Abstract

The invention discloses a dust-collecting blackboard eraser which comprises a blackboard eraser body, an erasing surface, transmission mechanisms, a dust collecting mechanism and a dust storage mechanism; the erasing surface is arranged on the bottom surface of the blackboard eraser body; the transmission mechanisms are arranged at the two sides of the erasing surface; each transmission mechanism comprises a friction wheel and a transmission gear group; each friction wheel is connected with the input end of each transmission gear group; the dust collecting mechanism is positioned in the blackboard eraser body; and the dust storage mechanism is arranged on the back surface of the blackboard eraser body. The dust-collecting blackboard eraser disclosed by the invention utilizes friction force to drive the mechanism to rotate to generate static electricity, is energy-saving and environmentally-friendly; and meanwhile, the dust-collecting blackboard eraser collects dust through static electricity, is simple in structure, is high in dust collecting efficiency and is convenient to use.

Description

A kind of dust absorption blackboard eraser
The invention belongs to teaching aid technical field is and in particular to a kind of dust absorption blackboard eraser.
Background technology
Classroom teaching can commonly used blackboard eraser, when wiping chalk writing using traditional blackboard eraser, can produce Substantial amounts of chalk dust, sucks chalk dust for a long time, is unfavorable for the health of academics and students, and the dust absorption blackboard eraser being currently known is in the back of the body Portion installs electric dust cleaner additional, and chalk dust is sucked collecting bin by the blast being produced by fan, and not only noise is big, and power consumption, Need frequent charging or change battery it is therefore necessary to design a kind of new dust-removing blackboard eraser.
Content of the invention
According to above the deficiencies in the prior art, the technical problem to be solved is to propose a kind of dust absorption blackboard eraser, Electrostatic Absorption is produced by the rotation that the roller on blackboard eraser drives electrostatic friction pulley and collects chalk dust, solve traditional blackboard Wiping can not collect dust and electric dust absorption blackboard eraser power consumption is big, the big problem of noise, has energy-conserving and environment-protective, the high spy of dust collection efficiency Point.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is:A kind of dust absorption blackboard eraser includes blackboard eraser Body, wiping face, drive mechanism, dust collection mechanism and Chu Chen mechanism, described blackboard eraser body bottom surface is provided with wiping face, described wiping face both sides It is provided with drive mechanism, described drive mechanism includes friction pulley and driving gear set, the input of described friction pulley and driving gear set End connects, and described dust collection mechanism is located in blackboard eraser body, and the described blackboard eraser body back side is provided with Chu Chen mechanism.
Described blackboard eraser body side wrap has the shirt rim of blocks dust, and described shirt rim is soft rubber skin.Described friction Wheel is located in the blackboard eraser body of wiping face both sides respectively, and described friction pulley is wrapped with rubber sleeve.Described dust collection mechanism includes quiet Electric generator, dust arrester, scrape hawk and lead ash-pit, be provided with wire between described electrostatic generator and dust arrester, described dust arrester Be provided with and scrape hawk, described scrape hawk lower end and be provided with lead ash-pit, described ash-pit of leading is connected with Chu Chen mechanism.Described electrostatic generator Including glass wheel and silk wheel, described glass wheel and silk wheel CONTACT WITH FRICTION, described driving gear set include rotate forward outfan and Inversion output terminal, described rotating forward outfan is connected with glass wheel, and described inversion output terminal is connected with silk wheel, and described dust arrester is Metal roller.Described dust arrester includes the first dust arrester and the second dust arrester, and described first dust arrester passes through wire and glass wheel Connect, described second dust arrester is connected with silk wheel by wire.Described wiping face be felt face, described wiping face two ends be provided with for It is fixed on the buckle in blackboard eraser body.Lid for clearing up dust is set on described Chu Chen mechanism.
Present invention has the advantages that:The frictional force producing when the present invention is by blackboard wiping drives electrostatic generator to rotate and produces Raw electrostatic, and positive and negative electrostatic is transferred to corresponding metal cinder catcher respectively, thus adsorbing chalk dust, reduce dust pollution, then With scraping hawk, the dust on metal cinder catcher is peeled off, collect to Chu Chen mechanism, realize being uniformly processed.
