Further, fig. 10 is a schematic structural diagram of the atomizing core 30 according to the embodiment of the present invention, and in combination with fig. 10, the atomizing core 30 is provided with a pin 301. As an optional implementation manner, the atomizing core 30 is an atomizing core that can realize a heating function, such as a ceramic atomizing core, a cotton atomizing core, or a steel mesh atomizing core, and the atomizing core 30 is connected to the power supply terminal B1 of the electronic cigarette rod B through the pin 301, so that the tobacco tar can be atomized through heating. Alternatively, the leads 301 are made of copper or other material with good electrical conductivity. In one embodiment, the lead 301 includes a body portion 3011, a turn portion 3012, and a connection portion 3013. The main body 3011 passes through the through hole 101, the turning portion 3012 extends from the main body 3011 to the accommodating slot 102, and the connecting portion 3013 extends from the turning portion 3012 to the accommodating slot 102. The pin 301 is bent by the turning part 3012, so that the connecting part 3013 can be set at a suitable position according to actual needs, so that the connecting part 3013 is connected with the terminal 20, that is, the power supply terminal B1 of the e-cigarette rod B.

In the present embodiment, the connection portion 3013 passes through the card slot 203 and is fixed between the fixing portion 201 and the receiving slot 102. In one embodiment, a slot 204 penetrating the fixing portion 201 is formed at the bottom of the slot 203 in a direction away from the engaging portion 202, and the length of the slot 204 is less than or equal to the depth of the slot 203. The slits 204 allow the terminal 20 to elastically deform, and the length of the slits 204 affects the elastic deformation of the terminal 20. When the length of the gap 204 is less than or equal to the depth of the slot 203, the terminal 20 can be inserted into the receiving groove 102 and then can be tightly attached to the inner wall of the receiving groove 102, and it can be ensured that the connecting portion 3013 is compressed by the terminal 20, thereby preventing the electronic cigarette from being unusable due to the falling of the pin 301, and further, the atomizing core 30 can be stably electrically connected with the terminal 20.
