| titleOfInvention | English teaching board |
| abstract | The utility model discloses an english teaching board, including base and teaching board, the teaching board is located the top of base and rotates rather than being connected, the cover is equipped with slidable C template on the teaching board, the upper and lower inner wall of C template all is equipped with the slide mechanism who offsets with the teaching board, the C template is equipped with the blackboard eraser with the one side that the teaching board is relative, be equipped with handle, negative-pressure air fan and dust collection box on the C template, two dust absorption pipes of the both sides fixedly connected with of C template, two the dust absorption pipe all is equipped with a plurality of dust absorption holes with the one side that the teaching board is relative, negative-pressure air fan's air inlet end is linked together through three-way pipe and two dust absorption pipes. The utility model discloses it is rational in infrastructure, produce the chalk end and absorb and collect when can cleaning the blackboard eraser, reduce the harm of chalk end to mr and student's health, the mr can once move clean chalk teaching board, and is efficient and convenient, the mr's that significantly reduces work load. |
