Abstract
An electric blackboard eraser is designed aiming at solving the problems that dust is heavy, environment is polluted, and the health of both teachers and students is influenced which exist in current blackboard erasers. The electric blackboard eraser comprises a blackboard eraser shell body, a handle, and a switch arranged on the handle. A motor is arranged in the blackboard eraser shell body and near the center of the blackboard eraser shell body, an erasing plate is arranged on a vertical downward output shaft of the motor, and the size of the erasing plate is matched with the size of an opening in the bottom of the blackboard eraser shell body. A vacuum cleaner and a rechargeable battery are respectively fixed on both sides of the blackboard eraser shell body. Holes are distributed in the erasing plate, and the holes are communicated with a dust storage chamber in the blackboard eraser shell body through the vacuum cleaner. The electric blackboard eraser has the advantages of being convenient to use and install. To clean a blackboard, a user does not need to wipe repeatedly, the dust on the blackboard can be absorbed without leakage, so the wiping is easy and the vacuum cleaning effect is good. The electric blackboard eraser can be used repeatedly by charging the battery.
