[0002] This application is based on and claims priority to Chinese Patent Application No. 202411104621.4, filed on August 12, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of smoke-generating products, and in particular to an aerosol-generating product and an aerosol-generating system. Background Technology

[0004] Aerosol generating articles can form aerosols by ignition or by heating without combustion (HNB). In HNB aerosol generating articles, the aerosol generating article is heated by an external heat source to a level sufficient to release aerosols. The aerosol generating article does not burn; instead, it is loaded with a smoke-generating agent. During use, the aerosol generating article is heated to release the smoke-generating agent and form an aerosol.

[0005] In existing aerosol generation systems, the matrix segment and the functional segment are manufactured separately. During the manufacturing process of aerosol generated products, the matrix segment and the functional segment need to be combined and twisted together in multiple ways, which results in complicated production processes, low production efficiency, and high manufacturing costs. Furthermore, the combination and splicing of the matrix segment and the functional segment is detrimental to the aerosol transport efficiency. Summary of the Invention

[0072] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0073] Please see Figures 2 to 11 This application provides an aerosol generating article 10, which includes at least one assembly unit 15. The assembly unit 15 includes a matrix segment 11 and at least one first functional segment. The at least one first functional segment and the matrix segment 11 are arranged along a first direction, and the at least one first functional segment and the matrix segment 11 are an integral structure. At least the matrix segment 11 can be heated to generate aerosol.

[0074] In this embodiment, the example is described using a matrix segment 11 that is suitable for suction in a heated but non-combustible manner.

[0075] This application also provides an aerosol generation system 100, please refer to... Figure 1 The aerosol generation system 100 includes the aerosol generation article 10 and the aerosol generation device 20 according to any embodiment of this application.

[0076] The aerosol generating product 10 is used in conjunction with the aerosol generating device 20, which is used to heat the aerosol generating product 10.

[0077] Aerosol generating article 10 is used to generate aerosols when heated for users to inhale.

[0078] In this embodiment, the aerosol-generated article 10 is generally cylindrical. The cylindrical shape can be circular (i.e., with a circular cross-section), prismatic (i.e., with a polygonal cross-section), elliptical (i.e., with an elliptical cross-section), or irregular cylindrical, etc., and is not limited thereto.

[0079] Here, the number of aerosol generating products 10 in the aerosol generating device 20 can be one or more.

[0080] In the embodiments of this application, "multiple" refers to two or more items.

[0081] For example, the matrix segment 11 includes an aerosol generating agent for forming an aerosol.

[0082] Exemplarily, the matrix segment 11 extends along a first direction. Exemplarily, the first direction is... Figures 4 to 6 The direction indicated by L in the middle.

[0083] It should be noted that the aerosol generating article 10 extends in the same direction as the matrix segment 11. That is, the aerosol generating article 10 also extends along the first direction.

[0084] The combined unit 15 includes at least one first functional segment, which is arranged along a first direction with the matrix segment 11.

[0085] It should be noted that, Figures 5 to 11 The lines shown between the different first functional segments, and between the matrix segment and the first functional segment, are used to distinguish between the different first functional segments, or between the matrix segment and the first functional segment. These lines may or may not be present in the actual product. In embodiments where they are absent, they can be distinguished by density, relative position, concentration of the loading material, etc.

[0086] Please see Figure 1 and Figure 5 The first direction is the arrangement direction of the matrix segment 11 and the first functional segment. The aerosol generating product 10 is inserted into the aerosol generating device 20 along the first direction. The matrix segment 11 is closer to the heating element 22. The aerosol generating product 10 is also taken out from the aerosol generating device 20 along the first direction. The length of the matrix segment 11 along the first direction can be longer, shorter, or the same as the length in other directions.

[0087] For example, when the external outline of the combined unit 15 is cylindrical, the first direction is the axial direction of the combined unit 15. It should be noted that the axial length of the combined unit 15 can be less than its diameter.

[0088] For example, when the external outline of the combined unit 15 is a cuboid, the first direction is still the direction defined above, that is, the arrangement direction of the matrix segment 11 and the first functional segment, or the direction of taking and placing the aerosol generating product 10 on the aerosol generating device 20. The first direction of the combined unit 15 can be any of the length, width and height of the cuboid.

[0089] The aerosol-generating article 10 may include one or more combined units 15.

[0090] Please see Figure 8 and Figure 9 The combination unit 15 may include a first functional segment; please refer to [link / reference]. Figures 5 to 7 , Figure 10 as well as Figure 11 It can also include multiple first functional segments. In embodiments where the number of first functional segments is multiple, the multiple first functional segments and the matrix segment 11 are all integral structures.

[0091] The aerosol generating article 10 provided in this application includes a combination unit 15, which includes a matrix segment 11 and at least one first functional segment. The first functional segment and the matrix segment 11 are integrally formed, meaning that the first functional segment and the matrix segment 11 can be integrally molded. The matrix segment 11 can be heated to generate aerosol, and the first functional segment can work in conjunction with the matrix segment 11 to improve the inhalation experience. Thus, when manufacturing the aerosol generating article 10, the first functional segment and the matrix segment 11 can be integrally molded, eliminating the need to manufacture the matrix segment 11 and the functional segment separately, and eliminating the need for multi-component composite splicing of the matrix segment 11 and the functional segment. This simplifies the production process, improves production efficiency, and reduces manufacturing costs. Furthermore, compared to the combined and spliced ​​matrix segment and the first functional segment, the integrally molded first functional segment and matrix segment are beneficial for improving the aerosol transport efficiency within the matrix segment and the first functional segment.

[0092] In some embodiments, the assembly unit 15 is configured to be formed from at least one substrate 151 extending along a first direction. The substrate 151 is configured to be formed from a plant containing a plurality of parallel-arranged natural through-holes. The interior of the substrate 151 has a plurality of airflow channels 152, the natural through-holes forming the airflow channels 152. At least a portion of the substrate 151 is loaded with a load that can generate aerosols or aromas.

[0093] The composite unit 15 can be formed from one substrate 151 or from multiple substrates 151.

[0094] The substrate 151 is constructed from plants containing multiple parallel-arranged natural through-holes. That is, the substrate 151, made from plants, inherently possesses numerous natural through-holes, which form airflow channels 152. This facilitates the formation of more airflow channels 152 within the substrate 151, thereby improving the production efficiency of the functional sections. Furthermore, using naturally derived plants as the substrate 151 ensures biodegradability and environmental friendliness.

[0095] Because plants containing multiple parallel-arranged natural through-holes have high porosity, the composite unit 15 formed by the matrix 151 can have appropriate suction resistance, thereby improving the suction experience.

[0096] The matrix 151 is a structural framework and does not generate aerosols.

[0097] In addition, the raw materials for matrix 151 are relatively widely available and the cost of obtaining them is relatively low, which helps to reduce the manufacturing cost of functional segments and improve production efficiency; and the matrix 151 itself has relatively good temperature resistance and basically does not produce odor after heating, which helps to improve the taste of aerosol.

