队员们,想想看,我们生活中有什么物品和工具的工作原理和这个神奇的“吸力”机非常相似呢?对了,第一个就是吸尘器,它也有个“吸”字。吸尘器内部有一个抽风机和风叶轮,它会产生很快的转速,同时产生“吸力”把垃圾和灰尘吸入。第二个也是我们家庭厨房中常用的脱排油烟机。同样,它的内部也有一个电动机和风轮,在高速旋转的时候产生气压差,形成“吸力”把油烟吸入内部处理。 Team members, think about it, what are the objects and tools in our life that work in very much the same way as this magical “suction” machine? Right, the first one is the vacuum cleaner, which also has a “suction” . The vacuum cleaner has an extractor and impeller inside, it will produce a very fast speed, at the same time produce “suction” to the garbage and dust inhalation. The second is also commonly used hoods in our home kitchens. Similarly, it also has a motor and rotor in the interior, producing a pressure differential at high speeds of rotation, creating a “suction” that sucks the fumes into the interior.
