Description

Technical Field

[0001] The utility model relates to the technical field of ozone water generation, in particular to an ozone generator and a water system. Background Art

[0002] Ozone, composed of three oxygen atoms, is a powerful natural oxidant and disinfectant. The ozone layer in the atmosphere absorbs harmful ultraviolet rays from sunlight, protecting life on Earth. High-purity ozone produced by the ozone industry replaces chlorine disinfection and is widely used in tap water treatment, packaged water, pharmaceutical processing water, and food processing water. Ozone has bactericidal, oxidizing, decolorizing, deodorizing, and advanced oxidation properties in water. When ozone decomposes in water, the hydroxyl radicals produced have powerful oxidizing properties, rapidly breaking down iron, manganese, odors, foul smells, bacteria, and viruses in the water. It can also eliminate chlorine and trihalomethanes in tap water.

[0003] Currently, electrolysis is a typical method for producing ozone. When using electrolysis to produce ozone water, it typically involves an ozone generator. The basic structure of this ozone generator consists of an anode, a cathode, and a membrane sandwiched between them, which acts as a proton exchange membrane. When water flows into the ozone generator, electrolysis removes oxygen from the water molecules and combines them into ozone molecules. This method produces high-purity and high-content ozone, suitable for sterilization, detoxification, preservation, deodorization, and bleaching.

[0004] Some ozone generators are also provided in the prior art. However, the existing ozone generators have a large room for improvement and optimization in many aspects (for example, miniaturization, versatility, etc.).

[0005] Therefore, it is necessary to provide an ozone generator to solve at least one of the above problems. Utility Model Content

[0118] The first electrode 21 is provided with through-holes 210 along its thickness. The proton exchange membrane 23 is in a complete sheet shape, without any holes. When the first electrode 21 functions as an anode, the pores 210 can be used to expand the perimeter of the three-phase interface between the first electrode 21, water, and the proton exchange membrane 23, thereby improving the efficiency of the electrolysis reaction. Furthermore, the presence of the pores 210 on the first electrode 21 facilitates the efficient outflow of ozone water generated at the three-phase interface between the first electrode 21, water, and the proton exchange membrane 23 toward the side facing away from the proton exchange membrane 23.

[0119] The shape, structure, size and distribution position of the pores 210 on the first electrode 21 may vary according to the flushing direction of the water flow, the structure of the first electrode 21, the performance requirements of the ozone generator, etc. For example, Figure 10 As shown, the first electrode 21 may be rectangular in structure, having a relative length direction and width direction. The length of the first electrode 21 is greater than the width direction. The pores 210 may be strip-shaped holes extending along the width direction. There are multiple strip-shaped holes, which are arranged at intervals along the length direction. Specifically, the strip-shaped holes may be rectangular holes with equal widths, or waist-shaped holes with unequal widths.

[0120] When water enters the cavity 1 from the inlet 11, it will flow through the first electrode 21. Since the overall direction of the water flow forms a certain angle with the direction in which the pore 210 extends, for example, roughly vertical, the pore 210 can be directly flushed, which is more conducive to carrying away the generated ozone water and then outputting it through the outlet 12.

[0121] The first electrode 21 has a coating on its first inner surface facing the proton exchange membrane 23. Specifically, the coating may be a deposited precious metal oxide layer. The precious metal oxide layer is gradually consumed during use. Theoretically, the surface area of the precious metal oxide layer is proportional to its service life.

[0122] At the same time, for the first electrode 21 provided with the pores 210, the perimeter of the pores 210 helps increase the perimeter of the three-phase interface when the first electrode 21 functions as an anode, thereby improving the efficiency of the electrolysis reaction. In theory, the longer the perimeter of the three-phase interface increased by providing the pores 210, the greater the effect on improving the efficiency of the electrolysis reaction.

[0123] Taking into account the service life of the first electrode 21 and the efficiency of the first electrode 21 as an anode for electrolysis, the effective area of the first electrode 21 excluding the pores 210 may account for 15% to 95% of the total surface area.

[0124] Specifically, the coating has a thickness between 2 μm and 15 μm. In this application, both the first inner surface of the first electrode 21 and the second inner surface of the second electrode 22 are provided with the coating. The thicker the coating, the longer the lifespan of the electrodes. In the embodiments of this application, it has been verified that the coating provided on the first electrode 21 and the second electrode 22 can at least meet the ozone generator's output requirements for ozone water.

[0125] For the aforementioned sheet-like first and second electrodes 21, 22, and sheet-like proton exchange membrane 23, the first inner surface of the first electrode 21 is bonded to one surface of the proton exchange membrane 23, and the second inner surface of the second electrode 22 is bonded to the other surface of the proton exchange membrane 23. This assembly ensures sufficient contact between the first and second electrodes 21, 22, and the proton exchange membrane 23, while also helping to reduce the dimensions of the stack in the thickness direction.

[0126] In the embodiment of the present application, the first electrode 21 is in direct contact with the proton exchange membrane 23. When the first electrode 21 is an anode, ozone is generated at the three-phase interface of water, the proton exchange membrane 23 and the first electrode 21. After direct contact, the electrolysis reaction can be accelerated and ozone can be generated quickly, thereby effectively improving the efficiency of the ozone generator in generating ozone.

[0127] The first inner surface of the first electrode 21 is bonded to one of the surfaces of the proton exchange membrane 23. Such assembly ensures that the first electrode 21 and the proton exchange membrane 23 are in surface contact. When the first electrode 21 and the proton exchange membrane 23 are bonded to form surface contact, a three-phase interface of the coating of the first electrode 21, water, and the proton exchange membrane 23 is formed at the periphery of the first electrode 21, the proton exchange membrane 23, and the water, as well as at the periphery where the pores 210 are formed. Overall, the electrolysis reaction begins at the outermost edge of the bond. As the reaction time increases, the coating gradually dissolves from the edge inward, thereby helping to extend the service life of the first electrode 21.

[0128] In addition, for the first electrode 21 provided with the pores 210, during use, the perimeter of the outer periphery of the entire first electrode 21 coating gradually decreases, while the perimeter at the pores 210 gradually increases. The increase in the perimeter of the pores 210 can compensate for the decrease in the perimeter of the outer periphery of the entire first electrode 21, thereby facilitating ensuring that the first electrode 21 always has a high electrolysis reaction efficiency when used as an anode.

[0129] In addition, the second inner surface of the second electrode 22 is bonded to the other surface of the proton exchange membrane 23. The technical effect that can be produced can refer to the technical effect produced by the first inner surface of the first electrode 21 being bonded to one surface of the proton exchange membrane 23, and this application will not repeat it here.

