A hairbrush is arranged at the side of the blackboard body, which is used for cleaning chalk powder left in a lower border of the blackboard. As a water inlet pore communicated with a cavity is arranged at one side with the mirror of the blackboard eraser body and a water outlet pore communicated with the cavity is arranged at one side with the erasing yarns of the blackboard eraser body, when cleaning the blackboard eraser, water flows from the water inlet pore to the cavity and then out of the water outlet pore to clean the erasing yarns. The blackboard eraser has the advantages of simple structure, various functions and convenient use.
