Abstract
The utility model relates to an electric dust adsorption blackboard eraser which comprises a blackboard eraser body (1); brush hairs (2) and a dust inlet (3) are formed under the blackboard eraser body (1); the dust inlet (3) is connected with a dust collecting bag (5) through a dust inlet pipeline (4); and an exhaust fan (6) is connected with the dust inlet pipeline (4) through a branch pipeline (7). The electric dust adsorption blackboard eraser has the advantage that when a blackboard is erased, as long as the exhaust fan is opened, the blackboard eraser moves and erases in one direction, and all chalk dust is adsorbed into the dust collecting bag, so that the environment in a classroom is greatly changed and is fresh without dust.
