Abstract: A fan assembly including a base arranged to support the fan assembly on a surface, an air flow generator that is arranged to generate an air flow, and an air outlet that is arranged to emit at least a portion of the air flow from the fan assembly is provided. The air outlet is arranged to be oscillated relative to the base. The fan assembly further includes a controller that is arranged to control the oscillation of the air outlet relative to the base. The controller is arranged to vary an oscillation speed of the air outlet for each oscillation.

Abstract: An air circulator includes a blower unit that is provided with an airflow opening on a front side of the blower unit. A grill is provided in the airflow opening, and is provided with airflow guide blades in a spiral manner Each of the airflow guide blades is convex toward an airflow direction between its inner end portion and its outer end portion to form the grill three-dimensionally. The grill further includes a circular ring that intersects with the airflow guide blades.

Abstract: The present disclosure relates to a fan and a method and device for controlling the fan. The method includes controlling, via a support rod control device, a swinging motion of the swingable support rod, wherein the support rod control device is provided between the swingable support rod and the fan base; determining, when the swingable support rod is swinging, a current swing angle of the swingable support rod; determining a current distance between the fan and a user; determining, based on the current distance and the current swing angle, an axial rotation angle of the fan head; and rotating the fan head based on the axial rotation angle to direct air at the user.
