In the heated but non-combustible aerosol generating matrix, the aerosol generating matrix is ​​heated by an external heat source to a level sufficient to release aerosols. The aerosol generating matrix does not burn; instead, it is loaded with a smoke-generating agent, and aerosols are released by heating the aerosol generating matrix during use.

[0003] The matrix units of the aerosol generation matrix segment are mainly in the form of flakes, filaments, and granules. In the related technologies where the matrix units are granular, the filling process for filling the matrix units has the problem of unstable suction resistance. Moreover, the vibration and other effects during the transportation and storage of granular matrix units will cause the granular matrix units in the local area of ​​the aerosol generation matrix segment to become more and more compact, resulting in greater suction resistance and a poor suction experience.

[0014] In one embodiment, the substrate layer is formed by casting the substrate layer on both sides along the thickness direction of the sheet-like matrix.

[0015] In one embodiment, the number of winding layers of the sheet-like substrate is a single layer or multiple layers.

[0016] In one embodiment, the sheet-like matrix is ​​wound into a circle, the base layer is wound into a cylindrical space, and the matrix strip is wrapped within the cylindrical space.

[0047] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0048] Please refer to Figures 6 to 9. An embodiment of this application provides an aerosol generation matrix segment 100.

[0049] It should be noted that the aerosol generating matrix segment 100 in this embodiment can be used for suction by ignition or by heating without combustion. In this embodiment, the aerosol generating matrix segment 100 is described as being used for suction by heating without combustion.

[0050] Please refer to Figure 10. This application also provides an aerosol generating article 1000, which includes a functional segment, an outer wrapping layer 600, and an aerosol generating matrix segment 100 according to any embodiment of this application.

[0051] The aerosol generation matrix segment 100 extends along a first direction. Exemplarily, the first direction is the direction shown by L in FIG10.

[0052] It should be noted that the aerosol generating article 1000 extends in the same direction as the aerosol generating matrix section 100. That is, the aerosol generating article 1000 also extends along the first direction.

[0053] The functional section is located at one end of the aerosol generating matrix section 100 along the first direction. The functional section includes a cooling section 300 and a filtration section 200, with the cooling section 300 located between the filtration section 200 and the aerosol generating matrix section 100. An outer wrapping layer 600 wraps around the outer periphery of the functional section and the aerosol generating matrix section 100.

[0054] The aerosol generating product 1000 is used in conjunction with an aerosol generating device having a heating component. Specifically, the heating component heats and atomizes the aerosol generating matrix section 100 to generate aerosol, and the user draws the filtered aerosol through the filter section 200.

[0055] There are various heating methods for the heating components. For example, heating methods include center heating and peripheral heating. Center heating refers to the heating component being inserted into the aerosol generating matrix section 100 to bake and heat the aerosol generating matrix section 100 from the inside out. Peripheral heating refers to the heating component being positioned around the aerosol generating product 1000 to bake and heat the aerosol generating matrix section 100 from the outside in. These heating methods can specifically include resistance heating, electromagnetic induction heating, infrared heating, microwave heating, laser heating, air heating, electric field heating, carbon source heating, plasma heating, etc., and are not specifically limited here.

[0056] The heating component heats the aerosol generating matrix section 100, causing it to release aerosols. The user inhales the aerosol in batches; that is, the user inhales one breath of aerosol, stops, and then inhales the next breath, thus inhaling intermittently. The initial inhalation period refers to the initial use of the aerosol generating matrix section 100, with the first few inhalations corresponding to this initial period, such as inhalations 1-5. The later inhalation period refers to the period when the aerosol generating matrix section 100 is close to complete aerosol release, with the last few inhalations corresponding to this later period, such as the last 1-5 inhalations. The initial and later inhalation periods respectively refer to the early and late stages of the aerosol generating matrix section 100's lifespan. The middle inhalation period refers to the inhalation time between the initial and later inhalation periods.

[0057] The cooling section 300 is located between the filtration section 200 and the aerosol generation matrix section 100 to cool the aerosol before the filtration section 200 filters it, thereby reducing the temperature of the aerosol and alleviating the "burning" sensation when the user inhales the aerosol.

[0058] It should be noted that the aerosol generating product 1000 relies on the aerosol generating matrix section 100 to generate aerosols. The functional section generally does not generate aerosols, but some aerosol generating products 1000 may add flavoring substances such as popping beads to the functional section.

[0059] The material of the outer wrapping layer 600 is not limited, for example, including but not limited to one or more combinations of materials such as fiber paper, metal foil, infrared radiation layer, metal foil composite fiber paper, polyethylene composite fiber paper, PE, PBAT, etc.

[0060] The outer wrapping layer 600 can be in the form of a hollow tube. The aerosol generating matrix segment 100 and the functional segment can be arranged sequentially in the hollow tube-shaped outer wrapping layer 600. The outer wrapping layer 600 can also be a splicing paper. The aerosol generating matrix segment 100 and the functional segment are combined into an integrated structure through the splicing paper.

[0061] The first direction is the arrangement direction of the aerosol generating matrix section 100, the cooling section 300 and the filtration section 200. The aerosol generating product 1000 is inserted into the aerosol generating device along the first direction, and the aerosol generating product 1000 is also taken out of the aerosol generating device along the first direction. The length of the aerosol generating matrix section 100 along the first direction can be longer, shorter or the same as the length in other directions.

