The invention relates to the field of cooking fume exhaust and discloses a multi-claw adjustable suction-blowing range hood. The multi-claw adjustable suction-blowing range hood comprises a kitchen range, a cooking fume suction device I, a blowing device II and a control panel. The cooking fume suction device I and the blowing device II are mounted on the kitchen range, and the control panel is arranged on the cooking fume suction device I, the blowing device II or the kitchen range. The multi-claw adjustable suction-blowing range hood has advantages that current situations of central arrangement and static state of a cooking fume suction port of an existing range hood are changed thoroughly, and compared with a single-fan range hood, the suction-blowing range hood has advantages of noise reduction and absorption efficiency improvement; two mounting modes are designed to meet various demands of users; by adoption of a rotary valve structure, an inner cavity port of a pipeline can be adjusted arbitrarily in position to aim at cooking fume; a pipeline II can be bent arbitrarily to make the device closer to a cooking fume generation position, and accordingly absorption efficiency is improved.
