Problems solved by technology

[0002] The blackboard is one of the indispensable teaching equipment in the school teaching work. It is easy to write and provides great convenience for teachers to write blackboard writing on the spot in the classroom. However, when the blackboard is full of writing, it is necessary to erase the handwriting for the next class. When used by teachers, chalk dust flies during the erasing process, which seriously affects the health of students in the classroom and the teaching environment in the classroom. Some electric dust removal equipment is disclosed in the prior art, but there is still a phenomenon of poor dust suction effect
