[0053] Embodiments of the present application will be described in detail hereinafter. Throughout the specification of the present application, components that are the same or similar and components having the same or similar functions are denoted by like reference numerals. The embodiments of the related drawings described herein are illustrative, diagrammatic, and are used to provide a basic understanding of the present application. The embodiments of the present application should not be construed as a limitation of the present application.

[0054] In some embodiments of the present application, the electronic atomizer device is also referred to as an electronic cigarette. The electronic atomizer device includes an electronic atomizer device body and an electronic atomizer. The electronic atomizer device body is also referred to as a cigarette rod, and the electronic atomizer is also referred to as a cartridge. In some embodiments of the present application, the cartridge and the cigarette rod are separate individual structural members, and the cartridge is detachably connected to the cigarette rod. After the cartridge and the cigarette rod are combined, an electronic cigarette is formed. In some embodiments of the present application, the cartridge and the cigarette rod are integrally formed structural members.

[0055] Figure 1 Principle block diagram of the electronic cigarette for some embodiments of the present application. The electronic cigarette 10 includes a cartridge 11 and a cigarette rod 12. The cartridge 11 includes a heating circuit 111, and the heating circuit 111 is used to heat the e-liquid or similar atomizable substance stored in the cartridge 11 to form an atomized state, so that it can be sucked by the user. The cigarette rod 12 includes an active control circuit 123, an indicator light 126, and a battery 127. Among them, the battery 127 serves as a power source to supply power to the electronic cigarette 10 when the cartridge 11 is working.

[0056] In some embodiments of the present application, the cigarette rod 12 further includes a charging circuit 128. The charging circuit 128 is used to connect to an external power source to charge the battery 127. The charging circuit 128 includes a USB-Type C (a universal serial bus interface specification) interface, and the external power source is connected through the USB-Type C interface to charge the battery 127. It should be noted that the specific form of the charging circuit 128 is not limited to the above description.

[0057] Figures 2A - 2B Schematic diagram of the combined state of the cartridge 11 and the cigarette rod 12 of the electronic cigarette 10 for some embodiments of the present application. As Figure 2AAs shown, the cartridge 11 and the rod 12 are in an uncoupled state. As Figure 2B shown, the cartridge 11 and the rod 12 are in a coupled state. Among them, the cartridge 11 forms a Figure 2B coupled state in the rod 12 by being inserted into it. Since the cartridge 11 itself has a resistance, when the cartridge 11 is inserted into the rod 12 and coupled with the rod 12, the cartridge 11 will share the voltage. By detecting the output level of the circuit connected to the cartridge 11, it is determined whether the cartridge 11 and the rod 12 are coupled. Specifically, when the main control circuit 123 detects that the output level of the connection circuit is high, the cartridge 11 and the rod 12 are in an uncoupled state. When the main control circuit 123 detects that the output level of the connection circuit is low, the cartridge 11 and the rod 12 are in a coupled state. When the main control circuit 123 detects that the cartridge 11 and the rod 12 are in a coupled state, it drives the indicator light 126 to work in a reminder mode, and the reminder mode is: the indicator light 126 lights up and then gradually goes out, so as to inform the user that the cartridge 11 and the rod 12 are coupled and can be used normally. In some embodiments of the present application, the main control circuit 123 can also detect that the output of the connection circuit is low, confirm that the cartridge 11 and the rod 12 are uncoupled, and confirm that the cartridge 11 and the rod 12 are coupled when detecting that the output of the connection circuit is high.

[0058] It should be noted that in the embodiments of the present application, the high level and the low level are different logic levels with relative voltage values. When the voltage is between V1 and V2, it is a high level, and when the voltage is between V3 and V4, it is a low level, where V1 is not less than V4. For example, it can be predetermined that 0 to 0.25V is a low level, and 3.5V - 5V is a high level, but it is not limited thereto, and it can be determined according to the actual situation.

[0059] In some embodiments of the present application, as Figure 1As shown, the cigarette rod 12 further includes a motor 122. When the main control circuit 123 detects that the cartridge 11 and the cigarette rod 12 are in a combined state, it controls the motor 122 to work in a reminder mode, that is, the motor 122 vibrates after a time T1. For example, the motor 122 can be controlled to vibrate once every 0.5 s after the cartridge 11 and the cigarette rod 12 are in a combined state, and the vibration time is 40 ms. The vibration time and mode of the motor 122 are not limited to those described above and can be selected according to actual situations. Through the vibration of the motor 122, the user is informed and reminded that the cartridge 11 and the cigarette rod 12 are combined and can be used normally. It should be noted that both the motor 122 and the indicator light 126 belong to reminder devices and are used to remind the user in different modes that the electronic cigarette is working in different states. Among them, the reminder device can also include other reminder devices. For example, a display screen can be set in the electronic cigarette 10 to remind the user through icons, dynamic images, or text. In some embodiments of the present application, the reminder device further includes a speaker and a vibrator.

[0060] In some embodiments of the present application, the cartridge 11 further includes an authentication circuit 112. When the cartridge 11 and the cigarette rod 12 are in an uncombined state, the main control circuit 123 is not electrically connected to the authentication circuit 112. When the cartridge 11 and the cigarette rod 12 are in a combined state, the main control circuit 123 is electrically connected to the authentication circuit 112. The authentication circuit 112 includes a resistor representing the flavor information of the cartridge 11. When the cartridge 11 and the cigarette rod 12 are in a combined state, the above connection pin of the main control circuit 123 forms an electrical connection loop with the resistor. According to the different resistance values of this resistor in each cartridge 11, the main control circuit 123 determines the level of the connection pin corresponding to this resistor and determines the cartridges 11 of different flavors according to different levels. For example, when the resistor is 2 ohms, it represents that the cartridge 11 combined with the cigarette rod 12 is a grapefruit-flavored cartridge 11. When the resistor is 4 ohms, it represents that the cartridge 11 combined with the cigarette rod 12 is a mint-flavored cartridge 11. It should be noted that the specific resistance value and the corresponding flavor of the cartridge 11 are not limited thereto and can be determined according to actual situations.

[0061] In some embodiments of the present application, as Figure 1 shown, the cigarette rod 12 further includes an airflow sensor 121. The airflow sensor 121 is electrically connected to the main control circuit 123. In some embodiments of the present application, when the main control circuit 123 detects that the output level of the connection circuit is high, the airflow sensor 121 is activated. In some embodiments of the present application, when the main control circuit 123 detects that the output level of the connection circuit is low, the airflow sensor 121 is activated. Among them, activating the airflow sensor 121 can be to supply power to the airflow sensor 121 or to initialize the airflow sensor 121 so that the airflow sensor 121 is ready to perform normal detection operations.

[0062] In some embodiments of the present application, after the cartridge 11 and the rod 12 are in the combined state, the user can smoke normally. The airflow sensor 121 detects the change in airflow when the user makes a sucking action. When the airflow sensor 121 detects airflow, that is, when there is air flow or change, the airflow sensor 121 outputs a high level, indicating that the user is sucking. At this time, the main control circuit 123 controls the heating circuit 111 to heat and atomize the e-liquid. When the airflow sensor 121 does not detect airflow, that is, when there is no air flow or change, the airflow sensor 121 outputs a low level, indicating that the user has stopped sucking, and the main control circuit 123 controls the heating circuit 111 to stop heating. The main control circuit 123 records the starting time t2 when the high level is generated when detecting the change from low level to high level, and records the starting time t3 when the low level is generated when detecting the next change from high level to low level. The time T2 for the user to take a puff of smoke is T2 = t3 - t2, where t3 is greater than t2. When T2 is greater than the preset threshold t4, the main control circuit 123 counts and increases the count value C1, for example, it can be increased by 1. Where t4 can be set to 1s, but is not limited thereto. When the count value C1 within the preset time T3 is greater than the preset threshold n, the main control circuit 123 drives the motor 122 and the indicator light to work in a reminder mode. The reminder mode is: the motor 122 vibrates. For example, when the main control circuit 123 has a count value C1 greater than 15 within 10 minutes of T3, the main control circuit 123 can drive the motor 122 to vibrate once 1 s after the end of the 15th puff, and the vibration time is 40 ms, so as to effectively remind the user to control the smoking amount and prevent excessive smoking.

