Description

Technical Field

[0001] This utility model belongs to the technical field of cigarette holder filter cores, specifically referring to an integrated three-in-one spiral filter core for cigarette holders. Background Technology

[0002] Despite growing global calls for smoking bans, the number of smokers continues to rise year by year.

[0003] To minimize or reduce the amount of nicotine and tar entering the body, cigarette tips are usually made into filters. These built-in filters remove some harmful substances, but in practice, this has proven to be less than ideal, as more and more filter cartridges are being designed.

[0004] Currently, the filter cartridges on the market are simply spiral channels. The short contact time between the smoke and the filter cartridge results in a low tar filtration and adsorption rate. Furthermore, traditional filter cartridges require consumers to purchase filter cartridges with different slots separately for coarse, thin, and medium-sized cigarettes, which increases the purchase cost. Utility Model Content

[0005] This invention aims to at least solve the problems of low tar adsorption rate caused by the short contact time and small contact area between the smoke and the filter cartridges on the market, as well as the cost problem caused by the need to purchase filter cartridges of different sizes when smoking cigarettes of different thicknesses.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model proposes an integrated three-in-one spiral filter core for a cigarette holder, including a cylindrical filter tip for mounting the cigarette, the bottom of which has a stepped opening, and further comprising:

[0007] Smoke diverter: It is spirally wound around the circumferential wall of the filter tip and away from the opening, and is used to spirally divert the filtered smoke.

[0008] Cut-off groove: Symmetrically cuts off both sides of the flue gas diversion component, making it easier for the flue gas to rise along the flue gas diversion component;

[0009] Smoke outlet: It extends horizontally through the filter nozzle and is located at the cut-off groove.

[0010] As a preferred embodiment: the diameter of the lower half of the filter tip is larger than the diameter of the upper half, and the flue gas diverter is located in the upper half, and the gap formed between the flue gas diverter and the filter tip is in an ascending spiral shape.

[0011] As a preferred embodiment, the opening extends into the filter tip in a three-tiered stepped shape, and the smoke outlet is connected to it.

[0012] As a preferred embodiment, the filter tip is further provided with a positioning step on the circumferential surface near the opening at its lower end.

[0013] The beneficial effects of this utility model using the above structure are as follows: The integrated three-in-one spiral filter core for cigarette holders proposed in this solution not only physically filters tar, but also uses a smoke diversion component to spirally pressurize the smoke, so that the tar in the smoke is further spirally pressurized and comes into contact with the filter, thereby increasing the tar adsorption surface and allowing more tar to be adsorbed.

[0014] Furthermore, through its three-stage open design, it can effectively fix coarse, medium, and thin cigarettes, meeting the filtration requirements of 98% of coarse, medium, and thin cigarettes on the market, saving production and assembly costs, and achieving a more efficient filtration effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 , Figure 2 , Figure 3 :

[0021] The integrated three-in-one spiral filter core for cigarette holders includes a cylindrical filter 1 for mounting cigarettes, a stepped opening 2 at the bottom of the filter 1, and a positioning step 11 on the circumferential surface of the lower end of the filter 1 near the opening 2. It also includes: a smoke diverter 3, which is spirally wound around the circumferential wall of the filter 1 and located away from the opening 2. The diameter of the lower half of the filter 1 is larger than that of the upper half, and the smoke diverter 3 is located in the upper half. The gap formed between the smoke diverter 3 and the filter 1 is spirally upward, used for spirally diverting the filtered smoke; a cut-off groove 4, which symmetrically cuts off both sides of the smoke diverter 3 to facilitate the upward movement of smoke along the smoke diverter 3; and a smoke outlet 5, which transversely penetrates the filter 1 and is located at the cut-off groove 4. The opening 2 extends into the filter 1 in a three-step stepped manner, and the smoke outlet 5 communicates with it.

[0022] First, the filter tip 1 is installed in the carrier, which includes the mouthpiece, pipe, etc. The positioning step 11 clamps the filter tip 1 in place on the carrier. Then, thick, thin, and medium cigarette clips are inserted into the opening 2 as needed. The opening 2 is a three-stage stepped design that can clamp cigarettes of different thicknesses. When the user smokes, the smoke rises in the opening 2 and is discharged from the smoke outlet 5. It is then diverted along the cut-off groove 4 onto the spiral smoke diverter 3 and is pressurized by the spiral during the diversion process, increasing the contact time with the filter tip 1 and thus improving the amount of tar adsorption.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
