However, one or more embodiments can also be implemented by those skilled in the art without these specific details.
[0039] Embodiment 1
[0040] As Figure 1 shown, an easily cleanable container lid includes a cover body 1, a fastener 2 fixed to the inner part of the cover body 1, a handle 3 fixed to the outer part of the cover body 1, an inner seal 4 and an outer seal 5.
[0041] The middle region of the cover body 1 is higher than the peripheral region, and its cross-section is circular. The part of the cover body 1 adjacent to the cavity of the cooking appliance when used in cooperation with the cooking appliance is defined as the inner side of the cover body 1. Correspondingly, the other side away from the cavity of the cooking appliance is the outer side of the cover body 1. The first through hole 6 is opened in the middle region of the cover body 1.
[0042] The fastener 2 is provided with a first connecting portion, and the handle 3 is provided with a second connecting portion. The second connecting portion is detachably and fixedly connected to the first connecting portion through the first through hole 6.
