Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and detailed description.
Examples
Referring to fig. 1 to 6, a safety device of a pressure cooker is shown, which includes a safety device 5, the pressure cooker includes a cooker body 1 and a pressure cover 2 covering the cooker body 1, and a pressure ring 3 for fastening or releasing the pressure cover 2 and the cooker body 1 is installed on the pressure cover 2; the outer edge of the pressure cover 2 is bent inwards to form an inward bent structure 21, a pot opening sealing ring 4 is arranged in the inward bent structure 21, the outer diameter of the pot opening sealing ring 4 is an embedded part 41, and the embedded part 41 is embedded in the inward bent structure 21; the safety device 5 is arranged on the cover edge of the pressure cover 2, when the pressure in the cooker exceeds a set value, the safety device 5 forces the cooker opening sealing ring 4 to deform and shift, and the safety device 5 is positioned below the pressure ring 3.
