Compared with the first embodiment shown in fig. 1 described above, the difference is that the chip 1 shown in this embodiment further includes: and the expansion interface NC is used as a reserved interface of the chip 1. Optionally, the extension interface NC is electrically connected with the ground interface GND in the package.
The chip 1 shown in fig. 2 is packaged by the SOT23-6, and the chip 1 shown in fig. 1 is packaged by the SOT23-5, which can reduce the cost maximally in the packaging angle. And the packaging mode of SOT23-6 shown in FIG. 2 is more beneficial to the internal wiring of the chip 1. In the chip 1 shown in fig. 1 and 2, the first path end, the second path end and the control end (corresponding to the drain, the source and the gate respectively) of the control switch M are independently led out, and in practical application, the problem of insufficient current can be solved by introducing an additional switch in parallel with the control switch M, and the problem of reverse conduction of the control switch M can be prevented by introducing an additional switch in series with the control switch M.
Fig. 3 is a schematic structural diagram of a first embodiment of the atomizer of the present invention. Wherein the atomizer comprises a heating element L and a chip 1. The chip 1 is connected to the heating element L, wherein the chip 1 is the chip 1 shown in any one of the embodiments of fig. 1 and 2.
After the atomizer is inserted into the battery pole, when the battery pole realizes communication with the atomizer, the chip 1 controls the heating element L to generate heat so that the atomizer works in the first mode, and when the battery pole does not realize communication with the atomizer, the chip 1 controls the heating element L to generate heat or not generate heat so that the atomizer works in the second mode. Specifically, in one embodiment, if the battery pole realizes that the battery pole communicates with the atomizer, it indicates that the atomizer and the battery pole can be matched, and indicates that the atomizer and the battery pole are the same model of product produced by the same manufacturer, and at this time, the atomizer can be controlled to generate heat according to the model of the atomizer so as to work in the first mode; if the battery pole does not realize the communication with the atomizer, the atomizer and the battery pole cannot be matched, and the atomizer and the battery pole are not the same model products produced by the same manufacturer, and the heating of the atomizer and the battery pole can be controlled or forbidden by default parameters so as to enable the atomizer and the battery pole to work in the second mode.
Specifically, the atomizer further comprises: a first input terminal m1 and a second input terminal m2. When the atomizer is inserted into the battery rod, the atomizer is electrically connected with the battery rod through the first input end m1 and the second input end m2. In the present embodiment, the heating element L and the control switch M of the chip 1 are connected in series between the first input terminal M1 and the second input terminal M2, and the communication interface SDA of the package body is connected to the first input terminal M1.
Optionally, the atomizer further comprises: the capacitor C connects the power interface VDD of the package to ground through the capacitor C.
Specifically, a first end of the heating element L is connected to the first input terminal M1, and a second end is connected to a first path terminal of the control switch M. The first end of the capacitor C is connected with the power interface VDD, and the second end of the capacitor C is grounded.
Fig. 4 is a schematic structural diagram of a second embodiment of the atomizer of the present invention. Compared to the first embodiment of the atomizer shown in fig. 3, the difference is that: the present embodiment further includes a first switch M' connected in parallel with the control switch M. Specifically, the control end of the first switch M ' is connected to the switch control interface vg_scl, the first path end of the first switch M ' is connected to the switch path interface VDS and the first path end of the control switch M, and the second path end of the first switch M ' is connected to the ground interface GND and the second path end of the control switch M.
In this embodiment, the first switch M' is connected in parallel with the control switch M, thereby increasing the on-current. For example, if the current passing through the heating element L is 10A, and the control switch M can only bear 6A at maximum, the chip 1 turns on the control switch M after the authentication operation is completed, and then when the PWM signal is used to heat the heating element L, the control switch M cannot bear 10A, so that the electronic atomization device cannot perform normal atomization. In this embodiment, since the expansion interface NC or the ground interface GND is reserved, the first switch M 'is externally connected, and the control switch M in the chip 1 is connected in parallel with the first switch M', so as to increase the on current.
Fig. 5 is a schematic structural diagram of a third embodiment of the atomizer of the present invention. Compared to the first embodiment of the atomizer shown in fig. 3, the difference is that: the present embodiment further comprises a second switch m″ connected in series with the control switch M. Specifically, the control end of the second switch m″ is connected to the switch control interface vg_scl, the first path end of the second switch m″ is connected to the ground interface GND and the second path end of the control switch M, and the second path end of the second switch m″ is connected to the second input end M2. Specifically, in this embodiment, the heating element L, the control switch M, and the second switch m″ are sequentially connected in series between the first input terminal M1 and the second input terminal M2.
