I want to be an inventor, I want to invent a kind of chalk dust absorber, which is composed of a filter and cleaning paper and artificial speech system composition, the teacher put it in the hands of the chalk dust fall, when writing it automatically absorbed into the machine, then through the filter and purification paper, again by artificial speech system put them back made of chalk, which is not only a waste recycling effect, but also can prevent the chalk dust brings bad effect
我想当发明家,我想发明一种粉笔灰吸收器,它是由过滤器和净化纸还有人工语音系统组成的,老师把它戴在手上,写字时掉落的粉笔灰它会自动吸收进机器,然后通过过滤器和净化纸,再由人工语音系统把它们再制造成粉笔,这样不仅有了废物回收利用的效果,还能预防粉笔灰给人带来的不好效果
网友们觉得我的想法咋么样,我正在做这种机器哦
