[0029] See Figures 1 to 3 As shown, an embodiment of the present invention provides an aerosol generating product, comprising a filter segment 30, a cooling segment 20 and a matrix segment 10 of the aerosol generating product. In the length direction of the aerosol generating product 100, the filter segment 30, the cooling segment 20 and the matrix segment 10 are connected in sequence. The first opening 142 is located at one end of the aerosol generating product 100, and the first opening 142 is away from the filter segment 30. The first opening 142 is used for a heating element to pass through. The heating element is inserted into the second space 122. The heating element heats the aerosol matrix 11 located in the first space 121 to generate an aerosol. The aerosol passes through the cooling segment 20 and the filter segment 30 to be inhaled by the user of the aerosol generating product 100.
[0030] The configuration of the matrix segment 10 is as follows:
[0031] See Figures 2 to 7 As shown, the embodiment of the present invention provides a matrix segment 10, the matrix segment 10 has a central axis, and the matrix segment 10 includes: an outer coating layer 13, an inner coating layer 14 and an aerosol matrix 11. The specific embodiment is as follows:
[0032] Example 1:
[0033] See Figure 2 and Figure 3As shown, the substrate segment 10 includes an outer covering layer 13 disposed around a central axis to form a receiving cavity 12; an inner covering layer 14 disposed around the central axis and received within the receiving cavity 12. The inner covering layer 14 divides the receiving cavity 12 into a first space 121 and a second space 122. The first space 121 is adjacent to the outer covering layer 13. One end of the inner covering layer 14 has a first opening 142, which is flush with one end of the outer covering layer 13 and communicates with the second space 122. In this embodiment, the end of the inner covering layer 14 distal from the first opening 142 is located within the receiving cavity 12, and the portion above the inner covering layer 14 in the longitudinal direction constitutes a portion of the first space 121. The aerosol substrate 11 is received within the first space 121 and is heated to generate an aerosol.
[0034] See Figure 2 、 Figure 3 as well as Figure 9 As shown, the inner cover layer 14 is provided with first micropores 141 to increase the air permeability of the inner cover layer 14. This allows the aerosol generated by heating the aerosol substrate 11 to enter the second space 122. The aerosol then moves along the length of the substrate segment 10, passing through the cooling segment and reaching the filtration segment. After entering the second space 122, the aerosol moves upward without being blocked by the aerosol substrate 11, thereby reducing the draw resistance of the aerosol-generating article when inhaled by the user.
[0035] See Figure 2 and Figure 3 As shown, the inner covering layer 14 has a second opening 143, which is located at one end of the inner covering layer 14 away from the first opening 142, and the second opening 143 connects the first space 121 and the second space 122; the matrix segment 10 also includes a first packaging member 15, which covers the second opening 143 to prevent the aerosol matrix 11 from passing through the second opening 143 and entering the second space 122, thereby preventing the aerosol matrix 11 from adhering to the heating element located in the second space 122.
[0036] Specifically, the first package 15 is provided with a second micropore 151 to increase the air permeability of the first package 15, so that the aerosol located in the second space 122 passes through the second micropore 151, and moves upward in the length direction of the matrix segment 10 to pass through the cooling segment and reach the filtration segment, thereby reducing the inhalation resistance of the user when inhaling the aerosol-generating product through the second micropore 151.
[0037] In some embodiments, the first packaging member 15 is not provided, and the aerosol matrix 11 located in the first space 121 near the second opening 143 is arranged along a first direction, the first direction is the radial direction of the matrix segment 10, and the first direction is perpendicular to the length direction of the second space 122, so that the aerosol matrix 11 blocks the second opening 143, preventing the aerosol matrix 11 from passing through the second opening 143 and entering the second space 122, thereby preventing the aerosol matrix 11 from adhering to the heating element located in the second space 122.
[0038] Specifically, in the length direction of the second space 122, the aerosol matrix 11 above the second space 122 is arranged in a direction perpendicular to the length direction of the second space 122, or the aerosol matrix 11 is arranged randomly using long filaments and arranged closely to prevent the aerosol matrix 11 from passing through the second opening 143 and entering the second space 122, thereby preventing the aerosol matrix 11 from adhering to the heating element located in the second space 122.