In this embodiment, when only the control switch M is stored in the chip 1, if the atomizer is reversely connected to the battery pole, the heating element L is grounded, and when the second path end (source) of the control switch M is connected to the power supply voltage VDD, the power supply voltage VDD is reversely conducted by forming a path through the body diode of the control switch M. When only the second switch M 'is stored in the chip 1, if the atomizer is reversely connected into the battery rod, the body diode of the second switch M' is in a cut-off state, so that the atomizer can be prevented from being reversely conducted to damage the atomizer. Therefore, the heating element L, the control switch M, and the second switch m″ are sequentially connected in series between the first input terminal M1 and the second input terminal M2, so that the control switch M can be prevented from reverse conduction.
The working modes of the atomizers of the second embodiment and the third embodiment are similar to those of the first embodiment, and are not described herein for brevity.
Fig. 6 is a schematic structural diagram of a fourth embodiment of the atomizer of the present invention. In this embodiment, the heating element L and the control switch M are connected in parallel between the first input terminal M1 and the second input terminal M2. Specifically, one end of the heating element L is connected to the first input end m1, the switch channel interface VDS of the package body is connected to the first input end m1, and the other end of the heating element L is connected to the ground interface GND of the package body, in this embodiment, the communication interface SDA of the package body is connected to the first input end m1, the capacitor C is connected to the power supply interface VDD of the package body and grounded, specifically, the first end of the capacitor C is connected to the power supply interface VDD, and the second end is grounded. Specifically, a first path end of the control switch M is connected to the first input end M1, a second path end of the control switch M is connected to the second input end M2, and a control end of the control switch M is connected to the control end n1 of the drive control circuit 13.
In this embodiment, if the battery pole and the atomizer are in communication, the battery pole may heat the heating element L according to the heating parameter stored in the atomizer, so that the atomizer works in the first mode. In this embodiment, since the heating element L is connected in parallel with the control switch M, if the battery pole is unsuccessful in communication with the atomizer, the heating element L can be heated only by sending the PWM signal from the battery pole, so that the atomizer works in the second mode. In this embodiment, the heating element L is connected in parallel with the control switch M, and the battery rod can determine whether the battery rod and the atomizer are products shipped from the same manufacturer by determining whether the battery rod and the atomizer can communicate successfully, so as to identify the atomizer, but the function of prohibiting the use of the atomizer if the battery rod and the atomizer are not matched cannot be realized.
The chip for the atomizer can realize the series connection of the heating element and the control switch and the parallel connection of the heating element and the control switch, and can realize different functions according to different software settings, thereby meeting different use requirements of the atomizer in different use environments.

The direction identifying unit 10 shown in this embodiment is the same as the direction identifying unit 10 in the battery pole described in fig. 9, and will not be described again here.
If the direction identifying unit 10 identifies that the atomizer is 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 with the output end N of the driving circuit; the second switching port P0' outputs a high level signal, so that the tenth switch T10 is turned on, the point B is grounded, and the second connection pin h2 is grounded.
If the direction identification unit 10 identifies 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 with the output end N of the driving circuit; the second switching port P0' outputs a low level signal, so 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 pole, when the PWM signal is output 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 the sources of the seventh switch T7 and the ninth switch T9 are supplied with power. At this time, since the eighth switch T8 is turned off, the gate of the seventh switch T7 is clamped low by the first diode D1 and the first switching port P0, thereby turning on the seventh switch T7. The first capacitor C1 is charged to the voltage difference Δv between the gate and the source of the seventh switch T7, so that the current is input to the first input terminal m1 of the atomizer through the seventh switch T7, that is, the output terminal N of the driving circuit is input 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 has only the fifth resistor R5 discharging channel, the voltage across the first capacitor C1 is not rapidly turned off, so that the seventh switch T7 is kept continuously turned on, that is, the output terminal N of the driving circuit is input to the first input terminal m1 of the atomizer, so as to ensure that the twelfth switch T12 and the seventh resistor R7 channel can collect parameters of the heating element L.
When the atomizer is reversely inserted into the battery pole, when the PWM signal is output 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 the sources of the seventh switch T7 and the ninth switch T9 are supplied with power. At this time, since the tenth switch T10 is turned off, the gate of the ninth switch T9 is clamped low by the second diode D2 and the second switching port P0', thereby turning on the ninth switch T9. The second capacitor C2 is charged to the voltage difference Δv between the gate and the source of the ninth switch T9, so that the current is input to the second input terminal m2 of the atomizer through the ninth switch T9, that is, the output terminal N of the driving circuit is input 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 has only the discharge channel of the sixth resistor R6, the voltage across the second capacitor C2 is not rapidly turned off, so that the ninth switch T9 is kept continuously turned on, that is, the output terminal N of the driving circuit is input to the second input terminal m2 of the atomizer, so as to ensure that the twelfth switch T12 and the seventh resistor R7 channels can collect parameters of the heating element L.
