新型除尘黑板擦的研究与改进

粉笔作为教学必备的工具,在给我们带来便捷的同时也带来了很多隐性的伤害。随着科技的发展,很多人开始着手研究如何避免粉笔灰的二次伤害,并开始对黑板、粉笔、黑板擦等进行研究和改进。论文是基于吸尘器原理对黑板擦的除尘问题进行研究和探索,在现有的几种黑板擦的基础上,通过大量的实验,不断地尝试,最终确定出一种采用电力驱动并能实现自动擦拭的新型黑板擦。

A New Research and Improvement of the Dust Removal Blackboard Eraser

As an essential tool of teaching,chalk brings convenience as well as recessive damage at the same time.With the development of science and technology,many people begin to settle on a question about how to avoid secondary damage of chalk dust,and to study and improve the blackboard,chalk board,etc.The thesis is based on the principle of vacuum cleaner to do a research of the cleaning of the blackboard eraser.On the basis of a several existing blackboard eraser,through a lot of experiments,trial and error,we finally developed a new blackboard eraser,which is power-driven and automatic-wiping.
