[0038] This document discloses several detailed exemplary embodiments. However, the specific structural and functional details disclosed herein are merely representative for the purpose of describing exemplary embodiments. These exemplary embodiments may be implemented in many alternative forms and should not be construed as being limited to the exemplary embodiments set forth herein.

[0039] Therefore, while exemplary embodiments are capable of various modifications and alternatives, exemplary embodiments thereof are shown by way of example in the accompanying drawings and will be described in detail herein. However, it should be understood that exemplary embodiments are not intended to be limited to the specific forms disclosed, but rather, exemplary embodiments will encompass all modifications, equivalents, and alternatives thereof. Throughout the description of the accompanying drawings, the same reference numerals denote the same elements.

[0040] It should be understood that when an element or layer is referred to as "in," "connected to," "coupled to," "connected to," "adjacent to," or "covering" another element or layer, it may be directly in, connected to, coupled to, connected to, adjacent to, or cover the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as "directly in," "directly connected to," or "directly coupled to" another element or layer, there are no intermediate elements or layers present. Throughout this specification, the same reference numerals denote the same elements. As used herein, the term "and / or" includes any and all combinations or sub-combinations of one or more of the associated listed items.

[0041] It should be understood that although the terms first, second, third, etc., may be used herein to describe various elements, regions, layers, and / or portions, these elements, regions, layers, and / or portions should not be limited by these terms. These terms are only used to distinguish one element, region, layer, or portion from another. Therefore, without departing from the teachings of the exemplary embodiments, the first element, region, layer, or portion discussed below may be referred to as the second element, region, layer, or portion.

[0042] For ease of description, spatial relative terms (e.g., "below," "below," "lower," "above," and "upper") may be used herein to describe the relationship of one element or feature to another element(s) shown in the accompanying drawings. It should be understood that, in addition to the orientations described in the drawings, spatial relative terms are intended to include different orientations of the device in use or operation. For example, if the device in the drawings is flipped, an element described as "below" or "below" other elements or features will be oriented "above" other elements or features. Thus, the term "below" can include both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptors used herein will be interpreted accordingly.

[0043] The terminology used herein is for the purpose of describing various exemplary embodiments only and is not intended to limit the exemplary embodiments. As used herein, the singular forms “a,” “an,” and “the” are also intended to include the plural forms unless the context clearly indicates otherwise. It will also be understood that the terms “includes,” “including,” “comprises,” and / or “comprising,” when used in this specification, specify the presence of the said feature, integral, step, operation, and / or element, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, and / or groups thereof.

[0044] When the terms “about” and “substantially” are used in relation to numerical values ​​in this specification, they mean that the relevant numerical value includes a tolerance of ±10% around the value, unless otherwise expressly defined.

[0045] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the embodiments pertain. It should also be understood that terms (including those defined in commonly used dictionaries) shall be interpreted as having meanings consistent with their meanings in the relevant technical context and shall not be interpreted as having idealized or overly formal meanings, unless expressly defined herein.

[0046] The hardware may be implemented using processing or control circuitry, such as, but not limited to, one or more processors, one or more central processing units (CPUs), one or more microcontrollers, one or more arithmetic logic units (ALUs), one or more digital signal processors (DSPs), one or more microcomputers, one or more field-programmable gate arrays (FPGAs), one or more system-on-a-chip (SoCs), one or more programmable logic units (PLUs), one or more microprocessors, one or more application-specific integrated circuits (ASICs), or any other device or devices capable of responding to and executing instructions in a defined manner.

[0047] Figure 1 This is a perspective view of the first side of the capsule for an aerosol generating apparatus according to an exemplary embodiment. Figure 2 yes Figure 1 A perspective view of the second side of the cyst. (Refer to...) Figures 1 to 2 The capsule 100 can be configured to be received within an aerosol generating device (e.g., a heated non-combustible aerosol generating device). In the figures, the capsule 100 has a layered structure and a planar form. The proximal end of the capsule 100 may have a curved proximal edge, while the opposite distal end may have a linear distal edge. Furthermore, a pair of linear side edges may connect the curved proximal edge and the linear distal edge. This pair of linear side edges may be parallel to each other. Additionally, the junction between the linear side edges and the linear distal edge may be rounded.

[0048] Although the capsule 100 shown in the accompanying drawings resembles a rectangle with semi-circular ends (e.g., an elongated semi-circle, a semi-circle), it should be understood that other constructions are possible. For example, the shape can be circular, giving the capsule 100 a disc-like appearance. In another example, the capsule 100 can be elliptical or racetrack-shaped. In other cases, the capsule 100 can have a polygonal shape (regular or irregular), including triangles, rectangles (such as squares), pentagons, hexagons, heptagons, or octagons. The layered structure and generally planar form of the capsule 100 facilitates stacking so that multiple capsules can be stored in an aerosol generating device or other receptacles for dispensing new capsules or receiving depleted capsules.

[0049] The capsule 100 includes a first frame 130 and a second frame 140. The first frame 130 and the second frame 140 may have the same shape and size and be aligned such that the outer sidewalls are substantially flush with each other, although exemplary embodiments are not limited thereto. The first frame 130 and the second frame 140 may be formed of suitable polymers such as polyetheretherketone (PEEK), liquid crystal polymer (LCP), and / or ultra-high molecular weight polyethylene (UHMWPE). The first frame 130 and the second frame 140 are connected by connectors 102a, 102b, 102c, 102d, and 102e. Although five connections are shown in the figures, it should be understood that more (e.g., seven) or fewer (e.g., three) connectors may be used. Connectors 102a, 102b, and 102e may be curved proximal edges along the proximal end, while connectors 102c and 102d may be distal linear edges (e.g., adjacent rounded corners) along the opposite distal ends. Connector 102a may be equidistant from, and closer to, connectors 102b and 102e. Furthermore, the distance between connectors 102b and 102e may be equal to the distance between connectors 102c and 102d. Additionally, the distance between connectors 102b and 102c may be equal to the distance between connectors 102e and 102d. Connectors 102a, 102b, 102c, 102d, and 102e will be discussed in further detail herein.

[0050] A first heater 110 is fixed to a first frame 130, and a second heater 120 is fixed to a second frame 140. The first frame 130 and the second frame 140 are non-conductive and electrically isolate the first heater 110 and the second heater 120. A capsule 100 is configured to contain an aerosol-forming substrate, which may be located between the first heater 110 and the second heater 120. The first heater 110 and the second heater 120 are configured to heat the aerosol-forming substrate. As a result of heating, the temperature of the aerosol-forming substrate may increase, and aerosols may be generated. The first heater 110 and the second heater 120 may be in the form of a mesh, a perforated foil, or a combination thereof. For example, both the first heater 110 and the second heater 120 may be in the form of a mesh. In another example, both the first heater 110 and the second heater 120 may be in the form of a perforated foil (e.g., 80, 100, or 250 mesh equivalent). The perforated foil may be mechanically perforated or chemically perforated (e.g., by photochemical processing / etching). In another example, one of the first heater 110 or the second heater 120 may be in the form of a mesh, while the other of the first heater 110 or the second heater 120 may be in the form of a perforated foil. The first heater 110 and the second heater 120 (as well as the first frame 130 and the second frame 140) may be substantially the same size based on the plan view (e.g., ±10% of a given size).

[0051] As discussed herein, an aerosol-forming substrate is a material or combination of materials capable of generating aerosols. An aerosol relates to a substance generated or output by the disclosed, claimed apparatus and its equivalents. The material may include a compound (such as nicotine) wherein, when heated, an aerosol comprising that compound is generated. Heating may be below combustion temperature so that aerosol generation does not involve substantial pyrolysis of the aerosol-forming substrate or the generation of substantial combustion byproducts (if any). Thus, in one exemplary embodiment, no pyrolysis occurs during heating and aerosol generation. In other cases, some pyrolysis and combustion byproducts may be present, but their extent may be considered relatively small and / or merely incidental.

[0052] The aerosol-forming substrate can be a fibrous material. For example, the fibrous material can be a plant-based material. The fibrous material is configured to release a compound upon heating. The compound can be a naturally occurring component of the fibrous material. For example, the fibrous material can be a plant material, such as tobacco, and the released compound can be nicotine. The term "tobacco" includes: any tobacco plant material, including tobacco leaves, tobacco plugs, reconstituted tobacco, compressed tobacco, shaped tobacco, or powdered tobacco, and combinations thereof, derived from one or more tobacco plant species, such as yellow tobacco (Nicotiana rustica) and red tobacco (Nicotiana tabacum).

[0053] In some exemplary embodiments, the tobacco material may include material from any member of the genus *Xanthium*. Furthermore, the tobacco material may include a mixture of two or more different tobacco varieties. Examples of suitable types of tobacco material that may be used include (but are not limited to) flue-cured tobacco, Burley tobacco, dark tobacco, Maryland tobacco, oriental tobacco, rare tobacco, specialty tobacco, and mixtures thereof. The tobacco material may be provided in any suitable form, including but not limited to tobacco sheets, processed tobacco material (such as bulked or expanded tobacco), processed tobacco stems (such as rolled or cut expanded tobacco stems), reconstituted tobacco material, and mixtures thereof. In some exemplary embodiments, the tobacco material is present in the form of substantially dry tobacco substance. Furthermore, in some instances, the tobacco material may be mixed and / or combined with at least one of propylene glycol, glycerin, its derivatives, or combinations thereof.

[0054] This compound can also be a naturally occurring component of medicinal plants that have medically acceptable therapeutic effects.

[0055] Furthermore, the compound may be, or may additionally include, non-naturally occurring additives subsequently introduced into the fibrous material. In one example, the fibrous material may include at least one of cotton, polyethylene, polyester, synthetic fibers, or combinations thereof (e.g., in the form of gauze). In another example, the fibrous material may be a cellulose material (e.g., non-tobacco). In either example, the introduced compound may include nicotine and / or flavoring agents. Flavoring agents may be derived from natural sources, such as plant extracts (e.g., tobacco extracts), and / or from artificial sources. In another example, when the fibrous material includes tobacco, the compound may be, or may additionally include one or more flavoring agents (e.g., mint, peppermint, vanilla). Thus, the compound within the aerosol-forming substrate may include naturally occurring components and / or non-naturally occurring additives. In this regard, it should be understood that the existing level of naturally occurring components in the aerosol-forming substrate can be increased by supplements. For example, the existing level of nicotine in a certain amount of tobacco can be increased by supplementing with an extract containing nicotine.

[0056] In one exemplary embodiment, the first heater 110 and the second heater 120 are configured to perform Joule heating (also known as ohmic / resistance heating) when an electric current is applied thereto. More specifically, the first heater 110 and the second heater 120 may be constructed of conductors (the same or different) and are configured to generate heat when an electric current passes through the conductors. The current may be supplied by a power source (such as a battery) within the aerosol generating apparatus. Suitable conductors for the first heater 110 and the second heater 120 include iron-based alloys (such as stainless steel) and / or nickel-based alloys (such as nickel-chromium). The first heater 110 and the second heater 120 may have a thickness of approximately 0.0010 inches or less (e.g., 0.0005 inches) and a resistance of approximately 0.15-0.5 ohms. Furthermore, although both the first heater 110 and the second heater 120 are shown... Figures 1 to 2 However, it should be understood that in some exemplary embodiments, only one of the first heater 110 or the second heater 120 is needed.

