[0023] The regulating assembly is installed in the regulating valve chamber 74. When the regulating assembly is not under pressure, the regulating assembly is close to the port of the pressure relief channel 73. When the regulating assembly is under pressure, the regulating assembly is away from the port of the pressure relief channel 73.

[0024] The lower brewing assembly 8 is installed at the lower part of the upper brewing assembly 7, and a brewing chamber 82 is provided in the lower brewing assembly 8, and the brewing chamber 82 is connected to the lower part of the water inlet channel 71; and

[0025] The lower cover 9 is installed at the lower part of the lower brewing assembly 8 so as to receive the liquid flowing out of the brewing chamber 82.

[0026] During operation, when the pressure is normal, water passes through the water tank 3, the water pump 5, the water inlet channel 71 and the brewing chamber 82 in sequence to make coffee, and the regulating component approaches and blocks the port of the pressure relief channel 73; when the pressure is too high, water passes through the water tank 3, the water pump 5, the water inlet channel 71 and the brewing chamber 82 in sequence to make coffee, and because the water pressure is too high, the water pushes the regulating component to move, and the regulating component does not block the port of the pressure relief channel 73, so that the water passes through the water inlet channel 71, the pressure relief channel 73, the regulating valve chamber 74 and the pressure relief port 72 and then returns to the water tank 3 to relieve the pressure.

[0027] In this embodiment, a lower filter screen 83 is further included. The lower filter screen 83 is located at the lower part of the brewing chamber 82 to filter the liquid flowing out of the brewing chamber 82 .
