A heat insulating device is arranged at the bottom of a box body, an air vent is arranged between inner and outer walls of the box body, the heat insulating device comprises an electric storage heating device and an auxiliary device, the auxiliary device is a container full of water, the upper part of the container is of an arc shape with an air vent, the electric storage heating device is an electric heater with a charging device and the heat insulating device is movably connected with the box body. Based on the technical scheme, the heat-insulating lunch box has the advantage of long heat insulating time.
Description
technical field [0001] The invention relates to a lunch box, in particular to a thermal insulation lunch box. Background technique [0002] At present, along with the raising of people's living standard, various household utensils have everything that one expects to find on the market. The lunch box is a household tool commonly used in the home, especially the thermal insulation lunch box, which is an indispensable thermal insulation tool in life. Most of the heat preservation lunch boxes now use the principle of heat preservation of the kettle to achieve the heat preservation effect. The so-called heat preservation lunch boxes are generally made of double-layer plastic or stainless steel plus a vacuum layer or a heat insulation layer. There is a cover on the top. It is tightly sealed, and the vacuum layer or heat insulation layer can delay the heat dissipation of the food contained inside, so as to achieve the purpose of heat preservation. The thermal insulation lunch box...
