Power transmission shaft is connected with fan shaft, power transmission shaft overcoat one hollow axle, and hollow axle is connected with rubbing head rotating shaft and train of reduction gears respectively.
Described disc rubbing head and the fan blade of blower fan, axial location is off, and machine shaft is connected with fan shaft, electricity
Machine rotating shaft connects power transmission shaft by train of reduction gears again, and power transmission shaft is connected with rubbing head rotating shaft.
Uniformly being provided with several safety contact switch on the peripheral plane of described disc rubbing head, shape and circuit board are driven in contact
Connecting, only when several safety contacts switch all presses onboard, motor power is just connected.
In described housing outside the circumference of impeller of blower, noise reduction ring is installed.
Described wiper blade has multi-disc to be uniformly contained in rubbing head, and wiper blade is circular, or triangle.
The beneficial effects of the utility model are, the electric blackboard eraser designed by this utility model achieves technically with one
Individual motor realizes the dual-use function of wiping and dust suction, had both improve the work efficiency of electric blackboard eraser, and had reduced again the weight of self
Amount, it is most important that the structure design that this utility model is given is simple, easily implements.
This utility model devises silencing means, can greatly reduce the noise that dust absorption fan produces.
Electronic rubbing head of the present utility model, can change, if rubbing head abrasion, then changes rubbing head, it is not necessary to whole electronic black
Blackboard eraser is discarded, and has the strongest practicality.
The blackboard wiping that is mainly used for of the present utility model, but if changing wiping head, may be used for multiple use.As,
If wiping head is changed into brush form, it is also possible to the dust on wiping wall.
This utility model have also been devised safety guard, only all presses close to blackboard when the contact switch that rubbing head is peripheral
Face, electric blackboard eraser just can be started working, and to guarantee the personal safety of operator, enhances practicality.
This utility model is equipped with the polymer battery/super capacitor of high-energy-density, it is possible to achieve instant fill, it is not necessary to
Plug battery, convenient and swift.
