The atomizing base 11 may include a base body 111 having a ring shape and a cylindrical body 112 integrally combined above the base body 111 along a longitudinal direction in some embodiments. The base 111 may be provided with an electrode post 113 along a longitudinal direction, and the electrode post 113 is used for electrically connecting with the heat generating member 15. Generally, an insulating sleeve 114 is further disposed between the outer ring of the electrode column 113 and the inner ring of the holder body 111 to insulate and hermetically connect the electrode column 113 and the holder body 111.

Specifically, fin structure 160 may include a plurality of transverse first fins 161 and/or a plurality of longitudinal second fins 162. The plurality of first fins 161 may be arranged in parallel and at intervals along the axial direction of the leakage block 16, and a first reservoir 1610 penetrating the outer circumferential surface of the leakage block 16 is formed between every two adjacent first fins 161. The plurality of second fins 162 may be spaced along the top periphery of the leakage barrier 16, and a second reservoir 1620 penetrating the outer ring of the top surface of the leakage barrier 16 is formed between every two adjacent second fins 162. The widths of the first reservoir 1610 and the second reservoir 1620 are small enough to generate a capillary force on the leakage liquid, so that when the leakage liquid flows into the first reservoir 1610 and the second reservoir 1620, a liquid film is formed in the first reservoir 1610 and the second reservoir 1620, and the leakage liquid can be stored in the first reservoir 1610 and the second reservoir 1620. In the embodiment, the fin structure 160 includes a plurality of first fins 161 located at the lower portion and a plurality of second fins 162 located at the upper portion, so that the leakage liquid is stored in the second fins 162 located at the upper portion, and when the second fins 162 store more leakage liquid, the leakage liquid slowly permeates into the first fins 161 located at the lower portion, so that the leakage liquid preventing effect is better.

In some embodiments, the widths of the first reservoir 1610 and the second reservoir 1620 (i.e., the pitches of the first fins 161 and the second fins 162) are 0.1mm to 0.5mm, preferably 0.2mm to 0.4mm, respectively, and the thicknesses of the first fins 161 and the second fins 162 are 0.2mm to 0.8mm, preferably 0.3mm to 0.6mm, respectively.

The width of the liquid returning groove 163 may be 0.1mm to 0.5mm, preferably 0.2mm to 0.4 mm. In addition, the first fin 161 at the bottom of fig. 6 is not cut off by the liquid returning groove 163, so as to capture the liquid returning groove 163, increase the resistance of the liquid flowing downward, and improve the liquid leakage prevention effect.

In some embodiments, the leakage barrier 16 may include a cylindrical main body 164 and two wall portions 165 integrally combined with the bottom of the main body 164, and the two wall portions 165 may be symmetrically arranged along the circumferential direction of the main body 164. The leakage barriers 16 can be mounted against the upper end surface of the first inner flange 1123 by means of the two wall portions 165. The plurality of first fins 161 may be axially disposed in parallel on the body 163 and the two wall portions 164 at intervals. The at least one liquid returning groove 163 includes two liquid returning grooves 163, and the two liquid returning grooves 163 respectively extend from the vicinity of the bottoms of the two wall portions 164 upward to the top of the main body 164 along the axial direction, and are respectively communicated with a second liquid storage groove 1620. The inner wall surface of the main body 164 may further extend inward to form a protruding portion 166, and two lead through holes 1660 are longitudinally formed in the protruding portion 166 in a penetrating manner, and are respectively used for two electrode leads of the heat generating element 15 to pass through.
