The disclosures of the foregoing applications are incorporated herein by reference in their entirety. Technical Field

[0002] The subject matter described herein relates to steam generator devices, including steam generator devices comprising a steam generator body configured to heat a casket containing evaporable material. Background Technology

[0003] Vaporizer devices (also referred to as vaporizers, electronic vaporizer devices, or e-vaporizer devices) are used to deliver an aerosol containing one or more active ingredients by inhalation by a user. This delivery method involves the user inhaling the aerosol (e.g., a gaseous and / or condensed material suspended in air or other gaseous carriers, whether at rest or in motion). For example, electronic nicotine delivery systems (ENDS) include a class of vaporizer devices that are battery-powered and can be used to simulate the smoking experience without burning tobacco or other substances. Vaporizer devices are increasingly popular for prescription medical use, drug delivery, and the consumption of tobacco, nicotine, and other botanical materials. Vaporizer devices can be portable, self-contained, and / or easy to use.

[0004] In the use of a vaporizer device, the user inhales an aerosol (commonly known as "vapor"), which may be generated by a heating element that evaporates (e.g., causes at least part of a liquid or solid to change into a gaseous phase) an evaporable material (which may be a liquid, solution, solid, paste, wax, and / or any other form compatible with a particular vaporizer device). The evaporable material used with the vaporizer device may be housed within a casing (e.g., a separable portion of the vaporizer device that contains the evaporable material), which includes an outlet (e.g., a mouthpiece or an outlet in fluid communication with a mouthpiece) for the user to inhale the aerosol.

[0005] In order to receive the inhalable aerosol generated by the vaporizer device, in some examples, the user may activate the vaporizer device by inhalation, by pressing a button, and / or by some other method. As used herein, inhalation may refer to a user drawing a volume of air into the vaporizer device so that it is inhaled through the combination of the air with the vaporizing material (e.g., a gaseous material) to generate an inhalable aerosol.

[0006] The method by which a vaporizer device generates an inhalable aerosol from an evaporable material involves heating the evaporable material (e.g., in a housing, insert, evaporation chamber, heating chamber, oven, and / or compartment associated with a heating element) to cause at least a portion of the evaporable material to be converted into an evaporated material (e.g., a gaseous material). An evaporation chamber, heating chamber, oven, or the like can refer to an area or volume within the vaporizer device in which a heat source (e.g., a conductive, convective, and / or radiant heat source) causes heating of the evaporable material to generate an evaporated material and allows the evaporated material to mix with air to form an aerosol for inhalation by a user of the vaporizer device.

[0007] The steam generator device may be controlled by one or more controllers, electronic circuits (e.g., sensors, heating elements, buttons, switches) and / or the like on or in the steam generator device. The steam generator device may also communicate wirelessly with an external controller (e.g., a computing device such as a personal computer or smartphone).

[0008] In some implementations, the casing containing the solid evaporable material (e.g., plant materials such as tobacco leaves and / or portions thereof) must be heated to undesirable high temperatures so that the inner region of the evaporable material is heated to the minimum temperature required for evaporation. Consequently, portions of the solid evaporable material contained within the casing may burn or char at these high temperatures, producing combustion or partial combustion byproducts (e.g., chemical elements or compounds) that may have undesirable properties, such as unpleasant odors or tastes, adverse health effects, etc. Furthermore, due to the low thermal conductivity of some evaporable materials (e.g., plant materials such as tobacco), achieving uniform heating of the evaporable material in current conduction-based vaporizers can be difficult. Therefore, controlled and uniform heat distribution is desirable in such devices.

[0009] Some problems with current vaporizer devices include the inability to efficiently and effectively heat evaporable materials without wasting significant amounts of energy. For example, some vaporizer devices include a heater body surrounding the tobacco consumable, which requires heating the entire heater body to create an oven. This configuration requires additional energy to maintain sufficiently high temperatures in areas exposed to the airflow, thereby losing at least some of the heat generated by the heater that could have been used to heat the tobacco material. Consequently, energy may be wasted due to the inefficient use of the generated heat.

[0010] Vaporizer devices configured to embed some or part of the heating element within the tobacco material may include an airflow through the tobacco material, thereby preventing the tobacco from becoming tightly compacted around the heater and thus reducing heat transfer from the heater to the tobacco material. Furthermore, vaporizer devices with a heater element embedded within or at least partially surrounded by tobacco may also experience cleaning and hygiene issues. For example, when the heater punctures the tobacco, residue may remain on the heater element after use, requiring the user to clean the heater element before continued use. Summary of the Invention

[0310] In some implementations, winding the heating assembly onto the evaporable material may include: attaching a first edge portion of the substrate to a second edge portion of the substrate opposite to the first edge portion; and attaching first edge segments of a plurality of heating elements to second edge segments of the plurality of heating elements opposite to the first edge segments. In such implementations, the first edge segments of the plurality of heating elements may extend over the first edge portion of the substrate. In some implementations, the second edge segments of the plurality of heating elements may extend over the second edge portion of the substrate.

The heating assembly includes: a first support substrate and a first plurality of heating elements disposed on a first surface of the first support substrate; and a second support substrate and a second plurality of heating elements disposed on a first surface of the second support substrate. The first plurality of heating elements extends at least partially between two opposite sides of the first support substrate. The second plurality of heating elements extends at least partially between two opposite sides of the second support substrate.

[0314] In some implementations, the second plurality of heating elements may extend from a first side of the two opposing sides of the second plurality of heating elements to a second side of the two opposing sides.

[0316] In some implementations, when the first support substrate comes into contact with the second support substrate, at least a portion of the first surface of the first support substrate may face at least a portion of the first surface of the second support substrate.

[0317] In some implementations, when the first support substrate comes into contact with the second support substrate, the first support substrate and the second support substrate can be combined to form a continuous ring.

[0318] In some implementations, when the first support substrate contacts the second support substrate, a corresponding first segment of the first plurality of heating elements can be positioned and contact a corresponding first segment of the second plurality of heating elements, and a corresponding second segment of the first plurality of heating elements can be positioned and contact a corresponding second segment of the second plurality of heating elements.

[0319] In some implementations, the heating assembly may include an auxiliary substrate, wherein at least the first support substrate, the second support substrate, or both are coupled to the surface of the auxiliary substrate. In some implementations, the auxiliary substrate may be paper.

[0321] In some implementations, the first heating element in the first plurality of heating elements may be separated from the second heating element in the first plurality of heating elements by a distance, and the first heating element in the second plurality of heating elements may be separated from the second heating element in the second plurality of heating elements by a distance.

[0322] In some implementations, when the first support substrate comes into contact with the second support substrate, at least a portion of the first surface of the first support substrate may face at least a portion of the first surface of the second support substrate.

[0323] In some implementations, when the first support substrate comes into contact with the second support substrate, the first support substrate and the second support substrate can be combined to form a continuous ring.

For instance, by providing multiple inductors, a single wound heating stage, and / or a feedback loop with sensors, localized heat transfer can be controlled during use (e.g., each complete use of the chamber, from start to finish, referred to herein as the evaporation period).

[0330] An additional benefit that can be provided by the various implementations of the vaporizer device described herein is improved contact between the heating element and / or heated surface of the heating system and the housing containing the evaporable material, ensuring efficient and effective heat transfer between the heating element and the evaporable material. For example, by maintaining close contact between the housing and the heating element and / or heated surface, heat loss (e.g., to the surrounding housing of the vaporizer device) can be reduced, and heating efficiency (e.g., power consumption per unit of power) can be increased. An additional benefit that can be provided by the various implementations of the vaporizer device described herein is increased user satisfaction. For example, in some implementations, appropriate mixing of relatively cool air (e.g., ambient temperature air) with heated air containing the evaporable material can improve the formation of submicron-sized aerosol particles, thereby reducing the condensation of one or more compounds released during the heating of the evaporable material onto the inner surfaces of the vaporizer device (e.g., the suction tube and / or mouthpiece). Such condensate may ultimately be drawn into the user's mouth in liquid form, resulting in an unpleasant taste and making it unusable for inhalation, thereby reducing the amount of inhalable product available. Therefore, by ensuring proper mixing and aerosol generation, the current implementation of the topic can increase user satisfaction.

[0331] In some implementations, the evaporable material may be placed in a location that is in direct contact with and / or close proximity to the heating element of the heating system to allow for efficient and effective heat transfer from the heating element to the evaporable material. In some implementations, a housing including the heating element and the evaporable material (e.g., evaporable material housed within a suitably configured structure) may be placed within a vaporizer body configured to transfer energy to the heating element, such as through one or more inductors and / or by completing a circuit containing the heating element. In other implementations, a housing including the evaporable material (e.g., evaporable material housed within a suitably configured structure) may be placed within an evaporation chamber, heating chamber, oven, or the like, in which case the area or volume within the vaporizer body where the heating element causes heating of at least a portion of the evaporable material comprises the internal area or volume of the housing. The characteristics of a suitably configured structure include: being at least partially formed of a metal and / or some other material that is durable under heating and has sufficient thermal conductivity; one or more openings through which air can enter the housing to facilitate heating the evaporable material and / or transfer the evaporable material during evaporation; one or more openings through which ambient air mixes with the evaporated material to form at least a portion of an inhalable aerosol; delivery of the inhalable aerosol out of the housing; and / or the like. Thus, compared to some currently available vaporizer devices, the vaporizer device, heating system, housing, and evaporable material described herein provide more efficient heating of the evaporable material and formation of inhalable aerosols. Other benefits are described herein and are within the scope of this disclosure. It will be understood that aerosol formation can occur simultaneously with (e.g., immediately after) the evaporation of the evaporable material, such as based on air present in or near the evaporable material, and the provision of ambient air can accelerate the formation of inhalable aerosols.

[0332] As used in the following description and claims, the term "vaporizer device" refers to any of the following: a self-contained device, a device comprising two or more separable parts (e.g., a vaporizer body comprising a battery and other hardware, a cartridge and / or insert comprising vaporizable material, and / or a mouthpiece configured to deliver an inhalable aerosol to a user (including the mouthpiece portion comprising the cartridge)), and / or the like. As used herein, a "vaporizer system" may comprise one or more components, such as a vaporizer device, a charger for charging the vaporizer device, a wired or wireless communication device communicating with the vaporizer device, a remote server communicating with the communication device, and / or the like. Examples of vaporizer devices consistent with implementations of the present subject include electronic vaporizers, electronic nicotine delivery systems (ENDS), and / or the like. Such vaporizer devices may be handheld devices that heat (e.g., by convection, conduction, radiation, induction, and / or a combination thereof) vaporizable material to deliver an inhalable dose of material to a user. Vaporizer devices can be considered as “generating” inhalable aerosols because they provide the capability and / or functionality (e.g., heat, airflow path, condensation chamber, etc.) required to convert evaporable materials into inhalable aerosols.

[0333] The evaporable material used with the steam generator device may optionally be disposed within a housing (e.g., an insertable and removable portion of the steam generator device that contains the evaporable material), which can be refilled when empty or is disposable, allowing for the use of new housings containing additional evaporable materials of the same or different types. The steam generator device may be a steam generator device using a housing, a housing-less steam generator device, or a multipurpose steam generator device that can be used with or without a housing. Some housing implementations may contain evaporable material, which may be stacked to an appropriate density as described herein. In some implementations, the steam generator device may include a compartment (e.g., a reservoir, a heating chamber, and / or the like) configured to directly receive the housing therein and heat the evaporable material to form an inhalable aerosol.

[0334] In some implementations, the vaporizer device may be configured for use with liquid evaporable materials (e.g., a carrier solution in which active and / or inactive components are suspended or retained in solution, or the evaporable material itself in liquid form) and / or non-liquid evaporable materials (e.g., pastes, waxes, gels, solids, plant materials, and / or the like). Non-liquid evaporable materials may comprise plant materials that release a portion of the plant material as evaporable material (e.g., a portion of the plant material remains as waste after the evaporated material is inhaled by the user), or optionally may be in solid form, such that all solid material can ultimately be evaporated for inhalation. Liquid evaporable materials may similarly be capable of complete evaporation or may be comprised of a portion of the liquid material remaining after all material suitable for inhalation has evaporated.

[0335] The evaporable material can be implemented in part by being made of non-liquid evaporable materials, such as tobacco (e.g., leaves, stems, and / or the like), other plant matter, and / or other solids (such as cotton). In such implementations, the evaporable material also includes a wetting agent or other aerosol-forming material or carrier, such as propylene glycol, vegetable glycerin, acids (e.g., organic acids, such as benzoic acid, citric acid, etc.), and / or the like. Thus, some implementations of vaporizer devices can be configured to use evaporable materials made at least partially of one or more evaporable materials (e.g., containing one or more compounds that can be converted into a gaseous phase when the evaporable material is heated to a sufficient temperature) to heat and form an inhalable aerosol, as described in more detail herein.

[0336] Figures 1A to 1C Block diagrams depicting example vaporizer devices 100a, 100b, and 100c (collectively, vaporizer device 100) consistent with implementations of the present subject are shown. Vaporizer device 100 may include a power source 112 (e.g., a battery, which may be a rechargeable battery) and a controller 104 (e.g., a processor, circuitry, etc. capable of executing logic) for controlling heat delivery from one or more heating elements 142 (collectively, heating elements 142) to cause at least a portion of the evaporable material 102 of the capsule 120 (such as a solid, liquid, solution, suspension, a portion of at least partially untreated plant material, etc.) to be converted into a gaseous phase. Controller 104 may be a portion of one or more printed circuit boards (PCBs) consistent with certain implementations of the present subject.

[0337] After a certain amount of one or more compounds present in the evaporable material 102 is converted into a gaseous phase, at least some of those gaseous compounds are condensable to form particulate matter in at least partial local equilibrium with the gaseous phase as part of an aerosol, which can form some or all of the inhalable dose provided by the vaporizer device 100 during aspiration or inhalation by a user on the vaporizer device 100. It should be understood that the interaction between the gaseous and condensed phases in the aerosol produced by the vaporizer device 100 can be complex and dynamic due to factors such as temperature (e.g., ambient or local temperature at various points within the vaporizer device and / or housing), relative humidity, chemical properties, vapor pressure of one or more evaporable compounds, flow conditions in the airflow path (both inside the vaporizer device 100 and in the respiratory tract of humans or other animals), and / or mixing of one or more compounds in the gaseous or aerosol phase with other airflows, which can affect one or more physical parameters of the aerosol. In some vaporizer devices, and specifically for vaporizer devices configured to deliver relatively volatile compounds, the inhalable dose may be primarily in the gas phase (e.g., the formation of condensed particles may be very limited).