Referring to fig. 12, a schematic view of the structure of the atomizer shown in fig. 3 being inserted into the battery stem shown in fig. 9 is shown.
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 power supply voltage VDD, the first detection communication port P1 detects a jump signal, and then the driving chip MCU of the battery rod is awakened. At this time, the first detection communication port P1 and the second detection communication port P1' of the driving chip 100 of the battery pole respectively send a string of data to the atomizer through the first connection pin h1 and the second connection pin h2, and if the first detection communication port P1 detects a feedback signal, it indicates that the atomizer is being inserted into the battery pole; if the second detection communication port P1' detects the feedback signal, it indicates that the atomizer is reversely inserted into the battery pole.
Specifically, in another embodiment, when it is determined that the resistance value collected by the first detection communication port P1 is in the first preset range and the resistance value collected by the second detection communication port P1' is in the second preset range, it is determined that the atomizer inserted into the battery rod is inserted. Conversely, the reverse plug is performed, that is, if the resistance value collected by the first detection communication port P1 is the internal resistance (for example, greater than 3 kilohms) 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, the atomizer is indicated to be inserted into the battery rod; if the resistance value collected by the first detection communication port P1 is the resistance value (e.g. less than 3 ohms) of the heating element L, and the resistance value collected by the second detection communication port P1' is the internal resistance (e.g. greater than 3 kiloohms) of the driving control circuit 13, the atomizer is reversely inserted into the battery rod.
This embodiment will be described taking as an example that the atomizer is being inserted into the battery stem. Specifically, the first connection pin h1 of the battery rod is connected with the first input end m1 of the atomizer, and the second connection pin h2 of the battery rod is connected with the second input end m2 of the atomizer. In this embodiment, the first switch T1 is controlled to be turned off by the first switch port P0, and the second switch T2 is controlled to be turned on by the second switch port P0', so that the point B is grounded. At this time, the battery rod supplies the power voltage VDD to the first input terminal m1 of the atomizer through the first driving module 31, and thus heats the heating element L.
Fig. 13 is a schematic view showing the structure of the atomizer shown in fig. 3 which is reversely inserted into the battery pole shown in fig. 9.
Specifically, the first switch T1 is set to be turned on, and 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 supply voltage VDD, and the second detection communication port P1' detects a jump signal, so as to wake up the driving chip MCU of the battery rod. At this time, the first detection communication port P1 and the second detection communication port P1' of the driving chip 100 of the battery pole respectively send a string of data to the atomizer through the first connection pin h1 and the second connection pin h2, and if the first detection communication port P1 detects a feedback signal, it indicates that the atomizer is being inserted into the battery pole; if the second detection communication port P1' detects the feedback signal, it indicates that the atomizer is reversely inserted into the battery pole.

Conversely, the reverse plug is performed, that is, if the resistance value collected by the first detection communication port P1 is the internal resistance (for example, greater than 3 kilohms) 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, the atomizer is indicated to be inserted into the battery rod; if the resistance value collected by the first detection communication port P1 is the resistance value (e.g. less than 3 ohms) of the heating element L, and the resistance value collected by the second detection communication port P1' is the internal resistance (e.g. greater than 3 kiloohms) of the driving control circuit 13, the atomizer is reversely inserted into the battery rod.
This embodiment will be described taking as an example that the atomizer is being inserted into the battery stem. Specifically, the first connection pin h1 of the battery rod is connected with the second input end m2 of the atomizer, and the second connection pin h2 of the battery rod is connected with the first input end m1 of the atomizer. In this embodiment, the first switch T1 is controlled to be turned on by the first switch port P0, and the second switch T2 is controlled to be turned off by the second switch port P0', so that the point a is grounded. At this time, the battery rod supplies the power voltage VDD to the first input terminal m1 of the atomizer through the second driving module 32, thereby heating the heating element L.
The specific working principle of the atomizer shown in fig. 3, which is inserted into or inserted into the battery rod shown in fig. 11, is referred to above, and will not be described in detail.
Fig. 14 is a schematic structural view of a fifth embodiment of the atomizer of the present invention. Specifically, in comparison with the nebulizer shown in fig. 3, a memory 14 is also provided in the chip 1, specifically, the memory 14 is provided in the drive control circuit 13. It should be noted that, for brevity, the technical features shown in fig. 3 are not fully shown in fig. 14, and the technical features not shown may be directly referred to the description of fig. 3.
