Description

Technical Field

[0001] This application relates to the field of smoke generation technology, and in particular to an aerosol generation matrix segment and an aerosol generation product. Background Technology

[0002] Aerosol generating products generally produce aerosols by heating without combustion. Specifically, the aerosol generating product is equipped with an aerosol generating matrix section. The aerosol generating product is heated by heating elements in the aerosol generating device until the aerosol generating matrix section is heated to a level sufficient to emit fragrance, but the aerosol generating matrix section does not burn.

[0003] However, the aerosol generation matrix section in related technologies is prone to insufficient heating, resulting in low heating efficiency and a poor suction experience. Summary of the Invention

[0004] In view of this, the embodiments of this application aim to provide an aerosol generation matrix segment and an aerosol generation article that have a better suction experience and higher structural strength.

[0005] To achieve the above objectives, embodiments of this application provide an aerosol generation matrix segment, comprising:

[0006] An outer wall is constructed to enclose the accommodating space. The outer wall has a first length dimension along a first direction and a second length dimension along a second direction. The first direction is perpendicular to the second direction, and the first length dimension is smaller than the second length dimension.

[0007] An airway wall is disposed within the accommodating space, the airway wall dividing the accommodating space into multiple airflow channels, wherein the airway wall includes at least a first airway wall, the first airway wall being connected to the outer perimeter wall on opposite sides along the first direction.

[0008] In one embodiment, the outer wall has an air passage groove formed by a recess in the direction toward the receiving space on the side opposite to the receiving space.

[0009] In one embodiment, the outer perimeter wall includes two first wall bodies, which are located on opposite sides of the outer perimeter wall along the first direction, and at least one of the two first wall bodies is provided with the air passage groove.

[0010] In one embodiment, a portion of the first wall protrudes into the receiving space from the side opposite to the receiving space to the side closer to the receiving space, thereby forming the airway groove.

[0011] In one embodiment, the first airway wall is connected to the portion of the first wall body that protrudes into the receiving space.

[0012] In one embodiment, the maximum outer contour of the cross-section of the outer wall lies on the same virtual runway-shaped, virtual elliptical, or virtual rectangular contour line.

[0013] In one embodiment, the cross-sectional shape of the outer wall is racetrack-shaped, elliptical, or rectangular.

[0014] In one embodiment, the airway wall further includes a second airway wall extending between opposite sides of the peripheral wall along the second direction.

[0015] In one embodiment, the second airway wall is at least connected to the first airway wall. The first airway wall connected to the second airway wall includes a first segment having the airflow passage and two second segments located at opposite ends of the first segment along the first direction. The first segment protrudes from opposite sides of each of the second segments along the second direction and is connected to the second airway wall.

[0016] In one embodiment, the aerosol generating matrix segment includes a first region and two second regions respectively provided with the airflow channels. The two second regions are respectively located on opposite sides of the first region along the second direction, and the cross-sectional area of ​​the airflow channels in each of the second regions is larger than the cross-sectional area of ​​the airflow channels in the first region.

[0017] In one embodiment, the first length dimension does not exceed 4 mm; and / or,

[0018] The ratio of the second length dimension to the first length dimension is 2 to 5.

[0019] In one embodiment, at least one of the outer perimeter wall and the airway wall has a wall thickness of 0.1 mm to 5 mm; and / or,

[0020] The thickness of the outer wall is the same as the thickness of the airway wall; and / or,

[0021] The number of airflow channels ranges from 2 to 50.

[0022] This application also provides an aerosol generating article, characterized in that it comprises:

[0023] The aforementioned aerosol generation matrix segment;

[0024] A functional segment is disposed on one side of the aerosol generating matrix segment along a third direction, the third direction being perpendicular to the first direction and the second direction respectively;

[0025] An outer wrapping component that wraps around the outer periphery of the aerosol generating matrix section and the functional section.

