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. In this embodiment, heating element L is connected in parallel with control switch M, and the battery pole can judge whether battery pole and atomizer are the product that same producer left the factory through judging whether battery pole and atomizer can communicate successfully to reach the discernment to the atomizer, nevertheless can not realize if battery pole and atomizer mismatch and forbid the function of using the atomizer.

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.

Fig. 12 is a schematic view of the atomizer shown in fig. 3 being inserted into the battery rod shown in fig. 9.

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.

Please refer to fig. 14, which is a schematic structural diagram of an embodiment of the electronic atomization device of the present invention, specifically, the electronic atomization device includes a battery rod and an atomizer, the battery rod includes a driving chip 100, a driving circuit 60 and an identification circuit 70, wherein the driving circuit 60 may be the first driving module 31 shown in fig. 9, and the identification circuit 70 may be the first identification module 11 shown in fig. 9, and the detailed description refers to the description of fig. 9.

The atomizer is the atomizer shown in fig. 3, and the detailed description is provided with reference to the description of fig. 3. In this embodiment, the nebulizer comprises a chip 1, the chip 1 being adapted to communicate with a battery rod when the nebulizer is inserted into the battery rod; in particular, the chip 1 comprises a communication port SDA, through which the chip 1 can communicate with the battery lever. The atomizer also comprises a capacitor C, the capacitor C is connected with the chip 1, and when the atomizer is inserted into the battery rod, the capacitor C is charged according to communication signals between the atomizer and the battery rod so as to supply power to the chip by using the capacitor C, and therefore the chip works normally.

Specifically, referring to fig. 15, fig. 15 is a schematic flow chart of an embodiment of a method for using the atomizer shown in fig. 14, including:

step S11: the atomizer communicates with the battery stem when the atomizer is inserted into the battery stem.

Step S12: the electric capacity in the atomizer is charged according to the communication signal between atomizer and the battery pole, and then utilizes electric capacity to supply power for the atomizer to make the atomizer normally work.

Specifically, a capacitor C in the atomizer is connected to the chip 1, when the atomizer is inserted into the battery rod, the first resistor R1 in the identification circuit 70 of the battery rod divides voltage with the resistor R in the atomizer, a jump signal is generated at the detection communication port P1 of the battery rod, the driving chip 100 in the battery rod is awakened, and the driving circuit of the battery rod is continuously turned on to charge the capacitor C in the atomizer. After the capacitor C is charged, the capacitor C can be used for supplying power to the chip 1, so that the chip 1 works normally.

In particular, the chip 1 comprises a communication interface SDA and a power interface VDD, which is connected to the capacitor C. The communication interface SDA and the power interface VDD of the chip 1 are connected by internal wiring. When the atomizer communicates with the battery lever, the capacitor C is charged by the internal wiring through the communication interface SDA.

In one embodiment, the detection communication port P1 or the drive port P2 or P3 of the battery lever can send a communication signal to the nebulizer when the battery lever and the nebulizer are in operation. For example, the battery pole may transmit the communication signal in a BMC coding manner.

When the communication signal received by the atomizer is a data storage command and data is stored, after the communication signal is received by the atomizer, the capacitor C can receive the charging voltage provided by the battery rod within a first preset time period so as to be charged and store electric energy, so that the capacitor C can supply power to the chip 1 by the stored electric energy, and the chip 1 normally completes data storage and returns a corresponding communication signal. For example, if the battery lever needs to update the current pumping parameters in the nebulizer, the communication signal received by the nebulizer is a data storage command and the updated current pumping parameters. The atomizer stores the updated current pumping parameters according to the data storage command, and at the moment, in the data storage process, the capacitor C can receive the charging voltage provided by the battery rod within a first preset time period so as to be charged and store electric energy, so that the capacitor C can supply power to the chip 1 through the stored electric energy, the chip 1 can be normally provided with electric energy in the data storage process, and corresponding communication signals are returned after the data storage is completed.

When the chip 1 writes the stored data into the internal memory, a large current, for example, 5mA to 30mA is required, and the battery rod continuously supplies a high voltage and a large current to the atomizer. After the chip 1 finishes writing the stored data, the battery rod stops supplying power to the atomizer, so that the driving control circuit 13 can keep the voltage stable when the stored data is written.

