[0002] This disclosure is based on and claims priority to patent applications No. 202411844283.8, filed on December 13, 2024, and No. 202511150956.4, filed on August 15, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of smoke-generating products, and in particular to an aerosol-generating product. 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, aerosol products are difficult to clean, and the suction resistance of aerosol products is difficult to adjust. Summary of the Invention

[0006] In view of this, the present disclosure aims to provide an aerosol-generating article that, while improving the problem of difficulty in cleaning, can also improve the inhalation experience of the aerosol-generating article by adjusting the suction resistance.

[0007] To achieve the above objectives, embodiments of this disclosure provide an aerosol generating article, comprising a pre-plug section and a matrix section.

[0008] The matrix segment is used to generate aerosols.

[0009] The anterior plug segment is located at the distal lip end of the matrix segment.

[0010] The front plug section includes multiple front plug parts, which are detachably coupled.

[0011] In one embodiment, the matrix segment is constructed by winding or aggregating an aerosol matrix sheet, the aerosol matrix sheet comprising a sheet-like matrix, the sheet-like matrix comprising a plurality of parallel matrix strips, at least one connecting region being formed between adjacent matrix strips, the connecting region connecting adjacent matrix strips, and the aerosol matrix sheet being heatable to generate aerosol.

[0012] In one embodiment, at least a portion of the front plug is arranged radially along the aerosol-generating article.

[0013] In one embodiment, at least a portion of the front plug is arranged along the axial direction of the aerosol-generating article.

[0014] In one embodiment, the plurality of front plug portions include an annular structure and a core portion, wherein the annular structure has a connecting channel extending through at least one end of the annular structure along the axial direction.

[0015] The core is detachably disposed within the connection channel.

[0016] In one embodiment, the connecting channel extends through both ends of the annular structure along the axial direction.

[0017] In one embodiment, one end of the core protrudes radially outward to form a flange, which is located at one end of the annular structure along the axial direction and is used to limit and cooperate with the end face of the annular structure.

[0018] In one embodiment, the annular structure includes at least two sub-rings arranged around the central axis of the annular structure.

[0019] In one embodiment, the core includes at least two sub-cores arranged around the central axis of the core.

[0020] In one embodiment, the equivalent aperture of the connecting channel is in the range of 1 mm to 3 mm, or the equivalent diameter of the core is in the range of 1 mm to 3 mm.

[0021] In one embodiment, the length of the matrix segment is in the range of 8 mm to 20 mm, and the total mass of the matrix segment is greater than or equal to 200 mg.

[0022] In one embodiment, the matrix strip includes an aerosol forming agent, the weight of which is in the range of 15% to 30% based on the dry weight of the matrix strip, and the density of the matrix strip is greater than or equal to 1000 mg / cm³. 3 And less than or equal to 1500 mg / cm 3 .

[0023] In one embodiment, the aerosol-generating article further includes a functional segment located near the lip end of the matrix segment.

[0024] The functional segment includes a hollow tube segment, the interior of which forms a hollow channel.

[0025] In one embodiment, the functional segment includes a filter segment disposed at the end of the hollow tube segment away from the matrix segment, the suction resistance of the functional segment is greater than the suction resistance of the forepump segment, and the suction resistance of the filter segment is greater than the suction resistance of the matrix segment.

[0026] This disclosure provides an aerosol generating product, including a pre-plug section and a matrix section. The matrix section is used to generate aerosols. By setting the pre-plug section at the distal lip end of the matrix section, the probability of the matrix section falling off can be reduced. The pre-plug section can block and adsorb aerosols during the backflow / reverse flow process, which helps to improve the problem of aerosol generation device being contaminated by aerosols and difficult to clean. It also helps to improve the problem of cross-contamination of flavors that may occur when sucking aerosol generating products of different flavors. By configuring the pre-stop section to include multiple pre-stop sections, and selectively detachably engaging these sections, the draw resistance of the pre-stop section can be adjusted. The draw resistance (air intake) of the pre-stop section can be synergistically designed based on the density of the matrix section and the content of the aerosol forming agent. This coupling of the matrix section and the pre-stop section ensures that the air intake dynamics of the aerosol-generating product are coupled with the thermal characteristics of the matrix section. In other words, it allows for a more balanced thermal-fluid field coupling in the aerosol-generating product. While balancing aerosol generation, it also reduces the temperature difference between the distal and proximal ends of the matrix section, ensuring controllable pressure drop and mitigating issues such as localized overheating and insufficient extraction. By synergistically designing the air intake of the pre-stop section with the matrix section, the atomization effect of the aerosol-generating product is improved, as well as the aerosol extraction effect and the inhalation experience. Furthermore, the pre-stop section can be adjusted according to different matrix sections to improve its adaptability, or it can be adjusted according to different user needs to enhance the adaptability of the aerosol-generating product. In addition, by selectively detachably fitting multiple front plug sections, different heating methods can be matched. For example, circumferential heating and center heating can each be matched with the corresponding front plug section structure. Attached Figure Description

[0046] The present disclosure will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0047] This disclosure provides an aerosol generating article 10. Referring to Figures 1 to 3, the aerosol generating article 10 includes a front plug section 12 and a matrix section 11. The matrix section 11 is used to generate aerosols. The front plug section 12 is located at the distal lip end of the matrix section 11. The front plug section 12 includes a plurality of front plug portions, which are detachably engaged.

[0048] In this embodiment of the disclosure, the aerosol generating article 10 is described as being suitable for suction by heating without combustion.

[0049] This disclosure also provides an aerosol generation system 100. Referring to FIG1, the aerosol generation system 100 includes an aerosol generation article 10 and an aerosol generation device 20 according to any embodiment of this disclosure.

[0050] 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.

[0051] Aerosol generating article 10 is used to generate aerosols when heated for users to inhale.

[0052] In this embodiment of the disclosure, the aerosol-generated article 10 is generally cylindrical. The cylindrical shape can be a cylinder (i.e., with a circular cross-section), a prism (i.e., with a polygonal cross-section), an elliptical cylinder (i.e., with an elliptical cross-section), etc., and is not limited thereto.

[0053] Here, the aerosol generating device 20 can contain one or more aerosol generating products 10.

[0054] In this disclosure, "multiple" refers to two or more items.

[0055] The proximal end refers to the end of the aerosol generating article 10 that is closer to the user when the user uses it, while the distal end refers to the end of the aerosol generating article 10 that is farther away from the user when the user uses it. In other words, the two ends of the aerosol generating article 10 along the first direction are the proximal end and the distal end, respectively.

[0056] For example, referring to Figures 2 and 3, the aerosol generating article 10 also includes a functional segment 13 located near the lip end of the matrix segment 11.

[0057] For example, functional segment 13 includes filter segment 132.

[0058] For example, the aerosol generated by the heated aerosol generating article 10 can flow through the filter section 132, which can filter out large particulate components and unwanted impurities in the aerosol. That is, the aerosol generated by the heated aerosol generating article 10 is filtered through the filter section 132 and then inhaled by the user.

[0059] For example, functional segment 13 includes hollow tube segment 131.

[0060] Hollow tube section 131 can cool down the aerosols flowing through it.

[0061] In an embodiment where functional segment 13 includes both filter segment 132 and hollow tube segment 131, hollow tube segment 131 is disposed between matrix segment 11 and filter segment 132.

[0062] For example, the aerosol generated by the heated aerosol generating article 10 can first flow through the hollow tube section 131 for cooling. After cooling, the aerosol then flows through the filter section 132, which can filter out large particles and unwanted impurities in the aerosol. That is, the aerosol generated by the heated aerosol generating article 10 is cooled and filtered sequentially through the hollow tube section 131 and the filter section 132 before being drawn in by the user.

[0063] For example, functional segment 13 includes support segment 133, which can support the aerosol-generated article 10. Of course, support segment 133 can also cool the flowing aerosol.

[0064] For example, please refer to Figure 3. The aerosol generating article 10 includes a front plug section 12, a matrix section 11, a hollow tube section 131 and a filter section 132 arranged in sequence.

