Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to an electrode structure for electrolyzing water. Background Art

[0002] Hydrogen water, or hydrogen-rich water, refers to water that contains a large amount of hydrogen. It is generally produced by magnetization, ultrasonic treatment, ore treatment, mineral treatment or electrolysis. Among these methods, the fastest and most effective is electrolysis. Hydrogen water produced by electrolysis is called electrolyzed hydrogen water.

[0003] Electrolyzed hydrogen water can be used as drinking water, beauty water, industrial and agricultural water, etc. Many reports point out that in the field of semiconductors and display screens, electrolyzed hydrogen water has a better cleaning power than ultrapure water; in the field of agriculture, electrolyzed hydrogen water has the effect of accelerating growth and preventing pests and diseases, and has an excellent effect on long-term preservation of food; in the field of beauty and health care, electrolyzed hydrogen water has an excellent soothing and improving effect on atopic dermatitis, skin whitening, aging, lifestyle diseases, etc.

[0004] In the prior art, patent number CN201620853696.7 is an improved electrode structure of a hydrogen water generator, which includes a positive electrode element with positive charge and a negative electrode element with negative charge, characterized in that the positive electrode element and the negative electrode element are made of metal materials, and the positive electrode element and the negative electrode element are also electrically connected to the first conductive part and the second conductive part respectively. At the same time, the positive electrode element and the negative electrode element are continuously bent and staggered and arranged at a distance to increase the surface area of ​​water molecules contacting the positive electrode element and the negative electrode element, thereby improving the efficiency of the electrolysis reaction.

[0005] In the prior art, patent number CN201720514906.4 discloses a hydrogen water generator, including a reinforcing sheet A, a generator A, a mesh electrode sheet, an ion membrane, a generator B and a reinforcing sheet B, wherein the reinforcing sheet A, the generator A and the mesh electrode sheet form an electrolytic cell A, the mesh electrode sheet, the generator B and the reinforcing sheet B form an electrolytic cell B, and the ion membrane is located between the electrolytic cell A and the electrolytic cell B. There are two mesh electrode sheets, which are respectively installed on the inner side of the generator A and the generator B, and an ion membrane is provided between the two mesh electrode sheets. After the water is flowed and electrolyzed, the hydrogen-rich water can be conveniently collected and used, which is superior to the performance of conventional electrolytic cells, and can be used at any time, eliminating the disadvantage that hydrogen-rich hydrogen water is not easy to store. And the flowing water is easy to collect, which changes the problem that the ion water electrolyzed in the traditional electrolytic cell is difficult to collect.

[0006] In the prior art, Patent No. CN202020275481.8 discloses a hydrogen water production system, including a hydrogen production module and a drinking water tank, the hydrogen production module is provided with a gas flow channel for discharging the produced gas, the gas flow channel includes a hydrogen flow channel, the drinking water tank is connected to a drinking water pipe, and the hydrogen flow channel is connected to the drinking water pipe to produce hydrogen water. The hydrogen production module includes a proton exchange layer, both sides of the proton exchange layer are provided with a diffusion layer, a bipolar plate, an electrode and an end plate, the diffusion layer, the bipolar plate, the electrode and the end plate are arranged in sequence from the inside to the outside, and also includes a gas flow channel, the first end of the gas flow channel is located between the two end plates, the second end of the gas flow channel extends out of the end plate, and the gas flow channel located between the two end plates is at least partially curved. The hydrogen pressure in this hydrogen water production system is high, which is also conducive to cooling the hydrogen production module.

[0007] Even so, the electrodes of the existing electrolyzed hydrogen water production device still have the following problems:

[0008] 1. The electrolysis container is usually equipped with metal electrodes and / or activated carbon porous material electrodes. Since DC voltage is used as the electrolysis voltage, calcium carbonate is generated from the calcium dissolved in the water and deposited on the electrode surface where the electrode action occurs. Continuous use will have a negative impact on the electrolysis efficiency. Therefore, it is necessary to regularly use acidic agents, such as citric acid, to clean the electrodes and perform repair operations to remove calcium carbonate.

