For those skilled in the art, the drawings of other embodiments can still be obtained according to the structures illustrated in the drawings without any creative effort.

The embodiments of the present application will be described in detail below. Throughout the specification, the same or similar components and components having the same or similar functions are denoted by similar reference numerals. The embodiments described herein with respect to the drawings are illustrative and graphical, and are used for providing a basic understanding of the present application. The embodiments of the present application should not be interpreted as limitations to the present application.

In some embodiments of the present application, an electronic vaporizer device is also referred to as an electronic cigarette, the electronic vaporizer device including an electronic vaporizer device body and an electronic vaporizer, the electronic vaporizer device body is also referred to as a cigarette rod, and the electronic vaporizer is also referred to as a cartridge. In some embodiments of the present application, the cartridge and the cigarette rod are separate structural components, and the cartridge is connected to the cigarette rod in a pluggable manner. The cartridge is engaged with the cigarette rod to form an electronic cigarette. In some embodiments of the present application, the cartridge and the cigarette rod are integrally formed structural components.

<FIG> is a schematic block diagram of an electronic cigarette according to some embodiments of the present application. The electronic cigarette <NUM> includes a cartridge <NUM> and a cigarette rod <NUM>. The cartridge <NUM> includes a heating circuit <NUM> for heating e-liquid or similar vaporizable substances stored in the cartridge <NUM> into a vaporization state, for the user to inhale or smoke. The cigarette rod <NUM> includes a main control circuit <NUM>, an indicator light <NUM>, and a battery <NUM>. The battery <NUM> serves as a power supply configured to supply power to the electronic cigarette <NUM> when the electronic cigarette <NUM> is in operation.

In some embodiments of the present application, the cigarette rod <NUM> further includes a charging circuit <NUM>. The charging circuit <NUM> is configured to connect to an external power supply to charge the battery <NUM>. The charging circuit <NUM> includes a USB type-C (a Universal Serial Bus Interface) interface that is connected to the external power supply via the USB type-C interface to charge the battery <NUM>. It should be noted that a specific form of the charging circuit <NUM> is not limited to the foregoing description.

<FIG> are schematic diagrams of a cartridge <NUM> and a cigarette rod <NUM> in an engaged state of an electronic cigarette <NUM> according to some embodiments of the present application. As shown in <FIG>, the cartridge <NUM> and the cigarette rod <NUM> are in a disengaged state. As shown in <FIG>, the cartridge <NUM> and the cigarette rod <NUM> are in an engaged state. The cartridge <NUM> is inserted into the cigarette rod <NUM> to form the engaged state in <FIG>. Because the cartridge <NUM> itself has resistance, when the cartridge <NUM> is inserted into the cigarette rod <NUM> and engaged with the cigarette rod <NUM>, the cartridge <NUM> divides a voltage. An output level of a circuit connected to the cartridge <NUM> is detected to determine whether the cartridge <NUM> is engaged with the cigarette rod <NUM>. Specifically, when a main control circuit <NUM> detects that the output level of the connection circuit is a high level, the cartridge <NUM> and the cigarette rod <NUM> are in a disengaged state. When the main control circuit <NUM> detects that the output level of the connection circuit is a low level, the cartridge <NUM> and the cigarette rod <NUM> are in an engaged state. The main control circuit <NUM> drives an indicator light <NUM> to operate in an alerting mode when the cartridge <NUM> and the cigarette rod <NUM> are detected to be in the engaged state. The alerting mode is: the indicator light <NUM> is bright and then gradually goes out, so that the user can be notified that the cartridge <NUM> and the cigarette rod <NUM> has been engaged and can be used normally. In some embodiments of the present application, the main control circuit <NUM> may also determine that the cartridge <NUM> and the cigarette rod <NUM> have not been engaged when the output level of the connection circuit is detected to be a low level, and determine that the cartridge <NUM> and the cigarette rod <NUM> have been engaged when the output level of the connection circuit is detected to be a high level.

It should be noted that, in the embodiment of the present application, the high level and the low level are different logic levels having relative voltage values. When the voltage is between V1 and V2, the level is high, and when the voltage is between V3 and V4, the level is low, where V1 is not less than V4. For example, <NUM>-<NUM> V may be predetermined as low level, and <NUM>-<NUM> V are predetermined as high level, but is not limited thereto and may be determined according to practical conditions.

In some embodiments of the present application, as shown in <FIG>, the cigarette rod <NUM> further includes a motor <NUM>. The main control circuit <NUM> controls, when the cartridge <NUM> and the cigarette rod <NUM> are detected to be in an engaged state, the motor <NUM> to operate in an alerting mode, that is, the motor <NUM> vibrates after a time T1. For example, the motor <NUM> may be controlled to vibrate once every <NUM> after the cartridge <NUM> and the cigarette rod <NUM> are in an engaged state, and the vibration time is <NUM>. The time and manner for vibration of the motor <NUM> are not limited to the foregoing description, and may be selected according to practical conditions. The motor <NUM> is vibrated to inform the user that the cartridge <NUM> and the cigarette rod <NUM> have been engaged and can be used normally. It should be noted that both the motor <NUM> and the indicator light <NUM> belong to the alerting device for alerting, in different modes, the user that the electronic cigarette is operating in different states. The alerting device may also include other alerting devices, for example, a display screen may be provided in the electronic cigarette <NUM> to alert the user by using an icon, a dynamic image, a text, or the like. In some embodiments of the present application, the alerting device further includes an acoustic generator and a vibrator.

