It is distributed on the top of described wet gauze.
Further, the one side of described upper shell has to pick and place the removing mouth of wet gauze,
Being provided with clean out cover plate at described removing mouth, described clean out cover plate can be opened with described removing mouth
Close and connect.
This utility model compared with prior art, has the advantages that
On the one hand recyclable chalk powder, opotism can be good at preventing the chalk powder that wipes out everywhere
Fly away, on the other hand can strengthen the suction force of dust absorption fan, make absorption effect more preferable；Sheet bullet
The design of spring, during work, bristle hole is opened, it is thus possible to allow chalk bits pass through, during inoperative
Bristle bore closure, chalk bits cannot flow out；The design of pressure transducer, it is possible to pass through perception
Pressure during work controls the motor of dust absorption fan and starts and stop, and saves battery electric quantity, clearly
Design except mouth so that wet gauze is replaceable, can clear up, it is possible to reach the purpose recycled.
