Description
Technical field
Realia field is the utility model is related to, particularly relates to a kind of electrostatic dust prevention blackboard eraser.
Background technology
Blackboard eraser is instrument essential in classroom, and people are erased the board by blackboard eraser, but now in classroom
Blackboard eraser has the shortcomings that certain, and user's chalk dust when erasing the board is more, the student near from blackboard can be caused uncomfortable, in teaching
When wiping letter written with chalk, caused chalk dust is flown upward the ordinary blackboard eraser used everywhere, not only influences the cleaning of classroom human body
Health, and the health of teachers and students is influenceed, bring puzzlement to Students ' Learning teachers ' teaching.
Utility model content
The utility model proposes a kind of electrostatic dust prevention blackboard eraser, solve in the prior art that chalk bits are flown upward, influence classroom
Air quality, the problem of endangering Faculty and Students' health.
What the technical solution of the utility model was realized in：
A kind of electrostatic dust prevention blackboard eraser, including spongy layer, include fixed plate, collecting plate and the power of fixed spongy layer
Plate, the power plate, collecting plate, fixed plate and spongy layer are set gradually；The fixed plate is provided with through hole, and spongy layer passes through logical
Hole is fixed in fixed plate, and several ion wind rods are provided between fixed plate and collecting plate（ELIMINOSTAT CABX）, ion
Wind rod one end is fixed on collecting plate, and the other end connects with fixed plate；The collecting plate plate face is provided with latticed metal wire
Circle；Air exhauster and power supply are embedded with the power plate.
The dust-proof blackboard eraser is additionally provided with detachable shell, and power plate, collecting plate and fixed plate are rolled into one by shell
It is overall.
Beneficial effect caused by the technical program energy：Electrostatic dust prevention blackboard eraser of the present utility model, collecting plate mesh-type
Wire coil the colelctor electrode of a positively charged is formed in the case where switching on power, ion wind rod is connected with collecting plate, sea
The dust adhered on continuous layer takes negative electrical charge in the presence of ion wind rod, the dust with negative electrical charge and the collection with positive charge
Dirt plate mutually attracts, and also by dust to assembling on collecting plate under the drive of power supply, dust is attached on collecting plate air exhauster.This reality
With new disclosed electrostatic dust prevention wiping blackboard structure novelty, good dustproof effect, solve chalk bits and fly upward, influence Classroom air matter
Amount, the problem of endangering Faculty and Students' health.
