[0020] FIG. 1 is a front view of a non-nicotine e-vaping device according to one embodiment. FIG. 2 is a side view of the non-nicotine e-vaping device of FIG. 1. FIG. 3 is a rear view of the non-nicotine e-vaping device of FIG. 1. With reference to FIG. 1 through 3, the non-nicotine e-vaping device (500) comprises a device body (100) configured to accommodate a non-nicotine pod assembly (300). The non-nicotine pod assembly (300) is a modular entity configured to store a non-nicotine pre-vapor formulation. The non-nicotine pre-vapor formulation is a substance or combination of substances that is nicotine-free and can be converted into non-nicotine vapor. For example, the non-nicotine pre-vapor formulation may include liquid, solid, and / or gel formulations. For example, solutions and suspensions containing water (e.g., emulsifiers), oils, beads, solvents, active ingredients, ethanol, plant extracts, nicotine-free compounds, natural or artificial flavors, vapor formers such as glycerin and propylene glycol, and / or other ingredients suitable for smoking, which are not limited thereto. During smoking, the nicotine-free electronic smoking device (500) is configured to heat a nicotine-free vapor-preparation to produce nicotine-free vapor. Nicotine-free vapor, nicotine-free aerosol, and nicotine-free dispersion are used interchangeably and refer to a substance produced or output by a nicotine-free (nicotine-free) initiator or claimed device and / or its equivalent.

[0021] As shown in FIGS. 1 and 3, the nicotine-free electronic smoking device (500) is extended in the longitudinal direction and has a length greater than its width. Also, as shown in FIG. 2, the length of the nicotine-free electronic smoking device (500) is also greater than its thickness. Additionally, the width of the nicotine-free electronic smoking device (500) may be greater than its thickness. Assuming an xyz Cartesian coordinate system, the length of the nicotine-free electronic smoking device (500) may be measured in the y direction, the width in the x direction, and the thickness in the z direction. The nicotine-free electronic smoking device (500) may have a substantially linear shape that tapers and / or is rounded depending on the front, side, and rear views, but embodiments are not limited thereto.

[0022] The device body (100) includes a front cover (104), a frame (106), and a rear cover (108). The front cover (104), the frame (106), and the rear cover (108) form a device housing that encloses mechanical components, electronic components, and / or circuits related to the operation of the nicotine-free electronic smoking device (500). For example, the device housing of the device body (100) may enclose a power source configured to power the nicotine-free electronic smoking device (500), which may include supplying current to the nicotine-free pod assembly (300). Additionally, when assembled, the front cover (104), the frame (106), and the rear cover (108) may constitute most of the visible portion of the device body (100). The device housing may be considered to include all components of the device body (100), except for the mouthpiece (102). In other words, the mouthpiece (102) and the device housing can be considered to form the device body (100).

[0023] The front cover (104) (e.g., the first cover) defines a primary opening configured to accommodate a bezel structure (112). The primary opening may have a rounded rectangular shape, but other shapes may also be possible depending on the shape of the bezel structure (112). The bezel structure (112) defines a through hole (150) configured to accommodate a nicotine-free pod assembly (300). The through hole (150) is discussed in more detail here, for example, in relation to FIG. 7.

[0024] The front cover (104) also defines a secondary opening configured to accommodate a light guide arrangement. The secondary opening may resemble a slot, but may have a different shape depending on the shape of the light guide arrangement. In an exemplary embodiment, the light guide arrangement includes a guide housing (114) and a button housing (122). The light guide housing (114) is configured to expose a light guide lens (116). The button housing (122) may have an upstream portion configured as a first button (118) and a downstream portion configured as a second button (120). The button housing (122) may be in the form of a single structure or two separate structures. In the case of two separate structures, the first button (118) and the second button (120) may move with a more independent feel when pressed.

[0025] The operation of the nicotine-free electronic smoking 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. It should be understood that although two buttons are shown in the drawing in relation to the light guide device, more (or fewer) buttons may be provided depending on the available functions and the desired user interface.

[0026] A frame (106) (e.g., a base frame) is a central support structure of the device body (100) (and the entirety of the nicotine-free electronic smoking device (500)). The frame (106) may be referred to as a chassis. The frame (106) includes a proximal end, a distal end, and a pair of lateral sections between the proximal and distal ends. The proximal and distal ends may also be referred to as a downstream end and an upstream end, respectively. As used herein, "proximal" (and conversely "distal") is related to an adult smoker in the act of smoking, and "downstream" (and conversely "upstream") is related to the flow of nicotine-free vapor. For additional durability and stability, a bridging section may be provided between the opposing inner surfaces of the lateral sections (e.g., about halfway along the length of the frame (106)). The frame (106) can be formed integrally to form a monolithic structure.

[0027] Regarding the compositional material, the frame (106) may be formed from an alloy or plastic. The alloy (e.g., die-cast grade, machinable grade) may be an aluminum (Al) alloy or a zinc (Zn) alloy. The plastic may be polycarbonate (PC), acrylonitrile butadiene styrene (ABS), or a combination thereof (PC / ABS). For example, the polycarbonate may be LUPOY SC1004A. Additionally, the frame (106) may be provided with a surface finish for functional and / or aesthetic reasons (e.g., to provide a luxurious appearance). In one embodiment, the frame (106) (e.g., when formed from an aluminum alloy) may be anodized. In another embodiment, the frame (106) (e.g., when formed from a zinc alloy) may be coated with hard enamel or painted. In yet another embodiment, the frame (106) (e.g., when formed from a polycarbonate) may be metallized. In another embodiment, the frame (106) (e.g., when formed of acrylonitrile butadiene styrene) may be electroplated. It should be understood that the constituent material associated with the frame (106) may also be applied to the front cover (104), the rear cover (108), and / or other suitable parts of the nicotine-free electronic smoking device (500).

[0028] The rear cover (108) (e.g., a second cover) also defines an opening configured to accommodate the bezel structure (112). The opening may have a rounded rectangular shape, but other shapes may also be possible depending on the shape of the bezel structure (112). In one embodiment, the opening of the rear cover (108) is smaller than the main opening of the front cover (104). It should also be understood that, although not shown, a light guide device (e.g., including buttons) may be provided on the rear of the nicotine-free electronic smoking device (500) in addition to (or instead of) the light guide device on the front of the nicotine-free electronic smoking device (500).

[0029] The front cover (104) and the rear cover (108) may be configured to be fastened to the frame (106) via a snap-fit ​​structure. For example, the front cover (104) and / or the rear cover (108) may include clips configured to interlock with a corresponding mating member of the frame (106). In a non-limiting embodiment, the clips may be in the form of tabs having orifices configured to receive a corresponding mating member of the frame (106) (e.g., a protrusion having a bezel edge). Alternatively, the front cover (104) and / or the rear cover (108) may be configured to be fastened to the frame (106) via an interference fit (also referred to as a press fit or friction fit). However, the front cover (104), the frame (106), and the rear cover (108) may be joined via other suitable methods and techniques.

[0030] The device body (100) also includes a mouthpiece (102). The mouthpiece (102) can be secured to the proximal end of the frame (106). Also, as shown in FIG. 2, in one embodiment where the frame (106) is sandwiched between the front cover (104) and the rear cover (108), the mouthpiece (102) can be abut the front cover (104), the frame (106), and the rear cover (108). Additionally, in one embodiment that is not limited, the mouthpiece (102) can be coupled to the device housing via a bayonet connection.

[0031] FIG. 4 is a drawing of the proximal end of the nicotine-free electronic smoking device of FIG. 1. Referring to FIG. 4, the outlet face of the mouthpiece (102) defines a plurality of vapor outlets. In one embodiment, which is not limited, the outlet face of the mouthpiece (102) may be elliptical. Additionally, the outlet face of the mouthpiece (102) may include a first crossbar corresponding to the major axis of the elliptical outlet face and a second crossbar corresponding to the minor axis of the elliptical outlet face. Furthermore, the first crossbar and the second crossbar may intersect perpendicularly and may be a part formed integrally of the mouthpiece (102). It should be understood that although the outlet face is depicted as defining four vapor outlets, one embodiment is not limited thereto. For example, the outlet surface can define fewer than 4 steam outlets (e.g., 1, 2) or more than 4 steam outlets (e.g., 6, 8).

