[0075] In one aspect, in combination with Figures 1 to 10 as shown, an ozone generator is provided in an embodiment of the present disclosure. The ozone generator includes an outer casing 1 and a plurality of discharge units 2.

[0076] The outer housing 1 has a rectangular three-dimensional structure, and a receiving cavity is formed in the outer housing 1;

[0077] A plurality of discharge units 2 are arranged in parallel in the receiving cavity; the plurality of discharge units 2 can be arranged horizontally or vertically in the outer housing 1, and can be specifically set according to actual needs.

[0078] Combined Figure 3 As shown, among them, the discharge unit 2 includes a high-voltage electrode plate 21, a dielectric plate member, a cooling plate member, a grounding electrode plate member, and a gasket.

[0079] The high-voltage electrode plate 21 is used to connect to a high-frequency high-voltage power supply externally; Dielectric barrier discharge can work at high voltage and in a wide frequency range. The normal working voltage is 10 - 10000V, and the power supply frequency can range from 50Hz to 1MHz.

[0080] Exemplarily, in this application, the working voltage of the high-voltage electrode plate 21 is 10000V, and the high-frequency power supply frequency is 60KHz.

[0081] During actual use, the discharge unit 2 can work alone in a group, or multiple groups of discharge units 2 can work in combination.

[0082] In some embodiments of this application, the high-voltage electrode plate 21 is made of a metal material that is heat-resistant and corrosion-resistant.

[0083] Exemplarily, the high-voltage electrode plate 21 is made of a high-purity molybdenum plate material.

[0084] The dielectric plate member is an insulating medium, and the dielectric plate member is attached to the surface of the high-voltage electrode plate 21.

[0085] In some embodiments of this application, the dielectric plate member is made of a ceramic material.

[0086] The cooling plate member is arranged on the side of the dielectric plate away from the high-voltage electrode plate 21; the inside of the cooling plate member is used to pass cooling water, and the cooling water is used to absorb heat to cool down. Therefore, the cooling plate member needs to have good thermal conductivity. Exemplarily, the cooling plate member is made of a high-purity stainless steel or aluminum plate material.

[0087] The grounding electrode plate member is attached to the side of the cooling plate member close to the dielectric plate member; in this application, the grounding electrode plate member and the cooling plate member have the functions of a carrier of a low-voltage electrode and a cooling function. With this structure, a uniform discharge gap can be maintained between the high-voltage electrode plate 21 and the grounding electrode plate member; at the same time, the cooling water is completely isolated from the high-voltage electrode plate 21, improving safety and reliability.

[0088] In some embodiments of the present application, the grounding electrode plate is made of tungsten plate material. Tungsten metal has high hardness, high melting point, is not eroded by air at room temperature, and has relatively stable chemical properties.

[0089] A gasket is disposed between the grounding electrode plate and the dielectric plate; the gasket has a spiral structure. Specifically, the gasket is in the form of an Archimedean spiral. A spiral discharge air gap 40 is jointly formed among the gasket, the dielectric plate and the grounding electrode plate, which increases the oxygen ionization path length and is beneficial to improving the ozone concentration; the outer side of the discharge air gap 40 is the oxygen inlet end 401, and the inner side is the ozone outlet end 402;

[0090] Since ozone has strong oxidizing properties, all materials in contact with ozone are selected to have ozone-resistant characteristics.

[0091] In some embodiments of the present application, the gasket is made of glass fiber material.

[0092] Through holes are formed at positions corresponding to the ozone outlet end 402 on the high-voltage electrode plate 21, the dielectric plate, the cooling plate and the grounding electrode plate, and a plurality of through holes are connected in sequence to form an ozone discharge channel 30.

[0093] Specifically, the cooling plate is used to cool down the grounding electrode plate and the dielectric plate.

[0094] Exemplarily, the discharge unit 2 is provided with 1 to 40 groups.

[0095] Specifically, by providing the outer housing 1 and a plurality of discharge units 2, a receiving cavity is formed in the outer housing 1, and a plurality of discharge units 2 are arranged in parallel in the receiving cavity. The discharge unit 2 includes a high-voltage electrode plate 21, a dielectric plate, a cooling plate, a grounding electrode plate and a gasket. The high-voltage electrode plate 21 is used to externally connect a high-frequency high-voltage power supply, and the cooling plate is used to pass cooling water to cool down the grounding electrode plate and the dielectric plate; by providing a gasket between the grounding electrode plate and the dielectric plate, the gasket has a spiral structure, and a dielectric barrier discharge air gap 40 is formed by enclosing the grounding electrode plate, the gasket and the dielectric plate. The discharge air gap 40 is spiral, and the long path of the discharge air gap 40 can increase the oxygen ionization time, which is beneficial to improving the ozone generation efficiency and thus increasing the ozone output;

[0096] In addition, by arranging the discharge unit 2 in the outer housing 1, the structure is compact and the occupied space is small.