[0062] For example, when the outer contour of the aerosol generating matrix segment 100 is cylindrical, the first direction is the axial direction of the aerosol generating matrix segment 100. It should be noted that the axial length of the aerosol generating matrix segment 100 can be less than its diameter.

[0063] For example, when the aerosol generating matrix section 100 has a cuboid shape, the first direction is still the direction defined above, that is, the arrangement direction of the aerosol generating matrix section 100, the cooling section 300 and the filtration section 200, or the direction in which the aerosol generating product 1000 is placed or removed from the aerosol generating device. The first direction of the aerosol generating matrix section 100 can be any of the length, width and height of the cuboid.

[0064] In related technologies, the matrix units of the aerosol generation matrix segment are mainly in the form of flakes, filaments, and granules. In related technologies where the matrix units are granular, the matrix units are filled through a filling process, which has the problem of unstable suction resistance. Furthermore, the vibration and other effects during the transportation and storage of granular matrix units can cause the granular matrix units in local areas of the aerosol generation matrix segment to become increasingly compact, resulting in greater suction resistance and a poor suction experience.

[0065] The aerosol generation matrix segment 100 provided in this application embodiment includes a sheet matrix 1. The aerosol generation matrix segment 100 is constructed as a wound structure formed by winding the sheet matrix 1. The sheet matrix 1 can be heated to generate aerosols. The sheet matrix 1 includes a base layer 10 and a matrix strip 20. The base layer 10 has a matrix strip 20 disposed on at least one side along the thickness direction of the sheet matrix 1.

[0066] Please refer to Figures 1 to 5. The sheet-like matrix 1 includes a base layer 10 and matrix strips 20 stacked together. The matrix strips 20 are laid on the base layer 10 to form the sheet-like matrix 1. The sheet-like matrix 1 with the matrix strips 20 distributed on its surface is rolled up to form a spiral aerosol generating matrix segment 100. That is to say, the aerosol generating matrix segment 100 is not a randomly filled aerosol generating matrix particles or other materials. The aerosol generated by the sheet-like matrix 1 can flow along the spiral sheet-like matrix 1. The amount of smoke felt during inhalation is large, and a stable airway can be formed by adjusting the size of the matrix strips 20, thereby improving the stability of the suction resistance.

[0067] Here, the matrix strip 20 is laid on the base layer 10, which allows for control over the distribution of the matrix strip 20. This helps to reduce displacement caused by factors such as vibration during transportation, storage, or use, thereby further improving the stability of the suction resistance.

[0068] It should be noted that the matrix strip 20 in the aerosol generation matrix segment 100 of this application embodiment can be any type of matrix strip 20 described below, or it can be a combination of different matrix strips 20.

[0069] The ability of sheet matrix 1 to be heated to generate aerosol means that either matrix strip 20 can be heated to generate aerosol, or both base layer 10 and matrix strip 20 can be heated to generate aerosol.

[0070] The matrix strip 20 can be laid on the surface of the base layer 10, or a portion of the matrix strip 20 can be embedded in the base layer 10.

[0071] The aerosol generation matrix segment 100 of this embodiment is configured as a wound structure formed by winding a sheet matrix 1. The sheet matrix 1 includes a base layer 10 and matrix strips 20 stacked together. This allows for the formation of stable air channels by adjusting the size of the matrix strips 20, thereby improving the stability of the suction resistance. Furthermore, the matrix strips 20, laid on the base layer 10, help reduce displacement caused by vibration or other factors during transportation, storage, or use, further improving the stability of the suction resistance. In addition, the matrix strips 20 are a homogeneous system, which facilitates the continuous and uniform generation of aerosols.

[0072] In some embodiments, please refer to Figures 1 to 5, the base layer 10 includes a substrate layer, which includes plant fiber fabric, non-woven fabric and / or metal foil.

[0073] In other words, the substrate layer can be plant fiber fabric, non-woven fabric, metal foil, or both non-woven fabric and metal foil.

[0074] Here, the metal foil not only provides support but also facilitates heat transfer, thereby improving atomization efficiency and rapid smoke output, and ultimately enhancing the vaping experience.

[0075] Plant fiber fabrics and non-woven fabrics have high air permeability, which increases air permeability; in addition, plant fiber fabrics and non-woven fabrics also have the functions of cushioning and elasticity, which is beneficial to the cooperation between the heating component and the aerosol generation matrix section 100.

[0076] In other embodiments, please refer to Figures 1 to 5, the base layer 10 includes a matrix layer, which is constructed by forming a matrix slurry by casting, spraying or dipping, and the matrix layer can be heated to generate an aerosol.

[0077] Both the matrix layer and matrix strip 20 can be heated to generate aerosols, which is conducive to rapid smoke explosion and large smoke volume. Furthermore, the aerosols generated by the matrix layer and matrix strip 20 can mix and interact with each other, which can increase the comfort of the aerosols and improve the inhalation quality.

[0078] In related technologies where the matrix unit is granular, the matrix unit is filled using a filling process. However, the filling process suffers from low production efficiency and unstable suction resistance.

