Description

A kind of laser boring filter stick

Technical field

The utility model relates to the filter stick of a kind of cigarette, particularly cigarette.

Background technology

The structure of cigarette comprises that the inside is filled with the cigarette body of tobacco, and the columniform filter stick that is connected in the back.During smoking, the gas that cigarette evaporated also contains various harmful substances except tobacco flavor is arranged, like tar, nicotine, carbon monoxide or the like.Through the diluting effect of air, can reduce the intake of these harmful substances.Therefore high air permeability cigarette paper arises at the historic moment with preparatory perforated tipping paper (yew paper), and particularly in recent years, the punching technology of yew paper has had swift and violent development, and wherein, quantitatively punching is effectively the simplest with laser.

Because cigarette props up in combustion process, during aspirating, bringing out the main flume that comes from cigarette body is high concentration collection, the continuous aerosol systems that changes, and flue gas particle is in a liquid state, and its water content is about 20% of droplet size, thereby they are spherical in shape.The flue gas of this state can filter through the filter pore on the filter stick.The overall structure of filter stick can be divided into the columniform filter core that connects with the cigarette body that wraps tobacco, yew paper and the filter stick paper wrapper that wraps in the filter core outside.So-called laser boring filter stick; Just be meant the filter stick middle part after moulding, rely on high-octane laser, yew paper, filter stick paper wrapper are punched and goed deep into the filter stick certain depth form small pore; Promptly constitute said filter pore; So stamp a plurality of small pores, and a plurality of filter pore is arranged bunchiness continuously, just forms cloth hole line.When in sucking the process of cigarette, flue gas can be diluted, thereby improve the cigarette venting quality effectively, reaches to fall burnt purpose like this.

Cloth hole line on the conventional at present laser boring filter stick all is in the form of a ring, has one to three circle and does not wait.With two circles is example, if yew paper is launched (yew paper is a rectangle after launching), can see, cloth hole line is two and grows the parallel straight line in limit with yew paper.That is to say that the cloth hole line on the filter stick of moulding has two, be the circle around the filter stick outer surface, and this circle is positioned on the radial section of filter stick.As previously mentioned, cloth hole line is rearranged by the filter pore continuously, and therefore the filter pore on this circle cloth hole line has just formed relation facing each other on the radial section of filter stick, and the dilution mode of this cloth pore structure is called the dilution of symmetrical expression line formula.But, because the filter pore is facing each other, flue gas being produced parallel cutting thereby the air of entering just forms convection current, this will make the dilution factor of flue gas too high, though realized the purpose of dilution, this perfume (or spice) of tobacco can not get effective reservation.

The utility model content

The purpose of the utility model is in order a kind of flue gas dilution function that both had to be provided, to keep the laser boring filter stick of the tobacco original flavor in the flue gas again effectively.

The solution that the utility model solves its technical problem is:

A kind of laser boring filter stick; Comprise columniform filter stick body and be coated on the outer field yew ply of paper of filter stick body; Has the one or more cloth hole line that rearrange continuously by a plurality of filter pores on the said yew ply of paper; Have at least on the cloth hole line, have two filter pores, the radially cutting plane angle in an acute angle of their line and filter stick body.

The beneficial effect of the utility model is: the utility model is through changing the trend of cloth hole line; Make that the filter pore no longer is a state facing each other; The dilution that had so both kept filter stick itself; Avoided the cross-ventilation that the filter pore forms between mutually again and made the dilution factor of flue gas too high, kept this perfume (or spice) of tobacco in the flue gas effectively, let the quality of cigarette, mouthfeel further improve.The utility model simple and ingenious structure, the filter stick that can be widely used in as cigarette uses.
