In this embodiment, since the heating element L is connected in parallel with the control switch M, if the communication between the battery rod and the atomizer is unsuccessful, the heating element L can be heated only by sending the PWM signal from the battery rod, so that the atomizer operates in the second mode.

The direction identification circuit 10 shown in this embodiment is the same as the direction identification circuit 10 in the battery rod shown in fig. 9, and the description thereof is omitted.

If the direction recognition circuit 10 recognizes that the atomizer is being inserted into the battery rod, the first switching port P0 outputs a low level signal, so that the seventh switch M7 is turned on, and the first connection pin h1 is connected to the output terminal N of the driving circuit; the second switching port P0' outputs a high level signal, such that the tenth switch T10 is turned on, the point B is grounded, and the second connection pin h2 is grounded.

If the direction recognition circuit 10 recognizes that the atomizer is reversely inserted into the battery rod, the first switching port P0 outputs a high level signal, so that the ninth switch M9 is turned on, and the second connection pin h2 is connected to the output terminal N of the driving circuit; the second switching port P0' outputs a low signal, such that the eighth switch T8 is turned on, the point a is grounded, and the first connection pin h1 is grounded.

In this embodiment, the first capacitor C1, the first diode D1, the fifth resistor R5 in the first switching module 21, and the second capacitor C2, the second diode D2, and the sixth resistor R6 in the second 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 second switch T2 is set to be turned on, when the atomizer is inserted into the battery rod, the first resistor R1 of the battery rod and the resistor R of the atomizer divide the voltage of the power supply VDD, and the first detection communication port P1 detects a jump signal, thereby waking up the driving chip MCU of the battery rod. At this time, the first detecting communication port P1 and the second detecting communication port P1' of the driving chip 100 of the battery rod send a string of data to the nebulizer through the first connection pin h1 and the second connection pin h2, respectively, and if the first detecting communication port P1 detects a feedback signal, it indicates that the nebulizer is being inserted into the battery rod; if the second detection communication port P1' detects a feedback signal, it indicates that the nebulizer is inserted into the battery rod reversely.

Specifically, in another embodiment, when it is determined that the resistance value collected by the first detecting communication port P1 is within a first predetermined range and the resistance value collected by the second detecting communication port P1' is within a second predetermined range, it is determined that the nebulizer inserted into the battery rod is positively inserted. Conversely, the insertion is reversed, that is, if the resistance value collected by the first detection communication port P1 is the internal resistance (for example, greater than 3 kilo-ohms) of the driving control circuit 13, and the resistance value collected by the second detection communication port P1' is the resistance value (for example, less than 3 ohms) of the heating element L, it indicates that the atomizer is being inserted into the battery rod; if the resistance value collected by the first detection communication port P1 is the resistance value of the heating element L (e.g., less than 3 ohms), and the resistance value collected by the second detection communication port P1' is the internal resistance value of the driving control circuit 13 (e.g., greater than 3 kilo-ohms), it indicates that the nebulizer is inserted into the battery rod reversely.

This embodiment is described by taking the example where the atomizer is being inserted into the battery rod. Specifically, the first connection pin h1 of the battery lever is connected with the first input end m1 of the atomizer, and the second connection pin h2 of the battery lever is connected with the second input end m2 of the atomizer. In the embodiment, the first switch port P0 controls the first switch T1 to be turned off, and the second switch port P0' controls the second switch T2 to be turned on, so that the point B is connected to the ground voltage. At this time, the battery rod supplies the power voltage VDD to the first input end m1 of the atomizer through the first driving module 31, thereby heating the heating element L.

Fig. 13 is a schematic structural view of the atomizer shown in fig. 3 inserted into the battery rod shown in fig. 9.

Specifically, the first switch T1 is set to be turned on, when the atomizer is inserted into the battery rod, the second resistor R2 of the battery rod and the resistor R of the atomizer divide the power voltage VDD, and the second detection communication port P1' detects a jump signal, thereby waking up the driving chip MCU of the battery rod. At this time, the first detecting communication port P1 and the second detecting communication port P1' of the driving chip 100 of the battery rod send a string of data to the nebulizer through the first connection pin h1 and the second connection pin h2, respectively, and if the first detecting communication port P1 detects a feedback signal, it indicates that the nebulizer is being inserted into the battery rod; if the second detection communication port P1' detects a feedback signal, it indicates that the nebulizer is inserted into the battery rod reversely.

This embodiment is described by taking the example where the atomizer is being inserted into the battery rod. 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. At this time, the battery rod supplies the power voltage VDD to the first input end m1 of the atomizer through the second driving module 32, thereby heating the heating element L.

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 an atomizer according to a fifth embodiment of the present invention. Specifically, in comparison with the nebulizer shown in fig. 3, the chip 1 is also provided with a memory 14, and specifically, the memory 14 is provided in the drive 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.

The memory 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 the memory 14 is valid, it indicates that the nebulizer cannot be used; if the rejection parameter stored in the memory 14 is invalid, it indicates that the nebulizer can be used.

In particular, the communication interface SDA of the chip 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 the memory 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 the memory 14 of the atomizer via the communication interface SDA.

