Detailed description of the invention

With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.

Embodiment 1

Such as Fig. 1, 2, 3, 4 one kinds of self-heating type lunch boxes, including back box 1, middleboxes 2, upper box 3 and lid 4, described middleboxes 2 is placed in back box 1, described upper box 3 is placed in middleboxes 2, described lid 4 covers on upper box 3, it is characterized in that, the inner chamber of box body 101 is divided into evaporating chamber 105 by being located at the diathermanous plate 102 within box body 101 and is used for placing the heating cabinet 104 of heating agent bag by the back box body 101 of described back box 1 from top to bottom, the cross section of described diathermanous plate 102 is semicircle, and the upper end of diathermanous plate 102 is provided with the leaking hole 108 evaporating chamber 105 and heating cabinet 104 turned on；

Being provided with support 203 in the middle box body 201 of described middleboxes 2, this support 203 is provided with the inner bag 202 for filling a bowl with rice, and the diameter of described inner bag 202 is less than the diameter of middle box body 201；

Described middleboxes 2 is identical with the structure of upper box 3.

nullDuring using，First by middleboxes 2、Upper box 3 separates with back box 1，Food is held in the inner bag 202 of middleboxes 2 and upper box 3，The most as shown in Figure 4 by heating agent bag by the bottom of described diathermanous plate 102 be provided with one be used in heating cabinet 104 place heating agent bag macropore put in heating cabinet 104，Owing to this macropore is sealed by shrouding 106 or opened，Described shrouding 106 is connected by torsion spring 107 is fixing with the side of macropore，Therefore before placement, first pass through chopsticks or miscellaneous part pressed for 106 times by shrouding，Macropore can be opened，Then heating agent bag is placed in heating cabinet 104，Due to the effect at torsion spring 107，After discharging heating agent bag，Decontrol shrouding，Shrouding 106 is under the effect of torsion spring 107，Macropore is closed，Then in evaporating chamber 105, heat a certain amount of water，The water yield not can exceed that the height of leaking hole 108，And the gravity adding water can not be more than the torsion power of torsion spring 107，Prevent from water from draining in heating cabinet 104 to react with heating agent in advance，After adding water to evaporating chamber 105，Middleboxes 2 and upper box 3 are sequentially placed in back box，Then lid is built；

nullWhen needs are had a meal，Shake lunch box，In lunch box back box 1, the water in evaporating chamber 105 is entered in heating cabinet 104 by leaking hole 108，React with the heating agent in the heating agent bag in heating cabinet 104，Owing to heating agent bag uses limestone，Limestone sends substantial amounts of heat after reacting to water，This heat passes through the diathermanous plate 102 of the higher aluminum of heat conductivity or copper one-tenth and is heated by the water on diathermanous plate 102，The steam that water after heating produces enters in middleboxes 2 and upper box 3 and heats for the food in middleboxes 2 and upper box 3，Utilization steam heats，Food does not haves the situation of exsiccation，Mouthfeel is the best，Environment can't be produced and pollute by the position carbon dioxide simultaneously generated after limestone reacts with water and calcium carbonate，During reaction，The water having most reacts the most completely，Reform into steam，This steam is entered in middleboxes 2 and upper box 3 by leaking hole 108，Owing to preventing steam from reacted impurity, food causing certain pollution，Steam in heating cabinet 104 is filtered by the filter cotton 109 added in leaking hole 108，Thermal source most utilizes the waste preventing heat.

By the present embodiment it can be seen that this utility model provide self-heating type lunch box, simple in construction, easy to use, pollution-free after reaction, and without power supply heat, environmental protection.

Embodiment 2

On the basis of embodiment 1, the upper surface of described back box 1 as shown in Figure 3 is provided with hook 103, the lower surface of described middleboxes 2 is provided with and links up with 103 pocket for the punch heads 204 coordinated, described back box 1 and middleboxes 2 and be stuck in by hook 103 reversal of the natural order of things that pocket for the punch head 204 is fixing to be connected.

The upper surface of described middleboxes 2 as shown in Figure 5,6 is provided with hook 103, and the lower surface of described upper box 3 is provided with and links up with 103 pocket for the punch heads 204 coordinated, described middleboxes 2 and upper box 3 and be stuck in by hook 103 reversal of the natural order of things that pocket for the punch head 204 is fixing to be connected.

By the explanation to accompanying drawing, it can be seen that in back box 1 and middleboxes 2；When middleboxes 2 and upper box 3 are attached, as long as by the pocket for the punch head bottom middleboxes 2 just on the hook in back box 1, in hook is completely installed in pocket for the punch head, then rotating middleboxes 2, the hook end of hook is left the notch of pocket for the punch head, is blocked by the notched wall of pocket for the punch head, achieve hook with pocket for the punch head with the use of, and then achieve back box and be connected with the fixing of middleboxes, middleboxes is identical with the connected mode of back box with middleboxes with the connected mode of upper box, is not describing in detail one by one.

Exemplified as above is only to illustration of the present utility model, is not intended that the restriction to protection domain of the present utility model, within the every and same or analogous design of this utility model belongs to protection domain of the present utility model.
