Abstract

The utility model relates to an electric air purifier, belonging to the electric air purifier and composed of an air negative ion generator and an electrostatic dusting device. The electric air purifier is characterized in that the interiors of the box bodies of the electric air purifier are parallel and are connected fixedly with an electric discharge grid of a high-voltage electrostatic negative electrode in pairs and with a dust collecting grid of a high-voltage electrostatic positive electrode and the air outlet of the purifier is connected fixedly with a negative ion generating electrode of the high-voltage electrostatic negative electrode. The electric discharge grid has corona for the electric wind which is formed by electric discharge and flows to the dust collecting grid and makes dust in the air have negative charge, thus, the dust can be deposited at the dust collecting grid. The negative ions generated from the negative ion generating electrode and clean air are discharged from the electric air purifier. The electric air purifier has the advantages of simple structure, low noise and saving power.

Description

Electric air purifier

The utility model belongs to indoor air purifier.

At present, the existing air purifier that is made of negative aeroion generating means and electrostatic precipitation device all uses electric fan air draught and air draft." physiatrics " (People's Health Publisher, in March, 1984 front page, standard book number 14048,4548 is seen the 183rd page) " biofilter " introduced be the typical structure of this air purifier.This machine with electric fan with in the unpurified air inhalation machine, through the static filter screen particle such as dust is wherein filtered out, and make air ionization, produce the positive and negative air ion of some, flow through the then static cathodic electricity grid of voltage 3000V, air ion in the air-flow is negative electrode absorption, and negative air ion is discharged with purifying the back air.Because this machine uses electric fan air draught air draft, has than great machinery noise and air agitation, increases power consumption, the structure relative complex.

The purpose of this utility model provides a kind of low noise, economize on electricity, simple in structure, the indoor air purifier that is made of negative aeroion generating means and electrostatic precipitation device.

The utility model is finished as follows:

The clarifier tank ends has air inlet and air outlet, and inner parallel and paired arrangement connects the discharge grid of HV generator negative pole and connects the control of dust grid of the positive level of HV generator.Discharge grid and control of dust grid are made by the hardware (as steel pipe) of less surface curvature, the discharge grid are inlet scoop and the discharge spike is housed towards control of dust grid surface dorsad, the discharge spike is strong corona discharge under the high-pressure electrostatic effect, make surrounding air generate a large amount of anions, under the effect of the high-voltage electrostatic field that a pair of discharge grid and control of dust grid constitute, move to the control of dust grid, drive the surrounding air molecular motion and form electric wind, cause negative pressure at clarifier casing air inlet, extraneous dust laden air is inhaled in the clarifier casing, negative electricity on the grit ingress of air anion band under above-mentioned electric field and electric wind effect, flies to the control of dust grid and is adsorbed deposition.Air adds the flow speed and direction air outlet through several actings in conjunction to discharge grid and control of dust grid electric wind and electric field.At close air outlet, be fixed with the negative aeroion generation utmost point that connects the HV generator negative pole, hardware (as steel pipe) by less surface curvature is made, towards air outlet and control of dust grid bearing dorsad, the surface takes place extremely the discharge spike is housed in negative aeroion, under the high-pressure electrostatic effect, and strong corona discharge, make surrounding air generate a large amount of anions, flow out clarifier from air outlet with purifying the back air.Clarifier repeats the above-mentioned course of work, purifies air thereby reach, and regulates the effect of anion concentration in the air.

Because of using high-pressure electrostatic, the utility model forms electric wind, impel air to enter and flow out air purifier, the noise that does not have machine operation to produce, very little to air agitation, and economize on electricity, simple in structure is arranged, the advantage of long service life is particularly suitable for family, hospital, school and ultrapurification chamber etc. the place of noise limit strictness is purified air, and regulates the usefulness of anion concentration in the air.

Below with reference to accompanying drawing a kind of concrete structure of the present utility model is described in detail:
