The liquid-conducting element is basically in the shape of a sheet and includes a first liquid-conducting portion 31a and a second liquid-conducting portion 32a; the liquid-conducting element is flexible and foldable, for example, in FIG. 12 , the first liquid-conducting portion 31a and the second liquid-conducting portion 32a can be folded in half around a fold line m. In addition, the first liquid-conducting portion 31a has an opening 314a for exposing the conductive track 431 of the heating element 40.

During the assembly process of the atomizing assembly 30a of this embodiment, as shown in FIG12 , the atomizing assembly 30a includes:

S1, attaching the heating element 40 to the second liquid-conducting portion 32a of the liquid-conducting element, as shown by arrow R3;

S2, fold the first liquid-conducting portion 31a around the fold line m, as shown by arrow R4; make the first liquid-conducting portion 31a and the second liquid-conducting portion 32a sandwich the heating element 40; and align the opening 314a of the first liquid-conducting portion 31a with the conductive track 431 on the first side of the heating element 40 to expose the conductive track 431. Then, along the longitudinal direction of the atomizer 100, the conductive track 431 is visible through the inhalation port 130; or, the projection of the conductive track 431 along the longitudinal direction of the atomizer 100 at least partially falls into the inhalation port 130. Or in some other variant embodiments, along the longitudinal direction of the atomizer 100, the aerosol output tube 11 and/or the inhalation port 130 are relatively staggered with the conductive track 431.

FIG. 13 shows an exploded schematic diagram of an atomizing assembly 30c of another embodiment before assembly; the atomizing assembly 30c of this embodiment includes:

a substantially planar extending heating element 40;

A first liquid-conducting element 31c which is substantially sheet-shaped and has an opening 314c; the first liquid-conducting element 31c is coupled to a first side of the heating element 40;

The second liquid-conducting element 32 c is substantially sheet-shaped and has a recess 324 c ; the second liquid-conducting element 32 c is coupled to the second side of the heating element 40 .

In the atomization assembly 30c of this embodiment, the opening 314c and the recess 324c are both opposite to the conductive track 431 of the heating element 40. The opening 314c is used to expose the conductive track 431 and release the aerosol. The depth of the recess 324c is about 0.5 to 2 mm. After assembly, the conductive track 431 forms a capillary gap between the recess 324c and the second liquid-conducting element 32c, and the liquid matrix can be adsorbed in the capillary gap to provide the conductive track 431 with heating and atomization, and the conductive track 431 and the second liquid-conducting element 32c are non-contact; this is beneficial for preventing the heat of the conductive track 431 from being transferred to the second liquid-conducting element 32c in large quantities.

After assembly, the first opening 314d is used to expose the conductive track 431 and release aerosol. The second opening 324d defines a capillary gap between the conductive track 431 and the third liquid-conducting element 33d to absorb the liquid matrix and make the conductive track 431 non-contact with the third liquid-conducting element 33d.

Or in more variant embodiments, the atomization assembly 30d may further include more layers of liquid guiding elements located on the first side and/or the second side of the heating element 40.
