[0037] The present application embodiment provides an atomization device 100, such as Figure 1 and Figure 2 As shown, the atomizer 100 includes at least two atomizer assemblies 200 stacked along the axial direction L of the atomizer 100, and a pin channel 300 is provided between two adjacent atomizer assemblies 200.

The pins of the heating element 140 extend along the radial direction R of the atomizer 100, which can avoid the atomizer assembly 200 in the axial direction L, making the layout of the pins more reasonable.

[0038] In some embodiments, the pin channel 300 is filled with a sealing material (not shown in the figure), and the pins of the heating element 140 are fixed in the sealing material; wherein the sealing material is a sealing colloid, a metal seal, a ceramic seal or a plastic seal. The provision of the sealing material can prevent air leakage from the pin channel 300 when the airflow flows between the atomizer components 200.

[0039] Specifically, the sealing material can be a hard colloid, such as silicone, or a soft glue in a partial state. Examples of glue can be Kraft glue, organic silicone, epoxy resin glue, polyurethane glue, UV glue, EVA hot melt glue, etc. This type of glue is filled into the pin channel 300 after softening, and is fixed in the pin channel 300 after curing by cooling, ultraviolet irradiation, etc.

After the second pin 240 extends from the second airway 201, it will be blocked by the first atomizer 10 in the extension direction of the second airway 201. The present application sets a first pin channel 2201 between the first atomizer 10 and the second atomizer 20, so that the second pin 240 can extend from the first pin channel 2201 to the side of the second atomizer 20 and is electrically connected to the first circuit board 70.

[0050] In some embodiments, the first pin channel 2201 is filled with a sealing material, and the sealing material is sealed and connected between the second pin 240 and the side wall of the first pin channel 2201. Specifically, when the second pin 240 is inserted into the first pin channel 2201, the first pin channel 2201 can be sealed by gluing to form a sealing material, so as to fix the second pin 240 to the first sealing member 220, and to prevent air leakage from the first pin channel 2201 when the airflow flows between the first airway 101 and the second airway 201.
