Description

Technical Field

[0001] This invention relates to the field of ozone water generation technology, and particularly to an ozone generating device, a water supply device, and a control method thereof. 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] When this ozone generator is applied to people's daily lives, it is necessary to comprehensively consider factors such as user experience, safety, cost, and the lifespan of the machine itself in order to better meet user needs. Summary of the Invention

The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0103] The present application provides an ozone generating device, a water supply device and a control method thereof, which can improve safety during use, reduce cost, prolong the service life of the machine, and improve the user's experience.

[0104] Please refer to Figures 1 to 7In the embodiments of the present application, the ozone generating device 100 can include a housing 10 provided with a water inlet 101 and a water outlet 102; a first electrode 11, a second electrode 12 and a proton exchange membrane 13 arranged in the housing 10, the proton exchange membrane 13 being arranged between the first electrode 11 and the second electrode 12; the first electrode 11 and the second electrode 12 are made of different materials; the ozone generating device 100 is configured to: when the first electrode 11 serves as a positive electrode and the second electrode 12 serves as a negative electrode, water flowing from the water inlet 101 can generate ozone when flowing through the first electrode 11 to form ozone water and be output from the water outlet 102; when the first electrode 11 serves as a negative electrode and the second electrode 12 serves as a positive electrode, water flowing from the water inlet 101 does not generate ozone when flowing through the second electrode 12.

[0105] In the embodiments of the present application, the ozone generating device 100 is provided with a housing 10 and a first electrode 11, a proton exchange membrane 13 and a second electrode 12 arranged in the housing 10, wherein the first electrode 11 and the second electrode 12 are made of different materials, and the first electrode 11 can be a working electrode during use. Specifically, when the first electrode 11 serves as a positive electrode and the second electrode 12 serves as a negative electrode, water flowing from the water inlet 101 can generate ozone when flowing through the first electrode 11 to form ozone water and be output outward. The second electrode 12 can be an auxiliary electrode. Specifically, when the first electrode 11 serves as a negative electrode and the second electrode 12 serves as a positive electrode, water flowing from the water inlet 101 does not generate ozone when flowing through the second electrode 12. In this way, when the first electrode 11 and the second electrode 12 alternately serve as positive electrodes, the ozone generating device 100 can only output ozone water when the first electrode 11 serves as a positive electrode. When the ozone water output section and the ozone water non-output section are combined, it is beneficial to reasonably control the concentration of ozone water output outward, greatly reducing the safety hazards that may be caused by excessive ozone water concentration during long-term use (for example, during bathing); at the same time, when the second electrode 12 serves as a positive electrode, the ozone generating device 100 does not generate ozone, at which time a material with lower cost can be selected as the second electrode 12, which can reduce the cost of the machine and prolong the service life of the machine, thereby better meeting the needs of users.

[0106] In the embodiment of the present application, when the first electrode 11 serves as the positive electrode and the second electrode 12 serves as the negative electrode, ozone can be generated to form ozone water to be outputted, and the surface area of the first electrode 11 can be preferably set, for example, larger than that in the case where ozone water can be generated when either one of the two electrodes serves as the positive electrode. In this way, the current density on the first electrode 11 can be reduced, the wear of the first electrode 11 can be effectively slowed down, and the service life of the first electrode 11 can be effectively and reliably prolonged.

[0107] In addition, since the second electrode 12 serves as the positive electrode, the ozone generating device 100 is in a reverse electrode state, and an acidic environment is generated in the reverse electrode state, which can neutralize the basic environment of the first electrode 11 serving as the positive electrode, and further slow down the generation of scale.

[0108] In the embodiment of the present application, the ozone generating device 100 can mainly include a housing 10, and a first electrode 11, a second electrode 12 and a proton exchange membrane 13 arranged in the housing 10.

[0109] The present application will be described in detail below with reference to specific drawings and embodiments.

[0110] Please refer to Figure 2 , Figure 4 and Figure 7 , the housing 10 can include a base 110 and an end cover 120 which are detachably connected. The housing 10 has a receiving cavity formed by the base 110 and the end cover 120. The first electrode 11, the proton exchange membrane 13 and the second electrode 12 are located in the receiving cavity. The detachable connection between the base 110 and the end cover 120 can be screw connection, for example, screw 18 connection. Figure 7 As shown in FIG. 1, when the base 110 and the end cover 120 are connected by the screw 18, screw holes can be evenly arranged around the end cover 120 and the base 110, respectively, and the screw 18 is installed in the screw holes to connect the base 110 and the end cover 120. The number of the screw 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 similar to rectangular, the number of the screw 18 can be four, and the four screws 18 are distributed on the four corners of the end cover 120.

[0111] Of course, the detachable connection between the base 110 and the end cover 120 can also include snap connection or other forms, and is not limited to the above description. Those skilled in the art can make other changes under the inspiration of the technical essence of the present application, as long as the functions and effects achieved are the same or similar to those of the present application, which should be covered by the protection scope of the present application.

[0112] The shell 10 is provided with a water inlet 101 and a water outlet 102. The water inlet 101 and the water outlet 102 can be respectively communicated with the containing cavity. The water inlet 101 is arranged at any one of the following positions: the base 110, the end cover 120, and the base 110 and the end cover 120; and the water outlet 102 is arranged at any one of the following positions: the base 110, the end cover 120, and the base 110 and the end cover 120.

[0113] Specifically, the water inlet 101 can be arranged on the base 110, which can be an opening formed on the base 110; or the water inlet 101 can be formed after the base 110 and the end cover 120 are assembled, for example, the water inlet 101 can be a gap formed on the base 110, and / or the water inlet 101 can be a gap formed on the end cover 120; or the water inlet 101 can be an opening formed on the end cover 120.

