Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to a product segment, an aerosol generation product, and an aerosol generation system. Background Technology

[0002] This section is intended to provide background or context for embodiments of this application. The description herein is not intended to imply that it is prior art simply because it is included in this section.

[0003] In related technologies, aerosol generating products can generate aerosols by heating without combustion. The aerosol generating products include product segments, which can be used to achieve at least one function of the aerosol generating products. Improving the connection strength of the product segments is an important research direction in the field of aerosol generation technology. Summary of the Invention

[0004] In view of this, embodiments of this application aim to provide a product segment, an aerosol-generating product, and an aerosol-generating system that can improve the connection strength of the product segment.

[0005] The first aspect of this application provides an article segment, comprising:

[0006] An inner matrix and an outer layer, both extending along a first direction, the outer layer surrounding the outer periphery of the inner matrix, the inner matrix having a first circumferential surface facing the outer layer, and the outer layer having a second circumferential surface facing the inner matrix, wherein at least a portion of the first circumferential surface and the second circumferential surface are in a stop-fitting relationship.

[0007] In some embodiments, at least one of the first circumferential surface and the second circumferential surface is provided with a protrusion for a stop-fit.

[0008] In some embodiments, both the first circumferential surface and the second circumferential surface are provided with the protrusions, and the protrusions on the first circumferential surface and the protrusions on the second circumferential surface are spaced apart circumferentially.

[0009] In some embodiments, the two end faces of the protrusion along the first direction are flush with the two end faces of the article segment along the first direction.

[0010] In some embodiments, there are multiple protrusions, and the multiple protrusions are evenly spaced along the circumference.

[0011] In some embodiments, a plane perpendicular to the first direction is used as the projection surface, and the projection shape of the protrusion is any one of the following: arc shape, quadrilateral shape, dovetail shape, sawtooth shape, or irregular shape.

[0012] In some embodiments, there are multiple protrusions, with a plane perpendicular to the first direction as the projection surface, and at least two of the protrusions have different projection shapes.

[0013] In some embodiments, at least one of the first circumferential surface and the second circumferential surface is provided with a groove.

[0014] In some embodiments, the groove extends through at least one end face of the article segment along a first direction.

[0015] In some embodiments, both the first circumferential surface and the second circumferential surface are provided with the groove, and the grooves of the first circumferential surface and the grooves of the second circumferential surface are spaced apart circumferentially.

[0016] In some embodiments, there are multiple grooves, and the multiple grooves are evenly spaced along the circumference.

[0017] In some embodiments, one of the first circumferential surface and the second circumferential surface is provided with a protrusion, and the other of the first circumferential surface and the second circumferential surface is provided with a groove, wherein the protrusion abuts against the groove wall surface.

[0018] In some embodiments, the inner matrix and the outer layer are co-extruded.

[0019] A second aspect of this application provides an aerosol-generating article, comprising the article segment described in any of the preceding claims.

[0020] A third aspect of this application provides an aerosol generation system, including an aerosol generation device and the aforementioned aerosol generation article. The aerosol generation device includes a heating element for heating the aerosol generation article to generate aerosols.

[0021] The product segment provided in this application embodiment has several advantages. Firstly, the first and second circumferential surfaces engage in a stop-and-go fit, exerting mutual force between the inner matrix and the outer layer. This allows the inner matrix and outer layer to abut against each other, enhancing the connection stability and preventing relative rotation between them, thus improving the overall connection strength of the product segment. Secondly, when the product segment is used as the functional segment, it needs to provide support and cooling. Good bonding strength between the inner matrix and the outer layer ensures the product segment has good connection strength, preventing separation or loosening. This helps avoid the problem of the functional segment separating and loosening, which could hinder the use of the aerosol-generated product. Thirdly, when the product segment is used as the matrix segment, the inner matrix and outer layer can each produce aerosols with different flavors. By changing the heating method, users can sequentially inhale aerosols of different flavors, or they can inhale a mixed-flavor aerosol. Of course, the inner matrix and outer layer can also produce aerosols of the same flavor, thus meeting diverse user needs regarding aroma intensity, strength, and flavor richness, enhancing the user experience.

[0047] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

Therefore, it should not be construed as a limitation on the embodiments of this application.

[0049] The various specific technical features and embodiments described in the detailed embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features / embodiments can form different implementation methods. To avoid unnecessary repetition, the various possible combinations of various specific technical features / embodiments in this application will not be described separately. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] It should be noted that in this application, "at least one" refers to a quantity including one or more. "At least two" and "more" refer to a quantity including two or more.

[0051] Please see Figures 1 to 15 This application provides an embodiment of a product segment 1000, at least one of a matrix segment 10 and a functional segment 20 using the product segment 1000. The product segment 1000 includes an inner matrix 1 and an outer layer 2, both extending along a first direction. The outer layer 2 surrounds the outer periphery of the inner matrix 1. The inner matrix 1 has a first circumferential surface 1a facing the outer layer 2, and the outer layer 2 has a second circumferential surface 2a facing the inner matrix 1. At least a portion of the first circumferential surface 1a and the second circumferential surface 2a are in a stop-fitting relationship.

[0052] The matrix segment 10 is used to generate an aerosol by heating. Exemplarily, the matrix segment 10 can be adapted to generate an aerosol by heating without combustion. That is, the matrix segment 10 is heated below its ignition point to generate an aerosol. The matrix segment 10 does not burn during the aerosol generation process. In some applications, the matrix segment 10 can also be adapted to generate an aerosol by ignition. The matrix segment 10 provided in this application embodiment primarily generates an aerosol by heating without combustion.

[0053] As an example, functional segment 20 may provide at least one of the following: filtration function, adsorption function, aroma enhancement function, dilution function, cooling function, and resistance adjustment function.

[0054] Filtration function refers to the function of filtering out at least some of the particulate matter in aerosols.

[0055] Adsorption function refers to the ability to adsorb at least some impurities in aerosols. It can be understood that these impurities are substances that remove the active ingredients from the aerosol; the active ingredients are those that need to be provided to the user.

[0056] The aroma-enhancing function refers to the function of adding aroma-producing components to aerosols.

[0057] The dilution function refers to the function of reducing the concentration of active ingredients in aerosols.

[0058] Cooling function refers to the function of reducing the temperature of aerosols.