[0098] For example, the substrate 151 includes at least one of bamboo, wood, kudzu, wisteria, akebia, grapevine, astragalus root, codonopsis root, rush stem, water onion stem, sugarcane, corn, sorghum, and reed. That is, the substrate 151 can be one of bamboo, wood, kudzu, wisteria, akebia, grapevine, astragalus root, codonopsis root, rush stem, water onion stem, sugarcane, corn, sorghum, and reed, or it can be multiple of bamboo, wood, kudzu, wisteria, akebia, grapevine, astragalus root, codonopsis root, rush stem, water onion stem, sugarcane, corn, sorghum, and reed.

[0099] For example, the substrate 151 is prepared by pretreatment of a plant containing a plurality of parallel-arranged natural through-holes.

[0100] For example, pretreatment involves acid washing followed by foaming to remove lignin, hemicellulose, and other substances from the plant. The characteristic aroma of the pretreated plant is thus removed.

[0101] In this embodiment, the assembly unit 15 is constructed from at least one substrate 151, which is made from a plant containing multiple parallel-arranged natural through-holes. This allows the natural through-holes of the plant to form airflow channels 152 within the substrate 151, providing the assembly unit 15 with appropriate suction resistance. Furthermore, the assembly unit 15, formed from a plant containing natural through-holes, exhibits high-temperature resistance, improving its structural stability and reducing the likelihood of deformation and melting upon heating. This mitigates the impact of collapsing airflow channels 152 on suction resistance and airflow channel blockage caused by the release of impurities, thus enhancing the user experience. Additionally, the substrate 151, constructed from a plant containing multiple parallel-arranged natural through-holes, facilitates aerosol transport within these natural through-holes, further improving the aerosol transport efficiency between the matrix segment and the first functional segment.

[0102] In some embodiments, the matrix 151 of the matrix segment 11 is loaded with a load that can generate an aerosol.

[0103] For example, the loading material includes at least an aerosol generating agent.

[0104] The loading material can be a loading liquid, and the matrix 151 of the matrix segment 11 can be an adsorption loading liquid. The adsorption method can be soaking, injection, spraying or dripping. The loading liquid includes one or more of tobacco powder, non-tobacco plant powder, aerosol generating agent, flavoring agent, taste agent and nicotine.

[0105] The method of loading the substrate 151 with the loading material is not limited. For example, the loading material can be injected into the substrate 151 by quantitative injection; or the substrate 151 can be immersed in a liquid loading material slurry and then removed and dried for shaping; or the substrate 151 can be immersed in a liquid loading material slurry, filled under pressure, and then dried for shaping.

[0106] It should be noted that after the matrix segment 11 is processed and shaped, the load will solidify into a solid.

[0107] The loading material includes at least an aerosol generating agent, which is used to generate an aerosol when heated for the user to inhale.

[0108] In some embodiments, the loading may further include a smoke-generating component. The smoke-generating component is used to produce smoke upon heating, thereby synergistically working with the aerosol-generating agent and plant-based components to ensure an adequate amount of aerosol generation.

[0109] For example, the smoke-generating agent may include one or more combinations of: monohydric alcohols (such as menthol); polyhydric alcohols (such as propylene glycol, glycerol, triethylene glycol, 1,3-butanediol, and tetraethylene glycol); esters of polyhydric alcohols (such as triacetin, triethyl citrate, mixtures of diacetins, triethyl citrate, methylbenzyl benzoate, and triglyceride); monocarboxylic acids; dicarboxylic acids; polycarboxylic acids (such as lauric acid and myristic acid) or aliphatic esters of polycarboxylic acids (such as dimethyl dodecanoate, dimethyl tetradecanoate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, triacetin, mesoerythritol, mixtures of diacetins, diethyl octanoate, triethyl citrate, methylbenzyl benzoate, phenylacetic acid, ethyl vanillate, triglyceride, and lauryl acetate).

[0110] In some embodiments, the porosity of the matrix 151 is in the range of 50% to 98%.

[0111] The porosity of the matrix 151 can be any one of 50%, 52%, 53%, 54%, 55%, 58%, 60%, 61%, 63%, 64%, 65%, 68%, 70%, 72%, 73%, 75%, 77%, 80%, 82%, 83%, 85%, 86%, 90%, 92%, 93%, 95%, 98%, or any value between two of them.

[0112] It should be noted that the porosity of the substrate 151 refers to the ratio of the sum of the volumes of all airflow channels 152 inside the substrate 151 to the volume of the substrate 151.

[0113] Porosity can be determined according to the method specified in YC / T 473-2013 "Determination of Apparent Density, True Density and Internal Pore Volume of Tobacco".

[0114] Here, when the porosity of the matrix 151 is too small, it may result in a large absorption resistance of the matrix 151, which will greatly limit the generation and migration of aerosols. When the porosity of the matrix 151 is too large, it may result in a small absorption resistance of the matrix 151, which may result in insufficient stiffness of the matrix 151.

[0115] Thus, by setting the porosity of the matrix 151 to be in the range of 50% to 98%, the adsorption resistance of the matrix 151 can be appropriate, which is conducive to the generation and migration of aerosols, and it also has a certain stiffness.

[0116] Preferably, the porosity of the matrix 151 is in the range of 70% to 95%.

[0117] In some embodiments, the density of the matrix 151 is 0.03 g / cm³. 3Up to 0.3 g / cm 3 The range.

[0118] The density of matrix 151 can be 0.03 g / cm³. 3 0.05g / cm 3 0.06g / cm 3 0.08g / cm 3 0.1g / cm 3 0.12g / cm 3 0.13g / cm 3 0.15g / cm 3 0.16 g / cm 3 0.17g / cm 3 0.2g / cm 3 0.22g / cm 3 0.23g / cm 3 0.24g / cm 3 0.25g / cm 3 0.26g / cm 3 0.28g / cm 3 0.3g / cm 3 The point value of any one of them or the point value between any two.

[0119] Here, when the density of the matrix 151 is too high, it may result in a large suction resistance of the matrix 151 and a small load on the load, which will lead to a small amount of smoke and a greater restriction on the generation and migration of aerosols. When the density of the matrix 151 is too low, it may result in insufficient stiffness of the matrix 151, a small amount of smoke, poor consistency of the matrix 151, and low smoking satisfaction.

[0120] Thus, by setting the density of matrix 151 to 0.05 g / cm³ 3 Up to 0.3 g / cm 3 The range can take into account the suction resistance, stiffness and load on the substrate 151, which is beneficial to improve the consistency of the aerosol product 10 and the suction satisfaction.

[0121] Preferably, the density of the matrix 151 is 0.1 g / cm³. 3 Up to 0.24 g / cm 3 The range.

[0122] In some embodiments, airflow channels 152 with an equivalent diameter of 1 μm to 2 mm account for more than 90% of all airflow channels 152 in the substrate 151.

[0123] In other words, the ratio of the number of airflow channels 152 with an equivalent diameter of 1 μm to 2 mm in the substrate 151 to the total number of airflow channels 152 in the substrate 151 is greater than or equal to 90%.