[0063] In some embodiments of the present application, the airflow sensor 121 may also output a low level when detecting airflow and output a high level when detecting no airflow. The main control circuit 123 can judge whether the user is smoking according to the level information with different logic levels output by the airflow sensor 121, and the specific judgment method is not limited to the above description.

[0064] In some embodiments of the present application, when T2 detected by the main control circuit 123 is greater than t5, the power supply of the battery 127 to the heating circuit 111 is disconnected, so that the heating circuit 111 stops heating. For example, when the control circuit 123 disconnects the power supply of the battery 127 to the heating circuit 111 when T2 is greater than 5 s, the heating circuit 111 stops heating. This can prevent the user from smoking excessively.

[0065] In some embodiments of the present application, such as Figure 1As shown, the cigarette rod 12 further includes a memory 124 and a wireless communication circuit 125, and both the memory 124 and the wireless communication circuit 125 are electrically connected to the main control circuit 123. The memory 124 can be used to store information and can be read from and written to. The memory 124 stores smoking information, which includes the ID of the cartridge 11, the number of puffs, the smoking time, and so on.

[0066] The wireless communication circuit 125 is used for wireless communication. The wireless communication can adopt one or more of the following modes: Bluetooth, Wi-Fi, 3G (the 3rd Generation), 4G (the 4th Generation), 5G (the 5th Generation), near-field communication, ultrasonic communication, ZigBee, RFID (Radio Frequency Identification), etc. The main control circuit 123 interacts with the intelligent terminal through the wireless communication circuit 125. The intelligent terminal includes a mobile phone, a computer, an intelligent wearable device (such as an intelligent watch), a tablet computer, etc.

[0067] In some embodiments of the present application, as Figure 3 shown, the cigarette rod 12 further includes an acceleration sensor 129, and the acceleration sensor 129 is electrically connected to the main control circuit 123. In some embodiments of the present application, when the main control circuit 123 detects that the output level of the connection circuit is high, the acceleration sensor 129 is started. In some embodiments of the present application, when the main control circuit 123 detects that the output level of the connection circuit is low, the airflow sensor 121 is started. Among them, starting the acceleration sensor 129 can be to supply power to the airflow sensor 121. It can also be to initialize the acceleration sensor 129 so that the acceleration sensor 129 is ready to perform normal detection operations.

[0068] In some embodiments of the present application, the main control circuit 123 obtains the acceleration information of the acceleration sensor 129, and starts the wireless communication circuit 125 when the acceleration value included in the acceleration information is greater than a preset threshold a1. The acceleration value includes at least one of the acceleration values in the X-axis direction, Y-axis direction, or Z-axis direction in the coordinate system. Among them, the acceleration sensor 129 is a G-sensor (gravity sensor), but is not limited thereto. Among them, the situation where the acceleration value is greater than the preset threshold a1 can indicate that the user is performing a shake operation on the electronic cigarette 10. For example, when the wireless communication circuit 125 includes a Bluetooth module and uses the Bluetooth module for wireless communication, the main control circuit 123 starts the Bluetooth module and sends a broadcast signal through the Bluetooth module when the obtained acceleration value is greater than the preset threshold a1. In addition, the main control circuit 123 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 increases. The fourth driving mode is: controlling the indicator light 126 to flash quickly 15 times to remind the user that the Bluetooth mode of the electronic cigarette 10 has been turned on. In addition, if the user performs a shake operation again, the indicator light 126 will flash quickly 15 times again. At this time, the user can perform Bluetooth pairing with the electronic cigarette 10 through the smart terminal and perform Bluetooth communication after the pairing is successful. The main control circuit 123 can send the smoking information stored in the memory 124 to the smart terminal through Bluetooth communication. The dedicated APP (Application) of the smart terminal performs data analysis based on the received smoking information to better guide the user to control smoking, replace smoking, quit smoking, etc.

[0069] In some embodiments of the present application, the authentication circuit 112 includes an encryption chip (not labeled in the figure). The encryption chip stores encrypted data information of the cartridge 11, and the data information includes a unique ID number, cartridge flavor, cartridge oil volume, etc. The main control circuit 123 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 11 and the cigarette rod 12 are in a combined state, and send a decryption success message after successful decryption and send a decryption failure message after decryption failure. After receiving the decryption failure message, the main control circuit 123 cuts off the power between the battery 127 and the heating circuit 111. If a decryption success message is received, the main control circuit 123 drives the indicator light 126 to flash quickly 3 times and drives the motor 122 to vibrate briefly 3 times. After successfully decrypting the encrypted data information obtained from the encryption chip, the main control circuit 123 starts the Bluetooth module to send a broadcast signal.

[0070] Figure 4Schematic diagram of the interaction principle between the electronic cigarette 10 and the smart terminal according to some embodiments of the present application. The smart terminal 201 turns on Bluetooth and matches with the electronic cigarette 10. After successful matching, it receives the data information sent by the electronic cigarette 10. The smart terminal 201 sends the above data information to the server 202. The server 202 is used to send the information about the electronic cigarette 10 that has been analyzed and processed to the smart terminal 201. The smart terminal 201 displays the data information of the cartridge 11 through a dedicated APP, including information such as cartridge flavor, daily puff count, weekly puff count, monthly puff count, cumulative puff count, remaining e-liquid volume, etc., and displays them as a curve chart. Among them, the remaining e-liquid volume can be calculated based on the cumulative puff count of the cartridge 11.

[0071] In some embodiments of the present application, when the electronic cigarette 10 and the smart terminal 201 are in a Bluetooth connection state, the "Stop Heating" touch control on the dedicated APP is activated by the user. The smart terminal 201 obtains the "Stop Heating" instruction and sends the "Stop Heating" instruction to the main control circuit 123 through the Bluetooth communication link. After receiving the "Stop Heating" instruction, the main control circuit 123 disconnects the power supply of the heating circuit 111 from the battery 127, and the heating circuit 111 stops heating. Even if the airflow sensor 121 detects airflow and outputs a high level, that is, the user takes a puff, the heating circuit 111 is not powered, that is, the heating circuit 111 cannot heat the e-liquid.

[0072] In some embodiments of the present application, the electronic cigarette 10 is also prohibited from being puffed in a no-smoking area. The smart terminal 201 has a positioning function. When the user enters the virtual geofence 301 with the smart terminal 201 and the electronic cigarette 10, as Figure 5 shown, the smart terminal 201 and the electronic cigarette 10 are in a Bluetooth connection state. The smart terminal 201 automatically receives the "Enter the Fence" notification. When the smart terminal 201 determines that the current location is within the geofence 301, that is, it belongs to the no-smoking area information, it sends a "No Smoking" instruction to the electronic cigarette 10. After receiving the "No Smoking" instruction, the main control circuit 123 of the electronic cigarette 10 switches to the "No Smoking" mode, that is, disconnects the electrical connection between the battery 127 and the heating circuit 111. The heating circuit 111 is prohibited from starting the heating function and does not respond to the level information output by the airflow sensor 121. That is to say, even if the airflow sensor 121 detects airflow and outputs a high level, that is, the user takes a puff, the heating circuit 111 is not powered, that is, the heating circuit 111 cannot heat the e-liquid. Therefore, even if the user takes a puff on the electronic cigarette 10 after entering the no-smoking area, the electronic cigarette 10 will not heat the e-liquid to form an atomized state, which can effectively prevent users from smoking illegally.

[0073] Among them, the geofence 301 can be a virtual geographical boundary defined by any geofence technology, such as an airport, a gas station, a shopping mall, etc. In addition, if the smart terminal 201 enters the geofence 301 and determines that the geofence 301 does not belong to a no-smoking area, the smart terminal 201 will not send a "no smoking" instruction to the electronic cigarette 10.

