[0033] In the description of the embodiments in this application, it should be noted that the terms "first direction" and "second direction" are based on the appended... Figure 1 and attached Figure 3 The orientation or positional relationship shown, "third direction" is based on the attached Figure 1 The orientation or positional relationship shown is merely for the convenience of describing the embodiments of this application and simplifying the description, and is 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.

[0034] This application provides an aerosol generating device; please refer to [link / reference]. Figure 1 and Figure 2 The aerosol generating device includes a housing assembly 10 and a heating assembly 20.

[0035] The housing assembly 10 includes a housing 11, which has a spaced-apart receiving cavity 11a and a product storage cavity 11b, an insertion interface 11c communicating with the receiving cavity 11a, and an opening 11d communicating with the product storage cavity 11b. The insertion interface 11c is located at one end of the housing 11 along a first direction, and the product storage cavity 11b is located on one side of the receiving cavity 11a along a second direction of the housing 11. The second direction is perpendicular to the first direction. The heating assembly 20 is disposed in the receiving cavity 11a.

[0036] The product storage cavity 11b is used to store aerosol-generated products, which are used in conjunction with the heating component 20.

[0037] Specifically, the aerosol generating product includes an aerosol generating matrix. The user can take the aerosol generating product out of the product storage cavity 11b from the opening 11d and insert the aerosol generating product into the receiving cavity 11a from the insertion port 11c. The heating component 20 in the receiving cavity 11a then heats and atomizes the aerosol generating matrix to generate aerosols for the user to inhale or for use in medicine, beauty, etc.

[0038] The heating component 20 can employ various heating methods. Exemplarily, these include center heating and peripheral heating. Center heating refers to the heating element being inserted into the aerosol-generating matrix to bake and heat it. Peripheral heating refers to the heating element being positioned around the aerosol-generating matrix to bake and heat it. These heating methods can specifically include resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, etc., and are not specifically limited here.

[0039] The specific structure of the aerosol generating matrix is ​​not limited here. For example, in one embodiment, the aerosol generating matrix may be made from the atomizing medium itself, such as a smoky flavoring medium. In other embodiments, the aerosol generating matrix 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 can be improved, and it can withstand a certain degree of high temperature without producing odor.

[0040] The specific composition of the aerosol generating matrix is ​​not limited here. For example, in one embodiment, the aerosol generating matrix may include plant components, auxiliary components, smoke-generating agent components, adhesive components, etc.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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).

[0046] 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.

[0047] For example, the aerosol generating matrix 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 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 sheet-like, filamentous, or loose particulate aerosol generating matrices in the prior art, such as sheet detachment, filamentous components falling off, particulate components falling off, and difficulty in cleaning.

[0048] The dimensions of the product storage cavity 11b can be adjusted according to design requirements, as long as it can accommodate the aerosol-generated products.

[0049] The number of aerosol-generated products that the product storage cavity 11b can hold is not limited. However, for the convenience of users, it is more preferable that the product storage cavity 11b can be designed to hold 10 to 20 aerosol-generated products (including the end value).

[0050] Please see Figure 1 The opening 11d can be located at the same end of the insertion interface 11c in the first direction, and the aerosol generated product can be placed into the product storage cavity 11b or taken out from the product storage cavity 11b along the first direction.

[0051] In other embodiments, the opening 11d may also be located on one of the opposite sides of the outer shell 11 along a third direction, which is perpendicular to the second direction and the first direction, respectively. That is, the aerosol-generated article may also be placed into or taken out of the article storage cavity 11b along the third direction.

[0052] By providing a product storage cavity 11b on the aerosol generating device, users can easily store the aerosol-generated product in the product storage cavity 11b, thus making it easier for users to carry both the aerosol-generated product and the aerosol generating device at the same time, thereby improving the user experience.

[0053] In one embodiment, please refer to Figure 1The housing assembly 10 can be provided with a cover 12, which is closable and can be placed over the opening 11d. That is, the cover 12 can be opened or closed. When the user puts the aerosol-generated product into the product storage cavity 11b through the opening 11d, the cover 12 is closed to seal the opening 11d. When the user needs to use the aerosol-generated product in the product storage cavity 11b, the cover 12 is opened again and the aerosol-generated product is taken out from the opening 11d. This can effectively prevent the aerosol-generated product stored in the product storage cavity 11b from falling out of the opening 11d.

[0054] In one embodiment, the cover 12 can be sealed to the outer shell 11. That is, after the cover 12 is closed, the product storage cavity 11b is in a relatively sealed state, which can prevent the product from getting damp due to aerosol generation in the product storage cavity 11b and thus affecting the user's experience.

[0055] For example, the cover 12 can achieve a sealed fit by making a sealing contact with the outer shell 11, and the cover 12 and the outer shell 11 can also achieve a sealed fit by providing a sealing ring.

[0056] In some other embodiments, the housing assembly 10 may not have a cover 12. In order to better prevent the aerosol-generating product stored in the product storage cavity 11b from falling out of the opening 11d, the product storage cavity 11b can fix the aerosol-generating product by interference fit with the aerosol-generating product. The product storage cavity 11b may also be provided with a snap-fit ​​structure that snaps into the aerosol-generating product, or a plug-in structure that plugs into the aerosol-generating product. The aerosol-generating product is fixed by snap-fit ​​structure or plug-in structure.

