As a kind of preferred version, on front side of blackboard body, lower end arranges the length water leg corresponding to blackboard body length, and water leg one end arranges discharge outlet, and discharge outlet connects the import of supply tank by water pipe.
As another kind of preferred version, between the import and water pump of described supply tank, be provided with screen pack.The water collected in water leg, after filtration after net filtration, is again sent in pipeline through water pump and is used, water reuse saving resource.
As another preferred version, described air intake device is dust catcher.
The beneficial effects of the utility model
1, wiping efficiency is high
Blackboard eraser described in the utility model is strip blackboard eraser, only need push to opposite side from side and can complete a wiping process during use, for ensureing that wiped clean can repeated multiple times wiping.Pushing is once the whole blackboard panel of erasable, and efficiency is very high.
2, dust from flying can be avoided
Slip blackboard eraser described in the utility model comprises the soft bristle that the hollow seated tube and hollow seated tube vertically placed are arranged; Described hollow seated tube side is provided with air inlet, and described hollow seated tube one end is connected with induced-draught fan by flexible pipe.Opening induced-draught fan in wiping process sucks in induced-draught fan by the air inlet of hollow seated tube by dust, reduces dust in air amount.In addition, the utility model blackboard body upper end is provided with pipeline, and lower end of duct is provided with faucet, and pipeline connects water supply installation by water pipe.After wiping by water pump to pipeline inner water-supply, water sprays from faucet to blackboard panel.Make dust flow in water leg with water, reduce dust further.
