The extractor 10 is provided with a first magnetic member 13, the first magnetic member 13 is made of a permanent magnetic material, and the suitable permanent magnetic material may be any one of an alnico permanent magnetic alloy, an iron-chromium-cobalt permanent magnetic alloy, a permanent magnetic ferrite, a rare earth permanent magnetic material, a composite permanent magnetic material, and the like.

The main body 20 is provided with a heating element 22 and a second magnetic member 23, and the heating element 22 is at least partially located in the second receiving chamber 21 and extends along the length direction of the second receiving chamber 21. The heating element 22 is used for heating the aerosol product 200 in the first accommodating chamber 11, so that part of the active substances in the aerosol product 200 are heated and volatilized to generate aerosol, the suitable aerosol product 200 can be a cigarette, the cigarette is filled with a tobacco material which can be heated and volatilized, and a user can inhale the volatilized aerosol through the filter tip part on the cigarette.

The first magnetic member 13 and the second magnetic member 23 are both disposed away from the heating element 22, so that on the one hand, the heat of the heating element 22 can be less transferred to the first magnetic member 13 and the second magnetic member 23, so as to reduce the influence of the heat on the magnetism of the first magnetic member 13 and the second magnetic member 23; on the other hand, the magnetic members generally conduct heat relatively easily, resulting in heat loss or insufficient heating temperature, and the first magnetic member 13 and the second magnetic member 23 are disposed away from the heating element 22, so that heat loss of the heating element 22 can be reduced, and heating efficiency can be improved.

In some embodiments, the first magnetic member 13 and the second magnetic member 23 may be disposed outside the second receiving chamber 21, or the first magnetic member 13 and the second magnetic member 23 may be disposed adjacent to an open end of the second receiving chamber 21, such that the first magnetic member 13 and the second magnetic member 23 are both away from the heating element 22.

By the arrangement of the embodiment, the first magnetic member 13 can be located outside the second accommodating chamber 21 and close to the opening end of the second accommodating chamber 21.

Further, the main body 20 comprises a main body housing 27, and when the extractor 10 is housed in the main body 20, the housing 14 of the extractor 10 abuts the housing 27 of the main body 20, so that the housing 14 of the extractor 10 and the housing 27 of the main body 20 together form a housing of the aerosol-generating device 100.

It should be noted that in other embodiments, the extractor 10 may not include the housing 14, and the first magnetic element 13 may be embedded in the extension 15.

In some embodiments, as shown in fig. 5 and 3, the body 20 comprises a hollow support 28 extending longitudinally within the aerosol-generating device 100, the support 28 being for providing support to the extractor 10. The hollow area of the holder 28, i.e. the second housing chamber 21 as the main body 20, i.e. the housing 12 of the extractor 10, can be housed in the hollow area of the holder 28, it being understood that the holder 28 has an open end 281 facing the extractor 10, so that the housing 12 can be housed in the hollow area of the holder 28 through this open end.

As shown in fig. 6, the second magnetic member 23 includes a laterally extending end 231 and an extending wall 232 bent from the end 231 in a direction away from the first magnetic member 12, so as to configure the second magnetic member 23 into a cover shape. The cover is configured to be in the shape of a cover body, so that the production and assembly can be facilitated, and the second magnetic element 23 can be directly sleeved on the bracket 28 from the open end 281 of the bracket 28 during the production and assembly. It will be readily understood that a through hole 2311 is formed on the end 231, the through hole 2311 communicating with the hollow area of the bracket 28, i.e. with the second housing chamber 21, so that the housing 12 of the extractor 10 can be housed in the second housing chamber 21 through this through hole 2311. With the arrangement of the present embodiment, the second magnetic member 13 can be located outside the second accommodating chamber 21 and close to the opening end of the second accommodating chamber 12.