[0079] This application mainly uses casting and extrusion processes. The matrix layer is formed by casting matrix slurry, which has high production efficiency. The matrix strips 20 are adhered to the matrix layer. By adjusting the size and distribution of the matrix strips 20, sufficient air channels can be formed. After the matrix strips 20 are fixed, the relative position changes little, which helps to reduce the displacement caused by vibration and other factors, thereby improving the stability of suction resistance.

[0080] In some embodiments, the matrix slurry includes a base material, glycerin, a broadleaf fiber solution, a flavoring, and a nicotine preparation and / or a cooling agent.

[0081] The broad-leaved fibers here include, but are not limited to, poplar, Eucalyptus grandis, and mulberry branches.

[0082] It is understandable that broadleaf plant fibers are natural plant materials, which can reduce the preparation cost of aerosol generation matrix particles and reduce the possibility that aerosol generation matrix particles will produce unpleasant odors and / or harmful gases when heated.

[0083] The base material includes plant materials, fillers, and adhesives.

[0084] For example, plant-based raw materials include one or more of the following: wheat flour, rice flour, cassava flour, buckwheat flour, oat flour, sweet potato flour, ophiopogon japonicus powder, kudzu root powder, carrot powder, honeysuckle powder, dandelion powder, loofah sponge powder, etc.

[0085] For example, the filler includes one or more of calcium carbonate, calcium chloride, magnesium chloride, calcium phosphate, etc.

[0086] For example, the adhesive includes one or more of carrageenan, konjac gum, locust bean gum, guar gum, xanthan gum, sodium alginate, agar, etc.

[0087] In some embodiments, by weight, 30-35 parts of base material, 20-25 parts of glycerin, 10-15 parts of broadleaf fiber solution, 10-15 parts of fragrance, and 1-2 parts of nicotine preparation and / or cooling agent are mixed to form a matrix slurry, wherein the broadleaf fiber solution is an aqueous solution with a mass fraction of 2.5%.

[0088] Here, a certain amount of water can also be added to the above mixed ingredients as needed, for example, 10-15 parts water.

[0089] In this embodiment, the matrix slurry with the above-mentioned ratio has good fluidity, allowing it to be quickly and uniformly cast, and enabling glycerin and fragrances to be mixed in as much as possible, thereby increasing the loading of effective substances in the matrix layer. It should be noted that any other suitable ratio can also be used to prepare the matrix slurry.

[0090] For example, the substrate layer can be heated using a three-stage hot air heating system, with the three stages having temperatures of 70-75℃, 75-80℃, and 90-95℃ respectively. Before the substrate layer enters the heating stage, aerosol-generating substrate particles are laid on the surface of the substrate layer to adhere to it. Depending on the requirements for different smoke volumes, continuous number of puffs, winding methods, and other indicators, the distribution of the aerosol-generating substrate particles can be uniform, irregular, or intermittent strip-like.

[0091] It should be noted that the number of layers of the sheet matrix 1 is not limited here.

[0092] In some embodiments, as shown in Figures 6 and 7, the sheet-like matrix 1 has a single layer of winding.

[0093] The sheet-like matrix 1 has a single layer, meaning that there is no overlapping area of ​​the sheet-like matrix 1 along the radial direction of the aerosol generation matrix segment 100. Of course, there can be an overlapping area at the connection between the first and last ends of the sheet-like matrix 1 to improve the reliability of the connection between the first and last ends.

[0094] Setting the number of winding layers of the sheet matrix 1 to a single layer is beneficial to improving heating efficiency, thereby improving fog production efficiency and ensuring good fog production consistency.

[0095] For example, in an embodiment where the number of winding layers of the sheet matrix 1 is a single layer, the thickness of the base layer 10 can be increased, and the particle size of the aerosol-generating matrix particles can be enlarged. This allows for improved heating efficiency through peripheral heating. Furthermore, it enables the formation of stable air channels within the sheet matrix 1, thereby improving the stability of the suction resistance.

[0096] In some embodiments, as shown in Figures 8 and 9, the sheet-like matrix 1 has multiple winding layers.

[0097] In the embodiments of this application, "multi-layer" refers to two or more layers.

[0098] Here, the number of winding layers of the sheet-like matrix 1 can be, for example, 2, 3, 4, 5, 6, 7, 8 or more.

[0099] For example, in an embodiment where the number of winding layers of the sheet matrix 1 is multi-layered, the thickness of the base layer 10 can be reduced, the particle size of the aerosol-generating matrix particles can be reduced, and it can be applied to different heating methods.

[0100] In this embodiment, by setting the number of winding layers of the sheet matrix 1 to multiple layers, a stable air passage can be formed between adjacent layers, which is beneficial to improving the stability of the suction resistance.

[0101] In some embodiments, please refer to FIG7, the sheet matrix 1 is wound into a circle, the base layer 10 is wound into a cylindrical space 10a, and the matrix strip 20 is wrapped inside the cylindrical space 10a.

[0102] Therefore, by adjusting the size of the matrix strip 20, a stable air passage can be formed, thereby improving the stability of the suction resistance. Furthermore, after the matrix strip 20 is laid on the base layer 10, it helps to reduce displacement caused by vibration and other factors during transportation, storage, or use, thus further improving the stability of the suction resistance. In addition, the matrix strip 20 is a homogeneous system, which is beneficial for the continuous and uniform generation of aerosols.

