Description

Technical Field

[0001] The utility model relates to the technical field of takeout boxes, in particular to a perovskite battery takeout box capable of generating power independently. Background Art

[0002] Perovskite solar cells have the potential to become the most promising solar cell technology due to their high photoelectric conversion efficiency, low cost, and simple manufacturing. In just a few years, the conversion efficiency of perovskite cells has increased from an initial 3.9% to the current 23.3%. A takeout box is a container used to store and transport takeout food.

[0003] In the existing technology, the structure and function of the takeaway box are single and can only protect and transport the takeaway. There is no insulation component to keep the takeaway warm. In addition, merchants will install display screens on the outside of the takeaway box for advertising. However, the display screens are generally fixed with bolts, which makes it inconvenient to disassemble or maintain them and inconvenient to use.

[0004] Therefore, there is an urgent need to provide a perovskite battery takeout box that can generate electricity independently to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art takeout boxes, which have a single structure and function and can only protect and transport takeouts, but no insulation components are provided to keep the takeouts warm. In addition, merchants will advertise by installing display screens on the outside of the takeout boxes, but the display screens are generally fixed with bolts, which makes it inconvenient to disassemble or maintain them and inconvenient to use. A perovskite battery takeout box that can generate electricity independently is provided.

[0006] To solve the above technical problems, the present invention adopts a technical solution: providing a self-powered perovskite battery takeout box, comprising a display screen on the side of the takeout box body, a perovskite battery mounted on the outer surface of the box lid, a heat preservation assembly disposed at the bottom of the takeout box body, and a mounting assembly disposed between the display screen and the takeout box body;

[0007] The insulation assembly includes a partition disposed at the bottom of the inner wall of the takeout box body, a battery disposed at the bottom of the partition, and a heating wire disposed on the side of the battery. The top edge of the partition is provided with a protrusion, and the top of the protrusion is provided with an air guide hole connected to the space at the bottom of the partition.

[0008] The installation assembly includes a placement groove arranged on the outer surface of the takeaway box body, a fixing block installed on the back of the display screen, a limiting unit arranged at the end of the fixing block, and a limiting hole arranged on the side wall of the takeaway box body.

[0009] The utility model is further configured as follows: the edges of the takeaway box body cover are all provided with magic mother tapes, and the tops of the sides of the takeaway box body are all provided with magic son tapes.

[0010] The utility model is further configured as follows: a heat-insulating shell is provided on the outside of the battery, and a heat-insulating grid is installed on the bottom of the battery.

[0011] The present invention is further configured as follows: a first wire is provided between the perovskite cell and the storage battery, a second wire is provided between the storage battery and the heating wire, and a third wire is provided between the perovskite cell and the display screen.

[0012] The present invention is further configured as follows: there are two groups of the limiting units, and the two groups of the limiting units are relatively arranged at the ends of the fixing block.

[0013] The utility model is further configured as follows: the limiting unit includes a receiving groove arranged at the end of the fixed block, one end of an extrusion piece fixedly connected to the side wall of the receiving groove, and one end of a limiting rod fixedly connected to the other end of the extrusion piece, and the other end of the limiting rod is adapted to the size of the limiting hole.

[0014] The utility model is further configured as follows: a slot is provided on the top of the takeaway box body, and a plug board is provided inside the slot.

[0015] The beneficial effects of the utility model are as follows:

[0016] 1. The utility model uses a heat preservation component that cooperates with a perovskite cell to absorb solar energy and convert it into electrical energy. The first conductor transmits the electrical energy to a storage battery for storage. The storage battery then transmits the electrical energy to a heating wire through a second conductor, heating the heating wire. This heats the air at the bottom of the partition. The hot air enters the box through the air guide hole, thereby keeping the takeout warm.

[0017] 2. The utility model provides an installation assembly. When the display screen needs to be disassembled or replaced, first pull the plug plate outward to separate it from the slot, and squeeze the limit rod to separate it from the limit hole, thereby releasing the limit on the limit rod. Pull the display screen outward to remove it, place the replaced display screen inside the placement slot, preliminarily limit it, and then cooperate with the elastic extrusion effect of the extrusion piece to push one end of the limit rod to engage with the limit hole, thereby installing and fixing the display screen, making it convenient to replace the display screen.
