Detailed ways

The embodiments of the application will be described in detail below. In the full text of the specification of this application, the same or similar components and components with the same or similar functions are denoted by similar reference numerals. The embodiments related to the drawings described herein are illustrative, diagrammatic and used to provide a basic understanding of the application. The embodiments of this application should not be construed as limitations on this application.

In some embodiments of the present application, the electronic atomizer device is also called an electronic cigarette, and the electronic atomizer device includes an electronic atomizer device body and an electronic atomizer, and the electronic atomizer device body is also called a cigarette. Rod, electronic atomizer is also called smoke bomb. In some embodiments of the present application, the cartridge and the cigarette rod are separate and separate structural parts, and the cartridge is pluggable and connected to the cigarette rod. The cartridge and the cigarette rod are combined to form an electronic cigarette. In some embodiments of the present application, the cartridge and the cigarette rod are integrally formed structural members.

Fig. 1 is a schematic block diagram of an electronic cigarette according to some embodiments of the application. The electronic cigarette 10 includes a cigarette cartridge 11 and a cigarette stick 12. The cartridge 11 includes a heating circuit 111 for heating the e-liquid or similar atomizable substance stored in the cartridge 11 to form an atomized state, so that it can be inhaled 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 is used as a power source for supplying power to the electronic cigarette 10 when the electronic cigarette 11 is working.

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 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 is connected to an external power source 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.

2A-2B are schematic diagrams of the combined state of the cartridge 11 and the cigarette rod 12 of the electronic cigarette 10 according to some embodiments of the application. As shown in FIG. 2A, the cartridge 11 and the cigarette rod 12 are in an uncombined state. As shown in Fig. 2B, the cartridge 11 and the cigarette rod 12 are in a combined state. The cartridge 11 is inserted into the cigarette rod 12 to form the combined state in FIG. 2B. Due to the resistance of the cartridge 11 itself, when the cartridge 11 is inserted into the cartridge 12 and combined with the cartridge 12, the cartridge 11 will have partial pressure. The output level of the circuit connected to the cartridge 11 is detected to determine whether the cartridge 11 and the cartridge 12 are combined. Specifically, when the main control circuit 123 detects that the output level of the connecting circuit is high, the cartridge 11 and the cigarette rod 12 are in an uncombined state. When the main control circuit 123 detects that the output level of the connecting circuit is low, the cartridge 11 and the cigarette rod 12 are in a combined state. When the main control circuit 123 detects that the cartridge 11 and the cigarette rod 12 are in a combined state, the driving indicator light 126 works in a reminder mode. The reminder mode is: the indicator light 126 turns on and then gradually goes out to inform the user that the cartridge 11 and The tobacco rod 12 has been combined and can be used normally. In some embodiments of the present application, the main control circuit 123 may also detect that the output of the connection circuit is low, confirm that the cartridge 11 and the cartridge 12 are not combined, and detect that the output of the connection circuit is high. It is usually confirmed that the cartridge 11 and the cartridge 12 have been combined.

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 V2. V4 is low level, where V1 is not less than V4. For example, 0-0.25V can be preset as low level and 3.5V-5V as high level, but it is not limited to this, and can be determined according to actual conditions.

In some embodiments of the present application, as shown in FIG. 1, 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 the reminding mode, that is, the motor 122 vibrates after the time T1. For example, the motor 122 can be controlled to vibrate once 0.5 s after the cartridge 11 and the cigarette rod 12 are in the combined state, and the vibration time is 40 ms. The time and manner of the vibration of the motor 122 are not limited to those described above, and can be selected according to actual conditions. The vibration of the motor 122 informs and reminds the user that the cartridge 11 and the cigarette stick 12 have been combined and can be used normally. Among them, it should be noted that both the motor 122 and the indicator light 126 are reminding devices, which are used to remind the user that the electronic cigarette works in different states in different modes. Among them, the reminding device may also include other reminding devices. For example, a display screen may be provided in the electronic cigarette 10 to remind the user through icons, dynamic images, or text. In some embodiments of the application, the reminding device further includes a sounder and a vibrator.

