[0042] In some optional embodiments of the first aspect of the utility model, the inner cover 20 is provided with a second convex step 23 extending outwardly, and the lower end of the outer cover 10 abuts against the outer edge of the second convex step 23. Specifically, the second convex step 23 is arranged on the inner cover 20 and extends in the opposite direction of the buckle with the pot body 2, that is, the lower part of the inner cover 20 extends outwardly. It should be noted that the inner cover 20 and the outer cover 10 both comprise a main body arranged on the upper end of the pot body and a lower part arranged around the main body for buckling, and the second convex step 23 herein is the lower part extending outwardly.
[0043] The second convex step 23 is arranged to form a gap between the inner cover 20 and the outer cover, so as to form a heat insulation space under the action of the second sealing part 32. Meanwhile, the lower end of the outer cover 10 abuts against the outer edge of the second convex step 23, which facilitates the disassembly of the outer cover 10 and the inner cover 20 and facilitates the subsequent cleaning of the pot cover assembly 1 and the like.

Specifically, the first snap-fit structure 41 and the second snap-fit structure 42 can be a protrusion and a groove, or a wedge-shaped protrusion and a wedge-shaped groove, or a rotating buckle and a socket. The first snap-fit structure 41 and the second snap-fit structure 42 are preferably a rotating buckle snap-fit structure, which has high snap-fit force and stability. After snap-fitting, the rotating buckle is not easy to loosen, which can effectively prevent the outer cover 10 from being accidentally opened. This structure is suitable for cooking utensils that require high sealing performance. Furthermore, in order to facilitate the snap-fitting of the first snap-fit structure 41 and the second snap-fit structure 42, the pot cover assembly 1 is further provided with a positioning member 12 for positioning the first snap-fit structure 41 and / or the second snap-fit structure 42. For example, the positioning member 12 can be a mark arranged on the outer surface of the outer cover 10 to form the positioning member 12, or the positioning member 12 can be a positioning baffle arranged inside the outer cover 10 and corresponding to the position of the second snap-fit structure 42, or the positioning member 12 can be a positioning mark arranged on the inner cover 20 and corresponding to the first snap-fit structure 41.
