Abstract

The utility model relates to a cigarette filter tip rod, and is characterized in that the filter tip rod is formed by that a filter core rod 3 covered by forming paper 1 and fiber filtering paper 2 provided with a twill groove embossing or a cross groove embossing. The utility model comprises an unidirectional spiral twill groove or a bidirectional cross spiral groove, and dilutes mainstream smoke, changes direction of the partial smoke, delays the retention time of a lateral air flow in the filter tip rod, dramatically accelerates Brownian motion of smoke in the filter core, increases the horizontal filtering and the filtering of the fiber filtering paper, improves the filtering effect, and reduces the harm of the human body caused by the harmful substances of tar etc. to a great extent.

Description

Twill groove filter rod

Technical field

The utility model relates to tobacco business, particularly relates to a kind of filter tip 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 the forming paper of filter core rod and outer parcel, flue gas is comparatively unobstructed by the process of filter tip, limited to harmful components filter effects such as tars, for the smoking demand that satisfies people and to the requirement of health, must change original filter structures and reduce harmful ingredients in flue gas and reduction tar content better to reach.

Summary of the invention

The purpose of this utility model is exactly the filter rod of a kind of brand new of proposition, to overcome the deficiency that exists in the prior art.

To achieve these goals, the utility model has adopted following technical proposals: based on common filter rod, it comprises filter core rod and outer forming paper thereof, it is characterized in that having between forming paper and the filter core rod one deck to have the integument of vertical corrugated embossing, make on filter core rod and the forming paper and form vertical corrugated embossing groove.In order to bring into play the effect of groove more fully, the corrugation groove of integument can be formed twill groove embossing to lopsidedness; Or the corrugation groove of integument is formed slopely intersection twill groove embossing to two rightabouts.They engage the back and form spiral twill groove or cross-helicity twill groove along filter core rod cylinder with the filter core rod.This integument is a tobacco business fiber filter paper commonly used, it enters opium pipe synchronously with forming paper after being pressed into required corrugation embossing 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 produce on the filter core rod with fiber filter paper on the corresponding groove of embossing.

Advantage of the present utility model is: cigarette props up by suction, air-flow flows in the twill groove primary air is divided into vertically, horizontal bidirectional-movement, reduced the primary air exhaust gas volumn, strengthened the lateral flow of air-flow, that is the passage that the annular ditch groove by spiral produces low step-down has diluted main flume, improved the filter segment ventilation rate, changed the partial fume trend, delayed the holdup time of lateral airflow at filter rod, make the Brownian movement of flue gas in filter core more violent, increased horizontal filtration and fiber filter paper and filtered, thereby improved filter effect, reduced the burst size of harmful substances such as tar to greatest extent and the harm of human body.In addition, the utility model also has the novel appearance different with common filter rod, also has antifalse effect to a certain degree.

For more detailed description the utility model, following routine accompanying drawing provides one group of the best of the present utility model

Embodiment:

Description of drawings:

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

Fig. 2 is the three-dimensional schematic diagram that launches of twill groove filter rod of the present utility model;

Fig. 3 is the three-dimensional schematic diagram that launches of intersection twill groove filter rod of the present utility model;

Specific embodiment

As shown in Figure 1, the integument 2 (fiber filter paper) that has corrugation groove embossing wraps up filter core rod 4 jointly together with forming paper 1, because the effect of corrugation groove embossing, make groove 5 is arranged between filter core rod and the forming paper, owing to the effect of plasticizer (triacetyl glycerine) is arranged in the filter core rod, makes and produce corresponding projection 3 on the filter core rod.The structure of the twill groove filter rod that Fig. 2 shows, forming paper 1 and integument 2 are opened a part simultaneously, can see also have on the filter core rod 3 with integument 2 on corresponding twill groove A.The structure of the intersection twill groove filter rod that Fig. 3 shows, forming paper 1 is opened a part, and can see on filter core rod 3 and the integument 2 has corresponding intersection twill groove B.

Claims

1, a kind of twill groove filter rod, it comprises filter core rod and outer forming paper thereof, it is characterized in that having between forming paper and the filter core rod integument of one deck corrugated embossing, makes on filter core rod and the forming paper and forms vertical corrugated embossing groove.

2, filter rod according to claim 1, the corrugated groove embossing that it is characterized in that integument is a twill groove embossing, and forms spiral twill groove along filter core rod cylinder.

3, filter rod according to claim 1 is characterized in that the intersection twill groove embossing of corrugated groove embossing for tilting to two rightabouts of integument, and forms spiral intersection twill groove on filter core rod cylinder.
