DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figure 1 and Figure 2The ozone treatment device shown in the figure includes a shell 1, a processing unit 2 arranged in the shell 1, an air inlet 3 and an air outlet 4 are set on the shell 1, the air inlet 3 is connected to the exhaust port of the corona machine, and the air outlet 4 is designed as a narrow structure, such as a trumpet shape. The narrow design of the air outlet 4 can reduce the discharge flow rate of ozone, increase the time the ozone is in the shell 1, ensure sufficient reaction and decomposition, and evenly apply sealant to all gaps on the surface of the shell 1 to prevent air leakage; the processing unit 2 includes a fixing frame 21, a plurality of parallel electrode assemblies 22 arranged on the fixing frame 21, and a terminal 5 for supplying power to the electrode assembly 22. The terminal 5 includes a high-voltage terminal and a grounding terminal. A ventilation gap 24 is formed between adjacent electrode assemblies 22. Ozone can pass through the formed ventilation gap 24 and can contact the surface of the electrode assembly 22 at the same time, thereby improving the thermal decomposition effect. The electrode assembly 22 includes an electrode 223 and a fixing assembly for fixing the electrode 223. The electrode 223 is connected to the high-voltage terminal of the terminal 5, and the fixing assembly is connected to the grounding terminal of the terminal 5. The terminal 5 is connected to high voltage electricity, and discharge occurs between the electrode 223 and the fixing assembly, causing the surface temperature of the fixing assembly to rise. Ozone enters the outer shell 1 and is decomposed by the high-temperature air and converted into oxygen for emission.

[0024] In order to improve the fixing and heat dissipation effects, the fixing assembly includes an upper splint 221, a lower splint 222 and a connector. The electrode 223 is arranged between the upper splint 221 and the lower splint 222. Several electrodes 223 are arranged in parallel and do not intersect. There is an electrode gap 2210 between the electrodes 223 and the electrodes 223. The electrode gap 2210 between two adjacent electrodes 223 is the same. The upper splint 221 and the lower splint 222 are fixed by a connector. The connector can be in various forms, such as a snap-on structure, a screw structure, etc. In this solution, a screw structure is used. The upper splint 221 and the lower splint 222 are connected by a light hole 228 and a threaded hole 229. The arrangement of the light hole 228 and the threaded hole 229 can be set in two forms:

[0025] In the first form, a plurality of light holes 228 are provided on the upper clamping plate 221, and a plurality of threaded holes 229 are provided at corresponding positions of the lower clamping plate 222, that is, one light hole 228 corresponds to one threaded hole 229, and a screw passes through the light hole 228 and is screwed into the threaded hole 229 to achieve clamping; and the light hole 229 can also be provided on the lower clamping plate 222, and the corresponding threaded hole 229 is provided on the upper clamping plate 221; this connection method requires distinguishing between the upper clamping plate 221 and the lower clamping plate 222 during the manufacturing process, and when performing maintenance and replacement, the corresponding upper clamping plate 221 or lower clamping plate 222 is required, which is very inconvenient during replacement.

[0026] The second form is to set a light hole 228 on one side of the upper splint 221 and a threaded hole 229 on the other side of the upper splint 221, or the light hole 228 and the threaded hole 229 are staggered, so that the upper splint 221 and the lower splint 222 can be used interchangeably, and there is no need to distinguish between the upper splint 221 and the lower splint 222. When one of them is damaged, it can be easily replaced. For example, if the upper splint 221 is damaged, it can be replaced with a new lower splint 222.

[0027] The upper clamping plate 221 includes an upper flat plate and several upper protruding ends 224 extending from the upper flat plate to one side, and the upper protruding ends 224 are inserted into the electrode gap 2210; the lower clamping plate 222 includes a lower flat plate and several lower protruding ends 225 extending from the lower flat plate to one side, and the lower protruding ends 225 are inserted into the electrode gap 2210. Multiple protruding ends can be inserted into the electrode gap 2210, and the upper clamping plate 221, the lower clamping plate 222 and the protruding ends form a radiator structure, which can quickly transfer the heat generated by discharge.