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 and the authentication circuit 112 are not electrically connected. When the cartridge 11 and the cigarette rod 12 are in a combined state, the main control circuit 123 and the authentication circuit 112 are electrically connected. The authentication circuit 112 includes a resistor that characterizes the flavor information of the cartridge 11. When the cartridge 11 and the cigarette rod 12 are in a combined state, the above-mentioned connecting pin of the main control circuit 123 forms an electrical connection loop with the resistor. According to the resistance value of the resistance in each cartridge 11, the main control circuit 123 determines the level of the resistance corresponding to the connection pin, and determines the cartridge 11 of different flavors according to the different levels. For example, when the resistance is 2 ohms, it means that the cigarette cartridge 11 with a grapefruit flavor is combined with the cigarette rod 12. When the resistance is 4 ohms, it means that the menthol-flavored cartridge 11 is combined with the cigarette rod 12. It should be noted that the specific resistance value of the resistor and the corresponding flavor of the cartridge 11 are not limited to this. It can be determined according to the actual situation.

In some embodiments of the present application, as shown in FIG. 1, 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. Wherein, activating the airflow sensor 121 may be to supply power to the airflow sensor 121. It is also possible to initialize the airflow sensor 121 to prepare the airflow sensor 121 to perform a normal detection operation.

In some embodiments of the present application, after the cartridge 11 and the cigarette rod 12 are in a combined state, the user can smoke normally. The airflow sensor 121 detects a change in airflow when the user performs a suction action. When the airflow sensor 121 detects the airflow, that is, when there is air flow or change, the airflow sensor 121 outputs a high level, which means that the user is inhaling. At this time, the main control circuit 123 controls the heating circuit 111 to heat and atomize the e-liquid . When the air flow sensor 121 does not detect air flow, that is, there is no air flow or change, the air flow sensor 121 outputs a low level, which means 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 start time t2 when the high level is generated when it detects the change from low level to high level, and records the time t2 that generated the low level when it detects the next change from high level to low level. At the starting time t3, the time for the user to take a puff T2=t3-t2, where t3 is greater than t2. The main control circuit 123 counts when T2 is greater than the preset threshold t4 and increases the count value C1, for example, it may increase by 1. Among them, t4 can be set to 1s, but it is not limited to this. When the count value C1 of the main control circuit 123 within the preset time T3 is greater than the preset threshold n, the driving motor 122 and the indicator light work in the reminding mode. The reminder mode is: the motor 122 vibrates. For example, when the count value C1 of the main control circuit 123 within 10 minutes at T3 is greater than 15, the main control circuit 123 can drive the motor 122 to vibrate once 1 second after the end of the 15th suction. The vibration time is 40ms, which can effectively remind the user to grasp the amount of smoking and prevent excessive smoking.

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

In some embodiments of the present application, when the main control circuit 123 cuts off the power supply of the battery 127 to the heating circuit 111 when T2 is greater than t5, the heating circuit 111 stops heating. For example, when the control circuit 123 cuts off the power supply of the battery 127 to the heating circuit 111 when T2 is greater than 5s, the heating circuit 111 stops heating. This can prevent users from smoking excessively.

In some embodiments of the present application, as shown in FIG. 1, 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 be read and written. The memory 124 stores smoking information. The smoking information includes the ID of the cartridge 11, the number of smoking puffs, the smoking time, and so on.

The wireless communication circuit 125 is used for wireless communication. The wireless communication can adopt one or more of the following modes: Bluetooth (Bluetooth), Wi-Fi, 3G (the 3rd Generation, third-generation mobile communication technology), 4G (the 4th Generation, third-generation mobile communication technology), 5G (the 5th Generation, third-generation mobile communication technology), near field communication, ultrasonic communication, ZigBee (Zifeng Protocol), RFID (Radio Frequency Identification, radio frequency identification), etc. The main control circuit 123 interacts with the smart terminal through the wireless communication circuit 125. Smart terminals include mobile phones, computers, smart wearable devices (for example, smart watches), and tablet computers.

In some embodiments of the present application, as shown in FIG. 3, the cigarette rod 12 further includes an acceleration sensor 129, wherein 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 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 129 is activated. Wherein, starting the acceleration sensor 129 may be to supply power to the airflow sensor 129. The acceleration sensor 129 may be initialized so that the acceleration sensor 129 prepares for a normal detection operation.

