Adopt the beneficial effect of above-mentioned further scheme to be, Floatable supporting mechanism can make board wiping device not contact with blackboard not needing erase area, and electric roller brush can be drawn onto in needs erase area and contact with blackboard, thus carries out erasing work.
Further, be provided with gauge tap in described joystick, described gauge tap is for controlling reducing motor and work of electromagnet.
Adopt the beneficial effect of above-mentioned further scheme to be, when board wiping device move to need erase area time, as long as press the gauge tap in joystick, reducing motor and electromagnet can be made to start, even if electric roller brush rotation work while contact blackboard simultaneously.
Further, the lower end of described dust cover is also provided with dust collection box, and the lower end of described roller brush shaft is provided with dust suction fan blade, and the lower end of described dust collection box is provided with the cloth bag that gathers dust.
The beneficial effect of above-mentioned further scheme is adopted to be in the lower end of roller brush shaft, dust suction fan blade and the cloth bag that gathers dust are installed, can carry out gathering dust operation in electric roller brush work simultaneously, make dust collection better effects if.The dust collected can also recycling.
Further, the top of described upper horizontal slide rail is also provided with wire and stretches guide rod.
The beneficial effect of above-mentioned further scheme is adopted to be convenient to the wire sliding extension of reducing motor and electromagnet.
Further, described blackboard is also provided with subregion groove.
Adopting the beneficial effect of above-mentioned further scheme to be, for this blackboard, can write by subregion, being convenient to accept or reject when wiping.
Further, the side of described dust cover is also provided with vertical chute, is provided with marking-off plate, described marking-off plate is equidistantly provided with rowed brush for marking in described vertical chute.
The beneficial effect of above-mentioned further scheme is adopted to be drag board wiping device, utilize marking-off plate can once draw multiple parallel lines on blackboard, as neat in conveniently write, conveniently write foreign language and note line etc.Because marking-off plate can slide in described vertical chute, therefore horizontal line can be drawn in the optional position of blackboard.
Further, the opposite side of described dust cover is provided with rule.
Adopt the beneficial effect of above-mentioned further scheme to be to measure the distance of certain vertical direction on blackboard easily, or draw dimension line by means of rule.
