External circulation heating distribution box

Abstract

The invention provides an external circulation heating distribution box. The external circulation heating distribution box comprises a heat preservation box body, a heating system, an external circulation air exchange system, an upper door, an upper left storage chamber, an upper right storage chamber, a lower door and a lower storage chamber. The heating system comprises an aluminum plate fixing frame, an aluminum plate, a heating film, a heat isolation pad, an outer shell, a heating switch, a charging port, a temperature control switch, an exhaust fan I, an outer shell bottom plate, a cable and a battery. The external circulation air exchange system is arranged above the lower storage chamber and comprises a dustproof cover, an exhaust fan II, a fan cover, a USB cable and an exhaust fan II power supply. The technical problems that distribution boxes in the prior art are unreasonable in temperature structure, non-uniform in heating, insufficient in battery capacity and unlikely to guarantee the temperature and mouthfeel of food in the long-distance long-time distribution process are solved, and the external circulation heating distribution box achieves the technical effects of being reasonable in structure and uniform in heating and enabling distributed objects to keep fresh and good mouthfeel.

Description

technical field [0001] The invention relates to the technical field of distribution boxes, in particular to an external circulation heating distribution box. Background technique [0002] As we all know, food delivery plays a key role in the development of today's catering industry. A good food delivery service can not only establish a good brand image of the company, but also accelerate the demand for orders and promote the development of the company. In fact, it is very important to maintain the temperature and taste of food during food delivery, so people put a lot of energy into the design and production of delivery boxes for delivery. At present, the distribution boxes on the market include foam distribution boxes, waterproof cloth distribution boxes, plastic distribution boxes, metal material distribution boxes and so on. These distribution boxes generally rely on the heat preservation of the material itself and the distribution box structure itself to achieve the he...
