Description

Technical Field

[0001] This invention relates to the field of ozone water generation technology, and particularly to an ozone generator and water system. Background Technology

[0002] Ozone, composed of three oxygen atoms, is a natural and powerful oxidant and bactericide. The ozone layer in the atmosphere absorbs harmful ultraviolet radiation from sunlight, protecting life on Earth. High-purity ozone produced industrially is widely used as a substitute for chlorine disinfection in tap water treatment, packaged water, pharmaceutical manufacturing, and food processing. Ozone in water has bactericidal, oxidizing, decolorizing, deodorizing, and advanced oxidizing functions. The hydroxyl groups produced when ozone decomposes in water have strong oxidizing power, rapidly decomposing iron, manganese, odors, bacteria, and viruses in the water, and eliminating chlorine or trihalomethanes in tap water.

[0003] Currently, a typical method for ozone generation is electrolysis. When preparing ozone water using electrolysis, an ozone generator is usually installed. The basic structure of this ozone generator includes an anode, a cathode, and a membrane sandwiched in between that acts as a proton exchanger. When water flows into the ozone generator, electrolysis extracts oxygen from the water molecules, which then combines to form ozone molecules. This method produces ozone with high purity and concentration, meeting the needs for sterilization, detoxification, preservation, deodorization, and bleaching.

[0004] Existing technologies also provide some ozone generators; however, existing ozone generators have considerable room for improvement and optimization in many aspects (such as miniaturization and versatility).

[0117] The first electrode 21 may include any one of boron-doped diamond electrode, tin dioxide electrode, lead dioxide electrode, and platinum electrode. The material of the first electrode 21 may be a noble metal oxide. Besides the materials listed above (boron-doped diamond electrode, tin dioxide electrode, lead dioxide electrode, and platinum electrode), this application does not exclude the use of other noble metal oxide materials for the first electrode 21. Overall, the material selection for the first electrode 21, while meeting the requirements of reliability and safety, can be based on materials with long service life and relatively low cost.

[0118] A through-hole 210 is provided on the first electrode 21 along its thickness direction. The proton exchange membrane 23 is a complete sheet without any pores. When the first electrode 21 is the anode, the pores 210 can be used to increase 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 pores 210 on the first electrode 21 facilitates the efficient outward discharge of ozone water generated at the three-phase interface between the first electrode 21, water, and the proton exchange membrane 23 towards the side away from the proton exchange membrane 23.

[0119] The shape, structure, size, and distribution of the pores 210 on the first electrode 21 can vary depending on the direction of water flow, the structure of the first electrode 21, and the performance requirements of the ozone generator. For example, Figure 10 As shown, the first electrode 21 can be a rectangular structure with opposite length and width directions. The dimension of the first electrode 21 in the length direction is larger than the dimension in the width direction. The aperture 210 can be a strip-shaped aperture extending along the width direction, and there can be multiple strip-shaped apertures arranged at intervals along the length direction. Specifically, the strip-shaped aperture can be a rectangular aperture with equal width, or it can be an oblong aperture with unequal width, etc.

[0120] When water enters the cavity 1 from the inlet 11, it flows through the first electrode 21. Since the direction of water flow forms a certain angle with the direction of extension of the pore 210, for example, it is roughly perpendicular, which can directly flush the pore 210, thus making it easier to carry away the generated ozone water and output it through the outlet 12.

[0121] For the first electrode 21, a coating is provided on its first inner surface facing the proton exchange membrane 23. Specifically, this coating may be a noble metal oxide layer deposited by means of deposition. The noble metal oxide layer will be gradually consumed during use. Theoretically, the surface area of ​​the noble metal oxide layer is proportional to its service life.

[0122] Meanwhile, for the first electrode 21 with pores 210, the perimeter of the pores 210 is beneficial to increasing the perimeter of the three-phase interface when the first electrode 21 is used as the anode, thereby improving the efficiency of the electrolysis reaction. Theoretically, the longer the perimeter of the three-phase interface is increased by setting the pores 210, the better the effect on improving the efficiency of the electrolysis reaction.

[0123] Considering the lifespan of the first electrode 21 and the efficiency requirements for its electrolytic reaction as an anode, the effective area of ​​the first electrode 21, excluding the pores 210, can account for 15% to 95% of its total surface area.

[0124] Specifically, the coating thickness is between 2µm and 15µm. In this application, the coating is provided on the first inner surface of the first electrode 21 and the second inner surface of the second electrode 22. The thicker the coating, the longer the lifespan of the electrode is theoretically. In the embodiments of this application, it has been verified that the coatings provided on the first electrode 21 and the second electrode 22 can at least meet the requirement that the ozone generator outputs ozone water that meets the usage requirements.