[0074] Specifically, as Figure 6 shown, the main control circuit 123 includes a switch 1231 and a switch 1232. The switch 1231 and the switch 1232 are connected in series and are arranged in the circuit between the battery 127 and the heating circuit 111. When both the switch 1231 and the switch 1232 are closed, the battery 127 can supply power to the heating circuit 111 normally, so that the heating circuit 111 heats the e-liquid. When at least one of the switch 1231 and the switch 1232 is open, the battery 127 and the heating circuit 111 are in an open circuit state, and the heating circuit 111 will not heat. In some embodiments of the present application, the main control circuit 123 controls the switch 1231 to close when no no-smoking instruction is received and it is detected that the current position does not belong to the first position information, and controls the switch 1232 to close when the output level of the connection circuit is high. The battery 127 supplies power to the cartridge 11 when both the switch 1231 and the switch 1232 are closed. In some embodiments of the present application, the main control circuit 123 controls the switch 1231 to close when no no-smoking instruction is received and it is detected that the current position does not belong to the first position information, and controls the switch 1232 to close when the output level of the connection circuit is low. The battery 127 supplies power to the cartridge 11 when both the switch 1231 and the switch 1232 are closed.

[0075] The main control circuit 123 controls the switch 1231 and the switch 1232 to close or open through the control pins of the switch 1231 and the switch 1232. Among them, the switch 1231 is default to be in a closed state. When the main control circuit 123 receives a "no smoking" instruction, it controls the switch 1231 to switch from the closed state to the open state, that is, the electronic cigarette 10 is switched to the "no smoking" mode. Even if the airflow sensor 121 detects airflow and outputs a high level, that is, the user sucks, the main control circuit 123 closes the switch 1232 according to the high-level signal, and the battery 127 and the heating circuit 111 are still in an open circuit state. At this time, the heating circuit 111 will not heat.

[0076] When the main control circuit 123 does not receive the "no smoking" instruction, the switch 1231 is in the closed state. When the airflow sensor 121 detects airflow and outputs a high level, that is, when the user sucks, the main control circuit 123 closes the switch 1232 according to this high-level signal. At this time, since both the switch 1231 and the switch 1232 are closed, the battery 127 can supply power to the heating circuit 111 normally, so that the heating circuit 111 heats the e-liquid, and the user can suck the electronic cigarette 10 normally.

[0077] As Figure 7 shown, when the smart terminal 201 and the electronic cigarette 10 leave the geographical fence 301 belonging to the no-smoking area, after the smart terminal 201 automatically receives the "leave the fence" notification, it sends the "allow smoking" instruction to the electronic cigarette 10. After the main control circuit 123 of the electronic cigarette 10 receives the "allow smoking" instruction, it switches to the "allow smoking" mode. That is, when the main control circuit 123 switches to the "allow smoking" mode, the airflow sensor 121 detects airflow and outputs a high level, which means that the user is sucking, and the main control circuit 123 controls the heating circuit 111 to heat the e-liquid to atomize the e-liquid.

[0078] Specifically, as Figure 8 shown, after the main control circuit 123 receives the "allow smoking" instruction, it switches the switch 1231 from the open state to the closed state, that is, the electronic cigarette 10 is switched to the "allow smoking" mode. At this time, when the airflow sensor 121 detects airflow and outputs a high level, which means that the user is sucking normally, the main control circuit 123 switches the switch 1232 to the closed state according to this high-level signal. Since both the switch 1231 and the switch 1232 are in the closed state, the battery 127 supplies power to the heating circuit normally, so that the heating circuit 111 heats the e-liquid to form an atomized state, and the user can suck the electronic cigarette 10 normally.

[0079] Figure 9 The block diagram of the principle of the electronic cigarette 10 according to some embodiments of the present application is shown. The cigarette rod 12 further includes a positioning module 130. The positioning module 130 is electrically connected to the main control circuit 123. The positioning module 130 has a positioning function and is used to obtain position information. The positioning module 130 includes a GPS (Global Positioning System) positioning module, a Beidou positioning module, or a GLONASS (Global Navigation Satellite System) positioning module, etc.

[0080] In some embodiments of the present application, when the user carries the electronic cigarette 10 as Figure 9 shown into the geographical fence 301, as Figure 10AAs shown, after the electronic cigarette 10 automatically receives the "enter the fence" notification sent by the geofence 301 through the wireless communication circuit 125, when the main control circuit 123 determines that the current location is within the geofence 301, that is, it belongs to the no-smoking area information, the heating circuit 111 is prohibited from heating. Even if the airflow sensor 121 detects airflow and outputs a high level, that is, the user is sucking, the heating circuit 111 is not powered, that is, the heating circuit 111 cannot heat the e-liquid.

[0081] Return to Figure 6 , where the switch 1231 is default to be in the closed state. When the main control circuit 123 determines that the current location is within the geofence 301, that is, it belongs to the no-smoking area, it controls the switch 1231 to switch from the closed state to the open state, that is, the electronic cigarette 10 is switched to the "no-smoking allowed" mode. Even if the airflow sensor 121 detects airflow and outputs a high level, that is, the user is sucking, the main control circuit 123 closes the switch 1232 according to this high-level signal, but the battery 127 and the heating circuit 111 are still in an open circuit state, and at this time the heating circuit 111 will not heat.

[0082] When the main control circuit 123 determines that the current location is outside the geofence 301, that is, it does not belong to the no-smoking area, it keeps the switch 1231 in the closed state. When the airflow sensor 121 detects airflow and outputs a high level, that is, the user is sucking, the main control circuit 123 closes the switch 1232 according to this high-level signal. At this time, since both the switch 1231 and the switch 1232 are closed, the battery 127 will normally supply power to the heating circuit 111, enabling the heating circuit 111 to heat the e-liquid, and the user can normally suck the electronic cigarette 10.

[0083] When the user carries the electronic cigarette 10 as shown in Figure 9 and leaves the geofence 301 that belongs to the no-smoking area, as shown in Figure 10B , after the electronic cigarette 10 automatically receives the "leave the fence" notification sent by 301 through the wireless communication circuit 125, the main control circuit 123 switches to the "smoking allowed" mode. That is, when the main control circuit 123 switches to the "smoking allowed" mode, if the airflow sensor 121 detects airflow and outputs a high level, it means the user is sucking, and the main control circuit 123 controls the heating circuit 111 to heat the e-liquid to atomize the e-liquid.

[0084] Return to Figure 8, after the main control circuit 123 receives the "leave the fence" notification, it switches the switch 1231 from the off state to the on state, that is, the electronic cigarette 10 is switched to the "allowed to smoke" mode. At this time, when the airflow sensor 121 detects airflow and outputs a high level, it means that the user is performing normal suction. The main control circuit 123 switches the switch 1232 to the on state according to this high-level signal. Since both the switch 1231 and the switch 1232 are in the on state, the battery 127 supplies power to the heating circuit normally, so that the heating circuit 111 heats the e-liquid to form an atomized state, and the user can normally suck the electronic cigarette 10.

[0085] Figure 11 It is a flowchart of the operation method of some embodiments of the application. Figure 11 The operation method in is used for the electronic cigarette 10 in one or more of the above embodiments.

[0086] In step 1101, the main control circuit 123 detects the output level of the connection circuit. This connection circuit is a circuit used to connect with the cartridge 11. Since the cartridge 11 has its own resistance, when the cartridge 11 is inserted into the cigarette rod 12 and combined with the cigarette rod 12, the cartridge 11 will generate a voltage division in this connection circuit. Whether the cartridge 11 and the cigarette rod 12 are combined can be determined according to the output level of this connection circuit.

[0087] In step 1102, it is judged whether the output level is a low level? If so, go to step 1103; if not, it means that the cartridge 11 and the cigarette rod 12 are not combined, so return to step 1101, and the main control circuit 123 continuously detects the output level of the connection circuit.

[0088] In step 1103, the main control circuit 123 drives the indicator light 126 and the motor 122 to work in a reminder mode. This reminder mode is: the indicator light 126 lights up and then gradually goes out after the cartridge 11 and the cigarette rod 12 are combined; and, the cartridge 11 and the cigarette rod 12 vibrate once 0.5 s after being combined, and the vibration time is 40 ms. Among them, the reminder mode is not limited to this and can be set according to the actual situation. In this way, the user can be reminded that the cartridge 11 and the cigarette rod 12 have been combined and can be used normally.

