The problem of poor rust prevention effect of the existing heating kettle based on the background technology. The utility model provides a heating kettle, which aims to perform rust protection on the metal inner wall of the heating kettle by utilizing a cathode protection technology, so that the rust corrosion on the metal inner wall of the heating kettle is avoided, and the user experience is improved.
When the metal inner wall of the housing of the heating kettle is in contact with oxygen and water in the air, the electrochemical reaction process on the metal inner wall can be divided into the following processes.
Oxidation of metal surfaces: the surface of the inner wall of the metal first reacts with oxygen in the air to form a metal oxide. Oxygen molecules (O) in oxygen 2 ) From the air, adsorbed onto the metal inner wall, and then some metal atoms lose electrons and combine with oxygen molecules to form metal oxides.
The water participates in: when the inner wall of the metal contacts with moisture, oxygen ions (OH-) in the moisture react with metal ions (M+) in the metal oxide to generate metal hydroxide. Meanwhile, the metal ions on the inner wall of the metal can also react with hydrogen ions (H+) in the moisture to form metal hydrate.
Electron transfer: after forming a compound such as an oxide or a hydrate on the surface of the metal inner wall, electrons are transferred through a conductive path on the surface of the metal inner wall due to a slight potential difference between the metal inner wall and moisture.
Corrosion reaction: during electron transfer, metal oxides and metal hydrates formed on the inner walls of the metal may be reduced to metal ions and water. These metal ions can then react with new moisture, continuing to produce new metal oxides and metal hydrates. This cyclic process can lead to progressive corrosion and formation of rust on the inner walls of the metal.
Thus, in general, the rusting process of heating the metal inner wall of a kettle is a continuous cycle of electrochemical reactions, including metal oxidation, moisture participation, electron transfer, and the reaction of metal ions with moisture to form new metal oxides and metal hydrates. The whole process can lead to corrosion and rust on the inner wall of the metal.
In general, the cathodic protection technology is an electrochemical protection technology, and the principle is that an external direct current is applied to the surface of a corroded metal structure, and the corroded metal structure is set as a cathode, so that electron migration caused by metal corrosion is inhibited, and the occurrence of metal corrosion is avoided or reduced.
