[0044] In some embodiments, the cylinder 331 in the heating element 33 can serve as a heating body to generate heat under the action of an alternating magnetic field. At least part of the cylinder 331 can be made of a magnetic material, such as the entire cylinder 331 made of SUS430 or SPCE (deep-drawing cold-rolled carbon steel material) or other materials capable of generating heat under the action of an alternating magnetic field, so that the entire cylinder 331 can generate heat under the action of an alternating magnetic field. Alternatively, only the side wall 333 of the cylinder 331 can be made of a magnetic material, so that only the side wall 333 of the cylinder 331 can generate heat under the action of an alternating magnetic field.

[0045] In some other embodiments, the heating body in the heating element 33 can be fixed to the side wall 333 of the cylinder 331.

[0046] In the embodiments in which the cylinder 331 in the heating element 33 serves as a heating body, please refer to Figure 3 and Figure 4 The position of the coil winding 35 in the extension direction of the gas channel 311 corresponds to the position of the cylinder 331 in the extension direction of the gas channel 311, that is, the coil winding 35 is located radially outside the cylinder 331, and the coil units 36 in the coil winding 35 are uniformly distributed in the axial direction of the cylinder 331 outside the cylinder 331, so that the side wall 333 of the cylinder 331 is located at a position where the magnetic field strength of the coil winding 35 is strong, and the side wall 333 of the cylinder 331 forms a main heating part in the heating element 33, and the bottom wall 337 of the cylinder 331 forms a secondary heating part in the heating element 33. On the one hand, the side wall 333 of the cylinder 331 can reach a relatively high temperature under the action of an alternating magnetic field, and on the other hand, the side wall 333 of the cylinder 331 can heat the aerosol generating article 4 close to the aerosol outlet 112, so as to shorten the aerosol generation time and the user waiting time, thereby improving the user experience.

[0047] In an embodiment, please continue to refer to Figure 3 and Figure 4 The side wall 333 of the cylinder 331 surrounds the accommodation cavity 332 and can be arranged in the extension direction of the gas channel 311. The size of the side wall 333 of the cylinder 331 is less than or equal to the size of the coil winding 35 in the extension direction of the gas channel 311, so as to reduce the temperature difference of the side wall 333 of the cylinder 331 in the extension direction of the gas channel 311, thereby improving the temperature uniformity of the side wall 333 of the cylinder 331 and improving the heating uniformity of the aerosol generating article 4. Of course, in other embodiments, the size of the side wall 333 of the cylinder 331 in the extension direction of the gas channel 311 can be greater than the size of the coil winding 35 in the extension direction of the gas channel 311.

[0048] As the end of the coil winding 35 extending in the direction of the gas passage 311 towards the end of the aerosol outlet 112 corresponds and is flush with the open end of the cylinder body 331 towards the aerosol outlet 112, the end of the coil winding 35 extending in the direction of the gas passage 311 away from the aerosol outlet 112 is located at the closed end of the cylinder body 331 or at the side of the accommodating cavity 332 away from the open end of the cylinder body 331 away from the aerosol outlet 112, or the end of the coil winding 35 extending in the direction of the gas passage 311 away from the aerosol outlet 112 corresponds and is flush with the end of the cylinder body 331 connecting with the bottom wall 337, so that the side wall 333 of the cylinder body 331 is located at a position with a stronger magnetic field strength in the coil winding 35, and the size requirement of the cylinder body 331 and the coil winding 35 in the direction of the gas passage 311 is met. The structure of the coil winding 35 and the heating element 33 can improve the conversion efficiency of electrical energy in the coil winding 35 to heat energy in the heating element 33.

[0049] In some embodiments, the atomization assembly 3 has an air inlet passage which can be located at the side of the accommodating cavity 332 away from the gas passage 311 in the direction of the gas passage 311. The air inlet passage can be formed by the second connecting member 34. The appliance body 1 is provided with an air inlet communicating with the air inlet passage. External air enters the heat insulation cavity 322 along the air inlet passage from the air inlet. The heating element of the cylinder body 331 or the cylinder body 331 can heat the airflow in the heat insulation cavity 322 to form a hot airflow. The bottom wall 337 of the cylinder body 331 has a ventilation hole communicating the heat insulation cavity 322 with the internal space of the cylinder body 331. The hot airflow in the heat insulation cavity 322 can enter the accommodating cavity 332 in the cylinder body 331 through the ventilation hole, enter the aerosol product 4 from the bottom of the aerosol product 4, and heat the aerosol product 4.

[0050] In some embodiments, please refer to Figure 3 and Figure 4The air inlet channel in the atomization assembly 3 is in communication with the gas channel 311, and the air inlet channel is arranged in the extension direction of the gas channel 311, and is located between the heat insulation cylinder 32 and the cylinder body 331 or is arranged between the side wall 333 of the cylinder body 331 and the aerosol product 4. In addition, the atomization assembly 3 further comprises an air inlet cavity located on the side of the containing cavity 332 away from the gas channel 311 in the extension direction of the gas channel 311, and the air inlet channel can be in communication with the containing cavity 332 through the air inlet cavity. The gas flow entering the air inlet channel from the aerosol outlet 112 along the gas channel 311 can be in contact with the side wall 333 of the cylinder body 331 or the heating element on the cylinder body 331, so as to heat the gas flow in the air inlet channel through the cylinder body 331 or the heating element to form a hot gas flow. In an embodiment, since the side wall 333 of the cylinder body 331 is the main heating part, the air inlet gas flow can fully contact the main heating part in the air inlet channel, which can improve the heat transfer efficiency between the main heating part and the gas flow, reduce the heat loss of the side wall 333 of the cylinder body 331, and thus improve the heat utilization rate of the atomization assembly 3.

[0051] In an embodiment, the air inlet channel is located in the heat insulation cavity 322 and between the side wall of the heat insulation cylinder 32 and the side wall 333 of the cylinder body 331. The air inlet cavity can also be located in the heat insulation cavity 322 and between the bottom wall 337 of the cylinder body 331 and the bottom wall of the heat insulation cylinder 32 or the second connecting piece 34.