[0089] Figure 12 It is a flowchart of the operation method of some embodiments of the present application. Figure 12 The operation method in can be used for the electronic cigarette 10 in one or more of the above embodiments.

[0090] In step 1201, the main control circuit 123 detects whether the cartridge 11 and the cigarette rod 12 are combined. If so, go to step 1202; if not, continue to detect.

[0091] In step 1202, the main control circuit 123 obtains the suction time T2 of each puff of the user. Specifically, when the airflow sensor 121 detects airflow, the airflow sensor 121 outputs a high level, indicating that the user is puffing. At this time, the main control circuit 123 controls the heating circuit 111 to heat and atomize the e-liquid. When the airflow sensor 121 does not detect airflow, the airflow sensor 121 outputs a low level, indicating that the user has stopped puffing, and the main control circuit 123 controls the heating circuit 111 to stop heating. The main control circuit 123 records the starting moment t2 when the high level is generated when detecting the change from low level to high level, and records the starting moment t3 when the low level is generated when detecting the change from high level to low level. The suction time T2 of each puff of the user = t3 - t2, where t3 is greater than t2.

[0092] In step 1203, the main control circuit 123 detects whether the suction time T2 of each puff of the user is greater than a preset threshold t4. If so, it proceeds to step 1204. If not, it proceeds to step 1205 to keep the puff count C1 unchanged.

[0093] In step 1204, the puff count C1 is incremented by 1. In step 1205, the puff count C1 remains unchanged.

[0094] In step 1206, the main control circuit 123 determines whether the puff count C1 within the suction time T3 is greater than a preset threshold n. If C1 is greater than n, it proceeds to step 1207; if C1 is less than n, it returns to step 1202.

[0095] In step 1207, the main control circuit 123 drives the motor 122 to operate in a reminder mode. The reminder mode is: the motor 122 vibrates once, and the vibration time is 40 ms. It should be noted that the reminder mode is not limited to this. In this way, it can remind the user to control the smoking amount and prevent excessive puffing.

[0096] Figure 13 It is a flowchart of the operation method of some embodiments of this application. Figure 13 The operation method in can be used for the electronic cigarette 10 in one or more of the above embodiments.

[0097] In step 1301, the main control circuit 123 obtains the acceleration value of the acceleration sensor 129. The acceleration value can include at least one of the acceleration values in the X-axis direction, Y-axis direction, or Z-axis direction in the coordinate system. The acceleration sensor 129 is a G-sensor (gravity sensor), but it is not limited to this.

[0098] In step 1302, the main control circuit 123 determines whether the obtained acceleration value is greater than a preset threshold. If so, it indicates that the user is performing a shaking action on the cigarette rod 12, and the process proceeds to step 1303; if not, the process returns to step 1301.

[0099] In step 1303, the main control circuit 123 activates the wireless communication circuit 125 to send a wireless signal and drives the indicator light 126 to work in a reminder mode.

[0100] Specifically, the wireless communication circuit 125 may include a Bluetooth module. When using the Bluetooth module for wireless communication, when the acceleration value obtained by the main control circuit 123 is greater than the preset threshold, the Bluetooth module is activated, and a broadcast signal is sent through the Bluetooth module. In addition, the third indicator light 126 flashes quickly 15 times to remind the user that the Bluetooth mode of the electronic cigarette 10 has been turned on. In addition, if the user performs a shaking action again, the indicator light 126 will flash quickly 15 times again.

[0101] Figure 14 and Figure 16 is an exploded structural schematic diagram of the cartridge 11 of some embodiments of the present application. The cartridge 11 includes a heating component 146, a thimble 1471, a thimble 1472, a shrapnel 1481, a shrapnel 1482, and a PCB (Printed Circuit Board) module 151. In some embodiments, the heating component 146, the thimble 1471, the thimble 1472, the shrapnel 1481, the shrapnel 1482, and the PCB module 151 form a heating circuit 111 in some embodiments of the present application. In some embodiments, the heating component 146, the thimble 1471, the thimble 1472, the shrapnel 1481, the shrapnel 1482, and the PCB module 151 form a heating circuit 111 and an authentication circuit 112 in some embodiments of the present application, wherein a resistor (not shown in the figure) representing the flavor information of the cartridge 11 is provided on the PCB module 151.

The cigarette rod 12 includes a cartridge pin 1621, a cartridge pin 1622, a cartridge pin 1623, a main control module 166, a motor 122, a battery 127, a charging module 128, and an antenna 170. Among them, the main control module 166 and the antenna 170 are composed of a main control circuit 123, a memory 124, a wireless communication circuit 125, and an indicator light 126 in some embodiments of the present application. In some embodiments of the present application, the cartridge pins 1621, 1622, and 1623 all serve as pins for electrical connection and can also be referred to as pins 1621, 1622, and 1623. In some embodiments, the cartridge pins 1621 and 1622 can be used as external power supply pins, and the cartridge pin 1623 can be used as an external data pin.

[0103] Among them, Figure 14 the disassembled cartridge 11 in Figure 15 and the disassembled cigarette rod 12 in Figure 2B can form the combined electronic cigarette 10 as shown in Figure 16 after installation and combination. The disassembled cartridge 11 in Figure 17 and the disassembled cigarette rod 12 in Figure 2B can form the combined electronic cigarette 10 as shown in

[0104] Figure 18 Partial cross-sectional structural schematic diagram of the electronic cigarette of some embodiments of the present application. The cartridge 11 is inserted into the cigarette rod 12, and the cartridge 11 and the cigarette rod 12 are in a combined state, as shown in Figure 2B . The heating component 146 includes pins 1461 and 1462. The pins 1461, the thimble 1471, and the shrapnel 1481 are electrically connected to the cartridge pin 1621 through the PCB module 151; the pins 1462, the thimble 1472, and the shrapnel 1482 are electrically connected to the cartridge pin 1622 through the PCB module 151, as shown in Figures 14 - 17 . The cartridge pins 1621, 1622, and 1623 are all electrically connected to the main control module 166. When the cartridge 11 and the cigarette rod 12 are not combined, as shown in Figure 2A , the cartridge pins 1621, 1622, and 1623 are not in contact with the PCB module 151. Among them, the pins 1461, 1462, the thimbles 1471, 1472, the shrapnels 1481, 1482, the cartridge pins 1621, and 1622 are all made of conductive materials. In some embodiments, the pins 1462 and 1462 can be used as the positive electrode and the negative electrode respectively. In some embodiments, the pins 1462 and 1462 can be used as the negative electrode and the positive electrode respectively.

[0105] The cartridge 11 further includes a tube body 143, a heating base 150, and a bottom cover 154. The tube body 143 includes an upper tube body 1431 and a lower tube body 1432. The bottom cover 154 is covered on the bottom of the lower tube body 1432 and is fixedly connected to the lower tube body 1432 through a locking structure. Among them, the upper tube body 1431 is the upper part of the tube body 143, and the lower tube body 1432 is the lower part of the tube body 143. The heating base 150 is disposed in the lower tube body 1432 and on the bottom cover 154. Among them, the PCB module 151 is disposed in the lower tube body 1432 and between the heating base 150 and the bottom cover 154. Among them, the elastic pieces 1481 and 1482, the ejector pins 1471 and 1472, and the heating component 146 are sequentially arranged in the heating base 150. The elastic pieces 1481 and 1482 are in electrical contact with two contact pads at the upper end of the PCB module 151. Among them, the two contact pads at the upper end of the PCB module 151 are electrically connected to the contact pads 1511 and 1512 at the lower end through the circuit or lead inside the PCB module 151. The ejector pins 1471 and 1472 respectively pass through the through holes 1501 and 1502 at the bottom of the heating base 150 and are in contact with the elastic pieces 1481 and 1482. Among them, the pins 1461 and 1462 of the heating component 146 are respectively accommodated in the cavities of the ejector pins 1471 and 1472 and can form electrical contact with the ejector pins 1471 and 1472. In some embodiments of the present application, the ejector pin has a needle tube and a needle base. The needle tube of the ejector pin 1471 is used to accommodate the pin 1461 and is in electrical contact. The needle tube of the ejector pin 1472 is used to accommodate the pin 1462 and is in electrical contact. The needle bases of the ejector pins 1471 and 1472 are respectively in electrical contact with two contact pads at the upper end of the PCB module 151.