[0009] 2. The electrolysis efficiency is determined by the relative area of ​​the positive electrode and the negative electrode. For cup-shaped or kettle-shaped electrolysis containers, due to space limitations, the positive electrode and the negative electrode are usually arranged up and down. However, the up and down arrangement is not easy to perform electrode cleaning and repair operations because calcium carbonate is mainly deposited on the surface opposite to the positive electrode and the negative electrode, that is, calcium carbonate is mainly deposited in the middle of the electrode sheets arranged up and down.

[0010] 3. The vertical electrodes with positive and negative electrodes arranged on the left and right are easier to clean and repair, but their area is relatively small and the electrolysis efficiency is low.

[0011] Therefore, how to effectively increase the relative area of ​​the positive and negative electrodes while facilitating the cleaning of the electrodes remains a major challenge in the field of hydrogen water technology. Utility Model Content

[0012] In order to solve the problems still existing in the prior art, the main purpose of the utility model is to provide an electrode structure that can be used in a hydrogen water generator, which can effectively increase the relative area between the positive electrode and the negative electrode to improve the electrolysis efficiency and facilitate the cleaning and repair operation of the electrode.

[0013] In order to achieve at least one of the aforementioned advantages, the first preferred embodiment of the present invention is an electrode structure, including a negative electrode sheet and a positive electrode sheet, wherein the negative electrode sheet and the positive electrode sheet are both horizontal sheets with the same thickness.

[0014] The negative electrode sheet has a plurality of first protrusions and a plurality of first recesses, and the positive electrode sheet has a plurality of second protrusions and a plurality of second recesses. The first protrusions extend into the second recesses, and the second protrusions extend into the first recesses, so that a first groove is formed between the first protrusions and the second recesses and between the second protrusions and the first recesses, and the first groove has a plurality of first arc segments and a plurality of first straight segments. The first arc segment has a first width, and the plurality of first straight segments have the same second width, and the first width is greater than the second width, so that electrolysis occurs uniformly and stably in the first straight segment.

[0015] Furthermore, the negative electrode sheet further includes at least one third protrusion and at least one third recess, and the positive electrode sheet further includes at least one fourth protrusion and at least one fourth recess. The third protrusion extends into the fourth recess, and the fourth protrusion extends into the third recess. A second groove is formed between the third protrusion and the fourth recess and between the fourth protrusion and the third recess. The second groove has a plurality of second arc segments and a plurality of second straight line segments, the second arc segment has a third width, the plurality of second straight line segments have the same fourth width, and the third width is greater than the fourth width.

[0016] In order to achieve at least one of the aforementioned advantages, a second preferred embodiment of the present invention is a hydrogen water generator, characterized in that it includes an electrode structure as described in the aforementioned first preferred embodiment.

[0017] The electrode structure and hydrogen water generator proposed by the utility model, although the negative electrode sheet and the positive electrode sheet are both horizontal sheets, they are respectively provided with mutually matching recessed parts and protruding parts, so that the two can intersect each other in the horizontal direction, forming the first groove part and the second groove part without contact, and the two sides of the groove wall of the first groove part and the second groove part form the vertically opposite negative electrode and positive electrode. Because the overall area of ​​the groove wall is larger than the horizontal area of ​​the negative electrode sheet and the positive electrode sheet, the electrolysis efficiency is improved; and because the first groove part and the second groove part have upper and lower openings, it is convenient to use a brush to wash and clean, and the overall efficiency is significantly improved.

The utility model can be specifically implemented in many alternative forms and should not be interpreted as being limited to only the embodiments disclosed herein.

In the description of the present utility model, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variation thereof means "at least including".

[0033] It should also be understood that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" in the description of the present invention should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. A person of ordinary skill in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0034] Unless the context clearly indicates otherwise, the terms "one", "an item" in the description of the present invention are also intended to include a plurality. It should also be understood that the terms "include" and / or "comprise" stipulate the existence of the stated features, steps, operations, units and / or components, but do not exclude the existence or addition of one or more other features, steps, operations, units, components and / or combinations thereof.

[0035] The first preferred embodiment of the present invention is as follows Figure 1 As shown, an electrode structure can be used in but not limited to a cup-shaped, pot-shaped, or barrel-shaped hydrogen water generator.

[0036] The electrode structure comprises a negative electrode sheet 100 and a positive electrode sheet 200 . The negative electrode sheet 100 and the positive electrode sheet 200 are both horizontal sheets with the same thickness.