[0026] In one embodiment, the functional section includes at least a cooling section for cooling the aerosol.

[0027] In one embodiment, the functional segment further includes a filtration segment, which is disposed on the side of the cooling segment away from the aerosol generating matrix segment along the third direction.

[0028] This application provides an aerosol generation matrix segment and an aerosol generation article. The aerosol generation matrix segment, by setting a first length dimension of its outer wall along a first direction smaller than its second length dimension along a second direction, allows for faster heat transfer in the first direction during heating. This enables rapid, efficient, and uniform heating of the aerosol generation matrix segment, improving its heating efficiency. The aerosol can also be released quickly and fully into the airflow channels of the aerosol generation matrix segment, thereby improving aerosol extraction efficiency and enhancing the suction experience. Since the second length dimension of the outer wall along the second direction is relatively large, the aerosol generation matrix segment is provided with at least a first airway wall, which connects to the opposite sides of the outer wall along the first direction. This effectively supports the portion of the outer wall along the second direction, minimizing deformation and resulting in higher structural strength. Therefore, the aerosol generation matrix segment of this application not only provides a better suction experience but also exhibits high structural strength. Attached Figure Description

[0046] In the description of the embodiments of this application, it should be noted that the terms "first direction," "second direction," etc., indicate the orientation or positional relationship based on the appendix. Figure 4 The indicated orientation or positional relationship, such as "third direction", is based on the attached... Figure 5 The orientations or positional relationships shown are for the convenience of describing the embodiments of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0047] This application provides an aerosol generation matrix segment 10. Please refer to [link / reference]. Figures 3 to 15 The aerosol generating matrix segment 10 includes an outer wall 11 and an airway wall 12.

[0048] The aerosol generation matrix section 10 is used to release aerosols for users to inhale or for use in medicine, beauty, etc. after being heated and atomized by a heating element set in the aerosol generation device.

[0049] There are various heating methods for heating elements. For example, heating methods include center heating and peripheral heating. Center heating refers to the heating element being inserted into the aerosol generating matrix section 10 to bake and heat the aerosol generating matrix section 10. Peripheral heating refers to the heating element being positioned around the aerosol generating matrix section 10 to bake and heat the aerosol generating matrix section 10.

[0050] These heating methods can specifically include resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, etc., without being specifically limited here.

[0051] The specific structure of the aerosol generating matrix segment 10 is not limited here. Exemplarily, the aerosol generating matrix segment 10 can be made of the atomizing medium itself, such as a smoky flavoring medium. In other embodiments, the aerosol generating matrix segment 10 may also include a matrix and an atomizing medium disposed on the matrix. The matrix may be, for example, high-temperature resistant carbon fiber. In this way, by providing a matrix, the strength of the aerosol generating matrix segment 10 can be improved, and it can withstand a certain degree of high temperature without producing odor.

[0052] The specific composition of the aerosol generating matrix segment 10 is not limited here. For example, in one embodiment, the aerosol generating matrix segment 10 may include plant components, auxiliary components, smoke generating components, adhesive components, etc.

[0053] In one embodiment, the plant-based ingredients are one or more combinations of raw tobacco leaves, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants, which are powdered after being crushed. The plant-based ingredients are the core source of the product's aroma. Endogenous substances in the plant-based ingredients, such as nicotine, enter the bloodstream through atomization, promoting the pituitary gland to produce dopamine, thereby generating a sense of physiological satisfaction.

[0054] In one embodiment, the auxiliary component can be one or more combinations of inorganic fillers, lubricants, and emulsifiers. The inorganic fillers include one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. The inorganic fillers provide skeletal support for the plant components, and their micropores increase the porosity of the wall material after molding, thereby improving the aerosol release rate.

[0055] Lubricants include one or more of the following: candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. Lubricants can increase the flowability of particles, reduce friction between particles, result in a more uniform overall particle density, and also reduce the pressure required for mold forming, thus reducing mold wear.

