We have proposed water purifiers that have sterilization and disinfection functions for single-person households or raise children, not water purifiers used in many homes. It is mainly used to sterilize and disinfect hygiene-sensitive products such as baby bottles, tumblers, and cups. The operation panel is set in the middle of the two functional parts to enable organic use so that the water purification part, sterilization, and disinfection parts can be used together. It is a product that provides a hygienic living culture to users through two functions.
