铁扇子，也称为电扇，是一种使用电力驱动的扇子，用于制造风流以达到降温或通风的目的。在英文中，电扇通常被称为 "electric fan"。

When it comes to fans, there are different types of fans that serve different purposes. For example, there are hand fans, folding fans, and electric fans. Among these, electric fans are becoming increasingly popular due to their convenience and efficiency. They are especially useful in hot weather when manual fans may not be sufficient to cool the air.

Electric fans are designed to be used in various settings, from homes to offices and even in outdoor events. They come in different sizes and designs, with some featuring adjustable blades and speeds to achieve the desired airflow. Some electric fans also have additional features like thermostats to automatically adjust the fan speed based on the room temperature.

The use of electric fans not only provides a comfortable environment but also helps in reducing energy consumption by reducing the need for continuous manual扇动（扇子摆动）. This makes them an environmentally friendly option as well.

In conclusion, electric fans are a practical and efficient solution for cooling and ventilation. They are a must-have item in any household or office, especially during hot summer months.
