DETAILED DESCRIPTION

[0040] In order to enable personnel in the technical field to better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0041] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0042] When water is electrolyzed, the anode product contains substances with strong oxidizing ability such as hydroxyl radicals and ozone, which can achieve disinfection and sterilization of the environment. Therefore, existing devices use electrolysis to achieve disinfection and sterilization of the environment. However, the electrolysis products at the cathode have reducing ability. When the anode product and the cathode product are output in a mixed flow, the anode product is consumed by the cathode product, and the disinfection and sterilization efficiency of the related device is reduced. If the anode product and the cathode product are output separately in a split flow, the cathode product is waste material for users in the application scenario of using the anode product for disinfection and sterilization, and users need to handle it, increasing the user's use burden. Therefore, how to ensure the related indicators of the output electrolysis product under the premise of reducing the user's use burden has become a problem to be solved.

[0043] In view of this, as shown in FIGS. 1-5, the utility model provides an oxidizing potential water generating module, which ensures the related indicators of the output electrolysis product under the premise of reducing the user's use burden.

[0044] Specifically, the oxidized potential water generating module comprises:

[0045] The electrolysis space 1 is provided with at least one anode 2 and at least one cathode 3;

[0046] The hydrogen outlet 4 is communicated with the electrolysis space 1 on the side of the cathode 3;

[0047] The electrolysis product outlet 5 is communicated with the electrolysis space 1 to output at least the electrolysis product in the electrolysis space 1 on the side of the anode 3.

[0048] The catalytic capacity of the anode 2 is greater than that of the cathode 3 in the utility model, and further, the anode 2 can adopt conductive diamond material to ensure the related indexes of the output electrolysis product.

[0049] With the hydrogen being discharged through the hydrogen outlet 4, the reduction of the electrolysis product on the side of the cathode 3 is weakened, and even if the electrolysis product here is mixed with the electrolysis product on the side of the anode 2 and is output, compared with the electrolysis product directly output in the form of mixed flow in the prior art, the utility model reduces the unnecessary consumption of the anode product, and therefore the related indexes of the output electrolysis product are still improved.

[0050] Since the hydrogen has reducing property, even if the hydrogen is generated, if the hydrogen is dissolved in the electrolysis product, a part of the anode product can still be consumed, based on this, in one embodiment of the utility model, as shown in Figures 1-2, in order to reduce the solubility of hydrogen in liquid, the solubility adjusting unit 6 is arranged at the cathode 3, for example, heating and stirring can reduce the solubility of hydrogen in liquid, the solubility adjusting unit 6 can be correspondingly arranged as a heating piece or a stirring piece, and the solubility adjusting unit 6 can also be arranged in the electrolysis space 1 on the side of the cathode 3.

[0051] Alternatively, in another embodiment of the utility model, in order to avoid the generated hydrogen directly contacting the anode product, the electrolysis space 1 can be divided into an anode chamber 7 and a cathode chamber 8, the anode chamber 7 and the cathode chamber 8 are communicated through an ion channel to realize the normal progress of the electrolysis process.

[0052] By arranging the cathode chamber 8 and the anode chamber 7, the possibility of reaction between hydrogen and the anode product can be reduced, and in order to further reduce the reaction possibility, the ion channel communicating the cathode chamber 8 and the anode chamber 7 can be arranged to mainly allow ions to pass, that is, the hydrogen generated at the cathode 3 cannot enter the anode chamber 7 through the ion channel, and the possibility of reaction between hydrogen and the anode product is further reduced.

[0053] For ion channel, it can be set as salt bridge, or ion exchange membrane 11, or the rest of the form, it should be clear that when the rest of the structural form can also achieve the function of avoiding the generated hydrogen gas directly contact with the anode product, the relevant structure also belongs to the protection scope of the utility model.

[0054] When the ion exchange membrane 11 is configured as a cation exchange membrane, the liquid inlet end 10 of the electrolysis space 1 is arranged on one side of the cathode chamber 8, and the raw liquid participating in electrolysis enters the electrolysis space 1 and participates in electrolysis at the cathode 3, and then the anion such as oxygen ion enters the anode chamber 7 through the ion exchange membrane 11 and participates in electrolysis at the anode 2, and water is generated in the process, so even if the liquid inlet end 10 is arranged on one side of the cathode chamber 8, the anode product in liquid state can still be realized in the anode chamber 7, but for the anode product generated at this time, since the water generated in the electrolysis process is needed to dissolve the generated product with sterilization function such as oxygen, a period of time needs to be waited at the initial stage of electrolysis, and when the water level in the anode chamber 7 reaches a certain level, the electrolysis product in the form of water flow or spray can be output for sterilization, but since the water is generated in the electrolysis process in the embodiment, the amount of water is small, so the concentration of the anode product in the output electrolysis product is high.

