Abstract

The invention discloses an automatic-wiping type teaching white board which comprises a mounting framework and a white board body. A mounting groove is formed in the front face of the mounting framework, and a left side mounting part and a right side mounting part are both internally provided with first electric telescopic rods. No side wall is arranged at the front end of an upper side mounting part, and the two ends of the upper side mounting part communicate with the left side mounting part and the right side mounting part. The upper ends of the two first electric telescopic rods are both provided with second electric telescopic rods perpendicular to the first electric telescopic rods. The front end face of the left side mounting part and the front end face of the right side mounting part are both provided with bar-shaped grooves allowing the first electric telescopic rods inside to stretch out of corresponding containing cavities. A fixed shaft fixed to the top ends of the two second electric telescopic rods is arranged between the two second electric telescopic rods. The fixed shaft is movably provided with a rotating drum, and the circumferential face of the rotating drum is provided with a white board eraser through a hook and loop fastener. Connecting blocks with clamping grooves are both arranged at the two ends of the rotating drum and located at the upper side and the lower side of the fixed shaft. Bar-shaped heating pieces clamped into the corresponding clamping grooves are installed above and below the rotating drum.

Description

technical field [0001] The invention relates to teaching tools, in particular to an automatic erasing type teaching whiteboard. Background technique [0002] At present, when teachers are teaching, they mainly use blackboard, chalk and blackboard eraser to cooperate with each other to realize writing. When writing chalk, there will be a lot of chalk dust, which will affect the health of teachers. The diameter and length of chalk are small, and teachers have labor intensity when writing. Big flaw; in addition, after writing, the blackboard needs to be manually cleaned by the classroom. If there are many blackboard writing required in the classroom, frequent cleaning of the blackboard will increase the burden of classroom teaching. It will be longer, and it is not conducive to the efficient use of time in the tense class atmosphere. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the automatic erasing teaching whiteboard provi...
