[0051] In the above scheme:

[0052] 1. The UV disinfection machine is designed with a top rail style. The main chassis can move along the top rail. In this way, the air intake direction can be changed to realize patrol ventilation of the ICU ward, effectively improve the disinfection and ventilation efficiency, and sufficient disinfection and ventilation can be stopped in each area;

[0053] 2. Designing a UV irradiation component with a multi-section bending structure can achieve the following effects:

[0054] 2.1. During daily air inhalation disinfection operations, the UV irradiation component can be retracted into the main chassis, and the UV irradiation component and the inner guide plate form a serpentine airflow channel, so that the UV lamp can release ultraviolet rays to disinfect the inhaled gas, and increase the gas flow path, so that the air and the UV lamp are fully in contact, effectively improving the disinfection effect;

[0055] 2.2. When no one is in the ward, the side blocking component can be rotated outward to open, thereby bringing out the ultraviolet irradiation component.

[0060] 3.3. When manual disinfection of dead corners is required, the mobile suction component is manually removed and the air inlet pipe is closed. In this way, the negative pressure generated at the air inlet pipe will be transmitted to the mobile suction component. There is no need to configure a fan for the mobile suction component. The mobile suction component can be used to sterilize the area around the bed.

[0061] In this embodiment, the side blocking assembly 7 includes a first driving rod 71, an outward guide rail 72, a first blocking plate 73, a second blocking plate 74, a third blocking plate 75 and a second driving rod 76. One end of the first driving rod 71 is arranged at the top of the main chassis 1, and an external connecting seat 711 is vertically arranged at the output end of the first driving rod 71. The top of the main chassis 1 is symmetrically provided with an outward guide rail 72, and the external connecting seat 711 is slidably arranged between the two groups of outward guide rails 72; one end of the surface of the first blocking plate 73 is symmetrically provided with a connector 731, and the other end is symmetrically provided with a first constraint sleeve 732, and the connector 731 is rotatably connected to the external connector. The seat 711 is provided with a flip control component at the rotating connection, and one end of the second driving rod 76 is arranged on the surface of the first blocking plate 73; the surface of the second blocking plate 74 is symmetrically provided with a first guide rod 741 at one end and a second constraint sleeve 742 at the other end, and one end of the first guide rod 741 is slidably embedded in the first constraint sleeve 732; the surface of the third blocking plate 75 is symmetrically provided with a second guide rod 751 at one end, and the second guide rod 751 is slidably embedded in the second constraint sleeve 742; the output end of the second driving rod 76 is connected to the third blocking plate 75, and the outer ends of the first guide rod 741 and the second guide rod 751 are provided with stop structures.

[0062] In the above scheme: when the side blocking assembly needs to be opened, the first driving rod extends outward, and then pushes out the first blocking plate, the second blocking plate and the third blocking plate at the same time; when the first blocking plate moves to the outer end of the outward guide rail, the flipping control component drives the first blocking plate, the second blocking plate and the third blocking plate to rotate to a horizontal position, and then the second driving rod drives the third blocking plate to move outward, so that the second guide rod moves outward along the second restraint sleeve, and the first guide rod moves outward along the first restraint sleeve, so that the third blocking plate moves outward stably, and the second blocking plate also follows the outward movement, thereby realizing the deployment of the side blocking assembly.

[0063] In this embodiment, the flip control component includes a linkage plate 77 and a flip gear 7311. The linkage plate 77 is in the shape of a letter "7".

[0064] In the above scheme: when the first blocking plate moves outward, the matching plate will first move along the part of the outward guide rail without teeth, and the first blocking plate will not rotate. When the matching plate moves to the interference bar, the interference bar will interfere with the outward movement of the linkage plate, and the engaging tooth seat will disengage from the flip gear. Subsequently, the flip gear will contact the teeth groove, and as the first blocking plate moves outward, the teeth groove drives the flip gear to rotate, so that the first blocking plate rotates outward to a horizontal position.

[0065] In this embodiment, the ultraviolet irradiation assembly 8 includes a first back plate 81, a second back plate 82, a third back plate 83, a fourth back plate 84 and an ultraviolet lamp 85.

[0067] In this embodiment, an inner frame 15 is symmetrically provided on the inner wall of the main chassis 1 . The inner frame 15 is arranged close to the inspection window, and the retracted ultraviolet irradiation component 8 is stoppered and inserted into the inner frame 15 .

[0068] In the above scheme: the inner frame can block the received ultraviolet irradiation component, and the inner frame contacts each back plate to ensure the shape stability of the ultraviolet irradiation component when it is folded, and can also support the ultraviolet irradiation component to prevent the ultraviolet irradiation component from falling.

[0069] In this embodiment, the inner guide plate 6 includes a vertical guide plate 61, a guide fold plate 62 and a horizontal guide plate 63. The guide fold plate 62 is relatively arranged on the inner side of the inner baffle frame 15. The top of the guide fold plate 62 is connected to the horizontal horizontal guide plate 63, and the bottom end is connected to the vertically arranged vertical guide plate 61. The top of the horizontal guide plate 63 is connected to the exhaust duct 12. A serpentine airflow channel is formed between the guide fold plate 62 and the retracted ultraviolet irradiation assembly 8. The bottom of the vertical guide plate 61 is connected to the air inlet duct 11.

[0070] In the above scheme: the gas entering the air inlet pipe can first enter the area between the vertical guide plate and the first back plate, and then be fully guided and sterilized along the guide fold plate. Finally, the sterilized gas is discharged to the exhaust pipe through the horizontal guide plate.

[0071] In this embodiment, the suspension assembly 4 includes an upper hanging tube 41, a lower movable rod 42 and a hook 43. The upper hanging tube 41 is arranged on the side wall of the main chassis 1. The internal damping sliding of the upper hanging tube 41 is embedded with the lower movable rod 42.

[0072] The lower sealing assembly 3 includes a fixed plate 31, a tooth plate 32, a support plate 33 and a sealing plate 34. The top of the fixed plate 31 is fixedly connected to the main chassis 1, the bottom end of the fixed plate 31 is rotatably connected to the support plate 33 and a driven gear 331 is installed at the rotating connection. The outer side of the driven gear 331 is meshed and connected to the vertically arranged tooth plate 32. The bottom end of the tooth plate 32 is fixedly connected to the bottom end of the lower movable rod 42. The outer end top surface of the support plate 33 is provided with a sealing plate 34, and the sealing plate 34 cooperates to seal the air inlet duct.

[0073] In the above scheme: when the movable rod is pulled down, the tooth plate will be driven to follow and fall down, and the tooth plate drives the driven gear to rotate, thereby driving the supporting plate and the sealing plate to rotate upward, so that the sealing plate seals the air inlet duct.

[0074] In order to achieve sterilization around the bed, the following solution is given:
