Abstract

An atomization assembly configured to be combined with a battery assembly to form an electronic cigarette comprises a mouthpiece and a body detachable with the mouthpiece. The body includes an open end to discharge smoke into the mouthpiece, an oil storage cavity for storing tobacco oil is defined inside the body, a receiving groove is defined at the open end, an filler hole connected to the oil storage cavity is defined on a bottom wall of the receiving groove, and an elastomeric seal for sealing up the filler hole is received in the receiving groove. By implementing the filler hole, it is easier to add the tobacco oil, and by implementing the elastomeric seal, the tobacco oil can be avoided leaking out. Further, the atomization assembly is provided with simple structure, compact connection and easy assembly.
