Abstract
The composite filter tip of this invention is that it installs a porous article between the cut tobacco and the shortened ordinary filter tip. said porous article is made from paper, plastics, ceramic film and metal material and is a circular tube in shape with one open end and one close end, on the circular face of the close end there are opened holes. Compared with the ordinary filter tip, said invention can reduce the tar content in smoke by 15-47% and the CO content can be reduced 20-30%.
Description
The present invention relates to tobacco business, specifically provide a kind of cigarette that between pipe tobacco and common filter tip, is added with the cigarette composite filter tip of porous device formation and this filter tip is housed.
As everyone knows, the tar in the cigarette smoke is the carcinogenic Main Ingredients and Appearance of smoker.In order to reduce tar in the flue gas, people have increased filter tip on cigarette, as acetate fiber filter tip, composite filter tip etc.Though these filter tips have tangible crown_interception to tar in the flue gas, they are lower to dilution or the adsorption capacity of CO, and particularly the cost of these filter tips is higher, have limited their extensive use and development.
The object of the present invention is to provide a kind of cost low, hold back tar efficient height, dilution CO ability strong new cigarette filter tip.
Feature of the present invention is that a porous device (3) is installed between common filter tip (2) and pipe tobacco (7), and porous device is made by materials such as paper, plastics, ceramic membrane, metals, is the cylindric of an end opening one end sealing, has hole (6) on the face of blind end garden.The garden face thickness of porous device is 0.04～2mm, and garden barrel thickness is 0.04～2mm, and the garden tube length is 0.08～20mm, and garden tube external diameter is identical with filter stick bag paper internal diameter.The number in hole is 1～10 on the face of garden
4Individual, single hole area is 10
-4～1mm
2, the distribution in hole can be uniformly, also can be heterogeneous, the shape in hole and its function are irrelevant to can be garden shape, triangle, square, rectangle or irregularly shaped.
Can have hole (5) on the garden barrel of above-mentioned porous device, the number in its hole is 0～10
4Individual, single hole area is less than 25mm
2, the hole can even or heterogeneous being distributed on the barrel of garden, and the shape in hole and its function are irrelevant, can be garden shape, triangle, rectangle or irregularly shaped.
In the cigarette composite filter tip of the present invention, between porous device (3) and pipe tobacco (7) common filter tip (1) can be housed also, the length of common filter tip (1) is 0～20mm.The length of common filter tip (2) is 3～25mm, and they are by acetate silk (being called for short the vinegar fibre), and polypropylene fibre tow (being called for short the third fibril bundle) or paper filter stick are made.Filter tip (1) and (2) one main effect is in order to adapt to high speed cigarette spicing machine that present cigarette factory the using needs of cutting to the 120mm filter stick.In fact, can and directly be connected with pipe tobacco the porous device lengthening, filter tip (2) can be used the harder material of other material instead.Adopt composite filter tip of the present invention to compare with common filter tip, the fibrous raw material of use is chewed in its filter can save 65%.Simultaneously, test shows is equipped with the NEW TYPE OF COMPOSITE filter tip and compares with the cigarette that common cellulose acetate filter is housed, and tar content reduces by 15～47% in its cigarette smoke, and CO content descends 20～30%.
Another feature of the present invention is between porous device (3) and filter tip (2) 0～5 layer of pad (8) to be arranged, and pad is by filter paper, toilet paper, and materials such as cotton are made.
The present invention is the making of porous device for convenience, permission is combined into one garden face and garden tube, and once " injection moulding " moulding, also garden face and garden tube can be made then respectively and be bonded together, perhaps with garden face and garden tube without bonding and directly be installed in the filter tip, the garden face is towards filter tip (2), and garden tube openend contacts with filter tip (1) or pipe tobacco (7).
The present invention can beat air vent (4) in order to dilute the content of CO in the flue gas on yew paper.Its aperture is 0.01～1mm, and the number in hole is 0～10
4Individual, the hole is even or non-uniform Distribution along yew paper garden week, and the hole will be concentrated and be beaten near the yew paper pipe tobacco and filter tip connection or the connection.In addition, compound filter cigarette filter tip of cigarette of the present invention and pipe tobacco tipping are right, can keep the slit less than 2mm between cigarette paper and the filter stick bag paper, and outside air is unimpeded to be entered among the novel filter tip so that make.If filter stick uses the bag paper of high-air-permeability or uses the bag paper that has had openning hole, then the part of air vent will be connected with hole (5) on the tube of porous device garden on the yew paper.Measurement shows, novel filter tip punches very little to the Cigarette Draw Resistance influence on yew paper, smoker is not had the sense of ＂ gas leakage ＂ yet, but it produces very strong diluting effect to CO.
Being thermodynamics and spraying the bump principle of utilization of the present invention.
By the law of thermodynamics as can be known, gas removes H at normal temperatures
2Beyond He, joule of general gas--Thomson coefficient m be that it obeys adiabatic equation on the occasion of, thereby generally temperature decline during the gas adiabatic expansion:
T/To=(P/Po)
(r-1)/γWherein, To, Po are the temperature and pressures before gas expands, and T, P are the temperature and pressures after gas expands, and γ is a heat capacity ratio.The resistance to suction of cigarette can be approximately 2000Pa, thereby when smoking, vacuum of the inner generation of common filter tip (2) is about the little space of 98000Pa, flue gas enters the instantaneous of this little space by aperture on the face of porous device garden, approximate meet gas adiabatic expansion process, thereby flue gas will descend promptly suddenly by temperature behind the porous device.Moreover, hole on the face of porous device garden is generally the hole, garden, diameter is about 0.1-0.15mm, individual effect is about 120-80, every mouthful of flue gas average size of smoker is about 35 milliliters, about 2 seconds of every mouthful of suction time, the speed of flue gas stream in the tube of porous device garden is about 0.4 meter per second in the time of can calculating suction thus, and flue gas stream can be up to 12 meter per seconds by the speed during aperture on the face of garden.Thereby in when suction, the temperature of flue gas is in hurried decline, and high-speed impact has formed the tar of condensation shape and is blocked on the tow face near the filter tip (2) of garden face aperture again, thereby has realized efficiently removing the purpose of tar content in the flue gas.
Obviously, the number or the diameter in hole on the suitable change garden face, and the resistance to suction that changes cigarette all can realize artificially reconciling the purpose of tar content in the flue gas, to satisfy the requirement of different trade mark cigarette and different smoker mouthfeels.
The present invention will be further described below in conjunction with accompanying drawing and example.
