A Self-Sterilizing Toilet Seat with UVC Radiation

摘要

A toilet set with UVC LEDs radiating 275 nm for sterilization is presented. A visible indication and a proximity detection to warn and protect users from being hurt by the UVC radiation are also included. The sterilization of the toilet seat begins whenever the toilet lid lays down well on the seat. The condition is detected and confirmed by a coordination of a reed switch and a power magnet. The sterilization will last for an expected time, six minutes in a prototype toilet set. If it is interrupted, the proposed safety measures will take over the operation of the sterilization.
