Description
Technical field
The utility model relates to a kind of lunch box, is a kind of one-time heating lunch box.
Background technology
But lunch box is a kind of box of splendid attire food, and range of application is wider; More existing lunch boxes generally are made of the insulation material, but this kind lunch box is not high cost, is exactly that heat insulation effect is not good enough, undesirable.For this reason, Granted publication CN202035618U such as the Chinese patent literature publication, November 16 2011 Granted publication day, the utility model name is called " heated heat-preserving lunch box ", its primary structure is to comprise the incubation canteen of an engineering plastics system, the wall of incubation canteen has bilayer, and the bottom of incubation canteen has heating wire.This kind lunch box is namely by electrically heated mode, to the lunch box heat tracing; But it uses comparatively inconvenience, need to be with electric energy as the energy.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is that a kind of one-time heating lunch box is provided to this area, makes it solve the comparatively technical problem of inconvenience of existing similar lunch box heat tracing.Its objective is and be achieved through the following technical solutions.
This one-time heating lunch box comprises box body, lid, and its structural feature is to be provided with inner chamber in the described box body, intracavity bottom filling quick lime, and the inner chamber sidepiece is provided with a water bag, and described box body lateral wall is provided with the pin hole corresponding with described water bag.But be somebody's turn to do the principle that lunch box capable of heating utilizes water and quick lime exothermic heat of reaction, lunch box is carried out heat tracing, its use is comparatively convenient.
Described box body is made of insulation skin and heat conduction internal layer, and its heat tracing effect is better.
The thimble of the external disjunctor of described box body.Thimble is used for piercing through water bag by the pin hole of box body, makes the reaction of water and quick lime, looks in addition the loaded down with trivial details of thimble thereby remove from.
The utility model is simple in structure, and is reasonable in design, and heat tracing is simple to operate, effect is better, and be suitable as Portable thermal insulation dinner pail and use, or the architecture advances of like product.
