Basic principle of the present utility model is: in air-conditioning, the airtight interior space, contaminated air is under the effect of blower negative pressure, enter prefilter by the air inlet suction by the coarse filtration net, airborne bulky grain dust is arrested on the screen pack, played the effect of elementary dedusting, avoided simultaneously fibrous dust to enter electrostatic field, caused " flashover " phenomenon and affect the normal operation of electrostatic precipitator. Enter the electrostatic precipitator of honeycomb one needle bar type electric field through the air of prefilter. Electric field pass to high voltage direct current and with the electrode of positive polarity as discharge electrode, keep an electrostatic field that is enough to make gas ionization, form positive corona discharge, make gas generation ionization, generate a large amount of electronics, cation and anion. Pass into the cation in the particle absorption motion in the dusty gas of electric field this moment and lotus powers on, under the effect of electric field force, to negative electrode (being the dust collector pole honeycomb) motion and be deposited on its inwall, the aerosol of submicron order is all captured by cottrell. Gas filters by the granular deodorant activities charcoal of immersion-type coconut palm with the air channel subsequently, in order to the HH in the adsorbed gas₃, CO, SO2, NOx and other peculiar smell, discharged by blower fan through the deozonize activated carbon filtration again, the fan outlet place arranges anion generator with anion releasing simultaneously. Because the principle of Brownian movement, indoor continuous ringing (being generally 1 hour 3～5 times) makes room air reach purification, pure and fresh condition.

This machine is because the effect of high-pressure electrostatic, at a large amount of ozone of this zone generation of electric field and active carbon, makes to enter in this regional air bacterium and killed by ozone.And ozone makes the indoor ozone concentration of emission reach standard-required because of the absorption of deozonize active carbon with filter and be suppressed.

Room air defecator prefilter adopts the fiber filter felt, adopts folding type to increase its filter area and dust containing capacity on the structure; Electrostatic precipitator adopts the version of honeycomb one needle bar type electric field, has increased specific collection area greatly, and its electric field meets the classical formulas of electric precipitation fully---the Eugen Deutsch formula.Deodoriser adopts active carbon dipping new and high technology, and structure adopts M type layout, increases filter area, reduces filtration velocity; The electrostatic field power supply adopts constant current high-frequency and high-voltage Switching Power Supply, has avoided the increase of electric field with the laying dust thickness that gathers dust, thus the defect end that output current descends efficiency of dust collection is descended, and this power supply has the function of overload protection and short-circuit protection demonstration.

This air cleaner collection gathers dust, sterilization, deodorization, release anion four functions are one.
