Description

Technical Field

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

[0002] Ozone is composed of three oxygen atoms and is a powerful natural oxidant and bactericide. The ozone layer in the atmosphere can absorb harmful ultraviolet rays from sunlight and protect surface organisms. High-purity ozone produced by the ozone industry replaces chlorine disinfection and is widely used in tap water treatment, packaged water, water for medical processes, and water for food processes. Ozone has the functions of sterilization, oxidation, decolorization, deodorization, and advanced oxidation in water. When ozone decomposes in water, the hydroxyl radicals produced have strong oxidizing power and can quickly decompose iron, manganese, odor, odor, bacteria, viruses, etc. in water, and can also eliminate chlorine or trihalomethanes in tap water.

[0003] At present, a typical method of producing ozone is electrolysis. When ozone water is prepared by electrolysis, an ozone generator is usually provided. The basic structure of the ozone generator includes an anode, a cathode and a membrane sandwiched in the middle for proton exchange. When water flows into the ozone generator, the oxygen in the water molecules can be electrolyzed and combined into ozone molecules. The ozone produced in this way is of high purity and high content, which can meet the needs of sterilization, detoxification, preservation, deodorization, bleaching, etc.

[0066] The utility model provides an ozone generating device and a water supply device, which can effectively improve the efficiency of the ozone generating device in generating ozone and optimize the performance of the ozone generating device.

[0067] Please refer to Figures 1 to 8 In an embodiment of the specification of the present application, an ozone generating device 100 is provided, and the ozone generating device 100 may include: a shell 10, the shell 10 is provided with a water inlet 101, a water outlet 102 and a receiving cavity connecting the water inlet 101 and the water outlet 102; an electrode assembly, the electrode assembly includes: a main electrode 11, an auxiliary electrode 12, and a proton exchange membrane 13 located between the main electrode 11 and the auxiliary electrode 12; the electrode assembly is arranged in the receiving cavity; the main electrode 11 is in the form of a plate with a predetermined thickness, the main electrode 11 has a first surface 111 and a second surface 112 along the thickness direction, and the main electrode 11 is provided with pores 113 penetrating the first surface 111 and the second surface 112; the proton exchange membrane 13 is a complete sheet structure, and the main electrode 11 is in close contact with the proton exchange membrane 13.

[0068] In the embodiment of the present application, the ozone generating device 100 may mainly include: a shell 10 , and an electrode assembly disposed in the shell 10 , and the electrode assembly mainly includes: a main electrode 11 , an auxiliary electrode 12 and a proton exchange membrane 13 .

[0069] The present application will be described in detail below with reference to specific drawings and implementation methods.

[0070] Please refer to Figure 2 , Figure 4 and Figure 7 The housing 10 may include a detachably connected base 110 and an end cap 120. A receiving cavity is formed in the housing 10 by the base 110 and the end cap 120. The main electrode 11, the proton exchange membrane 13 and the auxiliary electrode 12 are located in the receiving cavity. The detachable connection between the base 110 and the end cap 120 may be threaded connection, such as screw 18 connection. Figure 7As shown, when the base 110 and the end cover 120 are connected by screws 18, screw holes can be evenly arranged around the end cover 120 and the base 110, and the screw holes and the screws 18 are used for installation, so as to realize the connection between the base 110 and the end cover 120. The number of the screws 18 can be different according to the specific structure of the end cover 120 and / or the base 110. For example, when the overall outer contour of the end cover 120 is rectangular or quasi-rectangular, the number of the screws 18 can be four, and the four screws 18 are distributed on the four corners of the end cover 120.

[0071] Of course, the detachable connection between the base 110 and the end cover 120 also includes a snap connection or other forms, and is not limited to the above description. Technical personnel 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 covered within the scope of protection of this application.

[0072] The housing 10 is provided with a water inlet 101 and a water outlet 102. The water inlet 101 and the water outlet 102 can be communicated with the accommodating cavity respectively. The water inlet 101 is provided at any one of the following positions: on the base 110, on the end cover 120, or on the base 110 and the end cover 120; the water outlet 102 is provided at any one of the following positions: on the base 110, on the end cover 120, or on the base 110 and the end cover 120.

[0073] Specifically, the water inlet 101 can be set on the base 110, and it can be an opening formed on the base 110; or, the water inlet 101 can be formed by assembling the base 110 and the end cover 120, for example, the water inlet 101 can be a notch formed on the base 110, and / or, the water inlet 101 can be a notch formed on the end cover 120; or, the water inlet 101 can be an opening formed on the end cover 120.

