Existing air processor commonly used mainly comprises parts such as blower fan, airstrainer, electrostatic air cleaner, photocatalyst reaction module.Wherein airstrainer mainly is the coarse filtration dust in air.Electrostatic air cleaner is used to capture fine solid particle, and it is to utilize electrostatic force to realize a kind of dedusting and purifying device that airborne solid or liquid particle and air-flow are separated.The discharge electrode of electrostatic air cleaner and dust collector pole are connected high voltage direct current respectively, and keep an electrostatic field that is enough to make gas ionization; When dusty gas passes through the electric field of two interpolars, around discharge electrode under the effect of highfield ionization takes place, form gas ion and electronics and also make powder dust particle charged; Particle after charged under electric field action to dust collector pole motion and on dust collector pole, deposit; Thereby reach the purpose that dust, air are separated.When dust reaches certain thickness on the dust collector pole, can continue after clearing up to use.The photocatalyst reaction module is utilized UV-irradiation noble metal catalyst material (TiO2), carries out physics and chemical reactions such as a series of photo catalytic reduction, to remove pollutants such as airborne bacterium, virus and toxic gas.
Existing this type of air processor, the structure of its electrostatic air cleaner generally are in the cross section is the strip dust collecting pole plate of " Jiong " font, a conductive filament are set as discharge electrode along the battery lead plate direction; Dust collecting pole plate and discharge electrode connect the high voltage direct current of opposed polarity separately, thereby form electrostatic field in dust collecting pole plate; The air-flow that is driven by blower fan is during through electrostatic field, in the air with molecule charged in electric field, adsorbed by the dust collecting pole plate of different in nature electrode and under the effect of electric field force, thus reach the purpose that purifies air.The electrostatic air cleaner of this structure in use, " Jiong " font structure of dust collecting pole plate easily produces carbon distribution; And the conductive filament of discharge electrode is when clearing up or change, easy deformation, bending and produce the tip, even can rupture; These all can influence the real work efficient of air cleaning unit.If conductive filament fracture simultaneously because of spark appears in the electric arc effect, might be lighted the laying dust on the dust collecting pole plate, become disaster hidden-trouble.Conductive filament as discharge electrode in use causes that because of metal fatigue is out of shape discharge is uneven, has both shortened the service life of itself, also can influence air purification effect.
The photocatalyst reaction module of existing in addition air processor is coated on the photocatalyst catalysis material and is on the cellular or flat filter screen, and is few with the contact area of air, can not give full play to the good characteristic of noble metal photocatalyst material.The light source of its use is from fluorescent tube, and energy consumption is big and the life-span is shorter.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of the air processor of prior art, and proposes a kind of highly effective air treating apparatus.It adopts the structure of the supporting circle hole shape dust collecting pole plate of taper discharge electrode, and uses spongy filter screen to carry photocatalyst material, has air-treatment quality better, efficient height, energy savings and characteristics such as easy to install.
The purpose of this utility model can reach by taking following technical measures:
Design, a kind of highly effective air treating apparatus of manufacturing comprise blower fan, screen pack, electrostatic air cleaner 1, photocatalyst reaction module 2 and control circuit board; Described electrostatic air cleaner 1 comprises discharge electrode 11, dust collector pole 12 again; Described photocatalyst reaction module 2 comprises photocatalyst net 21 and luminous tube 22; It is characterized in that: described discharge electrode 11 comprises at least one spray point 111; Described dust collector pole 12 is provided with the circular hole 121 that is complementary with described spray point 111.

Fig. 1 is the structural representation of the utility model highly effective air treating apparatus;
Fig. 2 is an electrostatic air cleaner circuit theory schematic diagram;
Fig. 3 is the electrostatic air cleaner circuit diagram.
The specific embodiment
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.
A kind of highly effective air treating apparatus comprises blower fan, screen pack, electrostatic air cleaner 1, photocatalyst reaction module 2 and control circuit board; Described electrostatic air cleaner 1 comprises discharge electrode 11, dust collector pole 12 again; Described photocatalyst reaction module 2 comprises photocatalyst net 21 and luminous tube 22; Described discharge electrode 11 comprises at least one spray point 111; Described dust collector pole 12 is provided with the circular hole 121 that is complementary with described spray point 111.
Under the effect of blower fan 7, air flows to outlet from the import of the utility model highly effective air treating apparatus embodiment.In fact, the priority position that blower fan is installed can can't produce very big influence to result of use of the present utility model according to different situation design and installations.
Air at first passes through coarse filtration net 4, the preliminary airborne bulky grain dust of elimination.Enter electrostatic air cleaner 1 then, because be added with high voltage direct current between the discharge electrode 11 of electrostatic air cleaner 1 and the dust collector pole 12, just produce an electrostatic field, its power line locates to be cone shape at spray point 111 with around the circular hole 121.Air is flowed through spray point 111 when arriving circular holes 121, the cutting power line, and airborne fine solid particle is charged, and is adsorbed under electric field action on the pole plate of dust collector pole 12 around the circular hole 121, and losing electric charge becomes neutral solia particle.The corona ball occurs simultaneously because of the dielectric strength of electric-field intensity greater than air, thereby at the place, tip of spray point 111, its ambient air molecule is ionized and forms gas ion and electronics and make powder dust particle charged.Airborne bacterium, virus are in the moment of air ionization shocked by electricity carbonization and death.Electrostatic field can produce the ozone of trace when work, also can play the effect that eliminates the unusual smell with bacteria growing inhibiting.The impurity such as floating dust that the air that comes out from electrostatic air cleaner 1 is not adsorbed through the 5 further eliminations of a very thin filter screen again.Then, air enters photocatalyst reaction module 2, the photocatalyst reaction module is utilized UV-irradiation noble metal catalyst material (TiO2), carries out physics and chemical reactions such as a series of photo catalytic reduction, to remove pollutants such as airborne bacterium, virus and toxic gas.Cleaning clean air at last is discharged in people's the living space by outlet.
Because the ion that spray point 111 ionized airs are produced moves to circular hole 121 and forms ion stream, also can drive air and flow, can play good dedusting, eliminate the unusual smell and kill the effect that removes virus and suppress bacterium, also alleviated the live load of blower fan simultaneously.
