[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0038] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the first embodiment of the chip for an atomizer provided by the present invention. Specifically, the chip 1 includes a package body 12, and a communication interface SDA is provided on the package body 12. The communication interface SDA is used to determine whether the battery rod can communicate with the atomizer when the atomizer is inserted into the battery rod. When the battery rod realizes communication with the atomizer, the atomizer operates in the first mode; when the battery rod fails to realize communication with the atomizer, the atomizer operates in the second mode.

[0039] Specifically, the chip 1 further includes: a control switch M and a drive control circuit 13, and both the control switch M and the drive control circuit 13 are arranged in the package body 12. Among them, the control end n1 of the drive control circuit 13 is connected to the control end of the control switch M, and the communication end n2 of the drive control circuit 13 is connected to the communication interface SDA to determine whether the battery rod can communicate with the atomizer through the communication interface SDA.

[0040] Specifically, the package body 12 further includes a switch path interface VDS, a ground interface GND, and a power interface VDD. Among them, the switch path interface VDS is connected to the first path end of the control switch M; the ground interface GND is connected to the second path end of the control switch M and the ground end n3 of the drive control circuit 13; the power interface VDD is connected to the power end n4 of the drive control circuit 13 and is connected to the communication interface SDA.

[0041] Among them, the package body 12 further includes a switch control interface VG_SCL, and the switch control interface VG_SCL is further connected to the control end of the control switch M.

[0042] Optionally, the chip 1 further includes: a diode D, which is arranged in the package body 12. Among them, the communication interface SDA is connected to the power interface VDD through the diode D. Specifically, the diode D is a diode, the anode of the diode is connected to the communication interface SDA, and the cathode is connected to the power end n4 of the drive control circuit 13 and is connected to the power interface VDD. In an alternative embodiment, the diode D can also be a MOSFET, a triode, etc.

[0043] Optionally, the chip 1 further includes a resistor R disposed within the package 12, wherein the communication interface SDA is connected to the ground interface GND through the resistor R. Specifically, the first end of the resistor R is connected to the communication interface SDA, and the second end is connected to the ground interface GND.

[0044] Optionally, the drive control circuit 13 further includes a memory in which preset data is stored. When the atomizer is inserted into the battery rod and the battery rod does not communicate with the atomizer within a predetermined time period, the drive control circuit 13 can control the control switch M according to the preset data or not perform any operation, so that the atomizer operates in the second mode.

[0045] Optionally, the drive control circuit 13 is an application-specific integrated circuit (ASIC). Further, the diode D can also be integrated into the ASIC formed by the drive control circuit 13.

[0046] Please refer to Figure 2 , which is a schematic structural diagram of the first embodiment of the chip for an atomizer provided by the present invention. Compared with the above Figure 1 shown first embodiment, the difference is that the chip 1 shown in this embodiment further includes an expansion interface NC, and the expansion interface NC is a reserved interface of the chip 1. Optionally, the expansion interface NC is electrically connected to the ground interface GND in the package 12.

[0047] The above Figure 2 shown chip 1 uses an SOT23-6 package, while Figure 1 shown chip 1 uses an SOT23-5 package, which can minimize costs in terms of packaging angle. And using the Figure 2 shown SOT23-6 packaging method is more conducive to the internal wiring of the chip 1. And in the above Figure 1 and Figure 2 shown chip 1, the first path end, the second path end and the control end (corresponding to the drain, source and gate respectively) of the control switch M are independently led out. In practical applications, 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.

[0048] Please refer to Figure 3 , which is a schematic structural diagram of the first embodiment of the atomizer of the present invention. Among them, the atomizer includes a heating element L and a chip 1. The chip 1 is connected to the heating element L, where the chip 1 is the chip 1 shown in any of the above Figure 1 and Figure 2 embodiments.

[0049] Among them, after the atomizer is inserted into the battery rod, when the battery rod 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. When the battery rod fails to 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 a specific embodiment, if the battery rod realizes communication with the atomizer, it means that the atomizer and the battery rod can be matched, referring to the atomizer and the battery rod being products of the same model produced by the same manufacturer. At this time, the atomizer can be controlled to generate heat according to its model to work in the first mode. If the battery rod fails to realize communication with the atomizer, it means that the atomizer and the battery rod cannot be matched, referring to the atomizer and the battery rod not being products of the same model produced by the same manufacturer. At this time, default parameters can be used to control its heating or prohibit its heating to make it work in the second mode.

[0050] Specifically, the atomizer further includes: 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 to the battery rod through the first input terminal m1 and the second input terminal m2. In this 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 12 is connected to the first input terminal m1.

[0051] Optionally, the atomizer further includes: a capacitor C, and the power supply interface VDD of the package 12 is grounded through the capacitor C.

[0052] Specifically, the first end of the heating element L is connected to the first input terminal m1, and the second end is connected to the first path end of the control switch M. The first end of the capacitor C is connected to the power supply interface VDD, and the second end is grounded.

[0053] Please refer to Figure 4 , which is a schematic structural diagram of the second embodiment of the atomizer of the present invention. Compared with Figure 3 the first embodiment of the atomizer shown, the difference is that this embodiment further includes a first switch M', and the first switch M' is 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.

[0054] In this embodiment, the first switch M' is connected in parallel with the control switch M to increase the conduction current. For example, if the current passing through the heating element L is 10A, while the control switch M can only withstand a maximum current of 6A, when the chip 1 completes the authentication operation and then turns on the control switch M to heat the heating element L using the PWM signal, the control switch M will not be able to withstand the 10A current, resulting in the electronic atomization device being unable to atomize normally. In this embodiment, due to the reserved expansion interface NC or the ground interface GND, an external first switch M' is connected, and the control switch M in the chip 1 is connected in parallel with the first switch M' to increase the conduction current.

[0055] Please refer to Figure 5 , which is a schematic structural diagram of the third embodiment of the atomizer of the present invention. Compared with Figure 3 the first embodiment of the atomizer shown, the difference is that: this embodiment further includes a second switch M", and the second switch M" is 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 terminal 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.

