Description
Technical Field
[0001] The present application belongs to the technical field of water electrolysis, and specifically relates to a water electrolysis device. Background Art
[0002] An electrolytic water device is a device that uses water or an aqueous solution to instantly produce electrolytic products such as electrolytic water spray or water jet. The electrolytic water products prepared by it have a high oxidation potential and can be used to relieve or treat inflammatory diseases of the skin and mucous membranes (itchy skin or red and swollen skin), which is equivalent to having anti-inflammatory and antipruritic effects on the skin, and also has the function of killing microorganisms.
[0003] However, the electrolysis products that play a role in disinfection and sterilization are the oxidative products of anode electrolysis; these oxidative products are easily soluble in water, such as water vapor, ozone, oxygen, etc. carrying hydroxyl free radicals, which are mostly in a gas-liquid mixed state; some oxidative products, such as water vapor and ozone carrying hydroxyl free radicals, will quickly obtain hydrogen ions and then be decomposed if they come into contact with the reducing products generated by the cathode. Therefore, if some of the products at the anode end cannot be collected or isolated in time, they will be easily reduced by the cathode products, so that the disinfection and sterilization effect is lost.
[0004] Therefore, how to collect the products at the anode end is a very important problem that needs to be solved urgently in this technical field. Utility Model Content
[0005] The present application provides a water electrolysis device to solve the problem of timely collecting the product at the anode end so as to avoid the product at the anode end being reduced by the product at the cathode end, thereby causing the electrolysis product to lose its disinfection and sterilization effect.
[0006] A water electrolysis device, comprising:
[0007] Raw water supply parts;
[0008] An electrolytic cell, comprising a cathode plate and an anode plate arranged from bottom to top, the electrolytic cell being connectable to the raw water supply member for preparing an electrolytic product having a high oxidation potential;
[0009] A collecting cover, one end of which covers the top of the anode plate, and the other end is connected to one end of a collecting pipe, and the other end of the collecting pipe is arranged outside the raw water supply component; the gas-liquid mixed electrolysis products generated by the anode plate are collected by the collecting cover and discharged to the outside of the raw water supply component through the collecting pipe.
[0010] Preferably, the cross-sectional area of the port at one end of the collecting cover close to the anode plate is larger than the cross-sectional area of the port at the other end.
[0011] Preferably, one end of the collecting cover close to the anode plate is arranged directly above the anode plate.
[0012] Preferably, the other end of the collecting cover is arranged directly above the anode plate.
[0013] Preferably, one end of the collecting cover close to the anode plate is tightly connected to the anode plate, and a water hole is arranged between one end of the collecting cover close to the anode plate and the anode plate.
[0014] Preferably, a gap is provided between one end of the collecting cover close to the anode plate and the anode plate, so that the raw water contacts the anode plate through the gap.
[0015] Furthermore, the other end of the collecting pipe is connected to a drainage aid device, which includes a three-way pipe, and the three-way pipe is respectively connected to the air pump, the other end of the collecting pipe and the discharge port. In this arrangement, the air pump produces high-flow gas. According to the principle that the air flow rate is fast and the air pressure is low, at the three-way pipe, the gas pressure pumped out by the air pump is lower than the gas pressure of the gas-liquid mixed electrolysis product at the other end of the collecting pipe. Therefore, the gas-liquid mixed electrolysis product in the collecting pipe can be quickly discharged from the water electrolysis device through the discharge port under the action of the pressure difference.
[0016] Furthermore, a heating module is arranged in the raw water supply component; the heating module heats the raw water in the raw water supply component; the electrolysis reaction of the raw water after electrolysis heating is more intense, and more gas-liquid mixed electrolysis products are generated at the anode plate, which is conducive to the collection of gas-liquid mixed electrolysis products.
[0017] Furthermore, at least one of the anode plate and the cathode plate is made of conductive diamond.
[0018] Furthermore, one of the anode plate and the cathode plate is made of metal or ceramic.
[0019] Furthermore, the electrolytic cell also includes a diaphragm, and the diaphragm is located between the anode plate and the cathode plate.
[0020] The water electrolysis device provided in the present application is provided with a collecting cover so that the gas-liquid mixed electrolysis products produced by the anode plate are collected through the collecting cover and discharged to the outside of the raw water supply component through a collecting pipe, thereby preventing the gas-liquid mixed electrolysis products produced by the anode plate from being reduced by the hydrogen ions produced by the cathode plate, thereby causing the electrolysis products to lose the disinfection and sterilization effect.

