Technical Field

[0001] The invention belongs to the technical field of water electrolysis devices, and in particular relates to an electrode device for water electrolysis. Background Art

[0002] The process of water being electrolyzed by direct current to produce hydrogen and oxygen is called water electrolysis. When current passes through water, hydrogen is formed by reducing water at the cathode and oxygen is formed by oxidizing water at the anode. The amount of hydrogen produced is about twice that of oxygen.

[0003] In the 1960s, Japan had begun to use the characteristics of electrolyzed water to introduce research and applications in medical treatment, beauty care, sewage treatment, and daily life. Electrolyzed water equipment has gradually become a mandatory feature of home life. Usually, electrolyzed water is produced by connecting and fixing two parallel conductive rods or conductive plates. Iridium can be used as a positive electrode material for long-term electrolysis of water in electrolyzed water, but iridium belongs to the platinum rare metal and is very expensive. The cheap electrodes that can be used for electrolyzed water need to be replaced frequently, and the replacement of electrodes after corrosion requires very professional methods and knowledge, otherwise it is easy to cause poor electrode contact or corrosion of the wiring parts and failure. Therefore, it is difficult for electrolyzed water instruments and equipment to be used in civilian daily life.

[0033] In this embodiment, the material of the fixed positive electrode 21 and the fixed negative electrode 22 is titanium. In the present invention, titanium is a non-toxic and corrosion-resistant metal material.

[0034] In the present invention, the device is mainly used for electrolyzing water, purifying water and producing trace element ion water.

[0035] 1. As electrolyzed water, it can be used to wash fruits and vegetables, degrade pesticide residues, and wash the skin for deep cleansing and hydration, thus avoiding or reducing contact with detergent chemicals.

[0036] 2. As a water purifier, it can be used in aquaculture or as an auxiliary treatment for sewage. For example, placing it in a fish pond can reduce the harm of water quality problems to fish and improve the quality of fish. Placing it in a fish tank can reduce or avoid frequent water changes.

[0037] 3. As the production of trace element ion water, it can be used for research and application in science, medicine, beauty and health care, etc. For example, electrodes made of germanium release germanium ions under the action of electrolysis and ionization. The medical research of organic germanium can be applied in tumor treatment, beauty and health care, etc.

[0038] In the present invention, the device uses corrosion-resistant titanium as fixed positive and negative electrodes. Pure titanium cannot release hydrogen. The replaceable positive electrode 23 as the purpose electrode plays the dual role of catalysis and release of trace element ions. When used simply for electrolysis of water, titanium alloy can be considered to be used to make the purpose electrode, which can release relatively less metal ions and have a longer service life. Only by releasing some hydrogen can the characteristic of water with negative ions be maintained. (H2O is partially electrolyzed and ionized to form HO-+H+. When H+ is catalyzed to obtain electrons, it releases hydrogen H, and the ionic water characteristics of HO- are retained in the water. Under the influence of the electrode material, it is inevitable that some ions of the electrode material are dissolved in the process of making ionized water. The concentration of the ions is proportional to the degree of corrosion of the electrode during the electrolysis process).

[0039] In the present invention, the corresponding metal material can be selected as the purpose electrode according to the purpose requirements of the trace element ions. The electrode material used can produce ions identical to those of the electrode material in the liquid due to the effect of electrolytic ionization. This method of quickly obtaining ions can greatly reduce the production cost of metal ions, which is beneficial to the research and application of metal ions in science, medicine, beauty and health care.

[0040] The beneficial effects of the present invention are as follows: compared with the prior art, in the present invention, the replaceable positive electrode 23 is used as the purposeful working electrode, so that the purposeful electrode that is easy to wear out can be made into a consumable and the use cost of electrolyzed water can be greatly reduced, and the electrolyzed water tool for civilian daily use can be realized; the electrode device can be powered by a rechargeable lithium battery or a polymer battery, and the power module 3 can be fully waterproofed by setting the sealed first cavity 11 in the fixing seat 1, and the electrode assembly 2 can be connected to the liquid by setting the hollow second cavity 12 in the fixing seat 1. The liquid flow between the electrode assemblies 2 is unobstructed by the setting of the fixed positive electrode 21, the fixed negative electrode 22, and the replaceable positive electrode 23. The arrangement not only realizes the overall fixing and waterproofing function of the power module 3, but also ensures reliable electrical connection, that is, only the positive and negative electrode parts are in contact with the liquid, thereby fully and effectively solving the electrical connection and waterproofing problems; at the same time, the replaceable positive electrode 23 is sleeved on the fixed positive electrode 21 through an easily replaceable structural arrangement, which not only allows the replaceable positive electrode 23 to be conveniently replaced when the electrode needs to be replaced, but also allows the replaceable positive electrode 23 to form a close contact with the outer surface of the fixed positive electrode 21, so that the replaceable positive electrode 23 also has a good electrical connection, overcoming the difficulty of professionally handling the electrical connection when replacing the electrode. The above-mentioned structural arrangement is simple, so that the device is not only low-cost, but also has a good use effect and is easy to be widely promoted.
