The invention discloses an atomization assembly of an electronic cigarette and the electronic cigarette adopting the atomization assembly. The atomization assembly comprises an atomization core sleeve, an oil guiding cover, a U-shaped induction metal piece, oil guiding cotton and an induction coil, wherein the oil guiding cover is detachably arranged at the end of the atomization core sleeve, theoil guiding cover is provided with a guiding sleeve, the inner portion of the guiding sleeve is communicated, the guiding sleeve extends in the direction away from the atomization core sleeve, the induction metal piece is arranged in the atomization core sleeve, one end of the oil guiding cotton is located in the induction metal piece, the other end of the oil guiding cotton is located in the guiding sleeve, and the induction coil sleeves the atomization core sleeve. The atomization assembly adopting the structure has the advantages that the thermal energy conversion efficiency is high, the atomization effect of smoke oil can be improved, and the installation space is saved. The electronic cigarette adopting the atomization assembly not only has the advantages of the atomization assembly,but also has the advantages that the structure is simple, the cost is low, the assembly and disassembly are convenient, environmental friendliness is achieved, and the requirement of a large amount ofsmoke can be met.
