Optionally, the air inlet end of the air inlet pipe 820 may be communicated with the pipe body of the liquid inlet pipe 810, and communicated with the inlet end of the self-priming pump 300 through the liquid inlet pipe 810; when micro-nano bubble water is prepared, air entering the air inlet pipe 820 firstly enters the liquid inlet pipe 810 to be mixed with raw water in the liquid inlet pipe, and then the air and the raw water flow into the self-priming pump 300 together.
Specifically, in this embodiment, as shown in fig. 2 and fig. 3, the micro-nano bubble generating assembly 500 may include a gas mixing tank 510 and an aeration head 520, wherein the gas mixing tank 510 and the aeration head 520 are both installed on the second liquid outlet pipe 840, and the gas mixing tank 510 is located upstream of the aeration head 520. In a specific form of the micro-nano bubble generating assembly 500, a mixed fluid mixed and pressurized by the self-priming pump 300 firstly enters the gas mixing tank 510, and the mixed fluid is pressurized and dissolved in the gas mixing tank 510 and then is released by a pressure reducing structure in the gas mixing tank 510 to output bubble water with small particle size; and (3) the small-particle bubble water is outgassed again through the porous structure of the aeration head 520 and output to obtain the micro-nano bubble water. Specifically, the diameter of the bubbles in the micro-nano bubble water can be 200nm-50 μm.
