Atomizing unit and non-combustion-heating-type flavor inhaling mechanism

Abstract

To prevent droplets formed by agglomeration of aerosol in an aerosol flow path from reaching the inside of a user's mouth, an atomizing unit includes an atomizing section configured to atomize an aerosol source, a tank configured to hold the aerosol source, and a liquid holding section disposed at a front end of the tank. The tank includes a flow path wall that defines at least part of an aerosol flow path, through which aerosol generated by atomizing of the aerosol source passes, and which extends in a first direction. The atomizing unit further includes a liquid evacuation section disposed in the aerosol flow path. The liquid holding section is in communication with the liquid evacuation section.

         3 . The atomizing unit according to  claim 2 ,
 wherein the liquid holding section includes a first concave-convex portion that is formed in a surface of the lid member which faces the front end of the tank, the first concave-convex portion being in communication with the liquid evacuation section and capable of holding the aerosol source.   
     
     
         4 . The atomizing unit according to  claim 2 ,
 wherein the lid member includes an opening which is in communication with the aerosol flow path to allow aerosol to pass through the opening.   
     
     
         5 . The atomizing unit according to  claim 3 ,
 wherein the first concave-convex portion includes first ridges extending in a second direction orthogonal to the first direction.   
     
     
         6 . The atomizing unit according to  claim 5 ,
 wherein gaps formed by the first ridges become smaller with distance from the aerosol flow path in the second direction.   
     
     
         7 . The atomizing unit according to  claim 5 ,
 wherein gaps formed by the first ridges become larger with distance from a surface of the lid member which faces the front end of the tank in the first direction.
