[0002] Aerosol generating articles such as modern electronic cigarettes or heat-not-burn (HNB) products are gradually becoming substitutes for traditional tobacco products, aiming to provide users with a safer and cleaner smoking experience.

[0003] HNB-related aerosol generating articles convert aerosol generating materials containing nicotine, flavorings, and other ingredients (mainly aerosol generating agents) into aerosols through different heating mechanisms for users to inhale. Taking HNB cigarettes as an example, in order to increase the aerosol yield of tobacco sheet HNB cigarettes or add flavoring components or other active components to the tobacco sheet, it is necessary to mix the tobacco sheet with aerosol generating capsules, but the tobacco sheet is in the form of a sheet and is generally used in the form of a filament, while the aerosol generating capsules are spherical, and the mixing of the two has great difficulty and uniformity cannot be controlled. If the distribution of the aerosol generating capsules in the tobacco sheet is irregular, the aerosol release uniformity of the corresponding aerosol generating article is poor, thereby affecting the user experience.

[0043] As described in the background section, when the tobacco sheet and the capsule are mixed, the uniformity of the aerosol generating material obtained is poor, and thus the uniformity of the aerosol released by the aerosol generating article is poor.

[0044] To solve the above technical problem, an aerosol generating material and an aerosol generating article are provided, in which the aerosol generating material includes a tobacco sheet and a capsule compounded on the tobacco sheet.

[0045] With the technical solution of the present application, the relative positions of the tobacco sheet and the capsule can be more controllable by compounding the capsule on the tobacco sheet, and thus the distribution of the tobacco sheet and the capsule can be more uniform, especially the capsule can be uniformly distributed in the aerosol generating material, and the aerosol generated is also more uniform, which can improve the user experience. At the same time, the ratio of the tobacco sheet and the capsule can also be more controllable, so as to produce aerosol generating materials that meet the smoking needs of different customers.

[0046] To make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0047] Figure 1 is a schematic view of an aerosol generating material 1 according to an embodiment of the present disclosure. In FIG. 1, (a) is a plan view of the aerosol generating material 1, and (b) is a side view of the aerosol generating material 1.

[0048] Referring to FIG. 1, Figure 1 The aerosol generating material 1 can include a tobacco sheet 12 and a capsule 11 compounded on the tobacco sheet 12.

[0049] In some embodiments, the tobacco sheet 12 can serve as a base material of the aerosol generating material 1.

[0050] In practical applications, the tobacco sheet 12 can be manufactured by crushing tobacco raw materials such as tobacco leaf fragments and tobacco stems, mixing the crushed tobacco raw materials with cellulose materials such as wood pulp fibers, and then using a papermaking method or a casting method to form a continuous sheet.

[0051] In some embodiments, the aerosol generating material 1 can be applied to an aerosol generating article 2 (such as Figure 15 ). The aerosol generating article 2 can include an aerosol generating substrate 21, which can have a cylindrical shape. The aerosol generating material 1 is arranged or rolled into a cylindrical shape to form the aerosol generating substrate 21.

[0052] In some embodiments, the aerosol generating article 2 can include an aerosol generating substrate segment, which includes a housing for wrapping the aerosol generating material 1. The housing can be, for example, a paper tube.

[0053] In some embodiments, the capsule 11 can be an aerosol generating capsule.

[0054] In some embodiments, the aerosol generating capsule includes an aerosol generating agent, which includes at least one of propylene glycol and glycerol.

[0055] The aerosol generating capsule is further described below.

[0056] In some embodiments, the aerosol generating capsule generally includes a core material and a housing wrapping the core material. The housing of the aerosol generating capsule can be broken when the temperature meets certain conditions, so as to release the core material and generate an aerosol. The heating release temperature of the aerosol generating capsule is generally 180-300°C, preferably 200-250°C, and is related to the material and thickness of the capsule housing.

[0057] In some embodiments, the core material inside the aerosol generating capsule is a liquid.

[0058] In some embodiments, the core material of the capsule is a paste, a gel, or a solid-liquid mixture.

