Three control keys 2, a power switch key, a quick disinfection key and a strong disinfection key are arranged in the machine. The control key 2 is welded to the main control board 27 and supported on the surface of the plate-like casing 1 via the main control board 27. When the power switch key is pressed, the main control board 27 is powered on, and when the quick disinfection key is pressed, the main control board is disinfected for 59 seconds, and when the strong disinfection key is pressed, the main control board is disinfected for 180 seconds. It should be noted that the specific sterilization time is only a preferred embodiment, and the time for rapid sterilization and the time for intensive sterilization in the present application are not limited to the specific values.
