Abstract

An electronic cigarette sucking rod comprises a nozzle cover and a connecting module respectively inserted into opposite ends of the sucking cylinder, a conduit in the sucking cylinder, a liquid guiding component and an atomizing device between the liquid guiding component and the connecting module; the nozzle cover and the liquid guiding component respectively seal opposite ends of the liquid smoke compartment, opposite ends of the conduit are inserted into the through holes of the nozzle cover and the liquid guiding component, and a smoke passage extends through the liquid guiding component and the conduit. The liquid guiding component comprises a liquid separation seat and a liquid reservoir; the liquid separation seat comprises a seat body and a vent pipe; the vent pipe has its one end engaged with the conduit, and another end sleeved with the liquid reservoir and lead to the atomizing device; the liquid separation seat defines a liquid guiding hole.

Claims