[0074] Specifically, the water outlet 102 can be set on the base 110, and it can be an opening formed on the base 110; or, the water outlet 102 can be formed by assembling the base 110 and the end cover 120, for example, the water outlet 102 can be a notch formed on the base 110, and / or, the water outlet 102 can be a notch formed on the end cover 120; or, the water outlet 102 can be an opening formed on the end cover 120.

[0075] In this embodiment, the main electrode 11 may be in the form of a plate with a predetermined thickness, and has a first surface 111 and a second surface 112 along the thickness direction of the main electrode 11, wherein the second surface 112 is a surface that is in contact with the proton exchange membrane 13. The first surface 111 is a surface that is relatively far away from the proton exchange membrane 13.

[0076] The thickness of the main electrode 11 may vary depending on the material, manufacturing process, etc., and the present application does not make any specific numerical limitation. A through hole 113 is provided on the main electrode 11 along the thickness direction. The proton exchange membrane 13 is a complete sheet, and no hole structure is provided on the proton exchange membrane 13, so that the main electrode 11 and the auxiliary electrode 12 are effectively separated.

[0077] When the main electrode 11 is an anode, the pore 113 can be used to expand the circumference of the three-phase interface between the main electrode 11, water and the proton exchange membrane 13, thereby improving the efficiency of the electrolysis reaction; in addition, when the pore 113 is provided on the main electrode 11, it is beneficial for the ozone water generated at the interface between the main electrode 11 and the proton exchange membrane 13 to be efficiently discharged to the side away from the proton exchange membrane 13.

[0078] The shape, structure, size and distribution position of the pores 113 may vary according to the flushing direction of the water flow, the structure of the main electrode 11 and the performance requirements of the ozone generating device 100. Figure 8 As shown, the main electrode 11 may be a rectangular structure or a quasi-rectangular structure, having a relative length direction and a width direction, the size of the main electrode 11 in the length direction is greater than the size in the width direction, the pores 113 may be strip holes extending along the width direction, the number of the strip holes is multiple, and the multiple strip holes are arranged at intervals along the length direction. Specifically, the strip holes may be rectangular holes with equal widths, or waist-shaped holes with unequal widths.

[0079] When water enters the containing cavity from the water inlet 101, it will flow through the main electrode 11. Since the overall direction of the water flow forms a certain angle with the direction in which the pore 113 extends, for example, approximately vertical, the pore 113 can be directly flushed, which is more conducive to carrying away the generated ozone water and outputting it to the user's water terminal.

[0080] For the main electrode 11, a precious metal oxide layer (coating) is deposited on the second surface 112 facing the proton exchange membrane 13, and the precious metal oxide layer will be gradually consumed during use. In theory, the surface area of ​​the precious metal oxide layer is proportional to its service life.

[0081] At the same time, for the main electrode 11 provided with the pore 113, the perimeter of the pore 113 is conducive to increasing the perimeter of the three-phase interface when the main electrode 11 is used as an anode, thereby facilitating the improvement of the efficiency of the electrolytic reaction. In theory, the longer the perimeter of the three-phase interface increased by providing the pore 113, the better the effect of improving the efficiency of the electrolytic reaction.

[0082] Taking into account the service life of the main electrode 11 and the efficiency of the main electrode 11 as an anode for electrolysis reaction, the ratio of the effective area of ​​the main electrode 11 to its surface area can be between 15% and 95%.

[0083] In some embodiments, the auxiliary electrode 12 is in the form of a plate with a predetermined thickness. Specifically, the auxiliary electrode 12 may be in the form of a complete plate, and no hole structure is provided on the auxiliary electrode 12, and the auxiliary electrode 12 is in the form of a complete plate. For a complete sheet or plate-shaped structure, the manufacturing process is simple and the manufacturing cost is low; since no additional holes are required, the process can be reduced and the defective rate can also be reduced.

[0084] For the main electrode 11 in a plate-like structure and the proton exchange membrane 13 in a sheet-like structure, the second surface 112 of the main electrode 11 is in contact with one surface of the proton exchange membrane 13. Such assembly can ensure direct contact between the main electrode 11 and the proton exchange membrane 13.

[0085] When the main electrode 11 is the anode, ozone is generated at the three-phase interface of water, the proton exchange membrane 13 and the main electrode 11. After the main electrode 11 is in direct contact with the proton exchange membrane 13, the migration path of the conductive ions is shortened, the electrolysis reaction can be accelerated, and ozone is generated quickly, thereby effectively improving the efficiency of the ozone generating device 100 in generating ozone.