[0124] It is understandable that airflow channels 152 with an equivalent diameter of less than 1 μm are easily blocked by the load or other substances. If there are too many airflow channels 152 with an equivalent diameter of less than 1 μm, the suction resistance of the substrate 151 after loading the load will increase, and the suction resistance may decrease during use, affecting the consistency of taste. If there are too many airflow channels 152 with an equivalent diameter of more than 2 mm, the suction resistance of the substrate 151 will be smaller, and the load capacity of the substrate 151 on the load will be reduced.

[0125] Therefore, by setting the ratio of the number of airflow channels 152 with an equivalent diameter of 1μm to 2mm in the substrate 151 to the total number of airflow channels 152 in the substrate 151 to be greater than or equal to 90%, the suction resistance of the substrate 151 and the load on the load can be balanced, and the change in the suction resistance of the substrate 151 during use can be reduced, thereby improving the consistency of taste.

[0126] It should be noted that the natural through-holes of the plant can be exactly the same as the airflow channel 152 of the substrate 151, or the natural through-holes of the plant can be formed into the airflow channel 152 of the substrate 151 after processing, that is, the size and / or shape of the natural through-holes are different from the size and / or shape of the airflow channel 152.

[0127] The natural through-holes of a plant can extend only in the first direction or extend radially along the plant.

[0128] In some embodiments, the ratio of the sum of the cross-sectional areas of all airflow channels 152 with equivalent diameters in the range of 0.01 mm to 0.3 mm to the cross-sectional area of ​​the substrate 151 in a cross section perpendicular to the first direction is in the range of 10% to 60%.

[0129] In this way, the absorption resistance of the matrix 151 can be appropriate, which is conducive to the generation and migration of aerosols, and also has a certain stiffness.

[0130] In some embodiments, in a cross section perpendicular to the first direction, the average equivalent diameter of all airflow channels 152 with an equivalent diameter greater than or equal to 10 μm is in the range of 0.05 mm to 0.8 mm.

[0131] In some embodiments, the elastic recovery rate of the matrix 151 in the radial direction is in the range of 76% to 98%.

[0132] The elastic recovery rate of the matrix 151 in the radial direction refers to the percentage of the matrix 151 that recovers its original shape or size after deformation under external force and the removal of the external force. Its core principle is based on the elastic mechanical properties of the material; the higher the value, the stronger the resistance to permanent deformation.

[0133] By setting the radial elastic recovery rate of the matrix 151 to be in the range of 76% to 98%, the structural strength, stability and porosity of the matrix 151 can be balanced.

[0134] In some embodiments, the radial hardness of the substrate 151 is in the range of 70% to 95%.

[0135] Radial hardness is a mechanical property index of the local resistance of the matrix 151 to indentation deformation, reflecting the ability of the matrix 151 to resist surface deformation under pressure.

[0136] The radial hardness of the substrate 151 can be measured by indentation: apply radial pressure to the surface of the substrate 151 and calculate the hardness value based on the indentation depth or area.

[0137] By setting the radial hardness of the matrix 151 to a range of 70% to 95%, the structural strength, stability, and porosity of the matrix 151 can be balanced.

[0138] In some embodiments, the tensile strength of the matrix 151 in the first direction is in the range of 5 kN / m to 30 kN / m.

[0139] Tensile strength, also known as tensile strength or breaking strength, represents the breaking force per unit area.

[0140] Tensile strength is the maximum load that causes the matrix 151 to fracture in the first direction starting from the original cross-section.

[0141] The measurement standard can be a horizontal tensile strength measuring instrument.

[0142] The tensile strength of the matrix 151 in the first direction can be any one of 5 kN / m, 6 kN / m, 7 kN / m, 8 kN / m, 9 kN / m, 10 kN / m, 12 kN / m, 13 kN / m, 15 kN / m, 16 kN / m, 17 kN / m, 18 kN / m, 19 kN / m, 20 kN / m, 21 kN / m, 23 kN / m, 25 kN / m, 26 kN / m, 27 kN / m, 29 kN / m, or 30 kN / m, or a value between any two.

[0143] Here, by setting the tensile strength of the matrix 151 in the first direction to be in the range of 5 kN / m to 30 kN / m, the situation of matrix 151 breaking and falling off can be improved, which is beneficial to improving the amount of smoke, the stability of suction and the yield. In addition, in embodiments where the matrix segment 11 includes the matrix 151, the matrix segment 11 can also be made into a homogeneous system, which is beneficial to the continuous and uniform generation of aerosol.

[0144] In some embodiments, the tensile strength of the matrix 151 in the direction perpendicular to the first direction is in the range of 0.5 kN / m to 10 kN / m.

[0145] The tensile strength of the matrix 151 in the direction perpendicular to the first direction can be any one of 0.5 kN / m, 0.6 kN / m, 0.7 kN / m, 0.8 kN / m, 0.9 kN / m, 1 kN / m, 1.5 kN / m, 2 kN / m, 2.5 kN / m, 3 kN / m, 3.5 kN / m, 4 kN / m, 4.5 kN / m, 5 kN / m, 6 kN / m, 7 kN / m, 8 kN / m, 9 kN / m, and 10 kN / m, or any value between two of them.

[0146] Here, by setting the tensile strength of the matrix 151 in the direction perpendicular to the first direction to be in the range of 0.5 kN / m to 10 kN / m, both the structural strength and porosity of the matrix 151 can be taken into account.

[0147] It should be noted that the specific structural forms of the matrix 151 are varied.

[0148] In some embodiments, please refer to Figures 8 to 11 The substrate 151 has a columnar structure, and the composite unit 15 is composed of a single substrate 151.

[0149] The columnar structure can be cylindrical (i.e., with a circular cross-section), prismatic (i.e., with a polygonal cross-section), elliptical (i.e., with an elliptical cross-section), or irregular columnar, etc., without any restrictions.

[0150] In some embodiments, please refer to Figures 8 to 11 The combined unit 15 is composed of a single base 151.

[0151] In other embodiments, please refer to Figure 2 The composite unit 15 is formed by the aggregation of multiple bases 151.

[0152] Here, the multiple bases 151 can be arranged in parallel or intertwined with each other.

[0153] In other embodiments, please refer to Figure 3 and Figure 4The substrate 151 has a sheet-like structure, and the assembly unit 15 is formed by winding or folding at least one substrate 151.

[0154] The combined unit 15 can be formed by winding or folding a base 151, or by winding or folding multiple bases 151.

[0155] Here, the number of the first functional segments can be one or more.

[0156] In some embodiments, please refer to Figure 8 At least one first functional segment includes a pre-plug segment 14, which is located at the distal lip end of the matrix segment 11, and the pre-plug segment 14 and the matrix segment 11 are an integral structure.

[0157] In this embodiment, the aerosol generating product 10 is composed of a combination unit 15 (including a front plug section 14 and a matrix section 11), a forming paper tube, a filter section 12 (second functional section), a cooling section 13 (second functional section), and a tipping paper.

