In this embodiment, the first capacitor C1, the first diode D1, the fifth resistor R5 in thefirst switching module 21, and the second capacitor C2, the second diode D2, and the sixth resistor R6 in thesecond switching module 22 can ensure that the corresponding seventh switch T7 and the corresponding ninth switch T9 can be turned on quickly when the eleventh switch T11 is turned on, and ensure that the corresponding seventh switch T7 and the corresponding ninth switch T9 can be kept on continuously when the eleventh switch T11 is turned off.

When the atomizer is being inserted into the battery lever and the PWM signal is outputted through the eleventh switch T11 to supply power to the heating element L, the eleventh switch T11 is turned on (corresponding to a high state of the PWM signal) when the first driving port P2 is at a low level, and supplies power to the sources of the seventh switch T7 and the ninth switch T9. At this time, since the eighth switch T8 is turned off, the gate of the seventh switch T7 is clamped to the low level by the first diode D1 and the first switch port P0, thereby turning on the seventh switch T7. The first capacitor C1 is charged to a voltage difference Δ V between the gate and the source of the seventh switch T7, so that the current is inputted to the first input terminal m1 of the atomizer through the seventh switch T7, i.e., the output terminal N of the driving circuit is inputted to the first input terminal m1 of the atomizer. When the first driving port P2 is at a high level, the eleventh switch T11 is turned off (corresponding to a low level state of the PWM signal), and the source of the seventh switch T7 is pulled down to a low voltage by the heating element L, but since the first capacitor C1 only has a discharge channel of the fifth resistor R5, the voltage across the first capacitor C1 is not rapidly powered down, so that the seventh switch T7 can be maintained to be continuously turned on, that is, the output terminal N of the driving circuit is input to the first input terminal m1 of the atomizer, thereby ensuring that the twelfth switch T12 and the seventh resistor R7 can collect parameters of the heating element L.

When the atomizer is reversely inserted into the battery lever and the PWM signal is outputted through the eleventh switch T11 to supply power to the heating element L, when the first driving port P2 is at a low level, the eleventh switch T11 is turned on (corresponding to a high level state of the PWM signal), and power is supplied to the sources of the seventh switch T7 and the ninth switch T9. At this time, since the tenth switch T10 is turned off, the gate of the ninth switch T9 is clamped to be low by the second diode D2 and the second switching port P0', so that the ninth switch T9 is turned on. The second capacitor C2 is charged to the voltage difference Δ V between the gate and the source of the ninth switch T9, so that the current is inputted to the second input terminal m2 of the atomizer through the ninth switch T9, i.e., the output terminal N of the driving circuit is inputted to the second input terminal m2 of the atomizer. When the first driving port P2 is at a high level, the eleventh switch T11 is turned off (corresponding to a low level state of the PWM signal), and the source of the ninth switch T9 is pulled down to a low voltage by the heating element L, but since the second capacitor C2 only has a discharging channel of the sixth resistor R6, the voltage across the second capacitor C2 is not rapidly powered down, so that the ninth switch T9 is maintained to be continuously turned on, that is, the output terminal N of the driving circuit is input to the second input terminal m2 of the atomizer, thereby ensuring that the twelfth switch T12 and the seventh resistor R7 channel can collect parameters of the heating element L.

Specifically, the first connection pin h1 of the battery lever is connected with the second input end m2 of the atomizer, and the second connection pin h2 of the battery lever is connected with the first input end m1 of the atomizer. In the embodiment, the first switch port P0 controls the first switch T1 to be turned on, and the second switch port P0' controls the second switch T2 to be turned off, so that the point a is connected to the ground voltage.

For a specific working principle of the atomizer shown in fig. 3 being inserted into the battery rod shown in fig. 11 in a forward or reverse manner, reference is made to the above description, and details are not repeated.

Fig. 14 is a schematic structural diagram of a fifth embodiment of the atomizer according to the present invention. Specifically, in comparison with the nebulizer shown in fig. 3, thechip 1 is also provided with amemory 14, and specifically, thememory 14 is provided in thedrive control circuit 13. It should be noted that, for the sake of brevity, the technical features shown in fig. 3 are not fully shown in fig. 14, and the technical features not shown can be directly referred to the description of fig. 3.

