Abstract

The utility model relates to a cigarette filter rod characterized in that a filter rod with anamorphosis groove emboss is formed by a filting core rod3 which is wrapped by a shaped paper3 and a fiber filter paper1 with anamorphosis groove emboss. Due to the fact that the utility model is provided with a vertical groove or an obliquely twill rib weave groove, thereby diluting the main flow of smoke, changing the shifting direction of partial smoke, delaying the detention time of the lateral air flow in the filter rod, making the Brownian motion more vigorous when the smoke is in the filting core, increasing the traversingly filting and the filting of the fiber filter paper, improving the filter effect, maximally reducing the danger caused by the tar oil or other harmful substances to the human body.

Description

Gradual change 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 between forming paper and the filter core rod one deck integument being arranged, integument is provided with along the groove embossing of the axial gradual change of filter core rod, makes the groove embossing that forms vertical gradual change between integument and forming paper.The gradual change groove embossing of described integument also can be designed as twill groove embossing, forms spiral gradient twill groove along filter core rod cylinder.This integument is tobacco business fiber filter paper or a plain paper commonly used, it enters opium pipe synchronously with forming paper after being pressed into required groove 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, flue gas flows in the twill groove main flume is divided into vertically, horizontal bidirectional-movement, reduced mainstream smoke yield, 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, filter core rod laterally filtration and fiber filter paper filtration have been increased, thereby improved filter effect, reduced the burst size of harmful substances such as tar to greatest extent and, fallen burnt effect about 4mg the harm of human body.In addition, the utlity model has the novel appearance different, have the characteristics of special-shaped filter rod, also have antifalse effect to a certain degree with common filter rod.

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 an overall schematic of the present utility model;

Fig. 2 is the C partial enlarged drawing of Fig. 1;

Fig. 3 is the A-A cutaway view of Fig. 1;

Fig. 4 is a structure chart that the mouth rod is hinged with into a complete cigarette.

Specific embodiment

As shown in Figure 1, the integument 1 (fiber filter paper) that has gradual change groove embossing wraps up the filter core rod jointly together with forming paper 3, and filter rod comprises six sections mouth rod T, cuts off from transversal during use.Shape such as the Fig. 2, shown in Figure 3 of groove 2 on the filter rod (integument 1), its design feature is that the width and the degree of depth of groove all is to diminish gradually, so name gradual change groove.The cross sectional shape of groove can be for circle, V-arrangement, trapezoidal etc., shown in 2 among Fig. 3,1a, 1b.Gradual change groove among Fig. 1 also can be oblique setting, shown in the 2a among Fig. 1, promptly forms the gradual change groove of spiral on filter rod.The operating position of gradual change groove filter rod as shown in Figure 4, it with cigarette prop up 6 dock the back bond them in aggregates with yew paper 5.

Claims (2)

1, a kind of gradual change groove filter rod, it comprises filter core rod and forming paper thereof, it is characterized in that between forming paper and the filter core rod one deck integument being arranged, integument is provided with along the groove embossing of the axial gradual change of filter core rod, makes the groove that forms vertical gradual change between integument and forming paper.

2, filter rod according to claim 1, the gradual change groove embossing that it is characterized in that integument is a twill groove embossing, the spiral gradient twill groove between filter core rod cylinder formation integument and forming paper.
