Description
Technical field
The utility model relates to a kind of tableware, relates in particular to a kind of lunch box.
Background technology
As everyone knows, lunch box is people's one of crucial tablewares in the process of having a dinner, and existing lunch box is varied; But be the improvement on material, pattern and size mostly, do not have outstanding improvement on the function, existing lunch box adopts inner bag to be incubated basically; But the time is longer; Food in the lunch box still can cool off, and along with improving constantly of living standard, existing lunch box can not satisfy people's user demand.
Summary of the invention
The purpose of the utility model is to provide a kind of pattern novel, and simple structure is convenient and practical, and simple operation is made simple and easyly, is more suitable for the incubation canteen of popular use.
The utility model comprises box body, base, insulating heat-conductive plate, resistance wire, rechargeable battery and switch; Box body is the upper shed trench structure, and square open-work is offered in the bottom surface of box body, the affixed insulating heat-conductive plate of through-hole position; The affixed hollow base in the bottom of open-work; The inside of base is provided with resistance wire, and resistance wire and rechargeable battery, switch are composed in series circuit, and wherein the charge port of rechargeable battery and switch are separately positioned on the outside of base.
During use, the inner resistance wire of base can heat the food of box body inside, owing to be separated by through the insulating heat-conductive plate between base and the box body, then heat passes to the inner food of box body by the insulating heat-conductive plate, in addition also to the resistance wire insulation of base inside; Resistance wire passes through the rechargeable battery supply, and through switch control.
The utility model compared with prior art has following advantage: pattern is novel, and simple structure is convenient and practical, and simple operation is made simple and easyly, is more suitable for popular use.