[0125] For the first electrode 21 and the second electrode 22, which have a plate-like structure, and the proton exchange membrane 23, which has a sheet-like structure, the first inner surface of the first electrode 21 is attached to one surface of the proton exchange membrane 23, and the second inner surface of the second electrode 22 is attached to the other surface of the proton exchange membrane 23. This assembly ensures sufficient contact between the first electrode 21 and the second electrode 22 and the proton exchange membrane 23, and also helps to reduce the size in the thickness direction of the laminate.

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

[0127] In this configuration, the first inner surface of the first electrode 21 is bonded to one of the surfaces of the proton exchange membrane 23. This assembly ensures surface contact between the first electrode 21 and the proton exchange membrane 23. When the first electrode 21 and the proton exchange membrane 23 are bonded together to form surface contact, a three-phase interface is formed between the coating of the first electrode 21, water, and the proton exchange membrane 23 at the periphery of the first electrode 21, the proton exchange membrane 23 in contact with water, and the periphery with the pores 210. Overall, the electrolytic reaction begins at the outermost edge of the bond, and as the reaction time increases, the coating gradually and slowly dissolves from the edge inwards, thereby extending the service life of the first electrode 21.

[0128] Furthermore, for the first electrode 21 with pores 210, during use, the perimeter of the entire coating of the first electrode 21 gradually decreases, while the perimeter of the pores 210 gradually increases. The increase in the perimeter of the pores 210 can compensate for the decrease in the perimeter of the entire first electrode 21, thereby helping to ensure that the first electrode 21 always has a high electrolysis reaction efficiency when used as an anode.

[0129] Furthermore, the technical effect that can be produced by the second inner surface of the second electrode 22 being attached to the other surface of the proton exchange membrane 23 can be referred to as the technical effect produced by the first inner surface of the first electrode 21 being attached to the other surface of the proton exchange membrane 23, which will not be repeated here.

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

[0131] 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, wherein a first part of the first conductor 31 is connected to the first electrode 21, a first part of the second conductor 32 is connected to the second electrode 22, and a second part of both the first conductor 31 and the second conductor 32 are 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 may 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 compared with the first conductor 31.

[0133] Specifically, the first conductor 31 can be entirely cylindrical, with a portion extending through the housing 100. The conductor includes a first portion located inside 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 it can also take other specific forms. Taking the bolt-shaped first conductor 31 as an example, it can include a nut, a smooth section, and a threaded section, wherein the nut portion is located inside the cavity 1, the threaded section can be located outside the cavity 1, and the smooth section can be partially inside and partially outside the cavity 1.

[0134] Please refer to the following: Figure 7 and Figure 8Furthermore, a 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 that contacts the first outer surface and a first connection transition portion 332 that connects the first electrode contact portion 331 to the first portion of the first conductor 31. Similarly, a 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 that contacts the second outer surface and a second connection transition portion 342 that connects 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 connecting transition portion 332. Of course, the first electrode contact portion 331 and the first connecting transition portion 332 can also be connected in other ways, such as by welding for a fixed connection or by threaded connection for a detachable connection. When the first electrode contact portion 331 and the first connecting transition portion 332 are integrally formed, it is beneficial to the miniaturization of the structure, reduce the processing and manufacturing cost, and at the same time ensure 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 also be integrally formed, which is beneficial for miniaturization of the structure, reduces manufacturing costs, and ensures the reliability of the connection position.

[0138] The first electrode contact portion 331 is a sheet-like frame surrounding the edge of the first outer surface. One end of the first connecting 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 can be a hollow frame structure, and its outer contour can 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 can be a rectangular frame. Of course, the structure of the first electrode 21 and the specific structure of the first electrode contact portion 331 can also be other shapes. This application does not specifically limit their structure. In the embodiments and drawings of this application, the first electrode contact portion 331 is a rectangular frame when the outer contour of the first electrode 21 is rectangular, which is mainly used as an example for illustration.

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

[0141] Specifically, the first connection transition portion 332 is provided with a first opening at one end connected to the first part of the first conductor 31, and the first part of the first conductor 31 passes 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 conductor 31 is bolt-shaped, the other end of the first connecting transition portion 332 can be provided with a first sleeve hole that matches the smooth section of the bolt. The bolt can be inserted into the first sleeve hole, thereby ensuring that the first connecting transition portion 332 and the first conductor 31 maintain reliable contact. In addition, the first connecting transition portion 332 can also be fixed to the first part of the first conductor 31 in other ways, such as by welding, or the first connecting transition portion 332 can be integrally formed with the first part of the first conductor 31. Specifically, this application does not make a unique limitation.

[0143] Similarly, the second electrode contact portion 341 is generally a sheet-like frame surrounding the edge of the second outer surface. One end of the second connecting transition portion 342 is connected to the second electrode contact portion 341, and the other end is connected to the second part of the second conductor 32. Specifically, the end of the second connecting transition portion 342 connected to the first part of the second conductor 32 is provided with a second sleeve hole, and the first part of the second conductor 32 passes through the second sleeve hole. Alternatively, the second connecting transition portion 342 is fixedly connected to the first part of the second conductor 32 or integrally formed.

