Description

Technical Field

[0001] This utility model relates to the field of electrolysis, and in particular to a water electrolysis device, a humidifier, and an air treatment equipment. Background Technology

[0002] Electrocatalysis, with its advantages of clean and inexpensive electricity, has been widely applied in academia for research on the catalytic synthesis of high-value-added compounds, fuel cells, and hydrogen production. In industry, electrocatalysis is also commonly used in water treatment, such as wastewater purification, dye degradation, and sterilization.

[0003] However, during electrocatalysis, insoluble solids often form on the cathode surface due to chemical reactions or physical deposition, a phenomenon known as scaling. Scale layers typically have high resistance, increasing the internal resistance of the electrode, leading to increased energy loss and reduced energy efficiency in the electrocatalytic process. Scaling can also cause corrosion and damage to electrode materials, shortening the lifespan of the electrocatalytic equipment and increasing maintenance and replacement costs. Furthermore, the formation of scale may be uneven, resulting in uneven current distribution during the electrocatalytic process, causing operational instability and affecting product quality and yield.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] The following is for reference. Figures 1-5 Describes an electrolytic water apparatus 100 according to an embodiment of the present invention.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The water electrolysis device 100 according to an embodiment of this utility model includes: a proton exchange membrane 1, an anode electrode plate 2, and a cathode electrode plate 3, which are disposed on both sides of the proton exchange membrane 1. When an external power source is applied to the anode electrode plate 2 and the cathode electrode plate 3, water molecules can undergo an oxidation reaction on the anode electrode plate 2. Under the action of the anode catalyst, the water molecules lose electrons to generate oxygen and protons. Electrons flow through the anode electrode plate 2 to the positive electrode of the external power source. The generated protons are conducted from the anode side to the cathode side through the proton exchange membrane 1. The proton exchange membrane 1 ensures that only protons can pass through, maintaining the selectivity of the reaction and the orderliness of ion transport. On the cathode electrode plate 3, electrons flowing from the negative electrode of the external power source undergo a reduction reaction with the protons conducted through the proton exchange membrane 1. The protons gain electrons to generate hydrogen gas, thereby producing hydrogen gas at the cathode and oxygen gas at the anode, realizing the conversion of electrical energy into chemical energy and achieving the purpose of producing hydrogen and oxygen gas by electrolyzing water.

[0038] It should be noted that the above reactions are the basic chemical reactions of the water electrolysis device 100. When the water electrolysis device 100 electrolyzes liquids, some other side reactions or reactions related to specific conditions may also occur, such as chlorine evolution reaction, reduction reaction of organic matter, acid-base neutralization reaction, etc. This utility model does not limit these reactions.

[0039] The water electrolysis device 100 further includes an isolation layer 4 and a first conductive component 5. A portion of the surface of the cathode electrode 3 is in contact with the proton exchange membrane 1, and the isolation layer 4 covers the remaining portion of the surface of the cathode electrode 3. The first conductive component 5 passes through the isolation layer 4 and is electrically connected to the cathode electrode 3. The first conductive component 5 and the anode electrode 2 are adapted to be connected to an external power source.

[0040] The first conductive component 5 passes through the isolation layer 4 and is conductively connected to the cathode electrode 3, so that the cathode electrode 3 can be connected to an external power source through the first conductive component 5, ensuring the reliability of the operation of the water electrolysis device 100.

[0041] According to the electrolytic water device 100 of this utility model embodiment, the isolation layer 4 covers the remaining part of the surface of the cathode electrode plate 3 and occupies the space on the surface of the cathode electrode plate 3, making it difficult for the substances generated by electrolysis (such as compounds containing metal ions such as calcium and magnesium) to directly contact the surface of the cathode electrode plate 3, thereby reducing the chance of these substances depositing on the cathode electrode plate 3 and effectively improving the problem of scaling on the cathode electrode plate 3.

[0042] In some embodiments, the isolation layer 4 is a resin material component.

[0043] Resin materials typically possess good chemical inertness, preventing chemical reactions with electrolyte components and avoiding impurities or byproducts arising from such reactions. This ensures the stability and purity of the electrode reaction, contributing to improved efficiency and product quality during electrolysis. Resin materials also exhibit excellent molding properties, allowing for the easy fabrication of various shapes and thicknesses of insulating layers 4 through diverse processing methods such as coating, spraying, molding, and injection molding, tailored to different electrode shapes and sizes. These layers adhere well to the electrode surface, achieving precise isolation. Furthermore, resin materials are generally low in cost, and their processing technology is relatively simple and efficient, further reducing the manufacturing cost of the insulating layer 4.

