With the development of the food delivery industry and the expansion of the food delivery radius, the heat preservation function of the traditional food delivery box alone cannot meet the needs of the existing market. Due to the long distance and long delivery time, the temperature of the food delivered to customers often cannot reach the customer requirements, resulting in more and more complaints. On the other hand, the existing takeaway boxes on the market are too single in function, can only keep warm or refrigerated, and cannot satisfy the simultaneous distribution of high-temperature food and low-temperature food. In addition, the traditional heating box takeaway box needs to be heated before each use, which is time-consuming and power-consuming, and cannot meet the needs of food delivery at any time.