[0130] The conductive component can be used to electrically connect the electrode assembly 200 to components outside the cavity 1. The conductive component can include a first portion extending into the cavity 1 and a second portion extending out of the cavity 1, wherein the first portion is connected to the electrode assembly 200.

[0131] In which, when the electrode assembly 200 includes a first electrode 21 and a second electrode 22, the conductive component may include: a first conductor 31 and a second conductor 32, the first part of the first conductor 31 is connected to the first electrode 21, the first part of the second conductor 32 is connected to the second electrode 22, and the second part of the first conductor 31 and the second part of the second conductor 32 are both connected to the control board assembly 400.

[0132] In this embodiment, the shape and structure of the first conductor 31 and the second conductor 32 can be the same or similar. In this embodiment, the first conductor 31 is mainly used as an example for explanation, and the second conductor 32 can be analogously referred to the first conductor 31.

[0133] Specifically, the first conductor 31 can be cylindrical in shape, with a portion thereof extending through the housing 100. The conductor includes a first portion located within the cavity 1 and a second portion located outside the cavity 1. For example, the first conductor 31 can be in the form of a bolt, although other specific forms are also possible. For example, the first conductor 31 can include a nut, a polished rod section, and a threaded section, wherein the nut section is located within the cavity 1, the threaded section can be located outside the cavity 1, and the polished rod section can be located partially within and partially outside the cavity 1.

[0134] Please refer to Figure 7 and Figure 8Furthermore, the first portion of the first conductor 31 is connected to the first electrode 21 via a first component 33. The first component 33 includes: a first electrode contact portion 331 in contact with the first outer surface; and a first connection transition portion 332 connecting the first electrode contact portion 331 to the first portion of the first conductor 31. Similarly, the first portion of the second conductor 32 is connected to the second electrode 22 via a second component 34. The second component 34 includes: a second electrode contact portion 341 in contact with the second outer surface; and a second connection transition portion 342 connecting the second electrode contact portion 341 to the first portion of the second conductor 32.

[0135] In this embodiment, a first component 33 may be provided between the first conductor 31 and the first electrode 21 . The first component 33 may specifically include a first electrode contact portion 331 and a first connection transition portion 332 .

[0136] The first electrode contact portion 331 can be integrally formed with the first connection transition portion 332. Of course, the first electrode contact portion 331 and the first connection transition portion 332 can also be connected by other means, such as welding for a fixed connection or threaded connection for a detachable connection. When the first electrode contact portion 331 and the first connection transition portion 332 are integrally formed, this facilitates a miniaturized design, reduces manufacturing costs, and ensures the reliability of the connection position.

[0137] In this embodiment, a second component 34 may be provided between the second conductor 32 and the second electrode 22. The second component 34 may specifically include a second electrode contact portion 341 and a second connection transition portion 342. Similarly, the second electrode contact portion 341 and the second connection transition portion 342 may be integrally formed, which can facilitate a miniaturized design, reduce manufacturing costs, and ensure the reliability of the connection position.

[0138] The first electrode contact portion 331 is a sheet-shaped frame arranged around the edge of the first outer surface. One end of the first connection transition portion 332 is connected to the first electrode contact portion 331 , and the other end is connected to the first part of the first conductor 31 .

[0139] The first electrode contact portion 331 may be configured as a hollow frame structure, the outer contour of which may be adapted to the outer contour of the first electrode 21. For example, when the outer contour of the first electrode 21 is rectangular, the first electrode contact portion 331 may be a rectangular frame. Of course, the configuration of the first electrode 21 and the specific configuration of the first electrode contact portion 331 may also be other shapes, and this application does not specifically limit their configurations. In the embodiments and drawings of this application, the first electrode contact portion 331 is primarily illustrated as a rectangular frame when the outer contour of the first electrode 21 is rectangular.

[0140] The first connection transition portion 332 may be in the form of a conductive sheet, one end of which is connected to the first electrode contact portion 331 , and the other end of which is connected to the first portion of the first conductor 31 .

[0141] Specifically, a first opening is provided at one end of the first connection transition portion 332 connected to the first part of the first conductor 31, and the first part of the first conductor 31 is passed through the first opening, or the first connection transition portion 332 is fixedly connected to the first part of the first conductor 31 or is integrally formed.

[0142] For example, when the first electrical conductor 31 is in the shape of a bolt, the other end of the first connection transition portion 332 may be provided with a first hole that matches the polished rod section of the bolt, and the bolt may be inserted into the first hole, thereby ensuring that the first connection transition portion 332 maintains reliable contact with the first electrical conductor 31. In addition, the first connection transition portion 332 may be fixed to the first portion of the first electrical conductor 31 by other means, such as by welding, or the first connection transition portion 332 may be integrally formed with the first portion of the first electrical conductor 31. Specifically, this application does not impose any sole limitation on this.

[0143] Similarly, the second electrode contact portion 341 is formed as a sheet-shaped frame around the edge of the second outer surface. One end of the second connection transition portion 342 is connected to the second electrode contact portion 341, and the other end is connected to the second portion of the second conductor 32. Specifically, a second hole is provided at the end of the second connection transition portion 342 connected to the first portion of the second conductor 32, and the first portion of the second conductor 32 is inserted into the second hole. Alternatively, the second connection transition portion 342 is fixedly connected to or integrally formed with the first portion of the second conductor 32.

[0144] In one embodiment, a mounting groove 10 for mounting the electrode assembly 200, the first component 33 and the second component 34 is provided in the cavity 1, and in the depth direction along the mounting groove 10, the first electrode contact portion 331, the first electrode 21, the proton exchange membrane 23, the second electrode 22 and the second electrode contact portion 341 are stacked in sequence.

[0145] In this embodiment, the inner surface of the cavity 1 of the housing 100 can be provided with a predetermined shape. For example, a mounting groove 10 of a predetermined depth can be provided within the cavity 1. The first electrode contact portion 331, the first electrode 21, the proton exchange membrane 23, the second electrode 22, and the second electrode contact portion 341 are sequentially stacked and disposed within the mounting groove 10. The mounting groove 10 can be used to circumferentially position the first electrode contact portion 331, the first electrode 21, the proton exchange membrane 23, the second electrode 22, and the second electrode contact portion 341. Among them, the outer contour dimensions of the first electrode contact portion 331, the first electrode 21, the proton exchange membrane 23, the second electrode 22 and the second electrode contact portion 341 can be equal or nearly equal; further, the circumferential inner contour dimension of the mounting groove 10 can also be equal or nearly equal to the first electrode contact portion 331, the first electrode 21, the proton exchange membrane 23, the second electrode 22 and the second electrode contact portion 341. Such a setting can not only use the mounting groove 10 to reliably position the first electrode contact portion 331, the first electrode 21, the proton exchange membrane 23, the second electrode 22 and the second electrode contact portion 341 in the circumferential direction, but also make the size of the cavity 1 as small as possible, thereby facilitating the miniaturization of the ozone generator.

