Abstract
An automatic dust wiping and suction device of a switching blackboard comprises a blackboard body, a transmission device and a wiping and suction rod. Guiding rails are arranged on two sides of the blackboard body, gear plates are arranged at two ends of the wiping and suction rod and rotate along the guiding rails, and the wiping and suction rod is a hollow rod with a dust suction cavity body. Brushes for wiping the blackboard are arranged on two adjacent outer side walls of the wiping and suction rod. Dust suction holes are arranged on the rod wall and connected with the hollow dust suction cavity body and brush bodies. One end of the wiping and suction rod is connected with the transmission device, an shaft wheel and a dust suction impeller are arranged on a rotating shaft of a micro motor of the transmission device from inside to outside, and the shaft wheel drives a transmission gear to drive the gear plates of the wiping and suction rod to rotate so as to enable the wiping and suction rod to move vertically. A dust collection box is arranged below the dust suction impeller. The automatic dust wiping and suction device of the switching blackboard can automatically wipe chalk handwritings on the blackboard and avoid damage of the dust to human bodies.