[0103] In some embodiments, referring to FIG7, each matrix strip 20 extends along the central axis of the aerosol generating matrix segment 100, and each matrix strip 20 is arranged at circumferential intervals along the cylindrical space 10a.

[0104] In this way, airflow channels 1a can be formed between each matrix strip 20, and airflow channels 1a are also part of the cylindrical space 10a11a.

[0105] In this embodiment, each matrix strip 20 extends axially along the aerosol generating matrix section, allowing airflow to flow axially along the aerosol generating matrix section and reducing suction resistance. Furthermore, the generated aerosol can be released through the airflow channel 1a, which helps increase the amount of vapor per puff, thereby ensuring a good vaping experience.

[0106] In some embodiments, as shown in Figure 7, an airflow channel is formed between at least two adjacent matrix strips 20.

[0107] Here, airflow channels can be formed between any two adjacent matrix strips 20, or airflow channels can be formed between some adjacent matrix strips 20.

[0108] The airflow channel 1a extends along the axial direction of the aerosol generating matrix section 100 and passes through both ends of the aerosol generating matrix section 100. When aerosol is drawn in, the airflow can pass through the airflow channel 1a along the axial direction of the aerosol generating matrix section 100. The generated aerosol is released through the airflow channel 1a and the airflow carries it away from the aerosol generating matrix section 100. This helps to reduce the suction resistance of the aerosol generating product 1000 and improve the suction experience of the aerosol generating product 1000.

[0109] In some embodiments, the thickness of the matrix layer is 0.2 mm to 1.5 mm.

[0110] The thickness of the matrix layer can be any one of 0.2mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, or 1.5mm, or any combination thereof.

[0111] Here, the thickness of the matrix layer can be determined based on the number of winding layers of the sheet matrix 1. As the number of winding layers increases, the thickness of the matrix layer decreases.

[0112] In this embodiment, by setting the thickness of the matrix layer to 0.2mm-1.5mm, the aerosol generation matrix section 100 can have appropriate absorption resistance while also generating sufficient smoke.

[0113] In some embodiments, the density of the matrix layer is 0.6 g / cm³. 3 -0.9g / cm 3 .

[0114] The density of the matrix layer can be 0.6 g / cm³. 3 0.65g / cm 3 0.68g / cm 3 0.7g / cm 3 0.72g / cm 3 0.75g / cm 3 0.78g / cm 3 0.8g / cm 3 0.85g / cm 3 0.88g / cm 3 0.9g / cm 3 The point value of any one of them or the point value between any two.

[0115] In this embodiment, the density of the matrix layer is set to 0.6 g / cm³. 3 -0.9g / cm 3This allows the matrix layer to have an appropriate density, enabling it to generate a large amount of smoke quickly and efficiently, while also ensuring that the matrix layer produces a sufficient amount of smoke.

[0116] In some embodiments, the density of the substrate layer is 0.5 g / cm³. 3 -1g / cm 3 .

[0117] The density of the basal layer can be 0.5 g / cm³. 3 0.55g / cm 3 0.58g / cm 3 0.6g / cm 3 0.65g / cm 3 0.68g / cm 3 0.7g / cm 3 0.72g / cm 3 0.75g / cm 3 0.78g / cm 3 0.8g / cm 3 0.85g / cm 3 0.88g / cm 3 0.9g / cm 3 0.95g / cm 3 0.98g / cm 3 1g / cm 3 The point value of any one of them or the point value between any two.

[0118] In this embodiment, the density of the substrate layer is set to 0.5 g / cm³. 3 -1g / cm 3 This allows for an appropriate density of the substrate layer and provides it with a certain degree of thermal conductivity. Furthermore, in embodiments where the substrate layer includes a matrix layer, the matrix layer's density can be appropriately adjusted, enabling it to generate a large amount of smoke quickly while also ensuring sufficient smoke output.

[0119] In some embodiments, referring to Figures 1 to 5, the base layer 10 further includes a substrate layer, which is constructed by casting a substrate slurry onto the substrate layer. The substrate layer includes plant fiber fabric, nonwoven fabric, and / or metal foil.

[0120] In other words, the substrate layer can be non-woven fabric, metal foil, or both.

[0121] Here, the metal foil not only provides support but also facilitates heat transfer, thereby improving atomization efficiency and rapid smoke output, and ultimately enhancing the vaping experience.

[0122] Non-woven fabric can carry fragrance and increase breathability; in addition, non-woven fabric also has the functions of cushioning and elasticity, which is beneficial to the cooperation between the heating component and the aerosol generation matrix section 100.

[0123] Here, by setting the base layer 10 to include a substrate layer and a matrix layer, on the one hand, it facilitates the casting of the matrix layer and also has a supporting role and / or fragrance carrying, buffering, and elasticity role. On the other hand, both the matrix layer and the matrix strip 20 can be heated to generate aerosols, which is conducive to the rapid explosion of smoke and a large amount of smoke. Moreover, the aerosols generated by the matrix layer and the matrix strip 20 can mix and interact with each other, which can increase the comfort of the aerosol and improve the smoking quality.

[0124] In some embodiments, a substrate layer is formed by casting on both sides of the sheet matrix 1 along the thickness direction.