[0059] The suction resistance adjustment function refers to the function of reducing or increasing suction resistance. In this way, the flow rate and distribution of aerosols can be controlled, and the suction resistance and aerosol uniformity can be optimized.

[0060] The use of product segment 1000 in at least one of matrix segment 10 and functional segment 20 means that: matrix segment 10 may use product segment 1000, functional segment 20 may use product segment 1000, or both matrix segment 10 and functional segment 20 may use product segment 1000.

[0061] Taking the matrix segment 10 using the product segment 1000 as an example, both the inner matrix 1 and the outer layer 2 can release aerosols when heated.

[0062] For example, the inner matrix 1 and the outer layer 2 can both extend to the same length along the first direction, thus facilitating the production of the article segment 1000. The inner matrix 1 and the outer layer 2 can also extend to different lengths along the first direction, thus enabling the article segment 1000 to be adapted to aerosol-generated articles 100 with different requirements.

[0063] In one embodiment, the matrix segment 10 is made of product segment 1000, and the inner matrix 1 and outer layer 2 are made of materials with different flavors, so that the matrix segment 10 can produce aerosols with different flavors. For example, at least one component of the inner matrix 1 and the outer layer 2 is different, or the content of at least one component of the inner matrix 1 and the outer layer 2 is different, both of which can produce different flavors.

[0064] In another embodiment, both the inner matrix 1 and the outer layer 2 are made of the same flavored material, thereby enhancing the richness of the aerosol's flavor. For example, all components and amounts of the inner matrix 1 and the outer layer 2 are identical.

[0065] For example, a heating element can be disposed inside the substrate segment 10 to perform central heating of the substrate segment 10. Central heating refers to the heating element being inserted into the inner substrate 1 to bake and heat the substrate segment 10 radially from the inside out. A heating element can be disposed on the outer periphery of the substrate segment 10 to perform circumferential heating of the substrate segment 10. Circumferential heating refers to the heating element being disposed on the outer periphery of the outer jacket layer 2 to bake and heat the substrate segment 10 radially from the outside in. A heating element can be disposed at the distal lip end of the substrate segment 10 to perform bottom heating of the substrate segment 10. Bottom heating refers to the heating element being disposed at the bottom, i.e., the distal lip end, of the inner substrate 1 and the outer jacket layer 2 to bake and heat the substrate segment 10 from the distal lip end to the proximal lip end.

[0066] It should be noted that the radial direction is perpendicular to the first direction, and the radial direction is the direction of a ray passing through the center line of the product segment 1000 in a plane perpendicular to the first direction. "Inner" refers to the side radially closer to the center line, and "outer" is the opposite of "inner," referring to the side radially farther from the center line. "Proximal lip end" refers to the direction along the first direction closer to the user's lip, and "distal lip end" refers to the direction along the first direction farther from the user's lip.

[0067] For example, the inner substrate 1 can be heated first, followed by the outer layer 2. In this case, the user first inhales the aerosol generated by the inner substrate 1, and then the aerosol generated by the outer layer 2. Alternatively, the outer layer 2 can be heated first, followed by the inner substrate 1. In this case, the user first inhales the aerosol generated by the outer layer 2, and then the aerosol generated by the inner substrate 1. Furthermore, both the inner substrate 1 and the outer layer 2 can be heated simultaneously, allowing the user to inhale a mixed-flavor aerosol generated by the two media. Thus, by changing the heating method, the user can sequentially inhale different flavored aerosols, or they can inhale a mixed-flavor aerosol, improving the user experience.

[0068] Please see Figure 1 and Figure 2 The first circumferential surface 1a refers to the outer circumferential surface of the inner substrate 1 surrounding the first direction, and the second circumferential surface 2a refers to the inner circumferential surface of the outer jacket 2 surrounding the first direction. For an example, please refer to [link to example]. Figure 3 and Figure 4 The inner matrix 1 is roughly cylindrical, meaning that the first circumferential surface 1a is a cylindrical outer circumferential surface. The outer layer 2 is roughly annular, meaning that the second circumferential surface 2a is an annular inner circumferential surface.

[0069] The at least partial stop-and-resistance fit between the first circumferential surface 1a and the second circumferential surface 2a means: a partial stop-and-resistance fit between the first circumferential surface 1a and the entire second circumferential surface 2a; or, a complete stop-and-resistance fit between the first circumferential surface 1a and a partial stop-and-resistance fit between the second circumferential surface 2a; or, a complete stop-and-resistance fit between the first circumferential surface 1a and the entire second circumferential surface 2a.

[0070] The first circumferential surface 1a and the second circumferential surface 2a abutting fit refer to the precise positioning and fit of the inner matrix 1 and the outer layer 2 through mutual contact (abutting) during molding. In this way, the inner matrix 1 and the outer layer 2 exert mutual force, allowing them to press firmly against each other, thereby enhancing the connection stability between the inner matrix 1 and the outer layer 2. Relative rotation between the inner matrix 1 and the outer layer 2 is difficult to occur, improving the overall connection strength of the product segment 1000 and enhancing connection reliability.

[0071] Taking functional segment 20 using workpiece segment 1000 as an example, please refer to [link to example]. Figure 16 The functional segment 20 includes a support segment 21, which can withstand the temperature of the aerosol from the matrix segment 10 and maintain its shape. The support segment 21 provides support. Thus, through the abutment fit between the inner matrix 1 and the outer layer 2, the connection strength of the support segment 21 is improved, thereby providing better support for the matrix segment 10. During the production process of the support segment 21, the inner matrix 1 and the outer layer 2 are firmly connected and not easily separated.

[0072] It is understandable that when the matrix segment 10 adopts the product segment 1000, the matrix segment 10 also has good connection strength. During the production process of the matrix segment 10, the inner matrix 1 and the outer layer 2 are firmly connected and not easily separated.

[0073] The product segment 1000 provided in this application embodiment has several advantages. Firstly, the first circumferential surface 1a and the second circumferential surface 2a engage in a stop-and-go fit, and the inner matrix 1 and outer jacket 2 exert mutual force, allowing them to abut against each other. This enhances the connection stability between the inner matrix 1 and outer jacket 2, making relative rotation between them difficult and improving the overall connection strength of the product segment 1000. Secondly, when the functional segment 20 uses the product segment 1000, it needs to provide support and cooling. The good bonding strength between the inner matrix 1 and outer jacket 2 ensures the product segment 1000 has good connection strength, making it less prone to separation or loosening. This can, to some extent, prevent the functional segment 20 from separating and loosening, thus avoiding the problem of the aerosol-generated product 100 being unusable. Thirdly, when the matrix segment 10 uses the product segment 1000, the inner matrix 1 and outer jacket 2 can generate aerosols with different flavors. By changing the heating method, users can sequentially draw in aerosols of different flavors, or they can draw in a mixed-flavor aerosol. Of course, the inner matrix 1 and the outer layer 2 can also produce aerosols with the same flavor, thereby meeting users' diverse needs for aerosol aroma intensity, strength, and richness of taste, and improving the user experience.

