Abstract

The invention discloses an electrically-cleaned blackboard for teaching. The electrically-cleaned blackboard for teaching comprises a screw rod control box, wherein a blackboard body is arranged belowthe screw rod control box; a first fixed vertical plate is arranged at one side of the upper end in the screw rod control box; and a second fixed vertical plate is arranged at the other side relativeto the first fixed vertical plate, in the screw rod control box. The blackboard body is arranged at the bottom of the screw rod control box, and a sponge cleaning rod is driven to move on the blackboard body through a screw rod to eliminate words written with chalk, on the surface of the blackboard; and if further cleaning needs to be carried out, a micro water pump and a servo screw-rod motor can be started, a filter water inlet port is placed in a water bucket filled with water, and water is pumped into a water spray head and sprayed out to wet the blackboard, so that cleaning can be carried out during water spray, environment pollution due to flying of chalk dust in all directions, which is brought by manual wiping, is avoided, and then the body health of teachers and students is improved. The electrically-cleaned blackboard for teaching is simple and practical in structure, convenient to operate, and capable of greatly increasing the use efficiency.

Description

Technical field: [0001] The invention belongs to the technical field of educational equipment, in particular to an electric cleaning blackboard for teaching. Background technique: [0002] The blackboard is a common teaching tool, on which the teacher can write. After teaching, when the blackboard is full, it is necessary to wipe off the chalk on the blackboard before continuing to use it. The traditional blackboard does not wipe well when wiping the blackboard. It is clean, and all are wiped by hand, which greatly wastes teaching time, and the labor intensity is high. After a long time, the hands will become sore and soft, and the chalk dust will fly around when wiping the blackboard, polluting the environment. Too much chalk dust will affect the health of teachers and students. healthy. Invention content: [0003] The purpose of the present invention is to provide an electric cleaning blackboard for teaching in order to solve the above problems, which solves the current...