[0125] This is beneficial for increasing the loading of effective substances in the sheet matrix 1, and when one layer is heated, the other layer will be preheated, which is conducive to the continuous and rapid bursting of smoke.

[0126] Here, the number of matrix layers, effective material loading, density, and thickness on both sides of the substrate layer along the thickness direction of the sheet matrix 1 can be the same or different.

[0127] Here, by casting the substrate layer on both sides along the thickness direction of the sheet matrix 1 to form a matrix layer, it is beneficial to increase the loading of effective substances, thereby improving the amount of smoke.

[0128] In some embodiments, as shown in Figures 3 and 4, substrate strips 20 are provided on both sides of the substrate layer 10 along the thickness direction of the sheet-like substrate 1.

[0129] This is beneficial for increasing the loading of effective substances in the sheet matrix 1, and when one layer is heated, the other layer will be preheated, which is conducive to the continuous and rapid bursting of smoke.

[0130] Here, the effective material loading, density, and thickness of the substrate strips 20 on both sides of the substrate layer along the thickness direction of the sheet matrix 1 can be the same or different.

[0131] Here, by providing matrix strips 20 on both sides of the base layer 10 along the thickness direction of the sheet matrix 1, it is beneficial to increase the loading of effective substances, thereby increasing the amount of smoke.

[0132] In some embodiments, please refer to FIG5, the base layer 10 has two layers, and the matrix strip 20 is disposed between the two base layers 10.

[0133] This facilitates the formation of a stable airway between the matrix strip 20 and the two base layers 10, and the two base layers 10 provide support, making it easier for the sheet matrix 1 to be rolled up, thereby improving the roundness of the aerosol generation matrix segment 100 of the sheet matrix 1.

[0134] In some embodiments, the matrix strip 20 is configured to be formed by extrusion of extruded raw materials, and the matrix strip 20 can be heated to generate an aerosol.

[0135] The matrix strip 20 is constructed by extruding raw materials. The extruded matrix strip 20 is a homogeneous system that can continuously and uniformly generate aerosols. After atomization, it will not fall off and affect the air passage or contaminate the aerosol generation device, thus improving the user experience. In addition, the extrusion process is relatively simple, has a large production capacity, stable quality, and high production efficiency.

[0136] In some embodiments, the extruded raw materials include the main raw material, glycerin, flavoring, and nicotine preparations and / or cooling agents.

[0137] For example, the main raw materials include one or more of wheat flour, rice flour, corn flour, soybean flour, potato flour, kudzu root flour, pea flour, sweet potato flour, ophiopogon japonicus flour, cassava flour, etc., or protein powder, starch, fiber, etc. obtained by separating the above raw materials.

[0138] In some embodiments, by weight, 50-70 parts of main raw material, 25-30 parts of glycerin, 15-25 parts of flavoring, and 1-2 parts of nicotine preparation and / or cooling agent are mixed to form an extrusion raw material.

[0139] Here, a certain amount of water can also be added to the above mixed ingredients as needed, for example, 10-15 parts water.

[0140] In this embodiment, the extrusion raw material with the above-mentioned ratio has good flowability, allowing for better extrusion and enabling glycerin and fragrances to be mixed in the extrusion raw material as much as possible, thereby increasing the loading of effective substances in the matrix strip 20. It should be noted that any other suitable ratio can also be used to prepare the extrusion raw material.

[0141] In some embodiments, the maximum diameter of the cross-section of the matrix strip 20 is 1 mm to 2 mm.

[0142] The maximum diameter of the cross-section of the substrate strip 20 can be any one of 1mm, 1.2mm, 1.3mm, 1.5mm, 1.6mm, 1.8mm, or 2mm, or any value between two of them.

[0143] Here, the maximum diameter refers to the maximum distance between two points on the cross-section of the matrix strip 20.

[0144] The cross section of the matrix strip 20 refers to the section obtained on the section perpendicular to the extension direction of the matrix strip 20.

[0145] Here, the cross-sectional shape of the matrix strip 20 is not limited. For example, the cross-sectional shape of the matrix strip 20 can be circular, elliptical, polygonal, or other irregular shapes.

[0146] In this embodiment, the matrix strip 20 has a small cross-section. When the matrix strip 20 is actually applied to the aerosol generation product 1000, it helps to increase the filling amount, thereby improving the suction experience of the aerosol generation product 1000.

[0147] In some embodiments, the degree of expansion of the matrix strip 20 is greater than or equal to 0.75.

[0148] The degree of expansion of the matrix strip 20 can be any one of 0.75, 0.78, 0.8, 0.82, 0.85, 0.88, 0.9, 0.92, 0.95, 0.98, 1 or any value between two of them.

[0149] The matrix strip 20 is extruded and expanded to form a porous structure. By setting the degree of expansion of the matrix strip 20 to be greater than or equal to 0.75, it is beneficial to the drying of the matrix strip 20 and the rapid release of smoke components and fragrances during inhalation.

[0150] In some embodiments, there are multiple sheet-like substrates 1, and multiple sheet-like substrates 1 are stacked and then wound to form an aerosol to generate a substrate segment 100.

[0151] Here, by stacking multiple sheet-like substrates 1 and then winding them to form an aerosol generating substrate segment 100, it is beneficial to reduce the number of winding turns.

