Abstract
The utility model relates to a mechanical dust-removal blackboard eraser which is designed for solving the problem that the blackboard is required to be repeatedly cleaned during the teaching process, so that the pollution of the chalk dust to the classroom environment is very serious. The mechanical dust-removal blackboard eraser comprises a blackboard eraser casing (1), wherein a rotating wheel (3) is arranged in the blackboard eraser casing (1) and rotatably connected with a central shaft of a fixed blackboard eraser wheel brush (2); and a handle (4) and a dust-removal opening (5) are respectively arranged on the back side of the blackboard eraser casing (1). The utility model has the benefits that the mechanical dust-removal blackboard eraser has the characteristics of simple operation, less labor and little dust; and the rotating wheel drives the wheel brush to rotate during the blackboard cleaning process, the handwriting on the blackboard is erased under the action of the generated friction force, and not only the cleaning operation is labor-saving, but also a great part of dust is carried in the blackboard eraser casing, therefore, the degree of flying of the chalk dust is reduced, and the environment in the classroom is improved.