In some embodiments of the present application, the main control circuit 123 acquires the acceleration information of the acceleration sensor 129, and activates the wireless communication circuit 125 when the acceleration value contained in the acceleration information is greater than a preset threshold a1. The acceleration value includes at least one of the acceleration value in the X axis direction, the acceleration value in the Y axis direction, or the acceleration value in the Z axis direction in the coordinate system. Wherein, the acceleration sensor 129 is a G-sensor (gravity sensor), but it is not limited to this. Among them, the fact that the acceleration value is greater than the preset threshold a1 can indicate that the user is shaking 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 activates the Bluetooth module when the acquired acceleration value is greater than the preset threshold a1, and sends a broadcast signal through the Bluetooth module. In addition, the main control circuit 123 is also used to work in the fourth driving mode when the acquired acceleration value is greater than the preset threshold a1 and the count value C1 increases. The fourth driving mode is: the control indicator light 126 flashes 15 times quickly to Remind the user that the Bluetooth mode of the electronic cigarette 10 is turned on. In addition, if the user performs another shaking action, the indicator light 126 will flash again 15 times. At this time, the user can perform Bluetooth matching with the electronic cigarette 10 through the smart terminal, and perform Bluetooth communication after the matching 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 according to the received smoking information, so as to better guide users in tobacco control, smoking replacement, and smoking cessation.

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 the unique ID number, the flavor of the cartridge, the amount of oil in the cartridge, and the like. 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 used to decrypt the encrypted information when the cartridge 11 and the cartridge 12 are in a combined state, and send decryption success information after the decryption is successful, and send decryption failure information after the decryption fails. After receiving the decryption failure message, the main control circuit 123 cuts off the power between the battery 127 and the heating circuit 111. After receiving the decryption success message, the main control circuit 123 drives the indicator light 126 to flash three times and the motor 123 to short-vibrate three 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.

FIG. 4 is a schematic diagram of the interaction between the electronic cigarette 10 and the smart terminal according to some embodiments of the application. The smart terminal 201 turns on Bluetooth and matches the electronic cigarette 10, and receives the data information sent by the electronic cigarette 10 after the matching is successful. The smart terminal 201 sends the above data information to the server 202. The server 202 is used to send the analyzed and processed information about the electronic cigarette 10 to the smart terminal 201. The smart terminal 201 displays the data information of the cartridge 11 through a dedicated APP, including the cigarette Flavors, daily puffs, weekly puffs, monthly puffs, cumulative puffs, remaining e-liquid and other information are displayed as a curve chart. Wherein, the remaining amount of e-liquid can be calculated based on the cumulative number of puffs for the cartridge 11.

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

In some embodiments of the present application, the electronic cigarette 10 is also prohibited from smoking in the non-smoking area. The smart terminal 201 has a positioning function. When the user carries the smart terminal 201 and the electronic cigarette 10 into the virtual geofence 301, as shown in FIG. 5, the smart terminal 201 and the electronic cigarette 10 are in a Bluetooth connection state. The smart terminal 201 automatically receives the notification of "entering the fence". When the smart terminal 201 determines that the current location is within the geofence 301, that is, it belongs to the non-smoking area information, it sends a “no smoking” instruction to the electronic cigarette 10. The main control circuit 123 of the electronic cigarette 10 switches to the "no smoking" mode after receiving the "no smoking" command, that is, disconnects the battery 127 from the electrical connection to the heating circuit 111, the heating circuit 111 is prohibited from starting the heating function, and does not respond Level information output by the airflow sensor 121. That is, even if the airflow sensor 121 detects the airflow and outputs a high level, that is, the user draws, the heating circuit 111 is not powered, that is, the heating circuit 111 cannot heat the e-liquid. Therefore, even if the user performs a smoking action on the electronic cigarette 10 after entering the non-smoking area, the electronic cigarette 10 will not heat the e-liquid to form an atomized state, which can effectively prevent the user from smoking illegally.

Wherein, the geofence 301 may be a virtual geographic boundary defined by any geofence technology, for example, an airport, a gas station, a shopping mall, etc. In addition, if the smart terminal 201 enters the geofence 301 and the smart terminal 201 determines that the geofence 301 does not belong to a non-smoking area, it will not send a “no smoking” instruction to the electronic cigarette 10.

