When the pressure in the cooker rises to exceed the downward pressure exerted by the cooker cover, the pressing block and the carrier, the cooker cover, the pressing block and the carrier are jacked upwards, a gap is formed between the cooker cover and the annular bottom plane of the sealing ring, the gap is gradually increased along with the continuous rising of the pressure in the cooker, the cooker cover is synchronously raised, and when the pressure rises to the inner upper edge of the sealing ring, the inner diameter of the upper edge of the sealing ring is smaller than the outer diameter of the cooker cover, the upward force of the cooker cover drives the upper edge of the sealing ring to move upwards to enable the sealing ring to move upwards and deform, so that the annular opening and closing gap is opened and enlarged, as shown in figure 5. At the moment, overpressure steam which is blown out from the pot enters the annular unequal-diameter pipeline with the oval cross section through the opening and closing gap of the sealing ring, a part of steam is discharged through the sealing ring steam-liquid discharge pipe through the pipeline, a part of steam forms condensed water, and the condensed water flows to the lower sealing ring steam-liquid discharge pipe from high to low in the annular unequal-diameter pipeline with the oval cross section with the height difference and is discharged. After the overpressure steam is discharged and decompressed, the pressure in the cooker is reduced, the cooker cover falls back again and is pressed on the annular bottom plane measured in the sealing ring under the gravity action of the cooker cover, the pressing block and the carrier, the sealing ring is restored to the state before deformation, the annular opening gap is closed, and the cooker is in the sealing working state again, as shown in fig. 6. After the pressure in the cooker is increased for the next time, the cooker cover is pushed to rise, and the circulation process is repeated, so that the preset additional pressure applied by the pressing block is dynamically maintained in the cooker all the time, the cooking time of the food in the cooker is shortened, and the fuel consumption is reduced.
