[0063] 1A-1C, the non-nicotine e-vaporizing device 100 includes a non-nicotine vapor generation assembly 110 and a power supply assembly 210. In some exemplary embodiments, the non-nicotine vapor generation assembly 110 and the power supply assembly 210 include respective complementary connector assemblies 142, 232 and are configured to releasably connect to one another based on releasably coupling the connector assemblies 142, 232 to one another. In some exemplary embodiments, the non-nicotine vapor generation assembly 110 configured to releasably couple to the power supply assembly 210 to form the non-nicotine e-vaporizing device 100 may be referred to herein as a cartridge. In some exemplary embodiments, the connector assembly 142 includes a threaded connector. It should be understood that the connector assembly 142, 232 may be any type of connector, including, but not limited to, a snug fit, a detent, a clamp, a bayonet, a slide fit, a sleeve fit, an alignment fit, a threaded connector, a magnetic, a clasp, or any other type of connection, and / or a combination thereof. In some exemplary embodiments, the non-nicotine e-vaporizing device 100 may be an integral part that includes the non-nicotine vapor generation assembly 110 and the power supply assembly 210 in an integral part, rather than as separate parts that are joined together to form the non-nicotine e-vaporizing device 100.

[0064] As shown at least in Figures 2A-2D, the non-nicotine vapor generation assembly 110 may include at least a reservoir 119 configured to hold a non-nicotine pre-vapor formulation, a non-nicotine vaporizer assembly 400 configured to heat the non-nicotine pre-vapor formulation drawn from the reservoir 119 to generate a non-nicotine vapor, and an isolation structure 188 configured to adjustably expose or isolate the non-nicotine vaporizer assembly 400 from the reservoir 119. As further shown, the non-nicotine vapor generation assembly 110 may include an outlet assembly 112, although it will be understood that in some exemplary embodiments, the outlet assembly 112 may be omitted. As shown in Figures 1A-1C, the reservoir 119 and isolation structure 188 may be included in a reservoir assembly 114 in some exemplary embodiments, and the reservoir assembly 114 and the non-nicotine vaporizer assembly 400 may be coupled together to at least partially provide the non-nicotine vapor generation assembly 110. The isolation structure 188 and its connections with the elements of the reservoir assembly 114 are illustrated in further detail in Figures 4 and 5A-5C.

[0065] A non-nicotine pre-vapor formulation is a material or combination of materials that does not contain nicotine and can be converted into a non-nicotine vapor. For example, a non-nicotine pre-vapor formulation may include liquid, solid, and / or gel formulations. These may be solutions and suspensions (e.g., emulsions) that include, for example, but are not limited to, water, oil, beads, solvents, active ingredients, ethanol, plant extracts, non-nicotine compounds, natural or artificial flavors, vapor formers such as glycerin and propylene glycol, and / or any other ingredients that may be suitable for vaping.

[0066] In some exemplary embodiments, the non-nicotine prevapor formulation does not contain tobacco or is not derived from tobacco. The non-nicotine compound of the non-nicotine prevapor formulation may be part of or contained in a liquid or partial liquid, including an extract, oil, alcohol, tincture, suspension, dispersion, colloid, general non-neutral (weakly acidic or weakly basic) solution, or a combination thereof. During the preparation of the non-nicotine prevapor formulation, the non-nicotine compound may be injected, mixed, or otherwise combined with other components of the non-nicotine prevapor formulation.

[0067] In some exemplary embodiments, the non-nicotine compounds undergo a slow, natural decarboxylation process over an extended period of time at relatively low temperatures, including room temperature (e.g., 72° F.) or below. Additionally, the non-nicotine compounds may undergo a significantly increased decarboxylation process (e.g., greater than 50% decarboxylation) when exposed to relatively low pressures, such as 1 atmosphere, for a period of time (minutes or hours), particularly elevated temperatures in the range of about 175° F. or above. High temperatures of about 240° F. or above can cause rapid or instantaneous decarboxylation with a relatively high decarboxylation rate, but even higher temperatures may cause some or all of the degradation of the chemical properties of the non-nicotine compound(s).

[0068] In some exemplary embodiments, the non-nicotine compound may be derived from a medicinal plant (e.g., a naturally occurring component of a plant that provides a medically recognized 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 and produce a variety of effects. As such, cannabinoids are used for a variety of medicinal purposes. The cannabis-derived material may include leaf and / or flower material from one or more species of cannabis plants, or an extract from one or more species of cannabis plants. For example, the one or more species of cannabis plants may include Cannabis sativa, Cannabis indica, and Cannabis ruderalis. In some exemplary embodiments, the non-nicotine prevapor formulation is 60-80% (e.g., 70%) Cannabis sativa and 20-40% (e.g., 30%) Cannabis indica, or includes a mixture of cannabis and / or cannabis-derived components.

[0069] Non-limiting examples of cannabinoids derived from cannabis include tetrahydrocannabinolic acid (THCA), tetrahydrocannabinol (THC), cannabidiol acid (CBDA), cannabidiol (CBD), cannabinol (CBN), cannabicyclol (CBL), cannabichromene (CBC) and cannabigerol (CBG). Tetrahydrocannabinolic acid (THCA) is the precursor of tetrahydrocannabinol (THC), and cannabidiol acid (CBDA) is the precursor of cannabidiol (CBD). Tetrahydrocannabinolic acid (THCA) and cannabidiol acid (CBDA) can be converted to tetrahydrocannabinol (THC) and cannabidiol (CBD), respectively, via heating. In some exemplary embodiments, the heat from the heater may cause decarboxylation to convert tetrahydrocannabinolic acid (THCA) in the non-nicotine pre-vapor formulation to tetrahydrocannabinol (THC), and / or decarboxylation to convert cannabidiolic acid (CBDa) in the non-nicotine pre-vapor formulation to cannabidiol (CBD).

