Abstract
A pressure cooker comprises a main body, a lid assembly, and an open-prevention assembly disposed on the lid assembly. The main body comprises a cooker rim and a cooker tooth extending therefrom, the open-prevention assembly comprises an open-prevention sliding block and a float device disposed on the lid assembly. With no pressure in the cooking chamber, rotating the lid will cause sliding movements of the open-prevention sliding block. With pressure in the cooking chamber, the float device will rise to prevent the open-prevention sliding block from sliding, thereby preventing the rotation of the lid. The open-prevention assembly comprises a locking sliding block coupled to the open-prevention sliding block. When a forced opening of the lid causes a deformation of the open-prevention sliding block, the locking sliding block lockingly engages the cooker tooth to prevent lid rotation, thereby ensuring safe use of the cooker.