[0032] FIG. 5 is a diagram of the distal end of the nicotine-free electronic smoking device of FIG. 1. Referring to FIG. 5, the distal end of the nicotine-free electronic smoking device (500) includes a port (110). The port (110) is configured to receive current from an external power source (e.g., via a USB / mini USB cable) to charge the internal power within the nicotine-free electronic smoking device (500). Additionally, the port (110) may be configured to transmit and / or receive data to and from another nicotine-free electronic smoking device or other electronic device (e.g., a phone, tablet, or computer). Additionally, the nicotine-free electronic smoking device (500) may be configured to communicate wirelessly with other electronic devices, such as a phone, through application software (app) installed on the electronic device. In this case, an adult smoker may control the nicotine-free electronic smoking device (500) (e.g., checking the location and usage information of the nicotine-free electronic smoking device, changing operating parameters) or otherwise interface with it through the app.

[0033] FIG. 6 is a perspective view of the nicotine-free electronic smoking device of FIG. 1. With reference to FIG. 6, as briefly mentioned above, the nicotine-free electronic smoking device (500) comprises a nicotine-free pod (300) that stores a nicotine-free vapor-free preparation. The nicotine-free pod assembly (300) has an upstream end (a side facing the light guide device) and a downstream end (a side facing the mouthpiece (102)). In one embodiment that is not limited, the upstream end is the opposite surface of the nicotine-free pod assembly (300) from the downstream end. The upstream end of the nicotine-free pod assembly (300) may define at least one upstream recess (e.g., the first upstream recess (312a) and / or the second upstream recess (312b) of FIG. 14), and the downstream end of the nicotine-free pod assembly (300) may define at least one downstream recess (e.g., the first downstream recess (306a) and / or the second downstream recess (306b) of FIG. 15). As discussed in more detail herein, the bezel structure (112) of the device body (100) is connected to the upstream end (e.g., through at least one upstream recess) and downstream end (e.g., through at least one downstream recess) of the nicotine-free pod assembly (300) when the nicotine-free pod assembly (300) is seated within the device body (100).

[0034] The device body (100) and the nicotine-free pod assembly (300) include mechanical components, electronic components and / or circuits associated with the operation of the nicotine-free electronic smoking device (500), which are described in more detail in this document and / or incorporated by reference in this document. For example, the nicotine-free pod assembly (300) may include mechanical components configured to operate to release a nicotine vapor-free preparation from a sealed reservoir. The nicotine-free pod assembly (300) may also have a mechanical structure (aspect) configured to engage with the device body (100) to facilitate the insertion and seating of the nicotine-free pod assembly (300).

[0035] Additionally, the nicotine-free pod assembly (300) may be a "smart pod" comprising electronic components and / or circuits configured to store, receive, and / or transmit information to / from the device body (100). This information may be used to authenticate the nicotine-free pod assembly (300) for use with the device body (100) (e.g., to prevent the use of unauthorized / counterfeit nicotine-free pod assemblies). This information may also be used to identify the type of the nicotine-free pod assembly (300) and is related to a vaping profile based on the identified type. The vaping profile may be designed to set general parameters for heating the nicotine-free vapor-preparation and may be subject to adjustment, improvement, or other adjustment for an adult smoker before and / or during smoking.

[0036] The nicotine-free pod assembly (300) may also communicate other information that may be related to the operation of the nicotine-free electronic smoking device (500) with the device body (100). Examples of relevant information may include the level of nicotine-free vapor-free preparation within the nicotine-free pod assembly (300) and / or the time elapsed since the nicotine-free pod assembly (300) was inserted into the device body (100) and activated. For example, if the nicotine-free pod assembly (300) has been inserted into the device body (100) and activated for a certain period of time (e.g., 6 months or more), the nicotine-free electronic smoking device (500) may not allow smoking, and the adult smoker may be induced to switch to a new nicotine-free pod assembly, even if the nicotine-free pod assembly (300) still contains an appropriate level of nicotine-free vapor-free preparation.

[0037] As mentioned above and as will be discussed in detail here, the device body (100) may include mechanical components (e.g., supplementary structures) configured to secure, fasten, and / or activate the nicotine-free pod assembly (300). Additionally, the device body (100) may include electronic components and / or circuits configured to receive current to charge an internal power source (e.g., battery), which is configured to power the nicotine-free pod assembly (300) during smoking. Additionally, the device body (100) may include electronic components and / or circuits configured to communicate with the nicotine-free pod assembly (300), other nicotine-free electronic power sources, other electronic devices (e.g., telephones, tablets, computers), and / or adult smokers. The information communicated may include pod-specific data, current smoking details, and / or past smoking patterns / history. For adult smokers, communication with tactile (e.g., vibration), auditory (e.g., beeping) and / or visual (e.g., color / blinking light) feedback may be notified. Requests for information and / or communication may be made via a port (110) (e.g., via a USB / mini-USB cable).

[0038] FIG. 7 is a perspective view of the device body of the nicotine-free electronic smoking device of FIG. 6. FIG. 8 is an enlarged view of the bezel structure of FIG. 7. FIG. 9 is another enlarged view of the bezel structure of FIG. 7. Referring to FIG. 7 through 9, the device body (100) defines a through hole (150) configured to accommodate a nicotine-free pod assembly (300). In an exemplary embodiment, the bezel structure (112) of the device body (100) defines the through hole. The through hole (150) may have a rectangular shape with rounded corners, but other shapes are also possible depending on the configuration of the nicotine-free pod assembly (300). The bezel structure (112) may be integrally formed to be a monolithic elastic article having at least one flexible part (e.g., an upstream panel and / or a downstream panel with a protrusion) configured to engage (interlock) with the nicotine-free pod assembly (300) when the nicotine-free pod assembly (300) is seated within the through hole (150). For example, the bezel structure (112) may be formed of plastic. Thus, the nicotine-free pod assembly (300) can be positioned relatively easily and held firmly within the device body (100) in a cost-effective manner.

[0039] The bezel structure (112) has a length, width, and depth. The length of the bezel structure (112) is in the longitudinal direction (vertical direction) of the device body (100), the width of the bezel structure (112) is in the longitudinal direction of the device body (100), and the width of the bezel structure (112) is in the transverse direction across the through hole (150) and perpendicular to the longitudinal direction of the device body (100). The depth of the bezel structure (112) is in the vertical direction passing through the through hole (150) and may be perpendicular to both the longitudinal direction of the device body (100) and the transverse direction across the through hole (150). For example, assuming an xyz orthogonal coordinate system, the length of the bezel structure (112) may be measured in the y-direction, the width may be measured in the x-direction, and the depth may be measured in the z-direction. The length of the bezel structure (112) is greater than the width, and the width of the bezel structure (112) may be greater than the depth.

[0040] As illustrated in FIG. 8, the bezel structure (112) may include a first downstream corner defining a first downstream slit (154a) and a second downstream corner defining a second downstream slit (154b). Additionally, as illustrated in FIG. 9, the bezel structure (112) may include a first upstream corner defining a first upstream slit (152a) and a second upstream corner defining a second upstream slit (152b). Consequently, in an exemplary embodiment where the bezel structure (112) has an upstream sidewall, an opposing downstream sidewall, and a pair of sidewalls between them to define a through hole (150), at least the upstream sidewall and / or downstream sidewall may be configured to be deflected (by the slits) during insertion of the nicotine-free pod assembly (300). For example, the upstream and downstream sidewalls of the bezel structure (112) may be flexed to move away from each other during the insertion of the non-nicotine pod assembly (300). Accordingly, the upstream and downstream sidewalls of the bezel structure (112) may be resilient sections configured to transition (e.g., reversibly) from a nonloaded state to a loaded state when the non-nicotine pod assembly (300) is received in the device body (100).

[0041] As illustrated in FIG. 8, the downstream sidewall portion between the first downstream slit (154a) and the second downstream slit (154b) may be a downstream engagement panel (158). Similarly, as illustrated in FIG. 9, the upstream sidewall portion between the first upstream slit (152a) and the second upstream slit (152b) may be an upstream engagement panel (156). Each of the first upstream slit (152a) and the second upstream slit (152b), the first downstream slit (154a) and the second downstream slit (154b) may have at least 30 percent (e.g., at least 40 percent) of the depth (e.g., average depth) of the bezel structure (112) in the longest dimension (e.g., in the depth direction of the bezel structure (112)), but other dimensions are also possible as long as the configuration allows for resilient lever-like action by the upstream fastening panel (156) and the downstream fastening panel (158).

