The invention relates to a full-automatic beverage brewing machine, comprising a pot body and a power supply base, wherein the pot body comprises a heating cavity and a brewing cavity movably connected with the heating cavity, a circulating assembly is arranged between the brewing cavity and the heating cavity to jointly form a water loop. The circulating assembly comprises a water pump and a water circulation pipeline connected with the water pump. In the invention, the circulating assembly is additionally arranged to jointly form the water loop, and a gap is kept between the brewing cavity and the highest water level line MAX of the heating cavity, thus the heating cavity is separated from the brewing cavity, a brewed matter is ensured to be not in direct contact with the heating cavity in a water boiling process, and the brewed matter can be effectively prevented from releasing harmful ingredients after being soaked at high temperature for a long time; and the active ingredients of the brewed matter can be rapidly extracted, and the extraction concentration can be controlled, thus brewed beverage is applicable to the crowd with different tastes. By adopting the full-automatic beverage brewing machine, coffee and tea can be brewed, milk powder can be mixed, or a traditional Chinese medicine can be decocted, thus different beverages can be obtained; and the full-automatic beverage brewing machine has the characteristics of simple and reasonable structure, low cost, simplicity and convenience in operation and convenience in processing and production, multiple purposes of the machine can be achieved, and the practicability of a product is increased.
