    摘要： An oil return structure for fan includes a base, a bearing, a retaining ring and a rotor. The base has a bearing cup internally defining a receiving space for receiving the bearing therein. The bearing has a centered and axially extended shaft hole. The retaining ring is located at a front end of the bearing and has a central hole. The rotor includes a hub and a shaft. The shaft is extended through the central hole of the retaining ring into the shaft hole of the bearing, and is provided with an annular groove corresponding to the retaining ring. Oil in the bearing flowing to the annular groove during fan operation is centrifugally pulled out of the shaft and then caught by the retaining ring, from where the oil returns to the bearing. Therefore, loss of oil from the bearing is largely reduced to ensure extended fan service life.

    摘要： Provided is a BLDC motor for a hair dryer, which includes high strength plastic parts integrated through injection molding. Thus, the number of parts is decreased to thereby decrease manufacturing costs and the weight of the BLDC motor. Furthermore, a sirocco fan installed in the BLDC motor is directly coupled to an outer circumferential surface of a rotor housing so as to optimize an assembling structure of the sirocco fan, thereby stabilizing the rotation thereof. Accordingly, vibration and noise due to rotation can be reduced, and an amount of introduced air can be maximized. To this end, the BLDC motor includes a rotor housing including permanent magnets on an inner surface thereof, and a shaft hole in a central portion thereof to receive a shaft, wherein a sirocco fan for blowing air is coupled to an outer portion of the rotor housing, a rotor frame coupling the shaft to the rotor housing to integrally rotate them, a stator core around which a coil is wound to interact with a magnetic field formed on the permanent magnets, thereby generating torque, a PCB coupled to a lower portion of the stator core by a screw, a base bracket including a support protrusion on an upper outer portion thereof to support the stator core, and a bearing housing coupled to an upper portion of the base bracket to support a ball bearing, and including a removal prevention protrusion in a lower outer portion thereof to prevent removal of the stator core.

    摘要： A heat-dissipation fan comprises a hollow cylinder body, a fixing pillar, a stator, a fan wheel, a bearing and bearing plate. The fixing pillar comprises a free end and a fixing end fixed at the hollow cylinder body. The stator is installed at the hollow cylinder body being installed at the bearing plate. The fan wheel comprises a top plate, an outer ring wall, an inner ring wall and a penetration hole formed at the top plate. The inner ring wall surrounds the penetration hole, the hollow cylinder body and the stator are located between the outer ring wall and the inner ring wall, and the bearing is coupled to the inner ring wall. The free end of the fixing pillar is protruded to a top surface of the top plate, which results a supporting surface and the top surface being spaced apart by a first spacing.
