Modern people's awareness of personal hygiene and health is gradually increasing, and it is imperative to find a tool that can instantly sterilize the items that will be touched. For example, in the case of edible containers such as cups or bowls, most of the users use detergents and clean water to remove oily or crumbs from the used cups or lunch boxes, but the above cleaning methods cannot kill bacteria that are not easily perceived by the naked eye. Or microorganisms.

At present, the sterilization ability of ultraviolet light has been confirmed. Therefore, related manufacturers have developed a sterilization box using ultraviolet light as a sterilization light source, so that users can put small household items into it for sterilization.
