Description

Technical Field

[0001] The utility model relates to the technical field of sterilizers, in particular to a superoxidized air sterilizer. Background Art

[0002] Air is the main transmission medium for respiratory virus infection. The correct use of air disinfection machines can effectively improve air quality and reduce the incidence rate. Ozone, as a highly oxidizing and efficient disinfectant, has the characteristics of thorough and rapid sterilization and is not easily affected by the outside world, making ozone air disinfection machines one of the most common disinfection products. In actual use, if the ozone disinfection machines on the market want to achieve good results, there are certain requirements for ozone concentration, retention time, and relative humidity. However, if the indoor ozone concentration is too high, it will affect human health. Healthy people are at 320μg / m 3 Being in an ozone environment for 1 hour will cause coughing, breathing difficulties and decreased lung function. Therefore, the use of ozone disinfection machines requires separation of humans and machines, and operators can only enter after at least 30 minutes of disinfection. At the same time, due to the strong oxidizing property of ozone, it is corrosive to common items such as metals, rubber, and fabrics. These have limited the scope of use and efficiency of ozone air disinfection machines. Utility Model Content
