The structure of Hongyun fan is similar to that of desktop electric fan, the main difference is the design of fan mesh cover. Lucky fan is called rotary fan, which is to design its front mesh cover into a rotatable grille. It is precisely because of the rotation of the grille that the wind it blows out changes within a certain range, making people feel soft and comfortable.

There are usually two ways to drive the grid of Hongyun fan to rotate: one is to use synchronous motor, that is, add a emblem synchronous motor to the rotating fan and drive the grid to rotate after passing through the reduction gear; The other is to use the motor of the rotating fan to drive the fan blades to rotate through the deceleration mechanism, which is similar to the swinging device of the desk fan, and the rotation speed of the grille varies with the speed of the fan blades.
