When using a household electric fan, there are also some things to pay attention to. Firstly, it is necessary to ensure the safety of the power cord and avoid safety hazards caused by wire damage or aging; Secondly, it is necessary to regularly clean the fan blades and casing to maintain the cleanliness and hygiene of the fan; Finally, it is important to avoid prolonged continuous use of fans to avoid adverse effects on the body.

The working principle of an electric fan is relatively simple. When the motor starts, it drives the fan blades to rotate, causing air to flow under the push of the fan blades. This flowing air can take away the heat from the surface of the human body, making us feel cool. At the same time, the wind speed of the electric fan can be adjusted by adjusting the motor speed, allowing us to adjust the wind speed according to personal needs.
