Description

Technical Field

[0001] This application relates to the field of smoke-generating products, and more particularly to an aerosol-generating product. Background Technology

[0002] In related technologies, aerosol generating products generally generate aerosols by heating without combustion. Specifically, aerosol generating products use an external heat source to heat the aerosol generating matrix in the aerosol generating product to generate aerosols. The aerosol generating matrix does not burn, but instead loads a smoke-generating agent. When used, the smoke-generating agent is released by heating to form smoke.

[0003] During inhalation, the aroma release of the aerosol-generated product is not stable enough, which is detrimental to the consistency of the aerosol-generated product and affects the user's inhalation experience. Summary of the Invention

[0004] In view of this, the embodiments of this application aim to provide an aerosol-generated product with good fragrance carrying and retention capabilities, good consistency, and improved user inhalation experience.

[0005] This application provides an aerosol generating article, comprising a filter section, a first functional section, a matrix section, and a second functional section arranged sequentially along a first direction. The filter section has a greater absorption resistance than the first functional section. The matrix section is used to generate aerosols. The first functional section and / or the second functional section is an integral structure containing a fragrance substance.

[0006] In some embodiments, the components of the first functional segment and / or the second functional segment include plant components, smoke generators, binders, and feature providers for providing the fragrance substance.

[0007] In some embodiments, the aerosol generating article includes an encapsulation layer covering the periphery of the filter section, the first functional section, the matrix section, and the second functional section;

[0008] The encapsulation layer has a first through hole at the outer periphery of the first functional segment; the first functional segment has an air intake channel, a first central air channel and a first side air channel, the air intake channel connects the first through hole and the first central air channel, the first side air channel connects the air intake channel and the matrix segment, and the first central air channel penetrates the end faces of the first functional segment at opposite ends in the first direction.

[0009] In some embodiments, the first side airway extends through the end faces of the first functional segment at opposite ends in the first direction.

[0010] In some embodiments, the cross-sectional area of ​​the first central airway is 0.19 mm.2 ~28.3mm 2 .

[0011] In some embodiments, the number of first side airways is one or more, and the side length or diameter of the cross-sectional pattern of each first side airway is 0.1 mm to 5 mm.

[0012] In some embodiments, the number of the first through holes is 1 to 25;

[0013] The distance between each first through hole and the near-lip edge of the wrapping layer is 7 mm to 30 mm; and / or, the dimension of each first through hole along the circumferential direction of the wrapping layer is 0.1 mm to 1.0 mm.

[0014] In some embodiments, the ratio of the length of the first functional segment along the first direction to the length of the matrix segment along the first direction is 1 to 3.

[0015] In some embodiments, the matrix segment comprises an aerosol-generating matrix with a packing density of 0.3 g / mm². 3 ~0.6g / mm 3 ; and / or,

[0016] The ratio of the length of the matrix segment along the first direction to the total length of the aerosol-generated product extending along the first direction is not less than 20%.

[0017] In some embodiments, the ratio of the length of the second functional segment in the first direction to the perimeter of the second functional segment is not less than 15.9%.

[0018] In some embodiments, the second functional segment is provided with a central channel and an air passage, both of which penetrate the end faces of the second functional segment at opposite ends in the first direction.

[0019] The aerosol-generated articles provided in this application are made by molding the first and / or second functional segments into an integrated structure. The components have more choices during the development process, and fragrance substances can be added during the production stage. The fragrance substances are added as raw materials and recombined with the other components. The fragrance carrying capacity and fragrance types of the structure obtained in this way far exceed those of traditional fragrance carrying materials (such as cellulose acetate rods or paper filter rods). This can enhance the fragrance carrying and retention capacity of the first and / or second functional segments. In addition, the components in the integrated structure are more stable, which is conducive to the stable and slow release of fragrance. Whether it is set at the near-lip end or the far-lip end of the matrix segment, it is beneficial to improve the flavor richness and consistency of the aerosol-generated articles.

[0020] Both the first and second functional sections are integrated structures containing fragrance, which not only enhance the flavor richness and consistency of aerosol-generated products as mentioned above, but also simplify the process of aerosol-generated products, shorten the process flow, and help reduce costs.

[0028] 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.