[0074] It should be noted that, in this embodiment, the first direction does not specifically refer to the direction in which the outer contour of the matrix segment 10 is longest. Specifically, the arrangement direction of the functional segment 20 and the matrix segment 10 is consistent with the first direction; the direction in which the aerosol generating article 100 is inserted into the device and the direction in which the aerosol generating article 100 is removed from the device are both parallel to the first direction. The length of the matrix segment 10 along the first direction can be longer, shorter, or the same as its length in other directions.

[0075] For example, when the outer contour of the matrix segment 10 is cylindrical, the first direction is the axial direction of the matrix segment 10. It should be noted that even when the axial length of the matrix segment 10 is less than its diameter, the first direction of the matrix segment 10 is still the axial direction. As another example, when the outer contour of the matrix segment 10 is cuboid, the first direction is still the direction defined above, that is, the arrangement direction of the functional segment 20 and the matrix segment 10, or the direction in which the heating chamber picks up and puts in the aerosol-generated product 100. The first direction of the matrix segment 10 can be any of the length, width, or height of the cuboid.

[0076] In one embodiment, the matrix segment 10 is a one-piece structure. For example, the matrix segment 10 can be manufactured into a one-piece structure through processes such as injection molding, die casting, or extrusion. Thus, during use, such as when heated and sucked in or after heating ceases, the matrix segment 10 remains a single, integrated medium, making it less prone to disintegration and falling off.

[0077] In one embodiment, the functional segment 20 can be a one-piece structure. For example, the functional segment 20 can be made into a one-piece structure by processes such as injection molding, die casting, or extrusion.

[0078] In one embodiment, the matrix segment 10 and the functional segment 20 are integrally formed. That is, the matrix segment 10 and the functional segment 20 are different parts of a unified whole, rather than two independent structures, nor two independent structures that are separately prepared and then connected together. In this way, the gap between the matrix segment 10 and the functional segment 20 can be reduced or even eliminated, thereby improving the overall bonding strength of the aerosol-generated article 100.

[0079] In another embodiment, the matrix segment 10 and the functional segment 20 can also be separate structures. That is, the matrix segment 10 and the functional segment 20 can be manufactured separately and then connected together. This reduces manufacturing difficulty.

[0080] In some embodiments, please refer to Figures 5 to 11 At least one of the first circumferential surface 1a and the second circumferential surface 2a is provided with a protrusion 3, which is used for a stop-fit. In this way, the protrusion 3 can increase the contact area between the first circumferential surface 1a and the second circumferential surface 2a, thereby enhancing the connection stability between the inner substrate 1 and the outer jacket layer 2 and improving the overall connection strength of the product segment 1000.

[0081] In one embodiment, a protrusion 3 is provided on the first circumferential surface 1a, and the protrusion 3 of the first circumferential surface 1a abuts against the second circumferential surface 2a. In another embodiment, a protrusion 3 is provided on the second circumferential surface 2a, and the protrusion 3 of the second circumferential surface 2a abuts against the first circumferential surface 1a. In yet another embodiment, both the first circumferential surface 1a and the second circumferential surface 2a are provided with protrusions 3, and the protrusion 3 of the first circumferential surface 1a abuts against the second circumferential surface 2a, and the protrusion 3 of the second circumferential surface 2a abuts against the first circumferential surface 1a.

[0082] In some embodiments, please refer to Figure 8 Both the first circumferential surface 1a and the second circumferential surface 2a are provided with protrusions 3, and the protrusions 3 of the first circumferential surface 1a and the second circumferential surface 2a are spaced apart in the circumferential direction. That is to say, the protrusions 3 of the first circumferential surface 1a and the protrusions 3 of the second circumferential surface 2a are distributed at intervals around the first direction.

[0083] In this way, on the one hand, the protrusions 3 on the first circumferential surface 1a and the second circumferential surface 2a can form multi-point support and fit, thereby significantly improving the overall connection strength of the product segment 1000. On the other hand, it can avoid direct contact between the protrusions 3 on the first circumferential surface 1a and the protrusions 3 on the second circumferential surface 2a, which would lead to assembly difficulties or stress concentration, thereby effectively dispersing the forces exerted between the inner substrate 1 and the outer jacket 2, and preventing local deformation or damage to the product segment 1000.

[0084] In some embodiments, please refer to Figure 9 and Figure 10 The two end faces of the protrusion 3 along the first direction are flush with the two end faces of the product segment 1000 along the first direction. That is to say, the inner substrate 1, the outer jacket 2, and the protrusion 3 have the same length along the first direction. This not only facilitates the manufacturing of the product segment 1000, but also ensures that the first circumferential surface 1a or the second circumferential surface 2a maintains a stop-fit ​​with the protrusion 3 along the first direction, thereby further enhancing the connection stability of the inner substrate 1 and the outer jacket 2 and improving the overall connection strength of the product segment 1000.

[0085] In some embodiments, please refer to Figure 9 and Figure 10 The protrusion 3 extends in a straight line along the first direction. This not only facilitates design and production, but also allows the protrusion 3 to maintain a relatively straight posture, making the stress on the inner substrate 1 and the outer layer 2 more uniform.

[0086] In some embodiments, please refer to Figures 5 to 10 There is at least one protrusion 3. For example, the first circumferential surface 1a has at least one protrusion 3, while the second circumferential surface 2a does not have a protrusion 3. Another example is that the second circumferential surface 2a has at least one protrusion 3, while the first circumferential surface 1a does not have a protrusion 3. Yet another example is that the first circumferential surface 1a has at least one protrusion 3, and the second circumferential surface 2a has at least one protrusion 3. By changing the position and number of protrusions 3, the product segment 1000 can be adapted to aerosol-generating products 100 with different requirements.

