Novel graphene composite cigarette filter tip

Abstract

The invention provides a novel graphene composite cigarette filter tip. According to the technical scheme adopted for solving the technical problems, the novel graphene composite cigarette filter tip comprises a cigarette filter tip shell and a filter element. The cigarette filter tip shell comprises a cigarette holder area, a filtering area and a cigarette connector area. The filter element is arranged in the filtering area. A filter element fiber filtering segment and a grapheme adsorbing segment are sequentially arranged from the upper end of the cigarette holder area to the initial end of the cigarette connector area. The filtering area is characterized in that the filtering area is in threaded connection with the cigarette holder area and the cigarette connector area, and according to the contamination degree of the filtering area, the filtering area can be opened to replace the filter element at any time.

Description

technical field [0001] The invention relates to a cigarette filter, in particular to a novel graphene composite cigarette filter. Background technique [0002] Current cigarette filter devices generally use metal cooling methods to condense tar on the metal core. Some cigarette filter devices use acetate fibers to filter particulate matter in the smoke through physical collision capture, reducing the impact of smoke on smokers. hazards. [0003] Chinese patent CN202525068U describes a cigarette filter material made of fluoroplastic electret material, which is directly in contact with the tail of the cigarette. Due to the high temperature of the smoke of the cigarette, when the fluoroplastic electret is used in contact with the high-temperature smoke, it will decompose Produces gases harmful to humans. [0004] Chinese patent CN103919280A describes a cigarette filter. By setting a polypropylene electret filter layer in the cigarette filter, more than 90% of the smoke partic...

Problems solved by technology

[0004] Chinese patent CN103919280A describes a cigarette filter. By setting a polypropylene electret filter layer in the cigarette filter, more than 90% of the smoke particle pollutants are reduced, and then a photocatalyst filter layer is set in the cigarette filter, effectively reducing Hazardous substances such as nicotine, nitrosamines, and benzopyrene in the smoke reduce the harm to the body during the smoking process. However, when the polypropylene electret filter layer is in contact with high-temperature smoke, it will decompose and produce harmful substances. gas

[0005] Both of the above two technical solutions cannot absorb harmful gases such as ammonia and carbon monoxide produced in the smoking process, and need further improvement
