Abstract

A dust removing eraser is characterized in that a cuboid-shaped box molded through plastics and provided with a strip gap, a strip edge, a dust storage bin, a dust outlet and a strong magnet is utilized as an erasing box, and a plurality of velvet strips are utilized as the erasing face. The dust removing eraser has the technical advantage that chalk dust falls into the dust storage bin and can be discharged from the dust outlet after a large amount of the chalk dust is stored. The erasing face is not stained with too much chalk dust or too much whiteboard marker blots, and is abrasion-resistant and replaceable. Other parts can be used continuously. The front face of the eraser can be adsorbed on a green board without face turning. The eraser can serve as a green board eraser and a white board eraser and is used for erasing writing on a blackboard.

Description

A kind of Dust-removing blackboard eraser

Technical field

The utility model relates to a kind of utility of the upper erasing chalk writing of teaching or white board marker writing, and the face of especially wiping can be changed, sticky ash, the green plate of positive absorption, inside can store up ash and blackboard, green plate, the general practical blackboard eraser of blank.

Background technology

The more blackboard eraser of use forms by wiping piece and wiping box on the market at present, wiping piece and be all basically felt or sponge adds flannelette and makes, the technical disadvantages of this blackboard eraser: the one, wipe face and easily adhere to very thick chalk dust, not removing chalk dust will affect the effect of wiping, removes chalk dust and bothers a little and pollute the environment.Whiteboard eraser is used wiping face of a specified duration and is adhered to the effect that very thick white board marker spot also affects wiping again, washes that these spots had not only bothered but also difficulty is washed off off.The 2nd, wipe piece and can not change, used of a specified duration fragile, thereby wipe piece, with the wiping box, become together rubbish to cause the waste of resource.The 3rd, the back side carrying magnetic of wiping box, the used time can not be adsorbed on green plate, but it is very inconvenient to pick and place blackboard eraser.The 4th, can not be general on green plate and blank, can only each with each.

Summary of the invention

In order to overcome the technical disadvantages of the above blackboard eraser, the utility model provides a kind of dust-removing blackboard eraser, it is characterized in that: form box with the cuboid of bar seam, bar rib, ash-storing bin, ash hole, strong magnet as wiping box with plastics, with several suede bands as wiping face.Its technological merit is: chalk dust is fallen in stored ash box, and chalk dust has stored many and can outwell from ash hole.The sticky not too much chalk dust of wiping face is sticky too much white board marker spot also, and wiping face is wear-resisting and can change, and other part can continue to use.Blackboard eraser is without turn-over, and front just can be adsorbed on green plate.This blackboard eraser can be worked as green blackboard eraser and be used with working as again whiteboard eraser.

In order to realize the technological merit of above-mentioned blackboard eraser, the technical scheme that the utility model adopts is: with injection machine, plastics are formed to the wiping box of a cuboid, the front of wiping box has four rule seams, positive inside that three vertical bar ribs are arranged,, a Cross slat rib, an end of wiping box has an ash hole, on ash hole, have one can be semi-open removable lid, be embedded with a strong magnet in the centre of the Cross slat rib of wiping box near the place of wiping the box front, be stained with and be with double faced adhesive tape in front and the side of wiping box

the suede band of shape.

The benefit of making wiping face of the suede band is: due to endways fine hair being arranged on the suede band, so the suede band is wear-resisting and toply can not be stained with too much chalk dust, the suede band is used old, old suede band can be thrown off and is stained with new suede band again, and other thing can continue to use.The chalk dust that suede band wiping face is wiped enters in the ash-storing bin of wiping box by four bar seams in blackboard eraser front, and ash is collected has expired the lid that can open ash hole, and ash is outwelled.Because strong magnet is the front be embedded near blackboard eraser, so blackboard eraser can be adsorbed on blackboard in front.This novel blackboard eraser can be used on the blackboard of magnetic, green plate and blank.

The beneficial effects of the utility model are: wiping face is wear-resisting can be changed and few sticky ash, wipes piece interior reservoir ash, and the green plate of positive absorption, can be general on blackboard, green plate or blank.