In some embodiments of the present application, the cartridge <NUM> further includes an authentication circuit <NUM>. When the cartridge <NUM> and the cigarette rod <NUM> are in a disengaged state, the main control circuit <NUM> is non-electrically connected to the authentication circuit <NUM>. When the cartridge <NUM> and the cigarette rod <NUM> are in an engaged state, the main control circuit <NUM> is electrically connected to the authentication circuit <NUM>. The authentication circuit <NUM> includes a resistor that indicates flavor information of the cartridge <NUM>. When the cartridge <NUM> and the cigarette rod <NUM> are in an engaged state, the foregoing connection pin of the main control circuit <NUM> and the resistor form an electrical connection loop. Depending on different resistance values of the resistor in each cartridge <NUM>, the main control circuit <NUM> determines that a level of the connection pin corresponding to the resistor, and determines the cartridge <NUM> of different flavors according to different levels. For example, when the resistance is <NUM> ohms, it indicates that a grapefruit-flavor cartridge <NUM> is engaged with the cigarette rod <NUM>. When the resistance is <NUM> ohms, it indicates that a mint-flavor cartridge <NUM> is engaged with the cigarette rod <NUM>. It should be noted that a resistance value of a specific resistor and the flavor of the corresponding cartridge <NUM> are not limited thereto, which can be determined according to practical conditions.

In some embodiments of the present application, as shown in <FIG>, the cigarette rod <NUM> further includes an airflow sensor <NUM>. The airflow sensor <NUM> is electrically connected to the main control circuit <NUM>. In some embodiments of the present application, the main control circuit <NUM> enables the airflow sensor <NUM> when the output level of the connection circuit is detected to be a high level. In some embodiments of the present application, the main control circuit <NUM> enables the airflow sensor <NUM> when the output level of the connection circuit is detected to be a low level. Enabling the airflow sensor <NUM> may refer to supplying power to the airflow sensor <NUM>, or may refer to initializing the airflow sensor <NUM> to prepare the airflow sensor <NUM> for normal detection.

In some embodiments of the present application, when the cartridge <NUM> and the cigarette rod <NUM> are in an engaged state, the user can smoke or inhale normally. The airflow sensor <NUM> detects an airflow change when the user performs a vaping action. When the airflow sensor <NUM> detects the airflow, that is, when the air flows or changes, the airflow sensor <NUM> outputs a high level, that is, it indicates that the user is vaping. In this case, the main control circuit <NUM> controls a heating circuit <NUM> to perform heating to vaporize the e-liquid. When the airflow sensor <NUM> does not detect the airflow, that is, when no air flows or changes, the airflow sensor <NUM> outputs a low level, that is, it indicates that the user has stopped vaping. Then the main control circuit <NUM> controls a heating circuit <NUM> to stop heating. The main control circuit <NUM> records a start time t2 at which the high level is generated when the low level is detected to be converted into the high level, and records a start time t3 at which the low level is generated when the high level is detected to be converted into the low level next time. A time T2 = t3 - t2 for which the user takes one puff, where t3 is greater than t2. The main control circuit <NUM> performs counting and increases a count value C1 when T2 is greater than a preset threshold t4, for example, the count value may increase by <NUM>, t4 may be set to <NUM>, but is not limited thereto. When the count value C1 within a preset time T3 is greater than a preset threshold n, the main control circuit <NUM> drives the motor <NUM> and the indicator light to operate in the alerting mode. The alerting mode is: the motor <NUM> vibrates. For example, when the count value C1 is greater than <NUM> within <NUM> minutes of T3, the main control circuit <NUM> may drive the motor <NUM> to vibrate once for one second after the 15th puff with a vibration time of <NUM>, thereby effectively alerting the user to control the vaping amount and preventing excessive vaping.

In some embodiments of the present application, the airflow sensor <NUM> may also output a low level when the airflow is detected, and outputs a high level when no airflow is detected. The main control circuit <NUM> may determine whether the user is smoking according to level information that has different logic levels output by the airflow sensor <NUM>, and the specific determining manner is not limited to the foregoing.

In some embodiments of the present application, the main control circuit <NUM> disconnects the power supply from the battery <NUM> to the heating circuit <NUM> when T2 is greater than t5, so that the heating circuit <NUM> stops heating. For example, the control circuit <NUM> disconnects the power supply from the battery <NUM> from the heating circuit <NUM> when T2 is greater than <NUM>, so that the heating circuit <NUM> stops heating. In this way, the user can be prevented from smoking excessively.

In some embodiments of the present application, as shown in <FIG>, the cigarette rod <NUM> further includes a memory <NUM> and a wireless communication circuit <NUM>, both the memory <NUM> and the wireless communication circuit <NUM> being electrically connected to the main control circuit <NUM>. The memory <NUM> may be configured to store information and be read and written. The memory <NUM> stores smoking information, the smoking information including an ID of the cartridge <NUM>, the number of puffs, smoking time, and the like.

The wireless communication circuit <NUM> is used for performing wireless communication. The wireless communication may use one or more of the following modes: Bluetooth, Wi-Fi, the 3rd generation (<NUM>) mobile communication technology, the 4th generation (<NUM>) mobile communication technology, the 5th generation (<NUM>) mobile communication technology, near field communication, ultrasonic communication, ZigBee (ZigBee protocol), radio frequency identification (RFID), and the like. The main control circuit <NUM> interacts with an intelligent terminal through the wireless communication circuit <NUM>. The intelligent terminal includes a mobile phone, a computer, an intelligent wearable apparatus (for example, an intelligent watch), a tablet, and the like.

