Referring to fig. 1, in an embodiment, a heating device 100 includes a liner, a coil 112 and a fan 113, the liner can be used to contain food materials and has a certain heat preservation characteristic to keep the food materials delicious, and the coil 112 is used to heat the liner and has a certain interval with the liner. At least part of the bottom wall of the inner container can be made of magnetic conductive material, and the magnetic field of the magnetic conductive material on the coil 112 can realize electromagnetic induction heating, so that the whole inner container is uniformly heated. Specifically, when the magnetic conductive material of the inner container is heated under the action of the magnetic field generated by the coil 112, the inner container generates a sinking pressure, and due to the space between the inner container and the coil 112, the coil 112 does not bear the pressure of the inner container, that is, the coil 112 may not be deformed slightly due to no stress, and thus the structure of the coil 112 is not affected.

In an embodiment, the fan 113 is connected to the coil 112 and located at the heat dissipation channel, when the coil 112 inductively heats the inner container, the coil 112 generates heat, and the temperature in the accommodating cavity 213 rises, at this time, the fan 113 is started, so that the external air forms an air flow and is drawn into the accommodating cavity 213, and the air flow can draw the heat to the outside through the heat dissipation channel, so that the internal air and the external air are replaced with each other, and the heating device 10 achieves a heat dissipation effect.

Referring to fig. 3, in an embodiment, the bottom housing 200 includes a housing 210, the housing 210 has a bottom wall 211 and a side wall 212, the side wall 212 is extended from an edge of the bottom wall 211, the side wall 212 and the bottom wall 211 form a receiving cavity 213, and the heating device 100 is received in the receiving cavity 213. In one embodiment, the bottom wall 211 defines an inlet 215 and a first outlet 216, and the inlet 215 and the first outlet 216 are respectively connected to the receiving cavity 213. The bottom housing 200 further includes a fan cover, which is disposed at the air inlet 215, is substantially in a grid shape, and includes a plurality of air holes 2151, so that air can be drawn in from the plurality of air holes 2151.

The boss 214 is located between the air inlet 215 and the first air outlet 216, and the blower 113 is activated to draw outside air into the receiving cavity 213 and passes through the boss 214 to discharge air flow from the first air outlet 216. So that the external air is continuously pumped into the accommodating cavity 213, the internal air is continuously exhausted to the outside, and the internal air and the external air are replaced. Specifically, because the boss 214 protrudes from the bottom wall 211, that is, the boss 214 is closer to the coil 112, and the bottom wall 211 is further from the coil 112, when air is drawn into the accommodating cavity 213, the air flow formed by the air can accelerate the flow of the air flow in the process of passing through the boss 214, and the heat generated by the coil 112 is taken away in time, so that the heat can be discharged to the outside more rapidly.

In an embodiment, the bottom case 200 includes a wind deflector 220, the wind deflector 220 may be made of plastic, metal or synthetic gold, etc., the wind deflector 220 is connected to the boss 214 and is received in the receiving cavity 213, so that the wind deflector 220 and the boss 214 form a groove 221, and the groove 221 may be used for receiving the coil 112 in the heating apparatus 100. The arrangement of the groove 221 can enable the air to be gathered together in the accommodating cavity 213, so as to guide the internal air flow in time and prevent the air flow formed by the air from entering the accommodating cavity 213 and diffusing all around. The heat generated by the coil 112 can be intensively taken away by the air in the circulating process, so that the effects of high efficiency and timely heat dissipation can be achieved. It will be appreciated that the size of the bosses 214 can be adapted to the size of the coil 112 so that the heat generated by the coil 112 can be carried away as much as possible to accelerate the air circulation when the air circulates in the grooves 221. Further, the number of the air deflectors 220 is at least two, and the two air deflectors 220 are spaced on the bottom wall 211 and form a groove 221 with the bottom wall 211.