[0114] Specifically, the water outlet 102 can be arranged on the base 110, which can be an opening formed on the base 110; or the water outlet 102 can be formed after the base 110 and the end cover 120 are assembled, for example, the water outlet 102 can be a gap formed on the base 110, and / or the water outlet 102 can be a gap formed on the end cover 120; or the water outlet 102 can be an opening formed on the end cover 120.

[0115] The first electrode 11 can be a working electrode. When the first electrode 11 is used as a positive electrode and the second electrode 12 is used as a negative electrode, water flowing from the water inlet 101 can generate ozone when flowing through the first electrode 11 to form ozone water for external output.

[0116] Specifically, the first electrode 11 can include any one of a boron-doped diamond electrode, a tin dioxide electrode, a lead dioxide electrode, and a platinum electrode.

[0117] The material of the first electrode 11 can be selected from noble metal oxides. In addition to the above-mentioned boron-doped diamond electrode, tin dioxide electrode, lead dioxide electrode, and platinum electrode materials, other noble metal oxide materials can also be selected for the first electrode 11. Overall, the material of the first electrode 11 can be selected to have a long service life and relatively low cost under the premise of meeting the reliability and safety requirements.

[0118] The second electrode 12 can be an auxiliary electrode, when the first electrode 11 is a negative electrode and the second electrode 12 is a positive electrode, water flowing from the water inlet 101 does not generate ozone when flowing through the second electrode 12, and the second electrode 12 can be used to reverse the polarity to adapt the ozone water concentration output by the ozone generator 100 to meet the needs of the user. In addition, the first electrode 11 is an auxiliary electrode for reversing the polarity, and the corresponding material cost is lower.

[0119] Specifically, the second electrode 12 can 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.

[0120] The second electrode 12 can be a metal electrode or a non-metal electrode or an oxide coating electrode that is different in material from the first electrode 11. Specifically, in addition to the above-mentioned stainless steel electrode, titanium and titanium alloy electrode, zirconium and zirconium alloy electrode, carbon electrode, and oxide coating electrode, other materials can also be selected for the second electrode 12.

[0121] In some embodiments, the first electrode 11 and the second electrode 12 are connected to a control circuit, which is provided on the ozone generator 100 or is separate from the ozone generator 100, or part of the function modules of the control circuit are provided on the ozone generator 100, and the rest of the function modules are separate from the ozone generator 100.

[0122] In the present embodiment, the ozone generator 100 can also be connected to a control circuit. The control circuit is connected to the first electrode 11 and the second electrode 12, respectively, so that the voltage / current applied by the power supply module can be applied to the first electrode 11 and the second electrode 12.

[0123] Specifically, the control circuit can be provided in a variety of ways, for example, the control circuit can be provided on the ozone generator 100. Alternatively, the control circuit can be separate from the ozone generator 100, for example, it can be provided in the controller of the specific device to which the ozone generator 100 is applied. Alternatively, the control circuit can include multiple function modules, for example, a first function module, a second function module, or more function modules, and the present application takes two parts as an example. The first function module can be provided on the ozone generator 100, and the second function module can be separate from the ozone generator 100, for example, it can be provided in the controller of the specific device to which the ozone generator 100 is applied.

[0124] One of the function modules in the control circuit can be used to realize the switching of the positive and negative poles of the first electrode 11 and the second electrode 12.

[0125] In one embodiment, the control circuit can include a switching circuit for switching the positive and negative poles of the first electrode 11 and the second electrode 12, and the switching circuit is configured to: when the switching circuit is in a first state, the first electrode 11 is a positive pole and the second electrode 12 is a negative pole; and when the switching circuit is in a second state, the first electrode 11 is a negative pole and the second electrode 12 is a positive pole.

[0126] In the present embodiment, the switching circuit can include two states, a first state and a second state, and when the switching circuit is in different states, the polarities applied to the first electrode 11 and the second electrode 12 are opposite. When the switching circuit is in the first state, it can connect the first electrode 11 to the positive pole of the power supply module and connect the second electrode 12 to the negative pole of the power supply module, at which time the first electrode 11 is a positive pole and the second electrode 12 is a negative pole. When the switching circuit is in the second state, it can connect the first electrode 11 to the negative pole of the power supply module and connect the second electrode 12 to the positive pole of the power supply module, at which time the first electrode 11 is a negative pole and the second electrode 12 is a positive pole.

[0127] The specific configuration of the switching circuit can include, for example, a mos tube, a single-pole double-throw switch, or other components with switching functions. Of course, the specific configuration of the switching circuit is not limited to the above description, and those skilled in the art can make other changes under the technical essence of the present application, as long as the functions and effects achieved are the same or similar to the present application, which should be covered within the protection scope of the present application. For example, when the single-pole double-throw switch is in the first connection position and the first circuit is connected, the switching circuit is in the first state; when the single-pole double-throw switch is in the second connection position and the second circuit is connected, the switching circuit is in the second state.

[0128] Further, the control circuit includes a timing module for controlling the working time of the first state and the second state.

[0129] In the embodiment, one function module of the control circuit is used to control the working time length of the first state and the second state, that is, the time length of generating ozone water with the first electrode 11 as an anode and the second electrode 12 as a cathode, and the time length of not generating ozone water with the first electrode 11 as a cathode and the second electrode 12 as an anode. Through the control of the working time length of the first state and the second state, the time length of generating ozone water and the time length of not generating ozone water 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 use demand of the user, and the use experience of the user is improved.

[0130] As shown in Figure 7 In some embodiments, the ozone generation device 100 can further include a first conductor 14 and a second conductor 15, the first conductor 14 is connected with the first electrode 11, and the second conductor 15 is connected with the second electrode 12. The power supply module can supply power to the ozone generation device 100 through the first conductor 14 and the second conductor 15.

