A kind of dust-proof blackboard eraser, comprise housing, one end of housing is provided with handle, the other end of housing is provided with wiping board, the groove of wiping board surrounding hollow is provided with dust ring, the inwall of dust ring is provided with dust suction cloth, the bottom even of dust ring is distributed with the air suction opening being communicated with dust-absorbing fan, and dust-absorbing fan is communicated with the dust cabin of collecting dust.
Be flannelette in the material of dust suction cloth described in the utility model.
Further, the height of described wiping board is identical with the height of dust ring.
Further, described dust suction cloth and dust ring adopt detachable connection.
Further, the outer wall of described housing offers the switch controlling dust-absorbing fan.
Further, one end of described dust cabin is provided with the dust removal port concentrating cleaning dust.
The beneficial effects of the utility model are: this product structure is simple, is applicable in teaching environment, when wiping chalk, dust can effectively control by dust ring, avoid dust to dance in the air all over the sky, be conducive to the physical and mental health of student, and by dust-absorbing fan, unified for dust is adsorbed onto inside dust storehouse, concentrate and clear up, Practical Performance is excellent, and simple to operation, novel in design, be a kind of well innovation scheme, have very much marketing prospect.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model dust-absorbing fan structural representation.
100-housing in figure, 110-dust suction cloth, 120-wiping board, 130-air suction opening, 140-dust-absorbing fan, 150-dust cabin, 160-handle, 170-dust removal port.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See a kind of dust-proof blackboard eraser of Fig. 1, Fig. 2, comprise housing 100, one end of housing 100 is provided with handle 160, the other end of housing 100 is provided with wiping board 120, the groove of wiping board 120 surrounding hollow is provided with dust ring, the inwall of dust ring is provided with dust suction cloth 110, the bottom even of dust ring is distributed with the air suction opening 130 being communicated with dust-absorbing fan 140, and dust-absorbing fan 140 is communicated with the dust cabin 150 of collecting dust.
And the material of dust suction cloth 110 is flannelette.Better the dust of dust ring surrounding can be adsorbed, dust is avoided to fly to outside, the height of wiping board 120 is identical with the height of dust ring, guarantee in the process erased the board, dust goes to outside, and dust suction cloth 110 and dust ring adopt detachable connection, and dust suction cloth can accomplish effective cleaning, attract dust completely can be accomplished, the outer wall of housing 100 offers the switch controlling dust-absorbing fan.One end of dust cabin 150 is provided with the dust removal port 170 concentrating cleaning dust.