[0056] Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers can, to some extent, slow down the loss of flavor substances during storage, increase the stability of flavor substances, and improve the sensory quality of the product. Emulsifiers (also known as surfactants) can reduce the interfacial tension between water-soluble and water-insoluble components in a mixture, and form a more robust film on the surface of microdroplets or an electric double layer on the surface of microdroplets due to the charge given by the emulsifier, preventing microdroplets from agglomerating and maintaining a homogeneous emulsion. Homogenizing two immiscible components through emulsification can improve the consistency of product quality.

[0057] The function of the smoke-generating agent is to produce a large amount of vapor upon heating, thereby increasing the amount of smoke in the smoke-generating product. In one embodiment, the smoke-generating agent may include, for example, one or more combinations of: a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, triethylene glycol, 1,3-butanediol, and glycerol); an ester of a polyhydric alcohol (such as glyceryl monoacetate, glyceryl diacetate, or glyceryl triacetate); a monocarboxylic acid; a polycarboxylic acid (such as lauric acid, myristic acid) or an aliphatic ester of a polycarboxylic acid (such as dimethyl dodecanoate, dimethyl tetradecanoate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl lauryl acetate, triacetin, meso-erythritol, a mixture of diacetins, diethyl caprylate, triethyl citrate, methyl benzoate, phenylacetic acid methyl ester, ethyl vanillate, glyceryl tributate, and lauryl acetate).

[0058] In one embodiment, the adhesive component is a natural plant extract, a non-ionic modified viscous polysaccharide, including one or more combinations of tamarind polysaccharide, pullulan polysaccharide, seaweed polysaccharide, locust bean gum, guar gum, and xyloglucan. The adhesive achieves close contact with the product component materials through wetting at the interface, generating intermolecular attraction, thereby binding the powder, liquid, or other components. Furthermore, the use of a natural plant extract and a non-ionic adhesive avoids the release of harmful substances such as methanol, formaldehyde, and acrolein associated with colloidal modification, thus improving the safety of the product.

[0059] For example, the aerosol generating matrix segment 10 can be a particulate aggregate, which is a reconstituted tobacco medium, such as a reconstituted tobacco medium containing smoke-generating agents, tobacco, and other components. The particulate aggregate aerosol generating matrix segment 10 remains an integral medium after being heated and inhaled or after heating is stopped, and is not prone to disintegration and falling off. This solves the problems of thin sheet-like, filamentous, or loose particulate aerosol generating matrices in the prior art, such as sheet detachment, filamentous components falling off, and difficulty in cleaning.

[0060] The aerosol generation matrix segment 10 can be prepared by any of the following processes: extrusion, injection molding, die casting, 3D printing, and cold heading. These processes can ensure that the cross-section of the aerosol generation matrix segment 10 is consistent, thereby ensuring that the aerosol generation matrix segment 10 is heated more uniformly and that heat and mass transfer are more consistent, which in turn can improve the consistency of aerosol release.

[0061] Please continue reading. Figures 3 to 15 The outer wall 11 encloses the receiving space. Please refer to [link / reference]. Figure 4 The outer wall 11 has a first length dimension L1 along a first direction and a second length dimension L2 along a second direction. The first direction is perpendicular to the second direction, and the first length dimension L1 is smaller than the second length dimension L2. That is, the cross-section of the outer wall 11 (here and below, the cross-section refers to the cross-section parallel to the first and second directions) has different length dimensions in the two perpendicular directions (i.e., the first direction and the second direction), which means that the outer wall 11 is narrower on the opposite sides along the first direction and wider on the opposite sides along the second direction.

