The box body is provided with an inner tank, the heating base 10 is provided below the box body, a heating element is provided inside the heating base 10, and the box body can be heated after power is turned on. The upper cover 7 is provided above the box body and is connected to the box body through a second buckle 13.

[0028] The heating base 10 includes a heating plate 21 and a heating element fixing frame 22. The heating element is arranged in the heating plate 21, which is a heating resistance wire. The heating plate 21 is rectangular, and a heating element fixing frame 22 is fixed on the outside. A control circuit is also arranged in the heating plate to control the switching state of the heating element. A Hall sensor 23 is also arranged in the heating element fixing frame 22. The Hall sensor 23 is connected to the control circuit to detect whether the box body is placed on the heating plate.

[0029] The bottom surface of the box body is fixedly connected with a base bracket 24, the upper surface of the base bracket 24 is an annular plane 241, the side surface is an outwardly inclined inclined surface 242, the cross section of the base bracket 24 is a trapezoid, and the cross section of the heating element fixing frame 22 is also a trapezoid. When the base bracket 24 is placed on the heating base, the inner wall of the side surface fits the outer side surface of the heating element fixing frame 22, which plays a role in limiting. The heating element fixing frame 22 is made of magnetic material, and a magnet 25 is provided in the base bracket 24 for convenient pre-positioning.

[0030] The electric lunch box adopts a double-layer box structure, including an upper box body 4 and a lower box body 1. The lower box body 1 is provided with a bottom liner 3, and the upper box body 4 is provided with an upper liner 5. The top of the lower box body 1 has an opening, and the edge of the opening is provided with a first step portion 15. The upper box body 4 is arranged on the first step portion 15, and an annular groove is provided at the bottom of the upper box body 4. The annular groove and the first step portion 15 match to make the outer side surfaces of the upper box body 4 and the lower box body 1 smooth, and the sealing effect is also better.

[0031] The lower box body 1 is also provided with a second step portion 14, which is below the first step portion 15, and the bottom liner 3 is arranged on the second step portion 15. A heat preservation layer 2 is also arranged between the bottom liner 3 and the lower box body 1, and the heat preservation layer 2 can be a heat preservation foam, such as polystyrene (EPS), polyurethane (PU), polyethylene (EPE), etc. The bottom surface of the upper box body 4 is provided with a steam through hole 41, and a support block 42 is arranged in the gap of the steam through hole 41, and the upper liner 5 is arranged on the support block 42.