[0044] In some embodiments, the isolation layer 4 is a hydrophilic material. For example, the isolation layer 4 can be a material such as polyvinyl alcohol, polyethylene glycol, or hydrogel.

[0045] In this embodiment of the invention, the isolation layer 4 with suitable hydrophilicity allows the electrolyte to form a uniform liquid film on its surface, reducing local concentration polarization and preventing scale-forming substances from excessively concentrating and crystallizing in local areas. This further reduces the possibility of scaling.

[0046] In some embodiments, the isolation layer 4 is a hydrophobic material. For example, the isolation layer 4 can be made of materials such as polytetrafluoroethylene, silicone rubber, fluororubber, or polyimide.

[0047] In this embodiment of the invention, the hydrophobic isolation layer 4 can reduce the adhesion of water and solute in the electrolyte to its surface, making it less likely for scale-forming substances to remain and accumulate on it, thereby reducing the possibility of scaling.

[0048] In some specific embodiments, the cathode electrode 3 has a rectangular sheet structure, with the larger rectangular surface of the cathode electrode 3 in contact with the proton exchange membrane 1, and the other five surfaces of the cathode electrode 3 in contact with the isolation layer 4.

[0049] In this embodiment of the invention, the structure of the cathode electrode 3 and the structure of the isolation layer 4 are simple, which reduces the cost of the water electrolysis device 100.

[0050] In some embodiments, the water electrolysis device 100 further includes an anode conductive sheet 6, which is disposed on the side of the anode electrode 2 away from the proton exchange membrane 1. The anode conductive sheet 6 contacts the anode electrode 2 to support and electrically connect the anode electrode 2, and the anode conductive sheet 6 is adapted to be electrically connected to an external power source.

[0051] When the water electrolysis device 100 is in operation, both the first conductive component 5 and the anode conductive plate 6 are electrically connected to an external power source, thereby connecting the cathode electrode plate 3 and the anode electrode plate 2 to the circuit for liquid electrolysis. In this embodiment of the invention, the anode conductive plate 6 not only conducts electricity but also supports the anode electrode plate 2, providing mechanical support to maintain its stable shape and position and preventing deformation or damage during operation. Simultaneously, it also protects the anode electrode plate 2 from external environmental corrosion to a certain extent, extending its service life.

[0052] In some embodiments, the anode conductive sheet 6 is provided with a through hole 61 for gas to escape.

[0053] When the water electrolysis device 100 is working, an oxidation reaction can occur at the anode electrode plate 2 to generate gas. This gas can be oxygen, ozone, or other gases, and this invention does not limit this. Because an anode conductive plate 6 is provided on the side of the anode electrode plate 2 away from the proton exchange membrane 1, occupying the space on the surface of the anode electrode plate 2, the gas generated on the surface of the anode electrode plate 2 is difficult to escape, resulting in an increase in the concentration of reaction products on the surface of the anode electrode plate 2, thereby affecting the reaction rate and causing a decrease in the generation rate of the required reaction products, thus affecting the working efficiency of the water electrolysis module. In this embodiment of the invention, by providing a through hole 61 on the anode conductive plate 6, the gas generated on the surface of the anode electrode plate 2 can escape through the through hole 61, reducing the concentration of reaction products on the surface of the anode electrode plate 2, which is beneficial to improving the working efficiency of the water electrolysis module.

[0054] In some specific embodiments, the cathode electrode 3, proton exchange membrane 1, anode electrode 2, and anode conductive sheet 6 have the same shape and the same size.

[0055] The identical shape and size make the installation of components in the water electrolysis device 100 more convenient and faster during assembly, facilitating automated production, improving production efficiency and product consistency, reducing assembly difficulty, and increasing production speed and product quality. Furthermore, the identical shape and size ensure uniform contact area between the cathode electrode 3, anode electrode 2, and proton exchange membrane 1, allowing the electrochemical reaction to proceed evenly across the entire electrode surface, preventing excessively strong or weak local reactions, and improving the overall performance and stability of the water electrolysis device 100.

[0056] It should be noted that the thicknesses of the cathode electrode 3, proton exchange membrane 1, anode electrode 2, and anode conductive sheet 6 can be the same or different, and this utility model does not impose any restrictions on this.

[0057] In some embodiments, the water electrolysis device 100 further includes a connector 7, which is an insulating material component. The connector 7 connects the proton exchange membrane 1, the anode electrode plate 2, the anode conductive plate 6, the cathode electrode plate 3, and the isolation layer 4 into a module.

