In addition, the liquid guide holes 10b are symmetrically distributed on the body 11, so that the aerosol generating substrate in the liquid guide channel 10a can be uniformly guided to the liquid guide assembly 20 through the liquid guide holes 10b, and the atomization effect is further improved. Exemplarily, in an embodiment, the liquid guiding holes 10b are symmetrically distributed along the axial direction of the body 11. In other embodiments, the liquid guiding holes 10b are symmetrically distributed along the circumferential direction of the body 11.

In one embodiment, referring to FIG. 5, the inner diameter D of the body 11 is 0.3mm-3mm, that is, the diameter of the liquid guiding channel 10a is 0.3mm-3mm. If the inner diameter of the body 11 is too small, that is, the diameter of the liquid guiding channel 10a is too small, the flow of the aerosol generating substrate in the liquid guiding channel 10a will be affected, and the liquid supply capability of the heat generating component 100 will be reduced, thereby reducing the atomization efficiency of the atomizer 1000. If the inner diameter of the body 11 is too large, the volume of the heat generating component 100 is large, on one hand, the heat generating component occupies the internal space of the atomizer 1000, and on the other hand, the heat generating component 1000 also has a large volume, which is not favorable for the beauty of the product. By limiting the inner diameter of the body 11 to 0.3mm-3mm, the liquid supply capacity of the heating assembly 100 can be ensured, and the appearance of the atomizer 1000 can be improved.

Thus, if the axial length of the body 11 is too small, the liquid supply capacity and atomization efficiency of the heat generating component 100 may be reduced. If the axial length of the body 11 is too large, the volume of the heat generating component 100 is large, on one hand, the heat generating component occupies the internal space of the atomizer 1000, and on the other hand, the heat generating component 1000 also has a large volume and is not good for the beauty of the product.

If the width of the elongated hole is too large, the structural strength of the supporting member 10 is reduced, and the service life of the heat generating component 100 is further reduced, and meanwhile, if the width of the elongated hole is too large, liquid leakage may occur. By limiting the width of the elongated hole to 0.3mm-0.8mm, the service life of the heat generating component 100 can be prolonged while the atomization efficiency of the atomizer 1000 is ensured.

In one embodiment, with continued reference to FIG. 4, the length L4 of the elongated hole is 1mm to 3mm.

In one embodiment, with reference to fig. 4, the distance L5 between two adjacent rows of the elongated holes axially distributed along the body 11 is 0.6mm to 1.2mm. It should be noted that, the distance between two adjacent rows of elongated holes axially distributed along the body 11 is similar to the micro ribs between two adjacent rows of elongated holes, that is, the two adjacent rows of elongated holes are connected by the micro ribs, so as to ensure the strength of the support 10. If the distance between two adjacent rows of elongated holes is too small, the structural strength of the supporting member 10 is reduced, and the service life of the heating element 100 is further reduced. If the distance between two adjacent rows of elongated holes is too large, the liquid supply area of the supporting member 10 is reduced, and the liquid supply capacity and the atomization efficiency of the heating assembly 100 are further reduced. The distance between two adjacent rows of strip holes axially distributed along the body 11 is limited to be 0.6-1.2 mm, so that the service life of the heating component 100 can be prolonged while the liquid supply capacity and the atomization efficiency of the atomizer 1000 are guaranteed.

In one embodiment, with continued reference to fig. 4, the distance L6 between the slot closest to the end of the body 11 and the end of the body 11 is 1mm to 3mm.

If the distance between the edge hole and the end of the body 11 is too small, the structural strength of the supporting member 10 is reduced, and the service life of the heat generating component 100 is reduced. By limiting the distance between the elongated hole closest to the end of the body 11 and the end of the body 11 to 1mm to 3mm, the service life of the heat generating component 100 can be prolonged while the atomization efficiency of the atomizer 1000 is ensured.

In other embodiments, the equivalent aperture of the drainage holes 10b is 0.01mm to 3mm. The flow of the aerosol-generating substrate is prevented from being influenced by the small aperture, that is, the liquid supply capacity of the heating element 100 is reduced, and the structural strength of the support member 10 is reduced due to the large aperture, so that the service life of the heating element 100 is reduced, and meanwhile, if the aperture is too large, liquid leakage may be caused.

In one embodiment, referring to fig. 1 and 2, the length of the heat conductive layer 21 along the axial direction of the support 10 is greater than the length of the isolation layer 22 along the axial direction, so as to increase the contact area between the heat conductive layer 21 and the support 10 and the aerosol-generating substrate, i.e. further transfer more heat to the aerosol-generating substrate, so as to reduce the fluidity of the aerosol-generating substrate near the heat conductive layer 21, and further improve the liquid guiding effect and air exchange of the liquid guiding assembly 20.
