Clamp type pressure cooker

Abstract

Provided is a clamp type pressure cooker. The clamp type pressure cooker comprises a cooker body and a cooker cover, wherein the cooker cover is provided with a pressure-limiting valve and a clamp assembly, the pressure-limiting valve can adjust pressure of the pressure cooker, the clamp assembly is used for locking the cooker cover and the cooker body, the clamp assembly comprises at least two clamps capable of clamping the cooker cover and the edge of the cooker body, the clamps are connected with a driving device, so that the clamps are located in a locking position for locking the cooker cover and the cooker body or a unlocking position for unlocking the cooker cover and the cooker body, and the cooker is characterized in that the driving device comprises a knob switch, a first drivingpart and a second driving part. The knob switch can simultaneously control the opening and closing of the clamps and pressure adjustment of the pressure-limiting valve, so that an one-key operation of cover opening and closing and pressure adjustment of the pressure cooker is achieved; the knob switch can perform the pressure adjustment on the pressure-limiting valve only after the clamps are located at locking gear positions, thereby preventing the pressure cooker from being directly used due to the fact that the clamps do not clamp the pressure cooker tightly; in the same way, only after the knob switch is rotated from a pressure adjustment gear position to the locking gear position, can the pressure-limiting valve perform venting, the cooker cover cannot be opened until the pressure inthe pressure cooker is released, and the use safety is improved.

Description

technical field [0001] The invention belongs to the technical field of kitchen cooking utensils, and in particular relates to a clamp type pressure cooker. Background technique [0002] Pressure cookers currently on the market mostly include screw-on pressure cookers and clamp-type pressure cookers, among which the clamp-type pressure cookers are favored because of the convenience of opening and closing lids. For example, the invention patent "clamp type pressure cooker" with the authorized announcement number CN104921592B discloses a clamp type pressure cooker, including a pot body and a pot cover, a seal is arranged between the pot body and the pot cover, and the upper surface of the pot cover has a The installation groove also includes: a transmission part, which is rotatably installed in the middle of the installation groove; two clamps are respectively arranged on both sides of the transmission part, and the clamp includes a clamp body and a clamp connecting plate fixed...

AI Technical Summary

Problems solved by technology

[0004] The existing clamp-type pressure cooker makes up for the difficulty of opening and closing the lid of the traditional screw-in pressure cooker, but it is not difficult to find that whether it is a screw-in pressure cooker or a clamp-type pressure cooker, the opening and closing operation of the pot body and the lid is a set of devices. , the pressure regulating operation of the pressure limiting valve is another set of devices

Especially the clamp...
