[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Pod-based e-cigarettes typically consist of a device and multiple replaceable cartridges. These cartridges contain e-liquids with different compositions and varying melting points. Therefore, during atomization, the device needs to output different power levels to match the atomization temperature required by each cartridge. To achieve this, the device must accurately identify the type of cartridge loaded and adjust the output power accordingly.

[0047] However, the existing methods for identifying cartridges using e-cigarette devices have certain limitations.

[0048] For example, one method of identifying cartridges based on the heating wire resistance determines the cartridge type by analyzing the resistance of the heating wire. The resistance of the heating wire is typically between 0.4Ω and 1Ω, allowing for differentiation between different cartridge types. However, in actual production, there is a certain margin of error in the heating wire resistance. For instance, at 0.4Ω, the error range is ±0.06Ω, meaning the difference between the upper limit of 0.4Ω and the lower limit of 0.6Ω is only 0.08Ω. This narrow error range may cause the e-cigarette to fail to accurately identify the cartridge type in certain situations, resulting in poor atomization. Another method, based on the heating wire inductance, identifies the cartridge type by detecting the inductance of the heating wire. The inductance of the heating wire is approximately 50nH. By comparing the detected inductance, the type of cartridge can be determined. However, in design... When the circuit detects inductance, a corresponding inductance detection circuit needs to be added, which will increase manufacturing costs. Furthermore, the accuracy of the heating wire inductance is greatly affected by the manufacturing process and is difficult to control strictly, which may cause the e-cigarette device to fail to accurately identify the cartridge type. In addition, the management of the inductance value curve becomes more complicated during assembly and production, further increasing manufacturing costs. The e-cigarette device identifying cartridges based on adding a storage chip inside the cartridge involves installing a storage chip inside the cartridge and communicating with the e-cigarette device through an additional pin, so that the e-cigarette device can read the identification information in the storage chip to identify different cartridge types. However, additional hardware (i.e., storage chip and corresponding circuit) must be added for each cartridge, which accounts for too high a cost. Moreover, since the number of cartridges is often much larger than the number of e-cigarette devices, this high cost will significantly increase the total cost in mass production and use.

[0049] In summary, the existing methods for identifying cartridges in e-cigarette devices have certain limitations. They are expensive to manufacture and have low accuracy, which can lead to poor atomization due to misidentification of cartridge type.

[0050] To address the aforementioned issues, this application proposes a pod-based electronic cigarette, which provides a new, low-cost, and highly accurate method for identifying pods within the cigarette holder. This overcomes the limitations of existing methods and avoids poor atomization due to misidentification of pod type. The specific implementation principle will be explained in detail in the following embodiments.

[0051] Please see Figure 1 This is a schematic diagram of a refillable electronic cigarette according to an embodiment of this application. Figure 1 The pod-based electronic cigarette includes a cigarette holder 110 and a test cartridge 120. The cigarette holder 110 includes a main control board circuit 111, and the test cartridge 120 includes a cartridge board circuit 121.

[0052] In one feasible implementation, when the test cartridge 120 is first inserted into the cigarette device 110, the main control board circuit 111 is connected to the insertion terminal of the cartridge board circuit 121, and the insertion terminal of the cartridge board circuit 121 outputs a first insertion voltage to the main control board circuit 111; after the test cartridge 120 is first inserted into the cigarette device 110, when the test cartridge 120 is pulled out and then inserted into the cigarette device 110 in the reverse direction, the main control board circuit 111 is connected to the insertion terminal of the cartridge board circuit 121, and the insertion terminal of the cartridge board circuit 121 outputs a second insertion voltage to the main control board circuit 111; the main control board circuit 111 is used to receive the first insertion voltage and / or the second insertion voltage, and output the type of the test cartridge 120.

[0053] Among them, cartridge 120 to be tested refers to cartridges that need to be tested for cartridge type.

[0054] It should be noted that the first and second insertions of the test cartridge 120 into the cigarette holder 110 must be in opposite directions. That is, if the test cartridge 120 is inserted into the cigarette holder 110 in the forward direction the first time, then the test cartridge must be inserted into the cigarette holder 110 in the reverse direction the second time.

[0055] Understandably, inserting the cartridge twice in opposite directions can improve the accuracy of cartridge type identification, thus avoiding poor atomization due to misjudging the cartridge type.

[0056] In some embodiments, after receiving the first insertion voltage and / or the second insertion voltage, the main control board circuit 111 can perform voltage value matching in a preset cartridge type identification table according to the voltage value of the first insertion voltage and / or the voltage value of the second insertion voltage, and take the cartridge type corresponding to the matched voltage value as the type of the output cartridge 120 to be tested; wherein, the preset cartridge type identification table can be preset by the operator according to the actual situation, and the type of the output cartridge 120 to be tested can be in the form of an electrical signal.

[0057] In this application embodiment, a new method for identifying cartridges in a cigarette holder 110 is proposed, which is low-cost and highly accurate, thereby solving the limitations of existing methods for identifying cartridges in a cigarette holder 110 and avoiding the problem of poor atomization effect due to misjudging the type of cartridge.

