With the development of modern society, people have more and more demands for portable food in the processes of learning, working, traveling and the like. While enjoying the delicacy of portable foods, food safety concerns continue to be raised. The portable food mainly comprises industrial packaged food (such as instant noodles), take-out catering and self-made food. The industrial packaged food needs a long shelf life, food additives such as preservatives and the like are often used, and the eating of the food is too much and is not beneficial to the health of people. With the rapid development of the logistics industry, take-out restaurants are favored by more and more people, but the take-out restaurants are numerous, uneven and scattered in distribution, the supervision of government departments is difficult, the food selection and sanitation are difficult to guarantee, and the take-out restaurants use various disposable tableware, so that the food safety hidden danger is further increased. Therefore, homemade portable food is still a more ideal choice.
The heat preservation lunch-box is that self-control portable food needs to use main storage instrument. Common heat-preservation lunch boxes on the market mainly comprise a common heat-preservation lunch box and a heatable heat-preservation lunch box. Patent CN201520742402.9 proposes a portable mobile heating lunch box, which is provided with a rechargeable battery pack and a control module, and can regulate temperature; patent CN201720831728.8 proposes a heating lunch box, in which a rechargeable battery and a controller are arranged, and a solar energy absorbing device is arranged on the outer wall, which can be charged by solar energy; patent CN201720696882.9 proposes a portable self-heating lunch box, which is provided with a battery pack and a circuit control board, and can heat dishes and soup by its own electricity storage function. Patent CN201820295504.4 provides a steam self-heating lunch-box, is equipped with baffle, heat preservation inner wall, places the space in the box with the meal and rationally classifies, improves the heating effect.
Therefore, the existing heat-preservation lunch box has two functions of heat preservation and heating. The recent invention makes some improvements to the heat-insulating lunch box, and mainly focuses on changing the heating energy, form and efficiency. However, the heat-preserving lunch box cannot change the fact that food can deteriorate after being placed for a certain time, and the deteriorated food can cause damage to the body if being eaten by mistake. If a food safety monitoring system can be established in the heat preservation lunch box, the damage caused by eating deteriorated food by mistake can be avoided.
