detailed description

Embodiments of the present invention provide a battery assembly, an atomizing assembly, an electronic cigarette, and a method for preventing oil-free smoking, which can avoid burning cotton.

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

Please refer to FIG. 1 . FIG. 1 is a schematic structural diagram of an embodiment of the electronic cigarette of the present invention. In this embodiment, the electronic cigarette includes a battery assembly 1 and an atomizing assembly 2 .

The atomization assembly 2 includes an atomizer 21 for atomizing smoke liquid, and the atomization assembly 2 carries an identification code, and the identification code is for the battery assembly 1 to obtain the total usage time of the atomizer 21 and /or the information needed for the total number of times used. The battery assembly 1 is used to supply power to the atomizer 21 so that the atomizer 21 can atomize the smoke liquid to generate smoke.

Please refer to FIG. 2 . FIG. 2 is a schematic structural diagram of the battery assembly in the electronic cigarette shown in FIG. 1 . The battery assembly 1 includes a smoking detection module 11 , a control module 12 , an identification code identification module 13 and a battery 14 .

The smoking detection module 11 is used for detecting smoking signals. In this embodiment, when the smoking detection module 11 detects a smoking signal, the control module 12 controls the battery 14 to supply power to the atomizer 21 to start the atomizer 21 so that the atomizer The atomizer 21 can atomize the smoke liquid to generate smoke. In practical applications, the control module 12 may also control the battery 14 to supply power to the atomizer 21 only when other conditions are detected, which is not limited here.

After the atomizer 21 is started, the smoking detection module 11 is also used to detect the use time and/or the number of times after each start of the atomizer 21, wherein the number of uses of the atomizer refers to is the number of puffs the user has smoked.

The identification code identification module 13 is used to identify the identification code carried by the atomization assembly 2 when the smoking detection module 11 detects a smoking signal.

The control module 12 is used to obtain the identification code identified by the identification code identification module 13 according to the The total use time and/or the total number of times of use of the atomizer 21. For the convenience of description, the identification code identified by the identification code identification module is referred to as the first identification code for short below.

The control module 12 is further configured to detect that the difference between the total use time of the atomizer 21 and the cumulative value of the use time of the atomizer 21 is not greater than a first preset value, and/or the atomizer When the difference between the total number of times of use of the atomizer 21 and the cumulative value of the number of times of use of the atomizer 21 is not greater than a second preset value, the battery 14 is controlled to stop supplying power to the atomizer. Wherein, the first preset value and the second preset value are respectively greater than or equal to zero.

Specifically, for example, the control module 12 obtains according to the first identification code that the total usage time of the atomizer 21 is 100 minutes, and when the cumulative usage time of the atomizer 21 reaches 95 minutes, the control module 12 controls the battery 14 to stop Power the atomizer 21.

In this embodiment, there are many methods for the control module 12 to acquire the accumulated value of the usage time and/or usage times of the atomizer 21 . For example, a counter (not shown) is provided in the electronic cigarette for accumulating the use time and/or the number of times of use of the atomizer detected by the smoking detection module after each startup; The control module 12 obtains the usage duration and/or the accumulated value of the usage times of the atomizer 21 from the counter. Of course, the above is only an example and not a limitation.

It should be noted that the control module described herein controls the battery to stop supplying power to the atomizer 21, which includes two meanings:

The first is that when the smoking detection module 11 detects a smoking signal, the control module 12 first judges the relationship between the total use time of the atomizer 21 and the atomizer 21 before controlling the battery 14 to supply power to the atomizer 21. The difference between the cumulative value of the use time and/or the difference between the total number of times of use of the atomizer 21 and the cumulative value of the number of times of use of the atomizer 21, when the former is not greater than the first preset value and/or the latter is not greater than When the second preset value is reached, the control module 12 controls the battery 14 not to supply power to the atomizer 21 , that is, the atomizer 21 is no longer activated, and the battery 14 is controlled to stop supplying power to the atomizer 21 .

The second is that after the atomizer 21 is started, the control module 12 detects in real time whether the difference between the total use time of the atomizer 21 and the accumulated value of the use time of the atomizer 21 is not greater than the first preset value and /or whether the difference between the total number of times of use of the atomizer 21 and the cumulative value of the number of times of use of the atomizer 21 is not greater than the second preset value, if so, the control module 12 controls the battery 14 to stop being the atomizer 21 Power on, that is, turn off the atomizer 21 .

