[0080] In this embodiment, the food warming device 100 further includes a circuit board 200, which is disposed between the housing 170 and the bottom plate 120 and is electrically connected to the furnace body 180. The food warming device 100 can be electrically controlled by the circuit board 200, thereby improving the accuracy and controllability of the food warming device 100 during operation. Meanwhile, the circuit board 200 is disposed between the housing 170 and the bottom plate 120 and is electrically connected to the furnace body 180, thereby improving the control effect of the furnace body 180, and also preventing the circuit board 200 from being damaged by the outside world, thereby extending the service life of the circuit board 200.

[0081] This embodiment provides a food warming device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0082] like Figure 1 , Figure 2 and Figure 3 As shown, the air outlet end of the fan 140 faces the circuit board 200 ; and / or the air outlet end of the fan 140 faces the radial outer side of the furnace body 180 .

[0083] In this embodiment, the air outlet of the fan 140 faces the circuit board 200, and / or the air outlet of the fan 140 faces the radial outer side of the furnace body 180. The airflow blown out by the air outlet of the fan 140 can take away the heat of the circuit board 200 and the furnace body 180, thereby improving the heat dissipation efficiency, and also preventing the circuit board 200 from overheating, thereby reducing the probability of the circuit board 200 failing due to overheating.

[0084] This embodiment provides a food warming device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

While ensuring the normal operation of the fan 140 in the food warming device 100, the height is reduced to facilitate production and installation, and the center of gravity of the food warming device 100 is lowered. When the food warming device 100 is placed on a desktop, the stability can be improved, shaking can be avoided, and practicality can be improved.

[0090] Specifically, the distance between the first surface 196 and the second surface 114 is L, and the distance L between the first surface 196 and the second surface 114 is greater than or equal to 45 mm and less than or equal to 55 mm.

[0091] Specifically, the distance L between the first surface 196 and the second surface 114 may be 45 mm, the distance L between the first surface 196 and the second surface 114 may be 47 mm, the distance L between the first surface 196 and the second surface 114 may be 50 mm, the distance L between the first surface 196 and the second surface 114 may be 53 mm, and the distance L between the first surface 196 and the second surface 114 may be 55 mm.
