Solution Approach 1:

The patent replaces the mechanical filtration system (HEPA filter net that physically blocks particles) with an electrostatic field system (first and second annular rings generating electric fields). This substitution eliminates the need for high-resistance mechanical filters, thereby reducing electricity consumption and noise while maintaining dust removal efficiency through electrostatic attraction of charged particles.