[0158] The front plug section 14 is located at one end of the matrix section 11 and at the distal lip of the aerosol generating product 10. On the one hand, during use, the front plug section 14 mainly serves to isolate and support, effectively reducing the probability of the matrix section 11 falling off the outer wrapping layer; on the other hand, it can also effectively prevent the aerosol from condensing and flowing downwards and remaining in the receiving chamber 21 of the aerosol generating device 20, thus causing internal contamination of the receiving chamber 21 and making it difficult to clean, and also preventing cross-contamination of flavors when drawing different flavored aerosol generating products 10.

[0159] Because plants contain multiple parallel-arranged natural through-holes, the pre-plug section 14, which uses plants as the substrate 151, has a relatively large number of natural through-holes, which can increase the surface area of ​​the pre-plug section 14. The pre-plug section 14 can adsorb the refluxed condensed aerosol, improving the situation where the aerosol condensate flows back into the receiving chamber 21 of the aerosol generating device 20, thus improving the leakage prevention effect of the pre-plug section 14.

[0160] Furthermore, since the front plug section 14 is located close to the matrix section 11, it can improve the situation where the temperature of the matrix section 11 is transferred to the front plug section 14 and deforms and melts. It can also improve the situation where the release of impurities affects the suction resistance due to the collapse of the airflow channel 152 and blocks the airflow channel 152.

[0161] The density range of the fore-plug section 14 is 0.05 g / cm³. 3 -0.25g / cm 3 If the density is too low, the isolation and leakage prevention effect will be poor; if the density is too high, it will affect the airflow.

[0162] In some embodiments, the substrate 151 has a columnar structure, the total length of the front plug section 14 and the matrix section 11 is in the range of 12 mm to 50 mm, and the equivalent diameter of the combined unit 15 is in the range of 4 mm to 15 mm.

[0163] The total length of the fore-plug section 14 and the matrix section 11 can be any one of 12mm, 13mm, 15mm, 18mm, 20mm, 25mm, 28mm, 30mm, 35mm, 38mm, 40mm, 42mm, 43mm, 45mm, 48mm, or 50mm, or any one of the two.

[0164] By setting the total length of the front plug section 14 and the matrix section 11 to be in the range of 12mm to 50mm, the length of the matrix section 11 can be appropriate, so that the aerosol generating product 10 can generate enough aerosols, while the length of the front plug section 14 can be appropriate, so that the backflow aerosol after the suction is completed can be effectively adsorbed, improving the condensation of aerosols in the aerosol generating device 20, while making the suction resistance of the front plug section 14 appropriate.

[0165] The equivalent diameter of the combined unit 15 can be any one of 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, and 15mm, or any combination thereof.

[0166] Here, the equivalent diameter of a single substrate 151 can be in the range of 4mm to 15mm. Alternatively, the equivalent diameter of multiple substrates 151 gathered together to form a combined unit 15 can also be in the range of 4mm to 15mm.

[0167] For example, multiple substrates 151 can be compressed and placed into a forming paper tube, or two or more strips can be spliced ​​together to form a cylinder or cuboid, then compressed and placed into a forming paper tube.

[0168] In some embodiments, the substrate 151 has a sheet-like structure, and the assembly unit 15 is formed by winding at least one substrate 151. The length of the substrate 151 is in the range of 12 mm to 50 mm, the width of the substrate 151 is in the range of 10 mm to 50 mm, and the thickness of the substrate 151 is in the range of 2 mm to 7.5 mm.

[0169] For example, the thickness of the substrate 151 corresponding to the region of the matrix segment 11 is in the range of 2 mm to 7.5 mm, or the thickness of the substrate 151 corresponding to the region of the foreplug segment 14 is in the range of 2.5 mm to 7.5 mm.

[0170] The substrate 151 can be a sheet structure with a length ranging from 12 mm to 50 mm and a width ranging from 10 mm to 50 mm, and the assembly unit 15 is formed by winding at least one of the substrate 151. That is, the length of the assembly unit 15 is in the range of 12 mm to 50 mm.

[0171] Here, the length of the base 151 can be greater than the width of the base 151, or the length of the base 151 can be less than the width of the base 151.

[0172] By adjusting parameters such as the width and thickness of the sheet-like substrate 151 and combining compression rolling, cylindrical structures with different densities of the front plug section 14 and the matrix section 11, or cylindrical tubular structures containing a single central through hole, can be obtained.

[0173] After being rolled, the sheet substrate 151 can be placed into a shaped paper tube or connected by adhesive bonding.

[0174] Here, the thickness of the region of the matrix 151 corresponding to the matrix segment 11 may be greater than the thickness of the region of the matrix 151 corresponding to the foreplug segment 14. In this case, the porosity of the matrix segment 11 is less than the porosity of the foreplug segment 14. Alternatively, the thickness of the region of the matrix 151 corresponding to the matrix segment 11 may be less than the thickness of the region of the matrix 151 corresponding to the foreplug segment 14. In this case, the porosity of the matrix segment 11 is greater than the porosity of the foreplug segment 14.

[0175] In some embodiments, at least a portion of the pre-plug segment 14 is loaded with a load that can generate aerosols or aromas, or the load amount of the load in the pre-plug segment 14 is less than or equal to the load amount of the load in the matrix segment 11, or the density of the pre-plug segment 14 is less than or equal to the density of the matrix segment 11.

[0176] For example, in addition to aerosol generating agents, the loading material may also include at least one of tobacco powder, non-tobacco plant powder, flavoring, fragrance, and nicotine.

[0177] By loading at least part of the front stopper section 14 with a load that can generate aerosols or aromas, it can serve as an aerosol supplement for the matrix section 11, thereby improving the consistency of taste and vapor performance.

[0178] In other words, the front plug section 14 may be partially loaded with a load, such as the area near the matrix section 11, or the entire front plug section 14 may be loaded with a load.

[0179] The load of the loading material in the fore-plug section 14 is less than that in the matrix section 11. In other words, the aerosol is mainly generated by the matrix section 11, and the aerosol generated by the fore-plug section 14 is used as a supplement.

[0180] In some embodiments, please refer to Figure 8The airflow channel 152 passes through the fore plug section 14 and the matrix section 11.

[0181] Due to the characteristic of plants containing multiple parallel-arranged natural straight pores, the interior of the substrate 151 prepared from plants has multiple straight airflow channels 152, thereby allowing the airflow channels 152 to pass through the integrally formed front plug section 14 and the substrate section 11.

[0182] Since the airflow channel 152 runs through the front plug section 14 and the matrix section 11, that is, the same airflow channel 152 can be formed inside the front plug section 14 and the matrix section 11 at the same time, it is beneficial for the external airflow to enter the matrix section 11 through the front plug section 14 and carry the aerosol generated by the matrix section 11 to the near lip end.

[0183] In some embodiments, please refer to Figure 9 At least one first functional segment includes a cooling segment 13, which is located near the lip end of the matrix segment 11, and the cooling segment 13 and the matrix segment 11 are an integral structure.

[0184] In this embodiment, the aerosol generating product 10 is composed of a combination unit 15 (including a cooling section 13 and a matrix section 11), a forming paper tube, a filter section 12 (second functional section), a front plug section 14 (second functional section), and a tipping paper.

