Abstract
The utility model belonging to the manufacture technical field of cigarettes relates to a cigarette filter tip with a damper, which comprises a filtration fiber rod and a packing paper. The cylindrical damper which is the same as external diameter of the filtration fiber rod and packed by the packing paper is installed between the two filtration fiber rods. The cylindrical damper is a cylinder structure with single via or multiple via in the middle part. The cylinder structure is made of wood and paper material which will not produce injurant at work temperature of lower than 80 Celsius degrees. When cigarettes are being smoked, mainstream of smoke goes through the filter tip with the damper and flowing situation and flowing route of the smoke are changed, which is helpful to the filtration of injurant in the smoke (especially particle matter). The utility model can reduce tar content effectively, which is characterized in good effect, reasonable structure, convenience and utility and others.
Description
Technical field
The utility model relates to a kind of cigarette filter, belongs to field of cigarette producing technology.
Background technology
Traditional cigarette filter, it is the filter fiber rod of the garden cylindricality made by the tow that one section paper bag is wrapped up in, under swabbing action, main flume passes through from whole filter tip, a part of harmful substance in the flue gas is effectively filtered, filter efficiency is generally below 50%, and the flue gas that enters the oral cavity from the filter tip tail end still contains a large amount of residual harmful substances, so filter effect is undesirable.
Summary of the invention
The utility model is at the deficiencies in the prior art, and a kind of simple in structure, cigarette filter that has the joint door that strainability is good is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of cigarette filter with the joint door, comprise filter fiber rod and wrapping paper, wherein, between two sections filter fiber rods, be provided with the cylindrical joint door identical, and wrap up by wrapping paper with the filter fiber rod outside diameter.
Described cylindrical joint door is the middle garden column structure that single-pass hole or multi-through hole are arranged.
The material of described cylindrical structure, selecting for use in operating temperature is below 80 degrees centigrade the time, the materials such as wooden or papery that do not produce harmful substance are made.
The utility model is provided with identical with the filter fiber rod outside diameter cylindrical joint door between two segment filter fiber rods, this three part is wrapped up in fixingly with paper bag simultaneously, and total length and traditional filtering mouth are quite or slightly long (the slightly long thickness that has increased joint that is meant).During suction, main flume stream changes the flow regime of flue gas and glide path by having the filter tip of joint door, helps harmful substance in the flue gas (particularly granule phase substance matter) and filters.The utility model is compared with traditional filter tip following variation has been taken place:
When 1 main flume flows to the joint door, flow area diminishes suddenly, the flue gas stream that is in filter fiber bar edge position is forced to the central area and is concentrated, thereby increase the lateral flow of flue gas, it is the glide path lengthening, and because the individual thread cellulose fiber in the filter fiber rod mostly is vertical distribution, the lateral flow of flue gas bumps the easier and fibroin surface of the granule phase substance matter in the flue gas and is trapped.
When 2 main flumes save door by filter tip, because effectively flow area diminishes, flow velocity increases, according to principle of inertia, make that the less gaseous substance of proportion quickens to pass through easily in the flue gas stream, and granule phase substance matter such as the bigger drop of proportion, solid particle are bigger because of inertia, quicken slowly, filtering fibroin or a joint door surface is trapped easilier.
Because the harmful substance tar in the flue gas, nicotine, BaP, nitrosamine etc. mostly are the bigger grain phase constituent of molecular weight, the filter tip that therefore has the joint door has better reducing tar and reducing harm effect than traditional filtering mouth.And advantages such as rational in infrastructure, convenient and practical are arranged.
