Description

technical field

[0001] The invention relates to a fan, in particular to an ultra-thin fan that directly forms a fan wheel by a ring plate and a plurality of bent fan blades, can reduce the overall axial thickness of the fan, is simple and reliable to assemble, and increases the starting balance and rotation stability of the fan wheel. Background technique

[0002] Conventional fans, such as the invention patent of US Patent No. 5,217,351 "Small Fan (Small Fan)", include a housing and a fan wheel. There is a base inside the casing, and a shaft tube and two coils are arranged on the base, a bearing is arranged inside the shaft tube, and the two coils are flat. The fan wheel has a rotor shell, a plurality of fan blades, a shaft and a ring magnet. The rotor shell is in the shape of an inverted bowl, and a plurality of fan blades are arranged radially at equal distances on its outer peripheral surface. One end of the shaft rod is fixed in the center of the rotor shell, and the ...
