Description

Technical Field

[0001] The utility model relates to the technical field of pots, in particular to an opening and closing structure of a pot cover. Background Art

[0002] In daily cooking, the use of pot lids is indispensable. The existing pot lid opening and closing structures are often designed without considering the user's convenience and safety. Some pot lids may have safety hazards when opening and closing. For example, if the user heats the pressure cooker without closing the lid properly, the pot lid may suddenly pop open due to excessive pressure, which may cause harm to the user.

[0003] In order to solve the above problems, some improved pot lid opening and closing structures have appeared in the industry, which improve the sealing and operating convenience of the pot lid by adding various locking structures and other components. However, these improved structures are often more complicated in design, increasing the manufacturing cost and maintenance difficulty, and in actual use, there may still be problems such as not smooth enough operation and being too complicated.
