The invention discloses a dustless electric blackboard. The dustless electric blackboard comprises a
machine body, and a first cavity formed in the
machine body; a second cavity is arranged above thefirst cavity; a first rotating shaft, extending left and right, is arranged in the first cavity; the
tail end of the right side of the first rotating shaft is in power connection with a motor slidingly arranged in the right side end wall of the first cavity; a first
bevel gear is fixedly arranged at the
tail end of the left side of the first rotating shaft; and a second rotating shaft, extending up and down, is rotationally arranged between the first cavity and the second cavity. The equipment is simple in structure, uses an
electric energy driving mechanical structure for realizing automaticswitching of the blackboard as needed, realizes automatic wiping without needing manual operation, and meanwhile, uses a
centrifugal pump for extracting dust generated in wiping of the blackboard to prevent the influence on the health of
teaching staff and students by a lot of dust; and through switching of two blackboards, the effective writing area of the
teaching staff is guaranteed, and meanwhile, the
automation degree and the practicability of the equipment are improved.
