This approach can achieve aerosol dispersion, though. However, the drawback is also apparent that the aerosol inevitably collides with the heating element when it is separated to both sides of the heating element and the oil guide body with the suction airflow, and then is separated into both sides.

In the present embodiment, the shape of the heat generating portion 11 may include a mesh structure, a stripe structure, or a hollow through hole. Fig. 3 and 4 illustrate the structure of the heat generating portion and the structure of the heat generating sheet, taking the heat generating portion 11 as an example of a mesh structure. As shown in the drawing, the heat generating member 11 has a mesh structure overlapping the hollow portion 21. In this embodiment, the center of the mesh structure is further provided with a first through hole 14 larger than the through holes of the mesh structure, and the first through hole 14 is located above the hollow part 21.

In the present embodiment, the support sheet 2 is made of a dense ceramic substrate having such characteristics that the support sheet 2 is not permeable to gas or oil except for the above-described hollow portions 21. And the heating plate 1 is connected to the surface of the support plate 1 by welding, sintering or bonding. For example, the heat generating sheet 1 may be embedded or placed on the surface of an unsintered ceramic base, and then sintered to bond the two together; the heating sheet 1 may be bonded to the support sheet 2 by using an adhesive on the support sheet 2 that has been formed. Regardless of the manner of combining the heat generating sheet 1 and the support sheet 2, the positions of the hollow portion 21 and the mesh structure or the first through hole 14 need to be aligned. Generally, the hollow portion 21 is located at the center of the support sheet 2, and the first through hole 14 is located at the center of the hollow portion 21. In order to achieve the flow of aerosol with the suction air flow, the cutout 21 and the first through hole 14 are also aligned with the atomization space 31 and the central guide hole 41 of the oil guide body 4 forming the air flow channel 7.

Or the electrode is electrically connected with the fixing part of the heating sheet by welding or riveting.

In this embodiment, the hollow portion 21 of the support sheet 2 and the first through hole 14 of the heat generating sheet 1 are also part of the through air channel, and in general, when a suction action is applied to the atomizer, a suction air flow enters the mount 3 from the bottom end of the mount 3, enters the atomizing space 31 through the mount air flow channel 32, and then enters the suction air flow channel 61 of the oil storage space 6 through the atomizing space 31, the hollow portion 21, the first through hole 14, the central guide hole 41 and the air flow through hole 51 in sequence. Then, the above hollow part 21, the first through hole 14, the center guide hole 41, and the air flow through hole 51 collectively form the above air flow passage 7 (i.e., a through air passage). In the present embodiment, the atomizing space 31 is a recessed space provided at the top of the mount base 3 and recessed downward corresponding to the position of the heat generating body.
