Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic atomization technology, and more particularly to an aerosol-generating product. Background Technology
[0002] Heat-not-burning (HNB) aerosol generating products use electronic devices to heat an aerosol generating matrix to produce an inhalable aerosol. When inhaled using electronic heating equipment, consumers can not only enjoy the aroma of the aerosol generating matrix but also avoid the harmful substances produced by high-temperature pyrolysis during combustion. These aerosol generating products are becoming increasingly popular both domestically and internationally.
[0003] Existing aerosol generation products mainly consist of a matrix section, a cooling section, and a filter section. The cooling section allows aerosols to pass through and reduces their temperature. Most current aerosol generation products that achieve aerosol cooling utilize hot airflow condensation components. During suction, air passes through the heated raw material medium, carrying away the generated hot aerosols, which are then condensed as they pass through the condensation components, thus achieving a cooling effect.
[0004] However, existing condensing firmware uses high-temperature aerosol to transfer heat to the firmware to reduce the aerosol temperature. The firmware itself needs heat conduction to dissipate heat. Therefore, when the firmware's heat dissipation rate is less than the heat output rate of the hot aerosol, this type of firmware often cannot achieve a significant cooling effect and will cause the aerosol to condense in the cooling area, resulting in a decrease in aerosol utilization and affecting the user's suction experience. Summary of the Invention
[0005] This application provides an aerosol generation article, aiming to develop an aerosol generation article that can effectively reduce aerosol temperature, reduce aerosol condensation rate, improve aerosol uniformity and suction smoothness during aerosol extraction, and enhance the user experience.
[0006] To solve the above-mentioned technical problems, one technical solution adopted in this application is: This application provides an aerosol generating article.

[0008] Optionally, the specific heat capacity of the anti-condensation material layer is 0.3 kJ / (kg*℃) to 2.0 kJ / (kg*℃).
[0009] Optionally, the specific heat capacity of the anti-condensation material layer is 0.31 kJ / (kg*℃) to 1.95 kJ / (kg*℃).
[0010] Optionally, the anti-condensation material layer is arranged to form a hollow column, and the anti-condensation material layer covers the entire inner surface of the sidewall of the wrapping layer.
[0011] Optionally, the matrix segment is configured to form a hollow column, and the anti-condensation material layer further covers at least a portion of the inner surface of the sidewalls of the matrix segment.
[0012] Optionally, the thickness ratio of the coating layer to the anti-coagulation material layer is 1:0.5 to 1:29.
[0013] Optionally, the thickness ratio of the coating layer to the anti-coagulation material layer is 1:0.6 to 1:27.
[0014] Optionally, the aerosol generating product is a two-stage product; the cooling stage consists of the coating layer and the anti-condensation material layer.

[0016] The filtration section; the cooling section is located between the matrix section and the filtration section.
[0017] Optionally, it also includes a housing, in which the matrix section and the cooling section are housed.
[0018] Optionally, the material of the wrapping layer includes one or more of fiber paper, polyethylene (PE), polylactic acid (PLA), and polyethylene terephthalate (PET); and / or
[0019] The anti-coagulation material layer is made of one or more of the following: graphite, graphene, carbon nanotube film, metal foil, and polymer composite materials.
[0020] The aerosol generating article provided in this application includes a matrix section and a cooling section; the cooling section is connected to the matrix section to cool the aerosol generated by atomizing the aerosol generating matrix in the matrix section; wherein, the cooling section includes a coating layer and an anti-condensation material layer, and the coating layer is arranged to form a hollow column shape; the anti-condensation material layer is disposed on the inner surface of the sidewall of the coating layer, and the thermal conductivity of the anti-condensation material layer is 200W / (m*k)~4500W / (m*k). Because the anti-condensation material layer has high thermal conductivity, it can conduct heat away from the aerosol as it flows through the cooling section, thus reducing the aerosol's temperature and achieving a cooling effect. Furthermore, as the aerosol's energy is absorbed and balanced by the anti-condensation material layer as it flows through the cooling section, subsequent aerosols reaching this section will also be temperature-balanced by the cooling section's structure. This reduces the aerosol condensation rate, improves temperature consistency, and enhances the user experience. Attached Figure Description

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0032] The present application will now be described in detail with reference to the accompanying drawings and embodiments.
