Abstract

The invention discloses a blackboard eraser device based on automatic control and a using method thereof. The blackboard eraser device comprises a gear and a rack engaged with the gear; a motor is connected to the gear and connected with a brush, wherein the motor drives the brush to move in the rack direction; both of the two ends of the brush are connected with rollers; and guide rails allowingthe rollers to roll are arranged under the rollers, and the length of each guide rail is no less than that of the rack. The problems that an existing automatic cleaning blackboard eraser is complex instructure, poor in using effect and high in cost are solved.

Description

technical field [0001] The invention belongs to the technical field of automatic control mechanical devices; in particular, it relates to an automatic control-based eraser device and a use method thereof. Background technique [0002] In recent years, many workers have researched many such products, such as electric rotary erasers and common vacuum cleaners, but they have not been popularized because of ineffective use, complicated structures and high prices. And some projector teaching application has been popularized at present, but also because teaching efficiency is not high and not favored, and existing multi-functional brush wall is because price is more expensive, and the electric wiper that has is difficult to popularize because of complex structure. Contents of the invention [0003] The invention provides an automatic control-based eraser device, which solves the problems of complex structure, poor use effect and high cost of the existing automatic cleaning erase...