[0057] Current from the power source can be transmitted via electrodes configured to make electrical contact with the first heater 110 and the second heater 120 when the capsule 100 is inserted into the aerosol generating device. In a non-limiting embodiment, the electrodes may be spring-loaded to reinforce engagement with the first heater 110 and the second heater 120 of the capsule 100. Alternatively, movement of the electrodes (e.g., engagement, disengagement) can be achieved by mechanical actuation. The electrodes will be discussed in further detail here. Furthermore, the current supply from the aerosol generating device to the capsule 100 can be manually operated (e.g., button activation) or automatically operated (e.g., inhalation activation).

[0058] Figure 3 yes Figure 1 An exploded view of the cyst body. Figure 4 yes Figure 2 An exploded view of the cyst body. (Refer to...) Figures 3 to 4 The first frame 130 has a first inner surface and a first outer surface. Furthermore, the first frame 130 defines an opening 131 (e.g., a first opening). In one exemplary embodiment, the sidewalls of the opening 131 have opposing linear portions and opposing curved portions, wherein one curved portion is adjacent to first connectors 132a, 132b, and 132e, and another curved portion is adjacent to first connectors 132c and 132d. A first heater 110 is fixed to the first outer surface of the first frame 130 and covers the opening 131. Furthermore, the first heater 110 defines first holes 112a, 112b, 112c, 112d, and 112e. The first holes 112a, 112b, 112c, 112d, and 112e can be positioned and sized such that the first connectors 132a, 132b, 132c, 132d, and 132e are exposed, respectively, when the first heater 110 is fixed to the first frame 130.

[0059] The second frame 140 has a second inner surface and a second outer surface. Furthermore, the second frame 140 defines an opening (e.g., a second opening). The second frame 140 also includes an edge 148 surrounding the opening to define a cavity 141 configured to receive an aerosol-forming substrate. As shown, the inner sidewall of the edge 148 may be flush with the inner sidewall of the opening in the second frame 140 to form a single inner sidewall. In an exemplary embodiment, the inner sidewall of the cavity 141 has opposing linear portions and opposing arcuate portions, wherein one arcuate portion is adjacent to second connectors 142a, 142b, and 142e, while the other arcuate portion is adjacent to second connectors 142c and 142d. A second heater 120 is fixed to the second outer surface of the second frame 140 and covers the cavity 141. Furthermore, the second heater 120 defines second holes 122a, 122b, 122c, 122d, and 122e. The second holes 122a, 122b, 122c, 122d, and 122e can be positioned and sized so that the second connectors 142a, 142b, 142c, 142d, and 142e are exposed respectively when the second heater 120 is secured to the second frame 140.

[0060] The first heater 110 and the second heater 120 can be attached to the first frame 130 and the second frame 140, respectively, using various attachment techniques. For example, the attachment technique may involve injection molding (e.g., insert molding, overmolding). In another example, the attachment technique may involve ultrasonic welding. In other cases, the attachment technique may involve adhesives (e.g., tapes, glues) that are deemed food-safe or otherwise acceptable by regulatory authorities.

[0061] During assembly, after the aerosol forming substrate is placed within cavity 141, the first frame 130 can be connected to the second frame 140. In one exemplary embodiment, as part of this connection, an edge 148 of the second frame 140 is disposed within an opening 131 of the first frame 130. For example, the outer wall of the edge 148 can engage with the sidewall of the opening 131 of the first frame 130. This engagement can be achieved through an interference fit (also referred to as a press fit or friction fit). Alternatively, a gap can be present between the edge 148 and the opening 131 to allow for a relatively small degree of freedom between the second frame 140 and the first frame 130 (e.g., rotation of approximately ±10° or less).

[0062] The first frame 130 includes at least one first connector projecting from a first inner surface of the first frame 130. The at least one first connector of the first frame 130 may be in the form of first connectors 132a, 132b, 132c, 132d, and 132e. Similarly, the second frame 140 includes at least one second connector projecting from a second inner surface of the second frame 140. The at least one second connector of the second frame 140 may be in the form of second connectors 142a, 142b, 142c, 142d, and 142e. The at least one first connector of the first frame 130 is configured to engage with the at least one second connector of the second frame 140 to form at least one connection, such that the first inner surface of the first frame 130 is adjacent to the second inner surface of the second frame 140. At least one connection of the capsule 100 may be in the form of connections 102a, 102b, 102c, 102d, and 102e.

[0063] Figure 5 yes Figure 3 An enlarged view of the first connector of the first frame. (Refer to...) Figure 5Each first connector of the first frame 130 (e.g., first connector 132a) includes a first arm (e.g., first arm 134a) and a first gripping portion (e.g., first gripping portion 136a). The first arm may be coplanar with the first frame 130. The first gripping portion may protrude from a first inner surface of the first frame 130. In an exemplary embodiment, the first connector may be a portion of the first frame 130 in which the first arm (together with its corresponding first gripping portion) extends into a corresponding first hole defined by the first frame 130. In this case, the first arm and the first gripping portion of the first connector may be considered integrally formed with the first frame 130. As shown and discussed in further detail, the first connectors 132a, 132b, and 132e respectively include first arms 134a, 134b, and 134e extending into corresponding first holes defined by the first frame 130. Furthermore, the first connectors 132a, 132b, and 132e each include first gripping portions 136a, 136b, and 136e, which protrude from the first inner surface of the first frame 130. Additionally, the first gripping portions 136a, 136b, and 136e may extend orthogonally relative to the first arm portions 134a, 134b, and 134e, respectively, to form corresponding first bosses.

[0064] Figure 6 yes Figure 3 An enlarged view of the second connector of the second frame. (Refer to...) Figure 6 Each second connector of the second frame 140 (e.g., second connector 142a) includes a second arm (e.g., second arm 144a) and a second gripping portion (e.g., second gripping portion 146a). The second arm may be coplanar with the second frame 140. The second gripping portion may protrude from a second inner surface of the second frame 140. In an exemplary embodiment, the second connector may be a portion of the second frame 140 in which the second arm (together with its corresponding second gripping portion) extends into a corresponding second hole defined by the second frame 140. In this case, the second arm and the second gripping portion of the second connector may be considered integrally formed with the second frame 140. As shown and discussed in further detail, second connectors 142a, 142b, and 142e respectively include second arms 144a, 144b, and 144e extending into corresponding second holes defined by the second frame 140. Furthermore, the second connectors 142a, 142b, and 142e each include second gripping portions 146a, 146b, and 146e, which protrude from the second inner surface of the second frame 140. Additionally, the second gripping portions 146a, 146b, and 146e may extend orthogonally relative to the second arm portions 144a, 144b, and 144e, respectively, to form corresponding second bosses.

[0065] Figure 7 yes Figure 1A plan view showing the connections. (Refer to...) Figure 7 The first frame 130 and the second frame 140 are connected during the assembly of the capsule 100 via multiple connections (e.g., connection 102a). In one exemplary embodiment, at least one first connector of the first frame 130 is configured to interlock with at least one second connector of the second frame 140 to form such a connection (e.g., internal snap-fit ​​connection). For example, as shown, a first gripping portion 136a of the first connector 132a is configured to engage with a second gripping portion 146a of the second connector 142a to form connection 102a. Similarly, a first gripping portion 136b of the first connector 132b is configured to engage with a second gripping portion 146b of the second connector 142b to form connection 102b. It is also shown that a first gripping portion 136e of the first connector 132e is configured to engage with a second gripping portion 146e of the second connector 142e to form connection 102e.

[0066] exist Figure 7 During the formation of connections 102a, 102b, and 102e, the first arms 134a, 134b, and 134e and the second arms 144a, 144b, and 144e can be deflected relative to each other to allow the first gripping portions 136a, 136b, and 136e and the second gripping portions 146a, 146b, and 146e to elastically slide past each other before rebounding, thereby allowing the first flanges of the first connectors 132a, 132b, and 132e to interlock or otherwise engage with the second flanges of the second connectors 142a, 142b, and 142e. In this configuration, the first gripping portions 136a, 136b, and 136e can extend into the second hole defined by the second frame 140, while the second gripping portions 146a, 146b, and 146e can extend into the first hole defined by the first frame 130.

[0067] In a non-limiting embodiment, the height (e.g., protrusion) of the first gripping portions 136a, 136b, and 136e may be equal to or less than the thickness of the second frame 140, so that the first gripping portions 136a, 136b, and 136e do not extend beyond the second outer surface of the second frame 140. Similarly, the height (e.g., protrusion) of the second gripping portions 146a, 146b, and 146e may be equal to or less than the thickness of the first frame 130, so that the second gripping portions 146a, 146b, and 146e do not extend beyond the first outer surface of the first frame 130. Furthermore, when in an interlocked arrangement, the first arms 134a, 134b, and 134e may be parallel to the second arms 144a, 144b, and 144e, respectively, although exemplary embodiments are not limited thereto. While the foregoing discussion relates to... Figure 7 The connections 102a, 102b, and 102e are shown, but it should be understood that this description also applies to... Figure 1Other connections are shown (e.g., connections 102c and 102d). Once assembled, capsule 100 is difficult or impossible to open without damaging the connectors, frame, and / or other aspects of capsule 100. Therefore, capsule 100 is relatively tamper-proof to prevent unauthorized actions by third parties.

[0068] Among other things, the capsule 100 has been described as including a first frame 130 separate from the second frame 140. Alternatively, in some cases, the first frame 130 and the second frame 140 may be manufactured as a single structure configured to fold during assembly, thereby engaging the first connector (e.g., first connector 132a) with the second connector (e.g., second connector 142a). For example, the first frame 130 and the second frame 140 may resemble a clamshell structure, wherein the linear distal edge of the first frame 130 is connected to the linear distal edge of the second frame 140, wherein a thinner integral portion serves as a fold line. In another example, the linear side of the first frame 130 may be connected to the linear side of the second frame 140, wherein a thinner integral portion serves as a fold line. For the clamshell structure, it should be understood that one or more connections (e.g., connections 102b, 102c and / or 102d) may be omitted from the capsule 100.

[0069] Figure 8 This is a perspective view of the first side of another capsule for an aerosol generating apparatus according to an exemplary embodiment. Figure 9 yes Figure 8 A perspective view of the second side of the cyst. (Refer to...) Figure 8-9 The capsule 200 can be configured to be received within an aerosol generating device (e.g., a heated non-combustible aerosol generating device). In the figure, the capsule 200 has a layered structure and a generally flat shape. The proximal end of the capsule 200 may have a curved proximal edge, while the opposite distal end may have a linear distal edge. Furthermore, a pair of linear sides may connect the curved proximal edge and the linear distal edge. This pair of linear sides may be parallel to each other. Additionally, the junction between the linear sides and the linear distal edge may be rounded.