[0065] For example, the aerosol generating article 10 also includes a coating layer 135, which wraps around the outer periphery of the fore plug section 12, the matrix section 11, the hollow tube section 131 and the filter section 132.

[0066] For example, the material of the wrapping layer 135 is one or more of paper, paper tube, tin foil, and aluminum foil.

[0067] For example, the wrapping layer 135 may be bottom-ventilated or bottom-sealed.

[0068] The front plug section 12 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 12 can effectively reduce the probability of the matrix section 11 falling out of the encapsulation layer 135; 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, thereby causing the receiving chamber 21 to be contaminated and difficult to clean, and preventing the problem of cross-contamination of flavors when sucking in different flavored aerosol generating products 10.

[0069] For example, the materials of the pre-plug section 12 include, but are not limited to, paper, non-woven fabric, rubber, polyethylene terephthalate, cellulose acetate, cellulose acetate propionate, high molecular weight polyester, mineral-containing products, cellulose paper filter rods, plant polysaccharides, etc.

[0070] Of course, in other embodiments, functional segment 13 may also include a suction resistance adjustment segment.

[0071] For example, functional section 13 includes a suction resistance adjustment section. The aerosol generated by heating the aerosol generating product 10 first flows through the suction resistance adjustment section, then flows through the hollow tube section 131 for cooling. After cooling, the aerosol flows through the filtration section 132, which can filter out large particles and unwanted impurities in the aerosol. That is, the aerosol generated by heating the aerosol generating product 10 passes through the suction resistance adjustment section, the hollow tube section 131, and the filtration section 132 in sequence for suction resistance adjustment, cooling, and filtration before being drawn in by the user.

[0072] For example, the front plug section 12 and / or the functional section 13 are cylindrical with a circular or elliptical cross-section. When the front plug section 12 and / or the functional section 13 includes multiple functional sections 13 with filtering and cooling effects, the longitudinal centers of the front plug section 12 and / or the functional section 13 are coaxially aligned.

[0073] For example, the material of the filter section 132 includes, but is not limited to, cellulose acetate, polyethylene terephthalate, polypropylene fiber, cellulose paper filter rod, recycled tobacco, polylactic acid fiber, resin, plant polysaccharides, etc. The filter section 132 can filter and adsorb aerosols, thereby improving the purity and comfort of aerosols.

[0074] For example, the material of the hollow tube section 131 includes, but is not limited to, cellulose acetate, cellulose acetate propionate, PLA (polylactic acid), PET (polyethylene terephthalate), etc.

[0075] For example, referring to FIG1, the aerosol generating apparatus 20 includes a heating element 22 for heating the aerosol generating article 10 to generate aerosol.

[0076] The heating element 22 can heat the substrate segment 11 in any way. Exemplarily, the heating methods include center heating and peripheral heating. Center heating refers to the heating element being inserted into the substrate segment 11 to bake and heat it from the inside out. Peripheral heating refers to the heating element being positioned around the substrate segment 11 to bake and heat it from the outside in. These heating methods can specifically be at least one of resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, etc., and are not specifically limited here.

[0077] Specifically, the aerosol generating device 20 includes a housing and a power supply component 23 disposed within the housing. The housing has a receiving chamber 21. The power output part of the power supply component 23 is disposed within the receiving chamber 21 or around the side wall of the receiving chamber 21. When the portion of the aerosol generating article 10 located in the first direction range is inserted into the receiving chamber 21, the power output part transmits electrical energy to the heating element 22 in a contact or non-contact manner. The heating element 22 receives energy from the outside and generates heat, thereby heating the aerosol generating article 10 and generating aerosol.

[0078] Please refer to Figures 4 to 10. The front plug section 12 includes multiple front plug parts, which are detachable and can be used together. In other words, the user can combine multiple front plug parts according to the application scenario. That is, the user can select the appropriate front plug parts for combination according to their needs or according to different matrix sections 11.

[0079] Exemplary, the specific manner in which the multiple front plugs can be detachably coupled is not limited here. For example, it can be one or more combinations such as two front plugs joined side by side, a central post and annular structure 121, or joined along the axial direction.

[0080] It should be noted that the specific composition of matrix segment 11 is not limited here.

[0081] For example, in some embodiments, the matrix segment 11 may include tobacco plants, etc.

[0082] In other embodiments, the raw materials for the matrix segment 11 include protein sources, fiber sources, adhesives, soluble inorganic salts, and inorganic fillers. Specifically, the protein sources include one or more of rice protein, wheat protein, soybean protein, and pea protein; the fiber sources include one or more of bamboo fiber, isatis root fiber, soybean fiber, pea fiber, rice bran fiber, broadleaf fiber, and microcrystalline cellulose; the particle size of the protein sources and fiber sources is 80-120 mesh. The adhesives include one or more of guar gum, xanthan gum, carrageenan, sodium polyacrylate, sodium carboxymethyl cellulose, locust gum, konjac gum, and gellan gum. A mixture of one or more of sodium chloride, potassium carbonate, and sodium carbonate, and a mixture of one or more of sodium dihydrogen phosphate, sodium pyrophosphate, and sodium metaphosphate are used as soluble inorganic salts; a mixture of one or more of light calcium carbonate, heavy calcium carbonate, and alumina is used as an inorganic filler, the particle size of which is 160-200 mesh.

[0083] For example, 8-14 parts of protein source, 20-45 parts of fiber source, 10-20 parts of inorganic filler, and 2-8 parts of adhesive are taken and thoroughly mixed. Separately, 25-35 parts of glycerol, 8-15 parts of propylene glycol, 25-30 parts of fragrance, and 2-5 parts of inorganic salt are dissolved in 10-15 parts of water. The liquid materials are thoroughly mixed, and then the liquid materials are added to the stirred solid materials in the form of a spray and thoroughly mixed to obtain a matrix slurry. The matrix slurry is extruded to obtain a primary sheet matrix 111 structure of the first thickness. The primary sheet matrix 111 structure is pressed into an aerosol matrix sheet of the second thickness, wherein the first thickness is greater than the second thickness. The aerosol matrix sheet is cut into multiple unbroken matrix strips 112. The cut aerosol matrix sheets are wound or aggregated.

[0084] This disclosure provides an aerosol generating article 10, including a pre-plug section 12 and a matrix section 11. The matrix section 11 is used to generate aerosols. By providing the pre-plug section 12 at the distal lip end of the matrix section 11, the probability of the matrix section 11 falling off can be reduced. Furthermore, the pre-plug section 12 can adsorb aerosols during the backflow / reverse flow process, which helps to improve the problem of aerosol contamination of the aerosol generating device 20 and its difficulty in cleaning. It also helps to improve the problem of cross-contamination of flavors that may occur when inhaling aerosol generating articles 10 with different flavors. By configuring the pre-stop section 12 to include multiple pre-stop portions, and selectively detachably engaging these portions, the draw resistance of the pre-stop section 12 can be adjusted. The draw resistance (air intake) of the pre-stop section 12 can be synergistically designed based on the density of the matrix section 11 and the content of the aerosol forming agent. This couples the matrix section 11 and the pre-stop section 12, coupling the air intake dynamics of the aerosol-generating product 10 with the thermal characteristics of the matrix section 11. In other words, the thermal-fluid field coupling of the aerosol-generating product 10 can be kept as balanced as possible. While balancing aerosol generation, this also reduces the temperature difference between the distal and proximal ends of the matrix section 11, making pressure drop controllable and improving local overheating and insufficient local extraction. By synergistically designing the air intake of the pre-stop section 12 with the matrix section 11, the atomization effect of the aerosol-generating product 10, as well as the aerosol extraction effect and the inhalation experience, are improved. Furthermore, the front plug section 12 can be adjusted according to different matrix sections 11 to improve the adaptability of the matrix section 11, or the front plug section 12 can be adjusted according to different user needs to improve the adaptability of the aerosol-generated product 10. In addition, different heating methods can be matched and adapted according to different combinations of the front plug section, such as peripheral heating and center heating.

