Technical Field
[0001] This utility model relates to the field of tobacco product technology, and in particular to a filter tip for heated cigarettes and a heated cigarette. Background Technology
[0002] Traditional cigarette filters often use cellulose acetate bundles as the core filter material. The gaps between the cellulose acetate bundles are small, which means that users cannot directly observe the aerosol formation and misting process during the entire smoking process. They can only passively feel the final smoke at the outlet, resulting in a poor smoking experience.
[0003] Therefore, how to enable users to intuitively observe the aerosol agglomeration and fog formation process has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0004] This invention addresses the issue of how existing technologies allow users to visually observe the aerosol agglomeration and misting process. It provides a heated cigarette filter holder that enables users to visually observe this process, as well as a heated cigarette including the filter holder.
[0005] A filter tip for heating cigarettes, comprising: The filter body has a lip end and a smoke end along its axial direction; The outlet is located on the end face near the lip end; The inlet is located on the end face near the smoke end; An aerosol channel connects the inlet and the outlet inside the filter body, and the aerosol channel has a visible pore structure. A mesh structure is provided at the front end of the inlet, the mesh structure comprising a plurality of mesh openings, the aperture of which is smaller than the aperture of the inlet.
[0006] Furthermore, the number of inlets, outlets, and aerosol channels is consistent, consisting of multiple channels.
[0007] Furthermore, the total cross-sectional area of the plurality of inlets accounts for no less than 20% of the cross-sectional area near the smoke end; And / or, the sum of the cross-sectional areas of the plurality of said outlets accounts for not less than 20% of the cross-sectional area of the near-lip end.
[0008] Furthermore, the number of inlets, outlets, and aerosol channels is consistent, ranging from 2 to 10. Furthermore, the inner wall of the aerosol channel has a smooth surface.
[0009] Furthermore, the material of the filter body is selected from one of the following: silicone, polyarylate, or polypropylene.
[0010] Furthermore, the mesh is square, and its side length is not less than 2mm.
[0011] Furthermore, the filter body is cylindrical with a circumference ranging from 17mm to 24mm.
[0012] On the other hand, the present invention also provides a heated cigarette, comprising a tobacco segment and a filter tip for heated cigarette as described in any of the above embodiments, which is attached to the tobacco segment.
[0013] Furthermore, the filter tip for heated cigarettes is connected to the tobacco segment via a splicing paper.
[0014] Compared with the prior art, the heated cigarette filter firmware provided in this embodiment of the present invention has at least the following technical effects: The heated cigarette filter includes a filter body, an outlet, an inlet, an aerosol channel, and a mesh structure. The filter body has a lip-like end and a smoke-like end along its axial direction. The outlet is located on the end face near the lip end; the inlet is located on the end face near the smoke end. The aerosol channel runs through the filter body, connecting the inlet and outlet, and is a visible perforated structure. The mesh structure is located at the front end of the inlet, and includes multiple mesh openings with a smaller aperture than the inlet opening. This design allows users to visually observe the aerosol agglomeration and misting process through the outlet, thus improving the user's vaping experience. Furthermore, by setting a mesh structure at the front end of the inlet and ensuring the mesh openings are smaller than the inlet opening, the risk of blockage in the aerosol channel due to tobacco entering the channel is reduced, and tobacco is effectively prevented from being inhaled by the user, thereby improving safety and reliability.

[0022] Traditional cigarette filters often use cellulose acetate bundles as the core filter material. The gaps between the cellulose acetate bundles are small, which means that users cannot directly observe the aerosol formation and misting process during the entire smoking process. They can only passively feel the final smoke at the outlet, resulting in a poor smoking experience.
[0023] Therefore, how to enable users to intuitively observe the aerosol agglomeration and fog formation process has become a technical problem that urgently needs to be solved by those skilled in the art.
[0024] Please refer to the attached document. Figure 1 To be continued Figure 4As shown, one embodiment of this utility model provides a filter tip for heated cigarettes, including a filter tip body 10, an outlet 20, an inlet 30, an aerosol channel 40, and a mesh structure 50. The filter tip body 10 has a lip end 11 and a smoke end 12 along its axial direction. The outlet 20 is located on the end face of the lip end 11; the inlet 30 is located on the end face of the smoke end 12; the aerosol channel 40 connects the inlet 30 and the outlet 20 within the filter tip body 10, and the aerosol channel 40 has a visible perforated structure; the mesh structure 50 is located at the front end of the inlet 30, and the mesh structure 50 includes multiple mesh openings, the diameter of which is smaller than the diameter of the inlet 30. It can be explained that the visible perforated structure allows users to directly observe the aerosol agglomeration and misting process in the aerosol channel 40 with the naked eye.
