Abstract
The utility model discloses a kind of inner core furrowfilter rod, it comprises inner core and outer shroud, described outer shroud parcel inner core, described inner core is made up of the first forming paper, groove fiber element paper and acetate silk filter core, and described acetate silk filter core is from inside to outside enclosed with the groove and the first forming paper that are formed by groove fiber element paper successively; Described outer shroud is made up of the second forming paper and acetate silk, and described the second forming paper is wrapped on described acetate silk; Described outer shroud and inner core form concentric structure; Compared with existing furrowfilter rod, " two-way crossing current effect " that described inner core furrowfilter rod produces promoted the filter effect of filter tip to flue gas greatly, compared with common filter stick, can reduce tar content in cigarette 2～5mg.
Description
Technical field
The utility model relates to the filter stick for the manufacture of cigarette filter, is specifically related to a kind of inner core furrowfilter rod.
Background technology
The groove of common furrowfilter rod is positioned in the outer rim of filter core, when cigarette suction, due to the low-pressure channel forming in groove, the part main flume of filter core outer rim changes flue gas trend, radially enter in groove, cellulose paper produces filtration to flue gas, and while flue gas flow rate slows down and the contact area of flue gas and acetate silk increases, and the filter efficiency of furrowfilter rod improves.Because the main channel of main flume is positioned at the axle core place of filter stick, the filter effect of groove to flue gas may have been limited in groove position in filter core outer rim.
The inner core of coaxial core filter stick is made up of common forming paper parcel acetate fiber, its outer shroud and inner core can be made with the tow at difference list dawn or total dawn, also can be filled to different density with the tow of same specification, improve the filter efficiency of filter tip thereby the pressure drop official post flue gas path between dependence inner core and outer shroud changes.On the heart circle of coaxial core filter stick, one group of groove is set, it may significantly improve the filter efficiency of flue gas.
Utility model content
The utility model has overcome in prior art groove position and has been positioned at and on filter core cylindrical, has limited the deficiencies such as the filter effect of groove to flue gas, based on the design feature of common furrowfilter rod and coaxial core filter stick, the utility model provide a kind of by the advantages of two kinds of filter sticks together, the inner core circle that is arranged on coaxial core filter stick by the groove of common furrowfilter rod is upper, the inner core furrowfilter rod that the filter efficiency of flue gas is significantly improved.
The utility model is by the following technical solutions: a kind of inner core furrowfilter rod, it comprises inner core and outer shroud, described outer shroud parcel inner core, described inner core is made up of the first forming paper, groove fiber element paper and acetate silk filter core, and described acetate silk filter core is from inside to outside enclosed with the groove and the first forming paper that are formed by groove fiber element paper successively; Described outer shroud is made up of the second forming paper and acetate silk, and described the second forming paper is wrapped on described acetate silk; Described outer shroud and inner core form concentric structure.
Further technical scheme is, described groove heats pressurization compacting by groove fiber element paper by groove device and forms.
In the technical program, be first set to overlap by the axle center of described inner core and the axle center of outer shroud, form coaxial core structure, thereby make inner core furrowfilter rod there is the structure of coaxial core filter stick, successively wrap up at acetate silk filter core the groove and the first forming paper that are formed by groove fiber element paper as axle center outward taking acetate silk filter core again, described groove heats pressurization compacting by groove fiber element paper by groove device and forms, and has been realized groove is arranged in the inner circle of inner core by above-mentioned setting.When cigarette suction, the low-pressure channel forming in groove has changed the trend of acetate silk partial fume in inner core and outer shroud, flue gas in acetate silk filter core in inner core is through groove fiber element paper and in the time that the intrafascicular flue gas of the acetate fibres in outer shroud radially enters groove through the first forming paper, and groove fiber element paper and the first forming paper all produce filtration to flue gas." two-way crossing current effect " in inner core and outer shroud slows down flue gas flow rate and the contact area of flue gas and acetate silk filter core increases, and the filter efficiency of whole filter tip significantly improves, and the tar content in flue gas obviously reduces.
Further technical scheme is, described groove be shaped as triangle, rectangle or trapezoidal.
Further technical scheme is, described the first forming paper is common forming paper or high filtration performance forming paper, and described the second forming paper is common forming paper or high porosity plug wrap paper.
The beneficial effects of the utility model are:
1. the design feature of integrated furrowfilter rod and coaxial core filter stick, appearance structure novelty, has the miscellaneous function of cigarette anti-fake;
2. " the two-way crossing current effect " of inner core and outer shroud further promoted the filter effect of filter tip to flue gas, compared with common filter stick, can reduce tar content in cigarette 2～5mg;
3. inner core furrowfilter rod is as base bars, with the compound composite filter that contains inner core groove of making of other filter stick, for filter stick harm reduction provides how optional technical scheme.
