Unless specifically stated otherwise, the relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as exemplary only and not as limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

As shown in fig. 1 to 3, the cover assembly of the present embodiment includes: a buckle cover 10, a temperature collecting piece 30 of the exhaust pipe 20 and a safety valve 40. Wherein, be provided with heavy platform portion 12 on the roof 11 of buckle closure 10, heavy platform portion 12 includes rectangular shape bottom wall plane portion 121, satisfies between the length L1 of bottom wall plane portion 121 and the width L2 of bottom wall plane portion 121: L2/L1 is more than or equal to 40% and less than or equal to 55%; the exhaust pipe 20, the temperature sensor 30, and the safety valve 40 are all disposed through the bottom wall plane portion 121.

By applying the technical solution of the present embodiment, the top wall 11 of the buckle cover 10 is provided with the platform portion 12, and the platform portion 12 includes the elongated bottom wall plane portion 121, so that the exhaust pipe 20, the temperature collecting member 30 and the safety valve 40 can be better installed, and the sealing performance thereof can be ensured. Providing the counter sink portion 12 on the buckle closure 10 may reduce the strength of the buckle closure 10 due to the weak pressure-bearing capability of the planar structure. The bottom wall plane part 121 is formed in a long strip shape, and the ratio between the width L2 of the bottom wall plane part 121 and the length L1 of the bottom wall plane part 121 is 40% to 55%, and the pressure bearing capacity of the bottom wall plane part 121 is higher than that of a square or circular bottom wall plane part. The arrangement can reduce the influence of the arrangement of the counter sink part 12 on the strength of the buckle cover 10, so that the buckle cover 10 has strong pressure bearing capacity as a whole. Therefore, the technical scheme of the embodiment can effectively solve the problem that the strength of the buckle cover is reduced because the bottom wall of the sinking platform part in the related art is a plane.

When L2/L1 is greater than 55%, the shape of the bottom wall flat part 121 tends to be square, which makes the strength of the platform part 12 low, and thus makes the pressure-bearing capacity of the entire buckle cover 10 weak. When L2/L1 is smaller than 40, the bottom wall flat portion 121 is too narrow to facilitate the installation of the exhaust pipe 20, the temperature control member 30, and the safety valve 40, which may reduce the processing efficiency of the lid assembly. Preferably, L2/L1 may be 40%, 47% or 55%.

As shown in fig. 4, the top wall 11 of the buckle cover 10 is a convex structure with a high center and a low edge. The arrangement enables the buckle cover 10 to have high strength and high bearing capacity.

As shown in fig. 1 and 3, in the present embodiment, the center of the exhaust pipe 20, the center of the temperature collection member 30, and the center of the safety valve 40 are located on the same straight line. This arrangement makes it possible to make the width of the bottom wall flat portion 121 narrower to enhance the strength of the counter sink portion 12, thereby enhancing the pressure bearing capability of the entire buckle cover 10.

As shown in fig. 1 and 3, a straight line in which the center of the exhaust pipe 20, the center of the temperature acquiring member 30, and the center of the safety valve 40 are located coincides with a longitudinal center line L3 of the bottom wall planar portion 121. That is, the center of the exhaust pipe 20, the center of the temperature collecting member 30 and the center of the safety valve 40 are located at the middle position in the width direction of the bottom wall plane portion 121, so that the buckle cover 10 has a symmetrical structure, and the layout is more reasonable.

As shown in fig. 1 to 3, in the present embodiment, the ratio of the area of the projection of the bottom wall plane portion 121 on the horizontal plane to the area of the projection of the buckle cover 10 on the horizontal plane is in the range of 8% to 16%. The larger the ratio of the area of the projection of the bottom wall plane part 121 on the horizontal plane to the area of the projection of the buckle cover 10 on the horizontal plane is, the larger the area occupied by the bottom wall plane part 121 is, and the smaller the overall strength of the buckle cover 10 is. Setting this ratio in the range of 8% to 16% can reduce the influence of the setting of the counter sink portion 12 on the strength of the buckle cover 10, while ensuring that the bottom wall planar portion 121 has a sufficient area for mounting the exhaust pipe 20, the temperature collecting member 30, and the safety valve 40. When the ratio is less than 8%, the area for installing the exhaust pipe 20, the temperature collecting member 30, and the safety valve 40 is small, which is not favorable for installing the exhaust pipe 20, the temperature collecting member 30, and the safety valve 40, and may reduce the processing efficiency of the cover assembly. When the ratio is larger than 16%, the area occupied by the bottom wall plane portion 121 is large, and the entire pressure-bearing capacity of the buckle cover 10 becomes weak. Preferably, the above ratio may be 8%, 12% or 16%.

As shown in fig. 2 and 3, in the present embodiment, the counter sink portion 12 further includes a bottom-wall inclined surface portion 122 provided outside the bottom-wall planar portion 121. Since the bottom wall plane portion 121 is a plane structure, a folded angle structure is formed by directly connecting with the top wall 11 of the buckle cover 10, which is not beneficial to processing the buckle cover 10. The bottom wall inclined plane part 122 is arranged outside the bottom wall plane part 121, so that the bottom wall plane part 121 and the top wall 11 of the buckle cover 10 are in smooth transition, and the buckle cover 10 is easy to process.

Note that the above-mentioned "inner" refers to a side close to the center of the buckle cover 10, and correspondingly, "outer" refers to a side away from the center of the buckle cover 10. The outer side of the bottom wall plane portion 121 refers to the left side of the bottom wall plane portion 121 in fig. 3.

As shown in fig. 2 and 3, in the present embodiment, the platform portion 12 includes a first side wall plane portion 123 and a second side wall plane portion 124 which are parallel to each other, and a side wall arc surface portion 125 provided between the first side wall plane portion 123 and the second side wall plane portion 124, and the side wall arc surface portion 125 is provided at one end of the bottom wall plane portion 121 near the center of the buckle cover 10. The connection between the top wall 11 and the bottom wall plane 121 of the buckle cover 10 is realized by the first side wall plane 123, the second side wall plane 124 and the side wall arc 125, which has the advantages of simple structure and easy processing. It should be noted that the bottom wall plane portion 121 is an elongated structure having two ends, one of the two ends is closer to the center of the buckle cover 10 than the other end. The "end of the bottom wall plane portion 121 near the center of the buckle cover 10" mentioned above refers to the end on the left side in fig. 3.

As shown in fig. 4, a step structure 14 is provided on the sidewall 13 of the buckle cover 10. The step structure 14 can further ensure the strength of the buckle cover 10, so that the buckle cover 10 has strong bearing capacity.

As shown in fig. 2, the sidewall 13 of the buckle cover 10 is provided at a lower end thereof with a cover tooth 15. The cover teeth 15 can be buckled with the cover teeth on the pot body or the heat-insulating cover to realize pressure cooking.

Specifically, the buckle cover 10 is made of a stainless steel material. The stainless steel material can satisfy the strength requirement and the economic requirement of the buckle cover 10 at the same time.
