[0036] Working principle: When making delicious food with an electric pressure cooker in daily use, generally, the ingredients are washed and then placed into the inner pot 4 inside the main body 1 of the electric pressure cooker. Then, the pot lid 5 is covered, so that the first sealing ring 22 is sleeved and closely attached to the outer surface of one end of the main body 1 of the electric pressure cooker along with the pot lid 5. At the same time, the second sealing ring 26 will abut against one side of the main body 1 of the electric pressure cooker, sealing the inner walls between the main body 1 of the electric pressure cooker and the pot lid 5, performing double sealing on it. Then, the power cord is plugged into the socket to connect to the power supply for use. When the first sealing ring 22 and the second sealing ring 26 age after a long time of use or after being placed unused for too long, after covering the pot lid 5, one can manually hold the screwing block 29 and screw the threaded rod 24 in the threaded hole 23 to a certain number of turns, driving the extrusion frame 25 and the limiting block 27 to slide downward along the inner walls of the sliding groove 21 and the limiting groove 28 respectively, extruding the second sealing ring 26, making one side of it closely attached to one side of the first sealing ring 22 and one side of the main body 1 of the electric pressure cooker, making it not easy to generate gaps, avoiding affecting the use of the electric pressure cooker body, and at the same time reducing the frequency of replacing the sealing ring, facilitating daily use.

[0037] When the second sealing ring 26 is severely damaged and cannot be used, the clamping block 33 can be rotated to a certain angle in the circular groove 31 and the clamping hole 32, making one end of it move away from the magnet block 35 and align with the clamping hole 32, and then pulling it outwards, the clamping block 33 can be disassembled from the extrusion frame 25 and the second sealing ring 26. At the same time, the second sealing ring 26 can be disassembled from the extrusion frame 25, facilitating its replacement and maintenance. Similarly, the replaced second sealing ring 26 can be snapped into the inner wall of the sliding groove 21, and then the clamping block 33 can be used to fix it on the extrusion frame 25 for use.
