[0048] It should be noted that, in the description, for the sake of simple language, the water outlet hole and the water outlet hole one and the water outlet hole two, the water outlet hole three in the utility model are in the logical relationship of species, that is, the water outlet hole includes: the water outlet hole one, the water outlet hole two and the water outlet hole three, and the dielectric sheet recess includes: the dielectric sheet recess one and the dielectric sheet recess two; The low-voltage electrode plane includes: low-voltage electrode plane one and low-voltage electrode plane two, low-voltage electrode plane three and low-voltage electrode plane four; The center hole includes: the center hole one, the center hole two and the center hole three, the dielectric sheet includes the dielectric sheet one, the dielectric sheet two; The high-voltage electrode sheet includes: the high-voltage electrode sheet one and the high-voltage electrode sheet two. The annular groove includes annular groove one, annular groove two, annular groove three and annular groove four.

[0049] The following will be further described with reference to the drawings:

[0050] Reference Figures 1 to 4 , wherein Figure 1 is the perspective view of one embodiment of the utility model, including: high-voltage end module 1, middle module 2, gas and water nozzle module 3, internally provided with high-voltage electrode assembly 6, externally provided with water inlet nozzle 311 and water outlet nozzle 321 for water circulation and gas inlet nozzle 351 and ozone gas outlet nozzle 341 for oxygen or air input, a group of fixed screw rods 4 pass through the screw through holes on each mold to fix the molds. In the description, in order to make the schematic diagram more simple and clear, the exploded view of the utility model is shown in the figure, and the high-voltage electrode assembly 6 is fixed on the high-voltage end module 1 through a group of fixed screw rods 4, and the high-voltage electrode assembly 6 is fixed on the high-voltage end module 1 through a group of fixed screw rods 4. Figure 3The internal high-voltage electrode assembly 6 is omitted. This embodiment includes three different modules: a high-voltage end module 1, a middle module 2, and an air / water nozzle module 3, and a set of high-voltage electrode assembly 6. A high-voltage current input connection terminal, namely the high-voltage conductive screw 62 in the high-voltage electrode assembly, is located in the central hole 18 at the rear of the high-voltage end module. The high-voltage current input wire is electrically connected to the rear end of the high-voltage conductive screw. The connection uses a terminal block and is then fixed with a fixing nut 61. The fixing nut not only fixes the terminal block but also the high-voltage sheath 63 and other connected high-voltage electrode assemblies, preventing the entire high-voltage electrode assembly from shaking. The high-voltage current is input to the high-voltage electrode plates through the high-voltage conductive screw and the connecting conductive rod. The low-voltage end is the low-voltage electrode plane of each module, so the low-voltage end lead only needs to be connected to any point in one of the modules to form a circuit, enabling the equipment to operate normally. During operation, a high-voltage corona electric field is generated between the high-voltage electrode plate and the low-voltage electrode surface. Oxygen enters from the air inlet 351 and then passes through the gap between the high-voltage electrode plate and the low-voltage electrode surface, i.e., the corona electric field space, causing the oxygen molecules passing through the electric field to undergo an electrochemical reaction, thereby producing ozone. The ozone is produced from the ozone outlet 341 through the central hole 2 of the middle module and the central hole 34 of the air-water nozzle module.

[0051] During operation, the ozone generator continuously generates heat. To ensure stable operation, each module needs to be cooled. This invention employs water cooling. Traditional water cooling systems involve numerous water-cooling pipes, resulting in a complex structure. This invention uses a waterless design between modules, cooling through internal water channels, simplifying the structure, significantly reducing size, and ensuring stable performance. It can operate normally simply by connecting the modules and matching components, reducing the difficulty of production, installation, and maintenance. Specifically, the front air / water nozzle module panel is equipped with a water inlet 311, a water outlet 321, an air inlet 351, and an ozone outlet 341 for water cooling. The longitudinal and transverse water channels of each module have identical structures, with interfaces located on the module's connection surface. The modules are sealed and interconnected, with sealing rings at the connections. Plugs 5 are installed at the machined holes on the side walls of the water channels. The middle modules can be stacked and combined as needed. Regardless of the number of combinations, no other pipes enter the internal structure except for the water supply pipe and the circulating water outlet pipe. Each module has a set of screw holes corresponding to its position, which are connected by matching module fixing screws 4 for secure fixing and easy installation, disassembly, and maintenance. The combination of the three modules in this utility model is the most basic combination, such as... Figure 1 and Figure 6 As shown, by simply stacking the middle module and supporting components in front of it, ozone generators producing different amounts of ozone can be formed. For example... Figure 7 The diagram shows two central modules stacked together, forming the ozone generator of the second embodiment, which consists of four modules.