[0062] The wall thickness D1 of the outer wall 11 can be designed as needed. However, when the wall thickness D1 of the outer wall 11 is less than 0.1 mm, the manufacturing difficulty of the aerosol generating matrix section 10 is relatively high, which is not conducive to production. When the wall thickness D1 of the outer wall 11 is greater than 5 mm, the aerosol generating matrix section 10 may reduce its utilization efficiency due to insufficient heating during the heating process. Therefore, more preferably, the wall thickness D1 of the outer wall 11 can be 0.1 mm to 5 mm (including the endpoint value). For example, the wall thickness D1 of the outer wall 11 can be 0.1 mm, 0.2 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 5 mm, etc. More preferably, the wall thickness D1 of the outer wall 11 can be 0.2 mm to 3 mm (including the endpoint value).

[0063] The outer wall 11 is used to form the outer contour of the aerosol generation matrix segment 10. The first length dimension L1 and the first length dimension L2 of the outer wall 11 are actually the length dimensions of the aerosol generation matrix segment 10 along the first direction and the second direction.

[0064] The purpose of setting the first length dimension L1 of the outer wall 11 to be smaller than the first length dimension L2 is to enable heat to be transferred more quickly in the first direction during the heating process of the aerosol generation matrix section 10, thereby facilitating the full heating of the aerosol generation matrix section 10.

[0065] The specific value of the first length dimension L1 can be designed as needed. However, in order to facilitate the rapid transfer of heat in the first direction, it is preferable that the first length dimension L1 can not exceed 4mm. For example, the first length dimension L1 can be 1mm, 2mm, 3mm, 4mm, etc.

[0066] The ratio of the first length dimension L2 to the first length dimension L1 can be designed as needed. Preferably, the ratio of the first length dimension L2 to the first length dimension L1 can be 2 to 5 (including the endpoint values). For example, the ratio of the first length dimension L2 to the first length dimension L1 can be 2, 2.5, 3, 4, 5, etc.

[0067] Please see Figures 3 to 15 The airway wall 12 is disposed within the accommodating space, and the airway wall 12 divides the accommodating space into multiple airflow channels 10a. The airway wall 12 includes at least a first airway wall 12a, which is connected to the outer wall 11 on opposite sides along a first direction.

[0068] The airway wall 12 mainly serves a supporting function, essentially acting as the framework for the aerosol generation matrix segment 10.

[0069] The wall thickness D2 of the airway wall 12 can be designed as needed. However, when the wall thickness D2 of the airway wall 12 is less than 0.1 mm, the manufacturing difficulty of the aerosol generating matrix section 10 is relatively high, which is not conducive to production. When the wall thickness D2 of the airway wall 12 is greater than 5 mm, the aerosol generating matrix section 10 may reduce its utilization efficiency due to insufficient heating during the heating process. Therefore, more preferably, the wall thickness D2 of the airway wall 12 can be 0.1 mm to 5 mm (including the endpoint value). For example, the wall thickness D2 of the airway wall 12 can be 0.1 mm, 0.2 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 5 mm, etc. More preferably, the wall thickness D2 of the airway wall 12 can be 0.2 mm to 3 mm (including the endpoint value).

[0070] The wall thickness D2 of the airway wall 12 can be the same as or different from the wall thickness D1 of the outer wall 11. However, in order to ensure that the heat transfer and mass transfer of the aerosol generation matrix section 10 are more consistent during the heating process, it is preferable that the wall thickness D2 of the airway wall 12 is the same as the wall thickness D1 of the outer wall 11.

[0071] The number of airway walls 12 can be one or more, but regardless of whether the number of airway walls 12 is one or more, the airway walls 12 include at least the first airway wall 12a.

[0072] It should be noted that the first airway wall 12a is actually just one type of airway wall 12 disposed within the accommodating space; the difference in name is used for ease of description. Specifically, the first airway wall 12a refers to the airway wall 12 that connects to the outer perimeter wall 11 on opposite sides along the second direction.

[0073] If there is only one airway wall 12, then that airway wall 12 is the first airway wall 12a. If there are multiple airway walls 12, then all of them can be the first airway wall 12a, or a portion of the multiple airway walls 12 can be the first airway wall 12a.

