Problems solved by technology

[0002] At present, blackboards are mostly used in the teaching process. Although information-based education is becoming more and more popular, the mainstream teaching methods are still taught by our real teachers and written on blackboards. Therefore, blackboards are used in the entire teaching process. The middle blackboard still plays an important role, but it is understood that most of the blackboards currently in use cannot effectively isolate the interference of dust, and bring a lot of pollution. Therefore, the present invention is convenient to solve the problems caused by writing on the blackboard by fast dust removal. coming dust pollution
