Abstract

The utility model discloses an electric blackboard eraser, wherein box grooves 2, 3 are respectively arranged on the upper edge and the lower edge of a blackboard 1, a blackboard eraser 4 is vertically arranged between the box grooves, an electric motor 5 is arranged on one side of the blackboard, wherein wire winding shaft 7, 8 are respectively arranged on the upper and lower ends of an extended rotating axis 6, pulleys 9, 10 are respectively arranged on the upper and lower ends of the other side of the blackboard, and draglines 11, 12 which are penetrated into an eyelet 13 on the two ends of the box grooves 2, 3 are fixed on the blackboard 4 through the pulleys 9, 10 and the wire winding shaft 7, 8. Due to the above mentioned technical proposal, the utility model needs not to use labor, but use electric power to erase the blackboard, and the height of the blackboard eraser is close to the width of the blackboard, thus the blackboard can be cleared by one time. The utility model not only saves time and labor, but also keeps clean and healthy.

Description

Electric blackboard eraser

Technical field

The utility model relates to a kind of blackboard eraser.

Background technology

Erasing the board now mostly to be to wipe with traditional small blackboard manually erases the board, and not only waste time and energy, and chalk dust flashes and four flies in the process that erases the board, and makes to be stained with dust on the person's of erasing the board coat-sleeve, and respiratory tract sucks dust, and is extremely unhygienic.

Summary of the invention

It is a kind of both time saving and energy saving that the purpose of this utility model is to provide, again the electric blackboard eraser of sanitation and hygiene.

Technical solution adopted in the utility model is, this electric blackboard eraser, top edge and lower limb at blackboard respectively are provided with a box groove, endways blackboard eraser that is provided with in it is provided with motor in a side of blackboard, and the two ends up and down of the turning cylinder of its prolongation are respectively equipped with the coiling wheel, opposite side at blackboard is respectively equipped with pulley in two ends up and down, stay cord passes the eyelet at box groove two ends, walks around pulley and coiling wheel, is fixed on the blackboard eraser.

Owing to taked technique scheme, so the utility model need not to use manpower again, but dependence electric power erases the board, and the height of blackboard eraser approaches the width of blackboard, once can wipe clean blackboard, and is both time saving and energy saving, again sanitation and hygiene.
