With the improvement of the living standard of people, more and more people begin to pay attention to diet health, and more people begin to carry self-made convenience for work and study, which is economical, practical, healthy and nutritious, so that the lunch bag is basically one of necessities for work and life. In China, the requirements of the public on catering food are meat and vegetable matching and complete color and flavor, which means that the requirements on fresh-keeping storage and secondary heating treatment of the catering food are higher. At present, for carrying catering food, diners mostly take the traditional lunch bag and the lunch bag with single refrigeration function as main carrying tools. Because the traditional lunch bag generally adopts the principle of physical heat insulation and does not have the functions of preserving freshness and secondarily heating the food, the food is easy to deteriorate when being stored for a long time or the taste and the health of the food are influenced when being taken. Most of the conventional lunch bags with the functions of refrigerating and refreshing food in the market utilize ice bags or a physical cooling mode of enhancing the airtightness of the lunch bags by adopting special materials to realize the refrigeration and refreshing of the food. When the lunch bag is used, the food can be refrigerated and kept fresh only in a short time, and the carried food cannot be heated when a diner has a meal, so that the diner can only eat cold meal to influence the body health of the diner, or the diner needs to heat the food by using other cookers, thereby wasting time and labor.

The temperature sampling device has the functions of storing food, insulating heat and fixing the power supply assembly (A1), the drive controller (A2), the human-computer interface (A3), the temperature sampling unit (A4) and the semiconductor cold-hot plate (A5). The handle (A7) is formed by sewing waterproof fabric and pearl wool material and is arranged at the outer side of the bag cover (A6-2) so as to be convenient for carrying the automatic intelligent temperature control lunch bag in a hand. The shoulder strap (A8) is composed of the adjusting buckle (A8-1) and the nylon braid (A8-2) and is arranged at the side wall (A6-3) so as to be convenient for carrying the automatic intelligent temperature control lunch bag in a back-to-back spanning manner. The power supply module (A1) is composed of the high-frequency switching power supply (A1-1), the lithium battery (A1-2) and the power management module (A1-3), is installed at the bottom of the side wall (A6-3), and provides electric energy for the driving controller (A2), the human-computer interface (A3), the temperature sampling unit (A4) and the semiconductor cold-hot plate (A5) and monitors the working state of the lithium battery (A1-2). The driving controller (A2) is composed of the microcontroller system (A2-1) and the power full-bridge circuit (A2-2), is installed in the middle of the side wall (A6-3), provides controllable and reversible electric energy for the semiconductor cold and hot plate (A5) to drive the semiconductor cold and hot plate (A5) to work, so that the semiconductor cold and hot plate meets the requirements of corresponding working strength and working mode, and exchanges data with the human-computer interface (A3). The human-computer interface (A3) is composed of the display screen (A3-1) and the keyboard (A3-2), is arranged outside the pocket cover (A6-2) and is used for displaying data and setting parameters. The temperature sampling unit (A4) consists of the thermoelectric sensor (A4-1) and the auxiliary device (A4-2), collects the temperature information in the bag of the automatic intelligent temperature control lunch bag, transmits the temperature information to the driving controller (A2), and is arranged at the upper part of the side wall (A6-3). The semiconductor cold and hot sheet (A5) is an executive device for converting electric energy into heat energy and is arranged at the inner side of the bag bottom (A6-1).
The specific working process is as follows:
after food is placed into the automatic intelligent temperature control lunch bag, a user covers the bag cover (A6-2), and then the working mode of the automatic intelligent temperature control lunch bag is set by using the human-computer interface (A3), wherein the working mode can be divided into a cold-hot mode and a heat-preservation mode, and the time setting can be accurate to minutes. In the cold and hot mode, the driving controller (A2) drives the semiconductor cold and hot plate (A5) in a forward current mode according to a preset program, the semiconductor cold and hot plate (A5) cools and cools the stored food and drink, when the time for leaving the predicted meal is short (the time can be set through the human-computer interface (A3)), the driving controller (A2) drives the semiconductor cold and hot plate (A5) in a reverse current mode according to the preset program, the semiconductor cold and hot plate (A5) heats and heats the stored food and drink, and when the temperature reaches a preset temperature, the constant temperature mode is carried out to keep the temperature of the stored food and drink at a preset value so as to facilitate the meal. In the process, the driving controller (A2) reads the temperature of the inner space of the bag body (A6) through the temperature sampling unit (A4) in real time to adjust the driving current of the semiconductor cold and hot sheet (A5) to carry out intelligent regulation, so that the optimal fresh-keeping and heat-preserving effect is achieved. In the heat preservation mode, the driving controller (A2) reads the temperature of the inner space of the bag body (A6) through the temperature sampling unit (A4) and compares the temperature with a set temperature, and the difference determines the driving current direction of the driving controller (A2) to the semiconductor cold-hot plate (A5), so that the semiconductor cold-hot plate (A5) is in a heat-generating temperature-rising or cooling state. The difference value between the temperature of the inner space of the bag body (A6) and the set temperature is taken as a target to be zero by adopting a control algorithm of intelligent approximation. In the above two operation modes, the preset temperature can be freely set within an allowable range.
