The first condensate baffle 100 may be made of materials such as high density polyethylene or oil-absorbing cotton.

When the e-liquid in the oil tank 10 leaks, it may flow into the smoking port 21 from the gap between the oil tank 10 and the inside of the cigarette holder 20. Therefore, in this embodiment, the first condensate baffle 100 further includes a baffle for absorbing the flow direction The adsorption layer of the e-liquid in the smoking port 21 of the cigarette holder 20 . Since the first condensate baffle 100 is located between the opening of the oil tank 10 and the smoking port 21 , an adsorption layer is provided on the first condensate baffle 100 to absorb the e-liquid before it flows into the smoking port 21 . The adsorption layer can be composited on the first condensate baffle 100 by using composite materials.

Due to the separation function of the first condensate baffle 100 , the condensate is blocked outside the space communicated with the smoking port 21 of the cigarette holder 20 and cannot enter the smoking port 21 . Therefore, when the condensate in the cartridge 1 flows to the end face of the oil tank 10 facing the cigarette holder 20, the first condensate baffle 100 can block the condensate and prevent the condensate from continuing to flow in the direction of the smoking port 21 of the cigarette holder 20. , to prevent the condensate in the cartridge 1 from flowing into the user's mouth.

As shown in FIG. 2 , due to the blocking effect of the first condensate baffle 100 , the condensate cannot flow out from the smoking port 21 , so the condensate in the cartridge 1 can easily flow back to the circuit board of the electronic cigarette from the position of the atomizing end cap 50 , causing damage to the circuit board. For this reason, in this embodiment, a second condensate baffle 110 is provided on the inner wall of the atomizing end cover 50 on the side close to the electrode to isolate the area where condensate is generated in the cartridge 1 from the circuit board in the electronic cigarette, so as to prevent the condensate from condensing. The area where the condensate is generated from the cartridge 1 flows into the circuit board of the electronic cigarette, so that the service life of the electronic cigarette is significantly prolonged. In addition, in this embodiment, the inner wall of the atomizing end cover 50 close to the electrode side and the end face of the oil tank 10 facing the atomizing device 30 are separated by a preset distance.

The electrodes are used to electrically connect the power supply and the atomizing device 30 . A heating element is arranged in the atomizing core 31, and the heating element generates heat for atomizing the e-liquid after the atomizing core 31 is powered on.

The e-liquid stored in the accommodating chamber of the oil tank 10 enters into the atomizing core 31, and the heating element in the atomizing core 31 heats the e-liquid so that it is atomized and then enters the first flue 53, and is followed by the first flue 53. The airflow in the first flue 53 flows through the second flue 60 together and then flows out from the smoking port 21 of the cigarette holder 20 . The coating layer 32 coated on the outer wall of the atomizing core 31 separates the accommodating chamber of the fuel tank 10 from the first flue 53, so that the airflow channel between the first flue 53 and the smoking port 21 forms a closed airflow. In this way, the user can generate negative pressure in the first flue 53 when inhaling through the smoking port 21, so that the airflow mixed with the atomized e-liquid will flow from the first smoke under the atomizing device 30 under the action of negative pressure. The position of the channel 53 continuously flows to the smoking port 21 . During assembly, when the mounting seat 51 passes through the first through hole formed on the second condensate baffle 110, the inner wall of the first through hole is closely attached to the outer wall of the mounting seat 51, connecting the hollow part of the mounting seat 51 with the smoke.