[0070] Although the capsule 200 shown in the figure resembles a rectangle with semi-circular ends (e.g., an elongated semi-circle, a semi-circle), it should be understood that other constructions are possible. For example, the shape can be circular, giving the capsule 200 a disc-like appearance. In another example, the capsule 200 can be elliptical or runway-like. In other cases, the capsule 200 can have a polygonal shape (regular or irregular), including triangles, rectangles (such as squares), pentagons, hexagons, heptagons, or octagons. The layered structure and generally flat form of the capsule 200 facilitate stacking so that multiple capsules can be stored in an aerosol generating device or other container for dispensing new capsules or receiving depleted capsules.

[0071] The capsule 200 includes a first frame 230 and a second frame 240. The first frame 230 and the second frame 240 may have the same shape and size (e.g., based on a plan view) and be aligned such that the outer walls are substantially flush with each other, although exemplary embodiments are not limited thereto. The first frame 230 and the second frame 240 may be formed of suitable polymers such as polyetheretherketone (PEEK), liquid crystal polymer (LCP), and / or ultra-high molecular weight polyethylene (UHMWPE). The first frame 230 and the second frame 240 may be connected by a friction-fit design.

[0072] The first heater 210 is fixed and exposed by the first frame 230. Similarly, the second heater 220 is fixed and exposed by the second frame 240. As will be discussed in detail here, a third frame 250 is disposed between the first heater 210 and the second heater 220 (and between the first frame 230 and the second frame 240). The capsule 200 is configured to contain an aerosol-forming substrate, which may be located within the third frame 250 and between the first heater 210 and the second heater 220. The first heater 210 and the second heater 220 are configured to heat the aerosol-forming substrate. As a result of heating, the temperature of the aerosol-forming substrate may increase, and aerosols may be generated. The first heater 210 and the second heater 220 may be in the form of a mesh, a perforated foil, or a combination thereof. For example, both the first heater 210 and the second heater 220 may be in the form of a mesh. In another example, both the first heater 210 and the second heater 220 may be in the form of a perforated foil (e.g., equivalent to 80, 100, or 250 mesh). In another example, one of the first heater 210 or the second heater 220 may be in the form of a mesh, while the other of the first heater 210 or the second heater 220 may be in the form of a perforated foil.

[0073] In one exemplary embodiment, the first heater 210 and the second heater 220 are configured to perform Joule heating (also known as ohmic / resistance heating) when an electric current is applied thereto. More specifically, the first heater 210 and the second heater 220 may be constructed of conductors (the same or different) and are configured to generate heat when an electric current passes through the conductors. The current may be provided by a power source (such as a battery) within the aerosol generating apparatus. Suitable conductors for the first heater 210 and the second heater 220 include iron-based alloys (such as stainless steel) and / or nickel-based alloys (such as nickel-chromium). The thickness of the first heater 210 and the second heater 220 may be approximately 0.0010 inches or less (e.g., 0.0005 inches), and the resistance is approximately 0.15–0.2 ohms. Furthermore, although both the first heater 210 and the second heater 220 are... Figure 8-9 As shown, but it should be understood that in some exemplary embodiments, only one of the first heater 210 or the second heater 220 is required.

[0074] When the capsule 200 is inserted into the aerosol generating device, current from the power source can be transmitted through electrodes configured to make electrical contact with the first heater 210 and the second heater 220. In a non-limiting embodiment, the electrodes may be spring-loaded to reinforce engagement with the first heater 210 and the second heater 220 of the capsule 200. Additionally, movement of the electrodes (e.g., engagement, disengagement) can be achieved by mechanical actuation. The electrodes will be discussed in further detail here. Furthermore, the current supply from the aerosol generating device to the capsule 200 can be manually operated (e.g., button activation) or automatically operated (e.g., inhalation activation).

[0075] Figure 10 yes Figure 8 An exploded view of the cyst body. Figure 11 yes Figure 9 An exploded view of the cyst body. (Refer to...) Figure 10-11 The first frame 230 has a first inner surface and a first outer surface. Furthermore, the first frame 230 defines a first opening 231. In one exemplary embodiment, the sidewalls of the first opening 231 have opposing linear portions and optionally opposing curved portions, one curved portion being adjacent to a proximal end of the first frame 230, and the other curved portion being adjacent to a relatively distal end of the first frame 230. A first heater 210 may be fixed to the first inner surface of the first frame 230 so as to be exposed through the first opening 231. Alternatively, the first heater 210 may also be considered as covering the first opening 231.

[0076] The second frame 240 has a second inner surface and a second outer surface. Furthermore, the second frame 240 defines a second opening 241. In one exemplary embodiment, the sidewalls of the second opening 241 have opposing linear portions and optionally opposing curved portions, one curved portion adjacent to a proximal end of the second frame 240 and the other curved portion adjacent to a relatively distal end of the second frame 240. A second heater 220 may be fixed to the second inner surface of the second frame 240 so as to be exposed by the second opening 241. Alternatively, the second heater 220 may also be considered as covering the second opening 241. The size and shape of the second opening 241 may correspond to (e.g., mirror) the size and shape of the first opening 231.

[0077] The third frame 250 defines a cavity 251 configured to receive an aerosol-forming substrate. In one exemplary embodiment, the sidewalls of the cavity 251 have opposing linear portions and opposing curved portions, one curved portion adjacent to the proximal end of the third frame 250, and the other curved portion adjacent to the opposing distal end of the third frame 250. Based on the plan view, the third frame 250 may be substantially the same size as the first heater 210 and the second heater 220 (e.g., given a size ±10%). In addition to the structural materials of the first frame 230 and the second frame 240, the third frame 250 may also be formed of other suitable materials, such as ceramics, sintered glass, and / or reinforcing fibers (e.g., cardboard).

[0078] The first heater 210 and the second heater 220 can be attached to the first frame 230 and the second frame 240, respectively, using various attachment techniques. For example, the attachment technique may involve injection molding (e.g., insert molding, overmolding). In another example, the connection technique may involve ultrasonic welding. In other cases, the connection technique may include adhesives (e.g., tape, glue) deemed food-safe or otherwise acceptable by regulatory agencies. Alternatively, instead of individual connection techniques, the first heater 210 and the second heater 220 can be clamped to the third frame 250 (or otherwise constrained) by the first frame 230 and the second frame 240, respectively.

[0079] The first frame 230 includes at least one first connector projecting from a first inner surface of the first frame 230. The at least one first connector of the first frame 230 may be in the form of a first connector 238. In one exemplary embodiment, the first connector 238 may extend along the edge of the first inner surface of the first frame 230 in the form of a ridge (e.g., a first ridge). Although the first connector 238 is shown as being separated into multiple discrete structures (e.g., four discrete structures), it should be understood that the exemplary embodiments are not limited thereto. For example, alternatively, the first connector 238 may be a single, continuous structure extending along the edge to completely surround the first inner surface of the first frame 230.

[0080] Similarly, the second frame 240 includes at least one second connector projecting from the second inner surface of the second frame 240. At least one second connector of the second frame 240 may be in the form of a second connector 248. In one exemplary embodiment, the second connector 248 may extend along the periphery of the second inner surface of the second frame 240 in the form of an offset or spaced-apart ridge (e.g., a second ridge). Although the second connector 248 is shown as being separated into multiple discrete structures (e.g., four discrete structures), it should be understood that the exemplary embodiments are not limited thereto. For example, alternatively, the second connector 248 may be a single, continuous structure extending along the periphery to completely surround the second inner surface of the second frame 240.

[0081] For assembly of the capsule 200, after the aerosol forming substrate is placed within the cavity 251 of the third frame 250, the first frame 230 can be connected to the second frame 240. In this case, when the first frame 230 is connected to the second frame 240, the third frame 250 will be sandwiched between the first heater 210 and the second heater 220. During assembly, at least one first connector of the first frame 230 is configured to engage with at least one second connector of the second frame 240 to form at least one connection (e.g., four connections). In an exemplary embodiment, the inner sidewall of the first connector 238 is configured to frictionally engage with the outer sidewall of the second connector 248. Furthermore, the inner sidewall of the first connector 238 may have a sloped surface to facilitate engagement with the outer sidewall of the second connector 248.

[0082] The height of the first connector 238 (e.g., the degree to which it protrudes from the first inner surface) can correspond to the height of the second connector 248 (e.g., the degree to which it protrudes from the second inner surface). Furthermore, the combined thickness of the first heater 210, the second heater 220, and the third frame 250 can correspond to the height of the second connector 248. Therefore, when assembling the capsule 200, the first connector 238 of the first frame 230 can contact the second inner surface (e.g., the offset surface) of the second frame 240. Furthermore, the thickness of the first connector 238 of the first frame 230 can correspond to the distance by which the second connector 248 is offset from the edge of the second frame 240. Therefore, when the capsule 200 is assembled, the outer wall of the first frame 230 can be substantially flush with the outer wall of the second frame 240.

[0083] Figure 12 This is a perspective view of the first side of another capsule for an aerosol generating apparatus according to an exemplary embodiment. Figure 13 yes Figure 12 A perspective view of the second side of the cyst. (Refer to...) Figure 12-13 The capsule 300 can be configured to be received within an aerosol generating device (e.g., a heated non-combustible aerosol generating device). Figure 12-13 The cyst 300 in the middle can be similar to Figure 8-9 The capsule 200 differs in its frame connection type, which will be discussed in detail herein. In the figure, capsule 300 has a layered structure and a generally flat form. The proximal end of capsule 300 may have a curved proximal edge, while the opposite distal end may have a linear distal edge. Furthermore, a pair of linear sides may connect the curved proximal edge and the linear distal edge. This pair of linear sides may be parallel to each other. Additionally, the junction between the linear sides and the linear distal edge may be rounded.

[0084] Although the capsule 300 shown in the figure resembles a rectangle with semi-circular ends (e.g., an elongated semi-circle, a semi-circle), it should be understood that other constructions are possible. For example, the shape can be circular, giving the capsule 300 a disc-like appearance. In another example, the shape of the capsule 300 can be elliptical or racetrack-like. In other cases, the capsule 300 can have a polygonal shape (regular or irregular), including triangles, rectangles (such as squares), pentagons, hexagons, heptagons, or octagons. The layered structure and generally flat form of the capsule 300 can facilitate stacking so that multiple capsules can be stored in an aerosol generating device or other container for dispensing new capsules or receiving depleted capsules.

[0085] The capsule 300 includes a first frame 330 and a second frame 340. The first frame 330 and the second frame 340 may have the same shape and size (e.g., based on a plan view) and be aligned such that their outer walls are substantially flush with each other, although exemplary embodiments are not limited thereto. The first frame 330 and the second frame 340 may be formed of suitable polymers such as polyetheretherketone (PEEK), liquid crystal polymer (LCP), and / or ultra-high molecular weight polyethylene (UHMWPE). The first frame 330 and the second frame 340 may be joined by a welded arrangement.