[0058] Through the above technical solution, the isolation layer 4, cathode electrode plate 3, proton exchange membrane 1, anode electrode plate 2 and anode conductive plate 6 are connected into a module, which facilitates the assembly of the module and further improves the assembly efficiency of the water electrolysis device 100.

[0059] In some specific embodiments, the connector 7 can be insulating tape, which binds the insulating layer 4, the cathode electrode 3, the proton exchange membrane 1, the anode electrode 2, and the anode conductive sheet 6 together.

[0060] In some other embodiments, the connector 7 may also be an insulating clip, which fixes the isolation layer 4, cathode electrode 3, proton exchange membrane 1, anode electrode 2 and anode conductive sheet 6 together.

[0061] In some other specific embodiments, the connector 7 may also be an insulated bolt and nut, with the bolt passing through the isolation layer 4, the cathode electrode plate 3, the proton exchange membrane 1, the anode electrode plate 2, and the anode conductive plate 6 and connected to the nut.

[0062] In other embodiments, the connector 7 may also have other structures, and this invention does not limit this.

[0063] In some embodiments, the water electrolysis device 100 further includes: a housing 8, which is provided with a flow channel for liquid to pass through, and a proton exchange membrane 1, an anode electrode plate 2, a cathode electrode plate 3 and an isolation layer 4 are all located inside the housing 8 for electrolyzing the liquid in the flow channel.

[0064] In other words, the water electrolysis device 100 in this embodiment is a flow-through water electrolysis device 100. The flow-through design allows the electrolyte to flow rapidly within the flow channel, enabling reactants to be continuously transported to the electrode surface while products are promptly carried away. This significantly improves mass transfer efficiency, reduces concentration polarization of reactants on the electrode surface, and thus increases the rate of electrolysis, achieving higher gas production efficiency and generating more hydrogen, oxygen, ozone, or other gases per unit time. Furthermore, the flow of the electrolyte can flush the electrode surface, preventing the deposition of impurities and products on the electrodes, further improving the scaling problem on the cathode electrode plate 3.

[0065] It should be understood that the water electrolysis device 100 can also be an immersion type water electrolysis device 100, and this utility model does not limit it in this way.

[0066] In some embodiments, the first conductive component 5 passes through the housing 8 and is partially located outside the housing 8 to be electrically connected to an external power source; the water electrolysis device 100 further includes a second conductive component 9 electrically connected to the anode electrode plate 2, the second conductive component 9 passing through the housing 8 and being partially located outside the housing 8 to be electrically connected to an external power source.

[0067] The above technical solution allows the first conductive component 5 to be located on the outside of the housing 8 and the second conductive component 9 to be located on the outside of the housing 8, so that the first conductive component 5 and the second conductive component 9 can be electrically connected to an external power source, thereby improving the ease of use of the water electrolysis device 100.

[0068] In some embodiments, the first conductive component 5 includes a first conductive post 51, which passes through the housing 8 and the isolation layer 4 and is conductively connected to the cathode electrode sheet 3. The first conductive post 51 is fixed relative to the housing 8 and supports the cathode electrode sheet 3.

[0069] In this embodiment of the present invention, the first conductive post 51 can not only conduct electricity to the cathode electrode plate 3, but also support the cathode electrode plate 3, thereby improving the stability of the structure of the isolation layer 4, the cathode electrode plate 3, the proton exchange membrane 1, the anode electrode plate 2, and the anode conductive plate 6, and improving the reliability of the water electrolysis device 100.

[0070] It should be noted that the first conductive post 51 and the housing 8 can be connected by interference fit, snap-fit, adhesive, screw connection or other means, and this utility model does not limit this.

[0071] In some further embodiments, multiple first conductive pillars 51 are provided to support the cathode electrode sheet 3, thereby further improving the stability of the structure including the isolation layer 4, the cathode electrode sheet 3, the proton exchange membrane 1, the anode electrode sheet 2, and the anode conductive sheet 6.

[0072] In some embodiments, the first conductive component 5 further includes a cathode conductive metal sheet 52 adapted to be connected to an external power source. The cathode conductive metal sheet 52 is connected to the first conductive post 51 and is fixed to the housing 8.

[0073] The first conductive post 51 has a columnar structure, which is not convenient to connect directly to an external power source. In this embodiment of the present invention, the first conductive post 51 is connected to the cathode conductive metal sheet 52, which is suitable for connection to an external power source, thereby improving the ease of use of the water electrolysis device 100.

