Further, in the description of the present invention, "a plurality" means two or more unless there is an explicit specific limitation; "multiple sets" means two or more sets unless specifically limited;

as shown in fig. 1-4, the present invention provides a solution that includes a reusable fixation member and a disposable member.

The fixing member includes an outer box 1, a top partition 2, and a box cover 3. Follow outer box bottom edge is provided with end skirt 7, end skirt 7 encloses synthetic air insulating layer jointly with the lunch-box at the bottom of placing the plane and outer box to avoid the high temperature that self-heating lunch-box produced to scald bad or scald the lunch-box and place the plane, and air insulating layer also plays the heat preservation effect to self-heating lunch-box, reduces thermal conduction loss, has improved the thermal efficiency of heating food. Along the inner wall of the outer box, water adding scales are marked upwards from the edge of the bottom of the outer box. When the water heater is used, the water quantity with the corresponding scales is poured, and the heating bag with the corresponding scale model is put into the water heater, so that the heating bag is matched with the poured water quantity. The top partition plate is provided with a plurality of holes, and heated steam can pass through the holes from the bottom of the self-heating lunch box to reach the heating space on the upper part of the partition plate. And a vertically downward box cover skirt is arranged along the top edge of the box cover. The box cover skirt can tightly hoop the top edge of the outer box and can move up and down, so that the box cover, the box cover skirt and the top partition plate enclose a heating accommodating space with variable height.

The disposable component comprises a first inner case 4, a second inner case 5, a heating pack 6; the food in the first inner box and the food in the second inner box can be the same or different. The first inner box may be, but is not limited to, a hermetically packaged food item. The second inner box can also be but is not limited to food in sealed package, soup in soft package, beverage and the like. The heating bag is made of chemical materials which are commonly used in the field and have exothermic reaction after being contacted with water, wherein the chemical materials include but are not limited to quicklime and the like, and the heating bag can generate exothermic reaction when being contacted with water and can generate high-temperature steam at 150 ℃.

When the fixing component is matched with a set of disposable components for storage (hereinafter referred to as one-to-one), the top clapboard is placed at the top of the outer box, the box cover is tightly buckled on the outer box, and the top of the box cover is tightly attached to the top edge of the outer box, so that the combined volume is minimized. The corresponding set of disposable components can be placed in the outer box or can be stored separately.

When one set of fixing component and a plurality of sets of disposable components are stored in a matching way, the combination of the fixing components is the same as the one-to-one combination, the plurality of sets of disposable components can be stored in a set respectively, and can also be stored respectively according to the types of the components, and one set of disposable components can be placed inside the outer box.

When only one heating and containing space is used for heating food, the operation steps are as follows: pouring water with corresponding water volume scales into the outer box, then putting the heating bag with corresponding scales into the outer box, then putting the first inner box 4 filled with food (if the food in the inner box is sealed and packaged by a film, the film needs to be removed in advance, the same applies hereinafter), and then tightly covering the box cover. The heating bag can heat the food in the first inner box by high-temperature water vapor generated by exothermic reaction when meeting water.

When the two containing spaces are used for heating food at the same time, the operation steps are as follows: and pouring water with corresponding scales into the outer box, putting the heating bag with the water volume scales corresponding to the water volume, putting the first inner box filled with food, putting the top clapboard on the top of the outer box, putting the second inner box filled with food on the top clapboard, and tightly covering the box cover. The heating bag heats the food in the two containing spaces simultaneously by high-temperature water vapor generated by exothermic reaction when meeting water. It should be noted that the first inner case and the second inner case may contain food directly sealed and packaged in the inner case by the film, or may contain food additionally placed in the inner case, and may be, but not limited to, soft package or pre-processed food such as dish, soup, porridge, beverage, etc.

The above-described embodiments of the present invention can be arbitrarily combined and combined if not obviously contradictory or based on one embodiment. The embodiments and specific parameters in the embodiments are only for clearly expressing the implementation process of the present invention, and are not used for limiting the patent protection scope of the present invention (the patent protection scope of the present invention still depends on the patent claims).