[0086] The second surface 112 of the main electrode 11 is fitted with one of the surfaces of the proton exchange membrane 13. Such assembly can ensure that the main electrode 11 and the proton exchange membrane 13 are in surface contact. When the main electrode 11 and the proton exchange membrane 13 are fitted to form surface contact, the three-phase interface of the main electrode 11 (coating), water and the proton exchange membrane 13 is formed at the periphery of the main electrode 11, the proton exchange membrane 13 in contact with water, and the periphery where the pores 113 are opened. On the whole, the electrolysis reaction starts at the outermost side of the pressing, and as the reaction time increases, the coating gradually dissolves slowly from the outside to the inside, which is conducive to extending the service life of the main electrode 11.

[0087] In addition, for the main electrode 11 provided with the pores 113, during use, the circumference of the outer periphery of the entire main electrode 11 coating gradually decreases, while the circumference at the pores 113 gradually increases. The increase in the circumference of the pores 113 can compensate for the decrease in the outer circumference of the entire main electrode 11, which is beneficial to ensure that the main electrode 11 always has a high electrolysis reaction efficiency when used as an anode.

[0088] In addition, the auxiliary electrode 12 can be attached to another surface of the proton exchange membrane 13 to form a compact electrode assembly, which is convenient for positioning and installing the entire electrode assembly later.

[0089] When the main electrode 11 is used as the positive electrode and the auxiliary electrode 12 is used as the negative electrode, the water flowing in from the water inlet 101 can generate ozone to form ozone water when flowing through the main electrode 11 to be outputted externally.

[0090] Specifically, the main electrode 11 may include any one of a boron-doped diamond electrode, a tin dioxide electrode, a lead dioxide electrode, and a platinum electrode.

[0091] The material of the main electrode 11 can be selected from precious metal oxides. In addition to the materials of the boron-doped diamond electrode, tin dioxide electrode, lead dioxide electrode, and platinum electrode listed above, the present application does not exclude the use of other precious metal oxide materials for the main electrode 11. On the whole, the material of the main electrode 11 can be selected to have a long service life and relatively low cost, provided that the reliability and safety requirements are met.

[0092] When the main electrode 11 is used as a negative electrode and the auxiliary electrode 12 is used as a positive electrode, the water flowing in from the water inlet 101 does not generate ozone when flowing through the auxiliary electrode 12. The concentration of ozone water output by the ozone generating device 100 can be adaptively adjusted by using the auxiliary electrode 12 for polarity reversal to output ozone water that meets the needs of users. In addition, the main electrode 11 is used as the auxiliary electrode 12 for polarity reversal, and the corresponding material cost is relatively low.

[0093] Specifically, the auxiliary electrode 12 may include any one of a stainless steel electrode, a titanium and titanium alloy electrode, a zirconium and zirconium alloy electrode, a carbon electrode, and an oxide coating electrode.

[0094] The auxiliary electrode 12 may be made of a metal electrode, a non-metal electrode or an oxide-coated electrode that is different from the material of the main electrode 11. Specifically, in addition to the above-mentioned stainless steel electrode, titanium and titanium alloy electrode, zirconium and zirconium alloy electrode, carbon electrode, oxide-coated electrode and other materials, the present application does not exclude the auxiliary electrode 12 from using other materials.

[0095] In some embodiments, the main electrode 11 , the proton exchange membrane 13 , and the auxiliary electrode 12 are stacked, and along the projection of the stacking direction, the projection of the proton exchange membrane 13 completely covers the projection of the main electrode 11 .

[0096] In this embodiment, the plate-shaped main electrode 11, the sheet-shaped proton exchange membrane 13, and the plate-shaped auxiliary electrode 12 can be stacked in sequence along the thickness direction, wherein when the proton exchange membrane 13 is projected onto the main electrode 11 along the stacking direction, the proton exchange membrane 13 can completely cover the main electrode 11. Such an arrangement can ensure that the main electrode 11 and the proton exchange membrane 13 have a maximum reaction area, that is, the entire surface of the main electrode can participate in the reaction; at the same time, the proton exchange membrane 13 is used as an isolation member between the main electrode 11 and the auxiliary electrode 12 to reliably isolate the main electrode 11 and the auxiliary electrode 12 to prevent the main electrode 11 and the auxiliary electrode 12 from being connected after subsequent scaling, thereby preventing a short circuit and affecting the service life of the ozone generating device 100.