[0074] In some embodiments, the first conductive component 5 further includes a first conductive nut 53, which is threadedly connected to the first conductive post 51, and a portion of the cathode conductive metal sheet 52 is sandwiched between the first conductive nut 53 and the housing 8 to be fixed to the housing 8.

[0075] In this embodiment of the invention, the first conductive nut 53 not only enables the conductive connection between the first conductive post 51 and the cathode conductive metal sheet 52, but also fixes the cathode conductive metal sheet 52, thereby improving the assembly efficiency of the water electrolysis module.

[0076] In some specific embodiments, two first conductive posts 51 are provided, and the cathode conductive metal sheet 52 is elongated and electrically connected to the two first conductive posts 51 respectively. Each of the two first conductive posts 51 is provided with a first conductive nut 53 for fixing the cathode conductive metal sheet 52.

[0077] The above technical solution further improves the stability of the connection between the cathode conductive metal sheet 52 and the housing 8, as well as the reliability of the cathode conductive metal sheet 52's conductivity.

[0078] In some embodiments, the second conductive component 9 includes a second conductive post 91, which passes through the housing 8 and is conductively connected to the anode electrode plate 2. The second conductive post 91 is fixed relative to the housing 8 and supports the anode electrode plate 2.

[0079] In this embodiment of the present invention, the second conductive post 91 can not only conduct electricity to the anode electrode plate 2, but also support the anode electrode plate 2, thereby improving the stability of the isolation layer 4, cathode electrode plate 3, proton exchange membrane 1, anode electrode plate 2 and anode conductive plate 6, and improving the reliability of the water electrolysis device 100.

[0080] It should be noted that the second conductive post 91 and the housing 8 can be connected by interference fit, snap-fit, adhesive, screw connection or other means, and this utility model does not limit this.

[0081] In some further embodiments, multiple second conductive posts 91 are provided to support the anode electrode sheet 2, thereby further improving the stability of the structures such as the isolation layer 4, cathode electrode sheet 3, proton exchange membrane 1, anode electrode sheet 2, and anode conductive sheet 6.

[0082] In some embodiments, the second conductive component 9 further includes an anode conductive metal sheet 92 adapted to be connected to an external power source, the anode conductive metal sheet 92 being connected to the second conductive post 91, and the anode conductive metal sheet 92 being fixed to the housing 8.

[0083] The second conductive post 91 has a columnar structure, which is not convenient to connect directly to an external power source. In this embodiment of the present invention, the second conductive post 91 is connected to the anode conductive metal sheet 92, which is suitable for connection to an external power source, thereby improving the ease of use of the water electrolysis device 100.

[0084] In some embodiments, the second conductive component 9 further includes a second conductive nut 93, which is threadedly connected to the second conductive post 91, and a portion of the anode conductive metal sheet 92 is sandwiched between the second conductive nut 93 and the housing 8 to be fixed to the housing 8.

[0085] In this embodiment of the invention, the second conductive nut 93 not only enables the conductive connection between the second conductive post 91 and the anode conductive metal sheet 92, but also fixes the anode conductive metal sheet 92, thereby improving the assembly efficiency of the water electrolysis module.

[0086] In some specific embodiments, two second conductive posts 91 are provided, the anode conductive metal sheet 92 is elongated and electrically connected to the two second conductive posts 91 respectively, and each of the two second conductive posts 91 is provided with a second conductive nut 93 for fixing the anode conductive metal sheet 92.

[0087] The above technical solution further improves the stability of the connection between the anode conductive metal sheet 92 and the housing 8, as well as the reliability of the conductivity of the anode conductive metal sheet 92.

[0088] In some embodiments, the water electrolysis device 100 further includes: a first support component 11 and a second support component 12, wherein the first support component 11 is disposed in the housing 8 and supports the cathode electrode 3, and the second support component 12 is disposed in the housing 8 and supports the anode electrode 2.

[0089] The above technical solutions further improve the stability of the structures such as the isolation layer 4, cathode electrode 3, proton exchange membrane 1, anode electrode 2, and anode conductive sheet 6, thereby improving the reliability of the water electrolysis device 100.

[0090] In some specific embodiments, the first support component 11 includes a first support column, which passes through the housing 8 and is supported on the cathode electrode sheet 3 or the isolation layer 4. The second support component 12 includes a second support column, which passes through the housing 8 and is supported on the anode electrode sheet 2 or the anode conductive sheet 6.

[0091] In this embodiment of the utility model, the first support component 11 and the second support component 12 have simple structures, are easy to install, and reduce the cost of the water electrolysis device 100.