[0144] In one 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. Along the depth direction of 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 sequentially.

[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 with a predetermined depth can be provided in 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 in 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. 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. Furthermore, the circumferential inner contour dimension of the mounting groove 10 can also be equal or nearly equal to that 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. This arrangement not only allows for reliable circumferential positioning 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 using the mounting groove 10, but also minimizes the size of the cavity 1, 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 disposed between the second electrode contact portion 341 and the second housing 120. When the second housing 120 is sealed to the first housing 110, the buffer 44 is in a compressed state.

[0147] In this embodiment, the buffer 44 can be a deformable sheet-like component with a predetermined thickness.

[0148] The buffer element 44 can be made of a flexible material. Specifically, the material of the buffer element 44 can include insulating rubber or an insulating spring. For example, the material of the buffer element 44 can be insulating rubber. When the buffer element 44 is made of insulating rubber, on the one hand, it can utilize the deformability of rubber to produce the aforementioned buffering effect; on the other hand, the buffer element 44 can also serve as an insulating protective component, improving the compactness of the ozone generator structure and 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 contact the second electrode contact portion 341 and the second housing 120, while the thinner middle portion can directly face the pores 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 with pores 210 is not completely blocked by the buffer 44, especially the area with pores 210. When water enters through the inlet 11, it can flow through this gap into the area where the electrode has pores 210, thereby carrying away the ozone water with a higher concentration in the pores 210 area and outputting it to the user's water terminal.

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

[0151] To limit the movement of the buffer 44, particularly in the circumferential direction, multiple limiting portions 16 can be provided within the cavity 1. The number and form of these limiting portions 16 can be adapted to the shape and structure of the buffer 44. For example, when the buffer 44 is a rectangular sheet structure, limiting holes can be provided at each of its four corners. Correspondingly, the limiting portions 16 can take the form of multiple small protrusions formed on the inner wall of the cavity 1, the position and size of which are adapted to the position and size of the limiting holes.

[0152] Of course, the specific arrangement of the limiting part 16 can also be in other ways, and is not limited to the above description. Those skilled in the art may make other changes under the guidance of the technical essence of this application, but as long as the function and effect achieved are the same as or similar to 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, thereby meeting 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. The notch 18 is used to lead out the first connecting transition portion 332 of the first component 33 and the second connecting transition portion 342 of the second component 34, so as to connect different conductors (first conductor 31 and second conductor 32).

[0156] To prevent the first connecting transition portion 332 and the second connecting transition portion 342 from contacting each other during use and forming a short circuit, thereby affecting the reliability of the ozone generator, a blocking member 15 can be provided inside the cavity 1 to isolate the first connecting transition portion 332 and the second connecting transition portion 342. Specifically, the blocking member 15 can be a baffle strip with a certain height set on the inner wall of the cavity 1. Of course, the specific structure of the blocking member 15 can be adapted to the specific layout and position of the first connecting transition portion 332 and the second connecting transition portion 342, etc., and this application does not make a unique limitation. The blocking member 15 can be formed in the cavity 1 by integral injection molding, which can simplify the structure, reduce costs, and ensure the reliability of the fit 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 method where 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, thereby helping to reduce the volume of the ozone generator and make it more miniaturized.

[0159] Please refer to the following: Figure 1 , Figure 2 , Figure 5 and Figure 6 Specifically, in the 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 the 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 along the 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 along the second direction Y perpendicular to the first direction X. The first size may be greater than or equal to the second size, or it may be smaller than the second size. The first conductor 31 and the second conductor 32 are arranged at intervals 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. The first conductor 31 and the second conductor 32 are located on the same side of the length dimension of the first electrode 21 and the second electrode 22. Relatively speaking, the dimension in the length direction 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 is the above-mentioned arrangement on the same side achieved, but it also helps to separate the first conductor 31 and the second conductor 32, avoiding the subsequent assembly connection being affected by the spacing between the first conductor 31 and the second conductor 32 being too small.

[0162] Please refer to the following: Figure 6 , Figure 7 and Figure 8 In one embodiment, the cavity 1 is provided with a first positioning groove 13 for installing the first conductor 31 and a second positioning groove 14 for installing the second conductor 32. 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 part 311 extending into the cavity 1. The first anti-rotation part 311 cooperates with the first positioning groove 13 to restrict the circumferential rotation of the first conductor 31. The second conductor 32 specifically extends into the cavity 1 with a second anti-rotation part 321. The second anti-rotation part 321 cooperates with the second positioning groove 14 to restrict 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 inside 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 and is used to mount the first conductor 31. The second positioning groove 14 is used to communicate with the channel 17 on the housing 100 and is used to mount the second conductor 32.

