[0005] A filter tip fastener for heating cigarettes with a non-linear aerosol channel includes: 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 is provided inside the filter body to connect the inlet and the outlet. The aerosol channel has a visible porous structure, and the central axis of the aerosol channel is non-linear.
[0006] Furthermore, the central axis of the aerosol channel is one of the following: corrugated, spiral, or arc-shaped.
[0007] Furthermore, the number of inlets, outlets, and aerosol channels is the same, which is multiple, and the inlet and outlet connected to each aerosol channel are non-coaxially arranged.
[0008] Furthermore, the number of inlets, outlets, and aerosol channels are all three; The three inlets are evenly distributed at a circumferential angle of 120° on the end face near the smoke end, and the three outlets are evenly distributed at a circumferential angle of 120° on the end face near the lip end. Each of the aforementioned inlets is connected to the outlets arranged at a 120° angle above it via a corresponding aerosol channel; or, each of the aforementioned inlets is connected to the outlets arranged at a 240° angle above it via a corresponding aerosol channel.
[0009] Furthermore, the number of inlets, outlets, and aerosol channels are all four; The four inlets are evenly distributed at a 90° circumferential angle on the end face near the smoke end, and the four outlets are evenly distributed at a 90° circumferential angle on the end face near the lip end. Each of the aforementioned inlets is connected to the outlets arranged at a 90° angle to its upper surface through a corresponding aerosol channel; or, each of the aforementioned inlets is connected to the outlets arranged at a 180° angle to its upper surface through a corresponding aerosol channel.
[0010] 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.
[0011] Furthermore, the filter element for heated cigarettes with a non-linear aerosol channel also includes: 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.
[0012] Furthermore, the material of the filter body is selected from one of the following: silicone, polyarylate, or polypropylene.
[0013] Furthermore, the mesh is square, and its side length is not less than 2mm.
[0014] On the other hand, the present invention also provides a heated cigarette, comprising a tobacco segment and a filter attachment for a non-linear aerosol channel for heated cigarettes as described in any of the above embodiments, which is connected to the tobacco segment.
[0015] Compared with the prior art, the filter tip fastener with a non-linear aerosol channel for heated cigarettes and the heated cigarettes provided by this utility model have at least the following technical effects: The filter tip for heated cigarettes with a non-linear aerosol channel includes a filter body, an outlet, an inlet, and an aerosol channel. The filter body has a near-lip end and a near-smoke end along its axial direction. The outlet is located on the end face near the lip end, and 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. The aerosol channel has a visible perforated structure, and its central axis is non-linear.

[0020] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0022] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this application can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size should still fall within the scope of the technical content disclosed in this application, provided that they do not affect the effects and purposes that this application can produce.
[0023] 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.
[0024] 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.
[0025] Please refer to the attached document. Figure 1 To be continued Figure 9 As shown, one embodiment of this utility model provides a filter tip with a non-linear aerosol channel for heating cigarettes, including a filter tip body 10, an outlet 20, an inlet 30, and an aerosol channel 40. 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. The aerosol channel 40 has a visible perforated structure, and its central axis is non-linear, making the aerosol flow path from the inlet 30 to the outlet 20 a curved path. It can be explained that the visible perforated structure allows users to directly observe the aerosol agglomeration and misting process within the aerosol channel 40 with the naked eye.
[0026] It should be further explained that the aerosol channel 40 enables 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 non-linear design of the central axis of the aerosol channel 40 not only prevents users from directly seeing the tobacco when observing the outlet 20, but also allows them to clearly observe the aerosol agglomeration and misting process, further enhancing the user's vaping experience. Moreover, the non-linear design of the central axis of the aerosol channel 40 results in a curved flow path for the aerosols from the inlet 30 to the outlet 20. Compared to a straight path, this design lengthens the aerosol flow path, helping to reduce the aerosol temperature and improve its agglomeration and misting effect.
