Problems solved by technology
[0002] With the progress of society, the pace of life of working people is getting faster and faster, and the pace of life is getting more and more tense, leaving less and less time for personal rest, resulting in no time to make lunch by yourself, takeaway box lunch is unhygienic, and it is economical to eat in restaurants. The pressure is relatively high, and at the same time, it is difficult to find a restaurant that suits your taste. Therefore, you need to use a lunch box to pack a pre-made lunch and bring it to the office for lunch
[0003] At present, the existing lunch boxes cannot adjust and control the temperature. In the hot summer, if the food is placed in the lunch box, it will soon deteriorate. At the same time, most of the heating methods are heated at the bottom of the lunch box. Paste, the nutrition is destroyed, affecting the taste of eating

The invention discloses a portable lunch box capable of heating and cooling. The portable lunch box capable of heating and cooling comprises a box body and a box cover, wherein an insulation cover isarranged inside the box body; a rotating wheel is arranged on the right side above the box body; a refrigerant box is arranged inside the box cover; the bottom of the refrigerant box is connected witha copper tube; a sealing ring is arranged inside the box cover; a heat-resistant guide tube is arranged inside the box cover; a one-way air valve is arranged at one end, which penetrates out of the upper surface of the box cover, of the heat-resistant guide tube; and fasteners are arranged on the right sides of the box cover and the box body. According to the portable lunch box disclosed by the invention, direct current is rectified into alternating current by utilizing an inverter, foods are uniformly heated by utilizing an eddy current effect of electromagnetism, the heating speed is increased, and the effects of refrigerating and retaining freshness are achieved by matching the refrigerant and ice bag. The copper tube is set to be S-shaped, and fins are arranged on the surface of the copper tube, so that the cooling speed is increased, the heating and cooling speed is increased, and the original freshness of the foods is ensured.