[0025] It should be further explained that the aerosol channel 40 enables the directional delivery of aerosols from the near-smoke end 12 to the near-lip end 11. Because the aerosol channel 40 is a continuous, visible perforated structure, users can directly observe the aerosol agglomeration and misting process through the outlet 20, enhancing the user's vaping experience. Furthermore, the mesh structure 50 at the front end of the inlet 30 serves as a pre-interception layer, not only reducing the risk of blockage in the aerosol channel 40 due to tobacco entering it, but also effectively preventing tobacco from being inhaled by the user, thereby improving safety and reliability.
[0026] In this embodiment, the heated cigarette filter includes a filter body 10, an outlet 20, an inlet 30, an aerosol channel 40, and a mesh structure 50. The filter body 10 has a lip end 11 and a smoke end 12 along its axial direction. The outlet 20 is located on the end face of the lip end 11. The inlet 30 is located on the end face of the smoke end 12. The aerosol channel 40 runs through the filter body 10, connecting the inlet 30 and the outlet 20, and the aerosol channel 40 has a visible perforated structure. The mesh structure 50 is located at the front end of the inlet 30 and includes multiple mesh holes, the diameter of which is smaller than the diameter of the inlet 30. This design allows users to visually observe the aerosol agglomeration and misting process through the outlet 20, thereby improving the user's smoking experience. Furthermore, by setting a mesh structure 50 at the front end of the inlet 30, and setting the mesh aperture to be smaller than the inlet 30 aperture, not only is the risk of the aerosol channel 40 being blocked due to tobacco entering the aerosol channel 40 reduced, but the tobacco is also effectively prevented from being inhaled by the user, thereby improving the safety and reliability of use.
[0027] In some optional embodiments, the number of inlets 30, outlets 20, and aerosol channels 40 is the same, which is multiple. Optionally, each inlet 30 and outlet 20 is arranged opposite to the filter body 10 in the axial direction. In this embodiment, by setting multiple aerosol channels 40, the aerosol can be effectively diverted, thereby effectively reducing the aerosol flow rate, promoting the aerosol to clump and form mist within the aerosol channels 40, and thus improving the aerosol clumping and misting effect.
[0028] In some alternative embodiments, the total cross-sectional area of the multiple inlets 30 accounts for no less than 20% of the cross-sectional area of the near-smoke end 12, thereby enabling the near-smoke end 12 to have a sufficient effective open area so that the aerosol can effectively enter the aerosol channel 40 to form a cluster and mist.
[0029] In some optional embodiments, the total cross-sectional area of the multiple outlets 20 accounts for no less than 20% of the cross-sectional area of the near-lip end 11, thereby giving the near-lip end 11 a sufficient effective open area, allowing the user to intuitively observe the aerosol agglomeration and misting phenomenon, thereby improving the user's suction experience.
[0030] In some alternative embodiments, the number of inlets 30, outlets 20, and aerosol channels 40 is the same, ranging from 2 to 10.
[0031] In some alternative embodiments, the inner wall of the aerosol channel 40 is a smooth surface, thereby effectively reducing the amount of aerosol trapped in the aerosol channel 40 and allowing the aerosol to flow smoothly.
[0032] In some alternative embodiments, the filter body 10 is preferably made of a material with good heat insulation properties to effectively prevent burns to the lips. Specifically, it is selected from one of the following: silicone, polyarylate, or polypropylene.
[0033] In some alternative embodiments, the mesh is square with a side length of not less than 2 mm to ensure that the aerosol can effectively enter the aerosol channel 40. However, to reduce the risk of tobacco clogging the aerosol channel 40 and to reduce the possibility of tobacco being inhaled, the side length of the mesh should be smaller than the aperture of the inlet 30.
[0034] In some alternative embodiments, the filter body 10 is cylindrical with a circumference ranging from 17 mm to 24 mm, which facilitates compatibility with mainstream tobacco segments, tipping paper, and existing tipping equipment, thereby effectively reducing retrofit costs.
[0035] Furthermore, one embodiment of this utility model also provides a heated cigarette, including a tobacco segment and a heated cigarette filter fixture as described in any of the above embodiments, wherein the tobacco segment and the heated cigarette filter fixture are connected together. Since the heated cigarette includes the heated cigarette filter fixture as described in any of the above embodiments, it at least possesses the technical effects of the heated cigarette filter fixtures described in the above embodiments, and will not be elaborated further here.
[0036] In some alternative embodiments, the filter tip for heated cigarettes is attached to the tobacco segment via a splice paper, thereby enabling quick and reliable coaxial assembly.
[0037] The above description is merely an embodiment of this utility model. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this utility model, but these improvements all fall within the protection scope of this utility model.
