[0002] A fan is an electrical device that uses an electric motor to rotate blades, accelerating air circulation. They are primarily used for cooling and circulating air, and are widely used in various locations. Portable fans are small, lightweight, and easy to carry. They operate similarly to regular fans, using a motor to rotate the blades to generate airflow. Portable fans are compact and lightweight, making them easy to carry and store, often handheld. Their compact size and light weight make them convenient for both indoor and outdoor use.

[0003] A handheld fan usually includes a fan body, a fan bracket and a connecting base. The connecting base is used to combine and connect the fan body and the fan bracket.
