SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model aims at providing a can heat retaining carton, fully overcome the not enough of prior art.
The purpose of the utility model is realized by adopting the following technical scheme:
a carton that can keep warm which characterized in that: the carton comprises a carton body, wherein the carton body comprises a first waterproof film, a carton layer, a rock wool layer, a heat preservation layer and a second waterproof film which are sequentially arranged from outside to inside, heat preservation liquid is located inside the heat preservation layer, the heat preservation layer is designed with a temperature control device, and the temperature control device comprises an electric connection port, a main board, a refrigeration metal sheet and a heating resistance wire; be equipped with the crease on the carton body, through the crease folding formation heat preservation carton. The insulating liquid can be heated to 80 ℃ or cooled to-50 ℃.
The heat preservation layer is composed of a waterproof film, a heating resistance wire, a refrigeration metal sheet and an electric connection port, the waterproof film forms a sealing bag to serve as the outer layer of the heat preservation layer, heat preservation liquid is located in the sealing bag formed by the waterproof film, the electric connection port is arranged on the waterproof film, a control switch is arranged on the electric connection port, the electric connection port is connected with the mainboard, the mainboard is connected with the heating resistance wire and the refrigeration metal sheet, the heating resistance wire and the refrigeration metal sheet are arranged in the liquid and can heat and refrigerate the liquid, and when the heat preservation layer is used, the electric connection port on the film is plugged with electricity, so that heating or refrigeration can be carried out. Connect the electric mouth and can see through rock wool layer, the first waterproof membrane in carton layer and expose in the carton body outside, be equipped with sealed waterproof cover simultaneously.
Further, the heat preservation liquid is recyclable liquid with high specific heat capacity.
Further, the carton layer comprises a first carton layer and a third carton layer, and the first carton layer and the third carton layer are sequentially arranged between the first waterproof film and the rock wool layer from outside to inside; the first carton layer is waterproof kraft paper board or corrugated container board, the third carton layer is kraft paper board or corrugated container board, the corrugated container board is single corrugated container board, two corrugated container board, three corrugated container board or five corrugated container board.
Furthermore, the first waterproof film is a PE film, the thickness of the first waterproof film is 70-100 mu m, the second waterproof film is composed of a PE film and an aluminum foil heat-preservation film, and the aluminum foil is located on the innermost side of the box body. The aluminum foil has extremely low solar radiation absorption coefficient, and can isolate most heat transfer.
And further, tinfoil paper is arranged on one side of the rock wool layer close to the carton layer. Because the tin foil paper has better heat insulation effect, the heat insulation effect of the heat insulation carton can be further improved finally.
The utility model has the advantages that: the carton has waterproof function, and the design has the control by temperature change intermediate layer, can place the liquid that specific heat capacity is high in the intermediate layer to realize cold insulation or heat retaining purpose, practice thrift the space, the content is recoverable, and is friendly to the environment, and is not fragile.
