The casing 10 has a separation mechanism capable of separating the gas moving in the circumferential direction of the casing 10 into the first gas and the second gas.
In some embodiments, the housing 10 is a volute having a volute cavity therein, the volute cavity includes a placing cavity and an air outlet channel, and the impeller 11 is disposed in the placing cavity and is rotatably connected to a sidewall of the placing cavity.