When the communication signal received by the nebulizer is a normal command or a data reading command, after the nebulizer receives the communication signal, the capacitor C can receive the charging voltage provided by the battery rod to be charged and store electric energy in a second predetermined time period, so that the capacitor C can supply power to the chip 1 by the stored electric energy, so that the chip 1 performs a corresponding operation according to the communication signal and returns a corresponding communication signal. For example, if the communication signal received by the nebulizer is to read the default suction parameter, after the nebulizer receives the read default suction parameter, the capacitor C receives the charging voltage provided by the battery rod within a second predetermined time period of reading the default suction parameter to be charged and store the electric energy, so that the capacitor C can supply power to the chip 1 by the stored electric energy, so that the chip 1 performs the corresponding operation according to the communication signal and returns the corresponding communication signal.

The first preset time period is greater than the second preset time period. The first preset time period may be, for example, 4 × x ms (x is the number of bytes to be saved, and 4ms is the time required for saving a single byte), and the second preset time period may be, for example, 1ms (the time required for processing such as data verification).

In one embodiment, when the communication signal received by the nebulizer is a data storage command and data storage, the communication signal returned by the nebulizer is a data write completion signal. For example, if the nebulizer receives the updated current pumping parameter and the updated current pumping parameter, the nebulizer updates the current pumping parameter and then returns a data write completion signal to the battery rod.

When the communication signal received by the atomizer is a data reading command, the communication signal returned by the atomizer is a data signal to be read. For example, if the nebulizer receives an instruction to read the default puff parameters, the nebulizer returns the stored default puff parameters to the battery stem.

When the communication signal received by the atomizer is a common command, the communication signal returned by the atomizer is the common command. The generic command is data or a command sent by the battery lever to the nebulizer.

In an embodiment, when the nebulizer returns a corresponding communication signal, when the communication signal is at the first logic level, the capacitor C can receive the charging voltage provided by the battery rod for a third preset time period to be charged and store the electric energy, so that the capacitor C can supply power to the chip 1 by the stored electric energy, so that the chip 1 can normally communicate with the battery rod. Specifically, the first logic level is a logic high level "1", that is, if the communication signal returned from the nebulizer to the battery rod has a logic high level "1", the battery rod continuously provides the charging voltage to the capacitor C through the driving circuit 60 for a third preset time period, so that the capacitor C is charged and stores electric energy. Specifically, in an embodiment, the third preset time period may be, for example: and 10-30 us, wherein the third preset time period is less than the duration of the communication signal at the first logic level. It can be understood that the nebulizer can communicate with the battery rod by adopting a BMC coding mode, a transition from a high level to a low level in the BMC coding mode represents 1, and a transition from the low level to the high level represents 0, that is, the battery rod can communicate with the nebulizer only by identifying a transition signal, so that the battery rod can charge the capacitor C through the driving circuit 60 during the period when the nebulizer transmits the high level signal of the BMC coding, and the charging of the capacitor C can be realized while the communication between the battery rod and the capacitor C is not hindered.

In particular, the atomizer further comprises a heating element L. The heating element L is connected to the chip 1. When the atomizer is pumped, the atomizer receives a PWM signal with a preset frequency to heat the heating element L, wherein the preset frequency is 1 KHz-200 KHz. In a preferred embodiment, the predetermined frequency is 20 KHz. The capacitor C is charged when the PWM signal is at the first logic level. And discharging when the PWM signal is at the second logic level, wherein the maximum charging time of the capacitor C is shorter than the duration time of the PWM signal at the first logic level, and the minimum discharging time of the capacitor C is longer than the duration time of the PWM signal at the second logic level.

Specifically, the conventional PWM signal of the electronic atomizer has a period of 10ms (100Hz), and when the resistance is small/the power is small/the voltage is high, the extreme case of a small duty ratio occurs. In extreme conditions, the duty cycle is close to 14%, the high duration is 1.4ms and the low duration is 8.6 ms. The drive control circuit 13 and the capacitor C of the atomizer have only 1.4ms of charging time, and when the power supply voltage is low, the operating voltage of the drive control circuit 13 has the risk of quickly powering down to the extreme low voltage, so that the normal operating state of the drive control circuit 13 cannot be maintained to keep the conduction of the control switch M in the atomizer.

In view of this problem, the frequency of the PWM signal can be increased in the above manner, so that even if the duty ratio is the same, the discharge time of the capacitor C of the drive control circuit 13 of the atomizer is shortened due to the shortened heating period, and the voltage fluctuation across the capacitor C is reduced, so that the operating voltage of the drive control circuit 13 is stabilized.

