However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0032] The first embodiment, as Figure 1 , 2As shown in Figure 6, the portable cold storage bag can be used for refrigerating breast milk. Of course, it can also be used for refrigerating other objects besides breast milk, such as medicines, beverages, fruits, etc., including a refrigeration module 1 and a bag body 2 with a storage cavity 21. The utility model has the advantages of being convenient to carry and use. The refrigeration module 1 can be detachably arranged on the bag body 2 and used to cool the storage cavity 21, which is convenient for cleaning and maintaining the refrigeration module 1 and the bag body 2 separately. Of course, if one of the refrigeration module 1 and the bag body 2 is damaged, it can also be cleaned and maintained. For targeted replacement, the package body 2 can also be designed into different styles to match the same refrigeration module 1.

The refrigeration module 1 includes a main body 11, a refrigerator 12 arranged on the main body 11, and a heat exchange part 13 connected to the refrigerator 12 for heat exchange. When the refrigeration module 1 is arranged on the package body 2, the heat exchange part 13 exchanges heat with the storage cavity 21, that is, when the refrigeration module 1 is running, the refrigerator 12 freezes and cools the storage cavity 21 through the heat exchange part 13.

[0033] In some embodiments of the present invention, Figure 2 As shown, the refrigerator 12 is a semiconductor refrigeration component.
