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.
[0026] 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 hole 41, and a support block 42 is arranged in the gap of the steam hole 41, and the upper liner 5 is arranged on the support block 42. Support plates are arranged on the four corners of the upper edge of the upper liner 5, and a steaming dish plate 6 is arranged on the support plate, and a cylindrical handle 9 is arranged on one side of the outer side of the lower box body 1. The lower box body 1 and the upper box body 4 are connected by a first buckle 12.
[0027] The upper cover 7 is connected to the upper box body 4 through the second buckle 13. The bottom edge of the upper cover 7 is also provided with an annular groove, which covers the upper box body 4, so that the surface of the entire electric lunch box is smooth and flat. The upper cover 7 is provided with an air outlet 71, which is a vertical pipe structure. The air outlet 71 is connected to a gas collector, which includes a gas collecting shell 8 and an exhaust pipe 11. The gas collecting shell 8 is a horizontal tube, with a right end bent, and a gas collecting channel is provided inside. The exhaust pipe 11 is connected to the left end of the gas collecting shell 8 and communicates with the gas collecting channel. A gas collecting nozzle 73 connected to the gas outlet 71 is provided at the bottom of the right end bend of the gas collecting shell 8, and a groove is provided at the top of the gas outlet 71. The gas collecting nozzle 73 is spherical and is clamped with the groove at the top of the gas outlet 71. A check valve 72 is provided inside the air outlet 71. The check valve 72 includes a spherical valve body. When the electric lunch box is working, the steam lifts the valve body and enters the gas collector. After the heating is completed, the valve body closes the air outlet to prevent condensed water from flowing back.
[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.

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 and the outer side surface of the heating element fixing frame 22 fit together, which plays a role of 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. The lower box body 1 does not have a bottom surface, and the bottom liner 3 can be directly placed on the heating base for heating, and the insulation layer 2 is supported by the base bracket 24.
[0030] See also Figure 1 , six heating bases 10 are fixed on the bottom plate 104 of the heating layer 101. For the convenience of display, the process of accumulating the heating element fixing frame 22, the heating base 10, the base bracket 24, the lower box body 1, the upper box body 4, and the upper cover 7 in sequence is shown from right to left. In actual use, the electric lunch box structure on the far left is adopted. A slide groove 108 is set on the rear inner wall 106 of the heating layer 101, and a slideway is set on the side of the slide groove 108. A horizontal pin is set at the end of the rotating bracket 107. The pin is located in the slideway, so that the rotating bracket 107 can slide up and down in the slide groove 108, and the rotating bracket 107 can rotate around the pin. The gas collecting shell 8 is fixed to the rotating bracket 107 by screws on both sides, and the rotating bracket 107 is rotated downward to connect the gas collecting nozzle 73 on the gas collecting shell 8 with the gas outlet 71 on the upper cover of the electric lunch box.

The cooler 109 is connected to the exhaust pipe 11 on the electric lunch box. The steam generated by heating the electric lunch box is input into the cooler through a conduit and condensed into liquid water and stored in the storage box 110. An activated carbon adsorption box 111 is also connected to the condenser. The activated carbon adsorption box 111 can be located in the middle of the condenser pipe to reduce the steam temperature before adsorption treatment, which has a better effect.
[0032] The front doors of the steam treatment layer 102 and the storage layer 103 adopt a double-door structure, and the heating layer 101 adopts a front-opening door. The bottom of the front-opening door is rotatably connected to the bottom plate of the heating layer, and a transparent window is provided on the front-opening door. The entire cabinet is sealed, and there is no odor inside the cabinet. The heating cabinet can be placed in the office for multiple people to use.
