Detailed Description
As shown in fig. 1 and 2: a self-heating lunch box comprises a box body 1 and a containing space 2 arranged in the wall of the bottom of the box body 1, wherein the wall of the box body 1 can be made of plastic or foam materials commonly used in the market. The bottom of the containing space 2 is fixed with a layer of breathable non-woven fabric 3, the containing space 2 is filled with self-heating powder, the used self-heating powder is made of materials such as iron powder, activated carbon, salt, vermiculite and water, and the self-heating powder can be the same as the self-heating powder of a warmer and can be the existing products in the market. The non-woven fabric 3 having air permeability is used to prevent the self-heating powder in the accommodating space 2 from leaking out. A plurality of apertures 4 communicating with the accommodating space 2 are further formed in the outer side of the bottom of the box body 1, and the apertures 4 are used for communicating the accommodating space 2 with the outside, so that air can enter the accommodating space 2 through the apertures 4 and react with self-heating powder. The sealing layer 5 that the bottom outside of box body 1 should be equipped with the one deck and should seal aperture 4, seals aperture 4 through sealing layer 5, prevents that external air from entering into accommodating space 2 in with self-heating powder material reaction, sealing layer 5 can use non-setting adhesive, sticky tape etc. to paste in the bottom outside of box body 1, seals aperture 4, also conveniently tears or breaks the hole during the use.
Wherein, preferably, still can set up the baffle 21 that divides into several regions with accommodation space 2 in the accommodation space 2, through setting up baffle 21, with the effectual several regions of dividing into of spontaneous heating powder in accommodation space 2, when spontaneous heating lunch-box turns on one's side or is falling over, the bottom of box body 1 that spontaneous heating powder in the inside all can the even distribution.
Preferably, a layer of tinfoil 22 is disposed at the connection between the upper part of the accommodating space 2 and the wall of the case, so that the bottom of the case 1 can be heated uniformly.
After the spontaneous heating powder is heated in a reverse and positive mode, iron powder contained in the spontaneous heating powder can also be oxidized into tri-gasified di-iron or tri-iron tetroxide and the like, so that the environment cannot be polluted.
