Abstract
The utility model discloses an electrothermal lunch box which is composed of a lunch box cover and a lunch box body, wherein the bottom of the lunch box body is provided with a heat conducting plate, and an electrothermal element connected with the heat conducting plate is arranged below the heat conducting plate. The electrothermal element is at least one PTC (Positive Temperature Coefficient) heater. The edge of the lunch box cover is overturned toward the inner side and is pressed into a sealing ring in a die casting mode, and the side of the bottom of the lunch box body is provided with a power socket which is in matched connection with the built-in electrothermal element. By adopting the PTC heater, the electrothermal generator of the utility model has the advantages of automatic constant temperature, electricity saving and high safety. The inner side on the lunch box cover is provided with the sealing ring, therefore, the electrothermal lunch box can preserve heat well when in not heating. A power socket cover is covered on the power socket to prevent water from entering a plug and prevent dust sundries from invading.
