[0025] Embodiment 1

[0026] Referring to Figure 2 The embodiment provides a heating assembly 100, which comprises a heat-conducting member 110, a heat-exchanging member 120 and a heating member 130.

[0027] Referring to Figures 1-2 The heat-conducting member 110 has a plug-in cavity 111 and a mounting cavity 112, which are arranged along the axial direction of the heat-conducting member 110. The plug-in cavity 111 is used for inserting an aerosol generating substrate, and the plug-in cavity 111 comprises a first auxiliary heating cavity 1111 and a second auxiliary heating cavity 1112. The first auxiliary heating cavity 1111 is arranged close to the mounting cavity 112, and the second auxiliary heating cavity 1112 is arranged away from the mounting cavity 112. The inner diameter of the first auxiliary heating cavity 1111 is greater than that of the second auxiliary heating cavity 1112. The heat-exchanging member 120 is arranged in the mounting cavity 112, and the heat-exchanging member 120 has an airflow flow-through hole 121 penetrating through the heat-exchanging member 120 along the axial direction of the mounting cavity 112. The heating member 130 is arranged in the mounting cavity 112 and is in contact with the heat-exchanging member 120, so as to transfer heat to the heat-exchanging member 120. The heat-exchanging member 120 is used for heating air in the airflow flow-through hole 121, so that the heated air heats the aerosol generating substrate.

[0028] In the embodiment, the first auxiliary heating cavity 1111 and the second auxiliary heating cavity 1112 are arranged in the plug-in cavity 111 along the axial direction of the plug-in cavity 111.

By setting the inner diameter of the first auxiliary heating cavity 1111 to be greater than that of the second auxiliary heating cavity 1112, when the aerosol generating substrate is inserted into the plug-in cavity 111 for heating, the excessive space in the first auxiliary heating cavity 1111 helps to avoid excessively high temperature in the first auxiliary heating cavity 1111, thereby avoiding the aerosol generating substrate from being burnt.

[0029] In the embodiment, referring to Figure 3 The side wall of the portion of the plug-in cavity 111 close to the mounting cavity 112 is protruded radially away from the side of the plug-in cavity 111 inside, so as to form the first auxiliary heating cavity 1111.

[0030] More specifically, the cross section of the first auxiliary heating cavity 1111 along the axial direction of the first auxiliary heating cavity 1111 is trapezoidal. The inner diameter of the portion of the trapezoidal first auxiliary heating cavity 1111 close to the mounting cavity 112 is greater than that of the portion of the first auxiliary heating cavity 1111 away from the mounting cavity 112.

[0040] According to the distance from the mounting cavity 112, the inner diameter of the stepped structure close to the mounting cavity 112 is set to be larger than the inner diameter of the stepped structure away from the mounting cavity 112.

[0073] In the present embodiment, the inner side wall of the part of the plug-in cavity 111 close to the mounting cavity 112 is recessed in the radial direction away from the side of the plug-in cavity 111 inside, to form the first auxiliary heat cavity 1111.

[0074] More specifically, the inner side wall of the first auxiliary heat cavity 1111 is rectangular in cross-section along the axial direction of the first auxiliary heat cavity 1111, and the inner diameter of the inner side wall of the first auxiliary heat cavity 1111 is equal at different positions.

[0075] Please refer to Figures 2-3 The heating assembly 100 further includes a fixing member 140 arranged in the mounting cavity 112 and enclosing the heating member 130 and the heat-exchanging member 120 to fix the heating member 130 and the heat-exchanging member 120 in the mounting cavity 112. The fixing member 140 is made of ceramic material, which can not only be used to fix the heating member 130 and the heat-exchanging member 120, but also can be used for heat insulation.

[0076] The heat-conducting member 110 can be made of stainless steel.
