[0035] Referring to Figure 4 and Figure 5, an adsorbent 73 is provided between the sealing strip 71 and the insertion groove. The adsorbent 73 is used to fix the sealing strip 71 in the insertion groove. The adsorbent 73 includes a first magnet 731 and a second magnet 732.

[0037] The implementation principle of a pressure-dissolved air type high-concentration ozone contact device in an embodiment of the present application is as follows: When using the contact device, first, a flowing high-pressure liquid is introduced into the main body 1. After the fast-flowing high-pressure liquid passes 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 anti-friction ball 8, and the sealing strip 71 drives the anti-friction ball 8 to roll between the two second magnets 732; at this time, ozone is transported into the main body 1 through the delivery pipe 2. The ozone air flow enters the first air flow channel 321 through the air inlet hole 322 after passing through the air delivery cavity, and then enters the second air flow channel 331 of the stirring rod 33 through the first air flow channel 321, and finally sprays out from the air spraying holes 332 in the second air flow channel 331. The sprayed bubbles are broken into small bubbles when they encounter the breaking cone 101. The small bubbles are uniformly mixed with the flowing high-pressure liquid under the rotation of the stirring rod 33. By using the rotation of the stirring rod 33, the ozone transported by the delivery pipe 2 is quickly contacted and mixed with the liquid in the main body 1, increasing the contact area between the ozone and the liquid, thereby achieving the purpose of improving the dissolution efficiency of ozone in the liquid.

After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
