▌作品介绍：城市空气污染越来越严重，治理是个刻不容缓的问题，我设计的这个城市空气净化机，它有一对大扇叶，通过转动不仅能带动机体飞翔，还可以过滤空气中的粉尘。机体上伸缩吸收臂可以全方位的从各个角度吸收超标的空气进入机体内净化，净化完毕又从出气口排除达标的空气，周而复始，使空气达到适宜人们呼吸的标准。
此文自动翻译Introduction:Urban air pollution is becoming more and more serious, so it is an urgent problem to control it. The air purifier I designed has a pair of large blades, which can not only drive the body to fly, but also filter the dust in the air. The telescopic absorption arm on the body can absorb excessive air from all angles and enter the body for purification. After purification, the air that reaches the standard can be removed from the outlet, and the air can meet the standard of breathing for people again and again.
