Technical field

The invention relates to a teaching aid, in particular to a blackboard eraser dust-free cleaning device.

Background technique

Blackboard eraser is an indispensable teaching tool for teachers during class, and its use range is very wide. At present, most schools still use traditional chalk. When using traditional blackboard erasers, a large amount of dust is produced, which is harmful to the human body.

Traditional blackboard erasers generally consist of two parts: a back plate and an erasing cloth. During use, a large amount of chalk dust will adhere to the surface of the wiper. If it is not removed in time, the wiping effect of the blackboard eraser will be greatly reduced. To remove the chalk dust adhered to the surface of the blackboard, users can only rely on manual actions such as shaking, scraping, and flicking, which will still produce a large amount of dust.

Although there are currently dust-free chalks and blackboard erasers with vacuum functions on the market, the actual use results are not good. Chalk dust will still quickly adhere to the surface of the blackboard and cannot be effectively cleaned, affecting the use effect. , and cause problems such as dust pollution.