Specifically, as shown in FIG. 6, 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 the switch 1231 and the switch 1232 are both closed, the battery 127 normally supplies power to the heating circuit 111, so that the heating circuit 111 heats the e-liquid. When at least one of the switch 1231 and the switch 1232 is turned off, the battery 127 and the heating circuit 111 are in a disconnected state, and the heating circuit 111 will not perform heating. In some embodiments of the present application, the main control circuit 123 controls the switch 1231 to close when it does not receive the no-smoking instruction and detects that the current position does not belong to the first position information, and when the output level of the connection circuit is high The switch 1232 is controlled to be closed when the voltage level is high, and the battery 124 supplies power to the cartridge 11 when the switch 1231 and the switch 1232 are both closed. In some embodiments of the present application, the main control circuit 123 controls the switch 1231 to close when it does not receive the no-smoking instruction and detects that the current position does not belong to the first position information, and when the output level of the connection circuit is low The switch 1232 is controlled to be closed when the voltage level is high, and the battery 124 supplies power to the cartridge 11 when the switch 1231 and the switch 1232 are both closed.

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 kept closed by default. When the main control circuit 123 receives the "no smoking" instruction, the control switch 1231 is switched 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 the airflow and outputs a high level, that is, the user draws, the main control circuit 123 closes the switch 1232 according to the high level signal. The battery 127 and the heating circuit 111 are still in a disconnected state. The circuit 111 will not be heated.

When the main control circuit 123 does not receive the "No Smoking" command, the switch 1231 is in the closed state. When the airflow sensor 121 detects the airflow and outputs a high level, that is, when the user draws, the main control circuit 123 responds to the high level signal The switch 1232 is closed. At this time, because the switch 1231 and the switch 1232 are both closed, the battery 127 will normally supply power to the heating circuit 111, so that the heating circuit 111 will heat the e-liquid, and the user can smoke the electronic cigarette 10 normally.

As shown in FIG. 7, when the smart terminal 201 and the electronic cigarette 10 leave the geofence 301 belonging to the non-smoking area, the smart terminal 201 automatically receives the notification of “leave the fence” and sends the “smoking permission” instruction to the electronic cigarette 10. After the main control circuit 123 of the electronic cigarette 10 receives the "smoking allowed" instruction, it switches to the "smoking allowed" mode. That is, when the main control circuit 123 switches to the "smoking allowed" mode, the airflow sensor 121 detects the airflow and outputs a high level, which means that the user is puffing, and the main control circuit 123 controls the heating circuit 111 to heat the e-liquid to make the e-liquid mist化.

Specifically, as shown in FIG. 8, the main control circuit 123 switches the switch 1231 from the open state to the closed state after receiving the "smoking allowed" instruction, that is, the electronic cigarette 10 is switched to the "smoking allowed" mode. At this time, when the airflow sensor 121 detects the airflow and outputs a high level, it means that the user is performing a normal suction. The main control circuit 123 switches the switch 1232 to the closed state according to the high level signal, because the switch 1231 and the switch 1232 are both In the closed state, the battery 127 normally supplies power to the heating circuit, so that the heating circuit 111 heats the e-liquid to form an atomized state, and the user can smoke the electronic cigarette 10 normally.

FIG. 9 is a functional block diagram of the electronic cigarette 10 according to some embodiments of the application. The tobacco rod 12 also 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, Global Positioning System) positioning module, a Beidou positioning module, or a GLONASS (Global Navigation Satellite System, global navigation satellite system) positioning module.

In some embodiments of the present application, when the user carries the electronic cigarette 10 as shown in FIG. 9 into the geofence 301, as shown in FIG. 10A, the electronic cigarette 10 automatically receives the "enter" sent by the geofence 301 through the wireless communication circuit 125. After the notification of "fence", the main control circuit 123 determines that the current location is within the geofence 301, that is, it belongs to the non-smoking area information, and prohibits the heating circuit 111 from heating. Even if the airflow sensor 121 detects the airflow and outputs a high level, that is, the user draws, the heating circuit 111 is not powered, that is, the heating circuit 111 cannot heat the e-liquid.

