Abstract

The utility model relates to a filter-tip rod and is characterized in that a filter element rod (5) is packaged into the filter-tip rod by a forming paper (4), an embossment (2) with slots and an inter-package paper (1); a spiral walkway is formed by the truncation points between the slot and the embossment (2), thus the trends of partial cigarette smokes are changed, the mainstream cigarette smoke is thinned, the residence time of the lateral air steams in the filter-tip rod is prolonged, the Brownian movement of the cigarette smokes in the filter element become more intense, traversing filtration and fibre filter-paper filtration are added, filtration effect is improved, and the risk of harmful substances like tar on human health is reduced to the utmost extent.

Description

Section formula groove filter rod

Technical field

The utility model relates to tobacco business, particularly relates to a kind of filter stick of cigarette.

Background technology

At present generally adopt cigarette to prop up to install filter rod additional and alleviate the harm of smoking human body, but common filter rod just is made up of filter core rod and forming paper, flue gas is comparatively unobstructed by the process of filter tip, limited to harmful components filter effects such as tars, can not satisfy cigar mill to the requirement of cigarette products and consumers in general to smoking and healthy growing interest, therefore, change original filter rod structure, thereby further alleviate composition harmful in the flue gas, become inexorable trend.In order to change above-mentioned unfavorable situation, on the market a kind of straight-line groove filter rod has appearred recently, and it significantly improves the harmful components filter effect in the flue gas.But flue gas flows in groove still can be comparatively unobstructed, and it is shorter relatively that flue gas is detained the time of groove, and its strainability still remains further to be improved.

Summary of the invention

The purpose of this utility model is exactly that the structure of original straight-line groove filter rod is improved, to overcome the deficiency that exists in the prior art.

To achieve these goals, the utility model has adopted following technical proposals: groove filter rod described in the utility model, form by filter core rod, inner wrapping paper and forming paper thereof with groove embossing, it is characterized in that groove embossing on the inner wrapping paper is along the axial setting of filter core rod, disconnect between the two axially adjacent groove embossings and form section, the set of section and groove embossing and shaping paper form helical duct on the inner wrapping paper, the angle of inclination of control helical duct, finally making has 1-3 road helical duct on each mouth rod.And groove embossing on the described inner wrapping paper and filter core rod axially also can be provided with the inclination certain angle.Described inner wrapping paper is a tobacco business fiber filter paper (also can be other paper) commonly used, it enters opium pipe synchronously with forming paper after being pressed into the required groove embossing that has section by emboss, the filter core rod is rolled into filter rod, because the effect of plasticizer (triacetyl glycerine) is arranged in the filter core rod, make on the filter core rod produce with fiber filter paper on the corresponding groove of embossing, section, groove embossing and forming paper formation spiral low-pressure channel on the inner wrapping paper.

Advantage of the present utility model is: owing to there is the existence of section that flue gas stream is blocked, force the flue gas in the groove to enter helical duct by inner wrapping paper, increased the horizontal filtration of filter core rod and inner wrapping paper than prior art; The flue gas stream spiral that enters helical duct rises, and has changed the trend of flue gas, and after suction stops, because this passage is a low-pressure channel, have partial fume to reflux along this passage, therefore delayed the holdup time of flue gas at this passage, harmful components such as tar are filtered comparatively abundant in the flue gas; Because the existence of helical duct, resistance to suction does not increase, and sucks that taste is plentiful, outward appearance is novel, the advantage of reducing tar and reducing harm so have.

For more detailed description the utility model, following routine accompanying drawing provides two the bests of the present utility model

Embodiment:

Description of drawings:

Fig. 1 is a straight-line groove boss structure schematic diagram of the present utility model;

Fig. 2 is an oblique line groove boss structure schematic diagram of the present utility model;

The specific embodiment

As shown in Figure 1, inner wrapping paper 1 is wrapped up filter core rod 5 and inner wrapping paper 1 by forming paper 4 after tow filter core rod 5 is wrapped up again.Described inner wrapping paper 1 is provided with groove embossing 2, its horizontal end face equal difference is arranged continuously, be interrupted vertically and arrange, promptly between the two adjacent grooves embossings 2 whether section 3 is arranged, all section set form helical duct and (during use whole filter rod peace certain-length are blocked into the mouth rod and prop up the bonding Zhi Xiangyan that becomes to put in order with cigarette, make and comprise 1-3 road helical duct on each mouth rod), its cross-sectional view is shown in the right part of Fig. 1, therefrom flue gas stream flows to the high spot of section 3 from the groove space that forms between forming paper 4 and the groove embossing 2 as can be seen, be forced to pass inner wrapping paper 1 and enter the helical duct that forms between itself and the forming paper 4, to such an extent as to have aforesaid advantage.As shown in Figure 2 be groove embossing 2a on the inner wrapping paper and the setting of filter core rod axioversion, its filter effect is better.

Claims

1, a kind of section formula groove filter rod, it is made up of the forming paper of filter core rod, the inner wrapping paper with groove embossing and outer parcel thereof, it is characterized in that groove embossing on the inner wrapping paper is along the axial setting of filter core rod, disconnect between the two axial adjacent grooves embossings and form section, the set of section and groove embossing and shaping paper formation helical duct on the inner wrapping paper.

2, filter rod according to claim 1 is characterized in that groove embossing and filter core rod axioversion certain angle on the inner wrapping paper.