[0059] In some embodiments, the core material can include an aqueous liquid formulation containing a heat-releasable smoking material, which includes propylene glycol and glycerol.

[0060] In some embodiments, the housing includes a gel material, which is at least one of animal glue, vegetable glue, microbial glue, starch, and starch modification, and the aerosol generating capsule includes a layer of the housing.

[0061] In some embodiments, the shell can be a photosensitive or thermosensitive polymer resin, such as a polymer shell formed by a photoinitiator under light or a polymer shell formed by cooling after hot melting.

[0062] The aerosol generating capsule used in the embodiments of the present application can be prepared by various methods, such as drop casting, compression, diffusion, coagulation, and rolling, etc.

[0063] In some embodiments, the capsule 11 can be compounded on the tobacco sheet 12 by adhesion or deposition.

[0064] Specifically, the adhesion refers to fixing the capsule 11 on the surface of the tobacco sheet 12 by physical or chemical adhesives. For example, during the manufacturing process of the tobacco sheet 12, an adhesive can be first applied on the surface of the tobacco sheet 12 after the tobacco sheet 12 is formed, and then the capsule 11 can be uniformly attached to the surface of the tobacco sheet 12 by spraying, brushing, or other processes. In this way, the contact surface of the capsule 11 and the tobacco sheet 12 can be tightly attached, avoiding the capsule 11 from falling off during subsequent processing or use. Meanwhile, by controlling the distribution area of the adhesive, the arrangement position of the capsule 12 can be accurately controlled.

[0065] The deposition refers to the natural adhesion in the process. For example, in the casting or papermaking process of the tobacco sheet 12, the capsule 11 particles can be sequentially added during the pulp laying stage, and then the capsule 11 can be naturally embedded in the surface or shallow structure of the tobacco sheet 12 when the tobacco sheet 12 is formed. The capsule can be attached to the surface of the sheet by the viscosity of the pulp itself, such as added glue, etc., and a stable sheet-capsule composite structure can be formed during the drying process.

[0066] As described above, by compounding the capsule 11 on the tobacco sheet 12 by adhesion or deposition, the relative position of the capsule 11 and the tobacco sheet 12 can be accurately controlled by process means (such as fixed-distance application, fixed-distance arrangement, etc.), avoiding the problem of random aggregation or sparse distribution of the capsule 12 in the traditional mixing process. Further, in the compounded material, the capsule 11 forms a stable and uniform distribution on the surface or inside of the tobacco sheet 12, ensuring the release of aerosol generating agents (such as propylene glycol and glycerol) to be more consistent when heated, thereby improving the uniformity of aerosol release.

[0067] In some embodiments, the particle size of the capsule 11 is 0.5-1.5 mm.

[0068] In practical applications, the particle size range of the capsule 11 can ensure the process adaptability during the process of compounding the capsule 11 on the tobacco sheet 12. For example, during the process of compounding the capsule 11 on the tobacco sheet 12, if the particle size of the capsule 11 is too small (e.g., <0.5 mm), the surface attachment area is limited, and the problem of falling off or uneven distribution is prone to occur during fixation by adhesion or deposition process; and if the particle size is too large (e.g., >1.5 mm), the tobacco sheet 12 may be loose in structure during rolling or forming due to the self-weight or volume interference of the capsule 11, and even the flexibility of the tobacco sheet 12 is damaged. The particle size range of 0.5-1.5 mm can not only ensure the bonding strength of the capsule 11 and the tobacco sheet 12, but also maintain the shape stability of the tobacco sheet 12 in subsequent processing (such as rolling into a strip or a cylindrical structure), facilitating processing and manufacturing.