In this embodiment, since the atomization assembly carries the identification code, the battery assembly and the atomization assembly are electrically connected When connected, the battery pack can obtain the total usage time and/or total number of times of use of the atomizer according to the identification code recognized by the identification code identification module in the battery pack, and detect each start-up of the atomizer through the smoking detection module In this way, the control module in the battery pack can detect that the use time of the atomizer has accumulated up to the total use time of the atomizer and/or the When the cumulative number of times of use reaches or approaches the total number of times of use of the atomizer, the battery is controlled to stop supplying power to the atomizer, which avoids the situation that the smoke oil in the atomizer continues to work after being used up, and improves the efficiency of the atomizer. User experience.

In this embodiment, there are multiple ways for the atomization component 2 to carry the identification code. For example, the identification code is attached to the area opposite to the battery assembly 1 on the atomization assembly 2 by pasting, printing or other means, and the identification code identification module in the battery assembly 1 is arranged in the battery assembly opposite to this area , so that the identification code identification module 13 can identify the identification code. For another example, a second memory (not shown) is also provided in the atomizer 21, and the identification code is stored in the second memory, and the identification code identification module in the battery pack reads the identification code from the second memory, to identify the ID.

In this embodiment, there are multiple identification codes and identification code identification modules. Specifically, for example, the identification code is an image attached to the atomization component. Correspondingly, the identification code recognition module includes an image sensor and an image analysis processor; the image sensor is used to image the identification code on the atomization component, and the image analysis processor is used to read the image formed by the image sensor and analyze the The imaging is analyzed and identified. Among them, there are many ways for the image sensor to image the identification code, such as scanning imaging, imaging by photosensitive imaging, ultrasonic imaging (that is, the image sensor irradiates the identification code through ultrasonic waves, and the reflected ultrasonic waves enter the image sensor for imaging), radiation imaging, Magnetic induction imaging or conductive sensor imaging (that is, the image sensor is a capacitive sensor, and the capacitive sensor causes a change in the capacitance of the capacitive sensor to form an image by touching or approaching the identification code).

A specific example of one of scanning imaging will be described below. The identification code on the atomization component is coated with infrared-sensitive paint. When the image sensor emits infrared light to illuminate the identification code, the coating on the identification code will reflect the infrared light. The image analysis processor detects the reflected light to realize the identification. code identification.

In this embodiment, the smoking detection module 11 detects smoking signals in various ways. Specifically, for example, the smoking detection module 11 specifically includes a switch button (not shown in the figure), and when it is detected that the switch button is pressed, the smoking detection module 11 determines that a smoking signal is detected. For another example, the smoking detection module 11 specifically includes a microphone (also called an airflow sensor). When a user smokes an e-cigarette, the smoke in the e-cigarette There is air flowing through it. The microphone is used to detect the air pressure of the smoke channel in the electronic cigarette. When it is detected that the air pressure is less than a preset value, the smoking detection module 11 determines that a smoking signal is detected.

Of course, the smoking detection module 11 can also detect the smoking signal in other ways, which is not limited here.

In this embodiment, the control module 12 has multiple ways to obtain the total usage time and/or total usage times of the atomizer according to the first identification code. For example, as shown in FIG. 3 , FIG. 3 is a schematic structural diagram of another embodiment of the battery assembly in the electronic cigarette of the present invention. The battery pack 1 further includes a first memory 15, wherein the first memory 15 stores a plurality of identification codes, and each identification code corresponds to the total duration of use and/or the total number of times of use.

When the control module 12 obtains the first identification code, it searches the first memory 15 for an identification code identical to the first identification code. When the control module 12 finds the same identification code as the first identification code in the first memory 15 , the control module 12 acquires the total usage time and/or total usage times corresponding to the identification code in the first memory 15 . The control module 12 compares or subtracts the acquired total usage time with the accumulated usage duration of the atomizer 21 , and/or compares the acquired total usage times with the accumulated usage times of the atomizer 21 Compare or subtract.

When the control module 12 cannot find the same identification code as the first identification code in the first memory 15, the control module 12 can control the battery 14 to supply power to the atomizer 21, so that the atomizer 21 starts to atomize the e-liquid to Produces smoke. Or, preferably, when the control module 12 cannot find the same identification code as the first identification code in the first memory 15, the control module does not control the battery 14 to supply power to the atomizer 21, so that the atomizer 21 is not correct. The smoke liquid is atomized. In this way, the battery assembly 1 can only be combined with a specific atomizing assembly to form an electronic cigarette.

