It is segmented into water storage case and rub body mounting box；Numerous said minuscule holes are provided in the partition；
Water injection hole is provided on the water storage case；
Groove in rub body mounting box is for installing rub body；A box cover, the box cover are provided on the rub body mounting box
It is fastened on rub body mounting box by hasp；
The blackboard eraser two sides are respectively arranged with slide opening, and first litter and the second litter are set in blackboard eraser two
In the slide opening of side；
Second litter top is provided with a fixed pulley, and the wirerope connects after fixed pulley through blackboard eraser and shaking tray
It connects, the blackboard eraser is fixed on wirerope.
Further, the rub body is made of flexible foam or sponge material.
Further, it is placed with sponge in the water storage case water storage case of the bottom plate, passes through partition Small Holes to slow down water flow
The speed in hole.
Further, the diameter of the said minuscule hole is less than 1 millimeter.
The beneficial effect of technical solution described in the utility model is：The left and right of blackboard eraser is realized by litter and track
It is mobile, it drives blackboard eraser to move up and down by shaking tray, facilitates the inconvenience of personnel's erasing blackboard of short and small stature；By in blackboard eraser
Upper setting water storage case, and penetrate into the water in water storage case slowly on rub body, it can effectively reduce what erasing blackboard generated in the process
Dust maintains health；By the way that lid, the convenient rub body replaced in blackboard eraser at any time is arranged in blackboard eraser；The present apparatus
Simple and stable structure is good, so that its cost is lower and easy to maintain；The present apparatus does not need consumption electric energy in use,
