Moving-cover type electric pressure cooker

[0029] Example: Take the 20 cm diameter of the inner pot 9 as an example. An aluminum plate with a thickness of about 2.5mm is used to stretch the inner pot 9 into shape, and a number of pressure relief grooves (such as 8) are uniformly arranged along the circumference on the inner side of the pot rim and above the sealing part of the sealing ring 8. The size of each pressure relief groove is: the radial direction of the inner pot 9 is about 4mm, the arc of the circumferential direction is about 5°, and the height dimension (the size extending from the pot along the plane downward) is also the height dimension of the pressure relief loop. It is directly related to the limit value of the highest pressure in the pot, and should be designed in conjunction with the height dimension of the sealing ring 8, the height dimension of the sealing part of the pot cover 1, and the displacement of the elastic element 2 to obtain the required pressure relief value. The sealing ring 8 is made of hig
