Abstract
The present invention relates to a cigarette filtration system, belonging to the field of cigarette and filtration technology. Said invention is characterized by adopting nano filter to make filter tip or filter element of cigarette so as to filter toxic substances of cigarette.
Description
The priority that the China that the application requires August 9 in 2006 to submit to applies for CN200610029828.5.
(1) technical field:
The present invention relates to cigarette filtering system, belong to cigarette and filtration art.
(2) background technology:
At present cigarette filter material comprises acetate fiber and filters outer and the add-on type paper bag is wrapped up in, the leftover of bolt of cloth, and active carbon, adhesive-bonded fabric, nanofiber or the like is as the preparation of the patent No.: a CN200410084223.7 functional nanometer short fiber; CN200410011618.4 cigarette filter is made of crust, filter core, it is characterized in that: the thin-walled liquid capsule that is mounted with dress liquid aided filter medium at least one in filter core; CN200510010716.0 the invention relates to the cigarette manufacture field, and particularly cigaratte filter manufacturing more particularly, is by applying the selective absorbent of some as adsorption layer on the filter tip forming paper; CN03142133.4 makes trouble according to above technology, and the pore size filter size can't guarantee.Cigarette filter can make in filter tip cover or the filter tip and entangle that cigarette or filter core are installed in the cigarette and or in the tobacco pipe and/outside.The U.S. is developed into a kind of filter element recently, and nanotube plays a part diaphragm in the filter element.The basis of nanofilter is vertically to place double-layer nanometer cast mould, nanotube with artificial synthesis in the steam condition deposit on nitrogenize silicon wafer-based (or other materials).Be full of silicon nitride in the hollow place of nanotube, scientist makes and is vertically fixed on the diaphragm of being made up of nanotube on the substrate.Utilize acid washing method to discharge the nanotube two ends, thereby make the diaphragm of " penetrating ", adopt the diaphragm ability controlled filter pore size of forming by nanotube on the substrate.
(3) summary of the invention:
Make trouble (comprising nanofiber) for solving existing cigaratte filter, the shortcoming that effect is bad, the present invention adopts nanofilter to make filter tip cover or filter tip or filter element filtering cigarette noxious material, and the present invention has simple in structure, effective advantage.
The present invention finishes by following technical measures:
The present invention sucks position installation nanofiltration material (sheet, diaphragm, volume, piece) filter tip/cigarette holder/cigarette end cigarette, adopts to embed, and pastes, and insertion and other modes are installed.
(4) description of drawings:
Below in conjunction with accompanying drawing structure of the present invention is described further:
Fig. 1 is the enforceable structure chart of cigarette filtering system of the present invention.
Wherein: 1 is filter tip, and 2 is nanometer (aperture) filtering material.
Fig. 2 is the enforceable another kind of structure chart of cigarette filtering system of the present invention.
Wherein: 21 is filter tip, and 22 is the nanofiltration material, and 23 is filter course and/or functional layer.
(5) specific embodiment:
Embodiment 1: structure of the present invention as shown in Figure 1, filter tip 1, nanofiltration material 2; In filter tip 1 the inside and/or central and/or outside and/or interlayer adopt and embed, paste, insert, an above nanofiltration material 2 is installed in rotation.
Embodiment 2: filter tip 1 and/or nanofiltration material 2 and/or cigarette are installed flush mounting, nanofiltration material 2 is adopted fixing and/or movable and/or portable and/or rotary installation filter tip 1 the inside and/or outside and/or outside, cigarette the inside, adjust filter area.
2 one of nanometer (aperture) filtering materials and/or a plurality of composition adopt the multiple aperture nano structural material of oxide and/or nitride and/or carbon nano tube structure material and/or polymer and/or metal and/or plastics and/or pottery and/or elasticity and/or composite and/or other material to make.
Nanofilter comprises the nanotube diaphragm of being made by other materials, nanotube pipe and other shapes.
In sum, more than be part embodiment of the present invention, but be not in order to restriction the present invention.All according to creative spirit of the present invention and pattern, filter tip install that nanometer (aperture) filtering material changes a little all should be in protection scope of the present invention the inside.
Claims (3)
