Abstract

The invention discloses an electrostatic environment-friendly blackboard eraser, and belongs to the technical field of blackboard erasers. The electrostatic environment-friendly blackboard eraser comprises a handle, a shell body, an adsorption assembly, a main roller, an auxiliary roller, felt cloth, and a dust collection assembly, wherein an opening is formed in one end of the shell body, and thehandle is installed at the other end of the shell body; the main roller is rotationally installed in the shell body and parallel to the length direction of the opening of the shell body; the auxiliary roller and the main roller are arranged in parallel; the felt cloth is annularly arranged and surrounds the main roller and the auxiliary roller; the dust collection assembly comprises a dust collection frame, a first electrostatic adsorption sheet, a second electrostatic adsorption sheet and an ash taking plate, the dust collection frame is arranged in the shell body and located at one screw-inside of the main roller, and a long opening corresponding to the width of the felt cloth is formed in the dust collection frame and opened towards the shell body; and the ash taking plate is arrangedat one side opposite to the first electrostatic adsorption sheet, of the dust collection frame, one end of the ash taking plate is fixed to the dust collection frame, the other end of the ash takingplate makes contact with the felt cloth, and the width of the ash taking plate corresponds to the width of the felt cloth. The invention provides a simple electrostatic environment-friendly blackboarderaser capable of preventing dust from falling off through static electricity.

Description

technical field [0001] The invention relates to the technical field of blackboard erasers, in particular to an electrostatic environment-friendly blackboard eraser. Background technique [0002] According to relevant national reports, the statistical data in 1993 showed that the teachers and students of my country would inhale about 200 grams of chalk dust per person every year in class, and suffer from about 20% / year of respiratory tract, lung disease and cancer. This shows how great the health hazards of chalk dust are to teachers and students. At the same time, the flying chalk dust pollutes the personal hygiene of teachers and students very large, such as the flying chalk dust makes the collars, cuffs, hair, and bodies of teachers and students unable to do without its annoying shadow. [0003] Patent 201310103069.2 discloses a self-rotating roller dust-absorbing blackboard eraser, including a blackboard eraser and a control system, the motor is powered by a battery pack...