[0097] In the embodiments of the present disclosure, the principle of the ozone discharger adopts dielectric barrier discharge. Dielectric barrier discharge, also known as dielectric barrier corona discharge or silent discharge, is a non-equilibrium gas discharge in which an insulating medium is inserted into the discharge space. During the discharge process between two electrodes, if there is only air and no dielectric barrier in the middle, the air will directly electrolyze and conduct to generate an arc, and the electrical energy is converted into light energy and heat energy. If a dielectric is added between the two electrodes, this direct conduction of air will be blocked, and a discharge corona will be generated on the surface of the dielectric. At this time, high-energy ions are in the space on the surface of the dielectric, decomposing oxygen molecules into oxygen atoms, and the oxygen atoms recombine into ozone molecules.

[0098] Dielectric barrier discharge is usually driven by a sinusoidal AC high-voltage power supply. As the supply voltage increases, the state of the reactive gas in the system will undergo three stages of change, that is, it will gradually change from an insulating state to discharge and finally breakdown.

[0099] In some embodiments of the present application, the dielectric plate member includes a first dielectric plate 22 and a second dielectric plate 23, and the first dielectric plate 22 and the second dielectric plate 23 are respectively attached to both sides of the high-voltage electrode plate 21;

[0100] The ground electrode plate member includes a first ground electrode plate 26 and a second ground electrode plate 27. The first ground electrode plate 26 is arranged on the side of the first dielectric plate 22 away from the high-voltage electrode plate 21, and the second ground electrode plate 27 is arranged on the side of the second dielectric plate 23 away from the high-voltage electrode plate 21;

[0101] Combined Figure 5 and Figure 6 As shown, the gasket includes a first gasket 24 and a second gasket 25. The first gasket 24 is arranged between the first ground electrode plate 26 and the first dielectric plate 22, and the second gasket 25 is arranged between the second ground electrode plate 27 and the second dielectric plate 23.

[0102] Specifically, by setting the first dielectric plate 22, the second dielectric plate 23, the first ground electrode plate 26, the second ground electrode plate 27, the first gasket 24 and the second gasket 25, a first ground electrode plate 26, a first gasket 24, a first dielectric plate 22, a high-voltage electrode plate 21, a second dielectric plate 23, a second gasket 25, and a second ground electrode plate 27 are formed, which are symmetrically distributed up and down or left and right with the high-voltage electrode plate 21 as the center, effectively increasing the discharge area and being beneficial to improving the ozone production.

[0103] In some embodiments of the present application, combined Figure 4 and Figure 5 As shown, the cooling plate member includes a first cooling plate 28 and a second cooling plate 29. The first cooling plate 28 is arranged on the side of the first ground electrode plate 26 away from the first gasket 24, and the second cooling plate 29 is arranged on the side of the second ground electrode plate 27 away from the second gasket 25.

[0104] Specifically, by providing a cooling plate member, it is convenient to cool the grounding electrode plate member.

[0105] It should be noted that in actual application, in order to save costs, simplify the structure and reduce costs, when multiple discharge units 2 are stacked together, the first cooling plate 28 and the second cooling plate 29 in contact with each other between two adjacent discharge units 2 can be combined into one, and the two share a cooling plate member.

[0106] Of course, the first cooling plate 28 and the second cooling plate 29 in contact with each other between two adjacent discharge units 2 can also be independently provided without sharing.

[0107] Combined with Figure 2 As shown in the figure, in some embodiments of the present application, the ozone generator further includes a bus bar 11.

[0108] The bus bar 11 is disposed in the outer housing 1 and divides the accommodation cavity into a first chamber 12 and a second chamber 13;

[0109] Wherein, a part of the discharge units 2 are located in the first chamber 12, and another part of the discharge units 2 are located in the second chamber 13.

[0110] Specifically, by providing the first chamber 12 and the second chamber 13, the discharge units 2 in the first chamber 12 and the second chamber 13 can work independently; in actual application, the discharge units 2 in the first chamber 12 and the second chamber 13 can be used simultaneously; the discharge units 2 are located in the first chamber 12 and the second chamber 13, which is beneficial to improving the cleanliness of ozone.

[0111] At the same time, the first chamber 12 and the second chamber 13 can be arranged horizontally or vertically.

The oxygen supply channel 111 communicates with the oxygen main pipe 3, the first chamber 12 and the second chamber 13, and the oxygen main pipe 3 is configured to be externally connected to an oxygen source.

[0114] In this way, it is convenient to introduce oxygen into the first chamber 12 and the second chamber 13 simultaneously through one oxygen main pipe 3, reducing pipeline connections, simplifying the overall structure, and facilitating processing and manufacturing.