[0070] In examples where both tetrahydrocannabinolic acid (THCA) and tetrahydrocannabinol (THC) are present in the non-nicotine pre-vapor formulation, decarboxylation and the resulting conversion will result in a decrease in tetrahydrocannabinolic acid (THCA) and an increase in tetrahydrocannabinol (THC). At least 50% (e.g., at least 87%) of tetrahydrocannabinolic acid (THCA) may be converted to tetrahydrocannabinol (THC) via a decarboxylation process during heating of the non-nicotine pre-vapor formulation for vaporization purposes. Similarly, in examples where both cannabidiolic acid (CBDA) and cannabidiol (CBD) are present in the non-nicotine pre-vapor formulation, decarboxylation and the resulting conversion will cause a decrease in cannabidiolic acid (CBDA) and an increase in cannabidiol (CBD). At least 50% (e.g., at least 87%) of cannabidiol acid (CBDA) may be converted to cannabidiol (CBD) via a decarboxylation process during heating of the non-nicotine pre-vapor formulation for vaporization purposes.

[0071] Non-nicotine prevapor formulations may include non-nicotine compounds that provide a medically recognized therapeutic effect (e.g., treatment of pain, nausea, epilepsy, psychiatric disorders). Details of the therapeutic methods are described in U.S. Application No. 15 / 845,501, entitled "VAPORIZING DEVICES AND METHODS FOR DELIVERING A COMPOUND USING THE SAME," filed December 18, 2017, the disclosure of which is incorporated herein by reference in its entirety.

[0072] In some exemplary embodiments, the at least one flavor valant is present in an amount ranging from about 0.2% to about 15% (e.g., about 1% to 12%, about 2% to 10%, or about 5% to 8%) based on the total weight of the non-nicotine prevapor formulation. The at least one flavor valant may be at least one of a natural flavor valant, an artificial flavor valant, or a combination of a natural flavor valant and an artificial flavor valant. The at least one flavor valant may include volatile cannabis flavor compounds (flavonoids) or other flavor compounds instead of or in addition to cannabis flavor compounds. For example, the at least one flavor valant may include menthol, wintergreen, peppermint, cinnamon, clove, combinations thereof, and / or extracts thereof. Additionally, flavor valant may be included to provide other herbal flavors, fruit flavors, nut flavors, booze flavors, roasted flavors, mint flavors, savory flavors, combinations thereof, and any other desired flavors.

[0073] 1A-1C, 2C-2D, and 5A-5B, reservoir assembly 114 may include upper structure 150, lower structure 122, outer housing 118, and inner housing 130, which may collectively define, at least in part, reservoir 119 as an annular space bounded by respective surfaces of at least upper structure 150, lower structure 122, outer housing 118, and inner housing 130. As shown, reservoir assembly 114 may be configured to hold a non-nicotine pre-vapor formulation within reservoir 119.

[0074] 2A-2D, the ring gasket 126 may establish a seal between the interface of the upper structure 150 and the inner surface of the outer housing 118, and the ring gasket 124 may establish a seal between the interface of the lower structure 122 and the inner surface of the outer housing 118 to mitigate leakage of the non-nicotine pre-vapor formulation from the reservoir 119 to the outside of the reservoir assembly 114 via said interface. The inner housing 130 may be coupled to the lower structure 122 via respective, complementary connectors 312, 311, and the ring gasket 318 may establish a seal between the interface of the inner housing 130 and the lower structure 122 to mitigate leakage of the non-nicotine pre-vapor formulation from the reservoir 119 to the outside of the reservoir assembly 114 via said interface. As shown, the connectors 311, 312 may include threaded connectors, however, it should be appreciated that the connectors 311, 312 may be any type of connector including, but not limited to, snug fit, detent, clamp, bayonet, slide fit, sleeve fit, alignment fit, threaded connector, magnetic, clasp, or other types of connections, and / or combinations thereof.

[0075] As shown at least in FIG. 2D, the superstructure 150 may include one or more fluid ports 150-o, also referred to as one or more second fluid ports, extending through the superstructure 150 between the reservoir 119 and at least an exterior of the reservoir 119, the one or more fluid ports 150-o adapted to allow fluid communication between the reservoir 119 and at least an exterior of the reservoir 119. As shown at least in FIG. 1C and FIG. 2C-2D, the reservoir assembly 114 may include a coupling structure 160 configured to abut the superstructure 150 and to rotate about a longitudinal axis 201 of the reservoir assembly 114 relative to the superstructure 150. A ring gasket 165 may seal an interface between the superstructure 150 and the coupling structure 160 to mitigate leakage of the non-nicotine prevapor formulation from the reservoir 119 via said interface. The coupling structure 160 may include one or more fluid ports 160-o extending therethrough. As shown in at least FIG. 2D , in some exemplary embodiments, each fluid port 150-o may be aligned with another fluid port 160-o in a direction extending coaxially with a longitudinal axis 201, where the reservoir assembly 114 is configured to enable fluid communication between the reservoir assembly 114 and the exterior of the reservoir assembly 114 via the longitudinally aligned fluid ports 150-o, 160-o. In some exemplary embodiments, the coupling structure 160 is configured to rotate about the longitudinal axis 201 relative to the superstructure 150 to adjustably longitudinally align or misalign the one or more fluid ports 160-o with the one or more fluid ports 150-o, thereby exposing or isolating the reservoir 119 to the exterior of the reservoir assembly 114 to allow the reservoir 119 to be refilled with a non-nicotine prevapor formulation.

[0076] 1C and 2C-2D, the reservoir assembly 114 may include a port adjustment ring 116 connected to the coupling structure 160 and configured to rotate the coupling structure 160 about the longitudinal axis 201 based on the port adjustment ring 116 being rotated about the longitudinal axis 201. For example, the port adjustment ring 116 may be secured to the coupling structure 160 via adhesive, welding, a bolted connection, a threaded connection, a bayonet connection, or the like. Thus, the reservoir assembly 114 may be configured to enable manual rotation of the coupling structure 160 relative to the upper structure 150 to adjustably expose or isolate the reservoir 119 to an exterior of the reservoir assembly 114 via longitudinally aligned or misaligned ports 160-o, 150-o.

