It is to be understood that FIG. 1 is only an example of a structure and is not intended to be limiting. The aerosol-generating device 100 comprises a filter 10 and a host 20. The host 20 is used to generate aerosol. The filter tip 10 stores a conditioning fluid. The heat generated by the host 20 during aerosol generation can atomize the conditioning fluid in the filter tip 10 to generate a mixed aerosol containing the atomized conditioning fluid.

The method comprises the following specific steps:

the filter 10 includes:

the filter tip body 11 is provided with a liquid storage cavity 111;

the atomizing core 12, a first cavity 121 is formed in the atomizing core 12, and a first porous structure is arranged on the cavity wall of the atomizing core 12;

a sleeve 13, wherein the sleeve 13 is sleeved on the atomizing core 12, a second cavity 131 is formed between the inner wall of the sleeve 13 and the outer wall of the atomizing core 12, and the second cavity 131 is communicated with the first cavity 121 through the first porous structure; wherein, one of the first cavity 121 and the second cavity 131 is a liquid guiding groove, and the other is an atomizing cavity; the liquid guide groove is used for guiding the regulating liquid in the liquid storage cavity 111 into the groove, and the regulating liquid in the liquid guide groove is used for permeating into the atomization cavity through the first porous structure;

The heating body 4 is used for heating the cigarette 3 contained in the smoke tube 2 to generate mixed aerosol, and the mixed aerosol sequentially passes through the atomizing cavity and the suction port 14.

In this application, the distance between the distal end of inserting cut-off position 21 and atomizing core 12 of cigarette 3 is restricted at-1 mm ~ 1mm, when cigarette 3 inserts in tobacco pipe 2, the near-end of cigarette 3 can only stretch into near the insert cut-off position 21 of tobacco pipe 2, can't continue to stretch into to the near-end of tobacco pipe 2 again, because the distance between the near-end of cigarette 3 and the distal end of atomizing core 12 is restricted at-1 mm ~ 1mm, therefore, heating member 4 heats the heat of the cigarette aerosol that the in-process of cigarette 3 in the tobacco pipe 2 produced can atomize the regulation liquid in the atomizing chamber and form the atomizing regulation liquid to form the mixed aerosol that includes cigarette aerosol and atomizing regulation liquid, and, because the distance between the near-end of cigarette 3 and the distal end of atomizing core 12 is very close, therefore, heating member 4 heats cigarette 3 in-process in the tobacco pipe 2 can also be close to the regulation liquid heating of cigarette 2 forms the mixed aerosol that has mixed aerosol to atomize and atomizing regulation liquid, and can further improve the atomizing regulation liquid in the atomizing chamber and further atomizing regulation efficiency.

In this embodiment, the insertion cut-off 21, i.e., the distance between the end surface of the distal end of the sleeve 13 and the end surface of the distal end of the atomizing core 12, is preferably 0.5mm. It is to be understood that this distance is illustrative only and not limiting. At this moment, cigarette 3 quilt the produced smog aerosol's of heating body 4 heating heat passes through air transfer extremely second cavity 131 (promptly, the atomizing chamber) under the sufficient condition of temperature of second cavity 131, the regulating fluid is in follow in first chamber 121 the first porous structure of atomizing core 12 oozes extremely the second cavity 131 and atomize in the second cavity 131, however, because the heat capacity of air is great, the produced smog aerosol of cigarette 3 transfer extremely the in-process of second cavity 131, the temperature of the produced smog aerosol of cigarette 3 descends gradually, leads to the produced smog aerosol of cigarette 3 is right second cavity 131 and atomizing core 12's heating is less, leads to the mobility of the regulating fluid in the first chamber 121 (promptly, the guiding gutter) of atomizing core 12 is less relatively, by first chamber 121 oozes extremely the seepage speed of second cavity 131 is less relatively, therefore, the atomizing efficiency that the regulating fluid is atomized is relatively lower.
