Abstract
The utility model discloses a filter tip for a cigarette, which solves the problem that the present filter tip for a cigarette has nonideal filter effect. The utility model comprises an activated carbon chamber which is filled with activated carbon, wherein, the top surface of the activated carbon chamber and the bottom surface of the activated carbon chamber are respectively provided with micropores through which smoke gas can pass; the top of the activated carbon chamber and the bottom of the activated carbon chamber are respectively sheathed with a sleeve barrel and a cigarette tip; the bottom of the sleeve barrel, which is connected with a cigarette rod, is provided with a micropore through which the smoke gas can pass; a hollow cavity is prearranged between the bottom of the sleeve barrel and the top of the activated carbon chamber, and the hollow cavity is a filter chamber for tar for the first time; an inner cavity of the cigarette tip is a filter chamber for tar for the second time. The utility model has the advantages of good filter effect, economy, and application.
Description
The utility model relates to a kind of cigarette filter.
Smoking is harmful, but for the people who is addicted to smoking, does not accomplish non-smoking again.Harmful substance has played very big effect to cigarette filter in the suction body to reducing.The filter tip that uses on cigarette at present all is a fiber product, and not thorough to the filtration of harmful substance, filter effect is not very good, and fiber product itself also has certain side effect to human body.
The purpose of this utility model provides a kind of good filtration effect, the cigarette filter that human body is had no side effect.
For achieving the above object, the utility model is taked following design: a kind of cigarette filter, comprise that one is full of the activated carbon chamber of active carbon, and the end face of described activated carbon chamber and bottom surface are respectively equipped with the micropore that can supply flue gas to pass through; The top of described activated carbon chamber and bottom are arranged with sleeve and cigarette holder respectively; The bottom that described sleeve is connected with tobacco rod is provided with the micropore that passes through for flue gas, leaves a cavity between the top of this bottom and described activated carbon chamber, is a tar filter chamber; The inner chamber of described cigarette holder is secondary tar filter chamber.
The utility model has the advantages that: filtering out harmful matter is thorough, and is in light weight, cost is low.
When flue gas by smoker's smoking action suction when the filter tip direction flows, a part of tar particle collision is to the bottom of sleeve, and is attached at this place.After flue gas entered tar filter chamber, the tar particulate was accelerated, and a part impinges upon on the top board of activated carbon chamber, and piled up, and stayed in the tar filter chamber.Remaining tar particulate enters the activated carbon chamber with flue gas, and in the activated carbon chamber, most tar particulates are adsorbed by activated carbon.After flue gas entered secondary tar filter chamber, owing to cigarette holder is flat and is gradually thin shape, flue gas slowed down at this, and the tar particulate that has also can stick on the cigarette holder wall.Like this, the tar particulate in the flue gas is equivalent to pass through filter four times, can thoroughly be disposed basically.
Cigarette holder part of the present utility model can be one time punching molded with aluminium alloy, be placed in the mouth can not have side effects to human body, and active carbon also is harmless to human body.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the A-A cutaway view of Fig. 1
As shown in Figure 1 and Figure 2, the utility model by the activated carbon chamber 1 that is full of active carbon, be set in the top of activated carbon chamber 1 and the sleeve 2 and the cigarette holder 3 of bottom respectively and form.Activated carbon chamber 1 is cylindrical, and its top and bottom are provided with several micropores 11 that can supply flue gas to pass through; The bottom of sleeve 2 and tobacco rod 6 join, and which is provided with several for the micropore 21 that flue gas passes through, and leave a cavity 5 between sleeve 2 bottoms and the activated carbon chamber 1, are a tar filter chamber, and corresponding site is provided with groove 22 on the wall of sleeve 2, uses fixedly activated carbon chamber 1; The end of cigarette holder 3 is flat type, and is the gradually closing shape, is sheathed on the bottom of activated carbon chamber 1, and the inner chamber of cigarette holder 3 is secondary tar filter chamber.
In the above-described embodiments, sleeve 2 and cigarette holder 3 can join, and become one.
The utility model activated carbon chamber 1 can be multiple shape, can be cylindrical, polygon prism, cuboid etc., and the shape of cigarette holder 3 also is various, can be circle, flat, triangle etc.