[0097] Please refer to Figure 5 and Figure 6 In some embodiments, there is a first gap between the main electrode 11 and the shell 10, and there is a second gap between the auxiliary electrode 12 and the shell 10; the water inlet 101 is connected to the first gap and the second gap respectively; the water outlet 102 is connected to the first gap and the second gap respectively.

[0098] In one embodiment, there is a first gap between the main electrode 11 and the shell 10, and there is a second gap between the auxiliary electrode 12 and the shell 10; the water inlet 101 is connected to the first gap and the second gap respectively; the water outlet 102 is connected to the first gap and the second gap respectively. When the main electrode 11 and the auxiliary electrode 12 are connected to the water inlet 101 and the water outlet 102 of the shell 10 through the gap, it can ensure that the main electrode 11 and the auxiliary electrode 12 are fully in contact with the water flowing through the electrode assembly, so that the electrolysis reaction process is stable, and at the same time, the reaction of the auxiliary electrode 12 is not restricted.

[0099] In the embodiment of the present application, when the main electrode 11 is used as the positive electrode and the auxiliary electrode 12 is used as the negative electrode, the water flowing in from the water inlet 101 can generate ozone to form ozone water for external output when flowing through the main electrode 11. When the main electrode 11 is used as the negative electrode and the auxiliary electrode 12 is used as the positive electrode, the water flowing in from the water inlet 101 does not generate ozone when flowing through the auxiliary electrode 12. In this way, when the main electrode 11 and the auxiliary electrode 12 are alternately used as the positive electrode, the ozone generating device 100 can output ozone water externally only when the main electrode 11 is used as the positive electrode. When the ozone water segment that outputs and the ozone water segment that does not output are combined, it is beneficial to reasonably control the concentration of the ozone water output to the outside, and greatly reduce the potential safety hazards caused by excessive concentration of ozone water during long-term use (for example, during bathing); at the same time, when the auxiliary electrode 12 is used as the positive electrode, the ozone generating device 100 does not generate ozone. At this time, a lower-cost material can be selected as the auxiliary electrode 12, which can reduce the cost of the machine and extend the service life of the machine, thereby better meeting the needs of users.

[0100] In the embodiment of the present application, when the main electrode 11 serves as the positive electrode and the auxiliary electrode 12 serves as the negative electrode, ozone can be generated to form ozone water for external output. The surface area of ​​the main electrode 11 can be optimized. For example, relative to the embodiment in which both electrodes can serve as positive electrodes to produce ozone water, the surface area of ​​the main electrode 11 can be set to be larger than the scenario in which any one electrode can serve as the positive electrode to produce ozone water. In this way, the current density on the main electrode 11 can be reduced, the loss of the main electrode 11 can be effectively slowed down, and the service life of the main electrode 11 can be extended more effectively and reliably.

[0101] In addition, when the auxiliary electrode 12 is used as the positive electrode, the ozone generating device 100 is in a reverse polarity state, and an acidic environment is generated during the reverse polarity, which can neutralize the alkaline environment of the main electrode 11 as the positive electrode, thereby slowing down the generation of scale.

[0102] In some embodiments, the main electrode 11 and the auxiliary electrode 12 are connected to a control circuit, and the control circuit includes a switching circuit for switching the positive and negative poles of the main electrode 11 and the auxiliary electrode 12, and the switching circuit is configured as follows: when the switching circuit is in a first state, the main electrode 11 is a positive pole and the auxiliary electrode 12 is a negative pole; the water flowing in from the water inlet 101 can generate ozone to form ozone water when flowing through the main electrode 11 and output from the water outlet 102; when the switching circuit is in a second state, the main electrode 11 is a negative pole, and the auxiliary electrode 12 is a positive pole, and the water flowing in from the water inlet 101 does not generate ozone when flowing through the auxiliary electrode 12.

[0103] In this embodiment, the main electrode 11 and the auxiliary electrode 12 are connected to a control circuit, wherein the control circuit is connected to the main electrode 11 and the auxiliary electrode 12 respectively, so that the voltage / current applied by the power supply module can be applied to the main electrode 11 and the auxiliary electrode 12 .

