Description

A kind of double filtration cigarette holder

Technical field

The utility model relates to a kind of cigarette holder, especially a kind of double filtration cigarette holder.

Background technology

Filter-tip in the market, be in cigarette holder, arrange can change flue stream to filtration cigarette core or at inner some mediums of placing of cigarette holder, the structure structure of the former cigarette holder is comparatively complicated, makes cumbersome, and the production cost height, cause selling price expensive partially; Though the structure of latter's cigarette holder is comparatively simple, but the filter effect of medium is bad, because cigarette flows very fast at the inner chamber of cigarette holder, therefore medium can not adsorb the harmful substance in the cigarette at once, though can filter harmful substances such as part tar, reduce the concentration of harmful substance, but filter effect is not good.And the surface coverage harmful substance of medium, the obvious like this filter effect that reduces medium.

The utility model content

The utility model will solve the shortcoming of above-mentioned prior art, and a kind of double filtration cigarette holder is provided, and structural design is simple, is convenient to assembling, and production cost is low.

The utility model solves the technical scheme that its technical problem adopts: this double filtration cigarette holder, comprise cigarette holder cover and filter core, filter core is installed in the passage of cigarette holder cover, filter core comprises poly-smoke-box, the upper and lower side of filter core is respectively equipped with and protrudes the limit, protrudes the limit down, last protrusion limit, protrude between the inwall that limit, poly-smoke-box outer wall and cigarette holder overlaps and form smoke chamber down, have the horizontal venthole that leads to smoke chamber on the outer wall of poly-smoke-box, the cigarette holder cover inwall that wherein is positioned at the filter core below is provided with the tar oil drain tank, wherein protrudes on the limit down to have the vertical venthole that leads to the tar oil drain tank.

Wherein laterally venthole and the vertical position of venthole on filter core are interspersed.

Wherein cigarette holder puts and is provided with air louver.

The effect that the utility model is useful is: the utility model reasonable in design, the tar in the cigarette is carried out double filtration, and good filtration effect, and also this structure assembling is simple and convenient, the production efficiency height, and cost is low, is conducive to extensive popularization.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

With reference to accompanying drawing: this double filtration cigarette holder, comprise cigarette holder cover 1 and filter core 2, filter core 2 is installed in the passage of cigarette holder cover 1, filter core 2 comprises poly-smoke-box 2-3, the upper and lower side of filter core 2 is respectively equipped with and protrudes limit 2-1, under protrude limit 2-2, last protrusion limit 2-1, under protrude limit 2-2, form smoke chamber 4 between the inwall of poly-smoke-box 2-3 outer wall and cigarette holder cover 1, have the horizontal venthole 3 that leads to smoke chamber 4 on the outer wall of poly-smoke-box 2-3, the cigarette holder that wherein is positioned at filter core 2 belows overlaps 1 inwall and is provided with tar oil drain tank 6, wherein protrudes on the 2-2 of limit down to have the vertical venthole 5 that leads to tar oil drain tank 6.Wherein laterally venthole 3 and the vertical position of venthole 5 on filter core 2 are interspersed.Wherein cigarette holder cover 1 is provided with air louver 1-1.

The utility model reasonable in design is carried out double filtration, good filtration effect to the tar in the cigarette.Cigarette in the cigarette accumulates in the smoke-box 2-3 after sucking, cigarette passes through from horizontal venthole 3 earlier, because laterally the aperture of venthole 3 is less, make the tar high velocity impact in the cigarette remain in smoke chamber 4 in inwall and the part of cigarette holder cover 1, like this tar has been carried out once filtering, cigarette after the filtration flows out at a high speed from vertical venthole 5, identical with the principle of horizontal venthole 3, the tar that flows out at a high speed from vertical venthole 5 collides and remains in the tar oil drain tank 6, thereby through filtering for the second time, filter more thorough to tar in the cigarette like this.

Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
