The automatic dust suction blackboard eraser can automatically and speedily absorb the chalk dust into the dust collecting bag of the blackboard eraser which cleans the air, protects health with safe use and is an indispensable teaching beneficial instrument.
Description
Technical field
The utility model relates to a kind of teaching used tool automatic dust absorption formula blackboard eraser.
Background technology
At present, the used blackboard eraser of school mostly is to encase thick wool felt with iron sheet to make.In wiping process, chalk dust disorderly flies everywhere, and this is the main cause that causes occupational diseases such as teacher's tuberculosis, and this type of blackboard eraser usefulness long afterwards, and chalk dust is trapped in the wool felt for a long time, causes wool felt to harden, become dead, influence is normal to be used, and wiping was both required great effort, and effect is relatively poor again.
Summary of the invention
It is a kind of simple in structure, easy to use that the utility model provides, and the chalk dust under wiping can be sucked the automatic dust absorption formula blackboard eraser that carries out isolated by filtration in the blackboard eraser automatically.
The technical scheme that its technical problem that solves the utility model adopts is: adhere in the rub body of interlayer sheet another side of wiper and be provided with the dust exhaust apparatus of being made up of power supply, micromachine, button, fan, wind-collecting cover, dust bag, the coaxial connection of fan of the micromachine of dust exhaust apparatus and wind-collecting cover cover neck back, be with dust bag on the dust-exhausting port below the fan.By power supply control minitype motor driving fan high speed rotary, form negative pressure, dust laden air all gathers in the dust bag behind wiper, netted interlayer sheet, wind-collecting cover during with wiping, through the dust bag isolated by filtration, dust-free air is discharged from outside the bag, and dust is collected in the dust bag.
The beneficial effects of the utility model are: can fast chalk dust be sucked in the dust bag of blackboard eraser automatically, purify air, protect the health, safe in utilization, useful educational aid is absolutely necessary.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1, wiper 1, interlayer sheet 2, rub body 3, wind-collecting cover 4, fan 5, power supply 6, motor 7, button 8, dust bag 9, handle 10, dust-exhausting port 11.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 1, adhere in the rub body 3 of interlayer sheet 2 another sides of wiper 1 and be provided with the dust exhaust apparatus of forming by wind-collecting cover 4, fan 5, power supply (battery) 6, micromachine 7, button 8, dust bag 9.When using this blackboard eraser, hold handle 10, thumb is pinned button 8, and power supply 6 is opened, and drives micromachine 7 high speed rotaries, with the coaxial fan 5 of motor 7 also high speed rotary thereupon, form negative pressure in the rub body 3, the air that contains chalk dust during wiping sucks in the dust bag 9, again through dust bag 9 isolated by filtration behind wiper 1, netted interlayer sheet 2, wind-collecting cover 4 fast, dust-free air is discharged from outside the dust bag 9, and dust is collected in the dust bag 9.After wiping finishes, unclamp knob 8, power supply 6 cuts off, and motor 7 shuts down.But dust bag 9 regular dismounting that are with on the dust-exhausting port 11 below the fan 5 are cleaned or are changed.
