Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and is easy to use, and cost is cheap relatively, the blackboard eraser deduster that dust removing effects is desirable.
The purpose of this utility model is achieved in that a kind of electric blackboard eraser deduster, comprise box body, lid, dust percussing grating's plate, dust mouth are provided with a dividing plate, with the box space separated into two parts in the middle of box body, wherein be provided with a miniature motor in the part, one cam is housed on the main shaft of motor, and another part top is provided with dust percussing grating's plate, and the dividing plate top is equipped with fulcrum and is supported a vertical crank, crank one end is equipped with the blackboard eraser folder, and an end and cam are adjacent.
In order further to prevent flour dust overflow, can be provided with dust cover on box body top, dust cover is fixed on the box body upper edge, and dust cover is provided with opening, and perhaps dust cover is fixed on the frame, and framework is fixed on the casing by loose-leaf.
The dust mouth is positioned at the bottom of box body side, in order to remove place, dust dust mouth more easily drawer or the absorption dust device of collecting chalk dust can be set.
Motor is if vertically install, and can between the main shaft of motor and camshaft the intersecting axle travelling gear be installed, to guarantee that cam rotates up and down, can constantly touch to beat the crank head.
During use, open the lid, clamp the blackboard eraser frame with blackboard eraser, the lid that closes, actuating motor, the main shaft of motor drives cam and rotates, cam constantly clashes into crank one end, drives the crank other end and moves up and down, and causes blackboard eraser felt position constantly at dust percussing grating's plate bump, chalk dust falls at the bottom of the case in the drawer, thereby reaches the effect of dedusting.If have a power failure, can grasp blackboard eraser across dust cover, firmly on dust percussing grating's plate, impact, also can reach the effect of dedusting.
The beneficial effects of the utility model are; Simple in structure, easy to operate, electric and hand all can, can thoroughly remove and accumulate and stick to the inner and lip-deep chalk dust of blackboard eraser felt, and the phenomenon that no dust flies upward everywhere in dust removal process.
