The rotating function of the bladeless fan is mainly realized by the rotating motor installed at the lower part of the fan driving the crankshaft connected at the bottom. How is it achieved?

Vaneless fans, also known as air multipliers, can produce natural and continuous cold air. Because it doesn't have a blade, it won't cover the dust and won't hurt the fingers of curious children. What's even more amazing is that it has a strange shape and a streamlined and refreshing appearance. 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. 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. 20 1 1 The second generation was listed in Hong Kong in February. ? The working principle of the bladeless fan is as follows: the 40W motor in the base sucks 33L air into the fan base every second, and after being accelerated by the cyclone accelerator, the air circulation speed is increased by about 16 times, and it is surrounded by the annular inner lip of the bladeless fan head, and its surrounding force drives the air near the fan head to enter the fan head and blow out at high speed. ? 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. The air volume it produces is equivalent to the best fan on the market at present. This bladeless fan also has a variable frequency wind speed adjustment device, which is convenient for users to adjust the wind speed according to the actual situation. The air volume increases evenly, does not impact the voltage, and has low energy consumption, which is half of that of ordinary fans. At the same time, the air flow will drive the air in the ring to move forward through the viscous force. The superposition of the two effects can theoretically make the actual amount of air blown out 15 times that of the air flowing through the base! ?