[0338] Heating element 142 may comprise one or more of a conductive heater, a radiant heater, an induction heater, and / or a convection heater. One type of heating element 142 is a resistance heating element, which may comprise a material (such as a metal or alloy, e.g., a nickel-chromium alloy or a non-metallic resistor) configured to dissipate electrical energy in the form of heat when an electric current travels through one or more resistive segments of the resistance heating element. Another type of heating element 142 is a heating stage, which may comprise a material (such as a metal or alloy, e.g., an aluminum alloy and / or a ferrite material, such as a stainless steel alloy) configured to absorb energy and convert it into heat when magnetic and / or electromagnetic energy is radiated to one or more segments of the heating stage. In various implementations of the present subject matter, heating element 142 (e.g., a resistance heating element, a heating stage, and / or the like) is configured to generate heat to convert one or more compounds present in the evaporable material 102 into a gaseous phase to produce an inhalable dose of one or more compounds present in the evaporable material 102. As described herein, in some implementations, the evaporable material 102 comprises a non-liquid evaporable material, including, for example, a solid material (such as a gel, wax, or the like) or a plant material (e.g., tobacco leaves and / or tobacco stems).

[0339] In some implementations, the heating element 142 may be part of the housing 120 (e.g., part of a disposable portion of the steam generator 100), such as Figure 1A The steam generator apparatus 100a is shown. As illustrated, the housing 120 may include: a suction nozzle portion 130, which includes one or more inserts 124 (e.g., one or more filters, such as those used for steam extraction). Figure 1A and Figure 1B An example implementation of insert 124 is illustrated; and a heater portion 141 includes evaporable material 102 and one or more heating elements 142. In some implementations, nozzle portion 130 can be releasably coupled to a portion of housing 120. In some implementations, nozzle portion 130 can be integrated with housing 120. In some implementations, nozzle portion 130 may include one or more elements of housing 120 (e.g., airflow path, insert, end cap, evaporable material, etc.), as described herein.

[0340] In some implementations, the housing 120 may include one or more inserts 124, and each insert 124 may include one or more filters and / or filter materials. For example, one or more inserts 124 may be made of a vapor-impermeable and / or moisture-resistant (e.g., at least to some extent resistant to the destructive effects of water) material. Such materials may include one or more of the following: metals, metal alloys, cotton, paper materials (such as cardboard), corrugated materials (such as cardboard or paper), tobacco paper, heat-resistant plastics (such as polyethylene terephthalate (PET)), cellulose acetate, non-wood plant fibers (such as flax, sisal, straw, and / or Spanish grass), and / or similar materials. In some implementations, at least a portion of the insert 124 may be inserted into and / or surrounded by one or more elements, including one or more elements associated with the housing 120 and / or the vaporizer body 110. For example, one or more inserts 124 may be positioned adjacent to a divider (e.g., Figure 4G The separator 454) and end cap (e.g., Figure 6B The end cap 664 is one or more of the elements in the housing 120, in contact with and / or offset from the elements (e.g., along the length of the housing 120 as used and defined herein) as described herein. In some implementations, at least a portion of the insert 124 may be exposed (e.g., not inserted into or surrounded by one or more elements), including the entire length of the insert 124 (as used and defined herein) may be exposed. As used herein, "end cap" may designate at least one of various materials and / or elements located adjacent to one end of the housing 120 (such as a first or second end of the housing 120). In some implementations, the end cap may be positioned at one end of the housing 120. In some implementations, the end cap may be positioned offset from one end of the housing 120 (e.g., along the length of the housing 120), including a distal or proximal element not present as along the length of the housing 120. For example, the end cap may form part of the outer surface of the housing 120 and / or the end cap may be completely contained within the outer surface of the housing 120.

[0341] In some implementations, heater portion 141 may optionally include one or more inserts 124 at an end of the evaporable material 102 (e.g., the distal end of housing 120) to help retain the evaporable material 102 within housing 120. The one or more inserts 124 may have multiple openings, such as inlets, channels, and / or outlets. In some implementations, at least a portion of the one or more inserts 124 may be permeable, allowing vapor and / or aerosols to travel through the inserts 124. In some implementations, heater portion 141 can be releasably coupled to a portion of housing 120. In some implementations, heater portion 141 may be integrated with housing 120. In some implementations, heater portion 141 may include one or more elements of housing 120 (e.g., airflow paths, inserts, evaporable material, etc.), as described herein. In some implementations, heater portion 141 may include more than one separable and / or releasably coupled portion. For example, a portion of the heating section 141 may be integrated with the housing 120, and a second portion of the heating section 141 may be integrated with or outside the housing 120, such as with the steam generator body 110.

[0342] The nozzle portion 130 and the heater portion 141 can be connected via an outer layer (such as one or more material layers, e.g., covering material 122, such as by...) Figure 1A and Figure 1B (Examples shown in the illustration) and the housing or other one or more complementary structural materials are connected together. In some implementations, the heater portion 141 may be considered as including at least a portion of the housing 120 that is insertably received in the reservoir 118, and the nozzle portion 130 may be considered as at least some of the portion of the housing 120 that remains outside the reservoir 118 when the housing 120 is insertably received in the reservoir 118. In some implementations, the reservoir 118 may be configured to be insertably received and coupled to the housing 120 via snap-fit, press-fit, friction fit, magnetic attachment and / or the like. In some implementations, the vaporizer body 110 may include a flange 121 that at least partially defines an opening in the reservoir 118. The flange 121 may include features that facilitate placement of the housing 120 into the reservoir 118, such as a chamfered edge. As used in this document, the entire mouthpiece portion 130 need not be designed to be inserted into the user's mouth, but only need to be located at or near the end of the cartridge 120 which is designed for the user to place in their mouth during use.

[0343] The heating element 142 may be wound (at least partially) around the evaporable material 102, pressed to thermally contact the evaporable material 102, or otherwise configured to deliver heat directly to the evaporable material 102 to cause the release of one or more compounds into the gas phase. Within the vaporizer body, a drive circuit system 143 for driving the heating element 142 is provided (e.g., Figure 1C (As shown in the diagram). For example, the drive circuit system 143 may include two or more electrical contacts (e.g., at least partially located within the housing 118) for providing a conductive path between the power supply 112 of the steam generator body 110 and the heating element 142 of the housing 120 when the housing 120 is insertably received within the housing 118. In other implementations, the drive circuit system 143 may include one or more inductors, such as two or more induction coils, configured to generate an electromagnetic field that is directed and positioned to affect the heating element 142 (which may take the form of a heating table) to cause the heating table to generate heat.

[0344] In other implementations, the heating element 142 may be part of the steam generator body 110 (e.g., part of a durable or reusable portion of the steam generator 100), such as Figure 1B The vaporizer device 100b is shown. As illustrated, a housing 120 may include: a suction portion 130 containing one or more inserts 124; and a container portion 123 containing evaporable material 102. The suction portion 130 and the container portion 123 may be connected together via an outer layer (such as one or more covering materials 122). A heating element 142 may be wound (at least partially) around the housing 120 containing the evaporable material 102, pressed to thermally contact the housing, or otherwise arranged to deliver heat to the housing to convert one or more compounds from the evaporable material 102 into a gaseous phase for subsequent inhalation by a user as a gaseous and / or condensed phase (e.g., aerosol particles or droplets). For example, the heating element 142 may be positioned within a reservoir 118 and arranged to directly or indirectly heat the container portion 123 (e.g., by conduction, radiation, or convection), which in turn heats the evaporable material 102 contained therein. In relevant implementations, heating element 142 may be positioned outside of container 118 and arranged to heat container 118 itself to generate an oven that provides convective and / or conductive heat. In either case, heating element 142 may be at least partially or substantially wound around the periphery of container 118. This heating element may be heated by one or more of various mechanisms, such as, for example, resistance, induction heating, chemical or combustion-related heating (e.g., by combustion or causing oxidation or other exothermic chemical conversion of fuel materials), heat conduction from another heating element, radiative heating, convection, etc.

[0345] In other implementations, the heating element 142 may be part of a casing 120 that contains liquid evaporable material 102 in a liquid reservoir 182, such as... Figure 1C The vaporizer apparatus 100c is shown. As illustrated, the housing 120 may include a suction portion 130 and a housing portion 192, the housing portion 192 containing a heater portion 141 and a reservoir 182 configured to hold liquid evaporable material 102. The suction portion 130 and the housing portion 192 may be integrally formed (e.g., manufactured as a single piece) or may be connected together via mechanical coupling members (such as snap-fit, press-fit, friction fit, adhesive, and / or the like). The heater portion 141 may include a heating element 142 and a wicking material (not shown) configured to transfer the liquid evaporable material 102 from the reservoir 182 via capillary action to contact the heating element 142. In some implementations, the heating element 142 may be in direct contact with the wicking material, such as by pressing against one or more sides of the wicking material, at least partially winding around the wicking material, and / or the like. Heating element 142 may be configured to generate heat to convert one or more compounds from evaporable material 102 into a gaseous phase for subsequent inhalation by a user as a gaseous and / or condensed phase (e.g., aerosol particles or droplets). For example, heater portion 141 may include a circuit system configured to receive an applied electromagnetic field and / or convert it into a current for powering and thereby heating heating element 142. In some implementations, heating element 142 itself may be configured to generate heat based on a structure (e.g., material and shape) having an applied electromagnetic field configured to receive it and convert it into a current for powering and thereby heating heating element 142. Thus, heater portion 141 and / or heating element 142 may be powered via drive circuit system 143, as described herein.

[0346] In cases where the evaporable material 102 comprises a non-liquid evaporable material, the heating element 142 may be a portion of the wall of the housing 120 and / or the heating chamber or compartment (e.g., the container 118) to which the evaporable material 102 is placed, or otherwise incorporated into or in thermal contact with the wall. Alternatively or additionally, the heating element 142 may be used to heat air entering, passing through, or traversing the housing 120 to result in convective heating of the evaporable material 102 (e.g., within the housing 120). In yet another example, the heating element 142 may be arranged in close contact with the evaporable material 102 such that direct conductive heating of the evaporable material 102 of the housing 120 occurs from within the bulk of the evaporable material 102, rather than solely from the wall of the heating chamber (e.g., an oven and / or the like). Convective heating of air traveling through or traversing the housing 120 may also occur in such configurations. Additionally, conductive heating may occur by induction heating of the heating element 142. That is, the heating element 142 may generate heat based on the conversion of electromagnetic energy into heat, and this heat may be conducted to other parts of the housing 120, such as, for example, other parts of the heating element 142 that are not directly affected by electromagnetic energy, the evaporable material 102, other heat-conducting parts of the housing 120, or the vaporizer body 110, etc. The evaporable material 102 may evaporate in part based on contact with one or more surfaces of the heating element 142 and / or other materials heated by the heating element 142 through this heat.

[0347] In some implementations, the evaporable material 102 may be heated via one or more heating elements 142 that are not in physical contact with the evaporable material 102, such as by convection heating. According to such implementations, the heating elements 142 may be configured to heat air traveling along, through, and / or near the heating elements 142 such that the air temperature reaches a level sufficient to evaporate at least a portion of the evaporable material 102. In some implementations, the evaporable material 102 may be evaporated by both conductive heat from at least one heating element 142 and convective heat from at least one other heating element 142.

[0348] Heating element 142 may provide heat in association with a user's suction (e.g., drawing, inhaling, etc.) at the end of the mouthpiece portion 130 and / or vaporizer device 100 to convert one or more compounds present in the evaporable material 102 into a gaseous phase, causing air to flow from an air inlet along an airflow path to facilitate the formation of an aerosol, which may be delivered through an air outlet in the mouthpiece portion 130 and inhaled by the user. The incoming air moving along the airflow path moves through (e.g., around, across, etc.) and / or through the housing 120 and / or the evaporable material 102, wherein compounds released from the evaporable material 102 into the gaseous phase are entrained into the air. Heating element 142 can be activated via controller 104, which may optionally be part of vaporizer body 110 as discussed herein, thereby causing current to travel from power source 112 through circuitry that includes heating element 142 (which may be part of vaporizer body 110) or otherwise electromagnetically coupled to heating element 142 (e.g., as part of an inductor-heating platform pairing). As mentioned herein, at least some of the entrained one or more gaseous compounds may condense as they travel through the remainder of the airflow path, such that an inhalable dose of one or more compounds in aerosol form (e.g., via mouthpiece portion 130) can be delivered from the air outlet for inhalation by the user.

[0349] In some implementations, the heating element 142 may be activated in association with user interaction with the steamer device 100. For example, activation of the heating element 142 may result from the automatic detection of suction or other user interaction based on one or more signals generated by one or more sensors 113. The one or more sensors 113 and / or the signals generated by the one or more sensors 113 may include one or more of the following: one or more pressure sensors arranged to detect pressure relative to ambient pressure along the airflow path of the steamer device 100 or optionally measure changes in absolute pressure; one or more temperature sensors, such as thermistors, positive temperature coefficient (PTC) circuits (such as PTC thermistors), negative temperature coefficient (NTC) circuits (such as NTC thermistors), thermocouples and / or the like, arranged to measure the temperature of the container 118, the heating element 142 and / or some other component of the steamer body 110 or the casing 120; one or more circuits configured, for example, based on The temperature of the heating element 142 is determined by measuring or determining the resistance and / or inductance of the heating element 142 by comparison with one or more resistors having known resistance and / or one or more inductors having known inductance; one or more motion sensors, such as accelerometers, gyroscopes, or the like, configured to detect movement, vibration, orientation, position, acceleration, etc. of the steam evaporator device 100; one or more flow sensors configured to detect the flow rate of air, gas, or liquid within the steam evaporator device 100; a capacitive sensor configured to detect touch of a part of the steam evaporator device 100, such as a user's finger, palm, lips, etc.; a circuit system configured to detect interaction with the steam evaporator device 100 via one or more input devices 116 of the steam evaporator device 100 (such as buttons, other tactile controls, or the like); a circuit system configured to receive and process signals from a computing device communicating with the steam evaporator device 100; and / or a circuit system configured to determine whether suction is occurring or about to occur.

