Description

Cigaratte filter

Technical field

The utility model relates to a kind of cigarette filter constructions, and it makes cigaratte filter have oil trap, oil-collecting space, accumulates nicotine thereby obtain big oil-collecting space, and has the effect of better tar filtering.

Background technology

Existing cigarette filter constructions substantially as shown in Figure 1, comprises a tubular body 10, is provided with stopper 12 in the body 10, and stopper 12 makes the through hole of body 10 reduce the aperture, and stopper 12 front ends also are provided with protuberance 13, and protuberance 13 is provided with passage 14 allows cigarette pass through.Its operation principle is: the tobacco tar that produces because of smoking can be blocked the passage 14 that passes through protuberance 13 that piece 12 stops, tobacco tar infiltrates wall 16 to be subjected to stopping the collision back with oblique oil-collecting face 17 and to flow into oil-collecting space 15, thereby produces the effect of tackling nicotine, tar.Said structure has following shortcoming:

(1) tobacco tar can't be done multiple filtration, and the oil-collecting space only is formed on the ring-type wall, and the space is also less, and nicotine, tar adhere to limited.

(2) it has only simple stopper 12, does not have other filter, so still have more nicotine, tar is inhaled into human body.

(3) when the filter of nicotine, tar is long-pending a certain amount of, allows the user be drawn onto previous filtering easily and accumulate nicotine, tar in the filter tip pipe.

The utility model content

Technical problem to be solved in the utility model is: in existing cigarette filter constructions, tobacco tar can't be done multiple filtration, the space is less, nicotine, tar adhere to limited, when the filter of nicotine, tar is long-pending a certain amount of, allows the user be drawn onto previous filtering easily and accumulate nicotine, tar in the filter tip pipe.

The utility model provides a kind of cigaratte filter, and it is made of body, chimney filter, the combined integrated institute of smoke pipe; It is characterized in that,

Described body is designed to have the hollow form of through hole;

Described chimney filter is designed to, and the below has for plugging together socket part in body, in be provided with stopper, this stopper bottom is provided with oil trap, oil-collecting space and is provided with through hole;

Described smoke pipe has through hole, and the lower end plugs together in chimney filter, and cigarette is inserted in the upper end.

Based on said structure, the utility model can be achieved as follows beneficial technical effects:

One, be provided with stopper, oil trap, oil-collecting space, through hole in the chimney filter, and obtain to form multilayer, multiple tracks filtration nicotine, tar effect, and big oil-collecting space is arranged, and increase the tobacco tar impact area, thereby have nicotine, the tar effect that to concentrate more amount.

Its two, the below is provided with filter element in the chimney filter, can strengthen the effect of filtering nicotine, tar once more, prevents user's be drawn onto the oil-collecting space nicotine of hoarding, taste of tar.

The specific embodiment

See also Fig. 2, Fig. 3, cigaratte filter of the present utility model is made up of body 20, chimney filter 30, smoke pipe 22; Wherein, body 20 is hollow form, has through hole 21; Chimney filter 30, below have socket part 35 for plugging together in body 20, are provided with stopper 31 in it, and stopper 31 bottoms are provided with oil trap 32, reach the oil-collecting space 33 that communicates with oil trap 32, and are provided with through hole 34; In addition, stopper 31 surface design become matsurface 310, are provided with filter element in the socket part 35 of chimney filter 30; Smoke pipe 22 has through hole 23, and its lower end plugs together in chimney filter 30, upper end for inserting cigarette.

Based on above-mentioned structure, now operation principle of the present utility model is described in detail as follows: as shown in Figure 3, when cigarette is sucked into into chimney filter 30, at first can be blocked piece 31 and stops, form the effect of interception nicotine, tar.When cigarette then arrives oil trap 32, oil-collecting space 33, can be blocked once more and tackle nicotine, tar, but nicotine, tar productive set are in oil trap 32, oil-collecting space 33, flue gas is via through holes 34 and filter element 36 by the below again, can be tackled nicotine tar residual in the flue gas once more, this filter element 36 can adopt " activated carbon, cotton " to make, and forms imperceptible filter effect.Therefore, the utility model has following effect, advantage as can be known:

(1) is provided with stopper 31, oil trap 32, oil-collecting space 33, filter element 36, forms the effect of multilayer, multiple tracks interception nicotine, tar.

(2) stopper 31 surface design become matsurface 310, the flowing velocity of cigarette is slowed down and have the effect of auxiliary interception nicotine, tar.

(3) but nicotine, tar productive set in oil trap 32, umbrella shape oil-collecting space 33, and obtain bigger oil-collecting effect, be difficult for taking place to block the problem of through hole 34, thereby keep preferable ventilatory effect.

(4) be provided with the big umbrella shape space in oil trap 32, oil-collecting space 33, can increase nicotine, tar accumulated amount, and can prevent that tar from flowing into filter element 36, clogged conditions takes place and influence the effect that filter element 36 filters, and can increase access times, reach the purpose of economy, environmental protection.