[0055] Or, in order to shorten the waiting time of the user, the ion exchange membrane 11 can be configured as a cation exchange membrane, at this time the liquid inlet end 10 of the electrolysis space 1 is arranged on one side of the anode chamber 7, and the raw liquid participating in electrolysis enters the electrolysis space 1 and participates in electrolysis at the anode 2, and then the cation such as hydrogen ion enters the cathode chamber 7 through the ion exchange membrane 11 and participates in electrolysis at the cathode 3, and the generated hydrogen gas is discharged through the hydrogen gas outlet 4, and in the embodiment, since the water inlet end 10 is arranged on one side of the anode chamber 7, the generation efficiency of the electrolysis product can be guaranteed.

[0056] Among them, the cation exchange membrane is preferably a proton exchange membrane that only allows hydrogen ions to pass through.

[0057] Further, the liquid inlet end 10 of the electrolysis space 1 in the utility model is of a variable cross-section structure, and the size of the liquid inlet end 10 increases along the direction close to the electrolysis space 1, so that the raw liquid entering the electrolysis space 1 through the liquid inlet end 10 is in a diffused state and can contact the anode 2 or the cathode 3 with a larger area, thereby improving the electrolysis efficiency.

[0058] Preferably, the axis of the liquid inlet end 10 is perpendicular to the cathode 3 or the anode 2, at this time the raw liquid entering the electrolysis space 1 through the liquid inlet end 10 will not have flow rate loss, directly contacts the cathode 3 or the anode 2, and participates in electrolysis.

[0059] The cathode 3 and the anode 2 are arranged on the two sides of the ion channel, that is, the cathode 3 and the anode 2 are arranged in the cathode chamber 8 and the anode chamber 7 respectively, and in the electrolysis process, the ions move to the cathode 3 and the anode 2 under the action of the power supply unit, therefore, if the distance between the cathode 3 and the anode 2 is far, a greater voltage is needed to ensure the normal electrolysis process, and in an embodiment of the utility model, preferably, at least one of the cathode 3 and the anode 2 is arranged at the end of the ion channel, so as to shorten the moving path of the ions and save energy.

[0060] More preferably, the cathode 3 and the anode 2 can be arranged at the end of the ion channel.

[0061] On the other hand, in order to increase the contact area of the cathode 3 or the anode 2 with the ions and improve the electrolysis efficiency, in an embodiment of the utility model, the cathode 3 is arranged perpendicularly to the moving direction of the ions entering the cathode chamber 8, at this time, the ions entering the cathode chamber 8 can contact the cathode 3 along the original moving direction, without flow rate loss, and the electrolysis efficiency is thus ensured.

[0062] Further, when the ion channel adopts the form of the ion exchange membrane 11, if the cathode 3 is arranged in close contact with the ion exchange membrane 11 to shorten the moving path of the ions, the ions needed to enter the anode chamber 7 cannot enter the anode chamber 7 under the blockage of the cathode 3 or need to bypass the cathode 3, and therefore the moving path of the ions is increased, therefore, at least one first through hole 9 is arranged at the cathode 2 which is perpendicular to the moving direction of the ions in the utility model, the first through hole 9 extends from one side close to the ion exchange membrane 11 to the opposite side, and the first through hole 9 shortens the moving path of the ions from the cathode chamber 8 to the anode chamber 7.

[0063] Alternatively, in another embodiment of the utility model, the anode 2 is arranged perpendicularly to the moving direction of the ions entering the anode chamber 7, so as to avoid flow rate loss of the ions entering the anode chamber 7, and further ensure the electrolysis efficiency.

[0064] Further, when the ion channel adopts the form of the ion exchange membrane 11, if the anode 2 is arranged in close contact with the ion exchange membrane 11 to shorten the moving path of the ions, the ions needed to enter the cathode chamber 8 cannot enter the cathode chamber 8 under the blockage of the anode 2 or need to bypass the anode 2, and therefore the moving path of the ions is increased, therefore, at least one first through hole 9 is arranged at the anode 3 which is perpendicular to the moving direction of the ions in the utility model, the first through hole 8 extends from one side close to the ion exchange membrane 11 to the opposite side.

[0065] In one embodiment of the utility model, considering that the ion channel adopts the form of ion exchange membrane 11, due to the characteristics of ion exchange membrane 11, even if the liquid inlet end 10 is arranged on the side of anode chamber 7, the generated hydrogen gas will inevitably carry some water vapor, and when the water vapor meets the inner wall of cathode chamber 8, which is a structure with relatively low temperature, it will condense into water droplets, and when the hydrogen gas is discharged to the outside through hydrogen gas outlet 4, water droplets will inevitably be generated, although the amount of water in the water droplets does not need to be handled by the user in the form of shunt output, the generation of water droplets will still reduce the user's experience.

