Abstract

An electronic cigarette includes an inhalation rod with a cavity, a mouthpiece assembly, an e-liquid accommodating assembly and an atomization assembly. The mouthpiece assembly, the e-liquid accommodating assembly and the atomization assembly are installed in the cavity of the inhalation rod. Between the mouthpiece assembly and the atomization assembly disposes a ventilation tube capable to guide the atomized e-liquid from the atomization assembly to the mouthpiece assembly. The mouthpiece assembly includes a filter. On an inner wall of the cavity of the inhalation rod along the axial direction thereof disposes a first mounting part. The filter or on other components fixing connected with the filter disposes a second mounting part. The first mounting part and the second mounting part are disposed adjacent to each other. The connection by mechanical mechanism does not need to use glue or other adhesive containing harmful ingredients.
