[0003] Because the high-frequency and high-voltage electric field of ozone generator can easily cause overheating in some areas, it can cause micro-cracks or thermal recession of ceramic substrate. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the utility model provides a kind of ceramic substrate structure of ozone generator, which can solve the problem of micro-cracks or thermal recession of ceramic substrate caused by high-frequency and high-voltage electric field of ozone generator.

[0005] The utility model is realized as follows:

[0006] The utility model provides a kind of ceramic substrate structure of ozone generator, wherein, including ceramic substrate, high-voltage electrode, ground electrode, dielectric layer and sealing adhesive layer, the ceramic substrate is cuboid, and the upper surface and the lower surface are provided with recess, for accommodating the high-voltage electrode and the ground electrode;The high-voltage electrode is comb-shaped, connected with high-voltage power supply through wire, and the toothed part is matched with the recess of the upper surface of the ceramic substrate;The ground electrode is flat, matched with the recess of the lower surface of the ceramic substrate, and connected with ground wire through wire;The dielectric layer covers between the high-voltage electrode and the ceramic substrate;The high-voltage electrode, the ground electrode, the dielectric layer and the ceramic substrate are all provided with the sealing adhesive layer, to form sealed overall structure, to prevent ozone leakage and arc discharge.

[0007] On the basis of the above technical solutions, the ceramic substrate structure of the ozone generator can be further improved as follows:

[0008] The upper surface and the lower surface of the ceramic substrate are provided with a plurality of uniformly distributed through holes for cooling the ozone generator.

[0009] Further, the tip of the tooth-shaped part of the high-voltage electrode is a rounded structure for reducing the electric field strength, preventing corona discharge, and improving the yield and purity of ozone.

[0010] Further, the dielectric layer is formed by stacking multiple thin films of different materials, each thin film having different dielectric constant and voltage resistance, to improve the insulation performance and voltage resistance of the dielectric layer and prevent the dielectric layer from being punctured.

[0011] Further, the sealing glue layer is made of silicone rubber or epoxy resin.

[0012] Further, a heat-conducting layer is provided between the ground electrode and the ceramic substrate to improve the heat dissipation efficiency of the ground electrode.

[0013] Further, the ceramic substrate is made of alumina ceramic material.

[0014] Further, the high-voltage electrode and the ground electrode are both made of metal material.

[0015] Further, the edge of the ceramic substrate is provided with a sealing ring to further improve the sealing performance and prevent ozone leakage.

[0016] Further, the dielectric layer is made of glass or ceramic material.

[0017] Compared with the prior art, the ceramic substrate structure of the ozone generator provided by the present application has the following advantages:

[0018] The ceramic substrate serves as a support and isolates the electrodes in the ozone generator. Its cuboid structure helps maintain the position and stability of the electrodes. The ceramic material has excellent electrical insulation, high temperature resistance, and mechanical strength, so it can effectively withstand high-voltage electric fields and provide good thermal stability. The recesses on the upper and lower surfaces of the ceramic substrate allow the high-voltage electrode and the ground electrode to be accurately embedded therein, ensuring stable installation of the electrodes. The upper and lower surfaces of the ceramic substrate are provided with a plurality of uniformly distributed through holes for cooling. Since the ozone generator generates a lot of heat when working, these through holes help reduce the temperature by air circulation and prevent overheating.

[0019] The high-voltage electrode is responsible for generating a high-voltage electric field, exciting oxygen molecules in the air, and generating ozone. Its comb-shaped shape and toothed part match the design of the groove on the upper surface of the ceramic substrate, allowing the high-voltage electrode to be firmly fixed on the substrate and providing efficient electric field distribution. The toothed part of the high-voltage electrode is designed with a rounded tip to reduce the electric field strength at the tip and avoid the occurrence of corona discharge. Corona discharge can cause damage to the electrode surface and reduce ozone production, while the rounded corner can effectively reduce local high electric field strength, thereby improving ozone production and purity.

[0020] The main function of the ground electrode is to form an electric field with the high-voltage electrode and ensure the complete flow of current. Its flat design matches the groove on the lower surface of the ceramic substrate, allowing it to be stably fixed on the substrate and connected to the ground wire through a wire. A heat-conducting layer is provided between the ground electrode and the ceramic substrate to improve heat dissipation efficiency and ensure that the ground electrode can effectively dissipate heat to prevent performance degradation due to overheating.

[0021] The dielectric layer is located between the high-voltage electrode and the ceramic substrate and is mainly used to increase insulation to prevent direct contact between the high-voltage electrode and the ground electrode, thereby avoiding arc discharge. The material selection and structural design of the dielectric layer are crucial to the performance of the generator. The dielectric layer is made up of multiple layers of thin films of different materials, each layer having different dielectric constants and voltage resistance, making it have high insulation performance and voltage resistance. This multi-layer structure can effectively prevent the dielectric layer from breaking down under high voltage, thereby ensuring the long-term stable operation of the device. The dielectric layer can be made of glass or ceramic materials, which have excellent electrical insulation properties and high-temperature resistance, making them suitable for high-voltage ozone generation environments.

[0022] The sealing glue layer is used to package the various components (such as the high-voltage electrode, the ground electrode, the dielectric layer, and the ceramic substrate) into a tight whole, preventing ozone gas leakage and avoiding arc discharge. The sealing glue has good high-temperature resistance, voltage resistance, and corrosion resistance, effectively maintaining the sealing of the ozone generator. Common sealing glue materials include silicone rubber and epoxy resin, both of which have good adhesion, temperature resistance, and electrical insulation, ensuring long-term stable operation.

[0023] The edge of the ceramic substrate is provided with a sealing ring to further improve the sealing performance and prevent ozone gas leakage.

[0024] The high-voltage electrode and the ground electrode are usually made of metal materials (such as stainless steel or aluminum alloy), which have good electrical conductivity and corrosion resistance and can withstand long-term high-voltage discharge. BRIEF DESCRIPTION OF DRAWINGS