[0077] 1C and 2C-2D, the non-nicotine vapor generation assembly 110 can include an outlet assembly 112 configured to removably engage with the coupling structure 160 to reversibly expose or isolate one or more ports 160-o from an exterior of the non-nicotine vapor generation assembly 110 and further establish fluid communication between a conduit extending from the non-nicotine vaporizer assembly 400 to an exterior of the non-nicotine vapor generation assembly 110 (described further below) via an outlet 251. As shown, the outlet assembly 112 includes an inner conduit 112-i configured to receive a nose portion of the coupling structure 160. The outlet assembly 112 further includes a protruding structure 314 that protrudes from an inner surface of the inner conduit 112-i and is configured to be received in a groove structure 160-g of the coupling structure 160 to seal an interface between the conduit 112-i and the nose section 160-1 of the coupling structure 160 to mitigate fluid passing through the inner conduit 112-i from exiting the outlet assembly 112 through a path other than the outlet 251. As shown in FIGS. 2C-2D, the outlet assembly 112 is configured to establish a bayonet connection with a port adjustment ring 116. The port adjustment ring 116 includes a plug bayonet connector 117, and the outlet assembly 112 includes a channel bayonet connector 113 that is complementary to the plug bayonet connector 117. As a result, the outlet assembly 112 is configured to engage the channel bayonet connector 113 with the plug bayonet connector 117 to establish a removable bayonet connection between the outlet assembly 112 and the coupling structure 160, thereby establishing a removable bayonet connection between the reservoir assembly 114 and the outlet assembly 112.

[0078] 1C and 2A-2D, the outlet assembly 112 is configured to cover one or more ports 160-o of the coupling structure 160 based on establishing a detachable bayonet connection between the outlet assembly 112 and the coupling structure 160. When the outlet assembly 112 is coupled to the reservoir assembly 114 via the bayonet connection between the outlet assembly 112 and the coupling structure 160, the outlet assembly 112 is configured to isolate the one or more ports 160-o from the outside of the non-nicotine vapor generating assembly 110, thus mitigating leakage of the non-nicotine pre-vapor formulation from the reservoir 119 via the ports 150-o, 160-o. Additionally, the non-nicotine vapor generation assembly 110 may be configured to expose the reservoir 119 to the outside of the non-nicotine vapor generation assembly 110 based on both the outlet assembly 112 being removed from the connecting structure 160 and the connecting structure 160 being further rotated about the longitudinal axis 201 to longitudinally align one or more ports 160-o of the connecting structure 160 with one or more ports 150-o of the upper structure 150.

[0079] 1C and 2C-2D, the inner housing 130 is connected to the superstructure 150 and secured in place relative to the superstructure 150 (e.g., via adhesive, connectors, etc.). As shown, the inner surface of the inner housing 130 at least partially defines a barrel conduit 130-a and a nose conduit 130-i configured to receive at least a portion of the non-nicotine vaporizer assembly 400 such that the non-nicotine vaporizer assembly 400 can be coupled with the reservoir assembly 114 to at least partially establish the non-nicotine vapor generation assembly 110.

[0080] As shown in Figures 2C-2D and 5A-5B, the inner housing 130 defines a lower portion (barrel conduit 130-a) and an upper portion (nose conduit 130-i), where the conduit 130-i has a diameter at least as large as the outer diameter of the nose segment 176-n of the non-nicotine vaporizer assembly 400, and the barrel conduit 130-a has a diameter at least as large as the outer diameter of the outer housing 320 of the non-nicotine vaporizer assembly 400.

[0081] 2C-2D, upper structure 150 includes conduits 150-i configured to be aligned with nose conduits 130-i about longitudinal axis 201 and flush or substantially flush with the inner surface of inner housing 130 such that conduits 130-i and 150-i collectively define a single continuous conduit.

[0082] 1A-2D and 4 and 5A-5C, reservoir assembly 114 includes an isolation structure 188 connected to coupling structure 160 and fixed in place relative to coupling structure 160 (e.g., via adhesive, welding, connectors, etc.), such that coupling structure 160 is configured to rotate with coupling structure 160 about longitudinal axis 201. As shown in at least FIGS. 2C-2D and 4-5B, isolation structure 188 includes barrel structure 188-1 having an inner surface defining barrel conduit 188-o and nose structure 188-2 having an inner surface defining narrower nose conduit 188-i. 2C-2D and 4-5B, nose structure 188-2 is secured to coupling structure 160 such that nose conduit 188-i is directly adjacent conduit 160-i, at least a portion of nose structure 188-2 and coupling structure 160 occupy the conduit defined by conduits 130-i and 150-i, barrel structure 188-1 occupies conduit 130-i, and nose structure 188-2 is secured to coupling structure 160 such that nose structure 188-2 is adjacent conduit 190-i. In some exemplary embodiments, the outer diameters of barrel structure 188-1 and nose structure 188-2 may correspond to the inner diameters of conduits 130-a and 130-i, respectively, such that there is no or substantially no intervening space between the outer surface of isolation structure 188 and the inner surface of inner housing 130, although exemplary embodiments are not limited thereto.

[0083] 2C-2D, nose structure 188-2 defines conduit 188-i and barrel structure 188-1 defines conduit 188-a that is wider than conduit 188-i. Additionally, coupling structure 160 includes conduit 160-i that is aligned with conduit 188-i about longitudinal axis 201 and configured to have an inner surface that is flush or substantially flush with an inner surface of nose structure 188-2, such that conduits 188-i and 160-i collectively define a single continuous conduit.

