It is known that the atomizing core 42 is connected with the liquid storage cavity 11, the atomizing core 42 can heat the aerosol substrate in the liquid storage cavity 11 to atomize the aerosol into aerosol, and the aerosol enters the air duct 123, when the heated aerosol enters the air duct 123 with a lower temperature, condensate 50 is formed on the inner wall of the air duct 123, and the condensate 50 can be quickly separated from the air duct 123 by the oleophobic assembly 20. The long-term accumulation of the condensate 50 on the air passage can reduce the taste of the user, so that the condensate 50 is quickly separated from the air guide pipe 123 by arranging the oleophobic assembly 20 in the air guide pipe 123, so that the condensate 50 is reduced to stay and gather on the inner wall surface of the air guide pipe 123 for a long time, the condensate 50 is reduced to be sucked into the mouth of the user, the purpose of improving the taste of the user is further achieved, and the user experience is improved.
