Figure 2 It is a rear view structural schematic diagram of the heating element structure of the first embodiment of the present invention. Figure 3 It is a side view structural schematic diagram of the heating element structure of the first embodiment of the present invention.

Please refer to Figures 1 to 4 , the heating element structure includes an oil guide body 11, a first conductive layer 12, a second conductive layer 13 and a third conductive layer 14. The oil guide body 11 includes a first surface 111 and a second surface 112 arranged oppositely and at least one through hole 101 penetrating the first surface 111 and the second surface 112. The first conductive layer 12 is arranged on the first surface 111, the second conductive layer 13 is arranged on the second surface 112, and the third conductive layer 14 is arranged on the hole wall of the through hole 101. The third conductive layer 14 is electrically connected to the first conductive layer 12 and the second conductive layer 13 respectively. In this embodiment, the oil guide body 11 includes porous ceramics, porous composite fibers, but is not limited thereto.

[0033] When the first conductive layer 12, the second conductive layer 13 and the third conductive layer 14 are powered on, the first conductive layer 12, the second conductive layer 13 and the third conductive layer 14 generate heat to atomize the e-liquid. The smoke can enter the through hole 101 through the third conductive layer 14 and be discharged, and can also be discharged through the side surfaces of the first conductive layer 12, the second conductive layer 13 and the oil guide body 11.

The third conductive layer 14 extends deep into the interior of the oil guide body 11, with a large heating area, which can make the temperature of most areas of the oil guide body 11 uniform, having a good atomization effect and taste, and a long service life.

[0035] Optionally, the first conductive layer 12 and the second conductive layer 13 are in a planar shape. The first conductive layer 12 covers the first surface 111, and the second conductive layer 13 covers the second surface 112; the thickness of the first conductive layer 12 and / or the second conductive layer 13 is 50 nm to 5 μm, such as 70 nm, 100 nm, 300 nm, 500 nm, 1 μm, 2 μm, 3 μm.

[0036] Optionally, the third conductive layer 14 is tubular and is attached to the inner wall of the through hole 101; the thickness of the third conductive layer 14 is 50 nm to 5 μm, such as 70 nm, 100 nm, 300 nm, 500 nm, 1 μm, 2 μm, 3 μm.
