Description
Technical field
The utility model relates to a kind of teaching aid, is specifically related to a kind of electric dust absorption blackboard eraser.
Background technology
Blackboard is requisite the same teaching aid in the daily study of student, no matter from primary school or to university, blackboard is used in capital, with the essential blackboard eraser of blackboard, traditional blackboard eraser is made up of the hairbrush in a shell, shell, this blackboard eraser in use chalk dust flies upward everywhere, not only easy to use and have a strong impact on health and environmental sanitation.At present, existing many automatic blackboard erasers on market, but great majority are all fixedly mount for one piece of blackboard, volume is comparatively large, use inconvenience, and dust removing effects is poor, and installation and maintenance are complicated, and cost is higher.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of electric dust absorption blackboard eraser, volume is little, uses simple, can chalk writing on fast erase blackboard, and can collect dust efficiently.
Electric dust absorption blackboard eraser described in the utility model, comprise cuboid shell, shell one side is clean face, clean face is provided with Clean Brush for cleaning, relative another side is the back side, and enclosure is equipped with two identical rotatingcylindrical drums, and outer surface of cylinder cover has Clean Brush for cleaning, two cylinder one end are all connected with driven gear, and two driven gears engage a driving gear simultaneously; Shell rear surface is provided with air suction opening, disposal box is provided with outside shell rear surface, disposal box one end is provided with vavuum pump, the other end is provided with headstock, motor and power supply is provided with in headstock, motor input is connected by wire with power supply, and motor output end connects central shaft, and central shaft connects driving gear and vavuum pump successively.
Blackboard eraser shell is built with two cylinders, cylinder overcoat has Clean Brush for cleaning, when erasing the board, starter motor, driving gear and vavuum pump work simultaneously, and driving gear drives two cylinders to rotate, Clean Brush for cleaning on cylinder rotates clean blackboard surface, chalk dust is sucked disposal box from air suction opening by vavuum pump simultaneously, and disposal box can take off the dust removed the inside and pile up, and can take off cleaning or change after Clean Brush for cleaning uses a period of time.
Described air suction opening is distributed between two cylinders.
Four limits in described hull clean face are provided with rubber, and face of cleaning during use is pressed on blackboard surface, and when the rubber of clean face surrounding can prevent clean, the dust of Clean Brush for cleaning annex flies away housing exterior.
Described headstock is provided with power interface, when not using and chargeable.
Be equipped with finger indentations outside described disposal box He outside headstock, finger indentations is convenient by holding in use.
The beneficial effect that the utility model is compared with prior art had is:
Electric dust absorption blackboard eraser volume is little, uses simple, can chalk writing on fast erase blackboard, and the Clean Brush for cleaning in blackboard eraser and disposal box cleaning for convenience detach, adopt vavuum pump dust suction, dust suction power is sufficient, effective.
