Abstract

The utility model discloses an automatic dust-removing and dust-cleaning brush, composed of a brush body, a blade wheel, a dust raising brush, a dust collection box, a motor, etc. The dust raising brush driven by the motor to rotate to enhance the dust adsorbed on objects. The blade wheel and dust raising brush in a cyclone chamber rotate simultaneously to form negative pressure in a dust raising chamber, which forces the dust-air to flow into the cyclone chamber from the dust raising chamber and flow into a dust-collection chamber. The end of the brush is square, and the edge hair leans outward to remove the dust on rims and angles of structural objects. The brush contacts with objects through soft brush hair, which can remove the dust on scraggly surfaces. The rear part of the brush is provided with a lengthened rod to remove the dust on high places conveniently. The brush is practical and reliable.

Description

Automatic dust-removing and dust-cleaning brush

The utility model relates to absorbent brush.

Existing micro-cleaner is made up of whirlwind impeller and dust-collecting box etc., and it is that the negative pressure of utilizing impeller rotation to produce is drawn dust, and is not ideal enough to the pick-up performance of the dust that is adsorbed on body surface.Patent 86209589 was introduced a kind of electric dust-less blackboard and was wiped, and it is that hairbrush and impeller are closed in a Room, thereby can not reach the pick-up performance of expection.

The purpose of this utility model is to provide a kind of automatic dedusting absorbent brush of electronic wiping examination automatic dust absorption.Can be used as window cleaner, blackboard eraser, replacement feather duster etc., it simple in structure, use easy to carry.

The utility model is achieved in that driven by motor impeller ［ 9 ］ and brush dish ［ 10 ］ rotation, bristle is kicked up the dust of body surface, the impeller rotation, dusty gas in the airborne dust chamber is sucked cyclone chamber, send into dust-collecting box, air-flow is discharged after the filter course on the dust-collecting box filters, and reaches the purpose that dust removal is gathered dust.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is a structure chart of the present utility model.

Below in conjunction with accompanying drawing the utility model is done general introduction in detail, the utility model mainly is made up of main brush body ［ 1 ］, cover plate ［ 2 ］, motor ［ 3 ］, battery ［ 4 ］, extension bar ［ 5 ］, dust-collecting box ［ 6 ］, trap ［ 7 ］, brush body ［ 8 ］, impeller ［ 9 ］, brush dish ［ 10 ］.It is with airborne dust, whirlwind, gathering dust is separated in three Room, and combining in the powered brush of one, the annular diaphragm plate ［ 11 ］ of brush body ［ 8 ］ separates brush dish ［ 10 ］, impeller ［ 9 ］, forms airborne dust, whirlwind two Room, in the center airborne dust, whirlwind two Room are communicated with, passage becomes the air inlet of cyclone chamber.Impeller is constantly drawn the dusty gas in the airborne dust chamber during work, forms negative pressure simultaneously in the airborne dust chamber, keeps away negative dust and escapes.Around the bottom of brush body ［ 8 ］ bristle is arranged, and have enough spaces to allow air to flow into, make air, excrete, form the air-flow circulation and reach the purpose of gathering dust through cyclone chamber, dust storage chamber continuously from external inflow airborne dust chamber.The blackboard eraser of patent 86209589 closes hairbrush, impeller in a Room, brush body must be close to body surface during work, prevent that dust from escaping, but this moment, the whirlwind impeller did not have inlet channel, thereby impeller can not realize air-breathing normally, degassing function, can not reach desirable dust collection effect.

The utility model is designed to form as Fig. 2 with brush dish ［ 10 ］, and two arc limit fan shape bristles are only arranged, and stays bigger space, and two bigger fan-shaped cavities are arranged in the no hair-fields of brush dish, and it both had been convenient to airborne dust, is convenient to dusty gas again and flows into cyclone chamber.Fan-shaped hairbrush both can prevent that dust from escaping, and bristle is is in use worn and torn evenly.

Around the brush body ［ 8 ］ bristle the same with the brush dish arranged, it can play supporting role not only, prevent that dust from escaping, and supplies with outside the air-flow of airborne dust chamber, can also be as auxiliary wiping examination.Its end be designed to square and the limit hair oblique outward, can wipe the dust of works edge.Because brush body is all contacted with bristle with wiping the surface, can wipe the rough surface of examination when therefore pressing a little.

Dust-collecting box ［ 6 ］ can take off the dust of outwelling collection.Valve ［ 7 ］ is that dust leaks when preventing the brush body inversion.For ease of wiping the dust of examination eminence, this bristle portion is equipped with simple load and unload extension bar ［ 5 ］.

This brush has good dedusting, pick-up performance owing to make airborne dust, dust suction combined integrated.Brush entirely outside motor and the extension bar, all can be made of plastic, therefore in light weight, purposes is wide, easy to use.

Claims (1)
