When the first casing 131 is set as a magnetically conductive casing, the first casing 131 generates heat as a heat source and does not directly contact the object 20 to be heated, so that the first casing 131 is not easy to remain dirt and easy to clean. Moreover, when the first casing 131 is a magnetically conductive casing, the heating assembly 130 heats the air around the object to be heated 20 through the first casing 131, thereby heating the object to be heated 20 (that is, air heating), and the heat The conduction efficiency of air is lower than that of metal pipes, so the surface of the object 20 to be heated will not be heated too quickly during the heating process, which can make the object 20 to be heated more uniformly.

So that the volume of the heating chamber 131a will not be too large. It can be understood that, in other embodiments, the installation position can also be located on the insertion end. In other embodiments, the first shell 131 is a non-magnetic shell. At this time, the heating assembly 130 also includes a magnetically conductive insert, which is fixed on the bottom wall of the heating chamber 131a. When in use, the object to be heated 20 is placed in the heating cavity 131a and inserted on the magnetically conductive insert, the conductive coil 133 is energized, and the magnetically conductive insert generates heat due to electromagnetic induction, thereby heating the object to be heated 20 from the center of the object to be heated 20 Simultaneously, the heat-generating magnetically conductive insert also heats the conductive coil 133 sleeved on the first housing 131, and then the air flowing in the conductive coil 133 is also heated, and the heated air flows into the heating chamber 131a to further heat the object to be heated 20. That is to say, the object 20 to be heated in the heating chamber 131a is heated from the hot air and the magnetically conductive insert. Optionally, the material of the non-magnetic shell is non-metallic material or metal non-magnetic material. It can be understood that, in some embodiments, the first casing 131 is a magnetically conductive casing, and the heating assembly 130 also includes a magnetically conductive insert. In this case, both the first casing 131 and the magnetically conductive insert can serve as a heating element.

Of course, when the first casing 131 is a magnetically conductive casing, the material of the first casing 131 is not limited to iron, iron alloy or 316 stainless steel, and can also be other magnetically conductive materials that can generate heat through electromagnetic interaction with the conductive coil 133; The material of the magnetic plug-in is not limited to iron, iron alloy or 316 stainless steel, and can also be other magnetically conductive materials that can generate heat through electromagnetic interaction with the conductive coil 133 .

When the above-mentioned heating assembly 130 is in use, outside air enters the fluid channel from the air inlet 135 of the fluid channel of the conductive coil 133, and flows out through the air outlet 136 to enter the heating chamber 131a. After electrification, the battery generates heat due to induction, and then directly and/or indirectly heats the object 20 to be heated. The air further heats the object 20 to be heated after entering the heating chamber 131a. The above-mentioned heating assembly 130 has at least the following advantages:

(1) The setting of the hollow conductive coil 133 makes the conductive coil 133 not only serve as the conductive coil 133 in the electromagnetic induction heating, but also serves as a fluid channel for the outside air to enter the first housing 131, so that the electromagnetic induction produces a part of the heat that is originally lost While being able to be used again, it also acts as a heat sink for the conductive coil 133 itself, which can improve the heat utilization rate, reduce the heat transfer from the coil to the second housing 132, reduce the temperature of the surface of the electronic atomizer 10, and have a heat insulation effect .

(2) The hollow conductive coil 133 is superimposed with the functions of conduction and air circulation, which can realize air heating. Compared with the traditional air heating with a separate air cavity, it can save more space and make the size of the electronic atomizer 10 smaller .

(3) Setting the first housing 131 as a magnetically conductive housing can make the first housing 131 a heating component in electromagnetic induction heating, and at the same time, the size of the first housing 131 is set so that the object to be heated 20 is placed in it There are intervals from time to time to realize the air heating of the object to be heated 20, which makes the heated temperature of the object to be heated 20 more uniform. For example, when the object to be heated 20 is an atomized medium carrier, the mouthfeel has an obvious relationship with the heating time. Compared with the direct contact conduction heating method, air heating is non-contact heating. After the suction requirement is met, the heating time The change will not cause a large change in the taste, making the taste more stable. In addition, the size of the first housing 131 is set so that there is a gap when the atomized medium carrier is placed therein, which can also prevent the atomized medium carrier from directly contacting the heat source, reduce the formation and residue of dirt, and basically do not need to be cleaned.
