When the gas pressure in the cooker body can overcome the gravity of the pressure limiting valve body 21 and the balancing weight 22, the exhaust can be realized. Therefore, the structure can realize two working pressures and realize the function of multi-stage pressure regulation. In addition, by applying the technical scheme of the invention, the pressure cooking appliance comprises the first transmission piece 31 and the second transmission piece 32 which are matched with each other, and the structure has the following advantages: firstly, for the pressure cooking appliances with the same distance between the driving mechanism 50 and the pressure limiting valve 20, the transmission part is divided into two transmission parts, so that the length of each transmission part is smaller, thereby avoiding the phenomenon that the produced product is deformed, and further avoiding the interference between the transmission parts and the pressure limiting valve 20 when the transmission parts rotate; secondly, the transmission part is divided into a first transmission member and a second transmission member, so that the swing range of the second transmission member 32 can be larger under the condition that the occupied space of the transmission members is small.
