[0027] Specifically, the water delivery mechanism 8 includes a booster water pump 801 and a water outlet pipe 803 installed on the surface of the cold water tank 1. The water inlet end of the booster water pump 801 is connected to the cold water tank 1, and the water outlet end of the booster water pump 801 is installed with a water inlet pipe 802, and the other end of the water inlet pipe 802 is respectively connected to the water inlet valve 7, and the two ends of the water outlet pipe 803 are respectively connected to the cold water tank 1 and the water inlet valve 7.
