Description

Technical Field

[0001] The utility model relates to the technical field of electrolyzed water. Background Art

[0002] Using water or aqueous electrolyte as raw materials, an aqueous solution containing oxidized groups can be produced by an electrolysis device. The structure of the electrolysis device is composed of an anode and a cathode, or an anode, a cathode and a membrane sandwiched in the middle that acts as a proton exchange. The ozone, oxygen atoms, and hydroxyl radicals produced by the electrolysis device can effectively kill bacteria and viruses, so they can be well used in daily disinfection. In the existing electrolysis structure, it is necessary to precisely dispense glue on the connection surface of the conductive sheet connecting the electrode, and then lock and fix the other end. During the fixing process, the conductive sheet may slide or bounce, thereby contaminating the effective electrolysis area of ​​the electrode sheet.

[0003] The electrolytic water structure can produce electrolytic water that kills bacteria and viruses, and after oxidation and sterilization, it is converted into ordinary water, which can achieve green disinfection. It is suitable for use in electrical appliances and is suitable for various usage scenarios. However, implanting the electrolytic structure inside the appliance will inevitably increase the overall volume, resulting in poor usability and low portability. The current structure cannot meet the needs of small appliances for lightweight and portability. Utility Model Content

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] As Figure 1 shown, it is an electrolysis component of a preferred embodiment of the present utility model, including a housing 1 and a laminate 2. The laminate 2 is disposed inside the housing 1. The laminate 2 includes a first electrode 23, an electrolyte membrane 22, and a second electrode 21 stacked in sequence. The first electrode 23 is connected to a conductive sheet 4. The conductive sheet 4 is provided with a glue injection hole 41, and the glue injection hole 41 is filled with a conductive glue 7.

[0028] In the prior art, to ensure stable electrical conduction connection, the conductive sheet is connected and installed to the electrode sheet through a row of conductive contacts, resulting in waste of the effective electrolysis area. In the electrolysis structure of the present application, the conductive sheet is led out through small-area contacts. Compared with the existing large-area conductive contacts in a row, the contact area occupied is significantly reduced. While effectively increasing the working area of the electrode, the overall electrolysis structure is miniaturized. To achieve electrical conduction connection between the conductive sheet and the electrode in a structure with small-area contacts, the injected conductive adhesive 7 can improve the electrical conductivity of the contacts, reduce the internal resistance, and ensure the electrolysis stability of the electrolysis component. In the present application, a glue injection hole 41 is opened at one end of the conductive sheet 4 connected to the electrode sheet, so that the conductive sheet 4 can be pre-fixed and installed at one end far from the electrode sheet first, and then conductive silver glue is injected into the glue injection hole 41 to achieve the bonding of the conductive sheet and the electrode sheet. This avoids the precision requirements for precise dotting of the connection surface of the conductive sheet 4 in the traditional structure, solves the problem that the silver glue on the connection surface of the conductive sheet 4 in the existing structure contaminates the effective electrolysis area of the electrode sheet, reduces the contact area occupied, provides stable electrical conduction connection, increases the effective electrolysis area of the electrode sheet, makes the entire electrolysis structure more compact, miniaturizes the size, saves space, and is particularly suitable for various small appliances.

[0029] To achieve the pre-fixation of one end of the conductive sheet 4 far from the electrode sheet before glue injection, in one embodiment, a first conductive pin 31 is connected to one end of the conductive sheet 4 far from the first electrode 23. Further, the conductive sheet 4 and the first conductive pin 31 are fixed by bolts. For example, the bolts fix the conductive sheet 4 and the conductive pin to the housing 1.

[0030] In one embodiment, a gap 209 is formed between the conductive sheet 4 and the first electrode 23, and the gap 209 is filled with the conductive adhesive 7.

[0031] For example, a glue injection groove (the glue injection groove is the gap 209) is opened at the position where the first electrode 23 is connected to the conductive sheet 4. The conductive adhesive 7 enters the glue injection groove through the glue injection hole 41 and is filled, which increases the contact area between the conductive adhesive 7 and the first electrode 23 and the conductive sheet 4, ensures good electrical conduction connection, and after the conductive adhesive 7 solidifies, the conductive sheet 4 and the first electrode 23 can be firmly connected, improving the overall reliability of the electrolysis structure.

[0032] In one embodiment, the surface of the first electrode 23 is a crystal structure, that is, the material of the catalyst layer of the first electrode 23 is crystal (or the first electrode 23 is formed of a crystal material as a whole), and the top of the crystal is a sharp angular structure, that is, there is a gap 209 between the crystal tips on the surface of the first electrode 23. Therefore, when the conductive sheet 4 is pressed on its surface, the gap 209 between the conductive sheet 4 and the crystal tip reduces its contact area, resulting in increased resistance and hindering conductive connectivity. Through the opened injection hole 41, the conductive glue 7 is injected and filled in the gap 209 formed between the conductive sheet 4 and the first electrode 23, thereby increasing the contact area, reducing resistance, and ensuring good conductive connectivity. After the conductive glue 7 solidifies, a stable connection between the conductive sheet 4 and the first electrode 23 can be achieved, thereby improving the overall reliability of the electrolysis structure.

[0033] In order to provide a better glue injection effect, the conductive glue 7 can flow from the glue injection hole 41 into the gap 209 to ensure a good contact area. In one embodiment, the relationship between the aperture D of the glue injection hole 41 and the crystal tip structure d of the crystal is: 10d<D<1Md. Wherein, M is mega. Within this range, the conductive glue can flow quickly and fully into the gap to ensure the stability of the conductive connection.

