[0041] Reference Figures 1 to 3 The mobile cold air box of the utility model is implemented as follows:

[0042] The mobile cold air box includes a refrigeration device 100, a placement table 200, and a container.

[0043] The refrigeration device 100 is a conventional refrigeration device. The refrigeration device 100 includes an evaporator 130, a compressor 150, a condenser 160, and a throttling device which are connected end to end in sequence. The function of the compressor 150 is to compress the refrigerant vapor with a lower pressure into the refrigerant vapor with a higher pressure, so that the volume of the refrigerant vapor is reduced and the pressure is increased; the compressor 150 inhales the refrigerant vapor with a lower pressure coming out of the evaporator 130, increases the pressure and then sends it to the condenser 160, condenses it into a refrigerant liquid with a higher pressure in the condenser 160, and after throttling by the throttling device, becomes a refrigerant liquid with a lower pressure, and then is sent to the evaporator 130, absorbs heat and evaporates in the evaporator 130 to become a refrigerant vapor with a lower pressure, and then is sent to the compressor 150, thereby completing the refrigeration cycle.

[0044] To this end, the refrigeration device 100 is provided with an air outlet 110 for blowing out cold air and an air inlet 120 for sucking in air.

[0045] The placement table 200 is installed outside the refrigeration device 100 , and the air outlet 110 and the air inlet 120 are directly opposite to the top of the placement table 200 .

[0046] The container (not shown in the figure) is an insulation box. The side wall of the container is provided with an inlet and an outlet. The inlet and the outlet are respectively provided with openable and closable closing components. The closing components can be devices such as nut covers, cover plates, and plugs. After the closing components close the inlet and the outlet, the container forms an insulation space to block external heat.

[0047] After the closing component is opened, the inlet is connected to the air outlet 110 of the refrigeration device 100, and the outlet is connected to the air inlet 120 of the refrigeration device 100, so that a circulating airflow is formed between the refrigeration device 100 and the container, so that the cold air inside the refrigeration device 100 can be blown into the container, and the hot air in the container can enter the refrigeration device 100 for cooling.

[0048] There are many ways to detachably connect the air outlet 110 and the inlet. The detachable connection method between the air inlet 120 and the outlet can refer to the air outlet 110 and the inlet. For example, a rotatable threaded sleeve is provided at the inlet, and a solenoid is provided at the air outlet 110, and the threaded sleeve and the solenoid cooperate to achieve communication. Alternatively, a plug is provided at the inlet, and a jack is provided at the air outlet 110, and the plug cooperates with the jack to achieve communication. Alternatively, a hose is provided at the air outlet 110, and the hose is extended into the inlet, and the hose is squeezed with the inner side wall of the inlet to achieve sealing, so that the hose is connected to the inside of the container.

[0049] Place the container on the placement table 200, open the inlet and the outlet, and use the refrigeration device 100 to blow cold air into the container through the air outlet 110 and the inlet after refrigeration, so that the hot air in the container flows back to the refrigeration device 100 through the outlet and the air inlet 120 for cooling, so that the temperature inside the container is quickly reduced to achieve a low-temperature environment, and then place the items in the container for storage, for example, reduce the temperature inside the container to below -20°C, and then place the frozen items in the container for storage.

[0050] When the items need to be transported, the container is taken out from the placement table 200, the inlet and the outlet are closed, and then the items are transported to prevent the internal temperature of the container itself from causing the temperature of the items to rise.

[0051] In this embodiment, a quick connector assembly is provided to connect the inlet and the air outlet 110 , and a quick connector assembly is provided to connect the outlet and the air inlet 120 .

[0052] The quick connector assembly is more convenient to fit and has better sealing performance, so that the container can be easily disassembled or assembled from the placement table, thereby improving the convenience of taking and placing the container.

[0053] In some embodiments, the quick connector assembly includes a plug 310, a socket, a cover plate, and an elastic member. For example, the plug 310 is set at the air outlet 110 or the air inlet 120 of the refrigeration device 100, and the socket is set at the inlet or outlet of the container.

[0054] The cannula 310 extends outward, the cannula is provided with a port, the socket is provided with a socket, and the socket is connected to the interior of the container.

[0055] The cover plate is arranged in the insertion hole and can slide along the insertion hole. The elastic member is installed inside the insertion hole and abuts against the cover plate. The elastic force of the elastic member makes the cover plate have a tendency to close the insertion hole.

[0056] After placing the container on the placement table 200, align the air outlet 110 with the inlet and the air inlet 120 with the outlet, then push the container to insert the plug 310 into the socket of the socket, and make the end of the plug 310 push the cover plate so that the cover plate can push the elastic part and open the socket, so that the plug 310 is connected with the inside of the container.

[0057] In some embodiments, the quick connector assembly is further provided with a wind shield 320 , which is installed at the end of the cannula 310 , and the wind shield 320 blocks the port of the cannula 310 .