In some embodiments of the present application, as shown in <FIG>, the cigarette rod <NUM> further includes an acceleration sensor <NUM>, the acceleration sensor <NUM> being electrically connected to the main control circuit <NUM>. In some embodiments of the present application, the main control circuit <NUM> enables the acceleration sensor <NUM> when the output level of the connection circuit is detected to be a high level. In some embodiments of the present application, the main control circuit <NUM> enables the airflow sensor <NUM> when the output level of the connection circuit is detected to be a low level. Enabling the acceleration sensor <NUM> may refer to supplying power to the airflow sensor <NUM>, or may refer to initializing the acceleration sensor <NUM> to prepare the acceleration sensor <NUM> for normal detection.

In some embodiments of the present application, the main control circuit <NUM> obtains acceleration information of the acceleration sensor <NUM>, and enables the wireless communication circuit <NUM> when an acceleration value included in the acceleration information is greater than a preset threshold a1. The acceleration value includes at least one of an acceleration value in an X-axis direction, an acceleration value in a Y-axis direction, or an acceleration value in a Z-axis direction in a coordinate system. The acceleration sensor <NUM> is a G-sensor (a gravity sensor), but is not limited thereto. A case that the acceleration value is greater than the preset threshold a1 may indicate that the user is shaking the electronic cigarette <NUM>. For example, when the wireless communication circuit <NUM> includes a Bluetooth module and performs wireless communication using the Bluetooth module, the main control circuit <NUM> enables the Bluetooth module when the obtained acceleration value is greater than the preset threshold a1, and sends a broadcast signal through the Bluetooth module. In addition, the main control circuit <NUM> is further configured to operate in a fourth driving mode when the obtained acceleration value is greater than the preset threshold a1 and the count value C1 is increased, and the fourth driving mode is: controlling the indicator light <NUM> to flash <NUM> times, to remind the user that the Bluetooth mode of the electronic cigarette <NUM> is enabled. In addition, if the user performs the shaking action again, the indicator light <NUM> will flash again <NUM> times. In this case, the user may perform Bluetooth matching with the electronic cigarette <NUM> through the intelligent terminal, and perform Bluetooth communication after the matching is performed successfully. The main control circuit <NUM> may send or transmit the smoking information stored in the memory <NUM> to the intelligent terminal through Bluetooth communication. A dedicated application (APP) of the intelligent terminal performs data analysis according to the received smoking information to better guide the user to control smoking, reduce or quit smoking.

In some embodiments of the present application, the authentication circuit <NUM> includes an encryption chip (not shown in the figure). The encryption chip stores encrypted data information of the cartridge <NUM>, the data information including a unique ID number, a flavor of the cartridge, an amount of tar of the cartridge, and the like. The main control circuit <NUM> includes a decryption module corresponding to the encryption chip, and the decryption module includes a decryption chip. The decryption module is configured to decrypt the encrypted information when the cartridge <NUM> and the cigarette rod <NUM> are in an engaged state, send or transmit decryption success information when the decryption is successful, and send or transmit decryption failure information when the decryption fails. Upon receiving the decryption failure information, the main control circuit <NUM> disconnects the battery <NUM> from the heating circuit <NUM>. If the decryption success message is received, the main control circuit <NUM> drives the indicator light <NUM> to flash three times and drives the motor <NUM> to vibrate for a short time three times. The main control circuit <NUM> enables the Bluetooth module to transmit the broadcast signal after successfully decrypting the encrypted data information obtained from the encryption chip.

<FIG> is a schematic diagram of interaction between an electronic cigarette <NUM> and an intelligent terminal according to some embodiments of the present application. An intelligent terminal <NUM> turns on the Bluetooth and matches the electronic cigarette <NUM>, and receives the data information sent or transmitted by the electronic cigarette <NUM> after the matching is successful. The intelligent terminal <NUM> sends or transmits the foregoing data information to a server <NUM>, and the server <NUM> is configured to send analyzed and processed information about the electronic cigarette <NUM> to the intelligent terminal <NUM>. The intelligent terminal <NUM> displays the data information of the cartridge <NUM> by the dedicated APP, including information such as the flavor of the cartridge, the number of puffs per day, the number of puffs per week, the number of puffs per month, the number of accumulated puffs, and an amount of remaining e-liquid, which are displayed as a graph. The amount of remaining e-liquid may be obtained according to the number of accumulated puffs for the cartridge <NUM>.

In some embodiments of the present application, when the electronic cigarette <NUM> and the intelligent terminal <NUM> are in a Bluetooth connection state, the "stop heating" touch control widget on the dedicated APP is activated by the user, and the intelligent terminal <NUM> obtains the "stop heating" instruction, and transmits the "stop heating" instruction to the main control circuit <NUM> via a Bluetooth communication link. Upon receiving the "stop heating" instruction, the main control circuit <NUM> disconnects the power supply from the battery <NUM> to the heating circuit <NUM>, and the heating circuit <NUM> stops heating. Even if the airflow sensor <NUM> detects the airflow and outputs a high level, that is, the user is vaping, the heating circuit <NUM> is not powered either; that is, the heating circuit <NUM> cannot heat the e-liquid.

