Abstract
The utility model relates to a teaching tool, in particular to a dust absorbing blackboard eraser. The dust absorbing blackboard eraser comprises a blackboard eraser shell. An eraser plate is arranged on the lower portion of the blackboard eraser shell. A sponge or a nylon eraser body is arranged on the eraser plate. A plurality of irregular dust absorbing grooves are arranged on the eraser plate and the sponge or the nylon eraser body. The dust absorbing grooves are used for passing of the dust. A handle is arranged on the upper portion of the blackboard eraser shell. A battery is arranged in the handle. A cavity is arranged in the inner portion of the blackboard eraser shell. A motor is arranged in the cavity. A plurality of conductors are arranged on the periphery of the motor. The motor is connected with the battery in an electric mode. Electric currents are provided for the conductors by the battery. The dust absorbing blackboard eraser is controlled by the motor. Automatic degrees are high. A plurality of conductors are arranged on the periphery of the motor. Electric currents are provided for the conductors by the battery. The electric currents have good absorbing functions towards the dust. The dust produced in a blackboard mopping process is absorbed directly by the conductors. The dust is avoided to fly off.