[0032] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example that is included in at least one embodiment or example of the embodiments of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0033] This application provides an aerosol generating article 100. The aerosol generating article 100 can be used with an electronic atomizing device. For example, the aerosol generating article 100 is inserted into the electronic atomizing device, and the heat source in the electronic atomizing device heats the aerosol generating article 100 to generate an aerosol for the user to inhale.

[0034] Please see Figures 1 to 4 The aerosol generating article 100 includes a filter section 10, a first functional section 21, a matrix section 30, and a second functional section 22 arranged sequentially along a first direction. The first direction can be referred to as... Figure 1 and Figure 3 The direction indicated by the middle arrow. The two ends along the first direction of the aerosol-generated article 100 are respectively regarded as the proximal lip end Q1 and the distal lip end Q2.

[0035] The filter section 10 is located at the end of the first functional section 21 away from the matrix section 30 along the first direction, and the suction resistance of the filter section 10 is greater than that of the first functional section 21. The matrix section 30 is used to generate aerosols, and the filter section 10 is used to filter and adsorb the aerosols, thereby improving the purity and comfort of the aerosols.

[0036] For example, the material of the filter section 10 may be one or more of the following: cellulose acetate, polyethylene terephthalate, cellulose paper filter rod, polypropylene fiber, reconstituted tobacco, polylactic acid fiber, resin, plant polysaccharides, etc.

[0037] Understandably, the first functional segment 21 is located near the lip end of the matrix segment 30 and can play a role including reducing the temperature of the aerosol; the second functional segment 22 is located at the distal lip end of the matrix segment 30 and can play a role including reducing the loss of material from the matrix segment 30 during storage, transportation or suction.

[0038] For example, the matrix segment 30 includes an aerosol generating matrix, which can be a tobacco-containing material such as filaments, flakes, thin sheets, granules, or columns, or other plant materials other than tobacco. When heated by an external heat source, the matrix segment 30 generates aerosols.

[0039] For example, the matrix segment 30 also includes a smoke-generating agent. The smoke-generating agent functions to generate a large amount of vapor upon heating, thereby increasing the amount of smoke produced by the aerosol-generating article 100. For example, the smoke-generating agent may include one or more combinations of monohydric alcohols (such as menthol), polyhydric alcohols (such as propylene glycol, triethylene glycol, 1,3-butanediol, and glycerol), polyhydric alcohol esters (such as glyceryl monoacetate, glyceryl diacetate, or glyceryl triacetate), monocarboxylic acids, polycarboxylic acids (such as lauric acid, 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 acetate, triactin, meso erythritol, a mixture of diacetic acid esters, diethyl caprylate, triethyl citrate, methyl benzoate, phenylacetic acid methyl ester, ethyl vanillate, glyceryl tributate, and lauryl acetate).

[0040] The first functional segment 21 and / or the second functional segment 22 are integral structures containing fragrance substances. That is to say, there are three situations: First, the first functional segment 21 is an integral structure containing fragrance substances; second, the second functional segment 22 is an integral structure containing fragrance substances; third, both the first functional segment 21 and the second functional segment 22 are integral structures containing fragrance substances.

[0041] It should be noted that in some embodiments, the first functional segment 21 is a one-piece structure and contains a fragrance substance, while the second functional segment 22 may be a one-piece structure without a fragrance substance. That is, the raw materials of the first functional segment 21 and the second functional segment 22 may be different, and at least one of them is a one-piece structure containing a fragrance substance. Similarly, in some embodiments, the second functional segment 22 is a one-piece structure and contains a fragrance substance, while the first functional segment 21 may be a one-piece structure without a fragrance substance.

[0042] The aforementioned one-piece structure refers to a structure formed through a one-piece molding process, such as extrusion, injection molding, die casting, or 3D printing. This one-piece structure contains flavoring substances, meaning the raw materials used in the process include flavoring agents. These flavoring agents provide fragrance, allowing users to choose different flavors and enjoy a richer and more diverse smoking experience.

[0043] In related technologies, functional sections consisting of cellulose acetate rods or paper filters are set at both ends of the matrix section. Because they are close to the heated matrix section, the cellulose acetate rods or paper filters are easily heated and produce a sour taste or papery smell, which affects the smoking experience. In addition, the fragrance carrying and retention capacity of cellulose acetate rods and paper filters is limited, the fragrance decays quickly, and the consistency of aerosol products is poor.

