Further, described unsteady supporting mechanism comprises round brush bearing, electromagnet and rolling bearing, and described round brush bearing bottom is provided with armature, is provided with spring between described armature and the electromagnet, and described rolling bearing connects described electromagnet and is installed in the described horizontal slide rail.
Adopt the beneficial effect of above-mentioned further scheme to be, unsteady supporting mechanism can make the blackboard eraser device not need erase area not contact with blackboard, contacts and electric roller brush can be drawn onto with blackboard in the needs erase area, thereby wipes work.
Further, be provided with gauge tap in the described joystick, described gauge tap is used for control reducing motor and work of electromagnet.
Adopt the beneficial effect of above-mentioned further scheme to be, when the blackboard eraser device moves to when needing erase area, as long as press the gauge tap in the joystick, reducing motor and electromagnet are started simultaneously, even electric roller brush rotation work in the contact blackboard.
Further, the lower end of described dust cover also is provided with dust collection box, and the lower end of described roller brush shaft is provided with the dust suction fan blade, and the lower end of described dust collection box is provided with the cloth bag that gathers dust.
Adopt the beneficial effect of above-mentioned further scheme to be, dust suction fan blade and the cloth bag that gathers dust are installed in the lower end of roller brush shaft, can make the dust collection better effects if in the electric roller brush work operation of gathering dust simultaneously.The dust of collecting can also recycling.
Further, described top of going up horizontal slide rail also is provided with the flexible guide rod of lead.
Adopt the beneficial effect of above-mentioned further scheme to be, be convenient to the lead sliding extension of reducing motor and electromagnet.
Further, also be provided with the subregion groove on the described blackboard.
Adopt the beneficial effect of above-mentioned further scheme to be, at this blackboard, can write by subregion, be convenient to when wiping, accept or reject.
Further, a side of described dust cover also is provided with vertical chute, is provided with marking-off plate in described vertical chute, equidistantly is provided with the line spread pen on the described marking-off plate.
Adopt the beneficial effect of above-mentioned further scheme to be, drag the blackboard eraser device, utilize marking-off plate a plurality of parallel lines that can on blackboard, once draw, neat as conveniently writing, conveniently write foreign language and note line etc.Because marking-off plate can slide in described vertical chute, the horizontal line therefore can draw 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, can measure the distance of certain vertical direction on the blackboard easily, perhaps draw dimension line by means of rule.