[0146] like Figure 8 As shown, in one embodiment, the ozone generator further includes: a compressible buffer 44, which is arranged between the second electrode contact portion 341 and the second shell 120. When the second shell 120 is sealed with the first shell 110, the buffer 44 is in a compressed state.

[0147] In this embodiment, the buffer member 44 may be a deformable sheet member having a predetermined thickness.

[0148] The buffer 44 can be made of a flexible material. Specifically, it can include insulating rubber or an insulating spring. For example, the buffer 44 can be made of insulating rubber. When the buffer 44 is made of insulating rubber, it can utilize the rubber's deformability to provide the aforementioned cushioning effect. Furthermore, it can serve as an insulating protective element, improving the compactness of the ozone generator and enhancing its safety during use.

[0149] Specifically, the thickness of the middle portion of the buffer 44 can be less than the thickness of the two sides. The thicker sides of the buffer 44 can be in contact with the second electrode contact portion 341 and the second shell 120, and the thinner portion in the middle can face the pore 210 of the second electrode 22. A certain gap is formed between the thinner portion and the second electrode 22, so that the second electrode 22 provided with the pore 210 is not completely blocked by the buffer 44, especially the area provided with the pore 210 is not blocked by the buffer 44. When water enters through the inlet 11, it can flow through the gap into the area of the electrode provided with the pore 210, thereby carrying away the ozone water with a higher concentration in the pore 210 area and outputting it to the user's water terminal.

[0150] like Figure 6 and Figure 7 As shown, further, a plurality of limiting portions 16 are provided in the cavity 1 , and the limiting portions 16 cooperate with the buffer member 44 to limit the buffer member 44 .

[0151] In order to limit the position of the buffer member 44, especially to limit the position of the buffer member 44 in the circumferential direction, a plurality of limiting portions 16 can be provided within the cavity 1. The number and form of the limiting portions 16 can be adapted according to the shape and structure of the buffer member 44. For example, when the buffer member 44 is an overall rectangular sheet structure, the four corners of the buffer member 44 can be provided with limiting holes. Accordingly, the limiting portions 16 can be in the form of a plurality of small protrusions formed on the inner wall of the cavity 1, with the position and size of the small protrusions adapted to the position and size of the limiting holes.

[0152] Of course, the specific setting method of the limit part 16 can also be other methods and is not limited to the above description. Technical personnel in the relevant field may make other changes based on the technical essence of this application. However, as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0153] like Figure 6As shown, in some embodiments, the cavity 1 is provided with a notch 18 on one side of the electrode assembly 200 for leading out the first connection transition portion 332 and the second connection transition portion 342, and the cavity 1 is also provided with a blocking member 15 for isolating the first connection transition portion 332 and the second connection transition portion 342.

[0154] In this embodiment, the cavity 1 is provided with a mounting groove 10 for mounting the electrode assembly 200, the first component 33 and the second component 34. The mounting groove 10 has a predetermined depth to meet the requirements for mounting the electrode assembly 200, the first component 33 and the second component 34.

[0155] A notch 18 may be provided on one side of the mounting groove 10 , and the notch 18 is used to lead out the first connection transition portion 332 of the first component 33 and the second connection transition portion 342 of the second component 34 to correspondingly connect different conductors (the first conductor 31 and the second conductor 32 ).

[0156] In order to prevent the first connection transition portion 332 and the second connection transition portion 342 from contacting each other during use, forming a short circuit, and thus affecting the reliability of the ozone generator, a blocking member 15 can be provided in the cavity 1 to isolate the first connection transition portion 332 and the second connection transition portion 342. Specifically, the blocking member 15 can be a baffle having a certain height provided on the inner wall of the cavity 1. Of course, the specific structure of the blocking member 15 can be adaptively adjusted according to the specific layout position of the first connection transition portion 332 and the second connection transition portion 342, and this application does not make the sole limitation here. The blocking member 15 can be formed in the cavity 1 by integral injection molding, so as to simplify the structure, reduce costs, and ensure the reliability of the cooperation between the blocking member 15 and the cavity 1.

[0157] like Figure 6 As shown, in one embodiment, the first conductor 31 and the second conductor 32 are located on the same side of the electrode assembly 200 .

[0158] In this embodiment, the first conductor 31 and the second conductor 32 can be located on the same side of the electrode assembly 200. Compared with the manner in which the first conductor 31 and the second conductor 32 are located on different sides, the cavity 1 only needs to add a structure for assembling conductive components on one side of the electrode assembly 200, that is, the first conductor 31 and the second conductor 32 located on the same side can efficiently utilize the structure for assembling conductive components on one side of the electrode assembly 200, which is beneficial to reducing the volume of the ozone generator and making it miniaturized.

[0159] Please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 Specifically, in a first direction X along the inlet 11 to the outlet 12, the first electrode 21 or the second electrode 22 has a first size, and in a second direction Y perpendicular to the inlet 11 to the outlet 12, the first electrode 21 or the second electrode 22 has a second size, and the first conductor 31 and the second conductor 32 are arranged at intervals along the first direction X.

[0160] In this embodiment, the first electrode 21 or the second electrode 22 has a first size in a first direction X from the inlet 11 to the outlet 12, i.e., the overall flow direction of the fluid, and has a second size in a second direction Y perpendicular to the first direction X. The first size can be greater than or equal to the second size, or the first size can be smaller than the second size. The first conductors 31 and the second conductors 32 are arranged in an alternating pattern along the first direction X.

[0161] Specifically, the first dimension is the length dimension, and the second dimension is the width dimension. The first dimension is larger than the second dimension, and the first conductor 31 and the second conductor 32 are located on the same side as the length dimensions of the first electrode 21 and the second electrode 22. Relatively speaking, the length dimension is larger. When the first conductor 31 and the second conductor 32 are arranged on the same side of the electrode assembly 200, not only does it have the above-mentioned effect of being arranged on the same side, but it also helps to separate the first conductor 31 and the second conductor 32, thereby avoiding the subsequent separation between the first conductor 31 and the second conductor 32 being too small, which would affect the subsequent assembly and connection.

