Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to reality need, provide a kind of easy to use, structure simply, not easy dusting language teaching chalk writing erasing apparatus.
In order to realize the purpose of this utility model, the technical scheme that the utility model adopts is:
Design a kind of language teaching chalk writing erasing apparatus, comprise wiping board, correspondence is arranged at snag on wiping board; Described wiping board is made of plastics; Described snag is spliced by five rectangular-shaped hair wipers, and is also provided with baffle plate between adjacent two hair wipers; The internal end surface of described baffle plate is connected with the seamless surface of described wiping board, and the height of described baffle plate is less than the thickness at least 1.0mm of described snag; Also be provided with water holding box on the surface at the wiping board of described snag opposite face, above described water holding box, be also provided with water injection hole, and be also provided with plug in described water injection hole; Offer at least two water holes in described wiping board inside, and the diameter of described water hole is 0.5-1.0mm; Described five hair wipers are respectively the first dry hair wiper, the first wet hair wiper, the second dry hair wiper, the second wet hair wiper, the 3rd dry hair wiper from left to right; Described first wet hair wiper and the second wet hair wiper are respectively through the inner space of water hole and described water holding box.
Preferably, the height of described baffle plate is less than the thickness 2.0mm of described snag.
Preferably, the diameter of described water hole is 1.0mm.
Preferably, the length of described water holding box is less than the length of described wiping board, and the width of described water holding box is less than the width of described wiping board, and the height of described water holding box be less than the height of described wiping board.
Preferably, described water holding box is made up of flexiplast.
Preferably, described baffle plate is flexible baffle.
Preferably, described baffle plate is made up of rubber.
The beneficial effects of the utility model are:
1. the utility model is by being designed to five rectangular-shaped hair wipers by snag, the first wet hair wiper, the second wet hair wiper is combined with the water holding box of the design, makes this device not easy dusting during erasing out handwriting on blackboard, and blackboard after erasing is bright.
2. the baffle plate of the design by five hair wipers separately, can be avoided the globule to enter in mutual hair wiper, affects its result of use.
3. the diameter design of water hole is between 0.5-1.0mm by this device, too much moisture can be avoided to enter into hair wiper inside, make it enter slowly.
4. the height of baffle plate is designed to the thickness being less than snag by the design, its object is to, because its snag is flexible material, and its snag its thickness when wiping font can diminish, and therefore adopts the design can avoid causing affecting this device because height of baffle plate is too high and uses normally.