[0350] In some implementations, the vaporizer device 100 may be configured to initiate a heating cycle that may include a period of time in which heating element 142, container 118, housing 120, and / or evaporable material 102 are heated to an operating (e.g., predetermined) temperature or temperature range (e.g., a temperature or range sufficient to convert one or more compounds present in evaporable material 102 into a gaseous phase). Once heating element 142, container 118, housing 120, and / or evaporable material 102 have reached the operating temperature or temperature range, the vaporizer device 100 may be configured to maintain or otherwise regulate the application of heat such that evaporable material 102 is evaporable without combustion. In some implementations, additional heat may be provided via heating element 142 after an event such as a user placing their lips on the vaporizer device 100, a user inhaling on the vaporizer device 100, and / or any signal described herein (e.g., generated by one or more sensors 113). The heating cycle may terminate after detecting additional interaction with the steam generator device 100 via one or more input devices 116, after determining that a certain amount of time has elapsed since the start of the heating cycle, after determining that a certain amount of time has elapsed since the last detection of user suction, after determining that the cartridge 120 is not present in the container 118, or due to other events, actions, the duration of the detection of such events and actions, and / or the like (consistent with the implementation described herein).

[0351] As discussed herein, the steam generator device 100, consistent with the implementation of the present subject matter, can be configured to connect (e.g., wirelessly or via a wired connection) to a computing device (or optionally two or more devices) communicating with the steam generator device 100. For this purpose, the controller 104 may include communication hardware 105. The controller 104 may also include memory 108. The communication hardware 105 may include firmware and / or be controlled by software for executing one or more protocols for communication.

[0352] The computing device may be a component of the steam engine system, which also includes the steam engine device 100, and may include its own communication hardware that can establish a wireless communication channel with the communication hardware 105 of the steam engine device 100. For example, the computing device used as part of the steam engine system may include a general-purpose computing device (such as a smartphone, tablet computer, personal computer, other portable device such as a smartwatch, or the like) that executes software to generate a user interface that allows a user to interact with the steam engine device 100. In other implementations of the present subject matter, this computing device used as part of the steam engine system may be a piece of dedicated hardware, such as a remote control or other wireless or wired device having one or more physical or software interface controls (e.g., configurable on a screen or other display device and selectable via user interaction with a touch-sensitive screen or other input device 116 such as a mouse, pointer, trackball, cursor button, or the like). The steam engine device 100 may also include one or more outputs 117 or devices for providing information to a user. For example, output 117 may include one or more light-emitting diodes (LEDs) configured to provide feedback to the user based on the status and / or operating mode of the vaporizer device 100. The one or more LEDs may be monochrome LEDs and / or multicolor LEDs (e.g., both may be used separately).

[0353] In examples where the computing device provides signals related to the activation of the heating element 142, or in other examples where the computing device is coupled to the vaporizer device 100 to achieve various control or other functions, the computing device executes one or more computer instruction sets to provide a user interface and low-level data processing. In one example, the computing device detects that user interaction with one or more user interface elements may cause the computing device to signal the vaporizer device 100 to activate the heating element 142 to reach the operating temperature for generating an inhalable dose of aerosol. Other functions of the vaporizer device 100 can be controlled through user interaction with the user interface on the computing device that communicates with the vaporizer device 100.

[0354] The temperature of the heating element 142 of the steam generator device 100 may depend on several factors, including the amount of electrical or energy delivered to the heating element 142, the voltage applied to the heating element 142 and / or the drive circuit system 143, the duty cycle of delivering electrical or current, the frequency of providing electrical power to the heating element 142 and / or the drive circuit system 143, the duration of delivering electrical or current, the efficiency of the heating element 142 in converting current into heat, the temperature coefficient of resistivity (TCR) of the heating element 142, the construction and geometry of the heating element 142 (e.g., thickness, number of layers, number of folds or bends, etc.), conductive and / or radiative heat transfer to other parts of the steam generator device 100 (e.g., the evaporable material 102) and / or to the environment, latent heat loss due to the evaporation of the evaporable material 102, convective heat loss due to airflow (e.g., air flowing through the heating element 142 and / or the area heated by the heating element 142 when a user draws air onto the steam generator device 100), and / or the like.

[0355] As mentioned herein, in order to reliably activate the heating element 142 and / or heat it to a desired temperature, in some implementations of the present subject matter, the vaporizer device 100 may utilize signals from one or more sensors 113. For example, the one or more sensors 113 may include pressure sensors and / or airflow sensors to determine when a user inhales. The one or more sensors 113 may optionally be located in and / or connected (e.g., via a passage or other path) to an airflow path containing an airflow inlet for air to enter the vaporizer device 100 and an airflow outlet for the user to inhale the resulting aerosol, such that the one or more sensors 113 experience a change (e.g., a pressure change) as the air travels from the airflow inlet through the vaporizer device 100 to the airflow outlet. In some implementations of the present subject matter, the heating element 142 may be activated in association with a user's inhalation, for example by automatically detecting inhalation, or by detecting changes in the airflow path (such as pressure changes or flow rates) by one or more sensors 113.

[0356] Alternatively or additionally, in order to maintain the heating element 142 at the desired temperature, in some implementations of the present subject matter, the steam generator device 100 may utilize additional signals from one or more sensors 113. For example, one or more sensors 113 may include capacitive, conductive, and / or electromagnetic sensors to determine the inductance, resistance, and / or impedance of the heating element 142. One or more sensors 113 may optionally be located in a position physically in contact with the heating element 142 (e.g., within the housing 118) or located sufficiently close to the heating element 142 to measure changes in the electromagnetic field affecting the heating element (e.g., within at least a portion of the housing 118, touching or approaching at least a portion of the housing 118). In some implementations, one or more sensors 113 may be in electrical communication with an inductor configured to sense heating of the heating element 142 and / or configured to determine the inductance, resistance, and / or impedance of the inductor. Alternatively or additionally, one or more sensors 113 may include a temperature sensor configured to sense the temperature of the inductor and / or the heating element 142. Based on information derived from one or more sensors 113, controller 104 may be configured to estimate the temperature of heating element 142, as described herein. In some implementations, heating element 142 may be activated and / or the power supplied to heating element 142 may be adapted in relation to the estimated temperature of heating element 142, for example by comparing the inductance and / or resistance of heating element 142 detected via one or more sensors 113 with suitable sensing circuitry.

[0357] One or more sensors 113 may be positioned on and / or coupled to (e.g., an electrical or electronic connection, physically or via a wireless connection) the controller 104. For accurate measurements and to maintain the robustness of the steam generator 100, it is advantageous to provide a seal with sufficient flexibility to separate the airflow path from other parts of the steam generator 100. The seal (which may be a gasket) may be configured to at least partially surround one or more sensors 113, such that the connection of one or more sensors 113 to the internal circuitry of the steam generator 100 is isolated from a portion of the one or more sensors 113 exposed to the airflow path. Such an arrangement of seals in the steam generator 100 can help mitigate the potential destructive effects on steam generator components caused by interactions with environmental factors such as water in a gaseous or liquid phase and / or reduce air escape from designated airflow paths within the steam generator 100. Air, liquid, or other fluids passing through and / or contacting the electrical system of the steam evaporator device 100 can cause various undesirable effects, such as changes in pressure readings, and / or can cause the accumulation of materials (such as moisture or residue, misaligned portions of the evaporable material 102, etc.) in parts of the steam evaporator device 100. In these parts of the steam evaporator device, these materials can cause poor pressure signals, degradation of one or more sensors 113 or other components, and / or a shorter lifespan of the steam evaporator device 100. Leaks in the seals can also cause the user to inhale air that has passed through parts of the steam evaporator device 100 (such as the controller 104, power supply 112, and / or the like) containing materials that are not intended to be inhaled or that are made of such materials.

[0358] When one or more sensors 113 include a conductive surface for measuring the resistance of the heating element 142, the one or more sensors 113 may additionally or alternatively be positioned on a surface biased against a portion of the heating element 142. For example, one or more sensors 113 may be disposed on, or otherwise biased by, a spring or other resiliently deformable structure such that the one or more sensors 113 remain in physical contact with the surface of the heating element 142. Such an arrangement of springs or other resiliently deformable structures in the steam turbine assembly 100 can help mitigate the potential damaging effects on steam turbine components caused by interactions with environmental factors, such as those described herein.

[0359] In this embodiment, power supply 112 is part of steam generator body 110 and heating element 142 is housed in a steam generator apparatus within a housing 120 configured to couple with steam generator body 110. Housing 120 and steam generator apparatus 100 may include electrical connection features (e.g., electrical contacts, conductors, etc.) for performing physical circuitry including controller 104 (e.g., printed circuit board, microcontroller, or the like), power supply 112, and heating element 142. The circuitry performed by these electrical connections allows current to be delivered to heating element 142 (e.g., resistance heating element) and may be further used for additional functions, such as measuring the resistance of heating element 142 for determining and / or controlling the temperature of resistance heating element based on its resistivity thermal coefficient. In some implementations, different circuitry for measuring the resistance of heating element 142 may be provided compared to the circuitry that allows current to be delivered to heating element 142 (e.g., circuitry including one or more sensors 113 and heating element 142, as described herein).

[0360] Alternatively, the power supply 112 may be part of the steam generator body 110, and the heating element 142 may be housed in the housing 120 and configured as a heating stage to be electromagnetically coupled to one or more inductor coils that are part of the drive circuitry system 143 in the steam generator body 110. The physical circuitry in the steam generator body 110 includes a controller 104 (e.g., a printed circuit board, microcontroller, or the like), the power supply 112, and one or more inductor coils, which may be part of or form part of the drive circuitry system 143. The physical circuitry delivers current to one or more inductor coils and may be further used for additional functions, such as measuring the inductance, resistance, and / or impedance of the heating element 142 for determining and / or controlling the temperature of the heating element 142 based on its resistivity thermal coefficient. In some implementations, different circuitry for measuring the inductance, resistance, and / or impedance of the heating element 142 may be provided compared to circuitry that allows current to be delivered to one or more inductor coils (such as circuitry including one or more sensors 113, as described herein).

[0361] In some implementations, the container 118 may include all or part of a heating element 142 (e.g., a heating coil, resistance heating element, etc.) configured to heat the housing 120 received in the container 118 by conduction, radiation, convection, or other means. For example, the container 118 may include various implementations of the heating element 142 configured to receive the housing 120 and / or positioned in contact with the housing 120. Various implementations of the heating element 142, container 118, and housing 120 for integration within and / or use with various steam generator bodies 110 to form an inhalable aerosol are described herein.

[0362] In some implementations, the housing 120 may be configured to insert into the receiver 118, such as for forming contact between the outer surface of the housing 120 and one or more inner walls of the receiver 118. In some implementations, the housing 120 may have the same or similar shape as the receiver 118. In some implementations, the housing 120 may comprise a square or rectangular shape. In some implementations, the housing 120 may comprise a circular cross-section and / or a cylindrical shape. In some implementations, the housing 120 may have a non-circular cross-section transverse to a longitudinal axis, along which it is inserted into the receiver 118. The non-circular cross-section of the housing 120 and / or the receiver 118 may comprise two sets of parallel or nearly parallel opposing sides (e.g., having a parallelogram-like shape), or other shapes having at least second-order rotational symmetry, including curved shapes. For example, Figures 8A to 8F An example cross-section of the housing 120 and / or the container 118 is shown, including a rectangular shape. Figure 8A ), and the modified rounded rectangular shape ( Figure 8B ), oval or egg-shaped Figure 8C or other shapes that include corners, bends, edges, protrusions, recesses and / or similar features. Figures 8D to 8F In this context, the approximate shape indicates a basic similarity to the shape being described, but the edges of the shape in question need not be perfectly straight and the vertices need not be perfectly sharp. In the description of any non-circular cross-section mentioned herein, rounding of either or both of the edges or vertices of the cross-sectional shape is considered.

[0363] In some implementations, at least one of the inner walls forming the reservoir 118 may include a heating element 142 and / or a thermally conductive material. For example, a configuration in which the casing 120 forms a sliding fit and / or close contact with the reservoir 118 allows for efficient heat transfer between the heating element 142, the reservoir 118, and the casing 120, thereby resulting in efficient and effective heating of the evaporable material 102 within the casing 120. In other implementations, at least one of the inner walls forming the reservoir 118 may include a ridge that contacts the casing 120 only at specific locations to minimize conductive heat loss from the casing due to physical contact with the unheated surfaces of the steam generator body 110. For example, the housing 120 in which the heater portion 141 (or other heat-conducting portion) of the housing 120 contacts the housing 118 only in certain areas (such as areas away from the heating element 142) can be configured to allow a higher temperature to be maintained at the heating element 142, thereby resulting in efficient and effective heating of the evaporable material 102 within the housing 120.

[0364] Furthermore, the housing 120 may comprise a compressed and / or high-density configuration of the non-liquid evaporable material 102, which can further facilitate efficient and effective heating and convert one or more compounds present in the evaporable material 102 into a gaseous phase. For example, the evaporable material 102 in a compressed and / or high-density configuration may contain a minimal amount of air or cavitation, thereby increasing the efficiency and effectiveness of heat transfer within the evaporable material 102. This configuration allows for reduced power consumption, at least because less heating power is required to effectively heat the evaporable material 102 to a temperature sufficient to cause the release of inhalable substances. Additionally, lower temperatures (e.g., at the contact surfaces of the oven or heating elements) can be used to heat the evaporable material 102, at least due to the improved heating efficiency of the evaporable material 102, which can also reduce power consumption and the formation of harmful byproducts resulting from heating the evaporable material at higher temperatures. Various implementations of the housing 120 described herein, comprising evaporable materials formed in a compressed and / or high-density configuration, are used to achieve at least some of the benefits described above.

[0365] In some implementations, the vaporizer device 100 may include a heating system configured to receive and heat the evaporable material 102 to generate an inhalable aerosol. For example, the heating system may include one or more heating elements 142 positioned at, against, near, within, outside, and / or along the walls of the container 118 (e.g., extending along at least a portion of the wall at the distal end (e.g., the bottom) of the container 118, extending along at least a portion of each of the distal wall and / or sidewalls of the container 118, etc.). In some implementations, the one or more heating elements 142 may be configured to heat one or more of the walls of the container 118 from the outside to the inside of the container 118 (e.g., where the evaporable material 102 is inside the container 118). In another example, the heating system may be implemented by including one or more heating elements 142 positioned at, against, near, within, outside, and / or along the walls of the housing 120 (e.g., extending along at least a portion of the wall at the distal end (e.g., the bottom) of the housing 120, extending along at least a portion of the distal wall and / or sidewalls of the housing 120, etc.). In some implementations, one or more heating elements 142 may form one or more of the walls of the housing 120 to heat from the outside of the housing 120 to the inside (e.g., where the evaporable material 102 is inside the housing 120 and optionally inside the heating elements 142).

