Description
Technical field
The present invention relates to a kind of general burnisher, relate in particular to a kind of dust-free black board eraser that can the inspiration chalk dust.
Background technology
Existing common blackboard eraser is in the process that erases the board, chalk dust can constantly fall, and around blackboard, fly away and come, user and people on every side thereof are easy to suck chalk dust in this process, and influenced healthy, simultaneously a large amount of chalk dusts also be easy to be infected with to hand, on the face and on one's body, pollute.Through patent retrieval, the innovation and creation that our invention relates to blackboard eraser have over thousands of, yet these patents do not obtain enforcement or popularization, and the reason of searching to the bottom is the complex structure of good dedusting effect, the production cost height, simple in structure and dust removing effects that cost is low is relatively poor.
Summary of the invention
The object of the present invention is to provide a kind of dust-free black board eraser of simple in structure, easy to use, good dedusting effect.
Technical solution of the present invention is: a kind of dust-free black board eraser, and it comprises felt and box body, felt shape in a row evenly gummed is fixed on the face of box body; Be provided with dust-absorbing box, fan in the box body, the adjacent felt setting of dust-absorbing box, on the box wall between dust-absorbing box and the felt, in a row the gap location of felt evenly is provided with some through holes; Fan is arranged on the dust-absorbing box rear side, and the box wall between dust-absorbing box and the fan is provided with screen pack; It is characterized in that: also be provided with water box, laying dust box and switch in the described box body, the water box is arranged on the rear portion of dust-absorbing box, the top of fan, and water box and dust-absorbing box and total sidewall are provided with water fog generator, and the opening of water fog generator is in dust-absorbing box; The laying dust box is arranged on the below of dust-absorbing box, and communicates with dust-absorbing box, and the laying dust box can be extracted out in box body; Switch is arranged on the trailing flank of box body, and is connected with fan, water fog generator circuit.
Therefore the present invention has dust removing effects owing to use fan that chalk dust is sucked in the dust-absorbing box; Owing to set up water fog generator, atomized water spray in dust-absorbing box, so the quick moisture absorption precipitation of the dust in the dust-absorbing box make the interior dust concentration of dust-absorbing box maintain reduced levels, and dust removing effects is better; But the design of the pull of laying dust box is conveniently toppled over.The present invention has small and exquisite, easy to use, cost is low, pick-up performance is good advantage simple in structure.
