[0030] The total height of the box body 1 is 2.4 meters, the height of the open hole 101 is 1.8 meters, and the vertical height of the inner groove body 4 is 25 centimeters.
[0031] The outside of the box body 1 is connected with the wall through a waterproof plate to form a separation between indoor and outdoor, and when entering the production workshop, it is necessary to pass through the box body 1.
[0032] The inside of the box body 1 is divided into a primary purification pool and a secondary purification pool, the purpose of the primary purification pool is to remove dust particles attached to shoes, and the purpose of the secondary purification pool is to perform atomizing and spraying disinfection.
[0033] One end of the water inlet main pipe 6 is closed, and the other end is connected with a booster pump, and disinfectant is pumped through the booster pump.
[0034] When a person enters the production workshop, first, the person changes into a dust-free suit outdoors, then walks into the primary purification pool, stands in the primary purification pool for 10-20 seconds, then pulls open the waterproof door curtain 5 and enters the secondary purification pool, and disinfection and sterilization are realized through the atomizing and spraying mode.
[0035] Referring to Figure 1 and Figure 2As shown, the preliminary purification tank 42 has an inclined bottom surface 421, the depth of the bottom surface 421 gradually increases away from the partition 41, the surface of the bottom surface 421 is uniformly distributed with friction particles 422, the partition 41 is hollow inside, the side of the partition 41 facing the preliminary purification tank 42 is provided with a plurality of spray heads 423, the spray heads 423 spray towards the bottom surface 421, the first water outlet pipe 121 corresponds to the low position of the bottom surface 421, so that the water sprayed from the spray heads 423 is discharged from the first water outlet pipe 121, and the preliminary purification tank 42 is kept free of water accumulation, and a water inlet pipe 424 is installed outside the box 1 and communicates with the partition 41.
[0036] In the above technical solution, the inclined bottom surface 421 is adopted, which facilitates the discharge of particles washed from the shoe sole and avoids water accumulation above the bottom surface 421.
[0037] The water pump is connected to the water inlet pipe 424, and after the water pump extracts pure water, the water is sprayed from the spray heads 423, which spray towards the bottom surface 421 to flush away the particles deposited on the bottom surface 421.
[0038] Referring to Figure 2 As shown, the friction particles 422 are semispherical or cylindrical, and the height of the friction particles 422 protruding from the bottom surface 421 is 8-12 mm.

[0040] Referring to Figure 2 As shown, the inclination angle of the bottom surface 421 is 3-6°.
[0041] In this embodiment, the inclination angle of the bottom surface 421 is 5°.
[0042] Referring to Figure 1 As shown, the bottom of the box 1 is penetrated, the inner groove body 4 is loaded from the bottom of the box 1, and the contact position between the inner groove body 4 and the box 1 is glued to form a seal.
[0043] The above technical solution facilitates the assembly of the inner groove body 4.
[0044] Referring to Figure 2 As shown, the lower end of the waterproof curtain 5 hangs into the secondary purification tank 43.
[0045] The above structure allows the atomized water vapor sprayed from the atomizing spray head to drip along the waterproof curtain 5 into the secondary purification tank 43 after being attached to the waterproof curtain 5, thereby achieving the collection of the disinfectant.
[0046] Referring to Figure 1 As shown, the height of the second water outlet pipe 131 is higher than the bottom of the secondary purification tank 43, specifically 4cm higher, so that the secondary purification tank 43 retains disinfectant liquid.
[0047] By retaining part of the disinfectant liquid in the secondary purification tank 43, the shoe soles can be soaked for disinfection.
[0048] Referring to Figure 1 As shown, a sealing ring 199 is installed at the edge of the opening 101, and the box door 3 contacts the sealing ring 199.
[0049] The sealing ring 199 can increase the sealing property.
