Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco product technology, and in particular to a filter tip fastener with a conical aerosol channel for heating 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] To address the limitations of existing technologies in allowing users to visually observe the aerosol agglomeration and misting process, this invention provides a filter tip for heated cigarettes with a conical aerosol channel that enables users to visually observe this process, as well as a heated cigarette including the filter tip with the conical aerosol channel.
[0005] A filter tip for heating cigarettes with a conical 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; An inlet is located on the end face near the smoke end, and the cross-sectional area of the outlet is larger than the cross-sectional area of the inlet; An aerosol channel is provided inside the filter body to connect the inlet and the outlet. The aerosol channel has a visible conical hole structure that gradually expands from the inlet to the outlet. Multiple protrusions are provided on the inner wall of the aerosol channel.
[0006] Furthermore, the shape of the protrusion structure is selected from one of the following: dot-shaped, tooth-shaped, or rib-shaped.
[0007] Furthermore, the number of inlets, outlets, and aerosol channels is consistent, ranging from 2 to 10.
[0008] Furthermore, the sum of the cross-sectional areas of the plurality of outlets accounts for no less than 20% of the cross-sectional area of the near-lip end.
[0009] Furthermore, the material of the filter body is selected from one of the following: silicone, polyarylate, or polypropylene.
[0010] Furthermore, the filter tip of the conical aerosol channel for heating cigarettes also includes a mesh structure, which is disposed at the front end of the inlet. The mesh structure includes multiple mesh holes, and the aperture of the mesh holes is smaller than the aperture of the inlet.
[0011] Furthermore, the mesh is square, and its side length is not less than 2mm.
[0012] Furthermore, the filter body is cylindrical with a circumference ranging from 17mm to 24mm.
[0013] On the other hand, the present invention also provides a heated cigarette, comprising a tobacco segment and a filter attachment for a conical aerosol channel for heated cigarettes as described in any of the above embodiments, which is connected to the tobacco segment.
[0014] Furthermore, the filter tip of the conical aerosol channel for heating cigarettes is connected to the tobacco segment by a splicing paper.
[0015] Compared with the prior art, the filter tip fastener of the conical aerosol channel for heated cigarettes provided in this embodiment of the present invention has at least the following technical effects: The filter element of the conical aerosol channel for heated cigarettes 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; the inlet is located on the end face near the smoke end, and the cross-sectional area of the outlet is larger than that of the inlet. The aerosol channel runs through the filter body, connecting the inlet and outlet. The aerosol channel has a visible conical hole structure that gradually expands from the inlet to the outlet, and multiple protrusions are provided on the inner wall of the aerosol channel. This design allows users to directly observe the aerosol agglomeration and misting process through the outlet, improving the user's inhalation experience. Furthermore, the visible conical hole structure design of the aerosol channel, which gradually expands from the inlet to the outlet, causes the aerosol to be dispersed at the inlet, forming smaller particle sizes and a higher number of aerosol molecules. Moreover, the design of multiple protrusions on the inner wall of the aerosol channel causes the aerosol to collide with the protrusions during flow, further refining the aerosol molecules and enhancing the aerosol agglomeration and misting effect.
[0016] Since the heated cigarette includes the filter element of the conical 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 conical aerosol channel for heated cigarettes according to the above embodiments, which will not be repeated here.

[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.

[0021] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly set on the other component; when a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.
[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 see the appendix Figure 1 To be continued Figure 4 As shown, one embodiment of this utility model provides a filter tip with a conical 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, and the cross-sectional area of the outlet 20 is larger than that of the inlet 30. 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 conical hole structure that gradually expands from the inlet 30 to the outlet 20, and multiple protrusions 41 are provided on the inner wall of the aerosol channel 40. It can be explained that the visible conical hole structure allows users to directly observe the aerosol agglomeration and misting process in the aerosol channel 40 with the naked eye, and its longitudinal cross-section is conical.
[0026] 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 conical aperture structure, users can directly observe the aerosol agglomeration and mist formation process through the outlet 20, enhancing the user's inhalation experience. Furthermore, the aerosol channel 40's design, with its gradually expanding visible conical aperture structure from the inlet 30 to the outlet 20, causes the aerosol to be dispersed at the inlet 30, forming smaller particle sizes and a higher number of aerosol molecules. Moreover, the design of multiple protruding structures 41 on the inner wall of the aerosol channel 40 allows the aerosol to collide with these structures during flow, further refining the aerosol molecules and enhancing the aerosol agglomeration and mist formation effect.
[0027] In this embodiment, the filter element of the conical 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 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, and the cross-sectional area of the outlet 20 is larger than that of the inlet 30. The aerosol channel 40 connects the inlet 30 and the outlet 20 inside the filter body 10. The aerosol channel 40 has a visible conical hole structure that gradually expands from the inlet 30 to the outlet 20, and multiple protrusions 41 are provided on the inner wall of the aerosol channel 40. This design allows users to intuitively observe the aerosol agglomeration and misting process through the outlet 20, improving the user's smoking experience. Furthermore, the aerosol channel 40 features a visible conical aperture structure that gradually expands from the inlet 30 to the outlet 20, causing the aerosol to be dispersed at the inlet 30, forming smaller particle sizes and a higher number of aerosol molecules. Moreover, the inner wall of the aerosol channel 40 is designed with multiple protrusions 41, allowing the aerosol to collide with these protrusions during flow, further refining the aerosol molecules and enhancing the aerosol's aggregation and mist-forming effect.
[0028] In some alternative embodiments, the shape of the protrusion structure 41 can be flexibly selected according to specific needs and design goals. Specifically, the shape of the protrusion structure 41 is selected from one of the following: dot-shaped, tooth-shaped, or rib-shaped.
[0029] In some alternative embodiments, the number of inlets 30, outlets 20, and aerosol channels 40 is the same, ranging from 2 to 10.
[0030] 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.
[0031] 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.
[0032] In some optional embodiments, the filter element of the conical 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.
[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 drawn into the inlet 30, 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 filter element of the conical aerosol channel for heated cigarettes according to any of the above embodiments, wherein the tobacco segment is connected to the filter element of the conical aerosol channel for heated cigarettes. Since the heated cigarette includes the filter element of the conical 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 conical aerosol channel for heated cigarettes according to the above embodiments, which will not be elaborated further here.
[0036] In some alternative embodiments, the filter tip of the conical aerosol channel for heated cigarettes is attached to the tobacco segment by a splice paper, thereby achieving 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.