[0131] In the embodiment, in order to apply the voltage / current provided by the external power supply module to the first electrode 11 and the second electrode 12, the ozone generation device 100 is further provided with the first conductor 14 and the second conductor 15. The first conductor 14 can be used to electrically connect the power supply module with the first electrode 11, so that the power supply module can supply power to the first electrode 11; the second conductor 15 can be used to electrically connect the power supply module with the second electrode 12, so that the power supply module can supply power to the second electrode 12. The power supply module is connected with an external power source and connected with the first electrode 11 and the second electrode 12.

[0132] The first conductor 14 can include a conductive frame 142 and a first conductive column 141. The conductive frame 142 can be a hollow frame structure, and the outer contour thereof can be matched with the outer contour of the first electrode 11. For example, when the outer contour of the first electrode 11 is rectangular, the conductive frame 142 can be a rectangular frame. Of course, the structure of the first electrode 11 and the specific structure of the conductive frame 142 can also be other shapes, and the application does not specifically limit the structure thereof. In the embodiments and drawings of the application, the conductive frame 142 is mainly exemplified as a rectangular frame when the outer contour of the first electrode 11 is rectangular.

[0133] 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 the short sides of the rectangular frame is in contact with the first electrode 11, so as to be able to apply the voltage / current provided by the power supply module to the first electrode 11. A connecting portion is arranged 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 of the first conductive column 141 extends out of the shell 10 to be connected to the power supply module. The external power supply module can apply voltage / current to the first electrode 11 through the first conductive column 141 and the conductive frame 142.

[0134] For the rectangularly configured first electrode 11 and the conductive frame 142, in order to prolong the contact time of the water flow with the electrode and ensure that the electrolysis reaction is carried out sufficiently, the water inlet 101 and the water outlet 102 are arranged opposite to each other along the long side direction of the first electrode 11 and the conductive frame 142. At this time, in order to prevent the first conductive column 141 from interfering with the 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 part of the protrusion formed on the long side of the conductive frame 142.

[0135] In the present embodiment, the second conductive body 15 can be arranged separately from the second electrode 12. When the second conductive body 15 is arranged separately from the second electrode 12, the specific composition and connection relationship of the second conductive body 15 can refer to the specific description of the first conductive body 14, and the present application will not be described again here.

[0136] As shown in FIG. 1, Figure 7 In one specific embodiment, considering that the second electrode 12 in the present embodiment is an auxiliary electrode for reverse polarity, the second conductive body 15 can be integrally formed with the second electrode 12.

[0137] In the present embodiment, the material of the second electrode 12 can be the same as the material of the second conductive body 15, so that the second conductive body 15 and the second electrode 12 can be integrally formed. When the second conductive body 15 and the second electrode 12 are integrally formed, the structure of the ozone generating device 100 can be simplified, the volume of the ozone generating device 100 can be reduced, and compared with the embodiment in which the second conductive body 15 and the second electrode 12 are arranged separately, 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.

[0138] Please refer to Figure 3 and Figure 7A connecting portion is arranged on one side of the second electrode 12, and the second conductive column 151 is connected to the connecting portion. One end of the second conductive column 151 is connected to the connecting portion, and the other end of the second conductive column 151 extends out of the shell 10 to be connected to a power supply module. The external power supply module can apply voltage / current to the second electrode 12 through the second conductive column 151.

[0139] In one embodiment, the first electrode 11 is a boron-doped diamond electrode, and the first electrode 11 is directly attached to the first conductive body 14 to electrically connect the first electrode 11 and the first conductive body 14, and the first electrode 11 and the first conductive body 14 are not mechanically connected.

[0140] In the embodiment, the first electrode 11 can be a silicon-based boron-doped diamond electrode or a boron-doped diamond electrode formed by depositing a coating on the surface of another base material. For the boron-doped diamond electrode, when it is used as a cathode, fouling can be avoided by reversing the electrode, thereby prolonging the service life.

[0141] For the boron-doped diamond electrode, it cannot be fixedly connected by traditional mechanical connection methods such as welding and threaded connection. In order to ensure that the first conductive body 14 can be reliably connected to the first electrode 11 without mechanical connection, so as to apply the voltage / current provided by the external power supply module to the first electrode 11, the first conductive body 14 is arranged separately from the first electrode 11 and directly attached to the first electrode 11, thereby electrically connecting the first electrode 11 and the first conductive body 14.

[0142] In one embodiment, the first electrode 11 is a boron-doped diamond electrode, and a buffer module 161 is arranged between the first electrode 11 and the shell 10, and the buffer module 161 is configured to have an adjustable compression amount.

[0143] In the embodiment, the first electrode 11 can be a silicon-based boron-doped diamond electrode or a boron-doped diamond electrode formed by depositing a coating on the surface of another base material. For the boron-doped diamond electrode, when it is used as a cathode, fouling can be avoided by reversing the electrode, thereby prolonging the service life.

[0144] For example, the silicon-based boron-doped diamond electrode, since the main component of the material is silicon-based material, which is a brittle material, is easy to break under external force. In order to protect the first electrode 11 and effectively position the first electrode 11, and ensure that the first electrode 11 and the proton exchange membrane 13 always reliably contact, a buffer module 161 can be provided between the first electrode 11 and the shell 10. For example, the buffer module 161 can be provided between the first electrode 11 and the end cover 120. Of course, when other brittle matrix materials are used as the main component to form a boron-doped diamond electrode, a buffer module 161 also needs to be provided to achieve the same or similar technical effects.

