Currently, airborne transmission is an important mode of transmission of viruses. Airborne transmission refers to the entire process of air invasion into a new susceptible host after the pathogen has been expelled from the source of infection.
The novel coronavirus pneumonia is an acute infectious pneumonia, and the pathogen thereof is a novel coronavirus which is not found in human before. The transmission of coronaviruses via respiratory droplets and intimate contact is the main transmission route.

However, in the closed space formed by the bracket of the air sterilizer, the temperature of the bracket of the air sterilizer is high, the bracket of the air sterilizer with the high temperature easily affects the temperature sensing bulb, and further the final temperature detection of the temperature sensing bulb is inaccurate, and the accuracy judgment is wrong.
