Abstract
The utility model relates to a lunch box capable of being heated. The lunch box capable of being heated is designed aiming at resolving the technical problem that heating and heat preservation of an existing similar lunch box are inconvenient. The lunch box capable of being heated comprises a box body and a box cover, and is characterized in that a sealing cavity is arranged inside the box body, the sealing cavity is filled with supersaturated sodium acetate solutions, and a metal piece capable of being twisted is arranged at the side wall of the sealing cavity. By means of the instability of the supersaturated sodium acetate solutions, slight oscillation generated when the metal piece is twisted enables solute in the supersaturated sodium acetate solutions to crystallize, an exothermic reaction is achieved, and generated heat plays a role in heating the lunch box and keeping the lunch box warm. The lunch box capable of being heated is simple in structure, reasonable in design, simple in heating and heat preservation operation, good in heating and heat preservation effect, and suitable for being used as a portable heat preservation lunch box or structural improvement of similar products.
Description
Technical field
The utility model relates to a kind of lunch box, but is a kind of lunch box capable of heating.
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, but the purpose of this utility model is that a kind of lunch box capable of heating 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.
But a kind of lunch box capable of heating, but should comprise box body, lid by lunch box capable of heating, its structural feature is to be provided with in the described box body annular seal space, filling supersaturated sodium acetate solution in the annular seal space, and the annular seal space sidewall is installed a sheet metal that can twist.Utilize the unstability of supersaturated sodium acetate solution, thereby when the distortion sheet metal, the slight vibrations that produce just can make the solute crystallization in the supersaturated sodium acetate solution, this is exothermic reaction, and the heat that produces can play heat tracing to lunch box.
Described box body is made of insulation skin and heat conduction internal layer, improves the heat tracing effect of lunch box.
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.
Description of drawings
Fig. 1 is sectional structure schematic diagram of the present utility model.
The name of sequence number is called among the figure: 1, box body, 2, lid, 3, sheet metal, 4, supersaturated sodium acetate solution.
The specific embodiment
Now by reference to the accompanying drawings, the utility model is further described.
As shown in Figure 1, but should comprise box body 1, lid 2, sheet metal 3 by lunch box capable of heating, box body is formed with annular seal space by insulation skin and heat conduction internal layer, and supersaturated sodium acetate solution 4 is housed in the annular seal space, and the annular seal space sidewall is installed a sheet metal that can twist.
During use, only need the distortion sheet metal, thereby make the solute crystallization in the supersaturated sodium acetate solution, become comparatively stable solid, the while release heat, this heat namely carries out heat tracing to lunch box.After the use, box body was positioned in the boiling water heating approximately 10 minutes, the just again dissolving of curdy solute becomes supersaturated sodium acetate solution, in order to recycle in the annular seal space.
Claims (2)
1. but lunch box capable of heating, but should comprise box body (1), lid (2) by lunch box capable of heating, it is characterized in that being provided with an annular seal space in the described box body (1), filling supersaturated sodium acetate solution (4) in the annular seal space, the annular seal space sidewall is installed a sheet metal that can twist (3).
