Description

Technical Field

[0001] The present invention relates to the technical field of pressure cooker accessories, and more particularly to a pressure cooker cover and a pressure cooker. Background Art

[0002] As a kitchen appliance, a pressure cooker mainly uses the physical phenomenon that the boiling point of liquid increases under higher air pressure to apply pressure to water, allowing the water to reach a higher temperature without boiling, thereby speeding up the efficiency of stewing food. In high-altitude areas, using a pressure cooker can avoid the problem of lowering the boiling point of water and making it difficult to cook food.

[0003] The main problem with pressure cookers currently on the market is that the lid and the pot body are locked by pressing a button, so when opening and closing the lid, the user needs to deliberately find the corresponding button to operate, which is inconvenient and the operating experience is poor. Therefore, the locking structure between the lid and the pot body needs further improvement and enhancement. Summary of the Invention

[0004] The present invention is intended to at least solve one of the technical problems existing in the prior art. For this reason, the present invention proposes a pressure cooker cover and a pressure cooker with simple structure, easy use and high safety.

[0006] A pressure cooker lid according to an embodiment of the present invention has at least the following beneficial effects: when the lid and the cooker body need to be locked, the handle is simply rotated, which drives the limit block upward via the threaded column, thereby compressing the elastic element and simultaneously driving the left and right locking plates upward. At this time, the hooks on the ends of the left and right locking plates can be engaged with the cooker body. The elastic element then provides a downward elastic force to the left and right locking plates, thereby locking the lid and the cooker body. When the lid and the cooker body need to be separated, the handle is simply rotated, which drives the limit block downward via the threaded column. At this time, the hooks on the ends of the left and right locking plates are released from the cooker body. This structure is simple, easy to operate, and highly safe.

[0007] According to some embodiments of the present invention, an exhaust valve is provided on the cover.

[0008] According to some embodiments of the present invention, a safety valve is provided on the cover.

[0009] According to some embodiments of the present invention, rotating shafts are provided on both sides of the “n”-shaped frame, and the left and right locking plates are overlapped on the rotating shafts.

[0010] According to some embodiments of the present invention, the rotating handle is a plum blossom-shaped handle.

[0011] According to some embodiments of the present invention, the elastic element is a spring or a spring.

[0012] According to some embodiments of the present invention, the left and right locking plates are elastic stainless steel plates.