[0066] Based on this, the utility model discloses that hydrogen gas outlet 4 and electrolytic space 1 are also provided with gas-liquid separation unit 12, specifically, gas-liquid separation unit 12 is arranged between hydrogen gas outlet 4 and cathode chamber 8, gas-liquid separation unit 12 is used to promote the condensation of water vapor carried by hydrogen gas on one hand, and is used to separate the water droplets condensed into liquid from hydrogen gas on the other hand, hydrogen gas is discharged through hydrogen gas outlet 31, since hydrogen gas can directly diffuse in the external environment, the user does not need to handle additionally, reducing the user's use burden, liquid can be intercepted in cathode chamber 8 of electrolytic space 1, or since liquid has been separated from hydrogen gas, the consumption of anode product is reduced, therefore from the angle of saving water, this part of liquid can also be output to the liquid outlet path of anode product or the liquid inlet path of electrolytic space 1.

[0067] Gas-liquid separation unit 11 can distinguish hydrogen gas and liquid by density, but this separation method has some limitations in use, for example, when the output device of the oxidation potential water generation module is placed vertically, hydrogen gas outlet 4 is arranged upward, hydrogen gas can diffuse to the external environment through hydrogen gas outlet 4, but when the user uses the output device obliquely or upside down, with the upside-down, hydrogen gas outlet 4 is located below, and at this time, hydrogen gas outlet 4 discharges water droplets formed by condensation.

[0068] Based on this, the utility model discloses that gas-liquid separation unit 11 adopts the form of waterproof air-permeable piece, such as polytetrafluoroethylene, by using the characteristics of waterproof air-permeable piece, air-permeable and water-impermeable, with the continuous electrolysis process, hydrogen gas in cathode chamber 8 is continuously discharged through hydrogen gas outlet 4.

[0069] On the other hand, since hydrogen gas is discharged, liquid in cathode chamber 8 can be discharged to the liquid outlet path of electrolytic product or the liquid inlet path of electrolytic space, at this time, the related indicators of the output electrolytic product are still improved.

[0070] Alternatively, this portion of liquid can be retained in the cathode chamber 8. When the cathode chamber 8 is full of liquid, hydrogen will still be continuously discharged from the hydrogen outlet 4, and the electrolysis process can still proceed normally. At this time, most of the raw liquid that enters the electrolysis space 1 through the liquid inlet 10 participates in the electrolysis reaction at the anode 2. The conversion rate between the raw liquid and the desired electrolysis products is high, and the output of the desired electrolysis products is increased.

[0071] In this invention, under the same electrolysis conditions, when the anode 2 is made of ruthenium-iridium material, the redox potential of the electrolysis product output in the mixed-flow form of the prior art is only 530mV. If the electrolysis space 1 with the hydrogen outlet 4 located on one side of the cathode 3 is used in the present invention, the redox potential of the output electrolysis product can be increased to 680mV. When the structure of the cathode chamber 8 and the anode chamber 7 are separated by the ion exchange membrane 11 in the present invention, the redox potential of the output electrolysis product can be increased to 830mV under the action of hydrogen discharge.

[0072] When the anode 2 is made of conductive diamond, compared with the existing technology that outputs electrolytic products in the form of mixed flow, this utility model can increase the redox potential of the output electrolytic products from 760mV to 950mV by setting hydrogen outlet 4.

[0073] This utility model also provides an output device using the above-mentioned oxidation potential water generation module. Since this utility model improves the relevant indicators of the output electrolytic products, the output device of this utility model can be used for environmental disinfection. In subsequent research, when the output device using electrolytic products is applied to other life scenarios, the relevant output device should also fall within the protection scope of this utility model.

[0074] Specifically, the output device of this utility model includes a housing and an oxidation potential water generating module. The oxidation potential water generating module adopts the above-mentioned oxidation potential water generating module and can be set on the outside of the housing or inside the housing. In this case, the housing protects the oxidation potential water generating module.

[0075] Since the oxidized electrolyzed water generation module is equipped with a hydrogen outlet 4, the hydrogen can be discharged into the housing or discharged into the outside through the exhaust port on the housing that connects to the outside, thus diffusing into the air. Users do not need to perform any additional treatment on it.

[0076] Alternatively, considering that some output devices output electrolysis products in the form of spraying, the hydrogen gas discharged by the oxidation potential water generating module of the present application can also be directly sucked by the air pump to participate in spraying. In this case, although the hydrogen gas is in contact with the anode products again, the hydrogen gas is diffused in the air in the shell and then sucked by the air pump to participate in spraying. Therefore, the hydrogen gas diluted by the air has less impact on the related indicators of the anode products. Even if the hydrogen gas is used to participate in spraying, the related indicators of the electrolysis products output by the output device of the present application are still improved compared with the related indicators of the anode products output in the mixed flow state in the prior art.

[0077] The above merely describes the preferred embodiments of the present application, and it should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
