Detailed Implementation Methods

[0041] This application provides an atomizing device 100, as shown in Figures 1 and 2. The atomizing device 100 includes at least two atomizing components 200 stacked along the axial direction L of the atomizing device 100, with a pin channel 300 between adjacent atomizing components 200. The atomizing device 100 also includes a first circuit board 70 whose length direction is parallel to the axial direction L of the atomizing device 100. The pins of the heating element 140 in at least one atomizing component 200 extend radially R through the pin channel 300 and are electrically connected to the first circuit board 70. The pins of the heating element 140 extending radially R of the atomizing device 100 can avoid the atomizing components 200 along the axial direction L, making the pin layout more reasonable.

[0042] In some embodiments, the pin channel 300 is filled with a sealing material (not shown), and the pins of the heating element 140 are fixed in the sealing material; wherein the sealing material is a sealing gel, a metal seal, a ceramic seal, or a plastic seal. The sealing material can prevent air leakage from the pin channel 300 when the airflow flows between the atomizing components 200.

[0043] In some embodiments, the sealing material can be a rigid colloid, such as silicone, or a partially soft adhesive. Examples of adhesives include kraft glue, silicone, epoxy resin glue, polyurethane glue, UV glue, EVA hot melt glue, etc. After softening, these adhesives are filled into the pin channel 300 and then cured by cooling, ultraviolet irradiation, etc., and then fixed in the pin channel 300.

[0044] In some embodiments, as shown in FIG6, a sealing body 400 and a plate 500 are provided between two adjacent atomizing components 200 stacked along the axial direction L of the atomizing device 100, the sealing body 400 and the plate 500 surrounding to form a pin channel 300; wherein, the sealing body 400 is provided in one of the two adjacent atomizing components 200, and the plate 500 is provided in the other of the two adjacent atomizing components 200.

[0045] In some embodiments, the atomizing assembly 200 includes a first atomizer 10 and a second atomizer 20. The first atomizer 10 has a first air passage 101, and a first pin 130 is inserted into the first air passage 101. The second atomizer 20 is disposed at one end of the first atomizer 10, and the second atomizer 20 has a second air passage 201, and a second pin 240 is inserted into the second air passage 201. The second air passage 201 and the first air passage 101 are connected and extend along the axial direction L of the atomizing device 100. A first pin channel 2201 is formed between the first atomizer 10 and the second atomizer 20. A first circuit board 70 is disposed near the side of the second atomizer 20, and the second pin 240 passes through the first pin channel 2201 and is electrically connected to the first circuit board 70.

[0046] In some other embodiments, the first pin 130 may pass through the first pin channel 2201 and be electrically connected to the first circuit board 70. That is, the first pin 130 of the first atomizer 10 may extend toward the second atomizer 20 and be bent at the connection between the first atomizer 10 and the second atomizer 20 to pass through the first pin channel 2201 and be electrically connected to the first circuit board 70.

A first pin 130 extends from the heating element 140 of the first atomizer 10, and a second pin 240 extends from the heating element 140 of the second atomizer 20. The first atomizer 10 and the second atomizer 20 are arranged side by side along the extension direction of the first air passage 101. After the second pin 240 extends from the second air passage 201, it will be blocked by the first atomizer 10 in the extension direction of the second air passage 201. This application provides 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 be electrically connected to the first circuit board 70. The pin layout is simple and reasonable, which is beneficial to improving the installation efficiency of the atomizing device 100.

[0049] In some embodiments, the first air passage 101 and the second air passage 201 extend along the length direction of the first circuit board 70, and the length direction of the first air passage 101 and the length direction of the second air passage 201 may be parallel to the length direction of the first circuit board 70.

By setting the first circuit board 70 which is electrically connected to the battery cell 80, the second pin 240 does not need to bypass the first atomizer 10 and does not need to be designed in a complicated way. It can be electrically connected to the battery cell 80 through the first circuit board 70 on the side of the second atomizer 20.

[0054] In some embodiments, the first pin channel 2201 is filled with a sealing material, which seals the connection between the second pin 240 and the sidewall of the first pin channel 2201. In some embodiments, when the second pin 240 is inserted into the first pin channel 2201, the first pin channel 2201 can be sealed by applying adhesive to form a sealing material, thereby fixing the second pin 240 to the first seal 220 and preventing air leakage from the first pin channel 2201 when airflow flows between the first air passage 101 and the second air passage 201.

[0055] In some embodiments, the first seal 220 is provided with a first rib 221 on the side facing the first plate 111. The first rib 221 is arranged around the first air guide hole 2202 and the first pin channel 2201.