Preferably, in this embodiment, the control module is further configured to store the total usage time and/or total usage times of the atomizer acquired by the identification code identification module into the first memory, so that When the control module obtains the cumulative value of the use time and/or the cumulative value of the use times of the atomizer 21, the control module fetches the total use time and/or the total number of uses of the atomizer from the first memory and the atomizer The cumulative value of the use time and/or the cumulative value of the number of times of use of the converter 21 is compared or subtracted.

Preferably, in this embodiment, before the control module stores the total use time and/or total number of times of use of the atomizer obtained from the identification code by the identification code identification module into the first memory, the control The module is also used to detect the total usage time of the atomizer identified by the identification code identification module Whether the format of the length and/or the total number of times of use conforms to the preset format, and if yes, the total time of use of the atomizer and/or the total number of times of use are stored in the first memory. If not, the total duration of use and/or the total number of times of use will not be stored, and the atomizer will not be activated, which means that the atomization component is considered illegal.

Alternatively, the identification code carried by the atomization component 2 includes a storage integrated circuit or a wireless module, and the storage integrated circuit stores the total use time and/or the total number of times of use of the atomizer; and the identification code identification module 13 can specifically communicate with The storage integrated circuit or wireless module communication module, the identification code identification module 13 communicates with the storage integrated circuit or wireless module to obtain the total use time and/or the total number of times of use of the atomizer. Of course, the identification code carried by the atomization assembly 2 can also be other identification codes, and the identification code identification module 13 can also be other identification codes. block, there is no limit here.

In the present invention, preferably, the battery assembly is further provided with a reminder module, which is used to send a reminder signal when the control module controls the battery to stop supplying power to the atomizer. In this way, the user can be reminded that the e-liquid in the atomizer is exhausted, rather than that there is a problem with the battery component, so that the user can replace the atomizer and improve the user experience. Specifically, the prompting module may be a light emitting diode arranged on the surface of the battery assembly, and the prompting module sends out a prompting signal by lighting a light. Alternatively, the prompting module may be a voice module, which sends out a prompting signal by broadcasting voice. Of course, the above is only an example and not a limitation.

In the present invention, preferably, the battery assembly also carries a battery identification code, which is used to uniquely identify the battery assembly. When the smoking detection module detects a smoking signal, the control module is also used to detect whether there is a battery identification code in the atomization assembly, if not, store the battery identification code of the battery assembly in In the second storage of the atomization assembly. In this way, after the atomization component and the battery pack component form the electronic cigarette, when the battery component supplies power to the atomization component for the first time, the battery identification code of the battery pack component will be stored in the second memory in the atomization component.

If there is, the control module is also used to detect whether the battery identification code in the second memory of the atomization assembly is consistent with the battery identification code of the battery assembly, and if they are consistent, control the battery to be the battery identification code of the battery assembly. The power supply of the atomizer, if inconsistent, control the battery to stop supplying power to the atomizer. This way, different battery packs are prevented from powering the same atomizer pack. Since the use time and/or the cumulative value of the use times of the atomizer are stored in the battery component, avoiding different battery components to supply power to the atomization component can prevent the use time and/or the cumulative value of the use times of the atomizer from being different from the actual value.

In the above embodiment, the control module in the battery assembly detects whether the battery identification code stored in the atomization assembly is consistent with the battery identification code of the battery assembly. In practical applications, it is also possible for the atomization component to detect whether the battery identification code stored in the battery component is consistent with the battery identification code of the battery component.

Specifically, in this embodiment, the atomization assembly further includes a processing unit, configured to detect whether a battery identification code is stored in the second memory,

If not, the processing unit obtains and stores the battery identification code of the battery assembly when the battery assembly supplies power to the atomizer;

If there is, the processing unit acquires the battery identification code of the battery assembly when it is electrically connected to the battery assembly, and detects whether the battery identification code is the same as the battery identification code in the second memory If yes, maintain the electrical connection between the atomizer and the battery assembly, and if not, disconnect the electrical connection between the atomizer and the battery assembly.

In this embodiment, the second memory in the atomization component is an external memory. In practical applications, a single-chip microcomputer with its own non-volatile memory can also be used instead of the combination of the processing unit and the second memory.

Please refer to FIG. 6 . FIG. 6 is a schematic circuit diagram of an embodiment of the electronic cigarette of the present invention. As shown in FIG. 6 , the circuit structure of the electronic cigarette shown in this embodiment includes the circuit structure of the battery assembly and the circuit structure of the atomization assembly. Wherein, the circuit structure of the battery assembly is the same as the circuit structure of the battery assembly shown in Figure 4, the difference is that the circuit structure of the atomization assembly in this embodiment specifically includes: a single-chip microcomputer U3, a second capacitor C2, and an eighth resistor R8 , the ninth resistor R9, the second field effect transistor Q2, and the second diode D2. Wherein, the ninth resistor R9 is a resistance wire in the atomizer.

