It can be understood that the first driving member 311 can be engaged with the first pressure-bearing member 711 through a linkage mechanism, and when the first driving member 311 drives the caliper assembly 31 to be fastened on the pot body 200, the first driving member 311 drives the linkage mechanism to move, so that the linkage mechanism drives the first pressure-bearing member 711 to move.

It should be noted that when the lid 100 is in the open state, there is a small gap between the valve core mechanism 7123 and the valve housing 7122, so that the gas in the pot body 200 can be discharged through the gap. In addition, the state that the passage is communicated with the accommodating cavity of the pot body 200 does not cover the condition that a gap exists between the valve core mechanism 7123 and the valve shell 7122.

In order to facilitate the cleaning operation of the lid 100, the valve housing 7122 is detachably connected to the valve seat 7121, and the valve core mechanism 7123 is also detachable from the lid 100. Wherein the valve housing 7122 comprises: the annular part 7122a and an end cover part 7122b, the annular part 7122a is sleeved on the circumferential outer side of the valve seat 7121, the end cover part 7122b is connected at the inner side wall of the annular part 7122a and arranged in parallel with the first bearing part 711, namely, the end cover part 7122b is vertically arranged with the valve core mechanism 7123.

It can be understood that, as shown in fig. 31, the ring-shaped member 7122a is detachably sleeved on the valve seat 7121, such as screwed or clamped, and a sealing member (7129), such as a rubber gasket, is disposed at a position where the ring-shaped member 7122a is connected to the valve seat 7121, for preventing a gap from occurring at a position where the ring-shaped member 7122a is connected to the valve seat 7121, so as to achieve a sealing effect; the peripheral edge of the end cover 7122b is tightly attached to the inner side wall of the ring 7122a, so that gaps are avoided.

It should be noted that the first elastic member 7125 and the second elastic member 713 are both spiral springs, and the cross-sectional diameters of the two axial ends of the first elastic member 7125 are different.

As shown in fig. 24, the valve core 7124 is formed with a plurality of sheet portions 7127 spaced from each other in the circumferential direction, an abutting convex portion 7128 is formed at one end of each sheet portion 7127 away from the end cover 7122b, and one end of the first elastic member 7125 away from the end cover 7122b abuts against the abutting convex portions 7128 at the same time, so that the first elastic member 7125 is limited between the valve core 7124 and the end cover 7122 b.

when the cap opening mode is used as an initial state, when the knob seat 212 is rotated counterclockwise, the first caliper mechanism 312 and the second caliper mechanism 313 simultaneously clamp the first cap 11 with the pot body 200, the fourth support post 7311 moves in the elliptical arc section 3114b, the first driving member 311 drives the linkage member 731 to move toward the direction of the transmission member 72, the linkage member 731 drives the second rotating shaft 7323, the connecting shaft plate 7322 and the first rotating shaft 7321 to rotate counterclockwise based on the supporting convex portion 7312, and the first rotating shaft 7321 drives the transmission member 72 to gradually turn from a horizontal state to a vertical state; meanwhile, during the turning process of the transmission member 72, the transmission member 72 presses the first pressure-bearing member 711 to move toward the valve core member 7124, and drives the axial end portion of the valve core member 7124 far away from the transmission member 72 to far away from the end cover member 7122b, so that the channel is communicated with the accommodating cavity in the pot body 200, as shown in fig. 27 and 28.

In order to prevent safety accidents caused by the fact that a user opens the lid 100 when the air pressure inside the pot body 200 is too high, as shown in fig. 32, an opening stop mechanism 80 is arranged on the first lid 11 in a penetrating manner, the opening stop mechanism 80 can move axially relative to the first lid 11, and the opening stop mechanism 80 can cooperate with the fastener 30 to limit the fastener to move or rotate. Namely: stop opening mechanism 80 and can wear to establish on calliper subassembly 31, when pressure culinary art mode, stop opening mechanism 80 and cooperate in order to prevent calliper subassembly 31 action with calliper subassembly 31, and then can avoid the user to uncap under pressure culinary art mode.

A limit opening 314 opposite to the open-stop rod 81 is formed at the second connecting plate 3132 of the caliper assembly 31, so that when the air pressure inside the pot body 200 is too high, the open-stop rod 81 moves towards the limit opening 314 and is clamped with the second connecting plate 3132 to prevent the second connecting plate 3132 from moving, thereby achieving the purpose of limiting the opening.