[0152] In this embodiment, the multiple sheet-like matrix layers can be the same or different.

[0153] It should be noted that there are no restrictions on the arrangement of multiple sheet-like matrix layers.

[0154] For example, in some embodiments, the matrix strips 20 of two adjacent sheet-like matrix 1 are arranged close to each other. That is, the matrix strips 20 are stacked facing each other, which is beneficial to the adhesion reliability of the matrix strips 20 and improves the roundness of the aerosol generating medium segment during the winding process.

[0155] In other embodiments, the base layers 10 of two adjacent sheet-like substrates 1 are disposed close to each other. That is, the base layers 10 are stacked face to face, especially when aluminum foil material is used, because its rapid heat conduction allows the interior of the substrate strip 20 to be heated more fully.

[0156] In some embodiments, the base layer 10 of one of two adjacent sheet-like substrates 1 is positioned close to the substrate strip 20 of the other. This is beneficial for airway stability and heat transfer.

[0157] The embodiments of this application also provide a method for preparing aerosol generating medium particles, the method comprising the following steps.

[0158] Step S101: Prepare extrusion raw materials by mixing the main raw materials, glycerin, flavoring, nicotine preparation and / or cooling agent evenly to obtain extrusion raw materials.

[0159] By weight, 50-70 parts of main raw material, 25-30 parts of glycerin, 15-25 parts of flavoring, and 1-2 parts of nicotine preparation and / or cooling agent are mixed to form extrusion raw material.

[0160] Here, a certain amount of water can also be added to the above mixed ingredients as needed, for example, 10-15 parts water.

[0161] For example, the main raw materials include one or more of wheat flour, rice flour, corn flour, soybean flour, potato flour, kudzu root flour, pea flour, sweet potato flour, ophiopogon japonicus flour, cassava flour, etc., or protein powder, starch, fiber, etc. obtained by separating the above raw materials.

[0162] In this embodiment, the extrusion raw material with the above-mentioned ratio has good flowability, allowing for better extrusion and enabling glycerin and fragrances to be mixed in the extrusion raw material as much as possible, thereby increasing the loading of effective substances in the matrix strip 20. It should be noted that any other suitable ratio can also be used to prepare the extrusion raw material.

[0163] Step S102: Prepare the matrix slurry by mixing the base material, glycerin, broadleaf fiber solution, fragrance, nicotine preparation and / or cooling agent evenly to obtain the matrix slurry.

[0164] Here, the order of steps S101 and S102 is not particularly limited, and they can be performed simultaneously.

[0165] By weight, 30-35 parts of base material, 20-25 parts of glycerin, 10-15 parts of broadleaf fiber solution, 10-30 parts of flavoring, and 1-2 parts of nicotine preparation and / or cooling agent are mixed to form a matrix slurry, wherein the broadleaf fiber solution is an aqueous solution with a mass fraction of 2.5%.

[0166] The base material includes plant materials, fillers, and adhesives.

[0167] For example, plant-based raw materials include one or more of the following: wheat flour, rice flour, cassava flour, buckwheat flour, oat flour, sweet potato flour, ophiopogon japonicus powder, kudzu root powder, carrot powder, honeysuckle powder, dandelion powder, loofah sponge powder, etc.

[0168] For example, the filler includes one or more of calcium carbonate, calcium chloride, magnesium chloride, calcium phosphate, etc.

[0169] For example, the adhesive includes one or more of carrageenan, konjac gum, locust bean gum, guar gum, xanthan gum, sodium alginate, agar, etc.

[0170] In this embodiment, the matrix slurry with the above-mentioned ratio has good fluidity, allowing it to be quickly and uniformly cast, and enabling glycerin and fragrances to be mixed in as much as possible, thereby increasing the loading of effective substances in the matrix layer. It should be noted that any other suitable ratio can also be used to prepare the matrix slurry.

[0171] For example, the substrate layer can be heated using a three-stage hot air heating system, with the three stages having temperatures of 70-75℃, 75-80℃, and 90-95℃ respectively. Before the substrate layer enters the heating stage, aerosol-generating substrate particles are laid on the surface of the substrate layer to adhere to it. Depending on the requirements for different smoke volumes, continuous number of puffs, winding methods, and other indicators, the distribution of the aerosol-generating substrate particles can be uniform, irregular, or intermittent strip-like.

[0172] Step S103: Casting. The slurry obtained in step S102 is cast onto an aluminum foil with a thickness of 0.01 to 0.015 mm or a nonwoven fabric weighing 12 to 50 g on a casting machine to form a matrix layer with a casting thickness of 0.2 to 1.5 mm.

[0173] The casting machine employs a three-stage hot air heating system, with temperatures of 70–75°C, 75–80°C, and 90–95°C respectively. Before the casting enters the heating stage, the particles obtained in step S103 are uniformly dispersed on the surface of the cast thin layer, allowing them to adhere to the thin layer. Depending on requirements such as smoke volume, number of continuous puffs, and winding method, the particle distribution can be irregular saturated distribution or intermittent strip distribution (equal spacing, unequal spacing, etc.). As an example, the positive electrode current collector can be made of metal foil, conductive polymer material, carbon material, or composite current collector. For instance, as a metal foil, pure metals, alloys, or surface-treated metals can be used, including but not limited to stainless steel, copper, aluminum, nickel, titanium, or silver.