[0085] For example, please refer to Figures 1 to 3, where the foreplug section 12 and the matrix section 11 are arranged along a first direction.

[0086] The pre-plug segment 12 is located at the distal lip end of the matrix segment 11, and the interior of the pre-plug segment 12 has a connecting channel 1211 that passes through at least one end of the pre-plug segment 12 along a first direction. In some embodiments, referring to Figures 11 and 12, the matrix segment 11 is configured to be formed by winding or agglomerating an aerosol matrix sheet.

[0087] In some embodiments, please refer to Figures 11 and 12. The aerosol matrix sheet includes a sheet matrix 111, which is an integral structure. The sheet matrix 111 includes a plurality of parallel matrix strips 112. At least one connecting region 113 is formed between adjacent matrix strips 112. The connecting region 113 connects adjacent matrix strips 112. The aerosol matrix sheet can be heated to generate aerosol.

[0088] The sheet matrix 111 has an integral structure, which is beneficial to improving the integrity of the sheet matrix 111 and thus improving its stability.

[0089] Please refer to Figures 11 and 12. The formation of at least one connection region 113 between adjacent matrix strips 112 means that there may be one connection region 113 between adjacent matrix strips 112, or multiple connection regions 113 may be formed, or a portion of the matrix strips 112 may have one connection region 113 between them, while another portion of the matrix strips 112 may have multiple connection regions 113 between them.

[0090] Here, the connecting regions 113 formed between the matrix strips 112 can be the same or different.

[0091] It should be noted that the specific location of the connecting area 113 is not restricted here.

[0092] In an embodiment where a connecting region 113 is formed between adjacent matrix strips 112, the connecting region 113 may be formed at the end, middle, or between the end and middle of the matrix strip 112; in an embodiment where multiple connecting regions 113 are formed between adjacent matrix strips 112, the multiple connecting regions 113 may be uniformly distributed or not uniformly distributed. For example, the sheet matrix 111 is cut into multiple matrix strips 112 by pressing or rolling with a cutter or a die, but at least some of the adjacent matrix strips 112 are not cut, that is, there will still be connecting regions 113 connecting the adjacent matrix strips 112.

[0093] In some embodiments, a connecting region 113 is included between adjacent matrix strips 112, and the connecting region 113 completely covers the area between adjacent matrix strips 112. That is, adjacent matrix strips 112 are connected by a connecting region 113, and there is no disconnection between adjacent matrix strips 112. For example, the matrix strip 112 is formed by a portion of the surface of an aerosol matrix sheet protruding outward, with depressions formed between adjacent protrusions, and at least a portion of the depressions constitutes the connecting region 113. The sheet-like matrix 111 is pressed using a mold or roller, so that multiple protruding strips, i.e., matrix strips 112, are formed on at least one side of the sheet-like matrix 111, as shown in FIG11. A groove is formed between adjacent matrix strips 112, and the bottom area of ​​the groove constitutes the connecting region 113. Of course, it is understood that the grooves formed by pressing may also be discontinuous in some embodiments.

[0094] For example, adjacent matrix strips 112 are connected by a connecting region 113, the two ends of which extend to the two ends of the extending direction of the matrix strip 112. The dimension of the connecting region 113 in the thickness direction of the aerosol matrix sheet is smaller than the maximum dimension of the matrix strip 112 in the thickness direction of the aerosol matrix sheet. For example, the thickness of the bottom wall of the groove is smaller than the maximum dimension of the matrix strip 112 in the same direction as the bottom wall thickness.

[0095] In other embodiments, adjacent matrix strips 112 include a plurality of spaced-apart connecting regions 113, which cover a portion of the area between adjacent matrix strips 112, while other areas between adjacent matrix strips 112 are disconnected. That is, adjacent matrix strips 112 are connected by a plurality of connecting regions 113, and other areas between adjacent matrix strips 112 are disconnected.

[0096] In related technologies, aerosol matrix segments are obtained by bundling together multiple independent matrix strips. However, the integrity of multiple independent matrix strips is poor, the structural strength is low, and it is not conducive to assembly and manufacturing. During packaging, handling, transportation, or suction, the matrix strip 112 may break and fall off.

[0097] In this embodiment of the present disclosure, adjacent matrix strips 112 can be connected together through the connecting area 113, which is beneficial to improve the integrity and overall strength of the sheet matrix 111, can improve the situation of matrix strips 112 breaking and falling off, and is beneficial to improve smoke volume, suction stability and yield.

[0098] In related technologies, the matrix units of the aerosol matrix segment are mainly in the form of flakes, filaments, and granules. In related technologies where the matrix units are granular, the filling process for filling the matrix units results in unstable suction resistance. Furthermore, the vibration and other effects during transportation and storage of granular matrix units can cause the granular matrix units in local areas of the aerosol matrix segment to become increasingly compact, leading to greater suction resistance and a poor suction experience.

[0099] The aerosol matrix sheet of this embodiment is formed by cutting the sheet-like matrix 111 into multiple matrix strips 112. This allows for the formation of stable air channels between adjacent matrix strips 112 after the aerosol matrix sheet is wound to form matrix segments 11, thereby improving the stability of the draw resistance. Furthermore, the draw resistance of the matrix segments 11 can be adjusted by regulating the density, porosity, and size of the matrix strips 112. Additionally, by forming at least one connecting region 113 between adjacent matrix strips 112, the integrity and overall strength of the sheet-like matrix 111 are improved. This helps reduce displacement and breakage caused by vibration, bending, pressure, etc., during transportation, storage, or use, further enhancing the stability of the draw resistance. It also reduces the likelihood of matrix strips 112 breaking and detaching, thus improving smoke volume, draw stability, and yield. Moreover, the matrix strips 112 are a homogeneous system, which facilitates the continuous and uniform generation of aerosols.

[0100] Matrix strip 112 includes an aerosol forming agent, the weight of which ranges from 15% to 30% based on the dry weight of matrix strip 112. The density of matrix strip 112 is 1000 mg / cm³. 3 Up to 1500 mg / cm 3 The range.

[0101] The weight of the aerosol forming agent can be any one of 15%, 16%, 17%, 18%, 20%, 22%, 23%, 25%, 26%, 27%, 28%, or 30%, or any combination thereof.

[0102] Aerosol forming agents are used to form aerosols.

[0103] Because the aerosol forming agent is highly hydrophilic, on the one hand, the drying process of the matrix strip 112 will affect the removal of moisture, requiring a greater drying intensity, and excessive drying intensity may lead to greater loss of the corresponding aroma components; on the other hand, during the storage of the aerosol-generated product 10, the aerosol forming agent will absorb moisture, which may lead to an increase in the moisture content of the matrix strip 112.

[0104] In this embodiment, based on the dry weight of the matrix strip 112, by setting the weight of the aerosol forming agent to a range of 15% to 30%, the matrix strip 112 can generate a certain amount of aerosol and have a certain amount of smoke, while reducing the water retention and moisture absorption capacity of the aerosol, thereby improving the situation where the high moisture content of the matrix strip 112 leads to a large loss of aroma during the drying process.

[0105] The density of aerosol matrix tablets can be 1000 mg / cm³. 31050mg / cm 3 1080mg / cm 3 1100mg / cm 3 1150mg / cm 3 1180mg / cm 3 1200mg / cm 3 1250mg / cm 3 1260mg / cm 3 1280mg / cm 3 1300mg / cm 3 1350mg / cm 3 1360mg / cm 3 1380mg / cm 3 1400mg / cm 3 1450mg / cm 3 1480mg / cm 3 1500mg / cm 3 The point value of any one of them or the point value between any two.

[0106] Here, when the density of the aerosol matrix sheet is greater than 1500 mg / cm³ 3 At this time, the absorption resistance of matrix segment 11 may be relatively large, resulting in a smaller amount of smoke, which greatly limits the generation and migration of aerosols. When the density of the aerosol matrix sheet is less than 1000 mg / cm³, 3 At times, this may result in insufficient stiffness of the matrix segment 11, a smaller amount of smoke, poor consistency of the matrix segment 11, and low vaping satisfaction.

