[0073] 1. The timer module 38 sets the interval time in advance. After the controller module 37 receives the feedback information, the timer module 38 is triggered to start timing. After the interval time is reached, the controller module 37 sends a control instruction to the motor driver module 39;

[0074] Exemplarily, the timer module 38 is preset with seconds as the interval time. After the controller module 37 receives the feedback information, the timer module 38 starts counting seconds, and then the controller module 37 sends a control instruction to the motor driver module 39 .

[0075] 2. After receiving the control instruction from the controller module 37, the motor driver module 39 converts it into a physical signal executable by the motor, and controls the servo motor 32 to rotate according to the number of turns set by the motor driver module 39;

[0076] Exemplarily, the motor driver module 39 sets the servo motor 32 to rotate one circle, and the corresponding rotating cavity 19 drives the three straight-through tubes 21 to rotate one and a half circles.

[0077] S2, the entrance passage 14 starts to disinfect the employees, the blowing duct 16 injects dry hot air toward the entrance passage 14 through the air injection slot 35, and the exhaust duct 17 extracts moist air toward the inner side of the entrance passage 14 through the slot 20, so as to achieve the effect of drying the whole body of the personnel;

[0081] When the humidity detected by the inlet passage 14 is lower than the set threshold, the blowing duct 16 and the exhaust duct 17 stop working, and the controller module 37 controls the induction lamp 25 in the response module 40 to switch from red light to green light.

First, the employees need to stand on the top of the wire mesh disc 31. The wire mesh disc 31 drives the semicircular cover 28 to slide vertically downward until the semicircular cover 28 and the circular platform 26 are closed into a closed cavity. The sealing ring 30 strengthens the sealing between the semicircular cover 28 and the circular platform 26, and tries to avoid the mist of the disinfectant from eroding the pressure sensor 27, thereby increasing the service life of the pressure sensor 27.

[0087] After the pressure sensor 27 senses the pressure, it will drive the servo motor 32 to rotate through the controller module 37 and the motor driver module 39. The servo motor 32 drives the rotating cavity 19 to rotate two and a half circles through the gear 33 and the ring gear 34. While the rotating cavity 19 rotates, several nozzles 22 on the side of the straight pipe 21 spray disinfectant mist toward the employees. The arc cover 23 that rotates two and a half circles can isolate the employees from the outside world. The employees are between the arc cover 23 and the door curtain of the clean room 11. After the employee disinfection is completed, the blowing duct 16 injects dry hot air toward the entrance channel 14, and the exhaust duct 17 draws humid gas toward the inside of the entrance channel 14, so as to achieve the effect of drying the inside of the entrance channel 14 and the body of the personnel.

[0088] When the personnel leaves the top of the wire mesh disc 31, the pressure sensor 27 senses that the pressure disappears, and drives the servo motor 32 to reset through the controller module 37 and the motor driver module 39. At this time, the personnel can enter the clean room 11 to work.