[0058] The wind shield 320 blocks the port of the insert tube 310, so that the airflow flowing into or out of the port of the insert tube 310 is changed by the wind shield 320, so as to form multiple airflows inside the container, ensuring that the cold air flows through every corner inside the container, so that the temperature of the container is reduced more evenly.

[0059] In some embodiments, the refrigeration device 100 is provided with a refrigeration chamber 101 and a heat exchange chamber 102 . The refrigeration chamber 101 and the heat exchange chamber 102 are separated from each other, and a through air outlet 110 and an air inlet 120 are provided on a side wall of the refrigeration chamber 101 .

[0060] The refrigeration device 100 is further provided with an evaporator 130 and a refrigeration fan 140 .

[0061] The refrigeration device 100 is further provided with a compressor 150, a condenser 160, and a throttling device.

[0062] The evaporator 130 and the refrigeration fan 140 are arranged in the refrigeration chamber 101 , and the compressor 150 , the condenser 160 , and the throttling device are arranged in the heat exchange chamber 102 .

[0063] The evaporator 130 and the refrigeration fan 140 for refrigeration are arranged in the refrigeration chamber 101, and the compressor 150, the condenser 160 and the throttling device for switching the form of the heat medium are arranged in the heat exchange chamber 102 to prevent the heat generated by the compressor 150, the condenser 160 and the throttling device during operation from being conducted to the evaporator 130 or the refrigeration fan 140, resulting in a reduction in the refrigeration capacity.

[0064] In some embodiments, the refrigeration chamber 101 is arranged above the heat exchange chamber 102, and the refrigeration device 100 is also provided with a water receiving pan 400, which is installed inside the heat exchange chamber 102. A first drain pipe 170 is arranged at the bottom of the refrigeration chamber 101, and the top end of the first drain pipe 170 is connected to the refrigeration chamber 101, and the bottom end of the first drain pipe 170 is connected to the water receiving pan 400.

[0065] The condensed water generated when the evaporator 130 or the refrigeration fan 140 in the refrigeration chamber 101 generates refrigeration will drip to the bottom of the refrigeration chamber 101, and the condensed water accumulated at the bottom of the refrigeration chamber 101 will be discharged to the water receiving tray 400 of the heat exchange chamber 102 through the first drain pipe 170. The condensed water can properly absorb the heat in the heat exchange chamber 102, which helps to reduce the operating temperature of each component in the heat exchange chamber 102. The condensed water is heated and evaporated, and the user does not need to discharge the condensed water regularly, so the condensed water can be reused.

[0066] In some embodiments, the placement table 200 is provided with a water receiving trough 210, which is located at the bottom of the placement table 200, and a second drain pipe 180 is provided at the bottom of the water receiving trough 210. The top end of the second drain pipe 180 is connected to the water receiving trough 210, and the bottom end of the second drain pipe 180 is connected to the water receiving tray 400.

[0067] As the temperature of the container decreases, condensed water is likely to form on the outer wall of the container. The condensed water on the outer wall of the container is recovered into the second drain pipe 180 by the water receiving trough 210. The second drain pipe 180 drains the water into the water receiving tray 400 to reuse the condensed water.

[0068] In some embodiments, the refrigeration chamber 101 is disposed beside the placement table 200 , and the water receiving tank 210 is located below the air inlet 120 and the air outlet 110 .

[0069] Since the placement table is used to place containers, during the cooling process of the containers, due to the small gap between the air outlet 110 and the inlet, and the small gap between the air inlet 120 and the outlet, the side walls of the container facing the air outlet 110 and the air inlet 120 are cooled down due to the cold air leaking from the gaps, which easily causes condensed water to accumulate on the side walls and then drip down into the water receiving trough 210. The condensed water in the water receiving trough 210 then drips along the second drain pipe 180 to the water receiving tray 400, so that the condensed water is reused for a second time.

[0070] In some embodiments, the compressor 150 is provided with a heat exchange pipe connected to the condenser 160 , and a portion of the heat exchange pipe extends into the water receiving pan 400 .

[0071] The condensed water in the water receiving pan 400 is used to pre-cool the refrigerant flowing from the compressor 150 to the condenser 160 , so as to improve the heat release effect of the condenser 160 on the refrigerant.

[0072] In some embodiments, a thermal insulation layer is disposed around the refrigeration chamber 101 .

[0073] The refrigeration chamber 101 is isolated from the outside by the heat-insulating layer, so that the interior of the refrigeration chamber 101 is maintained at a relatively low temperature.

[0074] In some embodiments, a one-way valve 171 is provided in the first drain pipe 170 .

[0075] The conducting direction of the one-way valve 171 is from the first drain pipe 170 to the water receiving pan 400 , so the condensed water can flow along the first drain pipe 170 through the one-way valve 171 to the water receiving pan 400 , and the one-way valve 171 is used to prevent the hot air in the heat exchange chamber 102 from flowing into the refrigeration chamber 101 .

[0076] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