[0086] The first heater 310 is fixed and exposed by the first frame 330. Similarly, the second heater 320 is fixed and exposed by the second frame 340. As will be discussed in detail here, the third frame 350 is disposed between the first heater 310 and the second heater 320 (and between the first frame 330 and the second frame 340). The capsule 300 is configured to contain an aerosol-forming substrate, which may be located within the third frame 350 and between the first heater 310 and the second heater 320. The first heater 310 and the second heater 320 are configured to heat the aerosol-forming substrate. As a result of heating, the temperature of the aerosol-forming substrate may increase, and aerosols may be generated. The first heater 310 and the second heater 320 may be in the form of a mesh, a perforated foil, or a combination thereof. For example, both the first heater 310 and the second heater 320 may be in the form of a mesh. In another example, both the first heater 310 and the second heater 320 may be in the form of a perforated foil (e.g., equivalent to 80, 100, or 250 mesh). In another example, one of the first heater 310 or the second heater 320 may be in the form of a mesh, while the other of the first heater 310 or the second heater 320 may be in the form of a perforated foil.

[0087] In one exemplary embodiment, the first heater 310 and the second heater 320 are configured to perform Joule heating (also known as ohmic / resistance heating) when an electric current is applied thereto. More specifically, the first heater 310 and the second heater 320 may be constructed of conductors (the same or different) and are configured to generate heat when an electric current passes through the conductors. The current may be provided by a power source (e.g., a battery) within the aerosol generating apparatus. Suitable conductors for the first heater 310 and the second heater 320 include iron-based alloys (such as stainless steel) and / or nickel-based alloys (such as nickel-chromium). The thickness of the first heater 310 and the second heater 320 may be approximately 0.0010 inches or less (e.g., 0.0005 inches), and the resistance is approximately 0.15-0.2 ohms. Furthermore, although both the first heater 310 and the second heater 320 are... Figure 12-13 As shown, but it should be understood that in some exemplary embodiments, only one of the first heater 310 or the second heater 320 is required.

[0088] When the capsule 300 is inserted into the aerosol generating device, current from the power source can be transmitted through electrodes configured to make electrical contact with the first heater 310 and the second heater 320. In a non-limiting embodiment, the electrodes may be spring-loaded to reinforce engagement with the first heater 310 and the second heater 320 of the capsule 300. Additionally, movement of the electrodes (e.g., engagement, disengagement) can be achieved by mechanical actuation. The electrodes will be discussed in further detail here. Furthermore, the current supply from the aerosol generating device to the capsule 300 can be manually operated (e.g., button activation) or automatically operated (e.g., inhalation activation).

[0089] Figure 14 yes Figure 12 An exploded view of the cyst body. Figure 15 yes Figure 13 An exploded view of the cyst body. (Refer to...) Figure 14-15 The first frame 330 has a first inner surface and a first outer surface. Furthermore, the first frame 330 defines a first opening 331. In one exemplary embodiment, the sidewalls of the first opening 331 have opposing linear portions and optionally opposing curved portions, one curved portion being adjacent to a proximal end of the first frame 330, and the other curved portion being adjacent to a relatively distal end of the first frame 330. A first heater 310 may be fixed to a first inner surface of the first frame 330 so as to be exposed by the first opening 331. Alternatively, the first heater 310 may also be considered as covering the first opening 331.

[0090] The second frame 340 has a second inner surface and a second outer surface. Furthermore, the second frame 340 defines a second opening 341. In one exemplary embodiment, the sidewalls of the second opening 341 have opposing linear portions and optionally opposing curved portions, one curved portion being adjacent to a proximal end of the second frame 340, and the other curved portion being adjacent to a relatively distal end of the second frame 340. The second heater 320 may be fixed to the second inner surface of the second frame 340 so as to be exposed by the second opening 341. Alternatively, the second heater 320 may also be considered as covering the second opening 341. The size and shape of the second opening 341 may correspond to (e.g., mirror) the size and shape of the first opening 331.

[0091] The third frame 350 defines a cavity 351 configured to receive an aerosol-forming substrate. In one exemplary embodiment, the sidewalls of the cavity 351 have opposing linear portions and opposing curved portions, one curved portion adjacent to the proximal end of the third frame 350, and the other curved portion adjacent to the opposing distal end of the third frame 350. Based on the plan view, the third frame 350 may be substantially the same size as the first heater 310 and the second heater 320 (e.g., ±10% of a given size).

[0092] The first heater 310 and the second heater 320 can be attached to the first frame 330 and the second frame 340 respectively using various attachment techniques. For example, the attachment technique may involve injection molding (e.g., insert molding, overmolding). In another example, the connection technique may involve ultrasonic welding. In other cases, the connection technique may include adhesives (e.g., tape, glue) deemed food-safe or otherwise acceptable by regulatory agencies. Alternatively, instead of a separate connection technique, the first heater 310 and the second heater 320 may be clamped to the third frame 350 (or otherwise constrained) by the first frame 330 and the second frame 340 respectively.

[0093] The first frame 330 includes at least one first connector projecting from a first inner surface of the first frame 330. The at least one first connector of the first frame 330 may be in the form of a first connector 338. In one exemplary embodiment, the first connector 338 may extend along the edge of the first inner surface of the first frame 330 in the form of a ridge (e.g., a first ridge). This ridge may define a groove extending along its entire length to form a raised groove or a recessed / recessed ridge. Although the first connector 338 is shown as being separated into multiple discrete structures (e.g., four discrete structures), it should be understood that the exemplary embodiments are not limited thereto. For example, alternatively, the first connector 338 may be a single, continuous structure extending along the edge to completely surround the first inner surface of the first frame 330.

[0094] Similarly, the second frame 340 includes at least one second connector projecting from the second inner surface of the second frame 340. The at least one second connector of the second frame 340 may be in the form of a second connector 348. In one exemplary embodiment, the second connector 348 may extend along the periphery of the second inner surface of the second frame 340 in the form of a ridge (e.g., a second ridge), while being offset or spaced from the edge. This ridge may have a tapered / recessed ridge line, and thus may be referred to as a tapered ridge. Although the second connector 348 is shown as being separated into multiple discrete structures (e.g., four discrete structures), it should be understood that the exemplary embodiments are not limited thereto. For example, alternatively, the second connector 348 may be a single, continuous structure extending along the periphery to completely surround the second inner surface of the second frame 340.

[0095] To assemble the capsule 300, after the aerosol forming substrate is placed within the cavity 351 of the third frame 350, the first frame 330 can be connected to the second frame 340. In this case, when the first frame 330 is connected to the second frame 340, the third frame 350 will be sandwiched between the first heater 310 and the second heater 320. During assembly, at least one first connector of the first frame 330 is configured to engage with at least one second connector of the second frame 340 to form at least one connection (e.g., four connections). In an exemplary embodiment, the concave ridge of the first connector 338 is configured to mate with the tapered ridge of the second connector 348. Furthermore, the welded structure between the first connector 338 and the second connector 348 can be achieved by ultrasonic welding.

[0096] The depth of the groove in the first connector 338 can correspond to the height of the second connector 348 (e.g., the degree to which it protrudes from the second inner surface). Furthermore, the combined thickness of the first heater 310, the second heater 320, and the third frame 350 can correspond to the height of the first connector 338 (e.g., the degree to which it protrudes from the first inner surface). Therefore, when assembling the capsule 300, the first connector 338 of the first frame 330 can contact the second inner surface (e.g., the offset surface) of the second frame 340. Furthermore, when the capsule 300 is assembled, the outer wall of the first frame 330 can be substantially flush with the outer wall of the second frame 340. Figure 16 This is an exploded view of another capsule for an aerosol generating apparatus according to an exemplary embodiment. Figure 16 The cyst 400 in the middle can be similar to Figure 1-7 The capsule 100 differs in detail from the connector, which will be discussed in detail herein. Therefore, the relevant disclosures of common features above should be understood to apply to this section, and may not be repeated for the sake of brevity.

[0097] Figure 16This is an exploded view of a capsule for an aerosol generating apparatus according to an exemplary embodiment. Figure 16 The cyst 400 in the middle can be similar to Figure 1-7 The capsule 100 differs in detail from the connector, which will be discussed in detail herein. Therefore, the relevant disclosures of common features above should be understood to apply to this section, and may not be repeated for the sake of brevity.

[0098] Reference Figure 16 The capsule 400 includes a first frame 430 and a second frame 440. A first heater 410 is fixed to the first frame 430, and a second heater 420 is fixed to the second frame 440. The capsule 400 is configured to accommodate an aerosol-forming substrate 460, which may be located between the first heater 410 and the second heater 420. The aerosol-forming substrate 460 may have a thickness of 0.8-1.2 mm (e.g., 1.0 mm). Regarding the composition, the aerosol-forming substrate may include a ratio of approximately 3:1 to 1.5:1 (e.g., 2:1) of tobacco and glycerin (e.g., 80 mg tobacco and 35 mg glycerin). Furthermore, the tobacco may be in ground form with a particle size of 0.500 mm-0.750 mm, although the example embodiment is not limited to this. The first heater 410 and the second heater 420 are configured to heat the aerosol-forming substrate 460. Figure 16 Both the first heater 410 and the second heater 420 are shown in the figure, but it should be understood that in some exemplary embodiments, only one of the first heater 410 or the second heater 420 is required.

[0099] The first frame 430 has a first inner surface and a first outer surface. Furthermore, the first frame 430 defines an opening (e.g., similar to...). Figure 3 (Opening 131 in the first frame 430). The first heater 410 is fixed to the first outer surface of the first frame 430 and covers the opening. In addition, the first heater 410 may define a first hole, the position and size of which are such that at least one first connector (e.g., first connector 432) is exposed when the first heater 410 is fixed to the first frame 430.

[0100] The second frame 440 has a second inner surface and a second outer surface. Furthermore, the second frame 440 defines an opening (e.g., a second opening). The second frame 440 also includes an edge 448 surrounding the opening to define a cavity configured to receive an aerosol forming substrate 460. As shown, the inner sidewall of the edge 448 may be flush with the inner sidewall of the opening in the second frame 440 to form a single inner sidewall. In an exemplary embodiment, the inner sidewall of the cavity has opposing linear portions and opposing curved portions, one curved portion adjacent to a proximal end of the second frame 440 and the other curved portion adjacent to a relatively distal end of the second frame 440. A second heater 420 is attached to the second outer surface of the second frame 440 and covers the cavity. Furthermore, the second heater 420 may define a second hole positioned and sized to expose at least one second connector (e.g., a second connector 442) when the second heater 420 is attached to the second frame 440.