[0027] In this embodiment, the filter element with a non-linear aerosol channel for heated cigarettes includes a filter body 10, an outlet 20, an inlet 30, and an aerosol channel 40. The filter body 10 has a near-lip end 11 and a near-smoke end 12 along its axial direction. The outlet 20 is located on the end face of the near-lip end 11; the inlet 30 is located on the end face of the near-smoke end 12. The aerosol channel 40 connects the inlet 30 and the outlet 20 within the filter body 10. The aerosol channel 40 has a visible perforated structure, and its central axis is non-linear. This design allows users to visually observe the aerosol agglomeration and misting process through the outlet 20, while preventing direct viewing of the tobacco shreds, thus improving the user's smoking experience. Furthermore, the non-linear aerosol channel 40 extends the aerosol flow path, helping to lower the aerosol temperature and further enhancing the aerosol agglomeration and misting effect.
[0028] In some alternative embodiments, the central axis of the aerosol channel 40 can be designed in various different shapes to meet different usage requirements and user preferences. Specifically, the central axis of the aerosol channel 40 is one of the following: corrugated, spiral, or arc-shaped.
[0029] In some optional embodiments, the number of inlets 30, outlets 20 and aerosol channels 40 is the same, which is multiple, and the inlets 30 and outlets 20 connected to each aerosol channel 40 are non-coaxially arranged, that is, the inlets 30 and outlets 20 connected to each aerosol channel 40 do not coincide in the axial projection.
[0030] Please see the appendix Figure 4 As shown, in some optional embodiments, there are three inlets 30, three outlets 20, and three aerosol channels 40; the three inlets 30 are evenly distributed at a circumferential angle of 120° on the end face near the smoke end 12, and the three outlets 20 are evenly distributed at a circumferential angle of 120° on the end face near the lip end 11; each inlet 30 is connected to its corresponding outlet 20 arranged at a 120° angle above it through a corresponding aerosol channel 40; or, please refer to the appendix. Figure 5 As shown, each inlet 30 is connected to its outlet 20, which is arranged at a 240° angle above it, through a corresponding aerosol channel 40.
[0031] Please see the appendix Figure 8 As shown, in some optional embodiments, there are four inlets 30, four outlets 20, and four aerosol channels 40; the four inlets 30 are evenly distributed at a 90° circumferential angle on the end face near the smoke end 12, and the four outlets 20 are evenly distributed at a 90° circumferential angle on the end face near the lip end 11; each inlet 30 is connected to its corresponding aerosol channel 40 at a 90° angle above it; or, please refer to the appendix. Figure 9 As shown, each inlet 30 is connected to its outlet 20, which is arranged at a 180° angle above it, through a corresponding aerosol channel 40.
[0032] 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.
[0033] 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.
[0034] In some optional embodiments, the filter element of the non-linear aerosol channel for heated cigarettes further includes a mesh structure 50. The mesh structure 50 is disposed at the front end of the inlet 30 and includes multiple mesh openings, the diameter of which is smaller than the diameter of the inlet 30. The mesh structure 50 at the front end of the inlet 30 acts as a pre-interception layer, reducing the risk of blockage of the aerosol channel 40 due to tobacco entering it, and effectively preventing tobacco from being inhaled by the user, thereby improving safety and reliability.
[0035] 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.
[0036] 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 drawn into the inlet 30, the side length of the mesh should be smaller than the aperture of the inlet 30.
[0037] 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.
[0038] Furthermore, one embodiment of this utility model also provides a heated cigarette, including a tobacco segment and a filter element of the non-linear aerosol channel for heated cigarettes according to any of the above embodiments, wherein the tobacco segment is connected to the filter element of the non-linear aerosol channel for heated cigarettes. Since the heated cigarette includes the filter element of the non-linear aerosol channel for heated cigarettes according to any of the above embodiments, it at least possesses the technical effects of the filter element of the non-linear aerosol channel for heated cigarettes according to the above embodiments, which will not be elaborated further here.
[0039] In some alternative embodiments, the filter tip for the non-linear aerosol channel of the heated cigarette is attached to the tobacco segment by a splice paper, thereby achieving a quick and reliable coaxial assembly.
[0040] 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.
