Description
Technical field
The present invention relates to realia field more particularly to a kind of dustproof blackboard and its application methods.
Background technique
Multimedia assisted instruction tool application is more and more extensive at present, but traditional teaching method using chalk writing
Still it can not be fully substituted.In the teaching using chalk writing, the generation of dust will lead to, chalkboard eraser erases the board,
It will lead to dust to disperse everywhere, not only influence the health of clergy, but also can bring to the health of student and growth huge
It influences.Usual situation achieved the purpose that using dustproof blackboard sassafras it is dust-proof, in Chinese Publication No. CN201544663U, publication date
It is on August 11st, 2010, invention and created name is the blackboard eraser of anti-dust, discloses a kind of blackboard of anti-dust in this application
It wipes comprising blackboard eraser body, the bristle heteropleural surface middle part of blackboard eraser body are equipped with one handle, and the top of blackboard eraser is equipped with saturating
Bright dust cover, handle is in dust cover.Compared with prior art, which can effectively prevent dust to pollute hand, be suitable for common
The blackboard of chalk writing uses.But it is easy to lose in the process blackboard eraser used.And fixed blackboard can be brought not in teaching
Convenient, the writing on the blackboard of fixed blackboard is a challenge for short a clergy.Although the relatively fixed formula of orbit movable blackboard
Blackboard has progress, but still cannot overcome influence of the dust to clergy and student health.It would therefore be highly desirable to be designed as teaching job
Personnel design a kind of blackboard easy-to-use, energy is dust-proof.
Summary of the invention