[0028] The position where the upper clamping plate 221 and the lower clamping plate 222 clamp the electrode 223 can have two structures:

[0029] In the first structure, the position where the upper clamping plate 221 and the lower clamping plate 222 clamp the electrode 223 is flat, and discharge is directly contacted with one surface of the electrode 223. However, the close surface-to-surface contact is not conducive to discharge and heat dissipation.

[0030] The second structure, such as Figure 3 As shown, the upper clamping plate 221 is provided with an upper boss 226 toward the electrode 223 at a position where the electrode 223 is clamped, and the lower clamping plate 222 is provided with a lower boss 227 toward the electrode 223 at a position where the electrode 223 is clamped. The electrode 223 is located between the upper boss 226 and the lower boss 227. At the same time, the contact area between the upper boss 226 and the lower boss 227 and the electrode 223 is smaller than the area of a single side of the electrode 223. At the same time, the upper boss 226 can be set to multiple, and the lower boss 227 can also be set to multiple. The multiple upper bosses 226 and the multiple lower bosses 227 cooperate to clamp the electrode 223. There are gaps between the multiple upper bosses 226, and there are also gaps between the multiple lower bosses 227, which facilitates heat dissipation.

[0031] Both of the above structures can drive the internal air movement through the fan, thereby improving the heat transfer effect and making the heat in the heating space diffuse quickly and evenly.

[0032] The distance between the adjacent electrode assemblies 22 is controlled at 20-30 mm. At the same time, the distance between adjacent electrodes 223 in each electrode assembly 22 is also controlled at 20-30 mm. This can prevent the occurrence of the phenomenon of burning the electrodes 223 due to excessive local temperature caused by too small a space, while also ensuring a good heating effect.

[0033] Based on the above structure, the outer shell of the electrode 223 is a long ceramic tube body, which is hollow inside. Its cross section can be designed into various forms according to needs, such as circular, triangular, square, rectangular or other special-shaped structures. In this solution, it is designed to be square for easy clamping and discharge. Figure 4 The electrode 223 shown includes a hollow insulating shell 2231, a wire 2232 located inside the hollow insulating shell 2231, a metal powder filler 2233 filled between the wire 2232 and the hollow insulating shell 2231, a connecting wire 2235 extending outward from the wire 2232, and insulating fillers 2234 located at both ends of the electrode 223. The wire 2232 is located at the center of the hollow insulating shell 2231, and the metal powder filler 2233 surrounding it is used for electrical conduction. The powder filler can better fill the hollow area without leaving an unfilled area. domain, discharge evenly during use, avoiding the risk of concentrated discharge breakdown caused by uneven discharge; the connecting wire 2235 introduces the external high voltage into the wire 2232, and the wire 2232 transfers it to the metal powder filler 2233, so that the inside of the electrode 223 is charged as a whole, and then the electrode 223 discharges between the upper clamping plate 221 and the lower clamping plate 222 to generate heat; the insulating fillers 2234 arranged on both sides can ensure that the internal metal powder filler 2233 will not leak, and can also ensure that the arc will not be drawn out from the two ends of the electrode 223, thereby ensuring safety.

[0034] At the same time, in order to facilitate the fixation and lead-out of the connecting wire 2235, a lead-in hole is opened on the surface of the hollow insulating shell 2232, and the connecting wire 2235 passes through the lead-in hole and is connected to the wire 2232. An insulating fixing part 2236 is provided on the lead-in hole to fix the connecting wire 2235, and a connector is provided at the end of the connecting wire 2235, which can be conveniently connected to the wiring terminal.

[0035] Furthermore, in order to prevent the insulating filler 2234 at both ends of the electrode 223 from leaking, plugs 2237 are provided at both ends of the electrode 223 , and the plugs 2237 are also made of insulating material.

[0036] Since the fixing assembly and the electrode 223 need to be charged, the fixing frame 21 does not need to be charged to ensure safety. Therefore, an insulating member 23 is set between the fixing assembly and the fixing frame 21 to separate them. At the same time, the bolts for fixing the connection are also made of non-conductive material.

[0037] In summary, through the design of the upper clamping plate 221, the lower clamping plate 222 and the protruding end, the electrode 223 can be conveniently clamped while ensuring uniform heat distribution. By controlling the size distance, the required heating effect can be achieved while ensuring safety, and ozone can be quickly decomposed to improve efficiency.

[0038] It should be emphasized that the above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
