Description

Technical Field

[0001] This utility model relates to the field of filter tip technology, and in particular to a fiber filter tip. Background Technology

[0002] Fiber filters are an important component of cigarettes, reducing harmful substances in smoke through physical interception and adsorption. Their materials, structure, and working principle are crucial to filtration effectiveness and user experience. External cigarette filters also utilize fiber components. Currently, external fiber filters have a fixed nozzle diameter, making it difficult to adjust the smoke output diameter. This makes it challenging to adjust the smoke output speed according to different users' preferences for smoke concentration (e.g., beginners prefer milder smoke, while experienced smokers prefer stronger smoke), thus impacting the user experience. Utility Model Content

[0003] This invention provides a fiber filter tip that solves the problems in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fiber filter tip includes a filter tip body, wherein a first filter layer, a second filter layer and a third filter layer are sequentially disposed inside the filter tip body.

[0006] The filter nozzle body has a rotating rod inside, and the surface of the rotating rod is provided with a circular baffle. The two ends of the rotating rod pass through the filter nozzle body and are respectively connected to a nut and a knob.

[0007] As a further description of the above technical solution:

[0008] The diameter of the baffle is the same as the inner diameter of the filter body.

[0009] As a further description of the above technical solution:

[0010] The nut is in contact with the surface of the filter body.

[0011] As a further description of the above technical solution:

[0012] The first filter layer is a high-density fiber layer, the second filter layer is a functionalized fiber layer, and the third filter layer is a low-density fiber layer.

[0013] As a further description of the above technical solution:

[0014] The surface of the filter nozzle body is provided with an annular plate, and a protective cover for protecting the filter nozzle body is connected to the surface of the annular plate.

[0015] As a further description of the above technical solution:

[0016] The bottom of the protective cover is connected to a locking block, and the top of the annular plate is provided with a locking groove that engages with the locking block.

[0017] As a further description of the above technical solution:

[0018] The inner wall of the protective cover is lined with cleaning cotton.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] In this invention, the position of the circular baffle inside the filter can be changed by rotating the knob, thereby adjusting the cross-sectional area of ​​the airflow channel. When the gap between the baffle and the inside of the filter increases, the smoke flow rate increases and the taste becomes stronger; when the gap decreases, the flow rate decreases and the taste becomes milder. This adjustment method can meet the personalized needs of different users for smoke concentration and enhance the satisfaction of smoking. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2A fiber filter tip includes a filter tip body 1. Inside the filter tip body 1, a first filter layer 2, a second filter layer 3, and a third filter layer 4 are arranged sequentially. A rotating rod 5 is rotatably arranged inside the filter tip body 1, and a circular baffle 6 is provided on the surface of the rotating rod 5. The two ends of the rotating rod 5 pass through the filter tip body 1 and are respectively connected to a nut 8 and a knob 7. By rotating the knob 7, the rotating rod 5 can drive the baffle 6 to rotate inside the filter tip body 1, and the gap between the baffle 6 and the inner wall of the filter tip body 1 can be adjusted to adjust the smoke output speed of the filter tip body 1. It can be adjusted according to personal usage habits.

[0027] Furthermore, the diameter of the baffle 6 is the same as the inner diameter of the filter body 1, which can avoid a large gap between them, resulting in a small change in suction resistance after adjustment, which is difficult to meet the requirements.

[0028] Furthermore, the nut 8 is in contact with the surface of the filter body 1, which is to increase the friction of the rotating rod 5 and prevent the rotating rod 5 from rotating under large external forces.

[0029] Furthermore, the first filter layer 2 is a high-density fiber layer, the second filter layer 3 is a functional fiber layer, and the third filter layer 4 is a low-density fiber layer. The high-density fiber layer is a cellulose acetate layer, which mainly intercepts large particles. The functional fiber layer can be an activated carbon fiber layer, a sepiolite fiber layer, or a rush fiber layer, which mainly adsorbs harmful gases. The low-density fiber layer can be a plant fiber filter layer or a polypropylene fiber layer, which mainly adjusts the suction resistance and taste.

[0030] Furthermore, an annular plate 9 is provided on the surface of the filter body 1, and a protective cover 10 for protecting the filter body 1 is connected to the surface of the annular plate 9. The protective cover 10 can protect the filter body 1 from contact with the user's mouth, preventing external dust or bacteria from adhering to the surface of the filter body 1 when not in use.

[0031] Furthermore, the bottom end of the protective cover 10 is connected to a locking block 11, and the top end of the annular plate 9 is provided with a locking groove that engages with the locking block 11. By engaging the locking block 11 with the locking groove, the protective cover 10 can be installed on the surface of the filter nozzle body 1 to protect it.

[0032] Furthermore, the inner wall of the protective cover 10 is provided with cleaning cotton. When the protective cover 10 is connected to the surface of the filter body 1, the cleaning cotton on its inner wall can clean the surface of the filter body 1 to a certain extent.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