[0104] Specifically, the setting position of the control circuit can include a variety of different ways, for example, the control circuit can be set on the ozone generating device 100. Alternatively, the control circuit can be set separately from the ozone generating device 100, for example, it can be set in the controller of the specific device used by the ozone generating device 100. Alternatively, the control circuit can include multiple functional modules, for example, a first functional module, a second functional module, or more functional modules, and the present application takes two parts as an example for illustration. Among them, the first functional module can be set on the ozone generating device 100, and the second functional module can be set separately from the ozone generating device 100, for example, it can be set in the controller of the specific device used by the ozone generating device 100.

[0105] Among them, a functional module in the control circuit can be used to realize the switching of the positive and negative poles of the main electrode 11 and the auxiliary electrode 12.

[0106] In one embodiment, the control circuit may include a switching circuit for switching the positive and negative poles of the main electrode 11 and the auxiliary electrode 12, and the switching circuit is configured as follows: when the switching circuit is in a first state, the main electrode 11 is a positive pole and the auxiliary electrode 12 is a negative pole; when the switching circuit is in a second state, the main electrode 11 is a negative pole and the auxiliary electrode 12 is a positive pole.

[0107] In this embodiment, the switching circuit may include two states, a first state and a second state, and when the switching circuit is in different states, the polarities applied to the main electrode 11 and the auxiliary electrode 12 are opposite. When the switching circuit is in the first state, the main electrode 11 can be connected to the positive electrode of the power supply module, and the auxiliary electrode 12 can be connected to the negative electrode of the power supply module. At this time, the main electrode 11 is the positive electrode, and the auxiliary electrode 12 is the negative electrode; when the switching circuit is in the second state, the main electrode 11 can be connected to the negative electrode of the power supply module, and the auxiliary electrode 12 can be connected to the positive electrode of the power supply module. At this time, the main electrode 11 is the negative electrode, and the auxiliary electrode 12 is the positive electrode.

[0108] Among them, the specific configuration of the switching circuit may include: MOS tube, single-pole double-throw switch as an example, or it may also be in the form of other components with switching functions. Of course, the specific configuration of the switching circuit is not limited to the above description. The technical personnel in the relevant field may make other changes under the inspiration of 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 protection scope of this application. Taking the single-pole double-throw switch as an example, when its knife is in the first connection position and connected to the first circuit, the switching circuit is in the first state; when its knife is in the second connection position and connected to the second circuit, the switching circuit is in the second state.

[0109] Furthermore, the control circuit includes a time control module, and the time control module is used to control the working duration of the first state and the second state.

[0110] In this embodiment, a functional module of the control circuit is used to control the working time of the first state and the second state, that is, it can control the time when the main electrode 11 is used as an anode and the auxiliary electrode 12 is used as a cathode to produce ozone water, and the time when the main electrode 11 is used as a cathode and the auxiliary electrode 12 is used as an anode and does not produce ozone water. By controlling the working time of the first state and the second state, the time when ozone water is produced and the time when ozone water is not produced can be reasonably controlled, so that the concentration of ozone water output to the user terminal can be adjusted to be highly adapted to the user's usage needs and improve the user's usage experience.

[0111] like Figure 7 As shown, in some embodiments, the ozone generating device 100 may further include a first conductor 14 and a second conductor 15, wherein the first conductor 14 is connected to the main electrode 11, and the second conductor 15 is connected to the auxiliary electrode 12, and a power supply module can supply power to the ozone generating device 100 through the first conductor 14 and the second conductor 15.

[0112] In this embodiment, in order to apply the voltage / current provided by the external power supply module to the main electrode 11 and the auxiliary electrode 12, the ozone generating device 100 is further provided with a first conductor 14 and a second conductor 15. The first conductor 14 can be used to electrically connect the power supply module with the main electrode 11, so that the power supply module can supply power to the main electrode 11; the second conductor 15 can be used to electrically connect the power supply module with the auxiliary electrode 12, so that the power supply module can supply power to the auxiliary electrode 12. The power supply module is connected to an external power source and is connected to the main electrode 11 and the auxiliary electrode 12.

[0113] The first conductor 14 may include: a conductive frame 142 and a first conductive column 141. The conductive frame 142 may be a hollow frame structure, and its outer contour may be adapted to the outer contour of the main electrode 11. For example, when the outer contour of the main electrode 11 is a rectangle, the conductive frame 142 may be a rectangular frame. Of course, the structure of the main electrode 11 and the specific structure of the conductive frame 142 may also be other shapes, and the present application does not specifically limit their structures. In the embodiments and drawings of the present application, the conductive frame 142 is mainly illustrated as a rectangular frame when the outer contour of the main electrode 11 is a rectangle.

