[0035] Brief description of the resetting process of the exhaust valve 3 of the electric pressure cooker.

[0036] When cooking is finished, the pot body 2 is in a high pressure state, so that the pot cover 1 cannot rotate to the unlocked position. At this time, the user can use the manual part 42 to move the key block 41 from the first position to the second position, that is, the trigger part 43 of the key block 41 lifts the exhaust valve 3 to exhaust, so that the pressure in the pot body 2 drops to a safe level, and the pot cover 1 can rotate. At the same time, the pressing block 44 of the key block 41 approaches the movable column 62, and the second guide surface 440 and the first guide surface 621 contact and abut against each other.

[0037] The pot cover 1 rotates to the unlocked position, when the third guide surface 622 at the bottom of the movable column 62 contacts and abuts against the fourth guide surface 51. The fourth guide surface 51 moves the movable column 62 upward and compresses the spring 63. The movable column 62 moves upward to move the key block 41 to the first position until the bottom of the movable column 62 moves to the top surface of the top block 5 via the fourth guide surface 51. The movable column 62 moves upward to move the key block 41 to the first position. At the same time, the triggering portion 43 moves away from the end of the seesaw 82. Under the action of the gravity of the exhaust valve 3, the seesaw 82 flips downward and resets, and the exhaust valve 3 is in the closed state again. In this way, when the pot cover 1 is turned again, there is no need to manually reset the control switch 4 to close the exhaust valve 3.