[0101] During assembly, after the aerosol forming substrate 460 is disposed within the cavity, the first frame 430 can be connected to the second frame 440. In one exemplary embodiment, as part of this connection, an edge 448 of the second frame 440 will be positioned within an opening in the first frame 430. For example, the outer wall of the edge 448 can engage with the sidewall of the opening in the first frame 430. This engagement can be achieved through an interference fit (also referred to as a press fit or friction fit). Alternatively, a gap can be present between the edge 448 and the opening to allow for a relatively small degree of freedom between the second frame 440 and the first frame 430 (e.g., rotation of approximately ±10° or less).

[0102] The first frame 430 includes at least one first connector. This at least one first connector may be in the form of first connectors 432 disposed at four locations on the first frame 430. The second frame 440 includes at least one second connector projecting from a second inner surface of the second frame 440. This at least one second connector may be in the form of second connectors 442 disposed at four locations on the second frame 440 (corresponding to the locations of the first connectors 432 on the first frame 430). The at least one first connector of the first frame 430 is configured to engage with at least one second connector of the second frame 440 to form at least one connection (e.g., four connections) such that the first inner surface of the first frame 430 is adjacent to the second inner surface of the second frame 440. In an exemplary embodiment, the at least one first connector of the first frame 430 and the at least one second connector of the second frame 440 may be identical and mutually oriented structures that complement each other to facilitate the formation of at least one connection.

[0103] Each first connector (e.g., first connector 432) may be in the form of a first gripping portion located adjacent to an opening (e.g., a first aperture) defined by the first frame 430, wherein the aperture has a recessed boss or holder disposed therein. In an exemplary embodiment, the first connector may be considered to be integrally formed with the first frame 430. A first engaging portion of each first connector may protrude from a first inner surface of the first frame 430. In particular, the first engaging portion may include a first neck and a first nose, wherein the first neck protrudes from the first inner surface of the first frame 430, and the first nose extends orthogonally relative to the first neck to form a first boss that overlaps with the first aperture defined by the first frame 430.

[0104] Each second connector (e.g., second connector 442) may be in the form of a second gripping portion located adjacent to an opening (e.g., a second aperture) defined by the second frame 440, wherein the aperture has a recessed boss or holder disposed therein. In an exemplary embodiment, the second connector may be considered to be integrally formed with the second frame 440. A second engaging portion of each second connector may protrude from a second inner surface of the second frame 440. In particular, the second engaging portion may include a second neck and a second nose, wherein the second neck protrudes from the second inner surface of the second frame 440, and the second nose extends orthogonally relative to the second neck to form a second boss that overlaps with the second aperture defined by the second frame 440.

[0105] At least one first connector of the first frame 430 is configured to interlock with at least one second connector of the second frame 440 to form a connection (e.g., internal snap-fit ​​connection) with the capsule 400. For example, to form the connection, a first gripper of the first frame 430 is advanced into a corresponding second opening of the second frame 440, causing a first neck to deflect so that a first nose resiliently engages a corresponding recessed boss in the second opening of the second frame 440. Thus, the first boss of the first connector will interlock or otherwise engage with the corresponding recessed boss of the second connector. Similarly, when such a connection is formed, a second gripper of the second frame 440 is advanced into a corresponding first opening of the first frame 430, causing a second neck to deflect so that a second nose resiliently engages a corresponding recessed boss in the first opening of the first frame 430. As a result, the second boss of the second connector will interlock or otherwise engage with the corresponding recessed boss of the first connector.

[0106] However, instead of mutual engagement of the connectors, it should be understood that, alternatively, the first connector 432 of the first frame 430 may engage with the second connector 442 of the second frame 440 on one side. For example, the gripping part may be omitted from either the first connector 432 or the second connector 442, so that the connector only has an opening and a recessed boss.

[0107] In a non-limiting embodiment, the height (e.g., protrusion) of the first contact portion of the first connector 432 may be equal to or less than the thickness of the second frame 440, so that the first contact portion does not extend beyond the second outer surface of the second frame 440. Similarly, the height (e.g., protrusion) of the second contact portion of the second connector 442 may be equal to or less than the thickness of the first frame 430, so that the second contact portion does not extend beyond the first outer surface of the first frame 430. Furthermore, when in an interlocking arrangement, the first neck of the first connector 432 may be parallel to the second neck of the second connector 442, although exemplary embodiments are not limited thereto.

[0108] Figure 17 This is an exploded view of a capsule for an aerosol generating apparatus according to an exemplary embodiment. Figure 17 The cyst 500 in the middle can be similar to Figure 12-15 The capsule 300 differs in detail from the connector, which will be discussed in detail herein. Therefore, the relevant disclosures of common features above should be understood to apply to this section, and for the sake of brevity, they may not be repeated.

[0109] Reference Figure 17 The capsule 500 includes a first frame 530 and a second frame 540. A first heater 510 is fixed and exposed by the first frame 530. Similarly, a second heater 520 is fixed and exposed by the second frame 540. A third frame 550 is disposed between the first heater 510 and the second heater 520 (and between the first frame 530 and the second frame 540). The capsule 500 is configured to accommodate an aerosol forming substrate 560, which may be within the third frame 550 and between the first heater 510 and the second heater 520. The first heater 510 and the second heater 520 are configured to heat the aerosol forming substrate 560. Although... Figure 17 Both the first heater 510 and the second heater 520 are shown, but it should be understood that in some exemplary embodiments, only one of the first heater 510 or the second heater 520 is required.

[0110] The first frame 530 has a first inner surface and a first outer surface. Furthermore, the first frame 530 defines a first opening (e.g., similar to...). Figure 14 The first heater 510 can be fixed to the first inner surface of the first frame 530 so as to be exposed by the first opening. From different angles, the first heater 510 can also be regarded as covering the first opening.

[0111] The second frame 540 has a second inner surface and a second outer surface. Furthermore, the second frame 540 defines a second opening (e.g., similar to...). Figure 14The second heater 520 can be fixed to the second inner surface of the second frame 540 so as to be exposed by the second opening. From different angles, the second heater 520 can also be regarded as covering the second opening. In an exemplary embodiment, the size and shape of the second opening of the second frame 540 may correspond to (e.g., mirror) the size and shape of the first opening of the first frame 530.

[0112] The third frame 550 defines a cavity 551 configured to receive an aerosol forming substrate 560. In one exemplary embodiment, the sidewalls of the cavity 551 have opposing linear portions and opposing curved portions, one curved portion adjacent to the proximal end of the third frame 550 and the other curved portion adjacent to the opposing distal end of the third frame 550. The third frame 550 may be substantially the same in size as the first heater 510 and the second heater 520 based on a plan view (e.g., ±10% of a given size).

[0113] The first frame 530 includes at least one first connector projecting from a first inner surface of the first frame 530. The at least one first connector of the first frame 530 may be in the form of a first connector 538. In an exemplary embodiment, the first connector 538 may extend along the edge of the first inner surface of the first frame 530 in the form of a ridge (e.g., a first ridge). The ridge may define a groove extending along its entire length, so as to resemble a raised groove or a recessed / wrinkled ridge. Furthermore, or alternatively, the ridge may have a tapered ridge line, and thus may be referred to as a tapered ridge. Although the first connector 538 is shown as being separated into multiple discrete structures (e.g., four discrete structures), it should be understood that the exemplary embodiments are not limited thereto. For example, alternatively, the first connector 538 may be a single, continuous structure extending along the edge to completely surround the first inner surface of the first frame 530.

[0114] Similarly, the second frame 540 includes at least one second connector projecting from the second inner surface of the second frame 540. At least one second connector of the second frame 540 may be in the form of a second connector 548. The second connector 548 of the second frame 540 and the first connector 538 of the first frame 530 are complementary structures configured to mate with each other. In an exemplary embodiment, the second connector 548 may extend along the edge of the second inner surface of the second frame 540 in the form of a ridge (e.g., a second ridge). The ridge may define a groove extending along its entire length, so as to resemble a raised groove or a recessed / wrinkled ridge. Furthermore, or alternatively, the ridge may have a tapered ridge line, and thus may be referred to as a tapered ridge. Although the second connector 548 is shown as being separated into multiple discrete structures (e.g., four discrete structures), it should be understood that the exemplary embodiments are not limited thereto. For example, alternatively, the second connector 548 may be a single, continuous structure extending along the periphery, so as to completely surround the second inner surface of the second frame 540.

[0115] exist Figure 17 In the non-limiting embodiment shown, the first connector 538 of the first frame 530 is separated into four discrete structures, two of which may be raised grooves and the other two of which may be tapered ridges. Conversely, the second connector 548 of the second frame 540 may be separated into four discrete structures, two of which are tapered ridges and the other two of which are raised grooves. The mixed set of raised grooves and tapered ridges of the first frame 530 is configured to mate with the mixed set of tapered ridges and raised grooves of the second frame 540, respectively, during assembly of the capsule 500. It should be understood that various combinations of raised grooves and tapered ridges of the first frame 530 and the second frame 540 are possible.

[0116] When the mixed groups of raised grooves and tapered ridges of each frame are grouped such that the raised grooves are on one linear side and the tapered ridges are on another linear side, as... Figure 17 As shown, the first frame 530 and the second frame 540 can be the same component. In such a case, orienting the first frame 530 and the second frame 540 to face each other and mate will produce a complementary arrangement. Therefore, a single component can be used interchangeably as either the first frame 530 or the second frame 540, thereby simplifying the manufacturing process.

[0117] Figure 18 yes Figure 17 An enlarged view of the second connector of the second frame. (Refer to...) Figure 18The second connector 548 of the second frame 540 can be in the form of a ridge having a shoulder and an inclined portion rising from the shoulder to form a tapered ridge. The tapered ridge can serve to direct energy during assembly (e.g., facilitate soldering). The corresponding first connector 538 of the first frame 530 can be in the form of a ridge similar to a raised groove, wherein the ridge has an edge portion and a descending portion sloping downward from the edge portion to form a V-shaped valley. In an exemplary embodiment of the connection, the inclined portion of the second connector 548 is configured to rest within the descending portion of the first connector 538, while the shoulder of the second connector 548 abuts against the edge portion of the first connector 538. Therefore, the mating surfaces of the first connector 538 and the second connector 548 can be configured in opposite directions to facilitate mating.

[0118] For assembly of the capsule 500, after the aerosol forming substrate 560 is disposed within the cavity 551 of the third frame 550, the first frame 530 can be connected to the second frame 540. In this case, when the first frame 530 is connected to the second frame 540, the third frame 550 will be sandwiched between the first heater 510 and the second heater 520. During assembly, at least one first connector of the first frame 530 is configured to engage with at least one second connector of the second frame 540 to form at least one connection (e.g., four connections). As described above, the raised groove (and / or tapered ridge) of the first connector 538 is configured to mate with the corresponding tapered ridge (and / or raised groove) of the second connector 548. Furthermore, the joinder between the first connector 538 of the first frame 530 and the second connector 548 of the second frame 540 can be achieved by a welding arrangement (e.g., ultrasonic welding). Additionally, when the capsule 500 is assembled, the outer sidewall of the first frame 530 can be substantially flush with the outer sidewall of the second frame 540, although exemplary embodiments are not limited thereto.

