Description

Dust-absorbing blackboard eraser

Technical Field

The utility model relates to a blackboard eraser technical field, more specifically say a dust absorption blackboard eraser with dust absorption function.

Background

At present, teachers can repeatedly write some knowledge points on a blackboard by using chalk in teaching work so as to facilitate students to learn and understand. However, when the blackboard eraser is used for erasing chalk marks, some chalk dust is generated, so that the ground is polluted, and the chalk dust falls on clothes and skin of a human body, which brings inconvenience. Even the medicine can be inhaled into human body, which directly affects the health of teachers and students. Some current dust-absorbing blackboard erasers can absorb chalk dust into the blackboard erasers, but the chalk dust leaks out of the suction holes during shaking, so that secondary pollution is caused, and cleaning difficulty is increased.
