Abstract

The utility model relates to the field of cigarette filtration, in particular to a cigarette filter tip, and solves the problem that the existing cigarette filter device is poor in filtering effect and may produce harmful gas. The cigarette filter tip comprises a cigarette filter tip shell; the cigarette filter tip shell comprises a smoking area, a filter area and a cigarette area; a photocatalyst-free filter layer and a polypropylene electret filter layer are disposed in the filter area sequentially from the tail end of the smoking area to the start end of the smoking area III. The polypropylene electret filter layer is disposed in the cigarette filter tip, and smoke particulate pollutant is decreased by more than 90%; the photocatalyst-free filter layer is also disposed in the cigarette filter tip, harmful matters in smoke, such as nicotine, nitrosamine and benzopyrene, are reduced effectively, and harm to the body during smoking is reduced; meanwhile, a smoker never sees the smoke when blowing out the smoke, and environmental pollution by the smoke is improved effectively. The cigarette filter tip is applicable to the field of cigarette filter tips.

Description

Cigarette filter

Technical field

The utility model relates to cigarette filter field.

Background technology

Current cigarette filter, generally all adopt the cooling method of metal tar to be condensed on the core body of metal, part cigarette filter adopts acetate fiber, and the method catching by physical impacts is filtered the particle in flue gas, reduces the harm of flue gas to smoker.

Chinese patent CN 202525068U has described the cigarette filter material that a kind of fluoroplastics electret is made, directly contact with cigarette afterbody, because the flue-gas temperature of cigarette is higher, while using fluoroplastics electret to contact with high-temperature flue gas, can decompose and produce the gas being pernicious to people.

Utility model content

For solving the problems of the technologies described above, the utility model provides cigarette filter.

The utility model solves the technical scheme that its technical problem adopts: cigarette filter, comprises cigarette filter shell; Described cigarette filter shell comprises smoking seat, filtering area and cigarette district; Top from the end of smoking seat to cigarette district in described filtering area is disposed with without photocatalyst filter course and polypropylene electret filter course.

Described filtering area adopts one or more polypropylene electret filter courses.

The cross section of the filtering area of described cigarette filter shell and the inwall in cigarette district is circular.

The cross section of the outer wall of described cigarette filter shell is one or more the combination in circular, square and polygon.

Described is cylindrical without photocatalyst filter course, and with the inwall close contact of the filtering area of cigarette filter shell.

Described polypropylene electret filter course is cylindrical, and with the inwall close contact of the filtering area of cigarette filter shell.

Operation principle: cigarette smoke enters into filtering area from cigarette district, through polypropylene electret filter course, filter out most flue gas particle pollutant, then, cigarette smoke process is without photocatalyst filter course, filter out the harmful substances such as most nicotine, nitrosamine, BaP, last, cigarette smoke enters smoker's oral cavity by smoking seat; Greatly reduce the harm of cigarette smoke to health in smoking process, the efficiency that the number of plies of increase or minimizing polypropylene electret filter course can change filtration is to meet different crowd to healthy needs.

The beneficial effects of the utility model: cigarette filter of the present utility model, by be provided with polypropylene electret filter course in cigarette filter, reduced more than 90% flue gas particle pollutant, in cigarette filter, arrange again without photocatalyst filter course, effectively reduce the harmful substances such as nicotine in flue gas, nitrosamine, BaP, reduced the harm to health in smoking process, simultaneously, smoker cannot see cigarette when telling cigarette, can effectively improve the pollution of flue gas to environment.

Accompanying drawing explanation

Fig. 1 is the schematic internal view of the cigarette filter of embodiment mono-;

Wherein, I-smoking seat, II-filtering area, III-cigarette district, 1-is without photocatalyst filter course, 2-polypropylene electret filter course.

The specific embodiment

In order to deepen, to understanding of the present utility model, below in conjunction with drawings and Examples, the utility model to be described in further detail, this embodiment, only for explaining the utility model, does not form and limits protection domain of the present utility model.

Embodiment

Cigarette filter, comprises cigarette filter shell, and described cigarette filter shell comprises smoking seat I, filtering area IIHe cigarette district III; Top from the end of smoking seat I to cigarette district III in described filtering area II is disposed with without photocatalyst filter course 1 and polypropylene electret filter course 2; Described filtering area II adopts two polypropylene electret filter courses 2; The cross section of the inwall of the filtering area IIHe cigarette district III of described cigarette filter shell is circular; The cross section of the outer wall of described cigarette filter shell is one or more the combination in circular, square and polygon; Described is cylindrical without photocatalyst filter course 1, and with the inwall close contact of the filtering area II of cigarette filter shell; Described polypropylene electret filter course 2 is cylindrical, and with the inwall close contact of the filtering area II of cigarette filter shell.

Operation principle: cigarette smoke enters into filtering area II from cigarette district III, through polypropylene electret filter course 2, filter out most flue gas particle pollutant, then, cigarette smoke process is without photocatalyst filter course 1, filter out the harmful substances such as most nicotine, nitrosamine, BaP, last, cigarette smoke enters smoker's oral cavity by smoking seat I; Greatly reduce the harm of cigarette smoke to health in smoking process, the efficiency that the number of plies of increase or minimizing polypropylene electret filter course 2 can change filtration is to meet different crowd to healthy needs.

Above-described embodiment should not limit the utility model by any way, and all employings are equal to replaces or technical scheme that the mode of equivalence conversion obtains all drops in protection domain of the present utility model.
