Abstract
The utility model provides a guide filter rod with a hemispherical resistance sucking rod. At present, smoke quickly flows in the filter rod along the middle part of the filter rod and cannot disperse to four sides, so the filter effect of wire beams is imperfect. The guide filter rod of the utility model comprises a wire beam core rod (1) and a forming paper (2) covered at outer layer. The axial core line of the wire beam core rod (1) is embedded with an airtight hemisphere (3) of which the diameter is 1/4 to 1/2 of the diameter of the filter rod, the hemisphere (3) is located on the part which is 2 to 17 mm apart from the joint of the wire beam and the wire beam core rod (1), and the highest point of the hemisphere surface faces the direction of the tobacco shred. After the smoke enters the filter rod, because of the guide action of the hemisphere, the linear flow states of the smoke in traditional filter rods are changed, a large number of the smoke disperse to the edge of the filter rod along the hemisphere surface, the wire beams of the complete filter rod can be fully used, and the utilization ratio of the fiber wire beam is effectively improved.
Description
Technical field
The utility model belongs to the filter stick of cigarette, and 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 utility model 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 utility model is realized above-mentioned purpose through following technological means: the water conservancy diversion filter stick that is provided with the hemispherical resistance drawing stick; It is made up of the stranded core rod 1 and the forming paper 2 of outer parcel; On stranded core rod 1 axial line, be embedded with the hemisphere 3 air-locked, that diameter is filter stick diameter 1/4～1/2; Hemisphere 3 is positioned at apart from pipe tobacco and stranded core rod 1 junction 5～17 millimeters position, and the hemisphere face peak is over against the pipe tobacco direction.
Preferably, on stranded core rod 1 axial line, be embedded with the hemisphere 3 air-locked, that diameter is filter stick diameter 1/3～2/5.
Hemisphere 3 is positioned at apart from pipe tobacco and stranded core rod 1 junction 6～14 millimeters position.
In the process of smoking cigarette; Main flume in pipe tobacco part along streamlined flow, arrive filter stick after because the guide functions of hemisphere; Changed the streamlined flow form of flue gas; Make that the edge to filter stick disperses most of flue gas along the ball surface, slowly draw close again to the center through behind the certain distance, as shown in Figure 3.
The utlity model has following beneficial effect:1. on the axial line of cigarette tows plug, be embedded with air-locked hemisphere, 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 hemisphere; Changed the streamlined flow form of flue gas in traditional filter stick, made most of flue gas disperse, through slowly a part of again behind the certain distance to center flow along the edge of hemisphere surface to filter stick; 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 hemisphere 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 hemisphere is embedded in the filter stick tow, can not change its overall appearance.
