Abstract

A blackboard with an electric blackboard eraser is characterized in that the blackboard eraser is arranged on the upper portion of a blackboard surface, is controlled by a motor, and is limited by a blackboard eraser fixing groove to move vertically by clinging to the blackboard surface; the length of the blackboard eraser is the same with that of the blackboard; and the height of the blackboard eraser fixing groove is the same with that of the blackboard. Compared with the existing blackboard, the blackboard with the electric blackboard eraser has the advantages that the automatic blackboard eraser is arranged on the blackboard, and is controlled by the motor; the time of teachers can be saved when the automatic blackboard eraser is used for erasing the blackboard; and the classroom teaching efficiency is improved.

Description

technical field [0001] The invention relates to a blackboard with an electric blackboard brush, which belongs to the field of teaching tools. Background technique [0002] The blackboards used in classrooms at this stage, especially the blackboards in large lecture halls, because of their relatively large blackboard area, only rely on the original blackboard brush to clean the blackboard, which is time-consuming and laborious, which will increase the workload of teachers. Reduce teaching efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a blackboard with electric blackboard brush, so as to overcome the low efficiency of the original blackboard brush at the present stage. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A blackboard with its own electric blackboard brush is characterized in that a blackboard brush is arra...
