[0002] As people's requirements for drinking water quality increase, water treatment technology continues to develop. There are various ways to produce bottled water on the market. Many small bottled water plants use manual operations in the cleaning, sterilization and filling of water barrels.

[0032] Specifically, the electromagnetic valve 51 can be controlled manually or automatically by the water filling machine to adapt to different application scenarios.

[0033] In other embodiments, the second delivery pipe 52 is configured as a spiral tube, which can make the pressure at the output end of the second delivery pipe 52 lower than the pressure inside the pipe, thereby preventing the liquid in the second delivery pipe 52 from overflowing and backflowing.

[0034] Specifically, in order to ensure that the liquid sprayed by the second nozzle 54 can flow smoothly into the clean water bucket, the diameter of the second nozzle 54 is smaller than the diameter of the connecting pipe 25 .