[0042] The upstream sidewall and / or downstream sidewall of the bezel structure (112) may include at least one protrusion (e.g., a detent) configured to hold the nicotine-free pod assembly (300) within the device body (100) (e.g., through a through hole (150) of the device body (100) (through engagement with one or more recesses of the nicotine-free pod assembly (300)). For example, as shown in FIG. 8, the downstream engagement panel (158) of the downstream sidewall may include a first downstream protrusion (130a) and a second downstream protrusion (130b). The first downstream protrusion (130a) may be adjacent to the first downstream slit (154a) and the rear of the device body (100) (e.g., a rear cover (108)), and the second downstream protrusion (130b) may be adjacent to the second downstream slit (154b). and may be adjacent to the rear of the device body (100) (e.g., rear cover (108)). Similarly, as illustrated in FIG. 9, the upstream fastening panel (156) of the upstream sidewall may include a first upstream protrusion (128a) and a second upstream protrusion (128b). The first upstream protrusion (128a) may be adjacent to the first upstream slit (152a) and the rear of the device body (100) (e.g., rear cover (108)), while the second upstream protrusion (128b) may be adjacent to the second upstream slit (152b) and the rear of the device body (100) (e.g., rear cover (108)).

[0043] Although a pair of protrusions are illustrated in relation to the upstream and downstream sidewalls of the bezel structure (112), it should be understood that other numbers may be suitable (e.g., one protrusion each, or three protrusions each). Additionally, in an exemplary embodiment, each protrusion may be in the form of a spherical cap (e.g., a hemisphere). Alternatively, one or more of the protrusions may be in the form of an elliptical cap (e.g., a semi-elliptical), a ridge (e.g., circular, oblique), or other suitable mating structure for engaging with a corresponding recess of the nicotine-free pod assembly (300). Additionally, the protrusion(s) may be a part formed integrally with the bezel structure (112).

[0044] The first upstream protrusion (128a) and the second upstream protrusion (128b) are urged by the upstream fastening panel (156) of the upstream sidewall (e.g., from an unloaded state) to engage with the corresponding upstream recess of the nicotine-free pod assembly (300) during a loaded state. Similarly, the first downstream protrusion (130a) and the second downstream protrusion (130b) are urged by the downstream fastening panel (158) of the downstream sidewall (e.g., from an unloaded state) to engage with the corresponding downstream recess of the nicotine-free pod assembly (300) during a loaded state. Accordingly, in an exemplary embodiment, when the nicotine-free pod assembly (300) is seated within the through hole (150) of the device body (100), the nicotine-free pod assembly (300) is secured between the upstream fastening panel (156) of the upstream sidewall and the downstream fastening panel (158) of the downstream sidewall.

[0045] When the nicotine-free pod assembly (300) is inserted into the through hole (150) of the device body (100), the upstream protrusion pair (e.g., the first upstream protrusion (128a) and the second upstream protrusion (128b)) of the bezel structure (112) may be connected to the corresponding upstream concave pair of the nicotine-free pod assembly (300) before the downstream protrusion pair (e.g., the first downstream protrusion (130a) and the second downstream protrusion (130b)) of the bezel structure (112) is connected to the corresponding downstream concave pair of the nicotine-free pod assembly (300) (or vice versa). In another example, the upstream pair of protrusions and the downstream pair of protrusions of the bezel structure (112) may be joined substantially simultaneously with the corresponding upstream pair of recesses and the downstream pair of recesses of the nicotine-free pod assembly (300) when the nicotine-free pod assembly (300) is inserted into the through hole (150) of the device body (100). Additionally, the joining of the corresponding recesses of the nicotine-free pod assembly (300) and the protrusions of the bezel structure (112) may generate auditory feedback (e.g., an auditory click sound) and / or haptic feedback (e.g., vibration) to inform an adult smoker that the nicotine-free pod assembly (300) is correctly mounted in the through hole (150) of the device body (100).

[0046] The downstream sidewall of the bezel structure (112) may define a downstream opening (e.g., the downstream opening (148) of FIG. 11). As a result, as in the exemplary embodiment shown in FIG. 7 and 8, the distal end of the mouthpiece (102) extends into the through hole (150) through the downstream opening of the bezel structure (112) (e.g., between the first downstream slit (154a) and the second downstream slit (154b)). The distal end of the mouthpiece (102) may be in the form of an annular elastic structure. Due to its elastic properties, the distal end of the mouthpiece (102) may be temporarily deformed to accommodate the insertion of a non-nicotine pod assembly (300) into the through hole (150) of the device body (100). Additionally, the elasticity of the distal end of the mouthpiece (102) can help establish a vapor-tight seal with the pod outlet of the non-nicotine pod assembly (300).

[0047] The device electrical contacts of the device body (100) are configured to engage with the pod electrical contacts of the nicotine-free pod assembly (300) when the nicotine-free pod assembly (300) is seated within the through hole (150) of the device body (100). The device electrical contacts of the device body (100) include a device electrical connector (132). As illustrated in FIG. 9, the device electrical connector (132) of the device body (100) is positioned upstream of the through hole (150). The device electrical connector (132) of the device body (100) is positioned upstream of the through hole (150). The device electrical connector (132) of the device body (100) is configured to be electrically connected to the nicotine-free pod assembly (300) mounted within the through hole (150). Therefore, power can be supplied from the device body (100) to the nicotine-free pod assembly (300) through the device electric connector (132) during smoking. Additionally, data can be transmitted to and / or received from the device body (100) and the nicotine-free pod assembly (300) through the device electric connector (132).

[0048] The device electrical connector (132) includes power contacts and data contacts. The power contacts of the device electrical connector (132) are configured to supply power from the device body (100) to the nicotine-free pod assembly (300). As illustrated, the power contacts of the device electrical connector (132) include a first power contact and a second power contact, which may be positioned closer to the rear cover (108) than to the front cover (104) or vice versa. The first power contact may be adjacent to the first upstream protrusion (128a), and the second power contact may be adjacent to the second upstream protrusion (128b). The first power contact and the second power contact of the device electrical connector (132) are tractably mounted and biased so as to protrude into the through hole (150) and may be retracted (pushed out) from the through hole (150) (e.g., independently) when subjected to a force that overcomes the bias.

[0049] The data contacts of the device electric connector (132) are configured to transmit data between the nicotine-free pod assembly (300) and the device body (100). As illustrated, the data contacts of the device electric connector (132) include six protrusions arranged in a row, but exemplary embodiments are not limited thereto. The data contacts of the device electric connector (132) may be positioned closer to the front cover (104) than to the rear cover (108) (or vice versa). The data contacts of the device electric connector (132) may be individual structures that extend into the through hole (150) upon assembly. The data contacts of the device electric connector (132) may be mounted and deflected to protrude into the through hole (150) in a manner that is easy to handle, and may be pushed out of the through hole (150) (e.g., independently) when subjected to a force that overcomes the deflection.

[0050] For example, when a non-nicotine pod assembly (300) is inserted into a through hole (150) of a device body (100), the pod electrical contact of the non-nicotine pod assembly (300) presses against the corresponding device electrical contact of the device body (100). As a result, the power contact and data contact of the device electrical connector (132) are pushed into the device body (100) (e.g., at least partially pushed in), but due to the elastic structure, they still push against the corresponding pod electrical contact, ensuring a proper electrical connection between the device body (100) and the non-nicotine pod assembly (200). Furthermore, this connection can be mechanically secure and minimize contact resistance so that power and / or signals can be reliably and accurately transmitted and / or communicated between the device body (100) and the non-nicotine pod assembly (300). While various structures regarding the device electrical contact of the device body (100) have been discussed, it should be understood that one embodiment is not limited thereto and other configurations may be used.

[0051] FIG. 10 is a partially exploded view including the mouthpiece of FIG. 9. Referring to FIG. 10, the mouthpiece (102) is configured to extend through the frame (106) of the device housing and to be connected to the bezel structure (112). As described in more detail herein, the mouthpiece (102) is an assembly of several individual parts. Alternatively, the mouthpiece (102) may be a structure formed integrally. In an exemplary embodiment, the proximal ends of the frame (106) and the bezel structure (112) are configured to receive the distal end of the mouthpiece (102). As illustrated, each proximal end of the frame (106) and the bezel structure (112) may be a female end, and the distal end of the mouthpiece may be a male end.

