Description

Technical Field

[0001] This invention relates to the field of aerosol generation technology, and specifically to an aerosol generation product. Background Technology

[0002] Aerosol generating products are used to generate aerosols for users to inhale. They typically have a medium section and a functional section, and are formed by wrapping with shaping paper. The medium section contains an aerosol generating medium, which can generate aerosols under specific conditions such as heating. The aerosols are then cooled and / or filtered by the functional section before being inhaled by the user.

[0003] In related technologies, some aerosol-generating products incorporate atomizing agents in the medium section to increase the aerosol mist volume and improve the aerosol's taste. However, since atomizing agents are typically hydrophilic materials, the forming paper is prone to moisture absorption, affecting the product's appearance and quality. Furthermore, the forming paper has poor impermeability; when users use aerosol-generating products, the atomizing agent and the aerosol-generating medium can easily seep through the forming paper, causing aerosol loss and further impacting the product's appearance. These issues result in a poor user experience with aerosol-generating products. Summary of the Invention

[0004] In view of this, the present invention provides an aerosol generating article to solve the problem of poor user experience of existing aerosol generating articles.

[0005] To solve the above problems, the technical solution of the present invention is implemented as follows:

[0006] An aerosol generating article includes: a medium portion having an aerosol generating medium and an atomizing agent, wherein the content of the atomizing agent is 10%-30% of the total weight of the medium portion; a functional component disposed at one end of the medium portion; and a coating layer including at least one first coating layer composed of a regenerated cellulose membrane, wherein the first coating layer at least covers the medium portion.

[0007] In some embodiments, the basis weight of the first coating layer is 15-60 g / m³. 2 .

[0008] In some embodiments, the thickness of the first wrapping layer is 10-40 μm.

[0009] In some embodiments, the air permeability of the first wrapping layer is no greater than 20 COS units.

[0010] In some embodiments, the first wrapping layer also covers the functional components.

[0011] In some embodiments, the wrapping layer further includes at least one second wrapping layer that covers at least the functional component.

[0012] In some embodiments, the second wrapping layer further covers the medium portion, and at least one second wrapping layer is stacked on the side of the first wrapping layer opposite to the medium portion; and / or, the first wrapping layer further covers the functional component, and at least one second wrapping layer is stacked on the side of the first wrapping layer opposite to the functional component.

[0013] In some embodiments, an adhesive layer is provided between the first wrapping layer and the second wrapping layer to fix the first wrapping layer and the second wrapping layer.

[0014] In some embodiments, the wrapping layer includes one first wrapping layer and two second wrapping layers, with the two second wrapping layers respectively stacked on both sides of the first wrapping layer.

[0015] In some embodiments, the wrapping layer includes multiple first wrapping layers, each of the first wrapping layers being stacked sequentially, and at least one second wrapping layer being stacked outside the outermost first wrapping layer.

[0016] In some embodiments, the total basis weight of the encapsulation layer is 25-80 g / m³. 2 .

[0017] In some embodiments, the total thickness of the wrapping layer is 40-90 μm.

[0018] In some embodiments, the total air permeability of the wrapping layer is no greater than 20 COS units.

[0019] The aerosol generating product provided in this embodiment of the invention includes a medium, functional components, and a coating layer. The medium has an aerosol generating medium and an atomizing agent, with the atomizing agent content being 10%-30% of the total weight of the medium. The coating layer includes at least one first coating layer composed of a regenerated cellulose membrane, and the first coating layer at least covers the medium. In this way, the coating layer utilizes the good anti-leakage properties of the regenerated cellulose membrane, effectively reducing the problem of aerosol leakage through the coating layer, thereby reducing aerosol loss, improving aerosol utilization, and extending the service life of the aerosol generating product. Furthermore, by utilizing the anti-leakage properties of the regenerated cellulose membrane, the coating layer is less prone to moisture absorption, thus improving the overall appearance of the aerosol generating product and better preventing the moisture-affected coating layer from contaminating the surrounding environment or the user's skin. Simultaneously, the coating layer produces less paper odor when heated, reducing the impact of paper odor on aerosol quality. By adopting the above design, the aerosol generating product provided in this embodiment of the invention offers a better user experience. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0034] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0035] Aerosol generating products are used to generate aerosols for users to inhale. They typically consist of a medium section and a functional section, which are wrapped in forming paper to form a specific shape, such as a cylinder. The medium section stores an aerosol generating medium, which can generate aerosols under specific conditions such as heating or ignition. After being processed by the functional section, the aerosols are ready for users to inhale.

