Description

UV Sterilizer Combination Structure}

The present invention relates to a UV sterilization device combination structure that selectively sterilizes objects outside or inside a storage box according to the user's selection, but can especially ensure the safety of infants when sterilizing in the storage box.

According to recent experimental results by researchers at Hong Kong's South China Morning Post (SCMP), the COVID-19 virus can survive for 3 hours on paper and tissue, 2 days on surface-treated wood and raw materials, up to 4 days on glass and banknotes, and up to 4 days on stainless steel and plastic. It is said that it can survive on the surface for up to 7 days.

The results of this study show that we must be as careful about infections caused by viruses remaining on household items as we are about infections caused by human-to-human contact.

In particular, children in the oral stage touch many types of toys with their hands and put them in their mouths, so they need to pay as much attention to care and hygiene as they do eating utensils and baby bottles.

Parents raising children at this age either take the trouble of collecting toys each time, washing them, and wiping them with sanitary tissues, or they give up hygiene management altogether.

Furthermore, in communal living spaces where many children live together, such as kindergartens and daycare centers, many children are exposed to various viruses such as hand, foot, and mouth, enteritis, and flu. To prevent infection by these viruses, boil them at high temperature, use chemicals, or use ultraviolet rays. Sterilization is carried out by .

Among these conventional sterilization methods, sterilization with chemicals causes secondary risks by leaving harmful chemicals on the surface, and sterilization with heat can cause safety problems due to high heat.

In addition, the sterilization method by boiling causes deformation and damage of the product and has the disadvantage of safety accidents such as burns, so it is a method that has been used in recent years.

Therefore, recent sterilizers have used ultraviolet UV LED as a sterilization source. Although ultraviolet UV LED has a certain sterilizing power, there is a great risk of exposure to heavy metals such as mercury if the lamp is damaged.

Recently, UV LED has emerged as an alternative to UV LED. UV LED has become a sterilization source in the spotlight in the sterilization market as an eco-friendly technology that guarantees reliable sterilization without the risk of damage or exposure to heavy metals.

However, UV LED cannot ignore the problem of harm to the human body due to exposure to ultraviolet rays, so some companies indiscriminately sell products on the market that do not clearly specify the risks of exposure to ultraviolet rays and do not even properly comply with safety devices and standards. And the systems and solutions that can solve these problems are still lacking.