[0162] Please refer to Figure 6 、 Figure 7 and Figure 8 In one embodiment, a first positioning groove 13 for installing the first conductor 31 and a second positioning groove 14 for installing the second conductor 32 are provided in the cavity 1. The first positioning groove 13 and the second positioning groove 14 are connected to the channel 17. The first conductor 31 has a first anti-rotation portion 311 extending into the cavity 1. The first anti-rotation portion 311 cooperates with the first positioning groove 13 to limit the circumferential rotation of the first conductor 31; the second conductor 32 specifically extends into the second anti-rotation portion 321 in the cavity 1. The second anti-rotation portion 321 cooperates with the second positioning groove 14 to limit the circumferential rotation of the second conductor 32.

[0163] In this embodiment, a first positioning groove 13 and a second positioning groove 14 may be provided on one side of the mounting groove 10 in the cavity 1 for mounting components such as the electrode assembly 200. The first positioning groove 13 is used to communicate with the channel 17 on the housing 100 for mounting the first conductor 31. The second positioning groove 14 is used to communicate with the channel 17 on the housing 100 for mounting the second conductor 32.

[0164] Specifically, a first anti-rotation portion 311 is provided at one end of the first conductor 31. The first anti-rotation portion 311 cooperates with the first positioning groove 13 to limit the circumferential rotation of the first conductor 31, thereby ensuring that when the part of the first conductor 31 extending out of the shell 100 is subsequently rotationally connected with other components, such as when a threaded connection is performed, the first conductor 31 can be reliably maintained in the circumferential direction.

[0165] Similarly, a second anti-rotation portion 321 is provided at one end of the second conductor 32. The second anti-rotation portion 321 cooperates with the second positioning groove 14 to limit the circumferential rotation of the second conductor 32, thereby ensuring that when the part of the second conductor 32 extending out of the shell 100 is subsequently rotationally connected with other components, such as when a threaded connection is performed, the second conductor 32 can be reliably maintained in the circumferential direction.

[0166] In a specific embodiment, the first anti-rotation portion 311 is a polygonal end portion provided at one end of the first conductor 31, and the circumferential profile of the first positioning groove 13 is adapted to the polygonal structure of the first anti-rotation portion 311; the second anti-rotation portion 321 is a polygonal end portion provided at one end of the second conductor 32, and the circumferential profile of the second positioning groove 14 is adapted to the polygonal structure of the second anti-rotation portion 321.

[0167] In this embodiment, the first anti-rotation portion 311 can be specifically a polygonal end portion provided at one end of the first conductor 31. For example, when the first conductor 31 is in the form of the above-mentioned bolt, the polygonal end portion is specifically a hexagonal nut. Of course, the specific structure of the polygonal end portion can also be in other forms, such as a regular quadrilateral, pentagon or irregular polygonal structure. Specifically, the shape structure of the polygonal end portion can also be in other forms and is not limited to the above description. Technicians in the relevant field may make other changes based on the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be included in the scope of protection of this application.

[0168] The circumferential profile of the first positioning groove 13 can be adapted to the polygonal structure of the first anti-rotation part 311. For example, when the polygonal structure of the first anti-rotation part 311 is a hexagon, the circumferential profile of the first positioning groove 13 can also be a hexagon. Of course, the circumferential profile of the first positioning groove 13 only needs to be able to constrain the first anti-rotation part 311 to rotate circumferentially, and it is not limited to the above examples. The way to achieve circumferential limitation between the first anti-rotation part 311 and the first positioning groove 13 is also not limited to the above examples. Technicians in the relevant field may make other changes based on the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be included in the scope of protection of this application.

[0169] Similarly, the circumferential profile of the second positioning groove 14 can be adapted to the polygonal structure of the second anti-rotation portion 321. For example, when the polygonal structure of the second anti-rotation portion 321 is a hexagon, the circumferential profile of the second positioning groove 14 can also be a hexagon. Of course, the circumferential profile of the second positioning groove 14 only needs to be able to constrain the second anti-rotation portion 321 to rotate circumferentially, and it is not limited to the above examples. The way to achieve circumferential limitation between the second anti-rotation portion 321 and the second positioning groove 14 is also not limited to the above examples. Technicians in the relevant field may make other changes inspired by the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be included in the scope of protection of this application.

[0170] In addition to cooperating with the first positioning groove 13 to achieve circumferential positioning, the first anti-rotation portion 311 also cooperates with the through hole to achieve axial positioning. Specifically, the outer contour of the first anti-rotation portion 311 is larger than the diameter of the through hole, thereby constraining the first anti-rotation portion 311 axially within the first positioning groove 13.

[0171] In addition to cooperating with the second positioning groove 14 to achieve circumferential positioning, the second anti-rotation portion 321 also cooperates with the through hole to achieve axial positioning. Specifically, the outer contour of the second anti-rotation portion 321 is larger than the diameter of the through hole, thereby constraining the second anti-rotation portion 321 axially within the second positioning groove 14.

[0172] like Figure 8 As shown, the control board assembly 400 can connect the conductive component to the outside. Specifically, the control board assembly 400 can include at least one substrate 40, which is provided with a first connection portion connected to the second portion of the conductive component and a second connection portion for connecting to the outside.

[0173] The first connection portion may include: a first opening 401 formed on the substrate 40 for inserting the first conductor 31, and a second opening 402 for inserting the second conductor 32. Generally, to ensure assembly reliability, especially to secure the substrate relative to the first conductor 31 and the second conductor 32, the ozone generator further includes a connection assembly for connecting the first conductor 31 and the second conductor 32 to the substrate, respectively.

[0174] like Figure 8 As shown, specifically, the first conductor 31 and the second conductor 32 are provided with external threads at positions where they cooperate with the substrate, and the connection assembly includes: at least one washer and a nut.

[0175] The first conductor 31 and the second conductor 32 may be in the form of the bolts exemplified above, and the portions thereof extending out of the cavity 1 may be provided with external threads. Accordingly, the connection assembly may include at least one washer and a nut. The washer may include at least one of a flat washer 451, a spring washer 452, or a combination thereof.

[0176] For example, taking the first conductor 31 as an example, along its axial extension, between the housing 100 and the substrate 40, the connection assembly may include: a flat washer 451, a spring washer 452, and a nut 453. The flat washer 451 is used to increase the contact area, thereby dispersing the pressure and preventing damage to the housing 100 when the bolt is tightened. The spring washer 452 can be used to generate a certain preload force to prevent the nut 453 from loosening. In the direction along the first conductor 31, in addition to achieving the connection function, the connection assembly can also form a certain spacing distance between the substrate 40 and the housing 100, thereby meeting the requirements for mounting electronic components on the substrate 40. Of course, the specific form of the connection assembly is not limited to the above example, and those skilled in the art can combine and arrange the connection assembly according to the needs of actual application scenarios.

