The invention discloses a novel centrifugal fan with controllable wheels. The novel centrifugal fan comprises a blade fan (5), wherein a motor (1) is connected to the center of the blade fan (5), a housing (6) is installed on the outer side of the blade fan (5), a bracket (3) is connected to the lower surface of the housing (6), a base (2) is connected to the lower surface of the bracket (3), a dust screen (4) is installed at an air outlet, rubber wheels (7) with antiskid grains are installed on the lower surface of the base (2), a brake pad (8) is installed beside one rubber wheel (7), and silencing holes (9) are installed in the wheels (7). The novel centrifugal fan has the beneficial effects that the wheels are arranged, so that the fan is convenient to move and carry; shaking and bumping caused by pavement irregularity can be reduced by the wheels with rubber surfaces during pushing; the brake pad is arranged, so that the moving machine can stop, and the wheels can be fixed; and silencing blocks are designed, so that noise generated during movement can be reduced, and the environment is protected.
