One end of the feed channel 3 comprises a feed port 31 adjacent to the reservoir and the other end comprises a discharge port 33 adjacent to the wicking element 131, and aerosol matrix enters the feed channel 3 from the feed port 33 and then exits the feed channel 3 from the discharge port 33 to reach the wicking element 131.