Returning to Figure 6, the switch 1231 is kept closed by default. When the main control circuit 123 determines that the current position is within the geofence 301, that is, it belongs to the no-smoking area, the control switch 1231 is switched 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 the airflow and outputs a high level, that is, the user draws, the main control circuit 123 closes the switch 1232 according to the high level signal. The battery 127 and the heating circuit 111 are still in a disconnected state. The circuit 111 will not be heated.

When the main control circuit 123 determines that the current location is outside the geo-fence 301, that is, it does not belong to the no-smoking area, it keeps the switch 1231 closed. When the airflow sensor 121 detects the airflow and outputs a high level, that is, when the user draws, the main control The circuit 123 closes the switch 1232 according to the high-level signal. At this time, because the switch 1231 and the switch 1232 are both closed, the battery 127 normally supplies power to the heating circuit 111, so that the heating circuit 111 heats the cigarette oil, and the user treats the electronic cigarette 10 You can suck normally.

When the user carries the electronic cigarette 10 as shown in FIG. 9 and leaves the geo-fence 301 belonging to the non-smoking area, as shown in FIG. 10B, the electronic cigarette 10 automatically receives the notification of "leave the fence" sent by 301 through the wireless communication circuit 125, the main The control circuit 123 switches to the "smoking allowed" mode. That is, when the main control circuit 123 switches to the "smoking allowed" mode, the airflow sensor 121 detects the airflow and outputs a high level, which means that the user is puffing, and the main control circuit 123 controls the heating circuit 111 to heat the e-liquid to make the e-liquid mist化.

Returning to FIG. 8, the main control circuit 123 switches the switch 1231 from the open state to the closed state after receiving the "leave the fence" notification, that is, the electronic cigarette 10 is switched to the "smoking allowed" mode. At this time, when the airflow sensor 121 detects the airflow and outputs a high level, it means that the user is performing a normal suction. The main control circuit 123 switches the switch 1232 to the closed state according to the high level signal, because the switch 1231 and the switch 1232 are both In the closed state, the battery 127 normally supplies power to the heating circuit, so that the heating circuit 111 heats the e-liquid to form an atomized state, and the user can smoke the electronic cigarette 10 normally.

FIG. 11 is a flowchart of the operation method of some embodiments of the application. The operation method in FIG. 11 is used for the electronic cigarette 10 in one or more embodiments above.

In step 1101, the main control circuit 123 detects the output level of the connection circuit. The connecting circuit is a circuit for connecting 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 partial pressure in the connection circuit. According to the output level of the connecting circuit, it can be determined whether the cartridge 11 and the cigarette rod 12 are combined.

In step 1102, it is determined whether the output level is low level? If yes, 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 connected circuit.

In step 1103, the main control circuit 123 drives the indicator light 126 and the motor 122 to operate in the reminding mode. The reminder mode is: the indicator light 126 lights up after the cartridge 11 and the cigarette stick 12 are combined, and gradually goes out; and the cartridge 11 and the cigarette stick 12 vibrate once after 0.5 seconds, 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 stick 12 have been combined and can be used normally.

FIG. 12 is a flowchart of the operation method of some embodiments of the application. The operation method in Fig. 12 can be used for the electronic cigarette 10 in one or more of the above embodiments.

In step 1201, the main control circuit 123 detects whether the cartridge 11 and the cigarette rod 12 are combined. If yes, go to step 1202; if no, continue to check.

In step 1202, the main control circuit 123 obtains the puffing time T2 of each puff of the user. Specifically, when the airflow sensor 121 detects airflow, the airflow sensor 121 outputs a high level, which means that the user is inhaling. At this time, the main control circuit 123 controls the heating circuit 111 to heat and atomize the e-liquid; When 121 does not detect the air flow, the air flow sensor 121 outputs a low level, which means 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 start time t2 of generating the high level when it detects the change from low level to high level, and records the start of generating the low level when it detects the change from high level to low level. At time t3, the user's puffing time T2=t3-t2, where t3 is greater than t2.

In step 1203, the main control circuit 123 detects whether the user's puffing time T2 per puff is greater than a preset threshold t4. If yes, go to step 1204. If not, go to step 1205 and keep the number of suction ports C1 unchanged.

In step 1204, the number of suction ports C1 is increased by one. In step 1205, keep the number of suction ports C1 unchanged.