[0087] It should be noted that the number of protrusions 3 on the first circumferential surface 1a and the number of protrusions 3 on the second circumferential surface 2a may be the same or different. The embodiments of this application do not limit the quantitative relationship between the two.

[0088] In some embodiments, please refer to Figures 5 to 10 There are multiple protrusions 3, which are evenly spaced along the circumference. That is, the distance between any two adjacent protrusions 3 is equal. In this way, on the one hand, it is easy to achieve a precise fit between the inner matrix 1 and the outer layer 2. On the other hand, the forces exerted between the inner matrix 1 and the outer layer 2 can be evenly distributed, which not only enhances the connection stability between the inner matrix 1 and the outer layer 2, but also further prevents the product segment 1000 from deforming or being damaged.

[0089] For example, the first circumferential surface 1a has multiple protrusions 3, and the distance between any two adjacent protrusions 3 of the first circumferential surface 1a is the same. For example, the second circumferential surface 2a has multiple protrusions 3, and the distance between any two adjacent protrusions 3 of the second circumferential surface 2a is the same.

[0090] In some embodiments, there are multiple protrusions 3 on the first circumferential surface 1a and multiple protrusions 3 on the second circumferential surface 2a, and the multiple protrusions 3 on the first circumferential surface 1a and the multiple protrusions 3 on the second circumferential surface 2a are evenly spaced along the circumferential direction.

[0091] In one embodiment, at least one protrusion 3 of a second circumferential surface 2a is provided between any two adjacent protrusions 3 of the first circumferential surface 1a.

[0092] In another embodiment, at least one protrusion 3 of the first circumferential surface 1a is provided between any two adjacent protrusions 3 of the second circumferential surface 2a.

[0093] In another embodiment, the protrusions 3 of all the first circumferential surfaces 1a are located in the first region of the product segment 1000 along the circumferential direction, and the protrusions 3 of all the second circumferential surfaces 2a are located in the second region of the product segment 1000 along the circumferential direction. The first region and the second region are two different regions of the product segment 1000 along the circumferential direction.

[0094] In another embodiment, all the protrusions 3 on the first circumferential surface 1a and all the protrusions 3 on the second circumferential surface 2a are mirror-symmetrical along the central axis of the article segment 1000.

[0095] In some embodiments, please refer to Figures 5 to 11 The protrusion 3 located on the first circumferential surface 1a is an inner protrusion 31, and the protrusion 3 located on the second circumferential surface 2a is an outer protrusion 32. The multiple inner protrusions 31 and the multiple outer protrusions 32 are distributed alternately along the circumferential direction. That is, there is an outer protrusion 32 between any two adjacent inner protrusions 31, and there is an inner protrusion 31 between any two adjacent outer protrusions 32.

[0096] In one embodiment, please refer to Figure 8 Multiple inner protrusions 31 and multiple outer protrusions 32 are evenly and alternately distributed circumferentially. That is, the distance between any two adjacent inner protrusions 31 is equal to the distance between any two adjacent outer protrusions 32. Thus, during production, the multiple inner protrusions 31 and multiple outer protrusions 32 can be arranged on the first circumferential surface 1a and the second circumferential surface 2a using the same design, reducing manufacturing difficulty. During installation, for example, by placing any one inner protrusion 31 against the center position between two outer protrusions 32, the other protrusions can be positioned, facilitating the connection between the inner substrate 1 and the outer jacket layer 2, reducing installation difficulty, significantly improving production efficiency, and enabling a more precise fit between the inner substrate 1 and the outer jacket layer 2.

[0097] In some embodiments, the first circumferential surface 1a has 1 to 36 protrusions 3. For example, the number of protrusions 3 on the first circumferential surface 1a can be 1, 2, 4, 8, 16, 32, or 36, etc. By setting an appropriate number of protrusions 3, not only can the connection stability between the inner matrix 1 and the outer layer 2 be enhanced, but the volume of the inner matrix 1 can also be increased, so that the inner matrix 1 can generate more aerosols and improve the user experience.

[0098] In some embodiments, the second circumferential surface 2a has 1 to 36 protrusions 3. For example, the number of protrusions 3 on the second circumferential surface 2a can be 1, 2, 4, 8, 16, 32, or 36, etc. By setting an appropriate number of protrusions 3, not only can the connection stability between the inner substrate 1 and the outer jacket 2 be enhanced, but the volume of the outer jacket 2 can also be increased, allowing the outer jacket 2 to generate more aerosols and improve the user experience.

[0099] In some embodiments, the first circumferential surface 1a has 1 to 36 protrusions 3, and the second circumferential surface 2a has 1 to 36 protrusions 3. That is, the article segment 1000 includes between 2 and 72 protrusions 3.

[0100] In other embodiments, the first circumferential surface 1a and the second circumferential surface 2a together have 1 to 36 protrusions 3.

[0101] In some embodiments, please refer to Figures 5 to 8 The projection plane is a plane perpendicular to the first direction. The projection shape of the protrusion 3 is any one of the following: arc, quadrilateral, dovetail, sawtooth, or irregular shape.

[0102] In one embodiment, please refer to Figure 7 The protrusion 3 is arc-shaped. This reduces stress concentration and makes the contact between the first circumferential surface 1a and the second circumferential surface 2a smoother, facilitating assembly and disassembly.

[0103] For example, the protrusions 3 of both the first circumferential surface 1a and the second circumferential surface 2a are arc-shaped.

[0104] In one embodiment, please refer to Figure 5 and Figure 6 The protrusion 3 is quadrilateral. This provides a larger contact area, enhancing the connection stability between the inner matrix 1 and the outer layer 2. In addition, the edges of the quadrilateral protrusion 3 can restrict the circumferential movement of the inner matrix 1 and the outer layer 2, preventing relative displacement between them.

[0105] For example, the protrusions 3 of both the first circumferential surface 1a and the second circumferential surface 2a are quadrilateral.

[0106] In one embodiment, please refer to Figure 6 The protrusion 3 is dovetail-shaped. The dovetail shape means that the projected shape of the protrusion 3 is trapezoidal. This can better prevent the relative displacement of the inner matrix 1 and the outer layer 2 under stress, and has better tensile strength and stability.

[0107] For example, the protrusions 3 on both the first circumferential surface 1a and the second circumferential surface 2a are dovetail-shaped.

