Aiming at the deficiencies in the prior art above, the purpose of this utility model is to provide an electric dust-absorbing blackboard eraser.

In order to achieve the above object, the technical solution adopted by the utility model is: an electric dust-absorbing blackboard eraser, including a blackboard eraser body, a motor, a hair sticking seat, a dust suction fan, a dust storage room and a power supply device; the blackboard eraser A power supply device and a motor are installed on the left side of the main body, and a rotating shaft is installed on the output shaft of the motor, and a dust suction fan is arranged in the inner cavity of the blackboard eraser body, and the dust suction fan is sleeved on the rotating shaft, and one end of the rotating shaft is installed on the On the sticky base, the fan face is facing the bottom of the blackboard eraser body, the dust suction fan is electrically connected to the power supply device through a switch, and the switch is installed on the upper end of the blackboard eraser body, and a filter is provided between the dust suction fan and the sticky base. Net, filter screen and blackboard eraser body right side form dust holding room, dust holding room lower end is provided with dust outlet, and the bottom near left side of described blackboard erasing body is provided with air outlet.

Further, a handle is installed on the left side of the blackboard eraser body.

Further, the sticky wool seat is provided with dust suction holes and sticky wool.

Further, a charging jack is provided on the left side of the power supply device.

After adopting above-mentioned technical scheme, the advantage that the present utility model has compared with prior art is:

In the electric dust-absorbing blackboard eraser described in the utility model, the switch is pushed, the circuit is closed, the dust-absorbing fan works, the dust enters the inner cavity of the blackboard eraser body from the dust-absorbing hole, and due to the blocking effect of the filter, the dust gathers in the dust-holding chamber; Reduce the flying of dust and ensure the health of teachers and students. With the handle, you can easily hold the blackboard eraser, and by installing one end of the rotating shaft on the sticky seat, when the power is turned on, it can drive the sticky seat to rotate, no need Artificial repeated wiping reduces the workload of teachers.
