[0028] Before introducing the technical solution of this application, the technical problems in the related art will be introduced in detail.

[0029] Traditional cigarettes contain large amounts of tar and nicotine, which have serious health effects on users. In response to the increasing health needs of users, cartridges 1 have been developed. The smoke-producing material 60 in cartridges 1 typically contains no tobacco ingredients or only small amounts of tobacco ingredients. Furthermore, cartridges 1 are typically heat-and-burn cartridges 1 that heat but do not burn the smoke-producing material 60. This prevents the production of harmful substances such as tar and nicotine, does not pollute the surrounding environment, and does not affect the health of smokers and those around them.

[0030] Due to these differences, an increasing number of users are now using cartridges 1 instead of traditional cigarettes to reduce the damage that traditional cigarettes cause to the user's body. The filter assembly 2 in the cartridge 1 typically filters out harmful substances and lowers the temperature of the smoke, preventing the smoke from becoming too hot and causing burns to the user's oral cavity when inhaling. However, the functions of the filter assembly 2 currently do not meet the increasing needs of users. For example, the flavor of current cartridges 1 is typically determined by the inherent odor of the smoke-generating material 60. Alternatively, the flavor of the cartridge 1 is achieved by adding an edible essence flavor to the smoke-generating material 60. However, factors such as the volume and capacity of the smoke-generating material 60 place certain limitations on the aroma, duration, and richness of the flavor.

[0031] Therefore, in order to solve the above problems, the present application provides a filter assembly 2. Please also refer to Figures 1 to 6. Figure 1 is a schematic diagram showing the three-dimensional structure of a filter assembly in one embodiment of the present application. Figure 2 is an exploded view of Figure 1. Figure 3 is a schematic diagram of a cross section taken along the AA direction in Figure 1. Figure 4 is a schematic diagram of a filter in one embodiment of the present application. Figure 5 is a schematic diagram of a functional material in one embodiment of the present application. Figure 6 is a schematic diagram of a functional material in another embodiment of the present application.

[0032] This embodiment provides a filter assembly 2. The filter assembly 2 includes a filter 70 and a functional material 30. An accommodation space 71 is provided in the radial direction of the filter 70. The functional material 30 is fixed within the accommodation space 71, and the filter 70 contacts a portion of the outer surface of the functional material 30.

[0033] The filter assembly 2 is primarily used to filter harmful substances in smoke and can also cool the smoke to prevent burns to the user's mouth. The filter assembly 2 provided in this embodiment generally includes a filter 70 and a functional material 30. Each component and the combination of components will now be described in detail.

[0034] The filter 70 is a main component of the filter assembly 2. The filter 70 can be used to filter harmful substances and further reduce the temperature of the smoke. Optionally, the material of the filter 70 includes, but is not limited to, food-grade polylactic acid (PLA), cellulose acetate, etc. Optionally, when the material of the filter 70 is polylactic acid, a pultrusion process can be used. Optionally, the axial length L5 of the filter 70 is 8 to 10 mm. The radial diameter d5 of the filter 70 is 6.5 to 7 mm.

[0035] A storage space 71 for storing the subsequent functional material 30 can be opened in the radial direction of the filter 70. The storage space 71 may be a groove or a hole, but is not limited to this in the present embodiment. When the storage space 71 is a hole, the filter 70 has a first surface 72 and a second surface 73 arranged back to back in the radial direction, and the storage space 71 penetrates the first surface 72 and the second surface 73. This can reduce the difficulty of opening the storage space 71. When the storage space 71 is groove In this case, the storage space 71 penetrates only the first surface 72 or the second surface 73, thereby preventing the functional material 30 from falling from the other surface. Note that this embodiment does not limit the shape of the storage space 71. In this embodiment, a schematic description is given of the storage space 71 penetrating both the first surface 72 and the second surface 73.