[0106] Figure 19 It is a schematic bottom view structure diagram of the cartridge 11 in some embodiments of the present application. As Figure 19As shown, the lower end of the PCB module 151 further includes contact pads 1511, 1512, and 1513. The contact pads 1511, 1512, and 1513 are located in the through holes 1542 of the bottom cover 154 so that when the cartridge 11 and the smoking rod 12 are combined, the contact pads 1511, 1512, and 1513 are in electrical contact with the cartridge pins 1621, 1622, and 1623 respectively. In some embodiments, the contact pads 1511, 1512, and 1513 are integrated into the PCB module 151. In some embodiments, when the cartridge 11 contacts the cartridge pins of the smoking rod through the contact pads, since the cartridge itself has resistance, a voltage or current change will be generated between the cartridge pins 1621 and 1622, that is, the main control module 166 will detect the output level value of the connection circuit where the cartridge pins 1621 and 1622 are located. For example, in some embodiments, when in electrical contact, the output level value is a high level. In some embodiments, in a point contact mode, the output level is a low level.

[0107] In some embodiments of the present application, the cartridge 11 further includes an oil absorption pad 149. The oil absorption pad 149 can be used to absorb the possibly leaked e-liquid. The material of the oil absorption pad 149 is cotton, but it can be selected according to the actual situation and is not limited thereto. Through holes or openings are provided on both sides of the oil absorption pad 149, and the through holes or openings can cover the outer walls of the upper halves of the thimble 1471 and the thimble 1472.

[0108] Figures 20A - 20B It is a schematic structural diagram of the heating base 150 of some embodiments of the present application. The heating base 150 includes a base body (not marked in the figure), a first side end structure, and a second side end structure. Through holes 1501 and 1502 are provided on the base body. The first side end structure and the second side end structure are respectively located on opposite sides of the base. The heating base 150 includes a side end cavity 1503, one or more through holes 1504, and a side end opening 1505. Among them, the side end cavity 1503 is provided in the first side end structure, and the side end opening 1505 is provided in the second side end structure. One or more through holes 1504 are provided on the side of the side end cavity 1503 close to the side end opening 1505. Among them, the side end opening 1505 connects the space in the air flow channel 1433 of the pipe body 143 with the space between the heating main body 1464 and the oil absorption pad 149 to be used as a part of the channel for smoke and air flow in the cartridge 11.

[0109] In some embodiments of the present application, the cartridge 11 further includes an air tube 152. The air tube 152 is disposed between the heating base 150 and the bottom cover 154. The upper end opening of the air tube 152 is located in the side cavity 1503 of the heating base 150. One or more through holes 1504 penetrate the space between the upper port of the air tube 152 and the inside of the heating base 150. The lower port of the air tube 152 is disposed in the bottom cover 154 and is exposed by the through hole 1541, and is slightly lower than the outer surface of the bottom cover 154 or flush with the outer surface of the bottom cover 154. The lower port of the air tube 152 communicates with the space outside the cartridge 11. In some embodiments of the present application, the heating base 150 further includes a ramp structure 1506. The ramp structure 1506 is located at the bottom of the heating base 150 and forms part of the side opening 1505. During the user's inhalation, the ramp structure 1506 can prevent e-liquid from entering the left air flow channel 1433 in the tube body 143.

[0110] In some embodiments of the present application, the height of one or more through holes 1504 from the bottom cover 154 is greater than the height of the oil absorption pad 149 from the bottom cover 154. In this way, even if there may be leakage, it will be absorbed by the oil absorption pad 149 first and will not leak outside the cartridge 11 through the air tube 152, improving the user experience. In some embodiments, the height of the upper port of the air tube 152 from the bottom cover 154 is greater than the height of one or more through holes 1504 from the bottom cover 154. In this way, it can be ensured that even if there is leakage in the cartridge 11 and when the e-liquid overflows to one or more through holes 1504, it can flow out through one or more through holes 1504 and still be retained in the cartridge 11, rather than overflowing outside the cartridge 11 through the upper port of the air tube 152, improving the user experience. In some embodiments, the material of the air tube 152 is steel, but it is not limited thereto.

[0111] In some embodiments of the present application, the cartridge 11 further includes an O-ring 153. The O-ring 153 is disposed around the outer wall of the heating base 150. In some embodiments of the present application, a groove is provided on the outer wall of the base body of the heating base 150. The groove is an annular groove 1507, as Figure 20A and 20B shown. The O-ring 153 is nested in the annular groove 1507 to seal the outer wall of the heating base 150 and the inner wall of the tube body 143 to prevent e-liquid from leaking outside the cartridge 11.

[0112] In some embodiments of the present application, the cartridge 11 further includes a heating top cover 144 and a heating silica gel body 145. The tube body 143 further includes a storage chamber 1434. The heating top cover 144 and the heating silica gel body 145 both have a number of through holes (not labeled in the figure). The e-liquid stored in the storage chamber 1434 penetrates through the through holes in the heating top cover 144 and the through holes in the heating silica gel body 145 to contact the heating component 146. When the heating component 146 is powered on and heated, the temperature generated by the heating component 146 will atomize the e-liquid in contact with it. According to the viscosity of the e-liquid, by adjusting the shape, size and quantity of the through holes in the heating top cover 144 and the heating silica gel body 145, the heating component 146 can be effectively contacted with the e-liquid to avoid dry burning and the generation of burnt smell.

[0113] Figures 21A - 21C It is a schematic structural diagram of the heating component in some embodiments of the present application. The heating component 146 includes pins 1461, pins 1462, a heating element 1463 and a heating body 1464. The pins 1461, the pins 1462 and the heating element 1463 are all arranged in the heating body 1464. In some embodiments, the heating element 1463 can be printed on the bottom surface of the heating body 1464 via circuit printing technology. A groove 1465 is also provided in the heating body 1464. As described above, the e-liquid in the storage chamber 1434 penetrates through the through holes in the heating top cover 144 and the heating silica gel body 145 and enters the surface of the groove 1465 in the heating component 146 to contact the heating body 1464. The pins 1461, the heating element 1463 and the pins 1462 are electrically connected in sequence. When the pins 1461 and the pins 1462 are powered, the heating element 1463 generates heat to increase the temperature of the heating body 1464, and after the temperature rises to a critical value higher than that for atomizing the e-liquid, the e-liquid in contact with the heating body 1464 is atomized.

[0114] In some embodiments of the present application, the heating element 1463 can be printed inside the heating body 1464 via circuit printing technology. In this way, damage to the heating element 1463 that may occur during subsequent assembly can be avoided. The heating element 1463 can include a metal material. In certain embodiments, the heating element 1463 can include silver. In certain embodiments, the heating element 1463 can include platinum. In certain embodiments, the heating element 1463 can include palladium. In certain embodiments, the heating element 1463 can include a nickel alloy material. The material included in the heating element 1463 is not limited to the above, and can be selected according to actual situations.

[0115] In some embodiments of the present application, the heating element 1463 can be printed on the bottom surface of the groove 1465 in the heating body 1464 via circuit printing technology.

[0116] In some embodiments of the present application, the heating body 1464 may be made of a ceramic material, and the heating body 1464 may include a diatomite material.

The material included in the heating body 1464 is not limited to those described above and can be selected according to actual situations.

[0117] The heating body 1464 may have a self-limiting temperature characteristic. The resistance value of the heating body 1464 may increase as the temperature rises. When the temperature of the heating body 1464 reaches a critical value CV1, it has a resistance value R1. In certain embodiments, when the temperature of the heating body 1464 reaches a critical value CV1, the heating element 1463 can no longer raise the temperature of the heating body 1464. In certain embodiments, when the resistance value of the heating body 1464 reaches R1, the heating power output by the heating element 1463 can no longer raise the temperature of the heating body 1464.