[0108] In one embodiment, please refer to Figure 8 The protrusion 3 is serrated. In this way, the serrated protrusion 3 can increase the friction and interlocking force, prevent the inner matrix 1 and the outer layer 2 from loosening and falling off when under force, and further improve the connection stability of the product segment 1000.

[0109] For example, the protrusions 3 of both the first circumferential surface 1a and the second circumferential surface 2a are serrated.

[0110] In one embodiment, the protrusion 3 is irregularly shaped. This allows for customization to meet different needs and achieve specific functions, such as optimizing heat transfer paths.

[0111] Irregular shapes refer to shapes that are not regular or asymmetrical.

[0112] In other embodiments, the protrusion 3 may also be a polygon such as a rhombus, pentagon, or hexagon, or it may be wavy. For example, the protrusions 3 of both the first circumferential surface 1a and the second circumferential surface 2a are any one of trapezoidal, rhomboid, or wavy shapes.

[0113] In this embodiment, by setting a protrusion 3 of a suitable shape, the overall connection strength of the product segment 1000 and the need to achieve different functions can be taken into account.

[0114] It should be noted that the specific shape of the protrusion 3 is not limited in the embodiments of this application. The protrusion 3 can also be any other shape, such as a teardrop shape or an ellipse, etc., which will not be elaborated here.

[0115] In some embodiments, please refer to Figure 8There are multiple protrusions 3, with a plane perpendicular to the first direction as the projection surface, and at least two protrusions 3 have different projected shapes. That is, at least two protrusions 3 have different shapes. For example, some protrusions 3 are arc-shaped, and others are quadrilateral. Another example is that some protrusions 3 are dovetail-shaped, and others are serrated. Yet another example is that all protrusions 3 on the first circumferential surface 1a are hexagonal, and all protrusions 3 on the second circumferential surface 2a are rhomboid. Yet another example is that some protrusions 3 on the first circumferential surface 1a are arc-shaped, and others are hexagonal; some protrusions 3 on the second circumferential surface 2a are dovetail-shaped, and others are serrated. The embodiments of this application do not limit the specific combination method, and will not be elaborated further here.

[0116] In this embodiment, when the product segment 1000 includes multiple protrusions 3, by changing the shape of at least two protrusions 3, not only can the connection strength between the inner substrate 1 and the outer jacket 2 be enhanced, but different functional requirements can also be achieved, thereby expanding the applicability of the product segment 1000 and meeting the diversified needs of the market.

[0117] In some embodiments, please refer to Figure 5 , Figures 12 to 15 At least one of the first circumferential surface 1a and the second circumferential surface 2a is provided with a groove 4.

[0118] For example, consider a first circumferential surface 1a with a groove 4 and a second circumferential surface 2a without a groove 4. That is, the area of ​​the first circumferential surface 1a located in the groove 4 is spaced apart from the corresponding area of ​​the second circumferential surface 2a. Thus, when the matrix segment 10 uses the product segment 1000, on the one hand, the groove 4 can serve as an air passage or a buffer space for aerosols in the matrix segment 10, allowing at least some aerosols to enter the groove 4, thereby improving aerosol extraction efficiency or aerosol release consistency. On the other hand, during the heating of the matrix segment 10, the aerosol-generating matrix is ​​gradually consumed, and the inner matrix 1 and outer layer 2 gradually shrink. The shrinkage rates of the inner matrix 1 and outer layer 2 differ at each location. For example, if the inner matrix 1 is heated first, followed by the outer layer 2, the area of ​​the first circumferential surface 1a located in the groove 4 shrinks more slowly than the surrounding area. This allows the corresponding area of ​​the second circumferential surface 2a to quickly contact the groove 4, and the groove 4 and the corresponding area provide a stop-fitting fit, ensuring that the inner matrix 1 and outer layer 2 maintain good connection strength during the heating of the matrix segment 10.

[0119] It is understandable that, based on the foregoing, when heating the outer layer 2 first and then the inner substrate 1, the second circumferential surface 2a may have a groove 4, while the first circumferential surface 1a may not have a groove 4. When heating the inner substrate 1 and the outer layer 2 simultaneously, both the first circumferential surface 1a and the second circumferential surface 2a may have grooves 4. This ensures that the inner substrate 1 and the outer layer 2 maintain good bonding strength during the heating of the substrate segment 10.

[0120] In one embodiment, the first circumferential surface 1a has a groove 4, while the second circumferential surface 2a does not have a groove 4. The area of ​​the first circumferential surface 1a other than the groove 4 abuts against the corresponding area of ​​the second circumferential surface 2a. In another embodiment, the second circumferential surface 2a has a groove 4, while the first circumferential surface 1a does not have a groove 4. The area of ​​the second circumferential surface 2a other than the groove 4 abuts against the corresponding area of ​​the second circumferential surface 2a. In yet another embodiment, both the first circumferential surface 1a and the second circumferential surface 2a have grooves 4, and the areas of both abut against each other, excluding the groove 4.

[0121] In some embodiments, please refer to Figures 12 to 14 The groove 4 extends in a straight line along the first direction. This not only facilitates design and production, but also allows the aerosol to maintain a relatively straight flow, increasing the flow rate of the aerosol and enabling users to draw in the aerosol more quickly.

[0122] In some embodiments, please refer to Figure 12 and Figure 13 The groove 4 penetrates at least one end face of the article segment 1000 along the first direction. For example, the article segment 1000 has a distal lip end and a proximal lip end in the first direction, allowing aerosol to flow from the distal lip end along the groove 4 to the proximal lip end. This enables orderly delivery of the aerosol, resulting in lower flow resistance and better controllability.

[0123] In one embodiment, the groove 4 penetrates the distal lip end face of the article segment 1000 along the first direction. In another embodiment, the groove 4 penetrates the proximal lip end face of the article segment 1000 along the first direction. In yet another embodiment, the groove 4 penetrates both the distal lip end face and the proximal lip end face of the article segment 1000 along the first direction.

[0124] Taking the substrate segment 10 as an example, where the product segment 1000 is used and the groove 4 penetrates the near-lip end face of the substrate segment 10 along the first direction, during the heating of the substrate segment 10, the near-lip end of the substrate segment 10 is closer to the user's mouth. In this way, the aerosol can flow smoothly into the user's mouth, making it easier for the user to inhale.