[0056] In this embodiment, when only the control switch M exists in the chip 1, if the atomizer is reversely connected to the battery rod, 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 forms a path through the body diode of the control switch M to achieve reverse conduction. When only the second switch M" exists in the chip 1, if the atomizer is reversely connected to the battery rod, the body diode of the second switch M" is in the cut-off state, which can prevent the atomizer from being damaged due to reverse conduction. Therefore, connecting the heating element L, the control switch M, and the second switch M" in series between the first input terminal m1 and the second input terminal m2 can prevent the problem of reverse conduction of the control switch M.

[0057] Among them, the working modes of the atomizers in the second and third embodiments are similar to those of the first embodiment. For simplicity, they will not be elaborated here.

[0058] Please refer to Figure 6, which is a schematic structural diagram of the 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 terminal m1, the switch path interface VDS of the package 12 is connected to the first input terminal m1, and the other end of the heating element L is connected to the ground interface GND of the package 12. In this embodiment, the communication interface SDA of the package 12 is connected to the first input terminal m1, and the capacitor C is connected to the power supply interface VDD of the package 12 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, the first path end of the control switch M is connected to the first input terminal m1, the second path end of the control switch M is connected to the second input terminal m2, and the control end of the control switch M is connected to the control end n1 of the drive control circuit 13.

[0059] In this embodiment, after the battery rod communicates successfully with the atomizer, the battery rod can heat the heating element L according to the heating parameters stored in the atomizer, so that the atomizer works in the first mode. In this embodiment, since the heating element L and the control switch M are connected in parallel, after the battery rod fails to communicate with the atomizer, only by the battery rod sending a PWM signal can the heating element L generate heat, so that the atomizer works in the second mode. In this embodiment, the heating element L and the control switch M are connected in parallel, and the battery rod can determine whether the battery rod and the atomizer are products from the same manufacturer by judging whether the battery rod can communicate successfully with the atomizer, so as to achieve the identification of the atomizer, but the function of prohibiting the use of the atomizer if the battery rod and the atomizer do not match cannot be realized.

[0060] The chip for the atomizer provided by the present invention can realize the series connection of the heating element and the control switch, and can also realize the parallel connection of the heating element and the control switch. Different functions can be realized according to different software settings, so as to meet the different usage requirements of the atomizer in different usage environments.

[0061] Please refer to Figure 7 , which is a schematic functional module diagram of an embodiment of the battery rod provided by the present invention. The battery rod is used to drive the atomizer inserted therein and supply power to the atomizer.

[0062] The battery rod includes: a drive chip 100 and a drive identification circuit 200 connected to the drive chip 100. When the atomizer is inserted into the battery rod, the drive chip 100 determines whether the atomizer is inserted correctly or reversely through the drive identification circuit 200, and controls the drive identification circuit 200 to work in the correct insertion mode or the reverse insertion mode.

[0063] Specifically, the drive recognition circuit 200 includes: a direction recognition unit 10, a drive unit 30, and a power supply switching unit 20; the drive chip 100 includes a detection communication port B, a drive port A, and a switching port C; the direction recognition unit 10 is connected to the detection communication port B, the drive unit 30 is connected to the drive port A, and the power supply switching unit 20 is connected to the switching port C; the direction recognition unit 10 and the power supply switching unit 20 are respectively electrically connected to the connection pin h; the drive unit 30 is directly electrically connected to the connection pin h (as shown by the dotted line L1 in the figure) or is electrically connected to the connection pin h through the power supply switching unit 20 (as shown by the dashed line L2 in the figure).

[0064] The drive chip 100 determines whether the atomizer is inserted correctly or in reverse through the detection communication port B and the direction recognition unit 10, and controls the power supply switching unit 20 to switch through the switching port C, so that the drive recognition circuit 200 operates in the correct insertion mode or the reverse insertion mode.

[0065] Specifically, please refer to Figure 8 , Figure 8 as Figure 7 a schematic diagram of the functional modules of a specific embodiment of, in which the detection communication port B includes a first detection communication port P1 and a second detection communication port P1'. The direction recognition unit 10 includes: a first recognition module 11 and a second recognition module 12. Among them, the first recognition module 11 is connected to the first detection communication port P1, and the second recognition module 12 is connected to the second detection communication port P1'. In an embodiment, when it is determined that the first detection communication port P1 can communicate with the atomizer, it is determined that the atomizer inserted into the battery rod is inserted correctly; when it is determined that the second detection communication port P1' can communicate with the atomizer, it is determined that the atomizer inserted into the battery rod is inserted in reverse. Specifically, when the atomizer is inserted into the battery rod, both the first detection communication port P1 and the second detection communication port P1' of the battery rod send a string of data to the atomizer. If the first detection communication port P1 detects a feedback signal, it means that the atomizer inserted into the battery rod is inserted correctly. If the second detection communication port P1' detects a feedback signal, it means that the atomizer inserted into the battery rod is inserted in reverse.

[0066] The connection pin h further includes: a first connection pin h1 and a second connection pin h2, which are used to form an electrical connection with the atomizer inserted into the battery rod. Taking the atomizer shown in the above embodiment as an example for illustration. Among them, when the atomizer inserted into the battery rod is inserted correctly, the drive recognition circuit 200 operates in the correct insertion mode so that the first connection pin h1 serves as the power connection pin, and the second connection pin h2 serves as the ground voltage connection pin. At this time, when the atomizer is inserted into the battery rod, the first connection pin h1 is connected to the first input terminal m1, and the second connection pin h2 is connected to the second input terminal m2.

[0067] When the atomizer inserted into the battery rod is reversely inserted, the driving recognition circuit 200 operates in the reverse insertion mode so that the first connection pin h1 serves as the ground voltage connection pin, and the second connection pin h2 serves as the power connection pin; at this time, when the atomizer is inserted into the battery rod, the first connection pin h1 is connected to the second input terminal m2, and the second connection pin h2 is connected to the first input terminal m1.