[0366] The heating system may also include at least one airflow path, which may be configured to move heated air through the evaporable material 102. As will be described in more detail below, the heating system may be configured to receive the housing 120 and heat the housing 120 using at least one heating element 142 to provide an inhalable aerosol for a user to inhale via one or more airflow paths.

[0367] This document describes various implementations of such a heating system for the vaporizer device 100, which offer several benefits, including uniform heat distribution through the evaporable material 102 of the casing 120. This can result in improved inhalable aerosol generation, less energy required to form inhalable aerosols and / or lower average temperatures, as well as increased user satisfaction with device use and consumption of the evaporable material 102.

[0368] In some implementations, the heating system of the vaporizer device 100 is configured to heat a non-liquid evaporable material, such as a tobacco-based material. For example, the vaporizer body 110 may include one or more heater portions 141 or containers 123, each of which receives and heats the evaporable material 102 via one or more heating elements 142, thereby generating an inhalable aerosol. In some implementations, the vaporizer device 100 may include one or more airflow paths extending through a cartridge 120 positioned within a respective reservoir 118 and leading to a user through a mouthpiece portion 130.

[0369] In some implementations, the housing 120 may include one or more barriers configured to accommodate the evaporable material 102 and / or hold components of the housing 120 together. The one or more barriers may be provided by the heating element 142 itself, the container 123, the insert 124, an outer layer (such as one or more covering materials 122), and / or the like. The one or more barriers may be made of a vapor-impermeable and / or moisture-resistant material (e.g., at least to some extent resistant to the destructive effects of water). Such materials may include one or more of the following: metals, metal alloys, paper materials (such as cardboard), corrugated materials (such as cardboard or paper), tobacco paper, heat-resistant plastics (such as polyethylene terephthalate (PET)), cellulose acetate, non-wood plant fibers (such as flax, sisal, straw, and / or Spanish grass), and / or the like.

[0370] In some implementations, the use of metals such as aluminum in the heating element 142 and / or container 123 may be advantageous in cases where efficient heat transfer is required (e.g., where less energy is needed to diffuse across a large area) (which may be in the case of providing a single heat source). In other implementations, metals such as stainless steel in the heating element 142 and / or container 123 may be advantageous in cases where efficient heat transfer is less of a concern (e.g., where multiple heat sources are arranged to heat different areas of the housing 120). Enclosing the evaporable material 102 within a vapor-impermeable and / or moisture-resistant barrier protects the housing 118 and / or other parts of the steam evaporator device 100 from vapor deposits and / or residues of the evaporable material 102, thus eliminating the need to clean the heating element 142, housing 118, and / or other parts of the steam evaporator device 100 after use. In other words, one or more of the heating element 142, container 123, insert 124 and / or outer layer (e.g., one or more covering materials 122) may provide a barrier between the evaporable material 102 and the components of the steam generator body 110, wherein the barrier is optionally impermeable to steam and / or moisture resistant.

[0371] Figure 1A heater 141 and / or Figure 1B The container 123 of the housing 120 may be configured to hold the evaporable material 102 with a lid, an outer and / or inner layer (e.g., covering material 122), an insert 124, and / or other components configured to hold the evaporable material 102 therein. Various implementations of the heating system and the housing 120 are described in more detail below.

Figure 2 Any functional structure described in the steam generator device 200 can be found in Figures 1A to 1B It is implemented in or by the steam generator device 100.

[0373] For example, as illustrated, a steam generator assembly 200 may include a steam generator body 210, a container 218, and a flange 221 on the exterior of the container 218. As described herein, it contains an evaporable material 102 (containing... Figures 1A to 1CA housing 220 (in any implementation of the steam generator material 102) may be inserted into a container 218, and at least a portion of the housing 220 may remain outside the container 218, such as at least a portion of the suction portion 230 containing the airflow outlet 228. At least a portion of the heater portion 241 of the housing 220 may be inserted into and / or at least partially enclosed within the container 218. Although the suction portion 230 and the heater portion 241 may have substantially the same length dimensions along the length of the housing 220 (e.g., 1:1), other relative dimensions (e.g., about 1:2, 2:3, 3:4, 4:5, 5:4 and / or similar) are also contemplated.

[0374] As illustrated, the housing 220 may extend from a proximal end 220a to a distal end 220b and contains two or more portions, such as a heater portion 241 and a nozzle portion 230. The total distance between the proximal end 220a and the distal end 220b can be considered as the length of the housing 220, for example along... Figure 2 The drawing shows (and also as) Figure 3 (as shown in the diagram) the y-axis extension. Furthermore, any component of the housing 220 can be described as having, for example, the y-axis extension of the housing 220. Figure 2 In China (and also as) Figure 3 The length of the y-axis reference (shown in the diagram).

[0375] As illustrated, the steam generator body 210 may extend from the proximal end 210a to the distal end 210b. The total distance between the proximal end 210a and the distal end 210b can be considered as the length of the steam generator body 210, for example, along... Figure 2 The drawing shows (and also as) Figure 5A (as shown in the diagram) the y-axis extension. Furthermore, any component of the steam generator body 210 and the steam generator assembly 200 may be described as having, as illustrated by... Figure 2 In China (and also as) Figure 5A The length of the y-axis reference (as shown in the drawing of the components of the steam generator body 210).

[0376] The housing 220 can be considered to have two additional dimensions transverse to its length: depth and width. As mentioned herein, the depth of the housing 220 can be the distance between two points on opposite outer surfaces of the housing 220 (e.g., surface areas that are substantially the same size and shape when rotated about a central longitudinal axis) in a dimension perpendicular to the length of the housing 220, such as along a... Figure 2 The drawing shows (and also as) Figure 3 (as shown in the diagram) the z-axis extension. Furthermore, any component of the housing 220 can be described as having, for example, the z-axis extension of the housing 220. Figure 2 In China (and also as) Figure 3The depth of the housing 220 is a z-axis reference (illustrated in the diagram). In some implementations, the depth of the housing 220 can be understood as the maximum distance of the housing 220 along the z-axis and / or the distance between two opposing points on the exterior of the housing 220 (e.g., where the opposing points are opposite each other along an axis perpendicular to the center of the width of the housing 220). As mentioned herein, the width of the housing 220 can be the distance between two points on opposing surfaces of the exterior of the housing 220 in a dimension perpendicular to both the length and depth of the housing 220, and is the longer of the two lateral dimensions, for example, along an axis perpendicular to the center of the width of the housing 220. Figure 2 The drawing shows (and also as) Figure 3 (as shown in the diagram) x-axis extension. Furthermore, any component of the housing 220 can be described as having, for example, the x-axis extension of the housing 220. Figure 2 In China (and also as) Figure 3 The width of the housing 220 is referenced to the x-axis (illustrated in the diagram). In some implementations, the width of the housing 220 can be understood as the maximum distance of the housing 220 along the x-axis and / or the distance between two opposite points on the exterior of the housing 220 (e.g., where the opposite points are opposite each other along an axis perpendicular to the center of the depth of the housing 220). Therefore, the axis along which the width of the housing 220 extends may be referred to as the first transverse axis and / or the major axis of the housing, and the axis along which the depth of the housing 220 extends may be referred to as the second transverse axis and / or the minor axis of the housing.

[0377] The main surface of housing 220 extending along the width of housing 220 may be referred to as the long side of housing 220 and / or on the long side of housing 220, and the main surface of housing 220 extending along the depth of housing 220 may be referred to as the short side of housing 220 and / or on the short side of housing 220. Each of the reference surfaces of housing 220 may be a surface region on the exterior of housing 220. In some implementations, the longer opposing surface may be considered as offset along the depth of housing 220 on the long / longer side of housing 220, and the smaller opposing surface may be considered as offset along the width of housing 220 on the short / shorter side of housing 220. It will be understood that this terminology may be applied to any implementation of the housing and its sub-components (e.g., heater portion, nozzle portion, heating element, material layer, covering material, insert and / or the like) described herein, and for the sake of brevity, this terminology has not been redefined with respect to any implementation or sub-component.

[0378] The steam generator body 210 can also be viewed as having two additional dimensions transverse to its length: depth and width. As mentioned herein, the depth of the steam generator body 210 can be the distance between two points on opposite surfaces of the outer side of the steam generator body 210 in a dimension perpendicular to the length of the steam generator body 210, for example, along such a dimension. Figure 2 The drawing shows (and also as) Figure 5A(Drawn in the middle) the z-axis extension. Furthermore, any component of the steam generator body 210 and the steam generator assembly 200 may be described as having, as shown by... Figure 2 In China (and also as) Figure 5A The depth of the steam body 210 (as shown in the component diagram of the steam body 210) is referenced to the z-axis. In some implementations, the depth of the steam body 210 can be understood as the maximum distance of the steam body 210 along the z-axis and / or the distance between two opposite points on the exterior of the steam body 210 (e.g., where the opposite points are opposite each other along an axis perpendicular to the center of the width of the steam body 210). As mentioned herein, the width of the steam body 210 can be the distance between two points on opposite faces of the exterior of the steam body 210 in a dimension perpendicular to both the length and depth of the steam body 210, and is the longer of the two lateral dimensions, for example, along an axis perpendicular to the center of the width of the steam body 210. Figure 2 The drawing shows (and also as) Figure 5A (illustrated in the middle) x-axis extension. Furthermore, any component of the steam generator body 210 and the steam generator assembly 200 may be described as having, as shown in the diagram. Figure 2 In China (and also as) Figure 5A The width of the steam body 210 (as shown in the diagram of the components of the steam generator body 210) is referenced to the x-axis. In some implementations, the width of the steam generator body 210 can be understood as the maximum distance of the steam generator body 210 along the x-axis and / or the distance between two opposite points on the exterior of the steam generator body 210 (e.g., where the opposite points are opposite each other along an axis perpendicular to the center of the depth of the steam generator body 210). Therefore, the axis along which the width of the steam generator body 210 extends may be referred to as the first transverse axis and / or the long axis of the steam generator body, and the axis along which the depth of the steam generator body 210 extends may be referred to as the second transverse axis and / or the short axis of the steam generator body.

[0379] The surface of the vapor body 210 extending primarily along the width of the vapor body 210 may be referred to as the long side of the vapor body 210 and / or on the long side of the vapor body 210, and the surface of the vapor body 210 extending primarily along the depth of the vapor body 210 may be referred to as the short side of the vapor body 210 and / or on the short side of the vapor body 210. Each of the reference surfaces of the vapor body 210 may be a surface region on the exterior of the vapor body 210. In some aspects, the longer opposing surface may be considered as offset along the depth of the vapor body 210 on the long / longer side of the vapor body 210, and the smaller opposing surface may be considered as offset along the width of the vapor body 210 on the short / shorter side of the vapor body 210. It will be understood that this terminology may be applied to any implementation of the vapor body and its sub-components (e.g., retainer assembly, frame, inductor, flux concentrator, housing, and / or the like) described herein, and for the sake of brevity, this terminology has not been redefined with respect to any implementation or sub-component.

[0380] It will be understood that the elements described herein (e.g., steam generator apparatus, casing, steam generator body, and components thereof) may have surfaces defined in Euclidean or non-Euclidean space. Dimensions of ends, sides, faces, and / or the like existing in non-Euclidean space may be considered as dimensions of reference ends, sides, faces, and / or the like existing in Euclidean space. The distance between any two ends, sides, faces, points, etc., may be equal to the shortest distance between two opposite points at the center of each identified structure, component, area, part, etc. However, in cases where the structure, component, area, part, etc., is not of a uniform shape (e.g., the convex or concave ends of casing 220 and / or steam generator body 210), this distance may be equal to the longest distance along a plane or volume intersecting (or orthogonal to) the identified end, side, point, etc.

[0381] As used herein, the term "heater portion" may refer to the portion of the housing that contains a heating element or is otherwise heated during use (e.g., a section and / or subset of components). As used herein, the term "nipple portion" may refer to the portion of the housing that contains a nozzle or other components that a user places their mouth on during use (e.g., a section and / or subset of components). Although for simplicity, the housing is generally described herein with respect to the heater portion and the nozzle portion, it will be understood that additional portions may be provided within the housing, which may be at least partially upstream of, between, downstream of, adjacent to, inside and / or outside the heater portion and / or nozzle portion. For example, an external covering material or housing may be outside both the heater portion and the nozzle portion; a space or component may be disposed between the heater portion and the nozzle portion; the heater portion may include an insert and / or end cap upstream of or at least partially within the heater portion; the nozzle portion may include an insert and / or end cap downstream of or at least partially within the nozzle portion; and / or the like. Furthermore, it will be understood that, although sometimes described as separable, the nozzle portion 230 and the heater portion 241 can simply be regarded as general areas of the unit 220.

[0382] As illustrated, the steam generator device 200 may include one or more input devices 216a, 216b (collectively referred to as input devices 216), such as a pair of input devices 216a on opposite sides of the steam generator body 210 and / or one or more input devices 216b on the flange 221. In some implementations, one or more input devices 216a, 216b may include buttons (e.g., plastic, metal, elastomer), capacitive sensors, and / or the like. Similar to... Figures 1A to 1CThe controller 104 of the steam maker device 200 (not shown) can be configured to detect actuation (e.g., touch or force) of one or more input devices 216a, 216b based on signals or data provided by one or more input devices 216a, 216b. In an implementation where multiple input devices 216 are present, the controller 104 of the steam maker device 200 can be configured to activate the steam maker device 200 only in response to detecting actuation of all input devices 216 (e.g., two input devices 216a located on opposite sides of the steam maker body 210). It may be advantageous to provide multiple input devices 216 in different locations where they are unlikely to be accidentally activated (e.g., in locations where they are most likely to be touched simultaneously only during active use of the steam maker device 200). However, a simpler interface can be provided, such as by using input devices 216 in the form of a single button or multiple buttons.

