One end of the elastic piece 15 acting on the shell 12 abuts against the shell 12, so that elastic biasing action on the buckle 14 is realized.

Specifically, the limiting structure 122 may be a closed limiting ring or a plurality of limiting plates. In this embodiment, the limiting structure 122 includes a plurality of limiting plates, and one end of the elastic member 15 is clamped between the plurality of limiting plates.

The plurality of limiting plates include two first limiting plates 1221 arranged in parallel, and the first limiting plates 1221 are strip-shaped and have a length extending direction Y. In this embodiment, the two first limiting plates 1221 are parallel to each other and spaced apart from each other along the spacing direction X of the two supporting arms 121, and the extending direction Y of the two first limiting plates 1221 is perpendicular to the spacing direction X.

The first limiting plate 1221 may not be perpendicular to the direction X in the direction of the length extension, and the relationship with the supporting arm 121 in this embodiment is designed for convenience of processing.

In order to further limit the movement of the elastic element 15 in all directions, the plurality of limiting plates 122 further includes a second limiting plate 1222 and a third limiting plate 1223, the second limiting plate 1222 and the third limiting plate 1223 are spaced apart in the length extending direction Y of the first limiting plate 1221, the elastic element 15 is further clamped between the second limiting plate 1222 and the third limiting plate 1223 to achieve the limiting in the extending direction Y, and Y is perpendicular to X, so that the position of the elastic element 15 can be fixed in all directions.

The above elements are all connected with each other by assembling, so that the design for facilitating the assembly of the elastic element 15 is further provided in this embodiment, the second limit plate 1222 and the third limit plate 1223 are sequentially arranged along the assembly direction Z of the elastic element 15, wherein the height of the second limit plate 1222 protruding from the housing 12 is gradually increased along the assembly direction Z, i.e. gradually increased along the direction toward the limit area 123, and gradually increased from zero, so as to guide the elastic element 15 during the assembly process of the elastic element 15, i.e. when the elastic element 15 is assembled, the elastic element 15 can be guided into the assembly position along the inclined plane of the second limit plate 1222, and finally clamped between the plurality of limit plates.

Besides, in order to ensure that the assembly process of the elastic element 15 is smoother, the two first limiting plates 1221 have enough length in the extending direction Y, so that the second limiting plate 1222 and the third limiting plate 1223 are both located between the two first limiting plates 1221, and the two first limiting plates 1221 also play a role in guiding and limiting in the assembly process of the elastic element 15.

In the embodiment, the cross ribs 142 are arranged on the buckle plate 14, the limiting structure 122 is arranged on the shell 12, and the installation of the elastic element 15 is also facilitated, because the size of the buckle plate 14 is smaller than that of the shell 12, the buckle plate 14 is taken and the buckle plate 14 is installed on the shell 12 during assembly, and the size of the elastic element 15 is smaller, if the buckle plate 14 is installed on the shell 12, the positioning installation of the elastic element 15 on the buckle plate 14 is not easy to operate and realize when the buckle plate 14 is installed on the shell 12.

In addition, in the embodiment, the elastic member 15 is a spring having a diameter of 4mm to 8mm, specifically 4mm, 6mm, or 8 mm. The diameter of the elastic member 15 is selected in relation to the specific structure of the product, and a 6mm diameter elastic member is generally used in rice cookers.

The size of the cross rib 142 and the size of the limiting structure 122 are designed according to the size of the elastic element 15, for example, the diameter of the periphery of the cross rib 142 is slightly larger than the diameter of the elastic element 15, so that the elastic element 15 can be elastically sleeved on the cross rib 14.

The distance between the two first limiting plates 1221 is equal to or slightly greater than the elastic element 15, and the distance between the second limiting plate 1222 and the third limiting plate 1223 is equal to or slightly greater than the elastic element 15, which is a theoretical design, but in actual circumstances, a slight gap will be left between the limiting structures 122 and the elastic element 15, so that the elastic element 15 can be clamped between the limiting structures 122.

In addition, in order to ensure the effective restriction effect on the elastic element 15, the height of the limiting structure 122 protruding the housing 12 is 0.5mm to 3.0mm, further 1.5mm to 2mm, and specifically may be 0.5mm, 3.0mm, 1.5mm, or 2.0 mm. For example, the heights of the first limiting plate 1221 and the third limiting plate 1223 are fixed and are 1.5 mm; the height of the second stopper plate 1222 is gradually changed from 0 to 1.5 mm.

In this embodiment, the position deviation is not easily generated when the elastic member is compressed or stretched by arranging the limit plate on the housing. Furthermore, the limiting plate is correspondingly designed, so that the assembly of the elastic part in actual production is facilitated, and the service life of the related mechanical structure of the elastic part of the cooking appliance is also ensured.