[0145] The buffer module 161 can be a structure with adjustable compression amount. During assembly of the end cover 120 and the base 110, the buffer module 161 can adjust its compression amount to produce corresponding deformation, which can ensure reliable fitting of the first conductive body 14 and the first electrode 11. The deformation of the buffer module 161 itself can also release excessive force generated during production and assembly, preventing the force from being transmitted to the electrode and damaging the electrode. In a specific scenario, the fastening force between the end cover 120 and the base 110 is uneven during assembly. For example, when the end cover 120 and the base 110 are connected by a screw 18, the number of turns of the screw 18 may

[0146] In addition, in some embodiments, the ozone generation device 100 can also include a mounting rack 17. The first electrode 11 and the second electrode 12 are respectively limited on both sides of the mounting rack 17; the buffer module 161 and the buffer 162 are respectively fixed on both sides of the mounting rack 17 and respectively press and limit the first electrode 11 and the second electrode 12. The mounting rack 17 can be a rectangular frame structure, and the rectangular frame structure has limiting columns on both sides. The first electrode 11 and the second electrode 12 are positioned and supported by the mounting rack 17 under the limiting action of the limiting columns. The mounting rack 17 is an insulating member, for example, the material thereof can be plastic.

[0147] In some embodiments, the first electrode 11 is a plate with a predetermined thickness, the first electrode 11 has a first surface 111 and a second surface 112 along the thickness direction, and the first electrode 11 is provided with an aperture 113 penetrating the first surface 111 and the second surface 112. The proton exchange membrane 13 is a complete sheet structure. The second electrode 12 is a complete plate with a predetermined thickness.

[0148] In this embodiment, the first electrode 11 may be in the form of a plate. The thickness of the first electrode 11 may vary depending on the material and manufacturing process used. This application does not impose a specific numerical limit on the thickness.

[0149] A through-hole 113 is provided on the first electrode 11 along its thickness direction. The proton exchange membrane 13 is a complete sheet without any pores. When the first electrode 11 is the anode, the pores 11 can be used to enlarge the perimeter of the three-phase interface between the first electrode 11, water, and the proton exchange membrane 13, thereby improving the efficiency of the electrolysis reaction. Furthermore, the presence of pores 113 on the first electrode 11 facilitates the efficient outward discharge of ozone water generated at the three-phase interface between the first electrode 11, water, and the proton exchange membrane 13 towards the side away from the proton exchange membrane 13.

[0150] The shape, structure, size, and distribution of the pores 113 can vary depending on the direction of water flow, the structure of the first electrode 11, and the performance requirements of the ozone generating device. For example, Figure 8 As shown, the first electrode 11 can be a rectangular structure with opposite length and width directions. The dimension of the main electrode in the length direction is larger than the dimension in the width direction. The aperture 113 can be a strip-shaped hole extending along the width direction, and there can be multiple strip-shaped holes arranged at intervals along the length direction. Specifically, the strip-shaped hole can be a rectangular hole with equal width, or it can be an oblong hole with unequal width, etc.

[0151] When water enters the containment cavity from the inlet 101, it flows through the first electrode 11. Since the direction of water flow forms a certain angle with the direction of extension of the pore 113, for example, it is roughly perpendicular, 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.

[0152] For the first electrode 11, a noble metal oxide layer (coating) is deposited on its second surface 112 facing the proton exchange membrane 13. This noble metal oxide layer is gradually consumed during use. Theoretically, the surface area of ​​this noble metal oxide layer is proportional to its service life.

[0153] Meanwhile, for the first electrode 11 with pores 113, the perimeter of the pores 113 is beneficial to increasing the perimeter of the three-phase interface when the first electrode 11 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 113, the better the effect on improving the efficiency of the electrolysis reaction.

[0154] The ratio of the effective area of the first electrode 11 to the surface area thereof can be between 15% and 95% in order to meet the requirements of the service life of the first electrode 11 and the efficiency of the electrolytic reaction of the first electrode 11 as an anode.

[0155] In addition, the second electrode 12 can be in the form of a sheet, specifically, the second electrode 12 is not provided with a hole structure and is in the form of a complete sheet. The structure of the complete sheet is simple in manufacturing process and low in manufacturing cost. In addition, the process can be reduced and the defective rate can be reduced due to the absence of additional punching.

[0156] For the first electrode 11 and the second electrode 12 in the form of a sheet and the proton exchange membrane 13 in the form of a sheet, the second surface 112 of the first electrode 11 is attached to one surface of the proton exchange membrane 13, and the second electrode 12 is attached to the other surface of the proton exchange membrane 13. In this way, the first electrode 11 and the second electrode 12 can be in sufficient contact with the proton exchange membrane 13.

[0157] In the embodiment, the first electrode 11 is in direct contact with the proton exchange membrane 13. When the first electrode 11 is an anode, ozone is generated at the three-phase interface of water, the proton exchange membrane 13 and the main electrode 11. The direct contact shortens the migration path of the conductive ions, accelerates the electrolytic reaction, rapidly generates ozone, and thus effectively improves the ozone generation efficiency of the ozone generation device 100.

[0158] In the embodiment, the first electrode 11 is in direct contact with the proton exchange membrane 13. When the first electrode 11 is an anode, ozone is generated at the three-phase interface of water, the proton exchange membrane 13 and the main electrode 11. The direct contact shortens the migration path of the conductive ions, accelerates the electrolytic reaction, rapidly generates ozone, and thus effectively improves the ozone generation efficiency of the ozone generation device 100.

[0159] In addition, for the first electrode 11 provided with the apertures 113, the length of the periphery of the entire first electrode 11 gradually decreases, and the length of the periphery of the apertures 113 gradually increases during use. The increase in the length of the periphery of the apertures 113 can compensate for the decrease in the length of the periphery of the entire first electrode 11, and thus the first electrode 11 can have a high electrolytic reaction efficiency as an anode.

[0160] In addition, the auxiliary electrode 12 can be attached to the other surface of the proton exchange membrane 13, so as to form a compact electrode assembly, which is beneficial to the positioning and installation of the electrode assembly as a whole.

[0161] 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 opposite to the first surface 111 of the first electrode 11.