[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0032] It should be noted that the terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices; in addition, for the convenience of explanation, the embodiments provided in this application use the terms "above", "below", "directly above" and "directly below", and it should be noted that this application is not limited to these directions.
[0033] The applicant explains the related technologies mentioned in the background technology as follows:
[0034] The electrolyzed water after electrolysis has a bactericidal and disinfecting function. The electrolytic cell is used to electrolyze the incoming water to produce electrolytic products with bactericidal and disinfecting functions. The specific reaction process is as follows:
[0035] The reaction occurring at the anode is:
[0036] 3H2O→O 3 +6e - +6H +
[0037] 2H2O→O 2 +4e - +4H +
[0038] The reaction occurring at the cathode is:
[0039] O 2 +4e - +4H + →2H2O
[0040] In the reaction at the anode, water molecules lose their hydrogen atoms, and the remaining oxygen atoms combine to form hydroxyl radicals, ozone, and oxygen. Both hydroxyl radicals and ozone are very easy to be reduced, especially hydroxyl radicals, because hydroxyl radicals are originally an intermediate product. + Therefore, the hydroxyl radicals in the water are reduced in nanoseconds and milliseconds. Therefore, if you want to effectively utilize the gas-liquid mixed product produced by the anode (the hydroxyl radicals can be taken out of the electrolytic cell by water vapor, especially when the electrolysis temperature is high), the anode product should be quickly separated from the water and quickly leave the electrode for use, that is, to achieve ready-to-use; this scheme is based on the above ideas to design a new water electrolysis device.
[0041] like Figure 1 As shown, in one embodiment, the water electrolysis device provided by the present application includes:
[0042] Raw water supply parts;
[0043] The electrolytic cell 20 includes a cathode plate 22 and an anode plate 21 arranged from bottom to top, and the electrolytic cell 20 can be connected to a raw water supply member for preparing an electrolytic product with a high oxidation potential;
[0044] The collecting cover 30 has one end covering the top of the anode plate 21, and the other end communicating with one end of a collecting pipe 40, and the other end of the collecting pipe 40 is arranged outside the raw water supply component; the gas-liquid mixed electrolysis products generated by the anode plate 21 are collected by the collecting cover 30 and discharged to the outside of the raw water supply component through the collecting pipe 40.
[0045] In this embodiment, the cathode plate 22 and the anode plate 21 of the electrolytic cell 20 are arranged from bottom to top, mainly to ensure that the anode plate 21 is on top. Since the gas-liquid mixed product generated by electrolysis of the anode plate 21 is generated upward, such an arrangement facilitates the collection of the gas-liquid mixed product by the collection cover 30.
[0046] Similarly, since the gas-liquid mixed product produced by electrolysis of the anode plate 21 is generated upward, the collection cover 30 is arranged above the anode plate 21 to facilitate collection.
[0047] In other embodiments, the raw water supply component can be a water tank 10, or it can be a water pipe that supplies water to the electrolytic cell 20, etc., as long as it is a raw water supply component that can supply water to the electrolytic cell 20, the present application does not limit the structure and form of the raw water supply component; for ease of description, the embodiment of the present application is described in the form of a water tank 10 as the raw water supply component.
[0048] like Figure 1-6 As shown, in other embodiments, the cross-sectional area of the port at one end of the collecting cover 30 close to the anode plate 21 is larger than the cross-sectional area of the port at the other end;
[0049] According to the ideal gas state equation PV=nRT, a reduction in the container volume will lead to an increase in gas pressure, so the collection hood 30 is designed with a larger bottom and smaller top structure. The cross-sectional area through which the gas-liquid mixed product collected by the collection hood 30 passes gradually decreases, and the gas pressure of the gas-liquid mixed electrolysis product gradually increases, which is conducive to the gas-liquid mixed product flowing to the collecting pipe 40.
[0050] like Figure 1-6 As shown, in one embodiment, one end of the collecting cover 30 close to the anode plate 21 is disposed directly above the anode plate 21 .
[0051] In other embodiments, the other end of the collecting cover 30 is disposed directly above the anode plate 21 .
[0052] The collecting cover 30 is located directly above the anode plate 21 and can collect the gas-liquid mixed product to the maximum extent.
[0053] like Figure 1-6 As shown, the present application provides a variety of shapes of the collection hood 30 to meet the requirements of the above embodiments.
