[0002] The heating method of the aerosol generating device in the related art is mainly a resistive peripheral heating method in which a metal tube is heated by a resistive heating method such as FPC, and the heat of the heated metal tube is transferred or radiated to the aerosol generating substrate.

[0003] The energy transfer path in resistance peripheral heating is as follows: heat generation by FPC or other methods - heating of metal tube - transfer / radiation to the outer wall of the housing of the aerosol generating product - transfer to the aerosol generating substrate inside the housing, etc. Heat is lost at each stage of the transfer path, and the heat utilization rate is low when the transfer path is long.

[0004] In addition, the embedded electromagnetic heating element used in the related art mainly heats the aerosol-generating substrate located near the bottom air inlet end, so the temperature of the aerosol-generating substrate located near the ceiling air outlet end is insufficient, resulting in poor taste uniformity.

[0027] 1 to 6 show a receptor 1 according to some embodiments of the present invention. The receptor 1 is used to generate heat under the action of a changing magnetic field. As shown in FIG. 1, the receptor 1 includes a side portion 11 and a ceiling portion 12. The side portion 11 is annularly disposed on the ceiling portion 12. The ceiling portion 12 is provided with a first air hole 121. The ceiling portion 12 can be disposed so as to extend from an inner wall of the side portion 11 toward a central axis of the side portion 11.

[0028] In some embodiments, the shape of the first air hole 121 may be a circular hole. The number of the first air hole 121 may be one. The one first air hole 121 is disposed coaxially with the central axis of the side portion 11. Combined with the air flow direction shown in FIG. 10, the air flow turns downward when it encounters the ceiling portion 12, so that the heat around the aerosol-generating substrate 101 at the ceiling portion of the receptor 1 can be increased without affecting the ventilation. This shortens the pre-heating time and improves the uniformity of the taste. Combined with FIG. 11, the distance between the inner wall of the side portion 11 and the central axis of the receptor 1 can be represented as A3, and the width of the ceiling portion 12 can be represented as A4. In some embodiments, the relationship between the width A4 of the ceiling portion 12 and the distance A3 between the inner wall of the side portion 11 and the central axis of the receptor 1 can be A4≦(5×A3) / 6. 2, in some other embodiments, the number of the first air holes 121 may be two.

In some embodiments, the shape of the second air hole 131 can be a circular hole. In some embodiments, the number of the first air hole 121 can be one, and the number of the second air hole 131 can be one. The one first air hole 121 and the one second air hole 131 are disposed coaxially with the central axis of the side portion 11. In combination with the air flow direction shown in FIG. 10, the air flow rising at the intake end branches into the side and the center when it encounters the bottom portion 13, so that the heat generated inside and outside the receptor 1 can be effectively utilized. In addition, the airflow turns back downward when it encounters the ceiling 12, so that the heat around the aerosol-generating substrate 101 at the ceiling of the receptor 1 can be increased, and the pre-heating time can be shortened. Combining FIG. 11, the width of the bottom 13 can be expressed as A5. In some embodiments, the relationship between the width A5 of the bottom 13 and the distance A3 between the inner wall of the side 11 and the central axis of the receptor 1 can be A5≦(5×A3) / 6. And / or the relationship between the width A4 of the ceiling 12 and the distance A3 between the inner wall of the side 11 and the central axis of the receptor 1 can be A4≦(5×A3) / 6. As shown in FIG. 4, in some other embodiments, the number of the first air holes 121 can be two, and the number of the second air holes 131 can be two. The two second air holes 131 are arranged to face the two first air holes 121.

The bottom portion 13 is provided with a second air hole 131. The shape of the second air hole 131 may be a circular hole. The number of the second air hole 131 may be one. The single second air hole 131 is disposed coaxially with the central axis of the side portion 11. When the air flow rising at the air supply end encounters the bottom portion 13, it branches into the side and the center, so that the heat generated inside and outside the receptor 1 can be effectively utilized. Combining FIG. 11, in some embodiments, the relationship between the width A5 of the bottom portion 13 and the distance A3 between the inner wall of the side portion 11 and the central axis of the receptor 1 may be A5≦(5×A3) / 6.

[0034] In some embodiments, the side 11 includes at least one through hole penetrating from the inner wall to the outer wall, thereby increasing the energy transfer of the aerosol-generating substrate 101 inside and outside the receptor 1 to maintain a relatively balanced temperature.

[0035] 7, in some embodiments, the at least one through hole includes a slot 14a, and the length of the slot 14a extends along the circumferential direction of the side portion 11.
