Description

technical field [0001] The invention relates to the technical field of primary school learning facilities, in particular to a self-cleaning blackboard for primary school students. Background technique [0002] The blackboard does not specifically refer to the black board surface. In the traditional sense, it is a plane that can be written repeatedly.

Problems solved by technology

[0003] The existing blackboard is fixedly installed on the wall. When the words written by the teacher are high, the height of the primary school students is not enough, and the dust cannot be cleaned, which brings inconvenience to the cleaning. The existing blackboard needs to be cleaned manually, which increases labor intensity. Wipe the blackboard A large amount of dust is generated, and primary school students are easy to inhale it into their bodies, which will affect their health and affect the classroom environment. There are still a lot of chalk dust on the blackboard after being wiped, which will cause inconvenience to the teacher's next writing