[0174] For example, a coating layer is provided on the matrix layer. Depending on the requirements of different products such as aroma and cigarette structure, non-woven fabric or aluminum foil can be selected to cover the surface of the matrix layer.

[0175] For example, the weight of the coating layer when it is a nonwoven fabric is 12 to 20 g.

[0176] For example, when the coating layer is aluminum foil, the thickness is 0.01 to 0.015 mm.

[0177] The nonwoven fabric is pre-treated under a closed system and a positive pressure of 0.1–0.2 MPa to absorb 0.5–1.5 times its own weight in fragrance. The upper layer is then fixed to the casting film with quick-drying tobacco adhesive or degreased cotton thread.

[0178] Step S104: Extrusion. The extruded material obtained in step S101 is extruded through an extrusion device to obtain matrix strip 20.

[0179] Here, the order of steps S103 and S104 is not particularly limited, and they can be performed simultaneously.

[0180] For example, the extrusion temperature is 120°C-135°C.

[0181] For example, the screw speed of the extrusion device is 60 rpm to 100 rpm.

[0182] For example, the extrusion pressure is 1.0 MPa-1.5 MPa.

[0183] For example, the maximum diameter of the cross-section of the matrix strip 20 is 1 mm to 2 mm.

[0184] The maximum diameter of the cross-section of the substrate strip 20 can be any one of 1mm, 1.2mm, 1.3mm, 1.5mm, 1.6mm, 1.8mm, or 2mm, or any value between two of them.

[0185] Here, the maximum diameter refers to the maximum distance between two points on the cross-section of the matrix strip 20.

[0186] The cross section of the matrix strip 20 refers to the section obtained on the section perpendicular to the extension direction of the matrix strip 20.

[0187] Here, the cross-sectional shape of the matrix strip 20 is not limited. For example, the cross-sectional shape of the matrix strip 20 can be circular, elliptical, polygonal, or other irregular shapes.

[0188] In this embodiment, the matrix strip 20 has a small cross-section. When the matrix strip 20 is actually applied to the aerosol generation product 1000, it helps to increase the filling amount, thereby improving the suction experience of the aerosol generation product 1000.

[0189] In some embodiments, as shown in Figures 1 to 5, the degree of expansion of the matrix strip 20 is greater than or equal to 0.75.

[0190] The degree of expansion of the matrix strip 20 can be any one of 0.75, 0.78, 0.8, 0.82, 0.85, 0.88, 0.9, 0.92, 0.95, 0.98, 1 or any value between two of them.

[0191] The matrix strip 20 is extruded and expanded to form a porous structure. By setting the degree of expansion of the matrix strip 20 to be greater than or equal to 0.75, it is beneficial to the drying of the matrix strip 20 and the rapid release of smoke components and fragrances during inhalation.

[0192] For example, the die of the extrusion device has 80-100 holes distributed in a planar pattern. This helps to improve extrusion efficiency.

[0193] Step S105: Composite, the matrix strip 20 obtained by extrusion in step S104 is adhered to the matrix layer obtained in step S103 before it is dried, to obtain sheet matrix 1.

[0194] Here, the number and density of the substrate strips 20 are determined by the number and density of the substrate strips 20. Multiple extrusion units can also be used in parallel, with each extrusion unit producing the same or different number and density of substrate strips 20, and the spacing between them can also be the same or different. The substrate strips 20 are dried together with the substrate layer to obtain the sheet-like substrate 1.

[0195] Step S106: Rolling, the sheet matrix 1 is rolled up according to different requirements such as the number of suction ports, smoke volume, and smoke burst speed to obtain aerosol generation matrix segment 100.

[0196] For example, the substrate is cut into thin sheets of varying widths of 1.5–2.5 cm, rolled into cylinders in different directions (1–3 turns), and then cut into medium segments of 12–20 mm in length. After cutting, one end is sealed with PLA (polylactic acid) mesh to prevent the medium from falling into the cooling section. The rolling method can be either inward or outward rolling of the substrate strip 20.

[0197] Through the above measures, the average smoke volume of 1001-3 puffs in the aerosol generation matrix section is greater than 4.0 mg / puff, the average smoke volume of 1-13 puffs is greater than 5.0 mg / puff, the effective utilization rate of VG / PG / NIC reaches more than 70%, and the RSD of the total smoke volume and total NIC release of the same number of puffs in different aerosol generation matrix sections is less than 10%.

[0198] Step S106: Assembly. The aerosol generation matrix section 100 obtained in step S105 is assembled with other components such as plugs / cooling sections (sealing section and cooling section are connected) / filters to form a finished product that can be used in smoking devices with circumferential or central needle heating.

[0199] In one embodiment, referring to Figure 10, the aerosol generation matrix section 100, the cooling section 300, and the filtration section 200 can be coaxially arranged cylinders, with the first direction being the axial direction of the aerosol generation matrix section 100, the cooling section 300, and the filtration section 200.

[0200] It is understandable that during the user's suction process, the aerosol generated by the aerosol generation matrix section 100 flows towards the filter section 200 in the first direction.

