The modular structure is adopted, which can be used as long as it is assembled, and the middle module can be stacked and combined to realize ozone generators of different specifications and outputs. It has a simple structure, is easy to combine, and is easy to produce and maintain. The basic modules of the present invention are three types: a high-voltage end module, a middle module, and a gas-water nozzle end module. Each module has the same structure, and the interface docking positions between the modules correspond, so that the gas-guiding and water-cooling pipelines can be interconnected without pipelines. The mutually superimposed and combined middle modules and the supporting parts are exactly the same, so the superposition becomes very simple. Since the low-voltage electrode surface spacing between the modules is fixed and parallel to each other, as long as the high-voltage electrode plate and the dielectric sheet are placed in the set installation position and the high-voltage electrode sheet is threadedly connected, no debugging is required, and it can work normally after installation, achieving the purpose of being able to maintain the equipment without professional engineers, and solving the problem of inconvenient after-sales maintenance.

The high-voltage corona electric field for generating ozone is completed in the concave position of the dielectric sheet, and the concave position of the dielectric sheet is connected to the central hole of the module, so that the ozone is gathered in the central hole of the module and output from the air outlet nozzle of the air-water nozzle end module at the front end.

[0017] 4. The high-voltage electrode sheet and low-voltage electrode surface that generate the high-voltage corona electric field are flat. The front and back sides of a high-voltage electrode sheet correspond to two low-voltage electrode surfaces, so that a corona electric field is generated on both sides of a high-voltage electrode sheet, which greatly increases the area of ​​the electric field and doubles the amount of ozone generated by a single side.

[0018] 5. The electrical connection is simple. No matter how many modules are combined, there is only one terminal for inputting the high-voltage current inside the main body. Each module can be connected by connecting a connecting conductive rod. Due to the design of the connecting conductive rod sheath, the electrical connection and the ozone transport channel are the same center hole of the module. The center is the high-voltage circuit channel, and the rest of the center hole is the ozone channel, so one hole can be used for multiple purposes. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] It should be noted that, in the description, in order to make the language concise, the water outlet holes and the water outlet holes 1, 2 and 3 in the present invention are in a genus-species relationship in language logic, that is, the water outlet holes include: water outlet holes 1, 2 and 3, and similarly, the dielectric sheet recess includes: dielectric sheet recess 1 and dielectric sheet recess 2; the low-voltage electrode plane includes: low-voltage electrode plane 1 and low-voltage electrode plane 2, low-voltage electrode plane 3 and low-voltage electrode plane 4; the center hole includes: center hole 1, center hole 2 and center hole 3, the dielectric sheet includes dielectric sheet 1 and dielectric sheet 2; the high-voltage electrode sheet includes: high-voltage electrode sheet 1 and high-voltage electrode sheet 2. The annular groove includes annular groove 1, annular groove 2, annular groove 3 and annular groove 4.

[0044] The following is further described with reference to the accompanying drawings: refer to Figures 1 to 4 , among which Figure 1 This is a three-dimensional diagram of one embodiment of the present invention, including: a high-voltage end module 1, a middle module 2, and an air-water nozzle module 3, with a high-voltage electrode assembly 6 inside, a water inlet nozzle 311 and a water outlet nozzle 321 for water supply circulation, an air inlet nozzle 351 for oxygen or air input, and an ozone outlet nozzle 341 outside, and a set of fixing screws 4 between the molds through the screw holes on each mold to fix the mold. In order to make the schematic diagram more concise and clear in the description, the decomposition Figure 3The internal high-voltage electrode assembly 6 is omitted. This embodiment includes: three different modules: high-voltage end module 1, middle module 2, gas and water nozzle module 3 and a set of high-voltage electrode assemblies 6. The central hole 18 at the back of the high-voltage end module is provided with a connection end for high-voltage current input, that is, a high-voltage conductive screw 62 in the high-voltage electrode assembly. The high-voltage current input wire is electrically connected to the rear end of the high-voltage conductive screw. The connection is connected by a terminal and then fixed with a fixing nut 61. The fixing nut not only fixes the terminal, but also fixes the high-voltage sheath seat 63 and other connected high-voltage electrode assemblies, so that the entire high-voltage electrode assembly will not shake; the high-voltage current is input to the high-voltage electrode sheet 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 can form a loop as long as it is connected to any point of one of the modules, so that the device can work normally. During operation, a high-voltage corona electric field is generated between the high-voltage electrode sheet and the low-voltage electrode surface. Oxygen enters from the air inlet nozzle 351, and then passes through the gap between the high-voltage electrode sheet and the low-voltage electrode surface, namely the corona electric field space, so that the oxygen molecules passing through the electric field undergo an electrochemical reaction, thereby generating ozone. The ozone is output from the ozone outlet nozzle 341 through the central hole 2 of the middle module and the central hole 3 34 of the air-water nozzle module.