[0107] Thus, by setting the density of the aerosol matrix tablet to be greater than or equal to 1000 mg / cm³ 3 And less than or equal to 1500 mg / cm 3 This allows the substrate segment 11 to have appropriate draw resistance, as well as a certain degree of stiffness and smoke volume, which helps to improve the consistency of the substrate segment 11 and the satisfaction of vaping.

[0108] In some embodiments, the thickness of at least a portion of the connecting region 113 is less than the maximum dimension of the matrix strip 112 along the thickness direction of the aerosol matrix sheet.

[0109] Here, the thickness of all the connecting regions 113 may be less than the maximum dimension of the matrix strip 112 along the thickness direction of the aerosol matrix sheet, or the thickness of some of the connecting regions 113 may be less than the maximum dimension of the matrix strip 112 along the thickness direction of the aerosol matrix sheet, while the thickness of another part of the connecting regions 113 may be equal to the maximum dimension of the matrix strip 112 along the thickness direction of the aerosol matrix sheet.

[0110] In this embodiment, by making the thickness of at least part of the connecting region 113 less than the maximum dimension of the matrix strip 112 along the thickness direction of the aerosol matrix sheet, a stable air passage can be formed at the connecting region 113 after the aerosol matrix sheet is wound to form the matrix segment 11, and the strength of the connecting region 113 can also be strengthened, thereby improving the stability of the suction resistance and the integrity of the aerosol matrix sheet.

[0111] In some embodiments, the substrate strip 112 is constructed by pressing and cutting a sheet-like substrate 111, with a groove formed between adjacent substrate strips 112, and a portion of the bottom wall of the groove forming a connecting region 113.

[0112] For example, the sheet substrate 111 can be cut or pressed by a mold to form an uneven surface on the sheet substrate 111. Here, the protruding area is the substrate strip 112 and the recessed area is the groove.

[0113] For example, the matrix strip 112 extends along a first direction.

[0114] In some embodiments, the cutting direction of the sheet-like matrix 111 includes a second direction.

[0115] Here, the continuous lines or dashed lines inside the sheet-like matrix 111 in Figure 12 represent the cutting lines of the sheet-like matrix 111, and the breaks in the dashed lines represent the connecting regions 113.

[0116] Here, the sheet-like matrix 111 can be cut only along the second direction, or it can be cut along other directions in addition to the second direction.

[0117] In some embodiments, as shown in Figure 11, the first direction is parallel to the second direction.

[0118] In other words, the extension direction of the matrix strip 112 is parallel to the cutting direction of the sheet matrix 111.

[0119] Here, the extension direction of the matrix strip 112 and the cutting direction of the sheet matrix 111 can be approximately parallel or completely parallel.

[0120] In some embodiments, as shown in Figure 12, the first direction intersects with the second direction.

[0121] Here, the extension direction of the matrix strip 112 intersects the cutting direction of the sheet matrix 111. That is, the extension direction of the matrix strip 112 is not parallel to the cutting direction of the sheet matrix 111. For example, the extension direction of the matrix strip 112 is perpendicular to the cutting direction of the sheet matrix 111.

[0122] Of course, in other embodiments, the sheet-like matrix 111 includes multiple cutting directions. For example, the sheet-like matrix 111 includes a cutting direction parallel to the extension direction of the matrix strip 112, and also includes a cutting direction intersecting the extension direction of the matrix strip 112.

[0123] In some embodiments, as shown in Figures 3 and 4, the extension trajectory of the groove is a straight line or a curve.

[0124] In other words, the shearing direction of the sheet-like matrix 111 can be curved, such as S-shaped, spiral, etc., or it can be straight.

[0125] In some embodiments, the tensile strength of the sheet matrix 111 along the length of the matrix strip 112 is greater than or equal to 300 N / m.

[0126] Tensile strength, also known as tensile strength or breaking strength, represents the breaking force per unit area.

[0127] Tensile strength is the maximum load that causes the sheet matrix 111 test piece to break from its original cross-section.

[0128] The measurement standard can be a horizontal tensile strength measuring instrument, with a test sample width of 15 mm and the thickness can be modified according to the actual thickness of the sample.

[0129] Here, by setting the tensile strength of the sheet-like matrix 111 along the length of the matrix strip 112 to be greater than or equal to 300 N / m, the breakage and detachment of the matrix strip 112 can be improved, which is beneficial to increasing the amount of smoke, the suction stability, and the yield. In addition, the matrix segment 11 can be made into a homogeneous system, which is conducive to the continuous and uniform generation of aerosols.

[0130] It should be noted that there are no restrictions on the arrangement of the various front plugs.

[0131] In some embodiments, as shown in Figures 4 to 6, at least a portion of the front plug is arranged radially along the aerosol generating article 10.

[0132] The entire front plug portion can be arranged radially along the aerosol generating article 10, or only a portion of the front plug portion can be arranged radially along the aerosol generating article 10.

[0133] For example, multiple front plugs may be arranged sequentially along the radial direction of the aerosol generating article 10. The internal front plugs may be removed or assembled as needed to adjust the suction resistance of the front plug section 12. In addition, some front plugs may be removed as needed to adjust the air intake section.

[0134] For example, an air passage can be formed between adjacent front plugs, through which external air can enter.

[0135] In some embodiments, referring to Figures 4 to 6, a plurality of front plug portions include an annular structure 121 and a core 122. The annular structure 121 has a connecting channel 1211 inside, the connecting channel 1211 extending through at least one end of the annular structure 121 along the axial direction, and the core 122 is detachably disposed within the connecting channel 1211.

[0136] For example, the core 122 may be columnar.

[0137] For example, the ring structure 121 and the core 122 can be regular cylinders or irregular shapes, as long as they can form an interlocking or spliced ​​structure.

[0138] For example, before the aerosol generating article 10 is inserted into the aerosol generating device 20, the core 122 is removed first, and the connecting channel 1211 can cooperate with the heating element, that is, the heating element can be inserted into the connecting channel 1211 to achieve central heating of the aerosol generating article 10.

[0139] For example, the connection channel 1211 extends along the axial direction of the aerosol generating article 10.

[0140] For example, if the fore plug segment 12 and the matrix segment 11 are arranged along a first direction, then the connecting channel 1211 extends along the first direction.

[0141] The connection channel 1211 passing through at least one end of the front plug section 12 along the first direction means that the connection channel 1211 can pass through one end of the front plug section 12 along the first direction, or it can pass through both ends of the front plug section 12 along the first direction, that is, the connection channel 1211 passes through both ends of the annular structure 121 along the axial direction.

[0142] For example, the centerline of the connecting channel 1211 may coincide with the centerline of the front plug section 12, or it may be parallel but not coincident.

[0143] The number of connection channels 1211 can be one or more.

[0144] The interior of the front plug section 12 has a connecting channel 1211, which allows external air to enter the matrix section 11 through the connecting channel 1211, supplying oxygen for the atomization of the matrix section 11 and extracting and cooling the generated aerosol. At the same time, it can also be used to set the core 122, thereby adjusting the suction resistance of the front plug section 12.

[0145] By configuring multiple front plug sections including an annular structure 121 and a core 122, the core 122 can be selectively and detachably disposed within the connecting channel 1211 to adjust the suction resistance of the front plug section 12. Furthermore, the core 122 can be removed from the connecting channel 1211 and, through the cooperation of a heating element with the connecting channel 1211, to achieve central heating of the aerosol generating article 10. In other words, the aerosol generating article 10 can be simultaneously subjected to peripheral heating and central heating; however, when using central heating, the user needs to remove the core 122.

[0146] In some embodiments, as shown in Figures 7 and 8, one end of the core 122 protrudes radially outward to form a flange 1222, which is located at one end of the annular structure 121 along the axial direction and is used to limit and cooperate with the end face of the annular structure 121.

[0147] Here, the core 122 may be an axially protruding end forming a flange 1222.