[0074] For example, Figures 1 to 6 All the airway walls 12 shown are first airway walls 12a, while Figures 7 to 15 Of all the airway walls 12 shown, only a portion of the airway walls 12 are the first airway wall 12a.

[0075] The shape of the first airway wall 12a is not limited, as long as it can be connected to the opposite sides of the outer wall 11 along the second direction.

[0076] For example, please refer to Figure 3 The first airway wall 12a can be a flat plate, that is, the cross-sectional shape of the first airway wall 12a is a straight line. Figure 3The first airway wall 12a shown is parallel to the first direction. In other embodiments, the first airway wall 12a may also be inclined relative to the first direction.

[0077] For example, the first airway wall 12a may also be curved, for example, Figure 14 Multiple first airway walls 12a are provided, wherein the two outermost first airway walls 12a along the second direction are curved.

[0078] For example, please refer to Figure 12 The first airway wall 12a may include a first segment 12a1 and two second segments 12a2, which are located at opposite ends of the first segment 12a1 along a first direction. The first segment 12a1 protrudes from opposite sides of each of the second segments 12a2 along the second direction, and the first segment 12a1 has an airflow channel 10a. That is, the first airway wall 12a itself can also divide the airflow channel 10a, for example, Figure 12 The first segment 12a1 shown has four edges, and the square hole formed by the four edges is the airflow channel 10a separated by the first segment 12a1.

[0079] In other embodiments, the first airway wall 12a may also be a combination of other shapes and / or structures.

[0080] When there are multiple first airway walls 12a, each first airway wall 12a may have the same shape, or some of the first airway walls 12a may have different shapes.

[0081] The airflow channel 10a is used to gather aerosols generated by heating the matrix section 10 and to make the aerosols flow along the airflow channel 10a, thereby increasing the flow rate of the aerosols and thus improving the extraction efficiency of the aerosols.

[0082] It is understandable that the space within each airflow channel 10a is actually part of the containment space enclosed by the outer wall 11.

[0083] The number of airflow channels 10a can be designed as needed. However, considering the upper limit of the weight of the aerosol generation matrix section 10, the structural strength, and the amount of aerosol generated, it is preferable that the number of airflow channels 10a can be 2 to 50 (including the endpoint values). For example, the number of airflow channels 10a can be 2, 5, 10, 20, 30, 50, etc.

[0084] To improve the consistency of aerosol release, preferably, the airflow channels 10a can be axially symmetrically distributed.

[0085] This application also provides an aerosol-generating article; please refer to [link / reference]. Figure 1 and Figure 2 The aerosol generating article includes a functional segment 20, an outer wrapping component, and an aerosol generating matrix segment 10 provided in any embodiment of this application.

[0086] Functional segment 20 is located on one side of aerosol generation matrix segment 10 along a third direction, which is perpendicular to the first direction and the second direction respectively.

[0087] Function segment 20 is mainly used to provide certain auxiliary functions during the user's suction process.

[0088] For example, please refer to Figure 2 Functional section 20 may include at least a cooling section 21 for cooling the aerosol. That is, the cooling section 21 is used to cool the aerosol before it enters the user's mouth, so as to reduce the inlet temperature of the aerosol and improve the "burning mouth" phenomenon when the user inhales the aerosol.

[0089] The materials of the cooling section 21 include, but are not limited to, one or more combinations of PE (Polyethylene), PLA (Polylactic Acid), PBAT (Butylene adipate-co-terephthalate), PP (Polypropylene), cellulose acetate, and cellulose acrylic.

[0090] Cooling section 21 can be set Figure 2 The cooling channel 21a shown is used for cooling aerosols. The cooling section 21 may also be without a cooling channel 21a. For example, the cooling section 21 may adopt a microporous structure that allows airflow to pass through.

[0091] For example, please refer to Figure 2 The functional section 20 may also include a filter section 22, which is located on the side of the cooling section 21 away from the aerosol generation matrix section 10 in a third direction.

