A cartridge comprises an outer sleeve tube, an air passage tube located in the outer sleeve tube, and an atomization device. An annular space between the outer sleeve tube and the air passage tube forms a liquid storage chamber configured for storing tobacco liquid. The liquid storage chamber has an annular opening, which is blocked with a porous liquid conducting body. The porous liquid conducting body has a first surface and an opposite second surface, and is configured for conveying the tobacco liquid from the first surface to the second surface and supplying the tobacco liquid to the atomization device, the first surface being in contact with the tobacco liquid in the liquid storage chamber and the second surface being in contact with the atomization device. The atomization device is configured for aerosolizing the tobacco liquid to generate an aerosol to be expelled into the air passage tube.
