Electronic cigarette and method for identifying whether there is a match between a battery component and an atomizer component therein

An electronic cigarette, comprising a battery assembly and an atomizer assembly jointed with the battery assembly;

• wherein the electronic cigarette further comprises a laser identifying assembly, the laser identifying assembly includes an information portion, a laser transceiver and a controlling module, the information portion includes a group of grooves and bulges which represent a product information, the information portion is defined on a surface of one of the battery assembly and the atomizer assembly, the laser transceiver is mounted at a corresponding position on a side of the other of the battery assembly and the atomizer assembly which faces the information portion;
• when the atomizer assembly is jointed with the battery assembly, the laser transceiver aims at the information portion, and the information portion reflects an original laser beam sent out by the laser transceiver back to the laser transceiver, then the controlling module determines whether the atomizer assembly is matched with the battery assembly according to the reflected laser beam received by the laser transceiver.