[0114] When the conductive frame 142 is a rectangular frame, it has opposite long sides and short sides, wherein at least one of the long sides and short sides of the rectangular frame is in contact with the main electrode 11, so that the voltage / current provided by the power supply module can be applied to the main electrode 11. A connecting portion is provided on one side of the conductive frame 142, and the connecting portion is used to connect the first conductive column 141. One end of the first conductive column 141 is connected to the connecting portion, and the other end extends out of the housing 10 to be connected to the power supply module. The external power supply module can apply voltage / current to the main electrode 11 through the first conductive column 141 and the conductive frame 142.

[0115] For the main electrode 11 and the conductive frame 142 of a rectangular structure, in order to extend the contact time between the water flow and the electrode and ensure that the electrolysis reaction is fully carried out, the water inlet 101 and the water outlet 102 are relatively arranged along the long side direction of the main electrode 11 and the conductive frame 142. At this time, in order to prevent the first conductive column 141 from interfering with structures such as the water inlet 101 and the water outlet 102, the first conductive column 141 can be arranged on the long side of the conductive frame 142, that is, the connecting portion can be a partial protrusion formed on the long side of the conductive frame 142.

[0116] In this embodiment, the second conductor 15 can be provided separately from the auxiliary electrode 12. When the second conductor 15 is provided separately from the auxiliary electrode 12, the specific composition and connection relationship of the second conductor 15 can refer to the specific description of the first conductor 14, and the present application will not repeat them here.

[0117] like Figure 7 As shown, in a specific embodiment, considering that the auxiliary electrode 12 in the embodiment of the present application is an auxiliary electrode 12 for polarity reversal, the second conductor 15 can be integrally formed with the auxiliary electrode 12 .

[0118] In this embodiment, the second conductor 15 and the auxiliary electrode 12 are integrally formed. Such a configuration can simplify the structure of the ozone generating device 100 and reduce the volume of the ozone generating device 100. Compared with the embodiment in which the second conductor 15 and the auxiliary electrode 12 are separately configured, the cost of the ozone generating device 100 can be further reduced and the reliability of the ozone generating device 100 during use can be improved.

[0119] Please refer to Figure 3 and Figure 7 A connecting portion is provided on one side of the auxiliary electrode 12, and the connecting portion is used to connect the second conductive column 151. One end of the second conductive column 151 is connected to the connecting portion, and the other end extends out of the housing 10 to be connected to the power supply module. The external power supply module can apply voltage / current to the auxiliary electrode 12 through the second conductive column 151.

[0120] In one embodiment, the main electrode 11 is a boron-doped diamond electrode, and the main electrode 11 is separately bonded to the first conductor 14 to make the main electrode 11 and the first conductor 14 electrically conductive, and the main electrode 11 and the first conductor 14 are not mechanically connected.

[0121] In this embodiment, the main electrode 11 can be a silicon-based boron-doped diamond electrode or a boron-doped diamond electrode with other base materials as the main body and formed by depositing a coating on its surface. For the boron-doped diamond electrode, when it is used as a cathode, scaling can be avoided by reversing the polarity, thereby extending its service life.

[0122] For the boron-doped diamond electrode, it is impossible to achieve fixed connection through traditional mechanical connection methods such as welding and threaded connection. In order to ensure that the first conductor 14 can be reliably connected to the main electrode 11 without mechanical connection, so that the voltage / current provided by the external power supply module is applied to the main electrode 11, the first conductor 14 is separately provided with the main electrode 11 and the first conductor 14 is directly attached to the main electrode 11, so as to achieve electrical conduction between the main electrode 11 and the first conductor 14.

[0123] In one embodiment, the main electrode 11 is a boron-doped diamond electrode, and a buffer module 161 is disposed between the main electrode 11 and the housing 10 . The buffer module 161 is configured to have an adjustable compression amount.

[0124] In this embodiment, the main electrode 11 can be a silicon-based boron-doped diamond electrode or a boron-doped diamond electrode with other base materials as the main body and formed by depositing a coating on its surface. For the boron-doped diamond electrode, when it is used as a cathode, scaling can be avoided by reversing the polarity, thereby extending its service life.