[0058] It should be noted that this application previously studied a single-voltage e-cigarette device 110 for identifying the cartridge. However, since voltage can fluctuate under certain conditions, there is a problem of poor atomization due to misjudging the cartridge type. This application uses two different voltage e-cigarette devices 110 for identifying the cartridge. By using two different voltages as a reference, the problem of poor atomization due to misjudging the cartridge type under certain conditions caused by voltage fluctuations can be avoided.

[0059] based on Figure 1 Please see Figure 2 This is a schematic diagram of a refillable electronic cigarette according to an embodiment of this application. Figure 2 .

[0060] In one feasible implementation, when the insertion end of the cartridge circuit 121 is the positive insertion end, the first end of the main control board circuit 111 is connected to the first end of the cartridge circuit 121, the second end of the main control board circuit 111 is connected to the second end of the cartridge circuit 121, and the third end of the main control board circuit 111 is connected to the third end of the cartridge circuit 121; when the insertion end of the cartridge circuit 121 is the reverse insertion end, the first end of the main control board circuit 111 is connected to the third end of the cartridge circuit 121, the second end of the main control board circuit 111 is connected to the second end of the cartridge circuit 121, and the third end of the main control board circuit 111 is connected to the first end of the cartridge circuit 121.

[0061] In this embodiment, the output voltage can be changed simply by changing the connection between the first and third terminals of the cartridge board circuit 121 of the cartridge 120 under test and the main control board circuit 111 of the cigarette rod 110, thereby realizing the differentiation of cartridge types, reducing hardware manufacturing costs, and improving the accuracy of cartridge type identification.

[0062] based on Figure 2 Please see Figure 3 This is a schematic diagram of a refillable electronic cigarette according to an embodiment of this application. Figure 3 The cigarette cartridge circuit 121 in the above embodiment includes a first resistor R1 and a second resistor R2.

[0063] In one feasible implementation, one end of the first resistor R1 is the first end of the cartridge circuit 121, the other end of the first resistor R1 is connected to one end of the second resistor R2 and is the second end of the cartridge circuit 121, and the other end of the second resistor R2 is the third end of the cartridge circuit 121.

[0064] It should be noted that the first insertion voltage and / or the second insertion voltage output from the insertion terminal of the cartridge board circuit 121 of the cartridge 120 to the main control board circuit 111 are the voltage division of the first resistor R1 and / or the voltage division of the second resistor R2. That is, if the first insertion voltage is the voltage division of the first resistor R1, then the second insertion voltage is the voltage division of the second resistor R2; if the second insertion voltage is the voltage division of the second resistor R2, then the second insertion voltage is the voltage division of the first resistor R1.

[0065] In this embodiment, the voltage divider effect of the two resistors in the cartridge board circuit 121 can provide two different insertion voltages (i.e., the first insertion voltage and the second insertion voltage) to transmit information about the cartridge type. This allows the main control board circuit 111 to more accurately identify the type of inserted cartridge based on the received first insertion voltage and / or second insertion voltage values, thereby adjusting the output power to ensure the best atomization effect.

[0066] Furthermore, compared to adding extra hardware (such as memory chips), this method, which uses only resistors for voltage division to achieve cartridge recognition, is more economical and efficient. Simplifying the hardware structure can reduce production costs, making it suitable for large-scale production applications, and it also helps to reduce the overall size of replaceable e-cigarettes.

[0067] Please continue reading. Figure 3 The cigarette cartridge circuit 121 in the above embodiment also includes a heating wire TE1.

[0068] In one feasible implementation, one end of the heating wire TE1 is connected to one end of the first resistor R1, and the other end of the heating wire TE1 is connected to the other end of the second resistor R2.

[0069] In this embodiment, by connecting the heating wire TE1 with the first resistor R1 and the second resistor R2 in a specific way, the test cartridge 120 can be connected to the circuit and enter the working state smoothly regardless of whether it is inserted in the forward or reverse direction. This significantly enhances the flexibility and compatibility of the cartridge insertion method and can effectively improve the user experience.

[0070] Furthermore, this connection design reduces the occurrence of one-way configurations that fail to connect, reduces design complexity, lowers manufacturing costs, and improves production stability and efficiency.

[0071] based on Figure 1 Please see Figure 4 This is a schematic diagram of a refillable electronic cigarette according to an embodiment of this application. Figure 4 The main control board circuit 111 in the above embodiment includes a control module 410.

[0072] In one feasible implementation, the first terminal of the control module 410 is the first terminal of the main control board circuit 111, the second terminal of the control module 410 is the second terminal of the main control board circuit 111, and the third terminal of the control module 410 is the third terminal of the main control board circuit 111. When the test cartridge 120 is inserted into the cigarette rod 110 for the first time, the first terminal of the control module 410 outputs a charging supply voltage to the insertion terminal of the cartridge board circuit 121, and the insertion terminal of the cartridge board circuit 121 outputs a first insertion voltage to the second terminal of the control module 410. After the test cartridge 120 is inserted into the cigarette rod 110 for the first time, when the test cartridge 120 is pulled out and inserted into the cigarette rod 110 for the second time in the reverse direction, the first terminal of the control module 410 outputs a charging supply voltage to the insertion terminal of the cartridge board circuit 121, and the insertion terminal of the cartridge board circuit 121 outputs a second insertion voltage to the second terminal of the control module 410. The third terminal of the control module 410 is grounded.

