Description

Technical Field

[0001] This application relates to the field of tobacco technology, and in particular to a composition for preparing aerosol-generating articles and an aerosol-generating article. Background Technology

[0002] Aerosol-generating products can form aerosols through ignition or atomization, or through a heat-non-combustible method. Heat-non-combustible aerosol-generating products utilize an external heat source to heat the aerosol-generating matrix just enough to release aerosols without burning.

[0003] Heated tobacco products using aerosol generation can reduce harmful substances produced by combustion by about 90%, while also significantly reducing the release of sidestream smoke and ambient smoke. These new types of tobacco products are gradually becoming a trend in the industry. However, heated tobacco products also have quality defects such as a weaker smoke flavor and aroma, resulting in a poorer smoking experience.

[0004] Therefore, there is a need for an improved aerosol-generating article that can solve or mitigate at least one of the problems existing in the prior art. Summary of the Invention

[0046] It should be noted that the terms "first," "second," and "third" used in the embodiments of this application are merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted.

[0047] Generally, heated non-combustible aerosol generators reduce a large number of harmful substances produced by combustion, but they also reduce the characteristic aroma of aerosol generators and lower the user's inhalation experience.

[0048] In view of this, the first aspect of this application provides a composition for preparing a component of an aerosol-generating article. The composition of this application can improve the retention rate of fragrance components in the component of the aerosol-generating article, thereby improving the sustained release of aroma from the aerosol-generating article and enhancing its quality.

[0049] The composition of this application includes: a skeleton component; a smoke-generating agent component; a curing agent component; a fragrance component; an adhesive component; and a sustained-release excipient component, wherein the sustained-release excipient has a molecular structure with ring-shaped cavities.

[0050] In this application, the term "cyclic cavity" refers to the internal space formed by cyclic molecules, in which multiple repeating units (e.g., glucose units, benzene rings, etc.) are linked end-to-end by chemical bonds to form a closed ring structure.

[0051] In this application, the component used for aerosol generation is a "porous structure," which refers to a structure with high porosity. This ensures efficient aerosol generation, and the interconnected pores form a three-dimensional network structure, which helps reduce suction resistance. In this application, the "porous structure" is a microporous structure. Micropores are formed by the gaps between the components of the composition after molding. These micropores are irregular and belong to the category of pores in a microscopic sense. The size of the micropores is determined by the gaps between the powder particles after molding.

[0052] In this application, the skeleton component provides a supporting framework for the parts of the aerosol-generated article, which is beneficial for composition molding. It also provides attachment sites for other components, such as flavoring components, thereby improving the aroma quality of the aerosol-generated article. The smoke-generating component easily atomizes to produce aerosols, providing users with a satisfying inhalation experience. The curing agent component, on the one hand, works with the skeleton component to provide a supporting framework, improving the robustness and stability of the parts; on the other hand, it acts as a lubricant, reducing friction between the composition slurry and the equipment during molding, and improving the surface finish of the molded parts. The flavoring component provides characteristic aromas to the aerosol-generated article, such as tobacco aroma, thereby enhancing the user's inhalation experience. The adhesive component, through wetting and close contact with the material interfaces of each component in the composition, generates intermolecular attraction, thus binding the powders, liquids, etc., of the component materials. The sustained-release excipient component has a ring-shaped cavity structure, which can encapsulate the flavoring component, forming a microencapsulated structure, thereby facilitating the slow and uniform release of the flavoring component, improving aroma consistency during inhalation, and enhancing the user's sensory experience.

[0053] In some embodiments, the sustained-release excipient component is selected from one or more of α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin, maltodextrin, modified starch, xanthan gum, curdlan gum, and sodium octenyl succinate. These sustained-release excipient components can encapsulate and microencapsulate flavor components, thereby achieving slow and uniform release of the flavor components. For example, α-cyclodextrin, β-cyclodextrin, and γ-cyclodextrin have cyclic cavity structures and can encapsulate small, medium, and large molecules, serving as carriers for flavor components; maltodextrin, modified starch, xanthan gum, and curdlan gum can act as thickening and stabilizing agents during the microencapsulation process, facilitating the encapsulation of flavor components during extrusion; sodium octenyl succinate is starch modified by esterification, introducing hydrophobic groups (octenyl), exhibiting amphiphilicity (hydrophilic / hydrophobic), which is beneficial for the microencapsulation of flavor components. By adding the above-mentioned slow-release excipients, it is possible to encapsulate and microencapsulate different types of fragrance components, avoiding the problem of excessively rapid release of fragrance components during high-temperature and high-pressure extrusion, and improving the retention rate of fragrance components during molding; in addition, it is also beneficial for the slow and uniform release of fragrance components during the suction process.

