[0030] refer to Figure 1 , showing a schematic diagram of the structure of the aerosol generating device circuit.

[0031] As an example, the aerosol generating device circuit includes: a power supply circuit 10, a control circuit 20, and a common anode LED lamp driving circuit 30, wherein the first output end of the power supply circuit 10 is connected to the first input end of the control circuit 20, and the first output end of the control circuit 20 is connected to the input end of the common anode LED lamp driving circuit 30; the common anode LED lamp driving circuit 30 includes an LED lamp group, wherein the LED lamp group includes at least one group of LED lamps, wherein the at least one group of LED lamps includes a first color LED lamp, a second color LED lamp and a third color LED lamp, wherein the left ends of the first color LED lamp, the second color LED lamp and the third color LED lamp in the at least one group of LED lamps are respectively connected to the output end of the control circuit 20, and the right ends are connected in parallel to the output end of the control circuit 20.
