Abstract

The present invention discloses an electronic aerosol generation device and atomizer thereof, the atomizer comprises a shell, a fixing component, and an atomizing component. The atomizing component comprises a liquid conducting member and a heating element. The liquid conducting member is provided with an air guide hole running through itself longitudinally, and a liquid guide groove. The liquid guide groove may include a first sub-liquid guide groove and a second sub-liquid guide groove in communication with the first sub-liquid guide groove.
