[0037] According to the technical scheme, the plurality of heat-conducting isolation plates 114 are arranged in the second cavity 116, the second cavity 116 is divided into a plurality of sub-cavities 1161, when the cold air flows into each sub-cavity 1161 from the air inlet 117, on one hand, the heat generated by the heating circuit 12 is transmitted to the second heat-conducting pipe 112 and the bottom wall 113, and then transmitted to the second cavity 116 to heat the cold air flow; on the other hand, the heat generated by the heating circuit 12 is transmitted to each heat-conducting isolation plate 114, and then each heat-conducting isolation plate 114 transmits the heat to the corresponding sub-cavity 1161 to heat the cold air flow, thereby increasing the heat conduction area when the cold air flow is heated; thirdly, the second cavity 116 is divided into a plurality of sub-cavities 1161, the space of each sub-cavity 1161 is reduced, which is conducive to fully heating the cold air flow in the sub-cavity 1161. Therefore, the heating assembly 10 provided by the embodiment of the present application greatly improves the heating efficiency and heating effect of the cold air flow, and then the user experience can be improved.

[0038] In an embodiment, the heating circuit 12 is arranged on the bottom wall 113, and the air inlet 117 is arranged on the second heat-conducting pipe 112. The heating circuit 12 is arranged on the bottom wall 113, and the heat generated after the heating circuit 12 is powered on can be quickly transmitted to the second cavity 116, thereby improving the heating efficiency of the air flow. In addition, the cold air flow flows from one end of the heat-conducting member 11 provided with the first heat-conducting pipe 111 to one end of the heat-conducting member 11 provided with the bottom wall 113 before flowing to the air inlet 117, and the air inlet 117 is arranged on the second heat-conducting pipe 112, which helps to shorten the flow process of the cold air flow before flowing to the air inlet 117. Of course, in other embodiments, the heating circuit 12 can also be arranged on the first heat-conducting pipe 111, or the second heat-conducting pipe 112, or arranged on the first heat-conducting pipe 111 and the second heat-conducting pipe 112 at the same time, or arranged on the bottom wall 113 and the second heat-conducting pipe 112 at the same time; the air inlet 117 can also be arranged on the bottom wall 113, or arranged on the bottom wall 113 and the second heat-conducting pipe 112 at the same time.

[0039] In an embodiment, the air inlet 117 is arranged on one end of the second heat-conducting pipe 112 close to the bottom wall 113. In this way, when the cold air flow flows into each sub-cavity 1161, it first reaches one end of the sub-cavity 1161 close to the bottom wall 113, and the heating circuit 12 is arranged on the bottom wall 113, so that the heat generated by the heating circuit 12 can quickly and fully heat the cold air flow, thereby improving the heating efficiency of the cold air flow and avoiding the cold air flow that is not fully heated from flowing into the first cavity 115.

[0040] In an embodiment, the size of the air inlet 117 along the axial direction of the second heat-conducting tube 112 is smaller than the size of the second cavity 116 along the axial direction of the second heat-conducting tube 112. In this way, the air flow entering the sub-cavity 1161 can be prevented from flowing into the first cavity 115 before being sufficiently heated due to the air inlet 117 being too large. Of course, in specific applications, as an alternative embodiment, the size of the air inlet 117 along the axial direction of the second heat-conducting tube 112 can be equal to the size of the second cavity 116 along the axial direction of the second heat-conducting tube 112.

By providing a plurality of air inlets 117 and ensuring that each sub-cavity 1161 is in communication with at least one air inlet 117, sufficient air flow can be ensured to flow into the second cavity 116.

[0042] In an embodiment, the plurality of heat-conducting isolation plates 114 are arranged in parallel and are arranged in the second cavity 116 at equal intervals in the first direction X to divide the second cavity 116 into a plurality of sub-cavities 1161, both ends of each sub-cavity 1161 are in communication with one air inlet 117, and the first direction X is perpendicular to the axial direction of the second heat-conducting tube 112. In this way, the plurality of heat-conducting isolation plates 114 are regularly arranged in an array, and by arranging the plurality of heat-conducting isolation plates 114 at equal intervals, the size of each sub-cavity 1161 in the first direction X is the same, and the air flow in each sub-cavity 1161 is heated as uniformly as possible. It should be noted that, when the aerosol generating article 200 is inserted into the first cavity 115, the end of the aerosol generating article 200 can abut against each heat-conducting isolation plate 114, so that each heat-conducting isolation plate 114 plays a role of bearing the aerosol generating article 200.

[0043] It can be understood that, in other embodiments, the plurality of heat-conducting isolation plates 114 can also be arranged at unequal intervals in the first direction X, or when the cross section of the second heat-conducting tube 112 is circular or regular polygonal, the plurality of heat-conducting isolation plates 114 can also be arranged radially around the central axis of the second heat-conducting tube 112, or the plurality of heat-conducting isolation plates 114 can also be arranged irregularly.

The first side 1141 and the second side 1142 are connected to the inner side of the second heat-conducting pipe 112, the third side 1143 is connected to the inner side of the bottom wall 113, and the fourth side 1144 is arranged close to the first heat-conducting pipe 111. The fourth side 1144 of adjacent two heat-conducting isolation plates 114 forms an air outlet 118 communicating with the corresponding sub-cavity 1161. Hot air flow can flow into the first cavity 115 from the corresponding sub-cavity 1161 through the air outlet 118. The fourth side 1144 can be used to abut against the end of the aerosol generating article 200 located in the first cavity 115. In this way, the heat-conducting isolation plate 114 is accommodated in the second cavity 116 and divides the second cavity 116 into a plurality of sub-cavities 1161 isolated from each other. It can be understood that in other embodiments, at least one of the first side 1141 and the second side 1142 can also be arranged spaced apart from the second heat-conducting pipe 112. In this embodiment, the sub-cavities 1161 are in communication with each other.

Aluminum alloy, copper, aluminum nitride and ceramic are all high-thermal-conductivity materials. In this way, the heat-conducting member 11 and the heat-conducting isolation plates 114 have high thermal conductivity, which is beneficial to heating the air flow. The heat-conducting member 11 includes the first heat-conducting pipe 111, so the first heat-conducting pipe 111 can also be used to conduct the heat generated by the heating circuit 12. When the aerosol generating article 200 is inserted into the first cavity 115, the first heat-conducting pipe 111 is arranged around the periphery of the aerosol generating article 200. The heat generated by the heating circuit 12 is transferred to the first heat-conducting pipe 111, so that the first heat-conducting pipe 111 plays a heat preservation role on the aerosol generating article 200 to prevent the aerosol generating article 200 from rapidly supercooling during the use interval.

[0046] In an embodiment, the heat-conducting member 11 and the plurality of heat-conducting isolation plates 114 are integrally formed. In this way, the assembly is facilitated and the assembly efficiency is improved.