[0383] In some implementations, the controller 104 of the steam generator 200 may be configured to select a predetermined operating temperature and / or heating profile from N temperatures or profiles. According to these implementations, the controller 104 of the steam generator 200 may be configured (and thus allow a user) to select a temperature or profile based on the detection of actuation of one or more input devices 216. In some implementations, the input devices 216 (e.g., input device 216a) may be used to increase and decrease the currently selected operating temperature (also referred to as the target temperature) and / or profile between zero (0) and N temperatures and / or profiles, where zero means the steam generator 200 is in a “closed” state (e.g., not actively heating the container 218, but otherwise configured to detect interaction with one or more components of the steam generator 200). Thus, input device 216 may be actuated to increase the currently selected operating temperature and / or profile, and the same or another input device 216 may be actuated to decrease the currently selected operating temperature and / or profile. Input device 216 can be actuated to provide switching between an "off" state and an "on" state (e.g., where the "on" state begins at a minimum preset temperature and / or profile) when one or more input devices 216 are actuated (e.g., pressed or held) for a predetermined time. As described herein, controller 104 can be configured to optionally heat different zones of heating element 143 at different temperatures and / or times.

[0384] In some implementations, the controller 104 of the steam generator device 200 may be configured to operate at one or more predetermined operating temperatures, such as powering the heating element 142 as described herein, based on a default or user-selected heating profile. For example, in some heating profiles, the controller of the steam generator device 200 may be configured to power the heating element 142 for a first time period at a first operating temperature, power the heating element 142 for a second time period at a second operating temperature, power the heating element 142 for a third time period at a third operating temperature, and / or the like. In some implementations, the controller 104 of the steam generator device 200 may be configured to power the heating element 142 based on the use of the steam generator device 200. For example, the operating temperature of the heating element 142 may be initially set to an initial operating temperature and / or the operating temperature may be dynamically changed depending on detected airflow, temperature, heating time, applied power, estimated evaporable material 102 used, remaining estimated evaporable material 102, and / or the like. Although the heating of the evaporable material 102 is sometimes described with respect to a single heating element 142, it will be understood that multiple heating elements 142 and / or multiple zones of a single heating element 142 can be implemented and / or controlled in the same or similar manner to provide greater control over the evaporation of the evaporable material 102.

[0385] In some implementations, the controller 104 of the steam generator 200 may be configured to detect when the heater portion 241 is present in the container 218 and / or for a sufficient duration. In response to determining that the heater portion 241 is present in the container 218 and / or for a sufficient duration, the controller of the steam generator 200 may switch the steam generator 200 between an "off" state and an "on" state, increasing the temperature to a range of zero (0) to N target temperatures, achieving a predetermined (e.g., user-selected) profile from a plurality of zeros (0) to N different profiles, and / or the like.

[0386] In some implementations, the controller 104 of the vaporizer device 200 may be configured to determine whether the housing 220 is depleted and / or should be replaced. This may occur when all, most, or an estimated threshold amount of one or more compounds present in the evaporable material 102 contained within the housing 220 has been converted to the gas phase, when the amount or quality of the evaporable material 102 present is insufficient to provide a user-satisfactory inhalable aerosol, and / or similar situations. For example, the controller 104 of the vaporizer device 200 may be configured to determine that the housing 220 is depleted and / or should be replaced based on the length of time the housing 220 has been heated, the temperature at which the housing 220 has been heated during that time period, or the temperatures at various points in multiple time periods (which may be measured via the controller 104 of the vaporizer device 200 as described herein) and / or similar. Based on the determination that the housing 220 is depleted and / or needs to be replaced, the controller 104 of the steam generator unit 200 may be designed to provide indications that the housing 220 is depleted and / or needs to be replaced, to switch the steam generator unit 200 to an "off" state, and / or the like. During operation, the controller 104 of the steam generator unit 200 may be configured to provide indications of an estimated amount of evaporable material 102 remaining in the housing 220 and / or an estimated amount of time remaining in the evaporation period during which the evaporable material 102 can be used (e.g., the period from when the steam generator unit 200 is heated or the container 218 reaches a predetermined operating temperature until when the housing 220 is depleted and / or needs to be replaced). In some implementations, the controller 104 may be housed in and / or in communication with the steam generator body 210 and / or the housing 220.

[0387] The steam generator device 200 may include a plurality of output terminals 217 (e.g., LEDs), which may be similar to output terminal 117. (e.g., vibration, sound, and / or the like), and the controller 104 of the vaporizer device 200 may be configured to illuminate one or more of the LED outputs 217 in response to detecting actuation of one or more of the input devices 216a, 216b, in response to detecting that the housing 220 has been inserted into the reservoir 218, to indicate the currently selected operating temperature and / or temperature profile; indicate the current temperature of the reservoir 218; indicate a comparison of the current temperature of the reservoir 218 with the currently selected operating temperature and / or temperature profile; indicate that the current temperature of the reservoir 218 has reached the currently selected operating temperature; indicate an estimated amount of remaining usable vaporizable material in the housing 220 (e.g., by selectively illuminating more or fewer LED outputs 217); indicate an estimated amount of time remaining in the evaporation period (e.g., by selectively illuminating more or fewer LED outputs 217); indicate that the housing 220 is used up and / or should be replaced; indicate the remaining battery power (e.g., the remaining voltage in the power supply 112), and / or the like. In some implementations, one or more input devices 216a, 216b may include one or more of the described LEDs (other than or in place of LED output 217), at least partially surrounded by the LEDs, and / or positioned relative to the LEDs such that the periphery of the light (e.g., a halo) at least partially surrounds the periphery of one or more input devices 216a, 216b.

[0388] The controller 104 of the steam generator device 200 may be configured to illuminate LEDs in one or more colors and / or according to one or more patterns (e.g., multiple LED outputs 217 and / or LEDs near input devices 216a, 216b). For example, the controller 104 of the steam generator device 200 may be configured to illuminate LEDs in different colors to indicate the current temperature of the container 218 (e.g., oven), flash once or multiple times to indicate that the current temperature of the container 218 has reached the currently selected operating temperature, and / or similarly. Alternatively, controller 104 may be configured to provide tactile feedback (e.g., via one or more outputs 217, such as a motor, linear resonant actuator, and / or the like) to indicate that one or more input devices 216a, 216b have been pressed, whether the steam generator device 200 has switched between an "off" and / or "on" state (e.g., the container 218 is heating), the current temperature of the container 218 (e.g., in a periodic pattern with increasing frequency), whether the current temperature of the container 218 has reached the currently selected operating temperature, when a threshold amount of an estimated amount of available evaporable material remaining in the housing 220 has been reached, when a threshold amount of an estimated amount of time remaining in the evaporation period has been reached, that the housing 220 has been used up and / or should be replaced, and / or the like. Although depicted as a generally flattened cylindrical shape, the cross-section of the housing 220 and / or the steam generator body 210 may be of different shapes. For example, in some implementations, the cross-section of the housing 220 and / or the steam generator body 210 may be similar to Figures 8A to 8F One or more of the cross sections. The cross section may be located at any position between the respective distal and proximal ends of each of the casing 220 and / or steam generator body 210.

[0389] Figure 3 This is a perspective view illustrating the implementation of the housing 320 in an exploded schematic form, consistent with the implementation of the current topic. The housing 320 can be... Figures 1A to 1B The box body 120 and / or Figure 2 The implementation of one or more components of the casing 220, and / or configuration for use in steam generator devices (such as...) Figures 1A to 1B Steam generator devices 100a, 100b and / or Figure 2 Within a steam generator assembly 200. As illustrated, a housing 320 may extend from a proximal end 320a to a distal end 320b and contains two or more portions, such as a heater portion 341 and a suction nozzle portion 330. As described herein, the total distance between the proximal end 320a and the distal end 320b of the housing may be considered as the length of the housing 320, and transverse to the length of the housing 320 are the width (longer dimension, x-axis) and the depth (shorter dimension, z-axis). As further described herein, the housing 320 may have surfaces defined in Euclidean or non-Euclidean space.

[0390] As illustrated, heater portion 341 may include heating element 342 and evaporable material 302. Heating element 342 and / or evaporable material 302 may extend between a proximal end 341a and a distal end 341b of heater portion, and the total distance (dimension) between these two ends may be referred to as the length of heater portion 341. For convenience, the length of heater portion 341 may be referenced relative to a longitudinal axis (y-axis), along which housing 320 is inserted into a receiver (e.g., along the longitudinal axis). Figure 2 In the housing 218). The heater portion 341 can also be considered to have two additional dimensions transverse to the length of the heater portion 341, the two additional dimensions being the width (longer dimension, x-axis) and the depth (shorter dimension, z-axis).

[0391] In implementations where the width of the heater portion 341 is greater than its depth and / or the width of the evaporable material 302 is greater than its depth (e.g., in a 3:2 ratio, 9:5 ratio, 2:1 ratio, 9:4 ratio, 5:2 ratio, or greater), heat transfer can be more efficient. For example, relative to a cylindrical surface, a heating element 342 and / or evaporable material 302 comprising two wider opposing surface regions (e.g., faces) with a shorter distance between two opposing surfaces allows the vaporizer device to be actively heated only from one or both of the opposing sides, rather than on the entire surface of the cylindrical surface. The unheated remaining portion of the heating element 342 can be configured to absorb and redistribute heat from the actively heated adjacent area, thereby providing heat to a surface area of ​​the evaporable material 302 that is much larger than the cylindrical surface. While this non-cylindrical structure (e.g., elliptical or oval) is more difficult to manufacture than a cylindrical structure, it benefits the user by making the system easier and more comfortable to use (e.g., a more ergonomic structure that conforms to the natural shape of the user's lips). Additionally, the increased efficiency and use of less power allow for longer battery life and / or less space constraints on the vaporizer device (e.g., the use of smaller batteries). Finally, the heating method of the heating element 342 and / or the evaporable material 302 can affect the temperature at which the evaporable material 302 is heated and / or the rate at which one or more compounds present in the evaporable material 302 are converted to the gas phase and / or otherwise released from the evaporable material 302.

[0392] As discussed herein, heating element 342 can be configured to convert electrical energy into heat (e.g., through induction heating, resistance heating, etc.). However, in some implementations, Figure 3 The heating element 342 can instead be considered as a container that receives heat from an external heat source and distributes it to the evaporable material 302 (e.g., similar to...). Figure 1B(Container 123). In implementations where induction heating is used to heat heating element 342, providing a wider surface area has other advantages. For example, eddy currents are more easily generated in a wider and flatter surface compared to a smaller or curved surface. Additionally, the larger surface area of ​​heating element 342 allows for direct thermal contact between the larger surface area of ​​heating element 342 and a larger area of ​​evaporable material 302. These eddy currents can be generated on the larger surface area with less energy, and / or the larger surface area can provide multiple smaller areas that can be selectively marked using multiple smaller inductors. In this regard, it is advantageous to use a heating stage that inductively heats at least primarily by forming eddy currents rather than by hysteresis (as in the case of a heating stage including magnetic and / or ferrite materials). In implementations where eddy currents are the primary (e.g., all) form of heat generation, the induction coil may comprise Litz wire or otherwise be formed from Litz wire. As used herein, Litz conductors may refer to conductors formed of multiple strands of metal (e.g., 5, 10, 20, 40, etc.) twisted or braided together, and may optionally include an outer insulation material, a material core, and / or the like.

[0393] In some implementations, a non-ferrite and / or non-magnetic heating stage is provided. For example, aluminum can be considered non-ferrite and non-magnetic, and thus substantially unaffected by hysteresis. Where there is no effect or substantially no effect on the temperature generated via hysteresis, the temperature of the non-ferrite and / or non-magnetic heating stage can be derived based on the direct relationship between the temperature of the heating stage and eddy currents, as described herein. Although inductors and / or induction coils may be referred to herein as “heating” the heating stage and / or heating element, those skilled in the art will understand that heating in this sense can be considered as the inductor generating magnetic and / or electromagnetic energy that is radiated to and absorbed by one or more segments of the heating stage, and then converted into heat via eddy currents and / or hysteresis.

[0394] At least a portion of the heater section 341 may be accommodated in the covering material 322. The covering material 322 may be similar to... Figures 1A to 1BThe outer layer (e.g., covering material 122). For example, the covering material 322 may be made of one or more of the following materials: paper materials (such as cardboard), corrugated materials (such as cardboard or paper), tobacco paper, heat-resistant plastics (e.g., PET), non-wood plant fibers (such as flax, sisal, straw, and / or Spanish grass), and / or similar materials. The covering material 322 may extend along all or at least a portion of the length of the heater portion 341 and define an internal volume between the depth and width of the heater portion 341. The evaporable material 302 may fill most of the volume, but other components may be present, such as end caps and / or dividers configured to at least partially enclose the ends of the volume. In some implementations, the heating element 342 extends along all or at least a portion of the length of the heater portion 341 and defines an internal volume between the depth and width of the heater portion 341, within which the evaporable material 302 may be accommodated.

[0395] In some implementations, the evaporable material 302 may be formed from tobacco leaves (e.g., dried, cut, shredded, and / or reconstituted), tobacco stems (dried, cut, shredded, and / or ground), a carrier, and / or an acid (e.g., an organic acid, such as benzoic acid, citric acid, and / or the like). The ratio of tobacco leaves to tobacco stems may be based on the total amount of nicotine to be delivered and may vary depending on the type of tobacco used. Tobacco stems may provide a smoking-like sensation upon evaporation, but with a lower nicotine content. The carrier may be formed from vegetable glycerin, propylene glycol, and / or the like. In some implementations, the carrier may form 30% to 50% of the total weight of the evaporable material 302. Since tobacco naturally contains some moisture, the weight percentage of the carrier may be measured relative to the dry weight of the evaporable material (e.g., substantially water-free).

