     The present application relates to the field of atomization technology, and in particular to an atomizing structural member, an atomizing device and an aerosol generating device. 
     BACKGROUND TECHNOLOGY 
     Traditional electronic atomizing devices are mainly composed of an atomizer and a power supply component. The atomizer generally includes a liquid-storing chamber and an atomizing component. The liquid-storing chamber is used to store a medium that can be atomized, and the atomizing component is used to heat and atomize the medium to form an inhalable aerosol. The power supply component is used to provide power to the atomizing component.

The other embodiments are similar, and will not be repeated. The above-mentioned atomizing structural member is an ingenious design of the structure of the atomizing portion  111 . In one aspect, two atomizing faces are formed on the inner wall and the outer wall respectively. Since the two atomizing faces can undergo atomization action and generate aerosol respectively, it has the advantage of generation of a large amount of atomized aerosol; in another aspect, the atomizing portion  111  indirectly contacts the atomizing medium that has not been atomized in the liquid storing chamber through the liquid guiding portion  112 , so there is a relatively long distance from the atomizing medium in the liquid storing chamber, this can avoid deterioration of the atomizing medium in the liquid storing chamber by the high temperature. Further, in the case of avoiding the heating of the atomizing medium, it also has the following advantages: the atomizing medium is a fluid, and the fluid will change its adhesion when heated. The change of the adhesion will also affect the fluidity of the fluid, thereby affecting the efficiency of the capillary action of the liquid guiding portion  112 , and changing the liquid flowing rate, so avoiding the heating of the atomizing medium can ensure uniformity of the flowing rate of the atomizing medium to a certain extent; in a further aspect, since the liquid guiding portion  112  is used to deliver the atomizing medium to the atomizing portion  111 , it has the advantage of a stable amount of delivery, thereby ensuring the stability of atomization, with the avoidance of heating of the atomizing medium, it is beneficial to ensure the uniformity of delivery rate of the atomizing medium, thereby ensuring the consistency of the atomized aerosol. 
     In one of the embodiments, the heating element  120  may be a resistance heating element. The heating element  120  may be connected to an electrode assembly of the atomizing structural member, and when connected to a power source, it heats and atomizes the atomizing medium absorbed by the atomizing portion  111  to generate aerosol. Further, in one of the embodiments, the heating element  120  may be a resistance heating element, which may be made of a conductive material such as metal or alloy. Further, in one of the embodiments, the heating element  120  may be disposed between the inner wall  114  and the outer wall  115 , and the heating element  120  may be spaced apart from the inner wall  114  and the outer wall  115 . Further, in one of the embodiments, the heating element  120  may have a uniform shape and the heating element  120  may have the same interval with the inner wall  114  and the outer wall  115 , so that the heating element  120  can have a uniform heating effect on the first atomizing face and the second atomizing face. That is, the heating element  120  has the same first distance with respect to the inner wall  114 , the heating element  120  has the same second distance with respect to the outer wall  115 , and the first distance may be equal to the second distance. The distance from the centreline of the longitudinal cross section of the heating element  120  to the outer wall  115  is the same as that to the inner wall  114 , or the distance from an edge of the heating element  120  near the outer wall  115  to the outer wall  115  is the same as the distance from an edge of the heating element  120  near the inner wall  114  to the inner wall  114 . 
     Further, in one of the embodiments, the heating element  120  may include a filament structure, a tubular structure, a spiral structure, a mesh structure, a sheet structure and a thick film structure; it is understood that the shape of the heating element  120  is not limited to these structures, as long as it can be placed evenly in the atomizing portion  111  to achieve a stable heating effect. In one of the embodiments, as shown in  FIG.  4    and  FIG.  20   , the heating element  120  may have the shape of a spiral structure; in another embodiment, as shown in  FIG.  9   , the shape of the heating element  120  may be cylindrical or a straight strip. Further, in one of the embodiments, the heating element  120  may be embedded and disposed between the outer wall  115  and the inner wall  114  of the atomizing portion  111 , and there may be a certain distance between them, so as to avoid powdering in the region where the wall thickness may be too thin when heating at high temperature, which may affect the atomization effect and even threaten the user&#39;s health. The liquid guiding portion  112  and the atomizing portion  111  may adopt an integrated design, and the liquid guiding portion  112  first delivers the atomizing medium to the outer wall  115  through the connecting faces, and then delivers it to the entire atomizing portion  111  by capillary action of ceramic, the atomizing medium saturation at the outer wall  115  may be relatively greater than the atomizing medium saturation at the inner wall  114 , in order to have atomization at the inner wall  114  and the outer wall  115  at the same time, and maintain the consistency of the aerosol concentration, the heating element  120  may be placed in the middle of the outer wall  115  and the inner wall  114 , or may be deviated towards an upper portion of the outer wall  115 . 
     When in use, the heating element  120  may be located inside the atomizing portion  111  having a hollow porous body, and both the inner wall  114  and the outer wall  115  can form an atomizing face, and the integrated liquid guiding portion  112  can evenly transfer the atomizing medium, e.g. a type of oil or paste, into the atomizing portion  111 , the aerosol generated from the inner wall  114  may be discharged through a middle air channel, i.e., the first air channel  191 , and the aerosol generated from the outer wall  115  may be discharged through a number of peripheral channels, i.e., the second air channels  192 , located between the liquid guiding portion  112  and the outer wall  115  of the atomizing portion  111 . Since the two atomizing faces of the atomizing portion  111  have atomization action, this can effectively increase the amount of atomized aerosol and improve the user&#39;s suction experience; at the same time, there is a relatively long distance between the atomizing faces and the liquid absorbing face, this can avoid the deterioration of the atomizing medium in the liquid storing chamber caused by high temperature.