[0054] It should be noted that as long as the collecting hood 30 is designed with a larger bottom and smaller top structure, the shape of the cross-sectional area of the port of the collecting hood 30 and the form of the collecting hood are not limited in this application.
[0055] In another embodiment, one end of the collecting hood 30 close to the anode plate 21 is tightly connected to the anode plate 21, and a water hole 31 is provided between the one end of the collecting hood 30 close to the anode plate 21 and the anode plate 21. The collecting hood 30 is tightly connected to the anode plate 21 to prevent the gas-liquid mixed product from overflowing and to collect the generated gas-liquid mixed product to the maximum extent. At the same time, in order to ensure the smooth electrolysis of water in the electrolytic cell 20, the water hole 31 needs to be provided, and the raw water enters through the water hole 31 to contact the anode plate 21, so that the electrolytic cell 20 continuously electrolyzes to generate gas-liquid mixed products.
[0056] In another embodiment, a gap 32 is provided between one end of the collecting cover 30 close to the anode plate 21 and the anode plate 21 , so that the raw water contacts the anode plate 21 through the gap 32 .
[0057] For example, the anode plate 21 is square and the corresponding collecting cover 30 has a square cross section at one end close to the anode plate 21. Figure 4 As shown, the end of the collecting cover 30 close to the anode plate 21 can be connected to the anode plate 21 by bolts or the like, leaving a gap 32 on at least one of the connected sides, or even leaving gaps 32 on all four sides; or Figure 5 As shown, the two sides are connected by connecting plates, etc., with at least one of the connected sides leaving a gap 32, and at most three sides leaving gaps 32;
[0058] The present application does not impose any restrictions on how to leave the gaps 32 and the length and number of the gaps 32, as long as it can ensure that the raw water can contact the anode plate 21 through the gaps 32 to produce an electrolytic reaction.
[0059] like Figure 1 As shown, in another embodiment, the other end of the collecting pipe 40 is connected to a drainage aid device, which includes a three-way pipe 51, and the three-way pipe 51 is respectively connected to the air pump (not shown in the figure, the air pump is connected to the three-way pipe 51 through a high-speed pipe 52), the other end of the collecting pipe 40 and the discharge port 53. With such a configuration, the air pump produces high-flow gas. According to the principle that the air flow rate is fast and the air pressure is low, at the three-way pipe, the gas pressure pumped out by the air pump is less than the air pressure of the gas-liquid mixed electrolysis product at the other end of the collecting pipe 40. Therefore, the gas-liquid mixed electrolysis product in the collecting pipe 40 can be quickly discharged from the water electrolysis device through the discharge port 53 under the action of the pressure difference.
[0060] like Figure 6As shown, in another embodiment, a heating module 60 is provided in the water tank 10; the heating module 60 heats the raw water in the water tank 10; the raw water after electrolysis heating has a more intense electrolysis reaction, and more gas-liquid mixed electrolysis products are generated at the anode plate 21, which is conducive to the collection of gas-liquid mixed electrolysis products;
[0061] It should be noted that the heating module 60 provided in this embodiment is a heating tube arranged in the water tank 10. As long as it can heat the raw water in the water tank 10, this application does not limit the structural form of the heating module 60. In addition to the heating tube, it can also be other forms such as chemical heating and heating rods.
[0062] In another embodiment, the anode plate 21 uses conductive diamond particles; the cathode plate 22 uses metal particles or conductive ceramic particles, wherein the metal particles include at least one of titanium, platinum, gold, titanium alloy, nickel, palladium, platinum-ruthenium alloy or stainless steel.
[0063] In other embodiments, both the anode plate 21 and the cathode plate 22 are made of conductive diamond particles.
[0064] In other embodiments, the anode plate 21 and the cathode plate 22 are both made of metal particles or conductive ceramic particles, wherein the metal particles include at least one of titanium, platinum, gold, titanium alloy, nickel, palladium, platinum-ruthenium alloy or stainless steel.
[0065] like Figure 2 As shown, in one embodiment, the electrolytic cell 20 further includes a diaphragm 23, which is located between the anode 21 and the cathode 22. The diaphragm 23 can further prevent the anode product from contacting the cathode product, avoid the anode product from being immediately oxidized, and provide time for collecting the anode product.
[0066] In summary, the water electrolysis device provided in the present application can avoid the reaction between the gas-liquid mixed product produced by the anode and the cathode product, thereby affecting the sterilization and disinfection effect of the water electrolysis device, because the collection cover can collect and discharge the gas-liquid mixed product produced by the anode in time.
[0067] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