[0045] During operation, the ozone generator will continuously generate heat. In order to make the operation stable, each module must be cooled. The present invention adopts water cooling. Traditional water cooling sets many water cooling pipes, resulting in a complex structure. The present invention adopts a water-free setting between modules. The cooling through the internal water channel makes the structure simple, the volume is greatly reduced, and the performance is stable. As long as the module and the matching parts are connected, it can work normally, reducing the difficulty of production installation and maintenance. That is, the front air-water nozzle end module panel is provided with a water inlet nozzle 311, a water outlet nozzle 321, an air inlet nozzle 351 and an ozone outlet nozzle 341 for water cooling. The longitudinal and transverse water channels of each module have the same structure, and the interface is set on the connection surface of the module. The modules are sealed and connected to each other, and a sealing ring is set at the connection. The end of the processed hole on the side wall of the water channel is provided with a plug 5. The middle module can be stacked and combined as needed. No matter how many combinations there are, there are no other pipes entering except the pipes for supplying water to the equipment and the circulating water outlet pipe. Each module is provided with a set of screw holes corresponding to the position, and connected with the matching module fixing screw 4, which is firmly fixed and convenient for installation and disassembly maintenance. The combination of three modules of the present invention is the most basic combination, such as Figure 1 and Figure 6 As shown, on this basis, as long as the middle module and the matching components are superimposed in front of the middle module, an ozone generator that produces different amounts of ozone can be formed. Figure 7 The figure shows that there are two middle modules stacked in the middle, forming an ozone generator of the second embodiment composed of four modules. By analogy, several or even dozens of modules can be further stacked and expanded on this basis to meet different needs.

The conductive screw seat is provided in the middle hole 1 of the high-voltage end module, and its front end is in contact with the high-voltage electrode sheet 1 661 in the dielectric sheet recess 16, that is, flush. The front part of the conductive screw passes through the middle hole 6611 of the electrode sheet of the high-voltage electrode sheet 1, and the connecting conductive rod screw hole 682 is connected with the conductive screw thread and tightens the high-voltage electrode sheet 1 by tightening the thread; the connecting conductive rod is provided with a screw at the front end and a screw hole at the rear end, so that multiple parts can be connected to each other. By adding a connecting conductive rod, the high-voltage end can be extended inside the module. When multiple middle modules need to be combined, each time a middle module is added, a connecting conductive rod is added to conduct the added high-voltage electrode sheet. In this embodiment, the connecting conductive rod screw 681 passes through the connecting conductive rod 68 in the center hole 2 of the middle module and is connected to the dielectric sheet middle hole 6511 of the high voltage electrode sheet 2 662 provided in the dielectric sheet recess 24 and is fixed with the fixing nut 2 69. When the middle modules are stacked, the fixing nut 2 69 always fixes the front side of the frontmost high voltage electrode sheet.

[0051] In some specific embodiments, in order to facilitate the selection of materials, the dielectric sheet of the embodiment of the present invention 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 air conduction, so that the oxygen used to generate ozone can flow smoothly in the annular groove of the template. The high-voltage electrode sheet is a circular stainless steel mesh sheet, which is woven with wires, so that criss-cross gaps are formed between the large surfaces on both sides and the dielectric sheet, and the gaps are spread throughout the entire stainless steel mesh sheet. The outer diameter of the high-voltage electrode sheet is smaller than the outer diameter of the dielectric sheet. Due to the setting of the annular groove of the module, oxygen passes evenly from all sides of the annular groove through the gap between the circular stainless steel mesh and the ceramic sheet, that is, ozone is continuously generated through the high-voltage corona electric field.

