The control circuit 4 realizes the adjustment and control of the working state of the electric flame stove through the control of the driving circuit 5. The driving circuit 5 adjusts the on and off of the voltage transformation circuit 6 under the control of the control circuit 4, thereby controlling the output power of the voltage transformation circuit 6. When the drive circuit 5 is turned on, the low voltage electrical signal passes through the primary winding of the transformer, causing the secondary winding to induce a change in the electromagnetic field, thereby raising the voltage to a high voltage.

The heat generated by the transformer circuit 6 and the driving circuit 5 can be smoothly dissipated by the air flow produced by the first and second heat dissipation fans 141 and 151. Meanwhile, in order to ensure the normal operation and the heat dissipation effect of the rectifying circuit 8, the rectifying circuit 8 is provided with the heat dissipation fins 81, the heat insulation plate 11 is provided with the air guide notch 111 for dissipating heat of the heat dissipation fins 81, air flow of the first cavity 12 flows from the air guide notch 111 to the second cavity 13 after being extruded, heat of the heat dissipation fins 81 is smoothly dissipated, and finally hot air is discharged from the air outlet grille 16 on the outer side wall of the second cavity 13, so that a good heat dissipation effect is achieved.