[0057] In one embodiment, the aerosol generating device may also be provided with a moisture-proof coating layer. The moisture-proof coating layer is provided on the inner wall of the product storage cavity 11b. That is, a moisture-proof coating layer can be formed by applying a moisture-proof coating to the inner wall of the product storage cavity 11b, which can also prevent the aerosol generating products stored in the product storage cavity 11b from getting damp and affecting the user's experience to a certain extent.

[0058] For example, the material of the moisture-proof coating layer can be one of food-grade moisture-proof materials such as aluminum foil, silicone, and polylactic acid.

[0059] In other embodiments, the material of the moisture-proof coating layer may be a combination of at least two of the above-mentioned materials, and the specific number of materials and the ratio between the various materials may be adjusted according to design requirements.

[0060] In one embodiment, please refer to Figure 1 and Figure 2The outer casing 11 may include a housing 111 and a partition 112. The housing 111 has an insertion interface 11c and an opening 11d. The partition 112 is disposed inside the housing 111 to separate the receiving cavity 11a and the product storage cavity 11b. That is, the receiving cavity 11a and the product storage cavity 11b can be formed by providing the partition 112 inside the housing 111.

[0061] The thickness of the partition 112 can be adjusted according to design requirements. However, when the thickness of the partition 112 is less than 1 mm, the structural strength of the partition 112 is poor and the heat insulation effect is also poor. When the thickness of the partition 112 is greater than 5 mm, the thickness of the partition 112 is too thick, which can easily lead to a larger overall size and weight of the aerosol generating device. Therefore, more preferably, the thickness of the partition 112 can be 1 mm to 5 mm (including the end value). For example, the thickness of the partition 112 can be 1 mm, 2 mm, 3 mm, 5 mm, etc.

[0062] The partition 112 can be made of a material with good heat insulation properties. For example, the material of the partition 112 can be one of the following heat-resistant materials: polyetheretherketone (PEEK), polyetherketone (PEK), polyetherketoneketone (PEKK), polyimide (PI), polyarylate (PAR), polyphosphoric acid (PPA), polypropylene (PP).

[0063] In other embodiments, the material of the partition 112 may be a combination of at least two of the above-mentioned materials, and the specific number of materials and the ratio between the various materials may be adjusted according to design requirements.

[0064] In one embodiment, please refer to Figure 3 and Figure 4 The outer casing 11 may include a first casing 113 having a receiving cavity 11a and a insertion interface 11c, and a second casing 114 having a product storage cavity 11b and an opening 11d. The insertion interface 11c is located at one end of the first casing 113 along a first direction, and the second casing 114 is disposed on one side of the first casing 113 along a second direction. That is, the receiving cavity 11a and the product storage cavity 11b can also be formed by providing two casings respectively.

[0065] Please see Figure 3 and Figure 4 The first housing 113 is provided with an interface 11c, one end of which can protrude from the second housing 114 in the first direction.

[0066] The end of the first housing 113 with the insertion interface 11c can also be flush with the second housing 114.

[0067] For an aerosol generating apparatus having a cover 12, where the opening 11d and the insertion interface 11c are located at the same end in the first direction, please refer to [example description would be inserted here]. Figure 3 and Figure 4 The first housing 113, with its insertion interface 11c, protrudes at least along the first direction from the closed cover 12. In other words, when the cover 12 is closed, the end of the first housing 113 with the insertion interface 11c protrudes along the first direction from the cover 12. This arrangement minimizes the length of the second housing 114 along the first direction while still accommodating the aerosol-generating product, resulting in a more compact and lighter overall structure for the aerosol-generating device.

[0068] For example, please refer to Figure 5 and Figure 6 The first housing 113 has a first outer surface 113a at one end where the insertion interface 11c is provided, and the cover 12 has a second outer surface 12a on the side away from the second housing 114. When the cover 12 is closed, the second outer surface 12a can also be flush with the first outer surface 113a, so that the outer surface of the aerosol generating device tends to be flat.

[0069] The first housing 113 and the second housing 114 can be connected together by adhesive. In order to achieve a better heat insulation effect, for example, the aerosol generating device can be provided with a heat insulation adhesive layer, and the first housing 113 and the second housing 114 are bonded together by the heat insulation adhesive layer.

[0070] The thermal insulation adhesive layer is formed by applying a thermal insulation adhesive between the first housing 113 and the second housing 114.

[0071] For example, the heat-insulating adhesive may be a mixture of a heat-resistant adhesive material and an aerogel heat-insulating film, and the heat-insulating adhesive may be an inorganic or organic adhesive.

[0072] For example, the heat resistance range of the heat-insulating adhesive can be 20°C to 1000°C (including the endpoint values).

[0073] The thickness of the thermal insulation adhesive layer can be adjusted according to design requirements. Preferably, the thickness of the thermal insulation adhesive layer can be 0.01mm to 5mm (including the endpoint values). For example, the thickness of the thermal insulation adhesive layer can be 0.01mm, 1mm, 3mm, 5mm, etc.
