Abstract

The utility model relates to a cigarette filter tip with a composite structure. The utility model is composed of a filter body which is composed of two sections of high molecular fibres, and a separation membrane which can block smoke particles which are released when a cigarette is burnt. The utility model can effectively prevent dust and nicotine toxin from entering the body of a smoker. The separation membrane is provided with micropores which are evenly distributed for guaranteeng that the filter tip has enough ventilation performance. The novel filter tip which can be arranged on the tail of each cigarette and can be arranged in a permanent type cigarette mouth has the advantage of low cost.

Description

The composite construction cigarette filter tip

The present invention is a kind of New-type cigarette filter tip.

The harm of smoking health, known by everybody.Yet because each side still has a lot of people to smoke.So people adopt various measures, alleviate the harm that smoking causes human body as possible.At the afterbody of every cigarette, enclose a bit of filter tip of making by macromolecular fibre, be one of existing method.In fact, this method is far longer than its practical function to the psychological placebo effect of smoking people.Because the pore size of existing cigarette filter tip is big, and skewness, the smoke particle of emitting in the time of can not stopping result of combustion of tobacco fully, thereby can not stop the nicotine toxin in the tobacco to enter human body.

The purpose of this invention is to seek a kind of novel cigarette filter tip, makes the psychological application that can satisfy the smoking people, can stop conscientiously that again the smoke particle that result of combustion of tobacco is emitted enters human body, thereby reaches the purpose of the suction nicotine toxin of realizing minimum limit.Realize that key of the present invention is the overanxious microstructure design of chewing of cigarette.Traditional filter tip is made by macromolecular fibre of the same race, and density too conference influences gas permeability, and the too little then space of density is too big, can not play a role in filtering.The present invention (Fig. 1) adopts a kind of composite structural design, advances a kind of diffusion barrier in the filtering bodies therebetween that two sections macromolecular fibres are made, and makes a kind of New-type cigarette filter tip.It is characterized in that filtering bodies and one deck diffusion barrier that it is made up of two sections macromolecular fibres are composited.The axis of diffusion barrier is identical with filter tip exterior cylindrical body axis.Curved surface is H at the height of axis direction, H=0～13mm.When H=0, diffusion barrier is the plane perpendicular to axis.Be covered with micropore on diffusion barrier equably, the micropore average-size is 1～90 μ m.Diffusion barrier is support with the macromolecular fibre filtering bodies section of rear side, to guarantee smoking time-division of exerting oneself from membrane micropore excessive distortion not taking place the smoking people.The composite construction that the macromolecular fibre filtering bodies of diffusion barrier and its both sides constitutes is fixed by the cylindric fine matter shell that sticks at the filter tip periphery, becomes one.

The present invention has following advantage:

(1) smoke particle that produces in the time of can stopping most cigarette combustion enters human body, thereby makes the smoker avoid the harm of nicotine toxin;

(2) cost is low: owing to inserting of diffusion barrier, every cigarette increases only 3～5 fens of cost, easily is that numerous smokers accept;

(3) this filtering bodies has versatility.Can be placed on the afterbody (having cigarette producers to finish) of every cigarette, also can be placed on the various permanent cigarette chew among (by smoker oneself operation), easy to use.

Fig. 1 is the fragrant filter tip schematic diagram of composite construction.Wherein: 1-macromolecular fibre porous body, 2-diffusion barrier, 3-paper shell.

Fig. 2 puts into the schematic diagram of permanent type filter tip for the composite construction cigarette filter tip, wherein:

The permanent filter tip of 4-.

Fig. 3 is the shape schematic diagram of diffusion barrier in the composite construction cigarette filter tip, and H is the height of surface of revolution among the figure, and T is the thickness of diffusion barrier.When H was 0, curved surface became a plane.When the H value increased, the filter area of diffusion barrier increased,, air communication is crossed resistance and is reduced.But the root a tree name need be regulated gas-flow resistance by the size that changes the H value during design.

Embodiments of the invention:

Composite construction cigarette filter tip as shown in Figure 1, wherein diffusion barrier is the varicosity polytetrafluoroethylene film, the film micropore average-size is 0.8mm, thickness is 0.06mm, the plane curve (Fig. 3) that the bus of diffusion barrier surface of revolution was made up of level and smooth connection of two sections quarter turn lines, apart from front end 15mm, apart from rear end 5mm.The two sections porous bodies in front and back are the polypropylene short fiber formation of 0.02mm by diameter, and its density is identical with existing cigarette filter tip.The outer bonding of filter tip of the present invention one deck papery cylindrical shell plays fixation (Fig. 2) to composite construction.The external diameter of papery cylindrical shell is 8mm.
