In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not 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 7, in a first embodiment, the cover assembly includes: an outer cover 10, an inner cover 20, and a positioning structure. The inner cap 20 is mounted inside the outer cap 10; and the positioning structure is arranged between the outer cover 10 and the inner cover 20, and the outer cover 10 and the inner cover 20 are in plug fit through the positioning structure.

By applying the technical scheme of the embodiment, the inner cover 20 is installed inside the outer cover 10, a positioning structure is arranged between the outer cover 10 and the inner cover 20, and the outer cover 10 and the inner cover 20 are in plug-in fit through the positioning structure. The above-mentioned positioning structure enables the inner cap 20 and the outer cap 10 to be positioned quickly, which improves the assembly efficiency, and meanwhile, because the inner cap 20 and the outer cap 10 are connected through the insertion structure, the positioning structure can also increase the fixing effect of the inner cap 20 and the outer cap 10. Therefore, the technical scheme of the embodiment effectively solves the problem of low assembly efficiency of the pot cover in the related art.

In the embodiment not shown in the figure, the inner cover and the outer cover can be connected in a clamping fit manner, the connection mode of the clamping structure is simple and convenient to set, and the assembly efficiency of the product can be improved.