[0084] As shown, conduits 188-i and 160-i are configured to collectively define a conduit that establishes fluid communication between conduit 188-a and the exterior of reservoir assembly 114, independent of reservoir 119. As further shown in Figures 2C-2D, outlet assembly 112 is configured to removably connect to coupling structure 160 such that a nose portion of coupling structure 160 from which conduit 160-i extends is inserted into inner conduit 112-i of the outlet assembly, and outlet 251, inner conduit 112-i, and conduits 160-i and 188-i define fluid communication between conduit 188-a and the exterior of non-nicotine vapor generation assembly 110, independent of reservoir 119.

[0085] 2C-2D and 5A-5B, the inner housing 130 includes one or more ports 132 (also referred to herein as one or more first fluid ports) that extend through the inner housing 130 to establish fluid communication between the reservoir 119 and the conduit 130-a. As further shown, the isolation structure 188 may include one or more ports 188-o (also referred to herein as one or more third fluid ports) that extend through the barrel structure 188-1 to establish fluid communication between the barrel conduit 188-a and the exterior of the isolation structure 188. Based on being fixed to a coupling structure 160 configured to rotate about a longitudinal axis 201, the isolation structure 188 can be configured to rotate about the longitudinal axis 201 to adjustably radially align or misalign one or more ports 188-o with one or more ports 132 of the inner housing 130 to adjustably expose the barrel conduit 188-a to the reservoir 119 or to isolate the isolation structure 188 from the reservoir 119.

[0086] 1A-1C, a power supply assembly 210 of the non-nicotine e-vaporizing device 100 is described. With reference to FIG. 1C, the exemplary power supply assembly 210 may include an outer housing 212 and an end cap 214 that at least partially define a housing. As shown, a power supply 220 may be included within the housing of the power supply assembly 210. The power supply 220 may be a rechargeable battery, and the power supply assembly 210 may be configured to provide power from the power supply 220 to the non-nicotine vapor generation assembly 110 (e.g., via one or more electrical leads to the non-nicotine vaporizer assembly 400) to assist in non-nicotine vapor generation in the non-nicotine vaporizer assembly 400.

[0087] As shown in FIG. 1C, the exemplary non-nicotine e-vaporizing device 100 may include one or more instances of a control circuit 222 that may be configured to control the supply of power from the power source 220 to the non-nicotine vapor generation assembly 110 (e.g., to the non-nicotine vaporizer assembly 400). In the exemplary embodiment shown in FIG. 1B, the control circuit 222 is included in the power source assembly 210 and is structurally supported therein by one or more instances of the support structure 218. It will be understood that in some exemplary embodiments, the control circuit 222 may be included in the non-nicotine vapor generation assembly 110 instead of the power source assembly 210. In some exemplary embodiments, the non-nicotine e-vaporizing device 100 may be a unitary piece included in a unitary piece, rather than including the non-nicotine vapor generation assembly 110 and the power source assembly 210 as separate parts that are coupled together to form the non-nicotine e-vaporizing device 100.

[0088] As shown in FIGS. 1A-1C, the power supply assembly 210 includes an initialization interface 216 configured to be manually operated to cause the control circuit 222 to supply power to the non-nicotine vapor generating assembly 110. As shown, the initialization interface 216 may be a button device, but exemplary embodiments are not limited thereto. For example, the initialization interface 216 may be a switch device. Still referring to FIGS. 1A-1C, the power supply assembly 210 may include a power supply interface 228 configured to connect with a power supply conduit to allow the power supply 220 to be charged or recharged via power supplied thereto from an external power source via the power supply interface 228. In some exemplary embodiments, the power supply interface 228 may be a universal serial bus (USB) interface, a mini USB interface, a micro USB interface, or the like.

[0089] In some exemplary embodiments in which the non-nicotine vapor generation assembly 110 and the power supply assembly 210 are configured to be removably coupled via complementary connector assemblies 142, 323, respectively, one or more electrical circuits may be established through the non-nicotine vapor generation assembly 110 and the power supply assembly 210 upon coupling of the connector assemblies 142, 232. In one example, the one or more established electrical circuits may include at least the non-nicotine vaporizer assembly 400, the control circuitry 222, and the power supply 220. As shown at least in FIG. 1C, the power supply assembly 210 may include an electrode structure 230 electrically coupled to the power supply 220 and the control circuitry 222 via an electrical connection structure 226. As shown, the electrode structure 230 is configured to contact a corresponding electrode structure 172 of the non-nicotine vaporizer assembly 400 upon mating of the connector 323 of the power supply assembly 210 with the connector assembly 142 of the non-nicotine vapor generation assembly 110, and establish an electrical circuit including at least the power supply 220, the control circuit 222, and the non-nicotine vaporizer assembly 400, thereby electrically coupling the power supply 220 and the control circuit 222 with the non-nicotine vaporizer assembly 400. In the exemplary embodiment shown, the electrode structures 230 and 172 are configured to contact each other via flush contact of the respective surfaces of the electrode structures 230 and 172.

[0090] 1A-1C, the non-nicotine e-vaporizing device 100 may include an air inlet 250 configured to direct air drawn into the interior of the non-nicotine e-vaporizing device 100. The non-nicotine e-vaporizing device 100 may also include one or more conduits configured to draw in the non-nicotine vaporizer assembly 400 and entrain non-nicotine vapor generated therein, and to draw out of the non-nicotine e-vaporizing device 100 via the conduits 188-i, 160-i, 112-i, and the outlet 251 of the outlet assembly 112. As shown, the air inlet 250 may be an arcuate and / or annular inlet extending partially or entirely around the circumference of the exterior of the non-nicotine e-vaporizing device 100. In the exemplary embodiment shown, the air inlet 250 is defined by a gap between the coupled non-nicotine vapor generation assembly 110 and power supply assembly 210, although exemplary embodiments are not limited thereto. The air inlet 250 may be located entirely within and entirely defined by the non-nicotine vapor generation assembly 110 or the power supply assembly 210. As further shown, the power supply assembly 210 may include a structure 224 that at least partially defines one or more conduits that extend from the air inlet 250 through at least the interior of the power supply assembly 210 toward the non-nicotine vaporizer assembly 400.

