The smoking trigger signal generated by the smoking trigger unit is a current signal generated by the airflow sensor flowing through the sensing airflow. When a smoking action occurs, the airflow sensor generates a corresponding smoking trigger signal and sends it to the micro processing unit 210 in the control module 200. When receiving the smoking trigger signal, the processing unit 210 proceeds to step S01 to start the identification of the atomizer. In this embodiment, after the identification of the atomizer is completed in step S3, the process proceeds to step S10, and the next smoking action is triggered to trigger the identification of the atomizer in the next round.

Referring to Figure 9, there is shown a flow chart of a third embodiment of the method of identifying an atomizer of the present invention.

The third embodiment differs from the second embodiment in that the second embodiment performs the identification of the atomizer for each smoking action, and the third embodiment performs the fogging after the preset number of smoking actions occur. The identification of the chemist, and in the third embodiment, the recognition action is not performed after the identification of the atomizer is completed.

Specifically, the following triggering step S10 and counting step S20 are further added before step S0 proceeds to step S01:

In the third embodiment, the problem of nebulizer matching is not considered for the smoking action that does not reach the preset number of times, and the user experience is very convenient when the product is displayed.

In summary, the present invention adds a signal generating module to the atomizer to transmit the identification signal to the control module in the battery rod through a wired or wireless connection transmission mode, and the control module determines whether the identification signal or the identification signal is received according to whether the signal is received or not. Correctly determine whether the atomizer and the battery rod match, and then control whether the electrical connection between the battery and the atomization module is turned on. Thus, the electronic cigarette of the present invention can identify the atomizer, and only the battery holder can supply power to the atomizer only if the correct atomizer is recognized. For the mismatched atomizer, the battery rod is mechanically atomized and atomized. The device is connected, but the control module inside the battery rod controls the connection of the battery and the power supply path of the atomization module to be disconnected, and there is no difference in the driving power of the atomizer, which causes the smell of smoke or the amount of smoke is small, or the heating wire is blocked. The difference in value results in overcurrent protection without smoke generation, and the invention can control the alarm unit alarm when the battery rod and the atomizer are mismatched to remind the user to find the problem in time.

The identification method provided by the invention not only provides a simple atomizer identification method after the atomizer is electrically connected with the battery rod, but also provides a method for performing atomizer identification for each smoking action, thereby avoiding In the middle of the replacement of the battery rod, there may be a problem of identification omission, ensuring the rigorous and reliable identification, and the present invention also provides that the atomizer is recognized only when the number of smoking actions reaches a preset number of times, so that the user can be given a certain experience first. It is quite convenient when displaying products.
