Through the cooperation between the filter plate 3, the blower box 7, the blower 8, the negative pressure regulating component and the exhaust fan 13, not only is efficient filtration of the air entering the operating room 10 achieved, but also the effect of precise monitoring and regulation of the negative pressure in the operating room 10 is achieved.

[0028] Specifically, the display screen 11 is used to display the current negative pressure status in the operating room 10, and controls the opening or closing of the exhaust fan 13 through the differential pressure sensor 12 to achieve the effect of exhausting the air in the operating room 10.
[0029] Reference Figures 1-3 Fiberglass board 4 is made of fiberglass; silicone board 5 is made of silicone rubber; polypropylene microfiber board 6 is made of polypropylene fiber.
[0030] Specifically, the fiberglass board 4 is used to filter large particulate impurities in the air, the silicone board 5 has good toughness and sound insulation and noise reduction performance, which can not only improve the overall toughness and strength of the filter board 3, but also reduce the noise generated by the bellows equipment during operation. The polypropylene microfiber board 6 can efficiently filter tiny impurities and bacteria in the outside air. Through the cooperation between the fiberglass board 4, silicone board 5 and polypropylene microfiber board 6, not only is the overall strength of the filter board 3 improved, but the outside air can also be efficiently filtered, thus improving the air quality delivered to the operating room 10.
[0031] Reference Figure 2 , Figure 4 and Figure 5 The outer wall of the outdoor unit 1 is fixedly connected to a housing 15. A limit assembly is installed inside the housing 15. A spring 18 is installed on the outer wall of the limit assembly, and the outer wall of the spring 18 is located inside the housing 15. A connecting plate 20 is slidably connected to the outer wall of the limit assembly. The outer wall of the connecting plate 20 is fixedly connected to the outer wall of the outdoor unit 1. A rotating plate 21 is installed on the outer wall of the connecting plate 20. A support assembly is installed inside the rotating plate 21, and the outer wall of the support assembly is fixedly connected to the outer wall of the protective plate 2. The limit assembly includes a sliding column 16, the outer wall of which is slidably connected to the inside of the housing 15. A connecting column 17 is fixedly connected to the outer wall of the sliding column 16, and the outer wall of the connecting column 17 is slidably connected to the inside of the outer shell 15. The outer wall of the spring 18 is disposed on the outer wall of the sliding column 16, and the outer wall of the sliding column 16 is slidably connected to the inside of the connecting plate 20. The support assembly includes a support column 22, the inside of the rotating plate 21 is rotatably connected to the outer wall of the support column 22, a support plate 23 is fixedly connected to the outer wall of the support column 22, the outer wall of the support plate 23 is fixedly connected to the outer wall of the protective plate 2, and a sliding groove 19 is provided inside the outer shell 15. The connecting column 17 is slidably connected to the inside of the outer shell 15 through the sliding groove 19.
[0032] Specifically, firstly, the sliding connecting column 17 moves. When the connecting column 17 moves, the sliding column 16 will move due to the fixing effect of the connecting column 17 and the sliding column 16. The spring 18 is used to reset the sliding column 16. After the connecting column 17 moves to the appropriate position, the connecting column 17 is rotated to fix it inside the outer shell 15. Then, the rotating plate 21 is flipped. By rotating the rotating plate 21, the protective plate 2 can be quickly disassembled, which facilitates the maintenance and repair of the bellows equipment in the future.
[0033] Working principle: Since the fiberglass board 4 is made of fiberglass, which not only has good high temperature resistance and chemical stability, but also can filter small and medium-sized particulate impurities in the air to a certain extent, the silicone board 5 has good toughness and sound absorption, which can not only improve the overall strength of the filter board 3, but also reduce the noise generated by the air box equipment during operation, providing a quiet environment for medical and nursing care. The filtered air is delivered to the operating room 10 by the blower 8. The display screen 11 and the differential pressure sensor 12 work together to monitor and adjust the negative pressure of the operating room 10. When it is necessary to remove the air in the operating room 10, the display screen 11 issues a command, and then the differential pressure sensor 12 controls the exhaust fan 13 to start, so that the air in the operating room 10 is discharged through the exhaust duct 14, thereby achieving the effect of efficiently filtering the air delivered to the operating room 10 while also adjusting the negative pressure in the operating room 10.
[0034] First, slide the connecting column 17 upwards. When the connecting column 17 moves, it will drive the sliding column 16 to slide inside the outer shell 15. At the same time, it will cooperate with the outer shell 15 to compress the spring 18. When the connecting column 17 slides to the appropriate position, rotate the connecting column 17 so that it is fixed inside the outer shell 15 through the sliding groove 19. At this time, flip the rotating plate 21. The support column 22 and the support plate 23 cooperate to support the rotating plate 21 to flip. By sliding the connecting column 17, the protective plate 2 can be quickly unlocked and disassembled, which reduces the time cost required for maintenance of the bellows equipment in the later stage.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