[0068] In another embodiment, the detection communication port B includes a first detection communication port P1 and a second detection communication port P1'. When it is determined that the resistance value collected by the first detection communication port P1 is within a first preset range and the resistance value collected by the second detection communication port P1' is within a second preset range, it is determined that the atomizer inserted into the battery rod is correctly inserted. When it is determined that the resistance value collected by the first detection communication port P1 is within the second preset range and the resistance value collected by the second detection communication port P1' is within the first preset range, it is determined that the atomizer inserted into the battery rod is reversely inserted.

[0069] As Figure 8 shown, in this embodiment, the driving port A includes a first group of driving ports P2 (P3) and a second group of driving ports P2' (P3'). The driving unit 30 includes a first driving module 31 and a second driving module 32. Among them, the first driving module 31 is connected to the first group of driving ports P2 (P3), and the second driving module 32 is connected to the second group of driving ports P2' (P3').

[0070] The power supply switching unit 20 includes a first switching module 21 and a second switching module 22. The switching port C includes a first switching port P0 and a second switching port P0'. The first switching module 21 is connected to the first switching port P0, the first driving module 31, and the first connection pin h1. The second switching module 22 is connected to the second switching port P0', the second driving module 32, and the second connection pin h2.

[0071] When the atomizer inserted into the battery rod is correctly inserted, the first switching port P0 and the second switching port P0' switch the first switching module 21 to the non-working mode and the second switching module 22 to the working mode, so that the first connection pin h1 is connected to the first driving module 31, and the second connection pin h2 is connected to the ground voltage. When the atomizer inserted into the battery rod is reversely inserted, the first switching port P0 and the second switching port P0' switch the first switching module 21 to the working mode and the second switching module 22 to the non-working mode, so that the first connection pin h1 is connected to the ground voltage, and the second connection pin h2 is connected to the second driving module 22.

The first end of the first resistor R1 is connected to the power supply voltage VDD, and the second end of the first resistor R1 is connected to the first detection communication port P1 and the first connection pin h1.

The first path end of the second switch T2 is connected to the second connection pin h2, the second path end of the second switch T2 is connected to the ground voltage, and the control end of the second switch T2 is connected to the second switching port P0'. When the atomizer with the battery rod inserted is inserted correctly, the first switching port P0 controls the first switch T1 to disconnect, and the second switching port P0' controls the second switch T2 to conduct, so that the second connection pin h2 is connected to the ground voltage. When the atomizer with the battery rod inserted is inserted reversely, the first switching port P0 controls the first switch T1 to conduct, so that the first connection pin h1 is connected to the ground voltage, and the second switching port P0' controls the second switch T2 to disconnect.

[0074] The first group of drive ports P2 (P3) includes a first positive drive port P2 and a second positive drive port P3.

The first end of the fourth resistor R4 is connected to the second path end of the sixth switch T6, and the second end of the fourth resistor R4 is connected to the second detection communication port P1’ and the second connection pin h2.

[0076] When the direction recognition circuit 10 recognizes that the atomizer is being inserted into the battery rod correctly, the third switch T3 and the fourth switch T4 are controlled to conduct through the first positive driving port P2 and the second positive driving port P3, thereby heating the heating element L. When the direction recognition circuit 10 recognizes that the atomizer is being inserted into the battery rod in reverse, the fifth switch T5 and the sixth switch T6 are controlled to conduct through the first reverse driving port P2’ and the second reverse driving port P3’, thereby heating the heating element L.

[0077] The battery rod shown in this embodiment can recognize whether the inserted atomizer is inserted correctly or in reverse, and select a corresponding driving method to drive the atomizer according to the recognition result, so that the atomizer can be driven by the battery rod and work whether it is inserted into the battery rod correctly or in reverse.

[0078] Please refer to Figure 10 , Figure 10 for Figure 7 a schematic diagram of the functional modules of another specific embodiment. In this embodiment, the driving unit 30 only includes one driving module. Specifically, please combine Figure 11 , Figure 11 for Figure 10 the specific structural diagram of the functional module described above. In this embodiment, the direction recognition circuit 10 is the same as that in the battery rod shown above Figure 9 and will not be elaborated here. The difference from the battery rod shown above Figure 9 is that:

[0079] When the atomizer inserted into the battery rod is inserted correctly, the first switching port P0 and the second switching port P0’ switch the power supply switching unit 20 to work in the first mode, so that the first connection pin h1 is connected to the output end N of the driving unit 30, while the second connection pin h2 is connected to the ground voltage GND.

[0080] When the atomizer inserted into the battery rod is reversely inserted, the first switching port P0 and the second switching port P0' switch the power supply switching unit 20 to work in the second mode, so that the first connection pin h1 is connected to the ground voltage GND, and the second connection pin h2 is connected to the output end N of the driving unit 30.

[0081] Specifically, in this embodiment, the power supply switching unit 20 includes: a first switching module 21 and a second switching module 22.

Among them, when the atomizer inserted into the battery rod is correctly inserted, the first switching port P0 switches the first switching module 31 to be connected to the output end N of the driving unit 30, and the second switching port P0' switches the second switching module 22 to be connected to the ground voltage GND. When the atomizer inserted into the battery rod is reversely inserted, the first switching port P0 switches the first switching module 31 to be connected to the ground voltage GND, and the second switching port P0' switches the second switching module 22 to be connected to the output end N of the driving unit 30.

[0082] Specifically, as Figure 11 shown, the first switching module 21 includes: a fifth resistor R5, a first capacitor C1, a first diode D1, a seventh switch T7, and an eighth switch T8. The first end of the fifth resistor R5 is connected to the output end N of the driving unit. The first end of the first capacitor C1 is connected to the output end N of the driving unit, and the second end of the first capacitor C1 is connected to the second end of the fifth resistor R5. The first end of the first diode D1 is connected to the second end of the fifth resistor R5, and the second end of the first diode D1 is connected to the first switching port P0. The first path end of the seventh switch T7 is connected to the output end N of the driving unit, the second path end of the seventh switch T7 is connected to the first connection pin h1, and the control end of the seventh switch T7 is connected to the second end of the fifth resistor R5. The first path end of the eighth switch T8 is connected to the first connection pin h1, the second path end of the eighth switch T8 is connected to the ground voltage GND, and its control end is connected to the first switching port P0.

