Abstract

The utility model discloses an automatic heating lunch box which mainly comprises a box body and a box cover, wherein the box body comprises an outer layer box body and an inner layer box body, and the outer layer box body and the inner layer box body are fixedly connected; the outer layer box body is internally provided with an electric heating wire, and one side of the outer layer box body is provided with a power input port; the power input port is electrically connected to the electric heating wire; and the other side of the outer layer box body is provided with a control switch. When the automatic heating lunch box is used, the automatic heating lunch box is energized through the power input port, and a switch control key at one side of the outer layer box body is turned on; after the electric heating wire is energized, the electric heating wire is gradually heated up, and food in the inner layer box body is heated through the heating of the electric heating wire; when the temperature of the inner layer box body reaches a certain temperature, the electric heating wire is maintained to be in a constant temperature state without being heated any more; and after the automatic heating lunch box is finished being used, the switch control key is turned off to cut off the power. Due to the adoption of the technical scheme, the automatic heating lunch box disclosed by the utility model has the advantages of simple structure, environmental protection, sanitation, convenience in use and the like.

Description

Automatically heat lunch box
Technical field
The utility model relates to a kind of daily living article, particularly a kind of lunch box that can heat automatically.
Background technology
The Along with people's growth in the living standard, the outing of going out are more and more with movable chance, during the much human outside eating; Use disposable lunch box and chopsticks; Not only wasted but also not environmental protection,, can not realize not only environmental protection but also effect easily if the common packed meal that carries also needs electricity, gas or coal heating.
Summary of the invention
The utility model provides a kind of not only environmentally-friendly sanitary but also automatic heating lunch box easy to use to the existing in prior technology defective.
The automatic heating lunch box of the utility model; Comprise a box body and a lid; Said box body comprises an outer box body and an internal layer box body, between said outer box body and said internal layer box body, is provided with heating wire, and a side of said outer box body is provided with a power supply input port; Said power supply input port is electrically connected on said heating wire, and the opposite side of said outer box body is provided with a gauge tap.
When going out to need heat food, at first give heating lunch box energising automatically through the power supply input port, open the switch operating key of outer box body one side; Heating wire heats up after energising gradually; Thereby because the electrothermal wire heating heats the food in the internal layer box body, when reaching uniform temperature in the internal layer box body, heating wire will keep temperature constant state; After using, close the switch operating key and cut off the electricity supply.
Owing to adopt above technical scheme, that the automatic heating lunch box of the utility model has is simple in structure, environmentally-friendly sanitary and advantage such as easy to use.
Description of drawings
Fig. 1 is the structural representation of the automatic heating lunch box of the utility model.
The specific embodiment
For the benefit of, describe below in conjunction with accompanying drawing and embodiment to the understanding of the structure of the automatic heating lunch box 1 of the utility model.
In conjunction with shown in Figure 1, the automatic heating lunch box 1 of the utility model mainly comprises a box body 10 and a lid 11; Box body 10 comprises an outer box body 101 and an internal layer box body 102, and outer box body 101 is fixedly connected with the upper end of internal layer box body 102, and outer box body 101 surrounds internal layer box body 102; Internal layer box body 102 is in order to deposit food; The height of internal layer box body 102 is less than the height of outer box body 101, and therefore between outer box body 101 and internal layer box body 102, having formed an accommodation space 12 puts heating wire 13, and a side of outer box body 101 is provided with a power supply input port 14; Power supply input port 14 is electrically connected on heating wire 13; The opposite side of outer box body 101 is provided with a gauge tap 15, and in order to the conducting of control heating wire 13 electric currents, outer box body 101 can be all circle, square or other shape with internal layer box body 102; Indoor design also can be multi partition, and is more convenient and practical.
When the needs heat food, at first connect external power source, through the electric current of gauge tap 15 conducting heating wire 13 through power supply input port 14; Heating wire 13 heats up after energising gradually, thereby because the food in the internal layer box body 102 is heated in heating wire 13 heatings, when reaching uniform temperature in the internal layer box body 102; Heating wire 13 will keep temperature constant state no longer to heat; After using, closing control switch 15 is also cut off the electricity supply, and just can accomplish operation this time.Because outer box body 101 is all processed by insulating materials with internal layer box body 102, environmentally-friendly sanitary not only when therefore using, but also safe ready.
More than combine accompanying drawing embodiment that the utility model is specified, those skilled in the art can make the many variations example to the utility model according to above-mentioned explanation.Thereby some details among the embodiment should not constitute the qualification to the utility model, and the scope that the utility model will define with appended claims is as the protection domain of the utility model.
