At present, the principle of household disinfection cabinets can be divided into two types, one is the more traditional infrared sterilization cabinet, and the other is the more widely used and advanced ultraviolet ozone low-temperature sterilization cabinet. These two disinfection methods are widely used in the current household disinfection cabinet products, and can be more effective tableware disinfection. However, there is still a certain gap between the two methods, which is not only reflected in the sterilization efficiency, but also has certain requirements for the types of tableware.

Simple and Rough-Disinfection Cabinet Principle: Infrared High Temperature Disinfection Cabinet
The principle of the infrared high-temperature disinfection cabinet is relatively single. The disinfection cabinet generates infrared rays through the built-in infrared generating device, which heats the tableware and the inner wall as a whole, so that the tableware and the overall environment are in a high temperature environment above 120°C, and the high temperature is used to make the surface of the tableware Bacterial intracellular proteins deteriorate, and then achieve the effect of disinfection and sterilization.
However, the principle of this disinfection cabinet has higher requirements for tableware materials. Some heat-resistant materials cannot be put into disinfection. For example, the materials we use most, such as plastic, wood, bamboo, lacquerware and other materials, are likely to cause deformation, melting, cracking, and even toxicity due to changes in properties. This method of disinfection using high temperature is simple and reliable, and may be regarded as the most traditional sterilization method we use. The infrared sterilization method is relatively simple, the cost is low, and all kinds of tableware cannot be disinfected, so they are basically low-end products.

Efficient and Practical-Disinfection Cabinet Principle: Ultraviolet Ozone Low Temperature Disinfection Cabinet
The working principle of the ultraviolet ozone low-temperature disinfection cabinet is more advanced, and it is more suitable for current family use. At the same time, the requirements for the material of the tableware itself are less, and almost all kinds of tableware materials can be disinfected. We know that high temperature can quickly and efficiently make bacteria inactive, but it will also strictly limit the types of tableware materials, and too high temperature is also a waste of energy. Therefore, this disinfection cabinet is heated at a low temperature of no more than 75 ℃. This temperature can kill a large number of bacteria and achieve the effect of sterilization and disinfection. At the same time, it will not cause damage to tableware due to high temperature. Even wood, bamboo and even ordinary heat-resistant plastics that are relatively heat-resistant can be put into it for disinfection and sterilization.
Ultraviolet rays and ozone are currently widely used disinfection methods in industry and household use, and both belong to physical sterilization methods. There is no need to worry about residues in normal use environments, and they are relatively safe to use. Ultraviolet has a strong bactericidal effect, especially ultraviolet rays with a wavelength of 253.7nm can effectively kill bacteria on the surface of direct objects and play a strong role in preventing regeneration. However, the penetration of ultraviolet rays is extremely poor, and there is almost no sterilization effect for areas without direct irradiation, so at this time, ozone, the same powerful sterilization method, is needed to match it.
Ozone has a strong oxidizing ability and can directly destroy bacterial DNA, RNA, proteins and enzymes, causing bacteria and viruses to lose their activity. And this sterilization method is different from ultraviolet rays. It will fill the entire space, disinfect and sterilize all positions in the disinfection cabinet, and there will be no dead ends. After the sterilization is completed, ozone will gradually decompose into oxygen due to its strong oxidation and instability, and will not produce serious residue or leakage.
Therefore, we clearly see that the disinfection cabinet is a very practical and necessary household appliance in our home, especially in the era of rapid improvement in the quality of life, more and more consumers begin to care about the quality of life and health, and the existence value of disinfection cabinet is becoming more and more important.
