Abstract

The utility model discloses a cigarette filter, which comprises a piece of packaging paper and a filter body, wherein the filter body is covered by the packaging paper, and the filter body is structurally divided into three layers, namely a cellulose acetate fiber layer, an activated carbon layer and a Lyocell fiber layer in sequence. By using the cigarette filter, a large amount of harmful substances in smoke remain in the cigarette filter so as to well protect the health of a smoker.

Description

Cigarette filter

Technical field

The utility model relates to a kind of cigarette filter.

Background technology

Filter tip is meant the top of cigarette, is used for a filtering part to suck the tar in the flue gas, reduces the sense of discomfort after smoker's smoking.Along with development of science and technology, very big variation has also taken place in the kind of filter tip itself.

Nineteen twenty-five, Boris A Weiasi has applied for making with crimped paper and cellulose wadding etc. the patent of cigarette filter at the Ortmann plant experiment of Zou of Britain nation paper industry.A Weiasi is from the subsidiary FILTRONIC co-production cigarette filter of nineteen twenty-seven with Zou of nation, but owing to lack the machinery of producing Filter cigarette, the market receptance is lower.　　

Nineteen thirty-five, a tame Britain company begins exploitation and adorns filter-tip machine to cigarette.By 1954, manufacturer introduced this machine more widely, and after this doctor and researchers have delivered a series of PUD Ds and smoking possibility relevant study, and filter tip begins to come into one's own.Because cigarette with filter tip is considered to " safety ", play them and occupied the market leading position sixties in 20th century.The used for filter tip stopper look of traditional cigarette with filter tip.Recently also some manufacturer adopts white cigarette holder.The cigarette holder of white also can be used for representing a kind of mint type cigarette of Britain and the light-duty cigarette of the U.S..

Although the cigarette filter by the crape silk paper is processed is introduced European cigarette market first in the twenties in 20th century,, up to the 1950's, along with the exploitation of acetate fiber, cigarette with filter tip just begins to obtain consumer's extensive approval.　　

Since the 1950's, cigarette with filter tip begins on most of market, the world, to show up prominently at large.Because the consumer has increased the interest of the less product of smog, the cigarette with filter tip market share of many countries has surpassed 90% to 95%.Contain more than 40 kind of carcinogen such as hundreds of kind harmful chemical composition, particularly tar, nitrosamine etc. in the smog that produces during cigarette combustion, this has been general knowledge common to all.

Include particulate in the cigarette smoke, be referred to as tar usually.Containing a large amount of chemical compositions in the tar, have 4000 to 5000 kinds, all is the unburnt product of tobacco.Except tar, also include other materials in the cigarette smoke, like " steam " or " gas " phase, also comprise volatile result of combustion of tobacco material, like acetaldehyde and other low molecular wt composition.Other phases in the cigarette smoke like " half volatile " phase, comprising many combustible substances, are equal to particulate and vapor phase.Cigarette filter can filter the smog composition.

Summary of the invention

The utility model technical problem to be solved provides a kind of cigarette filter.

For solving the problems of the technologies described above the technical problem of the utility model, realize through following technical scheme:

A kind of cigarette filter is made up of wrapping paper and filtering bodies, and said wrapping paper is coated on the said filtering bodies, and said filtering bodies is a three-decker, is followed successively by acetate fiber layer, active carbon layer and Lyocell fibrage.

Active carbon can effectively filter the tar in the flue gas; The Lyocell fiber is arranged on the filter tip; Need not just can reach the level of low tar and low Nicotine volatilization by means of the ventilation link of high level easily, therefore, it reduces the volatilization of carbon monoxide in the cigarette.

With respect to prior art, the characteristics of the utility model are following:

The cigarette filter of the utility model can make the most of harmful substance in the smog remain in the filter tip, thereby has protected smoker's health better.

Description of drawings

Fig. 1 is the utility model cigarette filter structural representation.

The specific embodiment

Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.

As shown in Figure 1, to form by wrapping paper 1 and filtering bodies 2, said wrapping paper 1 is coated on the said filtering bodies 2, and said filtering bodies 2 is a three-decker, is followed successively by acetate fiber layer 21, active carbon layer 22 and Lyocell fibrage 23.

Lyocell fibrage 23 links to each other with cigarette cut tobacco layer 3.

The above; Be merely the specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the utility model disclosed, and variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.

Claims

1. a cigarette filter is made up of wrapping paper and filtering bodies, and said wrapping paper is coated on the said filtering bodies, it is characterized in that: said filtering bodies is a three-decker, is followed successively by acetate fiber layer, active carbon layer and Lyocell fibrage.
