Abstract

The utility model relates to a cigarette filter stick capable of improving a selective harm-reducing effect. The cigarette filter stick capable of improving the selective harm-reducing effect is composed of a tow filter core and forming paper wrapping the tow filter core, wherein the tow filter core comprises a selective absorption filter core section close to cut tobacco and an ordinary filter core section close to an end portion of a cigarette, a flow guide piece is arranged between the selective absorption filter core section and the ordinary filter core section, and a gap exists between the flow guide piece and the inner side of the forming paper. Due to the fact that the cigarette filter stick capable of improving the selective harm-reducing effect is provided with the flow guide piece, the flow guide piece increases the air flow resistance in the central position of a filter tip, the air flowing method of main flow smoke is changed, the air flow is forced to transfer towards two sides, absorption materials are capable of contacting the more smoke more evenly, and therefore the utilization rate is improved. In addition, macromolecule smoke components of and non-target adsorbates pass through selective absorption materials less, and therefore damage to other absorption materials is reduced, in other words, the phenomenon of blockage of material holes or intoxication is reduced.

Description

A kind of cigarette filter rod that improves the selective harm reduction effect
Technical field
The utility model relates to the manufacturing technology field of cigarette, relates in particular to a kind of cigarette filter rod that improves the selective harm reduction effect.
Background technology
In the prior art, common binary compound filter candle is generally 25mm or 30mm is long, close pipe tobacco end is that functional filter stick is interval, it is the selective absorption filter core, conventional design is 15mm, what adopt is to add a certain amount of Characteristic Adsorption material in common tow filter core, is thereafter common tow filter core, and its conventional design is 10~15mm.And its filter stick formation paper, according to the designing requirement of flue gas dilution rate, two sections filter sticks all adopt the same section forming paper with certain air permeability.This binary compound filter candle, the Characteristic Adsorption material that adds in its functional filter stick interval some special harmful substance in can the elective reduction flue gas reduces cigarette harmfulness, smoke perfume is not caused too large impact simultaneously.So-called selective harm reduction refers to deduct the specific nuisance decline percentage behind the tar decline percentage, that is: elective reduction rate=chemical composition reduced rate-tar reduced rate.Yet in actual use, the Characteristic Adsorption material that this binary compound filter candle adds, because the characteristics of aerodynamics, when cigarette mainstream flue gas was flowed through filter stick, centre gas velocity and throughput were maximum, and peripheral air stream speed and throughput are low, referring to Fig. 1, lines with arrow among Fig. 1 represent flow line, and the longer expression flow velocity of flow line is larger, and aerosol particle is more.And be sprayed at whole section filter core place during selective absorbent, and this flue gas composition that has just caused peripheral selective absorbent to touch is less, and utilization rate reduces; And the component upon adsorption that the material of center touches too much causes overload, the centre material also touches a large amount of other bulky grain flue gas compositions simultaneously, cause the material hole blocked or the sorptive material intoxicating phenomenon occurs, thereby reduced the selective absorption efficient of this part material, the effect of its selective harm reduction is far below the data in laboratory.And because the Characteristic Adsorption material price is higher, large like this consumption will increase the production cost of cigarette greatly.Simultaneously, although that these sorbing materials have is certain selective, but still be difficult to avoid impact on smoke perfume, so consumption is excessive also inadvisable.
This shows how to improve the actual selection harm reduction effect of cigarette filter rod, is the present technical issues that need to address in this area.
