Although handheld fans are compact, their internal structure is not simple, mainly composed of the following parts:
1. Motor: The core component of a handheld fan, responsible for converting electrical energy into mechanical energy and driving the fan blades to rotate. Generally, micro DC motors are used, which have small size, low noise, and high efficiency.
2. Fan blades: responsible for generating airflow, usually composed of 3-5 plastic or metal blades. The shape and angle of the blades have been carefully designed to optimize airflow and reduce noise.
3. Battery: Provides power for the motor, usually using rechargeable lithium batteries, whose capacity determines the fan's battery life.
4. Circuit board: It controls the functions of switching, speed regulation, charging, etc. of the fan, and is the "brain" of the handheld fan.
5. Shell: protects internal components and serves an aesthetic purpose. Generally made of ABS plastic material, lightweight and durable.
In addition to the main components mentioned above, some high-end handheld fans may also include the following functional modules:
LED lights: provide lighting function, convenient for night use.
Aromatherapy box: can add aromatherapy essential oils to blow out a cool breeze with fragrance.
Humidifier: It can spray water mist, increase air humidity, and bring a cooler experience.
The internal structure design of the handheld fan is exquisite, and all components work together to bring us a cool and comfortable experience.
It should be noted that the internal structure of handheld fans of different brands and models may vary, but the basic principle is the same.