The memory 14 has stored therein a discard parameter. The discard parameter is used to identify whether the nebulizer can be used. Specifically, if the discard parameter stored in the memory 14 is valid, it indicates that the nebulizer cannot be used; if the discard parameters stored in the memory 14 are not valid, this indicates that the nebulizer can be used.
Specifically, the communication interface SDA of the chip 1 communicates with the battery lever. Specifically, when the nebulizer is inserted in the battery pole, the nebulizer authenticates with the battery pole through the communication interface SDA. If the authentication is successful, the battery lever reads the discard parameters stored in the memory 14 to determine whether the nebulizer can be used.
Specifically, when the nebulizer is inserted into the battery pole, the battery pole sends data to the communication interface SDA of the nebulizer, and if feedback data from the nebulizer is received, authentication is successful. The battery bar reads the discard parameters stored in the memory 14 of the nebulizer via the communication interface SDA.
Specifically, when the rejection parameter is in the 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 drive 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, so that 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 used normally. Specifically, the driving control circuit 13 controls the control switch M to be turned on, and the battery rod heats the heating element L at this time, so that the atomizer is normally used.
Specifically, in one embodiment, the memory 14 includes a data protection area and a data read-write area, where the data read-write area stores current pumping parameters and discard parameters; the data protection area stores default pumping parameters and default heating parameters. The default suction parameters may be, for example, the longest suction time after the priming of the atomizer, and the maximum number of suction times. The default heating parameter may be, for example, a corresponding heating power, heating temperature profile, etc. The current suction parameter may be, for example, the current time of suction or the current number of times of suction of the nebulizer.
The nebulizer can be used when the discard parameter is in an inactive state. The default heating parameters are obtained by the battery stem, which heats the heating element L according to the default heating parameters, thereby enabling the atomizer to be used normally. Specifically, when the battery rod heats the heating element L, the driving chip can control and output corresponding heating power so that the heating element L can reach a preset temperature curve, and therefore the atomized matrix is prevented from being excessively heated.
In an embodiment, the drive control circuit 13 further comprises a timer 15. The drive control circuit 13 controls the control switch M to be turned off at predetermined intervals of time in normal use of the atomizer. Specifically, after the drive control circuit 13 controls the control switch M to be turned on, the control switch M is turned off at regular intervals of the timer. Or in another embodiment, a predetermined code is written in the drive control circuit 13, which is capable of controlling the drive control circuit 13 to control the control switch M to be turned off at regular intervals.
In an embodiment, when the fact that the atomizer stops sucking is detected, the scrapping parameter and the current sucking parameter of the atomizer are updated, and if the updated current sucking parameter reaches the default sucking parameter, the scrapping parameter in the atomizer is updated to be in a valid state.
Specifically, the microphone or the airflow sensor is arranged in the battery rod, when the microphone or the airflow sensor detects that airflow passes through, the battery rod is awakened from a sleep state, a conduction signal is sent to the atomizer, after the atomizer receives a conduction instruction, the atomizer controls the control switch M to be conducted through the drive control circuit 13, and then the battery rod obtains default heating parameters to heat the heating element L, so that the atomizer is normally used. Therefore, different atomizing matrixes can be atomized by adopting different heating parameters, and the user experience degree is improved. When the microphone or the air flow sensor detects that the air flow is stopped, i.e. the suction is stopped, the battery rod stops heating the heating element L, and the 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 sucking the electronic atomizing device, the battery lever accumulates the sucked time or number of times with the sucked time or number of times in the current suction parameter, and updates the current suction parameter by using the accumulated result.
Optionally, after updating the current pumping parameter, comparing the updated current pumping parameter with a default pumping time, when the updated current pumping parameter reaches the default pumping parameter, indicating that the pumping time or pumping frequency of the atomizer is used up, and updating the scrapping parameter in the atomizer to be in an effective state at the moment so as to lock the atomizer and prevent the atomizer from being used. 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 airflow passing is detected next time, the atomizer is continuously powered to heat the heating element L.
Further, if the discard parameter of the atomizer is updated to be in the valid state, the driving control circuit 13 controls the control switch M to be in the off state all the time, so that the atomizer which can prohibit the user from injecting oil privately cannot be used.
Referring to fig. 15, a schematic functional block diagram of a second embodiment of a battery pole according to the present invention is shown, in which the battery pole includes a driving chip 300, a detection communication port D is provided on the driving chip 300, and when a nebulizer is inserted into the battery pole, the detection communication port D communicates with the nebulizer inserted into the battery pole, and the discard parameter in the nebulizer is read, so as to determine whether the nebulizer can be used according to the discard parameter.
