The utility model content
The purpose of the utility model is to provide a kind of electric heating thermal insulation lunch box bag of high insulating effect, and can not change the taste of food in the lunch box, thereby reduces the pollution of using disposable lunch box to bring.
A kind of electric heating thermal insulation lunch box bag is provided with heat-insulation layer in the lunch box bag, between lunch box bag wall and the heat-insulation layer or between heat-insulation layer and the heat-insulation layer electric heating piece is installed, and power line links to each other with electric heating piece and can stretch out the lunch box bag and link to each other with power supply.
Adopt the described electric heating thermal insulation lunch box of the utility model bag, lunch box is placed in the lunch box bag, in the bag wall of lunch box bag heat-insulation layer is arranged; Can reduce scattering and disappearing of heat in the lunch box own; When the user arrives the workplace, can connect power supply through power line easily, make the electric heating piece work in the lunch box bag; Release heat is kept temperature-resistant in the lunch box bag.Compare with existing general lunch box bag, it is not only easy to use, and can be well to meal insulation, and through test, it can keep temperature to 36 degree-70 degree in the lunch box bag under the plug-in heated condition, make the food that is contained in the lunch box keep tasty.Equally for chilled food; Because the insulation layer of this product can effectively stop the outside heat of lunch box bag to get in the bag; Under situation about not heating, even also can let food remain on freezing state in the summer of sweltering heat, the tenability time of its temperature reaches 4-8 hour.Therefore, this product can reduce the edible disposable snack box of user to a certain extent, reduces the environmental pollution that is brought.
Preferably, said lunch box bag comprises loam cake and lower cover, and loam cake and lower cover can be opened or tight closure through slide fastener, and said going up between tegmental wall and the heat-insulation layer and/or between following tegmental wall and the heat-insulation layer also can be provided with electric heating piece.
Preferably, the top of said lunch box bag or sidepiece are provided with handle.
Preferably, the power line that links to each other with electric heating piece is that USB interface can be connected power supply with computer USB interface.
The electric source line interface that links to each other with electric heating piece also can be complementary with the vehicle charging seat, adopts the vehicle charging seat to supply power.Also can link to each other, adopt alternating current to supply power with ac plug.
Preferably, said lunch box bag also is provided with receiving room or the collecting bag of taking in power line.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Like Fig. 1, Fig. 2 and shown in Figure 3; The utility model electric heating thermal insulation lunch box bag; In the bag wall of lunch box bag 1, be provided with heat-insulation layer 2; Between lunch box bag bag wall 11 and 2 of heat-insulation layers or heat-insulation layer 2 and heat-insulation layer, electric heating piece 3 is installed, power line 4 links to each other with electric heating piece 3 and can stretch out the lunch box bag and link to each other with power supply.
When lunch box being placed in the lunch box bag, in the bag wall of lunch box bag heat-insulation layer is arranged, can reduce scattering and disappearing of heat in the lunch box own; When the user arrives the workplace, can connect power supply through power line easily, make the electric heating piece work release heat in the lunch box bag; Keep the temperature in the lunch box bag, compare with existing general lunch box bag, it is not only easy to use; And can well be incubated lunch box; Make the food that is contained in the lunch box tasty, and can reduce the edible disposable snack box of user to a certain extent, reduce the environmental pollution that is brought.