[0162] In the embodiment, the first electrode 11 can be a plate with a predetermined thickness, and has a first surface 111 and a second surface 112 in the thickness direction of the first electrode 11, wherein the second surface 112 is the surface attached to the proton exchange membrane 13. The first surface 111 is the surface opposite to the proton exchange membrane 13.

[0163] The middle part of the buffer module 161 can be provided with an opening 160, and the space where the opening 160 is located is opposite to the first surface 111 of the first electrode 11. The first electrode 11 provided with the apertures 113 can not be completely blocked by the buffer module 161, especially the area provided with the apertures 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 first electrode 11 provided with the apertures 113 through the opening 160, so as to carry away the ozone water with higher concentration in the aperture 113 area, and output to the user's water terminal, avoiding the formation of dead water in the aperture 113 area.

[0164] In addition, during the electrolysis reaction, the first electrode 11 and the like itself has a certain resistance, which can convert part of the electric energy into heat energy. Taking the first electrode 11 as an example, if the first electrode 11 itself has poor heat dissipation, it may have a large temperature rise, which can easily cause scaling and affect its service life. In the embodiment, the buffer module 161 provided with the opening 160 can guide the external water flow to the first electrode 11 at a certain angle, so as to flush the first electrode 11, thereby effectively dissipating heat from the first electrode 11 by using running water, and prolonging the service life of the first electrode 11.

[0165] The specific structure of the buffer module 161 can be adapted to the structure of the first conductive body 14. For example, when the structure of the first conductive body 14 is a rectangular frame, the buffer module 161 can also have a rectangular frame structure as a whole. The material of the buffer module 161 can be a flexible material. Specifically, the material of the buffer module 161 can include insulating rubber or insulating spring. For example, the material of the buffer module 161 can be insulating rubber. When the buffer module 161 is insulating rubber, on the one hand, it can utilize the deformable performance of rubber to generate the above-mentioned buffering effect, and on the other hand, it can serve as an insulating protective piece of the first conductive body 14, improve the compactness of the structure of the ozone generating device 100, and the safety in use.

[0166] In the present embodiment, a buffer piece 162 can also be arranged between the second electrode 12 and the housing 10. The functions and the like of the buffer piece 162 can refer to the description of the buffer module 161 above, and will not be described here in detail.

[0167] Please refer to Figures 9 to 11 The present embodiment also provides a water supply device, which can include the ozone generating device 100 of any of the above-mentioned embodiments.

[0168] For the water supply device, the control circuit includes a switching circuit for switching the positive and negative poles of the first electrode 11 and the second electrode 12, and the switching circuit is configured to: when the switching circuit is in a first state, the first electrode 11 is a positive pole and the second electrode 12 is a negative pole; when the switching circuit is in a second state, the first electrode 11 is a negative pole and the second electrode 12 is a positive pole. The control circuit can include a timing module for controlling the working time of the first state and the second state.

[0169] The water supply device can achieve the technical effects realized by the ozone generating device 100 by arranging the ozone generating device 100. For details, please refer to the specific description of the above-mentioned ozone generating device embodiment, which will not be described here in detail.

[0170] In some embodiments, the working time of the first state and the second state can be actively adjusted by the user or set to a fixed time length.

[0171] In the embodiment, when the switching circuit is in the first state, the first electrode 11 is a positive electrode and the second electrode 12 is a negative electrode, and water flowing from the water inlet 101 can generate ozone when flowing through the first electrode 11 to form ozone water and output from the water outlet 102. When the switching circuit is in the second state, the first electrode 11 is a negative electrode and the second electrode 12 is a positive electrode, and water flowing from the water inlet 101 does not generate ozone when flowing through the second electrode 12.

[0172] In this way, by controlling the working time length of the first state and the second state, the proportion of the time length of generating ozone water by the ozone generating device 100 can be adjusted, and thus the concentration of ozone water supplied to the water terminal of the user can be adjusted.

[0173] The working time length of the first state and the second state can be a fixed time length. For example, the fixed time length can be stored in the machine, so as to output ozone water with a predetermined concentration to the user. In addition, the working time length of the first state and the second state can be an adjustable time length. For example, the working time length of the first state and the second state can be controlled by the timing module, so as to meet different ozone water concentration requirements of the user. Specifically, the user can adjust the working time length of the first state and the second state according to the user's own use requirements. For example, when the user needs to increase the concentration of ozone water, the proportion of the first time length (the ratio of the first time length to the sum of the first time length and the second time length) can be increased, that is, the proportion of the time length of generating ozone water can be increased; when the user needs to reduce the concentration of ozone water, the proportion of the first time length can be reduced, that is, the proportion of the time length of generating ozone water can be reduced.

[0174] In the embodiments of the present application, the water supply device can be any device that needs to use ozone water. Specifically, the water supply device can be any one of the following: a hot water device 200, a water purification device, a cleaning device, and the like. In the embodiments of the present application, the water supply device is mainly taken as an example of being applied to the hot water device 200. When the water supply device is applied to other devices, the above-mentioned scenarios can be adjusted adaptively.

[0175] In some embodiments, the water supply device has a first working mode and a second working mode. In the first working mode, the first state and the second state are alternately executed. In the second working mode, only the first state is executed. In addition, the water supply device can also have a third working mode, which is a mode selected by the user not to use ozone water. In the third working mode, only the second state is executed.

[0176] In the embodiment, the water supply device can include multiple different working modes, for example, it can include: a first working mode in which the first state and the second state are alternately executed, a second working mode in which only the first state is executed, and a third working mode in which only the second state is executed.

[0177] When the first working mode is started, the first state and the second state are alternately executed, and ozone water is intermittently generated; when the second working mode is started, only the first state is executed, and ozone water can be continuously generated; when the third working mode is started, only the second state is executed, no ozone water is generated, and the polarity can be reversed to prevent fouling.

