Heating and heat-preserving lunch box

Abstract

The invention discloses a heating and heat-preserving lunch box which comprises a box body, a box cover and a rotating shaft connected with one end of the box cover, and further comprises a storage battery, an electric heating plate, a cushion layer, a switch, a thermometer and a display, wherein the storage battery and the electric heating plate are both arranged at the lower end of the box body; the switch is arranged on one side surface of the box body; the cushion layer is arranged at the lower ends of the storage battery and the electric heating plate; the storage battery is connected with the electric heating plate through the switch; the thermometer is arranged on the inner side of the box cover; the display is arranged on the outer side of the box cover and respectively connected with the thermometer and the storage battery. According to the heating and heat-preserving lunch box disclosed by the invention, the storage battery is used for supplying power to the electric heating plate, the lunch box can be heated after the switch is turned on, the heat preservation effect of the lunch box is improved, and stored food is prevented from being cooled.

Description

technical field [0001] The invention discloses a heating and heat preservation lunch box, which relates to the technical field of tableware manufacturing. Background technique [0002] Lunch box is a kind of commonly used tableware, which is often used in daily life. When the weather is cold, the food stored in the lunch box cools down quickly, which affects the taste of the food. Most of the design and production of thermal insulation lunch boxes in the prior art are to improve thermal insulation materials and specific structures. Few of the lunch boxes themselves provide the design of heating devices. Even some thermal insulation lunch boxes combined with heating devices have complex structures. Unsatisfactory heating effect, inconvenient use and other defects. Simultaneously, since the user usually cannot judge the internal temperature of the thermal insulation lunch box only by the appearance, it brings further inconvenience to the use.

When the weather is cold, the food stored in the lunch box cools down quickly, which affects the taste of the food

Most of the design and production of thermal insulation lunch boxes in the prior art are to improve thermal insulation materials and specific structures. Few of the lunch boxes themselves provide the design of heating devices. Even some thermal insulation lunch boxes combined with heating devices have complex structures. Unsatisfactory heating effect, inconvenient use and other defects

Simultaneously, because the user usually can't judge the inner temperature of the thermal insulation lunch box only by the appearance, it brings further inconvenience to the use.