[0164] Specifically, one end of the first conductor 31 is provided with a first anti-rotation part 311. The first anti-rotation part 311 cooperates with the first positioning groove 13 to restrict the circumferential rotation of the first conductor 31. This ensures that when the part of the first conductor 31 extending out of the housing 100 is rotated and connected to other components, such as when a threaded connection is made, the first conductor 31 can be reliably maintained in the circumferential direction.

[0165] Similarly, one end of the second conductor 32 is provided with a second anti-rotation part 321. The second anti-rotation part 321 cooperates with the second positioning groove 14 to restrict the circumferential rotation of the second conductor 32. This ensures that when the part of the second conductor 32 extending out of the housing 100 is rotatably connected to other components, such as when a threaded connection is made, the second conductor 32 can be reliably maintained in the circumferential direction.

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

[0167] In this embodiment, the first anti-rotation part 311 can specifically be a polygonal end portion disposed at one end of the first conductor 31. For example, when the first conductor 31 is in the form of a bolt, the polygonal end portion is specifically a hexagonal nut. Of course, the specific structure of the polygonal end portion can also be other forms, such as a regular quadrilateral, pentagon, or irregular polygonal structure. Specifically, the shape and structure of the polygonal end portion can also be other forms, and are not limited to the above description. Those skilled in the art may make other modifications under the guidance of the technical essence of this application, but as long as the function and effect achieved are the same as or similar to those of this application, they should all be covered within the protection scope of this application.

[0168] The circumferential contour 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 hexagonal, the circumferential contour of the first positioning groove 13 can also be hexagonal. Of course, the circumferential contour 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 example. The way in which the first anti-rotation part 311 and the first positioning groove 13 achieve circumferential limiting is also not limited to the above example. Those skilled in the art may make other changes under the guidance of the technical essence of this application, but as long as the function and effect achieved are the same as or similar to those of this application, they should be covered within the protection scope of this application.

[0169] Similarly, the circumferential contour of the second positioning groove 14 can be adapted to the polygonal structure of the second anti-rotation part 321. For example, when the polygonal structure of the second anti-rotation part 321 is hexagonal, the circumferential contour of the second positioning groove 14 can also be hexagonal. Of course, the circumferential contour of the second positioning groove 14 only needs to be able to constrain the second anti-rotation part 321 to rotate circumferentially, and it is not limited to the above examples. The way in which the second anti-rotation part 321 and the second positioning groove 14 achieve circumferential limiting is also not limited to the above examples. Those skilled in the art may make other changes under the guidance of the technical essence of this application, but as long as the function and effect achieved are the same as or similar to those of this application, they should be covered within 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 part 311 can also achieve axial positioning by cooperating with the through hole. Specifically, the outer contour dimension of the first anti-rotation part 311 is larger than the diameter of the through hole, so that the first anti-rotation part 311 is constrained in the first positioning groove 13 in the axial direction.

[0171] In addition to cooperating with the second positioning groove 14 to achieve circumferential positioning, the second anti-rotation part 321 can also achieve axial positioning by cooperating with the through hole. Specifically, the outer contour dimension of the second anti-rotation part 321 is larger than the diameter of the through hole, so that the second anti-rotation part 321 is constrained in the second positioning groove 14 in the axial direction.

[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 may include at least one substrate 40, on which a first connection portion connected to a second portion of the conductive component and a second connection portion for connecting to the outside are provided.

[0173] The first connecting portion may include a first opening 401 for the first conductor 31 to pass through and a second opening 402 for the second conductor 32 to pass through, formed on the substrate 40. Generally, to ensure assembly reliability, particularly to fix the substrate relative to the first conductor 31 and the second conductor 32, the ozone generator further includes connecting components 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 the positions where they mate 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 can be in the form of bolts as exemplified above, and the portion extending out of the cavity 1 can be provided with external threads. Correspondingly, the connection assembly can include at least one washer and a nut. The washer can include at least one or a combination of a flat washer 451, a spring washer 452, etc.

[0176] For example, taking the first conductor 31 as an example, along its axial extension between the housing 100 and the substrate 40, the connecting assembly may include: a flat washer 451, a spring washer 452, and a nut 453. The flat washer 451 increases the contact area, thereby dispersing pressure and preventing damage to the housing 100 when the bolt is tightened. The spring washer 452 generates a certain preload, preventing the nut 453 from loosening. Along the direction of the first conductor 31, in addition to its connecting function, the connecting assembly also creates a certain gap between the substrate 40 and the housing 100, thus accommodating the mounting of electronic components on the substrate 40. Of course, the specific form of the connecting assembly is not limited to the above example; those skilled in the art can combine and arrange the connecting assembly according to the needs of actual application scenarios.

