Abstract: A shining fan structure for displaying images of patterns or characters by reflection mainly includes a fan. A plurality of blades of the fan are provided with reflective patterns or characters. Light-emitting elements are provided on the periphery of the fan base. Each light-emitting element is angled to directly irradiate the front of the blade. When the fan rotates, the light-emitting elements provided on the periphery of the base irradiate the patterns or characters provided on the blades with the lightening frequency being synchronous with or different from the rotation speed of the fan, a shining effect can be seen from the front or side of the fan by reflection or transmission.

Abstract: A heat-dissipating fan of the invention has an axle, a bearing, a rotor and a stator. The axle and the bearing are made of a ceramic material, and are located at a central location of the rotor and the stator. The bearing is a hollow cylinder integrally formed into a single body, and has a central hole and a recess at its bottom. The axle penetrates through the central hole of the bearing to contact the recess. A magnetic force center of the silicon steel sheet is at a level lower than that of the magnetic bar to generate radial and axial force components, allowing stable rotation of the rotor. The heat-dissipating fan of the invention provides advantages such as low friction, lower noise, low energy consumption, high performance and high stability.

Abstract: A ceramic bearing structure is constructed to include an axle bush having an axially extended axle hole, and an axle pivoted to the axle hole of the axle bush, the axle bush having a radial open chamber extended across the axle hole. The radial open chamber diminishes the material of the axle bush, reduces the contact area between the axle and the axle bush, and provides a spacious lubrication grease accumulation chamber.

Abstract: A cooling fan having flashing light effect, having a fan base, a set of blades and a plurality of light emitting diodes. The fan base further comprises a plurality of supporting levers connected to a common base. Circular axial perforation is formed in the common base, and a plurality of slots and light guides are installed near a periphery of the common base. Each light emitting diode is embedded in the corresponding slot and electrically connected to the circuit board of the set of blades.