[0083] Specifically, the second switching module 22 includes: a sixth resistor R6, a second capacitor C2, a second diode D2, a ninth switch T9, and a tenth switch T10. The first end of the sixth resistor R6 is connected to the output end N of the driving unit. The first end of the second capacitor C2 is connected to the output end N of the driving unit, and the second end of the second capacitor C2 is connected to the second end of the sixth resistor R6. The first end of the second diode D2 is connected to the second end of the sixth resistor R6, and the second end of the second diode D2 is connected to the second switching port P0'. The first path end of the ninth switch T9 is connected to the output end N of the driving unit, the second path end of the ninth switch T9 is connected to the second connection pin h2, and the control end of the ninth switch T9 is connected to the second end of the sixth resistor R6. The first path end of the tenth switch T10 is connected to the second connection pin h2, the second path end of the tenth switch T10 is connected to the ground voltage GND, and the control end of the tenth switch T10 is connected to the second switching port P0'.

[0084] In this embodiment, the driving port A includes a first driving port P2 and a second driving port P3. The driving unit 30 includes: an eleventh switch T11, a twelfth switch T12, and a seventh resistor R7. Among them, the first path end of the eleventh switch T11 is connected to the power supply voltage VDD, the second path end of the eleventh switch T11 is connected to the output end N of the driving unit, and the control end of the eleventh switch T11 is connected to the first driving port P2. The first path end of the twelfth switch T12 is connected to the power supply voltage VDD, and the control end of the twelfth switch T12 is connected to the second driving port P3. The first end of the seventh resistor R7 is connected to the second path end of the twelfth switch T12, and the second end of the seventh resistor R7 is connected to the output end N of the driving unit.

[0085] The direction recognition circuit 10 shown in this embodiment is Figure 9 the same as the direction recognition circuit 10 in the battery rod described above, and will not be elaborated here.

[0086] When 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, causing the seventh switch M7 to conduct, and the first connection pin h1 is connected to the output end N of the driving circuit; the second switching port P0' outputs a high-level signal, causing the tenth switch T10 to conduct, point B is grounded, and the second connection pin h2 is grounded.

[0087] When the direction recognition circuit 10 recognizes that the atomizer is being inserted into the battery rod in the reverse direction, the first switching port P0 outputs a high-level signal, causing the ninth switch M9 to conduct, and the second connection pin h2 is connected to the output end N of the driving circuit; the second switching port P0' outputs a low-level signal, causing the eighth switch T8 to conduct, point A is grounded, and the first connection pin h1 is grounded.

[0088] 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, the sixth resistor R6 in the second switching module 22 can ensure that the corresponding seventh switch T7 and ninth switch T9 can be quickly turned on when the eleventh switch T11 is turned on, and can ensure that the corresponding seventh switch T7 and ninth switch T9 can continuously maintain the on state when the eleventh switch T11 is turned off.

[0089] When the atomizer is inserted into the battery rod, when the PWM signal is output through the eleventh switch T11 to supply power to the heating element L, when the first drive port P2 is at a low level, the eleventh switch T11 is turned on (equivalent to the high level state of the PWM signal), and the source electrodes 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 will be clamped to a low level by the first diode D1 and the first switching port P0, thereby turning on the seventh switch T7. The first capacitor C1 will be charged to the voltage difference ΔV between the gate and the source of the seventh switch T7, and then the current will pass through the seventh switch T7 and be input to the first input terminal m1 of the atomizer, that is, the output terminal N of the drive circuit is input to the first input terminal m1 of the atomizer. When the first drive port P2 is at a high level, the eleventh switch T11 is turned off (equivalent to the low level state of the PWM signal), and the source electrode of the seventh switch T7 will be pulled down to a low voltage by the heating element L. However, since the first capacitor C1 has only the fifth resistor R5 as the discharge channel, the voltage across the first capacitor C1 will not drop quickly, so that the seventh switch T7 can be continuously turned on, that is, the output terminal N of the drive circuit is input to the first input terminal m1 of the atomizer, thereby ensuring that the twelfth switch T12 and the seventh resistor R7 channel can collect the parameters of the heating element L.

[0090] When the atomizer is inserted reversely into the battery rod, 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 (equivalent to the high-level state of the PWM signal), and the source electrodes 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 will be clamped to a low level by the second diode D2 and the second switching port P0', thereby turning on the ninth switch T9. The second capacitor C2 will be charged to the voltage difference ΔV between the gate and the source of the ninth switch T9, and then the current will pass through the ninth switch T9 and be input to the second input terminal m2 of the atomizer, that is, the output terminal N of the drive 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 (equivalent to the low-level state of the PWM signal), and the source electrode of the ninth switch T9 will be pulled down to a low voltage by the heating element L. However, since the second capacitor C2 only has the discharge channel of the sixth resistor R6, the voltage across the second capacitor C2 will not drop rapidly, so that the ninth switch T9 can be maintained in a conducting state, that is, the output terminal N of the drive 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 the parameters of the heating element L.

[0091] Please refer to Figure 12 , for Figure 3 the structural schematic diagram of the atomizer being inserted correctly Figure 9 into the battery rod as shown.

[0092] Specifically, set the second switch T2 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, and the first detection communication port P1 detects a jump signal, thereby waking up the drive chip MCU of the battery rod. At this time, the first detection communication port P1 and the second detection communication port P1' of the drive chip 100 of the battery rod respectively send a string of data to the atomizer through the first connection pin h1 and the second connection pin h2. If the first detection communication port P1 detects a feedback signal, it means that the atomizer is inserted correctly into the battery rod; if the second detection communication port P1' detects a feedback signal, it means that the atomizer is inserted reversely into the battery rod.

