Abstract: An air blower includes an impeller, a motor and a blower housing. The blower housing includes a first housing member for receiving the motor and a second housing member for receiving the impeller. The first and second housing members are mounted to each other. Two opposed air outlets are formed at an end of the first housing member remote from the second housing member. Each air outlet is formed by an outwardly inclined cutout. The cutout is bounded by two inclined sides. An angle A formed by each inclined side and an axial direction of the blower is in the range from 0 to 45 degrees. Radial lines extending from one inclined side of one air outlet and the adjacent inclined side of the other air outlet form an angle B in the range from 15 to 45 degrees.

Abstract: An air flow regulating device includes a housing, an air supply unit and a circuit board which are arranged inside the housing. The air supply unit includes an impeller and a single-phase permanent magnet brushless motor configured to drive the impeller. The single-phase permanent magnet brushless motor includes a stator and a rotor which can rotate relative to the stator. The stator includes a stator core and a single-phase winding wound around the stator core. The rotor includes a shaft and a permanent magnet fixed to the shaft. Numbers of magnetic poles of the stator and the rotor are the same and not greater than six. An outer diameter of the stator core is less than 35 mm and/or an axial thickness of the stator core is between 10 mm and 20 mm.
