A kind of dust-sucking eraser comprises box body, is provided with capping in a side of box body, is provided with some bundle hairbrush in the outside of capping, offers several air suction openings in capping, is provided with the dust exhaust apparatus that is communicated with air suction opening in box body.
Below be the utility model for further improvement of these options:
Described dust exhaust apparatus comprises the dust sucting motor that is arranged in the box body, is provided with the sweep-up pipe that is communicated with air suction opening on dust sucting motor.
Further improve:
Be provided with dividing plate sealing together at box body, form the dust suction storehouse between sealing dividing plate and the capping, described dust sucting motor is communicated with the dust suction storehouse by sweep-up pipe.
Described dust sucting motor is arranged on the opposite side of seal diaphragm.
Further improve:
Be provided with dust-collecting box near a side of dust sucting motor in box body, described dust-collecting box is communicated with by communicating pipe with dust sucting motor, has the dedusting opening on the described dust-collecting box, and this dedusting opening is opened on the shell wall of box body and uses rubber stopper seal.
The outside at box body is equipped with switch, and described dust sucting motor is electrically connected with switch.
The utility model adopts such scheme, when erasing the board, as long as open switch earlier, erases the board at every turn again, just can avoid dust inspiration dust-collecting box dust disorderly to fly.After using up, again rubber stopper is opened at every turn, dust is outwelled got final product, convenient easy-to-use, avoided dust disorderly to fly, protected environment, make the people in academic environment, healthy more.