[0093] Specifically, in another embodiment, when it is determined that the resistance value collected by the first detection communication port P1 is within the first preset range, while the resistance value collected by the second detection communication port P1' is within the second preset range, it is determined that the atomizer inserted into the battery rod is inserted correctly. Otherwise, it is inserted reversely. That is, if the resistance value collected by the first detection communication port P1 is the internal resistance of the drive control circuit 13 (for example, greater than 3 kΩ), while the resistance value collected by the second detection communication port P1' is the resistance value of the heating element L (for example, less than 3 Ω), it indicates that the atomizer is correctly 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 (for example, less than 3 Ω), while the resistance value collected by the second detection communication port P1' is the internal resistance of the drive control circuit 13 (for example, greater than 3 kΩ), it indicates that the atomizer is reversely inserted into the battery rod.

[0094] This embodiment will be described by taking the correct insertion of the atomizer into the battery rod as an example. Specifically, the first connection pin h1 of the battery rod is connected to the first input end m1 of the atomizer, and the second connection pin h2 of the battery rod is connected to the second input end m2 of the atomizer. And in this embodiment, the first switching port P0 controls the first switch T1 to be turned off, and the second switching port P0' controls the second switch T2 to be turned on, so that the voltage at point B is grounded. At this time, the battery rod supplies the power voltage VDD to the first input end m1 of the atomizer through the first drive module 31, and then heats the heating element L.

[0095] Please refer to Figure 13 , which is Figure 3 the structural schematic diagram of the reverse insertion of the atomizer as shown in Figure 9 the battery rod shown.

[0096] 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. The second detection communication port P1' detects a jump signal, thereby waking up the drive chip MCU of the battery rod. At this time, the first detection communication port P1 and the second detection communication port P1' of the drive chip 100 of the battery rod respectively send a string of data to the atomizer through the first connection pin h1 and the second connection pin h2. If the first detection communication port P1 detects a feedback signal, it indicates that the atomizer is correctly inserted into the battery rod; if the second detection communication port P1' detects a feedback signal, it indicates that the atomizer is reversely inserted into the battery rod.

[0097] Specifically, in another embodiment, when it is determined that the resistance value collected by the first detection communication port P1 is within the first preset range, while the resistance value collected by the second detection communication port P1' is within the second preset range, it is determined that the atomizer inserted into the battery rod is inserted correctly. Otherwise, it is inserted incorrectly. That is, if the resistance value collected by the first detection communication port P1 is the internal resistance of the drive control circuit 13 (for example, greater than 3 kΩ), and the resistance value collected by the second detection communication port P1' is the resistance value of the heating element L (for example, less than 3 Ω), it indicates that the atomizer is correctly 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 (for example, less than 3 Ω), and the resistance value collected by the second detection communication port P1' is the internal resistance of the drive control circuit 13 (for example, greater than 3 kΩ), it indicates that the atomizer is inserted incorrectly into the battery rod.

[0098] This embodiment will be described by taking the correct insertion of the atomizer into the battery rod as an example. Specifically, the first connection pin h1 of the battery rod is connected to the second input terminal m2 of the atomizer, and the second connection pin h2 of the battery rod is connected to the first input terminal m1 of the atomizer. And in this embodiment, the first switching port P0 controls the first switch T1 to conduct, and the second switching port P0' controls the second switch T2 to disconnect, thereby making the voltage at point A grounded. At this time, the battery rod provides the power supply voltage VDD to the first input terminal m1 of the atomizer through the second drive module 32, and then heats the heating element L.

[0099] Figure 3 The specific working principle of the correctly inserted or incorrectly inserted atomizer shown Figure 11 in the battery rod shown can be seen in the above description, and will not be elaborated here.

[0100] Please refer to Figure 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 drive chip 100, a drive circuit 60, and an identification circuit 70. Among them, the drive circuit 60 can be Figure 9 the first drive module 31 shown, and the identification circuit 70 can be Figure 9 the first identification module 11 shown. For a detailed description, please refer to Figure 9 the description.

[0101] The atomizer is Figure 3 the atomizer shown. For a detailed description, please refer to Figure 3(Description. In this embodiment, the atomizer includes a chip 1. The chip 1 is used to communicate with the battery rod when the atomizer is inserted into the battery rod. Specifically, the chip 1 includes a communication port SDA, and the chip 1 can communicate with the battery rod through the communication port SDA. The atomizer further includes a capacitor C. The capacitor C is connected to the chip 1. When the atomizer is inserted into the battery rod, the capacitor C is charged according to the communication signal between the atomizer and the battery rod, so as to supply power to the chip by using the capacitor C, so that the chip can work properly.)

[0102] Specifically, please refer to Figure 15 , Figure 15 is Figure 14 a schematic flowchart of an embodiment of the usage method of the atomizer in

[0103] Step S11: When the atomizer is inserted into the battery rod, the atomizer communicates with the battery rod.)

[0104] Step S12: The capacitor in the atomizer is charged according to the communication signal between the atomizer and the battery rod, and then the capacitor is used to supply power to the atomizer, so that the atomizer can work properly.)

[0105] Specifically, the 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 and the resistor R in the atomizer are used for voltage division, a jump signal is generated at the detection communication port P1 of the battery rod, and 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 to supply power to the chip 1, so that the chip 1 can work properly.)

[0106] Specifically, the chip 1 includes a communication interface SDA and a power supply interface VDD. The power supply interface VDD is connected to the capacitor C. The communication interface SDA and the power supply interface VDD of the chip 1 are connected through internal lines. When the atomizer and the battery rod communicate, the capacitor C is charged through the communication interface SDA by means of the internal lines.)

[0107] In an embodiment, when the battery rod and the atomizer are working, the detection communication port P1 or the driving port P2 or P3 of the battery rod can send a communication signal to the atomizer. For example, the battery rod can use the BMC coding method to send the communication signal.)

