Referring to fig. 9 and 10, under the condition that the cooking utensils right side of two kitchen ranges were cooked, keep off the cigarette board 6 and open, the oil smoke volume is great on the right side this moment, then actuating mechanism 51 starts, make pendulum rod 523 rotate to the left side, the lower extreme of drive connecting rod 533 upwards rotates left, slider 539 upwards promotes, because unilateral atress, the left end of connecting rod 542 upwards rotates, make first baffle 41 rebound, until sheltering from corresponding first air inlet region 211, thereby close first air inlet region 211, make left flow reduce, make range hood be in the state of opening to the right, thereby increase the air inlet speed of right side culinary art side oil smoke. Thereafter, if the initial state needs to be restored, the motor 511 is simply rotated reversely to return the swing lever 523 to the initial state (with the end connected to the output shaft 512 up).

Referring to fig. 11 and 12, under the condition that the cooking utensils left side of two kitchen ranges were cooked, smoke baffle 6 is opened, the oil smoke volume is great on the right side this moment, then actuating mechanism 51 starts, make pendulum rod 523 rotate to the right side, the lower extreme that drives connecting rod 533 upwards rotates right, slider 539 upwards promotes this moment, because unilateral atress, the right-hand member of connecting rod 542 upwards rotates, make second baffle 42 rebound, until sheltering from corresponding second air inlet region 212, thereby close second air inlet region 212, make the flow on right side reduce, make range hood be in the state of opening left, thereby increase the air inlet speed of left side culinary art side oil smoke. Thereafter, if the initial state needs to be restored, the motor 511 is simply rotated reversely to return the swing lever 523 to the initial state (with the end connected to the output shaft 512 up).