[0185] The cooling section 13 can cool the flowing aerosol, improving the "burning" sensation when users inhale aerosols.

[0186] For example, the density range of the cooling section 13 is 0.04 g / cm³. 3 -0.25g / cm 3 If the density is too low, the processing strength is weak; if the density is too high, it will cause excessive cooling and form more condensate, which will affect the passage of aerosols.

[0187] For example, the cooling section 13 is a hollow tube, the interior of which has a hollow channel 131, and the wall density of the hollow tube is in the range of 0.08 g / cm³. 3 -0.25g / cm 3 .

[0188] Because plants contain multiple parallel natural through-holes, the cooling section 13 using plants as the substrate 151 has a relatively large number of natural through-holes. These natural through-holes can increase the surface area of ​​the cooling section 13, thereby improving the cooling effect on aerosols.

[0189] Furthermore, since the cooling section 13 is located close to the matrix section 11, it can improve the situation where the temperature of the matrix section 11 is transferred to the cooling section 13 and deforms and melts. It can also improve the situation where the release of impurities affects the suction resistance due to the collapse of the airflow channel 152 and blocks the airflow channel 152.

[0190] The aerosol generating product 10 is prepared by splicing the prepared combined unit 15 (including the cooling section 13 and the matrix section 11), the pre-stop section 14, and the filter section 12 together with splicing paper. The aerosol generating product 10 can be prepared by first preparing a cylindrical matrix 151, then adsorbing the loading liquid to form the combined unit 15, stabilizing it, and then placing it into a forming paper tube. Alternatively, the sheet-like or strip-like matrix 151 can be first adsorbed with the loading liquid, stabilized, and then rolled into a cylindrical shape and placed into a forming paper tube. The portion adsorbing the loading liquid can be a separate matrix section 11, or the cooling section 13 can be integrated with the matrix section 11. The loading capacity of the matrix section 11 is greater than that of the cooling section 13, or the cooling section 13 is at least partially loaded and partially unloaded. The pre-stop section 14 and the filter section 12 are made of materials such as cellulose acetate, polylactic acid, or polyester, or they can be the matrix 151 (e.g., foamed bamboo).

[0191] In some embodiments, the substrate 151 has a columnar structure, the total length of the cooling section 13 and the matrix section 11 is in the range of 30 mm to 70 mm, and the equivalent diameter of the combined unit 15 is in the range of 4 mm to 15 mm.

[0192] The total length of the cooling section 13 and the substrate section 11 can be any one of the following values: 30mm, 35mm, 38mm, 40mm, 42mm, 43mm, 45mm, 48mm, 50mm, 51mm, 53mm, 55mm, 57mm, 60mm, 62mm, 63mm, 65mm, 68mm, 70mm, or any value between the two.

[0193] By setting the total length of the cooling section 13 and the matrix section 11 to be in the range of 30mm to 70mm, the length of the matrix section 11 can be appropriate, so that the aerosol generating product 10 can generate enough aerosols, while the length of the cooling section 13 can be appropriate, so that the cooling section 13 can have sufficient cooling effect, and the suction resistance of the cooling section 13 can be appropriate.

[0194] The equivalent diameter of the combined unit 15 can be any one of 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, and 15mm, or any combination thereof.

[0195] Here, the equivalent diameter of a single substrate 151 can be in the range of 4mm to 15mm. Alternatively, the equivalent diameter of multiple substrates 151 gathered together to form a combined unit 15 can also be in the range of 4mm to 15mm.

[0196] In some embodiments, the substrate 151 has a sheet-like structure, and the assembly unit 15 is formed by winding at least one substrate 151. The length of the substrate 151 is in the range of 30 mm to 70 mm, the width of the substrate 151 is in the range of 10 mm to 50 mm, and the thickness of the substrate 151 corresponding to the region of the matrix segment 11 is in the range of 2 mm to 7.5 mm, or the thickness of the substrate 151 corresponding to the region of the cooling segment 13 is in the range of 1 mm to 4 mm.

[0197] The substrate 151 can be a sheet-like structure with a length ranging from 30 mm to 70 mm and a width ranging from 10 mm to 50 mm, and the assembly unit 15 is formed by winding at least one of the substrate 151. That is, the length of the assembly unit 15 is in the range of 30 mm to 70 mm.

[0198] Here, the length of the base 151 can be greater than the width of the base 151, or the length of the base 151 can be less than the width of the base 151.

[0199] By adjusting parameters such as the width and thickness of the sheet substrate 151 and combining compression rolling, cylindrical structures with different densities of cooling section 13 and matrix section 11, or cylindrical tubular structures containing a single central through hole, can be obtained.

[0200] After being rolled, the sheet substrate 151 can be placed into a shaped paper tube or connected by adhesive bonding.

[0201] Here, the thickness of the region of the substrate 151 corresponding to the matrix segment 11 can be greater than the thickness of the region of the substrate 151 corresponding to the cooling segment 13. In this case, the porosity of the matrix segment 11 is less than the porosity of the cooling segment 13. Alternatively, the thickness of the region of the substrate 151 corresponding to the matrix segment 11 can be less than the thickness of the region of the substrate 151 corresponding to the cooling segment 13. In this case, the porosity of the matrix segment 11 is greater than the porosity of the cooling segment 13.

[0202] In some embodiments, at least a portion of the cooling section 13 is loaded with a load that can generate aerosols or aromas, or the load amount of the load in the cooling section 13 is less than the load amount of the load in the matrix section 11, or the density of the cooling section 13 is less than the density of the matrix section 11.

[0203] For example, in addition to the aerosol generating agent, the loading may also include at least one of tobacco powder, tobacco pulp, flavoring, fragrance, and nicotine.

[0204] By loading at least part of the cooling section 13 with a load that can generate aerosols or aromas, aroma quality can be increased and puff consistency can be improved.

[0205] In other words, the cooling section 13 can be partially loaded with a load, such as the area near the matrix section 11, or the entire cooling section 13 can be loaded with a load.

[0206] The loading capacity of the cooling section 13 is less than that of the matrix section 11. In other words, the aerosol is mainly generated by the matrix section 11, and the cooling section 13 can increase the aroma quality.

[0207] In some embodiments, please refer to Figure 9 The airflow channel 152 runs through the cooling section 13 and the matrix section 11.

[0208] Due to the characteristic of plants containing multiple parallel natural straight pores, the interior of the substrate 151 prepared from plants has multiple straight airflow channels 152, thereby allowing the airflow channels 152 to pass through the integrally formed cooling section 13 and the substrate section 11.

[0209] Since the airflow channel 152 runs through both the cooling section 13 and the matrix section 11, meaning that the same airflow channel 152 can be formed simultaneously inside both the cooling section 13 and the matrix section 11, it is beneficial for the airflow generated in the matrix section 11 to directly enter the cooling section 13 through the airflow channel 152. The aerosol is cooled as it flows through the airflow channel 152 within the cooling section 13. In other words, the aerosol flows directly within the airflow channel 152 without passing through the wall of the cooling section 13, which helps reduce aerosol loss during flow and improves the suction experience.