In step 1206, the main control circuit 123 determines whether the number of suction ports C1 in the suction time T3 is greater than a preset threshold n. If C1 is greater than n, go to step 1207; if C1 is less than n, go back to step 1202.

In step 1207, the main control circuit 123 drives the motor 122 to work in the reminder mode. The reminder mode is: the motor 122 vibrates once, and the vibration time is 40ms. Among them, the reminder mode is not limited to this. In this way, the user can remind the user to control the amount of smoking and prevent excessive smoking.

FIG. 13 is a flowchart of the operation method of some embodiments of the application. The operation method in FIG. 13 can be used for the electronic cigarette 10 in one or more of the above embodiments.

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

In step 1302, the main control circuit 123 determines whether the acquired acceleration value is greater than a preset threshold. If it is, it means that the user is shaking the cigarette rod 12, and it proceeds to step 1303; if not, it returns to step 1301.

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 the reminding mode.

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

In some embodiments, the top of the magnet 1631 and the magnet 1632 is slightly higher than the cover surface of the battery holder cover 161. The magnet 1631 and the magnet 1632 are used to magnetically hold the cartridge 11 and the cigarette rod 12 firmly when the cartridge 11 and the cigarette rod 12 are combined, so as to prevent the user from sliding the cartridge 11 or the cigarette rod 12 when the user smokes the electronic cigarette 10, which improves user experience. In addition, the through hole 1614 is used to make the air flow detection port of the air flow sensor 121 inside the cigarette rod 12 communicate with the external space.

When the battery holder cover 161 covers the upper end of the battery holder 169, the

The main control module 166, the battery 127, the charging circuit 128, the motor 122, and the airflow sensor 121 are all installed in the corresponding structure in the battery holder 169, and the battery 127, the charging circuit 128, the motor 122, and the airflow sensor 121 are all connected to the main control module 166. Electric connection.

In some embodiments of the present application, the tobacco rod 12 further includes a silicone sleeve 167. The silicone sleeve 167 is used to protect the airflow sensor 121. The cigarette rod 12 further includes a light guide column holder 165. The light guide bracket 165 is disposed on the battery bracket 169 and is located on one side of the main control module 166. 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 bracket 165. When the indicator light 124 is on, the light information can be displayed to the user through the light guide bracket 165 and the through hole in the housing 171.

In some embodiments of the present application, the battery 128 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 also includes an antenna 170 for sending and receiving wireless signals. The antenna 170 is disposed in the space between one side of the battery 127 and the housing 171, and the antenna 170 is electrically connected to the main control module 166. In some embodiments of the present application, the smoking rod 12 further includes a sponge pad 164, which is disposed in the space between the other side of the battery 127 opposite to the antenna 170 and the housing 171. Wherein, the sponge pad 164 is in contact with the battery 127 and the inner wall of the housing 171 to provide cushioning force. When the cartridge 11 and the cigarette rod 12 are combined, the accommodation space in the housing 171 accommodates the lower tube body 1432 and the bottom cover 154 of the cartridge 11.

In some embodiments of the present application, when the cartridge 11 and the cigarette rod 12 are not combined, the through hole 1614 for air circulation of the battery holder cover 161 in the cigarette rod 12 can detect the air flow between the external air and the air flow sensor 121 The through holes are connected.

FIG. 24 is a schematic diagram of the air flow channel structure of the electronic cigarette 10 according to some embodiments of the application. As shown in Figure 24, when 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 housing 171 of the cigarette rod 12, and the bottom cover of the cartridge 11 There is also a gap for air circulation between 154 and the battery holder cover 161 of the cigarette rod 12, and the airflow detection through hole of the airflow sensor 121 is entered through the through hole 1614 of the battery holder cover 161 for air circulation to form the electronic cigarette 10 The air flow channel f1 through which the external air and the electronic cigarette air flow sensor 121 pass. In this way, it is ensured that the external air of the electronic cigarette 10 can effectively enter.