[0125] Taking the silicon-based boron-doped diamond electrode as an example, for the silicon-based boron-doped diamond electrode, since the main component of its material is a silicon-based material, which is a brittle material, it is easy to break under the action of external force. In order to provide limited protection to the main electrode 11 and effectively position the main electrode 11, and to ensure that the main electrode 11 and the proton exchange membrane 13 are always in reliable ground contact, a buffer module 161 can be set between the main electrode 11 and the shell 10. For example, the buffer module 161 can be set between the main electrode 11 and the end cover 120. Of course, when other brittle matrix materials are used as the main body to form a boron-doped diamond electrode, a buffer module 161 is also required to achieve the same or similar technical effects.

[0126] The buffer module 161 can be a structure with adjustable compression. In the process of assembling the end cap 120 and the base 110, the compression amount is adaptively adjusted by the buffer module 161 to generate corresponding deformation, which can ensure the reliable fit between the first conductor 14 and the main electrode 11. The excessive force generated during the production and assembly process can also be released slowly through the deformation of the buffer module 161 itself to prevent it from being transmitted to the electrode and crushing the electrode. In a specific scenario, during the assembly process, the fastening force formed between the end cap 120 and the base 110 is uneven. For example, when the end cap 120 and the base 110 are connected by screws 18, the number of turns of the screws 18 may be different, and the pre-tightening force generated at this time is different. Since the buffer module 161 is provided, the destructive effect of the pre-tightening force on the main electrode 11 can be weakened.

[0127] In addition, in some embodiments, the ozone generating device 100 may further include a mounting frame 17. The main electrode 11 and the auxiliary electrode 12 are respectively limited on both sides of the mounting frame 17; the buffer module 161 and the buffer member 162 are respectively fixed on both sides of the mounting frame 17 and respectively press and limit the main electrode 11 and the auxiliary electrode 12. The mounting frame 17 may be a rectangular frame structure, and there are limiting columns on both sides of the rectangular frame structure. The main electrode 11 and the auxiliary electrode 12 are positioned under the limiting action of multiple limiting columns and supported by the mounting frame 17. The mounting frame 17 is an insulating member, for example, its material may be plastic.

[0128] Please refer to Figure 5 , Figure 6 and Figure 7 In a specific embodiment, the buffer module 161 is provided with an opening 160 , and the space where the opening 160 is located is arranged opposite to the first surface 111 of the main electrode 11 .

[0129] The buffer module 161 may be provided with an opening 160 in the middle, and the space where the opening 160 is located is arranged opposite to the first surface 111 of the main electrode 11, so that the main electrode 11 provided with the pore 113 is not completely blocked by the buffer module 161, especially the area provided with the pore 113 is not blocked by the buffer module 161. When water enters through the water inlet 101, it can flow into the area of ​​the main electrode 11 provided with the pore 113 through the opening 160, thereby carrying away the ozone water with a higher concentration in the pore 113 area and outputting it to the user's water terminal, thereby preventing the ozone water from forming dead water in the pore 113 area.

[0130] In addition, during the electrolysis reaction, the main electrode 11 itself has a certain resistance value, which will convert part of the electrical energy into heat energy. Taking the main electrode 11 as an example, if the main electrode 11 itself does not dissipate heat well, it may produce a large temperature rise, which is easy to scale and affect its service life. In this embodiment, the structure of the buffer module 161 provided with the opening 160 can be used to guide the external water flow to the main electrode 11 at a certain angle to flush the main electrode 11, so as to effectively dissipate heat for the main electrode 11 using running water and extend its service life.

[0131] Among them, the specific structure of the buffer module 161 can be adapted to the structure of the first conductor 14. For example, when the structure of the first conductor 14 is a rectangular frame, the buffer module 161 can also be a rectangular frame structure as a whole. Among them, the material of the buffer module 161 can be a flexible insulating material. Specifically, the buffer module 161 may include insulating rubber or an insulating spring. For example, the material of the buffer module 161 can be insulating rubber. When the material of the buffer module 161 is insulating rubber, on the one hand, it can utilize the deformable properties of the rubber to produce the above-mentioned buffering effect. On the other hand, when the buffer module 161 can be used as an insulating protective part of the first conductor 14, the compactness of the structure of the ozone generating device 100 is improved, and the safety during use is improved.

[0132] In this embodiment, a buffer 162 may also be provided between the auxiliary electrode 12 and the housing 10. The function of the buffer 162 may refer to the description of the buffer module 161, and the present application will not elaborate on it here.

[0133] Please refer to Figures 9 to 11 In an embodiment of the present application, a water supply device is also provided, and the water supply device may include the ozone generating device 100 described in any of the above embodiments.

