[0026] like Figure 1-6 As shown, a dual-cartridge electronic cigarette that is easy to assemble and fill with oil includes a shell 1, in which an upper cartridge 2 and a lower cartridge 3 are fixedly installed. The upper cartridge 2 and the lower cartridge 3 are stacked in the shell 1, and the lower end of the upper cartridge 2 is connected to the upper end of the lower cartridge 3. An upper heating core 21 is provided in the upper cartridge 2, and the upper heating core 21 is used to generate heat and atomize the oil in the upper cartridge 2 into an aerosol. A wire tube 31 is provided in the lower cartridge 3 for the wires of the upper heating core 21 to pass through, and the wire tube 31 passes through the upper and lower end surfaces of the lower cartridge 3. In the process of assembling the electronic cigarette, the wires of the upper heating core 21 of the upper cartridge 2 can be passed through the wire tube 31 and then welded to the control board 6 below, which is convenient for straightening the wires of the heating core and facilitating assembly, thereby reducing the difficulty of assembly.

[0027] An oil filling hole 32 is provided at the end of the lower cigarette cartridge 3 away from the upper cigarette cartridge 2. A mounting bracket 4 is fixedly installed in the housing 1. The end of the lower cigarette cartridge 3 away from the upper cigarette cartridge 2 is fixedly connected to the mounting bracket 4. A lower sealing member 5 is provided on the mounting bracket 4. A blocking cap 51 is provided on the lower sealing member 5. The blocking cap 51 is detachably connected to the oil filling hole 32. By providing the oil filling hole 32 on the lower cigarette cartridge 3, the upper cigarette cartridge 2 and the lower cigarette cartridge 3 can be assembled separately before oil filling during assembly, and the order of oil filling is not restricted. Either the upper cigarette cartridge 2 or the lower cigarette cartridge 3 can be oiled first, thereby simplifying the assembly process, reducing the risk of oil leakage, and improving assembly efficiency.

[0028] During the specific assembly, the wires on the upper heating core 21 can be passed through the wire tube 31, and then the upper cigarette cartridge 2 and the lower cigarette cartridge 3 can be limited and fixed; then oil is added, and after the lower cigarette cartridge 3 is filled with oil, the sealing cap 51 is used to seal the oil filling hole 32, and then the lower cigarette cartridge 3 is installed on the mounting bracket 4, so that the upper cigarette cartridge 2, the lower cigarette cartridge 3 and the mounting bracket 4 become a whole, and then the whole is installed in the shell 1 to complete the assembly.

[0029] In this embodiment, there are two oil filling holes 32 and two sealing caps 51 , and the two are arranged in a one-to-one correspondence; in other embodiments, the number of oil filling holes 32 can also be any other number.

[0030] To improve the stability of the structure, a wire hole 52 is provided on the lower seal 5 at a position corresponding to the wire tube 31. After the wire tube 31 is installed in the lower cigarette cartridge 3, the end of the wire tube 31 away from the upper cigarette cartridge 2 is inserted into the wire hole 52, thereby securing the wire tube 31 to the lower seal 5. During assembly, the wires of the upper heating core 21 pass through the wire tube 31 and then through the wire hole 52, allowing them to pass through the lower seal 5 for easy welding to the control board 6 below.

[0031] A control board 6 and a battery 7 are mounted on the mounting bracket 4. The battery 7 and the lower cigarette cartridge 3 are electrically connected to the control board 6, respectively. The wires of the upper heating core 21 pass through the wire tube 31 and the wire hole 52 and are then welded to the control board 6. An air inlet 11 is provided at one end of the housing 1, and a mouthpiece 12 is provided at the other end. The upper cigarette cartridge 2 and the lower cigarette cartridge 3 are respectively connected to the air inlet 11, and the upper cigarette cartridge 2 and the lower cigarette cartridge 3 are respectively connected to the mouthpiece 12. During the inhalation process of the electronic cigarette, the user inhales through the mouthpiece 12, thereby triggering a start signal. The control board 6 controls the battery 7 to supply power to the upper cigarette cartridge 2 and the lower cigarette cartridge 3, respectively, so that the upper cigarette cartridge 2 and the lower cigarette cartridge 3 work simultaneously, heating the tobacco oil and atomizing it. The atomized aerosol will flow to the mouthpiece 12 respectively and eventually be inhaled by the user.

[0032] During the assembly process, different flavors of e-liquid can be injected into the upper and lower cartridges 2 and 3, so that the electronic cigarette can inhale different flavors to meet the needs of different users and enhance the user experience.

[0033] In this embodiment, a dust cap 8 is provided on the mouthpiece 12, and the dust cap 8 is detachably connected to the mouthpiece 12. When the electronic cigarette is not in use, the dust cap 8 can be plugged into the mouthpiece 12 to reduce the entry of foreign matter such as dust and water vapor into the electronic cigarette through the mouthpiece 12, thereby ensuring a good smoking experience. When it is necessary to inhale, the dust cap can be removed from the mouthpiece 12 to inhale through the mouthpiece 12.

[0034] The upper cartridge 2 includes an upper oil cup 22 for holding the e-liquid. The lower end of the upper oil cup 22 is connected to the lower cartridge 3. An upper oil storage cotton 23 is placed inside the upper oil cup 22, and the upper heating core 21 is disposed within the upper oil storage cotton 23. The upper end of the upper oil cup 22 is an open structure, and an upper seal 24 is provided on the upper end of the upper oil cup 22. The upper seal 24 is sealed and connected to the upper end of the upper oil cup 22. During assembly, after the upper oil cup 22 is filled with oil, the upper seal 24 is placed on the upper end of the upper oil cup 22, sealingly connecting it to the upper oil cup 22 and fixing it. This creates a closed cavity within the upper oil cup 22, reducing the possibility of e-liquid leakage. During the inhalation process, the e-liquid flows from the upper oil storage cotton 23 into the upper heating core 21, and the battery 7 supplies power to the upper heating core 21, so that the upper heating core 21 heats the e-liquid and atomizes it into aerosol. After atomization, the aerosol flows into the nozzle 12 through the upper heating core 21 and is finally inhaled by the user.

[0035] The lower cartridge 3 includes a lower oil cup 33 for holding the oil. The lower oil cup 33 is connected to the mounting bracket 4. A lower oil reservoir 34 is located inside the lower oil cup 33. A wire tube 31 passes through the lower oil cup 33 and the lower oil reservoir 34 and is sealed to the lower oil cup 33. A lower heating core 35 is located inside the lower oil reservoir 34 and is electrically connected to the control board 6. During the inhalation process, the oil flows from the lower oil reservoir 34 into the lower heating core 35. The battery 7 supplies power to the lower heating core 35, causing the lower heating core 35 to heat the oil and atomize it into an aerosol. After atomization, the aerosol flows through the lower heating core 35 into the mouthpiece 12 and is ultimately inhaled by the user.
