Description
Technical field
the present invention relates to teaching aid, particularly relate to a kind of suction and to erase the board the blackboard eraser of dust produced.
Background technology
when erasing the board, blackboard eraser and chalk dust friction can produce a large amount of floating dust, and these dust are unfavorable to human body, and the dust originally can recycled is wasted.
Summary of the invention
In order to overcome the deficiency of existing blackboard eraser, the present invention aims to provide a kind of blackboard eraser aspirating dust.
To achieve these goals, blackboard eraser of the present invention has such design feature:
A kind of blackboard eraser, comprises blackboard eraser and dust sucking device, it is characterized in that: described blackboard eraser two ends are provided with roller, and roller embeds in the guide rail of blackboard lower edges setting, and blackboard eraser top arranges dust sucking device; Described dust sucking device comprises puts ash cover, ash suction fan and motor, and ash suction fan is arranged on the dust-absorbing mouth place of putting ash cover and and is arranged on that to put the motor that ash covers between blackboard eraser coaxial.
Adopt above architectural feature, make the blackboard eraser of suction dust of the present invention, the dust produced is siphoned away in time and reclaims, be conducive to healthy when erasing the board.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of blackboard eraser embodiment of the present invention.
Fig. 2 is the structural representation of blackboard eraser embodiment of the present invention.
Detailed description of the invention
The description of symbols related in accompanying drawing: blackboard 1, guide rail 2, roller 3, blackboard eraser 4, puts ash cover 5, ash suction fan 6, motor 7, dust-absorbing mouth 8.
Below in conjunction with accompanying drawing, the structure of the blackboard eraser of the embodiment of the present invention and working method are described in detail.
As shown in Figure 1, a kind of blackboard eraser, comprises blackboard eraser 4 and dust sucking device, and described blackboard eraser 4 two ends are provided with roller 3, and roller 3 embeds in the guide rail 2 that on blackboard, 1 lower limb is arranged.
As shown in Figure 2, blackboard eraser 4 top arranges dust sucking device; Described dust sucking device comprises puts ash cover 5, ash suction fan 6 and motor 7, and ash suction fan 6 is arranged on dust-absorbing mouth 8 place of putting ash cover 5 and and is arranged on that to put the motor 7 that ash covers between 5 with blackboard eraser 4 coaxial.
When erasing the board, open motor 7 thus ash suction fan 6 and start working, promote blackboard eraser 4, roller 3 is along slide, put ash cover 5 to move with blackboard eraser 4, produce dust during letter written with chalk on blackboard eraser 4 blackboard wiping 1, dust sucks to put in ash cover 5 from dust-absorbing mouth 8 and recycles by ash suction fan 6.
The blackboard eraser aspirating the dust produced that erases the board of the present invention, has positive effect for keeping classroom environment health and avoiding dust to affect health.
