The utility model is by arranging a spring, after can making the wiping of blackboard eraser removal apparatus complete, automatically reset, very convenient, and by the aspiration of negative pressure unit and sealing strip are set, can effectively prevent that chalk dust bits from leaking outside causes flying upward, and very reasonably chalk dust bits is collected, and prevents contaminated environment.
Further, as preferably, in order to improve the effect of wiping to blackboard, the erase unit of described erasing apparatus is cylinder shape hairbrush, and is two of be arrangeding in parallel.
Further, in order preferably to be inhaled dust collection effect, as much as possible chalk dust bits are absorbed completely, described the aspiration of negative pressure unit is the funnelform suction inlet of rectangle, and is arranged between the cylinder shape hairbrush described in two.
Further, as preferably, for make erasing apparatus on the first track and the second track smoothly, move freely, the first described track and the second described track are tooth bar, the mobile unit of described erasing apparatus is the gear matching with described tooth bar.
Further, as preferably, in order to prevent that chalk dust bits from leaking outside and causing flying upward in erasing apparatus erase process, described sealing strip is arranged on described wiping arrangement and the surrounding of blackboard contact-making surface, and the surface of described edge band exceeds the highest surface of the cylinder shape hairbrush of described erasing apparatus.
Further, in order further to improve and improve the effect of wiping of erase unit, and automatically to realize be once erasable clean object, the utility model also comprises two motors, the cylinder shape hairbrush that motor described in two is respectively described in two provides the power of rotation, and the cylinder shape hairbrush described in two is rotated towards described the aspiration of negative pressure cell orientation.
Further, as preferably, described shell is rectangle shell.
The beneficial effects of the utility model:
1, the utility model, by a spring is set, after can making the wiping of blackboard eraser removal apparatus complete, automatically resets, very convenient, the time that can effectively save erasing blackboard, raise the efficiency, and reduce labour;
2, simultaneously, the utility model is by arranging the aspiration of negative pressure unit and sealing strip, can effectively prevent from that chalk dust bits from leaking outside to cause flying upward, and very reasonably chalk dust bits collected, and prevents contaminated environment;
3, this use is novel by the movement of wheel and rack is set, and can realize very free, flexibly the movement of erasing apparatus, and then realize wiping of each position of blackboard.
