The inspiration of the fan blade is the air blade dry hand device. The principle of the air vane dryer is to force the air through a small opening to "blow" dry hands on the water, the air multiplier is to let the air from a 1 mm wide, around the ring amplifier turn Blow out the moving cut. As the air is forced out of this circle, the air volume can be increased by 15 times the original, it can reach 35 kilometers per hour. Air flow is more stable than the wind generated by ordinary fans. It produces the amount of air equivalent to the current market performance of the best fans. Because there is no fan blade to 'cut' the air, the user will not feel the stage of shock and wave shaped stimulation. It makes you feel more natural cool by continuous air flow.

Note that this is the British wind fan James Dyson (James Dyson) of the invention, it is called "air increases times machine" (English: Air Multiplier), the new method reduces the power consumption by 1/3 than the general electric fan, but also because it has abandoned the traditional electric fan blade parts, innovation the leather type fan, the fan is safer, more energy-saving, more environmental protection, therefore, no fan of American science and technology magazine to be one of the world's ten great inventions of 2009. But the first generation of fans in the energy saving under the premise of leading to smaller wind, and thus its listing and sales of products in order to increase wind power and had to increase the power consumption.

To make the air pass through an energy efficient brushless engine base and to increase the flow of air. Strong 15 times, and then 118 gallons per second to make the air discharged from the propeller shaped.

Dyson said hydrodynamic engineers they spent 4 years to simulate hundreds of times, was able to accurately measure the engine base diameter and propeller like machines needed, and to be optimal, and the fluctuation of the air is known as a Laser Doppler device by mapping out of the Annometry. [2]

The working principle is: no leaf fan base with 40 watts per second electric motor to 33 liters of air suction fan base, by cyclone accelerator after air circulation, the maximum speed increased by about 16 times, with no leaf fan fan head ring around the lips, around force drives the fan head near the air entered the fan head, and blown out at high speed.

The use of jet engines and motor vehicles Technology, through the bottom of the suction hole suction air, the inner edge of the ring edge of an impeller to the circular trajectory of the air out, and ultimately the formation of a continuous flow of cold air. It is important that the air flow is more stable than the wind generated by the ordinary fan. It produces the amount of air equivalent to the current market performance of the best fans. The bladeless fan with frequency conversion speed regulating device size, convenient user adjustable speed according to the actual situation of the size, volume increase evenly not impulse voltage, low energy consumption, energy consumption is half of the ordinary fan. At the same time, the air flow is also driven by the viscous force to drive the air forward movement in the circular ring. The results of the superposition of the two effects can theoretically make the actual amount of air flow through the base air volume of 15 times!
