Locate to be connected with the dust collection frame in blackboard brush shell.
Dust in the blackboard brush shell is collected frame and is communicated with ash output opening.
Dust in the blackboard brush shell collects the outside of frame the little air suction opening of a row.
The voltage of the electrostatic power set of the blackboard brush shell is 3 volts to 15 volts.
The blackboard brush housing exterior designs an Anti-slip cover or an expansion link.
The material of the blackboard eraser that the utility model is used is material that is soft and can adsorbing dust, can be corillas or hair
Felt.Power set of the present utility model can be powered by battery, it is also possible to design a small-sized electric energy storage device after charging
Use.Blackboard brush shell can be using the material such as rubber, wooden.
The beneficial effects of the utility model：
The utility model provides a kind of simple structure, uses, easy for installation, simple to operate, good new of dust removing effects
Electrostatic roll-type blackboard brush.When coming into operation, electrostatic power set are opened, start electrostatic generator, on manual erasing blackboard
Letter written with chalk, the dust around Electrostatic Absorption reduces injury of the chalk dust to Faculty and Students' body, it is to avoid dust floats everywhere
Dissipate, allow Faculty and Students to have a good teaching environment；After finishing, power supply is closed, jiggle blackboard eraser, dust is received
Dust in collection frame is pooled to ash output opening, opens ash output opening and collects dust, and dust can be uniformly processed, time saving and energy saving, at concentration
The dust of reason can be recycled again；Before input practicality, can first check that dust is collected with the presence or absence of dust in frame, will wherein
Dust collect after begin to use again.Electrostatic roll-type blackboard brush of the present utility model can be cleaned easily outside blackboard, and blackboard brush
The expansion link of shell can help the relatively short student of height, Anti-slip cover to prevent blackboard brush from dropping.It is of the present utility model not only to reduce
Dust and dust suction, use very environmentally friendly and health, and material is simple and easy to get, business application low cost, with very strong practicality.