[0148] For example, in some embodiments, the outer diameter of the flange 1222 is the same as the outer diameter of the annular structure 121. In other embodiments, the outer diameter of the flange 1222 may be smaller than the outer diameter of the annular structure 121.

[0149] For example, the outer diameter of the flange 1222 is larger than the equivalent diameter of the connecting channel 1211, which allows the flange 1222 to abut against the end face of the annular structure 121, that is, the flange 1222 and the annular structure 121 are in a limiting fit, thereby improving the connection reliability between the annular structure 121 and the core 122.

[0150] In this embodiment, the core 122 is provided with a flange 1222. When the core 122 is disposed within the connecting channel 1211, the flange 1222 is located at one end of the annular structure 121 along the axial direction, and is used to limit and cooperate with the end face of the annular structure 121, thereby improving the connection reliability between the annular structure 121 and the core 122, and also making it easier for the user to disassemble. It should be noted that the flange 1222 can be disposed away from the substrate segment 11. In this case, the core with the flange 1222 can be removed for matching center heating or matching peripheral heating. When the flange 1222 is connected to the substrate segment, the user can remove the annular structure 121 for matching peripheral heating.

[0151] For example, the core 122 can be a single unit.

[0152] Of course, as shown in Figures 9 and 10, the core 122 may also include at least two sub-cores 1221.

[0153] For example, at least a portion of the sub-cores 1221 are arranged along the axial direction of the aerosol-generating article 10.

[0154] Here, the axial direction of the aerosol-generated product 10 is the first direction.

[0155] All of the sub-cores 1221 can be arranged along the axial direction of the aerosol-generating product 10, or only some of the sub-cores 1221 can be arranged along the axial direction of the aerosol-generating product 10.

[0156] For example, the sub-cores 1221 arranged along the axial direction of the aerosol generating article 10 are all disposed within the connecting channel 1211 of the annular structure 121.

[0157] It is understandable that the more sub-cores 1221 arranged along the axial direction of the aerosol generating product 10, the greater the suction resistance adjustment range of the corresponding front plug section 12.

[0158] In this embodiment, by arranging at least a portion of the sub-cores 1221 along the axial direction of the aerosol-generating article 10, the number of sub-cores 1221 can be selectively increased or decreased to adjust the suction resistance of the front plug section 12.

[0159] For example, at least a portion of the sub-core 1221 is arranged around the first axis, wherein the arrangement direction of the front plug section 12 and the matrix section 11 is parallel to the first axis.

[0160] For example, the first axis may be the central axis of the aerosol generating article 10. That is, the core 122 includes at least two sub-cores 1221, which are arranged around the central axis of the core 122.

[0161] By arranging the sub-core 1221 around the central axis of the core 122, the suction resistance of the front plug section 12 can be adjusted, and the intake area of ​​the front plug section 12 can be selected according to the needs.

[0162] In one specific embodiment, please refer to Figures 9 and 10. The core 122 includes two symmetrically distributed sub-cores 1221, which are spliced ​​together to form the core 122.

[0163] In this embodiment, a portion of the sub-core 1221 can be removed as needed to adjust the air intake section.

[0164] In some embodiments, some of the sub-cores 1221 may be arranged along the axial direction of the aerosol generating article 10, and some of the sub-cores 1221 may be arranged around the first axis.

[0165] In some embodiments, as shown in Figures 9 to 10, the annular structure 121 includes at least two sub-rings 1212, which are arranged around the central axis of the annular structure 121.

[0166] All the sub-rings 1212 are sequentially spliced ​​to form a ring structure 121, and a connecting channel 1211 is formed around it.

[0167] By configuring the annular structure 121 to include at least two sub-rings 1212, and arranging the sub-rings 1212 around the central axis of the annular structure 121, the intake resistance of the front piston section 12 can be adjusted, and the intake area of ​​the front piston section 12 can be selected as needed.

[0168] In some embodiments, the equivalent aperture of the connecting channel 1211 is in the range of 1 mm to 3 mm, or the equivalent diameter of the core 122 is in the range of 1 mm to 3 mm.

[0169] The equivalent aperture of the connecting channel 1211 can be any one of 1mm, 1.3mm, 1.5mm, 1.7mm, 1.8mm, 2mm, 2.2mm, 2.5mm, 2.6mm, 2.8mm, or 3mm, or any value between two of them.

[0170] The equivalent diameter of the core 122 can be any one of 1mm, 1.3mm, 1.5mm, 1.7mm, 1.8mm, 2mm, 2.2mm, 2.5mm, 2.6mm, 2.8mm, or 3mm, or any value between two of them.

[0171] This facilitates the fitting of the heating element with the connecting channel 1211. In addition, air can be introduced through the connecting channel 1211 within this size range so that the suction resistance of the front plug section 12 is appropriate.

[0172] In some embodiments, at least a portion of the front plug is arranged along the axial direction of the aerosol generating article 10.

[0173] The entire front plug portion can be arranged along the axial direction of the aerosol generating product 10, or only a portion of the front plug portion can be arranged along the axial direction of the aerosol generating product 10.

[0174] In this embodiment, by arranging at least a portion of the front plug along the axial direction of the aerosol generating article 10, the number of front plugs can be selectively increased or decreased to adjust the suction resistance of the front plug section 12.

[0175] In some embodiments, at least a portion of the front plug portion is arranged around the second axis, wherein the arrangement direction of the front plug segment 12 and the matrix segment 11 is parallel to the second axis.

[0176] For example, the second axis may be the central axis of the aerosol-generating article 10.

[0177] In this embodiment, part of the front plug can be removed as needed to adjust the air intake section.

[0178] In some embodiments, a portion of the front plug may be arranged along the axial direction of the aerosol generating article 10, and a portion of the front plug may be arranged around the second axis.

[0179] In some embodiments, the porosity of the foreplug section 12 is greater than or equal to 18%.

[0180] In this way, external air can smoothly enter the matrix section 11 through the front plug section 12, which is conducive to the uniform and stable release of aerosols, and also makes the suction resistance of the front plug section 12 appropriate.

[0181] For example, please refer to Figures 2 and 3. A hollow channel 1311 is formed inside the hollow tube section 131, and the hollow channel 1311 extends along a first direction.

[0182] The hollow tube section 131 forms a hollow channel 1311 inside, which is beneficial for the aerosol generated by the heating matrix section 11 to flow through the hollow channel 1311 for cooling. After passing through the hollow channel 1311, the aerosol flows through the filter section 132, which filters the aerosol.

[0183] The porosity of the hollow tube section 131 is less than that of the fore-plug section 12. This allows the suction resistance of the hollow tube section 131 to be relatively greater than that of the fore-plug section 12, thus enabling the air intake of the fore-plug section 12 to smoothly enter the matrix section 11, which facilitates the uniform and stable release of aerosols and makes aerosol extraction easier.

[0184] The length of the hollow tube segment 131 is greater than or equal to 15 mm and less than or equal to 20 mm. For example, the length of the hollow tube segment 131 can be any one of 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, and 20 mm, or any value between two of them.

[0185] The length of the hollow tube section 131 within this range can balance the cooling effect and reduce the condensation and retention of aerosols in the hollow tube section 131, thereby improving the aerosol extraction effect.

[0186] The equivalent aperture of the hollow channel 1311 is set to be greater than or equal to 1 mm and less than or equal to 3 mm. For example, the equivalent aperture of the hollow channel 1311 can be a point value of any one of 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, and 3 mm, or a point value between any two.

[0187] The equivalent aperture of the hollow channel 1311 is the inner diameter of the hollow channel 1311.

[0188] The inner diameter of the hollow channel 1311 can affect the fluid flow state, while the Reynolds number (Re) is a dimensionless parameter used in fluid mechanics to describe the characteristics of fluid flow. Its core significance lies in quantifying the relative strength of inertial force and viscous force, thereby determining the fluid flow state (laminar or turbulent).

[0189] When Re < 2000, viscous forces dominate, and the fluid flow tends to be laminar; when Re > 2000, inertial forces dominate, and the fluid flow may change to turbulent flow.

