Description

Technical Field

[0001] The invention belongs to the technical field of intelligent fans, and in particular relates to an intelligent fan with a folding function. Background Art

[0002] A fan is a household appliance that uses an electric motor to drive the blades to rotate to accelerate the circulation of air. It is mainly used for cooling and circulating air, and is widely used in homes, classrooms, offices, shops, hospitals, hotels and other places. Traditional fans are mainly composed of parts such as heads, blades, mesh covers and control devices. The heads of traditional fans include motors, front and rear mesh covers and shaking air supply mechanisms.
