The high-pressure solenoid valve 421 is arranged in the installation cavity 81. The exhaust push rod 422 is slidingly connected to the high-pressure solenoid valve 421. The high-pressure solenoid valve 421 is used to drive the exhaust push rod 422 to move in a horizontal direction. A second ear edge 414 is provided on the outer wall of the high-pressure valve body 411. The high-pressure solenoid valve 421 drives the exhaust push rod 422 to move toward the direction of the high-pressure exhaust valve 41.

[0041] Reference Figure 5 The cooking utensil includes a second mounting bracket 7, which is connected to the inner bottom wall of the pot cover 2.

There are two second ear edges 414, and the two second ear edges 414 are respectively located on opposite sides of the high-pressure valve body 411, so that the exhaust push rod 422 can drive the second ear edge 414 and the high-pressure valve body 411 to move upward.

[0042] Reference Figure 2 The pot body 1 includes an outer pot 11 and an inner pot 12 , and the outer pot 11 is sleeved outside the inner pot 12 to protect the inner pot 12 .

[0043] Reference Figures 1 to 8When pressure-free full boiling cooking is required, the high-pressure solenoid valve 421 drives the exhaust push rod 422 to push the high-pressure valve body 411 to move upward, so that the high-pressure exhaust valve top cone 412 is separated from the high-pressure exhaust valve core 413, so that the steam in the inner pot 12 is discharged through the second exhaust passage 415 to achieve pressure-free full boiling cooking; when low-pressure full boiling cooking is required, the high-pressure exhaust valve 41 and the low-pressure exhaust valve 31 are both in a sealed state. When the pressure in the inner pot 12 reaches or exceeds the pressure that the low-pressure exhaust valve 31 can withstand, the steam in the inner pot 12 pushes up the low-pressure valve body 311, and the steam passes through the second exhaust passage 415. The steam is discharged through an exhaust passage 315, thereby realizing low-pressure full boiling cooking; when high-pressure full boiling cooking is required, the low-pressure solenoid valve 321 pushes the pressure push rod 322 to move toward the low-pressure steam exhaust valve 31, and the pressure push rod 322 presses against the first ear edge 314. At the same time, the spring applies downward pressure to the pressure push rod 322, so that the pressure that the low-pressure steam exhaust valve 31 can withstand is higher than that of the high-pressure steam exhaust valve 41. Both the low-pressure steam exhaust valve 31 and the high-pressure steam exhaust valve 41 are in a sealed state. When the pressure in the inner pot 12 reaches or exceeds the pressure that the high-pressure steam exhaust valve 41 can withstand, the high-pressure steam exhaust valve 41 opens.
