Abstract

The utility model provides a dust-free wet erasing whiteboard eraser which has a basic structure of a water absorbing sponge body plate erasing surface arranged on an eraser support. The dust-free wet erasing whiteboard eraser is characterized in that the eraser support has a box bottom shape the inside of which is fixed with the eraser surface and is used matching with an anti-dry cover box; the reverse side of the anti-dry box cover is provided with a magnet for fixing the surface of a writing board in use. The dust-free wet rubbing whiteboard eraser can conveniently fix the eraser on the surface of the writing board, and has good sealing and anti-dry effect; the eraser box cover can be also taken as a water storing container for dipping the eraser in water and cleaning the eraser in the writing and teaching processes and guaranteeing the erasing effect of the eraser; the curve design of the eraser surface can effectively increase the contact area of the eraser with the writing board, thereby improving the erasing effect and being convenient to dip the eraser in water and cleaning the eraser; the splicing combination of the water absorbing sponge body eraser surface, the box bottom of the eraser support and the anti-dry box cover can be changed or dismantled and cleaned conveniently, the cost is low, the assembly is simple, therefore, the eraser has wide application market.

Description

A kind of dustless wet rubbing whiteboard eraser

Technical field

The utility model relates to a kind of dustless wet rubbing whiteboard eraser, belongs to the teaching aid technical field.

Background technology

For a long time, the chalk ash pollution teaching classroom, teachers and students endure the infringement of chalk dust to the fullest extent, in order to address this problem, people have developed a lot of liquid lettering pens and clipboard, and this lettering pen mostly is coloured, clipboard generally is light color as white, yellow etc., the problem of Chan Shenging is that colored ink pollutes blackboard eraser soon in actual applications, needs in time to clean, otherwise directly influences wiping effect.Someone discloses the patent application of " water spray blackboard eraser ", its main design philosophy be blackboard eraser is made box-like, splendid attire cleaning fluid or clear water in the box, the outer fixed head wiper of box, the shortcoming of this scheme is that blackboard eraser cloth and clipboard contact area are little, is difficult for changing and cleaning.

Summary of the invention

The purpose of this utility model is to provide a kind of dustless wet rubbing whiteboard eraser, and blackboard eraser is combined into the closed enclosure mode, and is air-dry and be convenient to timely cleaning in placing and using to prevent blackboard eraser, improves writing quality.

The technical solution of the utility model is achieved in that this dustless wet rubbing whiteboard eraser, its basic structure is a water-absorbing sponge body board wiper plane that is arranged in the blackboard eraser holder, and its feature comprises: the blackboard eraser holder is that the box Bottom Shape of internal fixation board wiper plane is used with anti-dried lid.

Described dustless wet rubbing whiteboard eraser, the anti-dried lid back side is provided with magnet so that in use be fixed in the clipboard surface.

Described dustless wet rubbing whiteboard eraser is provided with interface with anti-dried lid at the bottom of the described blackboard eraser holder box.

Described dustless wet rubbing whiteboard eraser, the cross sectional shape of described water-absorbing sponge body board wiper plane is plane, wave, sine curve or jaggies.

The technical solution adopted in the utility model can be fixed in blackboard eraser the clipboard surface easily, and airtight anti-dried effective, the blackboard eraser lid also can be used as tank, dips in water in order to blackboard eraser and clean in the writing and teaching process, guarantees the wiping effect of blackboard eraser; The contact-making surface of the design can effectively raising of board wiper plane curve blackboard eraser and clipboard improves wiping effect, also helps in time dipping in water and cleans; At the bottom of water-absorbing sponge body board wiper plane and the blackboard eraser holder box, the grafting combination of anti-dried lid is also conveniently replaced or pull down cleaning, with low cost, assembling simply has wide application market.