[0108] When the atomizer receives a communication signal that is a data storage command and data storage, after the atomizer receives the communication signal, the capacitor C can receive the charging voltage provided by the battery rod within the first predetermined time period to be charged and store electric energy, so that the capacitor C can power the chip 1 with the stored electric energy, so that the chip 1 can normally complete the data storage and return the corresponding communication signal. For example, if the battery rod needs to update the current suction parameters in the atomizer, the communication signal received by the atomizer is the data storage command and the updated current suction parameters. The atomizer stores the updated current suction parameters according to the data storage command. At this time, during the data storage process, the capacitor C can receive the charging voltage provided by the battery rod within the first predetermined time period to be charged and store electric energy, so that the capacitor C can power the chip 1 with the stored electric energy, so that the chip 1 can be normally provided with electric energy during the data storage process, and return the corresponding communication signal after the data storage is completed.

[0109] When the chip 1 writes the stored data into the internal memory, a relatively large current, such as 5mA to 30mA, is required. At this time, the battery rod continues to provide high voltage and high current to the atomizer. After the chip 1 completes writing the stored data, the battery rod stops supplying power to the atomizer, so that the drive control circuit 13 can maintain a stable voltage when writing the stored data.

[0110] When the communication signal received by the atomizer is a normal command or a data reading command, after the atomizer receives the communication signal, the capacitor C can receive the charging voltage provided by the battery rod to be charged and store electric energy within the second predetermined time period, so that the capacitor C can power the chip 1 with the stored electric energy, so that the chip 1 performs the corresponding operation according to the communication signal and returns the corresponding communication signal. For example, if the communication signal received by the atomizer is to read the default puff parameter, then after the atomizer receives the reading of the default puff parameter, the capacitor C receives the charging voltage provided by the battery rod to be charged and store electric energy within the second predetermined time period of reading the default puff parameter, so that the capacitor C can power the chip 1 with the stored electric energy, so that the chip 1 performs the corresponding operation according to the communication signal and returns the corresponding communication signal.

[0111] 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, 4ms is the time required to save a single byte), and the second preset time period may be, for example, 1 ms (the time required for data verification and other processing).

[0112] In one embodiment, when the communication signal received by the atomizer is a data storage command and a storage data, the communication signal returned by the atomizer is a data write completion signal. For example, if the atomizer receives an update of the current puff parameter and an updated current puff parameter, the atomizer updates the current puff parameter and returns a data write completion signal to the battery rod.

[0113] When the communication signal received by the atomizer is a data reading command, the communication signal returned by the atomizer is the data signal to be read. For example, if the atomizer receives an instruction to read the default puff parameters, the atomizer returns the stored default puff parameters to the battery rod.

[0114] When the communication signal received by the atomizer is a common command, the communication signal returned by the atomizer is a common command, which is data or a command sent by the battery rod to the atomizer.

[0115] In one embodiment, when the atomizer 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 to be charged and store electric energy within the third preset time period, so that the capacitor C can power the chip 1 with the stored electric energy, so that the chip 1 can communicate with the battery rod normally. Specifically, the first logic level is a logic high level "1", that is, if the communication signal returned by the atomizer to the battery rod has a logic high level "1", the battery rod continues to provide a charging voltage to the capacitor C through the driving circuit 60 within the third preset time period so that the capacitor C is charged and stores electric energy. Specifically, in one embodiment, the third preset time period can be, for example, 10 to 30us, and the third preset time period is less than the duration of the communication signal being at the first logic level. It can be understood that the atomizer can communicate with the battery rod by using the BMC coding method. In the BMC coding method, a jump from a high level to a low level represents 1, and a jump from a low level to a high level represents 0. That is to say, the battery rod can communicate with the atomizer only by identifying the jump signal. Therefore, during the period when the atomizer transmits the high-level signal of the BMC code, the battery rod can charge the capacitor C through the driving circuit 60, and the charging of the capacitor C can be realized without hindering the communication between the two.

[0116] Specifically, the atomizer also includes a heating element L. The heating element L is connected to the chip 1. When the atomizer is inhaled, the atomizer receives a PWM signal of a preset frequency to heat the heating element L, wherein the preset frequency is 1KHz to 200KHz. In a preferred embodiment, the preset frequency is 20KHz. The capacitor C is charged when the PWM signal is at a first logic level. The capacitor C is discharged when the PWM signal is at a second logic level, and the maximum charging time of the capacitor C is less than the duration of the PWM signal at the first logic level, and the minimum discharge time of the capacitor C is greater than the duration of the PWM signal at the second logic level.

[0117] Specifically, the period of the conventional PWM signal of the electronic atomization device is 10 ms (100 Hz). When the resistance is very small / the power is very small / the voltage is very high, an extreme situation where the duty cycle is very small will occur. Under extreme conditions, the duty cycle is close to 14%, the high-level duration is 1.4 ms, and the low-level duration is 8.6 ms. The driving control circuit 13 of the atomizer and the capacitor C only have a charging time of 1.4 ms. When the supply voltage is low, there is a risk that the operating voltage of the driving control circuit 13 quickly drops to the limit low voltage, thus unable to maintain the normal operating state of the driving control circuit 13 to keep the control switch M in the atomizer conducting.

[0118] To address this problem, the frequency of the PWM signal can be increased in the above manner. In this way, even when the duty cycle is the same, due to the shortening of the heating cycle, the discharge time of the capacitor C of the driving control circuit 13 of the atomizer will also be shortened, thereby reducing the voltage fluctuation across the capacitor C and making the operating voltage of the driving control circuit 13 stable.

