure 21 yes Figure 19 A perspective view of the connector module in the image. Figure 22 yes Figure 21 Another perspective view of the connector module. (Reference) Figures 21 to 22The overall frame of connector module 320 includes module housing 354 and panel 366. Furthermore, connector module 320 has multiple surfaces, including an outer surface and side surfaces, wherein the outer surface is adjacent to the side surfaces. In an exemplary embodiment, the outer surface of connector module 320 is composed of an upstream surface of panel 366, a first power contact 324a, a second power contact 324b, and a data contact 326. The side surfaces of connector module 320 are part of module housing 354. The side surfaces of connector module 320 define a first module inlet 330 and a second module inlet 332. Additionally, the two transverse surfaces adjacent to the side surfaces (also part of module housing 354) may include rib structures (e.g., extruded ribs) configured to facilitate an interference fit when connector module 320 is seated within the cavity 310 of the pod body. For example, each of the two transverse surfaces may include a pair of rib structures that taper gradually from panel 366. As a result, when the connector module 320 is pressed into the cavity 310 of the pod body, the module housing 354 will encounter increasing resistance through friction between the rib structure and the transverse wall of the cavity 310. When the connector module 320 is seated inside the cavity 310, the panel 366 can be substantially flush with the upstream end of the second housing section 308. Furthermore, the sides of the connector module 320 (which define the first module inlet 330 and the second module inlet 332) will face the sidewall of the cavity 310.

[0099] The panel 366 of the connector module 320 may have a recessed edge 328 that engages with a corresponding side surface of the cavity 310 to define a pod inlet 322. However, it should be understood that the exemplary embodiments are not limited thereto. For example, the panel 366 of the connector module 320 may alternatively be configured to completely define the pod inlet 322. The sides of the connector module 320 (defining the first module inlet 330 and the second module inlet 332) and the sidewalls of the cavity 310 (facing the sides) define an intermediate space between them. The intermediate space is located downstream of the pod inlet 322 and upstream of the first module inlet 330 and the second module inlet 332. Thus, in the exemplary embodiments, the pod inlet 322 is in fluid communication with the first module inlet 330 and the second module inlet 332 via the intermediate space. The first module inlet 330 may be larger than the second module inlet 332. In this configuration, when air is received by the pod inlet 322 during suction, the first module inlet 330 may receive the main stream (e.g., a larger flow) of the incoming air, while the second module inlet 332 may receive the secondary stream (e.g., a smaller flow) of the incoming air.

[0100] like Figure 22As 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 may be mounted in connector module 320 via contact core 334. 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 connector module 320 is seated in the cavity 310 of the pod body, the absorbent core 338 is configured to be in fluid communication with the absorbent material 346, such that (when the non-nicotine pod assembly 300 is activated) the non-nicotine vapor precursor formulation located in the absorbent material 346 is transferred to the absorbent core 338 via capillary action.

[0101] Figure 23 It involves Figure 22 An exploded view of the suction core, heater, electrical leads, and contact core. 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 an irregular hexagonal shape, but the exemplary embodiments are not limited thereto. The absorbent core 338 can be made hexagonal or cut into this shape from a larger sheet of material. Because the lower section of the absorbent core 338 gradually tapers towards the winding section of the heater 336, the possibility that non-nicotine vapor precursor formulations may be 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.

[0102] 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 and a first electrical lead 340a (or via a second power contact 324b and a second electrical lead 340b).

[0103] 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 zigzag 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 may be folded to clamp the absorbent core 338.

[0104] The heater 336 can be secured to the contact core 334 using a first electrical lead 340a and a second electrical lead 340b. The contact core 334 is formed of an insulating material and configured to electrically isolate the first electrical lead 340a from the second electrical lead 340b. In an exemplary embodiment, the first electrical lead 340a and the second electrical lead 340b each define a recess configured to engage with a corresponding protruding member of the contact core 334. Once engaged, a first end and a second end of the heater 336 can be secured (e.g., welded, soldered, brazed) to the first electrical lead 340a and the second electrical lead 340b, respectively. The contact core 334 can then be seated into a corresponding socket in the module housing 354 (e.g., via an interference fit). When the connector module 320 is assembled, the first electrical lead 340a electrically connects the first end of the heater 336 to a first power contact 324a, while the second electrical lead 340b electrically connects the second end of the heater 336 to a second power contact 324b. 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.

[0105] 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. A package 318, 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 package 318 may be disposed on the edge of the first housing section 302. Insert 342 can be seated within the first housing section 302 such that the outer peripheral surface of 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 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.