[0052] For example, the mouthpiece (102) may be fixed, mate, or coupled (e.g., reversibly coupled) to the bezel structure (112) via an insertable connection. In this case, the female end of the bezel structure (112) may define a pair of opposing L-shaped slots, while the male end of the mouthpiece (102) may have opposing radial members (134) (e.g., radial pins) configured to engage with the L-shaped slots of the bezel structure (112). Each of the L-shaped slots of the bezel structure (112) may have a longitudinal portion and a circumferential portion. Optionally, the terminus of the circumferential portion may have a serif to reduce or prevent the radial member (134) of the mouthpiece (102) from being accidentally released.

[0053] In one embodiment without limitation, the longitudinal portions of the L-shaped slots extend parallel to the longitudinal axis of the device body (100), while the circumferential portions of the L-shaped slots extend around the longitudinal axis (e.g., the center axis) of the device body (100). As a result, to attach the mouthpiece (102) to the device housing, (e.g., based on the drawing illustrated in FIG. 10) the mouthpiece (102) is first rotated 90 degrees to align the radial member (134) with the downstream opening of the proximal end of the frame (106) and the entrance to the longitudinal portion of the L-shaped slot of the bezel structure (112). Then, the mouthpiece (102) is inserted through the frame (106) into the bezel structure (112), and the radial member (134) slides along the longitudinal portion of the L-shaped slot until it reaches a junction with each circumferential portion. At this time, the mouthpiece (102) is rotated so that the radial member (134) moves along the circumferential portions until it reaches each end. If there is an anti-release portion at each end, tactile and / or auditory feedback (e.g., an auditory click) can be generated to inform an adult smoker that the mouthpiece (102) is properly coupled to the device housing. A pair of radial members (134) and a corresponding pair of L-shaped slots are discussed here, but it should be understood that in some cases, a single radial member (134) and a single corresponding L-shaped slot are appropriate.

[0054] The mouthpiece (102) defines a vapor passage (136) through which nicotine-free vapor flows during smoking. The vapor passage (136) is in fluid communication with a through hole (150) (where the nicotine-free pod assembly (300) is mounted within the device body (100). The proximal end of the vapor passage (136) may include a flared portion. Additionally, the mouthpiece (102) may include a distal cover (138). The distal cover (138) may narrow from the distal end to the proximal end. The outlet surface of the distal cover (138) defines a plurality of vapor outlets. Although four vapor outlets are shown on the distal cover (138), it should be understood that one embodiment is not limited thereto.

[0055] FIG. 11 is a partially exploded view relating to the bezel structure of FIG. 9. FIG. 12 is an enlarged perspective view of the mouthpiece, fixing structure, and bezel structure of FIG. 11. Referring to FIG. 11 and FIG. 12, the bezel structure (112) includes an upstream sidewall and a downstream sidewall. A connector opening (146) is defined in the upstream sidewall of the bezel structure (112). 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 bezel structure (112) defines a downstream opening (148). The downstream opening (148) of the bezel structure (112) is configured to receive the distal end of the mouthpiece (102).

[0056] To facilitate attachment to the device housing, the bezel structure (112) has an upstream pair of tabs and a downstream pair of tabs (e.g., external tabs). The upstream pair of tabs may be adjacent to the connector opening (146) (e.g., one tab on each side of the connector opening (146)), while the downstream pair of tabs may be adjacent to the downstream opening (148) (e.g., one tab on each side of the downstream opening (148)). Similarly, the frame (106) of the device housing has an upstream pair of tabs and a downstream pair of tabs (e.g., internal tabs) corresponding to the upstream pair of tabs and the downstream pair of tabs of the bezel structure (112), respectively. The bezel structure (112) may be secured to the frame (106) of the device housing through the tabs using at least a retention structure (140).

[0057] The fixed structure (140) may include a first fastener (142a), a second fastener (142b), and a catch mechanism (e.g., as an intermediate connecting member). In an exemplary embodiment, the first fastener (142a) and the second fastener (142b) may be individual parts (e.g., screws) extending through holes at two opposite ends of the catch mechanism. A downstream tab pair of the bezel structure (112) may be secured to a corresponding downstream tab pair of the frame (106) using the first fastener (142a) and the second fastener (142b) of the fixed structure (140). Likewise, as specifically illustrated in FIG. 11, an upstream tab pair of the bezel structure (112) may be secured to a corresponding upstream tab pair of the frame (106) using an upstream fastener similar or identical to the first fastener (142a) and the second fastener (142b).

[0058] As illustrated in FIG. 12, the female end of the proximal end of the bezel structure (112) may be a cylindrical section defining a downstream opening (148) as well as a pair of opposing L-shaped slots for establishing a bayonet connection with the opposing radial members (134) of the mouthpiece (102). In an exemplary embodiment, one of the circumferential portions of the L-shaped slots may be an open portion of the cylindrical section (e.g., an open portion on the underside of the cylindrical section with reference to FIG. 12). In this example, when a pair of downstream tabs of the bezel structure (112) is secured to a corresponding pair of downstream tabs of the frame (106) by a fixing structure (140), a retaining mechanism (connecting the first fastener (142a) and the second fastener (142b)) will be aligned with an open portion of a cylindrical section to define at least a portion of the circumferential portion of one of the L-shaped slots. The retaining mechanism of the fixing structure (140) includes two angled fingers separated by a gap approximately corresponding to the width of one of the radial members (134) of the mouthpiece (102). The two angled fingers of the retaining mechanism are elastic and flex when the mouthpiece (102) rotates (e.g., during assembly) to accommodate circumferential movement of a corresponding radial member (134). When the corresponding radial member (134) reaches the gap between the two angled fingers of the retaining mechanism, the bent angled fingers will rebound or spring back in an unloaded state to seat (e.g., hold) the radial member (134) within the gap. In the seated state, the two angled fingers of the retaining mechanism may contact or be adjacent to the sides of the corresponding radial member (134) to resist further rotation of the mouthpiece (102).As a result, the insertable connection between the mouthpiece (102) and the bezel structure (112) can be maintained in a relatively safe manner by the fixed structure (140).

[0059] During assembly, the bezel structure (112) may be fixed to the frame (106) (along with other mechanical components, electronic components, and / or circuits) before the front cover (104) and the rear cover (108) are attached to the frame (106). For example, the bezel structure (112) may be initially positioned relative to the frame (106) so that the downstream tabs and upstream tabs of the bezel structure (112) are aligned with the downstream tabs and upstream tabs of the frame (106), respectively. In an exemplary embodiment where each tab has an orifice (e.g., a pre-formed orifice) extending through it, the orifice of the downstream tab and the orifice of the upstream tab may consequently be aligned and positioned. Once proper alignment is achieved, the first fastener (142a) and the second fastener (142b) can be introduced through the downstream tab of the frame (106) and then through the downstream tab of the bezel structure (112) (e.g., through the bottom surface of the tab in the drawing of FIG. 11). Similarly, the upstream fastener can be introduced in a similar manner through the upstream tab of the frame (106) and then through the upstream tab of the bezel structure (112). Although FIG. 11 shows a device housing already assembled before the attachment of the bezel structure (112), it should be understood that this partial exploded view is intended only to show specific parts (e.g., the bezel structure (112)) separately from other parts of the device body (100), and therefore does not necessarily indicate the order of assembly of the device body (100).

[0060] FIG. 13 is a partially exploded view including the front cover, frame, and rear cover of FIG. 11. Referring to FIG. 13, various mechanical components, electronic components, and / or circuits related to the operation of the nicotine-free electronic smoking device (500) can be secured to the frame (106). The front cover (104) and rear cover (108) can be configured to be fastened to the frame (106) via a snap fit. In one embodiment, the front cover (104) and rear cover (108) include clips configured to be fastened to corresponding mating members of the frame (106). The clips may be in the form of tabs having orifices configured to receive corresponding joining members of the frame (106) (e.g., a protrusion having a bezel edge). The front cover (104) has two rows, each with four clips (a total of eight clips for the front cover (104)). Likewise, the rear cover (108) has two rows, each with four clips (a total of eight clips for the rear cover (108)). The corresponding mating member of the frame (106) may be located on the inner side wall of the frame (106). Thus, when the front cover (104) and the rear cover (108) are joined, the joined clips and mating member may be hidden from view. Alternatively, the front cover (104) and / or the rear cover (108) may be configured to be joined to the frame (106) through an interference fit. However, the front cover (104), the frame (106), and the rear cover (108) may be joined through other suitable methods and techniques.

