Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, specifically a portable box-type refrigerator. Background Technology

[0002] Chinese Patent Application No. CN202411523098.9 discloses a lightweight refrigerator / bag that is easy to carry outdoors. It includes an inner liner with at least one freezing chamber; an insulation layer fitted over the outer surface of the inner liner; a bottom support assembly located at the bottom of the inner liner and having a receiving cavity within it; a cooling assembly located within the receiving cavity and cooling the freezing chamber of the inner liner; an outer skin layer fitted over the insulation layer and the bottom support assembly; a lid that covers the inner liner and insulation layer to seal the freezing chamber, with one side of the lid rotatably connected to the outer skin layer; and a carrying strap attached to the outer skin layer for the user to carry. The aforementioned refrigerator's inner liner, insulation layer, and bottom support assembly form a single unit when covered by the outer skin. However, the outer skin is merely a snap-fit ​​connection to the outside of the insulation layer and bottom support assembly, resulting in low assembly stability. This leads to the outer skin easily separating from the insulation layer and bottom support assembly during use. Furthermore, the lack of an outer cover on the lid not only results in poor sealing, causing cold air leakage from the freezer cavity and wasting resources, but also compromises the overall appearance and makes it prone to damage. Therefore, further improvements are necessary. Utility Model Content
