Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and more particularly to a matrix segment and an aerosol generation product. 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] Aerosol generating articles include a matrix segment, which is used for heating to generate aerosols. In related technologies, the matrix segment includes multiple aerosol generating matrices. The mass-to-surface-area ratio of a single aerosol generating matrix is ​​relatively large, resulting in relatively low heating efficiency of the matrix segment and reducing the efficiency of aerosol release. Utility Model Content

[0004] In view of this, the embodiments of this application aim to provide a matrix segment and an aerosol-generating article that can improve the heating efficiency of the matrix segment.

[0005] A first aspect of this application provides a matrix segment comprising a plurality of matrix strips for generating aerosols, wherein the mass-to-surface area ratio of the matrix strips is less than 0.09 mg / mm². 2 .

[0006] In some embodiments, the ratio of the mass of the matrix strip to the surface area of ​​the matrix strip is less than 0.08 mg / mm². 2 .

[0007] In some embodiments, the matrix strip has a first cross-section, the ratio of the area of ​​the first cross-section to the perimeter of the first cross-section is not greater than 0.07 mm, and the first cross-section is perpendicular to the length direction of the matrix strip.

[0008] In some embodiments, the first cross section is at least one of a triangle, quadrilateral, circle, cross, serrated, and irregular shape.

[0009] In some embodiments, the first cross section is quadrilateral, the length of the first cross section is 0.5 mm to 1.5 mm, and the width of the first cross section is 0.05 mm to 0.15 mm.

[0010] In some embodiments, the ratio of the mass of the matrix strip to the surface area of ​​the matrix strip is not less than 0.01 mg / mm². 2 .

[0011] In some embodiments, the length of the substrate strip is not less than 3 mm.

[0012] In some embodiments, the matrix strip is an extruded structure.

[0013] In some embodiments, the density of the matrix strip is 1000 mg / cm³. 3 Up to 1500 mg / cm 3 .

[0014] In some embodiments, the density of the matrix segment is 300 mg / cm³. 3 Up to 1000 mg / cm 3 .

[0015] In some embodiments, the plurality of said matrix strips are arranged in an ordered or disordered manner.

[0016] In some embodiments, the matrix strip includes a smoke-generating agent component, which accounts for 2% to 30% of the total mass of the matrix strip.

[0017] A second aspect of this application provides an aerosol generating article comprising a matrix segment as described in any of the preceding claims and at least one functional segment, wherein the matrix segment and the functional segment are disposed along a first direction.

[0018] The matrix segment provided in this application has a mass-to-surface area ratio of less than 0.09 mg / mm². 2 In this way, the appropriate mass per unit surface area reduces the energy required to heat the substrate section, which is beneficial for heat transfer, thereby improving the heating efficiency of the substrate section, enhancing the consistency of aerosol release, improving aerosol quality, and enhancing the user experience.

[0034] 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.

[0035] In the description of the embodiments of this application, the "first direction" orientation or positional relationship is based on Figure 7 , Figure 8 The orientation or positional relationship shown, the orientation or positional relationship in the "length direction" is based on Figures 1 to 3 The orientation or positional relationship shown is for illustrative purposes only and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the embodiments of this application.

[0036] 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 term "first" is 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.

[0037] It should be noted that in this application, "multiple" refers to a quantity including two or more. "At least one" refers to a quantity including one or more.

[0038] In this application, the unit "mg / mm" is used. 2 "mg / cm²" means milligrams per square millimeter. The unit "mm" stands for millimeter. 3 "It is milligrams per cubic centimeter."

[0039] In related technologies, the ratio of the mass of the aerosol-generating matrix to its surface area is typically 0.09 mg / mm². 2 The applicant found that when the ratio of the mass of the aerosol-generating matrix to its surface area is within the above range, the higher the mass per unit surface area, the higher the energy required for heat transfer during heating, the lower the heating efficiency, which is not conducive to rapid preheating and the release of aerosols with high heat transfer and high burst.

[0040] Please see Figures 1 to 8 This application provides a matrix segment 1 comprising a plurality of matrix strips 11 for generating aerosols. The mass-to-surface area ratio of the matrix strips 11 is less than 0.09 mg / mm². 2 .

[0041] The matrix strip 11 can be two, three, four, or more.