[0037] Although the negative electrode sheet 100 and the positive electrode sheet 200 are both horizontal sheets, they are not arranged one on top and the other on the bottom, because such an arrangement will cause the calcium carbonate produced by electrolysis to be deposited on the electrode surface between the upper and lower electrodes, making it difficult to clean the electrode sheets. Figure 2 The negative electrode sheet 100 has a plurality of first protrusions 111 and a plurality of first recesses 121. Figure 3 The positive electrode sheet 200 has a plurality of second protrusions 212 and a plurality of second recesses 222 distributed horizontally. Figures 1 to 3 The first protrusion 111 of the negative electrode sheet 100 extends into the second recessed portion 222 of the positive electrode sheet 200, so that a first groove portion 310 is formed between the first protrusion 111 and the second recessed portion 222; the second protrusion 212 of the positive electrode sheet 200 extends into the first recessed portion 121 of the positive electrode sheet 200, so that a first groove portion 310 is also formed between the second protrusion 212 and the first recessed portion 121.

[0038] The side wall of the first groove 310 is the electrode surface for electrolysis to generate hydrogen water. In other words, although the negative electrode sheet 100 and the positive electrode sheet 200 of this embodiment are horizontal sheets, they are actually electrolyzed in a vertical electrode manner. Therefore, after electrolysis, calcium carbonate is mainly deposited on the side wall of the first groove 310. When the hydrogen water generator is in the shape of a cup, a kettle, or a barrel, even if the negative electrode sheet 100 and the positive electrode sheet 200 proposed by the utility model are set at the bottom of the hydrogen water generator, it is still very easy to use a brush to reach in from the top to scrub and clean the groove wall of the first groove 310.

[0039] The electrolysis efficiency depends on the relative area of ​​the negative electrode sheet and the positive electrode sheet. In order to improve the electrolysis efficiency, the first groove 310 of the present invention is not a simple straight line. Figure 1 The first groove 310 has a plurality of first arc segments 311 and a plurality of first straight segments 312. The more the number of first straight segments 312, the longer the first groove 310. To further explain, the first arc segments 311 are provided to connect the plurality of first straight segments 312, so that the first groove 310 can be connected as a whole.

[0040] When water is electrolyzed by the negative electrode sheet and the positive electrode sheet to generate hydrogen and oxygen, the hydrogen and oxygen will not necessarily be generated uniformly from the surface of the negative electrode sheet and the positive electrode sheet, but will be generated from the position with the shortest distance between the negative electrode sheet and the positive electrode sheet, so the relative distance setting between the negative electrode sheet and the positive electrode sheet is very important. In this embodiment, all the first straight line segments 312 have the same second width 342. When the number of the first straight line segments 312 is greater, the electrolysis efficiency is better.

[0041] Furthermore, since the plurality of first straight line segments 312 are connected by the first arc segment 311, and the first arc segment 311 has a first width 341, it is preferred that the first width 341 is slightly larger than the second width 342. The reason why the first width 341 of the first arc segment 311 is slightly larger than the second width 342 of the first straight line segment 312 is to protect the electrode sheet and extend the life of the electrode sheet. Because, in the first arc segment 311, the circumference of the inner arc is smaller than the circumference of the outer arc, the inner edge area of ​​the groove is smaller than the outer edge area of ​​the groove, and when electrolysis occurs, the electrode on the inner edge side will be greatly worn out. When the difference between the inner edge area and the outer edge area is larger, the wear of the electrode on the inner edge side is more serious. Therefore, when the first width 341 of the first arc segment 311 is slightly larger than the second width 342 of the first straight segment 312, electrolysis occurs evenly only in the first straight segment 312, and basically no electrolysis reaction occurs in the first arc segment 311, which can effectively maintain the service life of the negative electrode sheet 100 and the positive electrode sheet 200.

[0042] Preferably, the sidewall of the first groove 310 is perpendicular to the horizontal surface of the negative electrode sheet 100 and the positive electrode sheet 200, so as to maintain the stability of electrolysis, facilitate cleaning, and extend the service life of the electrode sheet.

[0043] In order to increase the relative area of ​​the positive electrode and the negative electrode and improve the electrolysis efficiency, preferably, the thickness of the electrode sheet is greater than the second width 342 of the first straight line segment 312, and preferably more than twice the second width 342. More specifically, the second width 342 is between 1.0 mm and 2.0 mm, and the thickness of the negative electrode sheet 100 and the positive electrode sheet 200 is between 2.5 mm and 5.0 mm.

