The invention relates to the field of electronic cigarettes, in particular to an electronic cigarette cartridge anti-counterfeiting chip circuit and a power supply method thereof. The electronic cigarette cartridge anti-counterfeiting chip circuit comprises a battery, a main control chip connected to the battery in parallel, an anti-counterfeiting chip connected to the main control chip in parallel, a change-over switch connected to the main control chip in series and a heating wire connected to the anti-counterfeiting chip in parallel, wherein the main control chip is provided with a GPIO interface and controls the on-off of the change-over switch based on a GPIO signal output by the GPIO interface, so that the switching between a heating state and a non-working state of the heating wire is controlled, and meanwhile, an anti-counterfeiting security authentication channel is provided between the anti-counterfeiting chip and the main control chip; and the anti-counterfeiting chip is provided with a first contact and a second contact, the first contact is connected to the GPIO interface and used for data transmission and power supply acquisition, and the second contact is grounded. The main control chip in the electronic cigarette cartridge anti-counterfeiting chip circuit is switched and controlled to be connected with the anti-counterfeiting chip and the heating wire through the change-over switch, the main control chip controls the change-over switch to be connected through using the GPIO signal so as to achieve heating of the heating wire, and meanwhile the anti-counterfeiting safety certification channel is provided between the anti-counterfeiting chip and the main control chip.
Description
technical field [0001] The invention relates to the field of electronic cigarettes, in particular to an anti-counterfeit chip circuit of an electronic cigarette cartridge and a power supply method thereof. Background technique [0002] At present, with the rapid development of the electronic cigarette market, the anti-counterfeiting requirements of electronic cigarette cartridges are becoming more and more important, and because of the particularity of the cartridge products, it is not possible to add cartridge contacts due to the particularity of the cartridge products, so the existing It is difficult to design the circuit structure of the anti-counterfeiting chip of the pod, and it cannot take into account the data transmission and the power supply of the chip. Contents of the invention [0003] Embodiments of the present invention provide an electronic cigarette pod anti-counterfeit chip circuit and a power supply method thereof, to at least solve the technical problem ...
