erased the board from left to right, power wheel also drives Left Drive to take turns rotating forward while rotating forward and driving right drive to rotate forward, and Left Drive wheel rotates forward and drives left driven pulley to reversely rotate, but left driven pulley is subject to the impact of left single direction ratchet can only rotate forward and can not reverse, therefore, left driven pulley does not rotate, by chalkboard eraser from dextrad when erasing the board, power wheel reverses, drive right drive and the reversion of Left Drive wheel, can only reverse can not rotate forward because right drive affects by right single direction ratchet, therefore, right driven pulley non rotating, the reversion of Left Drive wheel drives left driven pulley to rotate forward, and left driven pulley rotates forward and drives mesomerism gear reversion, and mesomerism gear reversion drives left driving wheel to rotate forward, left driving wheel rotates forward flywheel driven reversion, and flywheel drives fan blade to rotate again and realizes dust suction, the position of the corresponding right driving wheel of equipment compartment and driving wheel is respectively equipped with right air outlet and left air outlet, right driving wheel enters outer casing space by right air outlet through equipment bulkhead, left driving wheel enters outer casing space through left air outlet, fan blade enters outer casing space through right air outlet and left air outlet after rotating the air-flow pressurization sucked, then is discharged to outside shell by venthole.
