The utility model provides a gas mixer and a beverage dispenser, relates to the technical field of water-
gas mixing device, wherein the gas mixer comprises a tank body, a water inlet and a gas inlet are arranged on the tank body, a water inlet
pipe is arranged at the water inlet, one end of the water inlet
pipe extends into the tank body through the water inlet, and the other end of the water inlet
pipe extends into the tank body through the gas inlet. One end of the water inlet pipe, which is positioned in the tank body, is connected with a sealing cover, a water inlet hole is formed in the sealing cover, a torrent plate is arranged below the water inlet hole, and the torrent plate is used for being impacted by the jetted high-pressure
water flow so as to be splashed up to form water mist, so that the water mist is fully mixed with gas fed into the tank body through the gas inlet. The high-pressure
water flow impacts the torrent plate to form water mist, so that the contact area of water and gas is greatly increased, the dissolving efficiency of
carbon dioxide in water is improved, and compared with a traditional static mixing mode, the
mixing effect can be remarkably improved, and the quality of an output steam-water mixture is higher and closer to an expected standard.