[0042] Two matrix strips 11 may or may not be connected. Multiple matrix strips 11 can be constrained using a wrapping layer or an outer layer to maintain the overall state of the matrix segment 1.

[0043] The matrix strip 11 is suitable for generating aerosols by heating without ignition. That is, the matrix strip 11 can be heated below the ignition point to generate aerosols without burning during the aerosol generation process.

[0044] In other scenarios, the matrix strip 11 can also be used to generate aerosols by heating and ignition, that is, the matrix strip 11 reaches the ignition point and generates aerosols by combustion.

[0045] Please see Figures 1 to 3The matrix strip 11 is strip-shaped. Exemplarily, the length of the matrix strip 11 is not limited; it can be a long strip or a relatively short strip. This facilitates the filling of multiple matrix strips 11.

[0046] The surface area of ​​the matrix strip 11 refers to the total area covered by all the outer surfaces of the matrix strip 11, that is, the sum of the areas of all the surfaces of the matrix strip 11 that are in contact with the outside world.

[0047] The specific value of the ratio of the mass of the matrix strip 11 to its surface area is not limited. As an example, the ratio of the mass of the matrix strip 11 to its surface area can be 0.05 mg / mm². 2 0.06 mg / mm 2 0.07 mg / mm 2 0.08 mg / mm 2 and 0.089 mg / mm 2 The value between any one or any two values ​​in the range.

[0048] The matrix segment 1 provided in this embodiment has a mass-to-surface area ratio of less than 0.09 mg / mm². 2 In this way, the appropriate mass per unit surface area reduces the energy required to heat the substrate section 1, which is beneficial for heat transfer, thereby improving the heating efficiency of the substrate section 1, enhancing the consistency of aerosol release, improving aerosol quality, and enhancing the user experience.

[0049] Preferably, in some embodiments, the ratio of the mass of the matrix strip 11 to the surface area of ​​the matrix strip 11 is less than 0.08 mg / mm². 2 This allows for a further reduction in the energy required to heat substrate section 1, thereby improving the heating efficiency of substrate section 1.

[0050] In one embodiment, please refer to Figure 9 and Figure 10 The matrix strip 11 has a homogeneous tobacco structure. A homogeneous tobacco structure is a reconstituted tobacco product with roughly uniform quality, made by physically recombining natural tobacco raw materials such as tobacco leaves, stems, and dust with liquid raw materials. Thus, the matrix strip 11 exhibits good product consistency.

[0051] In some embodiments, please refer to Figures 1 to 4 The matrix strip 11 has a first cross section 11a, the ratio of the area of ​​the first cross section 11a to the perimeter of the first cross section 11a is not greater than 0.07 mm, and the first cross section 11a is perpendicular to the length direction of the matrix strip 11.

[0052] The first cross-section 11a is within the aforementioned range, ensuring that the ratio of the mass of the matrix strip 11 to the surface area of ​​the matrix strip 11 is less than 0.09 mg / mm². 2This ensures reliable product quality.

[0053] For example, the ratio of the area of ​​the first cross section 11a to the perimeter of the first cross section 11a can be any value among 0.03mm, 0.035mm, 0.04mm, 0.045mm, 0.05mm, 0.055mm, 0.06mm, 0.065mm and 0.07mm or a value within a range of any two values.

[0054] In some embodiments, please refer to Figures 1 to 4 The first cross-section 11a is at least one of a triangle, quadrilateral, circle, cross, serrated, and irregular shape. For example, the first cross-section 11a can be triangular; the first cross-section 11a can also be circular; the first cross-section 11a can also be irregular. Irregular shape refers to a symmetrical or asymmetrical shape other than those listed above; for example, the first cross-section 11a can be snowflake-shaped. Thus, different shapes of the first cross-section 11a can be used as needed to facilitate filling.

[0055] For example, please refer to Figure 1 The first section 11a can be quadrilateral.

[0056] For example, please refer to Figure 2 The first section 11a can also be cross-shaped.

[0057] For example, please refer to Figure 3 and Figure 4 The first section 11a can also be serrated.

[0058] In some embodiments, the first cross section 11a may be two, three, or more of the following shapes: triangle, quadrilateral, circle, cross, serrated, and irregular.

[0059] In one embodiment, the first cross-section 11a of all matrix strips 11 has the same shape.

