Abstract

The utility model provides a cigarette filter tip, which includes a piece of winding paper outside and a fiber material body encapsulated by the winding paper. The fiber material body includes two sections, wherein the inner of a section of fiber material body close to cut tobacco is provided with activated carbon, and the winding paper close to a mouth extends outwards to form a hollow pipe. So the utility model has the advantages of reasonable design, convenient operation, effectively filtrating for harmful substances in the smoke of cigarettes, such as tar, nicotine, nicotine, carbon monoxide, etc., and avoiding occurrence of xanthodont appearance.

Description

Cigarette filter

Technical field

The utility model relates to cigarette, particularly a kind of cigarette filter.

Background technology

Existing in the market cigarette filter is used for the material of filter cigarette, it is arranged on the cigarette end, it comprises outside coil paper and parcel whole section fibrous material body within it, though the cigarette filter of this kind structure has played material effect in the filter cigarette, and prevent that pipe tobacco from directly contacting the purpose of population, but harmful substances such as the tar that contains in the cigarette smoke, nicotine, nicotine, carbon monoxide can not effectively be filtered out, so need develop the cigarette filter of harmful substance in a kind of effectively filter cigarette flue gas newly.

Summary of the invention

The purpose of this utility model is the defective at above-mentioned prior art, and the cigarette filter of harmful substance in a kind of effectively filter cigarette flue gas is provided.

The technical scheme taked of the utility model is to achieve these goals: a kind of cigarette filter, comprise outside coil paper and parcel fibrous material body within it, described fibrous material body is two sections, wherein one section fibrous material body inside near pipe tobacco is provided with active carbon, and described coil paper is near the formation blank pipe that stretches out of population one end.

The coil paper thickness of described blank pipe part is greater than pipe tobacco coil paper thickness.

The beneficial effects of the utility model are: compared to existing technology, the utlity model has the advantage of harmful substance in the effective filter cigarette flue gas.

Description of drawings

Fig. 1 is an overall structure schematic diagram of the present utility model.

Among the figure: 1 pipe tobacco, 2 pipe tobacco coil papers, 3 activated carbon fiber material bodies, 4 fibrous material bodies, 5 blank pipes, 6 coil papers.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.

A kind of cigarette filter as shown in Figure 1 comprises outside coil paper 6 and is wrapped in its fibrous material body 4 in 6.In order to make cigarette filter reach reasonable in design, and the effective purpose of filtering out harmful matter, described fibrous material body 4 is two sections, wherein a section near pipe tobacco 1 is that activated carbon fiber material body 3, another section are fibrous material body 4, and activated carbon fiber material body 3 is at the fibrous material body 4 inner active carbons that add particulate.Because active carbon has very strong adsorption capacity, thus it harmful substances such as the tar in the flue gas, nicotine, nicotine, carbon monoxide effectively can be absorbed, thereby alleviate the harm of smoking greatly to human body.Because the tar in the cigarette can be bonded in filter-tip end by the air-flow of inhaling when people's smoking, thereby be adsorbed on people's the tooth, on tooth, cause cigarette stain tooth (being commonly called as " xanthodont "), and then enter in the human body, for fear of the generation of this phenomenon, described coil paper 6 forms blank pipe 5 near stretching out of population one end.

Blank pipe 5 place's coil papers 6 are involute when preventing smoking influences the smoking effect, and coil paper 6 thickness of described blank pipe 5 parts are greater than the thickness of pipe tobacco coil paper 2.

Therefore the utlity model has reasonable in design, easy to use, effective harmful substances such as the tar in the filter cigarette flue gas, nicotine, nicotine, carbon monoxide, and avoid the advantage of xanthodont phenomenon generation.

Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.

Claims

1. cigarette filter, comprise outside coil paper and parcel fibrous material body within it, it is characterized in that: described fibrous material body is two sections, and wherein one section fibrous material body inside near pipe tobacco is provided with active carbon, and described coil paper is near the formation blank pipe that stretches out of population one end.

2. by the described cigarette filter of claim 1, it is characterized in that: the coil paper thickness of described blank pipe part is greater than pipe tobacco coil paper thickness.
