[0044] The electronic cigarette as described above has the following working process:

[0045] 1. A user selects a first flavor, inserts the cartridge 1 into the smoking set 2 in a first state, and the pin electrode F 21 is in top contact with the connecting electrode F 11 , the pin electrode F 22 is in top contact with the connecting electrode F 12 , the pin electrode F 23 is in top contact with the connecting electrode F 13 , the pin electrode F 24 is in top contact with the connecting electrode F 14 .

[0046] 1-1. Initially, the single / dual firing switch 22 is in the off position, and the MCU control chip controls the first MOSFET Q1, the second MOSFET Q2 and the third MOSFET Q3 to be turned off, so there is no voltage output from the power supply circuit.

[0047] 1-2. When the single / dual firing switch 22 is set to position 1, the MCU control chip controls the first MOSFET Q1 to conduct, while the second MOSFET Q2 and the third MOSFET Q3 remain off. The battery voltage flows from pad P. 20 The output passes sequentially through the spring electrode F 21 Connecting electrode F 11 and pad P 10 Connect to pad P respectively 14 and pad P 17 The corresponding energy is transmitted to the first positive electrode in the first dual-heating component 15 and the third positive electrode in the second dual-heating component 16. At this time, the first common negative electrode in the first dual-heating component 15 is connected to the solder pad P. 16 solder pad P 12 Connecting electrode F 13 , spring electrode F 23 and pad P 22 Connected to the ground terminal; the second common negative electrode in the second dual-heat-generating component 16 is connected to pad P. 19 solder pad P 13 Connecting electrode F 14 , spring electrode F 24 Connect to pad P 23 The circuit remains open. Therefore, only one heating wire (the heating wire between the first positive electrode and the first common negative electrode) in the first dual-heating assembly 15 corresponding to the left oil storage tank 13 is conductive and generates heat.

[0048] 1-3. When the single / dual firing switch 22 is set to position 2, the MCU control chip controls the first MOSFET Q1 and the second MOSFET Q2 to conduct, while the third MOSFET Q3 remains off. The battery voltage flows from pad P. 20 and pad P 21 Output. From pad P 20 The output voltage passes sequentially through the spring electrode F 21 Connecting electrode F 11 and pad P 10 Connect to pad P respectively 14 and pad P 17 The corresponding data is transmitted to the first positive electrode in the first dual-heating component 15 and the third positive electrode in the second dual-heating component 16; from pad P 21 The output voltage passes sequentially through the spring electrode F 22 Connecting electrode F 12 and pad P11 Connect to pad P respectively 15 and pad P 18 The heat is then transmitted to the second positive terminal in the first dual-heating assembly 15 and the fourth positive terminal in the second dual-heating assembly 16. At this time, as described in steps 1-2 above, the first common negative terminal in the first dual-heating assembly 15 is connected to the ground terminal, while the second common negative terminal in the second dual-heating assembly 16 remains open-circuited. Therefore, both heating wires in the first dual-heating assembly 15 corresponding to the left oil storage tank 13 (the heating wire between the first positive terminal and the first common negative terminal, and the heating wire between the second positive terminal and the first common negative terminal) are conductive and heating, achieving single / dual-heating switching in the first flavor.

[0049] 2. After steps 1-3 above, the user switches to the second flavor, rotates the tobacco cartridge 1 180° and inserts it into the smoking device 2 in the second position, and the electrode F... 21 With connection electrode F 12 Top contact connection, spring electrode F 22 With connection electrode F 11 Top contact connection, spring electrode F 23 With connection electrode F 14 Top contact connection, spring electrode F 24 With connection electrode F 13 Top-contact connection.

[0050] 2-1. Based on steps 1-3 above, the single / dual generator switch 22 is in position 2, the first MOSFET Q1 and the second MOSFET Q2 are turned on, and the third MOSFET Q3 remains off. The battery voltage flows from pad P. 20 and pad P 21 Output. From pad P 20 The output voltage passes sequentially through the spring electrode F 21 Connecting electrode F 12 and pad P 11 Connect to pad P respectively 15 and pad P 18 The corresponding data is transmitted to the second positive electrode in the first dual-heating component 15 and the fourth positive electrode in the second dual-heating component 16; from pad P 21 The output voltage passes sequentially through the spring electrode F 22 Connecting electrode F 11 and pad P 10 Connect to pad P respectively 14 and pad P 17 The corresponding energy is transmitted to the first positive electrode in the first dual-heating component 15 and the third positive electrode in the second dual-heating component 16. At this time, the first common negative electrode in the first dual-heating component 15 is connected to the solder pad P. 16 solder pad P 12 Connecting electrode F 13, spring electrode F 24 Connect to pad P 23 The circuit remains open; the second common negative electrode in the second dual-heat-generating component 16 is connected to pad P. 19 solder pad P 13 Connecting electrode F 14 , spring electrode F 23 and pad P 22 It is connected to the grounding terminal. Therefore, both heating wires in the second dual-heating assembly 16 corresponding to the right oil storage tank 14 (the heating wire between the third positive electrode and the second common negative electrode and the heating wire between the fourth positive electrode and the second common negative electrode) are conducting and generating heat.

[0051] 2-2. When the single / dual generator switch 22 is set to position 1, the first MOSFET Q1 is turned on, while the second MOSFET Q2 and the third MOSFET Q3 remain off. The battery voltage flows from pad P. 20 Output, via spring electrode F 21 Connecting electrode F 12 and pad P 11 Connect to pad P respectively 15 and pad P 18 The heat is then transmitted to the second positive terminal in the first dual-heating assembly 15 and the fourth positive terminal in the second dual-heating assembly 16. At this time, as described in step 2-1 above, the first common negative terminal in the first dual-heating assembly 15 remains open, and the second common negative terminal in the second dual-heating assembly 16 is connected to the ground terminal. Therefore, only one heating wire (the heating wire between the fourth positive terminal and the second common negative terminal) in the second dual-heating assembly 16 corresponding to the right oil reservoir 14 conducts heat, achieving single / dual-heating switching in the second flavor.

[0052] 2-3. When the single / dual generator switch 22 is turned to the off position, the first MOSFET Q1, the second MOSFET Q2 and the third MOSFET Q3 are all turned off, and there is no voltage output from the power supply circuit.

[0053] In summary, the dual-flavor electronic cigarette with single / dual-coil switching provided by this utility model embodiment has several advantages. First, by configuring the single / dual-coil switching heating element in the dual-flavor switching electronic cigarette, each flavor can be switched between single and dual-coil modes. Users can experience two different flavors and the power and taste of both single and dual-coil modes using a single cartridge, enhancing the user's sensory experience. Second, the two sets of single / dual-coil switching heating elements only require four connecting electrodes for power supply, reducing the number of connecting electrodes and facilitating the miniaturization of electronic cigarettes.

[0054] The above description is only a specific implementation of the present application. It should be pointed out that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered as the protection scope of the present application.
