Wherein, the oily body of hard oil guide has better lock oily performance than the flexible oily body of leading, and the oily body of flexible oil guide has better oily stock solution performance of leading than the oily body of hard oil guide, through the combination between them for the heat-generating body when using, has better oil leak protection performance of leading on the whole.

Specifically, the aperture of the first air passing hole 211 is larger than the outer diameter of the upper end of the atomizing support 31, and an annular protrusion 213 is convexly formed in the middle of the first air passing hole 211, and when the upper end of the atomizing support 31 is inserted into the first air passing hole 211, the annular protrusion 213 elastically abuts against the outer wall of the upper end of the atomizing support 31; thereby realizing the sealing connection between the atomizing support 31 and the inner wall of the first air passing hole 211 and ensuring the sealing performance of the atomizing channel 34; in addition, since the annular protrusion 213 is located at the middle of the first air passing hole 211, it is preferably disposed adjacent to the upper end of the first air passing hole 211. Because the aperture of first air passing hole 211 is greater than the external diameter of the upper end of atomizing support 31, there is a clearance between the internal perisporium of first air passing hole 211 and the external perisporium of the upper end of atomizing support 31, make atomizing support 31 in the equipment process of inserting first air passing hole 211, the air in stock solution chamber 11 can be discharged through this clearance, the air compression volume in stock solution chamber 11 has been reduced, thereby avoid when atomizing subassembly and suction nozzle subassembly 20 assemble, cause the excessive oil guide hole 311 of atomizing liquid to extrude because of the inside air of too big compression stock solution chamber 11, cause atomizing core 30 weeping phenomenon.