[0177] Please refer to Figure 5 and Figure 8 In one embodiment, in order to improve the reliability of the connection between the connecting component and the substrate 40, the first connecting portion also includes: a conductive layer 47 provided on the substrate in a predetermined peripheral area near the first opening 401 and the second opening 402, and the connecting component is in contact with the conductive layer 47.

[0178] The conductive layer 47 can be a conductive ring disposed at the edges of the first opening 401 and the second opening 402. The conductive layer 47 can also cover the inner surfaces of the first opening 401 and the second opening 402. The size of the conductive ring can be adapted to the components of the connecting assembly with which it contacts. Specifically, the size of the conductive ring is greater than or equal to the contact area of the connecting component with which it is disconnected. For example, when the conductive ring contacts the nut, the outer diameter of the conductive ring is greater than or equal to the circumscribed diameter of the nut.

[0179] In addition, the specific structure of the conductive layer 47 is not limited to the above examples. It can also be adjusted according to the structure of the elements of the connecting assembly that cooperates with it, such as a multi-deformable structure, or a non-annular structure with partial openings, etc. This application does not make specific limitations here.

[0180] Please refer to Figure 1 、 Figure 8 and Figure 9 In one embodiment, the conductive component extends longitudinally as a whole along the third direction Z, and the control board assembly 400 includes a substrate. The substrate 40 includes a first substrate 41 and a second substrate 42 spaced apart along the third direction Z. The first substrate 41 is a substrate relatively close to the electrode assembly 200, and the second substrate 42 is a substrate relatively far away from the electrode assembly 200. The first substrate 41 and the second substrate 42 are electrically connected.

[0181] In this embodiment, the longitudinal extension direction of the conductive component, i.e., the axial direction, is arranged along a third direction Z. A first substrate 41 and a second substrate 42 may be spaced apart in this third direction Z. The first substrate 41 is relatively close to the electrode assembly 200, while the second substrate 42 is relatively far from the electrode assembly 200. Overall, by providing the first and second substrates 41, 42, the electronic components of the control board assembly 400 can be flexibly arranged on the first and second substrates 41, 42.

[0182] Specifically, the ozone generator may further include a connection assembly for connecting the first conductor 31 and the second conductor 32 to the second substrate 42 respectively. The first substrate 41 and the second substrate 42 are connected at opposite sides near the edge via a connector 43 .

[0183] In this embodiment, the second substrate 42 can be a substrate relatively far away from the electrode assembly 200, and the first conductor 31 and the second conductor 32 can be electrically connected to the second substrate 42 via a connecting assembly. Specifically, the connecting assembly can include at least one gasket and nut provided in the above embodiment. In addition, the first substrate 41 and the second substrate 42 can be connected via a connector 43. Specifically, the connector 43 can be in the form of a pin header. Of course, the connector 43 can also be in other forms, as long as it can achieve electrical connection between the first substrate 41 and the second substrate 42.

[0184] Furthermore, the connection assembly includes a top nut 454 located on the side of the second substrate 42 facing away from the first substrate 41. The first substrate 41 defines a first opening group 413 for receiving the first and second conductors 31, 32. The second substrate 42 defines a second opening group 423 for receiving the first and second conductors 31, 32. The aperture of the second opening group 423 is smaller than the circumscribed circle diameter of the top nut 454. A connection assembly is provided between the first substrate 41 and the housing 100. The composition and coordination of the connection assembly can be referred to the detailed description of the embodiment having a single substrate, and will not be further elaborated herein.

[0185] The first opening group 413 defined in the first substrate 41 can include two openings spaced a certain distance apart. The aperture of the second opening group 423 is smaller than that of the first opening group 413. Specifically, the aperture of the first opening group 413 is larger than the outer diameter of the connecting component, thereby enabling the connecting component to pass smoothly through the first opening group 413. For example, the openings of the first opening group 413 can be slightly larger than the outer diameter of a connecting component of the connecting component passing through the first opening group 413.

[0186] The second opening group 423 formed on the second substrate 42 may include two openings spaced a certain distance apart. The size of the openings may be slightly larger than the diameters of the first and second conductors 31 and 32, and smaller than the circumscribed diameter of the top nut 454. This ensures that the top nut 454 can reliably rest against the second substrate 42 while also ensuring a large contact area between the top nut 454 and the second substrate 42, thereby achieving reliable electrical connection.

[0187] like Figure 9 As shown, in one embodiment, the second connection portion is a wiring harness terminal 431 , which is provided on the first substrate 41 , and an avoidance groove 430 is provided on the second substrate 42 at a position directly opposite to the wiring harness terminal 431 .

[0188] In this embodiment, the second connection portion is mainly used to electrically connect the control board assembly 400 to the outside. Specifically, the second connection portion can be in the form of a wiring harness terminal. Of course, in this embodiment, it is not excluded that the second connection portion can be in other forms. Taking the second connection portion as a wiring harness terminal as an example, it can be set on the first substrate 41. In order to design the volume of the ozone generator to be miniaturized, when the distance between the first substrate 41 and the second substrate 42 is set to be smaller, for example, when the distance between the first substrate 41 and the second substrate 42 is smaller than the installation space required for the wiring harness terminal, a avoidance groove 430 can be opened on the second substrate 42 so that the wiring harness terminal passes through the avoidance groove 430 and can be reliably installed.

[0189] In one embodiment, the housing 100 has a mounting cavity 19 for mounting the control board assembly 400 on a side where the channel 17 is provided. The control board assembly 400 is at least partially located in the mounting cavity 19 .

[0190] In this embodiment, the housing 100 may be provided with a mounting cavity 19 on the side where the conductive component is led out. This mounting cavity 19 may specifically be a groove formed in the housing 100. The control board assembly 400 is at least partially located within this groove. Specifically, the groove may be configured to match the outer contour of the control board assembly 400, for example, in the form of a regular rectangular slot, thereby minimizing the space occupied by the groove and making the ozone generator more compact.

[0191] like Figure 5 As shown, to ensure the waterproof sealing performance of the control board assembly 400, a waterproof structure 46 is further provided between the mounting cavity 19 and the control board assembly 400. Specifically, the waterproof structure 46 may comprise any one of the following, or a combination thereof: a glue layer, a sealing cover, etc. For example, when the waterproof structure 46 is a glue layer, after the control board assembly 400 is installed in the mounting cavity 19, the space within the mounting cavity 19 may be filled with insulating glue, thereby forming a glue layer that covers the control board assembly 400. This glue layer not only ensures the waterproof sealing performance of the control board assembly 400, but also securely secures the control board assembly 400 in the mounting cavity 19. Of course, in addition to the aforementioned forms of waterproof structure 46, other forms of waterproof structure 46 may also be included. Persons skilled in the art may make other modifications based on the technical essence of this application. However, as long as the functions and effects achieved by such modifications are the same or similar to those of the present application, they are intended to be covered within the scope of protection of this application.