[0060] In another embodiment, the shape of the first cross section 11a of at least one matrix strip 11 is different from the shape of the first cross section 11a of the other matrix strips 11.

[0061] In some embodiments, please refer to Figure 1 The first section 11a is quadrilateral, the length of the first section 11a is 0.5mm to 1.5mm, and the width of the first section 11a is 0.05mm to 0.15mm.

[0062] The dimensions of the first section 11a are within the aforementioned range, and the shape of the matrix strip 11 is basically the same as that of the shredded natural tobacco leaves. This not only prevents the matrix strip 11 from being overheated but also facilitates aerosol release. In this way, it ensures that the matrix strip 11 is heated evenly, the aerosol release is consistent, and the generation of aerosols with a burnt smell is prevented.

[0063] For example, the length of the first section 11a can be any value among 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm and 1.5mm or a value between any two values.

[0064] For example, the width of the first section 11a can be any value among 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, 0.11mm, 0.12mm, 0.13mm, 0.14mm and 0.15mm or a value between any two of these values.

[0065] For example, please refer to Figure 1 Taking the first cross section 11a as an example, the surface area of ​​the matrix strip 11 refers to the sum of the area of ​​the circumferential surface of the matrix strip 11 along the length direction and the area of ​​the two first cross sections 11a that are quadrilateral.

[0066] The matrix segment 1 provided in the application embodiments will be described in more detail below with reference to specific embodiments. This application provides three embodiments, please refer to Table 1.

[0067] Example 1, please refer to Figure 1 The first cross-section 11a is rectangular in shape, with a length of 0.5 mm to 1.5 mm and a width of 0.05 mm to 0.15 mm. Thus, the ratio of the area to the perimeter of the first cross-section 11a is no greater than 0.7 mm², thereby ensuring that the ratio of the mass to the surface area of ​​the matrix strip 11 is less than 0.09 mg / mm². 2 .

[0068] Example 2, please refer to Figure 2 The first cross section 11a is cross-shaped. It should be noted that in this embodiment, the cross shape is composed of two rectangles of the same size, each rectangle having a length of 0.5mm to 1.1mm and a width of 0.05mm to 0.15mm. Thus, the ratio of the area to the perimeter of the first cross section 11a is no greater than 0.7mm², thereby ensuring that the ratio of the mass to the surface area of ​​the matrix strip 11 is less than 0.09mg / mm². 2 .

[0069] Example 3, please refer to Figure 3 and Figure 4 The first cross-section 11a has a sawtooth shape. The sawtooth shape means that the shape of the first cross-section 11a roughly resembles a sine wave function, and the matrix strip 11 can have a wavy structure. It should be noted that in this embodiment, the length of the first cross-section 11a refers to the distance between the two farthest points of the sine wave function, that is, Figure 4 In the range shown by L, the width of the first section 11a refers to the distance between adjacent crests and troughs, that is, Figure 4 The range is shown in Figure W. The length of the first section 11a is 1 mm to 1.8 mm, and the width of the first section 11a is 0.1 mm to 0.42 mm. Thus, the ratio of the area to the perimeter of the first section 11a is not greater than 0.7 mm², thereby ensuring that the ratio of the mass to the surface area of ​​the matrix strip 11 is less than 0.09 mg / mm². 2 .

[0070] Table 1

[0071]

[0072] In some embodiments, the ratio of the mass of the matrix strip 11 to the surface area of ​​the matrix strip 11 is not less than 0.01 mg / mm². 2 In other words, the ratio of the mass of the matrix strip 11 to its surface area is greater than or equal to 0.01 mg / mm². 2 Less than 0.09 mg / mm 2 The ratio of the mass of the matrix strip 11 to its surface area is within the above-mentioned range, which not only facilitates the smooth transfer of heat, but also prevents the matrix strip 11 from having a loose structure, thus affecting the mechanical strength of the overall structure of the matrix segment 1.

[0073] For example, the ratio of the mass of the matrix strip 11 to the surface area of ​​the matrix strip 11 can be 0.01 mg / mm². 2 0.02 mg / mm 2 0.03 mg / mm 2 0.04 mg / mm 2 0.05 mg / mm 2 0.06 mg / mm 2 0.07 mg / mm 2 0.08 mg / mm 2 and 0.89 mg / mm 2 The value between any one or any two values ​​in the range.

