Abstract: A gas-liquid mixing device of a beverage is provided. The gas-liquid mixing device has a container, a liquid inlet pipe, a gas inlet pipe and a liquid discharging pipe configured to discharge liquid, wherein the container is provided with a refrigeration evaporator; the container is further internally provided with a liquid precooling pipe; the liquid entering at the earliest enters the container through the liquid precooling pipe and is stored in the container and cooled by the refrigeration evaporator; the cooled liquid precools the liquid entering the liquid precooling pipe subsequently; the precooled liquid in the container is mixed and dissolved with entering gas; the container is further internally provided with a liquid molecule expander comprising a precooling liquid container inlet and a collision wall; the precooled liquid is ejected to the collision wall through the precooling liquid container inlet.

Abstract: A self-pressurization gas-liquid mixing device used for making a beverage is provided. The self-pressurization gas-liquid mixing device includes a container, a liquid inlet pipe configured to allow liquid to enter the container, a gas inlet pipe configured to allow gas to enter the container, and a liquid discharging pipe configured to discharge the liquid; a partition plate is arranged in the container to divide the container into a premixing chamber and a mixing chamber, the premixing chamber is arranged at the side of the liquid inlet pipe and the gas inlet pipe, the partition plate is provided with a plurality of premixing through holes, a mixing layer is further arranged between the mixing chamber and the liquid discharging pipe and includes a plurality of miniature pipes, and whisker holes which are opened and closed in one direction are formed in pipe walls of the miniature pipes.
