Fig. 1 shows an embodiment of the electric pressure cooker of the invention, which comprises a cooker body 10 and a cooker cover, wherein the cooker body 10 is used for containing food materials to be cooked, and a heating device is arranged in the cooker body 10. The pot cover comprises a cover body 20, a lock cover 30 and a swing rod 40, wherein the cover body 20 is arranged on the pot body 10 in a turnover manner. The locking cover 30 is rotatably arranged below the cover body 20, and the swing rod 40 is in driving connection with the locking cover 30. In use, the lock cover 30 can be driven to be buckled with or opened from the pot body 10 by rotating the swing rod 40. The lid further includes an opening stop lever 50, an opening stop slide bar 60, and an opening cover mechanism 70, the opening stop lever 50 being movably provided on the lid body 20 in a vertical direction, the opening stop lever 50 being moved upward when the pressure in the lid body 10 is greater than a predetermined value. The opening stop slide bar 60 is movably disposed on the cover 20 and connected with the swing link 40. When the pressure in the pot body 10 is smaller than a preset value, the opening stop slide bar 60 can move along with the swing bar 40 on a preset track, and when the pressure in the pot body 10 is larger than the preset value, the opening stop bar 50 is matched with the opening stop slide bar 60 to prevent the opening stop slide bar 60 from moving. The cover opening mechanism 70 is provided between the cover body 20 and the pot body 10, and the cover opening mechanism 70 has a locked state in which the pot cover is locked to the pot body 10, and an unlocked state in which the pot cover is released to allow the pot cover to be opened with respect to the pot body 10. The cover body 20 is also provided with a linkage slide bar mechanism 80, the linkage slide bar mechanism 80 is connected with the opening stop slide bar 60, and when the swing rod 40 drives the lock cover 30 to move, the opening stop slide bar 60 drives the linkage slide bar mechanism 80 to move, and the linkage slide bar mechanism 80 cooperates with the cover opening mechanism 70 to limit the cover opening mechanism 70 in a locking state.

When the technical scheme of the embodiment is applied, the pot cover is buckled firstly and then the swing rod 40 is operated to drive the lock cover 30 to be buckled with the pot body 10 when the electric pressure cooker is needed to cook. While the swing rod 40 drives the lock cover 30 to move, the swing rod 40 also drives the opening stop slide rod 60 to move on a preset track, and the opening stop slide rod 60 drives the linkage slide rod mechanism 80 to move to a position matched with the cover opening mechanism 70, so that the cover opening mechanism 70 is limited in a locking state. In the cooking process, after the pressure in the pot body 10 is greater than a preset value, the opening stop rod 50 is jacked, and the opening stop rod 50 is matched with the opening stop slide rod 60 to prevent the opening stop slide rod 60 from moving. During cooking, if a user wants to rotate the swing link 40 to open the locking lid 30, the swing link 40 cannot rotate because the opening stop slide bar 60 is restricted from moving by the opening stop bar 50, and if the user wants to operate the lid opening mechanism 70 to release the lid of the pot relative to the pot body 10, the lid opening mechanism 70 cannot be operated because the lid opening mechanism 70 is restricted in the locked state by the link slide bar mechanism 80. Therefore, when the pressure in the cooker is large, double anti-opening is realized, the safety performance of the electric pressure cooker is improved, and the use safety of a user is ensured.

After the cooking is finished, when the pressure in the pot 10 is less than a predetermined value, the opening stop lever 50 is separated from the opening stop slide bar 60. At this time, if the user operates the swing link 40 to open the locking cap 30, the limit of the opening stop lever 50 is not satisfied, and the swing link 40 can be rotated to open the locking cap 30. In this process, the opening stop slide bar 60 moves along with the swing rod 40 on a predetermined track to drive the linkage slide bar mechanism 80 to separate from the cover opening mechanism 70, so that the user can operate the cover opening mechanism 70 to open the cover 20 from the pot body 10.

As an alternative embodiment, the jack 61 is a long hole, and the protruding columns 814 are in abutting fit with two ends of the jack 61 to drive the linkage slide bar mechanism 80 to move. As shown in fig. 5 and 7, when the swing rod 40 drives the locking cover 30 to move, the convex column 814 passes through the idle stroke in the long hole and then is in abutting fit with two ends of the jack 61. In the technical solution of the present embodiment, since the actual movement stroke of the linkage slide bar mechanism 80 is smaller than the actual movement stroke of the opening stop slide bar 60, by setting the insertion hole 61 as a long hole, the movement stroke of the linkage slide bar mechanism 80 can be matched with the movement stroke of the opening stop slide bar 60. The actual movement stroke of the opening stop slide bar 60 is equal to the sum of the actual movement stroke of the linkage slide bar mechanism 80 and the length of the long hole.

As other alternative embodiments, the opening stop slide bar 60 may be provided with a protruding column 814, and the jack 61 is arranged on the linkage slide bar mechanism 80, so that the opening stop slide bar 60 can drive the linkage slide bar mechanism 80 to move through the cooperation of the protruding column 814 and the jack 61.
