In the embodiment of the present invention, in order to achieve mutual recognition of the battery lever 11 and the atomizer, the atomizer inserted into the battery lever 11 includes an identification circuit. Specifically, when the atomizer inserted into the battery rod 11 includes the identification circuit, the first control chip 111 controls the first switch M1 to supply power to the atomizer by the first driving signal; and controls the second switch M2 with the second driving signal to communicate with the identification circuit of the nebulizer to obtain identification information of the nebulizer and adjusts the first driving signal to drive the nebulizer with a corresponding power according to the fed-back identification information.

And when the second driving signal is at the high level signal of 300us, the identification circuit of the atomizer performs a discharging operation on the power supply voltage connection terminal n1 of the battery lever 11 to generate the high level signal of 300us or the high level signal of 150us at the power supply voltage connection terminal n1 of the battery lever 11 as a corresponding feedback digital signal, constituting the fed back identification information to be fed back to the feedback terminal ADC of the first control chip 111. Wherein, the high level signal of 150us is the feedback voltage of the seventh duration. Specifically, in an embodiment, if the feedback voltage received by the feedback terminal ADC of the first control chip 111 is a high level signal of 300us, it indicates that the nebulizer return data "1" is received, and if the feedback voltage received by the feedback terminal ADC of the first control chip 111 is a high level signal of 150us, it indicates that the nebulizer return data "0" is received. It can be understood that, as shown in fig. 3, the feedback voltage of the high level signal received by the feedback terminal ADC of the first control chip 111 is the resistance value of the heating element H and the divided voltage value of the first resistor R1, and the voltage value is lower than the high level signal output by the first driving signal and the second driving signal.

Specifically, in the data transmission period L2, the battery lever 11 turns on the first switch M1 to charge the storage capacitor C1 every cycle, then turns on the first switch M2, and transmits transmission voltages with different pulse widths of 300us and 150us to the analog-to-digital conversion terminal of the second control chip 121 of the nebulizer 12 through the second switch M2 to collect and identify the transmission voltages, when the transmission voltage duration collected by the analog-to-digital conversion terminal of the second control chip 121 of the nebulizer 12 is 300us, it indicates that the nebulizer 12 receives data "1", and when the transmission voltage duration collected by the analog-to-digital conversion terminal of the second control chip 121 of the nebulizer 12 is 150us, it indicates that the nebulizer 12 receives data "0". In a specific embodiment, in consideration of cost, in practical application, the atomizer of the first embodiment shown in fig. 4 is preferably used, which has lower cost compared with the atomizer of the second embodiment shown in fig. 5.

When the battery lever 11 operates in the waiting response period L3, the second control chip 121 controls the switch module Q3 to perform a discharging operation on the power supply voltage connection terminal m1 of the atomizer 12, so that the waiting voltage of the thirteenth duration on the power supply voltage connection terminal m1 of the atomizer 12 is switched to the response voltage of the fifteenth duration, thereby generating a response signal on the power supply voltage connection terminal m1 of the atomizer 12 to notify the first control chip 111 that it is waiting to receive the fed back identification information.

If the atomizer 12 receives the transmission data and returns the corresponding voltage, the driving terminal P3 of the second control chip 121 of the atomizer 12 outputs a high level signal of 150us, so that the level of the power supply voltage connection terminal m1 of the atomizer 12 is switched from the high level signal of 300us to the high level signal of 150 us. At this time, the feedback section ADC of the first control chip 111 of the battery lever 11 collects the response voltage of the power supply voltage connection terminal m1 of the nebulizer 12, and if the duration of the response voltage is not 300us, but 150us, it indicates that the nebulizer has responded. When the battery lever 11 is operated for the feedback data receiving period L4, the second control chip 121 controls the switch module Q3 to determine the discharging operation to the power supply voltage connection terminal m1 of the atomizer 12, so that the power supply voltage connection terminal m1 of the atomizer 12 generates the feedback voltage of the fifth duration or the feedback voltage of the seventh duration as the corresponding feedback digital signal to constitute the identification information being fed back. Specifically, when the battery lever 11 is operated in the feedback data receiving period L4, the second driving end P2 of the first control chip 111 of the battery lever 11 applies a high level signal of 300us to the second switch M2, and if the driving end P3 of the second control chip 121 of the atomizer 12 outputs a low level signal, that is, the switch module Q3 is turned off or outputs data "1", at this time, the voltage of the power supply voltage connection end M1 of the atomizer 12 continues to be the high level signal of 300 us; if the driving terminal P3 of the second control chip 121 of the atomizer 12 outputs a high level signal, that is, the switch module Q3 is turned on or outputs data "0", at this time, the voltage of the power voltage connection terminal m1 of the atomizer 12 is continuously a high level signal of 150 us. At this time, when the feedback terminal ADC of the first control chip 111 of the battery lever 11 acquires a high level signal that the voltage at the power supply voltage connection terminal m1 of the nebulizer 12 continues to be 300us, it indicates that "1" of the data returned by the nebulizer 12 is received, and when the feedback terminal ADC of the first control chip 111 of the battery lever 11 acquires a high level signal that the voltage at the power supply voltage connection terminal m1 of the nebulizer 12 continues to be 150us, it indicates that "0" of the data returned by the nebulizer 12 is received.

Specifically, when the battery lever 11 is operated in the transmission data period L2, if the atomizer 12 is being inserted into the battery lever 11, that is, the power supply voltage connection terminal M1 of the atomizer 12 is connected to the power supply voltage connection terminal n1 of the battery lever 11, and the ground voltage connection terminal M2 of the atomizer 12 is connected to the ground voltage connection terminal n2 of the battery lever, the control terminal (gate) voltages of the third switch M3 and the fourth switch M4 are at a low level, and at this time, both the third switch M3 and the fourth switch M4 are turned off, and the voltage first reaches the first terminal (source) of the fourth switch M4, because the fourth switch M4 has a body diode, the voltage may reach the cathode from the anode of the body diode, and reach the third switch M3, but because the body diode of the third switch M3 is opposite to the body diode of the fourth switch M4, the third switch M3 may not be passed, thereby achieving the turning off of the switch module 124. If the atomizer 12 is inserted into the battery rod 11 in the reverse direction, that is, the power supply voltage connection end M1 of the atomizer 12 is connected to the ground voltage connection end n2 of the battery rod 11, and the ground voltage connection end M2 of the atomizer 12 is connected to the power supply voltage connection end n1 of the battery rod 11, the voltages at the control ends (gates) of the third switch M3 and the fourth switch M4 are at a low level, and at this time, the third switch M3 and the fourth switch M4 are both turned off, and the voltage first reaches the first on end (source) of the third switch M3, because the third switch M3 has a body diode, the voltage can reach the cathode from the anode of the body diode and reach the fourth switch M4, but because the body diode of the third switch M3 is opposite to the body diode of the fourth switch M4, the switch M4 cannot pass through, and the switch module 124 is turned off.

If only the fourth switch M4 is present in the switch module 124, the fourth switch M4 may be normally turned off or on when the atomizer 12 is being inserted into the battery rod 11, but the body diode of the fourth switch M4 will conduct the supply voltage connection M1 of the atomizer 12 directly to ground when the atomizer is being inserted backwards into the battery rod 11.
