Embodiment Construction

[0010] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes a blackboard eraser 1, which is characterized in that: the handle of the blackboard eraser 1 is a cavity 2 filled with water, and the cavity 2 is provided with a water seepage hole 3 on the side wall corresponding to the brush of the blackboard eraser 1; The other side wall of the cavity 2 is provided with a water injection hole 5 plugged with a plug 4 .

[0011] Adopt the water seepage blackboard eraser of the present invention, when using the blackboard eraser 1 to wipe the blackboard, the water in the inner chamber 2 passes through the water seepage hole 3 to the brush of the blackboard eraser 1, so that the blackboard eraser 1 does not have chalk foam flying around. If the water in the inner cavity 2 is used up, the plug 4 can be opened to inject water from the water injection hole 5.