[0074] In some embodiments, the length of the substrate strip 11 is not less than 3 mm.

[0075] For example, the length of the substrate strip 11 can be any value among 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm and 15mm or a value between any two of these values.

[0076] In some embodiments, please refer to Figure 9 and Figure 10 The matrix strip 11 is an extruded structure. Specifically, the slurry is molded into the matrix strip 11 through the outlet of the molding die under a set temperature and pressure. The shape of the first cross-section 11a of the extruded matrix strip 11 is approximately the same as or slightly different from the shape of the outlet.

[0077] In some embodiments, please refer to Figure 1 and Figure 2 The matrix strip 11 can be a linear strip structure that extends in a roughly straight line.

[0078] In some embodiments, please refer to Figure 3 and Figure 4 The matrix strip 11 can be a curved strip structure with at least one part bent.

[0079] Exemplarily, the extruder includes a barrel and a screw. A cavity for receiving slurry is formed inside the barrel. A forming die is disposed at the port of the barrel, and the screw is disposed inside the cavity. The screw extrudes and pushes the slurry inside the cavity. The slurry continuously passes through the outlet of the forming die to form a matrix strip 11 that extends generally in a straight line or is at least partially curved. Compared to shredded tobacco leaves 3, and reconstituted tobacco prepared by papermaking, slurry making, and roll forming methods, the slurry produced by extrusion molding can include granular substrates formed from pulverized tobacco raw materials such as tobacco leaves, stems, and dust. It does not require the sorting and processing of tobacco leaves and stems, and the requirements for tobacco leaves are relatively low. The slurry can also include other herbal raw materials besides tobacco raw materials, which can make full use of herbal raw materials such as tobacco raw materials, reduce waste of raw materials, and the extrusion molding process is simple and can reduce production costs.

[0080] In some embodiments, the matrix strip 11 has micropores, and at least a portion of the micropores of the matrix strip 11 are interconnected.

[0081] Multiple micropores are interconnected to form microchannels. This increases the porosity of the matrix strip 11, thereby improving the aerosol release rate. Furthermore, the microchannels can carry fragrance, increasing the fragrance loading capacity of the matrix segment 1 and ensuring uniform fragrance distribution and better retention, thus enhancing the aroma intensity and consistency of the aerosol inhaled by the user. For example, in the particle-bound matrix strip 11, the gaps between the particles constitute micropores. Exemplarily, the mixture used to prepare the matrix strip 11 is a granular material. The matrix strip 11, extruded from the mixture, has micropores. The cross-sectional area and length of the micropores are naturally formed through the extrusion process and the raw material components. The mixture expands after flowing out of the die from the extrusion chamber, forming the micropores.

[0082] As an example, the micropores of some of the matrix strips 11 are interconnected, or the micropores of all the matrix strips 11 are interconnected.

[0083] It should be noted that the microchannels described in this application are disordered, meaning they are difficult to generate in an orderly manner according to a design; in other words, the microchannels are generated randomly. All microchannels are pores in a microscopic sense, and their size is determined by the gaps between particles.

[0084] In some embodiments, the density of the matrix strip 11 is 1000 mg / cm³. 3 Up to 1500 mg / cm 3 .

[0085] The density of matrix strip 11 is less than 1000 mg / cm³. 3 Under certain conditions, overheating of the matrix strip 11 can easily occur, leading to an excessively rapid aerosol release rate and affecting the consistency of aerosol release. When the density of the matrix strip 11 exceeds 1500 mg / cm³... 3 In this case, the matrix strip 11 is too dense, which affects the heating efficiency of the matrix strip 11 and makes it difficult for aerosols to be released.

[0086] The density of the matrix strip 11 is within the above range, which can ensure that the amount and rate of aerosol release are basically the same each time, improve the consistency of aerosol release, and improve the user experience.

[0087] For example, the density of the matrix strip 11 may be 1000 mg / cm³. 3 1050mg / cm 3 1100mg / cm 3 1150mg / cm 3 1200mg / cm 3 1250mg / cm 3 1300mg / cm 3 1350mg / cm 31400mg / cm 3 1450mg / cm 3 and 1500mg / cm 3 The value between any one or any two values ​​in the range.

