A plurality of storage boxes 200 are provided, and the plurality of storage boxes 200 are provided in a one-to-one correspondence with the plurality of accommodating cavities 102 .

[0053] In this embodiment, a plurality of accommodating cavities 102 are provided, that is, the box body 101 defines a plurality of accommodating cavities 102 for placing a plurality of storage boxes 200. The plurality of storage boxes 200 are arranged in a one-to-one correspondence with the plurality of accommodating cavities 102, so that the plurality of storage boxes 200 can be respectively arranged in the corresponding accommodating cavities 102, and then the plurality of storage boxes 200 can be installed in the box body 101.

[0054] Optionally, the accommodating cavity 102 of the box body 101 has a take-out port, and the storage box 200 can be pushed into the accommodating cavity 102 from the take-out port to install the storage box 200 in the box body 101.

[0055] Combination Figure 1 and Figure 4 As shown, optionally, when a plurality of accommodating cavities 102 are provided, each accommodating cavity 102 is correspondingly provided with an air supply duct 103 and an air return duct 104 to achieve plug-in matching of the corresponding storage box 200 , thereby achieving refrigeration of each storage box 200 .

[0056] Understandable, combined Figure 1 , Figure 4 and Figure 5As shown, the volume size of the storage box 200 is not limited. Moreover, the volume sizes of the plurality of storage boxes 200 may be the same or different. It is sufficient that each storage box 200 corresponds to the size of the receiving cavity 102 corresponding to the storage box 200, that is, each storage box 200 can be installed in the corresponding receiving cavity 102.

[0057] Combination Figures 1 to 3 As shown, in some embodiments, the storage box 200 further includes a heat preservation shell 203 and a door body 204. The heat preservation shell 203 defines a storage space with an opening. The heat preservation shell 203 is provided with an air inlet 201 and an air outlet 202. The door body 204 is rotatably disposed on the heat preservation shell 203, and the door body 204 is located at the opening.

[0058] In this embodiment, the heat-insulating shell 203 defines a storage space with an opening, providing a space for users to store items and enabling users to take and put items from the opening.

[0059] In this embodiment, the heat preservation shell 203 is provided with an air inlet 201 and an air outlet 202 for connecting the storage box 200 to the air supply duct 103 and the air return duct 104 respectively, so that when the storage box 200 is installed in the box body 101, the items in the storage box 200 can be cooled.

[0060] In this embodiment, the door body 204 is rotatably disposed on the heat-insulating shell 203 , and the door body 204 is located at the opening, so that the door body 204 can rotate relative to the heat-insulating shell 203 to open or close the storage box 200 .

[0061] Optionally, the air inlet 201 and the air outlet 202 are both arranged opposite to the opening of the storage space, which is convenient for taking and placing items, and also facilitates the installation of the storage box 200 on the box body 101, thereby improving the user experience.

[0062] It is understandable that the manner in which the door body 204 is rotatably arranged on the heat-insulating shell 203 is not limited and can be designed as required. For example, the door body 204 is connected to the heat-insulating shell 203 via a hinge to realize that the door body 204 is rotatably arranged on the heat-insulating shell 203.

[0063] In some embodiments, the storage box 200 is made of thermal insulation material.

[0064] In this embodiment, the storage box 200 is made of heat-insulating material, which can improve the heat-insulating performance of the storage box 200 .

[0065] For example, when the storage box 200 is removed from the box body 101, the thermal insulation material can keep the storage box 200 in a heat preservation state, which makes it convenient for the user to move the storage box 200 and the items in the storage box 200 as a whole, while keeping the items in the storage box 200 in a heat preservation state to meet the use requirements. When the storage box 200 is installed in the box body 101, when the temperature in the storage box 200 reaches the cooling target temperature, the air supply duct 103 can also stop supplying cold air to the storage box 200. The thermal insulation material can keep the storage box 200 in a heat preservation state until the temperature in the storage box 200 reaches the temperature required for cooling, and the cold air circulation inside the refrigeration device 100 is started again.

[0066] Optionally, the box body 101 is made of thermal insulation material to improve the thermal insulation performance of the refrigeration device 100 .

[0067] It is understandable that the thermal insulation material is not limited. For example, the thermal insulation material is polyurethane foam.

[0068] Combination Figures 1 to 4 As shown, in some embodiments, the storage box 200 further includes an air inlet door 205. The air inlet door 205 is rotatably disposed on the inner wall of the heat-insulating shell 203, and the position of the air inlet door 205 corresponds to the position of the air inlet 201. The air inlet door 205 can rotate relative to the heat-insulating shell 203 to open or block the air inlet 201.

[0069] In this embodiment, the air inlet damper 205 is rotatably arranged on the inner wall of the heat preservation shell 203, and the position of the air inlet damper 205 corresponds to the air inlet 201, so that the air inlet damper 205 can be rotated relative to the inner wall of the heat preservation shell 203 to open or block the air inlet 201. In this way, when the storage box 200 is installed on the box body 101, the air inlet damper 205 opens the air inlet 201 and the air supply duct 103 is plugged with the air inlet 201 of the storage box 200. When the storage box 200 is disassembled from the box body 101, the air inlet damper 205 blocks the air inlet 201, so as to realize the heat preservation function after the storage box 200 is disassembled from the box body 101.