[0092] It should be understood that the first support component 11 and the second support component 12 can be made of conductive material or insulating material, and this utility model does not limit them in this regard.

[0093] In some embodiments, the flow channel has an inlet 81 and an outlet 82. When assembling the water electrolysis module, a module consisting of a proton exchange membrane 1, an anode electrode plate 2, an anode conductive plate 6, a cathode electrode plate 3, and an isolation layer 4 can be inserted into the flow channel through the inlet 81 or the outlet 82. Then, the first conductive component 5, the second conductive component 9, the first support component 11, and the second support component 12 are assembled. In this embodiment of the invention, the assembly method of the water electrolysis module is simple, reducing the cost of the water electrolysis module.

[0094] In Example 1, the water electrolysis device 100 of this invention was compared with the control group's water electrolysis device 100. The anode and cathode electrode plates 3 used in both devices 100 were made of the same material and were of the same size, with the same current density. The test conditions were identical: water flow rate, water temperature, and constant current input were all the same. The test results are as follows: Figure 4 As shown, the water electrolysis device 100 in Embodiment 1 of this utility model showed no scaling after running for 150 hours.

[0095] In Example 2, a water electrolysis device 100 from Example 2 of this utility model was compared with a control group water electrolysis device 100. The anode and cathode electrode plates 3 used in both water electrolysis devices 100 were of the same material and size, and had the same current density. The test conditions were identical: water flow rate, water temperature, and constant current input were all the same. The test results are as follows: Figure 5 As shown, the water electrolysis device 100 in Embodiment 2 of this utility model showed no scaling after running for 150 hours.

[0096] Other configurations and operations of the water electrolysis device 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0097] The humidifier according to an embodiment of the present invention includes: an atomizing component, a water circuit component, a water holding chamber, and the electrolytic water device 100 described above. The atomizing component atomizes liquid into water mist, the water circuit component guides liquid from the water holding chamber to the atomizing component, and the electrolytic water device 100 is disposed in the water circuit component to electrolyze at least a portion of the liquid.

[0098] The humidifier according to this embodiment of the invention is equipped with an electrolysis water device 100, which effectively reduces bacteria in the liquid, improves the safety of liquid use, and enhances the safety of humidifier use. Furthermore, in the electrolysis water device 100, the insulating layer 4 covers the remaining portion of the surface of the cathode electrode plate 3, occupying space on the surface of the cathode electrode plate 3. This makes it difficult for the substances generated by electrolysis to directly contact the surface of the cathode electrode plate 3, thereby reducing the chance of these substances depositing on the cathode electrode plate 3 and effectively improving the problem of scaling on the cathode electrode plate 3.

[0099] In some embodiments, the atomizing assembly includes: a wet curtain and a fan, wherein the water channel assembly is used to guide liquid to the wet curtain; and the fan is used to control the airflow through the wet curtain.

[0100] When the humidifier is working, the water circuit component guides the liquid in the water chamber to the wet curtain. The surface of the wet curtain absorbs the moisture, and the fan forces airflow to accelerate the evaporation of the moisture on the wet curtain, effectively improving the humidification efficiency of the humidifier.

[0101] In this embodiment of the utility model, the atomizing component includes a wet curtain and a fan. The humidifier adopts the principle of physical evaporation, which improves the efficiency and safety of the humidifier and is especially suitable for long-term operation, large space and high cleanliness scenarios.

[0102] It should be understood that in other embodiments, the atomizing component may also be an ultrasonic atomizing sheet, an electric heating component, or other structures, as long as the atomizing component can atomize the liquid.

[0103] The air treatment device according to an embodiment of the present invention includes: the water electrolysis device 100 described above.

[0104] It should be noted that air handling equipment can be a purifier, a cool fan, a humidifier, an air conditioner, or other equipment that can handle air, and this application does not limit this.

[0105] The air handling equipment according to this embodiment of the present invention is equipped with an electrolytic water device 100, which effectively reduces bacteria in the liquid and improves the safety of liquid use, thereby improving the safety of air handling equipment use. Furthermore, in the electrolytic water device 100, the insulating layer 4 covers the remaining portion of the surface of the cathode electrode plate 3, occupying space on the surface of the cathode electrode plate 3. This makes it difficult for the substances generated by electrolysis to directly contact the surface of the cathode electrode plate 3, thereby reducing the chance of these substances depositing on the cathode electrode plate 3 and effectively improving the problem of scaling on the cathode electrode plate 3.

[0106] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0107] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
