Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] It should be understood that, and also noted, in the embodiments, the functions / actions may appear in a different order than those shown in the figures.

[0028] like Figure 1 As shown in the figure, an electronic cigarette based on resistance identification of different flavor cartridges in this embodiment includes a main unit and a cartridge unit. The main unit and the cartridge unit can be separated, and can also be assembled and used by connecting three pins of the main unit with three conductive pins of the cartridge unit.

[0029] The main unit includes a lithium battery, an ADC voltage detection circuit, a microcontroller, an auxiliary resistor, a spring pin, a display screen, a charging circuit, and a heating wire drive circuit.

[0030] The ADC voltage detection circuit connects to the identification resistor in the cartridge section and outputs a detection voltage. The microcontroller identifies different flavor cartridges based on the detection voltage from the ADC circuit and outputs corresponding matching parameters. The display screen shows the battery percentage, displays different error alarms, and shows the serial number of the identified cartridge. The contact pins connect to the cartridge section; two of the three contact pins transmit the power required by the heating wire, and the third pin receives the voltage identified by the cartridge.
