[0005] In an embodiment, the second liquid storage section includes a first liquid guide part and a second liquid guide part. One end of the first liquid guide part is connected with the smoking section along the axial direction of the first liquid guide part, and the other end is connected with the first liquid storage section. The second liquid guide part is connected with the radially outer side of the first liquid guide part.

[0006] In an embodiment, the aerosol substrate structure further includes a protective sleeve, which surrounds the outer periphery of the smoking section, the first liquid storage section and the second liquid storage section.

[0007] In an embodiment, an annular groove is arranged on the protective sleeve located at the outer periphery of the second liquid guide part, and the annular groove is used to assemble a sealing member for sealingly connecting the protective sleeve with the liquid supplementing member.

[0008] In an embodiment, the aerosol substrate structure further comprises a liquid supplementing member and a sealing member, the liquid supplementing member comprises a storage portion and a matching portion connected with each other, the storage portion is used for storing the aerosol substrate, and the matching portion is arranged around the outer periphery of the second liquid guiding portion; and the sealing member seals the gap between the protective sleeve of the outer periphery of the second liquid guiding portion and the inner wall of the matching portion.

[0009] In an embodiment, the second liquid guiding portion comprises a first portion and a second portion, the first portion is connected with the first liquid guiding portion, and the second portion is connected with the end of the first portion away from the first liquid guiding portion; the protective sleeve is arranged around the outer periphery of the first portion; and the second portion is arranged protruding from the protective sleeve and has a gap with the inner wall of the matching portion.

[0010] In an embodiment, the first storage section and the second storage section both have a microporous structure, and the porosity of the micropores of the first storage section is the same as the porosity of the micropores of the second storage section.

[0011] In an embodiment, the aerosol substrate structure is provided with a suction channel penetrating through the suction section and the second storage section, the suction channel is used for being connected with the first storage section and a suction machine, so that the aerosol in the first storage section can flow to the suction machine through the suction channel.

[0012] In an embodiment, the aerosol substrate structure further comprises a supporting section, the supporting section is connected with the end of the first storage section away from the second storage section, and the supporting section is provided with an air inlet hole.

[0014] This application provides an aerosol matrix structure for use in the testing process of an aerosol generation device. The aerosol matrix structure includes a suction section, a first liquid storage section, and a second liquid storage section. The suction section is used to connect to a suction machine; the first liquid storage section can absorb and store the aerosol matrix; the first liquid storage section is used to insert into the heating chamber of the aerosol generation device to heat and atomize the aerosol matrix in the first liquid storage section into aerosol; one end of the second liquid storage section is connected to the suction section, and the other end of the second liquid storage section is connected to the first liquid storage section; a portion of the structure of the second liquid storage section is used to insert into a replenishment component to absorb the aerosol matrix in the replenishment component and replenish the first liquid storage section. The aerosol matrix structure provided in this application, during the aging test of the aerosol generation device, as the aerosol matrix in the first liquid storage section is heated and atomized into aerosol, the aerosol matrix content in the first liquid storage section decreases. The first liquid storage section absorbs the aerosol matrix from the second liquid storage section through capillary action and continues to generate aerosol. As a result, the aerosol matrix content in the second liquid storage section decreases. Since part of the structure of the second liquid storage section of this aerosol matrix structure is inserted into the replenishment component, the second liquid storage section can absorb the aerosol matrix in the replenishment component through capillary action, thus solving the problem of limited storage capacity in the aerosol matrix structure. This allows the aerosol matrix structure to be replenished with aerosol matrix through the replenishment component during the aging test of the aerosol generation device. Therefore, it is not necessary to replace the aerosol matrix structure due to storage capacity issues during the aging test, thus improving the efficiency of the aging test.

[0025] Please refer to Figures 1-5 The application provides an aerosol substrate structure 10, which can be applied in the test process of an aerosol generating device 20, for example, as shown in Figures 3-5As shown, during the aging test of the aerosol generating device 20, the aerosol matrix structure 10 can be inserted into the aerosol generating device 20, the aerosol matrix structure 10 can be connected to the suction machine, the suction machine can be started, and the aerosol generating device 20 can heat the aerosol matrix structure 10. The aerosol matrix structure 10 can generate aerosol, which can simulate the user's suction.

[0026] like Figures 1-4 As shown, the aerosol matrix structure 10 includes a suction section 11, a first liquid storage section 12, and a second liquid storage section 13. The suction section 11 is connected to a suction machine. When the suction machine is turned on, it generates suction to extract the aerosol generated inside the aerosol matrix structure 10 at the suction section 11. The suction section 11 is used to simulate the filter nozzle of a typical aerosol matrix structure. In a typical aerosol matrix structure, the filter nozzle is usually filled with filter material, and cooling holes can be provided on the filter nozzle to allow external cold air to enter and mix with the hot aerosol, preventing burns from the aerosol. However, the aerosol matrix structure 10 of this application is only for simulation testing; therefore, the suction section 11 only needs to ensure that it has internal air passages and does not need to be equipped with cooling holes or filter material. Of course, in other tests, cooling holes and filter material can be added to the suction section 11 as needed. The suction section 11 can be made of materials such as polyetheretherketone, ceramic, aluminum, and aluminum alloy. It is preferred to use a material with a certain degree of hardness so that the suction section 11 is not easy to collapse and can be stably connected to the suction machine.