[0177] Please refer to the following: 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 further includes: a conductive layer 47 disposed 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] Specifically, the conductive layer 47 can be a conductive ring disposed at the edge of the first opening 401 and the second opening 402, and the conductive layer 47 can also cover the inner surface 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 it contacts; specifically, the size of the conductive ring is greater than or equal to the mating area of ​​the connecting component it contacts. For example, when the conductive ring contacts a nut, the outer diameter of the conductive ring is greater than or equal to the circumscribed circle diameter of the nut.

[0179] Furthermore, the specific structure of the conductive layer 47 is not limited to the examples above. It can also be adjusted according to the structure of the components of the connecting assembly that it cooperates with, such as a polygonal structure or a non-annular structure with local openings. This application does not make any specific limitations here.

[0180] Please refer to the following: Figure 1 , Figure 8 and Figure 9 In one embodiment, the conductive component extends longitudinally along a third direction Z. 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 relatively close to the electrode assembly 200, and the second substrate 42 is 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, i.e., the axial direction, of the conductive component is arranged along a third direction Z. A first substrate 41 and a second substrate 42 can be disposed at intervals along this third direction Z. The first substrate 41 is relatively close to the electrode assembly 200, and the second substrate 42 is relatively far from the electrode assembly 200. Overall, by providing the first substrate 41 and the second substrate 42, the electronic components of the control board assembly 400 can be flexibly arranged on the first substrate 41 and the second substrate 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, wherein the first substrate 41 and the second substrate 42 are connected to each other on opposite sides near the edge via a connector 43.

[0183] In this embodiment, the second substrate 42 can be a substrate relatively far from the electrode assembly 200, and the first conductor 31 and the second conductor 32 can be electrically connected to the second substrate 42 through a connecting assembly. Specifically, the connecting assembly can include at least one washer and nut provided in the above embodiment. Furthermore, the first substrate 41 and the second substrate 42 can be connected through 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 enables the electrical connection between the first substrate 41 and the second substrate 42.

[0184] Furthermore, the connecting assembly includes a top nut 454 located on the side of the second substrate 42 opposite to the first substrate 41. The first substrate 41 has a first set of openings 413 for the first conductor 31 and the second conductor 32 to pass through, and the second substrate 42 has a second set of openings 423 for the first conductor 31 and the second conductor 32 to pass through. The diameter of the second set of openings 423 is smaller than the circumscribed circle diameter of the top nut 454. A connecting assembly is provided between the first substrate 41 and the housing 100. Specifically, the composition and mating relationship of this connecting assembly can be referred to the detailed description of the embodiment with one substrate described above, which will not be repeated here.

[0185] The first aperture group 413 formed on the first substrate 41 may include two apertures spaced a certain distance apart. The diameter of the aperture group 423 is smaller than the diameter of the aperture group 413. Specifically, the diameter of the aperture group 413 is larger than the outer contour diameter of the connecting component, so that the connecting component can pass smoothly through the first aperture group 413. For example, the aperture of the first aperture group 413 may be slightly larger than the outer contour diameter of a connector of the connecting component passing through the first aperture group 413.

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

[0187] like Figure 9 As shown, in one embodiment, the second connection part is a wire harness terminal 431, which is disposed on the first substrate 41, and the second substrate 42 has a clearance groove 430 at a position directly opposite to the wire harness terminal 431.

[0188] In this embodiment, the second connecting part is mainly used for electrically connecting the control board assembly 400 to the outside. Specifically, the second connecting part can be in the form of a wire harness terminal. Of course, in this embodiment, it is not excluded that the second connecting part can be in other forms. Taking the second connecting part as a wire harness terminal as an example, it can be disposed on the first substrate 41. In order to make the ozone generator smaller, when the distance between the first substrate 41 and the second substrate 42 is set to be small, for example, when the distance between the first substrate 41 and the second substrate 42 is smaller than the installation space required for the wire harness terminal, a clearance groove 430 can be formed on the second substrate 42 so that the wire harness terminal passes through the clearance groove 430 and can be reliably installed.

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

[0190] In this embodiment, the housing 100 may have a mounting cavity 19 on the side where the conductive component is led out. Specifically, the mounting cavity 19 may be a groove formed on the housing 100. The control board assembly 400 is at least partially located within this groove. Specifically, the groove may be constructed to fit the outer contour of the control board assembly 400, for example, it may be a regular rectangular groove, thereby minimizing the space occupied by the groove and thus miniaturizing the ozone generator.

