[0002] The biggest difference of a bladeless fan is that it does not have the "blades" of a traditional fan. The bladeless fan uses the technology of jet engines and automobile turbochargers to suck air through the air suction hole at the bottom, and an impeller hidden inside the edge of the ring sprays the air in a circular trajectory, eventually forming an uninterrupted air flow. The important thing is that this air flow is smoother than the wind generated by an ordinary fan. The amount of air it produces is equivalent to the best performing fan on the market. However, the existing bladeless fans have a relatively single function and can only play a role in blowing air. In the case of high temperatures in summer, the cooling effect is effective and cannot meet the user's needs.