[0134] For the water supply device, it may include a control circuit, the control circuit includes a switching circuit for switching the positive and negative poles of the main electrode and the auxiliary electrode, the switching circuit is configured as follows: when the switching circuit is in a first state, the main electrode is positive and the auxiliary electrode is negative; when the switching circuit is in a second state, the main electrode is negative and the auxiliary electrode is positive. The control circuit may include a time control module, the time control module is used to control the working time of the first state and the second state.

[0135] The water supply device can achieve the technical effect achieved by the implementation of the ozone generation device 100 by setting the ozone generation device 100. For details, please refer to the specific description of the implementation of the above-mentioned oxygen generation device, and this application will not repeat it here.

[0136] In the implementation manner of the present application, the water supply device may be any device that needs to use ozone water, and specifically, the water supply device may be any of the following: a hot water device 200, a water purification device, and a cleaning device, etc. In the implementation manner of the present application, the water supply device is mainly used in the hot water device 200 as an example for illustration. When the water supply device is used in other devices, adaptive adjustments can be made with reference to the above scenarios.

[0137] In some embodiments, when the water supply device is a hot water device 200, the ozone generating device 100 is disposed on the water inlet pipe 21 of the hot water device 200; or, the ozone generating device 100 is disposed on the water outlet pipe 22 of the hot water device 200; or, the ozone generating device 100 is disposed on the bypass pipe 23 of the hot water device 200, and the bypass pipe 23 is used to connect the water inlet pipe 21 and the water outlet pipe 22 of the hot water device 200.

[0138] like Fig. 9 As shown, the ozone generating device 100 is arranged on the water inlet pipe 21 of the water heater 200. In this way, the ozone generating device 100 will not come into contact with the hot water generated in the water heater 200, so that it will not be affected by the hot water, and the service life of the ozone generating device 100 can be reliably guaranteed.

[0139] like Fig.10 As shown, the ozone generating device 100 is arranged on the water outlet pipe 22 of the water heater 200, so that the ozone water generated by the ozone generating device 100 does not need to pass through the inside of the water heater 200, and its concentration will not be diluted by the water inside the water heater 200. Especially for a volumetric water heater 200 with a water tank, when the ozone generating device 100 is arranged downstream of the water tank, the water in the water tank can be prevented from diluting the ozone water generated by the ozone generating device 100.

[0140] like Fig.11 As shown, the ozone generating device 100 can be arranged on the bypass pipe 23 of the water heater 200, and the bypass pipe 23 is used to connect the water inlet pipe 21 and the water outlet pipe 22 of the water heater 200. In this way, the ozone generating device 100 can obtain all the advantages of the above two embodiments, and can avoid contact with the hot water generated in the water heater 200, so as not to be affected by the hot water, and reliably ensure the service life of the ozone generating device 100; it can also make the ozone water generated by the ozone generating device 100 not need to pass through the inside of the water heater 200, and its concentration will not be diluted by the water inside the water heater 200.

[0141] In some embodiments, the water heater 200 may include a housing, and the ozone generator 100 is disposed inside the housing or the ozone generator 100 is disposed outside the housing.

[0142] As for the water heater 200, it has a shell, and the ozone generator 100 in the present application can be arranged inside the shell or outside the shell. For example, in the case where the ozone generator 100 is arranged outside the shell, it can be modified for the existing water heater 200, and the water heater 200 having the function of generating ozone water can be obtained by installing the ozone generator 100 between the water inlet pipe 21 and the water outlet pipe 22 of the existing water heater 200, such as a three-way joint. Since the electrodes of the ozone generator 100 itself are consumable parts, they need to be replaced after a certain period of use. In order to ensure easy disassembly, the ozone water generator can be arranged outside the shell.

[0143] Of course, in the production process of new products, if there is originally a space for installing the ozone generating device 100 , the ozone generating device 100 can be installed in the housing, thereby ensuring the overall aesthetics of the water heater 200 .

[0144] It should be noted that, in the description of this application, the terms "first", "second", etc. are only used for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0145] The above-mentioned various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0146] The above are only a few embodiments of the present invention. Although the embodiments disclosed by the present invention are as above, the contents are only embodiments adopted for facilitating the understanding of the present invention and are not used to limit the present invention. Any technician in the technical field to which the present invention belongs can make any modification and change in the form and details of the implementation without departing from the spirit and scope disclosed by the present invention, but the scope of patent protection of the present invention shall still be subject to the scope defined by the attached claims.