As can be seen from the charging formula I Δ T ═ Δ U ═ C ═ Q of the capacitor C,

wherein I is the current of the battery pole charging the capacitor C through the PWM signal, Δ U is the differential pressure of the capacitor C from 1.8V to the operating voltage of the heating element L, C is the capacity of the capacitor C, and Δ T is the time of charging the capacitor C. Considering practical application, when the current is minimum and the charging voltage difference is maximum, the charging time is longest, and the maximum charging time is only less than the high level time of the duty ratio, so that the capacitor can be ensured to be fully charged in each period. In the current product, the discharge current I of the battery rod is minimum 3A, Δ U corresponds to 1.9V, and Δ Tmax is 0.63 × C, and when the capacity C of the capacitor C takes a value of 1uF, Δ Tmax is 630 ns. When the frequency of the PWM signal corresponds to 200KHz, Δ Tmax is less than the logic high duration of the PWM signal even at the minimum duty cycle, ensuring that the capacitor C in the nebulizer is fully charged.

Likewise, the capacitance Cdischarge equation can be used

Where I is the current consumed by the driving control circuit 13, Δ U is the voltage difference between the capacitor C and 1.8V after the capacitor C is discharged, C is the capacitance of the capacitor C, and Δ T is the discharge time of the capacitor C. Considering practical application, when the consumption current I is maximum and the discharge differential pressure delta U is minimum, the discharge time is shortest, and the chip 1 can be ensured to work stably as long as the shortest time is longer than the low level time of the duty ratio. According to the maximum 50uA working current of the chip 1 and the 0.3V discharging pressure difference, the delta Tmin is 6000 xC, when the capacity C of the capacitor C is 1uF, the delta Tmin is 6ms, the discharging time is longer than the period of 1KHz of PWM signal working, and the working stability of the chip 1 can be ensured.

The preferred predetermined frequency of the PWM signal is 20KHz, mainly considering that the communication port ADC sampling is stable within 50 us.

The nebulizer shown in this embodiment can communicate with the battery rod by using a BMC coding method, where a transition from a high level to a low level in the BMC coding method represents 1, and a transition from the low level to the high level represents 0, and during a period of transmitting a high level signal of the BMC coding, the battery rod charges a capacitor C of the nebulizer through the driving circuit 60 to store electric energy, so as to ensure that the voltage of the chip 1 is stable during communication. Specifically, when the chip 1 writes data in the internal memory, the current required is relatively large, and at this time, the driving circuit 60 provides high voltage and large current for the chip 1 of the nebulizer, so that the voltage stability of the chip 1 during communication can be further ensured. When the atomizer is pumped, the atomizer receives a PWM signal with a preset frequency to heat the heating element L, wherein the preset frequency is 1 KHz-200 KHz. In a preferred embodiment, the predetermined frequency is 20 KHz. This ensures that the voltage remains stable during heating of the heating element L.

Fig. 16 is a schematic flow chart illustrating an embodiment of a method for using the battery rod in fig. 14. The battery rod is used for driving the atomizer inserted in the battery rod and supplying power to the atomizer. Referring to fig. 14, the battery rod includes: a driving chip 100 and a driving circuit 60, wherein the driving circuit 60 is connected with the driving chip 100. The driving chip 100 communicates with the atomizer inserted therein through the driving circuit 60, and charges the capacitor C in the atomizer according to a communication signal between the atomizer and the battery rod, so that the atomizer works normally.

Specifically, the method comprises the following steps:

step S21: the battery stem communicates with the atomizer when the atomizer is inserted into the battery stem.

When the atomizer is inserted into the battery rod, the battery rod sends a communication signal to the atomizer through the detection communication port. Specifically, the driving chip 100 further includes a detection communication port P1, and the battery bar includes: an identification circuit 70 and a drive circuit 60, wherein the identification circuit 70 is connected with a detection communication port P1 and the drive circuit 60, when the atomizer is inserted into the battery rod, the battery rod sends communication signals to the atomizer through the detection communication port P1 or the drive ports P2 and P3.

Step S22: and charging the atomizer according to the communication signal so as to enable the atomizer to work normally.

Specifically, when the communication signal is a data storage command and data is stored, the battery rod provides a charging voltage to the atomizer within a first predetermined time period to charge the capacitor C of the atomizer, and receives a corresponding returned communication signal after the atomizer normally completes storage of the data.

For example, if the communication signal sent by the battery rod is a command for updating the current pumping parameter in the atomizer, and the stored data is the updated current pumping parameter, the atomizer stores the updated current pumping parameter according to the data storage command, at this time, during the data storage process, the battery rod provides a charging voltage to the capacitor C within a first predetermined time period so that the capacitor C is charged and stores electric energy, so that the capacitor C can supply power to the chip 1 by the stored electric energy, so that the chip 1 can be normally provided with electric energy during the data storage process, and return a corresponding communication signal after the data storage is completed.