[0091] The power supply assembly 210 further includes an adjustment ring 120 defining one or more orifices 121, which may be configured to be rotated, at least relative to the structure 224. The adjustment ring 120 may be configured to be rotated about a longitudinal axis of the power supply assembly 210 to align one or more differently sized orifices 121 with at least one air conduit defined by the structure 224 to adjustably configure the non-nicotine e-vaporizing device 100 to support a particular maximum flow rate of air through the non-nicotine e-vaporizing device via flow choking by the orifices 121 aligned with the conduit defined by the structure 224. In some exemplary embodiments, the adjustment ring 120 may be configured to rotate to separate the conduit defined by the structure 224 to prevent air from being drawn into the non-nicotine vaporizer assembly 400 from the air inlet 250.

[0092] Still referring to at least FIG. 1C , the structure 224 further defines a space that is coupled to the connector 323 and configured to be in fluid communication with the inlet conduit 178-i of the non-nicotine vaporizer assembly 440 when the connector 323 is connected to the connector assembly 142 of the non-nicotine vapor generating assembly 110.

[0093] In some exemplary embodiments, the non-nicotine e-vaporizing device 100 may be a one-piece unitary piece that integrally includes the non-nicotine vapor generation assembly 110 and the power supply assembly 210, eliminating the need to couple the non-nicotine vapor generation assembly 110 and the power supply assembly 210 together to establish one or more electrical circuits.

[0094] In some exemplary embodiments, power source 220 may include a battery. In some examples, power source 220 may include a lithium ion battery or one of its variants, such as a lithium ion polymer battery, or a different type of battery. Additionally, power source 220 may be rechargeable and may include circuitry configured to enable the battery to be rechargeable by an external charging device.

[0095] In some exemplary embodiments, the power source 220 may be electrically connected to the non-nicotine vaporizer assembly 400 by the control circuit 222 based on a signal received by the control circuit 222 from a sensor of the non-nicotine e-vaporizing device 100, an interface of the non-nicotine e-vaporizing device 100 (e.g., the initialization interface 216), or a combination thereof. To control the supply of power to the non-nicotine vaporizer assembly 400, the control circuit 222 may execute one or more instances of computer-executable program code. The control circuit 222 may include a processor and a memory. The memory may be a computer-readable storage medium that stores the computer-executable code. The control circuit 222 may be a special purpose machine configured to execute the computer-executable code to control the supply of power to the non-nicotine vaporizer assembly 400.

[0096] 3A-3D, a non-nicotine vaporizer assembly 400 is described. FIGS. 3A-3B are perspective views of a non-nicotine vaporizer assembly according to some exemplary embodiments. FIG. 3C is a cross-sectional perspective view of the non-nicotine vaporizer assembly of FIGS. 3A-3B along line IIIC-IIIC' according to some exemplary embodiments. FIG. 3D is a cross-sectional perspective view of the non-nicotine vaporizer assembly of FIGS. 3A-3B along line IIID-IIID' according to some exemplary embodiments.

[0097] 3A-3D, the non-nicotine vaporizer assembly 400 may include a conduit structure 186, a non-nicotine vaporizer 180 including a dispensing interface 180-W and a heating element 180-H, an electrode structure 172, and an outlet conduit structure 176. The conduit structure 186 has an inner surface 186-s that at least partially defines a conduit 174 that extends through the non-nicotine vaporizer assembly 400 along its longitudinal axis 401. The conduit structure 186 may further include a set of slots 388 extending coaxially with the longitudinal axis 401 and configured to structurally support the dispensing interface 180-W and hold the dispensing interface 180-W in a fixed position relative to the conduit structure 186. As shown, the interface between the conduit structure 186 and the outer housing 130 may be sealed with a ring gasket 316.

[0098] As shown, the dispensing interface 180-W may extend laterally through the conduit 174 between slots 388 that extend along opposing sides of the conduit 174. As further shown, the heating element 180-H may extend around an outer surface of the dispensing interface 180-W. As shown, the heating element 180-H may be a wire coil that is wrapped in direct contact with the dispensing interface 180-W. The dispensing interface 180-W may include one or more instances of a wicking material, sometimes referred to as a wick.

[0099] 3A-3D , the electrode structure 172 may be positioned at a first end of the conduit structure 186 by a gasket 173. The electrode structure 172 and the gasket 173 may collectively define a first end of the conduit 174 along a longitudinal axis 401. As shown, the electrode structure 172 includes a central conduit 172-i extending (“coaxially”) along the longitudinal axis 401, and a set of at least two inlet conduits 172-o extending laterally, perpendicular to the longitudinal axis 401, between the first end of the central conduit 172-i and the outside of the electrode structure 172, further outside the conduit 174. Thus, as shown at least in Figures 3C-3D, the central conduit 172-i has a first end in fluid communication with the exterior of the non-nicotine vaporizer assembly 400 via the laterally extending inlet conduit 172-o independent of the conduit 174, and an opposite, second end directly exposed to the conduit 174. The electrode structure 172 is thus configured to direct a fluid, such as air, drawn into the non-nicotine vaporizer assembly 400 from the exterior via one or more inlet conduits 172-o into the central conduit 172-i and from the central conduit 172-i to the conduit 174. The gasket 173 may include an electrically insulating material such that the gasket 173 electrically insulates the electrode structure 172 and the conduit structure 186 from one another.

