When pressure cooking is performed, the second opening stop lever 53 is provided corresponding to the first opening stop lever 323, and both of them realize the opening stop function together. Specifically, when the pressure in the cooker is high, the second opening stop rod 53 is jacked up under the action of high-pressure gas so as to jack up the first opening stop rod 323; when the pressure release is completed, both the first opening stop bar 323 and the second opening stop bar 53 are dropped by gravity.

As shown in fig. 9, a second sleeve 3115 is disposed in the box structure 311, a sixth protruding edge 3116 is disposed on an inner surface of the second sleeve 3115, the first opening stop rod 323 is disposed through the second sleeve 3115, a third protruding edge 3231 is disposed on the first opening stop rod 323, when the first opening stop rod 323 and the box body are assembled, the first opening stop rod 323 penetrates into the second sleeve 3115 from top to bottom, the first opening stop rod 323 is suspended in the second sleeve 3115 under the action of the stop cooperation of the sixth protruding edge 3116 and the third protruding edge 3231, and then a sixth sealing member 327 is sleeved on a bottom end of the first opening stop rod 323, so that the first opening stop rod 323 is movably arranged in the second sleeve 3115 in a penetrating manner, and the first opening stop rod 323 can be prevented from being separated from the second sleeve 3115. In this embodiment, the upper end of the second sleeve 3115 protrudes upward from the top plate 3111, and before the pressure release is completed, when the user wants to open the cover forcibly, the upper end of the second sleeve 3115 can support the first open stop bar 323 effectively, so as to avoid the first open stop bar 323 from being deformed by a strong force.

As shown in fig. 9, the connection between the second opening stop rod 53 and the valve seat 52 is similar to the connection between the first opening stop rod 323 and the main body of the case, and will not be described again.

As shown in fig. 6, 7 and 9, the valve seat 52 is provided with a second flange 521, and the third seal 62 includes a second annular body portion 621 and a second flange 622 connected to a bottom end of the second annular body portion 621 and extending inward, the second flange 622 being interposed between the second flange 521 and the pressure cover 40. The fixing of the third sealing element 62 to the pressure cap 40 is achieved by sandwiching the second flange 622 between the second flange 521 and the pressure cap 40, with the advantage of a simple structure.

As shown in fig. 6, 7 and 9, the third sealing member 62 further includes a third sealing lip 623 connected to the upper end of the second annular body portion 621 and extending upward and inward, the third sealing lip 623 having a thickness less than the thickness of the second annular body portion 621. The thickness of the third sealing lip 623 is smaller than that of the second annular body 621, and when the pressure cover 40 is mounted on the cover body 10, the third sealing lip 623 is easily deformed inward by being pressed to be pressed against the lower surface of the bottom plate 312, ensuring the sealing effect.

In this embodiment, the thickness of the second annular body portion 621 is between 1.5mm and 2.5mm. Since the sealing requirement for the third seal 62 is relatively weak, setting the thickness of the second annular main body portion 621 small can reduce the material consumption of the third seal 62. Preferably, the thickness of the second annular body portion 621 may be 1.5mm, 2.0mm, or 2.5mm.

In this embodiment, each seal is made of a silicone material.