[0178] Among them, the ozone concentration in the first working mode is less than or equal to the ozone concentration in the second working mode.

[0179] When the first working mode is started, the first state and the second state are alternately executed, and ozone water is intermittently generated; when the second working mode is started, only the first state is executed, and ozone water can be continuously generated; when the third working mode is started, only the second state is executed, no ozone water is generated, and the polarity can be reversed to prevent fouling.

[0180] When the voltage or current applied by the power supply module to the ozone generating device 100 in the first working mode is equal to the voltage or current applied by the power supply module to the ozone generating device 100 in the second working mode, because in the second working mode only the first state of generating ozone water is executed, the ozone concentration in the first working mode is generally less than the ozone concentration in the second working mode.

[0181] Or, when the voltage or current applied by the power supply module to the ozone generating device 100 in the first working mode is less than the voltage or current applied by the power supply module to the ozone generating device 100 in the second working mode, because in the second working mode only the first state of generating ozone water is executed, the ozone concentration in the first working mode is also less than the ozone concentration in the second working mode.

[0182] Of course, it is also not excluded that in some cases, when the power or current applied by the power supply module to the ozone generating device 100 in the first working mode is greater than the power or current applied by the power supply module to the ozone generating device 100 in the second working mode, the ozone concentration in the first working mode can be equal to the ozone concentration in the second working mode.

[0183] Taking the water supply device as an example, the first working mode can be a daily mode, which provides ozone water with a more appropriate ozone concentration to the user, and can be used to meet the user's use demand of bathing, etc. The second working mode can be a forced mode, which provides ozone water with a higher ozone concentration to the user, and can be used to meet the use demand of local cleaning such as gargling.

[0184] In some embodiments, the water supply device can include a first working condition and a second working condition which can be selected by a user; when the user selects the first working condition, the water supply device executes the first working mode or the second working mode; when the user selects the second working condition, the water supply device executes the third working mode under a predetermined condition.

[0185] In the present embodiment, the water supply device can include multiple working conditions, such as at least a first working condition and a second working condition, wherein when the user selects the first working condition, it indicates that there is a current demand for using ozone water; at this time, the water supply device executes the first working mode or the second working mode; when the user selects the second working condition, it indicates that there is no current demand for using ozone water, at this time, the water supply device can determine whether the predetermined condition is met, and if the predetermined condition is met, the second state of not generating ozone water is executed, i.e., the third working mode for reversing the polarity is executed.

[0186] The predetermined condition can be that the water supply device has executed the second working mode under the first working condition selected by the user before the user selects the second working condition.

[0187] When the user selects the second working mode under the first working condition, since only the first state of generating ozone water is executed in the second working mode, in order to prolong the service life of the ozone generating device 100 and slow down the generation of scale, the third working mode can be executed to reverse the polarity.

[0188] In order to neutralize the alkaline environment generated by the ozone generating device 100 when only the first state is executed in the second working mode by the acidic environment generated by the third working mode which only executes the second state, the working time of the third working mode is greater than or equal to the working time of the second working mode.

[0189] In some embodiments, when the water supply device is a hot water device 200, the ozone generating device 100 is arranged on the water inlet pipeline 21 of the hot water device 200; or, the ozone generating device 100 is arranged on the water outlet pipeline 22 of the hot water device 200; or, the ozone generating device 100 is arranged on the bypass pipeline 23 of the hot water device 200, and the bypass pipeline 23 is used to connect the water inlet pipeline 21 and the water outlet pipeline 22 of the hot water device 200.

[0190] As shown in Figure 9 The ozone generating device 100 is arranged on the water inlet pipeline 21 of the hot water device 200, so that the ozone generating device 100 will not be in contact with the hot water generated in the hot water device 200, thereby not being affected by the hot water and reliably ensuring the service life of the ozone generating device 100.

[0191] AsFigure 10 As shown, the ozone generator 100 is installed on the outlet pipe 22 of the hot water device 200. Thus, the ozone-generating water produced by the ozone generator 100 does not need to pass through the interior of the hot water device 200, and its concentration is not diluted by the water inside the hot water device 200. Especially for a volumetric hot water device 200 with a water tank, when the ozone generator 100 is located downstream of the water tank, the dilution effect of the water in the tank on the ozone-generating water produced by the ozone generator 100 can be avoided.

[0192] like Figure 11 As shown, the ozone generating device 100 can be installed on the bypass pipe 23 of the hot water device 200. The bypass pipe 23 is used to connect the inlet pipe 21 and the outlet pipe 22 of the hot water device 200. In this way, the ozone generating device 100 can obtain all the advantages of the above two embodiments. It can avoid contact with the hot water generated in the hot water device 200, so it is not affected by the hot water and its service life can be reliably guaranteed. It can also make the ozone water generated by the ozone generating device 100 not need to pass through the inside of the hot water device 200, and its concentration will not be diluted by the water inside the hot water device 200.

[0193] In some embodiments, the hot water device 200 may include a housing, with the ozone generating device 100 disposed inside the housing or outside the housing.

[0194] The hot water device 200 has a housing, and the ozone generating device 100 of this application can be installed inside or outside the housing. For example, if the ozone generating device 100 is installed outside the housing, an existing hot water device 200 can be modified. By installing the ozone generating device 100 between the inlet pipe 21 and outlet pipe 22 of the existing hot water device 200, for example, a T-junction, a hot water device 200 with ozone water generation function can be obtained. Since the electrode of the ozone generating device 100 itself is a consumable component, it needs to be replaced after a certain period of use. To ensure easy disassembly, the ozone generating device 100 can be installed outside the housing.

[0195] Of course, if there is already space available for the ozone generator 100 during the production of the new product, the ozone generator 100 can be installed inside the casing to ensure the overall aesthetics of the hot water device 200.

