We should make full use of the advantages of electric fans, use them reasonably, and make them an indispensable helper in our lives. At the same time, we should also pay attention to the limitations of electric fans and combine them with other cooling measures to cope with the hot summer.

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.