[0191] like Figure 5 As shown, furthermore, to ensure the waterproof sealing performance of the control panel assembly 400, a waterproof structure 46 is provided between the mounting cavity 19 and the control panel assembly 400. Specifically, the waterproof structure 46 may include any one or a combination of the following: a potting layer, a sealing cap, etc. For example, when the waterproof structure 46 is a potting layer, after the control panel assembly 400 is installed in the mounting cavity 19, insulating glue can be filled into the space of the mounting cavity 19 to form a potting layer covering the control panel assembly 400. By forming this potting layer, not only can the waterproof sealing performance of the control panel assembly 400 be ensured, but the control panel assembly 400 can also be reliably fixed in the mounting cavity 19. Of course, in addition to the forms of waterproof structure 46 listed above, it may also include other forms of waterproof structure 46. Those skilled in the art may make other modifications under the guidance of the technical essence of this application, but as long as the function and effect achieved are the same as or similar to this application, they should all be covered within the scope of protection of this application.

[0192] Overall, through the miniaturization design of the ozone generator in various aspects of the embodiments of this application, the size of the final ozone generator can be greatly reduced compared to existing ozone generators. Specifically, the dimensions of the housing 100 in the length, width, and height directions are within 90 mm × 40 mm × 60 mm.

[0193] In some embodiments, the control board assembly 400 may include: a plate-shaped substrate 40 and functional circuitry disposed on the substrate 40, the functional circuitry including any one or a combination of the following: a polarity reversal circuit, a current detection circuit, and a voltage regulation circuit.

[0194] In this embodiment, the control board assembly 400 may include a plate-shaped substrate 40 and functional circuitry. Specifically, the substrate 40 may be a printed circuit board (PCB). The PCB includes an insulating base plate, connecting wires, and solder pads, etc., on which electronic components are soldered 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 may include any one or a combination of a reversing circuit, a current detection circuit, and a voltage regulation circuit. Of course, the functional circuit is not limited to the examples above; the embodiments described in this application are only 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 source, 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 in use, this ozone generator utilizes a reversing circuit to prevent scaling and extend its service life. Specifically, the reversing circuit is configured such that, in its first state, the first electrode 21 is the positive electrode, the second electrode 22 is the negative electrode, and current flows from the first electrode 21 to the second electrode 22; in its second state, the first electrode 21 is the negative electrode, the second electrode 22 is the positive electrode, and current flows from the second electrode 22 to the first electrode 21.

[0198] The specific configuration of the reversing circuit can include, for example, a MOSFET, a relay, or other components with switching functions. Of course, the specific configuration of the reversing circuit is not limited to the above description. Those skilled in the art, inspired by the technical essence of this application, may make other modifications, but as long as the function and effect achieved are the same as or similar to this application, they should be covered within the scope of protection of this application. Taking a relay as an example, when its contacts are in the first connection position, connecting the first circuit, the reversing circuit is in the first state; when its contacts are in the second connection position, connecting the second circuit, the reversing circuit is in the second state.

[0199] In this embodiment, a constant voltage (e.g., 24V, 12V, 36V) is input to the ozone generator from the outside. When the electrode assembly 200 of the ozone generator is working, it can produce ozone water with an ozone concentration that meets the preset concentration requirements without the need to monitor and adjust the current. This eliminates the need for the current regulation circuit set up in the prior art to ensure the ozone water concentration.

[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 to the first surface 411. The second substrate 42 has a third surface 421 facing the second surface and a fourth surface opposite to the third surface 421. The reverse electrode circuit is disposed 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, which includes a first substrate 41 and a 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 the top nut 454 is installed, it may come into contact with 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 inverted electrode circuit, the inverted electrode circuit can be disposed on at least one of the first surface 411, the second surface, and the third surface 421, while avoiding the fourth surface. Furthermore, in an embodiment where the second connection portion is disposed on the first substrate 41, the inverted electrode circuit can be disposed 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 for detecting the operating current of the electrode assembly 200.

[0204] In this embodiment, by setting a current detection circuit to detect the operating current of the electrode assembly 200, the current can be used as a feedback signal to determine the current water quality, and then the duration / frequency of the polarity reversal can be flexibly adjusted based on the current water quality.

[0205] For different water qualities, the worse the water quality, the more calcium and magnesium ions there are, making it easier for scale to form quickly on the electrode surface. Under the same voltage, the current detection circuit can detect a larger current. In this case, to prevent scale formation on the electrode surface, the reversal time can be shortened. Conversely, the better the water quality, the fewer calcium and magnesium ions there are, making it less likely for scale to form quickly on the electrode surface. Under the same voltage, the current detection circuit can detect a smaller current. In this case, to prevent scale formation 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. The control board assembly 400 includes a substrate 40. The substrate 40 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 to the first surface 411. The second substrate 42 has a third surface 421 facing the second surface and a fourth surface opposite to the third surface 421. The current detection circuit is disposed on the third surface 421, and the reverse polarity circuit is disposed on the first surface 411 and / or the second surface.

[0207] In this embodiment, the reason why the current detection circuit is not located on the fourth surface can be referred to the reason why the reverse polarity circuit avoids the fourth surface as described above. Furthermore, the current detection circuit is a further functional optimization compared to the reverse polarity circuit. Therefore, the more fundamental and important reverse polarity circuit can be located on the first surface 411 and / or the second surface. This ensures that even if the connection components (e.g., pin headers) between the second substrate 42 and the first substrate 41 subsequently malfunction, the normal operation of the reverse polarity circuit will not be affected.