[0201] In one embodiment, referring to FIG10, the aerosol generating article 1000 further includes a breathable sealing element 500 disposed at at least one end of the aerosol generating matrix section 100.

[0202] The sealing element 500 is a membrane through which airflow can pass.

[0203] For example, the sealing element 500 can be cigarette paper, non-woven fabric, polymer, etc., which have good air permeability.

[0204] For example, the permeability of the sealing element 500 can be greater than or equal to 500 CU (CU is cm). 3 / (min*cm 2 (abbreviation of *kpa).

[0205] A sealing element 500 can be installed at one end of the aerosol generating matrix section 100 near the cooling section 300. That is, the aerosol generated by the aerosol generating matrix section 100 can pass through the sealing element 500 and enter the airflow channel, where it will be cooled. Here, the sealing element 500 can block the aerosol generating matrix section 100 to prevent the aerosol generating matrix section 100 or its aerosol generating matrix particles from accidentally entering the airflow channel (for example, the centrally heated heating element pushing the aerosol generating matrix section 100 into the airflow channel). This prevents the aerosol generating matrix section 100 or its aerosol generating matrix particles from entering the airflow channel, thus reducing the number of heatable aerosol generating matrix sections 100 and affecting the heating effect. It also prevents the aerosol generating matrix section 100 from blocking the airflow channel and affecting the suction resistance.

[0206] A sealing element 500 can also be installed at the end of the aerosol generating matrix section 100 away from the cooling section 300. Here, the sealing element 500 prevents aerosol generating matrix particles within the aerosol generating matrix section 100 from falling out and remaining inside the aerosol generating device. Furthermore, the condensate after aerosol condensation will also largely prevent leakage and residue inside the aerosol generating device. Therefore, when using an aerosol generating product 1000 with this structure, the aerosol generating device achieves higher cleanliness, and when the aerosol generating device draws in aerosol generating products 1000 of different flavors, cross-contamination of flavors is virtually eliminated.

[0207] In other embodiments, sealing elements 500 can also be covered at opposite ends of the airflow channel, thereby eliminating the need to distinguish the assembly direction of the cooling section 300 during the assembly of the aerosol generating product 1000, thus improving the ease of assembly.

[0208] In one embodiment, the cooling section 300 has an airflow channel (not shown). The aerosol generation matrix section 100 enters the airflow channel and is cooled within the airflow channel.

[0209] In other embodiments, the cooling section 300 may also adopt other structural forms, as long as it can achieve the cooling effect.

[0210] In some embodiments, the aerosol generating article 1000 may not have a functional segment, that is, the aerosol generating matrix segment 100 can constitute the aerosol generating article 1000 on its own, for use in some special aerosol generating devices. For example, the aerosol generating device includes a nozzle and a cooling component, which can be reused or used once, simply by inserting or removing the aerosol generating matrix segment 100 into the heating space.

[0211] In the above embodiments, the aerosol generation matrix segment 100 can be cylindrical, sheet-like, square, etc., and can be adapted according to the characteristics of the heating component and the aerosol generation device.

[0212] In one embodiment, referring to FIG10, the aerosol generating article 1000 further includes a front plug section 400, which is disposed at one end of the aerosol generating matrix section 100 away from the functional section along a first direction.

[0213] During use, the front plug section 400 of the aerosol generating product 100 can effectively reduce the probability of the aerosol generating matrix section 100 falling out of the outer wrapping layer 600.

[0214] The aerosol generating product 1000 has a distal lip end and a proximal lip end at its two ends along the first direction. The proximal lip end refers to the end of the aerosol generating product 1000 that is closer to the user when using it, while the distal lip end refers to the end of the aerosol generating product 1000 that is farther away from the user when using it. The front plug section 400 is located at the distal lip end of the aerosol generating product 1000. This effectively prevents aerosol condensation from flowing downwards and remaining in the container of the aerosol generating device, thus avoiding contamination and difficulty in cleaning the container. It also prevents cross-contamination of flavors when inhaling different flavored aerosol generating products 1000.

[0215] During the process of removing the aerosol-generated product 1000 from the receiving chamber of the aerosol generating device, even if adhesion occurs between the heating component and the aerosol generating matrix section 100, the front plug section 400 can push the aerosol generating matrix section 100 to move away from the receiving chamber, thereby facilitating the separation of the heating component and the aerosol generating matrix section 100 and making it easier for the aerosol-generated product 1000 to be taken out from the receiving chamber of the aerosol generating device.

[0216] In one embodiment, referring to Figure 10, the front plug section 400 is a hollow tube structure. That is, the front plug section 400 has an internal channel that runs through the end of the front plug section 400 away from the aerosol generating matrix section 100 and the end near the aerosol generating matrix section 100. The heating component can pass through the internal channel and be inserted into the aerosol generating matrix section 100. By setting the front plug section 400 as a hollow tube structure, the resistance encountered by the aerosol generating article 1000 during insertion into the receiving chamber of the aerosol generating device is relatively low, which is convenient for user operation.

[0217] In one embodiment, the pre-plug section 400 is made of a breathable material. This allows airflow to pass relatively smoothly through the pre-plug section 400, thereby reducing the suction resistance of the aerosol-generating article 1000 and improving the user's suction experience.
