Firstly, the air supply component 4 is put into the shoe, the shoe 1 is wrapped by the rubber shoe cover 2, then the self-locking plastic button 11 is used for tightly connecting the rubber shoe cover 2 with the device joint 10, so that the space in the shoe and the device form a closed space, and the preparation work before the device operates is made. And then the switch of the fan 5 and the ozone generator 8 is turned on to start the sterilization and disinfection mode of the device, the device runs for a proper time, and the switch of the ozone generator 8 is turned off after the sterilization and disinfection work in the shoes is finished.
