A connecting wall is provided between the outer wall of the atomizing cover and the inner wall of the oil separator. The oil guiding channel passes through the outer wall of the oil separator, the connecting wall, and the outer wall of the atomizing cover to the atomizing chamber. A smoke exhaust pipe is provided on the atomizing cover. The upper end of the smoke exhaust pipe is exposed at the top of the atomizing cover, and the lower end of the smoke exhaust pipe extends into the atomizing chamber. The upper end of the atomizing core is sleeved on the lower end of the smoke exhaust pipe. A first smoke exhaust channel connected to the atomizing channel is formed inside the smoke exhaust pipe.

7. The atomizer according to claim 6, characterized in that, The bottom end of the oil separator is provided with a receiving pipe, and a receiving air passage is formed inside the receiving pipe that corresponds to and communicates with the lower end of the gap. The lower end of the atomizing core extends into the receiving air passage. A base is fitted on the receiving pipe, and the inner wall of the base and the receiving air passage enclose the ventilated liquid-separating chamber. The gap corresponds to and communicates with the ventilated liquid-separating chamber. The lower end of the atomizing core is provided with a guide port that communicates with the atomizing channel. The ventilated liquid-separating chamber communicates with the atomizing channel through the guide port.

8. The atomizer according to claim 6, characterized in that, The atomizer body also includes an oil storage tube and a sealing element. The oil separator tube is inserted into the oil storage tube, and the space between the outer wall of the oil separator tube and the inner wall of the oil storage tube serves as the oil storage chamber. The lower end of the sealing element is inserted into the top opening of the oil storage tube, and the bottom end of the oil separator tube abuts against the inner wall of the oil storage tube. The bottom end of the sealing element is provided with an outer tube and an inner tube, and the inner tube is located in the outer tube. The upper end of the oil separator tube is sleeved on the outer wall of the outer tube, and the upper end of the exhaust tube is sleeved on the outer wall of the inner tube. There is a gap between the inner wall of the outer tube and the outer wall of the inner tube that communicates with the gap. The gap and the gap constitute the air guide section. A second exhaust channel that communicates with the first exhaust channel is formed inside the inner tube.

9. The atomizer according to claim 8, characterized in that, The upper end of the seal has a transverse air intake channel communicating with the space between the gaps. The upper end of the seal is fitted with an air regulating ring, which can rotate on the upper end of the seal. The air regulating ring has an air intake hole that corresponds to and communicates with the air intake channel. The air intake hole and the air intake channel constitute the air intake part.

10. The atomizer according to claim 8, characterized in that, The atomizer body also includes a mouthpiece and a cap. The cap is located at the top of the sealing element. A third smoke exhaust channel communicating with the second smoke exhaust channel is opened on the cap. The first smoke exhaust channel, the second smoke exhaust channel, and the third smoke exhaust channel constitute the smoke exhaust part. The lower end of the mouthpiece is inserted into the third smoke exhaust channel. The mouthpiece has a smoking channel communicating with the third smoke exhaust channel.