Specifically, please refer to fig. 16, which is a flow chart illustrating an embodiment of a method for using an electronic atomization device according to the present invention, wherein the electronic atomization device includes an atomizer shown in fig. 14 and a battery pole shown in fig. 15, and specifically includes:
Step S11: and obtaining the scrapping parameters stored in the atomizer.
Specifically, the atomizer is provided with a memory 14, 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 a communication port D, and if authentication is successful, the battery rod reads the scrapping parameters. Specifically, the battery pole further includes: the identification circuit 50 detects the communication port D to communicate with the nebulizer through the identification circuit 50.
Step S12: determining whether the nebulizer can be used according to the discard parameter.
Specifically, when the read discard parameter indicates invalid, it indicates that the nebulizer can be used, and when the read discard parameter indicates valid, it indicates that the nebulizer cannot be used.
Referring 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 discard 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 a specific embodiment, the default pumping parameters may be, for example, a maximum pumping time, a maximum number of pumping times after priming the atomizer. The default heating parameter may be, for example, a corresponding heating power, heating temperature profile, etc.
Specifically, the battery pole further includes: the driving circuit 40, the driving circuit 40 is connected with the driving chip 300 and the identification circuit 50. When the read discard 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 the driving circuit 40 according to the default heating parameter so that the atomizer can be used normally.
In an embodiment, the driving chip 300 is the driving chip 100 shown in fig. 9, the detection communication port D of the driving chip 300 is the first detection communication port P1 or the second detection 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 detection 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 detection 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 detection communication port P1', the second identification module 12, the second driving module 32 and the driving chip 100.
It will be appreciated that in other embodiments, the electronic atomizing device may also include the battery pole shown in fig. 9, and at this time, before step S11, the steps further include: and identifying whether the atomizer is in forward insertion or reverse insertion, and selecting a detection communication port, a driving module and an identification module corresponding to the atomizer.
It will be appreciated that in other embodiments, the electronic atomizing device may also include a battery pole as shown in fig. 11, and the specific operation thereof is similar and will not be described herein.
Step S22: it is detected whether the nebulizer stops pumping.
Specifically, the microphone or the airflow sensor is arranged in the battery rod, when the microphone or the airflow sensor detects that airflow passes through, the battery rod is awakened from a sleep state, a conduction signal is sent to the atomizer, after the atomizer receives a conduction instruction, the control switch M is controlled to be conducted through the drive control circuit 13, and then the battery rod obtains default heating parameters to heat the heating element L, so that the atomizer is normally used, and when the microphone or the airflow sensor detects that no airflow passes through, the atomizer stops sucking.
Step S23: and when the fact that the atomizer stops sucking is detected, updating the current sucking times of the atomizer and the scrapping parameters.
When the microphone or the airflow sensor detects that no air flows through, the atomizer stops sucking, the battery rod stops heating the heating element L, and the current sucking parameter in the atomizer is updated according to the sucking time or the sucking times of the sucking process. For example, when it is detected that the user stops sucking the electronic atomizing device, the battery lever accumulates the sucked time or number of times with the sucked time or number of times in the current suction parameter, and updates the current suction parameter by using the accumulated result.
Optionally, after updating the current pumping parameter, comparing the updated current pumping parameter with a default pumping time, when the updated current pumping parameter reaches the default pumping parameter, indicating that the pumping time or pumping frequency of the atomizer is used up, and updating the scrapping parameter in the atomizer to be in an effective state at the moment so as to lock the atomizer and prevent the atomizer from being used. 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 airflow passing is detected next time, the atomizer is continuously powered to heat the heating element L.
Further, if the discard parameter of the atomizer is updated to be in the valid state, the driving control circuit 13 controls the control switch M to be in the off state all the time, so that the atomizer which is filled with oil by the user can be prevented from being used.
According to the electronic atomization device provided by the invention, the chip is arranged in the atomizer, and the atomizer can communicate with the battery rod through the communication interface arranged on the chip. When the battery rod realizes that the battery rod is in communication with the atomizer, the atomizer works in a first mode; when the battery lever does not enable its communication with the atomizer, the atomizer operates in the second mode. Specifically, if the battery pole realizes the communication between the battery pole and the atomizer, the battery pole and the atomizer can be indicated to be factory products of the same manufacturer, and if the battery pole does not realize the communication between the battery pole and the atomizer, the battery pole and the atomizer can be indicated to be factory products of the same manufacturer.

Therefore, the battery rod and the atomizer can work normally in the forward or reverse plug mode.