[0061] FIG. 14 is a perspective view showing a nicotine-free pod assembly of a nicotine-free electronic smoking device of FIG. 6. FIG. 15 is another perspective view of the nicotine-free pod assembly of FIG. 14. Referring from FIG. 14 to FIG. 15, the nicotine-free pod assembly (300) of a nicotine-free electronic smoking device (500) includes a front face, a rear face opposite the front face, a first side face between the front and the rear face, a second side face opposite the first side face, an upstream end face, and a downstream end face opposite the upstream end face. The edges of the sides and end faces (e.g., the edge of the first side face and the upstream end face, the edge of the upstream end face and the second side face, the edge of the second side face and the downstream end face, the edge of the downstream end face and the first side face) may be rounded. However, in some cases, the edges may be angular. Additionally, the peripheral edge of the front may be in the form of a ledge. The front of the nicotine-free pod assembly (300) may be wider and longer than the rear. In this case, the first side and the second side may be angled inward toward each other. The upstream end surface and the downstream end surface may also be angled inward toward each other. Due to the angled surface, the nicotine-free pod assembly (300) may be inserted unidirectionally (e.g., from the front of the device body (100) (the side connected to the front cover (104))). As a result, the possibility of the nicotine-free pod assembly (300) being improperly inserted into the device body (100) may be reduced or prevented.

[0062] As illustrated in FIG. 14, the upstream end of the nicotine-free pod assembly (300) may include at least one electrical contact and define at least one upstream recess (e.g., a first upstream recess (312a) and / or a second upstream recess (312b)), whereas as illustrated in FIG. 15, the downstream end of the nicotine-free pod assembly (300) may define a pod outlet (304) and at least one downstream recess (e.g., a first downstream recess (306a) and / or a second downstream recess (306b)). The pod body of the nicotine-free pod assembly (300) may include a first housing section (302) and a second housing section (308). The first housing section (302) of the pod body may be configured to store a nicotine-free vapor-free preparation, and the second housing section (308) may be configured to accommodate a connector module (320) (e.g., FIG. 17).

[0063] In an exemplary embodiment, the upstream end of the second housing section (308) of the pod body defines a cavity, while the downstream end of the first housing section (302) of the pod body defines a pod outlet (304) that is in fluid communication with the cavity of the second housing section (308). As described in more detail herein, a connector module (320) (e.g., FIG. 17) is configured to be seated within the cavity of the second housing section (308) of the pod body. The connector module (320) includes an outer face (e.g., having electrical contacts) and adjacent sides. When the nicotine-free pod assembly (300) is assembled, the outer face of the connector module (320) forms the exterior of the nicotine-free pod assembly (300), while the adjacent sides are hidden from view within the cavity of the second housing section (308). Accordingly, the outer surface of the connector module (320) may be part of the upstream end surface of the nicotine-free pod assembly (300).

[0064] The outer surface of the connector module (320) may include at least one electrical contact. The at least one electrical contact may include a plurality of power contacts. For example, the plurality of power contacts may include a first power contact (324a) and a second power contact (324b). Although FIG. 14 shows the first power contact (324a) and the second power contact (324b) extending horizontally outward, it should be understood that in other forms of the nicotine-free pod assembly (300), the first power contact (324a) and the second power contact (324b) may be folded upward so as to lean against the outer surface adjacent to the data contact (326) of the connector module (320). The first power contact (324a) of the nicotine-free pod assembly (300) is configured to be electrically connected to the first power contact of the device electrical connector (132) of the device body (100) (e.g., the power contact adjacent to the first upstream protrusion (128a) in FIG. 9). Similarly, the second power contact (324b) of the nicotine-free pod assembly (300) is configured to be electrically connected to the second power contact of the device electrical connector (132) of the device body (100) (e.g., the power contact adjacent to the second upstream protrusion (128b) in FIG. 9). Additionally, at least one electrical contact of the nicotine-free pod assembly (300) includes a plurality of data contacts (326). The plurality of data contacts (326) of the nicotine-free pod assembly (300) are configured to be electrically connected to the data contacts of the device electrical connector (132) (e.g., the row of six contacts in FIG. 9). In relation to the non-nicotine pod assembly (300), two power contacts and six data contacts are shown, but it should be understood that other variations are possible depending on the design of the device body (100).

[0065] As mentioned above, the pod body of the nicotine-free pod assembly (300) may include a first housing section (302) and a second housing section (308). The first housing section (302) has a downstream end defining the pod outlet (304). The rim of the pod outlet (304) may be a raised region. In this case, if the downstream end face of the first housing section (302) is angled inward, the degree of protrusion of the rim of the pod outlet (302) will increase toward the rear and decrease toward the front. Additionally, the rear-facing side of the pod outlet (304) may have a ramp extending upward from the downstream end face toward the rim. Consequently, when the nicotine-free pod assembly (300) is inserted into the through hole (150) of the device body (100), the advancement of the pod outlet (304) can be facilitated by the inclined portion so as to be aligned with the distal end of the mouthpiece (102). In a non-limiting embodiment, the distal end of the mouthpiece (102) includes or is made of an elastic material that facilitates the advancement of the nicotine-free pod assembly (300) into the through hole (150) of the device body (100) and assists in sealing around the pod outlet (304).

[0066] At least one downstream recess is additionally defined at the downstream end of the first housing section (302). In one embodiment, the at least one downstream recess is in the form of a first downstream recess (306a) and a second downstream recess (306b). A 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 be engaged with the first downstream protrusion (130a) and the second downstream protrusion (130b) of the device body (100), respectively. The first downstream recess (306a) and the second downstream recess (306b) may each be in the form of a dimple. In this case, the first downstream protrusion (130a) and the second downstream protrusion (130b) of the device body (100) may be a rounded structure (e.g., a spherical cap) configured to be connected to the corresponding first downstream concave (306a) and second downstream concave (306b).

[0067] Similarly, the upstream end of the second housing section (308) defines at least one upstream recess. In one embodiment, the at least one upstream recess is in the form of a first upstream recess (312a) and a second upstream recess (312b). The first power contact (324a) and the second power contact (324b) of the connector module (320) 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. The first upstream recess (312a) and the second upstream recess (312b) may also be in the form of dimples. In this case, the first upstream protrusion (128a) and the second upstream protrusion (128b) of the device body (100) may be of a round shape (e.g., a spherical cap) configured to be coupled with the corresponding first upstream concave (312a) and second upstream concave (312b).

[0068] The first housing section (302) may define a reservoir configured to hold a nicotine-free vapor-prescription. The reservoir may be configured to seal the nicotine-free vapor-prescription until the nicotine-free pod assembly (300) is activated and the nicotine-free vapor-prescription is released from the reservoir. As a result of sealing, the nicotine-free vapor-prescription may be isolated from the environment and separated from internal elements of the nicotine-free pod assembly (300) that may potentially react with the nicotine-free vapor-prescription, thereby reducing or preventing the possibility of adverse effects on the shelf life and / or sensorial properties (e.g., fragrance) of the nicotine-free vapor-prescription. The second housing section (308) may include a structure configured to activate the nicotine-free pod assembly (300) and to receive and heat the nicotine-free vapor-prescription released from the reservoir after activation.

[0069] An adult smoker may manually activate the nicotine-free pod assembly (300) before inserting the nicotine-free pod assembly (300) into the device body (100). Alternatively, it may be activated as part of inserting the nicotine-free pod assembly (300) into the device body (100). In an exemplary embodiment, the second housing section (308) of the pod body includes a perforator configured to release a nicotine-free vapor-free preparation from a reservoir during the activation of the nicotine-free pod assembly (300). The perforator may be in the form of a first operating pin (314a) and a second operating pin (314b), which will be described below in more detail.

