[0041] It should be noted that, in the present embodiment, during ventilation, air enters the room through the air exchange hole 41, and the filter 42 filters the air. When epidemic prevention protection is required, the controller triggers the gas source system connected to the gas pipe 432, and the pressurized gas enters the annular air bag 431 through the gas pipe 432. The annular air bag 431 expands to urgently seal the connecting hole 412, and then the second micro motor 444 drives the driving gear 445 to rotate, and the driving gear 445 drives the opening and closing plate 442 to move up through the rack 443, and the opening and closing plate 442 blocks the air exchange hole 41;
[0042] Furthermore, when the liquid mist disinfection component 35 is disinfected, the air exchange hole 41 can also be disinfected.
[0043] Please refer to the attached Figure 3 , 5 As shown in Figures 7 and 7, in another preferred embodiment of the present invention, a door opening disinfection device 50 is embedded in the entrance door body 10 and located at one end away from the lifting slider 33. The door opening disinfection device 50 includes a disinfection tube 51 embedded in the entrance door body 10 and vertically arranged, a plurality of spray heads 52 connected to the outer wall of the entrance door body 10 at one end and connected to the disinfection tube 51 at the other end, and a second infusion tube 53 connected to the disinfection tube 51 at one end and connected to the first infusion tube 352 at the other end. A second micro solenoid valve 54 is provided on the outer wall of the second infusion tube 53 and located on the side of the entrance door body 10 close to the ventilation opening and closing component 44.
[0044] It should be noted that, in this embodiment, when the door is opened for disinfection, the controller triggers the disinfection liquid source set in the room and opens the second micro solenoid valve 54. The disinfection liquid is sprayed out through the second infusion tube 53, the disinfection tube 51 and the spray head 52 to form a disinfection spray when the door is opened for epidemic prevention.
[0045] The specific process of the present invention is as follows:
[0046] The controller model is "LY2NE-24T-HMI70".
[0047] The owner can unlock the entrance door body 10 through the password lock 211 or the face recognition camera 213 to enter the room. The controller receives the thermal imaging image of the infrared thermal imaging camera 221 and performs epidemic prevention protection when a visitor with a body temperature higher than the normal value is detected;
[0048] When the door disinfection device 30 performs epidemic prevention protection, the controller triggers the disinfection liquid source set in the room and opens the first micro solenoid valve 354. At this time, the disinfection liquid is sprayed out after passing through the first infusion tube 352, the folding hose 351 and the spray tube 353 to perform disinfection. The driving component 34 drives the lifting slider 33 to move downward to disinfect the entire entrance door body 10;
[0049] When the driving component 34 is working, the actuator end of the first micro motor 341 drives the screw rod 342 to rotate, and the screw rod 342 drives the lifting slider 33 to move up and down;
[0050] When the lifting slider 33 moves, the cleaning brush 361 moves under the drive of the lifting slider 33 to clean the liquid attached to the main body 10 of the entrance door after disinfection, and the liquid finally falls into the receiving box 362;
[0051] During ventilation, air enters the room through the air exchange hole 41, and the filter 42 filters the air. When epidemic prevention protection is required, the controller triggers the gas source system connected to the gas pipe 432, and the pressurized gas enters the annular air bag 431 through the gas pipe 432. The annular air bag 431 expands to urgently seal the connecting hole 412. Then the second micro motor 444 drives the driving gear 445 to rotate, and the driving gear 445 drives the opening and closing plate 442 to move up through the rack 443, and the opening and closing plate 442 blocks the air exchange hole 41.
[0052] When the liquid mist disinfection component 35 is disinfected, the air exchange hole 41 can also be disinfected;
[0053] When the door is opened for disinfection, the controller triggers the disinfection liquid source set in the room and opens the second micro solenoid valve 54. The disinfection liquid is sprayed out through the second infusion tube 53, the disinfection tube 51 and the spray head 52 to form a disinfection spray when the door is opened for epidemic prevention.
[0054] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
