Extractor for an aerosol-generating device

An elongated aerosol-generating device configured to receive an aerosol-generating article, comprising:

• a heater configured to heat the aerosol-generating article, the heater extending longitudinally with respect to the elongated aerosol-generating device and being further configured to penetrate an internal portion of the aerosol-generating article;
• and
• an extractor configured to extract the aerosol-generating article received in the elongated aerosol-generating device, the extractor being movably coupled to the elongated aerosol-generating device between a first position and a second position, the first position being an operating position defined by the heater being in contact with the aerosol-generating article, and the second position being an extraction position defined by the heater being separated from aerosol-generating article,
• wherein the extractor comprises a cavity configured to receive the aerosol-generating article, a first aperture being defined through an end-wall of the cavity to allow the heater to penetrate the cavity when the extractor is moved between the second position and the first position, in which the extractor further defines an air-flow channel configured to allow air flow into the cavity, an inlet of the air-flow channel being positioned radially-outward of the first aperture, and
• wherein an outer face of the end-wall abuts a portion of the elongated aerosol-generating device when the extractor is in the first position such that debris from the aerosol-generating article cannot build up in the elongated aerosol-generating device.