[0052] In some specific embodiments, in order to facilitate the positioning of the conductive screw seat 64 and the high-voltage conductive screw 62, an annular step 110 protruding toward the axis is provided in the central hole 18 of the high-voltage end module 1. The annular step corresponds to the position of the sealing ring step on the conductive screw seat and is sealed and connected. This arrangement not only facilitates the sealing of the sealing ring, but also prevents the high-voltage sheath seat from moving forward and backward under the action of the fixing nut 61 on the high-voltage sheath seat 63 and the high-voltage conductive screw. In this way, the connection between the high-voltage electrode sheet connected to the high-voltage conductive screw and the continuous conductive rod 68 is more stable.

[0053] Reference Fig. 20 , is another embodiment of the dielectric sheet, the dielectric sheet is a T-shaped dielectric sheet three 653, the dielectric sheet three is an enamel sheet, there is a circular sheet 6531 on it, the upper surface is a plane, the function of the circular sheet is the same as that of the dielectric sheet, the vertical is a cylindrical shape 6532, the circular sheet and the cylindrical shape are stamped into one piece, the surface is processed with enamel, the circular sheet is arranged in the concave position of the dielectric sheet, the high-voltage electrode sheet is arranged between the planes of the upper parts of the two T-shaped dielectric sheets three and clamps the high-voltage electrode sheet, the vertical cylinder is arranged on the inner side of the inner wall of the center hole of the two adjacent modules, the advantage of the T-shaped dielectric sheet is that the cylinder plays a role in radial positioning, so that the dielectric sheet will not slide in the radial direction, and the axial direction is positioned by two adjacent low-voltage electrode surfaces, so that the dielectric sheet is more stable in the equipment, even if there is a large vibration, it will not be displaced. The circular sheet of this embodiment clamps the high-voltage electrode sheet 66 during use. The T-shaped enamel sheet is more durable because the base material is metal, and the enamel plays an insulating isolation role.

[0054] The dielectric sheet recess of the present invention refers to the position where the dielectric sheet and the high-voltage electrode sheet are placed, that is, the position where a high-voltage electrode sheet is sandwiched between two dielectric sheets. In this embodiment, the dielectric sheet recess is a circular groove recessed into the module, and the depth is equal to the thickness of the two dielectric sheets and the high-voltage electrode sheet superimposed. The dielectric sheet recess setting includes two types: one is that the dielectric sheet recess is set on one of the modules, and its depth is the thickness of the two dielectric sheets and the high-voltage electrode sheet superimposed; the other is that the dielectric sheet recess is set on the connecting surface of two adjacent modules, and its depth is half each, that is, two dielectric sheets and a high-voltage electrode sheet are connected. The dielectric sheet recess of the present invention is not limited to the embodiments of the present invention, and the dielectric sheet recess can be on any module. The bottom surface of the dielectric recess of this embodiment is the low-voltage electrode plane on one side, and the low-voltage electrode plane on the other side is the connection surface of another module. The corresponding two low-voltage electrode planes are parallel to each other, which is formed by mechanical precision machining. As long as they are installed normally, they must be parallel. Since the thickness of the dielectric sheets is the same, the high-voltage electrode sheet sandwiched between the two dielectric sheets is also parallel to the two low-voltage electrode planes and will not be displaced, so the working performance is very stable.

[0055] Different combinations of modules constitute ozone generators of different specifications. The basic combination of the present invention is a combination of three modules, such as Figure 1 and Figure 2 As shown; but it does not exclude the high-pressure end module 1 and the air-water nozzle module 3, the combination can also work normally, but this combination produces a small amount of ozone. In order to meet different needs, different numbers of middle modules 2 must be combined and superimposed between the high-pressure end module 1 and the air-water nozzle module 3, such as Fig. 9 As shown, there are two middle modules in the middle. For each additional middle module, two dielectric sheets, a high-voltage electrode sheet, and a connecting conductive rod 68 and a connecting conductive rod sheath for electrical connection with the high-voltage electrode sheet are added in front of the middle module 2. A high-voltage electrode sheet is sandwiched between the two dielectric sheets. By analogy, there can be as few as a few or as many as dozens for connection to meet the needs of different specifications. The combination is convenient and fast. As long as it is installed in the normal orientation, it can maintain stable operation even without debugging, which brings great convenience to after-sales service. As long as there are accessories, ordinary engineers can assemble, repair, and even increase gas production through assembly.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
