Abstract
The invention discloses an electric pressure cooker with an improved pressure anti-uncapping device. The electric pressure cooker with the improved pressure anti-uncapping device comprises a cooker cover, a sealing ring, a cooker body or a middle cooker and the pressure anti-uncapping device, wherein the sealing ring is arranged on the cooker cover and the pressure anti-uncapping device is arranged on the cooker cover. The pressure anti-capping device comprises a hollow base, a fastening nut, a floater, a pressure spring, a valve core and a warping plate, wherein one end of the warping plate is the gravity reset end, the other end of the warping plate is provided with a buckling hook. Buckling plates are connected to the cooker cover in a pivoted mode. The top of a guiding post of the floater is matched with one side, provided with the gravity reset end, of the warping plate. When pressure does not exist in the cooker, the gravity reset end of the warping plate is attached to a top plate of the cooker cover. When pressure exists in the cooker, the buckling hook of the warping plate penetrates through a guiding hole to be embedded into a clamping groove which is formed in the middle of the lower buckling plate in the circumferential direction. When pressure exists in the cooker, the cooker cover cannot rotate, and a user can press the warping plate to enable the floater to move downwards to release pressure. After pressure is released, the cooker cover and the cooker body can be separated. Compared with the prior art, the electric pressure cooker with the improved pressure anti-uncapping device is simple in structure and high in reliability.
