As shown in fig. 1 to 4 and 6, the pressure cooking appliance includes: pot cover 10, pressure limiting valve 20, electromagnetic structure 40 and manual operation piece 50. The cooker lid 10 includes a cooker lid body 11 and an inner lid 12 located in the cooker lid body 11, and the inner lid 12 is provided with an exhaust passage 121. The pressure limiting valve 20 is disposed at the exhaust passage 121. The electromagnetic structure 40 is arranged on the cooker lid 10, and the pressure limiting valve 20 can open the exhaust passage 121 under the condition that the electromagnetic structure 40 is electrified. The manual operation member 50 is disposed on the lid 10, and the manual operation member 50 can cooperate with the pressure limiting valve 20 to open the exhaust passage 121 under an external force.

By applying the technical scheme of the first embodiment, the pressure limiting valve 20 can be controlled to exhaust air through the electromagnetic structure 40 in the cooking process of the pressure cooking appliance, so that the purpose of automatic exhaust is achieved. When the pressure cooking appliance is cooked and needs to be opened quickly, a user can manually operate the manual operation part 50 to enable the exhaust channel 121 to be opened continuously, so that the time for opening the cooker cover is shortened, and the use experience of the user is improved.

In addition, the wire of the electromagnet of the electric pressure cooker in the prior art needs to be connected with the control panel in the cooker body after passing through the pivot. With the increase of the times of opening and closing the cover, the conducting wire may be broken due to fatigue, so that the electric magnet cannot be electrified to realize air exhaust, and the safety of the electric pressure cooker is poor. By applying the technical scheme of the first embodiment, even if the lead of the electromagnetic structure 40 is broken due to fatigue, the user can perform manual air exhaust through the manual operation part 50, so that the pressure in the pressure cooking appliance is reduced, and the safety of the pressure cooking appliance is ensured.

As shown in fig. 1 to 4, 6 and 7, in the first embodiment, the pressure cooking appliance further includes a movable member 30, the movable member 30 is movably or pivotably disposed on the lid body 11, the movable member 30 is capable of cooperating with the pressure limiting valve 20, and the movable member 30 can be driven to move when the electromagnetic structure 40 is energized and when the manual operation member 50 is subjected to an external force. That is, the electromagnetic structure 40 and the manual operation member 50 cooperate with the same movable member 30 to drive the pressure limiting valve 20 to move, and the structure can effectively reduce the number of parts, thereby reducing the production cost and saving the space. Of course, in other embodiments not shown in the figures, the electromagnetic structure 40 and the manual operating member 50 can also actuate the movement of the pressure limiting valve through two independent moving parts. Alternatively, in another embodiment not shown in the figures, one of the electromagnetic structure 40 and the manual operator 50 cooperates with a movable element, the other of the electromagnetic structure 40 and the manual operator 50 directly actuating the movement of the pressure limiting valve.

As shown in fig. 1 to 4, 6 and 7, in the first embodiment, the movable member 30 is a lever pivotally disposed on the lid body 11, one end of the lever is located below the pressure limiting valve 20, and the electromagnetic structure 40 and the manual operating member 50 can drive the lever to rotate. As the lever rotates, the end of the lever located below the pressure limiting valve 20 can gradually move towards the pressure limiting valve 20 and lift the pressure limiting valve 20 upwards to open the exhaust passage. The structure is simple and easy to realize.

As shown in fig. 1 to 4, 6 and 7, in the first embodiment, the lever comprises a first rod segment 31 on one side of its pivot (L in fig. 7) and a second rod segment 32 on the other side of the pivot, the end of the first rod segment 31 is located below the pressure limiting valve 20, and the electromagnetic structure 40 and the manual operating member 50 can be engaged with the second rod segment 32. In particular, the above-mentioned electromagnetic structure 40 and the manual operator 50 are able to exert a downward force on the second rod segment 32, so as to gradually move the end of the lever located below the pressure limiting valve 20 upwards and eventually lift the latter. The structure is simple, and the assembly is convenient. Of course, in other embodiments not shown in the figures, the manual operator is capable of applying a downward force to the second pole segment and the electromagnetic structure is capable of applying an upward force to the first pole segment. The structure also enables one end of the lever, which is positioned below the pressure limiting valve, to gradually move towards the pressure limiting valve so as to lift the pressure limiting valve.

It should be noted that the electromagnet structure may be disposed above the first pole segment or below the first pole segment if the electromagnet structure exerts an upward force on the first pole segment. If the electromagnetic structure is arranged above the first rod section, the electromagnetic structure is attracted to the first rod section after being electrified. If the electromagnetic structure is located below the first pole segment, the direction of the current is changed, so that the polarity of the electromagnetic structure is changed after the electromagnetic structure is electrified and the electromagnetic structure is repelled from the first pole segment.

As shown in fig. 2 and 3, in the first embodiment, the electromagnetic structure 40 is located below the second pole segment 32, and the manual operating member 50 is located above the second pole segment 32. The structure is simple and easy to assemble.

As the lever is rotated, the lever can gradually lift the pressure limiting valve 20 to open the exhaust passage for exhaust. When the pressure cooking appliance is finished and needs to be opened quickly, the user can press the button downwards, and the button is abutted with the second rod section 32 to enable the lever to rotate anticlockwise as shown in the drawing. As the lever is rotated, the lever can also gradually raise the pressure limiting valve 20 to open the exhaust passage for exhaust.

As shown in fig. 1 to 3, in the first embodiment, an elastic return structure 60 is disposed between the groove bottom 115 of the first accommodating recess 113 and the manual operation piece body 51. When the user is not applying downward pressure to the manual operation member body 51, the manual operation member can return to the initial position under the effect of the elastic return force of the elastic return structure 60, so that the manual return of the user is avoided, and the use experience of the user is improved.

As shown in fig. 3 and 8, in the first embodiment, the manual operation device body 51 further includes a limit buckle 53 disposed below the guide side wall 512 and extending downward, a bayonet matched with a hook of the limit buckle 53 is disposed on the groove bottom 115 of the first accommodation groove 113, and the hook is in abutting fit with the bayonet to prevent the manual operation device 50 from being released from the first accommodation groove 113.