[0192] Overall, the miniaturized design of the ozone generator in various aspects of the present invention allows the size of the resulting ozone generator to be significantly reduced compared to existing ozone generators. Specifically, the dimensions of the housing 100 in length, width, and height are within 90 mm x 40 mm x 60 mm.

[0193] In some embodiments, the control board assembly 400 may include: a plate-shaped substrate 40 and a functional circuit disposed on the substrate 40 , wherein the functional circuit includes any one or a combination of the following: an inverting circuit, a current detection circuit, and a voltage regulating circuit.

[0194] In this embodiment, the control board assembly 400 may include a plate-shaped substrate 40 and functional circuits. Specifically, the substrate 40 may be a printed circuit board (PCB). The PCB includes an insulating base, connecting wires, and pads. Electronic components are soldered onto the PCB to achieve circuit connections and corresponding functions.

[0195] Specifically, the functional circuit can be configured with different functions depending on the scenario in which the ozone generator is used, for example, it can include any one or a combination of a polarity reversal circuit, a current detection circuit, and a voltage regulation circuit. Of course, the functional circuit is not limited to the above examples, and the embodiments of this application only illustrate a few typical embodiments.

[0196] For example, in one embodiment, the functional circuit may include a reversing circuit. When the reversing circuit is connected to a power supply, the reversing circuit can apply a predetermined voltage to the electrode assembly 200 and switch the current flow direction of the electrodes in the electrode assembly 200 in a predetermined manner.

[0197] When the ozone generator is in use, the reversal circuit is provided to perform reversal, thereby preventing scaling and extending its service life. Specifically, the reversal circuit is configured such that: when the reversal circuit is in a first state, the first electrode 21 is a positive electrode, the second electrode 22 is a negative electrode, and current flows from the first electrode 21 to the second electrode 22; when the reversal circuit is in a second state, the first electrode 21 is a negative electrode, the second electrode 22 is a positive electrode, and current flows from the second electrode 22 to the first electrode 21.

[0198] The specific configuration of the inverting circuit may include: MOS tubes, relays, or other forms of components with switching functions. Of course, the specific configuration of the inverting circuit is not limited to the above description. Persons skilled in the art may make other changes based on the technical essence of this application. However, as long as the functions and effects achieved are the same or similar to those of this application, they should be included in the scope of protection of this application. Taking the relay as an example, when its contacts are in the first connection position and connected to the first circuit, the inverting circuit is in the first state; when its contacts are in the second connection position and connected to the second circuit, the inverting circuit is in the second state.

[0199] In this embodiment, a constant voltage (e.g., 24V, 12V, 36V) is input externally to the ozone generator, and the electrode assembly 200 of the ozone generator can generate ozone water with an ozone concentration that meets the preset concentration requirements when working without the need to monitor and adjust the current, thereby eliminating the current regulation circuit set in the prior art to ensure the concentration of ozone water.

[0200] In one embodiment, the conductive component extends longitudinally along a third direction Z. The control board assembly 400 includes a substrate 40, which includes a first substrate 41 and a second substrate 42 spaced apart along the third direction Z. The first substrate 41 has a first surface 411 facing the electrode assembly 200 and a second surface opposite the first surface 411. The second substrate 42 has a third surface 421 facing the second surface and a fourth surface opposite the third surface 421. The inverted circuit is provided on any one or a combination of the following surfaces: the first surface 411, the second surface, and the third surface 421.

[0201] like Figure 9 As shown, taking the substrate 40 including the first substrate 41 and the second substrate 42 as an example, since the second substrate 42 is located on the side away from the electrode assembly 200, a top nut 454 needs to be provided on its fourth surface. When installing the top nut 454, it may contact the electronic components on the second substrate 42, thereby affecting the reliability of the electronic components.

[0202] To ensure the reliability of the electronic components in the inversion circuit, the inversion circuit can be provided on at least one of the first surface 411, the second surface, and the third surface 421, while avoiding the fourth surface. Furthermore, for the embodiment in which the second connection portion is provided on the first substrate 41, the inversion circuit can be provided on the first surface 411 and / or the second surface, thereby further ensuring the reliability of the circuit connection.

[0203] In one embodiment, the functional circuit further includes a current detection circuit, and the current detection circuit is used to detect the operating current of the electrode assembly 200 .

[0204] In this embodiment, a current detection circuit is provided to detect the working current of the electrode assembly 200, which can be used as a feedback signal to determine the current water quality. Based on the current water quality, the duration / frequency of the polarity reversal can be flexibly adjusted.

[0205] For different water qualities, the worse the water quality, the more calcium and magnesium ions in the water, the more likely it is to quickly form scale on the electrode surface. At the same voltage, the current detection circuit can detect a larger current. In this case, to prevent scaling on the electrode surface, the reversal time can be shortened. Conversely, the better the water quality, the less calcium and magnesium ions in the water, the less likely it is to quickly form scale on the electrode surface. At the same voltage, the current detection circuit can detect a smaller current. In this case, to prevent scaling on the electrode surface, the reversal time can be extended.

[0206] like Figure 9 As shown, specifically, the conductive component extends longitudinally along the third direction Z as a whole, and the control board assembly 400 includes a substrate 40, and the substrate 40 includes a first substrate 41 and a second substrate 42 spaced apart along the third direction Z, the first substrate 41 having a first surface 411 facing the electrode assembly 200 and a second surface opposite to the first surface 411, the second substrate 42 having a third surface 421 facing the second surface and a fourth surface opposite to the third surface 421, the current detection circuit is arranged on the third surface 421, and the inverting circuit is arranged on the first surface 411 and / or the second surface.

[0207] In this embodiment, the reason why the current detection circuit is not disposed on the fourth surface can be compared to the reason why the inversion circuit is not disposed on the fourth surface. In addition, the current detection circuit is further optimized in terms of function compared to the inversion circuit. Therefore, the inversion circuit, which has a more basic and important function, can be disposed on the first surface 411 and / or the second surface. Even if the connecting component (e.g., the pin header) between the second substrate 42 and the first substrate 41 subsequently fails, the normal operation of the inversion circuit will not be affected.

[0208] In one embodiment, the second connection portion is electrically connected to an external preset controller, and the preset controller can provide a predetermined voltage or voltage signal to the control board assembly 400 .