[0044] The aerosol-generating product 100 provided in this application embodiment, by mixing and molding to form an integral structure of the first functional segment 21 and / or the second functional segment 22, has more choices of components during the development process. Fragrance substances can also be added during the production stage. The fragrance substances are added as raw materials and recombined with the other components. The fragrance carrying capacity and fragrance types of the structure obtained in this way far exceed those of traditional fragrance carrying materials (acetic acid cellulose rods or paper filter rods, etc.), which can enhance the fragrance carrying and retention capacity of the first functional segment 21 and / or the second functional segment 22. In addition, the components in the integral structure are more stable, which is conducive to the stable and slow release of fragrance. Whether it is set at the near-lip end or the far-lip end of the matrix segment 30, it is beneficial to improve the flavor richness and consistency of the aerosol-generating product 100.

[0045] Both the first functional section 21 and the second functional section 22 are integrated structures containing fragrance. They can not only enhance the flavor richness and consistency of the aerosol-generated product 100 as mentioned above, but also simplify the process of the aerosol-generated product 100, shorten its process flow, and help reduce costs.

[0046] For example, the first functional segment 21 and / or the second functional segment 22, which are integral structures containing flavoring substances, are extrusion structures. An extrusion structure is a structure processed through an extrusion molding process. Extrusion molding refers to a processing method in which a mixture is added to an extruder, and the mixture is pushed forward by the screw through the action between the extruder barrel and the screw, continuously passing through the die at the extruder outlet to form products or semi-finished products of various cross-sections. The products formed by extrusion molding have a strip-like structure. For example, the mixture is placed in a die, compacted, and extruded to form a continuously extending extrusion structure. The extrusion molding process corresponding to the extrusion structure has high production efficiency and high process precision, which helps to reduce the cost of aerosol-generated products 100 and reduce the defect rate.

[0047] It is understood that the first functional segment 21 and / or the second functional segment 22 can be extruded along the first direction.

[0048] It should be noted that the first functional segment 21 and / or the second functional segment 22 being extruded structures does not limit them to being made in one step by extrusion molding. In some embodiments, drying, cutting, punching and other processes can be performed after extrusion.

[0049] In some embodiments, the components of the first functional segment 21 and / or the second functional segment 22 include plant powder, a smoke generator, a binder, and a feature provider, the feature provider being used to provide a fragrance substance. In other words, if the first functional segment 21 and the second functional segment 22 are an integral structure containing a fragrance substance, it is referred to as functional segment 20, and the components of functional segment 20 include plant powder, a smoke generator, a binder, and a feature provider.

[0050] In this embodiment, the plant powder includes at least one of the roots, stems, leaves, flowers, and fruits of plants, which can be used as the substrate of the functional segment 20 to provide support and produce the plant's natural fragrance. The smoke generator can be glycerol, propylene glycol, etc., used to increase the amount of smoke generated by the aerosol product 100 and to lower the temperature of the aerosol while generating smoke. The binder includes at least one of sodium carboxymethyl cellulose, carrageenan, xanthan gum, guar gum, agar, gelatin, sodium alginate, locust bean gum, and konjac gum, used to bind the components together. The feature provider can be at least one of the following: plant extract, solanone, furanone, 2-acetylpyrazine, damasne, β-ionone, levulinic acid, menthol, menthone, menthone glyceryl ketal, peppermint oil, peppermint oil, ethyl butyrate, ethyl acetate, ethyl isovalerate, isoamyl acetate, peach aldehyde, methyl cinnamate, and methyl salicylate.

[0051] In this embodiment, functional segment 20 serves a supporting and cooling function. During the production of functional segment 20, the raw material formula is adjusted, and one or more characteristic suppliers and smoke generators are added. A single processing step completes the preparation and fragrance loading of functional segment 20, simplifying the production process and allowing for flexible adjustment of the taste and aroma of the aerosol-generated product 100, enhancing its flavor richness and smoke volume during inhalation. Before the functional segment 20 is formed, the plant raw materials are crushed into powder, and the characteristic suppliers or smoke generators are added to the plant powder and mixed evenly. Under the action of molding pressure and the binder, the plant powder, smoke generator, and characteristic suppliers form a dense and compact structure, ensuring stable aroma substances that are not easily volatilized and whose aroma does not easily diminish, giving functional segment 20 excellent fragrance loading and preservation functions. During inhalation, the natural aroma of the plant raw materials, aroma substances, and smoke generators in functional segment 20 are released slowly and stably upon heating, improving the consistency of the aerosol-generated product 100 during inhalation.