[0119] Figure 19 This is an exploded view of a capsule for an aerosol generating apparatus according to an exemplary embodiment. Figure 19 The 500' capsule in the middle can be similar to Figure 17 The cysts within are 500. In particular, Figure 19 The first heater 510', second heater 520', first frame 530', first connector 538', second frame 540', second connector 548', third frame 550', and cavity 551' can be substantially as described above. Figure 17 The description includes the first heater 510, the second heater 520, the first frame 530, the first connector 538, the second frame 540, the second connector 548, the third frame 550, and the cavity 551. Furthermore, although in Figure 19 The document does not specify, but during the assembly process, it is similar to... Figure 17 The aerosol forming substrate 560 will be placed within the capsule 500'. Therefore, the relevant disclosures regarding common features above should be understood to apply to this section, and for the sake of brevity, they may not be repeated. On the other hand, different aspects (e.g., connectors) will be discussed in detail here.

[0120] exist Figure 19 In the non-limiting embodiment shown, the first connector 538' of the first frame 530' is separated into four discrete structures, two of which may be raised grooves and the other two of which may be tapered ridges. Conversely, the second connector 548' of the second frame 540' may be separated into four discrete structures, two of which are tapered ridges and the other two of which are raised grooves. For both the first frame 530' and the second frame 540', the raised grooves may have a flat bottom (as opposed to a V-shaped bottom), although the example embodiment is not limited thereto. During assembly of the capsule 500', the mixed set of raised grooves and tapered ridges of the first frame 530' is configured to mate with the mixed set of tapered ridges and raised grooves of the second frame 540', respectively. It should be understood that the first frame 530' and the second frame 540' may have various combinations of raised grooves and tapered ridges.

[0121] When the mixed groups of raised grooves and tapered ridges of each frame are grouped such that the raised grooves are on one linear side and the tapered ridges are on another linear side, as... Figure 19 As shown, the first frame 530' and the second frame 540' can be the same component. In such a case, orienting the first frame 530' and the second frame 540' to face each other and mate will produce a complementary arrangement. Therefore, a single component can be used interchangeably as either the first frame 530' or the second frame 540', thereby simplifying the manufacturing process. Furthermore, the recesses of the first frame 530', the second frame 54', and the third frame 550' can originate from an injection molding process. In this respect, the size, location, and / or shape of the recesses can differ (or the recesses can be absent entirely), depending on the manufacturing technique.

[0122] Figure 20 This is an exploded view of a capsule for an aerosol generating apparatus according to an exemplary embodiment. Figure 20 The cyst 600 in the middle can be similar to Figure 12-15 The various aspects of the capsule 300, while differing in, for example, the type of frame connection, will be discussed in detail herein. Therefore, the relevant disclosures of common features above should be understood to apply to this section, and for the sake of brevity, may not be repeated.

[0123] Reference Figure 20The capsule 600 includes a first frame 630 and a second frame 640. A first heater 610 is fixed and exposed by the first frame 630. Similarly, a second heater 620 is fixed and exposed by the second frame 640. A third frame 650 is disposed between the first heater 610 and the second heater 620 (and between the first frame 630 and the second frame 640). The capsule 600 is configured to accommodate an aerosol forming substrate 660, which may be within the third frame 650 and between the first heater 610 and the second heater 620. The first heater 610 and the second heater 620 are configured to heat the aerosol forming substrate 660. Although... Figure 20 Both the first heater 610 and the second heater 620 are shown, but it should be understood that in some exemplary embodiments, only one of the first heater 610 or the second heater 620 is required.

[0124] The first frame 630 has a first inner surface and a first outer surface. Furthermore, the first frame 630 defines a first opening (e.g., similar to...). Figure 14 The first heater 610 can be fixed to the first inner surface of the first frame 630 so as to be exposed by the first opening. From different angles, the first heater 610 can also be regarded as covering the first opening.

[0125] The second frame 640 has a second inner surface and a second outer surface. Furthermore, the second frame 640 defines a second opening (e.g., similar to...). Figure 14 The second heater 620 can be fixed to the second inner surface of the second frame 640 so as to be exposed by the second opening. From different angles, the second heater 620 can also be regarded as covering the second opening. In an exemplary embodiment, the size and shape of the second opening of the second frame 640 may correspond to (e.g., mirror) the size and shape of the first opening of the first frame 630.

[0126] The third frame 650 defines a cavity 651 configured to receive an aerosol-forming substrate 660. Furthermore, the third frame 650 defines holes 652 configured to receive connectors of the first frame 630 and the second frame 640 during assembly of the capsule 600. Although six holes 652 are illustrated in relation to the third frame 650 (e.g., six per side for blind holes or six in total for through holes), it should be understood that other numbers (e.g., four) may be suitable. In one exemplary embodiment, the sidewalls of the cavity 651 have opposing linear portions and opposing curved portions, one curved portion adjacent to the proximal end of the third frame 650 and the other curved portion adjacent to the opposing distal end of the third frame 650. The third frame 650 may be substantially the same size as the first heater 610 and the second heater 620 (e.g., ±10% of a given size) based on a plan view.

[0127] The first frame 630 includes at least one connector (e.g., a first connector) projecting from a first inner surface of the first frame 630. For example, the at least one connector of the first frame 630 may be in the form of a projection on the first inner surface. The at least one connector of the first frame 630 may be similar to connector 642 of the second frame 640, which will be discussed in detail here. In an exemplary embodiment, the connector of the first frame 630 may be arranged along the periphery of the first inner surface to align with a hole 652 in the third frame 650 during assembly.

[0128] Similarly, the second frame 640 includes at least one connector (e.g., a second connector) projecting from a second inner surface of the second frame 640. The at least one connector of the second frame 640 may be in the form of a plurality of connectors 642. Although six connectors 642 associated with the second frame 640 are illustrated, it should be understood that other numbers (e.g., four) may be suitable. In one exemplary embodiment, the connectors 642 may be arranged along the periphery of the second inner surface of the second frame 640 to align with corresponding holes 652 in the third frame 650 during assembly. It should be understood that the pattern of the connectors and corresponding holes 652 may vary such that each hole 652 in the third frame 650 receives a connector from both the first frame 630 and the second frame 640, each hole 652 in the third frame 650 receives only one connector from either the first frame 630 or the second frame 640, or a combination thereof.

[0129] In one exemplary embodiment, the first frame 630 and the second frame 640 may be the same component. Therefore, a single component can be used interchangeably as either the first frame 630 or the second frame 640, thereby simplifying the manufacturing process.

[0130] Figure 21 yes Figure 20 An enlarged view of the connector in the second frame. (Refer to...) Figure 21The connector 642 of the second frame 640 can be in the form of a protrusion having a cylindrical body and a conical tip. The conical tip can serve as an energy guide during assembly (e.g., to facilitate soldering). In one exemplary embodiment, the base of the conical tip can be smaller than the diameter of the cylindrical body, thus giving the connector 642 a shoulder. Although not shown, it should be understood that in another case, the base of the conical tip can be the same as the diameter of the cylindrical body, thus eliminating the shoulder of the connector 642. Furthermore, the second heater 620 can provide an opening for each connector 642 of the second frame 640 so that the connector 642 can protrude from it when the second heater 620 is secured to the second inner surface of the second frame 640. Similarly, the first heater 610 can provide an opening for each connector of the first frame 630 so that the connector can protrude from it when the first heater 610 is secured to the first inner surface of the first frame 630.

[0131] To assemble the capsule 600, after the aerosol forming substrate 660 is disposed within the cavity 651 of the third frame 650, the first frame 630 can be connected to the second frame 640. In this case, when the first frame 630 is connected to the second frame 640, the third frame 650 will be sandwiched between the first heater 610 and the second heater 620. During assembly, the connector of the first frame 630 is configured to engage with the corresponding hole 652 of the third frame 650 to form a connection. Similarly, the connector 642 of the second frame 640 is configured to engage with the corresponding hole 652 of the third frame 650 to form a connection. Furthermore, the jointing between the frames via the connectors can be achieved by welding arrangements (e.g., ultrasonic welding) or interference fits. Additionally, the outer walls of the first frame 630, the second frame 640, and the third frame 650 can be substantially flush with each other when the capsule 600 is assembled, although exemplary embodiments are not limited thereto.

[0132] Figure 22 This is an exploded view of a capsule for an aerosol generating apparatus according to an exemplary embodiment. Figure 22 The cyst 700 in the middle can be similar to Figure 17 The capsule 500 differs in how the aerosol-forming substrate is arranged therein, which will be discussed in detail herein. Therefore, the relevant disclosures of common features above should be understood to apply to this section, and for the sake of brevity, they may not be repeated.

[0133] Reference Figure 22The capsule 700 includes a first frame 730 and a second frame 740. A first heater 710 is fixed and exposed by the first frame 730. Similarly, a second heater 720 is fixed and exposed by the second frame 740. The capsule 700 is configured to contain an aerosol forming substrate 760 between the first heater 710 and the second heater 720. The first heater 710 and the second heater 720 are configured to heat the aerosol forming substrate 760. Although Figure 22 Both the first heater 710 and the second heater 720 are shown, but it should be understood that in some exemplary embodiments, only one of the first heater 710 or the second heater 720 is required.

[0134] The first frame 730 has a first inner surface and a first outer surface. Furthermore, the first frame 730 defines a first opening (e.g., similar to...). Figure 14 The first heater 710 may be fixed to the first inner surface of the first frame 730 so as to be exposed by the first opening. From different angles, the first heater 710 may also be regarded as covering the first opening.

[0135] The second frame 740 has a second inner surface and a second outer surface. Furthermore, the second frame 740 defines a second opening (e.g., similar to...). Figure 14 The second heater 720 may be fixed to the second inner surface of the second frame 740 so as to be exposed by the second opening. From different angles, the second heater 720 may also be regarded as covering the second opening. In an exemplary embodiment, the size and shape of the second opening of the second frame 740 may correspond to (e.g., mirror) the size and shape of the first opening of the first frame 730.

[0136] The first frame 730 includes at least one first connector projecting from a first inner surface of the first frame 730. The at least one first connector of the first frame 730 may be in the form of a first connector 738. In an exemplary embodiment, the first connector 738 may extend along the edge of the first inner surface of the first frame 730 in the form of a ridge (e.g., a first ridge). This ridge may define a groove extending along its entire length, so as to resemble a raised groove or a recessed / wrinkled ridge. Furthermore, or alternatively, the ridge may have a tapered ridge line, and thus may be referred to as a tapered ridge. Although the first connector 738 is shown as being separated into multiple discrete structures (e.g., four discrete structures), it should be understood that the exemplary embodiments are not limited thereto. For example, alternatively, the first connector 738 may be a single, continuous structure extending along the edge to completely surround the first inner surface of the first frame 730.