[0208] In one embodiment, the second connection is electrically connected to an external preset controller, which 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 a constant external voltage (e.g., 24V, 12V, 36V), its electrode assembly 200 can produce ozone water with an ozone concentration meeting a preset requirement during electrolysis, without the need for current monitoring and adjustment. This constant voltage (i.e., the preset voltage) can be provided directly by an external controller, or a voltage signal can be provided by an external controller, and the voltage regulation circuit on the control board assembly 400 can adjust the externally input voltage based on this voltage signal to achieve the preset voltage.

[0210] In one embodiment, the functional circuit may further include a voltage regulating circuit. After the second connection part is electrically connected to the preset controller, the preset controller can 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 that can adjust the voltage input by the preset controller to reach a predetermined voltage, thereby applying it to the electrode assembly 200.

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

[0213] This application also provides a water system comprising the ozone generator described in the above embodiments. By incorporating the ozone generator, this water system achieves the technical effects described in the ozone generator embodiments. For details, please refer to the specific descriptions of the above embodiments; further elaboration is not required here.

[0214] In some embodiments, the water system may further include: a main unit, the main unit being equipped with a controller, the controller being connectable to the second connection part; and a water passage for water flow, through which at least a portion of the water can pass through the ozone generator.

[0215] In this embodiment, the water system can be any form that requires the use of ozone water. Specifically, the water system may 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 examples above.

[0216] The water system is equipped with a main unit, the specific form of which can vary depending on the form of the main system, and this application does not impose a specific limitation here. The main unit is equipped with a controller, which is connected to the second connection part and can serve as the preset controller mentioned in the above 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 passage for water flow. The ozone generator can be connected to this water passage. When the water in the water flow passes through the ozone generator and the start-up conditions for ozone preparation are met, the ozone generator can be started to prepare ozone water.

[0218] Furthermore, the water system may include a pressure 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 the specific description in the above ozone generator implementation, and will not be repeated here. Wherein, when the controller is equipped with a voltage regulating circuit, the control board assembly 400 no longer needs to have its own voltage regulating circuit and can directly utilize the voltage regulating circuit in the controller to achieve voltage adjustment, thereby simplifying the control board assembly 400 and reducing the size and cost of the ozone generator.

[0220] In a specific scenario, such as when the ozone generator is used in a water purifier, if the water flowing into the ozone generator is purified water, the calcium and magnesium ions that easily cause scale formation have already been filtered out by the filter element in the water purifier. Therefore, when the ozone generator is powered on, scale is not easily formed, and the reverse polarity circuit is no longer needed. In this case, only a voltage regulation circuit needs to be set in the controller or control board assembly 400. The electrode serving as the anode in the ozone generator can be coated with the coating material described in the above embodiments (e.g., any one of boron-doped diamond electrode, tin dioxide electrode, lead dioxide electrode, and platinum electrode), while the electrode serving as the cathode does not need to be coated, and its material can be low-cost stainless steel, titanium, etc.

[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 and switch the current flow direction of the electrodes in the electrode assembly 200 in a predetermined manner. The reversing circuit can be referred to the specific description of the ozone generator embodiment described above, and will not be repeated here.

[0222] In this embodiment, the structure and function of the inverted electrode circuit itself can be referred to the specific description of the ozone generator embodiment described above. The difference from the above embodiment is that the inverted electrode circuit is located in the controller. When the inverted electrode circuit is located in the controller, it is equivalent to eliminating the need for the inverted electrode circuit in the ozone generator. This simplifies the control board assembly 400 and reduces 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 reversal duration / frequency based on the operating current of the electrode assembly 200 detected by the current detection circuit.

[0224] In this embodiment, the water system may also include a current detection circuit. The function of the current detection circuit itself can be referred to the specific description of the ozone generator embodiment described above. When the current detection circuit is installed in the water system, it can be omitted from the ozone generator that originally has a current detection circuit. This simplifies the control board assembly 400 and reduces the size and cost of the ozone generator.

[0225] The reversal time of the electrode assembly 200 can be adjusted based on the result of the current detection circuit. The specific control logic for adjusting the reversal time 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 inverted electrode circuit is between 0.6A and 3A. Within this operating current range, the electrode assembly 200 can stably and reliably produce ozone water with a concentration that meets the usage requirements.

[0227] In one embodiment, the water system may further include: a detection element electrically connected to the controller, the detection element including a first detection element for acquiring user water usage signals, and the controller being configured to: when the first detection element detects user water usage signals, control power supply to provide a predetermined voltage or voltage signal to the control board assembly 400.

