The kill task is then initiated by releasing and depressing the safety trigger 140 again. When the sterilizing device continuously works and the time required for sterilization is reached, the sterilizing device sends out prompt sound again to indicate that the sterilization task is finished. In the process of disinfection, if an emergency is encountered, the user can timely loosen the safety trigger 140, the disinfection device stops working, and timely responds to the emergency.

When the manual mode, that is, the non-automatic mode is selected, the user can set the sterilizing power and the sterilizing time of the sterilizing device by giving instructions to the buttons around the LCD display screen 161.
