Abstract
The utility model discloses a large-area electric blackboard eraser which comprises an eraser brush, a brush casing, a motor, a double-throw switch, an upper pulley, a lower pulley and a frame. The eraser brush is embedded in the brush casing; the upper end of the brush casing is connected with the upper pulley; the lower end of the brush casing is joined with the lower pulley; and the upper pulley is directly connected with a rotating shaft of the motor; and the upper pulley, the motor and the double-throw switch are arranged on and connected with the frame to form a whole body. The blackboard eraser is switched on when in use, if the right key of the double-throw switch is pressed, the motor rotates clockwise to push the upper pulley and drive the lower pulley, and the brush casing and the eraser brush are forced to do translational cleaning from left to right; and contrarily, the motor rotates counter-clockwise, and the eraser brush does cleaning from right to left. The blackboard eraser has the characteristics of reasonable design, simple structure, convenient operation, effective cleaning and the like.
Description
Technical field
The utility model relates to a kind of blackboard eraser, particularly a kind of large tracts of land electric blackboard eraser.
Background technology
Nowadays, be widely used in the blackboard eraser of teaching, though can effectively wipe the dust on the blackboard, it is little that it wipes scope, and dust from flying, and this is that people expect the problem that solves.
The utility model content
The purpose of this utility model just is to overcome the deficiency of prior art, and a kind of large tracts of land electric blackboard eraser reasonable in design, easy to use is provided.
In order to achieve the above object, the technical solution adopted in the utility model is:
The large tracts of land electric blackboard eraser comprises: brushing, brush shell, motor, two switch, top sheave, lower sheave and framework put is characterized in that:
Described brushing is nested in the brush shell, and brush shell upper end is connected mutually with top sheave, and brush shell lower end is connected mutually with lower sheave, and top sheave directly is connected with machine shaft again, is arranged on the framework together with two switches of putting, and combines to constitute an integral body.
During use, connect power supply, if press two switch right buttons of putting, the rotation of motor up time promotes top sheave, drives lower sheave, forces brush shell and brushing translation wiping from left to right; Otherwise, the rotation of motor inverse time, brushing is wiping from right to left.Have characteristics such as reasonable in design, simple in structure, easy to operate, that wiping is effective.
