Description
Technical field
The utility model relates to instructional technology fields；More particularly to a kind of device for blackboard eraser.
Background technique
With the development of science and technology, many schools have begun using Concerning Multimedia-related Teaching Methodologies, pass through multimedia on classroom
Teaching notes, experimentation etc. are shown, however traditional blackboard does not step down from the stage of history, instead since it easily writes, easy-to-use, Yi Xiu
Change, is cheap and still occupy consequence in teaching.Currently, blackboard used in school, China is still black with tradition
Based on plate, the wiping method of this blackboard is hand-held blackboard eraser, is wiped repeatedly on blackboard, and blackboard eraser overall volume is small, not side
Just force is held, and the area that blackboard eraser wipes every time is small, wipes blackboard with traditional blackboard eraser, it is cumbersome and time consuming.
Especially education of middle and primary schools, using blackboard carry out writing on the blackboard, writing on the blackboard amount is very big in teaching process, to writing on the blackboard into
Row erase process is time-consuming longer, wastes instructional blocks of time, and the continuity of teaching is affected, and will affect quality of instruction.Furthermore black
In the use process of blackboard eraser, the corner of the wiping surface on blackboard eraser is easy to appear the case where collapsing, and leads to the wiping of blackboard eraser
Wiping ability is lost in the corner in face, and wiping repeatedly is needed during to blackboard-cleaning, and efficiency of erasing reduces several times.And
And it is carried out in erase process to writing on the blackboard, while the chalk dust that can be generated also influences the health of Faculty and Students.
Therefore, it is convenient, laborsaving when a kind of use how can just to provide, and efficiency of erasing is high, more healthy blackboard eraser dress
It sets, becoming those skilled in the art has technical problem to be solved.
Utility model content
In view of the above shortcomings of the prior art, the technical problem to be solved by the utility model is to how to provide one kind makes
Used time is convenient, laborsaving, and efficiency of erasing is high, more healthy device for blackboard eraser.