[0210] In some embodiments, please refer to Figure 11 At least one first functional segment includes a front plug segment 14 and a cooling segment 13. The front plug segment 14 is located at the distal lip end of the matrix segment 11, and the cooling segment 13 is located at the proximal lip end of the matrix segment 11. The front plug segment 14, the matrix segment 11, and the cooling segment 13 are an integral structure.

[0211] In other words, when manufacturing the aerosol generating product 10, the front plug section 14, the matrix section 11, and the cooling section 13 can be integrally molded without the need to manufacture the front plug section 14, the matrix section 11, and the cooling section 13 separately, and without the need to perform multi-component composite twisting of the front plug section 14, the matrix section 11, and the cooling section 13. This simplifies the production process, improves production efficiency, and reduces manufacturing costs.

[0212] The aerosol generating product 10 is prepared by splicing the prepared combined unit 15 (including the pre-stop section 14, cooling section 13, and matrix section 11) and the filter section 12 together with splicing paper. The aerosol generating product 10 can be prepared by first preparing a cylindrical matrix 151, then adsorbing the loading liquid to form the combined unit 15, stabilizing it, and then placing it into a forming paper tube. Alternatively, the sheet-like or strip-like matrix 151 can be first adsorbed with the loading liquid, stabilized, and then rolled into a cylindrical shape and placed into a forming paper tube. The part adsorbing the loading liquid can be a separate matrix section 11, with the pre-stop section 14 integrated with the matrix section 11, the cooling section 13 integrated with the matrix section 11, or the pre-stop section 14, cooling section 13, and matrix section 11 integrated. The filter section 12 can be made of materials such as cellulose acetate, polylactic acid, or polyester, or it can be the matrix 151 (e.g., foamed bamboo).

[0213] In some embodiments, the substrate 151 has a columnar structure, the total length of the front plug section 14, the cooling section 13 and the matrix section 11 is in the range of 35 mm to 75 mm, and the equivalent diameter of the combined unit 15 is in the range of 4 mm to 15 mm.

[0214] The total length of the front plug section 14, the cooling section 13 and the matrix section 11 can be any one of the following values ​​or any combination of two: 35mm, 38mm, 40mm, 42mm, 43mm, 45mm, 48mm, 50mm, 51mm, 53mm, 55mm, 57mm, 60mm, 62mm, 63mm, 65mm, 68mm, 70mm, 73mm and 75mm.

[0215] By setting the total length of the front plug section 14, the cooling section 13, and the matrix section 11 to be within the range of 35mm to 75mm, the length of the matrix section 11 can be made appropriate, so that the aerosol generating product 10 can generate enough aerosols. At the same time, the length of the front plug section 14 can be made appropriate, so that it can effectively adsorb the backflow aerosol after the suction is completed, improving the condensation of aerosols in the aerosol generating device 20. This also makes the suction resistance of the front plug section 14 appropriate, and the length of the cooling section 13 can be made appropriate, so that the cooling section 13 has sufficient cooling effect and the suction resistance of the cooling section 13 is appropriate.

[0216] The equivalent diameter of the combined unit 15 can be any one of 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, and 15mm, or any combination thereof.

[0217] Here, the equivalent diameter of a single substrate 151 can be in the range of 4mm to 15mm. Alternatively, the equivalent diameter of multiple substrates 151 gathered together to form a combined unit 15 can also be in the range of 4mm to 15mm.

[0218] For example, multiple substrates 151 can be compressed and placed into a forming paper tube, or two or more strips can be spliced ​​together to form a cylinder or cuboid, then compressed and placed into a forming paper tube.

[0219] In some embodiments, the substrate 151 has a sheet-like structure, and the assembly unit 15 is formed by winding at least one substrate 151. The length of the substrate 151 is in the range of 35 mm to 75 mm, the width of the substrate 151 is in the range of 10 mm to 50 mm, the thickness of the substrate 151 corresponding to the region of the matrix segment 11 is in the range of 2 mm to 7.5 mm, or the thickness of the substrate 151 corresponding to the region of the front plug segment 14 is in the range of 2.5 mm to 7.5 mm, or the thickness of the substrate 151 corresponding to the region of the cooling segment 13 is in the range of 1 mm to 4 mm.

[0220] The substrate 151 can be a sheet structure with a length ranging from 35 mm to 75 mm and a width ranging from 10 mm to 50 mm, and the assembly unit 15 is formed by winding at least one of the substrate 151. That is, the length of the assembly unit 15 is in the range of 35 mm to 75 mm.

[0221] Here, the length of the base 151 can be greater than the width of the base 151, or the length of the base 151 can be less than the width of the base 151.

[0222] By adjusting parameters such as the width and thickness of the sheet-like substrate 151 and combining compression rolling, cylindrical structures with different densities of the front plug section 14 and the matrix section 11, or cylindrical tubular structures containing a single central through hole, can be obtained.

[0223] In some embodiments, please refer to Figure 11 The airflow channel 152 extends through the front plug section 14, the matrix section 11, and the cooling section 13; or, the density of both the front plug section 14 and the cooling section 13 is less than the density of the matrix section 11; or, the load of at least one of the front plug section 14 and the cooling section 13 is less than the load of the matrix section 11.

[0224] Due to the characteristic of plants containing multiple parallel natural straight pores, the interior of the substrate 151 made from plants has multiple straight airflow channels 152, thereby allowing the airflow channels 152 to pass through the integrally formed front plug section 14, substrate section 11 and cooling section 13.

[0225] Since the airflow channel 152 runs through the front plug section 14, the matrix section 11, and the cooling section 13, meaning that the same airflow channel 152 can be formed simultaneously inside the front plug section 14, the matrix section 11, and the cooling section 13, external airflow directly enters the matrix section 11 through the airflow channel 152 of the front plug section 14, and carries the aerosol generated in the matrix section 11 directly into the cooling section 13 through the airflow channel 152. The aerosol is cooled as it flows through the airflow channel 152 in the cooling section 13. In other words, the aerosol flows directly in the airflow channel 152 without passing through the walls of the front plug section 14, the matrix section 11, and the cooling section 13, which helps reduce aerosol loss during the flow process and improves the suction experience.

[0226] In some embodiments, please refer to Figure 10 At least one first functional segment includes a cooling segment 13 and a filtering segment 12. The cooling segment 13 is located near the lip end of the matrix segment 11, and the filtering segment 12 is located near the lip end of the cooling segment 13. The matrix segment 11, the cooling segment 13 and the filtering segment 12 are an integral structure.

[0227] In other words, when manufacturing aerosol generating product 10, the matrix section 11, cooling section 13 and filtration section 12 can be integrally molded without the need to manufacture the matrix section 11, cooling section 13 and filtration section 12 separately, and without the need to perform multi-component composite twisting of the matrix section 11, cooling section 13 and filtration section 12. This simplifies the production process, improves production efficiency and reduces manufacturing costs.

