At the same time, it avoids noise when placed or closed, and can improve the fit with the pot body when the lid is closed, improve the sealing, and avoid steam being discharged at an uncertain position to cause burns.

[0033] Specifically, a plurality of holes 11 are evenly distributed around the edge of the cover body 1, and the holes 11 are circular holes. The upper and lower ends of the holes 11 penetrate the upper bottom surface and the lower bottom surface of the cover body 1. In this embodiment, the hole diameter of the hole 11 is greater than or equal to 2 mm and less than or equal to 5 mm. At the same time, the angle between two adjacent holes 11 is greater than or equal to 3 degrees and less than or equal to 20 degrees, that is, the number of holes 11 is 18-120, which is used to improve the connection strength and reliability between the rubber ring 2 and the cover body 1 to avoid falling off, especially after long-term high-temperature use; refer to Figure 6 The rubber ring 2 includes an upper rubber layer 21, a lower rubber layer 22 and an outer rubber layer 23, wherein the upper rubber layer 21 is attached to the upper surface of the cover body 1, the lower rubber layer 22 is attached to the lower surface of the cover body 1, the outer rubber layer 23 is attached to the side wall of the cover body 1, and the upper end of the outer rubber layer 23 is connected to the upper rubber layer 21, and the lower end of the outer rubber layer 23 is connected to the lower rubber layer 22, forming a coating on the edge of the cover body 1. At the same time, a connecting column 24 is provided between the upper rubber layer 21 and the lower rubber layer 22, the upper end of the connecting column 24 is connected to the upper rubber layer 21, and the lower end is connected to the lower rubber layer 22, and the connecting column 24 is located in the hole body 11, which can greatly improve the connection strength between the rubber ring 2 and the cover body 1, avoid deformation and separation from the cover body after being heated and used for a long time, and greatly improve the reliability and service life of the use.

[0034] In this embodiment, the upper rubber layer 21, the lower rubber layer 22, the outer rubber layer 23 and the connecting column 24 are integrally formed at the edge of the cover body 1 by injection molding to form an integrated structure with high fit and strength and good use effect. The connecting column 24 fills the entire hole body 11, with high structural strength and connection strength and long service life; preferably, the top surface of the upper rubber layer 21 has a certain slope, with a compact structure and beautiful appearance; at the same time, the thickness of the outer rubber layer is greater than that of the upper rubber layer and the lower rubber layer, and the structural strength is high.

[0035] A limiting protrusion 25 is provided on the bottom surface of the lower rubber layer 22. The limiting protrusion 25 is annular and coaxial with the rubber ring 2, and is used for radial limiting when the cover is closed. The outer wall of the limiting protrusion 25 serves as a limiting surface 25a, which is used to contact the inner wall of the pot body to achieve radial limiting. In this embodiment, the limiting surface 25a is an inclined surface, forming an inverted trapezoidal structure.