[0036] Aerosol generating media typically exist in two forms: solid and liquid. Traditional aerosol generating products usually store a solid form of aerosol generating medium and generate aerosols by igniting the medium. The forming paper used in such aerosol generating products (hereinafter referred to as ignition-type products) is usually a single layer of paper, and this layer of paper is usually manufactured in accordance with the industry standard "Filter Rod Forming Paper (YC / T208-2006)".

[0037] With the development of related technologies, a type of aerosol generating product (hereinafter referred to as a heated product) has emerged on the market that generates aerosols by heating a medium. Its main difference from traditional ignition-type products is that it does not require an open flame to ignite the medium. When using this type of heated product, a matching heating device is typically used to heat the medium in the medium section, causing the medium to release aerosols. After processing in the functional section, the aerosols are ready for the user to inhale. For heated products, the forming paper serves a similar function to that used in traditional ignition-type products, acting as a wrapping and shaping agent. Furthermore, the forming paper used in heated products is typically manufactured using the same process as that used in ignition-type products.

[0038] In related technologies, some heated products incorporate atomizing agents in the medium section to increase the aerosol mist volume and improve the aerosol's taste. However, atomizing agents are typically hydrophilic materials such as glycerin and propylene glycol, which easily absorb moisture from the outside air through the forming paper. This leads to moisture absorption in the forming paper, affecting the product's appearance and quality. Moistened forming paper can also contaminate the surrounding environment or the user's skin, impacting the user experience. Furthermore, conventional forming paper has poor impermeability. When users use aerosol-generated products, the atomizing agent and the aerosol-generating medium can easily seep through the forming paper, causing aerosol loss and resulting in low aerosol utilization in the product. This also further affects the product's appearance.

[0039] To solve the above problems, such as Figure 1 As shown, this embodiment of the invention provides an aerosol generating article 1, which is a heated article and includes a medium section 11, a functional component 12, and a coating layer 13. The medium section 11 has an aerosol generating medium and an atomizing agent, the content of which is 10%-30% of the total weight of the medium section 11. The functional component 12 is disposed at one end of the medium section 11 to process the aerosol. The coating layer 13 includes at least one first coating layer 131 made of regenerated cellulose membrane, which at least covers the medium section 11.

[0040] Specifically, the aerosol generating medium in the medium section 11 is typically a solid medium that releases aerosols upon heating to a certain degree without the need for open flame ignition. The aerosols generated by the medium section 11 are processed by the functional component 12 and then output to the outside environment for user absorption. The atomizing agent in the medium section 11 can be materials such as glycerin or propylene glycol, which generate a mist when heated and mix with the aerosols generated by the aerosol generating medium, thereby increasing the aerosol mist volume and adjusting the aerosol odor. By controlling the atomizing agent content to 10%-30% of the total weight of the medium section 11, a better aerosol quality can be achieved, and the moisture absorption problem caused by the atomizing agent can be reduced to some extent.

[0041] Specifically, the processing of aerosols by functional component 12 typically involves lowering the temperature of the aerosol to control the temperature of the aerosol during output within a suitable range. Of course, depending on the design, functional component 12 can also perform other processing on the aerosol to further improve its quality. For example, in some embodiments, functional component 12 includes a cooling element 121 and a filter element 122. The cooling element 121 is connected to the medium section 11, the filter element 122 is connected to the cooling element 121, and the first coating layer 131 covers at least both the cooling element 121 and the filter element 122 simultaneously. In this way, the aerosol can be cooled by the cooling element 121 to a temperature suitable for human absorption, and larger particles mixed in the aerosol can be filtered by the filter element 122, thereby improving the aerosol's taste. Optionally, flavoring capsules can be added to the filter element 122, and flavorings or other substances can be added to the cooling element 121 to adjust the flavor of the aerosol and provide a richer taste experience. In other embodiments, the functional component 12 may also include a support member 123, which may be disposed between the medium section 11 and the cooling member 121, or integrally formed with the cooling member 121, to provide support at the middle position of the aerosol-generated article 1 and improve structural strength.

