[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 and Figure 2 An infectious disease clinical air purification device includes a disinfection box 1 installed on top of an isolation bed inside an infectious disease ward. A partition plate 2 is fixedly connected inside the disinfection box 1 to separate the disinfection box 1, forming an air disinfection zone 101 and a spare zone 102 inside the disinfection box 1. Both the air disinfection zone 101 and the spare zone 102 contain a disinfectant solution for air disinfection. The disinfectant solution can be a disinfectant or a targeted solution can be prepared according to the different infectious pathogens.

[0025] like Figure 1 and Figure 2 A horizontal pipe 3 is fixedly connected to one side of the inner wall of the disinfection box 1. The horizontal pipe 3 is a corrosion-resistant metal pipe that can be used for a long time inside the disinfection box 1. An adjustable piston 4 that can move horizontally is installed inside the horizontal pipe 3. The adjustable piston 4 can seal the inside of the horizontal pipe 3. An air input pipe 5 is fixedly connected to the top of the horizontal pipe 3. A spare pipe 6 is fixedly connected to one end of the horizontal pipe 3. An air disinfection pipe 7 is fixedly connected to the bottom of the horizontal pipe 3. The bottom of the air disinfection pipe 7 extends to the bottom of the inner wall of the air disinfection area 101. The spare pipe 6 extends into the interior of the spare area 102. Both the air disinfection pipe 7 and the spare pipe 6 extend into the interior of the disinfection liquid inside the disinfection box 1. The height of the disinfection liquid does not exceed the height of the partition plate 2.

[0026] like Figure 1The disinfection box 1 is equipped with an exhaust fan 8 on one side. The exhaust fan 8 is installed on the top of the isolation bed inside the infectious disease ward. It is connected to an external power supply and has a corresponding control switch. The exhaust fan 8 has an air outlet and one end of the air inlet pipe 5 fixedly installed. The exhaust fan 8 has an air inlet pipe 9 fixedly installed at the air inlet. One end of the air inlet pipe 9 extends into the interior of the isolation bed inside the infectious disease ward, which can extract the air inside the isolation bed. The isolation bed is equipped with corresponding air intake equipment to ensure the air pressure balance inside and outside the isolation bed.

[0027] like Figure 2 and Figure 3 The top of the transverse pipe 3 is provided with a trapezoidal connecting part 301. The trapezoidal connecting part 301 can ensure that the air input pipe 5 will not be blocked when the adjusting piston 4 moves. The air in the air input pipe 5 can always enter the interior of the transverse pipe 3. The trapezoidal connecting part 301 is connected to the air input pipe 5 and is used to connect the air input pipe 5 and the transverse pipe 3.

[0028] like Figure 2 and Figure 3 One end of the transverse pipe 3 is threadedly connected to an adjusting screw 10. One end of the adjusting screw 10 is rotatably connected to an adjusting piston 4, which is used to drive the adjusting piston 4 to move horizontally. The other end extends to the outside of the disinfection box 1, making it easy to manually rotate the adjusting screw 10. A sealing piston 11 is rotatably connected to the outer surface of the adjusting screw 10. There are annular protrusions on the adjusting screw 10 and at both ends of the sealing piston 11. When the adjusting screw 10 moves, the annular protrusions can squeeze the sealing piston 11, causing the sealing piston 11 to move together. The sealing piston 11 can prevent the air inside the transverse pipe 3 from leaking outward. A limiting ring 12 is fixedly connected inside the transverse pipe 3. The limiting ring 12 can block the movement of the sealing piston 11 and restrict the movement of the sealing piston 11 and the adjusting piston 4.

[0029] like Figure 1 The disinfection box 1 has a transparent window 13 on its outside, through which the liquid content inside the disinfection box 1 can be observed. The top of the disinfection box 1 has an inlet pipe, and a sealed top cover 14 is threaded onto the inlet pipe. An outlet pipe 15 is fixedly connected to the outside of the disinfection box 1. There are two transparent windows 13, two sealed top covers 14, and two outlet pipes 15, which correspond to the air disinfection area 101 and the spare area 102, respectively.

[0030] like Figure 1 and Figure 4The top of the disinfection box 1 is fixedly connected to an exhaust pipe 16, and one end of the exhaust pipe 16 is fixedly connected to a connecting chamber 17. The bottom of the connecting chamber 17 has a pipe opening that can discharge air. A diatomaceous earth particle filter layer 18 and an activated carbon filter layer 19 are fixedly installed on the connecting chamber 17. The air after passing through the disinfection box 1 will pass through the diatomaceous earth particle filter layer 18 and the activated carbon filter layer 19 again, thereby improving the air purification capacity.

[0031] The working principle of the infectious disease clinical air purification device provided by this utility model is as follows:

[0032] In the clinical diagnosis and treatment of infectious diseases, when patients are isolated in isolation beds in infectious disease wards, exhaust fan 8 can be started. Exhaust fan 8 draws in air from inside the isolation bed through air intake pipe 9 and inputs it into the horizontal pipe 3 through air input pipe 5, and then into the disinfectant solution inside the air disinfection area 101 through air disinfection pipe 7 for disinfection and purification.

[0033] When it is necessary to replace the chemical solution inside the air disinfection zone 101, the adjusting screw 10 can be turned counterclockwise to move the adjusting piston 4 above the air disinfection pipe 7, thus sealing the air disinfection pipe 7. At this time, air enters the chemical solution inside the spare zone 102 through the spare pipe 6 for disinfection and purification, and then the chemical solution inside the air disinfection zone 101 is replaced.

[0034] Compared with related technologies, the clinical air purification device for infectious diseases provided by this utility model has the following beneficial effects:

[0035] This invention creates an air disinfection zone 101 and a backup zone 102 inside the disinfection box 1. During normal use, air enters the air disinfection zone 101 through the air disinfection pipe 7 for disinfection and purification. When changing the disinfectant solution in the disinfection box 1, the adjusting screw 10 can be rotated to drive the adjusting piston 4 to close the air disinfection pipe 7, allowing air to enter the backup zone 102 through the backup pipe 6 for disinfection and purification. This enables the disinfection box 1 to continuously disinfect and purify the air in the isolation beds inside the infectious disease ward.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
