The invention discloses a method for preventing a child from smoking an electronic cigarette accidentally, and the method comprises the steps: S0, waiting for unlocking, and going to step S1 if an unlocking signal is transmitted; S1, enabling the electronic cigarette to work normally; S2, carrying out timing; S3, judging whether a smoking signal is received or not in a first preset time: going to step S4 if the smoking signal is received, or enabling the electronic cigarette to enter into a locked state, and going to step S0 if the smoking signal is not received; S4, enabling the electronic cigarette to carry out atomizing operation, and going to step S2 after the smoking signal at this time is transmitted. When the electronic cigarette is at the locked state, the electronic cigarette cannot make any response even if the child smokes the electronic cigarette accidentally or non-inhaled air flowing triggers a smoking switch or a user starts the smoking switch accidentally.
