In addition, the auxiliary pressure relief assembly 22 is used to assist the cooking appliance in releasing steam, thereby regulating the internal pressure of the cooking appliance. In the pressure regulating state, the auxiliary pressure relief assembly 22 blocks the auxiliary steam outlet 24 of the cooking appliance from being conducted to the outside, and the solenoid assembly 18 drives the safety switch assembly 16 to move, so that steam in the cooking appliance is exhausted through the steam outlet 144. In the natural state or when the circumstances such as the outage take place, no effect of power between solenoid coil subassembly 18 and the safety switch subassembly 16, consequently safety switch subassembly 16 shutoff steam outlet 144 under self gravity, and supplementary pressure release subassembly 22 opens supplementary steam outlet 24, make supplementary steam outlet 24 and external world switch on, thereby make the steam in the cooking utensil release to the external world through supplementary steam outlet 24, and then adjust cooking utensil internal pressure, when the cooking utensil meets the circumstances of outage suddenly, safety switch subassembly 16 shutoff cooking utensil's steam outlet 144, the unable circumstances of releasing of cooking utensil internal pressure takes place.
