Abstract
The utility model discloses a chalk-dust suppression blackboard eraser, comprising a blackboard eraser body. The dust-suppression blackboard eraser is characterized in that the a chalk-dust collecting box; the first edge of the chalk-dust collecting box is connected with the handle of the blackboard eraser body, and the second edge which is half the length of the first edge is provided with a soft cover contacting with the blackboard eraser body; and the soft cover is in a smooth curve structure. With the technical scheme, when the chalk-dust suppression blackboard eraser is used for erasing the blackboard, the generated chalk dust can fall into the chalk-dust collecting box along the soft cover in the smooth curve structure, thus the chalk dust is reduced. After the chalk-dust suppression blackboard eraser is used for a period of time, the chalk-dust collecting box can be detached to be cleaned for further use.
Description
Technical field
The utility model relates to a kind of blackboard eraser, particularly a kind of dust suppression blackboard eraser.
