The existence of the thickness difference enables the limiting convex rib 3 and the mounting port 4 to realize the anti-falling limiting and the abrasion-free disassembly in a smaller size, so that the structural size of the pot port sealing ring can be smaller.

In one embodiment, the pot cover further comprises a surface cover, the surface cover is arranged outside the cover body 5, a limiting structure is arranged on the lower side or the inner side surface of the surface cover and is used for being matched with the limiting convex rib 3 to limit the falling-out of the limiting convex rib 3. In this embodiment, the limit structure on the cover may be a hole structure, the shape of the hole structure is similar to that of the mounting opening 4 on the cover body 5, the hole structure is located on the extension structure in the cover body and corresponds to the mounting opening 4 on the cover body 5, and the hole structure may be matched with the limit rib 3 to play a role in preventing the release of the sealing ring of the pot mouth. The limiting convex ribs 3 can be hooked on the hole structure of the face cover and can also be hooked on the edge of the mounting opening 4, so that a hooking limiting effect is formed.

The face cover can adopt plastic parts, the edge of the hole structure is smooth, and the limit ribs 3 can be prevented from being scratched while the limit fixing function is enhanced.

The size of the hole structure in the surface cover is smaller than the mounting opening 4 on the cover body 5, and the projection of the hole structure on the surface cover in the horizontal direction is positioned in the projection range of the mounting opening 4 of the cover body 5 in the horizontal direction.
