Description

Foaming body Special-shaped filter rod
Technical field
The utility model relates to a kind of filter stick for cigarettes, particularly a kind of foaming body Special-shaped filter rod.
Background technology
The filter stick for cigarettes extensively existing on front market mainly by cellulose acetate tow through shredding, apply triacetyl glycerine, roll-forming, cut and obtain.In aspiration procedure, flue gas directly passes from filter stick middle part conventionally, not good to the filter effect of flue gas harmful substance.And on existing market Special-shaped filter rod product to have a small amount of tow burr irregular consistent with geometry, in production process waste more serious, and its complex manufacturing, production efficiency low cost is high, quality is unstable.
Utility model content
The purpose of this utility model is to provide a kind of can more effectively filter harmful substances from flue gases and production technology is simple, cost is low, stay-in-grade foaming body Special-shaped filter rod.
According to an aspect of the present utility model, foaming body Special-shaped filter rod is provided, comprise integument and filter core, filter core comprises outer filter core and inner filter core, inner filter core connects vertically and is embedded in outer filter core, outer filter core is provided with the first flow deflector, and inner filter core is provided with the second flow deflector, and the first flow deflector, the second flow deflector are arranged on the varying cross-section of filter core.By flow deflector is set, make flue gas can in inner filter core and outer filter core, intersect circulation, improved the adsorptivity to harmful substances from flue gases.
In some embodiments, the first flow deflector is arranged on 1/3 place of the outer filter core length to rise near pipe tobacco end.The first flow deflector is set on filter core outside, forces the circulating direction of flue gas to change, improved the adsorptivity to harmful substances from flue gases.
In some embodiments, the second flow deflector is arranged on 2/3 place of the inner filter core length to rise near pipe tobacco end.The second flow deflector is set on inner filter core, forces the circulating direction of flue gas again to change, make full use of the inner space of filter core, improve the adsorptivity to harmful substances from flue gases.
In some embodiments, inner filter core is wrapped with high air permeability cigarette paper, is coated with tobacco harm reduction layer on high air permeability cigarette paper.By high air permeability cigarette paper being set and applying one deck tobacco harm reduction particle on high air permeability cigarette paper, can further reduce the oxious component in flue gas.
In some embodiments, the cross section of inner filter core is hexagram, quincunx, cross, herringbone or six fonts.By variations such as inner filter core geometries, can play anti-fake effect.
In some embodiments, have hollow on inner filter core, the cross section of hollow is that hexagram, quincunx, cross, herringbone are as shape or six fonts.Hollow is set on inner filter core, can improves the circulation effect of flue gas, the variations such as hollow geometry, also can play anti-fake effect.
In some embodiments, the material of inner filter core and outer filter core is expanded material.Make that foaming material shaped technique is simple, cost is low, steady quality and material safety non-toxic.
In some embodiments, on inner filter core and outer filter core, all have some open cells, the percent opening of described abscess is 65%~84%, cell density is 10 7~10 12individual/cm 3, abscess aperture is 10 μ m~300 μ m.Abscess in material both can make flue gas smoothly by filter stick, the harmful substance in again can effectively catching flue gas, and result of use is good.