[0042] Specifically, the first coating layer 131 is composed of a regenerated cellulose membrane, which is a thin film structure with high cellulose crystallinity made from natural fiber materials through a specific process. Optionally, the fiber material used to make the regenerated cellulose membrane can be one or more combinations of fiber materials such as hemp pulp fiber, softwood pulp fiber, hardwood fiber, cotton pulp fiber, and straw pulp fiber, and the fiber material has a high cellulose crystallinity after processing, for example, not less than 85%. The manufacturing process of the regenerated cellulose membrane typically includes: alkalizing the raw material to obtain alkali cellulose, esterifying it to obtain cellulose xanthate, dissolving it to obtain cellulose viscose, extruding it through a film stretching machine, and drying it to form a film, which is the regenerated cellulose membrane. By using the above-mentioned fiber materials and manufacturing process, the first coating layer 131 composed of a regenerated cellulose membrane can be obtained. This first coating layer 131 has strong anti-permeability properties and is not prone to moisture absorption and leakage problems.

[0043] Optionally, the wrapping layer 13 may consist of only one first wrapping layer 131, thereby simplifying the manufacturing process and reducing costs while meeting the impermeability requirements. Of course, the wrapping layer 13 may also include multiple first wrapping layers 131 to further enhance its impermeability. The first wrapping layer 131 may only cover the medium portion 11, or it may further cover other structures. In some embodiments, the wrapping layer 13 may also include other material layers that cover structures other than the medium portion 11, or simultaneously cover the medium portion 11 with the first wrapping layer 131, to improve the aesthetics of the wrapping layer 13 or enhance other related properties, as will be further explained in the following embodiments. It is understood that the design of the wrapping layer 13 is highly flexible; it only needs to ensure that the first wrapping layer 131 at least covers the medium portion 11, thereby reducing moisture absorption and enhancing impermeability at least at the medium portion 11.

[0044] The aerosol generating product 1 provided in this embodiment of the invention includes a medium section 11, a functional component 12, and a coating layer 13. The medium section 11 contains an aerosol generating medium and an atomizing agent. The content of the atomizing agent is 10%-30% of the total weight of the medium section, which has a good effect on improving the quality of aerosols and can reduce the moisture absorption problem caused by the atomizing agent to a certain extent. The coating layer 13 includes at least one first coating layer 131 made of regenerated cellulose membrane, and the first coating layer 131 covers at least the medium section 11. In this way, the coating layer 13 utilizes the good impermeability of the regenerated cellulose membrane, making it difficult for the atomizing agent and the aerosol generating medium in the medium section 11 to leak through the first coating layer 131, effectively reducing the problem of aerosol leakage, improving the utilization rate of the atomizing agent and aerosols, and also improving the quality of aerosol output, thereby extending the service life of the aerosol generating product 1. Furthermore, by utilizing the impermeable properties of the regenerated cellulose membrane, the coating layer 13 is less prone to moisture absorption, thus improving the overall appearance of the aerosol-generating product 1 and effectively preventing the moisture-affected coating layer 13 from contaminating the surrounding environment or the user's skin, thereby impacting the user experience. Simultaneously, the coating layer 13 with the regenerated cellulose membrane produces less paper odor when heated, reducing the impact of paper odor on aerosol quality. Additionally, since the regenerated cellulose membrane is a biodegradable material, it also reduces environmental pollution caused by the coating layer 13, aligning with green environmental protection principles. Through the above design, the aerosol-generating product 1 provides a better user experience.

