What is the principle of bladeless fan and how the wind is formed.

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.

It produces the same amount of air as the best fan on the market. 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!

Extended data:

In the production process, compared with the traditional fan, the fanless electric fan mainly increases the design, manufacture and assembly links of the inner cavity of the air outlet frame, and the cost increase is not obvious. Especially after forming a certain scale assembly line, there is no need to worry about the high price caused by the scarcity of raw materials, which will not increase the manufacturing difficulty due to the complicated process, and will not reduce the product quality due to the change of structural design.

The structure of the bladeless fan is a touch tilt with its own gravity as the center fulcrum, and the angle of the fan can be changed by pressing it with your hand; Therefore, the bladeless fan is superior to the traditional vane fan in many aspects.

1, safety: traditional fans use blades to cut the wind, which is easy to cut children's fingers and hide certain dangers. The bladeless fan has no blade rotation, high safety factor and no danger.

2, environmental protection: imported ABS materials, passed the Rohs environmental protection certification.

3. Health: The bladeless fan is optimized by air multiplication technology, and natural wind blows in front of human body 100%. Especially for pregnant women, it is easy to get sick when the air conditioner is turned on in hot weather, and the fanless electric fan has good protection for pregnant women and babies! But also has a good health care function for the elderly and children. (It involves cheating consumers. Excessive negative oxygen ions are harmful to human body. Although negative oxygen ions are harmful to human body, the advantages outweigh the disadvantages. Generally, as long as you don't stay in a place full of negative oxygen ions all day, it won't have much impact])