[0100] As further shown in FIGS. 3C-3D, the non-nicotine vaporizer assembly 400 includes a set of two electrical leads 181 (only one electrical lead 181 is shown in FIGS. 3C-3D, but both electrical leads 181 are shown in FIG. 6B) connected to opposite ends of the heating element 180-H. One electrical lead 181 connected to one end of the heating element 180-H may be connected to the electrode structure 172 and may extend thereto through a portion of the gasket 173, via a portion of the conduit 174. Another electrical lead 181 connected to the opposite end of the heating element 180-H may be connected to the conduit structure 186 and may extend thereto through a portion of the gasket 173, via a portion of the conduit 174. As a result, the electrical leads 181 may electrically couple the opposite ends of the heating element 180-H to the electrode structure 172 and the conduit structure 186, respectively. The gasket 173 may include an electrically insulating material such that the leads 181 extending through the gasket 173 are electrically insulated from one another and the electrode structure 172 and the conduit structure 186 may further be electrically insulated from one another. Thus, the electrode structure 172 may be configured to be an anode or cathode and the conduit structure 186 may be configured to be the opposite (e.g., cathode or anode). As shown in FIG. 1C, the lower surface 186-H of the conduit structure 186 may be configured to contact a portion of the power supply assembly 210 when the non-nicotine vapor generation assembly 110 is coupled to the power supply assembly 210. In particular, the lower surface 186-H of the conduit structure 186 is configured to contact the connector assembly 232 of the power supply assembly 210 when the non-nicotine vapor generation assembly 110 is coupled to the power supply assembly 210 at the same time that the surface of the electrode structure 172 contacts the electrode structure 230 of the power supply assembly 210. Thus, the non-nicotine vaporizer assembly 400 is configured to establish an electrical circuit extending therethrough when the non-nicotine vapor generating assembly 110 is coupled to the power supply assembly 210, the electrical circuit extending from the power supply 220 through the control circuit 222 to the electrode structure 230, and from the electrode structure 230 to the electrode structure 172 in contact with the electrode structure 230.This comprises: from the electrode structure 172 via a first electrical lead 181 in contact with both the first end of the heating element 180-H and the electrode structure 172 to a first end of the heating element 180-H, through the heating element 180-H from the first end to its opposite second end, from the second end of the heating element 180-H to the conduit structure 186 via a second electrical lead 181 in contact with both the second end of the heating element 180-H and the conduit structure 186, and from the conduit structure 186 through at least the connector assembly 232 to the power source 220.

[0101] 3A-3D, the non-nicotine vaporizer assembly 400 includes a sheath structure 178 surrounding a first end of the electrode structure 172, which is isolated from the conduit 174 by at least the gasket 173 and the conduit structure 186. The sheath structure 178 extends coaxially with the electrode structure 172 to surround the first end of the electrode structure 172, and defines an annular inlet conduit 178-i that extends coaxially with the longitudinal axis 401 and is defined by the gasket 173, the conduit structure 186, the inner surface of the sheath structure 178, and the outer surface of the electrode structure 172, as shown in FIGS. 3C-3D. As shown, the inlet conduit 178-i is open to the outside of the non-nicotine vaporizer assembly 400 and is further open to the inlet conduit 172-i of the electrode structure 172. Thus, the non-nicotine vaporizer assembly 400 is configured to direct fluid, such as air, drawn into the non-nicotine vaporizer assembly 400 via the inlet conduit 178-i and into the inlet conduit 172-i. The sheath structure 178 further protects the electrode structure from shocks at least partially perpendicular to the longitudinal axis 401, thereby improving the durability of the non-nicotine vaporizer assembly 400.

[0102] 3A-3D, the non-nicotine vaporizer assembly 400 includes an outlet conduit structure 176 that defines a longitudinal end of the outlet conduit 176-i and the conduit 174. The non-nicotine vaporizer assembly further includes an outer housing 320 that extends coaxially with the longitudinal axis 401 between a surface of the conduit structure 186 and the outlet conduit structure 176.

[0103] Referring initially to the outer housing 320, the outer housing 320 includes first ports 320-o extending therethrough and spaced apart on opposite sides of the outer housing 320 (e.g., offset 180 degrees from each other). The outer housing 320 further includes second ports 320-i extending therethrough and spaced apart on opposite sides of the outer housing 320 (e.g., offset 180 degrees from each other), where the first ports 320-o and the second ports 320-i are orthogonal to each other around the outer housing 320 (e.g., the second ports 320-i and the first ports 320-o are offset 90 degrees from each other). As shown, the inner surface of the outer housing 320 and the outer surface of the conduit structure 186 define inner and outer radial boundaries of an annular conduit 321 that extends coaxially with respect to the longitudinal axis 401 between a surface of the conduit structure 186 and the outlet conduit structure 176. Each of the first port 320-o and the second port 320-i may establish fluid communication between the dispensing interface 180-W and the exterior of the non-nicotine vaporizer assembly 400 via the annular conduit 321. As shown at least in FIGS. 9A-9E, one or more of the ports 320-o and 320-i may be exposed to the reservoir 119 of the reservoir assembly 114, either directly or via one or more ports 132, 188-o radially aligned with one or more of the ports 320-o and 320-i. The non-nicotine vaporizer assembly 400 may be coupled to the reservoir assembly 114 such that one or more of the ports 320-o, 320-i are configured to establish fluid communication between the dispensing interface 180-W and the reservoir 119 when the isolation structure 188 rotates to expose at least the barrel conduit 188-a to the reservoir 119. Thus, the non-nicotine vaporizer assembly 400 may be configured to direct the non-nicotine pre-vapor formulation from the reservoir 119 to the dispensing interface 180-W via the annular conduit 321 via one or more ports 320-o, 320-i directly exposed at opposing ends of the dispensing interface 180-W, as shown in FIGS.

[0104] In some exemplary embodiments, the non-nicotine vaporizer assembly 400 may include an additional dispensing interface that occupies part or all of the annular conduit 321, such that the annular dispensing interface separates the dispensing interface 180-W from direct exposure to the one or more ports 320-o, 320-i (e.g., where only empty space is interposed between the dispensing interface 180-W and the one or more ports 320-o, 320-i), and the additional dispensing interface may allow the non-nicotine pre-vapor formulation to be drawn from the one or more ports 320-o, 320-i through the additional dispensing interface interior and into the dispensing interface 180-W.

