Description

Technical Field

[0001] This utility model relates to the field of air sterilizer technology, and in particular to a sealed connection structure for a plasma air sterilizer. Background Technology

[0002] During plasma air disinfection, in order to ensure that the air in the disinfection area can fully interact with the plasma, it is necessary to prevent untreated air from leaking in or treated clean air from leaking out. The sealed connection structure can ensure that the air flows in the disinfection unit according to the designed path, allowing the air to stay in the disinfection unit for a sufficient time and fully contact the plasma, thereby improving the disinfection effect. In places with high requirements for air disinfection, the sealed connection structure can effectively prevent bacteria and viruses in the outside air from entering the disinfection area, while preventing the leakage of clean air after disinfection, and ensuring the hygiene quality of indoor air.

[0003] A sealed structure helps maintain stable internal air pressure in the sterilizer. During operation, it is essential to ensure normal airflow and pressure balance to guarantee plasma generation and effectiveness. Gas leakage can lead to unstable internal air pressure, affecting airflow path and residence time within the sterilizer, thus reducing sterilization efficiency. Existing technologies often use rubber sealing rings with good elasticity and corrosion resistance. These materials maintain stable performance under different working environments and adapt to chemical and temperature changes within the sterilizer. However, these sealing devices are difficult to disassemble after installation. Over time, the sealing rings age, harden, and become brittle, reducing elasticity and preventing effective filling of gaps in the connection points, resulting in decreased sealing performance and gas leakage. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sealing connection structure for a plasma air sterilizer, aiming to improve the problems in the prior art where such sealing equipment is difficult to disassemble after installation, and the sealing ring ages after prolonged use, leading to a decrease in the elasticity of the sealing material and an inability to effectively fill the gaps in the connection parts, thus resulting in a decline in sealing performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sealed connection structure for a plasma air sterilizer, comprising a connecting column, a fixing plate 1 fixedly connected to the top of the outer wall of the connecting column, a tapered tube 1 connected to the top of the inner wall of the connecting column, a fixing plate 2 fixedly connected to the middle of the outer wall of the tapered tube 1, a plurality of bolts 1 threadedly connected to the bottom of the fixing plate 1, a tapered tube 2 connected to the bottom of the connecting column, a nut threadedly connected to the top of the outer wall of the bolts 1, a support ring fixedly connected to the upper middle part of the inner wall of the connecting column, a sealing ring provided at the top of the support ring, and a sterilization mechanism provided at the bottom of the connecting column, the sterilization mechanism being used for filtering, sterilizing, and discharging the gas.

[0006] As a further description of the above technical solution:

[0007] The disinfection mechanism includes an air intake box, the bottom of which is connected to the top of the first conical tube. The top of the air intake box is connected to an air inlet. The bottom of the second conical tube is equipped with a disinfection box. The right side of the outer wall of the disinfection box is connected to an air outlet. A baffle is fixedly connected to the middle of the inner wall of the connecting column, and a filter plate is fixedly connected to the lower middle part of the inner wall of the connecting column.

[0008] As a further description of the above technical solution:

[0009] The bottom of the disinfection box is fixedly connected to a base plate, and a gasket is provided on the outer wall of the bolt.

[0010] As a further description of the above technical solution:

[0011] The top front and rear sides of the disinfection box are fixedly connected with sponge blocks, and the top left and right sides of the disinfection box are fixedly connected with rubber blocks.

[0012] As a further description of the above technical solution:

[0013] A controller is fixedly connected to the front of the disinfection box, and a sealing ring is fixedly connected to the left side of the outer wall of the air outlet.

[0014] As a further description of the above technical solution:

[0015] A display screen is fixedly connected to the front left end of the controller, and a knob is provided on the front right end of the controller.

[0016] As a further description of the above technical solution:

[0017] The top of the disinfection box is fixedly connected to multiple support columns, and the top of each support column is fixedly connected to a limit ring.

[0018] As a further description of the above technical solution:

[0019] A fixing ring is fixedly connected to the middle of the outer wall of the tapered tube II, and multiple bolts are threadedly connected to the top of the fixing ring.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, a tapered tube is inserted into the inner wall of the connecting column, so that its outer wall contacts and squeezes the sealing ring. The sealing ring opens to block the gap. Then, a bolt is turned through the fixing plate and the fixing plate, and then the nut is turned to enhance the sealing effect. This achieves full sealing of the equipment interface and facilitates disassembly and replacement, thereby improving the maintenance efficiency of the staff.

