Atomization device and atomization core thereof

Abstract

The invention discloses an atomization device and atomization core thereof, the atomization core comprises a liquid conducting member and a heating element. The liquid conducting member is provided with an airflow hole running through itself longitudinally, and at least one liquid storage groove. The liquid storage groove is located on the outer periphery of the airflow hole, and the liquid storage groove includes at least one first sub-liquid storage groove and at least one second sub-liquid storage groove in communication with the first sub-liquid storage groove. The airflow hole is located at the center of the liquid conducting member, which can be close to the outlet of the atomization device, the aerosol generated by the atomization core has a shorter flow path and is less prone to affect the taste due to cooling, and it can effectively prevent the aerosol from condensing due to cooling during the flow process.