[0070] To manually activate the nicotine-free pod assembly (300), an adult smoker may press the first actuating pin (314a) and the second actuating pin (314b) inward (e.g., simultaneously or sequentially) before inserting the nicotine-free pod assembly (300) into the through hole (150) of the device body (100). For example, the first actuating pin (314a) and the second actuating pin (314b) may be manually pressed until their ends substantially align with the upstream end face of the nicotine-free pod assembly (300). In one embodiment, when the first actuating pin (314a) and the second actuating pin (314b) move inward, the seal of the reservoir may be punctured or otherwise the reservoir may be exposed, allowing the nicotine-free vapor-prescription to be released.

[0071] Alternatively, to activate the nicotine-free pod assembly (300) as part of inserting the nicotine-free pod assembly (300) into the device body (100), the nicotine-free pod assembly (300) may be initially positioned so that the first actuating pin (314a) and the second actuating pin (314b) are in contact with the upstream sidewall of the through hole (150). Subsequently, the upstream end of the nicotine-free pod assembly (300) may be pressed toward the upstream sidewall of the through hole (150) so that the first actuating pin (314a) and the second actuating pin (314b) are pushed (e.g., simultaneously) into the second housing section (308), thereby transitioning from a protruding state to a retracted (contracted) state to release the nicotine-free vapor-prescription from the reservoir. When the pod electrical contact of the non-nicotine pod assembly (300) is adjacent to or in contact with the device electrical contact of the device body (100), the downstream end of the non-nicotine pod assembly (300) can move (e.g., pivot) into the through hole (150). As the non-nicotine pod assembly (300) advances into the through hole (150), the upstream fastening panel (156) and / or downstream fastening panel (158) flex, and spring back when the concave portion of the non-nicotine pod assembly (300) is engaged with the corresponding protrusion of the device body (100).

[0072] In an exemplary embodiment, when the nicotine-free pod assembly (300) is seated within the device body (100), the first upstream recess (312a) and the second upstream recess (312b) of the nicotine-free pod assembly (300) will be engaged with the first upstream protrusion (128a) and the second upstream protrusion (128b) of the bezel structure (112) (e.g., upstream engagement). Similarly, the first downstream recess (306a) and the second downstream recess (306b) of the nicotine-free pod assembly (300) will be engaged with the first downstream protrusion (130a) and the second downstream protrusion (130b) of the bezel structure (112), respectively (e.g., downstream engagement). Switching to upstream connection and / or downstream connection may produce an auditory click sound and / or tactile feedback indicating that the nicotine-free pod assembly (300) is properly seated within the through hole (150) of the device body (100).

[0073] When properly seated, the nicotine-free pod assembly (300) is mechanically, electrically, and fluidically connected to the device body (100). In some cases, the upstream connection of the nicotine-free pod assembly (300) is described as occurring before the downstream connection, but alternatively, it should be understood that in some cases, the downstream connection may occur before (or simultaneously with) the upstream connection. Other aspects of the connection between the non-nicotine pod assembly (300) and the device body (100) and the non-nicotine electronic smoking device (500) are described in U.S. Application No. 16 / 696,189, titled “Non-nicotine Pod Assemblies And Non-nicotine E-vaping Devices” (Atty. Dkt. No. 24000NV-000619-US) and U.S. Application No. 16 / 695,515, titled “Non-nicotine Pod Assemblies And Non-nicotine E-vaping Devices” (Atty. Dkt. No. 24000NV-000613-US), filed concurrently with this document, the entire contents of which are incorporated into this document by reference.

[0074] FIG. 16 is an exploded view including the first housing section of the nicotine-free pod assembly of FIG. 14. Referring to FIG. 16, the first housing section (302) includes a vapor channel (316). The vapor channel (316) is configured to receive nicotine-free vapor (from the second housing section (308)) and is in fluid communication with the pod outlet (304). In one embodiment, the vapor channel (316) may gradually increase in size (e.g., diameter) as it extends toward the pod outlet (304). Additionally, the vapor channel (316) may be formed integrally with the first housing section (302). An insert (342) and a seal (344) are placed at the upstream end of the first housing section (302) to define a reservoir of the nicotine-free pod assembly (300). When assembled, the insert (342) may elastically interface with the outer sidewall of the vapor channel (316). Additionally, the seal (344) is attached to the upstream rim of the first housing section (302) and to the upstream side of the insert (342) to provide fluid-tightness (e.g., liquid-tightness and / or air-tightness) of the nicotine-free vapor-prescription in the reservoir.

[0075] In an exemplary embodiment, the seal (344) defines an opening (e.g., a central opening) configured to align with the vapor channel (316) and provide adequate clearance to accommodate the downstream end of the vaporizer (336) (e.g., FIG. 17). In FIG. 16, it should be understood that the seal (344) is perforated. In particular, when perforated by the first actuating pin (314a) and the second actuating pin (314b) of the nicotine-free pod assembly (300), the two perforated sections of the seal (344) are pushed into the reservoir as flaps (Fig. 16), thereby creating two perforated openings in the seal (344) (e.g., one on each side of the central opening). Conversely, when not perforated, the seal (344) is flat and will have only one opening (e.g., a central opening). The seal (344) is designed to be sufficiently rigid so as not to be damaged during normal movement and / or handling of the nicotine-free pod assembly (300), thereby preventing premature / unintended damage. For example, the seal (344) may be a coated foil (e.g., aluminum-coated polyethylene terephthalate (PET)).

[0076] FIG. 17 is a partial exploded view relating to the second housing section of the nicotine-free pod assembly of FIG. 14. Referring to FIG. 17, the second housing section (308) is configured to include various components configured to release, receive, and heat a nicotine-free vapor-free preparation. For example, a first operating pin (314a) and a second operating pin (314b) are configured to perforate a reservoir of the first housing section (302) to release the nicotine-free vapor-free preparation. Each of the first operating pin (314a) and the second operating pin (314b) has a distal end extending through a corresponding opening of the second housing section (308). In an exemplary embodiment, the distal ends of the first actuating pin (314a) and the second actuating pin (314b) are visible after assembly (e.g., FIG. 14), while the remaining parts of the first actuating pin (314a) and the second actuating pin (314b) are hidden from view within the nicotine-free pod assembly (300). Additionally, each of the first actuating pin (314a) and the second actuating pin (314b) includes a proximal end positioned adjacent to the seal (344) and upstream of the seal (344) prior to the activation of the nicotine-free pod assembly (300). When the first actuating pin (314a) and the second actuating pin (314b) are pushed into the second housing section (308) to activate the nicotine-free pod assembly (300), the proximal ends of the first actuating pin (314a) and the second actuating pin (314b) advance, thereby perforating the seal (344), which will release the nicotine-free vapor-prescription from the reservoir. The movement of the first actuating pin (314a) may be independent of the movement of the second actuating pin (314b) (and vice versa). The first actuating pin (314a) and the second actuating pin (314b) will be described in more detail here.

[0077] In an exemplary embodiment, the rear surface of the second housing section (308) defines a pod inlet (e.g., FIG. 3). The pod inlet (in which air enters during smoking) is in fluid communication with the pod outlet (304) (in which nicotine-free vapor exits during smoking). The pod inlet may be located along the longitudinal axis of the nicotine-free pod assembly (300) (and the nicotine-free electronic smoking device (500)) and may be located adjacent to the upstream end of the second housing section (308), but exemplary embodiments are not limited thereto. Additionally, the pod inlet may be located between a pair of raised surfaces (e.g., ridges) on the rear surface of the second housing section (308). Thus, the raised surfaces help to reduce or prevent blockage of the pod inlet (in the event of inadvertent blockage by an adult smoker's finger(s) during smoking). The pod inlet is illustrated as being in the form of a slot (e.g., Fig. 3). However, it should be understood that the present invention is not limited thereto and other forms are possible.

[0078] The upstream end of the second housing section (308) defines a cavity (e.g., the bottom surface of the second housing section (308) based on the drawing in FIG. 17). As mentioned above, the cavity is configured to accommodate a connector module (320) (e.g., by interference fit). In an exemplary embodiment, the cavity is located between the first upstream recess (312a) and the second upstream recess (312b), and also between the first actuating pin (314a) and the second actuating pin (314b). In the absence of the connector module (320), the upstream end of the gasket (318) and the carburetor (336) (extending through the gasket (318)) may be visible through the cavity of the second housing section (308).

