the first and second magnetic members 30, 40 are configured to stably hold the aerosol-generating device 200 in a charging position in which the aerosol-generating device is placed in the receiving chamber 20 for charging or in an extraction position in which the device is removed from the receiving chamber 20. In particular, in an alternative implementation, the first magnetic member 30 and the second magnetic member 40 are magnets, and hold the aerosol-generating device 200 in different positions by magnetic attraction.

Further figures 4 and 5 show schematic views of the aerosol-generating device 200 in different positions, respectively; in particular, the method comprises the steps of,

Of course, at least a portion of the aerosol-generating device 200 adjacent the upper end 110 when received in the receiving cavity 20 abuts the extractor 10 and can be pushed at least partially out of the receiving cavity 20 as the extractor 10 slides, thereby forming an extraction position as shown in fig. 5 for easy extraction.

In a more specific implementation, the structures and the matching manners of the charging device 100 and the aerosol-generating device 200 are shown in fig. 6 to 9; wherein,

the charging device 100 includes:
