The air filting material that existing air purifier is used in the market, or employing nonwoven, its clean-up effect is poor, filter efficiency is low, or while adopting high efficiency filter paper, its air drag is large, service life is short, and therefore, under the so serious situation of current atmosphere pollution, the used air filting material of air purifier can not meet broad masses' demand.

In air, contain various bacteriums and virus, photocatalyst and ultraviolet ray are the instruments of topmost simple and easy kill bacteria in various air purifiers at present, the shortcoming of photocatalyst maximum is exactly that nano titanium oxide must have large sunlight or ultraviolet lamp irradiation just can work, so the quartz burner of special wave band (UV-A) must be installed in air purifier, not only increased the volume of clarifier, cost, because the life-span of quartz burner only has 2000～4000 hours, so change half a year less than just needing, cost is high, use trouble, this technology is refused to use by user institute gradually.Although and the good UA-C of bactericidal effect ultraviolet ray is effective, human body is had to injury effect, for having, child's family is inapplicable especially.

Air purifier adopts at present air filtration and sterilization technology also have: air negative ion generator, ozone generator, electrostatic filter, high pressure generator, water atomization plant, charcoal absorption etc., these branches of technology department produce secondary pollution, part technical sophistication, hold at high price, partial volume is excessive, so be not suitable for being applied in acceptable cheap and good-quality, the high-efficiency air filtering of ordinary people and sterilizing and air-cleaning device.

In the processing air that air purifier adopts at present, the technology of pernicious gas mainly contains: charcoal absorption, high pressure generator, low temperature plasma etc.

Active carbon is good pernicious gas adsorbent, and its shortcoming one is that air drag is large, the 2nd, cannot regenerate after saturated, and mainly at present adopt NACF, although air drag reduces, adsorption efficiency obviously declines.

Low temperature plasma is to process at present pernicious gas best-of-breed technology in air, current maximum obstacle, the one, volume is excessive, reach desirable clean-up effect, need larger treated length, the 2nd, reach desirable clean-up effect and can generate ozone, produce secondary pollution, clarifier has become stink generator and new pollution sources.

Therefore, be necessary to provide a kind of new technical scheme to solve the problem of above-mentioned existence.

Summary of the invention

Object of the present utility model is the deficiency for current domestic Related product, provide that a kind of clean-up effect is better, filter efficiency is higher, and the air purifier with sterilizing function, and the concentration of main pernicious gas in air can be can be controlled under national standard, realize the multiple purification function of air purifier, and can not produce secondary pollution.
