Description

Sterilization cleaning device that performs sterilization, disinfection, cleaning and drying functions for everyday objects

The present invention relates to a sterilization cleaning device, and more particularly, to a sterilization cleaning device that performs sterilization, disinfection, cleaning, and drying functions for everyday objects such as toys, dolls, mobile phones, and glasses.

When using everyday items such as smartphones, we are exposed to various pollutants. Many germs, bacteria, viruses, etc. are detected in objects exposed to these contaminants. Since germs, etc. are invisible to the naked eye, users use the object without any objection, eat food without washing their hands after use, or touch their eyes, nose, mouth, etc., providing a good route for germs to invade the human body. will do

As the spread of various infectious diseases (COVID-19, etc.) has recently become clear, people are making various efforts to sterilize and disinfect objects (smartphones, wireless earphones, glasses, watches, accessories, dolls, toys, etc.) that are used closely to the human body. It is being done.

Thanks to these efforts, various products for sterilizing smartphones and the like have been introduced, and many devices using a sterilization method using ultraviolet rays have been introduced. In a method of emitting ultraviolet rays, UV-LED is used to emit ultraviolet rays of a specific wavelength, and then irradiated to objects for a predetermined period of time to sterilize them.

The ultraviolet sterilization method is mainly used for objects that cannot be used with water or alcohol. In particular, since it is limitedly used for items vulnerable to moisture such as smartphones, wireless earphones, and portable batteries, the use of the sterilization device is limited to these items.

However, in daily life, you have to use various types of things other than smartphones, wireless earphones, and portable batteries, and if you adopt and use different types of sterilization devices for each item, it is not economical because you have to purchase and use too many types of equipment.

In order to integrate these sterilization devices into one equipment, it is necessary to develop a new type of sterilization and disinfection device that can selectively use sterilization and disinfection methods according to the situation in consideration of the characteristics of objects that are vulnerable to moisture and objects that are resistant to moisture. It is required.

Titanium dioxide is a type of semiconductor, and when a certain amount of energy is applied to the semiconductor, the electrons staying in the valence band receive energy and move to the conduction band, where they can move freely out of the bondage of the atomic nucleus. Light (ultraviolet rays) serves as energy for electrons to move. Negatively charged electrons (e-) stay in the conduction band of titanium dioxide, and positively charged holes (h+) are created in the valence band of titanium dioxide.

At this time, electrons cause a reduction reaction with oxygen to create superoxide (O2-), and holes cause an oxidation reaction with water to generate active oxygen called hydroxyl radical (OH-). Superoxide and hydroxyl radicals are substances with strong energy and can be used to easily decompose volatile organic compounds and various odor-causing substances. In addition, it can remove BOD, non-degradable pollutants, and environmental hormones from various wastewater. In addition, it can oxidize and remove target substances, such as sterilizing over 99% of various pathogens and bacteria such as pathogenic Escherichia coli, Staphylococcus aureus, and O-157.
