In order to prevent the dust and germs carried on the body surface of people entering and leaving the area and causing pollution to the interior of the area, corresponding isolation doors are often installed at the entrance and exit of the area to spray or kill the dust and germs on the body surface of people entering and leaving the area.

[0003] According to the patent CN214740889U, a laboratory clean sterilization isolation door comprises a first isolation door, a second isolation door and a controller arranged in parallel, a porch is provided between the first isolation door and the second isolation door, the first isolation door, the porch and the second isolation door form a sealed clean sterilization space, a spray sterilization mechanism and a ventilation mechanism are provided inside the porch; an air cleanliness tester is provided in the porch, the first isolation door comprises a door frame, a sensing door is provided on the door frame, a roller brush is provided on one side of the door frame connected to the porch corresponding to the sensing door, a dustproof door curtain is provided between the roller brush and the porch, and the sensing door and the air cleanliness tester are both electrically connected to the controller. The utility model has a good sterilization effect and can effectively isolate the flow of external environmental air and the internal air of the laboratory. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. By arranging corresponding roller brushes and spraying sterilization mechanisms inside the isolation door, the floating dust and bacteria adhered to the body surface of the people entering and leaving are avoided to prevent the bacteria carried on the body surface of the people from polluting the interior of the area. In actual use, the spraying sterilization mechanism is only arranged inside the porch to atomize and spray the disinfectant used for sterilization and cleaning to the outside of the people's body, and when spraying it, only The spray pipe can be used to clean and sterilize the left and right sides of the body of the person entering and leaving, but the disinfectant cannot quickly and directly contact the front and back sides of the person, which can easily cause the person to cause bacteria contamination inside the area.

[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0028] Example 1: A clean laboratory sterilization isolation door, see Figures 1 to 5A fixed frame 16 is fixedly installed on the inner side of the porch frame 1, a transmission frame 25 is fixedly installed on the outer top middle surface of the porch frame 1, a hollow rotating frame 2 is rotatably installed on the inner side of the fixed frame 16, and hollow storage frames 21 are horizontally fixedly installed at both ends of the inner bottom of the hollow rotating frame 2, and a movable plate 22 is slidably inserted on the inner side of each hollow storage frame 21, and a cleaning brush plate 23 is fixedly installed on the bottom of each hollow storage frame 21 and the movable plate 22, and a reset spring 5 is movably sleeved inside each hollow storage frame 21, and the reset spring 5 The two ends of the side are respectively fixedly connected to the movable plate 22 and the inner wall of the hollow storage frame 21, and a rotating connecting pipe 26 is vertically penetrated and rotatably installed inside the transmission frame 25 through a bearing. The bottom of the rotating connecting pipe 26 is rotatably installed on the top of the porch frame 1 and the fixed frame 16 through a bearing, and the bottom of the rotating connecting pipe 26 is fixedly connected to the top of the hollow rotating frame 2, and the top of the rotating connecting pipe 26 is fixedly connected to a rotating joint 27, and the other side of the rotating joint 27 is fixedly connected to the conveying elbow 13, and the bottom of the inner bottom of the transmission frame 25 is fixedly installed The servo motor 15 is provided with a transmission gear 29 fixedly sleeved on the top of the transmission shaft of the servo motor 15, and a follower gear 28 is fixedly sleeved on the middle end surface of the outer side of the rotating connecting tube 26, and the outer side of the transmission gear 29 is meshed with the outer side of the follower gear 28. Through the meshing transmission action of the transmission gear 29 and the follower gear 28, and the rotation connection action of the rotating joint 27, the servo motor 15 can drive the hollow rotating frame 2 to rotate synchronously when it is running, so that the spray port 24 can perform circular rotation spraying on the outer side of the body of the person entering and leaving, and the disinfectant is evenly sprayed from different directions to the outer side of the body of the person entering and leaving for spraying and disinfection. At the same time, combined with the pushing action of the reset spring 5 on the movable plate 22, after the person entering and leaving moves away from the surface of the standing plate 11, the cleaning brush plate 23 can be synchronously moved to fit the standing plate 11 and perform rotation and brushing cleaning on its surface, thereby improving the killing and cleaning quality of dust and bacteria on the surface of the body of the person entering and leaving, and avoiding pollution to the clean area behind the porch frame 1 and affecting the experimental use.

[0029] For details, see Figures 1 to 5 A liquid storage frame 12 is fixedly installed at the bottom of the outer side of the porch frame 1, and the bottom of the delivery elbow 13 is fixedly connected to the top of the liquid storage frame 12. A liquid extraction pump 14 is fixedly connected to the outer side of the delivery elbow 13. Through the structural function of the liquid extraction pump 14, the disinfectant inside the liquid storage frame 12 can be extracted and transported.

