Wherein the hardness of the deformation portion 22 is between 55 and 65. If the hardness of the deformation part 22 is less than 55, when the pressure in the cooker does not reach the preset forced pressure relief pressure, the deformation part 22 may deform, resulting in the pressure in the cooker being reduced; if the hardness of the deformation portion 22 is greater than 65, when the pressure in the cooker reaches the preset forced pressure relief pressure, the deformation portion 22 may not be deformed normally, resulting in a problem of pressure relief failure. In the present embodiment, the thickness of the deformation portion 22 is inversely proportional to the hardness, and the thickness of the deformation portion 22 is 1mm and the hardness is between 55 and 65.
