It should be noted that, when any of the above current pumping characteristics satisfies the condition, it means that the difference between the current pumping characteristic and the first pre-stored pumping characteristic satisfies the first preset condition. And when any one of the current suction characteristics meets the conditions, the power supply device can be triggered to stop supplying power to the atomizing device, so that the atomizing device stops atomizing tobacco tar, and dry burning of the electronic cigarette is avoided. By implementing the embodiment, the problem of preventing the electronic cigarette from being burned dry under the condition that no oil exists in the atomizing device can be effectively solved.

Further, whether the atomizing device is continuously electrically connected with the power supply device or not can be judged by detecting signals. Specifically, when the atomizing device is continuously electrically connected with the power supply device, an electrical connection signal of the atomizing device electrically connected with the power supply device is a normal value (i.e., no state change occurs), and at this time, whether the atomizing device is continuously electrically connected with the power supply device can be determined by monitoring the AD signal.
In addition, in this embodiment, the control of the operating state of the atomizing device is performed by step S303, step S304, and step S305 according to the comparison result of the current suction characteristic and the pre-stored suction characteristic.

Further, the method for preventing the electronic cigarette from being burned in a dry manner further comprises the following steps: after the user completes the puff, the current puff signature is stored in memory to take the current puff signature as the second pre-stored puff signature for the next puff. It should be noted that, after the user finishes sucking, it means that after the user finishes all sucking, and before the electronic cigarette is immediately powered off and not used, the current sucking feature is stored in the storage, so that the current sucking feature is used as the second pre-stored feature for next sucking comparison. Thus, the second pre-stored feature of the embodiments of the present invention is a dynamic value, not a fixed value.