In some embodiments of the present application, the electronic cigarette <NUM> is also prohibited or forbidden from being used in a non-smoking area. The intelligent terminal <NUM> has a locating or positioning function. When the user carries the intelligent terminal <NUM> and the electronic cigarette <NUM> into a virtual geofence <NUM>, as shown in <FIG>, the intelligent terminal <NUM> and the electronic cigarette <NUM> are in a Bluetooth connection state. The intelligent terminal <NUM> automatically receives a notification of "entering the fence". The intelligent terminal <NUM> sends a "no smoking" instruction to the electronic cigarette <NUM> when determining that a current location is within the geofence <NUM>, that is, belongs to the non-smoking area. The main control circuit <NUM> of the electronic cigarette <NUM> is switched to the "no smoking" mode upon receiving the "no smoking" instruction, that is, disconnects the electrical connection between the battery <NUM> and the heating circuit <NUM>, and the heating circuit <NUM> is prohibited or forbidden from enabling the heating function, and does not respond to level information output by the airflow sensor <NUM>. In other words, even if the airflow sensor <NUM> detects the airflow and outputs a high level, that is, the user is vaping, the heating circuit <NUM> is not powered either, that is, the heating circuit <NUM> cannot heat the e-liquid. Therefore, even if the user performs the vaping action on the electronic cigarette <NUM> after entering the non-smoking area, the electronic cigarette <NUM> would not heat the e-liquid to form an atomized state, so that the user can be effectively prevented from illegally smoking.

The geofence <NUM> may be a virtual geographic boundary defined using any geofence technology, for example, an airport, a gas station, a mall, and the like. In addition, if the intelligent terminal <NUM> enters the geofence <NUM> and the intelligent terminal <NUM> determines that the geofence <NUM> does not belong to the non-smoking area, the "no smoking" instruction would not be sent to the electronic cigarette <NUM>.

Specifically, as shown in <FIG>, the main control circuit <NUM> includes a switch <NUM> and a switch <NUM>. The switch <NUM> and the switch <NUM> are connected in series and are disposed in a circuit between the battery <NUM> and the heating circuit <NUM>. When both the switch <NUM> and the switch <NUM> are switched or turned on, the battery <NUM> supplies power to the heating circuit <NUM> normally, causing the heating circuit <NUM> to heat the e-liquid. When at least one of the switch <NUM> and the switch <NUM> is switched or turned off, the battery <NUM> and the heating circuit <NUM> are in an open circuit state, and the heating circuit <NUM> would not perform heating. In some embodiments of the present application, the main control circuit <NUM> controls switching or turning the switch <NUM> on when the no-smoking instruction is not received and the current location is detected to not belong to first location information, and controls switching or turning the switch <NUM> on when determining that the received output level of the connection circuit is a high level, and the battery <NUM> supplies power to the cartridge <NUM> when both the switch <NUM> and the switch <NUM> are switched or turned on. In some embodiments of the present application, the main control circuit <NUM> controls switching or turning the switch <NUM> on when the no-smoking instruction is not received and the current location is detected to not belong to first location information, and controls switching or turning the switch <NUM> on when determining that the received output level of the connection circuit is a low level, and the battery <NUM> supplies power to the cartridge <NUM> when both the switch <NUM> and the switch <NUM> are switched or turned on.

The main control circuit <NUM> controls, using control pins of the switch <NUM> and the switch <NUM>, the switch <NUM> and the switch <NUM> to be switched on or off. The switch <NUM> remains switch-on by default. When receiving the "no smoking" instruction, the main control circuit <NUM> controls the switch <NUM> to be switched from the switch-on state to the switch-off state, that is, the electronic cigarette <NUM> is switched to the "no smoking" mode. Even if the airflow sensor <NUM> detects the airflow and outputs a high level, that is, the user is vaping, the main control circuit <NUM> switches the switch <NUM> off according to a high level signal, and the battery <NUM> and the heating circuit <NUM> are still in a switch-off state. In this case, the heating circuit <NUM> does not perform heating.

When the main control circuit <NUM> does not receive the "no smoking" instruction, the switch <NUM> is in a switch-on state. When the airflow sensor <NUM> detects the airflow and outputs a high level, that is, when the user is vaping, the main control circuit <NUM> switches the switch <NUM> on according to the high level signal. In this case, because both the switch <NUM> and the switch <NUM> are switched on, the battery <NUM> normally supplies power to the heating circuit <NUM>, so that the heating circuit <NUM> heats the e-liquid, and the user can normally vape via the electronic cigarette <NUM>.

As shown in <FIG>, when the intelligent terminal <NUM> and the electronic cigarette <NUM> leave the geofence <NUM> belonging to the non-smoking area, the intelligent terminal <NUM> automatically receives the notification of "leaving the fence" and sends an "allow smoking" instruction to the electronic cigarette <NUM>. The main control circuit <NUM> of the electronic cigarette <NUM> is switched to an "allow smoking" mode upon receiving the "allow smoking" instruction. That is, when the main control circuit <NUM> is switched to the "allow smoking" mode, the airflow sensor <NUM> detects the airflow and outputs a high level, that is, it indicates that the user is vaping, and the main control circuit <NUM> controls the heating circuit <NUM> to heat the e-liquid to vaporize the e-liquid.

Specifically, as shown in <FIG>, the main control circuit <NUM> switches the switch <NUM> from the switch-off state to the switch-on state upon receiving the "allow smoking" instruction, that is, the electronic cigarette <NUM> is switched to the "allow smoking" mode. In this case, when the airflow sensor <NUM> detects the airflow and outputs a high level, that is, it indicates that the user is vaping normally, and the main control circuit <NUM> switches the switch <NUM> to the switch-on state according to the high level signal. Because both the switch <NUM> and the switch <NUM> are in the switch-on state, the battery <NUM> normally supplies power to the heating circuit, so that the heating circuit <NUM> heats the e-liquid to form a vaporized state, and the user can normally vape via the electronic cigarette <NUM>.