[0079] The vaporizer (336) is configured to receive and heat a nicotine-free vapor-free preparation released from the reservoir of the first housing section (302). As discussed in more detail below, the vaporizer (336) may include a heater and / or wick configured to receive and heat the nicotine-free vapor-free preparation. Additionally, the vaporizer (336) may be considered to have an upstream end, an opposing downstream end, and an intermediate sector between the upstream end and the downstream end. The upstream end of the vaporizer (336) is configured to extend through the second housing section (308) and gasket (318) to be connected to the connector module (320). For example, the upstream end of the vaporizer (336) may be seated within a corresponding socket of the connector module (320) (e.g., via a press fit). On the other hand, the downstream end of the vaporizer (336) is configured to extend through a seal (344) and an insert (342) to be connected to the vapor channel (316) of the first housing section (302). The middle sector of the vaporizer (336) defines an internal heating chamber provided with one or more openings configured to receive a nicotine-free vapor-free preparation released from the reservoir of the first housing section (302) when the nicotine-free pod assembly (300) is activated.

[0080] In an exemplary embodiment, the intermediate sector of the vaporizer (336) defines a pair of openings upstream of the seal (344). The vaporizer (336) may include a wick extending through both of the openings of the intermediate sector and / or inside them. The wick has pores / interstices designed for capillary action. Additionally, a heater may be provided within the heating chamber of the intermediate sector of the vaporizer (336) to make thermal contact with the wick. Consequently, a nicotine-free vapor-prescription released from the reservoir may be transported through the wick to the heater in the intermediate sector of the vaporizer (336). The heater is configured to heat the nicotine-free vapor-prescription during smoking to produce nicotine-free vapor. The heater may be electrically connected to the connector module (320) through at least one electrical contact. For example, one end of the heater (e.g., the first end) may be connected to the first power contact (324a), and the other end of the heater (e.g., the second end) may be connected to the second power contact (324b). The heater may include a coiled heating element. In this case, the wick may have a string-like shape, and the heater may wrap around at least a portion of the length of the wick (e.g., in a spiral manner). Alternatively, the heater may include a folded heating element. In this case, the wick may have a flat shape (e.g., a fibrous pad) configured to be secured by the folded heating element. Although various forms have been described in relation to the heater and wick, it should be understood that other configurations and combinations are possible.

[0081] The heater is configured to perform Joule heating (also called ohmic / resistance heating) when current is applied. More specifically, the heater may be composed of at least one conductor (resistive material) and configured to generate heat when current passes through it. Current may be supplied from a power source (e.g., battery) within the device body (100) and delivered to the heater (336) through a first power contact (324a) or a second power contact (324b). During smoking, the nicotine-free vapor generated by the heater is drawn from the heating chamber in the middle sector of the vaporizer (336), passes through the downstream end of the vaporizer (336), passes through the vapor channel (316) of the first housing section (302), exits the pod outlet (304) of the nicotine-free pod assembly (300), and flows through the vapor passage (136) of the mouthpiece (102) to the vapor outlet(s).

[0082] Suitable conductors (resistive materials) for the heater include iron-based alloys (e.g., stainless steel) and / or nickel-based alloys (e.g., nichrome). Wires formed from these materials can be wound to provide a coil-shaped heater. In other cases, the heater can be manufactured by stamping a conductive sheet (e.g., metal, alloy) to form a winding pattern. The winding pattern may have curved segments arranged alternately with horizontal segments, and the horizontal segments are arranged in a zigzag pattern back and forth while extending parallel. Additionally, 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 one embodiment is not limited thereto. To obtain a folded form for the heater, the winding pattern may be folded or bent (e.g., to provide a U-shaped cross section configured to accommodate and hold a wick). Heaters and associated structures are described in detail in U.S. Patent Application No. 15 / 729,909, "Folded Heater For Electronic Vaping Device" (Atty. Dkt. No. 24000-000371-US), filed on October 11, 2017, the entire contents of which are incorporated herein by reference.

[0083] FIG. 18 is an exploded view of the operating pin of FIG. 17. Referring to FIG. 17, the operating pin may be in the form of a first operating pin (314a) and a second operating pin (314b). Although two operating pins are illustrated and discussed in relation to an embodiment not limited to this document, it should be understood that alternatively, only one operating pin may be included in the nicotine-free pod assembly (300). In FIG. 18, the first operating pin (314a) may include a first blade (348a), a first actuator (350a), a first O-ring (352a), and a first cap (353a). Likewise, the second operating pin (314b) may include a second blade (348b), a second actuator (350b), a second O-ring (352b), and a second cap (353b).

[0084] In one embodiment, the first blade (348a) and the second blade (348b) may be configured to be mounted or attached to the upper portion (e.g., proximal portion) of the first actuator (350a) and the second actuator (350b), respectively. Mounting or attachment may be achieved through a snap-fit ​​connection, an interference fit (e.g., friction fit) connection, an adhesive, or other suitable joining technique. The upper portions of the first blade (348a) and the second blade (348b) have at least one curved edge or concave edge, which tapers upward to form a pointed tip. For example, the first blade (348a) and the second blade (348b) may each have two pointed tips separated by a concave edge and a curved edge adjacent to each pointed tip. The radius of curvature of the concave edge and the curved edge may be the same, but the arc lengths may differ. The first blade (348a) and the second blade (348b) may be made of sheet metal (e.g., stainless steel), cut or otherwise formed to have a desired profile, and bent into a final shape. As another example, the first blade (348a) and the second blade (348b) may be made of plastic.

[0085] Also, as shown in FIG. 18, the first actuator (350a) and the second actuator (350b) may include protruding edges (e.g., curved inner lips facing each other) configured to push the two perforated sections of the seal (344) into the reservoir as they advance into the reservoir. In one embodiment that is not limited, when the first actuating pin (314a) and the second actuating pin (314b) are fully inserted into the nicotine-free pod assembly (300), the two flaps (by the two perforated sections of the seal (344) as shown in FIG. 16) may be between the side walls of the insert (342) and the protruding edges of the first actuator (350a) and the second actuator (350b). As a result, the possibility of the two punctured openings in the seal (344) being blocked (by two flaps by two punctured sections) can be reduced or prevented. Additionally, the first actuator (350a) and the second actuator (350b) can be configured to guide a nicotine-free vapor-prescription from the reservoir toward the openings of the vaporizer (336) (guided into the heating chamber within the vaporizer).

[0086] The lower portion (e.g., distal portion) of each of the first actuator (350a) and the second actuator (350b) is configured to extend through the bottom portion (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 an axis. The first O-ring (352a) and the second O-ring (352b) may be placed on the respective shafts of the first actuator (350a) and the second actuator (350b). In an exemplary embodiment, the first cap (353a) may be used to help secure the first O-ring (352a) to the concave surface of the shaft of the first actuator (350a). Similarly, the second cap (353b) can be used to help secure the second O-ring (352b) to the concave surface of the shaft of the second drive (350b).

[0087] The first O-ring (352a) and the second O-ring (352b) are configured to be engaged with the inner surface of the corresponding opening of the shaft of the corresponding first actuator (350a) and the second actuator (350b) and the second housing section (308) to provide a fluid-tight seal. Consequently, when the first operating pin (314a) and the second operating pin (314b) are pushed inward to activate the nicotine-free pod assembly (300), the first O-ring (352a) and the second O-ring (352b) move together with the respective shafts of the first actuator (350a) and the second actuator (350b) within the corresponding openings in the second housing section (308) while maintaining their respective seals, thereby contributing to reducing or preventing leakage of the nicotine-free vapor-free preparation through the openings of the second housing section (308) for the first operating pin (314a) and the second operating pin (314b). The first O-ring (352a) and the second O-ring (352b) may be made of silicone.

[0088] FIG. 19 is an exploded view of the connector module of FIG. 17. Referring to FIG. 19, the module housing (354) and the face plate (366) generally form the external framework of the connector module (320). In particular, the connector module (320) may be considered to have a plurality of faces, including an external face and adjacent side faces. In an exemplary embodiment, the external face of the connector module (320) includes the upstream surface of the face plate (366) (e.g., the bottom surface of the face plate (366) with reference to FIG. 19). The side faces of the connector module (320) may be part of the module housing (354). Although not visible, the rear side face of the module housing (354) may define the module inlet (e.g., the side face of the module housing (354) angled toward the rear left with reference to FIG. 19). The sides may include a rib structure (e.g., a crush rib) configured to facilitate a press fit when the connector module (320) is seated within the cavity of the second housing section (308). For example, each side may include a pair of ribs that taper away from the faceplate (366). Consequently, the module housing (354) will face increased resistance through friction of the rib structure against the walls of the cavity when the connector module (320) is pressed into the cavity of the second housing section (308). When the connector module (320) is properly seated, the module inlet of the module housing (354) will be aligned with the pod inlet of the second housing section (308).