[0033] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the aerosol-generating article provided in the first embodiment of this application. Figure 2 This is a cross-sectional schematic diagram of the aerosol generating article provided in the first embodiment of this application. The aerosol generating article 10 includes a shell 1, a matrix section 2, and a cooling section 3. The matrix section 2 and the cooling section 3 are housed within the shell 1 to obtain the aerosol generating article 10; specifically, the shell 1 can be paper-based or other high-temperature resistant materials.
[0034] Matrix segment 2 is used to store the aerosol generation matrix. The aerosol generation matrix is a solid matrix of plant leaves with a specific aroma, which can generate aerosols under heating conditions; the form of the aerosol generation matrix is not limited to ordered solid aerosol generation matrix, disordered solid aerosol generation matrix, and particulate solid aerosol generation matrix.
[0035] The cooling section 3 is located on one side of the matrix section 2 and is used to cool the aerosol formed by atomization in the matrix section 2 to prevent the aerosol temperature from becoming too high. The central axis of the cooling section 3 coincides with the central axis of the matrix section 2.
[0036] Specifically, in this embodiment, the length of the substrate segment 2 and the length of the cooling segment 3 can be equal, for example, 29mm, 25mm, and 15mm respectively.
[0037] Please refer to further information. Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the cooling section provided in the first embodiment of this application. Figure 4 This is a cross-sectional schematic diagram of the cooling section provided in the first embodiment of this application. The cooling section 3 includes a wrapping layer 31 and an anti-condensation material layer 32.
[0038] The encapsulation layer 31 forms a hollow columnar shape. The thickness of the encapsulation layer 31 can be 0.02mm to 0.3mm, for example, 0.04mm, 0.08mm, 0.12mm, 0.16mm, 0.20mm, 0.24mm, 0.26mm, or 0.30mm. The main materials of the encapsulation layer 31 include one or more of the following polymeric materials: fiber paper, polyethylene (PE), polylactic acid (PLA), and polyethylene terephthalate (PET).
[0039] An anti-condensation material layer 32 is disposed on the inner surface of the sidewall of the wrapping layer 31, defining channels for aerosol flow to cool the aerosol flowing through the cooling section 3. In one specific embodiment, the anti-condensation material layer 32 covers the entire inner surface of the sidewall of the wrapping layer 31, forming a closed-loop anti-condensation material layer 32 to simultaneously cool the aerosol flowing through the cooling section 3 from all directions, improving the temperature uniformity of the aerosol. Specifically, the anti-condensation material layer 32 can be in the form of a hollow cylinder or a hollow sheet.
[0040] In one specific embodiment, the cooling section 3 is formed by composite rolling of an anti-condensation material layer 32 and a wrapping layer 31. The term "composite" means that the anti-condensation material layer 32 and the wrapping layer 31 are combined into a denser two-layer structure by adhesive bonding or hot pressing. Therefore, the cooling section 3 has better support strength and can better maintain its own shape, thereby supporting part of the aerosol generation matrix, eliminating the need for a support section design and reducing costs.
[0041] The specific heat capacity of the anti-condensation material layer 32 ranges from 0.3 kJ / (kg*℃) to 2.0 kJ / (kg*℃), and the thermal conductivity ranges from 200 W / (m*K) to 4500 W / (m*K). This means the anti-condensation material layer 32 possesses both low specific heat capacity and high thermal conductivity, reducing the temperature of the aerosol and thus improving the uniformity of suction. During user operation, as the aerosol flows through the cooling section 3, its energy is absorbed by the anti-condensation material layer 32 and balanced. Subsequent aerosols reaching the cooling section 3 are also temperature-balanced by its structure, further reducing aerosol condensation, improving aerosol temperature consistency, and enhancing the user experience.
