when the right side furnace end below the range hood is used, the second sensor assembly (6) detects a signal with high oil smoke concentration, the first sensor assembly (5) detects a signal with low oil smoke concentration and transmits the signal to the control system, the adjusting structure (4) acts to inflate the first air cavity (3a), and the width of the first air inlet channel (11a) is reduced by expanding the first air inlet channel (11a) towards the right side of the first air cavity (3a), so that the suction and discharge capacity of the second air inlet channel (11b) is increased, and the suction and discharge capacity of the first air inlet channel (11a) is reduced.