[0039] See Figure 2 and Figure 3 As shown, the substrate segment 10 further includes a second encapsulating member 16. The outer covering layer 13 has a third opening 131, which is located at one end of the outer covering layer 13 near the first opening 142. The second encapsulating member 16 covers the third opening 131, thereby sealing the third opening 131 and the first opening 142. The second encapsulating member 16 blocks the third opening 131 to reduce moisture absorption by the aerosol substrate 11 in the first space 121, thereby improving the shelf life of the aerosol-generating product and ensuring a consistent taste and user experience of the aerosol-generating product. The second encapsulating member 16 blocks the first opening 142 to prevent foreign matter from entering the second space 122. This prevents the heating element from heating foreign matter and generating odors during use of the aerosol-generating product, ensuring a consistent taste and user experience of the aerosol-generating product. Furthermore, the second encapsulating member 16 prevents moisture from entering the second space 122, preventing the aerosol substrate 11 from absorbing moisture in the second space 122, thereby ensuring a consistent taste and user experience of the aerosol-generating product.
[0040] Example 2:
[0041] The difference between the second embodiment and the first embodiment lies in the arrangement of the inner coating layer 14 and the first packaging member 15, which are specifically arranged as follows:
[0042] See Figure 4 As shown, the inner cladding layer 14 has a second opening 143, which is located at the end of the inner cladding layer 14 away from the first opening 142; the outer cladding layer 13 has a fourth opening 132, which is located at the end of the outer cladding layer 13 away from the first opening 142, and the end of the inner cladding layer 14 with the second opening 143 is flush with the end of the outer cladding layer 13 with the fourth opening 132.
[0043] The second opening 143 is not provided with the first packaging member 15. By providing the inner covering layer 14 through the substrate segment 10, compared with the provision of the inner covering layer 14 in the first embodiment, the aerosol substrate 11 located above the second space 122 in the length direction of the substrate segment 10 is reduced. This allows the aerosol entering the second space 122 to directly reach the cooling section without being obstructed by the aerosol substrate 11, thereby reducing the inhalation resistance of the aerosol generating article when inhaled by the user. At the same time, it also reduces the heat loss of the aerosol when passing through the aerosol substrate 11, increases the temperature of the aerosol when inhaled by the user, and thus improves the mouthfeel.
[0044] In some embodiments, a first packaging component 15 is disposed at the second opening 143 , and the draw resistance of a user when inhaling the aerosol-generating article is adjusted by disposing the first packaging component 15 .
[0045] Example 3:
[0046] The difference between the third embodiment and the first embodiment lies in the arrangement of the second packaging member 16, which is specifically arranged as follows:
[0047] See Figure 5 As shown, the second packaging member 16 is covered on the first opening 142 to seal the first opening 142. The second packaging member 16 seals the first opening 142 to prevent foreign matter from entering the second space 122, thereby preventing the heating element from heating foreign matter to produce odor when the aerosol generating product is used, thereby ensuring the consistency of the taste and experience of the user using the aerosol generating product. At the same time, it can prevent moisture from entering the second space 122, and prevent the aerosol matrix 11 from absorbing moisture in the second space 122, thereby ensuring the consistency of the taste and experience of the user using the aerosol generating product.
[0048] Example 4:
[0049] The difference between the fourth embodiment and the first embodiment lies in the arrangement of the second packaging member 16, which is specifically arranged as follows:
[0050] See Figures 6 and 7 As shown, the substrate segment 10 further includes a second packaging member 16. The outer covering layer 13 has a third opening 131, which is located at one end of the outer covering layer 13 near the first opening 142. The second packaging member 16 covers the third opening 131 to block it. The second packaging member 16 defines a first through-hole 161, which communicates with the first opening 142 and serves as an entrance for the heating element to be inserted into the second space 122. The second packaging member 16 blocks the third opening 131 to reduce moisture absorption by the aerosol substrate 11 in the first space 121, thereby extending the shelf life of the aerosol-generating product and ensuring a consistent taste and user experience of the aerosol-generating product.