[0054] In this application, "fragrance retention rate" is quantitatively calculated as the ratio of fragrance component content in the parts before and after molding of the aerosol-generated article. The fragrance retention rate (%) = (fragrance component content after molding / fragrance component content before molding) × 100%. The content of the fragrance component can be measured using methods known to those skilled in the art, such as gas chromatography-mass spectrometry. In this application, the terms "fragrance component retention rate" and "fragrance retention rate" are used interchangeably.

[0055] In some embodiments, the smoke-generating agent component includes one or more of propylene glycol, glycerol, sorbitol, and glucomannan. The aforementioned aerosol matrix is ​​readily atomized to form an aerosol, which can increase or supplement the aerosol, thus improving the smoke volume of the aerosol-generated product. In some preferred embodiments, the aerosol matrix includes one or both of propylene glycol and glycerol.

[0056] In some embodiments, the curing agent includes one or more of calcium carbonate, talc, kaolin, and diatomaceous earth. All of these curing agents are inorganic fillers with safe components. For example, calcium carbonate and talc are food additives and are used in pharmaceuticals; kaolin and diatomaceous earth are used in the paper industry. Adding a curing agent to the composition can act as a skeletal crosslinking agent and filler for the slurry, improving the strength and hardness of the extruded parts; furthermore, it can act as a lubricant, reducing friction between the slurry particles and the molding equipment, increasing the success rate of extrusion; and it can also improve the surface smoothness of the prepared parts, avoiding unevenness on the outer surface.

[0057] In some embodiments, the backbone component includes one or more of cellulose, microcrystalline cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, amylose, amylopectin, and modified starch. These backbone components, being polysaccharides, possess the characteristics of a robust interfacial film, which can enhance the intermolecular adhesion within the components of the prepared aerosol-generated product and improve product processing stability. This helps maintain the smoothness of the outer surface of the prepared component, enhancing its aesthetics and facilitating the transport of aerosol substances. Furthermore, these backbone components have a high specific surface area, providing more binding sites for the fragrance component, facilitating adsorption and binding with the fragrance component to form a microscopic encapsulation effect. This improves the fragrance retention rate during the preparation of the aerosol-generated product and allows for the uniform and slow release of the fragrance component during aspiration, improving aspiration consistency and thus enhancing the user experience.

[0058] In some embodiments, the flavoring component includes one or more of solid and liquid flavorings. Solid flavorings refer to substances that remain solid at room temperature (e.g., in block, granule, or flake form) and possess a specific aroma. Solid flavorings have a pure aroma and a slow-release characteristic during inhalation of aerosol-generated products, which helps improve the aroma consistency of the aerosol-generated product. Liquid flavorings refer to substances that remain liquid or have fluidity at room temperature and possess a specific aroma. Liquid flavorings can provide a rich variety of aromas and offer a better inhalation experience. Furthermore, liquid flavorings can be easily and uniformly dispersed in the composition, improving the uniformity of the aerosol-generated product. In addition, liquid flavorings also improve the processability of the composition and enhance the quality of the prepared components. In some embodiments, the solid flavoring includes one or more of clove powder, kudzu root powder, gel flavoring, and microcapsule flavoring. In some embodiments, the liquid flavoring includes one or more of menthol, blueberry flavoring, eugenol, and tobacco extract.

[0059] In some embodiments, the adhesive includes one or more of sodium carboxymethyl cellulose, sodium alginate, guar gum, tamarind gum, and pullulan. These adhesive components are safe and widely available.

[0060] In some embodiments, the content of the smoke-generating agent component is 5%-25% based on the total mass of the composition. Exemplarily, the content of the smoke-generating agent component, based on the total mass of the composition, can be 5%, 8%, 10%, 15%, 18%, 20%, 22%, 25%, or a value within a range of any two of these values.

[0061] In some embodiments, the curing agent content is 15%-45% based on the total mass of the composition. For example, the content of the smoke-generating agent component can be 15%, 20%, 25%, 30%, 35%, 40%, 45%, or a range of any two of these values ​​based on the total mass of the composition.