<FIG> is a schematic block diagram of an electronic cigarette <NUM> according to some embodiments of the present application. A cigarette rod <NUM> further includes a positioning module <NUM>. The positioning module <NUM> is electrically connected to a main control circuit <NUM>. The positioning module <NUM> has a locating or positioning function and is configured to obtain location or position information. The positioning module <NUM> includes a Global Positioning System (GPS) positioning module, a BeiDou positioning module, a Global Navigation Satellite System (GLONASS) positioning module, or the like.

In some embodiments of the present application, when a user carries the electronic cigarette <NUM> as shown in <FIG> into a geofence <NUM>, as shown in <FIG>, after the electronic cigarette <NUM> automatically receives, through the wireless communication circuit <NUM>, a notification of "entering the fence" sent by the geofence <NUM>, the main control circuit <NUM> determines that a current location is within the geofence <NUM>, that is, after the current location belongs to non-smoking area information, a heating circuit <NUM> is prohibited from heating. Even if an airflow sensor <NUM> detects the airflow and outputs a high level, that is, when the user is vaping, the heating circuit <NUM> is not powered either, that is, the heating circuit <NUM> cannot heat the e-liquid.

Referring back to <FIG>, the switch <NUM> remains in the switch-on state by default. When determining that the current location is within the geofence <NUM>, that is, after the current location belongs to the non-smoking area, the main control circuit <NUM> controls the switch <NUM> to be switched from the switch-on state to the switch-off state, that is, the electronic cigarette <NUM> is switched to the "no smoking" mode. Even if the airflow sensor <NUM> detects the airflow and outputs a high level, that is, the user is vaping, the main control circuit <NUM> switch off the switch <NUM> according to a high level signal, and the battery <NUM> and the heating circuit <NUM> are still in an open circuit state. In this case, the heating circuit <NUM> would not perform heating.

When determining that the current location is outside the geofence <NUM>, that is, the current location does not belong to the non-smoking area, the main control circuit <NUM> maintains the switch <NUM> in the switch-on state. When the airflow sensor <NUM> detects the airflow and outputs a high level, that is, when the user is vaping, the main control circuit <NUM> closes the switch <NUM> according to the high level signal. In this case, because both the switch <NUM> and the switch <NUM> are switched on, the battery <NUM> normally supplies power to the heating circuit <NUM>, so that the heating circuit <NUM> heats the e-liquid, and the user can normally vape via the electronic cigarette <NUM>.

When the user carries the electronic cigarette <NUM> as shown in <FIG> away from the geofence <NUM> belonging to the non-smoking area, as shown in <FIG>, after the electronic cigarette <NUM> automatically receives, through a wireless communication circuit <NUM>, a notification of "leaving the fence" sent by the geofence <NUM>, the main control circuit <NUM> is switched to an "allow smoking" mode. That is, when the main control circuit <NUM> is switched to the "allow smoking" mode, the airflow sensor <NUM> detects the airflow and outputs a high level, that is, it indicates that the user can vape, and the main control circuit <NUM> controls the heating circuit <NUM> to heat the e-liquid to vaporize the e-liquid.

Referring back to <FIG>, the main control circuit <NUM> switches the switch <NUM> from the switch-off state to the switch-on state upon receiving the notification of "leaving the fence", that is, the electronic cigarette <NUM> is switched to the "allow smoking" mode. In this case, when the airflow sensor <NUM> detects the airflow and outputs a high level, that is, it indicates that the user can vape normally, the main control circuit <NUM> switches the switch <NUM> to the switch-on state according to the high level signal. Because both the switch <NUM> and the switch <NUM> are in the switch-on state, the battery <NUM> normally supplies power to the heating circuit, so that the heating circuit <NUM> heats the e-liquid to form the vaporization state, and the user can normally vape via the electronic cigarette <NUM>.

<FIG> is a flowchart of an operation method according to some embodiments of the present application. The operation method in <FIG> is used for the electronic cigarette <NUM> in one or more of the foregoing embodiments.

In step <NUM>, the main control circuit <NUM> detects an output level of a connection circuit. The connection circuit is a circuit for being connected to a cartridge <NUM>. Because the cartridge <NUM> itself is provided with resistance, when the cartridge <NUM> is inserted into the cigarette rod <NUM> and engaged with the cigarette rod <NUM>, the cartridge <NUM> generates a divided voltage in the connection circuit. It may be determined, according to the output level of the connection circuit, whether the cartridge <NUM> is engaged with the cigarette rod <NUM>.

In step <NUM>, it is determined whether the output level is a low level. If yes, go to step <NUM>; if no, indicating that the cartridge <NUM> is not engaged with the cigarette rod <NUM> and going back to step <NUM>, the main control circuit <NUM> continuously detects the output level of the connection circuit.

In step <NUM>, the main control circuit <NUM> drives an indicator light <NUM> and a motor <NUM> to operate in an alerting mode. The alerting mode is that: the indicator light <NUM> is turned on after the cartridge <NUM> is engaged with the cigarette rod <NUM>, and gradually goes out; and the motor <NUM> vibrates once after the cartridge <NUM> is engaged with the cigarette rod <NUM> for <NUM>, with a vibration time of <NUM>. The alerting mode is not limited thereto, which can be set according to practical conditions. In this way, the user can be reminded or informed that the cartridge <NUM> has been engaged with the cigarette rod <NUM> to be used normally.

<FIG> is a flowchart of an operation method according to some embodiments of the present application. The operation method in <FIG> may be used for the electronic cigarette <NUM> in one or more of the foregoing embodiments.

In step <NUM>, the main control circuit <NUM> detects whether the cartridge <NUM> is engaged with the cigarette rod <NUM>. If yes, go to step <NUM>; or if no, continue performing the detection.