[0228] To ensure user safety, the ozone generator can be activated only after the user's water usage signal is received. This prevents damage and safety issues such as short circuits or combustion caused by the electrodes operating without water.

[0229] Specifically, the water system itself can be equipped with a detection device, which may include a first detection device for acquiring the user's water usage signal. The ozone generator can use the first detection device to determine whether it can be started. This is equivalent to eliminating the flow detection device and the corresponding functional circuit inside the ozone generator, thereby reducing the size of the housing 100 and simplifying the control board assembly 400, and further reducing the size and cost of the ozone generator.

[0230] The first detection element may include any one or a combination of the following: a flow detection element, a flow switch, a control valve installed in or connected to the water circuit, and an operating unit (starting unit). Of course, the specific form of the first detection element is not limited to the examples above. Generally, water systems commonly use flow detection elements to accurately obtain the current flow rate through the ozone generator. Based on the controller's control logic, it can be determined whether the flow rate through the ozone generator reaches the safe flow rate for starting the ozone generator. If it does, the ozone generator can be started.

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

[0232] In this embodiment, the detection element may further include a second detection element, which 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 according to the operating conditions of the ozone generator. The predetermined voltage ranges from 12V to 36V.

[0233] For example, the flow rate and temperature of the water flowing through an ozone generator vary depending on the specific scenario, and these factors significantly affect the concentration of ozone water actually produced. To balance these flow rate and temperature parameters, the ozone generator can utilize flow rate and / or temperature sensors within the water system to precisely match the predetermined voltage applied to the electrode assembly 200. Since the ozone generator itself does not add any components or circuitry, its size and cost remain unchanged.

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

[0235] For ozone generators, the specific values ​​of the water flowing through them vary depending on the scenario, and water quality has a certain impact on the ozone concentration and reversal time produced by the ozone generator. To take into account these water quality parameters, the ozone generator can utilize the water quality detection device in the water system to precisely match the predetermined voltage applied to the electrode assembly 200 and adjust the reversal time. Since the ozone generator itself does not add any components or circuits, its size and cost will not increase additionally.

[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 a current predetermined voltage based on the current TDS value representing the current water quality obtained from the water quality sensor, the initial TDS value, and the initial predetermined voltage. For example, a correction coefficient can be determined between the obtained current TDS value and the initial TDS value, and this correction coefficient can be used to correct the initial predetermined voltage to obtain the current predetermined voltage.

[0237] In one embodiment, the second detection element includes a flow rate detection element and a temperature detection element. The controller stores a first correspondence between 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 rate detection element, the current temperature detected by the temperature detection element and the first correspondence.

[0238] In this embodiment, the second detection element may include a flow rate detection element, a temperature detection element, and a water quality detection element. When determining the predetermined voltage, the controller can first determine an initial predetermined voltage based on the current flow rate detected by the flow rate detection element and the current temperature detected by the temperature detection element, according to a first correspondence. Further, it determines a correction coefficient by combining the current TDS water quality and the initial TDS water quality in the controller, and uses this correction coefficient to correct the initial predetermined voltage, thereby obtaining the current predetermined voltage. The specific form of the first correspondence may be a table, a function, etc., and this application does not impose a unique limitation on it.

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

[0240] The controller stores a second correspondence between flow rate, temperature, electrode working time, and predetermined voltage under different water quality conditions; the controller is configured to: determine the predetermined voltage under the conditions of current flow rate, current temperature, and current electrode working time based on the water quality detected by the water quality detector, the current flow rate detected by the flow rate detector, the current temperature detected by the temperature detector, the electrode working time 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 correspondence. 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 for electrodes with different working times, which meets the usage needs in the scenario where the working time of the electrode 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 equipped with a corresponding housing, and the position of the ozone generator relative to this housing is not limited. For example, the ozone generator can be pre-installed inside the housing, installed on the housing, or installed outside the housing. For instance, the ozone generator can be an optional feature of the water system, flexibly selected according to different user needs. When a user requires ozone water functionality, the ozone generator can be installed in the water system.

[0244] Furthermore, the outer casing is provided with a water inlet and a water outlet. The inlet 11 can be connected to the water inlet, and 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 located downstream of the water outlet, and the inlet 11 is connected to the water outlet.

[0245] When this ozone generator is used in a water system, its installation location can vary depending on the function of the water system requiring ozone water, and this application does not impose specific limitations here. For example, for a water heater, it can be installed at the outlet of the casing or in the pipe upstream of the outlet. When the hot water produced by the water heater meets the user's preset temperature, it flows through the ozone generator, thereby producing hot ozone water. For example, for a dishwasher, the ozone generator can be installed at the inlet of the water heater or in the pipe upstream of the inlet. Water supplied from an external water source flows through the ozone generator and produces ozone water for the dishwasher to use for cleaning.

[0246] It should be noted that in the description of this application, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more.