[0119] From the charging formula of the capacitor C, I*ΔT = ΔU*C = Q, it can be seen that where I is the current through which the battery rod charges the capacitor C via the PWM signal, ΔU is the voltage difference between the capacitor C charging from 1.8 V to the operating voltage of the heating element L, C is the capacitance of the capacitor C, and ΔT is the charging time of the capacitor C. Considering actual applications, when the current is the smallest and the charging voltage difference is the largest, the charging time is the longest. As long as this maximum charging time is less than the high-level time of the duty cycle, it can ensure that the capacitor is fully charged in each cycle. In the current product, the minimum discharge current I of the battery rod is 3 A, and ΔU corresponds to 1.9 V. Then ΔTmax = 0.63*C. When the capacitance C of the capacitor C takes a value of 1 uF, ΔTmax = 630 ns. When the frequency of the PWM signal corresponds to 200 KHz, even at the minimum duty cycle, ΔTmax is less than the logical high-level duration of the PWM signal, which can ensure that the capacitor C in the atomizer is fully charged.

[0120] Similarly, the discharge formula of the capacitor C can also be used where I is the current consumed by the driving control circuit 13, ΔU is the voltage difference when the voltage of the capacitor C discharges from the fully charged state to 1.8 V, C is the capacitance of the capacitor C, and ΔT is the discharge time of the capacitor C. Considering actual applications, when the consumed current I is the largest and the discharge voltage difference ΔU is the smallest, the discharge time is the shortest. As long as this shortest time is greater than the low-level time of the duty cycle, it can ensure the stable operation of chip 1. According to the maximum operating current of 50 uA of chip 1 and a discharge voltage difference of 0.3 V, then ΔTmin = 6000*C. When the capacitance C of the capacitor C takes a value of 1 uF, ΔTmin = 6 ms, and its discharge time is greater than the period of the PWM signal operating at 1 KHz, which can ensure the stable operation of chip 1.

[0121] Preferably, the predetermined frequency of the PWM signal is 20KHz, mainly considering that the ADC sampling of the communication port is relatively stable within 50us.

[0122] The atomizer shown in this embodiment can communicate with the battery rod by using the BMC coding method. Among them, the transition from high level to low level in the BMC coding method represents 1, and the transition from low level to high level represents 0. During the transmission of the high-level signal of the BMC coding, the battery rod charges the capacitor C of the atomizer through the drive circuit 60 to store electrical energy, so as to ensure the voltage stability of the chip 1 during communication. Specifically, when the chip 1 writes data into the internal memory, a relatively large current is required. At this time, the drive circuit 60 provides high voltage and large current for the chip 1 of the atomizer, which can further ensure the voltage stability of the chip 1 during communication. When the atomizer is puffed, the atomizer receives a PWM signal with a preset frequency to heat the heating element L, where the preset frequency is 1KHz to 200KHz. In a preferred embodiment, the preset frequency is 20KHz. This can ensure that the voltage remains stable during the heating of the heating element L.

[0123] Please refer to Figure 16 for Figure 14 a schematic flowchart of an embodiment of the usage method of the battery rod in Figure 14 . The battery rod is used to drive the atomizer inserted therein and supply power to the atomizer. Combining Figure 14 , the battery rod includes: a drive chip 100 and a drive circuit 60, and the drive circuit 60 is connected to the drive chip 100. The drive chip 100 communicates with the atomizer inserted therein through the drive circuit 60 and charges the capacitor C in the atomizer according to the communication signal between the atomizer and the battery rod to enable the atomizer to work normally.

[0124] Specifically, it includes:

[0125] Step S21: When the atomizer is inserted into the battery rod, the battery rod communicates with the atomizer.

[0126] 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 drive chip 100 further includes a detection communication port P1. The battery rod includes: an identification circuit 70 and a drive circuit 60. The identification circuit 70 is connected to the detection communication port P1 and the drive circuit 60. When the atomizer is inserted into the battery rod, the battery rod sends a communication signal to the atomizer through the detection communication port P1 or the drive ports P2, P3.

[0127] Step S22: Charge the atomizer according to the communication signal to enable the atomizer to work normally.

[0128] Specifically, when the communication signal is a data storage command and stored data, 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 after the atomizer normally completes the storage of the data, it receives the corresponding returned communication signal.

[0129] For example, if the communication signal sent by the battery rod is a command to update the current suction parameter in the atomizer, and the stored data is the updated current suction parameter, the atomizer stores the updated current suction 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 electrical energy, so that the capacitor C can supply power to the chip 1 by means of the stored electrical energy, so that the chip 1 can be normally supplied with electrical energy during the data storage process, and returns the corresponding communication signal after the data storage is completed.

[0130] Among them, when the chip 1 writes the stored data into the internal memory, a relatively large current is required, such as 5 mA to 30 mA. At this time, 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 drive control circuit 13 can maintain a stable voltage when writing the stored data.

[0131] When the communication signal is a general command or a data reading command, the battery rod provides a charging voltage to the atomizer within a second predetermined time period to charge the capacitor C of the atomizer, and after the atomizer executes the corresponding operation according to the communication signal and completes it, it receives the corresponding returned communication signal.

[0132] For example, if the communication signal sent by the battery rod is to read the default suction parameter, then after the atomizer receives the command to read the default suction parameter, the battery rod provides a charging voltage to the capacitor C within the second predetermined time period for reading the default suction parameter so that the capacitor C is charged and stores electrical energy, so that the capacitor C can supply power to the chip 1 by means of the stored electrical energy, so that the chip 1 executes the corresponding operation according to the communication signal and returns the corresponding communication signal.

[0133] Among them, the first preset time period is greater than the second preset time period. The first preset time period can be, for example, 4*x ms (x is the number of bytes to be saved, and 4 mS is the time required for single-byte saving), and the second predetermined time is, for example, 1 ms (the time required for data verification and other processing).

[0134] In one embodiment, when the communication signal sent by the battery rod is a data storage command and stored data, the communication signal returned by the atomizer is a data write completion signal. For example, if the communication signal sent by the battery rod is to update the current suction parameter and the updated current suction parameter, after the atomizer updates the current suction parameter, the battery rod receives the returned data write completion signal.

[0135] When the communication signal sent by the battery rod is a data read command, the returned response communication signal received by the battery rod is the data signal to be read. For example, if the communication signal sent by the battery rod is an instruction to read the default suction parameter, the returned response communication signal received by the battery rod is the default suction parameter.

