Two-contact electronic cigarette and authentication method thereof

Abstract

The invention discloses a two-contact electronic cigarette and an authentication method thereof. The two-contact electronic cigarette comprises an electronic cigarette rod and an electronic cigarettecartridge, and two contacts of a first circuit of the electronic cigarette rod and two contacts of a second circuit of the electronic cigarette cartridge are in circuit connection; the two-contact electronic cigarette is used for achieving matching authentication of the electronic cigarette rod and the electronic cigarette cartridge. On the basis of connection of the two contacts, the smoke cartridge receives an authentication command sent by the cigarette rod, encryption calculation is completed; a subcarrier load modulation method is adopted, encryption authentication information is fed backto the cigarette rod, so that information interaction and anti-counterfeiting authentication of the smoke cartridge and the cigarette rod are achieved. Compared with a traditional four-contact or three-contact cigarette cartridge, the two-contact cigarette cartridge has the advantages that the number of contacts is reduced, only one NMOS switch and one load resistor need to be additionally arranged in the internal structure of the two-contact cigarette cartridge, and the production and manufacturing cost of the cigarette cartridge is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to a two-contact electronic cigarette and an authentication method thereof. Background technique [0002] E-cigarettes are composed of two parts: a cigarette stick and a cartridge. The stick includes a battery, integrated control circuit, etc., and the cartridge includes an atomizer, smoke oil, and an authentication chip. The pod can be easily plugged and pulled out on the pod, and the two are electrically connected through contacts. [0003] The product with the largest shipment volume in the electronic cigarette market is the cartridge-changing electronic cigarette, and the most valuable part of the cartridge-changing electronic cigarette is the replaceable cartridge. Replaceable pods are consumables and are the main source of profit for branded e-cigarette manufacturers. According to statistics, the global annual shipment of replaceable pods reaches billions.
