Description

Technical Field

[0001] This application belongs to the field of water electrolysis technology, specifically relating to an oxidation potential water generation module and output device. Background Technology

[0002] When water is electrolyzed, the electrolysis products at the anode include hydroxyl radicals with strong oxidizing power, ozone, and oxygen. Therefore, the anode products are often used to disinfect and sterilize the environment.

[0003] However, since the electrolysis products at the cathode have reducing power, when the cathode and anode products are output in a mixed flow, a reaction will occur between the anode and cathode products, meaning that the anode products may be consumed. As a result, the efficiency of the related equipment for disinfection and sterilization is reduced. If the cathode and anode products are output separately in a split flow, in applications where the anode products are used for disinfection and sterilization, the output cathode products are considered waste. In this case, the cathode products need to be processed by the user, which increases the user's burden.

[0004] Therefore, in order to ensure the disinfection efficiency of the relevant equipment, how to guarantee the relevant indicators of the anode products while reducing the burden on users has become an urgent problem to be solved. Utility Model Content

[0005] One objective of this invention is to overcome the shortcomings of the prior art and provide an oxidation potential water generation module that can reduce the user's burden while ensuring the relevant indicators of the output electrolytic products.

[0006] Another objective of this invention is to provide an output device that uses the above-mentioned oxidized electrolyzed water generation module.

[0007] To achieve the primary objective, this utility model adopts the following technical solution:

[0008] An oxidation potential water generation module, comprising:

[0009] The electrolysis space is equipped with at least one anode and at least one cathode;

[0010] The hydrogen outlet is connected to the electrolysis space on one side of the cathode;

[0011] The electrolysis product outlet is connected to the electrolysis space to output at least the electrolysis products from the electrolysis space on the anode side.

[0012] Furthermore, a solubility adjustment unit is provided at the cathode or in the electrolysis space on one side of the cathode to reduce the solubility of hydrogen in the liquid.

[0013] Furthermore, the electrolysis space includes a cathode chamber and an anode chamber, which are connected by an ion channel, and the anode chamber is connected to the electrolysis product outlet;

[0014] The cathode and anode are respectively disposed on both sides of the ion channel.

[0015] Furthermore, the cathode and / or the anode are disposed at the end of the ion channel.

[0016] Furthermore, the cathode is positioned perpendicular to the direction of movement of the ions entering the cathode chamber;

[0017] And / or, the anode is positioned perpendicular to the direction of movement of ions entering the anode chamber.

[0018] Furthermore, at least one first through hole is provided at the cathode and / or the anode perpendicular to the direction of ion movement, the first through hole extending from one side near the ion channel to the opposite side.

[0019] Furthermore, the ion channel is configured as a cation exchange membrane, and the liquid inlet end of the electrolysis space is located on one side of the anode chamber.

[0020] Furthermore, the liquid inlet end has a variable cross-section structure, and the size of the liquid inlet end increases along the direction close to the electrolysis space.

[0021] Furthermore, the axis of the liquid inlet is perpendicular to the anode.

[0022] Furthermore, a gas-liquid separation unit is provided between the hydrogen outlet and the electrolysis space. The hydrogen in the electrolysis product on the cathode side is discharged through the hydrogen outlet, while the liquid is retained in the electrolysis space or discharged to the liquid outlet path of the electrolysis product or the liquid inlet path of the electrolysis space.

[0023] To achieve the second objective, the present invention adopts the following technical solution:

[0024] An output device characterized by employing the aforementioned oxidized potential water generation module.

[0025] Furthermore, it also includes a housing, and the oxidation potential water generating module is disposed inside the housing;

[0026] The housing is provided with an exhaust port that communicates with the outside, and the exhaust port is connected to the hydrogen outlet of the oxidation potential water generation module.

[0027] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0028] 1. This invention outputs the generated electrolytic products and hydrogen separately. The hydrogen can diffuse directly into the external environment without the need for additional processing by the user. Even if the cathode product separated from the hydrogen is transported back to the outlet path of the anode product and mixed with the anode product for output, it will not consume too much of the anode product. Therefore, this invention fully guarantees the output of electrolytic products with high oxidation-reduction potential while reducing the user's burden.