[0120] The self-limiting temperature characteristic of the heating body 1464 can prevent the heating component 146 from dry burning and continuously increase the temperature when powered on.

The self-limiting temperature characteristic of the heating body 1464 can increase the safety of the electronic cigarette 10. The self-limiting temperature characteristic of the heating body 1464 can improve the service life of the electronic cigarette 10.

[0121] As Figure 21C shown, the heating body 1464 may have pores. In some embodiments, the pore shape may be square. In some embodiments, the pore shape may be cylindrical. In some embodiments, the pore shape may be annular. In some embodiments, the pore shape may be hexagonal columnar, as Figure 21D shown in the enlarged structural schematic diagram of the A position of the heating body 1464.

[0124] Figure 22 This is a structural schematic diagram of a heating component according to some embodiments of the present application. The heating component 146 further includes a protection element 1466. The protection element 1466 is disposed in the heating body 1464 and coupled between the pin 1461, the heating element 1463 and the pin 1462 to form a series circuit. Among them, the protection element 1466 has a self-recovery characteristic. In some embodiments, the protection element 1466 is a fuse with a self-recovery characteristic, that is, a self-recovery fuse. The protection element 1466 can be disposed at either end or both ends of the heating element 1463. Among them, the protection element 1466 can be formed integrally through high-temperature sintering and shaping during the manufacturing process of the heating component 146.

[0125] When the temperature of the protection component 1466 rises to a critical value CV2, the protection component 1466 forms an open circuit, so that the series circuit formed by the pin 1461, the heating element 1463, the protection component 1466, and the pin 1462 is broken, that is, the heating element 1463 stops heating. When the temperature of the protection component 1466 drops to a critical value CV3, the protection component 1466 forms a short circuit, so that the series circuit formed by the pin 1461, the heating element 1463, the protection component 1466, and the pin 1462 forms a path, and then the heating element 1463 starts heating.

[0126] In some embodiments, the critical value CV3 can be the same as the critical value CV2. In some embodiments, the critical value CV3 can be different from the critical value CV2. In some embodiments, the critical value CV3 is lower than the critical value CV2.

[0127] In some embodiments, the critical value CV2 is in the range of 200°C to 220°C. In some embodiments, the critical value CV2 is in the range of 220°C to 240°C. In some embodiments, the critical value CV2 is in the range of 240°C to 260°C. In some embodiments, the critical value CV2 is in the range of 260°C to 280°C. In some embodiments, the critical value CV2 is in the range of 280°C to 300°C. In some embodiments, the critical value CV2 is in the range of 300°C to 320°C.

[0128] In some embodiments, the critical value CV3 is in the range of 180°C to 200°C. In some embodiments, the critical value CV3 is in the range of 200°C to 220°C. In some embodiments, the critical value CV3 is in the range of 220°C to 240°C. In some embodiments, the critical value CV3 is in the range of 240°C to 260°C. In some embodiments, the critical value CV3 is in the range of 260°C to 280°C. In some embodiments, the critical value CV3 is in the range of 280°C to 300°C.

[0129] In some embodiments of the present application, the protection component 1466 has a non-recoverable characteristic, such as a fuse with a non-recoverable characteristic. When the temperature of the protection component 1466 rises to a critical value CV4, the protection component 1466 forms an open circuit. In certain embodiments, the protection component 1466 that forms an open circuit does not form a short circuit due to a temperature drop.

[0130] The protection component 1466 can prevent the heating element 1463 from dry burning. The protection component 1466 can reduce the probability of the electronic cigarette 10 burning out. The protection component 1466 can increase the safety of the electronic cigarette 10. The protection component 1466 can improve the service life of the electronic cigarette 10.

[0131] In some embodiments of the present application, the cartridge 11 further includes a mouthpiece 141 and a cap 142. Among them, the cap 142 is sleeved on a part of the upper tube body 1431. When the user sucks the electronic cigarette 10, the cap 142 contacts the user's mouth. The material of the cap 142 is silicone, but it is not limited thereto. The mouthpiece 141 covers the entire cap 142 and is sleeved on most of the upper tube body 1431. Through holes for air outlet are provided on both the upper tube body 1431 and the cap 142. The positions of these through holes roughly correspond to each other so as to be able to send the atomized smoke into the user's mouth.

[0132] In some embodiments of the present application, the cigarette rod 12 includes a battery holder cover 161, a housing 171, and a battery holder 169. Among them, the battery holder 169 is installed inside the housing 171, and the battery holder cover 161 is installed at the upper end of the battery holder 169 so as to form an accommodating space inside the housing 171 above the battery holder cover 161. This accommodating space is used to accommodate the lower tube body 1432 of the cartridge 11, and the upper tube body 1431 of the cartridge 11 is located outside the housing 171. In some embodiments of the present application, the structure at the junction of the upper tube body 1431 and the lower tube body 1432 matches the structure of the upper end of the housing 171. The upper end of the battery holder 169 has through holes for accommodating the needle pins 1621, 1622, and 1623, and through holes for air circulation. The cigarette rod 12 further includes magnets 1631 and 1632. Through holes for installing the magnets 1631 and 1632 are also provided at the upper end of the battery holder 169. Among them, the needle pins 1621, 1622, and 1623 are located between the magnets 1631 and 1632.

[0133] Figure 23 It is a schematic top view structure of the cigarette rod 12 in some embodiments of the present application. The battery holder cover 161 has a structure corresponding to the upper end of the battery holder 169. As Figure 23As shown in the figure, through holes 1611, 1612, 1613, 1614, 1615, and 1616 are provided on the battery bracket cover 161. Among them, the spring pins 1621, 1622, and 1623 extend out through the through holes 1611, 1612, and 1613 respectively. The magnets 1631 and 1632 are located in the through holes 1615 and 1616 respectively. In some embodiments, the tops of the magnets 1631 and 1632 are flush with the cover surface of the battery bracket cover 161. In some embodiments, the tops of the magnets 1631 and 1632 are slightly lower than the cover surface of the battery bracket cover 161. In some embodiments, the tops of the magnets 1631 and 1632 are slightly higher than the cover surface of the battery bracket cover 161. The magnets 1631 and 1632 are used to firmly suck the cartridge 11 and the smoking rod 12 together by magnetic force when the cartridge 11 and the smoking rod 12 are combined, preventing the cartridge 11 or the smoking rod 12 from slipping when the user smokes the electronic cigarette 10, thus improving the user experience. In addition, the through hole 1614 is used to communicate the air flow detection port of the air flow sensor 121 inside the smoking rod 12 with the external space.

[0134] After the battery bracket cover 161 covers the upper end of the battery bracket 169, the spring pins 1621, 1622, and 1623 can respectively contact the contact pads 1511, 1512, and 1513 at the lower end of the PCB module 151 in the cartridge 11, so that the spring pins 1621, 1622, and 1623 are all electrically connected to the main control module 166. The main control module 166, the battery 127, the charging circuit 128, the motor 122, and the air flow sensor 121 are all installed in the corresponding structures in the battery bracket 169, and the battery 127, the charging circuit 128, the motor 122, and the air flow sensor 121 are all electrically connected to the main control module 166.

[0135] In some embodiments of the present application, the smoking rod 12 further includes a silica gel sleeve 167. The silica gel sleeve 167 is used to protect the air flow sensor 121. The smoking rod 12 further includes a light guide column bracket 165. The light guide column bracket 165 is disposed on the battery bracket 169 and is located on one side of the main control module 166. Among them, the indicator light 126 is disposed on the main control module 166 and is located in the space between the main control module 166 and the light guide column bracket 165. When the indicator light 126 is on, the light information can be displayed to the user through the light guide column bracket 165 and the through hole in the housing 171.