[0036] The functional material 30 is intended to achieve various functions; in other words, various functions can be achieved by utilizing the shape, structure, material, and other factors of the functional material 30. For example, if the material of the functional material 30 is a heat-absorbing material, such as metal or plastic, when smoke is transmitted to the functional material 30, the heat-absorbing material can absorb a large amount of heat, thereby enhancing the cooling effect. If the functional material 30 contains various flavorings, the functional material 30 can be used to change the flavor of the smoke and improve the quality, saturation, diversity, and persistence of the flavor. If the functional material 30 contains various Chinese or Western medicinal ingredients, the functional material 30 can be used to infuse the smoke with the various Chinese or Western medicinal ingredients, so that the user can inhale the various Chinese or Western medicinal ingredients into the mouth when inhaling, thereby providing health and therapeutic functions.

[0037] In this embodiment, the functional material 30 is merely used as a fragrance-enhancing material to change the odor of smoke. Optionally, the functional material 30 includes a housing 31 and a liquid or gaseous functional part 32 disposed within the housing 31, and the housing 31 abuts against the filter 70. The housing 31 can burst when subjected to a predetermined external force along the radial direction of the filter 70. The functional material 30 includes a housing 31 and a functional part 32 disposed within the housing 31, and the functional part 32 may be liquid or gaseous. The housing 31 abuts against and is fixed to the filter 70. The housing 31 can burst when subjected to a predetermined external force along the radial direction of the filter 70. For example, when a user pinches the filter 70 with their hands along the radial direction of the filter 70, the housing 31 can be crushed if the pressing force is greater than the predetermined external force. The housing 31 can be shattered, burst, or have a hole 83 formed therein, exposing the functional part 32 inside. In this case, the functional part 32 can move with the smoke as it passes through, and can also be moved by the user's inhalation force, so that the functional part 32 and the smoke can finally be inhaled into the user's mouth. The use of the functional material 30 can improve the user's taste and olfactory experience. Optionally, the functional material 30 can be formed by processes such as extrusion blow molding and canning.

[0038] Optionally, when the housing 31 bursts, the liquid functional part 32 can be adsorbed onto the filter 70. During the user's inhalation process, the smoke passing through the functional part 32 can be more easily drawn into the mouth, allowing the aroma to be more sustained from the filter cotton, improving the user's experience. Furthermore, the liquid or gas functional part 32 can also provide a certain degree of cooling effect.

[0039] Optionally, functional portion 32 contains edible-grade flavorings, including, but not limited to, one or more flavor formulations of fruit and vegetable flavors, such as blueberry, apple, watermelon, mango, and grape.

[0040] Alternatively, the shape of the functional material 30 may be spherical, ellipsoidal, or cylindrical. As shown in FIG. 5, when the functional material 30 is spherical, the diameter d3 of the functional material 30 is 3 to 4 mm. As shown in FIG. 6, when the functional material 30 is ellipsoidal or cylindrical, the outer diameter d3 of the functional material 30 in the radial direction D2 of the filter 70 is 3 to 4 mm, and the length L3 of the functional material 30 in the axial direction D1 of the filter 70 is 4 to 7 mm. All axial directions described below are represented by D1, and all radial directions are represented by D2. Because the filter 70 has a thickness, when the storage space 71 is formed in the filter 70, the filter 70 has an outer peripheral sidewall and an inner peripheral sidewall. The outer peripheral sidewall defines the exterior surface of the filter 70, and the inner peripheral sidewall forms the storage space 71. Therefore, the filter 70 has two radial dimensions: one is the dimension between the opposing sides of the outer peripheral sidewall (i.e., the outer diameter), and the other is the dimension between the opposing sides of the inner peripheral sidewall (i.e., the inner diameter). In other words, the size of the filter 70 in the radial direction between the opposing sides of the outer peripheral side wall is 3 to 4 mm. The same can be understood for the length, outer diameter, inner diameter, axial direction, and radial direction mentioned below in this application, and explanations thereof will be omitted in this application.

[0041] The filter assembly 2 provided in this embodiment can first enhance its cooling function by adding the functional material 30, or can increase the variety of functions of the filter assembly 2 by giving the filter 70 functions other than filtration, such as flavor enhancement, health care, and treatment, thereby improving the user's mouthfeel and vaping effect.

