Abstract

A cigarette filter with high efficient filtration of tar does not change the taste of the cigarette, which can filter off a plurality of folds of the tar without wasting labor sense of suction. Every box of cigarettes just needs to increase a cost of a plurality of fen. The cigarette filter comprises filtering silk floss, which is characterized in that a filter sheet is added between (1) or before (2) the filter tip.

Description

New-type cigarette with high-efficient filter-tip

A kind of filter-tip of efficient filter tar belongs to daily class.

Present cigarette filter has filtered out part tar, has to a certain degree improved the harm to health of smokers, but most of tar does not filter out yet.If too much extend filter tip, obviously unactual yet, must effectively study improvement to strobe utility.The technology that addresses this problem at present, except that the filter tip of common lengthening, some advanced country has adopted the filter tip that adds activated carbon, uses active carbon adsorption tar, increases the tar content that leaches; The state-of-the-art technology that Japan Gray tobacco company releases adds safflower oil, to leach more tar in filter tip.But this technical costs height, the cigarette price is high-spirited expensive, is difficult in China's cigarette production industry to use.

The purpose of this utility model is the more effectively interior tar of filter cigarette, thereby improves the harm to the smoker greatly.

By research, the inventor finds to add the thin slice around the hole is around the center of circle, filtered tar extremely effectively in the middle of filter tip.This is because of present filter tip, and along with sucking of people, by filter hair floss, radial motion is very little along axially for cigarette, and therefore the tar that filters in finite length is limited.And having added the filtration thin slice, cigarette will pass through aperture all around, has increased the power of cigarette radial motion greatly, under same length, has increased the ability that filters out tar greatly.Experiment showed, this increased filter disc filter tip, people's smoking there is no the sense of effort.

Load onto after this filter and filter hair floss together, the tar that filters out is multiplied, and opens that cigarette filter is first sees that comparative effectiveness is fairly obvious.Cost increases every cigarette and is no more than red cent.

Accompanying drawing 1 is the cigarette with filter tip structural representation that adds filter.

Accompanying drawing 2 is filter structural representations.

Accompanying drawing 3 is the operable filters of special cigarettes.

Accompanying drawing 4 is cigarette structure schematic diagrames of high efficiency filter tip.

Accompanying drawing 5 is cigarette structure schematic diagrames of examining the shape fairing in filter tip with jujube.

Several effective embodiment of following discloses:

Embodiment 1, as accompanying drawing 2, a plurality of holes around the center of circle arranged on the filter, and the gross area of aperture is no more than 1/5th of whole filter area, greater than its 1/10th (otherwise the smoking meeting is painstaking).Generally can take five pore structures, also can adopt other hole count, as four holes, six holes or the like.

Embodiment 2, to heavy cigarettes such as mixed type or cigar, can add the filter as accompanying drawing 3, and the gross area of aperture is no more than 1/3rd of whole filter, greater than its 1/8th.Accompanying drawing 3 is a kind of arranging.Also can take other form, but double-deck concentric circle holes is better.

Embodiment 3, as accompanying drawing 1, can be added in (position as 1) between the filter tip to filter; Also can be added in and near the position 2 of cigarette end as accompanying drawing 4; Also can all add such filter in 1 and 2 position, filter effect is better, and it is painstaking that smoking also can't be felt.

Embodiment 4, as accompanying drawing 5, add a jujube nuclear shape fairing 3 in filter tip, and effectively filtered tar does not have any difference sense during smoking.

Claims

1, a kind of cigarette filter is made up of filter hair floss, it is characterized in that between filter tip (1) or before (2) add a filter.

2, according to claim 1 and cigarette filter, it is characterized in that having on the filter a plurality of holes of arranging around the center of circle.

3, cigarette filter as claimed in claim 1 is characterized in that can have around circle center hole on the filter arranged more.

4, cigarette filter according to claim 1 is characterized in that filter can be placed in (1) and front (2) between the filter tip simultaneously.

5, cigarette filter as claimed in claim is characterized in that adding the fairing (3) that a jujube is examined shape between filter tip.