[0190] The Nusselt number (Nu) is a dimensionless criterion number in heat transfer that characterizes the intensity of convective heat transfer in a fluid. It is defined as the ratio of the convective heat transfer coefficient to the pure conductive heat transfer coefficient.

[0191] At lower Reynolds numbers, laminar flow is generally dominant; at higher Reynolds numbers, flow tends towards turbulence. Turbulence is caused by differences between local fluid velocities and flow directions. These local velocities and directions may intersect or even be opposite, thus forming eddies.

[0192] Therefore, if the inner diameter of the hollow channel 1311 is too large, the aerosol flow will be laminar (Reynolds number Re less than 2000), and the heat exchange rate with the cooling wall will be low (Nusser number Nu less than or equal to 5). The measured cooling efficiency (temperature drop rate) is only 15℃ / cm–20℃ / cm, which may lead to the aerosol outlet temperature exceeding the standard, affecting the sucking experience. In addition, if the inner diameter of the hollow channel 1311 is too large, the fluid flow speed will be slow, and slow cooling will cause volatile components (such as glycerol and propylene glycol) to condense on the inner wall of the hollow channel 1311 (loss rate greater than or equal to 25%), reducing the density of effective aerosols. Furthermore, it will prolong the residence time of high-temperature aerosols and synergistically exacerbate the formation of harmful substances. Therefore, by setting the equivalent aperture of the hollow channel 1311 to be greater than or equal to 1 mm and less than or equal to 3 mm, the aerosol flow can be made to be turbulent (Reynolds number Re greater than 3000) and have a high heat exchange rate with the cooling wall (Nuser number Nu greater than or equal to 12).

[0193] For example, the equivalent aperture of the hollow channel 1311 is smaller than the equivalent inner diameter of the connecting channel 1211.

[0194] In other words, the suction resistance of the hollow tube section 131 is greater than that of the front plug section 12. This allows the air intake of the front plug section 12 to smoothly enter the matrix section 11, thereby facilitating the uniform and stable release of aerosols and making it easier to extract aerosols.

[0195] The aerosol generating article 10 provided in this embodiment includes a functional segment 13 and a matrix segment 11 arranged sequentially. The matrix segment 11 is used to generate aerosols. By configuring the functional segment 13 to include a filter segment 132 and a hollow tube segment 131, with the hollow tube segment 131 located between the matrix segment 11 and the filter segment 132, the functional segment 13 can not only adjust the suction resistance of the aerosol generating article 10, but also cool and support the matrix segment 11 through the hollow tube segment 131, and filter the generated aerosols through the filter segment 132, thereby improving the suction experience. By setting the length of the hollow tube segment 131 to be greater than or equal to 15 mm and less than or equal to 20 mm, the cooling effect and the reduction of aerosol condensation and retention in the hollow tube segment 131 can be balanced, thereby improving the aerosol extraction effect. By setting the equivalent aperture of the hollow channel 1311 to be greater than or equal to 1 mm and less than or equal to 3 mm, the flow state of the aerosol can be made turbulent, which is beneficial to improving the cooling efficiency of the aerosol and reducing the proportion of air in the gas to correspondingly increase the proportion of aerosol, thereby increasing the aerosol concentration and enhancing the fullness and richness of the inhalation. In addition, the aperture within this range can take into account the nucleation and agglomeration of aerosols and have appropriate suction resistance, while allowing the gas to have a faster airflow velocity in the hollow channel 1311, enhancing the impact of aerosols during inhalation, improving the throat hit, reducing aerosol retention, and thus improving the inhalation experience. In other words, the aerosol generating article 10 of this embodiment, by setting the length of the hollow tube segment 131 to be greater than or equal to 15 mm and less than or equal to 20 mm, and setting the equivalent aperture of the hollow channel 1311 to be greater than or equal to 1 mm and less than or equal to 3 mm, can balance the cooling effect, aerosol nucleation and agglomeration, have suitable suction resistance, and enable the gas to have a faster airflow velocity in the hollow channel 1311, thereby enhancing the impact force of aerosol during suction, improving the throat hit sensation, reducing aerosol retention, and thus improving the aerosol extraction effect and suction taste.

[0196] For example, the aerosol generating article 10 has a suction resistance greater than or equal to 20 mm water column and less than or equal to 50 mm water column.

[0197] For example, the absorption resistance of the matrix segment 11 is greater than 0 and less than or equal to 5 mm of water column.

[0198] For example, the absorption resistance of the matrix segment 11 and the aerosol-generating article 10 can be tested according to GB / T 22838.5-2024.

[0199] The unit of suction resistance can be millimeters of water column (mmH2O).

[0200] For example, the absorption resistance of the matrix segment 11 can be any one of 0.01 mmH2O, 0.05 mmH2O, 0.1 mmH2O, 0.5 mmH2O, 1 mmH2O, 1.2 mmH2O, 1.5 mmH2O, 2 mmH2O, 2.2 mmH2O, 2.5 mmH2O, 3 mmH2O, 3.3 mmH2O, 3.5 mmH2O, 3.8 mmH2O, 4 mmH2O, 4.5 mmH2O, 4.8 mmH2O, 5 mmH2O, or a value between any two.

[0201] By setting the suction resistance of the matrix section 11 to be greater than 0 and less than or equal to 5 mm water column, the air intake of the front plug section 12 can smoothly enter the matrix section 11, which is conducive to the uniform and stable release of aerosols.

[0202] For example, the absorption resistance of the aerosol generating article 10 can be any one of 20 mmH2O, 23 mmH2O, 25 mmH2O, 28 mmH2O, 30 mmH2O, 33 mmH2O, 35 mmH2O, 38 mmH2O, 40 mmH2O, 42 mmH2O, 45 mmH2O, 48 mmH2O, or 50 mmH2O, or a value between any two.

[0203] Here, the absorption resistance of the matrix segment 11 constitutes part of the absorption resistance of the aerosol-generating article 10.

[0204] This disclosure provides an aerosol generating article 10, including a front plug section 12, a matrix section 11, and a functional section 13 arranged sequentially. The matrix section 11 is used to generate aerosols. By setting the front plug section 12 and the functional section 13 such that the front plug section 12 is located at the distal lip end of the matrix section 11, and the functional section 13 is located at the proximal lip end of the matrix section 11, that is, the front plug section 12 and the functional section 13 are respectively set at both ends of the matrix section 11 along the axial direction, which can reduce the probability of the matrix section 11 falling out of the aerosol generating article 10, and can perform functions such as suction resistance adjustment, cooling, support, or filtration on the aerosol generating article 10. By setting the suction resistance of the matrix section 11 to be greater than 0 and less than or equal to 5 mm water column, the appropriate suction resistance of the matrix section 11 within this range is conducive to the uniform generation of aerosols in the matrix section 11. It provides the necessary gaps required for the generation of aerosols in the matrix section 11, which can reduce the situation of aerosol output jamming or unstable output, so as to achieve uniform and stable release of aerosols, and also allows the air intake of the front plug section 12 to smoothly enter the matrix section 11. Meanwhile, by setting the suction resistance of the aerosol generating product 10 to be greater than or equal to 20 mm water column, it is beneficial for the aerosol generated in the matrix section 11 to be carried out. By setting the suction resistance of the aerosol generating product 10 to be less than or equal to 50 mm water column, it is beneficial to reduce the user's suction force, making suction easier, more natural and smoother, reducing suction fatigue, and making it easier for the user to maintain continuous suction. This can further reduce the situation of aerosol output jamming or unstable output, so as to achieve uniform and stable release of aerosol. Moreover, the suction resistance of the aerosol generating product 10 within this range can make the aerosol burst high and the aerosol volume large, improving the suction taste and user comfort.

[0205] In some embodiments, the suction resistance of the functional segment 13 is greater than that of the pre-plug segment 12, and the suction resistance of the filter segment 132 is greater than that of the matrix segment 11.