[0062] In some embodiments, the content of the skeleton component is 15%-50% based on the total mass of the composition. For example, the content of the skeleton component based on the total mass of the composition can be 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, or a range consisting of any two of these values.

[0063] In some embodiments, the content of the flavoring component is 4%-10% based on the total mass of the composition. Exemplarily, the content of the flavoring component is 4%, 5%, 6%, 7%, 8%, 9%, 10%, or a range consisting of any two of these values, based on the total mass of the composition.

[0064] In some embodiments, the adhesive content is 5%-15% based on the total mass of the composition. For example, the adhesive content can be 5%, 8%, 10%, 12%, 15%, or a range consisting of any two of these values, based on the total mass of the composition.

[0065] In some embodiments, the content of the sustained-release excipient component is 1%-10% based on the total mass of the composition. Exemplarily, the content of the sustained-release excipient component, based on the total mass of the composition, can be 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, or a value between any two of these values.

[0066] By ensuring the content of each component in the composition is within the aforementioned range, it is beneficial to adjust the viscosity of the composition, improve its processing performance, and thereby enhance the quality of the components of the prepared aerosol-generating article. Furthermore, the content of the smoke-generating component within the aforementioned range also helps to increase the amount of smoke produced by the aerosol-generating article. The content of the fragrance component within the aforementioned range also helps to improve the aroma quality of the aerosol-generating article. The content of the skeleton component and the sustained-release excipient component within the aforementioned range also helps to improve the fragrance retention rate during the preparation of the aerosol-generating article component, and further helps to improve the mechanical properties of the prepared component.

[0067] In some embodiments, the composition further includes water. Adding water to the composition facilitates thorough and uniform mixing of the various components, helps adjust the viscosity of the composition, improves its processability, avoids problems such as material buildup or clogging during preparation, or incomplete composition formation, and improves the quality of the prepared parts.

[0068] In some embodiments, the ratio of the total mass of the components other than water to the mass of water in the composition is 1:0.1 to 0.3. By keeping the water content in the composition within this range, it is beneficial for the slurry formed by mixing the composition and water to have suitable viscosity and flowability, thereby facilitating molding and improving the quality of the components of the prepared aerosol-generated article. Exemplarily, the ratio of the total mass of the components other than water to the mass of water in the composition can be 1:0.1, 1:0.15, 1:0.2, 1:0.25, 1:0.3, or a value within a range of any two of these values.

[0069] In some embodiments, the curing agent has a powder particle size of 60-200 mesh. In some embodiments, the adhesive has a powder particle size of 60-200 mesh. In some embodiments, the skeleton component has a powder particle size of 60-200 mesh. This is beneficial for improving the processing performance of the composition, avoiding problems such as pore blockage during the preparation process, and improving the quality of the prepared parts.

[0070] In some embodiments, the solid fragrance has a particle size of 100-200 mesh. This facilitates uniform dispersion of the solid fragrance components in the composition, improves aroma consistency, enhances the processing performance of the composition, and improves the quality of the prepared components.

[0071] In some embodiments, the aerosol generating article is selected from combustible aerosol generating articles, heated non-combustible aerosol generating articles, and / or atomized aerosol generating articles.

[0072] In some embodiments, the component includes micropores. Micropores refer to the gaps between the components that form microscopic pores after the composition used to prepare the component is molded. This facilitates the formation of aerosols.

[0073] In some embodiments, the cross-sectional area of ​​the micropore is 0.7 nm. 2 ~710μm 2 Alternatively, the hydraulic diameter of the micropores is 10 nm to 30 μm.

[0074] In some embodiments, the cross-sectional area of ​​the micropore is 1963 nm. 2 ~20μm 2 Alternatively, the hydraulic diameter of the micropores is 50 nm to 5 μm.

[0075] In some embodiments, the component further includes an air passage that extends through at least one end of the component along its length. This improves the component's air permeability.

[0076] In some embodiments, the air passage extends through opposite ends of the component along its length.

[0077] In some embodiments, the component has multiple air passages inside.

[0078] In some embodiments, the cross-sectional shape of the air passage is circular, elliptical, racetrack-shaped, fan-shaped, or polygonal in a plane perpendicular to the length direction of the component.

[0079] In some embodiments, the cross-sectional area of ​​the airway orifice is 0.0019 mm. 2 -30mm 2Alternatively, the hydraulic diameter of the airway orifice is 0.05mm-6mm.

[0080] In some embodiments, the wall thickness of the spacer wall between adjacent airway openings is 10 μm to 800 μm.

