A cigarette cartridge (21) has a liquid-storage assembly and a vaporization assembly. The vaporization assembly is disposed in the liquid-storage assembly. The liquid-storage assembly has an upper cover (19) having a smog outlet (19-2), and a housing (18). The vaporization assembly has a heat-generating mechanism (111) a atomizing base (9), and a ventilation pipe (14). The heat-generating mechanism (111) is disposed on the atomizing base (9); the atomizing base (9) is sealingly arranged on one end of the housing (18), and the upper cover (19) is arranged on the other end of the housing (18) opposite to the atomizing base (9); the ventilation pipe (14) is in communication with the heat-generating mechanism (111) and the smog outlet (19-2). The space between the ventilation pipe (14), the housing (18), the atomizing base (9), and the upper cover (19) is a liquid-storage chamber (18-5).