[0029] 2. Since the hydrogen gas discharged through the hydrogen outlet carries some water vapor, this water vapor will condense into water droplets when it is cooled, which will affect the user experience. The oxidized potential water generation module of this utility model is equipped with a gas-liquid separation unit, which promotes the condensation of water vapor and separates water droplets from hydrogen gas, so that only hydrogen gas is discharged, thus avoiding a reduction in the user experience.

[0030] 3. In this invention, when a cation exchange membrane is provided, the raw solution that enters the electrolysis space to participate in electrolysis participates in electrolysis at the anode chamber, and the cathode product is hydrogen gas. Therefore, the conversion rate between the raw solution and the desired electrolysis product is relatively high. Attached Figure Description

[0040] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0041] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0042] When water is electrolyzed, the anode products contain substances with strong oxidizing capabilities, such as hydroxyl radicals and ozone, which can disinfect and sterilize the environment. Therefore, existing equipment utilizes the electrolysis principle for environmental disinfection. However, because the electrolysis products at the cathode have reducing capabilities, when the anode and cathode products are output in a mixed-flow manner, the anode product may be consumed by the cathode product, thus reducing the disinfection efficiency of the equipment. If the anode and cathode products are output separately, in applications using anode products for disinfection, the cathode product becomes waste for the user, requiring further treatment and increasing the user's burden. Therefore, how to ensure the relevant indicators of the output electrolysis products while reducing the user's burden has become an urgent problem to be solved.

[0043] In view of this, such as Figure 1-5 As shown, this utility model provides an oxidation potential water generation module that ensures the relevant indicators of the output electrolytic products while reducing the user's burden.

[0044] Specifically, the oxidized potential water generation module of this utility model includes:

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

[0046] Hydrogen outlet 4 is connected to the electrolysis space 1 on one side of cathode 3;

[0047] Electrolysis product outlet 5 is connected to electrolysis space 1 to output at least the electrolysis products in electrolysis space 1 on the anode 3 side.

[0048] In this invention, the catalytic capacity of the anode 2 is greater than that of the cathode 3. Furthermore, the anode 2 can be made of conductive diamond material to ensure the relevant indicators of the output electrolytic products.

[0049] As hydrogen is discharged through hydrogen outlet 4, the reducing power of the electrolytic products on the cathode 3 side is reduced. Even if the electrolytic products here are mixed with the electrolytic products on the anode 2 side for output, compared with the electrolytic products that are directly output in mixed flow form in the prior art, the present invention reduces the unnecessary consumption of anode products, so the relevant indicators of the output electrolytic products are still improved.

[0050] Because hydrogen has reducing properties, even if hydrogen is generated, if a significant amount of hydrogen dissolves in the electrolysis products, it may still consume a portion of the anode products. Therefore, in one embodiment of this invention, such as... Figure 1-2 As shown, in order to reduce the solubility of hydrogen in the liquid, a solubility adjustment unit 6 is provided at the cathode 3. For example, heating and stirring can reduce the solubility of hydrogen in the liquid. The solubility adjustment unit 6 can be set as a heating element or a stirring element accordingly. The solubility adjustment unit 6 can also be set in the electrolysis space 1 on one side of the cathode 3.

[0051] Alternatively, in another embodiment of this utility model, in order to avoid the generated hydrogen gas from directly contacting the anode product, the electrolysis space 1 can be divided into an anode chamber 7 and a cathode chamber 8, which are connected by an ion channel to enable the normal operation of the electrolysis process.

[0052] By setting up a cathode chamber 8 and an anode chamber 7, the possibility of hydrogen reacting with the anode products can be reduced. To further reduce the possibility of reaction, the ion channel connecting the cathode chamber 8 and the anode chamber 7 can be set to allow ions to pass through, that is, hydrogen generated at the cathode 3 cannot enter the anode chamber 7 through the ion channel, which further reduces the possibility of hydrogen reacting with the anode products.

