In summer, the fan is an indispensable standing. A fan refers to a device that relies on the wind to cool the wind. The electric fan is a device that generates airflow by electric driving, and the fan is configured to rotate after being energized, and the natural wind is cooled to achieve the effect of cooling. The rotation of the three blades brings a cool wind, and the wind speeds of different gears are different. The wind speed is higher and the wind is cooler. You can make an adjustable fan and do it yourself.
