Abstract
The utility model discloses a novel dustproof blackboard eraser. The novel dustproof blackboard eraser comprises a hollow brush cover, wherein the hollow brush cover is formed by an upper cover body and a lower cover body being connected in a detached mode, the upper surface of the upper cover body is a flat face, multiple rows of strip-shaped holes which are parallel to one another are formed in the flat face, brush hairs are connected inside the strip-shaped holes in a detachable mode, and air holes are formed among the strip-shaped holes, and a dust exhaust device is arranged inside the brush cover. Besides, the dust exhaust device comprises a dust collecting bag, a draught fan, a battery, and a switch, wherein the draught fan is arranged on a bag opening of the dust collecting bag, the battery supplies power for the draught fan, and the switch is used for controlling work of the draught fan. The draught fan comprises a wind feeding face and a wind blowing face, wherein the wind feeding face faces towards the air holes. The strip-shaped holes are parallel to one another, the brush hairs are enabled to be parallel, the air holes are formed among the strip-shaped holes, after the brush hairs are connected inside the strip-shaped holes in the detachable mode, and gaps are reserved among the brush hairs. When a person erases a blackboard, dust can enter the air holes through gaps among the brush hairs, and the dust exhaust device is arranged inside the brush cover, and therefore the dust exhaust device can absorb dust through the air holes.