[0081] Taking a heat-not-combustible aerosol-generating product as an example, the following is combined with the appendix. Figure 1-4 The structure of the aerosol-generating article of this application is illustrated by way of example.

[0082] In some implementations, reference Figures 1 to 2 The aerosol generating article includes a matrix segment 20, a functional segment 30, and an encapsulation layer (not shown). The encapsulation layer covers the circumferential exterior of the functional segment and the aerosol generating matrix.

[0083] The matrix segment 20 has two axial ends, namely a proximal lip end 20a and a distal lip end 20b. The proximal lip end 20a refers to the end of the matrix segment 20 that is closer to the user's lips when the user uses the aerosol-generated product, and the distal lip end 20b refers to the end of the matrix segment 20 that is farther away from the user's lips when the user uses the aerosol-generated product.

[0084] This application does not limit the specific structure of the functional section 30, which includes at least one of the following: the front plug section 10, the filter section 31, the support section 32, and the cooling section 33.

[0085] The coating layer can protect the aerosol-generating matrix. The coating layer includes, but is not limited to, one or more of the following materials: fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, polyethylene (PE), polybutylene terephthalate (PBAT).

[0086] In some implementations, please refer to Figure 1 and Figure 2 The functional section 30 includes one or more of the following: a filter section 31, a support section 32, and a cooling section 33. The functional section is located near the lip end 20a of the matrix section 20.

[0087] In some implementations, such as Figure 1 As shown, the functional segment 30 includes a filter segment 31, which is disposed near the lip end 20a of the matrix segment 20 along its axial direction. The aerosol generated by the aerosol generating matrix is ​​transported to the filter segment under suction negative pressure. The filter segment is used to filter and / or adsorb some particulate matter and harmful substances in the aerosol, improving the user's suction experience and enhancing the safety of the aerosol-generated products. Furthermore, the process of the aerosol being loosened by the filter segment before reaching the user can reduce the temperature of the aerosol, mitigating the "burning" sensation when the user inhales the aerosol.

[0088] In some implementations, such as Figure 2The functional section includes a filter section 31, a support section 32, and a cooling section 33. The support section 32 is located at one end of the matrix section 20 along its axial direction, one end of the cooling section 33 is located at the end of the support section 32 away from the matrix section 20 along its axial direction, and the filter section 31 is located at the other end of the cooling section 33.

[0089] The support section 32 can connect and support the matrix section 20 and the cooling section 33 at both ends. The cooling section 33 is used to reduce the temperature of the aerosol so that the temperature of the aerosol flowing out of the filter section 31 is suitable and avoids the problem of the aerosol being "hot to the mouth".

[0090] Of course, the positions of the support section and the cooling section can also be interchanged, that is, the cooling section 33 is connected to one end of the matrix section 20 along the axis, and the two ends of the support section 32 are connected to the other end of the cooling section 33 and the filter section 31, respectively.

[0091] In some implementations, reference Figure 3 and Figure 4 The functional section 30 includes one or more of the following: a pre-plug section 10, a filter section 31, a support section 32, and a cooling section 33. One or more of the filter section 31, support section 32, and cooling section 33 are disposed at one end of the aerosol generating matrix 20 along its length, and the pre-plug section is disposed at the other end of the aerosol generating matrix 20 along its length. The encapsulation layer wraps around the circumferential exterior of the functional section and the matrix section. The pre-plug section improves the problem of aerosol generating matrix 20 detachment. Furthermore, the pre-plug section 10 can adsorb the condensed and refluxed aerosol after the aerosol generating product stops pumping, thereby avoiding the problem of aerosol condensation flowing downwards and causing internal contamination of the aerosol generating device, making it difficult to clean, and preventing cross-contamination of flavors when pumping different flavored aerosol generating products.

[0092] In some implementations, such as Figure 3 As shown, the aerosol generating article includes a pre-plug section 10, a matrix section 20, a cooling section 33, a filter section 31, and a coating layer (not shown). The pre-plug section is located at the distal lip end 20b of the aerosol generating matrix, the cooling section is located at the proximal lip end 20a of the aerosol generating matrix, and the filter section is located at the other end of the cooling section away from the aerosol generating matrix.