[0088] In some embodiments, the density of matrix segment 1 is 300 mg / cm³. 3 Up to 1000 mg / cm 3 .

[0089] The density of matrix segment 1 is less than 300 mg / cm³. 3 In cases where the density of matrix segment 1 is higher than 1000 mg / cm³, the higher porosity makes it easier to heat and generate a large amount of aerosols, resulting in an excessively rapid aerosol release rate and affecting the consistency of aerosol release. 3 In this case, the matrix segment 1 is too dense, resulting in a large absorption resistance in the matrix segment 1, making it difficult for aerosols to be released.

[0090] The density of matrix segment 1 is within the above range, which can ensure that the amount and rate of aerosol release are basically the same each time, improve the consistency of aerosol release, and improve the user experience.

[0091] For example, the density of matrix segment 1 may be 300 mg / cm³. 3 400mg / cm 3 500mg / cm 3 600mg / cm 3 700mg / cm 3 800mg / cm 3 900mg / cm 3 and 1000mg / cm 3 The value between any one or any two values ​​in the range.

[0092] In some embodiments, please refer to Figure 5 and Figure 6 Multiple matrix strips 11 are arranged in an orderly or disordered manner.

[0093] Ordered arrangement is the arrangement according to a set rule or sequence.

[0094] Please see Figure 5 The orderly arrangement of multiple matrix strips 11 means that the matrix strips 11 are arranged according to a set rule or sequence, and the position of each matrix strip 11 can be controlled to place the matrix strips 11 in the preset position as designed. In this way, the matrix strips 11 can be uniformly filled, which is beneficial to improving heating efficiency and the consistency of aerosol release.

[0095] Please see Figure 6Disordered arrangement refers to the arrangement without a set rule or order. In this way, the matrix strip 11 can be filled with one or more aerosol generating matrices of any shape, such as sheet matrix, filament matrix and particulate matrix. By making full use of the matrix strip 11 and other types of aerosol generating matrices, production costs can be reduced.

[0096] In one embodiment, please refer to Figure 6 The matrix strips 11 can be arranged in an ordered or disordered manner, and the aerosol generating matrix fills the gaps formed by the matrix strips 11. For example, the aerosol generating matrix fills the gaps formed by the matrix strips 11 in a disordered manner, and the position of the aerosol generating matrix is ​​random.

[0097] It should be noted that the sheet matrix is ​​made by processing natural plant materials such as original leaves and tobacco stems into reconstituted sheets. The processing methods include papermaking, slurry processing, or roll pressing.

[0098] Filamentous matrix is ​​made by cutting the original leaf and / or the above-mentioned thin-film matrix into filaments. For example, please refer to... Figure 10 The filamentous matrix includes shredded tobacco leaves 3, and the matrix strip 11 provided in this application can be blended with shredded tobacco leaves 3 to form matrix segment 1.

[0099] Granular matrix is ​​made by pulverizing the original leaf and / or the aforementioned sheet matrix into dispersed particles. For example, the particle size of the individual particles in the granular matrix is ​​on the millimeter level.

[0100] In some embodiments, the matrix strip 11 includes a smoke-generating component, which accounts for 2% to 30% of the total mass of the matrix strip 11. The smoke-generating component is easily atomized to produce a large amount of aerosol, thereby increasing the aerosol yield and providing users with a satisfying vaping experience.

[0101] When the mass percentage of the smoke-generating agent component is less than 2%, the matrix strip 11 cannot generate enough aerosols or may not generate any aerosols at all, affecting the user experience. When the mass percentage of the smoke-generating agent component is greater than 30%, the matrix strip 11 generates too much aerosol, which is prone to moisture absorption and affects the quality of the aerosols.

[0102] The mass percentage of the smoke-generating agent component is in the range of 2% to 30%, which ensures that the matrix strip 11 generates a sufficient amount of aerosol for users to inhale, while also preventing moisture absorption.

[0103] Aerosol hygroscopicity refers to the absorption of moisture from the air by aerosols.

[0104] For example, the percentage of the smoke-generating agent component based on the total mass of the matrix strip 11 can be any value or a range between any two values ​​of 2%, 4%, 6%, 8%, 10%, 15%, 20%, 25%, and 30%.