[0057] In some specific embodiments, in order to facilitate the selection of materials, the dielectric sheet of the embodiment of the utility model is a circular ceramic sheet with a thickness of 0.5-1.5 mm; in order to facilitate the entry of oxygen, the outer diameter of the circular sheet is smaller than the outer diameter of the outer side of the annular groove for guiding the gas, so that the oxygen for generating ozone can flow freely in the annular groove of the template; the high-voltage electrode sheet is a circular stainless steel mesh sheet, and the mesh sheet is woven from wire, so that the vertical and horizontal staggered gaps are formed between the dielectric sheet on both sides; the outer diameter of the high-voltage electrode sheet is smaller than the outer diameter of the dielectric sheet; due to the arrangement of the annular groove of the module, the oxygen uniformly passes through the gaps between the circular stainless steel mesh and the ceramic sheet from the four sides of the annular groove, that is, through the high-voltage corona electric field to continuously generate ozone.

[0058] In some specific embodiments, in order to facilitate the positioning of the electrically conductive screw seat 64 and the high-voltage electrically conductive screw 62, an annular step 110 protruding towards the shaft center is arranged in the central hole 18 of the high-voltage end module 1, and the annular step is in position corresponding to the sealing ring step on the electrically conductive screw seat and is sealingly connected, which not only facilitates the sealing of the sealing ring, but also makes the high-voltage sheath seat not move forward and backward under the action of the fixing nut 61 on the high-voltage electrically conductive screw, so that the connection of the high-voltage electrically conductive screw and the high-voltage electrode sheet connected to the electrically conductive rod 68 is more stable.

[0059] Referring to Figure 20 For another embodiment of the dielectric sheet, the dielectric sheet is a T-shaped dielectric sheet three 653, which is a porcelain sheet, and a circular sheet 6531 is arranged on the porcelain sheet, and the upper surface is a plane. The circular sheet has the same function as the dielectric sheet, and the vertical surface is a cylindrical surface 6532. The circular sheet and the cylindrical surface are integrally formed by stamping, and the surface is processed by porcelain. The circular sheet is arranged in the dielectric sheet recess. The high-voltage electrode sheet is arranged between the two T-shaped dielectric sheet upper planes and clamped. The vertical cylindrical surface is arranged in the inner side wall of the central hole of the two adjacent modules. The advantage of the T-shaped dielectric sheet is that the cylindrical surface plays a role in radial positioning, so that the dielectric sheet cannot slide in the radial direction. The axial direction is positioned by the two adjacent low-voltage electrode surfaces. Therefore, the dielectric sheet is more stable in the equipment, and even if there is a large vibration, the dielectric sheet will not be displaced. In use, the circular sheet of this embodiment clamps the high-voltage electrode sheet 66. The T-shaped porcelain sheet is more durable because the base material is metal. The porcelain plays a role in insulation and isolation.

[0060] The dielectric sheet recess of the utility model refers to the position of placing the dielectric sheet and the high-voltage electrode sheet, that is, the position of clamping a high-voltage electrode sheet between two dielectric sheets. In this embodiment, the dielectric recess is a circular recessed module slot, and the depth is equal to the thickness of two dielectric sheets and a high-voltage electrode sheet. The dielectric sheet recess includes two types: one is that the dielectric sheet recess is arranged on one of the modules, and the depth is equal to the thickness of two dielectric sheets and a high-voltage electrode sheet. The other is that the dielectric sheet recess is arranged on the connecting surface of the two adjacent modules, and the depth is half, that is, half of the thickness of two dielectric sheets and a high-voltage electrode sheet. The dielectric sheet recess of the utility model is not limited to the embodiments of the utility model, and the dielectric sheet recess can be arranged on any one of the modules. The bottom surface of the dielectric recess in this embodiment is the low-voltage electrode plane of one side, and the low-voltage electrode plane of the other side is the connecting surface of the other module. The corresponding two low-voltage electrode planes are parallel to each other. This is formed by mechanical finishing. As long as it is normally installed, it must be parallel. Since the dielectric sheets have the same thickness, the high-voltage electrode sheet clamped between the two dielectric sheets is parallel to the two low-voltage electrode planes and will not be displaced, so the working performance is very stable.

[0061] Different combinations of the modules constitute different specifications of the ozone generator, the basic combination of the present application is the combination of three modules, as shown in Figure 1 and Figure 2 ; but it does not exclude that the high-voltage end module 1 and the gas-water nozzle module 3 can also work normally in combination, but such combination produces small amount of ozone, in order to meet different needs, different numbers of middle modules 2 should be combined and stacked between the high-voltage end module 1 and the gas-water nozzle module 3, as shown in Figure 9 , two middle modules are arranged in the middle, and two dielectric sheets, a high-voltage electrode sheet and a continuation conductive rod 68 and a continuation conductive rod sheath for electrically connecting the high-voltage electrode sheet are added in front of the middle module 2 for each increase of one middle module, one high-voltage electrode sheet is clamped between the two dielectric sheets, and so on, a few or dozens of them can be connected to meet the needs of different specifications, the combination is convenient and fast, as long as it is installed in the normal direction, even without debugging, it can also maintain stable work, which brings great convenience to after-sales service. As long as there are accessories, general engineers can assemble, maintain and even improve the gas production capacity through assembly.

[0062] The above only describes the preferred embodiments of the present application, and does not limit the present application, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