[0108] 5A-5C, the inner housing 130 includes protruding structures 510 extending partially around the inner surface 130-s of the inner housing 130 and radially spaced apart to define one or more longitudinal conduits 512, each longitudinal conduit 512 extending coaxially with the longitudinal axis 201 between adjacent protruding structures 510.

[0115] Now referring to at least Figures 6A-9E, when the non-nicotine vaporizer assembly 400 is inserted into the reservoir assembly 114 to at least partially occupy the conduits 188-i, 188-a, the interlock structure 410 can be configured to establish a bayonet connection between the non-nicotine vaporizer assembly 400 and the reservoir assembly 114 based on interaction of the interlock structure 410 with the conduits 512, 520 of the reservoir assembly connector assembly 550. As shown in FIGS. 6A-8C, the non-nicotine vaporizer assembly 400 may be inserted into the reservoir assembly 114 through the connector assembly 142 and into the conduits 188-i, 188-a, such that the connector structure 412 is radially aligned with the separate respective conduits 512 of the connector assembly 550 such that the projector structure 412 moves coaxially with respect to the longitudinal axis 201 and through the separate respective conduits 512 and into the separate respective conduits 520 when the non-nicotine vaporizer assembly 400 is inserted.

[0116] 8A-9E, when the non-nicotine vaporizer assembly 400 is inserted longitudinally into the reservoir assembly 114 such that the connector structures 412 are inserted longitudinally into the respective conduits 520 via the conduits 512, the non-nicotine vaporizer assembly 400 may be rotated about the longitudinal axis 201 (which may be aligned with the longitudinal axis 401 as being the same longitudinal axis upon insertion of the non-nicotine vaporizer assembly 440 into the reservoir assembly 114) such that the connector structures 412 move away from the respective conduits 520 in respective arcs about the longitudinal axis 201, through the respective conduits 520, and abut against respective structures 514 that restrict further movement of the projector structure 412 away from the respective conduits 512 that open directly into the respective conduits 520 in which the connector structures 412 are disposed. Such movement of the connector structure 412 to abut against the respective separate structures 514 may correspond to the non-nicotine vaporizer assembly 400 being rotated about the longitudinal axis 201 to radially align one or more sets of ports 320-o, 320-i with the ports 132.

[0117] As shown in at least FIGS. 6A-6C, each of the projector structures 412 includes an inner portion 412-i that is longitudinally aligned with the ring structure 414 and an outer portion 412-o that projects radially from the ring structure 414. Referring back to FIGS. 7A-9E, the connector structure 412 is configured to be inserted into and move through the conduit 520 such that the inner portion 412-i is within the inner annular conduit 520-i of a given conduit 520 and the outer portion 412-o is within the outer annular conduit 520-o of a given conduit. Additionally, the connector structure 412 may be configured such that when the connector structure 412 is moving through the conduit 520, the outer portion 412-o is constrained to move through the outer annular conduit 520-o and the inner portion 412-i is constrained to move through the inner annular conduit 520-i.

[0118] 8A-9E, the non-nicotine vapor generating assembly 110 is configured such that the isolation structure 188 can rotate about the longitudinal axis 201 such that the protrusion structure 490 can move through the inner annular conduit 520-i to selectively obstruct the inner annular conduit 520-i between the structure 514 and the conduit 512, isolating at least an inner portion 412-i of the connector structure 412 impinging against the structure 514 from the conduit 512. As a result, the protrusion structure 490 can restrict at least a portion of the interlock structure 410 (the inner portion 412-i) from disengaging from the bayonet connection defined by the conduits 512, 520 based on the protrusion structure 490 obstructing at least a portion of the conduit and / or series of conduits that may be moved to disengage the non-nicotine vaporizer assembly 400 from the reservoir assembly 114.

[0119] 8A-9E, the isolation structure 188 is configured to expose at least the inner annular conduit 520-i to the conduit 512 and isolate the barrel conduit 188-a from the one or more ports 132 based on the isolation structure 188 being in a radially offset position from the one or more ports 132. Thus, the reservoir assembly 114 can be configured such that the non-nicotine vaporizer assembly 400 is removably coupled to the reservoir assembly 114 via engagement of the interlock structure 410 and the connector assembly 550 such that the one or more connector structures 412 move through the set or sets of conduits 512, 520 to impact the structure 514 based on the isolation structure 188 being in a first position that isolates the reservoir 119 from the non-nicotine vaporizer assembly 400 and the isolation structure 188 being in a position that does not isolate the conduit 520. The isolation structure 188 isolates the reservoir 119 from the non-nicotine vaporizer assembly 400, and the isolation structure 188 does not isolate the conduits 520, 512 from each other, allowing the non-nicotine vaporizer assembly 400 to be inserted longitudinally into the reservoir assembly 114 such that the connector structure 412 of the interlocking structure 410 of the non-nicotine vaporizer assembly 440 can move through the conduit 520 and the conduit 520 open to the conduit 512 and rotate about the longitudinal axis 201 to abut the structure 514 such that one or more ports 320-o, 320-i of the non-nicotine vaporizer assembly 400 are radially aligned with one or more ports 132 when the one or more projector structures 412 abut the separate respective structures 514.

[0120] As further shown in Figures 8A-9E, the reservoir assembly 114 may be configured such that the isolation structure 188 can restrict the non-nicotine vaporizer assembly 400 from detaching from the reservoir assembly 114. This is based on the isolation structure 188 being in a second position that radially aligns its one or more ports 188-o with the one or more ports 132 of the inner housing 130. It is also based on the one or more ports 320-o, 320-i of the non-nicotine vaporizer assembly 400. The isolation structure 188 exposes the non-nicotine vaporizer assembly 400 to the reservoir 119, and the isolation structure 188 also obstructs a portion of the inner annular conduit 520-i between the connector structure 412 (impinging the structure 514) and the conduit 512. Thereby, it restricts the connector structure 412 from moving through the conduit 520 to the conduit 512 and therethrough to the outside of the reservoir assembly 114. This restricts the interlock structure 410 from disengaging from the reservoir assembly 114 when the conduit 188-a, and thus the non-nicotine vaporizer assembly 400 held therein, is exposed to the reservoir 119 via one or more ports 188-o and one or more radially aligned ports 132.