In step <NUM>, the main control circuit <NUM> obtains a vaping time T2 from when the user takes a puff. Specifically, when the airflow sensor <NUM> detects an airflow, the airflow sensor <NUM> outputs a high level, that is, it indicates that the user is vaping, and in this case, the main control circuit <NUM> controls a heating circuit <NUM> to perform heating to vaporize the e-liquid. When the airflow sensor <NUM> does not detect an airflow, the airflow sensor <NUM> outputs a low level, that is, it indicates that the user has stopped vaping, and the main control circuit <NUM> controls the heating circuit <NUM> to stop heating. The main control circuit <NUM> records a start time t2 at which the high level is generated when the low level is detected and changed to the high level, and records a start time t3 at which the low level is generated when the high level is detected and changed to the low level. The vaping time T2 = t3 - t2 for which the user takes each puff, where t3 is greater than t2.

In step <NUM>, the main control circuit <NUM> detects whether the vaping time T2 for which the user takes each puff is greater than a preset threshold t4. If yes, go to step <NUM>. If no, go to step <NUM> to keep the number C1 of vaping puffs unchanged.

In step <NUM>, add <NUM> to the number C1 of vaping puffs. In step <NUM>, keep the number C1 of vaping puffs unchanged.

In step <NUM>, the main control circuit <NUM> determines whether the number C1 of vaping puffs within a vaping time T3 is greater than a preset threshold n. If C1 is greater than n, go to step <NUM>; or if C1 is less than n, go back to step <NUM>.

In step <NUM>, the main control circuit <NUM> drives a motor <NUM> to operate in an alerting mode. The alerting mode is: the motor <NUM> vibrates once, and a vibration time is <NUM>. The alerting mode is not limited thereto. In this way, the alerting mode may be configured to remind or inform a user to control the vaping amount to prevent excessive smoking.

In step <NUM>, the main control circuit <NUM> obtains an acceleration value of the acceleration sensor <NUM>. The acceleration value may include at least one of an acceleration value in an X-axis direction, an acceleration value in a Y-axis direction, or an acceleration value in a Z-axis direction in a coordinate system. The acceleration sensor <NUM> is a G-sensor (a gravity sensor), but is not limited thereto.

In step <NUM>, the main control circuit <NUM> determines whether the obtained acceleration value is greater than a preset threshold. If yes, it indicates that the user is shaking the cigarette rod <NUM>, and proceeds to step <NUM>; or if no, goes back to step <NUM>.

In step <NUM>, the main control circuit <NUM> enables the wireless communication circuit <NUM> to transmit a wireless signal, and drives the indicator light <NUM> to operate in the alerting mode.

Specifically, the wireless communication circuit <NUM> may include the Bluetooth module, and the main control circuit <NUM> enables the Bluetooth module when performing wireless communication by using the Bluetooth module and when the obtained acceleration value is greater than the preset threshold, and sends or transmits the broadcast signal through the Bluetooth module. In addition, a third alerting mode is when the indicator light <NUM> flashes for <NUM> times, to remind the user that a Bluetooth mode of an electronic cigarette <NUM> is enabled. In addition, if the user performs the shaking action again, the indicator light <NUM> will flash again for <NUM> times.

In some embodiments of the present application, when the cartridge <NUM> is not engaged with the cigarette rod <NUM>, the through hole <NUM> for ventilation of the battery holder cap <NUM> in the cigarette rod <NUM> may enable outside air to be in communication with the airflow detection through hole of the airflow sensor <NUM>.

<FIG> is a schematic structural diagram of an airflow channel of the electronic cigarette <NUM> according to some embodiments of the present application. As shown in <FIG>, when the cartridge <NUM> is engaged with the cigarette rod <NUM>, there is a gap between an outer side wall of a lower tube body <NUM> of the cartridge <NUM> and an inner side wall of a housing <NUM> of the cigarette rod <NUM>, and there is also a gap for ventilation between a bottom cap <NUM> of the cartridge <NUM> and a battery holder cap <NUM> of the cigarette rod <NUM>. The airflow enters an airflow detection through hole of an airflow sensor <NUM> through the through hole <NUM> for air circulation of the battery holder cap <NUM>, to form an airflow channel f1 for communicating outside air of the electronic cigarette <NUM> with the airflow sensor <NUM> of the electronic cigarette. In this way, the outside air of the electronic cigarette <NUM> can effectively enter.

When the cartridge <NUM> of the electronic cigarette <NUM> is engaged with the cigarette rod <NUM>, when the user performs a vaping action, the airflow at the airflow detection through hole of the airflow sensor <NUM> passes through the through hole <NUM> at the battery holder cap <NUM> to enter the gap between the bottom cap <NUM> and the battery holder cap <NUM>, that is, the air flow is detected, the air flow changes, and a high level is output. A main control module <NUM> enables the battery <NUM> to supply power to the heating component <NUM>, and the heating component <NUM> heats the e-liquid. Then, air enters the space between the heating component <NUM> and the tar absorbing pad <NUM> through the air tube <NUM> and the through hole <NUM>. At this time, some e-liquid is vaporized by heating, and the airflow brings smoke formed by vaporizing the e-liquid into the airflow channel <NUM> through the side end opening <NUM>, and the smoke enters the user's mouth through corresponding through holes on the upper tube <NUM> and a vaping cap <NUM>, thereby forming the airflow channel f2 to achieve a smoking action. It should be noted that during a vaping process, the air also enters the air tube <NUM> through the airflow channel f1.