[0022] 2. In this utility model, the controller starts the air intake box to draw in external gas. The gas enters the equipment through the air inlet.

[0032] Specifically, the connecting column 1 is fixedly connected to the fixing plate 3, which not only enhances the stability of the structure but also provides a solid foundation for the installation of subsequent components. The connecting column 1 is connected to the tapered tube 4, which helps guide the gas flow and improve the gas treatment efficiency. The fixing plate 5 ensures the stability of the connection. The fixing plate 3 is threadedly connected to multiple bolts 6, which facilitates assembly and ensures the reliability of the connection. The connecting column 1 is connected to the tapered tube 7, taking into account the overall fluid dynamics characteristics and ensuring smooth gas passage.

[0033] Please see the appendix Figure 2 Appendix Figure 4 and attached Figure 5 The disinfection mechanism 2 includes an air intake box 202, the bottom of which is connected to the top of the conical tube 4. An air inlet 201 is connected to the top of the air intake box 202. A disinfection box 205 is provided at the bottom of the conical tube 7. An air outlet 206 is connected to the right side of the outer wall of the disinfection box 205. A baffle 203 is fixedly connected to the middle of the inner wall of the connecting column 1. A filter plate 204 is fixedly connected to the lower middle part of the inner wall of the connecting column 1. A plurality of support columns 15 are fixedly connected to the top of the disinfection box 205. A limit ring 16 is fixedly connected to the top of the support column 15.

[0034] Specifically, the intake box 202 is connected to the conical tube 4 to ensure smooth air intake. The air inlet 201 not only serves as a channel for air exchange between the system and the outside environment, but also takes into account airflow efficiency and noise control. The disinfection box 205 is responsible for thoroughly disinfecting the intake air. The air outlet 206 allows the disinfected air to be smoothly discharged, while ensuring the durability and reliability of the disinfection effect. The baffle 203 plays a key guiding role in the system, ensuring that the air is evenly distributed into the intake box 202 after passing through the conical tube 4. The filter plate 204 can effectively remove small particles and impurities in the air, ensuring air cleanliness. The support column 15 provides structural stability. The limiting ring 16 is to ensure that each component can be kept in the correct position during equipment operation, avoiding equipment failure caused by vibration or movement, thereby ensuring the stable operation and long-term reliability of the entire system.

[0035] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3The bottom of the disinfection box 205 is fixedly connected to a base plate 18, and a gasket 22 is provided on the outer wall of the bolt 6. Sponge blocks 14 are fixedly connected to the front and rear sides of the top of the disinfection box 205, and rubber blocks 13 are fixedly connected to the left and right sides of the top of the disinfection box 205.

[0036] Specifically, the bottom of the disinfection box 205 is fixedly connected to the base plate 18, ensuring the stability and durability of the equipment.

The display screen 21 can clearly display the operating status and parameters of the equipment. The knob 20 has a comfortable feel, and users can easily adjust the working mode and parameters of the disinfection box 205 through the knob 20. The operation is simple and intuitive.

[0039] Working principle: Insert the tapered tube 4 into the inner wall of the connecting column 1, so that the outer wall of the tapered tube 4 contacts the inner wall of the sealing ring 10. Since the outer wall of the tapered tube 4 is inclined, moving it downward will squeeze the sealing ring 10, causing the sealing ring 10 to open outward, thereby blocking the gap between the tapered tube 4 and the connecting column 1. At this time, tighten the bolt 6, which will pass through the fixing plate 3 and the fixing plate 5. Then tighten the nut 8, so that the tapered tube 4 and the sealing ring 10 can be fully squeezed, thereby improving the sealing effect and achieving full sealing at the equipment interface. It is also convenient for disassembly and replacement, thereby improving the maintenance efficiency of the staff.

[0040] The air intake box 202 is activated by the controller 19. The air intake box 202 draws in outside air, which enters the equipment through the air inlet 201. The baffle 203 blocks larger impurities in the air, preventing blockage of the bottom filter plate 204. The filter plate 204 filters smaller particles in the air, facilitating the subsequent disinfection process. After being filtered, the air enters the disinfection box 205 for disinfection, and is finally discharged through the air outlet 206. This achieves multiple filtration and disinfection of the air, improving the cleanliness of the air and making the discharged air fresher.

[0041] 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.