[0106] In an exemplary embodiment, the insert 342 includes a retainer portion protruding from the upstream side (e.g., Figure 24 (as shown) and the connector portion protruding from the downstream side (in Figure 24 (Hidden out of sight). The retainer portion of the insert 342 is configured to retain the absorbent material 346, while the connector portion of the insert 342 is configured to engage with the vapor passage 316 of the first housing section 302. The connector portion of the insert 342 may be configured to sit within the vapor passage 316 and thus engage the interior of the vapor passage 316. Alternatively, the connector portion of the insert 342 may be configured to receive the vapor passage 316 and thus engage with the exterior of the vapor passage 316. When the seal 344 is punctured during activation of the non-nicotine pod assembly 300 (e.g. Figure 24 As shown, insert 342 also defines a reservoir outlet through which the non-nicotine vapor precursor formulation flows. The retainer portion and connector portion of insert 342 may be located between the reservoir outlets (e.g., first and second reservoir outlets), but the exemplary embodiment is not limited thereto. Furthermore, insert 342 defines a vapor conduit extending through the retainer portion and connector portion. As a result, when insert 342 is seated within the first housing section 302, the vapor conduit of insert 342 will align with and fluidly communicate with the vapor passage 316 to form a continuous path through the reservoir to the pod outlet 304 for the non-nicotine vapor generated by heater 336 during suction.

[0107] A seal 344 is attached to the upstream side of the 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 for receiving a retainer portion (which projects from the upstream side of the insert 342) when the seal 344 is attached to the insert 342. Figure 24 It should be understood that the seal 344 is shown in a punctured state. Specifically, when punctured by the first activation pin 314a and the second activation pin 314b of the non-nicotine pod assembly 300, the two punctured sections of the seal 344 will act as valves (e.g., Figure 24 The insert 344 is 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 the unpierced state, the seal 344 will have a flat form and only one opening (e.g., the central opening). The 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 avoid premature / unintentional breakage. For example, the seal 344 may be a coated foil (e.g., aluminum-backed polyethylene terephthalate (PET)).

[0108] Figure 25 It involves Figure 17 A partially exploded view of the second shell section of the non-nicotine pod assembly. See also... Figure 25 The 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 opening 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 17The remaining portions 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.

[0109] Absorbent material 346 is configured to engage with the retainer portion of 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 As depicted, the absorbent material 346 can resemble a hollow cylinder. In this case, the outer diameter of the absorbent material 346 can be substantially equal to (or slightly larger than) the length of the 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. Furthermore, although in Figure 25 Concealed from view, the downstream side of the second housing section 308 may define a recess configured to receive and support absorbent material 346. An example of such a recess could be a circular chamber in fluid communication with and downstream of cavity 310. 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 pod assembly 300 is activated.

[0110] 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.

[0111] like Figure 25 (and previous ones) Figure 23As 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 via a first electrical lead 340a, and a second end of heater 336 can be electrically connected to a second power contact 324b via a second electrical lead 340b. 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 and the first electrical lead 340a (or via the second power contact 324b and the second electrical lead 340b). The first electrical lead 340a and the second electrical lead 340b (in...) Figure 23 (as shown in the diagram) can be engaged with contact core 334 (e.g.) Figure 25 (As shown). Further details regarding other aspects of the connector module 320 (which is configured to sit within the cavity 310 of the second housing section 308) have been discussed above (e.g., in conjunction with...). Figures 21 to 22 For the sake of brevity, this will not be repeated in this section. During inhalation, the 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 the vapor passage 136 of the mouthpiece 102.

[0112] Figure 26 yes Figure 25 An exploded diagram of the activation pin. See also: Figure 26 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 26 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.

[0113] In an exemplary embodiment, the first blade 348a and the second blade 348b are configured to be mounted or attached, respectively, to the upper portion (e.g., the proximal portion) of the first actuator 350a and the second actuator 350b. Mounting or attachment can be achieved via snap-fit ​​connection, interference fit (e.g., friction fit) connection, adhesive, or other suitable coupling techniques. The top 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 pointed tip. For example, each of the first blade 348a and the second blade 348b may have two pointed tips with a concave edge between them and a curved edge adjacent to each tip. 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) that has been cut or otherwise shaped to have the desired profile and bent to its final form. In another case, the first blade 348a and the second blade 348b may be formed from plastic.

[0114] Based on the plan view, the dimensions and shapes of the portions where the first blade 348a, the second blade 348b, the first actuator 350a, and the second actuator 350b are mounted can correspond to the dimensions and shapes of the storage outlet in the insert 342. Furthermore, as... Figure 26 As shown, the first actuator 350a and the second actuator 350b may include: protruding edges (e.g., curved inner lips facing each other) configured to push two pierced sections of the seal 344 into the reservoir when the first blade 348a and the second blade 348b enter 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, two valves (from the two pierced sections of the seal 344, such as...) open. Figure 24 (As shown) can 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 actuator 350a and the second actuator 350b. As a result, the possibility of the two puncture openings in the seal 344 (due to the two valves of the two puncture sections) becoming blocked can be reduced or prevented. Furthermore, the first actuator 350a and the second actuator 350b can be configured to guide a non-nicotine vapor precursor formulation from the reservoir to the absorbent material 346.

[0115] 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.