Thememory 14 stores the discard parameters. The rejection parameter is used to identify whether the nebulizer can be used. Specifically, if the rejection parameter stored in thememory 14 is valid, it indicates that the nebulizer cannot be used; if the rejection parameter stored in thememory 14 is invalid, it indicates that the nebulizer can be used.

In particular, the communication interface SDA of thechip 1 communicates with the battery lever. Specifically, when the nebulizer is inserted into the battery lever, the nebulizer authenticates with the battery lever through the communication interface SDA. If the authentication is successful, the battery stem reads the rejection parameters stored in thememory 14 to determine whether the nebulizer can be used.

Specifically, when the nebulizer is inserted into the battery rod, the battery rod sends data to the communication interface SDA of the nebulizer, and if feedback data from the nebulizer is received, the authentication is successful. At this point the battery lever reads the rejection parameter stored in thememory 14 of the atomizer via the communication interface SDA.

Specifically, when the scrapping parameter is in an effective state, the drivingcontrol circuit 13 controls the control switch M to be in an abnormal mode, so that the atomizer cannot be used normally. Specifically, the drivingcontrol circuit 13 controls the control switch M to be turned off, and at this time, the battery rod cannot heat the heating element L, and the atomizer cannot be used normally.

When the scrapping parameter is in an invalid state, the drivingcontrol circuit 13 controls the control switch M to be in a normal mode, so that the atomizer can be normally used. Specifically, the drivingcontrol circuit 13 controls the control switch M to be turned on, and at this time, the battery rod heats the heating element L, so that the atomizer is normally used.

Specifically, in an embodiment, thememory 14 includes a data protection area and a data readable and writable area, and the data readable and writable area stores the current pumping parameter and the scrapping parameter; the data protection area stores default pumping parameters and default heating parameters. The default suction parameters may be, for example, the longest suction time and the maximum suction times after the atomizer is filled with oil. The default heating parameters may be, for example, the corresponding heating power, heating temperature profile, etc. The current puff parameter may be, for example, the current puff time or the current puff count of the nebulizer.

The nebulizer can be used when the rejection parameter is in an invalid state. The default heating parameters are obtained by the battery lever, which heats the heating element L according to the default heating parameters, so that the atomizer is normally used. Specifically, when the battery rod heats the heating element L, the driving chip can control and output the corresponding heating power to enable the heating element L to reach the predetermined temperature curve, so as to prevent overheating of the atomized matrix.

In an embodiment, the drivingcontrol circuit 13 further comprises atimer 15. When the atomizer is normally used, thedrive control circuit 13 is controlled at predetermined intervals to control the control switch M to be turned off. Specifically, after thedrive control circuit 13 controls the control switch M to be turned on, the control switch M is controlled to be turned off at every timer timing. Or in another embodiment, a predetermined code is written in thedrive control circuit 13, and the predetermined code can control thedrive control circuit 13 to control the control switch M to close at predetermined intervals.

Therefore, different atomizing matrixes can be atomized by adopting different heating parameters, and the user experience is improved. When the microphone or the airflow sensor detects that the airflow stops, that is, the suction stops, the battery rod stops heating the heating element L, and updates the current suction parameters in the atomizer according to the suction time or the suction times of the suction process. For example, when it is detected that the user stops pumping the electronic atomizer, the battery rod accumulates the pumped time or number with the pumped time or number in the current pumping parameter, and updates the current pumping parameter with the accumulated result.

Optionally, after the current suction parameter is updated, the updated current suction parameter is compared with the default suction time, and when the updated current suction parameter reaches the default suction parameter, it indicates that the suction time or the suction frequency of the atomizer has been used up, and at this time, the scrapped parameter in the atomizer is updated to an effective state to lock the atomizer and prevent the atomizer from being used. And when the updated current suction parameter does not reach the default suction parameter, the suction time or the suction times of the atomizer are not used up, the battery rod enters the sleep time, and when the next air flow is detected, the atomizer is continuously powered to heat the heating element L.

Further, if the scrapped parameter of the atomizer is updated to be valid, the drivingcontrol circuit 13 controls the control switch M to be always in the off state, so that the atomizer which is filled with oil by the user can be prohibited from being used.
