Description

Technical Field

[0001] This utility model relates to the field of cooking utensil technology, and in particular to a pressure cooker lid exhaust structure. Background Technology

[0002] After the pressure cooker finishes cooking, the user needs to manually pull up the pressure relief valve on the lid. To prevent users from being burned by the high-temperature steam released during the pressure cooker's pressure relief process and to improve safety, modern pressure cookers usually have the pressure relief switch and the pressure relief valve set at a certain distance apart.

[0003] For example, Chinese utility model patent CN212015295U discloses a pressure cooker exhaust structure and a pressure cooker. The lever has a lifting end and a pressure-receiving end. The lifting end is driven by a pressure relief valve, and the pressure-receiving end is driven by a knob assembly. During rotation, the knob assembly can press downwards against the pressure-receiving end, causing the lifting end to swing upwards until it lifts the pressure relief valve. The problems with the prior art are: the pressure-receiving inclined surface of the knob assembly easily gets stuck on the lever during rotation, and the fixing structure of the knob assembly is relatively simple, making the knob prone to falling off, and lacking durability and smooth operation.

[0004] Therefore, existing technologies need to be improved. Utility Model Content
