This can not only prevent the aerosol-generating article from easily coming out, but also reduce the friction between the protrusion and the outer wall of the aerosol-generating article, making it easy to pull out the aerosol-generating article after the suction is completed.

  • the heating tube 200 is arranged in the containment chamber 107. Since the housing 100 is integrally formed, the number of parts is small, and the overall process is simple, which can control the cost at a relatively low level. In addition, the design of the integrally formed housing 100 avoids the problem of gaps between parts during the assembly of multiple parts, which is beneficial to reducing the overall size of the heating component.
  • the heating tube 200 communicates with the air inlet 109 on the housing 100 to form an air channel. There are few parts in the air flow path from air intake to air outlet, and the air channel has good sealing performance, which is beneficial to ensuring the consistency of the taste during the suction process.
