In order to make the gap between the dielectric body and the outer electrode uniform and fix the inner electrode without shaking, it is a conventional practice to manually wind an insulating tape on the surface of the dielectric body according to a certain method, and fill the gap between the dielectric body and the outer electrode by the number of winding layers of the insulating tape. However, this fixing method has the following problems:

1. the thickness of the insulating tape is thinner, the thickness is generally 0.1-0.2 mm, if the gap between the dielectric body and the outer electrode is larger, if the gap is larger than 1.0mm, a plurality of layers of insulating tapes need to be wound, the number of wound layers is too large, and the production efficiency is lower; the adhesive effect is greatly reduced due to the fact that the insulating tape is too thick, and the insulating tape is easy to fall off.

2. After the ozone generating tube is used for a certain time, dust particles, trace oil stains and the like in the gas can be adsorbed on the inner electrode, the dielectric body and the outer electrode, and the inner electrode, the dielectric body and the outer electrode are maintained and cleaned by disassembling the ozone generating tube; when the dielectric body is maintained and cleaned, the insulating tape on the surface of the dielectric body can fall off; after the maintenance and cleaning, the insulation tape needs to be wound again, which is very inconvenient.