[0396] Including a carrier (such as vegetable glycerin) as at least 30% of the dry weight of the evaporable material 302 can produce a smoother inhalable aerosol and provide users with a more pleasant and unique experience than smoking combustible cigarettes and other available heated but non-combustible products. For example, a housing 320 containing the evaporable material 302 having a carrier comprising at least 30% of the dry weight of the evaporable material 302 can allow for lower evaporation temperatures (e.g., up to about 100 degrees Celsius), and thus allow for less odor, higher flavor extraction efficiency, a net reduction in HPHC (harmful and potentially harmful components) such as less charring, a more adjustable experience, more uniform evaporation of nicotine from tobacco over time, faster heating times (e.g., 10 to 15 seconds or longer compared to 20 to 30 seconds), and / or the like. In example implementations of the evaporable material 302, tobacco leaves and stems are in a ratio of approximately 1:1, 1:2, 2:3, 3:4, or 4:5, and vegetable glycerin constitutes at least 30% of the dry weight of the evaporable material 302, such as approximately 30%, 35%, 40%, 45%, or less than 50%. For example, in some implementations, the evaporable material 302 comprises tobacco leaves and stems in an approximately 1:1 ratio and approximately 35% by weight (dry) of vegetable glycerin. A higher amount of carrier can lead to degradation of components of the vaporizer bodies 110, 120 (such as containers 118, 218) if not properly compensated for.

[0397] In some implementations, a carrier (e.g., vegetable glycerin) may be added at multiple stages of the assembly of the cartridge 320. For example, as part of a first series of steps, tobacco material (e.g., tobacco leaves and / or stems) may be dried and mixed with a carrier to form a mixture, wherein the carrier constitutes at least 20%, at least 25%, at least 30%, or at least 35% of the dry weight of the evaporable material 302. Prior to mixing the tobacco material with the carrier, the tobacco material may be cut, shredded, and / or similarly processed. For example, the tobacco material may be shaped to be cut into smaller pieces, thereby improving its ability to absorb the carrier. As part of a second series of steps, the resulting mixture may be shaped to be more easily incorporated into the cartridge 320 (e.g., a block), and additional carrier material may be applied to the shape and / or portion of the cartridge 320. For example, in some implementations, the interior portions of the cartridge 320 (e.g., the interior of the heating element 342) may be sprayed with additional carrier material. Alternatively or concurrently, before and / or after the evaporable material is placed within the internal volume of the heating element 342, additional carrier material may be applied to the shaped form of the evaporable material 302, such as by spraying and / or injection. Once the cartridge 320 is fully assembled, the carrier may constitute at least 30%, at least 35%, at least 40%, at least 45%, or at least 50% of the dry weight of the evaporable material 302. Assembly in this manner allows for the use of less complex machinery to mix the tobacco material with the carrier, while also providing a cartridge 320 with a higher concentration of carrier in the evaporable material 302. In some implementations, applying additional carrier to the exterior of the shaped form of the evaporable material 302 and / or the interior of the heating element 342, relative to the evaporable material 302 formed by a simple mixture of tobacco material and carrier, may contribute to providing a more uniform vapor and aerosol over time, as the heat generated by the heating element 342 is more likely to evaporate the carrier first.

[0398] To control the composition of inhalable aerosols, it can be beneficial to separate the tobacco material from the carrier of the evaporable material. For example, Figures 17A to 17H A block diagram illustrating various implementations of tobacco material 1798 and carrier 1799 that can be combined to form different forms of evaporable materials 1702a to 1702h. (See diagram for example.) Figure 17A As illustrated, tobacco material 1798 and carrier 1799 may occupy approximately the same volume within evaporable material 1702a and are positioned relative to each other with respect to a cross-section defined by the length and width of evaporable material 1702a. Figure 17B As illustrated, tobacco material 1798 may occupy a volume within the evaporable material 1702b that is smaller than the volume occupied by carriers 1799a and 1799b (e.g., at a 1:2 ratio, a 1:3 ratio, and / or similar), and tobacco material 1798 may be positioned upstream of and off-axis from a cross-section defined by the length and width of the evaporable material 1702a. Figure 17C As illustrated, tobacco material 1798 and carrier 1799 may occupy approximately the same volume within evaporable material 1702c, and are positioned relative to each other with respect to a cross-section defined by the length and depth of evaporable material 1702c. Figure 17D As illustrated, tobacco material 1798 may occupy a volume within the evaporable material 1702d that is larger than the volume occupied by carrier 1799 (e.g., at a ratio of 2:1, 3:1, and / or similar), and the volume occupied by carrier 1799 may surround the volume occupied by tobacco material 1798. Figure 17E As illustrated, tobacco material 1798 and carrier 1799 may occupy approximately the same volume within the evaporable material 1702e, and are positioned on top of each other relative to a cross-section defined by the depth and width of the evaporable material 1702e. Figure 17F As illustrated, tobacco material 1798 and carrier 1799 may occupy different volumes within evaporable material 1702f, and are positioned on top of each other relative to a cross-section defined by the depth and width of evaporable material 1702f, with an air gap between tobacco material 1798 and carrier 1799. Figure 17G and Figure 17H As shown in the illustration, tobacco material 1798 and carrier 1799 may occupy different volumes within evaporable materials 1702g and 1702h, and are positioned relative to each other with respect to the cross-section defined by the length and width of evaporable materials 1702g and 1702h.

[0399] exist Figures 17A to 17H In various implementations, the evaporated materials from the heated tobacco material 1798 and the heated carrier 1799 can be combined to form a combined evaporated material, such as at or near the intersection of the volumes occupied by the tobacco material 1798 and the carrier 1799. The volume forming the combined evaporated material may be in fluid communication with a vapor inlet 1735, which may be similar to vapor inlets 335, 435, 635 described herein. In some implementations, separate heating elements 342 and / or inductors may be included to heat the respective volumes of the tobacco material 1798 and the carrier 1799. Therefore, different amounts of heat can be applied separately to the tobacco material 1798 (e.g., at a higher temperature) and the carrier 1799 (e.g., at a lower temperature) to optimize the user experience. Figures 17A to 17H In any of the implementation methods, a wicking material including carrier 1799 may be included to hold carrier 1799 within the desired volume.

[0400] In some implementations, the heating element 342 may be formed of a metal, such as aluminum, aluminum alloys, copper, brass, zirconium, stainless steel (ferrite or non-ferrite), nickel, and / or the like. As described herein, aluminum is advantageous for diffuse heat, and stainless steel is better suited for localized heating. For induction heating methods, the use of non-magnetic materials (such as aluminum) allows for the generation of eddy currents in the heater of the heating stage, while magnetic materials (such as ferrite stainless steel) are induction heated via a hysteresis mechanism. These two heating methods typically require different inductor coil arrangements, which may have different requirements, such as the amount of power required to generate the electromagnetic field. However, in some implementations, the heating element 342 is non-ferrite and non-magnetic, which simplifies the design of the steam generator apparatus 100, 200 and allows for more stringent control over the heating of the heating element 342.

[0401] The heating element 342 may be formed of one or more parts and may define all or substantially all of the walls (e.g., the bottom wall and periphery along the longitudinal axis, wherein either or both may have perforations or other openings) defining the volume in which the evaporable material 302 may be inserted. However, for ease of manufacture, the heating element 342 may be a single sheet of metal configured to be (at least partially) wound around the periphery of the heater portion 341. The two ends of the heating element 342 sheet may be abutted or close to each other at or near the joint location 345, as... Figure 3 The heating element 342 is shown in the diagram and optionally forms a continuous loop. In some implementations, when assembled within the housing 320, the surface of the heating element 342 that faces and / or touches the evaporable material 302 can be considered the inner surface of the heating element 342, and the surface of the heating element 342 that faces away from and / or does not touch the evaporable material 302 can be considered the outer surface of the heating element 342. When the heating element 342 is formed of backing paper metal, the exposed surface of the metal material can be considered the inner surface of the heating element 342, and the exposed surface of the paper material can be considered the outer surface of the heating element 342. In implementations where the assembled heating element 342 includes overlapping and / or intersecting portions, the inner and outer surfaces of the heating element 342 can be defined relative to the heating element 342 prior to assembly. In some implementations, the joint location 345 can be considered a location or area at or near one end of the heating element 342, such as where that end of the heating element 342 is at or near the other end or another area of ​​the heating element 342. When heating elements 342 partially overlap, joint location 345 may optionally be considered as the overlapping portion partially demarcated by the ends of heating elements 342. Alternatively, in some implementations, joint location 345 may be considered as a location or area at or near the point where a joint is formed between two portions of heating element 342 (e.g., via direct physical contact, welding, gluing, and / or the like).

[0402] Optional variations of heating element 342 and connector position 345 are available in Figures 15A to 15K The diagram shows heating elements 1542a to 1542k (collectively referred to as heating elements 1542) and a connector location 1545. In some implementations, a portion of the heating elements 1542, 1542 near one end (e.g., relative to a sheet of material forming the heating elements 1542, 1542) at least partially overlaps with a portion near the other end of the heating elements 1542 (such as near connector locations 345, 1545). The overlapping portions may be welded, glued, crimped, interlocked, pressed, or otherwise connected together. For example, as... Figure 15E and Figure 15I As illustrated, the overlapping portions of heating elements 1542e and 1542i can be connected together, wherein the outer surface of one end of heating elements 1542e and 1542i near the other end of heating elements 1542e and 1542i contacts the inner surface of heating elements 1542e and 1542i near the other end. In another example, such as Figure 15F As shown in the figure, the overlapping portions of the heating elements 1542f can be pressed or knurled together, wherein the outer surface of the heating element 1542f near one end of the heating element 1542f is connected to the inner surface of the heating element 1542f near the other end.

[0403] In other implementations, a portion of the heating element 342, 1542 near one end of the heating element 342, 1542 (e.g., relative to the sheet of material forming the heating element) intersects with another portion of the heating element 1542 near the joint location 345, 1545, and the intersecting portions are connected together by welding, gluing, crimping, interlocking, pressing, or other means. For example, as Figure 15G As illustrated, the intersecting portions of the heating elements 1542g can be pressed together or knurled, with the internal regions of the heating elements 1542g facing each other. In another example, such as Figure 15H and Figure 15J As illustrated, the intersecting portions of heating elements 1542h and 1542j can be folded or edged together, with the internal regions of heating elements 1542h and 1542j facing each other. When heating element 1542h is disposed within housing 320, capacitor region 1549 can be folded so that it is adjacent to the outer surface of the portion of heating element 1542h that does not form capacitor region 1549. In some implementations, Figure 15JThe folding of the heating element 1542j can be viewed as forming a volume configured to hold the evaporable material 302, such as a bucket, basket, and / or the like. These folds may include multiple intersecting regions in which areas of the inner surfaces of the heating element 1542j contact each other, and multiple intersecting regions in which areas of the outer surfaces of the heating element 1542j contact each other. It will be understood that such an implementation allows current to travel through the intersecting regions, regardless of whether the outer surfaces of the heating element 1542j are formed of a non-conductive material.

[0404] The overlapping or intersecting portions of the heating elements 1542 can be large enough that they form a capacitor region 1549. This improves the performance of the heating elements 1542 by providing a path for current to flow across or through the capacitor region 1549. In some implementations, the capacitor region 1549 can be considered as the region between two adjacent junction locations 1545, such as... Figure 15F , Figure 15G , Figure 15I , Figure 15J The diagram is shown in the figure. According to these implementations, the capacitor region 1549 can be considered as including a first portion of the heating element 1542 near a first end of the heating element 1542 and an overlapping or intersecting second portion of the heating element 1542 near a second end of the heating element 1542 (e.g., opposite each other along a common axis). Alternatively, the capacitor region 1549 can be considered as (or at least includes) a region of the heating element 1542, wherein a path for current flow is formed between adjacent overlapping, intersecting, or otherwise connected portions of the heating element 1542.

[0405] In some implementations, overlapping portions of the heating element 1542 in the junction location 1545 and / or capacitor region 1549 may be joined (e.g., welded, glued, crimped, interlocked) together such that any intermediate non-metallic or non-conductive portion of the heating element 1542 is sufficiently disassembled or removed to provide a path for current to flow between the overlapping portions. For example, if the heating element 1542 is formed of backing paper metal, the intermediate paper portion between two overlapping metal portions of the heating element 1542 may be disassembled or removed to allow current to flow between the metal portions.

[0406] In some implementations, a conductive adhesive may be applied to overlapping or intersecting portions (e.g., within junction location 1545 or capacitor region 1549), which may further improve the path of current flow. For example, the conductive adhesive may comprise an adhesive or paste containing silver, gold, copper, graphite, aluminum, and / or other conductive materials.

[0407] In some implementations, the ends of the heating element 1542 near the junction location 345 (e.g., both pointing inwards or both pointing outwards away from the evaporable material 302, such as at approximately right angles) are bent, and the intersecting portions are welded, glued, crimped, interlocked, or otherwise connected together. For example, Figure 15G The heating element 1542g includes a capacitor region 1549 formed by interlocking opposite ends of the heating element 1542g between two illustrated connector locations 1545. When the heating element 1542g is disposed within the housing 320, the capacitor region 1549 is foldable such that it is adjacent to the outer surface of the portion of the heating element 1542g that does not form the capacitor region 1549. In other implementations, the ends of the sheet may be formed in complementary shapes, which are designed to mechanically interlock with opposing tabs (e.g., relative to the sheet of material forming the heating element) formed at opposite ends of the heating elements 342, 1542, which are configured to be secured to each other when the opposite ends of the heating elements 342, 1542 are combined.

[0408] In other implementations, the heating element 1542 is made of a sufficiently rigid material so that its ends do not need to be physically coupled to each other, but can still be in contact with each other. In other implementations, the ends of the heating element 1542 are close to each other but do not physically touch (see, for example...). Figure 15B For example, heating element 1542 may be configured to be wound around 95% to 99%, greater than 90%, and / or less than 100% of the inner periphery of housing 320 and / or heater portion 341. In other implementations, the ends of heating element 1542 are close to each other, and one or more bridging portions between the ends of heating element 1542 (which may also form one or more capacitor regions 1549) are formed via welding (e.g., laser welding, ultrasonic knurling, electron beam welding, gas flame welding, friction welding, etc.) and / or the like. For example, as Figure 15C and Figure 15D As illustrated, the bridging portion can be formed as the illustrated capacitor region 1549. In other implementations, the heating element 1542 is formed as a single continuous material ring without connector positions 345, 1545 (see example...). Figure 15A ).

