Fig. 12 to 13 show an atomizing core of the present invention, which includes a base 1 and a heat-generating body 2, wherein the base 1 can be realized by using the base 1 of any of the above embodiments, and the heat-generating body 2 is provided on an atomizing surface 12 of the base 1, and the following description will be given by taking the case where the base 1 of the above eighth embodiment is used as the atomizing core.

Fig. 12 shows an atomizing core according to a first embodiment of the present invention, as shown in fig. 12, the atomizing surface 12 of the base 1 may be located on the top surface of the base 1, and the heating element 2 is disposed on the top surface of the base 1, and it can be understood that the atomized liquid is sucked by the liquid guiding surface 11 due to the capillary force, and is moved up through the liquid guiding hole 13 and transferred to the atomizing surface 12, so that the heating element 2 heats and atomizes the atomized liquid.

Wherein, the heating element 2 is arranged on the top surface of the substrate 1, and the liquid guide holes 13 on the substrate 1 are evenly distributed around the heating element 2 at intervals. The heating element 2 can cover the opening of the liquid guide hole 13 on the atomization surface 12, so that the atomization liquid transmitted to the atomization surface 12 can be sufficiently atomized. Specifically, the former is equal to the latter, or the former is larger than the latter, as compared with the length between the liquid guide holes 13 on both ends of the atomizing surface 12 in the length direction; the heating element 2 has a width equal to or larger than the length between the liquid guide holes 13 at both ends of the atomizing surface 12 in the width direction.

In some embodiments, the heating film may be coated on the substrate 1 by a screen printing process, and it is understood that the substrate 11 is used as a substrate and the heating film is coated on the substrate 1 by a screen printing process. In some embodiments, the heat generating film may be formed on the substrate 1 by a vacuum coating process, specifically, a metal material is heated under a vacuum condition to be evaporated and condensed on the surface of the atomizing surface 12 of the substrate 1, thereby forming the heat generating film.
