Blackboard with electric brush

Abstract

The invention discloses a blackboard with an electric brush, which comprises a blackboard body, a brush body and a motor, wherein the brush body is movably arranged on the blackboard body; and the motor drives the brush body to move left and right on the blackboard body, thereby wiping off chalk characters on the blackboard body. The blackboard with the electric brush ensures that the chalk characters can be automatically wiped off because the motor drives the brush body to move left and right on the blackboard body, and a teacher can be free of wiping off the chalk characters. The teacher can be temporarily far away from the blackboard in a process of wiping off the chalk characters, thereby lightening the harm to the temperature by chalk dust, having a certain protection function to the teacher, and basically lowering the harm to the teacher by the chalk dust to the maximum.