[0092] The filter section 22 is designed to come into contact with the user's mouth during inhalation to filter the aerosol.

[0093] The materials of filter section 22 include, but are not limited to, one or more combinations of PE, PLA, PBAT, PP, cellulose acetate, and propylene fiber.

[0094] For example, functional segment 20 may also include a support segment, which is mainly used to provide support for aerosol generation matrix segment 10 to improve the structural strength of aerosol generation matrix segment 10, especially the structural strength at high temperatures.

[0095] For example, the support segment can have good structural strength at a high temperature of at least 200°C.

[0096] In some scenarios, the support section can also provide a certain amount of suction resistance.

[0097] The materials for the support section include, but are not limited to, cellulose acetate, PET (polyethylene terephthalate), plant fibers, and non-plant fibers.

[0098] The support section can be located between the cooling section 21 and the aerosol generation matrix section 10, or it can be located on the side of the cooling section 21 away from the aerosol generation matrix section 10 in a third direction.

[0099] The outer casing is wrapped around the outer periphery of the aerosol generation matrix section 10 and the functional section 20.

[0100] The material of the outer packaging is not limited, for example, including but not limited to one or more combinations of materials such as fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE, PBAT, etc.

[0101] For example, please refer to Figure 1 and Figure 2 The outer packaging may include a first packaging 31 and a second packaging 32. The first packaging 31 encloses a portion of the aerosol generating matrix segment 10 and the functional segment 20, and the second packaging 32 encloses the functional segment 20 and a portion of the first packaging 31.

[0102] In other embodiments, the first wrapping element 31 and the second wrapping element 32 may not be provided. For example, an outer wrapping element may simultaneously wrap the aerosol generating matrix segment 10 and the functional segment 20.

[0103] In related technologies, the aerosol generating matrix segment is generally cylindrical. For peripheral heating, the heat transfer path at the center of the cylindrical aerosol generating matrix segment is relatively long, and the part near the center of the aerosol generating matrix segment is prone to insufficient heating. On the other hand, for central heating, there may be overheating in the center and insufficient heating in the periphery. Therefore, the heating efficiency of the cylindrical aerosol generating matrix segment is relatively low, and the suction experience is relatively poor.

[0104] In this embodiment, the aerosol generating matrix segment 10, by setting the first length dimension L1 of the outer wall 11 along the first direction to be smaller than the first length dimension L2 along the second direction, allows for faster heat transfer in the first direction during heating. This enables the aerosol generating matrix segment 10 to be heated quickly, efficiently, and uniformly, improving its heating efficiency. The aerosol can also be released quickly and fully into the airflow channel 10a of the aerosol generating matrix segment 10, thereby improving aerosol extraction efficiency and enhancing the suction experience. Since the first length dimension L2 of the outer wall 11 along the second direction is relatively large, the aerosol generating matrix segment 10 is provided with at least a first airway wall 12a, which connects to the opposite sides of the outer wall 11 along the first direction. This effectively supports the portion of the outer wall 11 along the second direction, minimizing deformation and ensuring high structural strength for the aerosol generating matrix segment 10. Therefore, the aerosol generating matrix segment 10 of this application embodiment not only provides a better suction experience, but also has high structural strength.

[0105] In addition, the aerosol generating matrix segment 10 of this application embodiment is not only more suitable for the suction method of immediate extraction and stopping, but also more suitable for heating methods. For example, in addition to the conventional circumferential heating method and center heating method, it can also be suitable for single-sided (such as bottom, one side) heating method or double-sided heating method.

[0106] In one embodiment, please refer to Figures 7 to 15 The airway wall 12 may include a second airway wall 12b, which extends between opposite sides of the outer wall 11 along a second direction.

[0107] The second airway wall 12b is also a type of airway wall 12; the difference in name is simply for ease of description.

