Abstract: An impeller is provided, including a metal housing, a shaft, and a plastic member. The metal housing has a shaft mounting hole. The inner surface of the shaft mounting hole includes three or more contact points, and the contact points are closer to the shaft than other portions of the inner surface of the shaft mounting hole. The shaft passes through the shaft mounting hole and is affixed by the contact points. The metal housing divides the shaft into an upper section, a middle section, and a lower section. The plastic member passes through the shaft mounting hole and is in contact with the middle section.

Abstract: The disclosure relates to an asymmetrical double-outlet blower, including an upper case, a lower case and an impeller. The upper case includes an inlet. The lower case and the upper case are assembled to form a housing having an accommodation space, and form a first outlet and a second outlet. The accommodation space is in fluid communication with the first outlet, the second outlet and the inlet. The first outlet and the second outlet are disposed on a lateral periphery of the housing and face two opposite directions, respectively. An opening cross-sectional area of the first outlet is less than an opening cross-sectional area of the second outlet. The impeller is accommodated within the accommodation space of the housing, spatially corresponding to the inlet, and rotated around a rotation axis. An airflow is inhaled through the inlet and transported to the first outlet and the second outlet, respectively.

Abstract: A fan includes a base, a motor and an impeller, and the motor includes a sleeve, a rotor, a position limiting element and a composite elastic element. The sleeve is disposed on the base, and the sleeve has a bottom portion and a side wall, which constitute an accommodation space. The rotor has a rotating shaft disposed within the accommodation space, and the rotating shaft has an outer wall. An annular groove is formed on the outer wall and has a surface. The position limiting element is disposed on the sleeve and extended from the side wall toward the rotating shaft, and the position limiting element has a bottom surface. The bottom surface faces toward the bottom portion, and the bottom surface is interfered with the surface, thereby eliminating the gap between the bottom surface and the surface. Therefore, noise of the up and down vibration is avoided from generating.

Abstract: A centrifugal fan includes a frame and an impeller. The impeller is disposed within the frame. The impeller includes a hub, a first blade group and a second blade group. The hub includes a center part, an inclined part and a connection part. The first blade group is connected with the connection part of the hub. The second blade group is disposed on the inclined part of the hub. There is a first distance between the second blade group and the first blade group. There is a second distance between the second blade group and the center part of the hub.