[0105] In one embodiment, the smoke-generating agent component 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 diacetins, triethyl citrate, methyl benzoate, glyceryl tributyrate); monocarboxylic acid; dicarboxylic acid; polycarboxylic acid (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 carbonate, triacetin, meso erythritol, a mixture of diacetins, diethyl caprylate, triethyl citrate, methyl benzoate, phenylacetic acid, ethyl vanillate, glyceryl tributyrate, and lauryl acetate).

[0106] In one embodiment, the matrix strip 11 further includes plant components, auxiliary components, adhesive components, and fragrance components.

[0107] The plant-based components are used to generate aerosols upon heating. The adjuvant components provide skeletal support for the plant-based components. The binder components bind the various component raw materials together. The flavoring components provide characteristic aromas. Thus, the plant-based and smoke-generating components ensure sufficient aerosol generation, while the flavoring components enhance aroma release during inhalation, improving the user experience. The adjuvant components not only improve the flowability of the mixture but also give the matrix strip 11 a porous structure, facilitating aerosol extraction and flow. The binder components ensure a stable mixture of plant-based powder and adjuvants, preventing a loose structure.

[0108] In one embodiment, the plant component is one or more of the following: raw tobacco leaves, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants, which are powdered after being crushed. The plant component is the core source of the aroma, and the endogenous substances in the plant component can produce physiological satisfaction for the user. Endogenous substances, such as alkaloids, enter the human bloodstream and promote the pituitary gland to produce dopamine, thereby obtaining physiological satisfaction.

[0109] In one embodiment, the adjuvant component 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 provide skeletal support for the plant components, and also possess micropores, which can increase the porosity of the matrix strip 11, thereby improving the aerosol release rate.

[0110] 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 component powders, reduce friction between the powder particles, resulting in a more uniform overall density of the powder distribution. They can also reduce the pressure required during extrusion molding and decrease die wear.

[0111] 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.

[0112] In one embodiment, the adhesive component achieves close contact with the component raw materials through wetting at the interface, generating intermolecular attraction, thereby binding the various component raw materials, such as powders and liquids. The adhesive component can be one or more combinations of natural plant extracts and non-ionic modified viscous polysaccharides, including tamarind polysaccharides, guar gum, and modified cellulose (such as carboxymethyl cellulose).

[0113] For example, an adhesive can be used to bond the granular plant components together, making the substrate strip 11 a granular aggregate that is not easily loosened. Furthermore, it improves the water resistance of the substrate strip 11 and is harmless to humans.

[0114] In one embodiment, the flavoring component is used to provide characteristic aromas, such as hay, roasted sweetness, or solid or liquid substances of nicotine. The flavoring component may include one or more combinations of tobacco, aromatic plant extracts, extracts, essential oils, and absolutes; the flavoring component may include one or more monomeric aroma substances, such as one or more combinations of megastigmatrienone, neophytadiene, geraniol, nerol, etc.

[0115] This application also provides an aerosol generating article 10, including a matrix segment 1 and at least one functional segment 2 as described in any embodiment of this application, wherein the matrix segment 1 and the functional segment 2 are disposed along a first direction.

[0116] As an example, functional segment 2 may provide at least one of the following: filtration function, adsorption function, aroma enhancement function, dilution function, cooling function, and resistance adjustment function.

[0117] Filtration function refers to the function of filtering out at least some of the particulate matter in aerosols.

[0118] 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.

[0119] The aroma-enhancing function refers to the function of adding aroma-producing components to aerosols.

[0120] The dilution function refers to the function of reducing the concentration of active ingredients in aerosols.

[0121] Cooling function refers to the function of reducing the temperature of aerosols.

[0122] 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.

[0123] In one embodiment, please refer to Figure 7 Functional segment 2 includes a support segment 21, which can withstand the temperature from the aerosol in matrix segment 1 and maintain its shape. The support segment 21 provides support.

[0124] In one embodiment, please refer to Figure 7 Functional section 2 includes a cooling section 22, which is used to reduce the temperature of the aerosol. This makes the aerosol suitable for users to inhale, avoiding the problem of "scalding the mouth".

[0125] In one embodiment, please refer to Figure 7 Functional section 2 includes a filter section 23, which is used to filter aerosols. For example, filter section 23 can block substances of a target particle size and can also adjust the suction resistance. For instance, filter section 23 can filter large-diameter particles, similar to powdery substances. Aerosols filtered through filter section 23 have a higher particle size uniformity and a smoother taste.

