Sealed corona ozone generating tube

The utility model relates to a sealed corona ozone generating tube. Comprising a first sleeve, a first spring wire arranged in the first sleeve, a second sleeve arranged outside the first sleeve in a sleeving mode, a second spring wire arranged between the first sleeve and the second sleeve, two end covers arranged at the two ends of the second sleeve, an air inlet pipe and an air outlet pipe, wherein the air inlet pipe and the air outlet pipe are arranged on the two end covers respectively. And the two end covers are respectively communicated with an air inlet pipe and an air outlet pipe which are arranged on the end covers. According to the closed space formed by the ozone generator, the second sleeve and the end cover, no nitrogen participates in the ozone generation process, and no nitrogen oxide is generated; meanwhile, substances such as dust in the air are prevented from being adsorbed on the ozone generation pipe, so that the ozone yield is reduced, and the service life of the ozone generation pipe is
