AI Technical Summary
In existing technologies, it is difficult to completely remove dirt from the inner wall near the sealing water level of bathroom drainage devices, leading to the proliferation of bacteria and mold.
Using an ultrasonic oscillator and sterilization device, the inner wall of the sealing water forming part is cleaned by ultrasonic waves. Then, sterilization water or sterilization gas is used to inhibit the growth of bacteria and mold. The water level and the usage time of the sterilization agent are controlled by the water level riser and control unit.
It effectively removes dirt from the inner walls near the water seal level, inhibits the growth of bacteria and mold, and keeps the bathroom walls clean.
