In public places, people often touch the door handle. The virus is very likely to spread through the door handle and hands. This is extremely dangerous when public health incidents such as infectious diseases erupt, which is fully illustrated by COVID-19 in 2020. Lanzin is an electronic atomization sterilizer mounted on the door handle. When the ultrasonic sensor detects that the human hand is 2 seconds after contacting and leaving, it will automatically spray out the atomized disinfectant. Lazin can be used in hospitals, shopping malls, teaching buildings and offices, etc. It plays a small and critical role in epidemic prevention & control.