[0045] In some embodiments, the basis weight of the first encapsulation layer 131 is designed to be 15-60 g / m³. 2 Alternatively, in some embodiments, the basis weight of the first wrapping layer 131 can be designed to be 25-35 g / m³. 2 Thus, the first coating layer 131 possesses good structural strength, meeting the strength requirements of the aerosol-generated product 1 during the molding process. Specifically, the assembly and molding of the aerosol-generated product 1 is typically achieved using a specialized molding machine, which stretches and rolls the coating layer 13 to complete the coating operation. The basis weight of the first coating layer 131 is designed to be no less than 15 g / m³. 2 Therefore, the wrapping layer 13 is less prone to tearing or obvious creases during stretching and curling, ensuring reliable wrapping and good product appearance integrity. Furthermore, the basis weight of the first wrapping layer 131 is no greater than 60 g / m³. 2 This can effectively reduce the paper odor generated by the first wrapping layer 131 when heated, thereby reducing the impact of paper odor on aerosol quality and improving the cleanliness of the aerosol.

[0046] In some embodiments, the thickness of a single layer of the first wrapping layer 131 is 10-40 μm. Optionally, the thickness of a single layer of the first wrapping layer 131 can be set to 15-25 μm. This design provides a moderate thickness for the first wrapping layer 131, achieving both good leak-proof performance and structural strength. Furthermore, the thickness of the first wrapping layer 131 is not excessive, resulting in less paper odor generated when heated, and also helps control the manufacturing cost of the wrapping layer 13, improving material utilization. It is understood that when the wrapping layer 13 comprises multiple layers of the first wrapping layer 131, the thickness of each first wrapping layer 131 can be set within the aforementioned range, and the thicknesses of each layer can be stacked.

[0047] Optionally, the thickness of the first coating layer 131 can be uniform or non-uniform. When the thickness of the first coating layer 131 is uniform, it is easier to process and manufacture, and the consistency of the thickness of the first coating layer 131 is easier to control. Of course, it is also possible to thicken a portion of the first coating layer 131. For example, in some embodiments, the first coating layer 131 can further cover the connection between the medium segment 11 and the functional component 12, and the connection can be thickened, thereby enhancing the effect of preventing moisture absorption and leakage at the connection. When adopting the above-mentioned local thickening design, the thickness change between the thickened part and other parts of the first coating layer 131 can be gradual or abrupt, as long as the other related structures of the aerosol generating product 1 are designed accordingly so that the coating layer 13 has a relatively uniform shape when the coating is completed.

[0048] In some embodiments, the air permeability of the first wrapping layer 131 is no greater than 20 COSTER units. A COSTER unit is a unit of air permeability for sheet materials, corresponding to 1 cm of material permeability under a measurement pressure of 1 kPa. 2 Airflow rate per square meter of surface area (in cm²) 3 / min), where the measured pressure is the pressure difference between two surfaces of the material. That is, the unit corresponding to the Costa unit is cubic centimeters per minute per square centimeter (cm²) at a measured pressure of 1 kPa. 3 ·min -1 ·cm -2 Optionally, the air permeability of the first wrapping layer 131 can be set to no more than 15 COS units, or no more than 8 COS units, thereby further reducing the air permeability level of the first wrapping layer 131. By controlling the air permeability of the first wrapping layer 131 within the above range, the moisture-proof and leak-proof performance of the first wrapping layer 131 can be better guaranteed, improving the user experience of the aerosol-generated product 1.

[0049] In some embodiments, such as Figure 1As shown, the first coating layer 131 also covers the functional component 12, meaning that the first coating layer 131 can simultaneously cover the medium portion 11 and the functional component 12. With this design, the first coating layer 131 covers a larger area, providing a seepage-proof function for both the medium portion 11 and the functional component 12, further enhancing the seepage-proof performance of the aerosol-generated product 1, and also improving the overall strength of the coating layer 13.

[0050] Optionally, in some embodiments, the position of the first wrapping layer 131 corresponding to the local structure of the functional component 12 can be thickened. The local structure can be a cooling element 121 or other structure in the functional component 12. By increasing the thickness of the first wrapping layer 131 located at this structure, the anti-leakage effect can be enhanced for the cooling element 121 and other positions that are prone to aerosol condensation, and the leakage of substances generated by condensation can be better prevented.

[0051] In some embodiments, such as Figure 1 and Figure 2 As shown, the encapsulation layer 13 further includes at least one second encapsulation layer 132, and the second encapsulation layer 132 at least covers the functional component 12. In this way, with at least a first encapsulation layer 131 provided at the medium portion 11 and at least a second encapsulation layer 132 provided at the functional component 12, it is possible to encapsulate the aerosol generating article 1 as a whole.