[0042] Specifically, the material of the anti-condensation material layer 32 may include one or more of the following materials with hydrophobic properties, high thermal conductivity, and low specific heat capacity: graphite, graphene, carbon nanotube film, metal foil, and polymer composite materials.
[0043] The thickness ratio of the coating layer 31 to the anti-condensation material layer 32 ranges from 1:0.5 to 1:29. When the ratio is less than 1:0.5, the temperature of the aerosol flowing through the anti-condensation material layer 32 will be higher, affecting the user's suction experience. Conversely, when the ratio is greater than 1:29, the temperature of the aerosol flowing through the anti-condensation cooling section 3 will drop excessively, increasing the condensation rate in the anti-condensation material layer 32 area and reducing aerosol utilization. Therefore, a thickness ratio of 1:0.5 to 1:29 is reasonable.
[0044] Specifically, the thickness ratio of the coating layer 31 to the anti-condensation material layer 32 is 1:0.6 to 1:27. For example, the thickness ratio of the coating layer 31 to the anti-condensation material layer 32 can also be 1:0.7, 1:0.8, 1:0.9, 1:1, 1:1.2, 1:3, 1:6, 1:9, 1:10, 1:12, 1:15, 1:18, 1:21, 1:24, 1:27 or 1:29.
[0045] The thermal conductivity of the anti-condensation material layer 32 ranges from 200 W / (m*k) to 4500 W / (m*k). When the thermal conductivity of the anti-condensation material layer 32 is below 200 W / (m*k), the energy absorbed by the aerosol flowing through this area is low, leading to a higher aerosol temperature and affecting the user's suction experience. Conversely, when the thermal conductivity of the anti-condensation material layer 32 is above 4500 W / (m*k), the temperature drop of the aerosol flowing through it is excessive, increasing the condensation rate of the aerosol in the anti-condensation material layer 32 area and thus reducing the utilization rate of the aerosol. Therefore, a thermal conductivity range of 200 W / (m*k) to 4500 W / (m*k) for the anti-condensation material layer 32 is reasonable. For example, the values could be 240W / (m*k), 480W / (m*k), 1200W / (m*k), 2000W / (m*k), 2400W / (m*k), 3000W / (m*k), 3400W / (m*k), 3600W / (m*k), 4000W / (m*k), or 4500W / (m*k).
[0046] Specifically, the thermal conductivity of the anti-condensation material layer 32 ranges from 220 W / (m*k) to 4000 W / (m*k).
[0047] By making the thermal conductivity of the anti-condensation material layer 32 range from 200W / (m*k) to 4500W / (m*k), the anti-condensation material layer 32 can have good thermal conductivity, so that the heat of the aerosol can be effectively dispersed through the thermal conductivity of the anti-condensation material layer 32, thereby achieving the cooling effect of the aerosol.
[0048] Specifically, the specific heat capacity of the anti-condensation material layer 32 ranges from 0.3 kJ / (kg*℃) to 2.0 kJ / (kg*℃), and the anti-condensation material layer 32 can also be distributed in the hollow portion of the aerosol generating product 10. This is because when the specific heat capacity of the anti-condensation material layer 32 is below 0.3 kJ / (kg*℃), the energy absorbed by the aerosol flowing through this area is low, leading to a higher aerosol temperature and thus affecting the user's suction experience. Conversely, when the specific heat capacity of the anti-condensation material layer 32 is above 2.0 kJ / (kg*℃), the temperature drop of the aerosol flowing through it is too large, increasing the condensation rate of the aerosol in the anti-condensation material layer 32 area, which in turn reduces the utilization rate of the aerosol. Therefore, a specific heat capacity of 0.3 kJ / (kg*℃) to 2.0 kJ / (kg*℃) for the anti-condensation material layer 32 is reasonable.