[0108] Specifically, the second airway wall 12b refers to the airway wall 12 that extends between the opposite sides of the outer wall 11 along the second direction and is not connected to the opposite sides of the outer wall 11 along the first direction.

[0109] The number of second airway walls 12b can be one or more.

[0110] The second airway wall 12b can be connected to at least the first airway wall 12a, for example, see [link to relevant documentation]. Figures 6 to 15The outer wall 11 includes two first wall bodies 112, which are located on opposite sides of the outer wall 11 along the second direction. When the number of first airway walls 12a is greater than one, the second airway wall 12b can be connected to the two adjacent first airway walls 12a, or to the first wall body 112 and the first airway wall 12a closest to the first wall body 112. When the number of first airway walls 12a is one, the second airway wall 12b can be connected to both the first wall body 112 and the first airway wall 12a.

[0111] Please continue reading. Figure 12 For a first airway wall 12a having a first segment 12a1 and two second segments 12a2, a second airway wall 12b can be connected to the first segment 12a1. Since the first segment 12a1 protrudes from the opposite sides of each of the second segments 12a2 along the second direction, that is, the thickness of the first segment 12a1 is greater than the thickness of the second segment 12a2, the second airway wall 12b can be connected to the first segment 12a1, which can improve the structural strength of the aerosol generation matrix segment 10.

[0112] In other embodiments, the second airway wall 12b may also be connected to other airway walls 12 besides the first airway wall 12a.

[0113] Setting up a second airway wall 12b can not only further improve the structural strength of the aerosol generation matrix section 10, but also increase the number of airway walls 12 and the number of airflow channels 10a, thereby increasing the amount of aerosol released and extracted, and bringing users a better suction experience.

[0114] In one embodiment, please refer to Figure 9 and Figure 10 An air passage groove 10b, formed by a recess in the direction of approaching the containment space, can be provided on the side of the outer wall 11 that is away from the containment space.

[0115] The number of airway slots 10b can be one or more.

[0116] The shape of the cross-section of the airway groove 10b is not limited. For example, the shape of the cross-section of the airway groove 10b can be... Figures 9 to 13 The triangle shown can also be Figure 14 and Figure 15 The rectangle shown can also be a semicircle, a semi-ellipse, a polygon other than a triangle, an irregular shape, etc.

[0117] When there are multiple airway grooves 10b, each airway groove 10b can adopt the same shape, or some airway grooves 10b can adopt different shapes.

[0118] The airway groove 10b can also collect aerosols, improving aerosol extraction efficiency. In addition, for the peripheral heating method, since the outer wall 11 is heated by the heating element first, the aerosols released by the outer wall 11 can be extracted more quickly through the airway groove 10b, thereby increasing the amount of smoke in the first three puffs and thus improving the consistency of the puff.

[0119] Please continue reading. Figures 9 to 15 The outer wall 11 includes two first wall bodies 111, which are located on opposite sides of the outer wall 11 along the first direction. Since heat can be transferred relatively quickly in the first direction during the heating process of the aerosol generation matrix section 10, it is preferable that the air channel groove 10b can be disposed on the first wall body 111.

[0120] Figures 9 to 15 Both first walls 111 are provided with airway grooves 10b. In some other embodiments, airway grooves 10b may be provided in one of the first walls 111, while airway grooves 10b may not be provided in the other first wall 111.

[0121] Please see Figures 9 to 15 A portion of the first wall 111 can protrude into the receiving space from the side opposite to the receiving space to the side closest to the receiving space, thereby forming an air passage groove 10b. In other words, the portion of the first wall 111 with the air passage groove 10b can be bent inwards into the receiving space as a whole. This arrangement allows the wall thickness of the first wall 111 to remain approximately uniform, without affecting the structural strength of the first wall 111 due to localized thinning of the portion with the air passage groove 10b.