[0052] In some embodiments, please refer to Figure 1 and Figure 3 The aerosol generating article 100 includes a coating layer 50, which covers the outer periphery of the filter section 10, the first functional section 21, the matrix section 30, and the second functional section 22. The coating layer 50 is used to protect the interior from external dust or microbial contamination during storage and transportation. It also provides structural support for the aerosol generating article 100, connecting the filter section 10, the first functional section 21, the matrix section 30, and the second functional section 22, and maintaining its structural shape stability.

[0053] The material of the wrapping layer 50 is not limited, and it can be one or more of plant fiber paper, aluminum foil or tin foil.

[0054] Please see Figure 1 and Figure 3 The encapsulation layer 50 has a first through hole 50a located on the outer periphery of the first functional segment 21. The first functional segment 21 has an air intake channel 21c, a first central air passage 21a, and a first side air passage 21b. The air intake channel 21c connects the first through hole 50a and the first central air passage 21a, and the first side air passage 21b connects the air intake channel 21c and the matrix segment 30. The first central channel 22a penetrates the end faces of the first functional segment 21 at opposite ends in a first direction.

[0055] During suction, external air is drawn into the air inlet channel 21c through the first through-hole 50a. Part of the air enters the first side airway 21b and flows along it towards the matrix section 30, extracting the aerosols generated in the matrix section 30. The extracted air then enters the first central airway 21a for user suction. Part of the air enters the first central airway 21a from the air inlet channel 21c and flows towards the lip end, creating a negative pressure on the lip end of the first central airway 21a. This negative pressure facilitates the extraction of aerosols from the matrix section 30 by the first side airway 21b. The arrangement of the first central airway 21a and the first side airway 21b improves aerosol extraction efficiency, enhances the stability and uniformity of aerosol extraction, provides a better user suction experience, and reduces the possibility of complete blockage of the aerosol flow path due to manufacturing errors in the aerosol-generated product 100, thus lowering the manufacturing precision requirements for the aerosol-generated product 100.

[0056] For example, the cross-sectional area of ​​the first central airway 21a is larger than the cross-sectional area of ​​the single first side airway 21b.

[0057] For example, the first central airway 21a is located in the middle of the cross-section of the first functional segment 21, and the number of first side airways 21b can be one, two or more.

[0058] In embodiments where there are multiple first side airways 21b, the multiple first side airways 21b can increase the flow rate of air through the first side airways 21b to the matrix segment 30, which not only improves the extraction efficiency of air from the aerosol generated by the matrix segment 30, but also makes the aerosol entering the user's mouth more uniform, thereby further improving the user's suction experience.

[0059] For example, multiple first side airways 21b can be centrally symmetrically distributed around the first central airway 21a. This can further improve the uniformity of the aerosol.

[0060] For example, the first central airway 21a and the first side airway 21b both extend along the first direction, and the air intake passage 21c extends perpendicular to the first direction.

[0061] In some embodiments, the first side air passage 21b penetrates the end faces of the first functional segment 21 at opposite ends in the first direction. That is, both the first side air passage 21b and the first central air passage 21a penetrate the first functional segment 21 along the first direction, making the cross-sections of the first functional segment 21 perpendicular to the first direction relatively similar at various positions, which is beneficial for molding, such as extrusion molding.

[0062] In addition, the user's suction action near the lips can create negative pressure near the lips of the first side airway 21b, which is conducive to the entry of external air into the first side airway 21b through the air intake channel 21c.

[0063] In some embodiments, the cross-sectional area A of the first central airway 21a is 0.19 mm. 2 (square millimeters) ~ 28.3mm 2 That is, 0.19mm. 2 ≤A≤28.3mm 2 The value of A can be 0.19mm. 2 28.3mm 2 And any value within the range. Within this range, it is more conducive to the extraction of aerosols and the release of plant aroma and fragrance substances. If the cross-sectional area A is below the minimum value of 0.19 mm in this range. 2 At that time, the cross-sectional area of ​​the first central airway 21a was too small, which was not conducive to aerosol extraction, and the amount of smoke generated by aerosol product 100 was too small; exceeding the maximum value of 28.3 mm in this range. 2 At that time, the effective cavity volume of the first functional segment 21 is too large, resulting in a hollow suction sensation, poor aerosol agglomeration, and high aerosol temperature, which affects the suction experience.