[0136] When the communication signal sent by the battery rod is a general command, the returned response communication signal received by the battery rod is the general command. This general command is the data or command sent by the battery rod to the atomizer.

[0137] In one embodiment, when the battery rod receives the corresponding communication signal, when the communication signal is at the first logic level, the battery rod provides a charging voltage to the atomizer within a third preset time period to charge the capacitor of the atomizer. Specifically, the first logic level is the logic high level "1", that is, if the communication signal received by the battery rod has the logic high level "1", the battery rod continuously provides a charging voltage to the capacitor C through the drive circuit 60 within the third preset time period to charge and store electrical energy in the capacitor C. Specifically, in one embodiment, the third preset time period can be, for example: 10 - 30 us, and the third preset time period is less than the duration of the communication signal at the first logic level.

[0138] In one embodiment, when it is detected that the atomizer is being puffed, the battery rod sends a PWM signal with a preset frequency to heat the heating element of the atomizer, where the preset frequency is 1 KHz - 200 KHz. In a preferred embodiment, the preset frequency is 20 KHz. The capacitor C is charged when the PWM signal is at the first logic level. The capacitor C discharges when the PWM signal is at the second logic level, and the maximum charging time of the capacitor C is less than the duration of the PWM signal at the first logic level, and the minimum discharge time of the capacitor C is greater than the duration of the PWM signal at the second logic level.

[0139] Specifically, the period of the conventional PWM signal of the electronic atomization device is 10 ms (100 Hz). When the resistance is very small / the power is very small / the voltage is very high, an extreme situation where the duty cycle is very small will occur. Under extreme conditions, the duty cycle is close to 14%, the high-level duration is 1.4 ms, and the low-level duration is 8.6 ms. The driving control circuit 13 of the atomizer and the capacitor C only have 1.4 ms for charging. When the supply voltage is low, there is a risk that the working voltage of the driving control circuit 13 will quickly drop to the extreme low voltage, thus unable to maintain the normal working state of the driving control circuit 13 to keep the control switch M in the atomizer conducting.

[0140] To address this problem, the frequency of the PWM signal can be increased in the above manner. In this way, even when the duty cycle is the same, due to the shortened heating cycle, the discharge time of the capacitor C in the driving control circuit 13 of the atomizer will also be shortened, thereby reducing the voltage fluctuation across the capacitor C and making the working voltage of the driving control circuit 13 stable.

[0141] From the charging formula of the capacitor C, I * ΔT = ΔU * C = Q, it can be seen that where I is the current through which the battery rod charges the capacitor C via the PWM signal, ΔU is the differential voltage of the capacitor C charging from 1.8 V to the working voltage of the heating element L, C is the capacitance of the capacitor C, and ΔT is the charging time of the capacitor C. Considering practical applications, when the current is the smallest and the charging voltage difference is the largest, the charging time is the longest. As long as this maximum charging time is less than the high-level time of the duty cycle, it can ensure that the capacitor is fully charged in each cycle. In the current product, the minimum discharge current I of the battery rod is 3 A, and ΔU corresponds to 1.9 V, then ΔTmax = 0.63 * C. When the capacitance C of the capacitor C takes a value of 1 μF, ΔTmax = 630 ns. When the PWM signal frequency corresponds to 200 KHz, even at the minimum duty cycle, ΔTmax is less than the logical high-level duration of the PWM signal, which can ensure that the capacitor C in the atomizer is fully charged.

[0142] Similarly, the discharge formula of the capacitor C can also be used where I is the current consumed by the driving control circuit 13, ΔU is the voltage difference when the voltage of the capacitor C discharges from the fully charged state to 1.8 V, C is the capacitance of the capacitor C, and ΔT is the discharge time of the capacitor C. Considering practical applications, when the consumed current I is the largest and the discharge voltage difference ΔU is the smallest, the discharge time is the shortest. As long as this shortest time is greater than the low-level time of the duty cycle, it can ensure the stable operation of chip 1. According to the maximum working current of 50 μA of chip 1 and a discharge voltage difference of 0.3 V, then ΔTmin = 6000 * C. When the capacitance C of the capacitor C takes a value of 1 μF, ΔTmin = 6 ms, and its discharge time is greater than the period of the PWM signal working at 1 KHz, which can ensure the stable operation of chip 1.

[0143] Preferably, the predetermined frequency of the PWM signal is 20KHz, mainly considering that the ADC sampling of the communication port is relatively stable within 50us.

[0144] The atomizer shown in this embodiment can communicate with the battery rod using the BMC coding method. During the transmission of the high-level signal, the battery rod charges the capacitor C of the atomizer through the drive circuit 60 to store electrical energy, thereby ensuring the voltage stability of the chip 1 during communication. Specifically, when the chip 1 writes data into the internal memory, a relatively large current is required. At this time, the drive circuit 60 provides a high voltage and a large current for the chip 1 of the atomizer, which can further ensure the voltage stability of the chip 1 during communication. When the atomizer is puffed, the atomizer receives a PWM signal with a preset frequency to heat the heating element L, where the preset frequency is 1KHz to 200KHz. In a preferred embodiment, the preset frequency is 20KHZ. This can ensure that the voltage remains stable during the heating of the heating element L.

[0145] In the electronic atomization device provided by the present invention, a drive chip and a drive identification circuit are provided in the battery rod, and the drive identification circuit is connected to the drive chip. When the atomizer is inserted into the battery rod, the drive chip determines whether the atomizer is inserted correctly or reversely through the drive identification circuit, and controls the drive identification circuit to work in the correct-insertion mode or the reverse-insertion mode. In this way, it can be ensured that the battery rod and the atomizer can work normally in both the correct-insertion or reverse-insertion mode.

[0146] The electronic atomization device provided by the present invention can charge the capacitor in the atomizer through the battery rod so that the capacitor supplies power to the chip of the atomizer, thereby ensuring the voltage stability of the chip of the atomizer.
