[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] The inner cover structure of various food refrigeration machines, such as Figures 1-2As shown, the system includes a refrigeration unit body 1 and a top cover 2 that is openable and closable on the refrigeration unit body 1. The refrigeration unit body 1 has an upward-opening receiving cavity 11, in which an inner liner 4 is separately provided. The inner liner 4 has an upward-opening refrigeration cavity 41. An inner cover 3 is detachably installed on the top cover 2. The inner cover 3 has an assembled state and a separated state relative to the top cover 2. When the inner cover 3 is in the assembled state and the top cover 2 is closed on the refrigeration unit body 1, the inner cover 3 is sealed to the opening of the refrigeration cavity 41. When the top cover 2 is open relative to the refrigeration unit body 1 and the inner cover 3 is in the separated state, the inner cover 3 is sealed to the inner liner 4.

[0035] like Figures 1-3 and Figure 6 As shown, the inner cover 3 is detachably installed on the side of the top cover 2 facing the inner liner 4 through a positioning structure, so that when the top cover 2 is closed on the main body 1 of the refrigeration unit, the inner cover 3 on the inward side can maintain an effective seal with the opening of the inner liner 4. The positioning structure includes a snap-fit ​​post 231 and a snap-fit ​​sleeve 31. The snap-fit ​​post 231 protrudes from the bottom of the top cover 2, and the snap-fit ​​sleeve 31 is fixed on the inner cover 3. The snap-fit ​​post 231 and the snap-fit ​​sleeve 31 engage with each other. The snap-fit ​​fixing method of the inner cover 3 improves the convenience of removing and installing the inner cover 3 from the top cover 2 and enhances the comfort of user operation. A handle 32 is provided in the middle of the inner cover 3. When the inner cover 3 is in the assembly state, the handle 32 is located on the side of the inner cover 3 facing the refrigeration cavity 41. The user can easily remove the inner cover 3 from the top cover 2 through the handle 32. After the inner cover 3 is separated from the top cover 2, it can be closed on the inner liner 4 simply by flipping it horizontally.

[0036] like Figures 1-4 and Figure 6 As shown, the handle 32 is arched, and a hand-holding groove 321 is formed between the handle 32 and the inner cover 3. The inner cover 3 has a mounting hole 33, one end of which connects to the hand-holding groove 321. One end of the snap-fit ​​sleeve 31 passes through the mounting hole 33 and extends into the hand-holding groove 321. The hand-holding groove 321 improves the user's hand comfort when gripping the handle 32. The snap-fit ​​sleeve 31 is made of elastic polymer material, such as rubber, silicone, or other elastic plastics. An annular groove 311 is formed on the outer wall of the snap-fit ​​sleeve 31 along the circumference. The snap-fit ​​sleeve 31 connects to the mounting hole 33 through the annular groove 311. The snap-fit ​​design allows the snap-fit ​​sleeve 31 to be detachably installed on the inner cover 3, facilitating the assembly and subsequent replacement of the snap-fit ​​sleeve 31. At the same time, the snap-fit ​​sleeve 31, made of elastic polymer material, helps to increase the friction between the snap-fit ​​sleeve 31 and the snap-fit ​​post 231, thereby improving the stability of the inner cover 3 on the top cover 2. The bottom of the top cover 2 is recessed inward to form a cavity 232, and the snap-fit ​​post 231 protrudes from the bottom of the cavity 232, so that the snap-fit ​​post 231 is hidden inside the cavity 232, reducing the space occupied by the snap-fit ​​post 231 in the refrigeration cavity 41 and increasing the refrigeration volume of the inner liner 4.

[0037] like Figures 1-6 As shown, the top cover 2 includes an upper cover body 21, a lower cover body 23, and an insulation layer 22 filled between the upper cover body 21 and the lower cover body 23. The sandwich design of the top cover 2 can improve the cold preservation performance of this food refrigeration unit. The inner cover 3 has annular positioning parts 34 vertically arranged on both the upper and lower sides of its edge. The top cover 2 has annular grooves 24 corresponding to the annular positioning parts 34. The inner cover 3 is engaged with the annular groove 24 on one side through the annular positioning part 34, and the inner cover 3 is inserted and sealed to the opening of the refrigeration chamber 41 through the annular positioning part 34 on the other side. The annular positioning part on the upper side of the inner cover 3 is used to seal the connection. The interlocking action between part 34 and inner cover 3 improves the anti-shaking performance of inner cover 3 when installed at the bottom of top cover 2. At the same time, the annular positioning part 34 on the lower side of inner cover 3 and the inner cavity of inner liner 4 are interlocked to achieve a seal, which helps to improve the sealing ability between inner cover 3 and inner liner 4. The outer wall of the annular positioning part 34 is provided with a guide slope 341. The annular positioning parts 34 on both sides are guided and interlocked with the corresponding refrigeration cavity 41 and annular groove 24 through the guide slope 341. The addition of guide slope 341 improves the convenience of interlocking annular positioning part 34 with inner liner 4 and annular groove 24.

[0038] The basic working principle of this utility model is as follows: A top cover 2 is set on the main body 1 of the refrigeration unit, and an inner cover 3 is detachably installed at the bottom of the top cover 2. When the top cover 2 is sealed and closed at the opening of the receiving cavity 11 of the main body 1 of the refrigeration unit, the inner cover 3 located at the bottom of the top cover 2 is sealed and closed with the opening of the refrigeration cavity 41 of the inner liner 4. The top cover 2 and the inner cover 3 achieve double sealing, which improves the odor prevention performance and the cold preservation effect. When using it, whether food is directly refrigerated in the inner liner 4 or garbage bags are placed in the inner liner 4, when cleaning the items in the inner liner 4, simply open the top cover 2, then remove the inner cover 3 from the top cover 2 and close the inner cover 3 on the inner liner 4 to isolate the odor of the items in the inner liner 4. Afterwards, the user can carry the inner liner 4 with the inner cover 3 closed by hand to clean the food or garbage. It has the effect of improving the cold preservation performance and effectively preventing the odor from coming out during the transportation of food or garbage.