[0053] For ion channels, they can be set as salt bridges, ion exchange membranes 11, or other forms. It should be clear that when the function of preventing the generated hydrogen from directly contacting the anode products can also be achieved through other structural forms, the relevant structural forms should also fall within the protection scope of this utility model.

[0054] When the ion exchange membrane 11 is configured as an anion exchange membrane, the liquid inlet 10 of the electrolysis space 1 is located on one side of the cathode chamber 8. After the raw solution participating in the electrolysis enters the electrolysis space 1, it participates in electrolysis at the cathode 3. Then, anions such as oxygen ions enter the anode chamber 7 through the ion exchange membrane 11 and participate in electrolysis at the anode 2. Water is generated during this process. Therefore, even if the liquid inlet 10 is only located on one side of the cathode chamber 8, the anode product can still be in liquid state in the anode chamber 7. However, for the anode product generated at this time, since the water generated during the electrolysis process is needed to dissolve the bactericidal products such as oxygen, it is necessary to wait for a period of time in the early stage of electrolysis. Only when the water level in the anode chamber 7 reaches a certain level can the electrolysis product in the form of water flow or spray be output for disinfection. However, since the water is generated during the electrolysis process in this embodiment, that is, the amount of water is small, the concentration of anode product in the output electrolysis product is high.

[0055] Alternatively, to shorten the user's waiting time, the ion exchange membrane 11 can be configured as a cation exchange membrane. In this case, the liquid inlet 10 of the electrolysis space 1 is located on one side of the anode chamber 7. After the raw liquid participating in the electrolysis enters the electrolysis space 1, it participates in electrolysis at the anode 2. Then, hydrogen ions and other cations enter the cathode chamber 7 through the ion exchange membrane 11 and participate in electrolysis at the cathode 3. The generated hydrogen gas is discharged through the hydrogen outlet 4. In this embodiment, since the liquid inlet 10 is located on one side of the anode chamber 7, the generation efficiency of the electrolysis products can be guaranteed.

[0056] The cation exchange membrane is preferably a proton exchange membrane that allows only hydrogen ions to pass through.

[0057] Furthermore, in this invention, the liquid inlet end 10 of the electrolysis space 1 has a variable cross-section structure. Along the direction close to the electrolysis space 1, the size of the liquid inlet end 10 increases. When the raw liquid enters the electrolysis space 1 through the liquid inlet end 10, it diffuses and can contact the anode 2 or cathode 3 with a larger area, thereby improving the electrolysis efficiency.

[0058] Preferably, the axis of the liquid inlet 10 is perpendicular to the cathode 3 or the anode 2. In this case, the raw liquid entering the electrolysis space 1 through the liquid inlet 10 will not have a flow rate loss and will directly contact the cathode 3 or the anode 2 to participate in electrolysis.

[0059] In this invention, the cathode 3 and anode 2 are respectively disposed on both sides of the ion channel, that is, the cathode 3 and anode 2 are respectively disposed in the cathode chamber 8 and the anode chamber 7. During the electrolysis process, under the action of the power supply unit, the ions move towards the cathode 3 and the anode 2 respectively. Therefore, if the cathode 3 and anode 2 are far apart, a larger voltage is required to ensure the normal operation of the electrolysis process. In one embodiment of this invention, it is preferable to place at least one of the cathode 3 and anode 2 at the end of the ion channel to shorten the movement path of the ions and save energy.

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

[0061] On the other hand, in order to increase the contact area between the cathode 3 or anode 2 and the ions and improve the electrolysis efficiency, in one embodiment of the present invention, the cathode 3 is set perpendicular to the movement 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 movement direction without any flow rate loss, thus ensuring the electrolysis efficiency.

[0062] Furthermore, when the ion channel is in the form of an ion exchange membrane 11, if the cathode 3 is attached to the ion exchange membrane 11 to shorten the ion movement path, ions that need to enter the anode chamber 7 cannot enter the anode chamber 7 due to the obstruction of the cathode 3 or need to bypass the cathode 3, thus increasing the ion movement path. Therefore, in this invention, at least one first through hole 9 needs to be provided at the cathode 2 perpendicular to the ion movement direction. The first through hole 9 extends from the side near the ion exchange membrane 11 to the opposite side, and the first through hole 9 shortens the movement path of ions from the cathode chamber 8 to the anode chamber 7.

