Summary of the invention
In order to solve the technical problem of above-mentioned existence, the utility model provides a kind of blackboard eraser that can be adsorbed on blackboard that can absorb chalk dust.
For reaching above-mentioned purpose, a kind of blackboard eraser that can be adsorbed on blackboard of the utility model, comprise brush body, described brush body front end is provided with brush, described brush body rear end is provided with filter mantle, the dismountable connection brush body of described filter mantle, described brush body top is provided with magnet, cavity between described brush and filter mantle is built with a DC micromotor, described DC micromotor front end is connected with air draft fan leaf, described DC micromotor is fixed on the inwall of brush body, the side of described DC micromotor connects battery, the outside of described brush body is provided with a motor switch.
Further, a grey curtain of liftable screening is housed after described DC micromotor, along being provided with a lever on described screening ash curtain.
Further, be provided with a breach after described brush body, one end of described lever is stretched out from described indentation, there, and described balance pivot is arranged on described breach.
Further, the bottom of described brush body front portion is provided with a dustpan bucket, and described dustpan bucket is to brush top lopsidedness.
Further, the limit of described brush body front end surrounding is provided with moccasin.
Further, described brush comprises the framework that many spaced vertical bars are formed, and the front of described vertical bar is inlayed and arranged the first bristle, and the back side of described vertical bar is inlayed and arranged the second bristle, and described brush is connected with the dismountable clamping of described brush body.
Further, described filter mantle top and bottom are provided with dop, and described brush body rear end is provided with corresponding buckle, and the dop of described filter mantle is connected with the buckle clamping of brush body.
Further, described brush body bottom is provided with exhaust outlet, and described exhaust outlet is provided with detachable filter screen
The utility model achieves following technique effect:
DC micromotor drives air draft fan leaf, effectively can absorb the chalk dust of four ease when erasing the board in brush body; Upwards pull lever, hide grey curtain and be lowered, the dust savings be inhaled into is between the grey curtain of screening and filter mantle, when not using, pull lever downwards, hide grey curtain and be just lifted up, at this moment blackboard eraser can arbitrarily be placed, and dust can not be poured in the body of wall at motor place, more convenient; Scoop up mouth to be upturned, for containing chalk dust, moccasin can prevent from scratching blackboard; When quitting work, opening the exhaust outlet of brush body bottom, pouring out the dust that minority rests on brush body inside, often pulling down filter screen after a while, pour out dust, ensure that the wind path of dust absorption fan leaf is unimpeded.
Below in conjunction with accompanying drawing, the utility model is described in further detail.

Detailed description of the invention
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the utility model.
As shown in Figure 1, a kind of blackboard eraser that can be adsorbed on blackboard, comprise brush body 1, brush 2, battery 3 and filter mantle 4, cavity between brush 2 and filter mantle 4 is built with a DC micromotor 5, DC micromotor 5 is fixed on the inwall of brush body 1, battery 3 is fixed on the side of DC micromotor 5, the outside of brush body 1 is provided with a DC micromotor switch 14, DC micromotor 5 is equipped with an air draft fan leaf 6 above, pin the motor switch 14 of DC micromotor 5, start DC micromotor 5, air draft fan leaf 6 is driven to rotate, can dust be sucked in brush body 1, to reduce when erasing the board chalk dust to the harm of teacher or student's health.
DC micromotor 5 is equipped with a grey curtain 7 of liftable screening below, hide on grey curtain 7 along there being a lever 8, one end of lever 8 is stretched out from the indentation, there after brush body 1, lever 8 fulcrum is set on brush body 1 breach below, when using blackboard eraser, upwards pull lever 1, hide grey curtain 7 to be lowered, the dust savings be inhaled into, between the grey curtain 7 of screening and filter mantle 4, when not using, pulls lever 8 downwards, hide grey curtain 7 to be just lifted up, at this moment blackboard eraser can arbitrarily be placed, and dust can not enter in the cavity at motor 5 place, more convenient.
Filter mantle 4 be provided with dop up and down, with the corresponding buckle clamping of brush body rear end, bonnet can unload, the front end clamping of described brush 2 and brush body 1, the mobilizable dismounting of filter mantle 4, is beneficial to the dust clearing up savings, the front end clamping of brush 2 and brush body 1, easy disassembly.