[0070] Optionally, the air inlet damper 205 includes a damper body and a motor. The motor is mounted on the inner wall of the heat-insulating shell 203. The driving end of the motor is connected to the damper body.

[0071] In this embodiment, the damper body can be driven by a motor to rotate relative to the inner wall of the heat-insulating shell 203 to open or block the air inlet 201 .

[0072] It can be understood that the air inlet damper 205 is not limited to the above structure. As long as the air inlet damper 205 can be rotated relative to the inner wall of the insulation shell 203. For example, the inner wall of the insulation shell 203 is provided with a rotating shaft. The air inlet damper 205 is rotatably arranged on the rotating shaft. A spring is mounted on the outer surface of the rotating shaft. One end of the spring is connected to the air inlet damper 205. The other end of the spring is connected to the rotating shaft. In the process of installing the storage box 200 on the box body 101, the air supply duct 103 pushes the air inlet damper 205 to rotate relative to the rotating shaft to open the air inlet 201 and compress the spring until the air supply duct 103 is plugged into the air inlet 201. In the process of disassembling the storage box 200 from the box body 101, the air supply duct 103 is moved out from the air inlet 201, and the spring reset drives the air inlet damper 205 to rotate relative to the rotating shaft to block the air inlet 201, thereby realizing the insulation function after the storage box 200 is disassembled from the box body 101.

[0073] Optionally, the air inlet damper 205 is provided with a sealing structure corresponding to the air inlet 201, so that when the air inlet damper 205 blocks the air inlet 201, the air inlet 201 is sealed to improve the heat preservation effect.

[0074] It is understandable that the sealing structure is not limited, and it only needs to be able to achieve sealing between the air inlet damper 205 and the air inlet 201. For example, the sealing structure uses a sealing rubber ring.

[0075] Combination Figures 1 to 4 As shown, in some embodiments, the storage box 200 further includes an air outlet door 206. The air outlet door 206 is rotatably disposed on the inner wall of the heat preservation shell 203, and the air outlet door 206 corresponds to the position of the air outlet 202. The air outlet door 206 can rotate relative to the heat preservation shell 203 to open or block the air outlet 202.

[0076] In this embodiment, the air outlet door 206 is rotatably disposed on the inner wall of the heat preservation shell 203, and the position of the air outlet door 206 corresponds to the position of the air outlet 202, so that the air outlet door 206 can be rotated relative to the inner wall of the heat preservation shell 203 to open or block the air outlet 202. In this way, when the storage box 200 is installed on the box body 101, the air outlet door 206 opens the air outlet 202 and the return air duct 104 is plugged with the air outlet 202 of the storage box 200. When the storage box 200 is disassembled from the box body 101, the air outlet door 206 blocks the air outlet 202, so as to achieve the heat preservation function after the storage box 200 is disassembled from the box body 101.

[0077] Optionally, the air outlet damper 206 includes a damper body and a motor. The motor is mounted on the inner wall of the heat-insulating shell 203. The driving end of the motor is connected to the damper body.

[0078] In this embodiment, the damper body can be driven by a motor to rotate relative to the inner wall of the heat-insulating shell 203 to open or block the air outlet 202 .

[0079] It can be understood that the air outlet door 206 is not limited to the above structure. As long as the air outlet door 206 can be rotated relative to the inner wall of the insulation shell 203. For example, the inner wall of the insulation shell 203 is provided with a rotating shaft. The air outlet door 206 is rotatably arranged on the rotating shaft. A spring is mounted outside the rotating shaft. One end of the spring is connected to the air outlet door 206. The other end of the spring is connected to the rotating shaft. In the process of installing the storage box 200 on the box body 101, the return air duct 104 pushes the air outlet door 206 to rotate relative to the rotating shaft to open the air outlet 202 and compress the spring until the return air duct 104 is plugged into the air outlet 202. In the process of disassembling the storage box 200 from the box body 101, the return air duct 104 is moved out from the air outlet 202, and the spring reset drives the air outlet door 206 to rotate relative to the rotating shaft to block the air outlet 202, thereby realizing the insulation function after the storage box 200 is disassembled from the box body 101.

[0080] Optionally, the air outlet door 206 is provided with a sealing structure corresponding to the air outlet 202, so that when the air outlet door 206 blocks the air outlet 202, the air outlet 202 is sealed to improve the heat preservation effect.

[0081] It is understandable that the sealing structure is not limited, and it only needs to be able to achieve sealing between the air outlet door 206 and the air outlet 202. For example, the sealing structure uses a sealing rubber ring.

[0082] Combination Figure 4 As shown, in some embodiments, the air supply end of the air supply duct 103 extends into the accommodating cavity 102 , and the air return end of the air return duct 104 extends into the accommodating cavity 102 .
