technical field

The invention relates to the technical field of fans.

Background technique

An electric fan is referred to as an electric fan, also known as a fan or a fan. It is a household appliance that uses a motor to drive the fan blades to rotate to accelerate the circulation of air. It is mainly used for cooling, relieving heat and circulating air. Widely used in homes, offices, shops, hospitals and hotels and other places. The floor fan is mainly composed of fan head, fan blade, net cover, pole, base and control device and other components. The pole is fixed on the base, the fan blades are installed on the fan head, and the net cover is set outside the fan blades; the fan head generally includes a motor, a motor cover, fan blades, a wind net and an oscillating air supply mechanism, and the motor drives the fan blades to run . Traditional electric fans are generally divided into several wind speed adjustments instead of stepless speed regulation. This is because when the stepless speed regulation device is adjusted to a certain frequency, the fan will be damaged by components such as the motor and the casing. Resonance causes buzzing sound, so the gears of several speed adjustments avoid the resonance frequency. However, fans that cannot fully realize stepless speed regulation have been gradually difficult to meet the needs of existing markets and users. Therefore, it is necessary to provide a new fan structure that can realize stepless speed regulation.
