The bottom wall 310 and the side wall 311 enclose the second receiving cavity 331. The second end 3011 of the upper cover 30 is located in the second accommodating cavity 331 and attached to the sidewall 311, so as to effectively ensure the sealing performance of the cooling box and prevent water leakage. The shape of the bottom wall 310 is the same as the shape of the surface of the lid assembly 2, so as to effectively ensure the close fit between the bottom wall 310 and the lid assembly 2, and further effectively ensure the heat conduction effect of the bottom wall 310. The fixing portion 312 includes a first supporting portion 3120 arched upward from the side wall 311 and a covering portion 3122 extending from the first supporting portion 3120. The first abutting portion 3120 is tightly attached to the connecting portion 3021, so that the sealing performance of the cooling box is effectively ensured, and water leakage is prevented. The abutting part 3022 is positioned in the accommodating part 3123 surrounded by the covering part 3122, and the covering part 3122 is attached to the abutting part 3022, thereby effectively ensuring the sealing performance of the cooling box, preventing water leakage and enhancing the aesthetic property of the cooling box. In the illustrated embodiment, the covering portion 3122 is attached to the abutting portion 3022 but not attached to the connecting portion 3021, and in other embodiments, the covering portion 3122 may not be attached to the abutting portion 3022 but only attached to the connecting portion 3021 or attached to both the abutting portion 3022 and the connecting portion 3021, thereby achieving the purpose of sealing and waterproofing.

In the illustrated embodiment, the upper cover 30 is made of silicon rubber, and compared with the lower cover 31 made of metal, the thermal conductivity of the upper cover 30 is reduced, so that not only can the upper cover 30 be prevented from being overheated to cause scalding, but also the cost can be reduced. The upper cover 30 may also be made of other non-metallic materials, such as plastic.

The cooling box comprises an injection port 3012, cooling substances can be replaced, and the cooling speed of the pot cover component 2 can be increased through multiple replacement, so that the cooling box has a better cooling effect; the injection port 3012 is communicated with the outside, so that the heat of the cooling material can be conducted out, the temperature of the cooling material can be effectively reduced, and the cooling effect of the cooling box is further improved; the cooling box comprises an upper cover 30 and a lower cover 31 which are made of different materials, the thermal conductivity of the lower cover 31 is greater than that of the upper cover 30, scalding caused by overheating of the upper cover 30 can be prevented, and cost can be reduced; the upper cover 30 is made of a heat-insulating plastic flexible material, such as silicon rubber, so that scalding due to overheating of the upper cover 30 is prevented, meanwhile, the upper cover 30 can be deformed, and damage to the upper cover 30 after solidification of cooling substances, such as damage to the upper cover 30 due to freezing of water, can be prevented; the cooling box is assembled in the space 210 formed between the handle part 21 and the main body 20 of the pot cover assembly 2, the cooling box can be effectively fixed, no additional fixing structure is needed, and the operation is simple and convenient.
