Description

Technical Field

[0001] The utility model relates to the technical field of tobacco products, and particularly relates to a cigarette filter tip. Background Art

[0002] At present, most cigarette filter tips are based on diacetate cellulose, and their filtering effect on harmful substances is limited. Although they can filter the smoke components and reduce the inhalation amount of tar and nicotine to a certain extent, the filtering effect of the filter tip is not very obvious, and most of the tar and nicotine are still inhaled into the human body, causing harm to the human body. The water pipe can remove more harmful substances by filtering the smoke through water, but it is not convenient to carry. Content of the Utility Model

[0003] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the utility model is: how to provide a cigarette filter tip and a cigarette with a clever structural design that can filter the smoke with water.

[0004] To solve the above technical problem, the utility model adopts the following technical scheme:

[0005] A cigarette filter tip, characterized in that it includes a columnar filter tip body, a water filtering component is arranged in the filter tip body, the water filtering component includes a columnar filtering container, the filtering container is provided with a smoke passing channel respectively communicating with the front end and the rear end of the filter tip body, a waterproof and breathable membrane is covered on the smoke passing channel, and a liquid for filtering the smoke is loaded in the filtering container.

[0006] With the above structure, when sucking through the filter tip body, the smoke will pass through the waterproof and breathable membrane from the front end of the filter tip body and enter the container, and pass through the waterproof and breathable membrane on the other side channel. Since the container is loaded with a liquid that can filter the smoke, the adsorption and filtration of the smoke can be realized. The structure is designed cleverly and can filter the smoke with water to achieve the effect of a water pipe.

[0007] Further, two waterproof and breathable membranes are arranged side by side along the length direction of the filter tip body, and the edges of the two waterproof and breathable membranes are hermetically connected to form the filtering container.

[0008] In this way, the thickness between the two waterproof and breathable membranes can be shortened, so that the smoke can penetrate better.

[0009] Further, at least one inner side of the waterproof and breathable membrane is filled with a breathable water-absorbing material, and the volume of the liquid loaded in the filtering container is less than the volume of the filtering container.

[0010] In this way, since the water-absorbing material is filled inside the waterproof and breathable membrane, after the liquid is adsorbed by the water-absorbing material, it can evenly cover the waterproof and breathable membrane. When the smoke passes through the waterproof and breathable membrane, it will pass through the gaps between the water-absorbing materials and contact the liquid adsorbed on the water-absorbing materials. Since the waterproof and breathable membrane only allows gas to pass through, the liquid will be retained in the filtering container.

[0011] Furthermore, the filtering container includes a cylindrical barrel body, and through holes for the smoke to pass through are formed through both ends of the barrel body.

[0012] Furthermore, an annular partition protruding radially is provided on the barrel body, and the diameter of the annular partition is the same as the diameter of the filter tip body; a plurality of filtering holes are provided on the outer circumferential surface of the barrel body, and the waterproof and breathable membranes are all coated thereon.

[0013] In this way, the area outside the filter tip body is separated by the annular partition, so that the smoke can only flow through the filtering container. By providing a plurality of filtering holes on the outer circumferential surface of the barrel body, the overall filtering area can be increased, thereby increasing the air permeability.

[0014] Furthermore, the annular partition is located in the middle of the container.

[0015] In this way, the areas of the air inlet end and the air outlet end of the filtering container can be increased, thereby increasing the air permeability.

[0016] Furthermore, the barrel body includes support rods arranged axially, a plurality of support rods are evenly distributed circumferentially, and an annular rib extending circumferentially is connected between the plurality of support rods; the gaps between the support rods and the annular rib form the filtering holes.

[0017] Furthermore, the water-absorbing material is a sponge filled in the filtering container.

[0018] Furthermore, the volume of the liquid is 1 / 3 to 2 / 3 of the volume of the filtering container.

[0019] A cigarette, characterized in that it includes a tobacco section and the cigarette filter tip as described above.

[0020] In summary, the cigarette filter tip and the cigarette of the present utility model both have the advantages of ingenious structural design and being able to perform water filtration on the smoke. Description of the Drawings

[0022] Figure 2 It is a schematic overall structure diagram of the barrel body.

[0023] Figure 3It is a schematic cross-sectional structure diagram of a water filter component. Specific embodiments

[0024] The following further elaborates on the present utility model in conjunction with embodiments.

[0025] During specific implementation: As Figure 1 and Figure 2 shown, a cigarette filter includes a columnar filter body 1. A water filter component 2 is disposed inside the filter body 1. The water filter component 2 includes a columnar filtering container 21. The filtering container 21 has smoke passing channels 22 respectively communicating with the front end and the rear end of the filter body 1. A waterproof and breathable membrane 23 covers the smoke passing channels 22. An air-permeable water-absorbing material 24 is filled inside at least one of the waterproof and breathable membranes 23. A liquid for filtering smoke is loaded inside the filtering container 21, and the volume of the liquid is less than the volume of the filtering container 21.

[0026] Specifically, the filtering container 21 includes a cylindrical barrel body. The two ends of the barrel body are formed with the smoke passing channels 22 in a penetrating manner. To improve the air permeability of the waterproof and breathable membrane, the barrel body has an annular partition protruding radially. The diameter of the annular partition is the same as the diameter of the filter body 1. A plurality of filtering holes (not shown in the figure) are formed on the outer cylindrical surface of the barrel body, and all are covered with the waterproof and breathable membrane 23. As Figure 2 shown, the annular partition is located in the middle of the container. The area outside the filter body is separated by the annular partition, so that the smoke can only flow through the filtering container. By providing a plurality of filtering holes on the outer cylindrical surface of the barrel body, the overall filtering area can be increased, thereby increasing the air permeability.

[0027] During specific implementation, the air holes can be directly opened on the surface of the barrel body, or can be formed by the following structure: The barrel body includes support rods arranged along the axial direction. A plurality of the support rods are evenly distributed along the circumferential direction, and an annular rib extending along the circumferential direction is connected between the plurality of support rods. The gaps between the support rods and the annular rib form the filtering holes.

[0028] In this embodiment, the filter body 1 is filled with a composite fiber bundle, and the water-absorbing material 24 is a sponge filled in the filter container 21, and the sponge completely fills the inner cavity of the filter container 21. The volume of the liquid is 1 / 3 to 2 / 3 of the volume of the filter container 21, and the liquid can be selected from pure water or an aqueous solution of edible ethanol. In this way, since the volume of the liquid is less than the volume of the filter container, there is still a space for air circulation in the filter container. The sponge adsorbs and disperses the liquid into the entire space of the filter volume under the action of water absorption. The smoke generated during cigarette smoking enters the filter container through the waterproof and breathable membrane. After being filtered by the water in the sponge area, it passes through the waterproof and breathable membrane on the other side, thereby realizing the water filtration of the smoke and achieving the effect of a water pipe.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
