Abstract
The utility model discloses a dust absorption blackboard eraser. A micro-motor (3) is fixed inside an eraser body (1), the micro-motor (3) is in driving connection with fan blades (4); a cavernous block (5) is arranged inside the eraser body (1); the eraser body (1) is provided with a vent hole (6) and a dust absorption hole (7); the dust absorption hole (7), the micro-motor (3), the fan blades (4), the cavernous block (5) and the vent hole (6) are sequentially arranged from the brushes(2) to the back side of the eraser body (1). The fan blades run under the driving of the micro-motor, absorb dust from the dust absorption hole, and blow to the cavernous block, dust is absorbed by the cavernous block, and the gas is blown out of the vent hole, thus efficiently solving the problem of a plurality of dust caused by the prior blackboard eraser in use.
