[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

[0042] The utility model provides a sealing structure for a high-voltage terminal of a high-reliability ozone generator, comprising a fixing piece, an intermediate piece and a fastener. Through the specific structural design of the fixing piece and the intermediate piece, before the fastener is locked with the fixing piece, the intermediate piece is first placed inside the fixing piece, and during the locking process, an inverted truncated cone-shaped axial channel inside the fixing piece provides a force that causes a deformation portion of the intermediate piece to deform, so that the through groove of the intermediate piece contracts inwardly, tightly holds the high-voltage terminal, and forms a sealing structure for the high-voltage terminal. In addition, during the locking process, the force gradually increases, and the tighter the hold, the better the sealing performance.

[0043] Furthermore, the fastener is provided with an abutment portion abutting against an end surface of the deformation portion at one end away from the column.

[0044] It can be seen from the above description that providing the abutting portion can better help the middle piece and the fixing piece to be in close contact, thereby improving the sealing performance.

[0045] Furthermore, the outer side wall of the deformation portion is used to contact the side wall of the axial channel of the first hollow cylinder, and the inclination of the outer side wall of the deformation portion is greater than the inclination of the side wall of the axial channel of the first hollow cylinder.

[0046] It can be seen from the above description that, through the above arrangement, an interference fit between the intermediate piece and the fixing piece is achieved, thereby meeting the sealing requirements.

[0047] Furthermore, an external thread is provided on the outer surface of the side wall of the first hollow cylinder, the fastener is a second hollow cylinder with one end open and the other end closed, the through hole is provided on the end surface of the closed end of the second hollow cylinder, and an internal thread matching the external thread is provided on the inner surface of the side wall of the second hollow cylinder.

[0048] It can be seen from the above description that the threaded connection between the fastener and the fixing member is achieved through the above design.

[0049] Furthermore, both end notches of the through slot have chamfered portions.

[0050] It can be seen from the above description that the above arrangement facilitates the assembly of the high voltage terminal.

[0051] Furthermore, the through hole is a circular hole, the column is a cylinder, and the diameter of the circular hole is between the diameter of the cylinder and the maximum diameter of the deformation portion.

[0052] It can be seen from the above description that through the above arrangement, the circular hole plays a limiting role.

[0053] Furthermore, one end of the first hollow cylinder is welded to the side wall of the ozone generator to form a seal.

[0054] It can be seen from the above description that, through the above arrangement, the first hollow cylinder and the side wall of the ozone generator also meet the sealing effect, thereby achieving the sealing requirement as a whole.