[0206] The pre-plug section 12 is located at the distal lip end of the matrix section 11, that is, the pre-plug section 12 is equivalent to the main air inlet end of the aerosol generation product 10. Therefore, by setting the suction resistance of the pre-plug section 12 to be less than that of the functional section 13, it is beneficial to increase the air intake of the aerosol generation product 10, thereby facilitating the generation and extraction of aerosols.

[0207] By setting the suction resistance of the matrix section 11 to be less than that of the filter section 132, the air intake of the front plug section 12 can smoothly enter the matrix section 11, which is conducive to the uniform and stable release of aerosols.

[0208] In this embodiment, by setting the suction resistance of the functional section 13 to be greater than that of the pre-stop section 12, and the suction resistance of the filter section 132 to be greater than that of the matrix section 11, it is beneficial to increase the air intake of the aerosol generating product 10, so that the air intake of the pre-stop section 12 can smoothly enter the matrix section 11, thereby facilitating the uniform and stable release of aerosols. The suction resistance of the functional section 13 is relatively larger than that of the pre-stop section 12 and the matrix section 11, which facilitates the extraction of aerosols.

[0209] In some embodiments, the suction resistance of the matrix segment 11 is less than or equal to the suction resistance of the foreplug segment 12.

[0210] It is understandable that by setting the suction resistance of the matrix section 11 to be less than or equal to that of the pre-stop section 12, it is beneficial to increase the contact area between the matrix section 11 and the gas, thereby facilitating the generation and release of aerosols. On the other hand, if the suction resistance of the pre-stop section 12 is greater than or equal to that of the matrix section 11, it can reduce the outflow of aerosols generated by the matrix section 11 from the pre-stop section 12 to a certain extent, thereby facilitating the extraction of aerosols and improving the utilization rate of aerosols.

[0211] In some embodiments, the length of the matrix segment 11 is in the range of 8 mm to 20 mm, and the total mass of the matrix segment 11 is greater than or equal to 200 mg.

[0212] The length of the matrix segment 11 can be any one of 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, or 20mm, or any combination thereof.

[0213] The longer the matrix segment 11 is, the more effective substances (aerosol forming agents) it contains, and the greater the amount of smoke. The shorter the matrix segment 11 is, the more it is beneficial to improve the ease of use and production efficiency of the matrix segment 11. In addition, it can also reduce the possibility of matrix strip 112 breaking.

[0214] In this embodiment, by setting the total mass of the matrix segment 11 to be greater than or equal to 200mg and setting the length of the matrix segment 11 to be between 8mm and 20mm, the matrix segment 11 has sufficient smoke volume, while also improving the ease of use and production efficiency of the matrix segment 11.

[0215] In some embodiments, the mass of the matrix segment 11 is greater than or equal to 400 mg, and the ratio of the mass of the matrix segment 11 to the mass of the functional segment 13 is greater than or equal to 1.5.

[0216] In this way, under the condition that the mass of the aerosol generating product 10 is constant, the aerosol generating product 10 can have a matrix segment 11 of a certain mass, thereby having a certain amount of smoke, which is conducive to improving the smoking satisfaction.

[0217] In some embodiments, the equivalent diameter of the matrix strip 112 is in the range of 0.5 mm to 2.5 mm.

[0218] The equivalent diameter of the matrix strip 112 can be any one of 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.2mm, 1.3mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.2mm, 2.3mm, or 2.5mm, or a value between any two of them.

[0219] The equivalent diameter is the diameter calculated by equating an irregular object to a sphere or circle with the same specific properties.

[0220] Here, with a fixed equivalent diameter of matrix segment 11, the larger the equivalent diameter of matrix strip 112, the greater the structural strength of matrix strip 112, which can reduce the possibility of matrix strip 112 breaking and reduce the processing difficulty; while the smaller the equivalent diameter of matrix strip 112, the more matrix strips 112 there are, which further helps to form a stable air passage between adjacent matrix strips 112, thereby improving the stability of suction resistance.

[0221] By setting the equivalent diameter of the matrix strip 112 to the range of 0.5 mm to 2.5 mm, the possibility of matrix strip 112 breaking can be reduced, the processing difficulty can be decreased, and it can further facilitate the formation of stable air passages between adjacent matrix strips 112, thereby improving the stability of suction resistance.

[0222] In some embodiments, the fill rate of the matrix segment 11 is greater than or equal to 65%.

[0223] In other words, on a cross section perpendicular to the extension direction of the matrix segment 11, the ratio of the sum of the cross-sectional areas of all matrix strips 112 in the matrix segment 11 to the cross-sectional area of ​​the matrix segment 11 is greater than or equal to 65%.

[0224] By setting the filling rate of the matrix segment 11 to be greater than or equal to 65%, the matrix segment 11 can have a certain amount of smoke, which is beneficial to improving the smoking satisfaction.

[0225] For example, the matrix strips 112 are arranged in an orderly manner in the matrix segment 11, thereby achieving a high filling rate of the matrix segment 11 while also improving the uniformity of the matrix segment 11, thus achieving uniform release of aerosols.

[0226] In some embodiments, the ratio of the mass of the matrix segment 11 to the mass of the aerosol-generated article 10 is greater than or equal to 45%.

[0227] In this way, under the condition that the mass of the aerosol generating product 10 is constant, the aerosol generating product 10 can have a matrix segment 11 of a certain mass, thereby having a certain amount of smoke, which is conducive to improving the smoking satisfaction.

[0228] Here, the density of matrix strip 112 is set to be greater than or equal to 1000 mg / cm³. 3 The filling rate of the matrix segment 11 is set to be greater than or equal to 65%, and the ratio of the mass of the matrix segment 11 to the mass of the aerosol-generated product 10 is set to be greater than or equal to 45%. That is, the high load of the matrix segment 11 is achieved by the high density and high filling rate of the matrix strip 112.

[0229] In some embodiments, the length of the aerosol-generating article 10 is in the range of 45 mm to 120 mm, and the ratio of the length of the matrix segment 11 to the length of the aerosol-generating article 10 is greater than or equal to 15% and less than or equal to 35%.

[0230] For example, the length of the aerosol-generating article 10 can be any one of 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, 100mm, 110mm, 120mm or any combination thereof.

[0231] By setting the length of the aerosol generating article 10 to be in the range of 45mm to 120mm, and setting the ratio of the length of the matrix section 11 to the length of the aerosol generating article 10 to be greater than or equal to 15% and less than or equal to 35%, the size of the aerosol generating article 10 can be appropriate. Under the condition that the length of the aerosol generating article 10 is fixed, the aerosol generating article 10 can have a matrix section 11 of a certain length, thereby having a certain amount of smoke. The aerosol generating article 10 can also have a functional section 13 and / or a front plug section 12 of a certain length, which is beneficial to improving the inhalation experience.

[0232] For example, the equivalent diameter of the aerosol-generating article 10 is in the range of 5 mm to 7.5 mm.

[0233] The equivalent diameter of the aerosol-generated product 10 can be any one of 5mm, 5.2mm, 5.3mm, 5.5mm, 5.8mm, 6mm, 6.2mm, 6.5mm, 6.8mm, 7mm, 7.2mm, 7.5mm or any combination thereof.

[0234] By setting the equivalent diameter of the aerosol generating product 10 to be in the range of 5 mm to 7.5 mm, the heating uniformity and stability of the aerosol generating product 10 are improved, the extraction efficiency and utilization rate of the aerosol generating product 10 are increased, the consistency of aerosol release is enhanced, and the quality of aerosols is improved.

[0235] In some embodiments, as shown in Figures 2 and 3, at least one airflow channel 114 is formed between at least a portion of the matrix strips 112 within the matrix segment 11, and the airflow channel 114 extends along the length direction of the matrix strips 112.

[0236] The number of airflow channels 114 can be one or more.

[0237] When the aerosol matrix sheet is rolled or gathered to form a matrix segment 11, there is a certain gap between adjacent matrix strips 112, which can form an airflow channel 114.

