Abstract

The utility model discloses an anion air purifier. The air purifier comprises an enclosure with vent holes, a dust collecting electrode, corona wires and a high-voltage pulse circuit board, wherein the dust collecting electrode, the corona wires and the high-voltage pulse circuit board are arranged in the enclosure; the dust collecting electrode is connected with the anode of the high-voltage pulse circuit board; the corona wires are connected with the cathode of the high-voltage pulse circuit board; the plurality of corona wires are arranged and fixed on a fixed frame; the dust collecting electrode is a dust collecting board fixed on the inner wall of the enclosure; a notch in which the fixed frame can slide is formed in the lateral enclosure of the dust collecting board; after discharging sharp points of the corona wires slide on the fixed frame and are inserted into the notch, the discharging points of the corona wires are opposite to the dust collecting board. The anion air purifier can be used for cleaning dust on the corona wires conveniently, and prevents dust from returning to the air once again.

Description

Negative ion air-cleaner

Technical field

The utility model relates to air cleaning unit, is specifically related to negative ion air-cleaner.

Background technology

Existing for removing air dust, the negative ion air-cleaner of peculiar smell generally comprises dust collecting electrode (or claiming collecting plate) and the corona wire (or claiming corona discharge electrode) being arranged in casing, the positive pole of dust collecting electrode access high-voltage pulse circuit plate, the negative pole of corona wire access high-voltage pulse circuit plate, after energising, between the two poles of the earth, form high voltage electric field, make the discharging sharp-angle of corona wire emit a large amount of negative ions, negative ions is neutralized by corona wire, anion and free ion shift to dust collecting electrode, and be adsorbed on airborne grit, make dirt powder charged, under the effect of electric field force, motion arrives dust collecting electrode, and for positively charged dust, shift to corona wire and be attached on this corona wire, therefore, the continuous dust stratification of corona wire meeting, after long-time use, to adhere to a large amount of dusts, be difficult to clean, after shutdown, these dusts also have an opportunity in air, again to affect air quality by returning.

Utility model content

Technical problem to be solved in the utility model, is just to provide negative ion air-cleaner, can conveniently clean the dust on corona wire, avoids dust again to return in air.

For solving the problems of the technologies described above, the technical scheme that the utility model is taked is as follows:

Negative ion air-cleaner, comprise the casing with air-vent, and be all installed on dust collecting electrode, corona wire and the high-voltage pulse circuit plate in this casing, dust collecting electrode is connected with the positive pole of high-voltage pulse circuit plate, corona wire is connected with the negative pole of high-voltage pulse circuit plate, described corona wire is many, arrangement is fixed on a fixed frame, described control of dust is very fixed on the collecting plate on casing inner wall, on the casing of this collecting plate side direction, have the notch sliding for fixed frame, the discharging sharp-angle of described corona wire is relative with collecting plate after fixed frame slides insertion notch.

Further, the both sides of described fixed frame are equipped with described notch; Described fixed frame correspondence is made as two, and arranges and be fixed with many corona wires respectively on two fixed frames; Described collecting plate correspondence is made as two, is fixed on the forward and backward inwall of casing; The discharging sharp-angle of the corona wire on two fixed frames is relative with the collecting plate being positioned on the forward and backward inwall of casing respectively.

Further, described collecting plate is equidistantly distributed with a plurality of through holes, and the discharging sharp-angle of described corona wire is relative with the hole heart of each through hole respectively.

Further, described air-vent equidistantly distributes at the forward and backward outer wall of casing respectively.

Further, the outboard end of described fixed frame is provided with rib, and described notch is for stopping the ladder mouth of rib.

Compared with prior art, the utlity model has following beneficial effect:

Corona wire of the present utility model can be extracted out with coordinating of notch through fixed frame, after extraction fixed frame, can conveniently clean, and meanwhile, the setting of rib can coordinate with ladder mouth, and rib is stopped by ladder mouth, prevents that fixed frame from falling in casing; In addition, the setting of two fixed frames and two collecting plates, has strengthened the electric discharge dust collecting effect of corona wire.

The specific embodiment

Negative ion air-cleaner as shown in Fig. 1～2, comprise the casing 1 with air-vent 11, and be all installed on dust collecting electrode, corona wire 3 and the high-voltage pulse circuit plate (not shown) in this casing 1, dust collecting electrode is connected with the positive pole of high-voltage pulse circuit plate, and corona wire 3 is connected with the negative pole of high-voltage pulse circuit plate.Wherein, corona wire 3 is five, arranges and is fixed on a fixed frame 4, and each corona wire 3 is all connected with the negative pole of high-voltage pulse circuit plate.

As shown in Fig. 2～3, control of dust is very fixed on the collecting plate 2 on casing 1 inwall, collecting plate 2 equal intervals are distributed with a plurality of through holes 21, on the casing 1 of these collecting plate 2 side direction, have the notch 12 sliding for fixed frame 4, the discharging sharp-angle 31 of corona wire 3 is relative with collecting plate 2 after fixed frame 4 slides insertion notch 12.Particularly, the both sides of the fixed frame 4 of the present embodiment are equipped with notch 12; Fixed frame 4 correspondences are made as two, and arrange and be fixed with five corona wires 3 respectively on two fixed frames 4; Collecting plate 2 correspondences are made as two, are fixed on the forward and backward inwall of casing 1; The discharging sharp-angle 31 of the corona wire 3 on two fixed frames 4 is relative with the hole heart of each through hole 21 that is positioned at the collecting plate 2 on the forward and backward inwall of casing 1 respectively.In addition, the number of corona wire 3 also can be set to two above any amount according to dedusting, the needs that purify air.
