Description

Cigarette filter

Technical field:

The utility model relates to a kind of cigarette filter.

Background technology:

Cigarette is a kind of harmful substance, smoke contains harmful substances such as a large amount of nicotines, tar, filter-tip is generally single layer structure at present, promptly directly packing filtering bodies by filter-tipped packing paper forms, filtering bodies generally adopts the silk tree, and this design exists poor filtration effect, and the amount of substances such as tar that actual filtration is fallen seldom, a large amount of harmful materials still are inhaled in the human body, and health is damaged.

Summary of the invention:

The purpose of this utility model is to provide a kind of cigarette filter of simple in structure, the harmful substance that can more filtering cigarette combustion produces.The purpose of this utility model is achieved in that it is made up of filter-tipped packing paper and filtering bodies, and filtering bodies is a three-decker, promptly takes off the cotton layer of paper I, activated carbon layer, takes off the cotton layer of paper II.The utility model has the advantages that:, the harmful substance major part in the smog has been stayed in the absorbent cotton, thereby protected smoker's health better because filtering bodies mainly is to have adopted absorbent cotton that smog is filtered.In addition, activated carbon layer also can further guarantee filter effect.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Reference numeral: 1, filter-tipped packing paper, 2, filtering bodies, 3, take off the cotton layer of paper I, 4, activated carbon layer, 5, take off the cotton layer of paper II.

The specific embodiment:

Embodiment: it packs filtering bodies 2 by filter-tipped packing paper 1 the utility model, and constitutes one with the smoke that contains pipe tobacco, and filtering bodies is a three-decker, promptly takes off the cotton layer of paper I3, activated carbon layer 4, takes off the cotton layer II5 of paper.

Operation principle of the present utility model is: during smoking, smog by degreasing cotton layer I3, active carbon layer 4 in the filtering bodies, take off the cotton layer of paper II5 and filter the back and suck human body.Because the filtration of two layers of absorbent cotton has been stayed in the absorbent cotton harmful substance major part in the smog in the filtering bodies, a part is adsorbed by active carbon 4, thereby has protected smoker's health better.In addition, this practical filtering bodies also can be with the mixture that sandwiches active carbon in the absorbent cotton.

Claims (1)

1, a kind of cigarette filter, it is made up of filter-tipped packing paper (1) and filtering bodies (2), it is characterized in that filtering bodies (2) is by taking off the cotton layer of paper I (3), activated carbon layer (4), taking off the cotton layer of a paper II and form for (5) three layers.
