The opening stopping mechanism is positioned above the inner pot cover 30 and is provided with an opening stopping hole; the safety valve 40 is movably disposed on the inner pot cover 30, and when the cooking appliance is in a non-operating state, the safety valve 40 is located below the stop hole, when the cooking appliance is in an operating state, the safety valve 40 is raised into the opening stopping hole to stop the upper cover assembly 10 from being opened, the safety valve 40 has a receiving chamber 41, a top vent structure 42 communicating with the receiving chamber 41 and a bottom communication port 43, the safety valve 40 includes a valve body 44 and a valve core 45, the valve core 45 is movably disposed in the accommodating cavity 41 and can block the bottom communicating opening 43, the valve core 45 has a first magnetic steel 451, the valve body 44 has a second magnetic steel 441 matched with the first magnetic steel 451, the first magnetic steel 451 is matched with the second magnetic steel 441 to enable the valve core 45 to keep a state of blocking the bottom communicating opening 43, and the valve core 45 is jacked up to be separated from the bottom communicating opening 43 until the pressure in the cooker body assembly 20 rises to be greater than the magnetic force between the first magnetic steel 451 and the second magnetic steel 441.

by providing the opening stopping mechanism on the upper cover assembly 10, the opening stopping mechanism can prevent a user from opening the upper cover assembly 10 when the cooking appliance is pressed to work, so that the user can be better protected. When there is no pressure or a small pressure inside the cooking appliance, the safety valve 40 is below the open stop hole and does not function as an open stop, so that the upper cover assembly can be opened. When the cooking utensil is pressed upwards, the safety valve 40 can rise to the opening stopping hole under the action of pressure in the pot, and stops the opening of the cover of a user by the opening stopping mechanism, so that the opening stopping function is realized, and the user can be well protected. The second magnetic steel 441 on the valve body 44 of the safety valve 40 and the first magnetic steel 451 on the valve core 45 are cooperatively arranged, so that the valve core 45 can stably block the bottom communicating port 43, and the cooking utensil can stably press upwards. During normal pressing operation, the valve core 45 will not be separated from the valve body 44, so that the cooking utensil can be stably and reliably pressed.

The first magnetic steel 451 and the second magnetic steel 441 are respectively arranged at the top of the valve core 45 and the top of the valve body 44, so that the bottom of the valve core 45 can block the bottom communication port 43 of the valve body 44, and the safety valve 40 can not leak air. The mutual repulsion of the first magnetic steel 451 and the second magnetic steel 441 means that the opposite surfaces of the first magnetic steel 451 and the second magnetic steel 441 are like magnetic poles.

in a specific embodiment not shown, the second magnetic steel 441 is located at the bottom of the valve body 44, the first magnetic steel 451 is located at the bottom of the valve core 45, and the first magnetic steel 451 and the second magnetic steel 441 are attracted to each other. The first magnetic steel 451 and the second magnetic steel 441 are respectively arranged at the bottoms of the valve core 45 and the valve body 44, so that the bottom of the valve core 45 can block the bottom communication port 43 of the valve body 44, and the safety valve 40 can not leak air. The first magnetic steel 451 and the second magnetic steel 441 are mutually attracted, which means that the opposite surfaces of the first magnetic steel 451 and the second magnetic steel 441 are unlike magnetic poles.

The utility model provides a relief valve 40 still includes backstop structure, and backstop structure sets up the motion of scurrying on top with backstop case 45 at valve body 44 to prevent that case 45 from deviating from in the valve body 44. The stop structure is arranged at the top of the valve body 44, and the stop structure can prevent the valve core 45 from being pushed out from the valve body 44 by the internal pressure when the internal pressure of the cooking appliance is far greater than the gravity of the valve core 45 and the magnetic force between the two magnetic steels, so as to keep the working stability of the safety valve 40.

It should be noted that the stop structure may be an additionally provided structural member, or may be a part of the existing safety valve.

Alternatively, the stop structure and the valve body 44 may be integrally injection molded; or may be additionally mounted to the top of the valve body 44. The second magnetic steel 441 may be disposed below the stopping structure or above the stopping structure, and the specific arrangement may be determined according to the use requirement of the cooking appliance.

As shown in fig. 2 to 6, a second magnetic steel 441 is provided as a stopper structure at the top of the valve body 44 to stop the upward movement of the valve core 45, thereby preventing the valve core 45 from being removed from the valve body 44.

The first sealing ring and the first mounting groove 443 are fitted to the lower surface of the inner lid 30 to seal a gap formed between the safety valve 40 and the inner lid 30 so that the inside of the cooking appliance can be pressed upward. The limiting rib 442 is provided to prevent the valve body 44 from being separated from the inner lid 30, which may cause the cooking device not to work normally.

It should be noted that in this embodiment, the limiting ribs 442 are two segments, and the two segments of the limiting ribs 442 extend along the axial direction of the valve body 44 and are spaced apart from each other to form a groove between the two segments of the limiting ribs 442, and the groove is configured to facilitate the installation of the valve body 44 on the inner lid 30.

As shown in fig. 4 to 6, the stopper rib 442 is located in the middle of the valve body 44. The middle limiting rib 442 can prevent the safety valve 40 from falling into the cooking utensil and prevent the pressure in the pot from pushing the cooking utensil out of the outer pot cover.

as shown in fig. 2 and 3, the accommodating chamber 41 has a reduced section 411 on a side close to the bottom communication port 43, and the second sealing ring 50 on the valve core 45 can be pressed and sealed on the top of the reduced section 411. The arrangement of the necking section 411 is that the valve core 45 falls back to the bottom communication port 43 to provide a guiding function, and the necking section 411 is matched with the valve core 45 in a stopping way to prevent the valve core 45 from falling out of the valve body 44.

The flange section 453 is for stopping engagement with the throat section 411, but the flange section 453 may also engage with a stopping structure to prevent the valve element 45 from being disengaged from the valve body 44. The second seal ring 50 blocks the bottom communicating port 43 to prevent the bottom communicating port 43 from leaking air. The second sealing ring 50 is installed at the second installation groove 455, and the second installation groove 455 can prevent the second sealing ring 50 from being separated from the valve core 45. Such a magnet is simple to manufacture, and the second magnet 441 is not easily mounted inside the top opening 46 of the valve body 44 due to its circular plate-like structure.

In an embodiment not shown, the top venting structure 42 is disposed on the top of the valve body 44, and the top venting structure 42 is communicated with the receiving cavity 41, so that when the valve core 45 is separated from the bottom communicating port 43, the top venting structure 42, the receiving cavity 41 and the bottom communicating port 43 form a venting channel to vent the high pressure gas in the pot.