[0052] Optionally, the second wrapping layer 132 can be paper made according to the industry standard "Filter Rod Forming Paper (YC / T208-2006)", or it can be made of materials that can be rolled and deformed, such as aluminum foil, tin foil, plastic film, PLA (polylactic acid fiber). Optionally, the second wrapping layer 132 can be provided as a single layer or multiple layers. The material and thickness parameters of different second wrapping layers 132, or different parts of the same second wrapping layer 132, can be the same or different.

[0053] Optionally, the areas covered by the first wrapping layer 131 and the second wrapping layer 132 may not overlap; that is, the first wrapping layer 131 may only cover the medium portion 11, and the second wrapping layer 132 may only cover the functional component 12. Of course, the areas covered by the first wrapping layer 131 and the second wrapping layer 132 may also partially overlap. For example, in one embodiment, such as... Figure 2 As shown, the first wrapping layer 131 and the second wrapping layer 132 partially overlap at the connection between the medium portion 11 and the functional component 12. Alternatively, the areas covered by the first wrapping layer 131 and the second wrapping layer 132 can completely overlap, allowing for a more flexible design; it is sufficient that the wrapping layer 13 can simultaneously cover both the medium portion 11 and the functional component 12.

[0054] In some embodiments, such as Figure 3As shown, the second wrapping layer 132 also covers the medium portion 11, and at least one second wrapping layer 132 is stacked on the side of the first wrapping layer 131 facing away from the medium portion 11. Specifically, the first wrapping layer 131 may only cover the medium portion 11, while the second wrapping layer 132 covers both the medium portion 11 and the functional component 12, and is located on the side of the first wrapping layer 131 facing away from the medium portion 11.

[0055] When the above design is adopted, the second wrapping layer 132 can at least cover part of the first wrapping layer 131 covering the medium portion 11 to improve the aesthetics of the product, and can further improve the anti-seepage performance of the wrapping layer 13 at the medium portion 11.

[0056] Similarly, in other embodiments, such as Figure 1 As shown, the first wrapping layer 131 also covers the functional component 12, and at least one second wrapping layer 132 is stacked on the side of the first wrapping layer 131 facing away from the functional component 12. That is, the first wrapping layer 131 can cover both the medium part 11 and the functional component 12 at the same time, so the second wrapping layer 132 can only cover the functional component 12, thereby covering the relevant structure of the functional component 12 and part of the first wrapping layer 131, thereby improving the aesthetics of this part, and further improving the waterproof performance of the wrapping layer 13 at the functional component 12.

[0057] Of course, the first wrapping layer 131 and the second wrapping layer 132 can also simultaneously cover the medium portion 11 and the functional component 12, such as... Figure 4 As shown, this design results in better overall aesthetics, consistent waterproofing throughout, and allows the first wrapping layer 131 and the second wrapping layer 132 to be of equal length, thus ensuring uniform length dimensions during processing and facilitating manufacturing.

[0058] In some embodiments, such as Figure 5 As shown, when the areas covered by the first coating layer 131 and the second coating layer 132 overlap, an adhesive layer 133 can be provided between the first coating layer 131 and the second coating layer 132 to bond and fix the first coating layer 131 and the second coating layer 132. Specifically, the adhesive layer 133 is formed of an adhesive material, and the first coating layer 131 and the second coating layer 132 are bonded and fixed through the adhesive layer 133, thereby forming a multi-layer composite structure coating layer 13. Optionally, the material of the adhesive layer 133 can be one or a combination of several of vinyl acetate-ethylene copolymer emulsion, vinyl acetate emulsion, and modified starch.

[0059] Of course, the first coating layer 131 and the second coating layer 132 can also be encapsulated separately and sequentially to encapsulate the structure of the aerosol-generated product 1. For example, the first coating layer 131 can be encapsulated first, and then the second coating layer 132 can be encapsulated on the outside of the first coating layer 131, which can also achieve the function of encapsulation and shaping.