[0409] As described herein, specific portions of heating elements 342, 1542 (e.g., during manufacturing, during use, etc.) can be modified to provide specific electrical properties that allow for greater control over the current flowing through heating elements 342, 1542. For example, as Figure 15IAs shown herein, heating element 1542i may include a top region 1559a and a bottom region 1559b, wherein one or more regions 1559c are removed (e.g., cut away) between the top region 1559a and the bottom region 1559b. As described herein, current can be induced in the top region 1559a and / or the bottom region 1559b via inductance. For example, current can be induced in the top region 1559a via an electromagnetic field generated from one or more inductors adjacent to the top region 1559a, and current can be induced in the bottom region 1559b via an electromagnetic field generated from one or more inductors adjacent to the bottom region 1559b. In some implementations, it may be advantageous to heat the top region 1559a and the bottom region 1559b at different times, temperatures, frequencies, and / or the like. Therefore, it is advantageous to provide a heating element 1542h that is made of a minimum number of materials (e.g., a single metal sheet or a single backing metal sheet, with or without welding or gluing the opposite ends of the sheets together) and is easy to manufacture, while still providing at least two independently controllable zones.

[0410] In some implementations of the heating element 1542i, the presence of region 1559c (or the absence of material within region 1559c) may reduce or otherwise alter the flow of current and / or heat between or within the conductive regions of the heating element 1542i. For example, when a current is induced in the top region 1559a of the heating element 1542i, the presence of region 1559c (e.g., the absence of material) may retain most of the induced current and / or generated heat within the top region 1559a, and / or significantly reduce the amount of current and / or heat induced in the top region 1559a flowing or traveling to the bottom region 1559b. Similarly, when a current is induced in the bottom region 1559b of the heating element 1542i, the presence of region 1559c (e.g., the absence of material) can retain most of the induced current and / or generated heat within the bottom region 1559b, and / or significantly reduce the amount of current and / or heat induced in the bottom region 1559b flowing or traveling to the top region 1559a. In some implementations, retaining most of the induced current within specific regions 1559a, 1559b can be considered as less than 50% of the induced current traveling through another region (or the set of all other regions present) 1559b, 1559a, less than 40%, less than 30%, less than 20%, less than 10%, less than 5%, less than 2%, less than 1%, or the like. In some implementations, keeping most of the heat generated within specific zones 1559a, 1559b can be considered as less than 50% of the generated heat traveling to another zone (or the set of all other zones that exist) 1559b, 1559a, less than 40%, less than 30%, less than 20%, less than 10%, less than 5%, less than 2%, less than 1%, or similar.

[0411] As described herein, the relative sizes of regions 1559a and 1559b may differ. Although illustrated as comprising two regions 1559a and 1559b separated by a single cutout region (e.g., opening) 1559c on each of the long sides of heating element 1542, additional regions are possible. For example, heating elements 342 and 1542 may comprise three regions 1559 separated by two cutout regions 1559 on each of the long sides of heating elements 342 and 1542, four regions 1559 separated by three cutout regions 1559 on each of the long sides of heating elements 342 and 1542, and / or similar. As described herein, the relative sizes of each region 1559 (e.g., length along the y-axis, width along the x-axis, and / or depth along the z-axis) may correspond to one or more dimensions of an adjacent inductor. For example, the length of each zone 1559a may be substantially the same as the length of the adjacent inductor, the length of each zone 1559a may be between 100% and 110% of the length of the adjacent inductor, the length of each zone 1559a may be between 90% and 100% of the length of the adjacent inductor, and / or similar. Alternatively, the width of each zone 1559a may be substantially the same as the width of the adjacent inductor, the width of each zone 1559a may be between 100% and 110% of the width of the adjacent inductor, the width of each zone 1559a may be between 90% and 100% of the width of the adjacent inductor, and / or similar.

[0412] Further modifications (e.g., during manufacturing, during use, etc.) can be made to specific portions of the heating elements 342 and 1542 to provide specific electrical properties that allow for greater control over the current flowing through the heating elements 342 and 1542. For example, such as Figure 15J and Figure 15K As shown, heating elements 1542j and 1542k may include a top region 1559a and a bottom region 1559b, wherein one or more regions 1559c are removed (e.g., cut off). Figure 15K As illustrated, prior to the final assembly of the heating element 1542k, multiple regions 1559c can be removed from the heating element 1542k, such as from each of the four corners of the heating element 1542k (e.g., relative to a generally flat sheet of material forming the heating element 1542k). Subsequently, the opposite ends of the top region 1559a and the opposite ends of the bottom region 1559b of the heating element 1542k can be folded upwards. The opposite ends of the bottom region 1559b can be further folded, such that they form multiple intersecting regions, similar to those in… Figure 15J Multiple cross regions are illustrated between the connector positions 1545 in the assembled heating element 1542j. As described herein, these multiple cross regions may form a capacitor region 1549. In some implementations, a mandrel can be used from... Figure 15K The heating element 1542k is formed Figure 15JThe shape of the heating element 1542j.

[0413] As described herein, current can be induced in the top region 1559a and / or the bottom region 1559b via inductance. For example, current can be induced in the top region 1559a via an electromagnetic field generated from one or more inductors adjacent to the top region 1559a, and current can be induced in the bottom region 1559b via an electromagnetic field generated from one or more inductors adjacent to the bottom region 1559b. Similar to... Figure 15I The presence of the cut area 1559c (or the absence of material within the area 1559c) may reduce or otherwise alter the flow of current and / or heat between or within the conductive areas of the heating element 1542j.

[0414] Although the terms "top" and "bottom" are used with respect to zone 1559, in some implementations, top zone 1559a may be closer to the distal end of heating elements 342, 1542 and / or housing 320, and bottom zone 1559b may be closer to the proximal end of heating elements 342, 1542 and / or housing 320. For example... Figure 15K As illustrated herein, heating elements 342, 1542 may include an additional region 1559d that is removed (e.g., cut off) from heating elements 342, 1542. When the additional removed region 1559d is closer to the distal end of heating elements 342, 1542 and / or housing 320, region 1559d may provide an air inlet for air to enter heating elements 342, 1542 and / or housing 320, as described herein. When the additional removed region 1559d is closer to the proximal end of heating elements 342, 1542 and / or housing 320, region 1559d may provide a vapor outlet for vaporized material to exit heating elements 342, 1542, exit heater portion 341 and / or enter nozzle portion 330, as described herein. In either case, the additional removed zone 1559d can be used to better house the evaporable material 302 within the housing 320 and / or simplify the control of the airflow through the housing 320, which requires fewer and / or smaller components.

[0415] In some implementations, the heating element 1542 may be further modified to control the flow of current through different areas of the heating element 1542. For example, specific patterns of perforations, holes, facets, cuts, and / or the like may be provided on the heating element 1542 such that current flows through the heating element 1542 in an identifiable manner. Thus, in relevant implementations, the controller 104 of the steam generator body 110 may be configured to measure (e.g., via sensor 113) and / or identify the housings 120, 220, 320, as described herein, based on the characteristics of the current flowing through the heating element 1542.

[0416] A heating element 342 in the form of a continuous loop can create a conductive path around the heating element 342. The continuous loop shape increases the efficiency of the heating element 342, and thereby increases the efficiency of the steam generator device 100 utilizing such a structure. However, for inductors (see, for example, those via coils wound in multiple turns around a region near the periphery of the heating element 342)... Figure 5D The efficiency improvement can be even greater in a system where the inductor 543 inductively heats the heating element 342.

[0417] In other implementations, induction coils not wound around the periphery of the heating element 342 can be used, making it easier to manufacture each heating element 342 and / or housing 320. For example, induction coils can be placed in different areas near the periphery of the heating element 342 but not completely wound around these areas, thus achieving an efficient system without requiring a complete conductive path around the heating element 342 (see, for example...). Figures 5A to 5C , Figures 11A to 11O , Figures 12A to 12E , Figures 13A to 13G , Figures 14A to 4C According to this implementation, each heating element 342 and / or housing 320 can be manufactured such that the ends of the heating elements 342 are connected at the joint position 345 without interlocking or welding, which can make manufacturing more efficient and / or cheaper.

[0418] In this regard, the non-cylindrical housing 320 and the receptacles 118, 218 configured to receive the non-cylindrical housing 320 can have additional advantages not present in conventional cylindrical-based systems. For example, the non-cylindrical housing 320 configured to be fitted into the corresponding receptacles 118, 218 in only one or two orientations allows certain components of the steam generator bodies 110, 210 and housing 320 to be positioned in a specific orientation each time. Thus, in order to benefit from cheaper manufacturing without the need for interlocking or welding, while still increasing efficiency, each heating element 342 and / or housing 320 can be manufactured such that the connection position 345 is located in a specific known position, such as on one of the shorter sides or one of the longer sides of the housing 320. The placement of the connection position 345 can be advantageous if it is located away from the drive circuit system 143 (such as an induction coil configured to generate an electromagnetic field). In some implementations, the connector position 345 can be considered as an off-axis location on the principal plane of the electromagnetic field generated by the induction coil and / or a location outside the periphery of each induction coil. If the connector position 345 is instead located near the drive circuit system 143 (e.g., within the principal plane of the electromagnetic field generated by the induction coil and / or within the periphery of the induction coil), this will reduce the coupling efficiency between the induction coil and the heating element 342, and thus reduce the efficiency of the entire system.

[0419] In some implementations, the heating element 342 may be fabricated with a structure optimized and / or tuned to result in the desired coupling with the induction coil. For example, a simple structure may be made for the heating element 342 that couples very well with the induction coil, but ultimately causes the heating element 342 to reach excessively high temperatures, thereby burning the vaporizable material 302. In some implementations, this problem may only exist in certain areas of the vaporizer material 302, and it is therefore beneficial to absorb and / or distribute energy more uniformly across the heating element 342. Thus, in some implementations, the heating element 342 may be perforated and / or cut (e.g., via laser) to adjust its coupling efficiency, such as by creating a tortuous path through which eddy currents flow through the heating element 342.

[0420] In an example implementation, the heating element 342 is fabricated to comprise an aluminum alloy or other metal, such as aluminum foil, which may be in the range of 50 μm to 150 μm thick (e.g., 50 μm to 100 μm, 60 μm to 80 μm, 70 μm to 90 μm, 75 μm to 85 μm) and optionally about 80 μm thick. In some implementations, the heating element 342 may comprise a backing metal, which can increase the structural integrity and / or rigidity of a housing manufactured with this structure, relative to the structural integrity of a shape formed solely of certain metals (e.g., aluminum). For example, the backing metal may comprise a metal layer disposed within at least one paper layer, such that the metal layer is in direct contact with the evaporable material 302 and / or provides better heat transfer to the evaporable material 302, and may optionally be disposed (e.g., sandwiched) between two paper layers. In such implementations, the metal layer can be in the range of 3 μm to 15 μm thick (e.g., 5 μm to 10 μm, 6 μm to 8 μm thick) and optionally about 6.5 μm thick. In related implementations, the paper layer and the metal layer can be sized such that the total thickness of the heating element 342 is in the range of 50 μm to 150 μm thick (e.g., 50 μm to 100 μm, 60 μm to 80 μm, 70 μm to 90 μm, 75 μm to 85 μm thick) and optionally about 80 μm thick. Therefore, the paper layer can be in the range of 35 μm to 145 μm thick (e.g., 40 μm to 100 μm, 50 μm to 70 μm, 55 μm to 75 μm, 60 μm to 80 μm, 65 μm to 75 μm thick) and optionally about 70 μm thick. The total thickness of the heating element 342 can be measured including or excluding the thickness of any covering material 322 wound around the heating element 342, as described herein. For example, the covering material 322 on the exterior of the heater portion 341 and the mouthpiece portion 330 and / or connecting the heater portion 341 and the mouthpiece portion 330 may or may not be included in the thickness measurements described herein. For example, the covering material 322 may be made of one or more of cardboard, corrugated materials (such as cardboard or paper), tobacco paper, heat-resistant plastics, non-wood plant fibers (such as flax, sisal, straw and / or Spanish grass) and / or the like.

[0421] Using a thinner metal can achieve increased coupling efficiency and / or higher temperatures for the heating element 342 with lower total energy. This metal may comprise an aluminum alloy, such as aluminum foil. In other implementations, the metal may comprise another alloy, such as Invar. In some implementations, the heating element 342 may be formed of a cladding metal that can take advantage of the benefits of different metals. For example, the heating element 342 may comprise a cladding metal formed of an aluminum alloy and stainless steel, which can take advantage of the higher coupling efficiency of stainless steel and the higher heat transfer of aluminum.

[0422] In implementations where the heating element 342 includes a backing metal comprising an outer paper layer and an inner metal layer, or is included within the backing metal, additional material may be provided between the metal layer of the heating element 342 and the evaporable material 302. For example, a reconstituted tobacco layer may be disposed between the metal layer of the heating element 342 and the evaporable material 302. Placing the additional material layer between the heating element 342 and the evaporable material 302 can provide a buffer for unwanted substances that have evaporated and / or formed into an aerosol for inhalation by a user. Specifically, when the evaporable material 302 is heated, the additional material layer may absorb substances (e.g., liquids) from the evaporable material 302. For example, if an adhesive is used to shape the heating element 342, the additional material can provide the benefit of absorbing any adhesive or other materials from the metal layer and / or the evaporable material 302. In other implementations, additional material (e.g., a reconstituted tobacco layer) may be additionally or alternatively disposed between the metal layer of the heating element 342 and the outer paper layer. Such implementations can similarly provide the benefit of absorbing any adhesive or other materials from the metal layer and / or the outer paper layer. For example, if adhesive is applied to the outer paper layer, the additional material layer can absorb any adhesive that detaches from the paper layer, providing a buffer against any burning or degradation of the adhesive caused by heat generated by the metal layer, and / or the like. In some implementations, multiple paper layers may be provided outside and / or inside the metal layer of the heating element 342.

[0423] In some implementations, one or more paper layers, outside and / or inside the metal layer of the heating element 342, may be coated with a material configured to absorb liquid from the evaporable material 302 and / or formed from such material to reduce the occurrence of any liquid leaving the cartridge 320 (e.g., remaining as residue in the vaporizer bodies 110, 210). For example, the paper material layer outside the metal layer may be coated with a liquid-repellent and / or liquid-impermeable material (or at least having lower liquid permeability than typical paper materials used in cigarettes), such that the flow direction of any liquid from the evaporable material 302 can be controlled (e.g., so that liquid does not leak out of the periphery of the heating element 342 and / or the cartridge 320). In such implementations, any liquid from the evaporable material 302 may be retained within the cartridge 320 itself, for example, by using inserts (e.g., filters) and / or end caps (such as those described herein) at or near the proximal end 341a and / or the distal end 341b of the heater portion.