When the communication signal is a common command or a data reading command, the battery rod provides a charging voltage for the atomizer in a second preset time period to charge the capacitor C of the atomizer, and receives a returned corresponding communication signal after the atomizer performs corresponding operation according to the communication signal.

For example, if the communication signal sent by the battery rod is to read the default pumping parameter, after the nebulizer receives the read default pumping parameter, the battery rod provides the charging voltage to the capacitor C within a second predetermined time period after the reading of the default pumping parameter, so that the capacitor C is charged and stores electric energy, and thus the capacitor C can supply power to the chip 1 by the stored electric energy, so that the chip 1 performs a corresponding operation according to the communication signal and returns a corresponding communication signal.

In one embodiment, when the communication signal sent by the battery rod is a data storage command and data is stored, the communication signal returned by the atomizer is a data writing completion signal. For example, if the communication signal sent by the battery rod is the updated current pumping parameter and the updated current pumping parameter, the battery rod receives the return data write-in completion signal after the atomizer updates the current pumping parameter.

When the communication signal sent by the battery rod is a data reading command, the returned response communication signal received by the battery rod is a data signal to be read. For example, if the communication signal sent by the battery stick is an instruction to read the default pumping parameters, the communication signal received by the battery stick in response to the return is the default pumping parameters.

When the communication signal sent by the battery rod is a normal command, the returned response communication signal received by the battery rod is a normal command. The generic command is data or a command sent by the battery lever to the nebulizer.

In an embodiment, when the battery lever receives the corresponding communication signal, the battery lever provides a charging voltage to the nebulizer for a third preset time period to charge a capacitance of the nebulizer when the communication signal is at the first logic level. Specifically, the first logic level is a logic high level "1", that is, if the communication signal received by the battery stick has a logic high level "1", the battery stick continuously provides the charging voltage for the capacitor C through the driving circuit 60 for a third preset time period, so that the capacitor C is charged and stores electric energy. Specifically, in an embodiment, the third preset time period may be, for example: and 10-30 us, wherein the third preset time period is less than the duration of the communication signal at the first logic level.

In one embodiment, when the atomizer is detected to be sucked, the battery rod sends a PWM signal with a preset frequency to heat a heating element of the atomizer, wherein the preset frequency is 1 KHz-200 KHz. In a preferred embodiment, the predetermined frequency is 20 KHz. The capacitor C is charged when the PWM signal is at the first logic level. And discharging when the PWM signal is at the second logic level, wherein the maximum charging time of the capacitor C is shorter than the duration time of the PWM signal at the first logic level, and the minimum discharging time of the capacitor C is longer than the duration time of the PWM signal at the second logic level.

wherein I is the current of the battery pole charging the capacitor C through the PWM signal, Δ U is the differential pressure of the capacitor C from 1.8V to the operating voltage of the heating element L, C is the capacity of the capacitor C, and Δ T is the time of charging the capacitor C. Considering practical application, when the current is minimum and the charging voltage difference is maximum, the charging time is longest, and the maximum charging time is only less than the high level time of the duty ratio, so that the capacitor can be ensured to be fully charged in each period. In the current product, the discharge current I of the battery rod is minimum 3A, Δ U corresponds to 1.9V, and Δ Tmax is 0.63 × C, and when the capacity C of the capacitor C takes a value of 1uF, Δ Tmax is 630 ns. When the PWM signal frequency corresponds to 200KHz, Δ Tmax is less than the logic high duration of the PWM signal even at the minimum duty cycle, ensuring that the capacitor C in the nebulizer is fully charged.

Likewise, the capacitance Cdischarge equation can be used

The atomizer shown in this embodiment can adopt a BMC coding mode to communicate with the battery rod, and during the transmission of a high-level signal, the battery rod charges the capacitor C of the atomizer through the driving circuit 60 to store electric energy, thereby ensuring the voltage stability of the chip 1 during the communication. Specifically, when the chip 1 writes data in the internal memory, the current required is relatively large, and at this time, the driving circuit 60 provides high voltage and large current for the chip 1 of the nebulizer, so that the voltage stability of the chip 1 during communication can be further ensured. When the atomizer is pumped, the atomizer receives a PWM signal with a preset frequency to heat the heating element L, wherein the preset frequency is 1 KHz-200 KHz. In a preferred embodiment, the predetermined frequency is 20 KHZ. This ensures that the voltage remains stable during heating of the heating element L.
