The invention discloses an environment-friendly blackboard preventing dust pollution. The environment-friendly blackboard preventing the dust pollution comprises a blackboard body and a motor. The upper portion of the blackboard body is fixedly connected with an electrostatic type eraser. The lower portion of the blackboard body is fixedly connected with a dust containing box. The electrostatic type eraser comprises a dust box. A rotating shaft is arranged in the dust box and connected with a piece of eraser cloth. One end of the eraser cloth is connected with the rotating shaft, and the other end of the eraser cloth is connected with a plastic plate. The eraser cloth is a piece of conductive cloth and electrically connected with an electrostatic generator. The rotating shaft is electrically connected with the motor. A touch-pressure switch is arranged on the plastic plate and is in signal connection with the electrostatic generator. According to the environment-friendly blackboard preventing the dust pollution, the physical character that an electrified body attracts tiny objects is utilized, and chalk dust is restrained from flying by controlling the electricity capacity of the eraser; and therefore, the physical health of teachers and students is effectively protected, and the teachers and the students are protected against dust hazards. The environment-friendly blackboard preventing the dust pollution is simple in structure and convenient to operate; and meanwhile, existing blackboards made from various materials can be refitted to be the environment-friendly blackboards preventing the dust pollution, and therefore application and popularization are benefited.