[0089] The sensor (364), the first power contact (324a), the second power contact (324b), and the printed circuit board (PCB) (362) are placed within an external framework formed by the module housing (354) and the faceplate (366). In an exemplary embodiment, the sensor is configured to detect and / or measure air flow into the nicotine-free pod assembly (300). For example, the sensor (364) may be a hot-wire anemometer positioned so that a wire portion extends across the module inlet of the module housing (354). The faceplate (366) defines a plurality of contact openings. The data contact (326) is configured to extend through the corresponding contact opening of the faceplate (366) to be electrically connected to the printed circuit board (362).

[0090] Each of the first power contact (324a) and the second power contact (324b) may be considered to have a body portion, an arm portion, a finger portion, and a leg portion. When assembled, the body portions of the first power contact (324a) and the second power contact (324b) may be adjacent to the rear side face of the module housing (354) (e.g., the side face of the module housing (354) angled toward the rear left with reference to FIG. 19). Additionally, the arm portions of the first power contact (324a) and the second power contact (324b) may be adjacent to the lateral side faces of the module housing (354) (e.g., two sides extending from the rear side face). The finger portions of the first power contact (324a) and the second power contact (324b) may each be in the form of two fingers that are electrically connected to the heater of the vaporizer (336) (e.g., via an electrical lead) when the upstream end of the vaporizer (336) is seated within the corresponding socket defined by the module housing (354) of the connector module (320). When the faceplate (366) is set in place and connected to the module housing (354), the leg portions of the first power contact (324a) and the second power contact (324b) may be bent to be against or adjacent to the upstream surface of the faceplate (336) (e.g., the underside of the faceplate (366) with reference to FIG. 19). Accordingly, when assembled, the printed circuit board (362) can be considered to be surrounded on at least four sides by the serrated structure of the first power contact (324a) and the second power contact (324b).

[0091] The resistance-to-draw of the nicotine-free electronic smoking device (500) can be adjusted by changing the size of the module outlet (of the module housing (354)) instead of changing the size of the pod inlet (of the second housing section (308)). In one embodiment, the size of the module inlet can be selected so that the resistance-to-draw is 25 to 100 mmH2O (e.g., 30 to 50 mmH2O). For example, if the diameter of the module inlet is 1.0 mm, a resistance-to-draw of 88.3 mmH2O may occur. In another case, if the diameter of the module inlet is 1.1 mm, a resistance-to-draw of 73.6 mmH2O may occur. In yet another case, if the diameter of the module inlet is 1.2 mm, a resistance-to-draw of 58.7 mmH2O may occur. In another case, if the diameter of the module inlet is 1.3 mm, a suction resistance of about 40 to 43 mmH2O may occur.

[0092] In an exemplary embodiment, the pod inlet of the second housing section (308) is larger than the module inlet of the module housing (354). In this example, the module inlet of the module housing (354) may be a limiting factor related to the flow of air into the nicotine-free pod assembly (300). The size of the module inlet can be adjusted without affecting the external appearance of the nicotine-free pod assembly (300) because it is placed internally, thus enabling a more standardized product design for nicotine-free pod assemblies with various resistances to inhalation (RTD) and also reducing the possibility of accidental blockage of incoming air. Other aspects of the non-nicotine pod assembly (300) as well as the non-nicotine electronic smoking device (500) are described in U.S. Application No. 16 / 696,018, titled “Non-nicotine Pod Assemblies And Non-nicotine E-vaping Devices” (Atty. Dkt. No. 24000NV-000623-US), filed concurrently with this document, the entire contents of which are incorporated herein by reference.

[0093] In an exemplary embodiment, the nicotine-free vapor-preparation does not contain tobacco and is not derived from tobacco. The nicotine-free compound of the nicotine-free vapor-preparation may be contained in or in the form of a liquid or partial liquid comprising an extract, oil, alcohol, tincture, suspension, dispersion, colloid, general non-neutral (slightly acidic or slightly basic) solution, or a combination thereof. While preparing the nicotine-free vapor-preparation, the nicotine-free compound may be infused into, comeled into, or otherwise combined with other components of the nicotine-free vapor-preparation.

[0094] In one embodiment, the nicotine-free compound undergoes a slow, natural decarboxylation process over a long period of time at relatively low temperatures, including room temperature (e.g., 72 °F) or below. Additionally, the nicotine-free compound may undergo a significantly high decarboxylation process (e.g., more than 50% decarboxylation) when exposed to elevated temperatures, particularly at temperatures above about 175 °F, especially at relatively low pressures such as 1 atm. At higher temperatures above about 240 °F, decarboxylation may occur rapidly or immediately with a relatively high decarboxylation rate, but further increases in temperature may degrade some or all of the chemical properties of the nicotine-free compound.

[0095] In one embodiment, the nicotine-free compound may be derived from a medicinal plant (e.g., a naturally occurring component of a plant that provides a medically acceptable therapeutic effect). The medicinal plant may be a cannabis plant, and the component may be at least one cannabis-derived component. Cannabinoids (e.g., phytocannabinoids) and terpenes are examples of cannabis-derived components. Cannabinoids interact with receptors in the body to produce a wide range of effects. As a result, cannabinoids have been used for various medical purposes. Cannabis-derived material may include leaf and / or flower material of one or more cannabis plant species or extracts derived from one or more cannabis plant species. For example, one or more cannabis plant species may include cannabis sativa, cannabis indica, and cannabis ruderalis. In one embodiment, a nicotine-free vapor-free formulation comprises a mixture of 60-80% (e.g., 70%) cannabis sativa and 20-40% (e.g., 30%) cannabis indica and / or a mixture of cannabis-derived ingredients derived therefrom.

[0096] Non-limiting examples of cannabis-derived cannabinoids include tetrahydrocannabinolic acid (THCA), tetrahydrocannabinol (THC), cannabidiolic acid (CBDA), cannabidiol (CBD), cannabinol (CBN), cannabicyclol (CBL), cannabichromene (CBC), and cannabigerol (CBL). Tetrahydrocannabinolic acid (THCA) is a precursor of tetrahydrocannabinol (THC), and cannabidiolic acid (CBDA) is a precursor of cannabidiol (CBD). Tetrahydrocannabinol acid (THCA) and cannabidiol acid (CBDA) can be converted into tetrahydrocannabinol (THC) and cannabidiol (CBD), respectively, through heating. In one embodiment, the heat of a heater causes decarboxylation to convert tetrahydrocannabinol acid (TCHA) of a nicotine-free vapor-prescription to tetrahydrocannabinol (THC), and / or convert cannabidiol acid (CBDA) of a nicotine-free vapor-prescription (21) to cannabidiol (CBD).

[0097] When both tetrahydrocannabinol (THCA) and tetrahydrocannabinol (THC) are present in a nicotine-free vapor-preparation, decarboxylation and the resulting conversion cause a decrease in tetrahydrocannabinol (THCA) and an increase in tetrahydrocannabinol (THC). During heating of the nicotine-free vapor-preparation for vaporization purposes, at least 50% (e.g., at least 87%) of tetrahydrocannabinol (THCA) may be converted to tetrahydrocannabinol (THC) through the decarboxylation process. Similarly, when both cannabidiol (CBDA) and cannabidiol (CBD) are present in the nicotine-free vapor-preparation, decarboxylation and the resulting conversion will cause a decrease in cannabidiol (CBDA) and an increase in cannabidiol (CBD). While heating a nicotine-free vapor-prepared preparation for the purpose of vaporization, at least 50% (e.g., at least 87%) of cannabidiol acid (CBDA) can be converted to cannabidiol (CBD) through a decarboxylation process.

[0098] Nicotine-free vapor-preparations may include nicotine-free compounds that provide medically recognized therapeutic effects (e.g., treatment of pain, nausea, epilepsy, and mental disorders).
