The components of a fan mainly involve its physical structure and materials.
1. Mechanical structural components
Fan blades:
Material: Usually made of plastic (such as polypropylene, nylon, etc.) or metal (such as aluminum, steel, etc.).
Function: The fan blade is a key component of the fan and is responsible for driving the air flow. Its shape, number and angle will affect the fan's performance such as air volume, wind speed and noise.
Motor:
Material: The motor contains electromagnets, coils, bearings and other components, which are usually made of materials such as iron, copper, aluminum, plastic and lubricants.
Function: The motor is the power source of the fan and is responsible for driving the fan blades to rotate. The type of motor (such as DC motor, AC motor) and performance will affect the fan's power consumption, speed and noise.
Bearing:
Material: Bearings are usually made of metal (such as steel, copper) or plastic and are coated with lubricants to reduce friction.
Function: Bearings are used to support and reduce friction between the motor shaft and the fan blades to ensure that the fan can run smoothly and efficiently.
Bracket and frame:
Material: Usually made of metal (such as iron, aluminum) or plastic.
Function: Bracket and frame are used to support and fix fan blades, motors and other components to ensure the stability of the overall structure of the fan.
Casing:
Material: Usually made of plastic or metal.
Function: The casing is used to protect the internal components of the fan from damage and play a role in beauty and dust prevention.
2. Electronic control components (for fans with electronic control functions)
Circuit board:
Material: The circuit board is usually made of fiberglass, copper and other electronic components.
Function: The circuit board is the electronic control center of the fan, responsible for receiving and processing signals from input devices such as switches and remote controls, and controlling the operation of the motor.
Switch and remote control:
Material: Switches are usually made of plastic and metal, and remote controls contain plastic casings, electronic components and batteries.
Function: Switches and remote controls are used to control the switch, speed, shaking head and other functions of the fan.
Sensor (for smart fans):
Material: Sensors are usually made of semiconductor materials and other electronic components.
Function: The sensor is used to detect environmental parameters (such as temperature, humidity, etc.) and automatically adjust the operating status of the fan according to the preset conditions.
3. Other auxiliary components
Screws and fasteners:
Material: Usually made of metal (such as iron, stainless steel).
Function: Screws and fasteners are used to fix the various parts of the fan together to ensure the stability of the overall structure.
Power cord:
Material: Usually composed of a plastic insulation layer and an internal copper conductor.
Function: The power cord is used to connect the power supply to the fan's motor to provide power to the fan.
The components of the fan include mechanical structural components (such as fan blades, motors, bearings, brackets and frames, housings), electronic control components (such as circuit boards, switches and remote controls, sensors), and other auxiliary components (such as screws and fasteners, power cords).