[0137] Similarly, the second frame 740 includes at least one second connector projecting from the second inner surface of the second frame 740. The at least one second connector of the second frame 740 may be in the form of a second connector 748. The second connector 748 of the second frame 740 and the first connector 738 of the first frame 730 are complementary structures configured to mate with each other. In an exemplary embodiment, the second connector 748 may extend along the edge of the second inner surface of the second frame 740 in the form of a ridge (e.g., a second ridge). The ridge may define a groove extending along its entire length, resembling a raised groove or a recessed / wrinkled ridge. Furthermore, or alternatively, the ridge may have a tapered ridge line, and thus may be referred to as a tapered ridge. Although the second connector 748 is shown as being separated into multiple discrete structures (e.g., four discrete structures), it should be understood that the exemplary embodiments are not limited thereto. For example, alternatively, the second connector 748 may be a single, continuous structure extending along the periphery, completely surrounding the second inner surface of the second frame 740.

[0138] exist Figure 22 In the non-limiting embodiment shown, the first connector 738 of the first frame 730 is separated into four discontinuous structures, two of which may be raised grooves and the other two of which may be tapered ridges. Conversely, the second connector 748 of the second frame 740 may be separated into four discontinuous structures, two of which are tapered ridges and the other two are raised grooves. The mixed sets of raised grooves and tapered ridges of the first frame 730 are configured to match, respectively, the mixed sets of tapered ridges and raised grooves of the second frame 740 during assembly of the capsule 700. It should be understood that the first frame 730 and the second frame 740 may have various combinations of raised grooves and tapered ridges.

[0139] In one exemplary embodiment, the first frame 730 and the second frame 740 may be the same component. In such an instance, orienting the first frame 730 and the second frame 740 to face each other for engagement will result in a complementary arrangement. Therefore, a single component can be used interchangeably as either the first frame 730 or the second frame 740, thereby simplifying the manufacturing process.

[0140] For assembling the capsule 700, the first frame 730 can be connected to the second frame 740 after the aerosol forming substrate 760 is disposed between the first frame 730 and the second frame 740. In an exemplary embodiment, the size and shape of the aerosol forming substrate 760 can substantially fill unoccupied space within the capsule 700. For example, the aerosol forming substrate 760 may have portions adjacent to the edges of the capsule 700 (e.g., laterally extending portions) and within the gap between adjacent connectors of the first frame 730 and the second frame 740. Furthermore, the first heater 710 and / or the second heater 720 may have sizes and shapes corresponding to the aerosol forming substrate 760. During assembly, at least one first connector of the first frame 730 is configured to engage with at least one second connector of the second frame 740 to form at least one connection (e.g., four connections). As described above, the raised groove (and / or tapered ridge) of the first connector 738 is configured to engage with the corresponding tapered ridge (and / or raised groove) of the second connector 748. Furthermore, the engagement between the first connector 738 of the first frame 730 and the second connector 748 of the second frame 740 can be achieved by a welding arrangement (e.g., ultrasonic welding). Additionally, the outer wall of the first frame 730 can be substantially flush with the outer wall of the second frame 740 during assembly of the capsule 700, but exemplary embodiments are not limited thereto.

[0141] Figure 23-26 This is a perspective view of a method for manufacturing a capsule for an aerosol generating apparatus according to an exemplary embodiment. (Refer to...) Figure 23 A first sheet 509 (e.g., a first mesh) can be used to produce one or more first heaters (e.g., first heater 510). The first sheet 509 may be in the form of a mesh or foil (e.g., pre-perforated or post-perforated) and is made of a material suitable for Joule heating, as described above. As shown, the first sheet 509 may be cut (e.g., die-cut) to produce one or more heater patterns. Each heater pattern may include a main portion and laterally extending portions that connect the main portion to a peripheral portion of the first sheet 509. Although the main portion of the heater pattern is shown connected to the peripheral portion of the first sheet 509 by four laterally extending portions, it should be understood that the exemplary embodiments are not limited thereto. For example, two laterally extending portions may be sufficient to connect the proximal and distal ends of the main portion of the heater pattern to the peripheral portion of the first sheet 509. In another example, two laterally extending portions may be sufficient to connect the sides of the main portion of the heater pattern to the peripheral portion of the first sheet 509.

[0142] Furthermore, the first sheet 509 may be provided with a plurality of holes 511 to facilitate positioning and movement of the first sheet 509 during the manufacturing process. For example, a first series of holes 511 may be provided along one edge of the first sheet 509, while a second series of holes 511 may be provided along the opposite edge of the first sheet 509. As shown, the first and second series of holes 511 may be arranged parallel to each other along the longitudinal direction of the first sheet 509. As a result, the first sheet 509 may be drawn from a first sheet source (e.g., a reel of the first sheet 509) by one or more drums having circumferentially arranged protrusions configured to engage with the holes 511, and the first sheet 509 advances along a conveying path as the one or more drums rotate.

[0143] The first frame 530 can be manufactured separately and then (e.g., by ultrasonic welding) attached to the main portion of the heater pattern. In another example, the first frame 530 can be manufactured and attached to the main portion of the heater pattern simultaneously. This manufacturing and attachment technique can involve injection molding (e.g., insert molding, overmolding). In one exemplary embodiment, only two laterally extending portions are provided to attach the main portion of the heater pattern (e.g., the proximal and distal ends of the main portion) to the peripheral portion of the first sheet 509, and the first connector of the first frame 530 (e.g., the first connector 538) can be in the form of two discontinuous structures. After the first frame 530 is manufactured and attached to the first sheet 509, the third frame 550 is positioned between the first connectors of the first frame 530.

[0144] Reference Figure 24 The aerosol forming substrate 560 is disposed within a cavity (e.g., cavity 551) of the third frame 550. The aerosol forming substrate 560 may be in a compacted form (e.g., sheet, plate) configured to maintain its shape so that the aerosol forming substrate 560 is uniformly placed within the cavity of the third frame 550. Alternatively, the aerosol forming substrate 560 may be in a loose form (e.g., particles, fibers, fragments, chips, debris) without a predetermined shape, but configured to take the shape of the cavity of the third frame 550 upon introduction.

[0145] refer to Figure 25The second sheet 519 (e.g., a second mesh) can be used to produce one or more second heaters (e.g., a second heater 520). The second sheet 519 can be prepared as described in relation to the first sheet 509 and in a similar manner to produce one or more heater patterns. Furthermore, the second frame 540 can be made and attached to the heater pattern of the second sheet 519 in a manner similar to that of the first frame 530 in making and attaching to the heater pattern of the first sheet 509. In one exemplary embodiment, the second sheet 519, the hole 521, and the second frame 540 are identical to the first sheet 509, the hole 511, and the first frame 530, respectively. The third frame 550 and the aerosol forming substrate 560 can then be closed by welding the second frame 540 to the first frame 530, which can be achieved by ultrasonic welding.

[0146] Reference Figure 26 The lateral extensions of the second sheet 519 and the first sheet 509 are cut (e.g., die-cut, laser-cut), thereby allowing the second heater 520 and the first heater 510 (e.g., Figure 17 The capsules are separated from the capsule 500 as a whole. Multiple capsules can be produced relatively stably and efficiently using the sheet / mesh method discussed herein, for example, in an automated manner. Although the sheet / mesh method has been discussed above in conjunction with a heater, it should be understood that this method can also be applied to aerosol forming substrates (e.g., aerosol forming substrate 760).

[0147] Figure 27 This is a schematic diagram of an aerosol generating apparatus according to an exemplary embodiment. (Refer to...) Figure 27 The aerosol generating device 1000 (e.g., an unburned heated aerosol generating device) may include a mouthpiece 1015 and a device body 1025. A power supply 1035 and control circuitry 1045 may be housed within the device body 1025 of the aerosol generating device 1000. The aerosol generating device 1000 is configured to receive a capsule 800, which may be as described in relation to any embodiment herein. The aerosol generating device 1000 may also include a first electrode 1055a, a second electrode 1055b, a third electrode 1055c, and a fourth electrode 1055d, said electrodes configured to make electrical contact with the capsule 800. In one exemplary embodiment, if the capsule 800 has a similar... Figure 1Given the structure of the capsule 100, the first electrode 1055a and the third electrode 1055c can electrically contact the first heater 110, while the second electrode 1055b and the fourth electrode 1055d can electrically contact the second heater 120. However, in a non-limiting embodiment involving a capsule with only one heater, it should be understood that the first electrode 1055a and the third electrode 1055c (or the second electrode 1055b and the fourth electrode 1055d) can be omitted.

[0148] When the capsule 800 is inserted into the aerosol generating device 1000, the control circuit 1045 can instruct the power supply 1035 to provide current to the first electrode 1055a, the second electrode 1055b, the third electrode 1055c, and / or the fourth electrode 1055d. The current supply from the power supply 1035 can be in response to manual operation (e.g., button activation) or automatic operation (e.g., jet activation). As a result of the current, the capsule 800 can be heated to generate an aerosol.

[0149] Other details of the capsule 800 and the aerosol generating device 1000, including the mouthpiece 1015, the device body 1025, the power supply 1035, the control circuit 1045, the first electrode 1055a, the second electrode 1055b, the third electrode 1055c, and the fourth electrode 1055d, can be found in U.S. Patent Application No. 15 / 845,501, Atty.Dkt.No.24000DM-000012-US, filed December 18, 2017, entitled "VAPORIZING DEVICES AND METHODS FOR DELIVERING ACOMPOUND USING THE SAME", the entire disclosure of which is incorporated herein by reference. The capsules, aerosol-forming substrates, and related aspects discussed herein are also described in more detail in U.S. Application No. 16 / 252,951, filed January 21, 2019, entitled "CAPSULE, HEAT-NOT-BURN (HNB) AEROSOL-GENERATINGDEVICES, AND METHODS OF GENERATING AN AEROSOL," the disclosure of which is incorporated herein by reference in its entirety.

[0150] Figure 28 This is a cross-sectional view of another aerosol generating apparatus according to an exemplary embodiment. (Refer to...) Figure 28 The aerosol generating device 2000 (e.g., an unheated aerosol generating device) may include, among other things, a mouthpiece 2015 and a device body 2025. It should be understood that, with Figure 27 The features related to the aerosol generating device 1000 also apply to this section, and will not be repeated for the sake of brevity. For example... Figure 28 As shown, a sensor 2075 may be included to measure the temperature of a capsule within the aerosol generating device 2000. For example, sensor 2075 may be an infrared (IR) sensor configured for non-contact temperature sensing of the capsule. Sensor 2075 may be positioned downstream and above the capsule within the device body 2025. Furthermore, sensor 2075 may be offset from the aerosol path and at an angle relative to the longitudinal axis of the aerosol generating device 2000. In one exemplary embodiment, the longitudinal axis may be orthogonal to a plane corresponding to the capsule surface, and the angle relative to the longitudinal axis may be 8-20 degrees (e.g., 13-15 degrees). Therefore, the accumulation and deposition of generated aerosols can be reduced or prevented, thereby improving the performance and lifespan of sensor 2075. Further details of the capsule and aerosol generating device, including the sensor and electrode movement mechanism, can also be found in U.S. Application 15 / 559,308, entitled "VAPORIZER FOR VAPORIZING AN ACTIVE INGREDIENT," filed September 18, 2017, Atty.Dkt.No.24000DM-000003-US-NP, the disclosure of which is incorporated herein by reference in its entirety.

