[0025] In summary, as Figures 1-3 As shown, the cavitation jet underwater cleaning device first sends water from the water tank 1 into the delivery cylinder 4 through the pump 601 and the water pipe 602.

[0027] During the cleaning process, when the water flow velocity increases to a certain level and the local absolute pressure is lower than the saturated vapor pressure at the local temperature, the air dissolved in the water will be released, forming many tiny cavitation bubbles. At the same time, the first cavitation nozzle 12 and the second cavitation nozzle 17, through their special structure and internal flow channels, make the water flow form a local low-pressure zone inside the nozzle, thereby promoting the generation of cavitation bubbles until they approach the surface being cleaned or cut and rupture due to obstruction.