[0196] In some embodiments, when the water supply device is a water purification device, the water purification device comprises a water purification branch and a domestic water branch, and the ozone generator 100 is arranged on the water purification branch or the ozone generator 100 is arranged on the domestic water branch.

[0197] The water purification branch of the water purification device is sequentially provided with a PP filter core, a carbon fiber filter core, and a reverse osmosis filter core. Of course, the specific configuration of the water purification branch can also be different according to the specific configuration of different water purification devices, and is not limited to the above description. Those skilled in the art can also make other changes under the inspiration of the technical essence of the present application, as long as the functions and effects achieved are the same or similar to the present application, which should be covered within the protection scope of the present application.

[0198] When the ozone generator 100 is installed on the above-mentioned water purification branch, the ozone generator 100 can be arranged after the PP filter core, or the ozone generator 100 is arranged after the carbon fiber filter core, or the ozone generator 100 is arranged after the reverse osmosis filter core.

[0199] For example, when the ozone generator 100 is arranged after the reverse osmosis filter core, it can be connected to the water purification branch between the reverse osmosis filter core and the water outlet faucet.

[0200] For example, when the ozone generator 100 is arranged after the carbon fiber filter core, a branch can be led downstream of the carbon fiber filter core as a domestic water branch, and the ozone generator 100 can be arranged on the branch.

[0201] For example, when the ozone generator 100 is arranged after the PP filter core, a branch can be led downstream of the PP filter core as a domestic water branch, and the ozone generator 100 can be arranged on the branch. The water filtered by the PP filter core is electrolyzed by the ozone generator 100, which can improve the service life of the ozone generator 100.

[0202] In theory, the ozone generator 100 is arranged downstream of the carbon fiber filter core, and the water quality is further improved under the filtering effect of the carbon fiber filter core, so that the service life of the ozone generator 100 is further improved. However, considering that the service life of the carbon fiber filter core is relatively short, generally shorter than that of the PP filter core, and the domestic water consumption is large, if all the raw water supplied to the water purification device passes through the carbon fiber filter core, the service life of the carbon fiber filter core will be greatly shortened, frequent replacement of the filter core will increase the use cost of the user and reduce the use experience of the user. Therefore, the ozone generator 100 is preferably arranged downstream of the PP filter core, which can improve the service life of the ozone generator 100 and ensure the service life of the filter core.

[0203] In some embodiments, when the water supply device is a cleaning device, the ozone generating device 100 is arranged on the water inlet pipeline 21 of the cleaning device.

[0204] In the present embodiment, the cleaning device can be a household appliance such as a dishwasher. Of course, the cleaning device can also be in other forms.

[0205] In order to improve the cleaning effect and prevent the tableware from being scaled after being cleaned by the cleaning device, the cleaning device can include a water softening module. The ozone generating device 100 can be arranged after the water softening module, or the ozone generating device 100 and the water softening module are arranged in parallel.

[0206] When the ozone generating device 100 is arranged after the water softening module, the water softening module can purify the water before it enters the ozone generating device 100, removing calcium and magnesium ions, so as to improve the water quality entering the ozone generating device 100, thereby prolonging the service life of the ozone generating device 100.

[0207] The present application also provides a control method applied to any of the above-mentioned water supply devices. The water supply device has a first working mode and a second working mode; in the first working mode, the first state and the second state are executed alternately; in the second working mode, only the first state is executed.

[0208] Referring to Figure 12 , the control method can include the following steps:

[0209] Step S10: obtaining the working mode selected by the user;

[0210] Step S12: obtaining the water flow rate flowing through the ozone generating device 100; if the water flow rate is greater than a first preset flow rate, starting the ozone generating device 100 to work.

[0211] In the present embodiment, the water supply device has multiple different working modes, and the working state, corresponding required working parameters, etc. are different in different working modes.

[0212] When receiving the start signal issued by the user, the working mode currently selected by the user can be identified from the start signal. For example, when the start signal triggered by the user indicates that the first working mode is currently started by the user, the ozone generating device 100 is controlled to work according to the first working mode; when the start signal triggered by the user indicates that the second working mode is currently started by the user, the ozone generating device 100 is controlled to work according to the second working mode; when the start signal triggered by the user indicates that the third working mode is currently started by the user, the ozone generating device 100 is controlled to work according to the third working mode.

[0213] Before starting the ozone generator 100 to work, the water flow rate flowing through the ozone generator 100 can be obtained, and the ozone generator 100 is started after the water flow rate is greater than a first preset flow rate. The first preset flow rate can be a safe flow rate for starting the ozone generator 100.

[0214] Specifically, to ensure user safety, the first preset flow rate is greater than 0.5 L / min. For example, the voltage / current is applied to the ozone generator 100 to generate ozone by electrolysis only when the water flow rate is greater than 1 L / min (liters per minute), that is, the ozone generator 100 is started only when there is a flow signal, to prevent damage and safety problems such as short circuit, burning, and the like caused by electrode operation without water.

[0215] In one case, the control method comprises:

[0216] If the user selects the first working mode and the water flow rate is greater than the first preset flow rate, the first current and / or the first voltage required by the ozone generator 100 are determined according to the water flow rate and the first target ozone concentration in the first working mode.

[0217] The power supply module is controlled to apply the first current and / or the first voltage to the ozone generator 100.

[0218] In this embodiment, the water supply device can store working parameters required for each working mode. The number of working parameters can be one or more groups. For example, in the first working mode, the first target ozone concentration and the corresponding relationship between the first current and / or the first voltage required by the ozone generator 100 are stored. The corresponding relationship can be a continuously stored function relationship, an intermittently stored table, or other forms, which are not limited in this application.