[0136] In some embodiments of the present application, the battery 127 is located between the main control module 166 and the charging circuit 128, and the charging circuit 128 is fixed to the battery holder 169 by screws 168. The cigarette rod 12 further includes an antenna 170 for receiving and transmitting wireless signals. The antenna 170 is disposed in the space between one side of the battery 127 and the outer shell 171, and the antenna 170 is electrically connected to the main control module 166. In some embodiments of the present application, the cigarette rod 12 further includes a sponge pad 164, and the sponge pad 164 is disposed in the space between the other side of the battery 127 opposite to the antenna 170 and the inner wall of the outer shell 171. Wherein, the sponge pad 164 contacts the battery 127 and the inner wall of the outer shell 171 to provide a buffering force. When the cartridge 11 is combined with the cigarette rod 12, the accommodation space in the outer shell 171 accommodates the lower tube body 1432 and the bottom cover 154 in the cartridge 11.

[0137] In some embodiments of the present application, when the cartridge 11 is not combined with the cigarette rod 12, the through hole 1614 for air circulation in the battery holder cover 161 of the cigarette rod 12 can communicate the external air with the air flow detection through hole of the air flow sensor 121.

[0138] Figure 24 Schematic diagram of the air flow channel structure of the electronic cigarette 10 according to some embodiments of the present application. As Figure 24 shown, after the cartridge 11 is combined with the cigarette rod 12, there is a gap between the outer side wall of the lower tube body 1432 of the cartridge 11 and the inner side wall of the outer shell 171 of the cigarette rod 12, and there is also a gap for air circulation between the bottom cover 154 of the cartridge 11 and the battery holder cover 161 of the cigarette rod 12, and enters the air flow detection through hole of the air flow sensor 121 through the through hole 1614 for air circulation of the battery holder cover 161, so as to form an air flow channel f1 that penetrates the external air of the electronic cigarette 10 and the air flow sensor 121 of the electronic cigarette. Thereby, it is ensured that the external air of the electronic cigarette 10 can effectively enter.

[0139] When the cartridge 11 of the electronic cigarette 10 is combined with the cigarette rod 12 and the user performs a suction action, when the air flow at the air flow detection through hole of the air flow sensor 121 enters the gap between the bottom cover 154 and the battery holder cover 161 through the through hole 1614 at the battery holder cover 161, that is, when the air flow, namely the air flow, is detected, a high level is output. The main control module 166 causes the battery 127 to supply power to the heating component 146, and the heating component 146 heats the e-liquid. Subsequently, air enters the space between the heating component 146 and the oil absorption pad 419 through the air pipe 152 and one or more through holes 1504. At this time, part of the e-liquid is atomized by heating up. The air flow brings the smoke formed by atomizing the e-liquid through the side end opening 1505 into the air flow channel 1433, and enters the user's mouth through the corresponding through holes on the upper tube body 1431 and the cap 142. Thus, an air flow channel f2 is formed to realize a smoking action. It should be noted that during the suction process, air will also enter the air pipe 152 through the air flow channel f1.

[0140] In some embodiments of the present application, return to Figure 2A , when the cartridge 11 is not inserted into the cigarette rod 12, there is no load between the cartridge pins 1621 and 1622, and the main control module 166 detects a high level between the cartridge pins 1621 and 1622. As Figure 2B shown, when the cartridge 11 is inserted into the cigarette rod 12, the cartridge pins 1621 and 1622 are electrically connected to the contact pads of the PCB module 151, that is, the PCB module 151 forms a current loop with the cartridge pins 1621 and 1622 as a load. At this time, since the PCB module 151 can divide the voltage as a load, the main control module 166 detects a low level between the cartridge pins 1621 and 1622. At this time, the main control module 166 drives the indicator light 126 and the motor 122 to work in a reminder mode. The reminder mode is: the indicator light 126 lights up and gradually goes out after the cartridge 11 and the cigarette rod 12 are combined; and, the cartridge 11 and the cigarette rod 12 vibrate once 0.5 s after being combined, and the vibration time is 40 ms. Among them, the reminder mode is not limited to this and can be set according to the actual situation. In this way, the user can be reminded that the cartridge 11 and the cigarette rod 12 have been combined and can be used normally. In some embodiments of the present application, the main control module 166 can also confirm that the cartridge 11 and the cigarette rod 12 are not combined when detecting that the connection circuit formed by the cartridge pins 1621 and 1622 of the cigarette rod 12 outputs a low level, and confirm that the cartridge 11 and the cigarette rod 12 have been combined when detecting that the connection circuit outputs a high level.

[0141] When the user confirms that the cartridge 11 has been combined according to the prompts of the indicator light 126 and the motor 122, the user starts to perform a normal suction action.

[0142] When the user does not perform an inhalation action, the airflow sensor 121 does not detect a change in airflow, and the airflow sensor 121 outputs a low level. When the user performs an inhalation action, the airflow sensor 121 detects the airflow, and the output level of the airflow sensor 121 changes from low level to high level. When the main control module 166 receives the signal that the airflow sensor 121 changes from low level to high level, it outputs a voltage through the spring pins 1621 and 1622, and provides the output voltage to the heating component 146 through the contact pads of the PCB module 151, the shrapnel 1481 and 1482, and the thimble 1471 and 1472, so that the heating component 146 heats up and atomizes the e-liquid in contact with the heating component 146. At the same time, when the user smokes, air enters the cartridge 11 through the trachea 152 and sends the atomized smoke into the user's mouth through the airflow channel, thus completing a smoking action. When this smoking action stops, the airflow change in the electronic cigarette 10 stops, the airflow sensor 121 does not detect the airflow change, and the output level of the airflow sensor 121 changes from high level to low level. At this time, after the main control module 166 obtains that the output level changes from high level to low level, it controls to disconnect the output voltage between the spring pins 1621 and 1622, that is, stops heating the heating component 146. The main control module 166 records the start time t2 when the high level is generated when detecting that the output level of the airflow sensor 121 changes from low level to high level, and records the start time t3 of this low level when detecting the next time the output level of the airflow sensor 121 changes from high level to low level. Among them, the time T2 for the user to take a puff of smoke = t3 - t2, where t3 is greater than t2. When T2 is greater than the preset threshold t4, the main control module 166 counts and increases the count value C1 by 1, for example. Among them, t4 can be set to 1s, but it is not limited thereto. If the user keeps performing the inhalation action, when the count value C1 of the main control module 166 within the time T3 is greater than the preset threshold n, the drive motor 122 works in a reminder mode. This reminder mode is: the motor 122 vibrates. For example, when the count value C1 of the main control module 166 within T3 of 10 minutes is greater than 15, the main control module 166 can drive the motor 122 to vibrate briefly once 1s after the end of the 15th puff, and the short vibration time is 40ms, so as to effectively remind the user to master the smoking amount and prevent excessive smoking.

[0143] In some embodiments of the present application, the airflow sensor 121 can also output a low level when detecting the airflow, and output a high level when detecting no airflow. The main control module 166 can judge whether the user is smoking according to the level information with different logic levels output by the airflow sensor 121, and the specific judgment method is not limited to the above description.

[0144] In some embodiments of the present application, when the main control module 166 disconnects the power supply of the battery 127 to the heating component 146 when T2 is greater than t5, the heating component 146 stops heating. For example, when the main control module 166 disconnects the power supply of the battery 127 to the heating component 146 when T2 is greater than 5 s, the heating component 146 stops heating. This can prevent users from smoking excessively.

[0145] In some embodiments of the present application, after the cartridge 11 and the cigarette rod 12 are combined, the main control module 166 detects the data information of the authentication circuit 112 electrically connected to the cartridge pins 1623 in the PCB module 151. In some embodiments, the authentication circuit 112 includes a resistor representing the flavor information of the cartridge 11, that is, different resistance values correspond to different flavored cartridges. For example, when the resistance is 2 ohms, it represents that the cartridge 11 combined with the cigarette rod 12 is a grapefruit flavored cartridge. When the resistance is 4 ohms, it represents that the cartridge 11 combined with the cigarette rod 12 is a mint flavored cartridge. It should be noted that the specific resistance value and the corresponding flavor of the cartridge 11 are not limited to this. It can be determined according to the actual situation. When the main control module 166 detects that the resistance value of the resistor connected to the cartridge pin 1623 is 2 ohms, it indicates that the cartridge 11 is a grapefruit flavored cartridge.

