When did the electric fan start to appear?
In 1883, the factory began mass production of this type of desktop fan.
Where does the fan drip the oil?

How long can the electric fan be timed?

Why does the electric fan always rotate clockwise?
The fan blade of a conventional fan has a tilt angle (the steering is designed from the angle of the tilt angle). The motor causes the fan to rotate and the space-time is compressed, causing air flow (resulting in wind). The direction of flow is related to the direction of the fan's rotation and the inclination of the fan blade.
Why can an electric fan choose only 123 winds, and this discrete value instead of zero to three continuous type?
Because, for example, Class 1.5, the volume of air can be settled by the distance between the fan and the person.