[0064] For example, the cross-sectional shape of the first central airway 21a is circular, and its diameter is 0.5 mm to 6 mm, or more specifically, its diameter is 2 mm to 5 mm, which improves the extraction of the aerosol and the release of plant fragrance and aroma substances.

[0065] Of course, the cross-sectional shape of the first central airway 21a can also be other shapes, such as a regular hexagon, a regular octagon, etc.

[0066] In some embodiments, there are multiple first side airways 21b, and the side length or diameter B of the cross-sectional pattern of each first side airway 21b is 0.1mm to 5mm. That is, 0.1mm ≤ B ≤ 5mm, and the value of B can be 0.1mm, 5mm, or any value within this range. When the cross-section is below the minimum value of 0.1mm, the cross-section of the first side airway 21b is too small, which is not conducive to aerosol extraction, increases suction resistance, and prevents the full release of plant fragrance and aroma substances; when it is above the maximum value of 5mm, the suction sensation is hollow, the aroma is not concentrated, and the aerosol is easy to burn the mouth. More specifically, the perimeter of the cross-sectional pattern of the first side airway 21b is 0.5mm to 2mm. Within this range, the user's suction experience is better.

[0067] The cross-sectional shape of the first side airway 21b is not limited, including but not limited to circular, fan-shaped, polygonal, etc. When the cross-sectional shape of the first side airway 21b is circular, its diameter B is 0.1mm to 5mm; when the cross-sectional shape of the first side airway 21b is fan-shaped or polygonal, its side length B is 0.1mm to 5mm.

[0068] For example, in some embodiments, the number of first through holes 50a is 1 to 25, including 1 and 25. Within this range, the total air intake of the first through holes 50a is sufficient and will not significantly affect the appearance or suction feel of the aerosol-generating article 100. The number of first through holes 50a may be the same as or different from the number of first side air passages 21b, and is not limited here.

[0069] For example, in some embodiments, the distance between the first through-hole 50a and the near-lip edge of the wrapping layer 50 is 7mm to 30mm, to ensure that after the external air enters the first central airway 21a, it has sufficient time to mix with the aerosol generated by the matrix section 30, and the first through-hole 50a is not easily blocked when the user inhales, facilitating air intake. Let C be the distance between any one of the first through-holes 50a and the near-lip edge of the wrapping layer 50, that is, 7mm≤C≤30mm. The value of C includes, but is not limited to, 7mm, 15mm, 20mm, 25mm, and 30mm. When there are multiple first through-holes 50a, the distance between all the first through-holes 50a and the near-lip edge of the wrapping layer 50 is 7mm to 30mm.

[0070] For example, in some embodiments, the dimension of each first through hole 50a along the circumferential direction of the wrapping layer 50 is 0.1mm to 1mm. Let D be the dimension of the first through hole 50a along the circumferential direction of the wrapping layer 50, that is, 0.1mm ≤ D ≤ 1mm, and the value of L includes, but is not limited to, 0.1mm, 0.5mm, 0.7mm, and 1mm. Within this range, the air intake of the first through hole 50a is sufficient, and it does not occupy a large size along the first direction.

[0071] The shape of the first through hole 50a is not limited; it can be one of the following: circular, elliptical, rectangular, or regular polygonal.

[0072] In some embodiments, the ratio of the length of the first functional segment 21 along the first direction to the length of the matrix segment 30 along the first direction is 1 to 3. That is, the length of the first functional segment 21 along the first direction is 1 to 3 times that of the matrix segment 30, including 1 to 3 times. If the ratio is greater than 3, the first functional segment 21 is too long, which significantly increases the interception effect of effective components of flue gas and increases material costs. If the ratio is less than 1, the first functional segment 21 is too short, contains less material, and has poor support and cooling effects.

