Problems solved by technology
[0003] At present, teachers usually need to write a lot of words with chalk on the teaching board during teaching work, and a lot of dust will be generated during the writing process. Teachers can easily inhale a lot of dust when reading by the blackboard for a long time, which will endanger their own health. Dust will also be generated during the wiping process, and a large amount of dust floats in the air, seriously affecting the air environment of the entire classroom, which is not environmentally friendly