[0027] The first liquid storage section 12 can absorb and store the aerosol matrix. The first liquid storage section 12 has a microporous structure and can absorb and store the aerosol matrix through capillary action. The first liquid storage section 12 is used to simulate the matrix section of a typical aerosol matrix structure; its function is to generate aerosols upon heating for suction. During the test, such as... Figure 4 As shown, the first liquid storage section 12 is inserted into the heating chamber of the aerosol generating device 20 so that the aerosol matrix in the first liquid storage section 12 can be heated and atomized into aerosol by the heating element of the aerosol generating device 20.

[0028] One end of the second liquid storage section 13 is connected to the suction section 11, and the other end of the second liquid storage section 13 is connected to the first liquid storage section 12. During the test, if... Figure 4As shown, the second liquid storage section 13 is located inside the aerosol generating device 20 near one end of the first liquid storage section 12, and the second liquid storage section 13 near the other end of the first liquid storage section 12 and the suction section 11 are located outside the aerosol generating device 20. The part of the second liquid storage section 13 located outside the aerosol generating device 20 is inserted into the liquid supplement 16 to absorb the aerosol substrate in the liquid supplement 16 and supplement the first liquid storage section 12. The second liquid storage section 13 has a microporous structure, so the second liquid storage section 13 can absorb and store the aerosol substrate by capillary action.

[0029] In an embodiment, the first liquid storage section 12 is configured as a first liquid storage section 12 of cotton, porous ceramic or porous metal material. The second liquid storage section 13 is configured as a second liquid storage section 13 of cotton, porous ceramic or porous metal material. The materials of the first liquid storage section 12 and the second liquid storage section 13 can be the same or different. Preferably, the materials of the first liquid storage section 12 and the second liquid storage section 13 are the same, and the porosities of the micropores of the first liquid storage section 12 and the second liquid storage section 13 are the same, to achieve good liquid transfer between the first liquid storage section 12 and the second liquid storage section 13.

[0030] The aerosol substrate structure 10 provided by the present application has aerosol substrate stored in the first liquid storage section 12 and the second liquid storage section 13 in advance. In the aging test of the aerosol generating device 20, as the aerosol substrate in the first liquid storage section 12 is heated and atomized into aerosol, the content of the aerosol substrate in the first liquid storage section 12 decreases, and the first liquid storage section 12 absorbs the aerosol substrate from the second liquid storage section 13 by capillary action and continuously generates aerosol, thereby reducing the content of the aerosol substrate in the second liquid storage section 13. Since the part of the second liquid storage section 13 of the aerosol substrate structure 10 is inserted into the liquid supplement 16, the second liquid storage section 13 can absorb the aerosol substrate in the liquid supplement 16 by capillary action, and the aerosol substrate structure 10 can always have aerosol substrate during the test to achieve dynamic balance of the aerosol content in the aerosol substrate structure 10, thereby solving the problem of limited storage capacity in the aerosol substrate structure 10 in the aging test. The aerosol substrate structure 10 can be supplemented with aerosol substrate through the liquid supplement 16, so the aerosol substrate structure 10 does not need to be replaced due to storage capacity in the aging test, thereby improving the efficiency of the aging test.

[0031] As Figures 1-4As shown, in one embodiment, the second liquid storage section 13 includes a first liquid guiding portion 131 and a second liquid guiding portion 132. One end of the first liquid guiding portion 131 along its axial direction is connected to the suction section 11, and the other end is connected to the first liquid storage section 12. Preferably, the suction section 11, the first liquid guiding portion 131, and the first liquid storage section 12 are connected sequentially, and the central axes of the suction section 11, the first liquid guiding portion 131, and the first liquid storage section 12 coincide. The suction section 11, the first liquid guiding portion 131, and the first liquid storage section 12 are generally cylindrical in shape. The second liquid guiding portion 132 is connected to the radially outer surface of the first liquid guiding portion 131. The second liquid guiding portion 132 can also be generally cylindrical in shape. Preferably, the central axis of the second liquid guiding portion 132 is perpendicular to the central axis of the first liquid guiding portion 131. By connecting the second liquid guiding part 132 to the radial outer side of the first liquid guiding part 131, it is convenient for the second liquid guiding part 132 to be connected to the liquid replenishment component 16 to absorb the aerosol matrix in the liquid replenishment component 16.

