Description

technical field

[0001] The invention relates to a fan, in particular to a fan wheel directly composed of a ring plate and a plurality of bent fan blades, which can omit the existing rotor shell, further reduce the overall axial thickness, make the assembly simple and reliable, and increase the starting balance of the fan wheel and a thin fan with stable rotation. Background technique

[0002] Conventional fans, such as the invention patent of US Pat. No. 5,2 17,351 "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 the 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, an...