[0069] In some embodiments, the particle size of the capsule 11 compounded in different regions of the tobacco sheet 12 can be different. For example, in the middle part of the tobacco sheet 12 or the region close to the heating element, a higher concentration of aerosol generating agent may be required to ensure rapid and sufficient release of aerosol. At this time, the capsule 11 with a larger particle size (e.g., 1.0-1.5 mm) can accommodate more core materials (e.g., propylene glycol, glycerol), and release more aerosol at one time during heating, meeting the release requirements of the core region. In the edge region of the tobacco sheet 12 or the region away from the heating source, the heating efficiency may be lower. The capsule 11 with a smaller particle size (e.g., 0.5-0.8 mm) can reduce the temperature threshold required for shell rupture, ensuring that the core material can still be fully released under lower heating intensity, avoiding the problem of insufficient aerosol generation in the edge region. In addition, capsules 11 with different particle sizes may correspond to different production costs (e.g., complexity of preparation process, utilization rate of raw materials). By using capsules 11 with different particle sizes in different regions, high-performance but high-cost capsules 11 can be used in key functional areas (e.g., core heating area), and low-cost capsules 11 can be used in non-key areas (e.g., edge area), thereby reducing production costs while ensuring overall performance.

[0070] In some embodiments, the array of capsules 11 is arranged on the tobacco sheet 12. In this way, compared with the random distribution of capsules 11 and tobacco sheet 12 in disorder, the array arrangement of capsules 11 can make the generation of aerosol more uniform.

[0071] In some embodiments, along the longitudinal direction, any two capsules 11 adjacent to each other are at least partially in contact. In other words, along the longitudinal direction, any two capsules 11 adjacent to each other are in close contact. The capsules 11 in close contact along the longitudinal direction can form a continuous heat conduction path. When heated, heat is quickly transferred along the longitudinal direction, causing the shells of the adjacent capsules 11 to break synchronously, releasing the aerosol generating agent (such as propylene glycol, glycerol), avoiding release delay or unevenness caused by insufficient local heating. In use, the longitudinal direction is usually the direction in which the aerosol is inhaled by the user, and high longitudinal heat conduction efficiency is also conducive to the rapid and uniform generation of aerosol.

[0072] In some embodiments, along the transverse direction, the capsules 11 are arranged at intervals. Thus, when rolled into a cylindrical structure, the transverse arrangement at intervals can ensure that the capsules 11 are evenly distributed in the circumferential direction, avoiding deformation or mutual extrusion or even extrusion and breakage of the structure after rolling due to excessive density in the circumferential direction.

[0073] In some embodiments, the distance between any two capsules 11 adjacent to each other along the longitudinal direction is less than the distance between any two capsules 11 adjacent to each other along the transverse direction.

[0074] In some embodiments, referring to Figure 2 and Figure 3 , the aerosol generating material 1 can be in the form of a strip.

[0075] In the embodiment shown in Figure 2 , the aerosol generating material 1 can be directly cut into a strip. Each of the strips of the aerosol generating material 1 includes a row of capsules 11 along the length direction.

[0076] In some embodiments, a plurality of strips of the aerosol generating material 1 are arranged in a bundle to form the aerosol generating substrate 21.

[0077] In some embodiments, a plurality of strips of the aerosol generating material 1 can also be mixed with a plurality of strips of the un-composite capsule 11 tobacco sheet 12 into a bundle structure, and then form the aerosol generating substrate 21.

[0078] In the embodiment shown in Figure 3 , each of the strips of the aerosol generating material 1 may, for example, include two rows of capsules 11, and during use, the aerosol generating material 1 can be folded into a v-shaped structure along the middle line between the two rows of capsules 11 to improve space utilization.

[0079] In some embodiments, referring to Figures 4 to 13 , the aerosol generating material 1 can be in a rolled structure, and the rolled structure can include a rolled piece.

[0080] Specifically, referring to Figure 4 and Figure 5 , the rolled structure includes a single-layer cylindrical structure. The single-layer cylindrical structure may, for example, beFigure 4 The rolled piece 3 is shown. The rolled piece 3 can be formed by longitudinally rolling the long strip of aerosol generating material 1 (as shown), wherein the capsules can be compounded to the inner wall of the tobacco sheet, forming a "capsule inward, sheet outward" stacked structure. Further, to maintain the stability of the cylindrical shape, an adhesive can be applied to fix the longitudinal joint of the rolled piece 3 (i.e. the overlapping area of the starting end and the end of the tobacco sheet); a layer of wrapping paper (such as high air permeability paper or degradable film) can also be wrapped on the outer surface of the rolled piece 3 to enhance the structural rigidity through physical wrapping. Figure 1

[0081] In one specific non-limiting embodiment, the rolled piece 3 can include 6 rows of capsules inside. Along the inner wall of the rolled piece, each circle layer includes 6 capsules.

