Mobile blackboard wiping in target wiped area, main control chip sends out control signal and gives blackboard eraser folding and unfolding after the wiping of completion target area
The electromagnetic coil energization of adjustment mechanism generates electromagnetic attraction and overcomes the spring force of holddown spring to make blackboard eraser mutually be taken off with blackboard
From.
