Pressure cooker and its pressure regulating device

Abstract

The invention discloses a pressure cooker and a pressure adjusting device thereof. The pressure cooker comprises a cooker body, a cooker cover and a mounting seat. The pressure adjusting device is arranged on the cooker cover and comprises an air release valve, a magnetic part, an operation key and a self-locking part. The air release valve consists of a valve body and a valve core, the valve body is connected onto the valve core, two ends of the valve core penetrate through the cooker cover and the mounting seat respectively, and a steel part is arranged on the valve body; the magnetic part is movably axially arranged on the valve core; the operation key is movably arranged on the cooker cover and penetrates through the mounting seat, and the operation key drives the magnetic part to move downwards when touched; the self-locking part is arranged on the cooker cover and used for locking the operation key after the operation key is touched. The pressure adjusting device of the pressure cooker is capable of adjusting the pressure in the cooker body to meet various food cooking requirements, high in reliability, simple in structure and low in cost.

Description

Technical field [0001] The invention relates to the field of household appliances, and in particular to a pressure regulating device for a pressure cooker and a pressure cooker with the same. Background technique [0002] Electric pressure cookers are popular with consumers for their automatic cooking. However, most electric pressure cookers currently use a gravity pressure limiting valve with a single pressure limiting value, which cannot be adjusted with the needs of food, and can only achieve a single pressure control, which cannot meet the multiple needs of consumers. [0003] Existing pressure cookers also use solenoid valves to push pressure limiting valves to achieve pressure adjustment. However, this technology can only be used in intelligently controlled high-end electric pressure cooker products, and the product cost is high. Summary of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end...

Problems solved by technology

However, most electric pressure cookers currently use a gravity pressure limiting valve with a single pressure limit, which cannot be adjusted according to the needs of food, and can only achieve a single pressure control, which cannot meet the various needs of consumers.

[0003] Existing pressure cookers also use a solenoid valve to push the pressure limiting valve to achieve pressure regulation. However, this technology can only be used in high-end electric pressure cooker products with intelligent control, and the product cost is high.
