Abstract
A self-heating lunch box comprises a box cover (1), an inner container (2), and a housing (3), wherein an interlayer (4) is formed between the inner container (2) and the housing (3); the interlayer (4) is filled with a sodium acetate supersaturated solution; a convex ball (5) is disposed on the housing (3); a metal sheet (6) is disposed in the interlayer (4); one end of the metal sheet (6) is fixed in the inner container (2), and the other end contacts the convex ball (5) on the housing (3). When in use, the purpose of food heating is realized only by pressing the convex ball (5) to allow the metal sheet (6) to release heat through friction, then initiating a solution chain reaction to allow the solution to be crystallized rapidly so as to release a lot of heat. After use, the crystals absorb heat to become the sodium acetate solution again for next food heating. The utility model has the advantages of simple manufacture, low price, easy carrying, convenient operation, rapid heating, and suitability for repeated use.
Description
Technical field
The utility model relates to a kind of lunch box, relates in particular to a kind of lunch box that can heat voluntarily.
Background technology
The experience that much human all had food to cool off owing to various reasons, cold food not only are difficult to tripe down, and long-term eat cold rice, and health is had injury.Though heating tools such as micro-wave oven have been arranged in the market, because problems such as manufacturing materials and manufacture crafts, have all existed shortcoming such as cost an arm and a leg, not portable; Traditional incubation canteen has only the function of insulation, but can not cold food be heated; Existing from heat lunch box many with quick lime as the heat production material, each use all need be changed quick lime, complicated operation and cause waste.
Summary of the invention
The purpose of the utility model provide a kind of making simple, cheap, be easy to carry about with one, easy to operate, heating is rapid, repeatedly used from heating lunch box.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of from heating lunch box, comprise lid, inner bag and shell, wherein: form an interlayer between inner bag and the shell, protruding ball is arranged on the shell, sheet metal is arranged in the interlayer, an end of sheet metal is fixed on the inner bag, and the other end contacts with protruding ball on the shell; Be full of the sodium acetate supersaturated solution in the interlayer as the heat production material; Inner bag adopts the good stainless steel material of thermal conductivity, and shell adopts the relatively poor relatively rigid plastics of thermal conductivity, and protruding ball adopts elastomeric material.
The beneficial effect of the utility model is: make simple, cheap, be easy to carry about with one, easy to operate, heating rapidly, can use repeatedly.
Description of drawings
Figure is the structural representation of the utility model.
Drawing explanation: 1. lid 2. inner bags 3. shells 4. interlayers 5. protruding ball 6. sheet metals
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to specify, but is not restriction the utility model:
With reference to accompanying drawing; The utility model comprises lid (1), inner bag (2) and shell (3), wherein forms interlayer (4) between inner bag (2) and the shell (3), is full of the sodium acetate supersaturated solution as the heat production material in the interlayer (4); Protruding ball (5) is arranged on the shell (3); Sheet metal (6) is arranged in the interlayer (4), and an end of sheet metal (6) is fixed on the inner bag (2), and the other end contacts with protruding ball (5) on the shell (3).Inner bag (2) adopts the good stainless steel material of thermal conductivity, and shell (3) adopts the relatively poor rigid plastics of thermal conductivity, and protruding ball (5) adopts elastomeric material.Because supersaturated solution has more solute, is in the steady state of unsettled Jie, when receiving some stimulation, this state can disequilibrium.During use, only need push protruding ball (5), make sheet metal (6) because of the friction evolution of heat; The sodium acetate supersaturated solution that closes on is met thermal coagulation and is continued to emit heat simultaneously, makes solution chain-react on every side, and then makes the rapid crystallization of solution; Become than stable solid; This process can be emitted great amount of heat, and heat passes to the food in the lunch box through the good inner bag of thermal conductivity (2), thereby reaches the purpose of heat food.After finishing using, only need that lunch box is put into hot water about 80 ℃ and soak or wherein crystal is absorbed heat again and become SAS, be used for the use of next heat food.
Claims (3)
1. one kind is heated lunch box certainly; Comprise lid (1), inner bag (2) and shell (3); It is characterized in that: form interlayer (4) between inner bag (2) and the shell (3), protruding ball (5) is arranged on the shell (3), sheet metal (6) is arranged in the interlayer (4); One end of sheet metal (6) is fixed on the inner bag (2), and the other end contacts with protruding ball (5) on the shell (3).
2. according to claim 1 from heating lunch box, it is characterized in that: interlayer is full of the sodium acetate supersaturated solution in (4).
3. according to claim 1 from heating lunch box, it is characterized in that: inner bag (2) adopts the good stainless steel material of thermal conductivity, and shell (3) adopts the relatively poor relatively rigid plastics of thermal conductivity, and protruding ball (5) adopts elastomeric material.
