Abstract
The utility model relates to a trapping filter combiner for embossed grooves, comprising a tow core rod (1) and molding paper (4) wrapped on the outer layer, wherein a layer of inlayer paper (2) wrapping the tow core rod is arranged between the tow core rod and the molding paper, the inlayer paper is distributed with 1 to 500 U-shaped embossed grooves (3) along the circumference of the tow core rod, and the two side faces and the end face of each embossed groove are respectively provided with 1to 200 small drainage holes. The embossed grooves can be in the types of U, V, X, Y and Z as well as a polygon. Because the embossed grooves compress the tow core rod towards a center, the central density is enhanced and partial smoke is forced to flow through the small drainage holes and finally enters the grooves, and because a space is magnified suddenly, the grooves play the role of a cold well so that partial smoke is condensed. By making the smoke pass through multiple grooves and small drainage holes repeatedly in such a way, the smoke is repeatedly subjected to the actions of two trapping mechanisms of diffusion and deposition as well as intensive flowing in a filter nozzle, and thus the particles in the smoke are greatly trapped.
Description
Technical field
The utility model relates to tobacco product, particularly a kind of filter fibrous type mouth rod of cigarette.
Background technology
The mechanism that fibrous type mouth rod is removed particle matter in the flue gas is exactly that mechanicalness is filtered, and its filter efficiency is relevant with size (quality and diameter), the movement velocity of particulate, the diffusion (distribution situation and the time of staying) of particulate in filament of particulate in the flue gas.Because particulate passes through the time very short (0.04 second) of mouth rod, the diameter of particulate very little (0.2 micron), and filametntary diameter (20 microns) is bigger 100 times than the diameter of particulate.Therefore, the fiber of mouth rod mechanical filter (holding back) rate that particulate is caused is very little.
It is exactly to make particulate continuous and fiber collision in flow path that fibrous type mouth rod mechanicalness is filtered, and forms inertia impact.Because the quality of the movement velocity of particulate and particulate is all little, the momentum that motion produces just can not be big, and therefore, inertia impact is to the contribution of cigarette filter tip efficient also very little (account for total clearance 2%).
The disordered motion of particulate causes that the collision with fiber promptly forms the diffusion deposition.Studies show that the motion of low quality particulate is more more than high-quality person, the mistakes rate effect that when low flow velocity, causes because of diffusion just generally, this has been the time lengthening that stops in filter tip owing to particulate, makes particulate have more opportunity and spreads in filament.The particle removal that is caused by the diffusion deposition accounts for 65% of total clearance.
When particulate very closely flows through fiber and collides with it direct interception function will take place, this mechanism is relevant with the size of particulate, and irrelevant with the flow velocity of particulate.This particulate of being removed by direct interception function accounts for the 30%-35% of total clearance greatly.
At present, cigarette props up generally to adopt and installs fibrous type mouth rod additional and alleviate the harm of smoking to human body, and the tow in the conventional fibre type mouth rod 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 tip distributes, and generally is that the center is little, big on every side.Therefore, flue gas mostly flows along the center of filter tip in filter tip fast, seldom to around diffusion, the mechanicalness filtering effect of tow occurs in the central area of filter tip substantially, the mechanicalness filter efficiency of tow is because of the smoke distribution inequality, and has a greatly reduced quality.Hold back efficient to satisfy the requirement of people for what improve fibrous type mouth rod, satisfy people again to the smoking demand simultaneously, must change original filter fibrous type mouth bar structure, reduce harmful ingredients in flue gas better and reduce tar content to reach to health.The fibrous type mouth rod that a kind of forming paper is provided with the longitudinal groove embossing has appearred in the recent period, it significantly improves than the filter effect of general fibre type mouth rod, but owing to just vertically hold back, flue gas is still comparatively smooth by groove, still is not unusual ideal to the efficient of holding back of flue gas.
