Further, when the driving end of the driving member 41 is retracted, one end of the first connecting rod 431 first rotates around the pin 433, and then moves linearly; in this way, the driving mechanism 4 is first driven to start to recover and flip, and then drives the driving mechanism 4 to the starting position of the linear moving position. In this way, through the cooperation between the driving member 41, the first connecting rod 431 and the pin 433, when the air suction port 112 needs to work, the air suction port 112 can be opened to suck away the smoke, thereby ensuring the freshness of the air in the kitchen; when the air suction port 112 is not working, the air suction port 112 can be blocked to reduce the backflow of smoke and improve the aesthetics of the range hood.
