Specifically, in the data transmission period L2, the first switch M1 is turned on to charge the storage capacitor C1 every cycle of the battery rod 11, then the first switch M2 is turned on, the sending voltages with different pulse widths of 300us and 150us are sent to the analog-to-digital conversion end of the second control chip 121 of the atomizer 12 through the second switch M2 to be collected and identified, when the duration of the sending voltage collected by the analog-to-digital conversion end of the second control chip 121 of the atomizer 12 is 300us, it is indicated that the atomizer 12 receives the data "1", and when the duration of the sending voltage collected by the analog-to-digital conversion end of the second control chip 121 of the atomizer 12 is 150us, it is indicated that the atomizer 12 receives the data "0". In one embodiment, considering cost, in practical applications, the atomizer of the first embodiment shown in fig. 4 is preferred, which has lower cost than 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 switching module Q3 to perform a discharging operation on the power supply voltage connection terminal m1 of the atomizer 12 such 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 at the power supply voltage connection terminal m1 of the atomizer 12 to inform the first control chip 111 to wait for receiving the fed-back identification information. Specifically, when the battery lever 11 is operated in the waiting response period L3, the second driving signal output by the second driving end P2 of the first control chip 111 of the battery lever 11 is a high level signal of 300us, and if the nebulizer 12 is still processing data, the driving end P3 of the second control chip 121 of the nebulizer 12 does not output any signal, i.e. is in a low level state, and at this time, the level of the power supply voltage connection terminal m1 of the nebulizer 12 is continuously a high level signal of 300 us. If the nebulizer 12 receives the transmission data and returns the corresponding voltage, the driving terminal P3 of the second control chip 121 of the nebulizer 12 outputs a high level signal of 150us, so that the level of the power voltage connection terminal m1 of the nebulizer 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 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 pole 11 is operated in the feedback data receiving period L4, the second control chip 121 controls the switch module Q3 to determine the discharging operation on the power voltage connection terminal m1 of the atomizer 12, so that the power 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 form the fed-back identification information. Specifically, when the battery pole 11 is operated in the feedback data receiving period L4, the second driving end P2 of the first control chip 111 of the battery pole 11 applies a high level signal of 300us to the second switch M2, 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 voltage connection end M1 of the atomizer 12 is continuously 300us of the high level signal; if the driving end P3 of the second control chip 121 of the atomizer 12 outputs a high level signal, i.e. the switch module Q3 is turned on or outputs data "0", the voltage at the power voltage connection terminal m1 of the atomizer 12 is continuously 150 us. At this time, if the feedback terminal ADC of the first control chip 111 of the battery lever 11 collects a high level signal that the voltage of the power voltage connection terminal m1 of the nebulizer 12 is continuously 300us, it indicates that the data "1" returned from the nebulizer 12 is received, and if the feedback terminal ADC of the first control chip 111 of the battery lever 11 collects a high level signal that the voltage of the power voltage connection terminal m1 of the nebulizer 12 is continuously 150us, it indicates that the data "0" returned from the nebulizer 12 is received.

In this embodiment, the switch module 124, i.e., the switch module Q3 in fig. 4 and 5, includes a third switch M3 and a fourth switch M4, wherein the third switch M3 includes a first path end, a second path end and a control end, and the fourth switch M4 includes a first path end, a second path end and a control end. Specifically, the control ends of the third switch M3 and the fourth switch M4 are connected together as the control end of the switch module 124, and are connected to the driving end P3 of the second control chip 121. The second path end of the third switch M3 and the second path end of the fourth switch M4 are connected together, and the first path end of the third switch M3 and the first path end of the fourth switch M4 serve as the first path end and the second path end of the switch module 124, respectively, and are connected to the first input end and the second input end of the atomizer, respectively. Further, the first path end of the third switch M3 is connected to the ground voltage connection end M2 of the atomizer 12, and the first path end of the fourth switch M4 is connected to the power voltage connection end M1 of the atomizer 12.