[0228] The aerosol generating product 10 is prepared by splicing the prepared combined unit 15 (including a matrix section 11, a cooling section 13, and a filtration section 12) and the pre-stop section 14 together with splicing paper. The aerosol generating product 10 can be prepared by first preparing a cylindrical matrix 151, then adsorbing the loading liquid to form the combined unit 15, stabilizing it, and then placing it into a forming paper tube. Alternatively, the sheet-like or strip-like matrix 151 can be first adsorbed with the loading liquid, stabilized, and then rolled into a cylindrical shape and placed into a forming paper tube. The part adsorbing the loading liquid can be a separate matrix section 11, with the cooling section 13 integrated with the matrix section 11. The pre-stop section 14 can be made of materials such as cellulose acetate, polylactic acid, or polyester, or it can be the matrix 151 (e.g., foamed bamboo).

[0229] In some embodiments, the substrate 151 has a columnar structure, the total length of the matrix section 11, the cooling section 13 and the filter section 12 is in the range of 35 mm to 75 mm, and the equivalent diameter of the combined unit 15 is in the range of 4 mm to 15 mm.

[0230] The total length of the substrate section 11, the cooling section 13 and the filter section 12 can be any one of 35mm, 38mm, 40mm, 42mm, 43mm, 45mm, 48mm, 50mm, 51mm, 53mm, 55mm, 57mm, 60mm, 62mm, 63mm, 65mm, 68mm, 70mm, 73mm and 75mm or any combination thereof.

[0231] By setting the total length of the matrix section 11, cooling section 13, and filtration section 12 to a range of 35mm to 75mm, the length of the matrix section 11 can be appropriate, so that the aerosol generating product 10 can generate sufficient aerosols. At the same time, the length of the cooling section 13 can be appropriate, so that the cooling section 13 has sufficient cooling effect and appropriate suction resistance. The length of the filtration section 12 can also be appropriate, so that the filtration section 12 has sufficient filtration effect and appropriate suction resistance.

[0232] The equivalent diameter of the combined unit 15 can be any one of 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, and 15mm, or any combination thereof.

[0233] Here, the equivalent diameter of a single substrate 151 can be in the range of 4mm to 15mm. Alternatively, the equivalent diameter of multiple substrates 151 gathered together to form a combined unit 15 can also be in the range of 4mm to 15mm.

[0234] For example, multiple substrates 151 can be compressed and placed into a forming paper tube, or two or more strips can be spliced ​​together to form a cylinder or cuboid, then compressed and placed into a forming paper tube.

[0235] In some embodiments, please refer to Figure 3 The substrate 151 has a sheet-like structure, and the assembly unit 15 is formed by winding at least one substrate 151. The length of the substrate 151 is in the range of 35 mm to 75 mm, the width of the substrate 151 is in the range of 10 mm to 50 mm, the thickness of the substrate 151 corresponding to the region of the matrix section 11 is in the range of 2 mm to 7.5 mm, or the thickness of the substrate 151 corresponding to the region of the filter section 12 is in the range of 2.5 mm to 7.5 mm, or the thickness of the substrate 151 corresponding to the region of the cooling section 13 is in the range of 1 mm to 4 mm.

[0236] The substrate 151 can be a sheet structure with a length ranging from 35 mm to 75 mm and a width ranging from 10 mm to 50 mm, and the assembly unit 15 is formed by winding at least one of the substrate 151. That is, the length of the assembly unit 15 is in the range of 35 mm to 75 mm.

[0237] Here, the length of the base 151 can be greater than the width of the base 151, or the length of the base 151 can be less than the width of the base 151.

[0238] By adjusting parameters such as the width and thickness of the sheet-like substrate 151 and combining compression rolling, cylindrical structures with different densities of the front plug section 14 and the matrix section 11, or cylindrical tubular structures containing a single central through hole, can be obtained.

[0239] In some embodiments, please refer to Figure 10 The airflow channel 152 passes through the matrix section 11, the cooling section 13 and the filter section 12, or the density of the filter section 12 and the cooling section 13 is less than the density of the matrix section 11, or the load of the matrix section 11 is greater than the load of the filter section 12 and the cooling section 13.

[0240] Due to the characteristic of plants containing multiple parallel natural straight pores, the interior of the substrate 151 prepared from plants has multiple straight airflow channels 152, thereby allowing the airflow channels 152 to pass through the integrally formed substrate section 11, cooling section 13 and filtration section 12.

[0241] Since the airflow channel 152 runs through the matrix section 11, the cooling section 13, and the filter section 12, meaning that the same airflow channel 152 can be formed simultaneously inside the matrix section 11, the cooling section 13, and the filter section 12, external airflow directly enters the matrix section 11 through the airflow channel 152, carrying the aerosol generated in the matrix section 11 directly into the cooling section 13. The aerosol is cooled as it flows through the airflow channel 152 in the cooling section 13, and then directly enters the filter section 12 through the airflow channel 152. In other words, the aerosol flows directly in the airflow channel 152 without passing through the walls of the front plug section 14, the matrix section 11, the cooling section 13, and the filter section 12, which helps reduce aerosol loss during the flow process and improves the suction experience.

[0242] In some embodiments, please refer to Figures 4 to 7 At least one first functional segment includes a front plug segment 14, a cooling segment 13 and a filter segment 12. The front plug segment 14 is located at the distal lip end of the matrix segment 11, the cooling segment 13 is located at the proximal lip end of the matrix segment 11, and the filter segment 12 is located at the proximal lip end of the cooling segment 13. The front plug segment 14, the matrix segment 11, the cooling segment 13 and the filter segment 12 are an integral structure.

[0243] In other words, when manufacturing the aerosol generating product 10, the front plug section 14, the matrix section 11, the cooling section 13, and the filter section 12 can be integrally molded, eliminating the need to manufacture the front plug section 14, the matrix section 11, the cooling section 13, and the filter section 12 separately, and eliminating the need to perform multi-component composite twisting of the front plug section 14, the matrix section 11, the cooling section 13, and the filter section 12. This simplifies the production process, improves production efficiency, and reduces manufacturing costs.

[0244] The preparation method of the aerosol generating product 10 is as follows: First, a combined unit 15 (including a pre-stop section 14, a matrix section 11, a cooling section 13, and a filter section 12) is prepared. That is, a cylindrical matrix 151 is prepared first, and then a loading liquid is adsorbed to form the combined unit 15. After stabilization, it is placed into a forming paper tube. Alternatively, a sheet-like or strip-like matrix 151 can be first adsorbed with the loading liquid, stabilized, and then rolled into a cylindrical shape and placed into a forming paper tube. The part that adsorbs the loading liquid can be a separate matrix section 11, the cooling section 13 can be integrated with the matrix section 11, the matrix section 11 can be integrated with the pre-stop section 14, or the cooling section 13, the pre-stop section 14, and the matrix section 11 can be integrated.

[0245] In some embodiments, the substrate 151 has a columnar structure, the total length of the front plug section 14, the matrix section 11, the cooling section 13 and the filter section 12 is in the range of 40 mm to 80 mm, and the equivalent diameter of the combined unit 15 is in the range of 4 mm to 15 mm.

