Description

Technical Field

[0001] The utility model relates to the technical field of cold chain logistics boxes, and in particular to a cold chain logistics box with cold and hot separation. Background Art

[0002] A cold chain logistics box is a packaging container specially used for transporting and storing refrigerated, frozen and other low-temperature foods and other perishable items. It uses some special materials and technologies to effectively protect the quality and safety of food or items.

[0003] Cold chain logistics boxes are widely used in industries such as food, medicine, cosmetics, and biological products, and are especially important in international trade. For example, fresh fruits, vegetables, meat, seafood, and medicines all need to maintain a certain temperature and humidity during transportation and storage. Therefore, cold chain logistics boxes have become the main choice for the transportation and storage of these items.

[0004] The prior art publication number is CN219030451U, which is a cold chain logistics box with hot and cold separations, including a box body, a box cover is installed on the upper end of the box body, a sealing strip is provided at the connection between the box body and the box cover, a control unit is installed on the upper end of the box cover, a battery is installed on one side of the control unit, a heat exhaust cavity is provided in the box cover, a semiconductor refrigeration sheet is installed in the middle of the bottom end of the heat exhaust cavity, and a refrigeration plate is installed at the lower end of the semiconductor refrigeration sheet.

[0005] The cold chain logistics box can cool the box body through semiconductor refrigeration sheets, which can ensure a low-temperature storage environment for the cold chain logistics box and improve the use function of the cold chain logistics box.

[0006] However, it only has one storage space. In order to ensure the refrigeration effect of the products, it can generally only store products of the same type or in the same refrigeration temperature zone. The main reason is that different products have different refrigeration temperature requirements. If two products with different refrigeration requirements are placed in the same storage space, the refrigeration effect of one of the products will be reduced. Therefore, improvements are proposed.