[0125] Taking the matrix segment 10 as an example, where the product segment 1000 is used and the groove 4 penetrates the distal and proximal lip ends of the matrix segment 10 along the first direction, that is, the inner matrix 1, the outer jacket 2, and the groove 4 have the same length along the first direction. This not only facilitates the manufacturing of the matrix segment 10 and improves production efficiency, but also allows for smoother aerosol flow. Furthermore, when the inner matrix 1 and the outer jacket 2 shrink, it is ensured that the first circumferential surface 1a and the second circumferential surface 2a are in a stop-and-go fit at all points.

[0126] In some embodiments, please refer to Figure 12 and Figure 14 Both the first circumferential surface 1a and the second circumferential surface 2a are provided with grooves 4, and the grooves 4 of the first circumferential surface 1a and the second circumferential surface 2a are spaced apart along the circumferential direction. That is to say, the grooves 4 of the first circumferential surface 1a and the grooves 4 of the second circumferential surface 2a are distributed at intervals around the first direction.

[0127] In this way, on the one hand, the grooves 4 of the first circumferential surface 1a and the second circumferential surface 2a can form multiple air channels for aerosol flow, thereby guiding the aerosol to flow in a predetermined direction, reducing airflow turbulence, and improving aerosol flow efficiency. It also helps to ensure uniform release of aerosol within the product section 1000, avoiding excessively high or low local aerosol concentrations that could affect the user's suction experience. On the other hand, it prevents the areas of the first circumferential surface 1a and the second circumferential surface 2a located in the grooves 4 from overlapping, which would result in an excessively large gap between them. This would prevent the first circumferential surface 1a and the second circumferential surface 2a from properly engaging in this area when the inner matrix 1 and the outer jacket 2 shrink, thus affecting the overall connection strength of the product section 1000.

[0128] In some embodiments, please refer to Figures 12 to 15 The groove 4 is at least one. For example, the first circumferential surface 1a has at least one groove 4, while the second circumferential surface 2a does not have a groove 4. Another example is that the second circumferential surface 2a has at least one groove 4, while the first circumferential surface 1a does not have a groove 4. Yet another example is that the first circumferential surface 1a has at least one groove 4, and the second circumferential surface 2a has at least one groove 4. By changing the position and number of grooves 4, the product segment 1000 can be adapted to aerosol generation products 100 with different requirements.

[0129] It should be noted that the number of grooves 4 on the first circumferential surface 1a and the number of grooves 4 on the second circumferential surface 2a may be the same or different. The embodiments of this application do not limit the quantitative relationship between the two.

[0130] In some embodiments, please refer to Figures 12 to 15There are multiple grooves 4, which are evenly spaced circumferentially. That is, the distance between any two adjacent grooves 4 is equal. This ensures that the aerosol is evenly dispersed within each groove 4, further preventing excessively high or low local aerosol concentrations that could affect the user's suction experience. Furthermore, when the matrix section 10 uses the product section 1000, it helps maintain the structural stability of the matrix section 10, ensuring that the shrinkage rates of the inner matrix 1 and the outer jacket 2 are relatively uniform during the heating process, preventing deformation of the grooves 4 that could lead to blockage.

[0131] For example, the first circumferential surface 1a has multiple grooves 4, and the spacing between any two adjacent grooves 4 on the first circumferential surface 1a is the same. For example, the second circumferential surface 2a has multiple grooves 4, and the spacing between any two adjacent grooves 4 on the second circumferential surface 2a is the same.

[0132] In some embodiments, there are multiple grooves 4 on the first circumferential surface 1a and multiple grooves 4 on the second circumferential surface 2a, and the multiple grooves 4 on the first circumferential surface 1a and the multiple grooves 4 on the second circumferential surface 2a are evenly spaced along the circumference.

[0133] In one embodiment, at least one groove 4 of a second circumferential surface 2a is provided between any two adjacent grooves 4 of the first circumferential surface 1a.

[0134] In another embodiment, at least one groove 4 of the first circumferential surface 1a is provided between any two adjacent grooves 4 of the second circumferential surface 2a.

[0135] In another embodiment, the grooves 4 of all the first circumferential surfaces 1a are located in the first region of the product segment 1000 along the circumferential direction, and the grooves 4 of all the second circumferential surfaces 2a are located in the second region of the product segment 1000 along the circumferential direction.

[0136] In another embodiment, all the grooves 4 of the first circumferential surface 1a and all the grooves 4 of the second circumferential surface 2a are mirror-symmetrical about the central axis of the product segment 1000.

[0137] In some embodiments, please refer to Figures 12 to 15 The groove 4 located on the first circumferential surface 1a is an inner groove 41, and the groove 4 located on the second circumferential surface 2a is an outer groove 42. Multiple inner grooves 41 and multiple outer grooves 42 are distributed alternately along the circumference. That is, an outer groove 42 is provided between any two adjacent inner grooves 41, and an inner groove 41 is provided between any two adjacent outer grooves 42.

[0138] In one embodiment, a plurality of inner grooves 41 and a plurality of outer grooves 42 are evenly and alternately distributed along the circumference. That is, the distance between any two adjacent inner grooves 41 is equal to the distance between any two adjacent outer grooves 42. Thus, during the production process, the plurality of inner grooves 41 and the plurality of outer grooves 42 can be arranged on the first circumferential surface 1a and the second circumferential surface 2a respectively using the same design, reducing manufacturing difficulty. During the installation process, for example, aligning any one inner groove 41 with the center position between two outer grooves 42 can achieve the positioning of other grooves, thereby facilitating the connection between the inner substrate 1 and the outer sleeve 2, reducing installation difficulty, significantly improving production efficiency, and enabling a more precise fit between the inner substrate 1 and the outer sleeve 2.

[0139] In some embodiments, the first circumferential surface 1a has 1 to 36 grooves 4. For example, the number of grooves 4 on the first circumferential surface 1a can be 1, 2, 4, 8, 16, 32 or 36, etc. By setting an appropriate number of grooves 4, not only can the flow efficiency of the aerosol be improved, allowing users to inhale a rich-tasting aerosol, but the structure of the inner matrix 1 can also be prevented from becoming complicated.

[0140] In some embodiments, the second circumferential surface 2a has 1 to 36 grooves 4. For example, the number of grooves 4 on the second circumferential surface 2a can be 1, 2, 4, 8, 16, 32 or 36, etc. By setting an appropriate number of grooves 4, not only can the flow efficiency of the aerosol be improved, allowing users to inhale a rich-tasting aerosol, but the structure of the inner matrix 1 can also be prevented from becoming complicated.