[0044] Please continue to see Figure 1 In order to facilitate manufacturing and effectively utilize the electrode sheet area, the negative electrode sheet 100 and the positive electrode sheet 200 are roughly formed into a symmetrical shape after being combined, and the negative electrode sheet 100 and the positive electrode sheet 200 are point-symmetrical with respect to the center of the symmetrical shape.

[0045] In one embodiment, the negative electrode sheet 100 further includes at least one third protrusion 113 and at least one third recess 123, and the positive electrode sheet 200 further includes at least one fourth protrusion 214 and at least one fourth recess 224. The third protrusion 113 of the negative electrode sheet 100 extends into the fourth recess 224 of the positive electrode sheet 200, and the fourth protrusion 214 of the positive electrode sheet 200 extends into the third recess 123 of the negative electrode sheet 100, so that a second groove 320 is formed between the third protrusion 113 and the fourth recess 224 and between the fourth protrusion 214 and the third recess 123.

[0046] Preferably, the third protrusion 113 of the negative electrode sheet 100 is perpendicular to the first protrusion 111 , and the fourth protrusion 214 of the positive electrode sheet 200 is perpendicular to the second protrusion 212 , which is more conducive to manufacturing.

[0047] The second groove 320 has a plurality of second arc segments 321 and a plurality of second straight segments 322. The second arc segment 321 is used to connect the plurality of second straight segments 322 so that the second groove 320 can be connected front to back. The second arc segment 321 has a third width 343, and the plurality of second straight segments 322 have the same fourth width 344. The third width 343 is greater than the fourth width 344.

[0048] As mentioned above, in the arc segment, the circumference of the inner arc is smaller than the circumference of the outer arc, so the inner edge area of ​​the groove is smaller than the outer edge area of ​​the groove. When electrolysis occurs, the electrode on the inner edge side will be greatly damaged. When the difference between the inner edge area and the outer edge area is larger, the loss of the electrode on the inner edge side is more serious. Therefore, when the third width 343 of the second arc segment 321 is slightly larger than the fourth width 344 of the second straight line segment 322, electrolysis only occurs in the second straight line segment 322 and does not occur in the second arc segment 321, which can effectively maintain the service life of the negative electrode sheet 100 and the positive electrode sheet 200.

[0049] Preferably, the sidewall of the second groove 320 is perpendicular to the horizontal surface of the negative electrode sheet 100 and the positive electrode sheet 200, so as to maintain the stability of electrolysis, facilitate cleaning, and extend the service life of the electrode sheet.

[0050] By connecting the first arc segment 311 with the plurality of first straight segments 312 and the second arc segment 321 with the plurality of second straight segments 322 , the overall area of ​​the first groove portion 310 and the second groove portion 320 can be significantly increased, and the electrolysis efficiency is further improved.

[0051] In order to improve the durability of the electrode, preferably, a platinum layer is formed on the plated surface of the sidewalls of the first groove portion 310 and the second groove portion 320 .

[0052] Based on the same technical idea, the utility model also proposes a second preferred embodiment, which is a hydrogen water generator, which includes an electrode structure, and is characterized in that the electrode structure used is the electrode structure described in the first preferred embodiment.

[0053] In summary, the electrode structure and hydrogen water generator proposed by the utility model, although the negative electrode sheet and the positive electrode sheet are both horizontal sheets, they are respectively provided with mutually matching recessed parts and protruding parts, so that the two can intersect each other in the horizontal direction, forming the first groove and the second groove of the same width without contact, and the two sides of the groove wall of the first groove and the second groove form the vertically opposite negative and positive electrodes. Because the overall area of ​​the groove wall is larger than the horizontal area of ​​the negative electrode sheet and the positive electrode sheet, the electrolysis efficiency is improved; and because the first groove and the second groove have upper and lower openings, it is convenient to use a brush to wash and clean, and the overall efficiency is significantly improved.

[0054] The above preferred embodiments are described in detail to more clearly describe the features and spirit of the present invention, but are not intended to limit the scope of the present invention by the preferred embodiments disclosed above. On the contrary, the purpose is to cover various equivalent changes within the scope of the claims to be applied for the present invention.
