Elasticity supporting mechanism of automatic electric pressure cooker

The utility model relates to an elasticity supporting mechanism of automatic electric pressure cooker which is composed of a spring bearer plate and more than two spring pieces, all the spring pieces are in arc shape and overlapped together, and the spring bearer plate is buckled on the spring pieces. The utility model is fixed on the bottom flat of the inner cover of the automatic electrical pressure cooker by the spring bearer plate when in use, and the lower drive rod of the thermal tray is pressed over the spring bearer plate of the overlapped spring pieces. The compression stroke can be enlarged since the utility model is adopted the overlapped structure of the arc shaped spring pieces more than two, and the purpose to reach any size of the compression stroke is realized. The linearity of the deformation is good, the reset precision is high, the deformation is small, the permanent deformation is avoided, and the purpose of the accurate controlled pressure can be reached after the utility model is depressurized. Meanwhile, the utility model has features of safety, reliability, simple preparing process, and reduction of production cost.
