Abstract

The invention relates to an electrostatic dust collection board wiper which comprises a shell and a hairbrush. A magnetic induction power generation device is arranged in the shell. The electrostaticdust collection board wiper further comprises a boosted circuit, a rectifier circuit, a filter circuit and a voltage stabilizing circuit sequentially and electrically connected with the magnetic induction power generation device; a dust adsorption conductive piece is fixed onto the shell; and a part, held by people, on the shell is in conductive connection with a negative pole end of the voltage stabilizing circuit. During a blackboard wiping process, a solenoid cuts a magnetic induction line, so that a current is generated in a solenoid closed circuit; and then an unstable alternating currentis converted into a stable direct current through the boosted circuit, the rectifier circuit, the filter circuit and the voltage stabilizing circuit, and a stable electric field is formed between thedust adsorption conductive piece and a blackboard, so that dust moves to the dust adsorption conductive piece and is finally stored in a dust storage cavity, and the problem of low dust collection efficiency of an electrostatic dust collection board wiper in the prior art is solved.

Description

technical field [0001] The invention relates to an electrostatic dust removal board eraser. Background technique [0002] At this stage, most teachers still use blackboards for teaching during class. Flying chalk dust not only causes great pollution to the surrounding environment, but also causes serious harm to the human body. Therefore, how to remove the chalk dust in the process of wiping the blackboard quickly and effectively has always been a concern. [0003] The dust removal methods of common dust-absorbing blackboard erasers are generally divided into negative pressure adsorption, electrostatic adsorption, and combined adsorption of the two. Generally, electric energy is used to drive a fan or metal to generate electrostatic dust removal, so most of them use an external power supply. The authorized announcement number is CN205238962U, and the Chinese patent document whose authorized announcement date is 2016.05.18 discloses a dust-removing blackboard eraser, which i...
