The specific embodiment
In the utility model, shown in Fig. 1 to 10, when erasing the board with diagonal flow type electric dust absorption blackboard brush, press power switch button (9), connect power supply, high speed direct current generator (21) drives diagonal flow type screw (22) high speed rotating, make inlet plenum (36) produce negative pressure, and dust compartment (11) produces malleation, brush body (1) is by suction hole (32) like this, and the dust when erasing the board under the brush sucks rapidly, when the air-flow that contains dust enters dust compartment (11), laid the dust slanting baffle (10) and the baffle plate that lays the dust (12) stops, behind the flow-disturbing, be detained the lower part dust, the filter screen (29) that passes through again on the filter (3) filters, the air of cleaning is discharged brush body, thereby reach the purpose of dedusting.When the more dust of dust compartment (11) storage, can open filter (3), to topple over and dust, behind the cleaning filter screen, closing gets final product again.When rechargeable battery (24) when not having electricity, by charge switch (7), connect charger, be full of electricity after, just can reuse.If brush cotton (6) consume is more for a long time, only need press and change brush switch (16), scratch the separation button (35) on the moving cloth-cleaning baffle, change new cloth-cleaning baffle (4) and get final product.
The utility model compared with prior art, mainly be to have adopted the design of diagonal flow type propeller, it is smaller and more exquisite to make that brush body can design, because in the Design of Propeller of equal specification, the diagonal flow type screw can produce the pressure that more strengthens than Axial-Flow Propeller, the wind-force that the ratio centrifugal screw is bigger.Simultaneously brush body is according to actual conditions, according to ergonomics principle and people's use habit design, makes in that to grip diagonal flow type electric dust absorption blackboard brush more easily comfortable when using.
