What's even more amazing is that it has a strange shape and a streamlined and refreshing appearance.
The invention of the leafless electric fan was inspired by the hand dryer.
Because the principle of hand dryer is to force air to "brush" the water on the hand through a small mouth, the air multiplier is to let the air blow out from a cut with a width of 1.3 mm and rotate around a ring.
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.
The bladeless fan was first introduced in the UK in June 65438+1October 65438+February 2009.
On1October 26th, 2009, 165438, Hu Xiangshen, a farmer entrepreneur in Shengzhou, Zhejiang Province, applied for the invention patent of the bladeless fan.

The biggest difference of a bladeless fan is that it has no "leaves" of a traditional fan! The bladeless fan uses the technology of jet engine and automobile turbocharging to suck air through the suction hole at the bottom, and the impeller hidden inside the edge of the ring ejects the air in a circular trajectory, eventually forming an uninterrupted cold air flow.
Importantly, this air flow is more stable than the wind generated by ordinary fans.
At first, the wind "blew" out from the tiny wind slot in the middle of the ring: the huge ring supported by the bladeless fan is not a gimmick, but an important part. In its center, there is a slit 1 mm wide, from which the wind is blown out by the turbofan in the base.