[0063] Alternatively, in another embodiment of this invention, the anode 2 is arranged perpendicular to the direction of movement of ions entering the anode chamber 7, so as to avoid flow rate loss of ions entering the anode chamber 7, thereby ensuring electrolysis efficiency.

[0064] Furthermore, when the ion channel is in the form of an ion exchange membrane 11, if the anode 2 is attached to the ion exchange membrane 11 to shorten the ion movement path, the ions that need to enter the cathode chamber 8 cannot enter the cathode chamber 8 due to the obstruction of the anode 2 or need to bypass the anode 2, thus increasing the ion movement path. Therefore, in this invention, at least one first through hole 9 needs to be provided at the anode 3 perpendicular to the ion movement direction. The first through hole 9 extends from the side near the ion exchange membrane 11 to the opposite side.

[0065] In one embodiment of this utility model, considering that the ion channel is in the form of an ion exchange membrane 11, due to the characteristics of the ion exchange membrane 11, even if the liquid inlet 10 is located on the side of the anode chamber 7, the generated hydrogen will inevitably carry some water vapor. When this water vapor encounters the relatively low-temperature structure such as the inner wall of the cathode chamber 8, it will condense into water droplets. When the hydrogen is discharged to the outside through the hydrogen outlet 4, the water vapor will inevitably generate water droplets. Although the amount of water droplets does not require the user to perform additional processing on the cathode products as in the form of split output, the generation of water droplets will still reduce the user's experience.

[0066] Based on this, a gas-liquid separation unit 12 is also provided between the hydrogen outlet 4 and the electrolysis space 1 in this utility model. Specifically, the gas-liquid separation unit 12 is located between the hydrogen outlet 4 and the cathode chamber 8. The gas-liquid separation unit 12 is used to promote the condensation of water vapor carried by hydrogen and to separate the condensed water droplets from the hydrogen. The hydrogen is discharged through the hydrogen outlet 31. Since the hydrogen can diffuse directly into the external environment, no additional treatment is required by the user, reducing the user's burden. The liquid can be trapped in the cathode chamber 8 of the electrolysis space 1, or since the liquid has been separated from the hydrogen, the consumption of anode products is reduced. Therefore, from the perspective of water saving, this part of the liquid can also be output to the liquid outlet path of the anode products or the liquid inlet path of the electrolysis space 1.

[0067] The gas-liquid separation unit 11 can distinguish hydrogen from liquid by density, but this separation method is limited by the angle of use. For example, when the output device of the oxidation potential water generation module is upright, the hydrogen outlet 4 is set upward, and hydrogen can diffuse into the external environment through the hydrogen outlet 4. However, when the user tilts or inverts the relevant output device, the hydrogen outlet 4 is located at the bottom as it is upside down. At this time, the hydrogen outlet 4 discharges water droplets formed by condensation.

[0068] Based on this, the gas-liquid separation unit 11 of this utility model adopts a waterproof and breathable component, such as polytetrafluoroethylene. Utilizing the breathable and waterproof characteristics of the component, as the electrolysis process continues, the hydrogen gas in the cathode chamber 8 is continuously discharged through the hydrogen outlet 4.

[0069] On the other hand, since hydrogen is discharged, the liquid in the cathode chamber 8 can be discharged to the liquid outlet path of the electrolysis products or the liquid inlet path of the electrolysis space. At this time, the relevant indicators of the output electrolysis products 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 electrolytic products in the form of spray, the hydrogen gas discharged from the oxidation potential water generation module of this invention can also be directly drawn into the spray by the air pump. In this case, although the hydrogen gas re-contacts the anode product, since the hydrogen gas diffuses into the air inside the shell and is then drawn into the spray by the air pump, the hydrogen gas diluted by the air has a smaller impact on the relevant indicators of the anode product. That is, even if hydrogen gas is used to participate in the spray, the relevant indicators of the electrolytic products output by the output device of this invention are still improved compared with the relevant indicators of the anode products output in the mixed flow state in the prior art.

[0077] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