[0238] The airflow channel 114 extends along the length of the matrix strip 112, which facilitates the flow of air along the length of the matrix strip 112. On the one hand, it can promote the generation of aerosols in the matrix strip 112, and on the other hand, it can carry the generated aerosols to the user, which is beneficial to the generation and migration of aerosols.

[0239] In some embodiments, the suction resistance of the front plug section 12 is greater than 0 and less than or equal to 5 mm of water column.

[0240] By ensuring that the suction resistance of the front plug section 12 is greater than 0 and less than or equal to 5 mm of water column, it is beneficial to increase the air intake of the aerosol generating product 10, thereby facilitating the generation and extraction of aerosols. It also ensures that the suction resistance of the aerosol generating product 10 is appropriate, thus improving the user experience.

[0241] In some embodiments, the suction resistance of functional segment 13 is greater than or equal to 10 mm water column and less than or equal to 50 mm water column.

[0242] The suction resistance of functional segment 13 can be any one of the following values ​​or any value between two of them: 10mmH2O, 13mmH2O, 15mmH2O, 18mmH2O, 19mmH2O, 20mmH2O, 23mmH2O, 25mmH2O, 28mmH2O, 30mmH2O, 33mmH2O, 35mmH2O, 38mmH2O, 40mmH2O, 42mmH2O, 45mmH2O, 48mmH2O, and 50mmH2O.

[0243] Since the suction resistance of functional section 13 is greater than or equal to 10 mm water column and less than or equal to 50 mm water column, it helps to ensure that the suction resistance of the aerosol generating product 10 is appropriate, reducing the user's suction force and minimizing aerosol output jamming or instability, thus improving the suction experience and user comfort. Furthermore, it also helps to improve the filtration and / or cooling effect of the aerosol.

[0244] In some embodiments, as shown in Figures 1 and 2, the peripheral sidewall of functional segment 13 is provided with at least one air inlet 134.

[0245] The number of air intake vents 134 can be one or more.

[0246] For example, the air inlet 134 can be connected to the hollow channel 1311 inside the functional section 13. In other words, the hollow channel 1311 inside the functional section 13 is connected to the outside of the functional section 13 through the air inlet 134.

[0247] Here, the functional section 13 has an air inlet 134 that passes through the side wall of the hollow channel 1311. That is, the air inlet 134 passes through the side wall of the hollow channel 1311 and is connected to the hollow channel 1311.

[0248] For example, the wrapping layer 135 has an airflow channel 114 formed at the position corresponding to the air inlet 134 to avoid the air inlet 134.

[0249] In this embodiment, at least one air inlet 134 is provided on the peripheral sidewall of the functional section 13, so that external air can enter the interior of the functional section 13 through the air inlet 134, which is beneficial to cooling the aerosol inside the functional section 13, thereby further improving the cooling effect of the functional section 13.

[0250] By adding a lateral air intake channel (i.e., air inlet 134), the internal and external environmental pressure of the airflow circulation is adjusted, which helps to improve the problem of slow aerosol extraction efficiency in the front section of the bottom air intake aerosol generation device 20 under the circumferential heating mode, reduces the transmission temperature of the extracted aerosol, and adjusts the absorption resistance (RTD) of the aerosol generation product 10.

[0251] In some embodiments, please refer to Figures 1 to 3, the front plug section 12, the matrix section 11 and the functional section 13 are cylinders and are arranged coaxially, and the arrangement direction of the front plug section 12, the matrix section 11 and the functional section 13 is the axial direction of the front plug section 12, the matrix section 11 and the functional section 13.

[0252] By setting the front plug section 12, matrix section 11 and functional section 13 as cylinders and arranging them sequentially along the axial direction of the front plug section 12, matrix section 11 and functional section 13, the structure of the aerosol generating product 10 can be made more compact, improving the user experience.

[0253] In some embodiments, the volume of the hollow channel 1311 is greater than or equal to 15 mm². 3 and less than or equal to 130mm 3 .

[0254] The volume of the hollow channel 1311 can be 15mm. 3 20mm 3 25mm 3 30mm 3 35mm 3 40mm 3 45mm 3 50mm 3 55mm 3 60mm 3 65mm 3 70mm 3 75mm 3 80mm 3 90mm 3 100mm 3 105mm 3 110mm 3 120mm 3 130mm 3 The point value of any one of them or the point value between any two.

[0255] Here, the volume of the hollow channel 1311 is set to be greater than or equal to 15mm. 3 and less than or equal to 130mm 3 This can further balance the nucleation and agglomeration of aerosols and provide suitable suction resistance, while also allowing the gas to have a faster airflow velocity in the hollow channel 1311, enhancing the impact of aerosols during inhalation, improving the throat hit sensation, reducing aerosol retention, and thus improving the inhalation experience.

[0256] In some embodiments, the ratio of the mass of the hollow tube segment 131 to the volume of the hollow channel 1311 is greater than or equal to 1 mg / mm². 3 .

[0257] The heat capacity of the hollow tube section 131 is related to its mass. If the mass of the hollow tube section 131 is small, the heat capacity of the hollow tube section 131 will be small, which will result in a weak heat storage capacity of the hollow tube section 131, thus affecting the heat exchange effect on aerosols.

[0258] The volume of the hollow channel 1311 is related to the amount of aerosol flowing through it.

[0259] Therefore, by ensuring that the ratio of the mass of the hollow tube segment 131 to the volume of the hollow channel 1311 is greater than or equal to 1 mg / mm², 3This allows the ratio of the mass of the hollow tube section 131 to the volume of the hollow channel 1311 to be appropriate, that is, the heat exchange effect of the hollow tube section 131 on the aerosol and the amount of aerosol flowing through the hollow channel 1311 are appropriate, which is conducive to improving the cooling effect and thus improving the taste.

[0260] In some embodiments, the equivalent outer diameter of the hollow tube section 131 is less than or equal to 7 mm.

[0261] By setting the equivalent outer diameter of the hollow tube section 131 to less than or equal to 7 mm, the structural compactness, cooling effect, and suitable suction resistance of the aerosol-generated product 10 can be taken into account, thereby improving the extraction effect and suction taste of the aerosol.

[0262] In some embodiments, the wall thickness of the hollow tube section 131 is greater than or equal to 1.5 mm.

[0263] Here, when the wall thickness of the first air intake channel 1421 is less than 0.05mm, the cooling support section 133 has poor support effect and is prone to deformation. When the wall thickness of the first air intake channel 1421 is greater than 2.9mm, the aerosol extraction channel 123 is too narrow, which affects the amount of smoke generated by the aerosol generating product 1010 and increases the suction resistance of the aerosol generating product 1010.

[0264] In this embodiment, by setting the wall thickness of the hollow tube segment 131 to be greater than or equal to 1.5 mm, the hollow tube segment 131 not only provides a certain supporting effect and structural strength, but also has appropriate suction resistance, which is beneficial for the extraction of aerosols and ensures that the aerosol-generated product 10 has a certain amount of smoke. Furthermore, the heat capacity of the hollow tube segment 131 can be appropriately set, thereby improving the heat exchange effect on the aerosols.

[0265] In some embodiments, the length of the front plug section 12 is in the range of 5 mm to 10 mm.

[0266] The length of the front plug section 12 can be any one of 5mm, 5.2mm, 5.5mm, 5.8mm, 6mm, 6.5mm, 6.8mm, 7mm, 7.2mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm or any combination thereof.

[0267] When the length of the front plug section 12 is less than 5mm, it is not conducive to the adsorption of the backflow aerosol after the front plug section 12 has finished suction, which can easily lead to the condensation of aerosol in the aerosol generating device 20. When the length of the front plug section 12 is greater than 10mm, the suction resistance of the front plug section 12 is large, which affects the bottom air intake, thereby reducing the aerosol carrying efficiency and the suction experience. Therefore, it is more appropriate to set the length of the front plug section 12 between 5mm and 10mm.

[0268] The present disclosure will now be described in further detail with reference to specific embodiments. These descriptions are merely illustrative and not intended to limit the scope of the disclosure.