[0121] Thus, the isolation structure 188 may be configured to partially or completely mitigate leakage of the non-nicotine pre-vapor formulation from the reservoir 119 to the outside of the reservoir assembly 114 when the non-nicotine vaporizer assembly 400 is not coupled to the reservoir assembly 114. The isolation structure 188 is configured to isolate the reservoir 119 from the space 188-a into which the non-nicotine vaporizer assembly 400 is configured to be inserted based on the non-nicotine vaporizer assembly 400 being in a first position configured to allow the non-nicotine vaporizer assembly 400 to be removably engaged with the reservoir assembly 114. This is configured to restrict the non-nicotine vaporizer assembly 400 from being disengaged from the reservoir assembly 114. Furthermore, the isolation structure 188 is configured to expose the non-nicotine vaporizer assembly 400 and the reservoir 119 based on the non-nicotine vaporizer assembly 400 being in a second position for inserting the non-nicotine vaporizer assembly 400. The isolation structure 188 restricts the non-nicotine vaporizer assembly 400 from being moved out of the reservoir assembly 114. This is based on the isolation structure 188 isolating a portion of the conduit 520 from an adjacent conduit 512, restricting the non-nicotine vaporizer assembly 400 from rotating around the longitudinal axis 201, thereby restricting the connector structure 412 of the interlock structure 410 of the non-nicotine vaporizer assembly 400, which abuts the structure 514, from moving through their respective channels into their respective conduits 512 (obstructed by the respective interlock structures 491 of the isolation structure 188).

[0122] In view of the above, it will be appreciated that the reservoir assembly connector assembly 550 is configured to removably couple to the non-nicotine vaporizer assembly 400 such that fluid communication between the non-nicotine vaporizer assembly 400 and the reservoir defined by the reservoir assembly 114 is established based on a connector element of the non-nicotine vaporizer assembly 400 engaging with a connector conduit 555 of the non-nicotine vaporizer connector assembly, where the connector element may be at least the connector structure 412 of the interlock structure 410 of the non-nicotine vaporizer assembly 400. It will be further appreciated that the reservoir assembly 114 may include an isolation structure 188 configured to move between the first positions shown in FIGS. 9A-9E relative to both the reservoir assembly 114 and the reservoir assembly connector assembly 550. The isolation structure 188 exposes the non-nicotine vaporizer assembly 400 to the reservoir 119 and at least partially obstructs a connector conduit defined by the at least one conduit 512 and the conduit 520 in communication with the at least one conduit 512 to restrict the connector element from disengaging from the connector conduit 520. The second position, shown in Figures 8A-8C, is a position in which the isolation structure 188 isolates the non-nicotine vaporizer assembly 400 from the reservoir 119 and opens the connector conduit 555 to allow the connector element to disengage from the connector conduit 555.

[0123] 8A-9E, the reservoir assembly 114 may include a first fluid port, port 132, extending through the inner housing 130 of the reservoir assembly 114, the isolation structure 188 may be configured to expose the reservoir 119 to the non-nicotine vaporizer assembly 400 via the first fluid port 132 upon movement to the first position, and the isolation structure 188 may be further configured to cover the first fluid port 132, thus isolating the non-nicotine vaporizer assembly 400 from the reservoir 119 upon movement to the second position. It will also be understood that in some exemplary embodiments, the inner housing 130 may be omitted from the reservoir assembly 114 such that the first fluid port 132 is also omitted.

[0124] As shown in at least FIGS. 2C-2D , the reservoir assembly 114 may include a second fluid port 150-i configured to allow fluid communication between the reservoir 119 and the exterior of the non-nicotine vapor generation assembly 110. The isolation structure 188 may be configured to cover the second fluid port 150-i to isolate the reservoir 119 from the exterior of the non-nicotine vapor generation assembly 110 based on movement to the first position. The isolation structure 188 provides isolation of the reservoir from the exterior based on movement to the second position. The isolation structure 188 may further be configured to expose the second port 150-i to expose the reservoir 119 to the exterior of the non-nicotine vapor generation assembly 110 based on movement to the second position. The reservoir assembly 114 may be configured to be refilled via the second fluid port 150-i based on the isolation structure 188 being in the second position.

[0125] In some exemplary embodiments, the isolation structure 188 may be configured to move relative to both the reservoir assembly 114 and the reservoir assembly connector assembly 550 to a third position in which the isolation structure covers both the first fluid port and the second fluid port, and the isolation structure 188 is also configured to open the connector conduit 555 so that the connector element can disengage from the connector conduit 555 based on the isolation structure 188 moving to the third position.

[0126] In some illustrative embodiments, the isolation structure 188 may include a third fluid port 188-o configured to at least partially align with the first fluid port 132 such that the isolation structure 188 exposes the first fluid port 132 based on the isolation structure 188 moving to the first position.

[0127] It will also be understood that in some exemplary embodiments, the second fluid port 150-i, the coupling structure 160, the third fluid port 160-i, and / or the port adjustment ring 116 may be omitted from the reservoir assembly 114.

[0128] 5A-5B, the reservoir assembly connector assembly 550 may be a bayonet connector configured to establish a bayonet interface connection with a bayonet connector, such as the interlocking structure 410 of the non-nicotine vaporizer assembly 400. However, in some exemplary embodiments, the reservoir assembly connector assembly 550 may be configured to establish a different connection with the non-nicotine vaporizer assembly 400, including a threaded connection.

[0129] As shown in FIGS. 7A-9E, the isolation structure 188 may be configured to rotate about a longitudinal axis 201 to move between a first position and a second position.

[0130] While a number of exemplary embodiments are disclosed herein, it should be understood that other variations are possible.
