Abstract

The utility model discloses a dust collecting blackboard eraser, which is characterized in that a minitype dust collector and a dust storage box and a power supply are arranged in a grab handle of the blackboard eraser; the minitype dust collector positions between the grab handle and a brush hair arranging layer, connects with the dust storage box and the power supply, and absorbs the external dust through the air holes on the brush hair arranging layer. The dust collecting blackboard eraser makes corresponding improvements on the basis of the existing blackboard eraser, to make the blackboard eraser have the dust collecting function when being used after the minitype dust collector is arranged in the grab handle. Not only the improvements reasonably use the internal space of the grab handle of the former blackboard eraser, but also the difficulty of the improvements is relatively low. In addition, the dust collecting blackboard eraser is very suitable for popularization, with good market prospect.

Description

A kind of dust absorption blackboard eraser

Technical field:

The utility model relates to a kind of teaching aid, particularly a kind of dust absorption blackboard eraser.

Background technology:

The blackboard eraser that existing quilt generally adopts, there are some shortcomings in actual applications, whenever classmates are sitting in the classroom in the class, be a teacher and pick up blackboard eraser, when wiping the letter written with chalk on the blackboard, chalk dust will fly upward in the classroom everywhere, and the teacher who also does is all over the body sometimes, so we want to make a kind of new blackboard eraser in conjunction with existing dust catcher.