[0049] Specifically, the thermal conductivity of the anti-condensation material layer 32 ranges from 0.31 kJ / (kg*℃) to 1.95 kJ / (kg*℃). For example, the thermal conductivity of the anti-condensation material layer 32 can be 0.4 kJ / (kg*℃), 0.6 kJ / (kg*℃), 0.8 kJ / (kg*℃), 1.0 kJ / (kg*℃), 1.2 kJ / (kg*℃), 1.4 kJ / (kg*℃), 1.6 kJ / (kg*℃), or 2.0 kJ / (kg*℃).
[0050] In a specific embodiment, the aerosol generating product 10 is a two-section structure consisting only of a matrix section 2 and a cooling section 3; and compared with the prior art's three-section structure including a support section, the aerosol generating product 10 has a simple structure and has advantages such as simple manufacturing, simple process flow and low production cost.
[0051] By further increasing the specific heat capacity of the anti-condensation material layer 32 to a range of 0.3 kJ / (kg*℃) to 2.0 kJ / (kg*℃), the heat on the anti-condensation material layer 32 can be effectively dispersed through its good thermal conductivity. Compared to storing heat on the anti-condensation material layer 32, this prevents the heat on the anti-condensation material layer 32 from being conducted back to the aerosol, thus avoiding the problem of the aerosol temperature rising or the heat on the anti-condensation material layer 32 having a certain heat preservation effect on the aerosol.
[0052] Please refer to further information. Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of the aerosol-generating article provided in the second embodiment of this application. Figure 6 This is a cross-sectional schematic diagram of the aerosol generating article provided in the second embodiment of this application. The aerosol generating article 10 provided in this embodiment further includes a filter section 4; a cooling section 3 is located between the matrix section 2 and the filter section 4; the filter section 4 is used to filter impurities in the aerosol, and the material of the filter section 4 includes, but is not limited to, cellulose acetate, polylactic acid, polypropylene, and paper filter media; simultaneously, it increases suction resistance to ensure consistent suction. In this embodiment, the central axis of the matrix section 2 coincides with the central axis of the cooling section 3 and the central axis of the filter section 4, respectively. The matrix section 2, cooling section 3, and filter section 4 are housed within the shell 1 to obtain the aerosol generating article 10. The shape, structure, and specific function of the anti-condensation material layer 32 and the encapsulation layer 31 of the aerosol generating article 10 provided in this embodiment are similar to or the same as those in the first embodiment described above, and will not be repeated here.
[0053] In this specific embodiment, the aerosol generating product 10 can be a three-section structure including a matrix section 2, a cooling section 3, and a filtration section 4; compared with the four-section structure of the prior art that also includes a support section, the aerosol generating product 10 has the advantages of simple manufacturing, simple process flow, and low production cost.
[0054] See Figure 7 , Figure 7 This is a cross-sectional schematic diagram of an aerosol-generating article provided in another embodiment. The aforementioned anti-condensation material layer 32 can be further extended into the matrix section 2. When the aerosol heating temperature is below 260°C, this improves the maintenance effect of the aerosol matrix on the aerosol temperature at the critical atomization temperature, further balancing the aerosol temperature and enhancing the user experience. In a specific embodiment, the anti-condensation material layer 32 can also be distributed in other hollow portions of the aerosol-generating article 10 to balance the aerosol temperature.

The coating layer 31 is a PE polymer film coating layer 31 with a thickness of 0.2 mm. The cooling section 3 is obtained by wrapping the anti-condensation material layer 32 with the PE polymer film coating layer 31 and then performing a composite process. In this experimental group, the thickness ratio of the coating layer 31 to the anti-condensation material layer 32 is 1:4.
[0060] By connecting the cooling section 3, which is 25 mm long, to the matrix section 2, which is 15 mm long, and the filter section 4, which is 10 mm long, along the central axis, the aerosol generating product 10 can be obtained.
