Cleaning device for blackboard eraser

Abstract

The invention discloses a cleaning device for a blackboard eraser. By arranging the cleaning device and arranging a plastic brush on the outer side of the cleaning device, when a motor drives the cleaning device to rotate, the plastic brush on the outer side can sweep down chalk dust on a brush of the blackboard eraser, and a cleaning chamber is in the closed state, so that the situation that dust is diffused and consequentially people inhale a large quantity of the chalk dust is avoided, and the health of people is facilitated. By arranging the blackboard eraser in an arc shape and arranging a connection rod on the back face of a shell of the blackboard eraser, the connection rod can be fixed into a threaded hole in the cleaning device, and thus the situation the blackboard eraser is prone to being thrown away due to infirm fastening when the blackboard eraser rotates at a high speed is avoided. By additionally arranging a water tank above the cleaning chamber and using a nozzle for spraying water onto the blackboard eraser, the cleanliness of the blackboard eraser is convenient to improve. By arranging a drying chamber, when the blackboard eraser is sprayed and washed with water, the blackboard eraser can be placed into the drying chamber and rapidly dried by starting an electric heating plate and a fan, and teachers use the blackboard eraser without being affected.
