Abstract
The utility model discloses a cigarette tar filter which is invented to solve the problem of the incomplete filtration of the existing cigarette filter tip. The filter comprises a hollow cylindrical cavity body with the outer dimension of 7.4mm, the height of 3mm, the thickness of 0.5mm; the center of one end surface of the cavity body is provided with an exsuction hole with the diameter of 0.8 mm, which is communicated with the hollow part of the cavity body, and the inner surface of the cavity body at one side of the exsuction hole is an uneven surface; the other end of the cavity body is provided with two exsuction holes with the diameter of about 0.4 mm, which are communicated with the hollow part of the cavity body and symmetrically arranged at the two sides of the center of the cavity body, and the center to center distance of the two exsuction holes is 4.6mm. The structure can effectively clean out hazardous ingredients such as tar, nicotine, etc., in the smoke during smoking, keep the original aroma of the cigarette and render the cigarette more tasty and refreshing; besides, the cigarette bar filter has relatively low cost due to simple structure and small volume.
Description
Technical field
The utility model relates to a kind of cigarette coke tar filter.
Background technology
Cigarette discharges 38 kinds of toxic chemical substances when burning, wherein oxious component mainly contains tar, carbon monoxide, nicotine, dioxin and irritating smog etc.Tar all has infringement to oral cavity, throat, tracheae, lung.Tar deposition in the tobacco smoke has been destroyed the function of fine hair on lung's fine hair, phlegm is increased, and makes bronchus that chronic pathology take place, and tracheitis, pulmonary emphysema, pulmonary heart disease lung cancer just can produce.60 years old ratio with the future trouble PUD D of people of inhaling pharynx according to statistics is 74%, and 60 years old ratio with the future trouble PUD D of the people of non-smoking only is 4%, and this is a startling numeral.
Human body is to the suction of harmful substances such as tar, nicotine when reducing smoking, and people have invented cigarette filter; But used the people of cigarette holder all to know, existing cellulose acetate filter is the tar in the filtering flue gas well.After smoking Linear Leaf Speedwell, a lot of tar are just arranged in the cigarette holder, after the toilet paper cleaning, can see that the tar on the toilet paper is enough to allow the smoker draw a cold breath.
The utility model content
In order to overcome above-mentioned defective, it is a kind of simple in structure that the purpose of this utility model is to provide, and volume is little, the cigarette coke tar filter that filterability is strong.
For achieving the above object, cigarette coke tar filter of the present utility model comprises an outside dimension 7.4mm, highly is the hollow cylindrical cavity of 3mm, cavity wall thickness 0.5mm; Be provided with the sucking-off hole that the diameter that is connected with the cavity hollow bulb is 0.8mm at cavity one end end face center, the cavity inner surface of sucking-off hole one side is uneven; Be provided with two inlet holes that are connected with the cavity hollow bulb about diameter 0.4mm at cavity other end end face, two inlet holes are symmetrically distributed in both sides, cavity center, and the centre-to-centre spacing of two inlet holes is 4.6mm.
Further, inwardly be formed with the boss of cross section for annular in the sucking-off hole, cavity inner face upper edge of described sucking-off hole one side, described boss height is 0.4mm, and the wall thickness of boss is 0.2mm.
Adopt said structure, can effectively remove oxious components such as the tar in the smog, nicotine in the smoking process, and keep the original fragrance of cigarette, make cigarette more tasty and more refreshing, and because it is simple in structure, volume is little, so cost is lower.
Description of drawings
Fig. 1 is the utility model cigarette coke tar structure of filter schematic diagram.
Fig. 2 is that the utility model cigarette coke tar filter shown in Figure 1 is installed in the structural representation on the cigarette filter.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing.
As shown in Figure 1, cigarette coke tar filter of the present utility model comprises that an external diameter B is 7.4mm, and height A is the hollow cylindrical cavity of 3mm, and cavity wall thickness E is 0.5mm; Be provided with the sucking-off hole that the diameter C that is connected with the cavity hollow bulb is 0.8mm at cavity one end end face center, the cavity inner surface of sucking-off hole one side is uneven H; Being provided with two diameter D that are connected with the cavity hollow bulb at cavity other end end face is inlet hole about 0.4mm, and two inlet holes are symmetrically distributed in both sides, cavity center, and the centre-to-centre spacing of two inlet holes is 4.6mm.Inwardly be formed with the boss of cross section for annular in the sucking-off hole, cavity inner face upper edge of described sucking-off hole one side, described boss height G is 0.4mm, and the wall thickness F of boss is 0.2mm, helps filtering more tar like this.
Above-mentioned hollow cylindrical cavity can adopt various materials to make, during manufacturing as shown in Figure 1, it can be divided into two parts, link together by means such as bonding or hot pressing then, preferably adopt plastics to make, when made of plastic, can adopt injection molded one time if having ready conditions, make production technology so that simplify.
During use, as shown in Figure 2, only needing has inlet hole one end towards filter tip one side with cigarette coke tar filter of the present utility model, and the opposite side in sucking-off hole is got final product toward the outer side.
In summary, the utility model is simple in structure, volume is little, and cost is lower.It can effectively remove oxious components such as the tar in the smog, nicotine in the smoking process, and keeps the original fragrance of cigarette, makes cigarette more tasty and more refreshing.
