AI Technical Summary

Technical Problem

In existing technologies, multi-stage ion wind acceleration structures pose risks of fire, have difficulty controlling ozone production, and pose safety hazards due to the need for high DC voltage at high wind speeds. Furthermore, pure DC power supplies have low air ionization efficiency.

Method used

By using a hybrid connection of DC and AC power supplies, and through the cooperation of voltage divider circuits and capacitors, the voltage difference between adjacent ion wind acceleration structures is achieved, breaking through the ignition voltage limit, increasing the wind speed, and realizing multiple working modes by adjusting voltage parameters.

Benefits of technology

It improves air ionization efficiency, increases wind speed, reduces the risk of fire, reduces ozone production, and enables switching between multiple working modes, thus improving safety and energy efficiency.