[0122] Further, please refer to Figures 9 to 15 The first airway wall 12a can be connected to the portion of the first wall 111 that protrudes into the receiving space. That is, the first airway wall 12a can be located on the side of the first wall 111 opposite to the airway groove 10b. The first airway wall 12a can support and strengthen the portion of the first wall 111 that protrudes into the receiving space, thereby improving the overall structural strength of the aerosol generation matrix section 10.

[0123] In other embodiments, only a portion of the first wall 111 on the side opposite to the receiving space may be recessed to form the airway groove 10b. In other words, the side of the first wall 111 closest to the receiving space does not protrude into the receiving space.

[0124] In other embodiments, the airway groove 10b may not be provided on the first wall 111. For example, the airway groove 10b may be provided on at least one of the first walls 112.

[0125] In other embodiments, the first wall 111 and the first wall 112 may be respectively provided with air passage grooves 10b.

[0126] The maximum outer contour of the cross-section of the outer wall 11 can be located on the same virtual runway-shaped contour line, or on the same virtual rectangle contour line, or on the same virtual ellipse contour line.

[0127] A virtual runway shape is a virtual shape resembling a runway, a virtual rectangle is a virtual shape resembling a rectangle, and a virtual ellipse is a virtual shape resembling an ellipse.

[0128] In other words, the shape of the cross-section of the outer wall 11 can be as follows: Figures 10 to 15 The shape shown is roughly that of a runway, or it can be like... Figure 9 The shape shown is roughly rectangular, but it can also be roughly elliptical.

[0129] Since the shape and size of the cross-section of the functional section 20 are generally the same as or approximately the same as the shape and size of the cross-section of the aerosol generating matrix section 10, for the functional section 20 with the filter section 22, when the maximum outer contour of the cross-section of the outer wall 11 of the aerosol generating matrix section 10 is located on the same virtual runway shape, virtual ellipse or virtual rectangle contour line, the shape of the cross-section of the filter section 22 is generally the same as or similar to the shape of the virtual runway shape, virtual ellipse or virtual rectangle. And these shapes of filter sections 22 fit the human lips better and are more ergonomic. Therefore, with an aerosol generating device of a suitable shape, a better suction experience can be provided to the user.

[0130] It should be noted that the shape of the cross-section of the outer wall 11 is not limited to the above-mentioned shapes. In another embodiment, the cross-section of the outer wall 11 can also adopt any other shape, as long as the first length dimension L1 is less than the first length dimension L2.

[0131] In other embodiments, please refer to Figures 3 to 8 The outer wall 11 may also be without the airway groove 10b. For the outer wall 11 without the airway groove 10b, in order to make the filter section 22 fit the human lips better, the cross-sectional shape of the outer wall 11 can preferably be racetrack-shaped, elliptical or rectangular.

[0132] In one embodiment, please refer to Figure 11The aerosol generation matrix section 10 may include a first region and two second regions (dashed box Z1 represents the first region and dashed box Z2 represents the second region) respectively provided with airflow channels 10a. The two second regions are located on opposite sides of the first region along the second direction. The cross-sectional area of ​​the airflow channel 10a in each second region is larger than the cross-sectional area of ​​the airflow channel 10a in the first region. It should be noted that the cross-sectional area of ​​the airflow channel 10a refers to the area of ​​the cross-section of a single airflow channel 10a.

[0133] In other words, the airway wall 12 divides at least three airflow channels 10a in the second direction, and the cross-sectional area of ​​a single airflow channel 10a located approximately in the middle is smaller than the cross-sectional area of ​​the single airflow channels 10a on both sides. This design allows the airway wall 12 to be concentrated as much as possible in the middle of the aerosol generation matrix section 10, thereby enabling aerosols to be released more concentratedly from the middle of the aerosol generation matrix section 10. On the other hand, the larger cross-sectional area of ​​the single airflow channel 10a located in each second region can also reduce the number of airway walls 12 to a certain extent, so as to avoid excessive weight of the aerosol generation matrix section 10.
