"tower fan"的定义和意义

What is a "tower fan"?

A tower fan is a type of fan that has a tall, narrow design, making it ideal for saving space while providing airflow in a room. It works by drawing in air through vents at the bottom and pushing it out through the top to circulate cool air. Tower fans are often quieter than other types of fans and can offer different speed settings, the ability to move from side to side, and sometimes even air purification features. They are commonly used in homes and offices to cool small to medium-sized areas and are easy to move around due to their lightweight design.