[0034] In one embodiment, the material of the first electrode 23 and / or the second electrode 21 is at least one of conductive silicon and conductive diamond, or the material of the first electrode 23 and / or the second electrode 21 is one of titanium, platinum, lead, tantalum, iridium, palladium, antimony or its oxide. In one embodiment, the electrode material of the first electrode 23 and the second electrode 21 is the same, and the first electrode 23 and the second electrode 21 can achieve electrode conversion by converting current, thereby reducing the problem of scale such as calcium carbonate adhering to the electrode surface.

[0035] In one embodiment, the conductive sheet 4 is connected to the side of the first electrode 23 facing the second electrode 21. Furthermore, the electrolyte membrane 22 is staggered from the conductive sheet 4. In this embodiment, by arranging the conductive sheet 4 connected to the first electrode 23 on the side of the first electrode 23 facing the second electrode 21, that is, arranging the conductive sheet 4 in the gap 209 between the first electrode 23 and the second electrode 21, the electrolyte membrane 22 is staggered from the conductive sheet 4, thereby saving space in the thickness direction of the electrolytic structure, and the entire electrolytic structure is more compact and miniaturized, and is particularly suitable for various small electrical appliances.

[0036] The laminate 2 of the present application is formed by sequentially arranging a first electrode 23, a solid electrolyte membrane 22, and a second electrode 21. There may be a gap between each layer or they may be attached to each other's surfaces. For example, in order to facilitate the flow of water and gas, a gap 209 is provided between the first electrode 23 and the solid electrolyte membrane 22, and between the solid electrolyte membrane 22 and the second electrode 21. Alternatively, the first electrode 23 and / or the second electrode 21 may be movably arranged in the electrolysis chamber. For example, the first electrode 23 and / or the second electrode 21 is provided with an elastic structure, and a slight movement is achieved through the elastic structure to adjust the gap 209 between the layers.

[0037] Among them, the first electrode 23 and the second electrode 21 are externally connected to a power supply voltage to electrolyze the flowing water at a low voltage to generate electrolyzed water. The electrolyzed water contains oxidizing groups such as hydroxyl radicals, ozone, and oxygen atoms, which can achieve oxidative sterilization and disinfection.

[0038] In one embodiment, in order to achieve conductivity, one end of the conductive sheet 4 away from the first electrode 2323 is connected to a first conductive pin 31, and the first conductive pin 31 is connected to an external power supply.

[0039] In one embodiment, in order to achieve conductivity, the second electrode 21 extends to form a conductive connection end 211, and the conductive connection end 211 is connected to a second conductive pin 33, and the second conductive pin 33 is connected to an external power supply.

[0040] In one embodiment, the second electrode 21 extends to form a conductive connection end 211, and the conductive connection end 211 is formed with a bent portion 212, and the bent portion 212 has elasticity. By providing the bent portion 212 at the conductive connection end 211, the second electrode 21 can achieve a certain elastic movement while being fixed, adjust the electrode spacing, and make the entire electrolysis structure more compact and miniaturize the size while achieving elastic buffering.

[0041] For example, the conductive connection end 211 is installed on the second conductive pin 33 through a screw. The screw presses the second electrode 21 against the solid electrolyte membrane 22 through the conductive connection end 211, and at the same time realizes elastic tightness. Compared with other existing elastic structures, the structure is more compact, can achieve the effect of reducing the volume, and miniaturizes the size.

[0042] In one embodiment, the conductive sheet 4 is formed with a bent portion 212, and the bent portion 212 has elasticity. By providing the bent portion 212 on the conductive sheet 4, the first electrode 23 can achieve a certain elastic movement while being fixed, adjust the electrode spacing, and make the entire electrolysis structure more compact and miniaturize the size while achieving elastic buffering.

[0043] In one embodiment, through holes 205 are provided in the first electrode 23, the electrolyte membrane 22, and the second electrode 21. Through the provided through holes 205, water can flow between the two ends of the first electrode 23 and the second electrode 21, and the oxidation groups generated between the electrodes and the solid electrolyte membrane 22 can be quickly carried away by the water flow.

[0044] Among them, the first electrode 23 and the second electrode 21 are determined by the power source / voltage electrically connected thereto. By reversing the power source / voltage connected thereto, electrode conversion can be achieved, thereby reducing the problem of scale such as calcium carbonate adhering to the electrode surface.

[0045] This application provides a dental irrigator, including the electrolysis component described above. For example, the dental irrigator includes a body and a nozzle. The body is connected to the nozzle. A water tank, a water pump, and the electrolysis component are arranged in the body. The water pump pumps the water in the water tank to the electrolysis component to be converted into electrolyzed water. The electrolyzed water is transported to the nozzle and sprayed out to act on the user's oral cavity. The electrolyzed water contains oxidation groups such as ozone, oxygen atoms, and hydroxyl free radicals, which can effectively kill bacteria and viruses in the oral cavity and achieve the purpose of repairing gum and tooth problems and nursing the oral cavity. The structure of this electrolysis component is compact and miniaturized, which is very suitable for application in dental irrigator products.

[0046] This application provides an electrical appliance, including the electrolysis component described above. For example, an electric toothbrush, for example, a feminine care device, for example, a dishwasher, for example, a refrigerator disinfector, for example, a sprayer. In this embodiment, they will not be described in detail one by one. By arranging the electrolysis component inside the electrical appliance to output electrolyzed water, external bacteria and viruses can be effectively killed, the home environment can be purified, and human health can be protected.

For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
