Principle: In fact, the air is not compressed. The principle is similar to that of an airplane wing. The wall thickness of the ring above is not uniform. That is to say, the diameter of one side of the ring is relatively large, and the other side is relatively small, so that it blows out from the bottom. After the air passes through the ring, it will weaken the surrounding air pressure, thereby driving the surrounding air and enhancing the air flow. This is a design that is not only beautiful, but also extremely practical. Because the driving air below does not require too much flow, the noise is very low. Because the driving air drives the surrounding air, the air volume is higher than that of ordinary electric fans. In addition, ordinary fans use blades to cut air to drive airflow, which is unpleasant. And this fan is a continuous flow of air, so it is more comfortable. Also, this fan is not as top-heavy as normal fans, so it is more stable.
It is best to keep the fan at a distance of more than 2 meters. If the space in the home is not large, you can choose to blow the fan against the wall and let the wind reflect.