[0219] When it is identified that the user currently selects the first working mode and the water flow rate flowing through the ozone generator 100 is greater than the first preset flow rate, the first current and / or the first voltage required to be applied to the ozone generator 100 can be determined according to the current water flow rate and the target ozone concentration in the current mode. The current / voltage applied to the ozone generator 100 is positively correlated with the water flow rate through the ozone generator 100.

[0220] After the first current and / or the first voltage required to be applied to the ozone generator 100 are determined, the power supply module is controlled to apply the first current and / or the first voltage to the ozone generator 100 to form ozone water with the first target ozone concentration.

[0221] If the user selects the first working mode, the first state and the second state are controlled to work alternately in the first working mode; the working duration of the first state is a first duration, and the working duration of the second state is a second duration. The first duration and the second duration are fixed durations or variable durations.

[0222] In a preset time period, the cumulative duration of the first duration is less than or equal to a first preset duration.

[0223] The preset time period can be a time period for a single use of the user, for example, a time period for completing a bath. Specifically, the time period can be 20 min-60 min. The first preset duration is a maximum value of the time for outputting ozone water. The first preset duration is generally less than the time period for a single use, for example, can be 10 min-40 min. In this way, it can be ensured that the time for outputting ozone water in the use process of the user, for example, in the time period for completing a bath, cannot exceed an upper limit value, thereby preventing excessive ozone water and affecting safety.

[0224] In a specific embodiment, when the first duration and the second duration are variable durations, the ratio of the first duration and the second duration decreases with the water use process of the user.

[0225] In a specific scenario, for example, in the bath process of the user, the user wants to use ozone water with a relatively high concentration to first sterilize and clean, and then gradually reduce the concentration of the ozone water, and then use clean water to rinse. In order to meet the bath needs of the user and improve the use experience of the user, the ratio of the first duration and the second duration can be adjusted. For example, the ratio of the first duration and the second duration can be reduced with the progress of the bath process of the user, that is, the concentration of the ozone water gradually decreases, thereby preferably matching the use needs of the user.

[0226] In addition, by gradually reducing the ratio of the first duration and the second duration, it is beneficial to control the time for outputting ozone water, prevent excessive ozone water from contacting the user, and affect the safety of use.

[0227] In another specific embodiment, when the first duration and the second duration are fixed durations, the ratio of the first duration and the second duration is a preset ratio selectable by the user.

[0228] For the water supply device, a plurality of ratios of the first duration and the second duration can be stored. Different ratios of the first duration and the second duration correspond to ozone water with different concentrations. In the use process of the user, different preset ratios can be selected according to the current use needs, so as to obtain ozone water with a corresponding concentration to meet different use needs.

[0229] In another case, the control method can comprise:

[0230] If the user selects the second working mode and the water flow is greater than the first preset flow, a second current and / or a second voltage required by the ozone generation device 100 is determined according to the water flow and a second target ozone concentration in the second working mode;

[0231] The power supply module is controlled to apply the second current and / or the second voltage to the ozone generation device 100.

[0232] In the embodiment, the water supply device can store working parameters required by each working mode. The number of groups of the working parameters can be one or more. For example, in the second working mode, a corresponding relationship between the second target ozone concentration and the second current and / or the second voltage required by the ozone generation device 100 is stored. The corresponding relationship can be a continuously stored function relationship, a discontinuously stored table, or other forms, which are not limited in the present application.

[0233] When it is identified that the user currently selects the second working mode and the water flow through the ozone generation device 100 is greater than the first preset flow, a second current and / or a second voltage required to be applied to the ozone generation device 100 can be determined according to the current water flow and the target ozone concentration in the current mode. The current / voltage applied to the ozone generation device 100 is positively correlated with the water flow through the ozone generation device 100.

[0234] After the second current and / or the second voltage required to be applied to the ozone generation device 100 is determined, the power supply module is controlled to apply the second current and / or the second voltage to the ozone generation device 100, so as to form ozone water with the second target ozone concentration.

[0235] The working duration of the second working mode is less than or equal to a second preset duration.

[0236] For the case of working in the second working mode, the first electrode 11 in the ozone generation device 100 is a positive electrode and the second electrode 12 is a negative electrode, and ozone water is generated. After the ozone generation device 100 works for a duration, the polarity needs to be reversed to prevent scaling and ensure sustainable use of the ozone generation device 100. The second preset duration can be the maximum duration for which the first electrode 11 is a positive electrode and the second electrode 12 is a negative electrode in the ozone generation device 100. Specifically, the second preset duration can be 10 minutes, and the specific value of the second preset duration is not unique, which is not limited in the present application.

[0237] In yet another case, the water supply device further has a third working mode in which only the second state is executed; and the control method comprises:

[0238] In the third working mode, the working duration of the second working mode is obtained;

[0239] The working duration of the third working mode of the water supply device is greater than or equal to the working duration of the second working mode.

[0240] Since only the first state of generating ozone water is executed in the second working mode, the first electrode 11 continuously serves as an anode, the second electrode 12 continuously serves as a cathode, ozone is generated, and hydroxyl ions are continuously electrolyzed out during the generation of ozone, which easily form scale when combined with calcium and magnesium ions in water. In order to prolong the service life of the ozone generation device 100 and slow down the generation of scale, the third working mode can be executed to reverse the electrodes.

[0241] The working duration of the third working mode can be determined according to the working duration of the second working mode. Specifically, in order to neutralize the alkaline environment generated by the ozone generation device 100 in the second working mode in which only the first state is executed, the working duration of the third working mode of the water supply device is greater than or equal to the working duration of the second working mode.

[0242] It should be noted that in the description of the present application, the terms "first", "second" and the like are only used for descriptive purposes and to distinguish similar objects, and there is no prior or posterior order between them, nor can it be understood as indicating or implying relative importance. In addition, in the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more.
