Abstract
The utility model discloses a beverage brewing device which comprises a machine base (1), a first machine part (2) and a second machine part (3), when the second machine part (3) moves forwards to a limit position, the second machine part (3) and the first machine part (2) are mutually folded and limit an extraction chamber for containing a capsule (10), the second machine part (3) comprises an outer cup (31) and an inner cup (32), and inner cavities of the inner cup (32) and the outer cup (31) jointly limit a base part (301). The water cup is characterized in that the outer wall of the inner cup (32) is in sealing fit with the inner wall of the outer cup (31), so that a closed hydraulic cavity (302) is formed between the inner cup (32) and the outer cup (31), the outer cup (31) is provided with a first liquid inlet channel (311), and the inner cup (32) is provided with a second liquid inlet channel (321). Compared with the prior art, the beverage brewing device has the advantage that the seat part can be prevented from being expanded without additionally arranging a blocking device.