In this embodiment, the single-chip microcomputer U3 is a single-chip microcomputer with an EEPROM non-volatile memory, for example implemented by a chip PIC12F519. Of course, the single chip microcomputer can also use other chips, which are not limited in this embodiment.

The "1" pin of the microcontroller U3 is connected to the cathode of the second diode D2, and the anode of the second diode D2 is connected to the first interface J1 of the battery pack.

The "8" pin of the microcontroller U3 is grounded and connected to the "1" pin through the second capacitor C2.

The "2" pin of the single-chip microcomputer U3 is connected with the "8" pin of the microprocessor U1 in the battery pack, and the "5" pin is simultaneously connected with one end of the eighth resistor R8 and the gate of the second field effect transistor Q2 The other end of the eighth resistor R8 and the source of the second field effect transistor Q2 are simultaneously connected to the second interface J2 of the battery assembly and grounded. The drain of the second field effect transistor Q2 is connected to one end of the ninth resistor R9, and the other end of the ninth resistor R9 is connected to the anode of the second diode D2.

In this embodiment, the single-chip microcomputer U3 stores an identification code, and the single-chip microcomputer U3 is also used to store the battery identification code. When the atomization assembly has not been used, the battery identification code stored in the single chip microcomputer U3 is empty. When the battery pack activates the atomizer, the single-chip microcomputer U3 gets power and starts to work. When the single-chip microcomputer U3 detects that the internal battery identification code is empty, the "5" pin outputs a low level, and the second field effect transistor Q2 is disconnected, so that the ninth resistor R9 cannot be turned on, and thus the liquid cannot be atomized. At the same time, the single-chip microcomputer U3 reads the battery identification code from the memory E1 in the battery pack. When it is detected that the battery identification code conforms to the preset format, the battery identification code is stored in the single-chip microcomputer U3, and the "5" pin output high level, To turn on the second field effect transistor Q2, and then turn on the ninth resistor R9, so that the atomizer can atomize the smoke liquid.

If the battery identification code read by the single-chip microcomputer U3 does not conform to the preset format, it means that the battery pack is illegal, then the single-chip microcomputer U3 is still outputting a low level at the "5" pin, so that the ninth resistor R9 cannot be turned on , so that the smoke liquid cannot be atomized.

At this time, the battery identification code has been stored in the single-chip microcomputer U3. Every time the battery pack activates the atomizer so that the single-chip microcomputer U3 gets power to start working, the single-chip microcomputer U3 reads the battery identification code from the memory E1 in the battery pack, and detects the battery identification code and the battery stored in the single-chip microcomputer U3. Whether the identification codes are consistent, if they are the same, output a high level at the "5" pin to turn on the second field effect transistor Q2, if not, output a low level at the "5" pin, This makes the ninth resistor R9 incapable of conduction, thereby making it impossible to atomize the e-liquid.

Since the use time and/or the accumulated value of the use times of the atomization component are stored in the battery component, the atomization component in this embodiment can only be electrically connected to one battery component to form an electronic cigarette, which avoids the use of the atomization component and/or Misjudgment of battery components caused by wrong accumulative times of use, resulting in burning cotton.

In this embodiment, in the production process of electronic cigarettes, if it is necessary to test different atomization components, a general identification code can be set in the atomization components. When the battery identification code in the battery component is the general identification code At this time, the atomization component can directly output a high level at the "5" pin to turn on the second field effect transistor Q2.

In practical applications, it is also possible to store the cumulative value of the use time and/or the number of times of use of the atomizer in the memory of the atomization component, and the control module in the battery component only needs to read the accumulated value from the memory of the atomization component In this way, different battery components can be used to power the same atomizing component, so as to avoid the situation that the atomizing component cannot be combined with other battery components to form an electronic cigarette when the battery component fails in the electronic cigarette.

The electronic cigarette in the present invention has been explained above, and the method for preventing oil-free smoking of the present invention will be described below.

As shown in FIG. 7 , FIG. 7 is a flowchart of an embodiment of the method for preventing oil-free smoking according to the present invention. This example includes:

101. When the battery component in the electronic cigarette detects a smoking signal, the battery component identifies the identification code carried on the atomization component in the electronic cigarette.