[0032] In one embodiment, such as Figure 4 As shown, the aerosol matrix structure 10 also includes a protective sleeve 14, which surrounds the outer periphery of the suction section 11, the first liquid storage section 12, and the second liquid storage section 13. Figure 4 The diagram only shows the outer periphery of the second liquid guiding section 132 wrapped with a protective sleeve 14. In reality, the outer periphery of the suction section 11, the first liquid storage section 12, and the first liquid guiding section 131 are also wrapped with protective sleeves 14. The protective sleeves 14 protect the entire aerosol matrix structure 10 and prevent the aerosol matrix from flowing out of the aerosol matrix structure 10. The protective sleeves 14 are preferably made of high-temperature resistant materials, such as materials that can withstand temperatures of 300 degrees Celsius to 1000 degrees Celsius. The materials of the protective sleeves 14 can be, for example, paper, polyetheretherketone, glass, or ceramics with low thermal conductivity, with the approximate range of low thermal conductivity being 0.01 W / (m·K) to 0.5 W / (m·K).

[0033] In one embodiment, an annular groove 141 is provided on the protective sleeve 14 located on the outer periphery of the second liquid guiding part 132. The annular groove 141 is used to assemble the sealing element 15, so as to seal the protective sleeve 14 and the liquid replenishing element 16. The sealing element 15 is, for example, a sealing ring. The sealing connection between the protective sleeve 14 and the liquid replenishing element 16 can prevent the liquid aerosol matrix from flowing out from the gap between the protective sleeve 14 and the liquid replenishing element 16.

[0034] In one embodiment, the aerosol matrix structure 10 further includes a replenishing component 16 and a sealing component 15. The replenishing component 16 includes a reservoir 161 and a mating component 162 connected to each other. The reservoir 161 is used to store the aerosol matrix. The mating component 162 is disposed around the outer periphery of the second liquid guiding component 132. A protective sleeve 14 is located between the inner wall of the mating component 162 and the second liquid guiding component 132. The sealing component 15 can seal the gap between the protective sleeve 14 around the second liquid guiding component 132 and the inner wall of the mating component 162.

[0035] Furthermore, the second liquid guiding part 132 includes a first part 1321 and a second part 1322. The first part 1321 is connected to the first liquid guiding part 131, and the second part 1322 is connected to the end of the first part 1321 away from the first liquid guiding part 131. The protective sleeve 14 surrounds the outer periphery of the first part 1321, and the protective sleeve 14 is sealed to the inner wall of the mating part 162. The second part 1322 protrudes from the protective sleeve 14, meaning that the outer periphery of the second part 1322 does not surround the protective sleeve 14. There is a gap between the second part 1322 and the inner wall of the mating part 162. Thus, the radially outer wall of the second part 1322 and the end face of the second part 1322 away from the first part 1321 can absorb the aerosol matrix in the liquid replenishment part 16, improving the liquid absorption efficiency of the second part 1322. The second part 1322 may be located only within the mating part 162, or the second part 1322 may extend from the mating part 162 into the liquid storage part 161.

[0036] In one embodiment, such as Figure 4 and Figure 5 As shown, the aerosol matrix structure 10 has a suction channel 17 that runs through the suction section 11 and the second liquid storage section 13. The suction channel 17 is used to connect with the first liquid storage section 12 and the suction machine so that the aerosol generated in the first liquid storage section 12 can flow to the suction machine through the suction channel 17. The opening of the suction channel 17 can reduce the suction resistance in the aerosol matrix structure 10.

[0037] In one embodiment, the aerosol matrix structure 10 further includes a support section 18, which is connected to the end of the first liquid storage section 12 away from the second liquid storage section 13. An air inlet is provided within the support section 18 to guide airflow into the first liquid storage section 12. The support section 18 simulates the sealing section at the bottom of a typical aerosol matrix structure, which is usually filled with cellulose acetate to prevent the aerosol matrix from falling out of the aerosol matrix structure 10. Similarly, the support section 18 of this application not only provides air intake but also prevents the aerosol matrix in the first liquid storage section 12 from flowing out. The aerosol matrix is ​​stored in the first liquid storage section 12 and the second liquid storage section 13 under capillary action.

[0038] The material of the support section 18 can be, for example, polyether ether ketone, ceramic, aluminum, aluminum alloy, etc., and preferably a material with a certain hardness so that the support section 18 can well support the entire aerosol substrate structure 10. The support section 18 can be added or cancelled according to the type of the aerosol generating device 20. For example, in the embodiment of the aerosol generating device 20 being a circumferential heating type aerosol substrate structure 10, the support section 18 can be provided, and in other embodiments, for example, the aerosol generating device 20 being a central heating type aerosol substrate structure 10, in which a heating needle needs to be inserted into the first liquid storage section 12, the aerosol substrate structure 10 in this embodiment can not include the support section 18. Figure 4

[0039] In the embodiment of the aerosol generating device 20 being a circumferential heating type aerosol substrate structure 10, the support section 18 can be provided, and in other embodiments, for example, the aerosol generating device 20 being a central heating type aerosol substrate structure 10, in which a heating needle needs to be inserted into the first liquid storage section 12, the aerosol substrate structure 10 in this embodiment can not include the support section 18. Figure 5

[0040] The above application of specific examples to the present application is only used to help understand the present application and does not limit the present application. For those skilled in the art to which the present application belongs, according to the idea of the present application, a number of simple deductions, deformations or substitutions can be made.​​