[0209] In this embodiment, as described above, when the ozone generator receives an external constant voltage (e.g., 24V, 12V, or 36V), its electrode assembly 200 can produce ozone water with an ozone concentration that meets a preset concentration requirement during electrolysis without the need to monitor or adjust the current. The constant voltage (i.e., the predetermined voltage) can be directly provided by an external controller, or the external controller can provide a voltage signal, and the voltage regulator circuit on the control board assembly 400 can adjust the external input voltage based on the voltage signal to achieve the predetermined voltage.

[0210] In one embodiment, the functional circuit may further include a voltage regulating circuit. After the second connection portion is electrically connected to a preset controller, the preset controller may output a predetermined voltage to the conductive component through the voltage regulating circuit of the control board assembly 400 .

[0211] In this embodiment, the functional circuit may include a voltage regulating circuit, which can regulate the voltage input from the preset controller to reach a predetermined voltage, thereby applying it to the electrode assembly 200 .

[0212] In one embodiment, the second connection portion is electrically connected to an external preset controller, and the preset controller can provide a polarity reversal signal to the control board assembly 400 .

[0213] In an embodiment of the present application, a water system is further provided, comprising: the ozone generator described in the above embodiment. By providing the ozone generator, the water system can achieve the technical effects achieved by the ozone generator embodiment. For details, please refer to the detailed description of the above embodiment, and this application will not repeat them here.

[0214] In some embodiments, the water system may further include: a host, the host being provided with a controller, the controller being connectable to the second connection portion; and a water passage for passing water, wherein at least part of the water flowing through the water passage can pass through the ozone generator.

[0215] In this embodiment, the specific form of the water system can be any form that requires the use of ozone water. Specifically, the water system can include any one or a combination of the following: a water heater, a water purifier, a dishwasher, and a steam oven. Of course, the specific form of the water system is not limited to the above examples.

[0216] The water system is provided with a host computer. The specific form of the host computer may vary depending on the form of the host system and is not specifically limited herein. The host computer is provided with a controller, which is connected to the second connection portion and can serve as the preset controller mentioned in the above-mentioned ozone generator embodiment. The controller can output a predetermined voltage or a predetermined voltage signal to the control board assembly 400.

[0217] The water system also includes a water channel for passing water. The ozone generator can be connected to the water channel. When the water in the water flow passes through the ozone generator and the starting conditions for preparing ozone are met, the ozone generator can be started to prepare ozone water.

[0218] Furthermore, the water system may include a voltage regulating circuit, which is disposed in the controller or the control board assembly 400 .

[0219] The function of the voltage regulating circuit can be referred to in detail in the above-mentioned embodiment of the ozone generator, and will not be further described here. If the controller is provided with a voltage regulating circuit, the control board assembly 400 can directly utilize the voltage regulating circuit in the controller to achieve voltage regulation without the need for a voltage regulating circuit, thereby simplifying the control board assembly 400 and reducing the size and cost of the ozone generator.

[0220] In a specific scenario, for example, when the ozone generator is used in a water purifier, when the water flowing into the ozone generator is purified water, the ions such as calcium and magnesium contained in the water that are prone to scale formation have been filtered and processed by the filter element in the water purifier. Therefore, when the ozone generator is powered on, scale is not easily generated, and there is no need to set up a reversal circuit. At this time, only a voltage regulating circuit needs to be set up in the controller or control board assembly 400. The electrode used as the anode in the ozone generator can be provided with the coating material described in the above embodiment (for example, any one of a boron-doped diamond electrode, a tin dioxide electrode, a lead dioxide electrode, and a platinum electrode), and the electrode used as the cathode does not need to be provided with the above coating, and its material can be selected from stainless steel, titanium, etc. with lower cost.

[0221] In one embodiment, the control board assembly 400 may include a reversing circuit. When the controller is electrically connected to the control board assembly 400, the controller can apply a predetermined voltage to the electrode assembly 200 through the reversing circuit, thereby switching the current flow direction of the electrodes in the electrode assembly 200 in a predetermined manner. The reversing circuit can be described in detail with reference to the above-mentioned embodiment of the ozone generator, and will not be further described herein.

[0222] In this embodiment, the structure and function of the inversion circuit itself can refer to the detailed description of the above-mentioned ozone generator embodiment. Unlike the above-mentioned embodiment, the inversion circuit is provided in the controller. When the inversion circuit is provided in the controller, the inversion circuit in the ozone generator can be omitted, thereby simplifying the control board assembly 400 and reducing the size and cost of the ozone generator.

[0223] Furthermore, the water system includes a current detection circuit, and the controller or the control board assembly 400 is configured to adjust the inversion time / frequency according to the working current of the electrode assembly 200 detected by the current detection circuit.

[0224] In this embodiment, the water system may further include a current detection circuit, wherein the function of the current detection circuit itself may refer to the specific description of the above-mentioned ozone generator embodiment. When the current detection circuit is provided in the water system, the current detection circuit can be omitted compared to the ozone generator originally provided with the current detection circuit, thereby simplifying the control board assembly 400 and reducing the volume and cost of the ozone generator.

[0225] The inversion duration of the electrode assembly 200 can be adjusted based on the result of the current detection circuit. The specific control logic for adjusting the inversion duration can be stored in the controller or in the control board assembly 400. When the control logic is stored in the controller, the control board assembly 400 can be simplified, reducing the size and cost of the ozone generator.

[0226] The operating current applied to the electrode assembly 200 by the inverting circuit is between 0.6 A and 3 A. Within the above operating current range, the electrode assembly 200 can stably and reliably produce ozone water with a concentration that meets the use requirements when working.

[0227] In one embodiment, the water system may further include: a detection component, which is electrically connected to the controller, and the detection component includes a first detection component for obtaining a user water use signal, and the controller is configured to: when the first detection component detects a user water use signal, control the power supply to provide a predetermined voltage or voltage signal to the control panel assembly 400.

[0228] To ensure user safety, before starting the ozone generator, you can first obtain the user's water usage signal to ensure that the user is using water normally before starting the ozone generator to prevent the electrode from working without water, causing damage and safety problems, such as short circuit, combustion and other problems.

[0229] Specifically, the water system itself can be provided with a detection component, which can include a first detection component for obtaining a user's water usage signal. The ozone generator can use the first detection component to determine whether it can be started at present, which is equivalent to omitting the flow detection component and the corresponding functional circuit inside the ozone generator, thereby reducing the size of the shell 100 and simplifying the control panel assembly 400, thereby further reducing the volume and cost of the ozone generator.