[0246] The total length of the front plug section 14, the substrate section 11, the cooling section 13 and the filter section 12 can be any one of 40mm, 42mm, 43mm, 45mm, 48mm, 50mm, 51mm, 53mm, 55mm, 57mm, 60mm, 62mm, 63mm, 65mm, 68mm, 70mm, 73mm, 75mm, 78mm, 80mm or any combination thereof.

[0247] In other words, the cooling section 13 is located between the substrate section 11 and the filter section 12.

[0248] The aerosol generated by the heated aerosol generating product 10 can flow through the filter section 12, which can filter out large particles and unwanted impurities in the aerosol. In other words, the aerosol generated by the heated aerosol generating product 10 is filtered through the filter section 12 before being drawn in by the user.

[0249] The aerosol generated by the heated aerosol generating product 10 can first flow through the cooling section 13 for cooling. After cooling, the aerosol then flows through the filtration section 12, which can filter out large particles and unwanted impurities in the aerosol. In other words, the aerosol generated by the heated aerosol generating product 10 is cooled and filtered sequentially through the cooling section 13 and the filtration section 12 before being drawn in by the user.

[0250] By setting the total length of the pre-plug section 14, matrix section 11, cooling section 13, and filter section 12 to a range of 40mm to 80mm, the length of the matrix section 11 can be appropriate, allowing the aerosol generating product 10 to generate sufficient aerosols. Simultaneously, the length of the pre-plug section 14 can be appropriate, effectively adsorbing the recirculated aerosols after suction, improving aerosol condensation within the aerosol generating device 20, and ensuring appropriate suction resistance. Similarly, the length of the cooling section 13 can be appropriate, ensuring sufficient cooling effect and appropriate suction resistance. Finally, the length of the filter section 12 can be appropriate, ensuring sufficient filtration effect and appropriate suction resistance.

[0251] The equivalent diameter of the combined unit 15 can be any one of 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, and 15mm, or any combination thereof.

[0252] Here, the equivalent diameter of a single substrate 151 can be in the range of 4mm to 15mm. Alternatively, the equivalent diameter of multiple substrates 151 gathered together to form a combined unit 15 can also be in the range of 4mm to 15mm.

[0253] For example, multiple substrates 151 can be compressed and placed into a forming paper tube, or two or more strips can be spliced ​​together to form a cylinder or cuboid, then compressed and placed into a forming paper tube.

[0254] In some embodiments, please refer to Figure 4 The substrate 151 has a sheet-like structure, and the assembly unit 15 is formed by winding at least one substrate 151. The length of the substrate 151 is in the range of 40 mm to 80 mm, the width of the substrate 151 is in the range of 10 mm to 50 mm, the thickness of the substrate 151 corresponding to the region of the matrix section 11 is in the range of 2 mm to 7.5 mm, or the thickness of the substrate 151 corresponding to the region of the front plug section 14 is in the range of 2.5 mm to 7.5 mm, or the thickness of the substrate 151 corresponding to the region of the cooling section 13 is in the range of 1 mm to 4 mm, or the thickness of the substrate 151 corresponding to the region of the filter section 12 is in the range of 2.5 mm to 7.5 mm.

[0255] The substrate 151 can be a sheet structure with a length ranging from 40 mm to 80 mm and a width ranging from 10 mm to 50 mm, and the assembly unit 15 is formed by winding at least one of the substrate 151. That is, the length of the assembly unit 15 is in the range of 40 mm to 80 mm.

[0256] Here, the length of the base 151 can be greater than the width of the base 151, or the length of the base 151 can be less than the width of the base 151.

[0257] By adjusting parameters such as the width and thickness of the sheet-like substrate 151 and combining compression rolling, cylindrical structures with different densities of the front plug section 14 and the matrix section 11, or cylindrical tubular structures containing a single central through hole, can be obtained.

[0258] In some embodiments, please refer to Figures 4 to 7 The airflow channel 152 extends through the front plug section 14, the matrix section 11, the cooling section 13, and the filter section 12; or, the density of at least one of the filter section 12, the front plug section 14, and the cooling section 13 is less than or equal to the density of the matrix section 11; or, the load of at least one of the filter section 12, the front plug section 14, and the cooling section 13 is less than or equal to the load of the matrix section 11.

[0259] Due to the characteristic of plants containing multiple parallel-arranged natural straight pores, the interior of the substrate 151 made from plants has multiple straight airflow channels 152, thereby allowing the airflow channels 152 to pass through the integrally formed front plug section 14, substrate section 11, cooling section 13 and filter section 12.

[0260] Since the airflow channel 152 runs through the front plug section 14, the matrix section 11, the cooling section 13, and the filter section 12, meaning that the same airflow channel 152 can be formed simultaneously inside the front plug section 14, the matrix section 11, the cooling section 13, and the filter section 12, the external airflow directly enters the matrix section 11 through the airflow channel 152 of the front plug section 14, and carries the aerosol generated in the matrix section 11 directly into the cooling section 13 through the airflow channel 152. The aerosol is cooled when flowing through the airflow channel 152 in the cooling section 13, and then directly enters the filter section 12 through the airflow channel 152. In other words, the aerosol flows directly in the airflow channel 152 without passing through the walls of the front plug section 14, the matrix section 11, the cooling section 13, and the filter section 12, which helps to reduce aerosol loss during the flow process and improve the suction experience.

[0261] In some embodiments, the matrix 151 comprises cellulose, and the cellulose content in the matrix 151 is greater than or equal to 50%.

[0262] In other words, the ratio of the mass of cellulose in matrix 151 to the total mass of matrix 151 is greater than or equal to 50%.

[0263] In some embodiments, please refer to Figures 8 to 11 The aerosol generating product 10 includes a second functional segment, which is arranged along a first direction with a matrix segment 11, and the second functional segment and the matrix segment 11 are separate structures.

[0264] Exemplarily, in some embodiments, the second functional segment may be configured to be formed from at least one substrate 151 extending along a first direction, the substrate 151 being configured to be formed from a plant containing a plurality of parallel-arranged natural through-holes, the interior of the substrate 151 having a plurality of airflow channels 152, the natural through-holes forming the airflow channels 152, and at least a portion of the substrate 151 being loaded with a load that can generate aerosols or aromas.

[0265] In other words, the second functional segment is prepared from a plant containing multiple parallel-arranged natural through-holes.

[0266] In other embodiments, the second functional segment may be constructed from materials such as cellulose acetate, polylactic acid, and polyester.

[0267] For example, the second functional section may include at least one of the pre-plug section 14, the cooling section 13, or the filtering section 12.

[0268] It should be noted that, in some embodiments, the first functional segment, which is integrally formed with the matrix segment, does not carry any load. In some embodiments, the first functional segment carries the same load as the matrix segment. In some embodiments, the first functional segment carries a different load than the matrix segment. In some embodiments, the first functional segment itself does not carry any load, but during contact with the matrix segment, it will adsorb a certain amount of load from the matrix segment. In some embodiments, the first functional segment can carry all or part of the load, which can be designed according to the heating method.