[0116] Figure 27 yes Figure 22 A perspective view of the connector module, which does not have a liquid-absorbing core, heater, electrical leads, and contact core. Figure 28 yes Figure 27 An exploded view of the connector module. See also... Figures 27 to 28 The module housing 354 and the panel 366 typically form the outer frame of the connector module 320. The module housing 354 defines a first module inlet 330 and a recessed edge 356. The recessed edge 356 of the module housing 354 exposes a second module inlet 332 (defined by a bypass structure 358). However, it should be understood that the recessed edge 356 can also be considered as defining a module inlet (e.g., in combination with the panel 366). The panel 366 has a recessed edge 328 that, together with the corresponding side surface of the cavity 310 of the second housing segment 308, defines a pod inlet 322. Furthermore, the panel 366 defines a first contact opening, a second contact opening, and a third contact opening. The first and second contact openings may be square and configured to expose a first power contact 324a and a second power contact 324b, respectively, while the third contact opening may be rectangular and configured to expose a plurality of data contacts 326, but the exemplary embodiments are not limited thereto.

[0117] The first power contact 324a, the second power contact 324b, the printed circuit board (PCB) 362, and the bypass structure 358 are disposed within an external frame formed by the module housing 354 and the panel 366. The printed circuit board (PCB) 362 includes a plurality of data contacts 326 on its upstream side (in Figure 28 (The sensor 364 is hidden from view in the middle) and on its downstream side. The bypass structure 358 defines the second module inlet 332 and the bypass outlet 360.

[0118] During assembly, the first power contact 324a and the second power contact 324b are positioned so that they are visible through the first contact opening and the second contact opening of the panel 366, respectively. Furthermore, the printed circuit board (PCB) 362 is positioned such that a plurality of data contacts 326 on its upstream side are visible through the third contact opening of the panel 366. The PCB 362 may also overlap with the rear surfaces of the first power contact 324a and the second power contact 324b. A bypass structure 358 is positioned on the PCB 362 such that the sensor 364 is located within the airflow path defined by the second module inlet 332 and the bypass outlet 360. During assembly, the bypass structure 358 and the PCB 362 can be considered to be surrounded on at least four sides by the tortuous structure of the first power contact 324a and the second power contact 324b. In an exemplary embodiment, the bifurcated ends of the first power contact 324a and the second power contact 324b are configured to be electrically connected to the first electrical lead 340a and the second electrical lead 340b.

[0119] When air enters through the pod inlet 322 during suction, the first module inlet 330 may receive the main stream (e.g., a larger flow) of the incoming air, while the second module inlet 332 may receive a secondary stream (e.g., a smaller flow). The secondary stream of incoming air can improve the sensitivity of the sensor 364. After exiting the bypass structure 358 through the bypass outlet 360, the secondary stream re-converges with the main stream to form a combined flow that is drawn in and passes through the contact core 334 to encounter the heater 336 and the suction core 338. In a non-limiting embodiment, the main stream may be 60-95% (e.g., 80-90%) of the incoming air, while the secondary stream may be 5-40% (e.g., 10-20%) of the incoming air. However, it should be understood that other ranges may be used, which may be higher or lower than those disclosed above.

[0120] The first module inlet 330 can be a blocking inhalation (RTD) port, while the second module inlet 332 can be a bypass port. In this configuration, the inhalation resistance for the non-nicotine electronic cigarette device 500 can be adjusted by changing the size of the first module inlet 330 (rather than changing the size of the pod inlet 322). In an exemplary embodiment, the size of the first module inlet 330 can be selected such that the inhalation resistance is between 25 and 100 mmH2O (e.g., between 30 and 50 mmH2O). For example, a diameter of 1.0 mm for the first module inlet 330 can result in an inhalation resistance of 88.3 mmH2O. In another case, a diameter of 1.1 mm for the first module inlet 330 can result in an inhalation resistance of 73.6 mmH2O. In yet another case, a diameter of 1.2 mm for the first module inlet 330 can result in an inhalation resistance of 58.7 mmH2O. In yet another case, a diameter of 1.3 mm for the first module inlet 330 can result in an inhalation resistance of approximately 40-43 mmH2O. It is worth noting that, due to its internal layout, the size of the first module inlet 330 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. Other aspects of 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 / 696,081 entitled “Non-nicotine pod Assemblies And Non-nicotine E-vaping Devices” (Atty.Dkt.No.24000NV-000623-US), the entire contents of which are incorporated herein by reference.

[0121] 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.

[0122] 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 (particularly in the range of approximately 175°F or higher) at relatively low pressures (e.g., 1 atmosphere), non-nicotine compounds may undergo a significantly increased decarboxylation process (e.g., 50% or higher). Temperatures of approximately 240°F or higher can result in rapid or transient decarboxylation at relatively high decarboxylation rates, but further increases in temperature can lead to impairment of some or all of the chemical properties of the non-nicotine compound.

[0123] In an exemplary embodiment, the non-nicotine compound may be derived from medicinal plants (e.g., natural components of plants that provide medically acceptable therapeutic effects).

[0124] 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 ACOMPOUND USING THE SAME,” the disclosure of which is incorporated herein by reference in its entirety.

[0125] 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, the 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.

[0126] 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.