[0093] In some implementations, such as Figure 4 As shown, the aerosol generating article includes a pre-plug section 10, a matrix section 20, a support section 32, a cooling section 33, a filter section 31, and a coating layer. The pre-plug section is located at the distal lip end 20b of the aerosol generating matrix, the support section 32 is located at the proximal lip end 20a of the aerosol generating matrix, and the cooling section 33 is located at the end of the support section 32 axially away from the aerosol generating matrix 20. The filter section 31 is located at the end of the cooling section 33 axially away from the support section 32.

[0094] This application does not limit the structure of the functional segments and / or matrix segments. In some exemplary embodiments, such as Figure 5 As shown, the functional segment and / or matrix segment itself has numerous micropores, which are interconnected to form micro-channels. It can be understood that after the functional segment and / or matrix segment is formed, the gaps between its raw material components constitute micropores. These micropores are irregular and belong to the category of pores in a microscopic sense. The size of the micropores is determined by the gaps between the powder components after the powder is formed.

[0095] During the aerosol generation process, the generated aerosols can enter the microchannels of the functional section. Under the negative pressure generated by suction, the aerosols are transported to the user for inhalation through the microchannels. In addition, as the aerosols flow through the microchannels, it also helps the functional section capture some substances in the aerosols and has a cooling effect.

[0096] In some embodiments, the cross-sectional area of ​​the micropore is 0.7 nm. 2 ~710μm 2 Alternatively, the hydraulic diameter of the micropores is 10 nm to 30 μm.

[0097] In some embodiments, the cross-sectional area of ​​the micropore is 1963 nm. 2 ~20μm 2 Alternatively, the hydraulic diameter of the micropores is 50 nm to 5 μm.

[0098] In some embodiments, the pre-plug section and the filter section themselves have numerous micropores, which are interconnected to form micro-air channels.

[0099] In other exemplary embodiments, such as Figure 6 and Figure 7 As shown, the functional segment and / or matrix segment includes micropores and at least one airway opening, which extends through at least one end of the functional segment and / or matrix segment along its length. The airway opening helps improve the air permeability of the functional segment and reduce suction resistance.

[0100] It should be noted that the airway pores mentioned above are pores in a macroscopic sense, while micropores are pores in a microscopic sense. The cross-sectional area of ​​an airway pore is much larger than that of a micropore, for example, at least 20 times larger.

[0101] In some embodiments, the cross-sectional area of ​​the airway pores is 20 to 60,000 times that of the micropores. This is beneficial for balancing the structural stability of the functional segment and / or matrix segment with the aerosol release rate. In some embodiments, the cross-sectional area of ​​the airway pores is 100 to 40,000 times that of the micropores.

[0102] The micro-airways are connected to the airway pores. Since the micro-airways are formed by the interconnection of micropores, the micropores are also connected to the airway pores. Furthermore, it can be understood that the interconnection between micropores can be partial, with some micropores not connected, or all micropores can be interconnected. A portion of the aerosol in the micro-airways can also be collected at the airway pores and delivered to the user's mouth under the negative pressure of suction. The airway pores help reduce the suction resistance for the user, improving the user experience. It should be noted that suction resistance is positively correlated with the flow resistance of the aerosol; the lower the flow resistance of the aerosol, the lower the perceived suction resistance, and vice versa.

[0103] In some embodiments, the airway opening extends through both ends of the functional segment and / or matrix segment along its length. This helps to reduce suction resistance for the user.

[0104] In one implementation, such as Figure 6 As shown, the functional segment and / or matrix segment has an airway opening inside. This helps to reduce the suction resistance for the user.

[0105] In some implementations, such as Figure 7 As shown, the functional segment and / or matrix segment have multiple airway pores inside. This is more conducive to reducing the suction resistance for the user.

[0106] In some embodiments, the cross-sectional shape of the airway opening is circular, elliptical, racetrack-shaped, fan-shaped, or polygonal in a plane perpendicular to the length direction of the functional segment and / or matrix segment.

[0107] In some embodiments, the cross-sectional area of ​​the airway orifice is 0.0019 mm. 2 -30mm 2 Alternatively, the hydraulic diameter of the air passage orifice is 0.05mm-6mm. In this application, the hydraulic diameter refers to the ratio of four times the cross-sectional area to the perimeter. In some preferred embodiments, the cross-sectional area of ​​the air passage orifice is 0.007mm². 2 ~7.1mm 2 (square millimeters). In some preferred embodiments, the hydraulic diameter of the airway orifice is 0.1 mm to 3 mm. This facilitates more uniform aerosol release and higher utilization.

