Abstract
The invention provides a cigarette filter rod with a draw resistance sheet. At present, since most smoke in the filter rod rapidly flows along the middle of the filter rod and is rarely diffused around, the filtering effect of tows is greatly reduced. The cigarette filter rod consists of a tow core rod (1) and wrapping paper (2) which wraps the outer layer of the tow core rod (1). The draw resistance sheet (3) is a nontoxic and non-air-permeable circular sheet which is 3-8mm thick and has a diameter being 20-50 percent of the diameter of the filter rod. The draw resistance sheet (3) is axially buried on the axis of the tow core rod (1) and is arranged at a position which is 5-17mm distant from the junction between cut tobaccos and the tow core rod (1). After the smoke enters the filter rod, under the flow guide effect of the draw resistance sheet, the linear flow form of the smoke in the traditional filter rod is changed, most smoke is retained by the bottom surface of the draw resistance sheet and is diffused towards the edge of the filter rod, the tows of the entire filter rod are fully utilized and the utilization of the fiber tows is effectively improved.
Description
Technical field
The invention belongs to the filter stick of cigarette, specifically belonging to shape and structure is the filter stick of characteristic.
Background technology
As everyone knows; Contain multiple harmful substances in the cigarette smoke; These oxious components are deposited in the human body and can produce multiple disease by internal organs such as initiation lung, respiratory tract and stomach after the smoking, though harm of smoking is in health as you know, cigarette having refreshed oneself, the multiple function of restoring consciouness; Suitably smoking can make people's excitement, excites inspiration, increase work efficiency, so smokers still are difficult to smoking cessation.
At present, cigarette props up generally to adopt and installs filter stick additional and alleviate the harm of smoking to human body, and the tow in the conventional fibre filter stick generally all is that straight bundle distributes; Owing to added glue and the influence that rolls the process mechanism characteristic; It is uneven that the resistance to suction of filter stick distributes, and generally is middle little, big on every side.Therefore, flue gas mostly flows along the centre of filter stick in filter stick fast, seldom to diffusion all around, makes the filtering effect of tow occur in the zone line of filter stick basically, and the filter efficiency of tow is uneven because of smoke distribution, and has a greatly reduced quality.And Cigarette Draw Resistance not only directly influences the complexity of consumer's smoking cigarette, and with the burst size of safety and sanitation indexs such as tar content in cigarette, nicotine content in smoke, CO content substantial connection is arranged also.Therefore, existing filter stick being improved, make to reach a balance between filtering rod and the filtering cigarette harmful substance, is an important job.
Summary of the invention
The present invention aims to provide and a kind ofly can improve resistance to suction in the middle of the filter stick, cigarette smoke is had guide functions, thereby make whole filter stick tow can both effectively filter the filter stick of the oxious component in the flue gas.
The present invention realizes above-mentioned purpose through following technological means: the cigarette filter stick that is provided with the resistance to suction sheet; It is made up of the stranded core rod 1 and the forming paper 2 of outer parcel; Resistance to suction sheet 3 is that 3～8 millimeters, diameter are the disk of filter stick diameter 20～50% for nontoxic, airtight, thickness; Resistance to suction sheet 3 is embedded on the axis of stranded core rod 1 vertically, and is positioned at apart from pipe tobacco and stranded core rod 1 junction 5～17 millimeters position.
Preferably, said resistance to suction sheet 3 is that 4～6 millimeters, diameter are the disk of filter stick diameter 30～40% for nontoxic, airtight, thickness.
Resistance to suction sheet 3 is positioned at apart from pipe tobacco and stranded core rod 1 junction 6～14 millimeters position.
Resistance to suction sheet 3 is solid disks or hollow disk-shaped.
In the process of smoking cigarette; Main flume in pipe tobacco part along streamlined flow, arrive filter stick after because the guide functions of resistance to suction sheet; Changed the streamlined flow form of flue gas; Make that the edge to filter stick disperses most of flue gas along resistance to suction sheet bottom surface, through slowly a part of to center flow, as shown in Figure 3 again behind the certain distance.
The present invention has following beneficial effect:1. on the axial line of cigarette tows plug, be embedded with air-locked resistance to suction sheet, increased the cigarette smoking resistance to suction, the amount that makes main flume get into human body reduces accordingly, has also just reduced the soakage of human body to harmful substance in the flue gas.
2. after flue gas gets into filter stick; Because the guide functions of resistance to suction sheet; Changed the streamlined flow form of flue gas in traditional filter stick, most of flue gas is blocked by resistance to suction sheet bottom surface and disperses to the edge of filter stick, through slowly a part of to center flow again behind the certain distance; Make the tow of whole filter stick be able to sufficient utilization, effectively improved the utilization rate of fibre bundle.
3. flue gas gets into filter stick, when flowing to tow and resistance to suction sheet junction, forms a cooling area, makes high-temperature flue gas become the relatively low flue gas of temperature, makes that the aerosol in the flue gas can well be cut filter by the filter stick fiber.
4. the preparation method is simple, as long as the resistance to suction sheet is embedded in the filter stick tow, can not change its overall appearance.
