Portable heated lunch box

Abstract

A portable heated lunch box comprises a housing, an intermediate housing, a liner, a battery, a heating tube, a heat-conducting plate, a temperature sensing module and a control module. The intermediate housing is sleeved inside the housing, and the liner is sleeved inside the intermediate housing; the battery, the heating tube and the heat-conducting plate are arranged between the bottoms of the housing and the intermediate housing, the heat-conducting plate fits with the bottom of the intermediate housing, the heating tube comes in contact with the heat-conducting plate for heat conduction, and the battery, the heating tube and the temperature sensing module are electrically connected to the control module. The internal components are compactly arranged, and external power supply is not required for heating. The temperature sensing module is close to the heating area. A display module ensures intuitive monitoring of heating temperature, remaining battery level and heating duration.
