The invention discloses a portable heating lunch box. The lunch box comprises an energy storage chamber, heating wires and an outer sealing cover, wherein a lithium battery is arranged in the energy storage chamber; a water storage tank is arranged above the energy storage chamber; the heating wires are arranged on the bottom side of the inner part of the water storage tank; a supporting bracket is arranged above the inner part of the water storage tank; an inner container is inlaid in the center of the water storage tank; a clamp is arranged on the side surface of the inner container; the outer sealing cover is inlaid in the upper portion of the water storage tank; a connecting shaft is connected with two sides of the outer sealing cover; a connecting sleeve is arranged below the middle part of the outer sealing cover, a telescopic rod is inlaid in the connecting sleeve, and a spring is installed between the telescopic rod and the connecting sleeve. According to the portable heating lunch box, the lunch box can be repeatedly utilized, food is prevented from being heated by adopting chemical reaction principles, water vapor generated by heating water can be sprayed out through airholes, the sprayed water vapor heats food in dishes, and the food is heated more uniformly.
Description
technical field [0001] The invention relates to the technical field of small household appliances, in particular to a portable heating lunch box. Background technique [0002] With the development of science and technology, people's lives are becoming more and more prosperous, and small household appliances are constantly being improved and innovated to meet the needs of the market. Nowadays, people's life and work pressure are gradually increasing. When working, people often use lunch boxes to prepare their own meals, but most of the lunch boxes with heating function on the market are not easy to use, the heating is not uniform enough, and the principle of chemical reaction is used to heat the meals. The chemical reactants are disposable products, which are harmful to the environment. Harm is caused, and the cost of using it at the same time is relatively high. Therefore, in view of the above problems, it is necessary to improve on the basis of the original equipment to mee...