In this embodiment, the electronic cigarette includes a battery component and an atomizing component, wherein the atomizing component carries an identification code, and the atomizing component includes an atomizer for atomizing e-liquid. The battery assembly is used to supply power to the atomizer, so that the atomizer atomizes e-liquid to generate smoke for the user to inhale.

There are many ways for the smoking detection module to detect smoking signals. Specifically, for example, the smoking detection module specifically includes a switch button (not shown in the figure), and when it is detected that the switch button is pressed, the smoking detection module determines that a smoking signal is detected. For another example, the smoking detection module specifically includes a microphone. When the user smokes the electronic cigarette, the smoke channel in the electronic cigarette has airflow flowing through it. The microphone is used to detect the air pressure of the smoke channel in the electronic cigarette. When the detected air pressure is lower than the preset value, the smoking detection module determines that a smoking signal is detected.

Of course, the smoking detection module can also detect the smoking signal in other ways, which is not limited here.

In this embodiment, there are multiple ways for the atomization component to carry the identification code. For example, the identification code is attached to the area of the atomization assembly opposite to the battery assembly by pasting, printing or other means, and the identification code identification module in the battery assembly is arranged in the battery assembly opposite to this area, so that The identification code identification module can identify the identification code. For another example, a memory is also provided in the atomizer, and the identification code is stored in the memory, and the identification code identification module in the battery pack reads the identification code from the memory to identify the identification code.

There are many ways for the battery component to identify the identification code carried on the atomization component. For example, the battery assembly includes an identification code identification module, and the identification code on the atomization assembly is identified through the identification code identification module. Among them, there are many kinds of identification codes and identification code identification modules. Specifically, for example, the identification code is an image attached to the atomization component. Correspondingly, the identification code recognition module includes an image sensor and an image analysis processor; the image sensor is used to image the identification code on the atomization component, and the image analysis processor is used to read the image formed by the image sensor and analyze the The imaging is analyzed and identified. Among them, there are many ways for the image sensor to image the identification code, such as scanning imaging, imaging by photosensitive imaging, ultrasonic imaging (that is, the image sensor irradiates the identification code through ultrasonic waves, and the reflected ultrasonic waves enter the image sensor for imaging), radiation imaging, Magnetic induction imaging or conductive sensor imaging (that is, the image sensor is a capacitive sensor, and the capacitive sensor causes a change in the capacitance of the capacitive sensor to form an image by touching or approaching the identification code).

A specific example of one of scanning imaging will be described below. The identification code on the atomizer assembly is painted with For coatings sensitive to infrared rays, when the image sensor emits infrared light to irradiate the identification code, the coating on the identification code will reflect infrared light, and the image analysis processor will detect the reflected light to realize the identification of the identification code.

102. The battery assembly obtains the total usage time and/or total usage times of the atomizer according to the recognized identification code.

In this embodiment, there are multiple ways for the battery assembly to acquire the total usage time and/or total usage times of the atomizer according to the identified identification code (hereinafter referred to as the first identification code for short).

Specifically, for example, a first memory is provided in the battery assembly, and the first memory stores a plurality of identification codes, and each identification code corresponds to the total duration of use and/or the total number of times of use.

When the battery pack obtains the first identification code, it searches for the same identification code as the first identification code in the first memory. When the battery pack finds the same identification code as the first identification code in the first memory, the battery pack acquires the total usage time and/or total number of usage times corresponding to the identification code in the first memory. When the battery assembly cannot find the same identification code as the first identification code in the first memory, the battery assembly can supply power to the atomizer, so that the atomizer starts to atomize the smoke liquid to generate smoke. Or, preferably, when the battery assembly cannot find the same identification code as the first identification code in the first memory, the battery assembly does not supply power to the atomizer, so that the atomizer does not atomize the smoke liquid. In this way, the battery component can only be combined with a specific atomizing component to form an electronic cigarette.

Alternatively, the identification code carried by the atomization component contains the total use time and/or the total number of times of use of the atomizer, and the battery component is specifically used to obtain the total use time and/or the total number of times of use of the atomizer from the identification code. total number of uses.

For example, the identification code carried by the atomization component is a two-dimensional code, and the battery component specifically includes a two-dimensional code identification module, and the total usage time and/or or the total number of uses. Alternatively, the identification code carried by the atomization assembly includes a storage integrated circuit or a wireless module, and the storage integrated circuit stores the total use time and/or the total number of times of use of the atomizer; and the battery assembly specifically includes The integrated circuit or the wireless module communicates with the storage integrated circuit or the wireless module to obtain the total usage time and/or total usage times of the atomizer. Certainly, the identification code carried by the atomization assembly may also be other identification codes, and the battery assembly may obtain the total usage time and/or total number of usage times of the atomizer from the identification code in other ways, which is not limited here.

