[0029] Example 1

[0030] Example 1 is basically as shown in the appendix. Figures 1-3 As shown, Figure 1 The air filtration system for the hospital isolation ward shown includes a sterilization chamber 1, with an air inlet pipe 2 connected to the upper right side of the sterilization chamber 1 and an air outlet pipe 3 connected to the upper left side. The air filtration system for the hospital isolation ward also includes a stirring assembly, a driving component, and an exhaust assembly. The stirring assembly is located between the sterilization chamber 1 and the air inlet pipe 2, the driving component provides power to the stirring assembly, and the exhaust assembly is located between the sterilization chamber 1 and the air outlet pipe 3.

[0031] The mixing assembly includes a chute 4, a mounting shell 9, several sliders 5, and a vent pipe 10, such as... Figure 2 As shown, the chute 4 is formed on the upper inner wall of the sterilization chamber 1. The chute 4 is radially arranged in a circular shape outside the air inlet pipe 2, and the longitudinal section of the chute 4 is a C-shaped chute 4. In this embodiment, there are 3 sliders 5, which are slidably installed inside the chute 4. Each slider 5 has a connecting rod 6 rotatably installed at its lower end. Figure 3 Each connecting rod 6 shown has a fixed ring 7 fixedly installed at its lower end. A driven gear 8 is fixedly installed on the outer wall of the fixed ring 7. The mounting shell 9 is fixedly installed inside the fixed ring 7, and as shown... Figure 2The upper end of the mounting shell 9 extends into the air inlet pipe 2, and the outer wall of the end of the mounting shell 9 that extends into the air inlet pipe 2 is sealed and rotatably connected to the inner wall of the air inlet pipe 2, thereby preventing air from directly entering the sterilization chamber 1. Several vent pipes 10 are radially fixedly installed at the lower end of the mounting shell 9, and each vent pipe 10 is connected to the mounting shell 9. Of course, the several vent pipes 10 and the mounting shell 9 can be produced using an integral molding technology. Several vent holes 11 are opened on the outer wall of each vent pipe 10, and each vent hole 11 is located below the horizontal level of the disinfectant solution.

[0032] The exhaust assembly includes a drive gear 12, a push rod 13, a cover plate 15, and a boss 16, such as Figure 2 As shown, the transmission gear 12 is rotatably mounted on the upper inner wall of the sterilization chamber 1, and the transmission gear 12 meshes with the driven gear 8. The push rod 13 is fixedly mounted on the upper end of the transmission gear 12. The inner wall of the air inlet pipe 2 is fixedly mounted with a limiting ring 14. The cover plate 15 is hinged to the upper end of the limiting ring 14, and the diameter of the cover plate 15 is larger than the inner diameter of the limiting ring 14, so that the cover plate 15 can completely cover the limiting ring 14 to prevent the leakage of volatile disinfectant. The boss 16 is fixedly mounted on the lower end of the cover plate 15, and the lower end of the boss 16 extends into the sterilization chamber 1. The upper end of the push rod 13 can contact the lower end of the boss 16. The opposite ends of the push rod 13 and the boss 16 are both set as arc surfaces. The exhaust assembly can control the exhaust of air in the sterilization chamber 1, prevent the filtered air and volatile disinfectant from being directly discharged from the sterilization chamber 1, increase the residence time of air and volatile disinfectant in the sterilization chamber 1, and increase the effect of air sterilization.

[0033] The driving components include a motor 17 and a drive gear 18, such as Figure 3 As shown, the motor 17 is fixedly installed on the inner wall of the sterilization chamber 1, and the driving gear 18 is fixedly installed on the output end of the motor 17, and the driving gear 18 meshes with the driven gear 8.

[0034] The outer wall of the motor 17 is fitted with an anti-corrosion shell to protect the motor 17. The transmission gear 12, driven gear 8 and driving gear 18 are all made of corrosion-resistant materials.

[0035] The specific implementation process is as follows:

[0036] When air filtration and purification are required, an appropriate amount of water can be poured into sterilization chamber 1, and then disinfectant or chlorine-containing effervescent disinfectant tablets can be added to prepare a disinfectant solution. Then, by starting motor 17, the mounting shell 9 is rotated, which in turn drives the vent pipe 10 to agitate within sterilization chamber 1, ensuring the disinfectant solution components are evenly mixed. At this time, air from the isolation ward enters the mounting shell 9 through the air inlet pipe 2, and then enters the disinfectant solution through the vent hole 11 in the vent pipe 10. The air and disinfectant solution are thoroughly mixed, achieving the effect of air filtration and purification. As the mounting shell 9 continues to rotate, the driven gear ring also drives the corresponding... When the meshing transmission gear 12 rotates, and the push rod 13 moves to below the boss 16 as the transmission gear 12 rotates, the push rod 13 contacts the boss 16, and the boss 16 moves upward along the arc surface set between the two, thereby lifting the cover plate 15 and forming a gap between the cover plate 15 and the limiting ring 14. Only then can air be discharged from the sterilization chamber 1, which greatly improves the air filtration and purification effect. Furthermore, before the push rod 13 and the boss 16 contact each other, the sterilization chamber 1 is in a closed state, and the disinfectant volatilized inside fully contacts the air, further improving the air purification effect and reducing the risk of cross-infection in the hospital.

[0037] Example 2

[0038] Example 2 is largely the same in principle as Example 1, the difference being that the driving component includes a rotating rod 19 and a rotating blade 20, as shown below. Figure 4 As shown, the upper end of the rotating rod 19 is rotatably mounted on the inner wall of the air intake pipe 2, the lower end of the rotating rod 19 is fixedly mounted on the inner wall of the lower end of the mounting shell 9, and the rotating blade 20 is fixedly mounted on the outer wall of the rotating rod 19 and located at the air inlet of the air intake pipe 2.

[0039] The interaction between the air intake pipe 2 and the rotating blade 20 drives the rotating rod 19 to rotate, which can save energy. At the same time, the greater the air intake of the air intake pipe 2, the faster the rotation speed of the stirring component. This ensures that the air and disinfectant are in full contact, while also increasing the air exhaust speed in the sterilization chamber 1 and preventing a large amount of air from accumulating in the sterilization chamber 1.

[0040] Example 3

[0041] The difference in Example 3 is that it also includes a submersible tube 21, such as Figure 5 As shown, the submersible tube 21 is located at the lower end of the air inlet tube 2, and several baffles 22 are provided at the upper end of the submersible tube 21. The baffles 22 can be suspended in the disinfectant water. The baffles 22 are semi-circular and concave in the middle.

[0042] When air enters the submersible pipe 21 through the air inlet pipe 2, the bubbles formed in the disinfectant are of inconsistent sizes. Smaller bubbles rise faster in the disinfectant and have a shorter residence time, resulting in reduced filtration and purification. To increase the residence time of air in the disinfectant, a baffle 22 restricts small bubbles from directly escaping the submersible pipe 21. When the small bubbles below the baffle 22 converge into larger bubbles, the buoyancy of the larger bubbles exceeds the weight of the baffle 22, thus lifting the baffle 22 and allowing the larger bubbles to exit the submersible pipe 21. This increases the residence time of small bubbles in the disinfectant and improves the filtration and purification effect on the air.
