The first lead wire is led out from the first sealing member 42, can extend to the top end of the lead wire channel 54 along the periphery or through the inside of the first sealing member 42, and then is wired through the lead wire channel 54, and finally extends and passes through the second sealing member 52.

[0039] As shown in Figure 2 and Figure 3 In order to improve the oil storage effect and strengthen the atomization effect, the first oil storage cotton 71 is arranged in the first oil storage cavity, and the second oil storage cotton 72 is arranged in the second oil storage cavity.

[0040] In order to facilitate assembly, in some embodiments, as shown inFigure 2 As shown, the housing 10 includes a housing body 11 and an upper cover 12 enclosed at the upper end of the housing body 11. The mouthpiece 20 is mounted on the upper cover 12. To facilitate installation or replacement of the mouthpiece 20 during use, the mouthpiece 20 can be detachably mounted on the upper cover 12 using a snap-fit ​​mechanism. Of course, for some disposable electronic cigarettes, the mouthpiece 20 can also be integrally injection-molded with the upper cover 12 to enhance the sealing performance of the electronic cigarette.

[0041] like Figure 2 Shown and Figure 3 As shown, the control panel 30 is a large flat panel, generally disposed on the inner side of the large surface of the housing 10; Figure 3 In the figure, the left side of the control board 30 is the shell body 11 of the outer shell 10, the upper right half is the first and second atomization chambers, and the lower right half corresponds to the battery compartment. In other words, the control board 30 extends outside the battery compartment, and the part of the control board 30 that extends outside the battery compartment is electrically connected to the first lead, the second lead, and the battery 62, thereby achieving control of all three.

[0042] In some embodiments of the present invention, the first lead and the second lead can be directly electrically connected to the control board 30, such as by being directly welded to the control board 30. In other embodiments, a microphone silicone 81 can be used as an intermediate connection carrier to provide a more stable connection and reduce the welding process, thereby avoiding the adverse effects of welding temperature on the control board 30.

[0043] like Figure 3 As shown, in one embodiment, a silicone microphone 81 is disposed on the outside of the battery compartment body 61, and the control board 30 is located on this outside position. A first silicone microphone 81 hole is provided in the silicone microphone 81, and a second silicone microphone 81 hole is provided in the silicone microphone 81. The first lead wire passes through one end of the second seal 52 and is inserted into the first silicone microphone 81 hole. The second lead wire passes through one end of the second seal 52 and is inserted into the second silicone microphone 81 hole. In this embodiment, the silicone microphone 81 hole serves as a connection between the first and second leads and the control board 30. By inserting the ends of the first and second leads into the silicone microphone 81 holes, a matching connector is provided on the control board 30 to achieve a fast and highly stable electrical connection.

[0044] like Figure 3 As shown, in one embodiment, a first terminal 31 and a second terminal are provided on the control board 30. The first terminal 31 is inserted into the hole of the first microphone silicone 81, and the end of the first terminal 31 is electrically connected to the first lead located in the hole of the first microphone silicone 81. Simultaneously, the second terminal is inserted into the hole of the second microphone silicone 81, and the end of the second terminal is electrically connected to the second lead located in the hole of the second microphone silicone 81. This achieves indirect electrical connection between the first lead, the second lead, and the control board 30.

[0045] In order to effectively control the use state, in an embodiment, the first button and the second button can be arranged on the shell 10 at the same time, the first button is used for controlling the first atomization core 43, and the second button is used for controlling the second atomization core 53; in this way, the control of the first atomization core 43 and the second atomization core 53 can be realized independently, different needs of users can be adapted, and the user experience is better.

[0046] In addition, in some embodiments, in order to ensure the cleanliness at the mouthpiece 20, a top sealing piece 91 is arranged between the first atomization chamber and the inner side of the top of the shell 10, which can effectively prevent the tobacco tar in the first atomization chamber from overflowing or volatilizing from the top, and reduce the adverse effects on the mouthpiece 20.

[0047] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
