[0033] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0034] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0035] likeFigures 1-2 As shown in the embodiment of this application, an air disinfection and sterilization device for a central air conditioning system based on molecular knockdown technology is provided, such as... Figure 9 As shown, the air disinfection and sterilization device 100 is installed in the return air duct of the central air conditioning ventilation system.

[0036] Specifically, such as Figures 1-2 As shown, the air disinfection and sterilization device 100 includes two oppositely arranged insulating mounting parts 1, multiple negative electrode plates 2 connected between the two insulating mounting parts 1, and multiple positive electrode shafts 3 connected between the two insulating mounting parts 1. The multiple negative electrode plates 2 are arranged vertically at intervals, with equal spacing between adjacent negative electrode plates 2. Each positive electrode shaft 3 is located between adjacent negative electrode plates 2, with equal spacing between the positive electrode shaft 3 and adjacent negative electrode plates 2. When a high-voltage pulse current is applied to the positive electrode shaft 3, a uniform electric field is formed between the positive electrode shaft 3 and adjacent negative electrode plates 2. Because the positive electrode shaft 3 and adjacent negative electrode plates 2 are equidistantly arranged and uniformly discharged, a uniform electric field is formed, and there is no local high-voltage arcing phenomenon, thus effectively avoiding ozone generation and release.

[0037] Ozone has a strong oxidizing effect on equipment, which can cause the equipment to be damaged very quickly. In addition, ozone release will have a strong oxidizing effect on people and objects in the vicinity, which is harmful to human health and can damage indoor electronic equipment and other objects. Therefore, the air disinfection and sterilization device 100 in this embodiment does not have the problem of generating ozone.

[0038] During operation, a uniform electric field ionizes the air to form high-energy particles, making ionization more efficient and safer. These high-energy particles can break the molecular bonds of pollutants and destroy the DNA genetic information of harmful microorganisms, thus killing them. They can also decompose harmful gases and purify smoke and dust.

[0039] In this embodiment, the positive electrode shaft 3 includes a shaft and discharge structures uniformly arranged along the shaft axis. The discharge structures are integrally formed with the shaft and are positioned directly opposite the negative electrode plate 2. After energization, the discharge structures discharge, forming a uniform electric field between themselves and the negative electrode plate 2. This uniform electric field is a high-voltage pulse electric field.

[0040] Specifically, such as Figure 3 As shown, the discharge structure can be thread 4, meaning the positive shaft 3 can be a screw, discharging through the arc-shaped edge of thread 4. Alternatively, as... Figure 4 As shown, the discharge structure can also be a discharge ring 5, which is concentrically arranged with the shaft. The outer wall surface of the discharge ring 5 has an annular discharge blade. Multiple discharge rings 5 ​​are closely arranged along the shaft and discharge through the annular discharge blade on the outer wall surface of the discharge ring 5.

[0041] It should be noted that, Figure 3 and Figure 4The specific discharge structure shown in the figure is only a part of all discharge structures capable of forming a uniform electric field between the negative electrode plate 2. It can be understood that the discharge structure can also have other structural forms, which are not described here.

[0042] In the embodiment, the vertical distance between the discharge structure tip and the negative electrode plate 2 is 5-20 mm, and the preferred vertical distance is 13 mm. The material of the positive electrode shaft 3 and the material of the negative electrode plate 2 can be stainless steel or galvanized steel, thereby playing a rust-proof and anti-oxidation role.

[0043] Compared with the existing air purifier in which a tungsten wire structure is used as a positive electrode, the tungsten wire is easy to break and damage, while the positive electrode shaft 3 is basically not damaged instead of the tungsten wire. The traditional tungsten wire structure is easy to break and damage, and must be regularly maintained and replaced with a tungsten wire. The positive electrode shaft 3 and the negative electrode plate 2 are almost not damaged throughout the use cycle, so there is no need for maintenance, no consumables are generated, and the maintenance cost is greatly reduced.

[0044] In order to reduce the wind resistance coefficient of the negative electrode plate 2, make the gas flow more smooth, and ensure the airflow velocity in the return air pipeline, in the embodiment, as shown in Figure 1 , Figure 2 and Figure 7 , the negative electrode plate 2 is designed as a V-shaped plate structure. Specifically, when installed, the central axis surface of the negative electrode plate 2 is horizontally arranged, and the airflow flows from the tip side of the negative electrode plate 2 to the opening end. The opening angle of the negative electrode plate 2 is 5°-30°, and the preferred opening angle is 10°.

[0045] In addition, in the working process, the uniform electric field between the positive electrode shaft 3 and the negative electrode plate 2 ionizes the air to generate ion wind, and the electronic charge moves to the negative electrode plate 2 to drive the air flow, so that the airflow flows from the wide opening between the adjacent two negative electrode plates 2 to the narrow opening, that is, the airflow automatically flows towards the inside of the return air pipeline.