[0030] For further information, see Figures 1 to 5 A standing board 11 is fixedly embedded in the middle of the inner bottom of the porch frame 1, and a hollow storage frame 21 and a movable board 22 are located on both sides of the top surface of the standing board 11. The setting of the standing board 11 facilitates the fixing of the standing position of people entering and leaving, thereby facilitating the subsequent sterilization and cleaning of the outside of the body of people entering and leaving.

[0031] It is worth noting that see Figures 1 to 5 Spray ports 24 are provided at both ends of the inner side of the hollow rotating frame 2, and the number of the spray ports 24 is several groups. By providing multiple groups of spray ports 24, the discharge and delivery range of the disinfectant liquid is increased, thereby increasing the sterilization and cleaning area.

[0032] It is worth noting that see Figures 1 to 5 , the outer end surfaces of the hollow rotating frame 2 are fixedly installed with mounting frames 3, and the middle end of each mounting frame 3 is screwed with an adjusting bolt 31 through a thread, and a connecting plate 32 is rotatably installed on the side of each adjusting bolt 31 through a bearing, and the connecting plate 32 is slidably installed on the inner side of the mounting frame 3, and a transmission rod 33 is fixedly installed on the two end surfaces of the side of each connecting plate 32 away from the adjusting bolt 31, and a transmission frame 34 is slidably installed on the inner end of the hollow rotating frame 2, and the side of the transmission frame 34 is fixedly connected to the outer side of the transmission rod 33, and a sealing baffle 35 is fixedly installed on the side of each transmission frame 34, and the sealing baffle 35 is slidably inserted into the inside of the spray tank, and the screwing adjustment effect of the adjusting bolt 31 on the transmission plate and the transmission frame 34 can adjust the shielding area of ​​the sealing baffle 35 inside the spray tank, and then the discharge amount of the spray disinfectant can be adjusted according to the body cleanliness of the people entering and leaving, so as to avoid waste caused by excessive spraying of disinfectant or insufficient spraying to affect the sterilization and cleaning quality of the body surface.

[0033] It is worth mentioning that see Figures 1 to 5 Guide blocks 41 are fixedly installed on the surfaces of both ends of the side edges of each movable plate 22, and guide grooves 4 are opened on both sides of the interior of each hollow storage frame 21, and the guide blocks 41 are slidably inserted into the interior of the guide grooves 4. Under the guiding sliding action of the guide grooves 4 on the guide blocks 41, when the return spring 5 pushes the movable plate 22, the movable plate 22 can only move horizontally inside the hollow storage frame 21 without lateral movement, thereby ensuring that the movable plate 22 can be moved to the surface of the standing plate 11 and then cleaned and brushed.

[0034] During operation, when a person needs to pass through the porch frame 1 and enter the clean area behind it, the person's feet push the movable plate 22 so that when the person stands on the surface of the standing plate 11, the two sets of movable plates 22 are pushed to move horizontally relative to each other inside the hollow storage frame 21. Then, according to the cleanliness of the outer surface of the person, when it is relatively clean, the adjusting bolt 31 is screwed to drive the connecting plate 32 to move horizontally inside the installation frame 3, and then the sealing baffle 3 can be driven by the transmission rod 33 and the transmission frame 34. 5 then moves synchronously inside the spray port 24 to reduce the open area of ​​the spray port 24. When the cleanliness level of the outer surface of the body is low, the adjusting bolt 31 is turned in the opposite direction to increase the open area of ​​the spray port 24. Then, the liquid pump 14 and the servo motor 15 are turned on through the external control switch. Under the pumping action of the liquid pump 14, the disinfectant is drawn out from the liquid storage frame 12 and transported to the inside of the delivery elbow 13. After being atomized by the atomizing mechanism connected to the side of the delivery elbow 13, the disinfectant is synchronously transported to the rotating connection 27 through the rotary joint 27. The liquid is then transported to the inside of the hollow rotating frame 2 and discharged through the spray port 24. Then, under the operation of the servo motor 15, the transmission gear 29 can be driven to rotate synchronously inside the installation frame 3. Combined with the meshing transmission of the transmission gear 29 and the follower gear 28, the rotating connecting pipe 26 and the hollow rotating frame 2 below it can be driven to rotate accordingly, so that the hollow rotating frame 2 and the spray port 24 can rotate in a circle when people enter and exit, and the atomized sterilizing liquid discharged from the spray port 24 can be evenly sprayed on the people. The outside of the body of the people entering and leaving is fully sterilized and cleaned at different positions on the outside of the body. After the cleaning is completed, the people entering and leaving can enter and exit the clean area through the porch frame 1. After the movable plate 22 loses its resistance force, the movable plate 22 can be driven to restore its position under the reverse push of the reset spring 5. Combined with the rotation of the hollow rotating frame 2, the hollow storage frame 21 and the cleaning brush plate 23 at the bottom of the movable plate 22 are driven to rotate synchronously, and the surface of the standing board 11 is brushed and cleaned, thereby improving the cleanliness of the inside of the porch frame 1.