[0146] In some embodiments of the present application, the authentication circuit 112 includes an encryption chip (not shown in the figure). The encryption chip stores encrypted data information of the cartridge 11, and the data information includes a unique ID number, cartridge flavor, cartridge oil volume, etc. The main control module 166 includes a decryption module corresponding to the encryption chip, and the decryption module includes a decryption chip. The decryption module is used to decrypt the encrypted information when the cartridge 11 and the cigarette rod 12 are in a combined state, and send a decryption success message after successful decryption, and send a decryption failure message after decryption failure. After receiving the decryption success message, the main control module 166 supplies power between the battery 127 and the heating circuit 111. The main control module 166 drives the indicator light 126 to flash quickly 3 times and drives the motor 122 to vibrate briefly 3 times. After successfully decrypting the encrypted data information obtained from the encryption chip, the main control module 166 turns on the Bluetooth mode and sends a broadcast signal through the antenna 170.

[0147] In some embodiments of the present application, the main control module 166 does not respond to the voltage or current change between the cartridge pins 1621 and 1622 after receiving the decryption failure message. In some embodiments of the present application, the main control module 166 responds to the voltage or current change between the cartridge pins 1621 and 1622 after receiving the decryption success message. In some embodiments of the present application, the main control module 166 does not respond to the level information output by the airflow sensor 121 after receiving the decryption failure message. In some embodiments of the present application, the main control module 166 responds to the level information output by the airflow sensor 121 after receiving the decryption success message.

[0148] In some embodiments of the present application, the main control module 166 obtains the acceleration value of the acceleration sensor 129 and determines the downward tilt angle of the cartridge 11 according to the obtained acceleration value. As Figure 18 shown, when the electronic cigarette 10 is placed horizontally, that is, the electronic cigarette 10 shown in state A, the downward tilt angle determined by the main control module 166 is 0°. At this time, the main control module 166 does not output any action instructions. When the electronic cigarette 10 is placed obliquely and the mouthpiece 141 is tilted downward, the main control module 166 determines that the downward tilt angle is not less than a preset threshold α. Wherein, α can be set to 20° and stored in the memory 124, but is not limited thereto. As Figure 18 shown in state B of the electronic cigarette 10, when the user uses the electronic cigarette 10 to suck and the mouthpiece 141 is tilted downward, it can be determined that the user is reverse sucking the electronic cigarette 10. However, since the downward tilt of the mouthpiece 141 of the electronic cigarette 10 will cause the e-liquid in the storage chamber 1434 not to penetrate into the heating assembly 146 through the heating top cover 144 and the heating silica gel body 145 due to the influence of gravity, when the user reverse sucks for too long, the e-liquid in the heating assembly 146 will be burned dry, thereby causing the heating assembly 146 to dry burn and a burnt smell to appear.

[0149] Therefore, when the electronic cigarette 10 is placed obliquely and the mouthpiece 141 is tilted downward, the main control module 166 determines that the downward tilt angle is not less than a preset threshold α, and at the same time detects that the output level of the airflow sensor 121 is high level and the suction time T2 is greater than the preset threshold t4, the main control module 166 drives the motor 122 to vibrate in the fourth driving mode. The fourth driving mode is: driving the motor 122 to vibrate 3 times, and each vibration time is 40 ms. Thus, it reminds the user to avoid the burnt smell caused by the dry burning of the heating assembly 146 due to too long reverse sucking time, and improves the user experience. In some embodiments of the present application, the tilt angle determined by the main control module 166 can be positive or negative, and positive and negative are used to represent different downward tilt directions. Wherein, a positive number represents that the mouthpiece 141 is tilted downward, which is the reverse sucking state; a negative number represents that the mouthpiece 141 is tilted upward, which is the normal use state.

[0150] In some embodiments of the present application, when the main control module 166 detects that the acceleration value of the acceleration sensor 129 is greater than the preset threshold a1, the wireless communication function is activated, that is, a broadcast signal is sent through the antenna 170. Among them, the wireless communication function can be a Bluetooth function, and the antenna 170 can be a Bluetooth antenna, but it is not limited thereto. As described above, it can be selected according to specific circumstances. At the same time, the main control module 166 drives the indicator light 126 in the third driving mode. The third driving mode is that the indicator light 126 flashes quickly 15 times to remind the user that the Bluetooth mode of the electronic cigarette 10 has been turned on. In addition, if it is detected again that the acceleration value is greater than the preset threshold within the preset time, that is, the user shakes the electronic cigarette again, the main control module 166 continues to drive the indicator light in the third driving mode. When the user knows that the Bluetooth mode of the electronic cigarette 10 is turned on, the user can perform Bluetooth pairing with the electronic cigarette through the mobile phone to obtain the user's smoking information and relevant data information of the cartridge 11 of the electronic cigarette 10.

[0152] As used herein, spatial relative terms, such as, "beneath", "below", "lower", "above", "upper", "lower", "left", "right", and the like, may be used herein for ease of description to describe the relationship of one element or feature to another element or feature as illustrated in the figures. In addition to the orientation depicted in the figures, spatial relative terms are intended to encompass different orientations of the device in use or operation. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptors used herein may be interpreted accordingly. It should be understood that when an element is referred to as being "connected to" or "coupled to" another element, it can be directly connected or coupled to the other element, or intervening elements may be present.

[0153] As used herein, the terms "approximately", "substantially", "essentially" and "about" are used to describe and account for small variations. When used in connection with an event or circumstance, the terms can refer to instances where the event or circumstance occurs precisely as well as instances where the event or circumstance occurs very nearly. As used herein with respect to a given value or range, the term "about" generally means within ±10%, ±5%, ±1% or ±0.5% of the given value or range. Ranges can be expressed herein as from one endpoint to another endpoint or between two endpoints. Unless otherwise specified, all ranges disclosed herein include the endpoints. The term "substantially coplanar" can refer to two surfaces positioned within a few micrometers (μm) of the same plane, e.g., within 10 μm, within 5 μm, within 1 μm or within 0.5 μm of the same plane. When referring to "substantially" the same numerical value or property, the term can refer to a value within ±10%, ±5%, ±1% or ±0.5% of the average of the value.

[0154] As used herein, the terms "approximately", "substantially", "essentially" and "about" are used to describe and account for small variations. When used in connection with an event or circumstance, the terms can refer to instances where the event or circumstance occurs precisely as well as instances where the event or circumstance occurs very nearly. By way of example, when used in connection with a numerical value, the term can refer to a range of variation less than or equal to ±10% of the numerical value, e.g., less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. By way of example, if the difference between two numerical values is less than or equal to ±10% (e.g., less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%) of the average of the value, then the two numerical values can be considered to be "substantially" or "about" the same. By way of example, "substantially" parallel can refer to an angular range of variation less than or equal to ±10° relative to 0°, e.g., less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1%, or less than or equal to ±0.05°. By way of example, "substantially" perpendicular can refer to an angular range of variation less than or equal to ±10° relative to 90°, e.g., less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1%, or less than or equal to ±0.05°.

[0155] As used herein, unless the context clearly dictates otherwise, the singular terms "a / an" and "the" may include plural referents. In the description of some embodiments, a component provided "on" or "above" another component may cover the case where the former component is directly on the latter component (e.g., in physical contact with the latter component), as well as the case where one or more intermediate components are located between the former component and the latter component.

[0156] Unless otherwise specified, spatial descriptions such as "above", "below", "on", "left", "right", "down", "top", "bottom", "vertical", "horizontal", "side", "higher than", "lower than", "upper", "on...", "under...", "downward", etc. are indicated relative to the orientation shown in the figures. It should be understood that the spatial descriptions used herein are for illustrative purposes only, and the actual implementation of the structures described herein may be spatially arranged in any orientation or manner, provided that the advantages of the embodiments of the present invention are not deviated by such arrangements.

[0157] Although illustrative embodiments have been shown and described, those skilled in the art should understand that the above embodiments should not be construed as limiting the present application, and changes, substitutions, and modifications can be made to the embodiments without departing from the spirit, principles, and scope of the present application.
