This product is inspired by the fan blade hand dryer.
The principle of hand dryer is to force air to pass through the water on a small mouth brush, and the air multiplier is to let air blow out from a cut with a width of 1.3mm and rotate around a circle.
Because the air is forced to blow out of this circle, the amount of air passing through can be increased to 15 times, and the speed can be increased to 35 km/h.
