Abstract

The utility model relates to a radiation-proof cigarette filter tip for reducing smoking harm to a human body, which comprises a filter tip, the inner part of which is filled with filtering fiber. The surface of the filtering fiber has a metal coating which can be a silver coating or a copper coating or an iron coating or an aluminum coating or a chromium coating. The utility model can filter the harmful substances, such as nicotine, smoke tar, etc., and can shield alpha rays, which reduces the harm to the human body.

Description

Radiation-proof cigarette filter tip

The utility model relates to a kind of be used to the reduce cigarette filter tip of smoking to human body harm, particularly a kind of radiation-resistant cigarette filter tip.

As everyone knows, cigarette is contained the material that kinds more than 20 such as nicotine, tar are harmful to human body.But report is pointed out according to the study, and the real arch-criminal that cigarette causes the people to suffer from lung cancer is radioactive substance---the alpha ray that smoke point combustion back is discharged.According to surveying and determination, every day a deck the people, his bronchus will be subjected to the Alpha-ray radiation of 5000-5500 mrem every year, is equivalent to carry out the amount that 250 X ray fluoroscopies of chest are accepted.The permission amount of radiation that ICRP proposes is annual 500 mrems, is its 10 times strong and take out the amount of radiation that the people of a deck stands every year every day, and the alpha ray of visible smoke is serious to human body harm.Though it is cigarette filter tip of the prior art has filtration to harmful substances such as nicotine, tars, powerless to the alpha ray of cigarette.

The purpose of this utility model is to provide a kind of radiation-resistant cigarette filter tip, not only harmful substances such as nicotine, tar is had filtration, and can the alpha ray of cigarette be shielded, and reduces its harm to human body.

For achieving the above object, the utility model adopts following technical proposals: this radiation proof cigarette filter tip is the same with prior art, includes the filter tip of a solid filter fiber.There is the coat of metal on the surface that is characterized in filter fiber.This coat of metal can play shielding action to alpha ray in the cigarette.To reduce its harm to human body.

The above-mentioned coat of metal can be silver, copper, iron, aluminium or chrome plating.Filter fiber can be natural fiber or synthetic fibers.The technology of fiber surface plating can adopt known plated film technology, operation such as its technical process comprises that fiber deoils, surface roughening, sensitization, activation and plated film.

The utility model has significant advantage compared with prior art: this radiation proof cigarette filter tip not only has filtration to harmful substances such as nicotine, tars, and can shield alpha ray, does not make ray enter human body; The filter fiber material that uses does not need to ask too high, reduces cost; Metallising process is simple; The filter tip outward appearance of making is well-pressed.

Fig. 1 is the structural representation of an embodiment of the utility model.

Fig. 2 is the structure enlarged diagram of plating filter fiber.

A most preferred embodiment of the present utility model is: referring to Fig. 1 and Fig. 2, fill up filter fiber 2 in the filter tip 1 of cigarette, there is the coat of metal 3 on the surface of filter fiber 2.This coat of metal 3 is silvering.

Claims

1, a kind of radiation proof cigarette filter tip that is used to reduce smoking to human body harm comprises the filter tip (1) of a solid filter fiber (2) it is characterized in that there is the coat of metal (3) on the surface of filter fiber (2).

2, radiation proof cigarette filter tip according to claim 1 is characterized in that the coat of metal (3) is silver, copper, iron, aluminium or chrome plating.