[0082] In specific applications, Figure 4 The rolled piece 3 formed by the aerosol generating material can be arranged in the central region of the aerosol generating substrate 21. The aerosol generating substrate 21 can refer to Figure 5 The periphery of the rolled piece 3 can continue to be filled with the filamentous tobacco sheet, so that the longitudinal distribution and the circumferential distribution of the capsules have a certain regularity.

[0083] In some embodiments, referring to Figure 6 and Figure 7 The distance between the two adjacent rows of capsules in the aerosol generating material can be further increased. In this scenario, the rolled piece 4 formed by the aerosol generating material can include 4 rows of capsules inside, and the resulting rolled piece 4 can have a smaller diameter. When used in the aerosol generating substrate 21, the aerosol generating substrate 21 can include a plurality of rolled pieces 4. For example, the aerosol generating substrate 21 can include 3 parallel arranged rolled pieces 4. Further, the gap region in the aerosol generating substrate 21 can also be filled with other tobacco materials. For example, capsules and / or tobacco sheets, or strip composite materials of both.

[0084] In some embodiments, referring to Figure 8 and Figure 9 The number of single-layer cylindrical structures is multiple, and the multiple single-layer cylindrical structures are nested with each other. For example, the rolled piece 5 in the form of a single-layer cylindrical structure can also have a larger radius. In this scenario, the number of capsules in each row arranged on the inner wall of the rolled piece 5 can be further increased. For example Figure 8 The rolled piece 5 can have 14 capsules facing the center, as exemplarily shown in

[0085] ​In some embodiments, the hollow structure can also be filled with other aerosol generating materials, such as a plurality of strips of tobacco sheet, or filled with capsules. Alternatively, the hollow structure can also be placed with one or more Figure 4 The rolled piece 3 or Figure 6 The rolled piece 4 shown. By inserting the rolled piece 3 or the rolled piece 4, which is also a single-layer cylindrical structure, into the hollow structure of the rolled piece 5, a nested structure is formed, so that the distribution and ratio of different aerosol generating materials in the aerosol generating substrate can be controlled according to actual needs.

[0086] In some embodiments, the capsules can be compounded on the inner wall and / or the outer wall of the single-layer cylindrical structure.

[0087] In some embodiments, the outer wall of the single-layer cylindrical structure of the inner layer and the inner wall of the single-layer cylindrical structure of the outer layer in the two adjacent layers of the single-layer cylindrical structure are compounded with the capsules, and the capsules compounded in the single-layer cylindrical structure of the inner layer and the capsules compounded in the single-layer cylindrical structure of the outer layer are arranged alternately along the circumference of the single-layer cylindrical structure.

[0088] For example, Figure 10 In the rolled piece 6 shown, the capsules are located on the outer wall of the single-layer cylindrical structure (i.e., the rolled piece 6), and the gap between the capsules on the outer wall increases during the rolling process to form the rolled piece 6. Therefore, the gap between the capsules on the outer wall of the rolled piece 6 can be matched with the gap between the capsules on the inner wall of the rolled piece 7. Figure 11 The rolled piece 7 shown. In the rolled piece 7, the capsules are located on the inner wall of the single-layer cylindrical structure (i.e., the rolled piece 7), so that when the rolled piece 6 and the rolled piece 7 are used together, a structure as shown in Figure 12 The rolled piece 7 shown. In the rolled piece 7, the capsules are located on the inner wall of the single-layer cylindrical structure (i.e., the rolled piece 7), so that when the rolled piece 6 and the rolled piece 7 are used together, a structure as shown in Figure 12 In the rolled piece 6 shown, the capsules are located on the outer wall of the single-layer cylindrical structure (i.e., the rolled piece 6), and the gap between the capsules on the outer wall increases during the rolling process to form the rolled piece 6. Therefore, the gap between the capsules on the outer wall of the rolled piece 6 can be matched with the gap between the capsules on the inner wall of the rolled piece 7.

