Four, description of drawings
Fig. 1 is a main pseudosection of the present utility model.
Fig. 2 is a left view of the present utility model.
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Provide by Fig. 1-2, the utility model comprises housing and motor, housing 1 internal upper part is equipped with battery 2, the motor 3 that is connected with battery is arranged at battery 2 bottoms, dust suction wet tissue 8 is housed in the housing 1, constitute dust discharge passage 13 between dust suction wet tissue 8 and motor 3 outer walls, fan blade 4 is housed on the motor shaft of motor 3, brush dish 5 is equipped with in fan blade 4 bottoms on motor shaft, between fan blade 4 and the brush dish 5 spring 6 is housed on motor shaft, brush coils 5 lower surfaces and places housing 1 outside, between brush dish 5 and the housing 1 suction port 12 is arranged, and there is switch 9 at the middle part on housing 1 lateral surface.
In order to guarantee result of use, said housing 1 is a hemispherical, and the handrail 11 that is connected as a single entity with housing 1 is arranged at housing 1 top, and the supply hub 10 that links to each other with motor 3 is arranged at the bottom, and battery cover 7 is arranged at the top.
Said battery 2 is the two joint rechargeable batteries of 1.5V, and motor 3 is that model is the direct current generator of 300C-14270.
The exhaust outlet that is connected with dust discharge passage 13 is arranged at said housing 1 top.
Operating position of the present utility model is, open motor 3, driven by motor fan blade 4 and brush dish 5 rotate, the dust that brush falls is under the effect of fan blade 4, be attracted on the dust suction wet tissue 8 through suction port 12, after brush coils the wearing and tearing of 5 parts, brush coils 5 lower surfaces still can place housing 1 outside under the effect of spring 6, can continue to use,, change the brush dish and get final product when brush dish 5 may wear to can not use the time, can reduce the use cost of blackboard eraser greatly, link to each other with transformer through supply hub 10, the utility model is directly external power supply use also, avoids the problem that can't use under the situation of dead battery.
The utility model structure uniqueness, easy to use, can effectively absorb the blackboard dust, greatly reduce the cost of blackboard eraser, have certain social and economic benefit.
