Wherein, the top plate 33 is sleeved on the torsion spring shaft 31, one of the two legs of the torsion spring 32 is pressed against the main body 10, and the other is pressed against the top plate 33; when the top plate 33 is pressed by an external force, the top plate 33 can rotate around the torsion spring shaft 31, and when the top plate 33 does not have the external force, the top plate 33 rotates around the torsion spring shaft 31 and returns, so that the aerosol-forming substrate 2 is automatically ejected out of the support portion 22.

That is, the top plate 33 always tends to be pushed upward by the urging force of the lower torsion spring 32; the bottom slot 23 of the support 22 matches the top plate 33. When the slide cover 24 advances the support 22 (the direction C in fig. 4 shows the forward direction), the top plate 33 is pressed downward, and the aerosol-forming substrate 2 is returned in the support 22 and fed into the heating chamber 11. When the slide 20 moves the support 22 back (direction B in fig. 2 shows the direction of back), the top plate 33 is free to lift upward, and the top plate 33 enters the slot 23 at the bottom of the support 22 and thus pushes against the aerosol-forming substrate 2, thereby ejecting the aerosol-forming substrate 2.

Alternatively, referring to figure 7, the top plate 33 has a ramp boss 34, the ramp boss 34 comprising a ramp surface, the ramp boss 34 projecting outwardly towards the aerosol-forming substrate 2, the ramp surface being depressible during sliding of the slider 20 between the second position and the first position.
