Description

technical field [0001] The invention belongs to the technical field of sterilization and disinfection, and relates to an ozone generating device. Background technique [0002] At present, various small containers such as refrigerators, freezers, food cabinets, tea cabinets, and fruit storage cabinets often produce serious odors due to the growth and reproduction of bacteria and molds when storing food or other items, and pollute tableware and utensils. Wait. Activated carbon is a commonly used deodorant in people's daily life. It mainly deodorizes through physical adsorption; however, activated carbon does not have the function of sterilization and disinfection, and it is difficult to effectively remove bacteria and molds that grow in containers. [0003] Ozone has a strong bactericidal effect and can effectively control mold, bacteria and other hazards; in addition, ozone has strong oxidizing properties and can react with organic phosphorus and nitrate pesticides left in v...