[0141] In some embodiments, the first circumferential surface 1a has 1 to 36 grooves 4, and the second circumferential surface 2a has 1 to 36 grooves 4. That is, the article segment 1000 includes between 2 and 72 grooves 4.

[0142] In other embodiments, the first circumferential surface 1a and the second circumferential surface 2a together have 1 to 36 grooves 4.

[0143] In some embodiments, please refer to Figure 15 The projection plane is a plane perpendicular to the first direction. The projection shape of the groove 4 is any one of the following: arc, quadrilateral, dovetail, sawtooth, or irregular shape.

[0144] In one embodiment, please refer to Figure 13 and Figure 15 The groove 4 is arc-shaped. This not only reduces manufacturing difficulty, but the arc-shaped groove 4 can also guide the flow of aerosols more smoothly.

[0145] For example, the grooves 4 of both the first circumferential surface 1a and the second circumferential surface 2a are arc-shaped.

[0146] In one embodiment, the groove 4 is quadrilateral. This provides a larger flow space, thereby increasing the aerosol release efficiency and resulting in a richer flavor from the aerosol inhaled by the user.

[0147] For example, the grooves 4 of both the first circumferential surface 1a and the second circumferential surface 2a are quadrilateral.

[0148] In one embodiment, the groove 4 is dovetail-shaped. This dovetail-shaped groove 4 provides better stability and prevents deformation and blockage during the heating of the substrate section 10.

[0149] For example, the protrusions 3 on both the first circumferential surface 1a and the second circumferential surface 2a are dovetail-shaped.

[0150] In one embodiment, the groove 4 is serrated. For example, the groove 4 of both the first circumferential surface 1a and the second circumferential surface 2a is serrated.

[0151] In one embodiment, the groove 4 is irregularly shaped. This allows for customization to meet different needs and achieve specific functions, such as optimizing heat transfer paths or improving aerosol flow paths.

[0152] In this embodiment, by setting a suitable groove 4 shape, the overall connection strength of the product segment 1000 and the need to achieve different functions can be taken into account.

[0153] It should be noted that the specific shape of the groove 4 is not limited in the embodiments of this application. The groove 4 can also be any other shape, such as a teardrop shape or an ellipse, etc., which will not be elaborated here.

[0154] In some embodiments, please refer to Figure 5 and Figure 6 One of the first circumferential surface 1a and the second circumferential surface 2a is provided with a protrusion 3, and the other of the first circumferential surface 1a and the second circumferential surface 2a is provided with a groove 4. The protrusion 3 abuts against the groove wall surface of the groove 4. That is to say, the protrusion 3 and the corresponding groove 4 have the same shape, and the protrusion 3 is embedded in the groove 4. Through the cooperation of the protrusion 3 and the groove 4, on the one hand, the inner substrate 1 and the outer sleeve 2 can be accurately positioned during assembly, and the relative rotation or misalignment of the inner substrate 1 and the outer sleeve 2 can be prevented. On the other hand, the protrusion 3 and the groove 4 can increase the contact area of ​​the first circumferential surface 1a and the second circumferential surface 2a, thereby enhancing the connection stability of the inner substrate 1 and the outer sleeve 2 and improving the overall connection strength of the product segment 1000. Furthermore, the protrusion 3 and the groove 4 also serve a positioning function, facilitating the loading and unloading of the inner substrate 1 and the outer sleeve 2.

[0155] In one embodiment, please refer to Figure 5and Figure 6 The first circumferential surface 1a has at least one protrusion 3, and the second circumferential surface 2a has at least one groove 4. In another embodiment, the first circumferential surface 1a has at least one groove 4, and the second circumferential surface 2a has at least one protrusion 3.

[0156] In some embodiments, please refer to Figure 6 There are multiple protrusions 3 and grooves 4, and each protrusion 3 has a corresponding groove 4. That is to say, the number of protrusions 3 and grooves 4 is the same.

[0157] For example, if the first circumferential surface 1a has multiple protrusions 3, then the second circumferential surface 2a has multiple corresponding grooves 4. Similarly, if the first circumferential surface 1a has multiple grooves 4, then the second circumferential surface 2a has multiple corresponding grooves 4. Furthermore, if the first circumferential surface 1a has multiple protrusions 3 and multiple grooves 4, then the second circumferential surface 2a has multiple corresponding grooves 4 and multiple protrusions 3, and vice versa. The embodiments of this application do not limit the specific number or distribution of the protrusions 3 and grooves 4.

[0158] In some embodiments, the inner matrix 1 and the outer layer 2 are co-extruded. Extrusion molding refers to a process in which material is pushed by the screw through the action between the extruder barrel and the screw, and continuously passed through the die head to form products or semi-finished products of various cross-sections. That is, the inner matrix 1 and the outer layer 2 are simultaneously manufactured by extrusion molding. Co-extrusion molding of the inner matrix 1 and the outer layer 2 allows for the mass production of 1000 product segments, improving production efficiency and reducing production costs.

[0159] Please see Figure 16 This application also provides an aerosol generating article 100, including the article segment 1000 in any embodiment of this application.

[0160] For example, please refer to 16. The aerosol generating article 100 includes a plurality of article segments 1000, one of which is a matrix segment 10 and the remaining article segments 1000 are functional segments 20. The matrix segment 10 and the functional segments 20 are arranged along a first direction.

[0161] In one embodiment, there are multiple functional segments 20, and at least one functional segment 20 uses a workpiece segment 1000. Taking three functional segments 20 as an example, one functional segment 20 may use a workpiece segment 1000, while the other two functional segments 20 may not use a workpiece segment 1000. Alternatively, two functional segments 20 may use a workpiece segment 1000, while the other functional segment 20 may not use a workpiece segment 1000. Furthermore, all three functional segments 20 may use a workpiece segment 1000.

[0162] This application does not specifically limit the material of functional segment 20. In one embodiment, functional segment 20 includes a skeleton component and an adhesive component. The skeleton component provides a skeleton for functional segment 20 to facilitate molding, and the adhesive is used to wet and closely contact the interfaces of the various components in functional segment 20, thereby bonding the powders, liquids, etc. of the various components. Exemplarily, the skeleton component includes one or more of calcium carbonate, talc, kaolin, diatomaceous earth, cellulose, hemicellulose and lignin, tobacco raw materials, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants; the adhesive component includes one or more of xanthan gum, sodium alginate, pullulan, tamarind polysaccharide, guar gum, and modified cellulose, wherein the modified cellulose is selected from one or more of sodium carboxymethyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, and hydroxypropyl cellulose.