[0230] Wherein, the first detection part may include any one of the following or a combination thereof: a flow detection part, a flow switch, a control valve arranged in the waterway or connected to the waterway, an operating part (starting unit). Of course, the specific form of the first detection part is not limited to the above examples. Generally, for a water system, a flow detection part is generally provided, and the flow rate currently flowing through the ozone generator can be accurately obtained by using the flow detection part, so as to judge whether the flow rate flowing through the ozone generator reaches the safe flow rate for starting the ozone generator according to the control logic of the controller. If it reaches, the ozone generator can be started.

[0231] In one embodiment, the detection element may further include a second detection element, which includes any one of the following or a combination thereof: a flow detection element, a temperature detection element, and the controller is configured to determine the predetermined voltage based on the current flow detected by the flow detection element and / or the temperature detected by the temperature detection element.

[0232] In this embodiment, the detection component may further include a second detection component that cooperates with the control to further increase the predetermined voltage applied to the ozone generator. Although the voltage applied to the electrode assembly 200 is a constant voltage, the specific value of this constant voltage can be optimized based on the operating conditions of the ozone generator. The predetermined voltage ranges from 12V to 36V.

[0233] For example, for an ozone generator, the flow rate and temperature of the water flowing through it have different specific values in different scenarios, and the temperature and flow rate of the water flow have a certain impact on the concentration of the ozone water actually produced by the ozone generator. To take into account the above flow rate and temperature parameters, the ozone generator can use the flow detection and / or temperature detection components in the water system to accurately match the predetermined voltage applied to the electrode assembly 200. Since the ozone generator itself does not add any components or circuits, the size and cost of the ozone generator will not increase.

[0234] Furthermore, the second detection element may further include a water quality detection element. The water quality detection element is used to obtain a water quality signal, the water quality signal includes a TDS signal, and the predetermined voltage is proportional to the TDS value represented by the TDS signal.

[0235] For an ozone generator, the water quality of the water flowing through it varies in different scenarios, and this water quality has a certain impact on the ozone concentration and reversal duration of the ozone generator. To take these water quality parameters into account, the ozone generator can use the water quality detection components in the water system to accurately match the predetermined voltage applied to the electrode assembly 200 and adjust the reversal duration. Since the ozone generator itself does not have any additional components or circuits, the size and cost of the ozone generator will not increase.

[0236] Specifically, the controller may pre-store an initial TDS value representing water quality and an initial predetermined voltage corresponding to the initial TDS value. The controller is configured to determine the current predetermined voltage based on the current TDS value representing the current water quality obtained by the water quality detection component, the initial TDS value, and the initial predetermined voltage. For example, a correction coefficient may be determined by combining the obtained current TDS value and the initial TDS value, and the initial predetermined voltage may be corrected using the correction coefficient to obtain the current predetermined voltage.

[0237] In one embodiment, the second detection element includes a flow detection element and a temperature detection element, and the controller stores a first correspondence between the flow rate, temperature and the predetermined voltage under different water quality conditions; the controller is configured to determine the predetermined voltage under the current flow rate and current temperature conditions based on the water quality detected by the water quality detection element, the current flow rate detected by the flow detection element, the current temperature detected by the temperature detection element and the first correspondence.

[0238] In this embodiment, the second detection component may include: a flow detection component, a temperature detection component, and a water quality detection component. Wherein, when determining the predetermined voltage, the controller may first determine the initial predetermined voltage in a first correspondence based on the current flow detected by the flow detection component and the current temperature detected by the temperature detection component. Further, a correction coefficient is determined in combination with the current TDS water quality and the initial TDS water quality in the controller, and the initial predetermined voltage is corrected using the correction coefficient to obtain the current predetermined voltage. Wherein, the specific form of the first corresponding relationship may be in the form of a table or a function, etc., and the specific application does not make a sole limitation here.

[0239] In one embodiment, the second detection component may further include a timing module for detecting the working time of the electrode.

[0240] The controller stores a second correspondence between the flow rate, temperature, the working time of the electrode and the predetermined voltage under different water quality conditions; the controller is configured to determine the predetermined voltage under the conditions of the current flow rate, current temperature and current working time of the electrode based on the water quality detected by the water quality detection component, the current flow rate detected by the flow detection component, the current temperature detected by the temperature detection component, the working time of the electrode detected by the timing module and the second correspondence.

[0241] In this embodiment, the main difference from the above embodiment is that the working time of the electrode is added in the second corresponding relationship. Overall, the control logic of the controller is similar to that of the above embodiment. When the working time of the electrode is increased, a predetermined voltage can be provided specifically for the case of electrodes with different working times, meeting the usage needs in scenarios where the working time of the above electrodes needs to be adjusted.

[0242] In some embodiments, the water system may further include: a housing; the ozone generator is disposed inside the housing, or the ozone generator is disposed outside the housing, or the ozone generator is disposed on the housing.

[0243] In this embodiment, the water system is provided with a corresponding housing, and the position of the ozone generator relative to the housing is not limited. For example, the ozone generator may be pre-installed within the housing, mounted on the housing, or mounted externally. For example, the ozone generator may be an optional feature of the water system, allowing for flexible selection based on user needs. If the user desires to configure the ozone water function, the ozone generator may be installed within the water system.

[0244] Furthermore, a water inlet and a water outlet are provided on the shell, the inlet 11 can be connected to the water inlet, the outlet 12 is located upstream of the water outlet, or the outlet 12 is integrated with the water outlet; or, the ozone generator is provided downstream of the water outlet, and the inlet 11 is connected to the water outlet.

[0245] When the ozone generator is used in a water system, its installation location can vary depending on the function of the water system that requires the use of ozone water, and this application does not make specific restrictions here. For example, for a water heater, it can be installed at the water outlet of the shell or in the pipeline upstream of the water outlet. When the hot water generated by the water heater meets the user's preset temperature and flows out, it flows through the ozone generator, thereby generating hot ozone water. For example, for a dishwasher, the ozone generator can be installed at the water inlet or in the pipeline upstream of the water inlet. Water supplied from an external water source flows through the ozone generator to generate ozone water for the dishwasher to clean.

[0246] It should be noted that, in the description of this application, the terms "first," "second," etc., are used solely for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, nor should they be understood to indicate or imply relative importance. Furthermore, in the description of this application, unless otherwise specified, "plurality" means two or more.

[0247] The above-mentioned various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0248] The above are only a few embodiments of the present invention. Although the embodiments disclosed in the present invention are as above, the contents are only for the purpose of facilitating the understanding of the present invention and are not intended to limit the present invention. Any person skilled in the art of the present invention may make any modifications and changes in the form and details of the embodiments without departing from the spirit and scope disclosed in the present invention. However, the scope of patent protection of the present invention shall still be based on the scope defined by the appended claims.