[0060] Optionally, the first wrapping layer 131 and the second wrapping layer 132 in the wrapping layer 13 can each be provided with one or more layers. For example, in one embodiment, such as Figure 6 As shown, the wrapping layer 13 may include a first wrapping layer 131 and two second wrapping layers 132. The two second wrapping layers 132 are respectively stacked on both sides of the first wrapping layer 131, and the two second wrapping layers 132 and the first wrapping layer 131 can be bonded and fixed together by adhesive layers 133. In another embodiment, as shown... Figure 7 As shown, the wrapping layer 13 may include multiple first wrapping layers 131, each first wrapping layer 131 being stacked sequentially, and at least one second wrapping layer 132 being stacked on the outside of the outermost first wrapping layer 131, and any two adjacent layers can be bonded and fixed together by an adhesive layer 133.

[0061] Optionally, when the first wrapping layer 131 and the second wrapping layer 132 are provided with multiple layers, the first wrapping layer 131 and the second wrapping layer 132 can be stacked alternately or multiple layers of the first wrapping layer 131 or the second wrapping layer 132 can be stacked continuously, which provides a relatively flexible arrangement. As an example, considering factors such as cost and manufacturing process, the total number of layers of the first wrapping layer 131 and the second wrapping layer 132 can be designed to be two or three layers.

[0062] In some embodiments, the total weight of the encapsulation layer 13 is 25-80 g / m³. 2 Optionally, the total weight of the wrapping layer 13 can be set to 55-75 g / m³. 2 With this design, the total weight of the wrapping layer 13 can better meet the structural strength requirements, allowing the wrapping layer 13 to achieve a better wrapping effect through the forming machine. When using the forming machine for mass production, controlling the weight range of the wrapping layer 13 can also better ensure the consistency of product quality.

[0063] In some embodiments, the total thickness of the wrapping layer 13 is 40-90 μm. Optionally, the total thickness of the wrapping layer 13 can be set to 50-70 μm. The total thickness of the wrapping layer 13 refers to the sum of the thicknesses of each layer; that is, when the wrapping layer 13 is a multi-layered structure, the sum of the thicknesses of each layer is within the above range. With this design, the wrapping layer 13 has moderate structural strength and hardness, and also has good impermeability.

[0064] In some embodiments, the total air permeability of the wrapping layer 13 is no greater than 20 COS units. Optionally, the air permeability of the wrapping layer 13 can be set to no greater than 8 COS units, or even no greater than 10 COS units, thereby further reducing the air permeability level of the wrapping layer 13. By controlling the total air permeability of the wrapping layer 13 within the above range, the moisture-proof and leak-proof performance of the wrapping layer 13 can be better guaranteed, improving the user experience of the aerosol-generated product 1.

[0065] To facilitate the explanation of the beneficial effects of the embodiments of the present invention, an aerosol generating article 1 (hereinafter referred to as Product A) provided in the embodiments of the present invention is compared with a related aerosol generating article (hereinafter referred to as Product B). Product A is formed by wrapping with a regenerated cellulose membrane layer 13, while Product B is formed by wrapping with conventional forming paper without a regenerated cellulose membrane.

[0066] The total particulate matter and nicotine content in the aerosol components of products A and B were measured, and the results are shown in Table 1. As can be seen from the data in Table 1, the aerosol particulate matter content and nicotine content of product A are both increased to some extent compared to product B.

[0067] Table 1. Content of aerosol components in product A and product B

[0068]

[0069] Products A and B were placed in an environment with a temperature of 35℃ and a humidity of 70% for 24 hours. The penetration of atomizing agent and moisture in the medium section of both products was observed, and the results are as follows: Figure 8 As shown in the figure, product A has a relatively clean overall appearance and does not show obvious signs of moisture or seepage, while product B shows more obvious signs of moisture and seepage.

[0070] Product A and Product B were placed in the same suction device for a suction test. The leakage of the cigarettes after suction was observed, and the results are as follows: Figure 9 As shown in the figure, it is clear that product A has a cleaner appearance and no obvious leakage, while product B has more obvious leakage.

[0071] As can be seen from the above comparison, Product A has a higher content of effective components in its aerosol compared to Product B, meaning less loss. Furthermore, under the same environmental conditions, Product A is less prone to moisture absorption and seepage. Therefore, Product A (i.e., the aerosol-generating product 1 provided in this embodiment of the invention) has better moisture-proof and seepage-proof properties.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
