An upper cover 305 is installed on the inner tank body 302. The upper cover 305 is provided with a carbon dioxide gas nozzle 306, an atomizing nozzle 307, and a sparkling water outlet pipe 308. The output end of the cold water outlet pipe 304 is divided into two paths. One path is communicated with the cold water outlet, and the other path is communicated with the atomizing nozzle 307 through the booster pump 5. The output end of the sparkling water outlet pipe 308 is communicated with the sparkling water outlet. By providing a purified water outlet, a hot water outlet, a cold water outlet, and a sparkling water outlet, this multifunctional water dispenser has four functional modes of providing normal-temperature purified water, hot water, cold water, and sparkling water, thus realizing the function of multi-purpose in one machine. Among them, the cold water tank 3 includes an outer tank body 301 and an inner tank body 302. The outer tank body 301 is used to prepare cold water. The inner tank body 302 is provided with a carbon dioxide gas nozzle 306 for filling carbon dioxide gas and an atomizing nozzle 307 for filling cold water. The atomized cold water and the carbon dioxide gas are fully contacted and dissolved to prepare sparkling water. Compared with the double-tank structure that is mutually independent and separated in the prior art, it has the advantages of high integration, good compatibility, and small occupied space, can effectively reduce the volume of the water dispenser, and only one set of refrigeration system 4 can be used to refrigerate purified water and sparkling water, which can effectively reduce the production cost.