[0046] As shown in Figure 5 , one side surface of the insulating mounting piece 1 is provided with a connecting groove 7 for connecting the negative electrode plate 2, and the end of the negative electrode plate 2 is inserted into the connecting groove 7. The ends of all negative electrode plates 2 connected to the same insulating mounting piece 1 are fixedly connected to the insulating mounting piece 1 through the conductive negative electrode connecting piece 8. The negative electrode connecting piece 8 is fixedly connected to the insulating mounting piece 1 through a bolt. The insulating mounting piece 1 can be fixedly installed on the inner wall of the return air pipeline through a bolt during installation.

[0047] The side surface of the insulating mounting 1 is provided with a second connecting pipe 13 for connecting the positive pole shaft 3, and the end of the positive pole shaft 3 is inserted into the second connecting pipe 13. The ends of all the positive pole shafts 3 connected with the same insulating mounting 1 are connected through the conductive fixing plate 14 after being outwardly led out from the second connecting pipe 13, and the end surface of the positive pole shaft 3 is fixedly connected with the fixing plate 14 through a bolt. In actual installation, one of the fixing plates 14 at the two ends of the positive pole shaft 3 is connected with the positive pole wire of the power supply.

[0048] The second connecting pipe 13 is provided with an extension pipe 12 outside the concentric and spaced structure, and the extension pipe 12 and the second connecting pipe 13 form a multi-ring isolation structure, which greatly increases the creepage safety distance between the positive pole shaft 3 and the negative pole plate 2, thereby avoiding the occurrence of arc and fire phenomenon, and making the air disinfection and sterilization device provided in the embodiment have a high safety factor.

[0049] As shown in Figure 1 , the air disinfection and sterilization device 100 further comprises an insulating support 9 connected in the middle of the positive pole shaft 3 and the negative pole plate 2, for providing support to the positive pole shaft 3 and the negative pole plate 2, reducing the deformation of the positive pole shaft 3 and the negative pole plate 2 due to deflection when the length dimension exceeds a set value, avoiding the spacing error between the positive pole shaft 3 and the negative pole plate 2 from exceeding a set value, and enabling the electric field between the positive pole shaft 3 and the negative pole plate 2 to remain uniform and stable. It should be noted that the insulating support 9 can be provided with multiple, for example, two, three or four, etc., according to the length dimension of the positive pole shaft 3 and the negative pole plate 2, and the spacing between the adjacent two insulating supports 9 can be reasonably adjusted according to the length of the positive pole shaft 3 and the negative pole plate 2. In actual installation, the insulating support 9 is fixedly connected at both ends to the inner wall of the air return pipe.

[0050] Specifically, as shown in Figure 6 , the insulating support 9 is provided with a negative pole jack 10 corresponding to the negative pole plate 2, and the negative pole jack 10 is a trapezoidal hole matched with the negative pole plate 2, the negative pole plate 2 is inserted into the negative pole jack 10, and the negative pole jack 10 provides support to the negative pole plate 2. As shown in Figure 7 , the ends of all the negative pole plates 2 connected with the same insulating support 9 are fixedly connected with the insulating support 9 through a conductive negative pole connecting piece 8. The negative pole connecting piece 8 is fixedly connected with the insulating support 9 through a bolt.

[0051] The insulating support 9 is further provided with a first connecting pipe 11 corresponding to the positive pole shaft 3, and the first connecting pipe 11 extends to the outside of the insulating support 9, and the positive pole shaft 3 is inserted into the first connecting pipe 11 in a matched manner, and the first connecting pipe 11 provides support to the positive pole shaft 3.

[0052] The first connecting pipe 11 is externally concentric with and spaced apart from the extension pipe 12. Similarly, the extension pipe 12 and the first connecting pipe 11 form a multi-ring isolation structure, greatly increasing the creepage safety distance between the positive shaft 3 and the negative plate 2, thereby avoiding the occurrence of arc drawing and fire bridging, and making the air disinfection and sterilization device provided in the embodiment have a high safety factor.

[0053] As shown in Figure 8 The negative connecting piece 8 is in the form of a strip, and has a clamping portion 15 adapted to the open end of the negative plate 2. The clamping portion 15 is a protrusion in the form of a trapezoid punched on the negative connecting piece 8. When the negative plate 2 is fixed, the clamping portion 15 extends into the opening of the negative plate 2, and the two side walls of the clamping portion 15 are tightly fitted with the inner wall of the negative plate 2, thereby clamping the negative plate 2 in the connecting groove 7 on the insulating mounting piece 1 and the negative insertion hole 10 on the insulating support piece 9.

[0054] In actual installation, a plurality of negative connecting pieces 8 are connected to each negative plate 2, and only one of the negative connecting pieces 8 needs to be connected to the negative wire.

[0055] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
