Abstract

The utility model relates to a core for filtering tar in cigarette holders. The core comprises a cylindrical tar accumulating chamber; a smoke guiding hole is formed on the side wall of the tar accumulating chamber; a pulling rod is slidably inserted in the tar accumulating chamber; a tar scraper ring is fixed on the outer side at the front end of the pulling rod, and is in slidable friction with the inner side wall of the tar accumulating chamber; a tar accumulating flue is formed between the middle section of the pulling rod and the inner side wall of the tar accumulating chamber; the inner side of the front end of the pulling rod adopts a suction flue which is communicated with the tar accumulating flue through a high-pressure jet smoke hole in the side wall of the suction flue; a sealing ring is arranged at the front end of the tar accumulating chamber; and the rear end of the pulling rod extends out of the tar accumulating chamber, and is in threaded connection with a rivet nut. The utility model overcomes the defects of short service life and great waste of raw materials of the ordinary filtering core in the prior art. Through the design in the utility model, when tar is accumulated on the inner layer of the tar accumulating chamber, the tar on the inner side of the tar accumulating chamber can be squeezed out from the smoke guiding hole by the tar scraper ring on the pulling rod, so that the filtering core can be reused. Besides, the core for filtering tar in cigarette holders has the advantages of simple and compact structure, good filtering effect and long service life.

Description

Cigarette holder tar filters the cigarette core

Technical field

The utility model relates to a kind of cigarette holder tar and filters the cigarette core.

Background technology

Harm of smoking is healthy to be the reason of everybody knows, and along with progress and the relevant the construction of legal rules of country's reinforcement of society, smoking cessation has become main flow.Owing to well-known reason, the difficulty of smoking cessation is very big equally, and the method for harmful substance reduces the harm of smoking to human body as much as possible in quantity that general smoker often can only be by reducing smoking consciously or the filtering smog.Existing a kind of filter-tip, be in cigarette holder, be provided with can change flue stream to filtration cigarette core, though can filter harmful substance such as part tar, reduce concentration, but it is just long-pending in focus cell after inhaling several cigarettes has expired tar and has scrapped, and almost is disposable use, and service life is extremely short.Be not difficult to find, under the intact situation of cigarette holder body, only cause filtering cigarette core integral body and scrap and to cause raw-material significant wastage because the tar that filters piles up.

Summary of the invention

In order to overcome the problem that common filtration cigarette core in prior art service life is short, waste of raw materials is big, the utility model provides a kind of cigarette holder tar to filter the cigarette core, this cigarette holder tar filter the cigarette core simple and compact for structure, can remove the back to the tar in the focus cell and reuse, greatly improve service life.

The technical scheme that its technical problem that solves the utility model adopts is: comprise focus cell cylindraceous, the sidewall of focus cell is provided with exhaust hole, sliding plug is provided with pull bar in focus cell, the front end outside of pull bar is scraper ring fixedly, the madial wall of scraper ring and focus cell forms sliding friction, form the focusing flue between the stage casing of pull bar and the madial wall of focus cell, the front end of pull bar is inboard for sucking flue, sucks flue and is connected with the focusing flue by the high-pressure spray cigarette hole on its sidewall.

Front end in focus cell is provided with sealing ring.

Stretch out outside the focus cell rear end of pull bar, and be threaded and draw cap.

The utility model is by above-mentioned specific design, when in the focus cell during lamination tar, scraper ring on the pull bar can be extruded the tar on the focus cell madial wall from exhaust hole, make that to filter the cigarette core reusable, has the advantage of simple and compact for structure, good filtration effect, long service life.

Description of drawings

Below in conjunction with drawings and Examples detailed content of the present utility model is described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation that the utility model is removed the tar state;

Fig. 3 is a decomposition texture schematic diagram of the present utility model;

Fig. 4 is pack into a structural representation in the cigarette holder of the utility model;

The specific embodiment

As shown in the figure, the utility model comprises focus cell 1 cylindraceous, the sidewall of focus cell 1 is provided with exhaust hole 2, sliding plug is provided with pull bar 3 in focus cell 1, the front end outside of pull bar 3 is scraper ring 4 fixedly, scraper ring 4 can be made by elastomeric material, and scraper ring 4 forms sliding friction with the madial wall of focus cell 1.Form between the madial wall of the stage casing of pull bar 3 and focus cell 1 and focus on flue 5, focus on flue 5 and be communicated with cigarette holder flue 10 by exhaust hole 2.The front end of pull bar 3 is inboard for sucking flue 6, sucks flue 6 and is connected with focusing flue 5 by the high-pressure spray cigarette hole 7 on its sidewall.Front end in focus cell 1 is provided with sealing ring 8.Stretch out outside the focus cell 1 rear end of pull bar 3, and be threaded and draw cap 9.With the utility model cigarette holder of packing into, form high-seal between the sealing ring 8 of focus cell 1 front end and the cigarette holder inwall, under user mode, the smog that sucks is earlier through sucking flue 6, enter through high-pressure spray cigarette hole 7 again and focus on flue 5, and harmful substances such as tar are sprayed accumulate on the madial wall of focus cell 1, when the tar lamination arrives certain amount, can take out and filter the cigarette core, and by drawing cap 9 pulling pull bars 3, scraper ring 4 on the pull bar 3 can be extruded the tar on focus cell 1 madial wall from exhaust hole 2, make filtration cigarette core reusable.
