[0002] Ozone is an allotrope of oxygen, a form of oxygen in a high-energy state. It is extremely unstable and can be decomposed and reduced to oxygen and oxygen atoms at any time at room temperature. At this time, oxygen atoms have a strong oxidizing ability. It can quickly penetrate the cell membrane of bacterial cells and kill bacteria; it can react with viral protein films to kill viruses; when it encounters organic matter and various odors, it undergoes oxidation reactions to generate non-toxic substances. Ozone's functions of sterilization, disinfection, decomposition of dirt and odors, and reduction of pure oxygen play a role in purifying the air and quickly decompose harmful substances such as formaldehyde and toluene in the air.

[0003] The ozone generator is a device used to produce ozone gas, and the discharge tube in the ozone generator needs to be connected to the external power supply terminal through the high-voltage terminal. Therefore, higher requirements are placed on the sealing of the high-voltage terminal. At present, the assembly of the high-voltage terminal is achieved by combining fasteners, intermediate parts and fixing parts. Among them, the intermediate part is the main part in contact with the high-voltage terminal. The specific structure is as follows: Figure 1 As shown, however, in actual use, its sealing performance is insufficient and needs to be improved. Utility Model Content
