[0027] The implementation principle of a pressure-dissolved gas high-concentration ozone contact device in the embodiment of the present application is as follows: when using the contact device, firstly, flowing high-pressure liquid is introduced into the body 1. After the high-pressure liquid flows rapidly through the blades 31, the flowing liquid drives the blades 31 to rotate. The rotation of the blades 31 drives the transmission shaft 32 to rotate around its own axis in the support ring 42, and the transmission shaft 32 drives the stirring rod 33 to rotate; when the transmission shaft 32 rotates, it drives the inner ring 62 to rotate synchronously. When the inner ring 62 rotates, the sealing strip 71 and the second magnet 732 of the inner ring 62 rotate relative to each other. At this time, the sealing strip 71 abuts against the wear-reducing balls 8, and the sealing strip 71 drives the wear-reducing balls 8 to roll between the two second magnets 732; at this time Ozone is transported to the body 1 through the delivery pipe 2. After passing through the air delivery cavity, the ozone gas flow enters the first air flow channel 321 through the air inlet 322, then enters the second air flow channel 331 of the stirring rod 33 through the first air flow channel 321, and finally is ejected from the jet hole 332 in the second air flow channel 331. The ejected bubbles are broken into small bubbles after encountering the breaking cone 101. The small bubbles are evenly mixed with the high-pressure liquid flowing through under the rotation of the stirring rod 33. The rotation of the stirring rod 33 allows the ozone transported by the delivery pipe 2 to quickly contact and mix with the liquid in the body 1, thereby increasing the contact area between ozone and liquid, thereby achieving the purpose of improving the dissolution efficiency of ozone in liquid.

After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