[0089] In some embodiments, referring to Figure 13 The outermost layer of the rolled structure (i.e., the rolled piece 8) can be formed by continuously rolling the tobacco sheet without the capsules. For example, after the aerosol generating material is made into a complete single-layer cylindrical structure with the capsules facing inwards, a section of the tobacco sheet without the capsules can continue to wrap the single-layer cylindrical structure to form the outermost layer, so that the outermost layer can have multiple layers of the tobacco sheet. In this embodiment, the section of the tobacco sheet without the capsules can be wrapped for 2 layers, and in other embodiments, it can be wrapped for 3 layers, 4 layers, or even more layers, thereby continuously increasing the diameter of the rolled piece 8 and facilitating the production of aerosol generating materials or aerosol generating substrates that meet specific dimensions.

[0090] In some embodiments, referring to Figure 14 and Figure 15The rolled structure (i.e. the rolled piece 9) can comprise a plurality of layers of continuous structure, and the cross-sectional shape of the plurality of layers of continuous structure can be helical.

[0091] In some embodiments, the aerosol generating material (i.e. the sheet of reconstituted tobacco with capsules) can be directly rolled into a plurality of layers to form the rolled piece 9.

[0092] In some embodiments, the rolled piece 9 can be continuously increased in radial dimension during rolling, and when the diameter of the rolled piece 9 approaches the required diameter of the aerosol substrate segment, the rolled piece 9 can be formed into an independent rolled piece by continuing to wrap the sheet around the rolled piece 9, thereby eliminating the need for additional wrapping paper. Figure 13

[0093] In some embodiments, the rolled piece 9 can be rolled to a size that is the same as the inner diameter of the aerosol substrate segment, so that the independent rolled piece 9 forms the aerosol generating substrate, thereby simplifying the production process.

[0094] Figure 16 is a schematic view of an aerosol generating article 2 according to an embodiment of the present application.

[0095] Referring to Figure 16 , the aerosol generating article 2 comprises an aerosol generating substrate 21, which comprises the aerosol generating material 1 as described in the embodiments described above. Figures 1 to 15

[0097] It will be understood that the specific structure of the aerosol generating material 1, the production process, and the form of the aerosol generating material 1 in the aerosol generating substrate 21 (e.g. the formation of the rolled pieces shown in Figures 4 to 15 ) can be described with reference to the embodiments described above with reference to Figures 1 to 15 , and will not be described in detail here.

[0098] In some embodiments, the aerosol generating article 2 can be, for example, an HNB cigarette, and can comprise a three-segment or four-segment structure. As shown in Figure 16 , the aerosol generating article 2 can comprise a proximal end and a distal end along the direction of extension, wherein the proximal end is closer to the user than the distal end when in use. The aerosol generating article 2 can comprise an aerosol generating substrate 21, which is located at the distal end of the aerosol generating article 2. The side of the aerosol generating substrate 21 facing the proximal end is connected to a support 22. ​​

[0099] In some embodiments, the support 22 has the effect of fixing the aerosol substrate 21 and cooling the aerosol.

[0100] Further, the side of the support 22 towards the proximal end can be connected with a hollow section. The hollow section can further cool the aerosol.

[0101] Further, the proximal end of the aerosol generating article 2 is provided with a filter 23. The filter 23 can include a hollow filter, a solid filter, or a combination of both.

[0102] From the above, by using the technical solution of the present application, the relative position of the tobacco sheet 12 and the capsule 11 can be more controllable through the design of the capsule 11 compounded on the tobacco sheet 12, and the distribution of the tobacco sheet 12 and the capsule 11 is more uniform, the generated aerosol is also more uniform, and the user's use experience can be effectively improved. At the same time, the ratio of the tobacco sheet 12 and the capsule 11 can also be more controllable, so as to produce aerosol generating materials that meet the smoking needs of different customers.