In one embodiment, the third switch M3 and the fourth switch M4 are NMOSFETs. In this embodiment, the drains of the third switch M3 and the fourth switch M4 are connected to each other to realize on/off of the circuit. Which can prevent the voltage from being clamped to ground voltage by the body diodes of the third switch M3 and the fourth switch M4 when the atomizer 12 is inserted in the battery pole 11 in the forward or reverse direction.

Specifically, when the battery pole 11 is operating in the data transmission period L2, if the nebulizer 12 is being inserted into the battery pole 11, that is, the power voltage connection terminal M1 of the nebulizer 12 is connected to the power voltage connection terminal n1 of the battery pole 11, and the ground voltage connection terminal M2 of the nebulizer 12 is connected to the ground voltage connection terminal n2 of the battery pole, the voltages at the control terminals (gates) of the third switch M3 and the fourth switch M4 are at the low level, at this time, the third switch M3 and the fourth switch M4 are turned off, and the voltage reaches the first path terminal (source) of the fourth switch M4 first, because the fourth switch M4 has a body diode, the voltage can reach the cathode from the anode of the body diode, and reach the third switch M3, but the body diode of the third switch M3 and the body diode of the fourth switch M4 cannot pass through the third switch M3, so that the switch module 124 cannot be turned off. If the atomizer 12 is reversely inserted into the battery pole 11, that is, the power voltage connection terminal M1 of the atomizer 12 is connected to the ground voltage connection terminal n2 of the battery pole 11, and the ground voltage connection terminal M2 of the atomizer 12 is connected to the power voltage connection terminal n1 of the battery pole 11, the voltages at the control terminals (gates) of the third switch M3 and the fourth switch M4 are at low level, at this time, both the third switch M3 and the fourth switch M4 are turned off, and the voltage reaches the first pass terminal (source) of the third switch M3 first, because the third switch M3 has a body diode, the voltage can reach the cathode from the anode of the body diode to the fourth switch M4, but the direction of the body diode of the third switch M3 is opposite to that of the fourth switch M4, so that the switch module 124 cannot be turned off.

The voltage at the first pass (source) end of the fourth switch M4 is clamped to Vsd by the body diode, and when the voltage difference Vgs between the gate and the source of the fourth switch M4 is greater than the threshold voltage, the fourth switch M4 is turned on, so as to turn on the switch module 124. If the atomizer 12 is reversely inserted into the battery pole 11, that is, the power voltage connection terminal M1 of the atomizer 12 is connected to the ground voltage connection terminal n2 of the battery pole 11, and the ground voltage connection terminal M2 of the atomizer 12 is connected to the power voltage connection terminal n1 of the battery pole 11, the voltages of the control terminals (gates) of the third switch M3 and the fourth switch M4 are at high level, the voltage difference Vgs between the control terminal (gate) and the first path terminal (source) of the fourth switch M4 is greater than the threshold voltage, at this time, the fourth switch M4 is turned on first, the drain of the third switch M3 is turned on, and then is connected to the ground voltage output terminal GND. The voltage at the first pass end (source) of the third switch M3 is clamped to Vsd by the body diode, and when the voltage difference Vgs between the gate and the source of the third switch M3 is greater than the threshold voltage, the third switch M3 is turned on, so as to further realize the conduction of the switch module 124.

Specifically, if only the third switch M3 is present in the switch module 124, the third switch M3 may be normally turned off or turned on when the nebulizer 12 is being inserted into the battery pole 11, but when the nebulizer is being reversely inserted into the battery pole 11, the body diode of the third switch M3 will directly conduct the ground voltage connection terminal M2 of the nebulizer 12 to the ground. If only the fourth switch M4 exists in the switch module 124, the fourth switch M4 may be normally turned off or turned on when the nebulizer 12 is being inserted into the battery pole 11, but the body diode of the fourth switch M4 may directly turn on the power voltage connection terminal M1 of the nebulizer 12 to the ground when the nebulizer is reversely inserted into the battery pole 11.
