when the number of the disinfectant spraying mechanisms exceeds a set value, the PLC controller timely controls the disinfectant spraying mechanism 42 to work, liquid is supplied to the atomizing spray head 422 through the annular water pipe 421 in the disinfectant spraying mechanism 42, and atomized alcohol is sprayed through the atomizing spray head 422 to disinfect the shoes of a user; since the groove 431 is formed on the lifting pressure-bearing plate 43, the mist alcohol can disinfect the sole of the user through the groove 431;

after the two shoes are sterilized, the plastic film used as a shoe cover is laid on the top end of the heating copper plate 341 embedded on the second step box 12 through the feeding assembly 20, the user aligns the sterilized sole with the heating copper plate 341 and presses the heating copper plate 341 again by means of self weight, and the pressure sensor 4134 in the first damping lifting mechanism 33 is enabled to transmit an electric signal with pressure to the receiver of the PLC controller and then the PLC controller is used for judging whether the pressure exceeds a set value or not because the first damping lifting mechanism 33 and the second damping lifting mechanism 41 have the same structure;

when the air quantity exceeds the set value, the PLC controller timely controls the heat sealing mechanism 32 to start working, and the hot air blown out from the air outlet pipe 324 in the heat sealing mechanism 32 heats the plastic film serving as the shoe cover, so that the plastic film is attached to the shoes of the user to form the shoe cover; in the process, the bottom of the shoe cover is heated by the heating copper plate 341 so that the plastic film is further attached to the anti-skid of the shoe cover of a user, the friction force between the plastic film and the ground is increased, and the anti-skid patterns of the shoe cover are further manufactured by heating the convex beads 342 on the copper plate 341.