When the cartridge 11 of the electronic cigarette 10 is combined with the cigarette rod 12, when the user performs a smoking action, the airflow at the airflow detection through hole of the airflow sensor 121 enters the bottom cover 154 and the battery holder through the through hole 1614 at the battery holder cover 161 The gap between the covers 161, that is, when the air flow is detected, that is, the output is high. The main control module 166 enables the battery 12 to supply power to the heating assembly 146, and the heating assembly 146 heats the e-liquid. Subsequently, air enters the space between the heating assembly 146 and the oil suction pad 419 through the air pipe 152 and the through hole 1504. At this time, part of the e-liquid is atomized by heating, and the smoke formed by the airflow atomizing the e-liquid passes through the side opening 1505 is brought into the airflow channel 1433, and enters the user's mouth through the corresponding through holes on the upper tube body 1431 and the official cap 142, thereby forming the airflow channel f2 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.

In some embodiments of the present application, returning to FIG. 2A, when the cartridge 11 is not inserted into the rod 12, there is no load between the cartridge pin 1621 and the cartridge pin 1622, and the main control module 166 detects the difference between the cartridge pin 1621 and the cartridge pin 1622. The time is high. As shown in FIG. 2B, when the cartridge 11 is inserted into the cigarette rod 12, the spring pins 1621 and 1622 are electrically connected to the contact pads of the PCB module 151, that is, the PCB module 151 acts as a load and forms between the spring pins 1621 and 1622. At this time, since the PCB module 151 can be used as a load to divide the voltage, the main control module 166 detects that the elastic needle 1621 and the elastic needle 1622 are at a low level. At this time, the main control module 166 drives the indicator light 126 and the motor 122 to Reminder mode works. The reminder mode is: the indicator light 126 lights up after the cartridge 11 and the cigarette stick 12 are combined, and gradually goes out; and the cartridge 11 and the cigarette stick 12 vibrate once after 0.5 seconds, 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 stick 12 have been combined and can be used normally. In some embodiments of the present application, the main control module 166 may also detect that the output of the connecting circuit formed by the bullet needle 1621 and the bullet needle 1622 of the cigarette stick 12 is low, and confirm that the cigarette cartridge 11 and the cartridge 12 It is not combined, and it is confirmed that the cartridge 11 and the cartridge 12 are combined when it is detected that the output of the connection circuit is high.

After the user confirms that the electronic cigarette 11 is combined according to the indicator light 126 and the motor 122 prompts, the user starts to perform a normal smoking action.

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 airflow, the output level of the airflow sensor 121 changes from low to high, and the main control module 166 receives that the airflow sensor 121 changes from low to high When the signal, the output voltage is output through the elastic pin 1621 and the elastic pin 1622, and the output voltage is provided to the heating assembly 146 through the contact pad of the PCB module 151, the elastic piece 1481 and the elastic piece 1482, the thimble 1471 and the thimble 1472, so that the heating assembly 146 Heating and atomizing the e-liquid in contact with the heating assembly 146. At the same time, when the user inhales, the air enters the cartridge 11 through the air pipe 152 and the atomized smoke is delivered into the user’s mouth through the airflow channel, thus completing one time Smoking action. When the smoking action is stopped, the change of the airflow 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, the main control module 166 After acquiring the output level from high level to low level, the output voltage between the elastic needle 1621 and the elastic needle 1622 is controlled to disconnect, that is, the heating of the heating component 146 is stopped. When the main control module 166 detects that the output level of the airflow sensor 121 changes from low to high, it records the initial time t2 when the high level is generated, and the next time the output level of the airflow sensor 121 changes from high to high. When the level changes to a low level, the starting time t3 of the low level is recorded, where the time for the user to take a puff T2=t3-t2, where t3 is greater than t2. The main control module 166 counts when T2 is greater than the preset threshold t4 and increases the count value C1, for example, it can be increased by 1. Where t4 can be set to 1s, but it is not limited to this. If the user has been performing a suction action, and the count value C1 of the main control module 166 within the time T3 is greater than the preset threshold n, the driving motor 122 operates in the reminding mode. The reminder mode is: the motor 122 vibrates. For example, when the count value C1 of the main control module 166 within 10 minutes at T3 is greater than 15, the main control module 166 can drive the motor 122 to vibrate 1 second after the end of the 15th suction. Second, the short shock time is 40ms, which can effectively remind users to master the amount of smoking and prevent excessive smoking.

In some embodiments of the present application, the airflow sensor 121 may also output a low level when it detects airflow, and output a high level when it detects no airflow. The main control module 166 can determine whether the user is smoking according to the level information with different logic levels output by the airflow sensor 121, and the specific determination method is not limited to the above.