[0151] Figure 29 It is a plan view of an arrangement according to an exemplary embodiment, the arrangement including a capsule of an aerosol generating device joined by electrodes and seals. Figure 30 yes Figure 29 A perspective view of the layout. Figure 31 yes Figure 29 The side cross-sectional view of the arrangement. (Refer to...) Figures 29-31 The capsule 900 within the aerosol generating device can be engaged by a first seal 1165a and a second seal 1165b. The first seal 1165a can engage with the side of the capsule 900 corresponding to the first heater, while the second seal 1165b can engage with the side of the capsule 900 corresponding to the second heater (or vice versa). When engaged, the first seal 1165a and the second seal 1165b can surround the aerosol forming substrate disposed therein, thus enclosing the cavity.

[0152] The first electrode 1155a, the second electrode 1155b, the third electrode 1155c, and the fourth electrode 1155d are configured to make electrical contact with the capsule 900. In one exemplary embodiment, if the capsule 900 has a similar Figure 1Given the structure of the capsule 100, the first electrode 1155a and the third electrode 1155c can electrically contact the first heater 110, while the second electrode 1155b and the fourth electrode 1155d can electrically contact the second heater 120. However, in a non-limiting embodiment involving a capsule with only one heater, it should be understood that the first electrode 1155a and the third electrode 1155c (or the second electrode 1155b and the fourth electrode 1155d) can be omitted.

[0153] When engaged with the heater, the first electrode 1155a and the third electrode 1155c are located within the area defined by the first seal 1165a, while the second electrode 1155b and the fourth electrode 1155d are located within the area defined by the second seal 1165b. The first electrode 1155a and the third electrode 1155c may also be adjacent to opposite sides of the first seal 1165a, thus pressing the first heater against the underlying first frame. Similarly, the second electrode 1155b and the fourth electrode 1155d may be adjacent to opposite sides of the second seal 1165b, thus pressing the second heater against the underlying second frame. In an exemplary embodiment involving a third frame, the heater may be pressed against the underlying third frame via the electrodes.

[0154] The first electrode 1155a, second electrode 1155b, third electrode 1155c, and fourth electrode 1155d can be in the form of blades. Furthermore, to reduce contact resistance, the first electrode 1155a, second electrode 1155b, third electrode 1155c, and fourth electrode 1155d can be formed of steel and coated with titanium nitride. In one exemplary embodiment, the blades can have smooth edges. Alternatively, the blades can be rough to enhance electrical contact when the heater has an uneven surface (e.g., a heater in the form of a mesh).

[0155] The first electrode 1155a, second electrode 1155b, third electrode 1155c, and fourth electrode 1155d may be spring-loaded so that they are defaulted to an closed / engaged position. For example, the first electrode 1155a may be biased toward the second electrode 1155b, and the third electrode 1155c may be biased toward the fourth electrode 1155d. The drive of the first electrode 1155a, second electrode 1155b, third electrode 1155c, and fourth electrode 1155d to the open / disengaged position can be performed manually. In an exemplary embodiment, a lever may be connected to the first electrode 1155a and the third electrode 1155c, such that the first electrode 1155a and the third electrode 1155c are movable and configured to move together, while the second electrode 1155b and the fourth electrode 1155d are stationary. Conversely, a lever can be connected to the second electrode 1155b and the fourth electrode 1155d, thereby moving the second electrode 1155b and the fourth electrode 1155d and configuring them to move together, while the first electrode 1155a and the third electrode 1155c remain stationary. Alternatively, a first lever can be connected to the first electrode 1155a and the third electrode 1155c, and a second lever can be connected to the second electrode 1155b and the fourth electrode 1155d, thereby making all four electrodes movable and configured to move together. In this case, the first and second levers can be arranged in a cross shape to allow for a scissor-like movement upon actuation, but the exemplary embodiment is not limited to this.

[0156] To achieve the open / disengaged position (e.g., for insertion of the capsule 900), a lever can be pressed to separate the first electrode 1155a and the third electrode 1155c from the second electrode 1155b and the fourth electrode 1155d, respectively. Upon releasing the lever, the first electrode 1155a, the second electrode 1155b, the third electrode 1155c, and the fourth electrode 1155d can be configured to return to the default closed position by virtue of their spring-loaded arrangement (e.g., for engagement with the capsule 900 inserted into the aerosol generating device). However, it should be understood that in some cases, the spring-loaded arrangement may be omitted for the first electrode 1155a, the second electrode 1155b, the third electrode 1155c, and / or the fourth electrode 1155d. In this case, manually moving the lever in the opposite direction will achieve the desired movement of the first electrode 1155a, the second electrode 1155b, the third electrode 1155c, and / or the fourth electrode 1155d. In addition, the lever can be configured to require a conscious level of manual force to move, so that the lever can remain in its position until further movement is required.

[0157] In another exemplary embodiment, the aforementioned open and closed positions of the first electrode 1155a, second electrode 1155b, third electrode 1155c, and fourth electrode 1155d can be achieved using a rack and pinion arrangement. The rack and pinion arrangement includes a circular gear (pinion) that engages with a linear gear (rack) to convert the rotational motion of the circular gear into the linear motion of the linear gear (and vice versa). For example, the linear gear can be connected to the first electrode 1155a and the third electrode 1155c such that the first electrode 1155a and the third electrode 1155c are movable and configured to move together as the respective circular gears rotate, while the second electrode 1155b and the fourth electrode 1155d are stationary. Conversely, a linear gear can be connected to the second electrode 1155b and the fourth electrode 1155d, thereby making the second electrode 1155b and the fourth electrode 1155d movable and configured to move together as the respective circular gears rotate, while the first electrode 1155a and the third electrode 1155c remain stationary. Alternatively, the first linear gear can be connected to the first electrode 1155a and the third electrode 1155c, and the second linear gear can be connected to the second electrode 1155b and the fourth electrode 1155d, so that all four electrodes are movable and configured to move together as the respective gears or gear assemblies rotate. In this case, an intermediate circular gear can be provided for one of the first or second linear gears, so that the first and second linear gears move in opposite directions (e.g., in parallel) as the main circular gear rotates. It is worth noting that the main circular gear can engage directly with the first linear gear while engaging indirectly with the second linear gear (or vice versa) through the intermediate circular gear.

[0158] To achieve the open / disengaged position (e.g., for insertion of the capsule 900), the circular gear can be rotated to move the linear gears away from each other, thereby separating the first electrode 1155a and the third electrode 1155c from the second electrode 1155b and the fourth electrode 1155d, respectively. Upon releasing the circular gear, the first electrode 1155a, the second electrode 1155b, the third electrode 1155c, and the fourth electrode 1155d can be configured to return to the default closed position by virtue of their spring-loaded arrangement (e.g., for engagement with the capsule 900 inserted into the aerosol generating device). However, it should be understood that in some cases, the spring-loaded arrangement can be omitted for the first electrode 1155a, the second electrode 1155b, the third electrode 1155c, and / or the fourth electrode 1155d. In this case, manually rotating the circular gear in the opposite direction will achieve the desired linear movement of the first electrode 1155a, the second electrode 1155b, the third electrode 1155c, and / or the fourth electrode 1155d. Furthermore, the circular gear can be configured to move at a conscious level requiring manually guided rotational force, so that the circular gear holds its position until further movement is needed.

[0159] The first seal 1165a and the second seal 1165b are also configured to switch between an open / disengaged position (e.g., for insertion of the bladder 900) and a closed / engaged position (e.g., clamping and defining an air passage through the inserted bladder 900). Although not illustrated, the first seal 1165a and the second seal 1165b may be mounted on (or otherwise incorporated into) a clamping structure configured to perform open and close movements. Movement of the clamping structure may be associated with movement of the first electrode 1155a, the second electrode 1155b, the third electrode 1155c, and the fourth electrode 1155d. For example, movement of the clamping structure (and the first seal 1165a and / or the second seal 1165b) may involve the lever and / or rack and pinion arrangement described above. Furthermore, instead of manual actuation (e.g., manual actuation of the electrodes and / or seals), automatic actuation may be implemented, whereby pressing a button (or other electronic control) will achieve the desired open or close movement.

[0160] Figure 32 This is a front view of the electrodes of an aerosol generating apparatus according to an exemplary embodiment. (Refer to...) Figure 32 Electrode 1255 may include a base portion 1256, a first elastic portion 1257a, a second elastic portion 1257b, and a blade portion 1258. Each of the first elastic portion 1257a and the second elastic portion 1257b may be coil-shaped (e.g., flexible) to accommodate inconsistencies in the capsule to enhance electrical contact with its heater. Blade portion 1258 may have flat edges. Electrodes similar to electrode 1255 are shown (at least partially) in... Figure 28 In the aerosol generating device 2000.

[0161] Figure 33 This is a front view of another electrode of an aerosol generating apparatus according to an exemplary embodiment. (Refer to...) Figure 33 Electrode 1355 may include a base portion 1356, an elastic portion 1357, and a blade portion 1358. The elastic portion 1357 may be coil-shaped, designed to accommodate inconsistencies in the capsule to enhance electrical contact with its heater. The blade portion 1358 may be serrated. While several examples of electrodes are illustrated in the figures and discussed herein, it should be understood that other variations are possible. For example, Figure 33 The electrode 1355 can have Figure 32 The first elastic portion 1257a and the second elastic portion 1257b. In another example, Figure 33 The electrode 1355 can have Figure 32 The blade part 1258.

[0162] Figure 34 This is a diagram showing the connection lines and connection points for the electrode-to-heater connection according to an exemplary embodiment. (Refer to...) Figure 34 The electrode can be engaged with the heater 1410, as shown by connecting line 1414. Therefore, in this case, connecting line 1414 represents the position where the electrode is engaged with the heater 1410. Furthermore, when the heater is in the form of a mesh, as... Figure 34 As shown, the mesh-like conductors can be at an angle relative to the connecting line 1414. For example, the mesh-like conductors can be at an angle of 35-55 degrees (e.g., 45 degrees) relative to the connecting line 1414. The connecting line 1414 can also be substantially parallel to one side of the capsule (e.g., Figure 29 Therefore, the number of connection points 1416 with the electrodes can be increased, thereby improving electrical contact and heating.

[0163] While some exemplary embodiments have been disclosed herein, it should be understood that other modifications are possible. Such modifications should not be considered as departing from the spirit and scope of this disclosure, and all such modifications that will be apparent to those skilled in the art are included within the scope of the following claims.
