High-frequency vibration blackboard eraser and controlling method thereof

Abstract

The invention provides a high-frequency vibration blackboard eraser and a controlling method thereof. The blackboard eraser comprises a shell body and a brush arranged on the lower part of the shell body, and further comprises a power supply module, a controlling module, a driving module, a micromotor unit and a transmission mechanism which are arranged in the shell body; the micromotor unit comprises a micromotor I and a micromotor II which rotate in opposite directions; the brush comprises a brushing block I and a brushing block II; the micromotor I controls the brushing block I to move leftand right via the transmission mechanism; the micromotor II controls the brushing block II to move left and right via the transmission mechanism; and the motion directions of the brushing block I andthe brushing block II are always opposite to each other. Automatic erasing can be conducted in a way that a user enables the brush to touch a blackboard; the micromotors rotate at a high speed and are convenient, rapid and high-efficiency; the brush are hollow and are arranged in a dual-row linear array, so wiped chalk dust falls naturally and the wiped and falling chalk dust is convenient to drain and no severe flying dust phenomenon is caused; volume and weight are reduced, and the situation that the user breaths in a lot of chalk dust which influences health of the user can be prevented; and brush hair of the brush is made of nanometer materials, the erasing effect on traditional blackboards is good and the brush is wear resisting.

Description

technical field [0001] The invention relates to the technical field of electronic blackboard eraser, in particular to a high-frequency vibration blackboard eraser and a control method thereof. Background technique [0002] Today, with the popularity of multimedia teaching, the traditional blackboard still retains its place because of its advantages of convenient writing and low cost. However, in today’s highly developed automation, there is no convenient and practical automatic blackboard eraser for commercial use. Traditional blackboard erasers usually have the following technical problem: [0003] 1. Wiping is time-consuming and laborious, and dust is flying; [0004] 2. It is easy to get dusty. Generally, after wiping it several times, it needs to be tapped for a while to shake off most of the chalk dust attached to it before it can be used normally; [0005] 3. As the usage time increases, more and more ash sticks to the felt wool of the blackboard eraser, making it...

AI Technical Summary

Problems solved by technology

[0003] 1. Wiping is time-consuming and laborious, and dust is flying;

[0004] 2. It is easy to get dusty. Generally, after wiping it several times, it needs to be tapped for a while to shake off most of the chalk dust attached to it before it can be used normally;

[0005] 3. As the use time increases, more and more dust sticks to the blackboard eraser felt, and the wipe becomes less and less clean

[0006] At present, many types of automatic blackboard erasers have been found, but their mechanical transmission structure is complicated, the wiping efficiency is not high, the volume is large, and the cost is high. Especially the blackboard eraser with a dust collection function module is larger and inconvenient to move. It limits its practicality, and there are some automatic blackboard erasers with dust storage design, which need to clean the pipe frequently and pour out the chalk dust in the storage box, which is not practical
