Description

Automatic dust-absorbing blackboard eraser

Technical Field

The utility model relates to a teaching aid field, concretely relates to automatic dust absorption blackboard eraser.

Background

The teaching is the basis for centuries. Education is the mark of standing foundation and flourishing nationality. The importance of education is also deeply known in the 21 st century, and the education is known to have the status of forensics, foundation and global in the development of economic society and ethnic joy. Science and education are the foundation of science and technology, which is the first productivity, and thus the importance of education can be seen. In education, teachers and classrooms are indispensable components, and the blackboard eraser in teaching articles also belongs to an important auxiliary component.

The existing blackboard eraser has the defect that if a person with a high height writes on the blackboard, the person with the low height needs to erase the blackboard by means of external force or foreign objects. The blackboard eraser is inconvenient to use, when a student wrongly writes characters, the characters cannot be erased in time, the blackboard eraser needs to be found and then erased, when the blackboard is large, all chalk marks can be erased only by moving for many times, and when the height of the blackboard is not enough to erase, a stool needs to be carried for many times, so that time and labor are wasted. Meanwhile, the existing blackboard eraser can only erase writing left on the blackboard by chalk, and dust floating in the air in the erasing process cannot be effectively absorbed. When the hand cleaner is used for a long time, other skin problems such as dryness and the like of the skin of the hand can occur, when students or teachers erase the hand cleaner, dust is likely to enter the oral cavity and eyes, and great harm can be caused to the body in the past.