[0126] In one embodiment, please refer to Figure 7 and Figure 8 Functional segment 2 includes a front plug segment 24, which can directly contact the matrix segment 1. The main function of the front plug segment 24 is to clean and prevent the matrix segment 1 from falling off.

[0127] In one embodiment, please refer to Figure 7 The fore plug section 24, the matrix section 1, the support section 21, the cooling section 22, and the filter section 23 are connected sequentially along the first direction.

[0128] In another embodiment, please refer to Figure 8 The aerosol generating article 10 may also consist only of a matrix section 1 and a filter section 23, which are arranged along a first direction. In this embodiment, the matrix section 1 can be ignited to generate an aerosol.

[0129] It should be noted that the direction in which the aerosol generating product 10 of functional segment 2 and matrix segment 1 is inserted into the apparatus and the direction in which the aerosol generating product 10 is removed from the apparatus are both parallel to the first direction.

[0130] In one embodiment, the aerosol-generating article 10 includes a coating layer that covers the outer periphery of a matrix segment 1 and the outer periphery of a functional segment 2. For example, the coating layer is wound to form a wrapping space, within which both the functional segment 2 and the matrix segment 1 are located. Exemplarily, a plurality of matrix strips 11 may be filled into the wrapping space.

[0131] For example, functional segment 2 includes a front plug segment 24, a support segment 21, a cooling segment 22, and a filter segment 23, with a coating layer covering the outer peripheral surfaces of the matrix segment 1 and the functional segment 2. That is, the outer peripheries of the front plug segment 24, matrix segment 1, support segment 21, cooling segment 22, and filter segment 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-generated product 10. For example, during manufacturing, the support segment 21, cooling segment 22, and filter segment 23 can be first wrapped with a single coating layer, and then another coating layer can be used to wrap the matrix segment 1 and the front plug segment 24. Of course, other combinations are also possible.

[0132] In some embodiments, the matrix segment 1 includes an outer sheath, which is wound to form an accommodating space with openings at both ends along a first direction, and a plurality of matrix strips 11 are accommodated within the accommodating space; the wrapping layer wraps at least a portion of the functional segment 2 and at least a portion of the outer sheath.

[0133] For example, the wrapping layer can wrap a portion of functional segment 2 and a portion of the outer wrapping layer. The wrapping layer can wrap a portion of functional segment 2 and the entirety of the outer wrapping layer. The wrapping layer can also wrap the entirety of functional segment 2 and a portion of the outer wrapping layer. The wrapping layer can also wrap the entirety of functional segment 2 and the entirety of the outer wrapping layer.

[0134] Multiple matrix strips 11 are housed within the accommodating space, meaning that the outer sheath wraps around multiple matrix strips 11 to constrain the matrix strips 11.

[0135] In some embodiments, multiple substrate strips 11 may not be bonded together with adhesive material, but rather the multiple substrate strips 11 may be bound together by an outer sheath, and the substrate strips 11 may be constrained by friction to prevent the substrate strips 11 from coming out of the receiving space.

[0136] In this embodiment, the outer layer is used to constrain the matrix strip 11, and the wrapping layer connects the matrix segment 1 and the functional segment 2 into a whole.

[0137] The material of the wrapping layer is not limited, but includes, but is not limited to, cigarette paper or other materials.

[0138] The material of the outer layer is not limited, but includes, but is not limited to, cork paper or other materials.

[0139] Regarding the heat-resistant, non-combustible matrix segment 1, this application also provides an aerosol generation system, including an aerosol generation device and an aerosol generation article 10 as described in any embodiment of this application. The aerosol generation device includes a heating element for heating the aerosol generation article 10 to generate aerosol.

[0140] Specifically, the heating element heats the substrate section 1 to generate an aerosol, and the specific method by which the heating element heats the substrate section 1 is not limited.

[0141] For example, the heating element is a resistance heating wire, which is attached to the aerosol generating product 10. After the heating element is turned on, it transfers heat to the matrix segment 1 to generate aerosol in the matrix segment 1. As another example, the heating element is a laser heating device, which irradiates the aerosol generating product 10 with a high-energy laser to raise the temperature of the matrix segment 1, thereby generating aerosol in the matrix segment 1.
