The cartridge module 100 includes an oil cup 101, a wick 102, a first seal 103, and a second seal 104. The oil cup 101 has a receiving cavity. The wick 102 is disposed in the receiving cavity. The upper end of the oil cup 101 in the first direction is provided with a first opening 1011, and the lower end of the oil cup 101 in the first direction is provided with a second opening 1012. The opening area of the first opening 1011 is larger than the opening area of the second opening 1012. The outer wall surface of the first seal 103 is in interference connection with the inner wall surface of the first opening 1011, and the outer wall surface of the second seal 104 is in interference connection with the inner wall surface of the second opening 1012.
[0034] In short, the oil cup 101 of the electronic cigarette provided by the present utility model has a receiving cavity. Since the opening area of the first opening 1011 is larger than that of the second opening 1012, it is convenient to put the oil storage cotton 102 into the receiving cavity from top to bottom through the first opening 1011. The outer wall surface of the first seal 103 is in interference connection with the inner wall surface of the first opening 1011, and the outer wall surface of the second seal 104 is in interference connection with the inner wall surface of the second opening 1012. The openings of the oil cup 101 are sealed by an interference fit assembly method, ensuring the sealing performance of the oil cup 101 and preventing the e-liquid in the oil storage cotton 102 from leaking outside the oil cup 101.
[0035] Further, a plurality of first annular protrusion parts 1031 are convexly provided on the outer wall surface of the first seal 103, and the first annular protrusion parts 1031 are in contact with the inner wall surface of the first opening 1011. By adding a plurality of first annular protrusion parts 1031, the size of the outer contour of the lower section of the first seal 103 can be further increased, thereby ensuring the tight fit between the first seal 103 and the first opening 1011 of the oil cup 101 and improving the sealing performance of the upper end of the oil cup 101.
[0036] Furthermore, a plurality of second annular protrusion parts 1041 are convexly provided on the outer wall surface of the second seal 104, and the second annular protrusion parts 1041 are in contact with the inner wall surface of the second opening 1012. By adding a plurality of second annular protrusion parts 1041, the size of the outer contour of the second seal 104 can be further increased, thereby ensuring the tight fit between the second seal 104 and the second opening 1012 of the oil cup 101 and improving the sealing performance of the lower end of the oil cup 101. Exemplarily, the materials of the first seal 103 and the second seal 104 can be silicone or rubber materials.
[0037] Further, the cartridge module 100 further includes a cartridge housing 105 with a mouthpiece 1051. The oil cup 101 is located inside the cartridge housing 105 to prevent the oil cup 101 from being damaged by collision with external objects. The mouthpiece 1051 is located at the upper end of the cartridge housing 105, and an anti-slip structure is provided on the outer surface of the cartridge housing 105 to increase the contact friction between the hand and the cartridge housing 105.
[0038] Optionally, a sealing ring 106 is sleeved on the outer wall surface below the oil cup 101, and the sealing ring 106 is clamped between the oil cup 101 and the inner wall surface of the cartridge housing 105. By adding the sealing ring 106, the assembly stability between the lower part of the oil cup 101 and the inner wall surface of the cartridge housing 105 can be ensured.

[0041] Exemplarily, the heating unit 107 includes a first pipe section 1071 and a second pipe section 1072 that are connected and communicate with each other. A heating core 1073 is provided on the second pipe section 1072. One end of the first pipe section 1071 away from the second pipe section 1072 passes through the first seal 103 and communicates with the mouthpiece 1051 of the cartridge housing 105. One end of the second pipe section 1072 away from the first pipe section 1071 passes through the second seal 104 and communicates with the bottom of the cartridge housing 105. A through hole 10721 is provided on the second pipe section 1072 to facilitate the e-liquid in the oil storage cotton 102 to flow into the second pipe section 1072 and be heated by the heating core 1073, and the generated aerosol is discharged from above the first pipe section 1071.
[0042] Further, the electronic cigarette further includes a rod module 200. The rod module 200 includes a rod housing 201. The rod housing 201 is provided with a first magnetic attraction member 202, and the cartridge housing 105 is correspondingly provided with a second magnetic attraction member 1052. The first magnetic attraction member 202 can be attracted to the second magnetic attraction member 1052. By using the method of mutual attraction between the first magnetic attraction member 202 and the second magnetic attraction member 1052, the assembly of the rod module 200 and the cartridge module 100 is realized. The magnetic attraction force between the first magnetic attraction member 202 and the second magnetic attraction member 1052 is less than the pulling force of the user, which is convenient for the user to disassemble the rod module 200 and the cartridge module 100. Exemplarily, the first magnetic attraction member 202 is an iron sheet, and the second magnetic attraction member 1052 is a magnet.
