DETAILED DESCRIPTION

[0026] The specific implementation modes of the present invention are described below in conjunction with the accompanying drawings and embodiments. However, the following embodiments are only used to illustrate the present invention in detail and do not limit the scope of the present invention in any way.

[0027] Embodiment 1: An electric lunch box, see Figures 1 to 5 , including a box body, a heating base 10, and an upper cover 7. 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 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.

[0029] 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.

[0030] 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 pipe 71, which is vertically arranged. The air outlet pipe 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 horizontally tubular, bent at the right end, and provided with an air collecting channel inside. The exhaust pipe 11 is connected to the left end of the gas collecting shell 8 and communicated with the gas collecting channel. A gas collecting nozzle 73 connected to the air outlet pipe 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 air outlet pipe 71. The gas collecting nozzle 73 is spherical and is clamped with the groove at the top of the air outlet pipe 71, or the air outlet pipe 71 and the gas collecting nozzle 73 can also be fixedly connected by a thread. A check valve 72 is provided inside the air outlet pipe 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 pipe to prevent condensed water from flowing back.

[0031] The bottom of the electric lunch box is exposed and can be heated directly on the heating plate. The exterior is wrapped with heat-resistant materials to ensure absolute insulation and safety. The convex air outlet on the top can ensure exhaust while preventing the backflow of water droplets formed by water vapor, thereby ensuring the humidity of the rice. The electric lunch box adopts a double-layer design with a steamer in the middle. The upper layer can heat pre-prepared dishes and the lower layer can steam rice. When the electric lunch box is heated, the steam generated will rise to the top of the cooker and then be discharged through the upper exhaust pipe. The discharged steam will be transferred to a cooling mechanism through the exhaust pipe 11, which can be a spirally stacked copper tube or a finned heat pipe. The condensed water will flow into the storage box through a plastic tube for collection and treatment.

[0032] The utility model is described in detail above with reference to the accompanying drawings and embodiments. However, those skilled in the art will appreciate that, without departing from the spirit of the utility model, the specific parameters in the above embodiments may be changed to form a plurality of specific embodiments, which are all within the common variation range of the utility model and will not be described in detail here.