In some embodiments of the present application, referring back to <FIG>, when the cartridge <NUM> is not inserted into the cigarette rod <NUM>, there is no load between the pogo pin <NUM> and the pogo pin <NUM>, and the main control module <NUM> detects that a high level exists between the pogo pin <NUM> and the pogo pin <NUM>. As shown in <FIG>, when the cartridge <NUM> is inserted into the cigarette rod <NUM>, the pogo pin <NUM> and the pogo pin <NUM> are electrically connected to the contact pad of the PCB module <NUM>, that is, a current loop is formed between the PCB module <NUM> as a load and the pogo pin <NUM> and the pogo pin <NUM>. In this case, because the PCB module <NUM> as a load may divide a voltage, the main control module <NUM> detects that a low level exists between the pogo pin <NUM> and the pogo pin <NUM>, and the main control module <NUM> drives the indicator light <NUM> and the motor <NUM> to operate in the alerting mode. The alerting mode is: the indicator light <NUM> is turned on after the cartridge <NUM> and the cigarette rod <NUM> are engaged, and gradually goes out; and after the cartridge <NUM> and the cigarette rod <NUM> vibrates once after being engaged for <NUM>, with a vibration time of <NUM>. The alerting mode is not limited thereto, which can be set according to practical conditions. In this way, the user can be reminded and informed that the cartridge <NUM> and the cigarette rod <NUM> have been engaged and can be used normally. In some embodiments of the present application, the main control module <NUM> may also determine that the cartridge <NUM> and the cigarette rod <NUM> have not been engaged when an output level of the connection circuit formed by the pogo pin <NUM> and the pogo pin <NUM> of the cigarette rod <NUM> is detected to be a low level, and determine that the cartridge <NUM> and the cigarette rod <NUM> have been engaged when the output level of the connection circuit is detected to be a high level.

When the user determines, according to the indicator light <NUM> and the motor <NUM>, that the electronic cigarette <NUM> has been engaged, the user may start a normal vaping action.

When the user does not perform an inhalation or vaping action, the airflow sensor <NUM> does not detect the airflow change, and the airflow sensor <NUM> outputs a low level. When the user performs the inhalation or vaping action, the airflow sensor <NUM> detects the airflow, and the output level of the airflow sensor <NUM> changes from a low level to a high level. The main control module <NUM> outputs a voltage through the pogo pin <NUM> and the pogo pin <NUM> when receiving a signal indicating that the output level of the airflow sensor <NUM> changes from a low level to a high level, and provides the output voltage to the heating component <NUM> via the contact pad of the PCB module <NUM>, the elastic piece <NUM>, the elastic piece <NUM>, the pin <NUM>, and the pin <NUM>, so that the heating component <NUM> performs heating, and the e-liquid in contact with the heating component <NUM> is vaporized. In addition, when the user vapes, air enters the cartridge <NUM> through the air tube <NUM>, and the smoke in the vaporized state is fed to the user's mouth through the airflow channel, thereby completing an action of smoking once. When the smoking action is stopped, the airflow change in the electronic cigarette <NUM> stops, the airflow sensor <NUM> does not detect an airflow change, and the output level of the airflow sensor <NUM> changes from a high level to a low level. In this case, the main control module <NUM> controls disconnecting the output voltage between the pogo pin <NUM> and the pogo pin <NUM> after obtaining the signal indicating that the output level changes from the high level to the low level, that is, the heating component <NUM> stops heating. The main control module <NUM> records a start time t2 at which the high level is generated when the output level of the airflow sensor <NUM> is detected to change from the low level to the high level, and records a start time t3 at which the low level is generated when the output level of the airflow sensor <NUM> is detected to change from the high level to the low level next time. A time T2 = t3 - t2 for which the user takes one puff, where t3 is greater than t2. The main control module <NUM> performs counting and increases a count value C1 when T2 is greater than a preset threshold t4, for example, may increase the count value by <NUM>. t4 may be set to <NUM>, but is not limited thereto. If the user keeps performing the vaping action, when the count value C1 within time T3 is greater than a preset threshold n, the main control module <NUM> drives the motor <NUM> to operate in the alerting mode. The alerting mode is: the motor <NUM> vibrates. For example, when the count value C1 is greater than <NUM> within <NUM> minutes of T3, the main control module <NUM> may drive the motor <NUM> to vibrate once for a short time for one second after the 15th puff with a vibration time of <NUM>, thereby effectively alerting the user to control the vaping amount and prevent excessive vaping.

In some embodiments of the present application, the airflow sensor <NUM> may also output a low level when the airflow is detected, and outputs a high level when no airflow is detected. The main control module <NUM> may determine whether the user is smoking according to the level information that has different logic levels and output by the airflow sensor <NUM>, and a specific determining manner is not limited to the foregoing.

In some embodiments of the present application, the main control module <NUM> stops the power supply of the battery <NUM> to the heating component <NUM> when T2 is greater than t5, so that the heating component <NUM> stops being heated. For example, the main control module <NUM> stops the power supply of the battery <NUM> to the heating component <NUM> when T2 is greater than <NUM>, so that the heating component <NUM> stops being heated. In this way, the user can be prevented from smoking excessively.

In some embodiments of the present application, after the cartridge <NUM> and the cigarette rod <NUM> are engaged, the main control module <NUM> detects data information of the authentication circuit <NUM> electrically connected to the pogo pin <NUM> in the PCB module <NUM>. In some embodiments, the authentication circuit <NUM> includes a resistor that indicates flavor information of the cartridge <NUM>, that is, different resistance values correspond to different flavors of the cartridge. For example, when the resistance is <NUM> ohms, it indicates that the cartridge <NUM> with a grapefruit-flavor is engaged with the cigarette rod <NUM>. When the resistance is <NUM> ohms, it indicates that the cartridge <NUM> with a mint-flavor is engaged with the cigarette rod <NUM>. It should be noted that a resistance value of a specific resistor and the flavor of the corresponding cartridge <NUM> are not limited thereto, which can be determined according to practical conditions. When the main control module <NUM> detects that the resistance of the resistor connected to the pogo pin <NUM> is <NUM> ohms, it indicates that the cartridge <NUM> is the cartridge with a grapefruit-flavor.

