1. Net cover
The net cover is the main part of the electric fan head. For the safety of the user, the front and rear net covers cover the fan blades, and then the front and rear net covers are fixed with a clamp ring. The function of the net cover is to prevent the human body from touching the high-speed rotating blades and causing injury accidents. Therefore, the net cover must have sufficient mechanical strength, and it is usually formed by welding with steel wires. In this way, when the fan is running, the fan blades can safely fan the air in the net cover.
2. Wind leaf
Fan blades are also called fan blades, including blades, fan blade sleeves and fan blade fixing rings. The blades are installed on the fan blade sleeves. When the blades are installed, the fan blade sleeves are fixed on the motor shaft. Tighten the hour hand. The fan blade is the main component of the electric fan to speed up the air flow, so as to achieve local cooling. Its size and shape have a great influence on the wind speed and air volume of the fan. Generally speaking, the more and larger the number of blades, the greater the air volume and the faster the wind speed, but the greater the power requirements of the motor. At present, in order to save energy and materials, most of the electric fans produced in my country use three blades. The shape of the wind leaf is mostly three-lobed.
