The power board 12 supplies power to the heating core 205 through the first conductor 7 and the second conductor 8, as well as the first power connector 4 and the second power connector 5 to make it generate heat and heat the tobacco oil in the oil storage cavity 202 to generate smoke. The groove 902 and the concave space 903 are used to collect the condensate generated by the atomizer body 14 relative to the second air guide hole 301. The first through channel 907, the second through channel 908, and the third through channel 909 are communicated with the second air guide hole 301 and are staggered to ventilate the air into the second air guide hole 301.

[0044] like Fig. 9 As shown, in a specific embodiment of the utility model, the direction of airflow during smoking is specifically described. When smoking through the mouth-suction nozzle 101, the external airflow can enter the power supply cavity 603 from the first air inlet hole 1301 and the second air inlet hole 1302, and then enter the accommodating cavity 601 through the first through channel 907 and the second through channel 908, and then enter the air groove 910 through the third through channel 909, and start the airflow switch 10 to control the heating core 205 to be energized and heated, and then heat the tobacco oil to generate smoke. The airflow in the accommodating cavity 601 simultaneously passes through the second air guide hole 301 and the first air guide hole 207 in sequence to enter the mist channel 204, and then drives the heating core 205 to heat the tobacco oil to generate smoke, and then is discharged from the mist outlet channel 201 and the smoking channel 102 for the user to inhale.

[0045] like Fig.10 As shown, in a specific embodiment of the utility model, the direction of condensate and oil leakage is specifically described. The condensate generated by the liquefaction of smoke in the mist channel 204 after smoking, and the oil droplets generated by the heating core 205 under the action of gravity can flow out of the oil storage chamber 202 through the first air guide hole 207, and then flow into the groove 902 through the second air guide hole 301 for collection. After the condensate and oil leakage in the groove 902 are collected, they can flow out of the concave space 903 for collection and isolation.