[0061] Experimental Group 3: The cooling section 3 of the aerosol-generated product 10 consists of an anti-condensation material layer 32 and a wrapping layer 31. The anti-condensation material layer 32 is formed into a sheet with a thermal conductivity of 3800 W / (m*k) and a width of 19.8 mm through an arc discharge process, and then rolled into a tube with a diameter of 6.3 mm. The wrapping layer 31 is a PE fiber paper wrapping layer 31 with a thickness of 0.3 mm. The cooling section 3 is obtained by wrapping the anti-condensation material layer 32 with the PE fiber paper wrapping layer 31 and then laminating them together. In this experimental group, the thickness ratio of the wrapping layer 31 to the anti-condensation material layer 32 is 1:0.7.
[0062] By connecting the cooling section 3 (29 mm in length) and the matrix section 2 (29 mm in length) along the central axis, the aerosol-generated product 10 can be obtained.
[0063] The aerosol products 10 obtained from the control group, experimental group 1, experimental group 2 and experimental group 3 were evaluated. According to the YC / T138-1998 Sensory Evaluation Standard for Tobacco and Tobacco Products, an evaluation group composed of 15 evaluation experts was organized to evaluate the aerosol products of the control group and all aerosol products 10 provided by the three experimental groups and test their inhalation resistance index. The evaluation and test results are listed in Table 1 below.
[0064] Table 1: Evaluation Results of Aerosol-Generated Products
[0065]
[0066] Specifically, as shown in Table 1, compared with the control sample K, the smoke volume score of experimental group 1 increased by 2 points, the smoke flow score increased by 1 point, the uniformity score increased by 2 points, and the total score increased by 3.5 points, with improvements in all aspects of performance.
[0067] Specifically, as shown in Table 1, compared with the control sample K, the smoke volume score of experimental group 2 increased by 1 point, the smoke flow score increased by 1 point, the uniformity score increased by 1.5 points, and the total score increased by 5 points, with improvements in all aspects of performance.

[0069] As can be clearly seen from Table 1, the aerosol-generated products 10 provided by the three experimental groups have relatively significant improvements in terms of smoke volume, flue gas smoothness, uniformity, flue gas temperature, and suction resistance, and their overall sensory quality has also been significantly improved.
[0070] This application discloses an aerosol generating article 10, which includes a matrix section 2 and a cooling section 3. The matrix section 2 contains an aerosol generating matrix; the cooling section 3 is disposed on one side of the matrix section 2 and includes an anti-condensation material layer 32 and a coating layer 31; the coating layer 31 is formed into a hollow column shape, and the anti-condensation material layer 32 is disposed on the inner surface of the sidewall of the coating layer 31, and the thermal conductivity of the anti-condensation material layer 32 is 200W / (m*k)~4500W / (m*k). Because the anti-condensation material layer 32 has high thermal conductivity, it can conduct heat away from the aerosol as it flows through the cooling section 3, thus reducing the aerosol's temperature and achieving a cooling effect. Furthermore, as the aerosol's energy is absorbed and balanced by the anti-condensation material layer 3 as it flows through the cooling section 3, subsequent aerosol temperatures reaching the cooling section 3 are balanced by its structure, reducing aerosol condensation and improving temperature consistency, thereby enhancing the user experience. The anti-condensation material layer 32 can also extend to the matrix section 2, improving the aerosol matrix's temperature maintenance at the critical atomization temperature when the aerosol heating temperature is below 260°C, further balancing the aerosol temperature and improving the user experience. Moreover, compared to the existing four-segment structure of aerosol products, the aerosol generating product 10 provided in this application is a two-segment structure including a cooling segment 3 and a matrix segment 2, or a three-segment structure including a cooling segment 3, a matrix segment 2 and a filtration segment 4. This makes the aerosol generating product 10 simple to manufacture, has a simple process flow, and low production cost.
