Background technique

In modern urban life, people have higher requirements for personal hygiene and family hygiene. Personal daily objects, such as the surface of mobile phones, can easily carry a large number of bacteria and viruses. For example, on cardboard, viruses can survive for up to 24 hours, except for the surface of personal objects. In addition to sterilization and disinfection, people have higher and higher requirements for air quality in personal household living spaces, and indoor air needs to be sterilized and disinfected. Aerosols (such as PM2.5 dust) are important carriers of airborne bacteria and viruses, such as influenza virus, The new coronavirus can survive in air aerosols for up to 3 hours. Therefore, it is more urgent to sterilize items and indoor air at the same time. In the existing technology, ultraviolet sterilization products usually have a single function, which needs to meet the requirements of sterilization of personal objects and indoor air. For these two requirements, users can only purchase products with different functions, and the disinfection process is relatively simple, and there is insufficient disinfection. Holes, increase the air flow in the disinfection cavity, so as to facilitate the rapid drying of dishes, tableware and other items, but the tray used for placing the dishes and tableware on the one hand blocks the irradiation of ultraviolet rays, which is not conducive to the disinfection of the bottom of the dishes and tableware.