[0042] Next, the functional material 30 is fixed in the storage space 71 opened in the filter 70 and is in contact with the filter 70, thereby better fixing the functional material 30 within the filter 70 and preventing movement of the functional material 30 within the filter 70. Furthermore, since the functional material 30 comes into direct contact with the filter 70 when the user inhales, placing the functional material 30 within the filter 70 maximizes the suction force of the filter 70, further improving the performance and effectiveness of the functional material 30.

[0043] In addition, in the accommodation space 71 opened in the radial direction of the filter 70, Functional Materials 30 By fixing the filter 70 and the functional material 30 together, the difficulty of assembling the filter 70 and the functional material 30 can be reduced.

[0044] 3 , in this embodiment, the functional material 30 abuts against the side wall of the storage space 71. In this embodiment, the functional material 30 can be fixed to the filter 70 by abutting against the side wall of the storage space 71. Of course, in another embodiment, the functional material 30 can also be adhered to the side wall of the storage space 71.

[0045] 4 and 5 , in this embodiment, the filter 70 and the functional material 30 form an interference fit, and the ratio of the size d0 of the opening of the accommodation space 71 to the size of the functional material 30 in the axial direction of the filter 70 is (0.9-0.95:1). This ensures an appropriate interference between the filter 70 and the functional material 30, fixes the functional material 30 to the filter 70 within the above range, and ensures that the functional material 30 is not damaged. If the ratio of the size of the opening of the accommodation space 71 to the size of the functional material 30 in the axial direction of the filter 70 is too small, for example, less than 0.9:1, the accommodation space 71 is too small, and the inner diameter is too small, which may cause damage to the functional material 30. If the ratio of the size of the opening of the accommodation space 71 to the size of the functional material 30 in the axial direction of the filter 70 is too large, for example, greater than 0.95:1, the functional material 30 cannot be incorporated into the filter 70 with an interference fit.

[0046] 7 and 8, Fig. 7 is a schematic diagram of a filter assembly according to another embodiment of the present invention. Fig. 8 is an exploded view of Fig. 7. In this embodiment, a groove 74 is formed in the side wall, and a portion of the functional material 30 is provided in the groove 74.

[0047] In this embodiment, a recessed groove 74 is provided in the side wall based on an interference fit, and a part of the functional material 30 is provided in the recessed groove 74. By alleviating the pressing force due to the interference fit through the recessed groove 74, it is possible to prevent the filter from being pressed and deformed, which in turn causes other components such as the tubular body 40 to be deformed, ultimately resulting in an uneven shape. For example, it is possible to avoid the problem of the positions of the opposing ends of the filter 70 in the axial direction corresponding to the functional material becoming convex. , concave The presence of the grooves 74 can further limit the position of the functional material 30 within the filter 70, thereby improving the positional accuracy of the functional material 30 within the filter 70.

[0048] Of course, in another embodiment, the functional material 30 may be fixed to the filter 70 by adhering the functional material 30 to the sidewall of the filter 70 using adhesive or other methods.

[0049] Please refer to Figure 4 again. In this embodiment, the ratio of the size d0 of the opening of the accommodation space 71 to the size L5 of the filter 70 in the axial direction of the filter 70 is 1:(2.8 to 4).

[0050] In the axial direction of the filter 70, the ratio of the size of the opening of the storage space 71 to the length of the filter 70 is 1:(2.8 to 4). This ensures that the functional material 30 will not fall out of the storage space 71. It also prevents the filter 70 from being deformed by being pressed in the longitudinal direction, resulting in uneven end faces. If the opening of the storage space 71 is too large, not only will the functional material 30 not be able to be fixed, but the filter 70 will be too small, resulting in reduced functionality of the filter 70 itself. In other words, the longitudinal size of the filter 70 will be reduced, reducing its resistance to deformation. Therefore, when the functional material 30 is pressed in, the filter 70 will be pressed in the longitudinal direction, deforming both end faces of the filter 70 and becoming convex outward, potentially affecting its appearance and performance. If the opening of the storage space 71 is too small, the functional material 30 will be subjected to excessive pressure and repulsion after being installed in the storage space 71, which could result in damage to the functional material 30.
