Background technique

With the rapid development of the express delivery industry, when transporting express items that need to be refrigerated, the outside of the express items is usually wrapped with a layer of ice cubes, and then the outside of the ice cubes is wrapped with foam to keep them warm. The block will gradually melt over time, and the cold storage of the express items will fail, causing the express items to be damaged by heat, and the cold storage time is short. The design is suitable for the express industry, and a cooler with a longer cold storage time is necessary. .

The present invention designs a packing box to solve the above problems.

Contents of the invention

In order to solve the above-mentioned defects in the prior art, the present invention discloses a packing box, which is realized by adopting the following technical solutions.

A packing box is characterized in that it includes a top cover, an outer box body, a reaction module, a freezing shell, a storage box body, and a freezing block, wherein the storage box body is installed inside the outer box body and is located in the middle of the outer box body position; the storage box provides storage space for items that need to be refrigerated; the top cover is installed on the upper side of the outer box; the freezing shell is square, and the lower side of the freezing shell is respectively installed with a Freezing block, the freezing block is hollow, and the freezing block communicates with the freezing shell; the freezing block is made of soft material; the freezing shell is installed on the underside of the top cover, and the four freezing blocks are connected to the storage box and the outer box Spatial coordination; there is a freezing medium in the freezing shell and the four freezing blocks; during the use of the packaging box, the freezing shell needs to be frozen first, and the freezing medium in the four freezing blocks is flowed back into the freezing shell before freezing. Since the frozen block is a soft material, after the freezing medium in the frozen block is flowed back into the frozen shell, the four frozen blocks can be pressed into a ball, placed on the frozen shell, and then the frozen shell is placed in the refrigerator , carry out freezing treatment to the freezing shell, when the freezing shell designed by the present invention is subjected to freezing treatment, the freezing medium in the four freezing blocks is flowed back into the freezing shell, and then the four freezing blocks are pressed into a ball and placed in the freezing shell On, reduce the space that freezing shell takes up refrigerator when freezing, be convenient to freezing shell freezing; And in the present invention, freezing block is soft material, and its effect is to be convenient to after the freezing medium in freezing block flows back in freezing shell, freezing block is refrigerated. compression.

The reaction modules are installed in the cryo-enclosure.

The above-mentioned reaction module has two substances that undergo an endothermic reaction upon contact.

As a further improvement of this technology, a plurality of heat conduction fins are evenly installed around the reaction module, and the function of the heat conduction fins is to facilitate the reaction module to absorb the heat of the freezing medium in the freezing shell, so as to cool down the freezing medium as soon as possible.