[0073] In this embodiment, by introducing a control module 410, when the test cartridge 120 is inserted into the e-cigarette rod 110 in opposite directions twice, the control module 410 outputs the same charging voltage from the first end and receives two different voltages from the second end. That is, by controlling the quantitative amount, the cartridge type can be identified according to the variable, which can further improve the identification accuracy of the cartridge type and thus optimize the atomization effect.

[0074] based on Figure 4 Please see Figure 5 This is a schematic diagram of a refillable electronic cigarette according to an embodiment of this application. Figure 5 The main control board circuit 111 in the above embodiment also includes a power supply output module 510.

[0075] In one feasible implementation, the power supply output module 510 is connected to the first end of the control module 410, and the output end of the power supply output module 510 is the first end of the main control board circuit 111. When the test cartridge 120 is inserted into the cigarette rod 110 for the first time, the first end of the control module 410 outputs a charging voltage to the power supply output module 510, and the output end of the power supply output module 510 outputs a power supply voltage to the insertion end of the cartridge board circuit 121. The insertion end of the cartridge board circuit 121 outputs a first insertion voltage to the second end of the control module 410. After the test cartridge 120 is inserted into the cigarette rod 110 for the first time, when the test cartridge 120 is pulled out and inserted into the cigarette rod 110 for the second time in the opposite direction, the first end of the control module 410 outputs a charging voltage to the power supply output module 510, and the output end of the power supply output module 510 outputs a power supply voltage to the insertion end of the cartridge board circuit 121. The insertion end of the cartridge board circuit 121 outputs a second insertion voltage to the second end of the control module 410.

[0076] In this embodiment, by introducing a power output module 510, the connection between the control module 410 and the cartridge board circuit 121 is indirectly made through the power output module 510. This avoids electrical interference or poor contact problems that may be introduced by direct connection, and improves reliability and the accuracy of the cigarette rod 110 in recognizing the cartridge.

[0077] based on Figure 5 Please see Figure 6 The above is a schematic diagram of the power supply output module in an embodiment of this application. The power supply output module 510 in the above embodiment includes a third resistor R43, an NMOS transistor Q6, a fourth resistor R41, a fifth resistor R36, a sixth resistor R30, and a P-channel field-effect transistor chip Q4.

[0078] In one feasible implementation, one end of the third resistor R43 is connected to the gate of the NMOS transistor Q6, the drain of the NMOS transistor Q6 is connected to one end of the fourth resistor R41 and one end of the fifth resistor R36, the other end of the fourth resistor R41 is connected to the third pin of the P-channel MOSFET chip Q4, the other end of the fifth resistor R36 is connected to the fourth and fifth pins of the P-channel MOSFET chip Q4, the fourth and fifth pins of the P-channel MOSFET chip Q4 are both connected to one end of the sixth resistor R30, the other end of the sixth resistor R30 is connected to the first, second, sixth, seventh, and eighth pins of the P-channel MOSFET chip Q4, the other end of the third resistor R43 and the source of the NMOS transistor Q6 are both grounded; one end of the third resistor R43 is connected to the first end of the control module 410, and the other end of the sixth resistor R30 is the output end of the power supply output module 510.

[0079] In some embodiments, when the charging and supply voltage output by the MCU chip is transmitted to one end of the third resistor, the NMOS transistor Q6 is turned on and the P-channel MOSFET Q4 is also turned on, so that the other end of the sixth resistor R30 outputs the supply voltage.

[0080] In this embodiment, the power supply output module 510, which includes a third resistor R43, an NMOS transistor Q6, a fourth resistor R41, a fifth resistor R36, a sixth resistor R30, and a P-channel MOSFET chip Q4, can achieve precise voltage control and transmission, helping to improve the accuracy of identifying the type of e-cigarette cartridge.

[0081] Understandably, through this reasonable circuit design, the voltage output by the power supply output module 510 can be precisely controlled, ensuring high precision and stability in the interaction with the cartridge board circuit 121, thereby more accurately identifying the type of cartridge.

[0082] Please continue reading. Figure 5The control module 410 in the above embodiment includes a single-chip microcomputer (MCU).

[0083] In one feasible implementation, the first pin of the microcontroller chip MCU is the first terminal of the control module 410, the second pin of the microcontroller chip MCU is the second terminal of the control module 410, and the third pin of the microcontroller chip MCU is the third terminal of the control module 410.

[0084] In this embodiment of the application, by introducing a single-chip microcontroller (MCU) as the control module 410, the design of the control module 410 can be greatly simplified, the number of components can be reduced, and the manufacturing cost can be lowered.

[0085] In addition, the microcontroller chip (MCU) has high stability and reliability, can work for a long time, and can ensure stable performance to achieve precise control, which is especially important in adjusting the atomization power.
