Abstract

The invention provides a fan based on spherical motor drive. The fan comprises a base, wherein a spherical motor and a spherical motor driver are arranged on the base, and the spherical motor is electrically connected with the spherical motor driver; a flange boss is arranged at the shaft end of a rotor shaft of the spherical motor, a U-shaped fan support is connected to one end, far away from thespherical motor, of the flange boss, the rear end of the U-shaped fan support is fixedly connected with the flange boss, and a fan head is fixedly connected between two arms of the U-shaped fan support; and the fan head comprises a fan cover installed on the U-shaped fan support, fan blades installed in the fan cover and a driving motor, and an output shaft of the driving motor is in transmissionconnection with the fan blades. According to the fan, the spherical motor is used for replacing a part, which realizes head shaking by utilizing a mechanical structure, of a traditional fan, the fancan easily change the wind direction angle of the fan in a space semicircular surface range, the size of the fan is small, and a clamp can be replaced at the bottom, so that the fan can be applied todifferent occasions.

Description

technical field [0001] The invention relates to an electric fan, in particular to a fan driven by a spherical motor. Background technique [0002] The traditional table fan shaking head function often adopts the mechanical transmission method that the fan motor shaft is extended backward and converted into a worm gear. After the fan motor is decelerated, the rotational power of the fan motor shaft is transmitted to the lower part of the fan head through the transmission gear. The double rocker mechanism realizes the shaking of the fan. There is also a type of oscillating fan that is commonly used in multi-person apartments and is hung on the top of the ceiling. The oscillating principle of this type of fan is essentially the same as that of a desktop fan. It is also powered by a fan motor and decelerated by a deceleration device. Finally, through the relevant mechanical structural components, the function of shaking the fan's head is realized. After this kind of head shaki...