Specifically, when the scrapping parameter is in an effective state, the driving control circuit 13 controls the control switch M to be in an abnormal mode, so that the atomizer cannot be used normally. Specifically, the driving control 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 driving control circuit 13 controls the control switch M to be in a normal mode, so that the atomizer can be normally used. Specifically, the driving control 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, the memory 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 driving control circuit 13 further comprises a timer 15. When the atomizer is normally used, the drive control circuit 13 is controlled at predetermined intervals to control the control switch M to be turned off. Specifically, after the drive 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 the drive control circuit 13, and the predetermined code can control the drive control circuit 13 to control the control switch M to close at predetermined intervals.

In one embodiment, when it is detected that the atomizer stops pumping, the scrapping parameter and the current pumping parameter of the atomizer are updated, and if the updated current pumping parameter reaches the default pumping parameter, the scrapping parameter in the atomizer is updated to be in an effective state.

Specifically, be provided with miaow head or airflow sensor in the battery pole, when miaow head or airflow sensor detected the gas flow through, the battery pole was awaken up from the sleep state, sent and switched on signal to atomizer, and after the atomizer received the turn-on command, switch on through drive control circuit 13 control switch M, and the battery pole acquires default heating parameter and heats heating element L afterwards to make the atomizer normally use. 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 driving control 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.

Specifically, a memory 14 is arranged in the atomizer, the memory 14 stores scrapping parameters, when the atomizer is inserted into the battery rod, the battery rod performs communication authentication with a communication interface SDA of the atomizer by detecting the communication port D, and if the authentication is successful, the battery rod reads the scrapping parameters. Specifically, the battery pole still includes: the identification circuit 50 detects that the communication port D communicates with the nebulizer through the identification circuit 50.

Step S12: determining whether the nebulizer can be used according to the rejection parameter.

Specifically, when the read rejection parameter indicates invalid, it indicates that the nebulizer can be used, and when the read rejection parameter indicates valid, it indicates that the nebulizer cannot be used.

Please refer to fig. 17, the method further includes:

step S21: and acquiring default heating parameters stored in the atomizer, and heating the atomizer according to the default heating parameters.

Specifically, when the read rejection parameter indicates invalid, it indicates that the nebulizer can be used, and the battery lever acquires the default heating parameter stored in the memory 14 of the nebulizer and heats the nebulizer according to the default heating parameter. In one embodiment, the default puff parameter may be, for example, the maximum puff time and the maximum number of puffs after the atomizer is filled with oil. The default heating parameters may be, for example, the corresponding heating power, heating temperature profile, etc.

Specifically, the battery pole still includes: the driving circuit 40, the driving circuit 40 is connected to the driving chip 300 and the identification circuit 50. When the read scrapping parameter indicates invalid, the battery rod acquires a default heating parameter stored in the atomizer, and heats the heating element L of the atomizer by using the driving circuit 40 according to the default heating parameter, so that the atomizer can be normally used.

In an embodiment, the driving chip 300 is the driving chip 100 shown in fig. 9, the detecting communication port D of the driving chip 300 is the first detecting communication port P1 or the second detecting communication port P1 'of the driving chip 100, the identification circuit 50 is the first identification module 11 or the second identification module 12 shown in fig. 9, the driving circuit 40 is the first driving module 31 or the second driving module 32 shown in fig. 9, and the circuit connection manners of the detecting communication port D, the identification circuit 50, the driving circuit 40 and the driving chip 300 are the same as the circuit connection manners of the first detecting communication port P1, the first identification module 11, the first driving module 31 and the driving chip 100 shown in fig. 9 or the circuit connection manners of the second detecting communication port P1', the second identification module 12, the second driving module 32 and the driving chip 100 shown in fig. 9.

It is understood that in other embodiments, the electronic atomization device may also include a battery rod as shown in fig. 9, in which case, before step S11, the method further includes the following steps: and identifying whether the atomizer is inserted positively or negatively and selecting the corresponding detection communication port, the driving module and the identification module.

It is understood that in other embodiments, the electronic atomizer may also include a battery rod as shown in fig. 11, and the specific operation process is similar and will not be described herein.

Step S22: detecting whether the atomizer stops sucking.

Specifically, be provided with miaow head or airflow sensor in the battery pole, when miaow head or airflow sensor detected the circulation of gas, the battery pole was awaken up from the sleep state, send turn-on signal to atomizer, the atomizer received behind the turn-on command, switched on through drive control circuit 13 control switch M, battery pole acquireed default heating parameter and heats heating element L afterwards, thereby make atomizer normal use, when miaow head or airflow sensor detected not to have the circulation of gas, then the atomizer stopped the suction.

Step S23: and when the atomizer stops sucking, updating the current sucking times of the atomizer and the scrapping parameters.

When the microphone or the airflow sensor detects that no airflow passes through, the atomizer stops sucking, the battery rod stops heating the heating element L, and current suction parameters in the atomizer are updated 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.

Further, if the scrapped parameter of the atomizer is updated to the valid state, the driving control 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.

When the battery rod achieves its communication with the atomizer, the atomizer operates in a first mode; the nebulizer operates in the second mode when the battery rod does not achieve its communication with the nebulizer. Specifically, if the battery rod realizes the communication with the atomizer, it can indicate that the battery rod and the atomizer are factory products of the same manufacturer, and if the battery rod does not realize the communication with the atomizer, it can indicate that the battery rod and the atomizer are not factory products of the same manufacturer.