In some embodiments of the present application, when the main control module 166 turns off the battery 127 to supply power to the heating assembly 146 when T2 is greater than t5, the heating assembly 146 stops heating. For example, when T2 is greater than 5s, the main control module 166 cuts off the power supply of the battery 127 to the heating assembly 146, so that the heating assembly 146 stops heating. This can prevent users from smoking excessively.

In some embodiments of the present application, after the cartridge 11 and the cartridge 12 are combined, the main control module 166 detects data information of the authentication circuit 112 in the PCB module 151 that is electrically connected to the cartridge pin 1623. In some embodiments, the authentication circuit 112 includes a resistor that characterizes the flavor information of the cartridge 11, that is, cartridges with different flavors correspond to different resistance values. For example, when the resistance is 2 ohms, it means that the cigarette cartridge 11 with a grapefruit flavor is combined with the cigarette rod 12. When the resistance is 4 ohms, it means that the menthol-flavored cartridge 11 is combined with the cigarette rod 12. It should be noted that the specific resistance value of the resistor 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 bullet needle 1623 is 2 ohms, it indicates that the cigarette cartridge 11 is a grapefruit-flavored cartridge.

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 the unique ID number, the flavor of the cartridge, the amount of oil in the cartridge, and the like. 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 cartridge 12 are in a combined state, and send decryption success information after the decryption is successful, and send decryption failure information after the decryption fails. After receiving the successful decryption message, the main control module 166 performs power supply between the battery 127 and the heating circuit 111, and the main control module 166 drives the indicator light 126 to flash 3 times, and drives the motor 123 to vibrate 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.

In some embodiments of the present application, the main control module 166 does not respond to changes in voltage or current between the elastic needle 1621 and the elastic needle 1622 after receiving the decryption failure information. In some embodiments of the present application, the main control module 166 responds to the voltage or current change between the elastic needle 1621 and the elastic needle 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 information. 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 information.

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 shown in FIG. 18, 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 will not output any actions. instruction. When the electronic cigarette 10 is tilted and the mouthpiece 141 is tilted downward, the main control module 166 determines that the tilt angle is not less than a preset threshold α. Among them, α can be set to 20° and stored in the memory 124, but it is not limited thereto. As the electronic cigarette 10 shown in state B in FIG. 18, when the user uses the electronic cigarette 10 to smoke and tilts the cigarette holder 141 downward, it can be determined that the user is puffing the electronic cigarette 10 backwards. However, because the cigarette holder 141 of the electronic cigarette 10 is tilted downward, the e-liquid in the storage compartment 1434 will not penetrate into the heating assembly 146 through the heating top cover 144 and the heating silicone body 145 due to the influence of gravity. Therefore, when the user takes time If it is too long, the e-liquid in the heating assembly 146 will be dried, so that the heating assembly 146 will burn dry and a burnt smell will appear.

Therefore, when the electronic cigarette 10 is placed obliquely and the cigarette holder 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 and the puffing time When 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: the driving motor 122 vibrates 3 times, and each vibration time is 40 ms. Therefore, the user is reminded to avoid the burnt smell caused by the dry burning of the heating element 146 caused by the long pumping time, which improves the user experience. In some embodiments of the present application, the tilt angle determined by the main control module 166 may be a positive number or a negative number, and positive and negative are used to indicate different downward tilt directions. Among them, a positive number indicates that the cigarette holder 141 is tilted downward, which is in a backward smoking state; a negative number indicates that the cigarette holder 141 is tilted upward and is in a normal use state.

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 may be a Bluetooth function, and the antenna 170 may be a Bluetooth antenna, but is not limited to this. As mentioned above, it can be selected according to specific conditions. At the same time, the main control module 166 drives the indicator light 126 in the third drive mode, and the third drive mode is that the indicator light 126 flashes 15 times quickly 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 performs a shaking action again, the main control module 166 continues to drive the indicator light in the third driving mode. After the user knows that the Bluetooth mode of the electronic cigarette 10 is turned on, the user can perform Bluetooth matching with the electronic cigarette through the mobile phone to obtain the user's smoking information and related data information of the cartridge 11 of the electronic cigarette 10.
