When the air pressure in the cooking vessel is reduced, the stopper rod 234 falls back with the valve assembly 23 and is disengaged from the limiting hole 31, and at this time, the control assembly 3 can be rotated relative to the lid body 1 to open the vessel lid.

Through the design, when the cooking container is in a higher pressure state, the container cover cannot be opened, so that the safety of the cooking container can be improved, and the practical use requirement is met.

As shown in fig. 7, 8, 9, and 10, in one possible embodiment, the limiting hole 31 includes a first hole section 311 and a second hole section 312 that are communicated with each other, the first hole section 311 and the second hole section 312 are disposed along the circumferential direction of the container cover, and the cross-sectional area of the first hole section 311 is larger than the cross-sectional area of the second hole section 312. The stopper rod 234 has a first body portion 234a and a second body portion 234b, the first body portion 234a having a cross-sectional area smaller than the cross-sectional area of the second body portion 234b and the cross-sectional area of the second bore section 312, the second body portion 234b having a cross-sectional area larger than the cross-sectional area of the second bore section 312 and smaller than the cross-sectional area of the first bore section 311. The first body 234a and the second body 234b are disposed in this order in the thickness direction of the container cover, and the first body 234a is located above the second body 234 b.

When the control assembly 3 is in the locked state, at least a portion of the second body portion 234b extends into the second bore section 312.

The pressure inside the cooking vessel is high and there is a risk of opening the lid. In the solution provided in the present embodiment, under the influence of the pressure increase inside the cooking vessel, the push-stop rod 234 rises along with the valve assembly 23 and extends into the second main body portion 234b of the second hole section 312 to extend into the second hole section 312 to limit the rotation of the control assembly 3 relative to the lid body 1, so that the user cannot rotate the control assembly 3 to open the vessel lid, thereby being beneficial to improving the safety.

When the control assembly 3 is not in the locked state, at this time, the internal pressure of the cooking vessel is increased, the valve assembly 23 is lifted, the first body portion 234a of the stopper rod 234 can extend into the first hole section 311, and since the sectional area of the second body portion 234b is larger than that of the first hole section 311, the second body portion 234b abuts against the control assembly 3 in the thickness direction of the vessel cover to limit the valve assembly 23 to continue to lift, and a gap is provided between the third limit portion 231c located at one end of the valve assembly 23 near the filter 22 and the first limit portion 211.

Because the second main body 234b cannot extend into the first hole 311, the valve assembly 23 cannot further rise, the safety valve 2 cannot be closed, and two opposite sides of the container cover can be communicated through the safety valve 2, that is, the inside and the outside of the cooking container can be communicated, so that the condition that the pressure of the cooking container is high when the container cover is unlocked can be reduced, and the safety of the cooking container can be improved.

As shown in fig. 8, in one possible embodiment, when the third limit portion 231c abuts against the first limit portion 211, a gap is provided between the second main body portion 234b of the stopper rod 234 and the fourth limit portion 32 of the control unit 3 in the thickness direction of the container cover.

Such a design is used to limit the positions of the stopper rod 234 and the valve assembly 23 by the fourth limiting part 32 when the internal pressure of the cooking vessel exceeds a preset pressure range, thereby reducing the possibility of the valve assembly 23 being detached from the safety valve 2.