In some embodiments of the present application, the authentication circuit <NUM> includes an encryption chip (not shown in the figure). The encryption chip stores encrypted data information of the cartridge <NUM>, the data information including a unique ID number, a flavor of the cartridge, an amount of tar of the cartridge, and the like. The main control module <NUM> includes a decryption module corresponding to the encryption chip, and the decryption module includes a decryption chip. The decryption module is configured to decrypt the encrypted information when the cartridge <NUM> and the cigarette rod <NUM> are in the engaged state, send or transmitting decryption success information when the decryption is successful, and transmit decryption failure information when the decryption fails. After the decryption success information is received, the main control module <NUM> supplies power to the main control module <NUM> between the battery <NUM> and the heating circuit <NUM> to drive the indicator light <NUM> to flash three times and drive the motor <NUM> to vibrate for a short time three times. The main control module <NUM> enables a Bluetooth mode and transmits a broadcast signal by the antenna <NUM> after successfully decrypting the encrypted data information obtained from the encryption chip.

In some embodiments of the present application, the main control module <NUM> does not respond to changes in voltage or current between the pogo pin <NUM> and the pogo pin <NUM> upon receiving the decryption failure information. In some embodiments of the present application, the main control module <NUM> responds to changes in voltage or current between the pogo pin <NUM> and the pogo pin <NUM> upon receiving the decryption success information. In some embodiments of the present application, the main control module <NUM> does not respond to level information output by the airflow sensor <NUM> upon receiving the decryption failure information. In some embodiments of the present application, the main control module <NUM> responds to level information output by the airflow sensor <NUM> upon receiving the decryption success information.

In some embodiments of the present application, the main control module <NUM> obtains an acceleration value of an acceleration sensor <NUM>, and determines a downtilt angle of the cartridge <NUM> according to the obtained acceleration value. As shown in <FIG>, when the electronic cigarette <NUM> is placed horizontally, that is, the electronic cigarette <NUM> as shown in the state A. A downtilt angle determined by the main control module <NUM> is <NUM>°, and in this case, the main control module <NUM> does not output any action instruction. When the electronic cigarette <NUM> is placed obliquely and a mouthpiece <NUM> is inclined downward, the main control module <NUM> determines that the downtilt angle is not less than a preset threshold α. α may be set to <NUM>° and is saved or stored in a memory <NUM>, but is not limited thereto. For the electronic cigarette <NUM> in the state B in <FIG>, when the user vapes via the electronic cigarette <NUM> and tilts the mouthpiece <NUM> downward, it may be determined that the user is vaping via the electronic cigarette <NUM> in an inversed manner. However, because the mouthpiece <NUM> of the electronic cigarette <NUM> being inclined downward causes the e-liquid in the storage compartment <NUM> not to penetrate into the heating component <NUM> through the heat-conducting top cap <NUM> and the heat-conducting silica gel <NUM> as a result of gravity influence. Therefore, when the user vapes the electronic cigarette in an inversed manner for too long, the e-liquid in the heating component <NUM> is dried out, causing the dry burning of the heating component <NUM> with a burnt flavor.

Therefore, when the electronic cigarette <NUM> is placed obliquely and the mouthpiece <NUM> is tilted downward, the main control module <NUM> determines that the downtilt angle is not less than a preset threshold α, and also detects that the output level of the airflow sensor <NUM> is a high level. In addition, when a vaping time T2 is greater than the preset threshold t4, the main control module <NUM> drives the motor <NUM> to vibrate in a fourth driving mode. The fourth driving mode is: driving the motor <NUM> to vibrate three times, a vibration time being <NUM> each time. Therefore, the user is alerted or informed to avoid the burnt flavor generated by the dry burning of the heating component <NUM> caused by excessively long vaping time inversely, thereby improving user experience. In some embodiments of the present application, the tilt angle determined by the main control module <NUM> may be a positive value or a negative value, the positive value and the negative value being used to indicate different downtilt directions. The positive value indicates that the mouthpiece <NUM> is tilted down, which is an inverse vaping state; and the negative value indicates that the mouthpiece <NUM> is tilted up, which is a normal use state.

In some embodiments of the present application, the main control module <NUM> enables the wireless communication function when the acceleration value of the acceleration sensor <NUM> is detected to be greater than the preset threshold a1, that is, transmits the broadcast signal by the antenna <NUM>. The wireless communication function may be a Bluetooth function, and the antenna <NUM> may be a Bluetooth antenna, but is not limited thereto, as described above, which may be selected according to a specific situation. In addition, the main control module <NUM> drives the indicator light <NUM> in a third driving mode, the third driving mode being that the indicator light <NUM> flashes <NUM> times, to remind the user that the Bluetooth mode of the electronic cigarette <NUM> has been enabled. In addition, if the acceleration value is detected to be greater than the preset threshold value again within the preset time, that is, the user performs the shaking action again, the main control module <NUM> continues to drive the indicator light in the third driving mode. After the user learns that the Bluetooth mode of the electronic cigarette <NUM> is enabled, the user may perform Bluetooth matching with the electronic cigarette via a mobile phone to obtain the user smoking information and related data information of the cartridge <NUM> of the electronic cigarette <NUM>.
