Is ejected from the transition chamber 23 at high pressure and diffuses in the outlet chamber 31. This causes a rapid pressure drop, and numerous fine cavitation bubbles are generated in the water flow in the water outlet chamber 31 by the boiling phenomenon. At this time, if the diameter of the inlet side of the water inlet chamber 22 is larger than the diameter of the outlet side of the water outlet chamber 31 and the axial dimension of the water inlet chamber 22 is shorter than the water outlet chamber 31, the water flow is ejected at high pressure through the rapidly reduced opening, and thus a large pressure difference is generated to effectively generate cavitation bubbles.

In addition, at the water outlet end of the micro-nano bubble water generating device 10, a second water pump 108 is externally connected through a water inlet pipe 107, then the water outlet end of the second water pump 108 is connected with a water outlet pipe 109, and the water outlet end is connected with a corresponding cleaning device (in the embodiment, the cleaning device is a hair washing machine 110) through the water outlet pipe 109;