[0073] In some embodiments, the packing density of the aerosol-generating matrix of the matrix segment 30 is 0.3 g / mm². 3 (grams per cubic millimeter) ~ 0.6 g / mm 3 That is, the packing density of the aerosol generation matrix can be 0.3 g / mm². 3 0.6g / mm 3And any value within the range. The fill density is less than the minimum value of 0.3 g / mm² within this range. 3 If the filling is not dense enough, the matrix segment 30 is prone to deformation or collapse. Furthermore, if the filling density is too low, user satisfaction will be reduced; a filling density greater than the maximum value of 0.6 g / mm² will also be negative. 3 At that time, the suction resistance of the matrix section 30 was too high, which affected the suction feeling. In addition, the filling density was too high, which was not conducive to heat transfer, and the aerosol-generated matrix may have insufficient carbonization.

[0074] In some embodiments, the length of the matrix segment 30 along the first direction accounts for at least 20% of the total length of the aerosol generating article 100 extending along the first direction; that is, the length of the matrix segment 30 accounts for 20% or more of the total length of the aerosol generating article 100. Thus, the matrix segment 30 can carry a larger amount of aerosol generating matrix, and the aerosol generating article 100 can be aspirated for a longer period, enhancing user satisfaction.

[0075] The second functional segment 22 enables the aerosol generating product 100 to be easy to clean or require no cleaning, allowing it to be removed without dropping impurities after use in the electronic atomizing device. In some embodiments, the second functional segment 22 located at the distal lip end can be a component made of one or more materials such as cellulose acetate, polyethylene terephthalate, cellulose paper filter rod, and plant polysaccharides for sealing purposes, and can be referred to as a sealing segment. Figure 1 As indicated by 40. In another embodiment, the second functional segment 22 is an integral structure containing a fragrance substance.

[0076] In some embodiments, the ratio of the length of the second functional segment 22 in the first direction to the perimeter of the second functional segment 22 is not less than 15.9%, that is, the ratio of length to perimeter is 15.9% or more. In this way, the second functional segment 22 is not too thin, has good structural strength, and can effectively seal the distal lip of the matrix segment 30.

[0077] For example, when the outer periphery of the second functional segment 22 is cylindrical, the ratio of the length of the second functional segment 22 along the first direction to the diameter of the second functional segment 22 is not less than 0.5.

[0078] In some embodiments, please refer to Figure 5 The second functional section 22 is provided with a central channel 22a and an air passage 22b, both of which penetrate the end faces of opposite ends of the second functional section 22 in the first direction. The structure of the second functional section 22 is relatively simple and convenient for molding, such as extrusion molding. The central air passage 22b serves as a channel through which the heating needle of the electronic atomizing device passes, and it also allows air to enter the distal lip of the aerosol-generating product 100, adjusting the suction resistance of the aerosol-generating product 100.

[0083] The filter section 10 has a length of 7 mm along the first direction, is made of polyethylene terephthalate, and has a suction resistance of 80 Pa.

[0084] The first functional section 21 has a length of 24 mm along the first direction and contains 36 first side airways 21b. The cross-sectional shape of the first side airways 21b is approximately trapezoidal (or fan-shaped), with the length of each side of the trapezoid ranging from 0.1 mm to 5 mm. A first central airway 21a, running along the first direction, is located in the center of the cross-section of the first functional section 21. The cross-section of the first central airway 21a is circular with a diameter of 3.0 mm. Figure 2 As shown, the 36 first side airways 21b are divided into 3 layers of 12 each. The 3 layers of first side airways 21b surround the periphery of the first central airway 21a in a ring shape, and the 12 first side airways 21b in each layer are evenly spaced around the periphery.

[0085] The components of the first functional segment 21 include plant powders (kudzu root powder, glutinous rice leaves, etc.), binders (sodium carboxymethyl cellulose, amylopectin, etc.), characteristic agents (menthol oil, ethyl butyrate, ethyl acetate, ethyl isovalerate, isoamyl acetate, peach aldehyde, methyl cinnamate, methyl salicylate, etc.), a smoke generator (glycerin), water, and other materials. The above raw materials are mixed evenly and then extruded using an extruder.

[0086] The substrate segment has a length of 12 mm along the first direction, and the aerosol-generating matrix of the substrate segment includes tobacco shreds with a filling density of 0.437 g / mm². 3 .