[0424] Although the backing metal is described as containing paper or reconstituted tobacco, other materials may be used instead, such as corrugated materials (e.g., cardboard or paper), tobacco paper, heat-resistant plastics (e.g., PET), cellulose acetate, non-wood plant fibers (e.g., flax, sisal, straw, and / or Spanish grass) and / or similar materials, and for simplicity, only paper is described herein. Although the various material layers are described as being inside or outside, additional materials may be present inside or outside the respective materials described. For example, if the heating element 342 includes or is included within the backing metal comprising an outer paper layer and an inner metal layer, additional materials, such as additional covering material 122 and / or covering material 322 extending to the exterior of the mouthpiece portion 330 of the heater portion 341, may be provided on the exterior of the outer paper layer when the cartridge 320 is finally assembled. In various implementations that include a heating element 342 formed as a metal heating stage, the heating element 342 may be configured to heat air passing outside or near the casing 320 before the air enters the casing 320 and travels through the evaporable material 302.

[0425] like Figure 3 As illustrated, the nozzle portion 330 may include an insert 324 encased in a covering material 322 or another housing or material layer. The covering material 322 may be similar to... Figures 1A to 1B The outer layer (e.g., covering material 122). For example, covering material 322 may be made of one or more of the following materials: paper materials (such as cardboard), corrugated materials (such as cardboard or paper), tobacco paper, heat-resistant plastics (e.g., PET), non-wood plant fibers (such as flax, sisal, straw, and / or Spanish grass), and / or similar materials. Insert 324 may be similar to Figures 1A to 1BInsert 124. For example, insert 324 may be made of one or more of the following materials: paper materials (such as cardboard), corrugated materials (such as cardboard or paper), tobacco paper, heat-resistant plastics (e.g., PET), cellulose acetate, non-wood plant fibers (such as flax, sisal, straw and / or Spanish grass) and / or similar materials.

[0426] Insert 324 and / or a material layer (e.g., covering material 322) may extend between the proximal end 330a and the distal end 330b of the nozzle portion, and the total distance between these two ends may be referred to as the length of the nozzle portion 330. Similar to the heater portion 341, the nozzle portion 330 may include a shorter nozzle portion 330 depth transverse to its length and a longer nozzle portion 330 width transverse to both its length and depth. These dimensions may extend along the same axis as the heater portion 341.

[0427] like Figure 3 As illustrated, the insert 324 may include a plurality of airflow outlet channels 326 extending from a plurality of corresponding vapor inlets 335 at the distal end 330b of the mouthpiece portion to a plurality of corresponding airflow outlets 328 at the proximal end 330a of the mouthpiece portion. The airflow outlet channels 326 thereby form a fluid connection between the heater portion 341 and the airflow outlets 328, allowing vapor generated in the heater portion 341 to be drawn towards the user at the proximal end 330a of the mouthpiece portion and ultimately exit as an inhalable aerosol from the airflow outlets 328. Near the distal end 330b of the mouthpiece portion (at least closer than the proximal end 330a of the mouthpiece portion), the insert 324 may also include a plurality of bypass channels 338 extending from a corresponding bypass air inlet to a corresponding bypass outlet, thereby forming a fluid connection between the airflow outlet channels 326 and the ambient air. In some implementations, the airflow outlet channel 326 and / or bypass channel 338 can be created during the manufacturing process by laser cutting through the wall of the insert 324. Although two airflow outlet channels 326 are shown, more or fewer airflow outlet channels 326 may exist. Although one insert 324 is shown extending along most of the length of the nozzle portion 330, additional inserts 324 may exist and / or inserts 324 may extend along less than half the length of the nozzle portion 330.

[0428] The heater portion 341 may include one or more housing inlets (e.g., through-holes) at the distal end 341b of the heater portion, which are configured to allow external air (i.e., outside the housing 320, such as ambient air) to enter a volume at least partially defined by the heating element 342. In some implementations, the volume at least partially defined by the heating element 342 may be referred to as a heating chamber, as this volume is the physically defined location where heating occurs. The heating chamber may be in fluid communication with the proximal end 341a of the heater portion, which may include one or more outlets. Thus, one or more outlets at the proximal end 341a of the heater portion may be in fluid communication via the heating chamber with one or more housing inlets at the distal end 341b of the heater portion.

[0429] When a user draws in at the proximal end 330a of the nozzle portion 330, this causes outside air to enter one or more housing inlets (e.g., through holes) at the distal end 341b of the heater portion, and causes ambient air to enter multiple bypass air inlets 329 approximately simultaneously. The outside air entering at the distal end 341b of the heater portion can then travel through the evaporable material 302 as it is heated to carry away the evaporated material (also referred to as “vapor”) generated in the heating chamber, which contains at least a portion of the volume defined by the heating element 342. Simultaneously, the air entering the multiple bypass air inlets 329 can then travel through multiple bypass channels 338 and exit their respective bypass outlets 327, thereby entering their respective airflow outlet channels 326. Air carried by the heating chamber (containing at least a portion of the volume defined by the heating element 342) through the evaporating material 302 can then travel through one or more outlets at the proximal end 341a of the heater section and into a plurality of vapor inlets 335 at the distal end 330b of the nozzle section, thereby entering a plurality of airflow outlet channels 326. As the vapor and air from the heater section 341 traverse the plurality of airflow outlet channels 326, they mix with ambient air entering through a plurality of bypass air inlets 329 to form an inhalable aerosol. The area where mixing and / or condensation occurs may be referred to as a condensation chamber. Thus, each of the plurality of airflow outlet channels 326 may contain one or more condensation chambers configured to condense the carried vapor and ambient air to form at least a portion of the inhalable aerosol. For example, at least a portion of one or more airflow outlet channels may contain one or more condensation chambers. In some implementations, all or most of the airflow outlet channels 326 may contain one or more condensation chambers. Thus, in some implementations, a portion of at least one airflow outlet channel 326 may not contain at least one condensation chamber. In some implementations, the condenser chamber (e.g., the area where mixing and / or condensation occur) may be a component and / or part of a space separate from and / or outside the airflow outlet passage 326. The inhalable aerosol ultimately flows out from a plurality of airflow outlets 328 at the proximal end 330a of the mouthpiece portion and into the user's mouth. Thus, the plurality of airflow outlets 328 may be in fluid communication with at least one of the corresponding condenser chambers of the plurality of airflow outlets 328, and / or be configured to deliver the inhalable aerosol to the user. Commonly, the paths of air, vapor, and inhalable aerosol within the housing 320 may be referred to as the airflow path of the housing 320. The overall airflow path of the vaporizer device comprising the housing 320 is further defined by the vaporizer body, which is described in more detail below.Although the flow of “air” is described herein, depending on its location within or even outside the housing 320, “air” may contain other substances, such as gaseous and / or condensed materials suspended in a mass of stationary or moving air or in some other gas carrier (e.g., aerosol), liquids or solids that have at least partially transformed into the gaseous phase (e.g., evaporable materials) and / or the like.

[0430] This method of generating inhalable aerosols can be advantageous because it provides a larger fluid volume in which the aerosol can form and cool. For example, providing two independent airflow outlet channels 326 within the mouthpiece portion 330 increases the total fluid volume in which the aerosol can form and cool compared to a single airflow outlet channel, while still providing a smaller fluid volume that is easier to control, providing better intake restriction, and allowing a larger overall portion of the vapor to mix independently with ambient air.

[0431] Although depicted as a generally flattened cylinder, the cross-section of the nozzle portion 330 and / or the heater portion 341 can have different shapes. For example, in some implementations, the cross-section of the nozzle portion 330 and / or the heater portion 341 can be similar to... Figures 8A to 8F One or more of the cross sections. The cross section may be located at any position between the respective distal and proximal ends of each of the nozzle portion 330 and / or heater portion 341.

[0432] Although the heater section 341 and the nozzle section 330 are in Figure 3 They are drawn separately, but they can be combined, such as through one or more outer layers (e.g., similar to...). Figures 1A to 1B The covering material 122). For example, the layer / covering material may be made of one or more of the following: paper materials (such as cardboard), corrugated materials (such as cardboard or paper), tobacco paper, heat-resistant plastics (e.g., PET), non-wood plant fibers (such as flax, sisal, straw, and / or Spanish grass), and / or similar materials. Individually, in some implementations, more or fewer parts and / or features may be present in the heater portion 341 and / or the mouthpiece portion 330, the parts and / or features of the heater portion 341 and / or the mouthpiece portion 330 may be arranged in different locations and / or take different physical forms, and / or the parts of the heater portion 341 and the mouthpiece portion 330 may be interchangeable.

[0433] Although various airflow paths are depicted as forming through a single insert 324, more than one insert 324 and / or additional or alternative components may exist within the nozzle portion 330, defining the airflow path. Furthermore, while multiple or single instances of various features and components are described, more or fewer instances may be provided. Moreover, although the various features and components defining the airflow path are depicted and described as being in a specific location and taking a specific shape, other locations and / or shapes are contemplated. For example, although the bypass channel 338 is depicted as being defined in a direction approximately parallel to the depth of the nozzle portion 330, in some implementations, the bypass channel 338 may be angled downwards (i.e., forming an angle below the first transverse axis). For example, the bypass channel 38 may be angled, such as upwards and / or downwards and / or towards at least one vapor inlet 335 relative to the width of the housing 120. This can introduce more turbulence into the airflow path and promote better mixing of air and vapor. Various implementations of these alternative housing configurations are described in more detail below.

[0434] Figures 4A to 4X Cross-sectional schematic diagrams are drawn illustrating various implementations of steam turbine devices 400a to 400q consistent with the implementation of the current subject. For simplicity only, some components of steam turbine devices 400a to 400q are not shown. Furthermore, these steam turbine devices 400a to 400q can be... Figures 1A to 1B Steam generator devices 100a, 100b Figure 2 Steam generator device 200 and / or Figure 3 The implementation of one or more components of the housing 320.

[0435] like Figures 4A to 4B As shown in the illustration, the steam generator apparatus 400, 400a may include a steam generator body 410 and a casing 420 for containing evaporable material 402. Figure 4B The steam generator devices 400 and 400a shown in the figure are along... Figure 4A The cross-section AA is cut off. As illustrated, the steam generator body 410 may include a retainer assembly 458 and one or more sensors 413. The retainer assembly 458 may include a frame 447 defining a housing 418, and may optionally include a plurality of ridges 446 within the housing. Figure 4AAs illustrated, outside the frame 447 and the housing 418, the holder assembly 458 may include or otherwise couple to one or more inductors 443 and / or one or more flux concentrators 448. In some implementations, each of the one or more inductors 443 may include an induction coil configured to generate an electromagnetic field. In some implementations, each of the one or more flux concentrators 448 may include a magnetic material (e.g., a ferrite material) configured to control and / or guide the electromagnetic field generated by the respective inductor 443, such as by altering the magnetic properties of the field. In some implementations, each of the one or more flux concentrators 448 may include nanocrystalline materials, nanometallic materials, and / or the like. Although various implementations are described with reference to a holder assembly 458 including inductors 443 and / or flux concentrators 448, it will be understood that such a configuration of the holder assembly 458 is not required. In some implementations, inductor 443 and / or flux concentrator 448 may be fixed to or within other components of the vaporizer body 410 that do not define the housing 418. For example, inductor 443 may be fixed to or within the holder assembly 458, and flux concentrator 448 may be fixed to or within other components of the vaporizer body 410 outside the holder assembly 458 (e.g., components further away from the housing 418 and closer to the outer shell of the vaporizer body 410). Alternatively, inductor 443 and flux concentrator 448 may be fixed to or within other components of the vaporizer body 410 outside the holder assembly 458.

[0436] In some implementations, the plurality of ridges 446 may be configured to hold the housing 420 within the receiver 418, for example, by applying a force to the heater portion 441 of the housing 420. In some implementations, the housing 420 may be large enough to apply a force in the opposite direction to the force of the plurality of ridges 446, potentially causing slight deformation of the heater portion 441. As illustrated, the plurality of ridges 446 may be located on one or both of the longitudinal and transverse walls of the housing receiver 418. Although the plurality of ridges are illustrated as protrusions, other geometries may be used.

[0437] As illustrated, the housing 420 may include a nozzle portion 430 and a heater portion 441 within one or more layers of material (illustrated as covering material 422). The housing 420 may extend between a proximal end 420a and a distal end 420b, wherein the dimension between the two is the length of the housing 420. The depth of the housing 420 is transverse to the length of the housing 420 and... Figure 4A The diagram is shown in the middle (from left to right). The width of the box 420 is transverse to both the length and depth of the box 420, and as shown... Figure 4B The image is shown in the middle (from left to right).

[0438] The heater section 441 may include one or more heating elements 442 that at least partially define a volume in which the evaporable material 402 is held. The heating elements 442 may be configured to heat the evaporable material 402 to generate vapor. As described herein, heat may be generated by induction, but conduction and / or convection heating may also be provided. For example, eddy currents may be induced in the heating element 442 via inductance, which in turn causes the heating element 442 to heat up. If the evaporable material 402 is in direct contact with the heating element 442, the evaporable material 402 may be heated by conduction heating at the point of direct contact. Alternatively and additionally, the heat generated by the heating element 442 may be absorbed by air traveling along or near the heating element 442 and distributed to portions of the evaporable material 402 that are not in physical contact with the heating element 442, thereby heating the evaporable material 402 by convection heating. The volume in which the evaporable material 402 is held may be considered a heating chamber. For example, the volume at least partially defined by the heating elements 442 may be referred to as a heating chamber. Therefore, heating element 442 may define at least a portion of the periphery of the heating chamber containing the evaporable material, and in some implementations, substantially the entire periphery. Arrows shown extending from heating element 442 may indicate the direction of heat flow and / or heat transfer from heating element 442, such as a set of relatively horizontal arrows extending from heating element 442 and guiding toward the center of the heating chamber defined by heating element 442 and / or toward the center of the evaporable material 402, as shown. Figures 4A to 4Q Displayed in [the text]. For example... Figure 4P As shown, arrows are also shown extending from heating element 442 along one end of housing 420, indicating the direction of heat flow and / or heat transfer from heating element 442 and guiding towards the center of the heating chamber defined by heating element 442 and / or towards the center of evaporable material 402....