[0163] For example, please refer to Figure 16 Functional segment 20 includes support segment 21. In one embodiment, support segment 21 is a workpiece segment 1000.

[0164] For example, please refer to Figure 16 Functional section 20 includes a cooling section 22, which is used to reduce the temperature of the aerosol. This makes the aerosol suitable for user inhalation. In one embodiment, the cooling section 22 is a product section 1000.

[0165] For example, please refer to Figure 16 Functional segment 20 includes a filter segment 23 for filtering aerosols. Exemplarily, filter segment 23 can block substances of a target particle size and can also adjust the suction resistance. For example, filter segment 23 can filter large-diameter particles, similar to powdery substances. Aerosols filtered through filter segment 23 have a higher particle size uniformity and a smoother texture. In one embodiment, filter segment 23 is a product segment 1000.

[0166] The cooling section 22 and the filter section 23 can be made of the same material or different materials.

[0167] For example, please refer to Figure 16 Functional segment 20 includes a pre-plug segment 24, which seals the distal lip of matrix segment 10 to prevent aerosol backflow, allowing the user to smoothly draw in the aerosol. In one embodiment, the pre-plug segment 24 is a product segment 1000.

[0168] In one embodiment, please refer to Figure 16 The fore plug section 24, the matrix section 10, the support section 21, the cooling section 22, and the filter section 23 are connected sequentially along the first direction.

[0169] In some embodiments, the front plug section 24, the cooling section 22, and the support section 21 can all be integrally formed structures. For example, the front plug section 24, the cooling section 22, and the support section 21 can all be integrally formed using processes such as injection molding, die casting, or extrusion.

[0170] In one embodiment, the aerosol generating article 100 includes a coating layer that covers the outer periphery of the matrix section 10 and the outer periphery of the functional section 20. Exemplarily, the coating layer covers the outer peripheral surfaces of the matrix section 10 and the functional section 20. That is, the outer peripheries of the front plug section 24, the matrix section 10, the support section 21, the cooling section 22, and the filter section 23 are all covered by the coating layer. The coating layer can be a single layer, or two or more layers can be designed according to the design requirements and manufacturing process of the aerosol generating article 100. For example, during manufacturing, the support section 21, the cooling section 22, and the filter section 23 can be first wrapped with a single coating layer, and then another coating layer can be used to wrap the matrix section 10 and the front plug section 24. Other combinations are also possible.

[0171] For example, the encapsulation layer is formed with side holes for introducing external gases, such as air, into the interior of the aerosol generating article 100 to maintain the air pressure balance inside the aerosol generating article 100.

[0172] In one embodiment, the matrix segment 10 includes plant materials, auxiliary materials, smoke-generating agent materials, adhesive materials, and fragrance materials. That is, the inner matrix 1 and the outer layer 2 may include plant materials, auxiliary materials, smoke-generating agent materials, adhesive materials, and fragrance materials.

[0173] Plant-based ingredients are used to generate aerosols upon heating. Additive ingredients provide skeletal support for the plant-based ingredients. Smoke-generating ingredients produce a large amount of smoke upon heating. Binder ingredients bind the component ingredients together. Fragrance ingredients provide characteristic aromas. Thus, the plant-based and smoke-generating ingredients ensure sufficient aerosol generation, while the fragrance ingredients enhance aroma release during inhalation, improving the user experience. Additive ingredients not only improve the flowability of the mixture but also create a porous structure in the matrix segment 10, facilitating aerosol extraction and flow. Binder ingredients ensure a stable mixture of plant-based powder and additives, preventing a loose structure.

[0174] In one embodiment, the plant-based raw materials are one or more combinations of tobacco leaves, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants, which are powdered after being crushed. The plant-based raw materials are the core source of the aroma, and the endogenous substances in them can provide users with physiological satisfaction. Endogenous substances, such as alkaloids, enter the bloodstream and promote the pituitary gland to produce dopamine, thereby achieving physiological satisfaction.

[0175] In one embodiment, the auxiliary raw material can be one or more combinations of inorganic fillers, lubricants, and emulsifiers. The inorganic fillers include one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. The inorganic fillers can provide skeletal support for the plant material, and also have micropores, which can increase the porosity of the matrix segment 10, thereby increasing the aerosol release rate.

[0176] Lubricants include one or more of the following: candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. Lubricants can increase the flowability of plant-based powders, reduce friction between powder particles, resulting in a more uniform overall density of the powder. They can also reduce the pressure required during extrusion molding and decrease die wear.

[0177] Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers can, to some extent, slow down the loss of aroma compounds during storage, increase their stability, and improve the sensory quality of the product.

[0178] In one embodiment, the smoke-generating agent raw material may include one or more combinations of: monohydric alcohol (such as menthol); polyhydric alcohol (such as propylene glycol, glycerol, triethylene glycol, 1,3-butanediol, and tetraethylene glycol); esters of polyhydric alcohols (such as triacetin, triethyl citrate, a mixture of diacetin, triethyl citrate, methyl benzoate, and triglyceride); monocarboxylic acid; dicarboxylic acid; polycarboxylic acid (such as lauric acid and myristic acid) or aliphatic esters of polycarboxylic acids (such as dimethyl dodecanoate, dimethyl tetradecanoate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl lauryl carbonate, triacetin, mesoerythritol, a mixture of diacetin, diethyl octanoate, triethyl citrate, methyl benzoate, phenylacetic acid, ethyl vanillate, triglyceride, and lauryl acetate).

[0179] In one embodiment, the adhesive raw material achieves close contact with the component raw material through interfacial wetting, generating intermolecular attraction and thus serving to bind the component raw materials, such as powders and liquids. The adhesive raw material can be one or more combinations of natural plant extracts and non-ionic modified viscous polysaccharides, including tamarind polysaccharide, guar gum, and modified cellulose (such as carboxymethyl cellulose). The adhesive is used to bond particles together, preventing them from easily falling apart, and also improves the water resistance of the matrix segment 10, while being harmless to the human body.

[0180] In one embodiment, the flavoring ingredient is used to provide characteristic aromas, such as hay, roasted sweetness, or solid or liquid substances of nicotine.
