Description
Technical field
The utility model relates to a kind of teaching aid, is specifically related to a kind of wet type dust-proof blackboard eraser.
Background technology
In daily teaching, blackboard is indispensable teaching aid, and last class hour teacher can erase the board frequently, and the student on duty classmate also will erase the board in the time of after class, and chalk powder is sucked in the lung by the people, and the person is caused very big injury.Many dry type dust-proof blackboard erasers are arranged at present, can suck chalk powder during use, but still some chalk powder still descends slowly and lightly in air, effect is also bad, and structure is also complicated.
The utility model content
The purpose of this utility model is at existing dry type dust-proof blackboard eraser complex structure, the bad deficiency of effect, and a kind of wet type dust-proof blackboard eraser of simple in structure, good dustproof effect is provided.
The purpose of this utility model realizes by following technological means: comprise rub body and snag, snag is arranged on the one side of rub body, rub body is provided with interlayer in the one side that snag is arranged, interlayer one end links to each other with rub body, between the other end and the rub body water outlet is arranged, form water storage cavity between interlayer and the rub body, fill water-absorbing material in the water storage cavity, have water injection hole to communicate with water storage cavity on the rub body, water injection hole is sealed by the water filling port lid.
Water-absorbing material in the utility model is preferably sponge.
Compared with prior art the utlity model has following tangible advantage: in the utility model water storage cavity water-absorbing material is arranged, can store big water gaging, when erasing the board because the gravity effect and the effect that itself is squeezed, water flows out and soaks snag, effectively prevent flying upward of chalk powder, the existence of water-absorbing material can be prevented the excessive loss of sealing, in order to avoid the dustproof effect of influence.Simple in structure, the good dustproof effect of the utility model.