103. The battery component obtains the cumulative number of the usage time and/or usage times of the atomizer value, when it is detected that the difference between the total use time of the atomizer and the accumulated value of the use time of the atomizer is not greater than the first preset value, and/or the total number of times of use of the atomizer and the When the difference between the cumulative values of the number of times of use of the atomizer is not greater than a second preset value, the battery assembly stops supplying power to the atomizer.

In this embodiment, there are multiple methods for the battery assembly to obtain the cumulative value of the usage time and/or usage times of the atomizer. For example, a counter (not shown) is provided in the electronic cigarette for accumulating the use time and/or the number of times of use of the atomizer detected by the smoking detection module after each startup; The battery assembly obtains the usage duration and/or the cumulative value of usage times of the atomizer from the counter. Of course, the above is only an example and not a limitation.

It should be noted that the control module described herein controls the battery to stop supplying power to the atomizer 21, which includes two meanings:

The first is that when the smoking detection module 11 detects a smoking signal, the control module first judges the difference between the total use time of the atomizer and the cumulative value of the use time of the atomizer before controlling the battery to supply power to the atomizer. difference and/or the difference between the total number of times of use of the atomizer and the cumulative value of the number of times of use of the atomizer, when the former is not greater than the first preset value and/or the latter is not greater than the second preset value, The control module controls the battery not to supply power to the atomizer, that is, does not start the atomizer anymore, and controls the battery 14 to stop supplying power to the atomizer 21 .

The second is that after the atomizer is started, the control module detects in real time whether the difference between the total use time of the atomizer and the cumulative value of the use time of the atomizer is not greater than the first preset value and/or the Whether the difference between the total number of times of use of the atomizer and the cumulative value of the number of times of use of the atomizer is not greater than the second preset value, if so, the control module controls the battery to stop supplying power to the atomizer, that is, to turn off the atomizer.

In this embodiment, since the atomization component carries the identification code, and when the battery component and the atomization component are electrically connected, the battery component can obtain the atomizer according to the identification code recognized by the identification code identification module in the battery component. The total length of use and/or the total number of times of use, and the use time and/or number of times of use of the atomizer after each startup is detected by the smoking detection module; in this way, the control module in the battery pack can detect the atomizer When the cumulative use time of the atomizer reaches the total use time of the atomizer and/or the cumulative number of use times of the atomizer reaches or approaches the total number of use times of the atomizer, the battery is controlled to stop being used for the atomizer The power supply of the atomizer avoids the situation that the e-liquid in the atomizer continues to work after use, and improves the user experience.

Preferably, in this embodiment, the method for preventing oil-free smoking further includes: when the battery assembly stops powering the atomizer, the battery pack assembly sends out a prompt signal. In this way, the user can be reminded that the e-liquid in the atomizer is exhausted, rather than that there is a problem with the battery component, so that the user can replace the atomizer and improve the user experience. There are several ways to signal an alert. Specifically, a light-emitting diode is arranged on the surface of the battery assembly, and the battery assembly sends out a prompt signal by lighting the light. Alternatively, the battery pack sends out a prompt signal by broadcasting a voice. Of course, the above is only an example and not a limitation.

Preferably, in this embodiment, the battery assembly also carries a battery identification code, which is used to uniquely identify the battery assembly. After the battery component identifies the identification code carried on the atomization component in the electronic cigarette, it further includes: the battery component detects whether there is a battery identification code in the atomization component; if not, the The battery assembly stores the battery identification code of the battery assembly in the atomization assembly. In this way, after the atomization component and the battery pack component form the electronic cigarette, when the battery component supplies power to the atomization component for the first time, the battery identification code of the battery pack component will be stored in the second memory in the atomization component.

If there is, the battery component detects whether the battery identification code in the atomization component is consistent with the battery identification code of the battery component, if they are consistent, control the battery to supply power to the atomizer, if not , the battery is controlled to stop supplying power to the atomizer. This way, different battery packs are prevented from powering the same atomizer pack. Since the use time and/or the cumulative value of the use times of the atomizer are stored in the battery component, avoiding different battery components to supply power to the atomization component can prevent the use time and/or the cumulative value of the use times of the atomizer from being different from the actual value.
