[0002] Compared with traditional cigarettes, new electronic cigarettes are less harmful to the human body, safer and more environmentally friendly to use. The number of smokers who replace traditional cigarettes with electronic cigarettes is increasing year by year. Electronic cigarettes on the market usually consist of two parts: an atomizer component with replaceable oil and a reusable control circuit component. However, while the atomizer component with replaceable oil can provide customers with a differentiated experience, it also provides an opportunity for unscrupulous manufacturers. They use inferior oil to imitate the atomizer components of brand electronic cigarette manufacturers and impact the market at a low price, which not only harms the health of consumers, but also brings unsafe factors to the product, and is not conducive to the maintenance of the brand manufacturer's product. Therefore, it is necessary to upgrade the hardware and add an encryption identification chip to authenticate the atomizer assembly connected to the electronic cigarette and reject the use request of non-original atomizers. However, the existing electronic cigarette control circuit assembly and the atomizer assembly have only two PIN pins connected. Both power supply and communication are required by relying on the two PIN pins. Therefore, it is necessary to distinguish the positive and negative poles of the interface of the atomizer assembly when the atomizer assembly is connected to the control circuit assembly to avoid normal power supply and communication when reverse connection occurs, which makes it impossible for the electronic cigarette to be authenticated and used normally.