[0108] In some embodiments, the wall thickness of the spacer wall between adjacent air passages is 10 μm to 800 μm. This facilitates heat penetration and diffusion, resulting in higher heat transfer efficiency, while also maintaining structural strength.

[0109] In some embodiments, the components of the aerosol-generating article are selected from one or more of the following: a matrix section, a pre-plug section, a cooling section, a support section, and a filter section. Using the composition of this application to prepare the above-mentioned components is beneficial for improving the retention rate of fragrance components, thereby enhancing the sustained release of fragrance components during the inhalation process of the aerosol-generating article, improving aroma consistency, and thus improving the user's inhalation experience.

[0110] In some embodiments, the components of the aerosol generating article are manufactured using a one-piece molding process. This one-piece molding process overcomes the problems of filament shedding, residue loss, and difficulty in cleaning that occur during the aerosol generating article's extraction process. This, in turn, improves the user experience.

[0111] In some embodiments, the integral molding process is selected from one or more of extrusion molding, injection molding, die casting, and 3D printing. Extrusion molding refers to a processing method in which a raw material composition is added to an extruder, and the material is heated and plasticized by the action between the extruder barrel and screw, while being pushed forward by the screw, continuously passing through the die head to form products or semi-finished products of various cross-sections. The extruded parts are strip-shaped. Because the parts are of an integral structure, they remain a unified medium after the aerosol-generated product is heated and absorbed or after heating stops, preventing disintegration and falling off, thus reducing problems such as filament shedding, slag shedding, and difficulty in cleaning.

[0112] In some embodiments, the integral molding process is carried out under constant temperature conditions, specifically 30°C to 120°C. Performing the integral molding process at these temperatures facilitates good viscosity and flowability of the components in the composition, improves the consistency and stability of the molding process, reduces energy consumption, and reduces thermal stress, thus extending the service life of the molding equipment. Exemplarily, the constant temperature can be 30°C, 50°C, 80°C, 100°C, 120°C, or any two of these values. Exemplarily, performing the integral molding process under constant temperature conditions specifically includes heating the composition to a set temperature and then molding the composition, for example, by extruding the heated composition using a screw extruder. Exemplarily, the extrusion molding process parameters also include a screw speed of 50-200 r / min. Exemplarily, the screw speed can be 50 r / min, 100 r / min, 150 r / min, 200 r / min, or any two of these values.

[0113] In some embodiments, the integral molding process is performed under segmented temperature variations, which include: a first stage temperature of 30℃-80℃; a second stage temperature of 90℃-110℃; a third stage temperature of 120℃-160℃; and a fourth stage temperature of 170℃-200℃. The integral molding process under segmented temperature variations is suitable for situations where the material needs to avoid thermal decomposition, such as when fragrance components are added. Since fragrance components are easily decomposed at high temperatures, segmented heating can gradually increase the temperature and reduce fragrance loss. Furthermore, the integral molding process under segmented temperature variations can improve the mixing and homogenization of the composition slurry. Different temperature stages may promote the dispersion of various components, thereby changing the texture of the product and improving the quality of the prepared parts.

[0114] A second aspect of this application also provides an aerosol-generating article comprising components prepared using the composition described in the first aspect of this application. This improves the mechanical strength of the components and the retention rate of fragrance components in the aerosol-generating article, thereby enhancing the aroma quality and improving the user's inhalation experience. The number of components prepared using the composition of this application in the aerosol-generating article is not limited; those skilled in the art can choose any component prepared using the composition of this application as needed. Exemplarily, the aerosol-generating article of this application includes at least one of a matrix section, a pre-plug section, a cooling section, a support section, and a filter section prepared using the composition of this application. In some preferred embodiments, the aerosol-generating article includes a matrix section, a pre-plug section, a cooling section, a support section, and a filter section prepared using the aforementioned composition.

[0115] Aerosol generating products are used in conjunction with aerosol generating devices, which include heating components and power supply components. The power supply components provide electrical energy to the heating components, which convert the electrical energy into other forms of energy and apply them to the aerosol generating matrix in the matrix section, thereby heating the aerosol generating matrix to generate aerosols for users to inhale.

[0116] This application also provides an aerosol generation system. The aerosol generation system includes an aerosol generation apparatus with a heating component and the aerosol generation article described above. Specifically, the heating component heats and atomizes the aerosol generation matrix to generate aerosols.

[0117] The present application will be described in further detail below with reference to specific embodiments. The purpose of this description is merely illustrative and not intended to limit the scope of this disclosure.
