Main body unit of aerosol generator, aerosol generator, and non-combustion-type inhaler

Abstract

This main body unit of an aerosol generator includes a housing that has a cartridge housing space provided therein, wherein the housing includes a pair of main surface portions, a circumferential wall portion that connects the pair of main surface portions and has a plurality of corner portions provided thereat, a first air inlet that takes air into the cartridge housing space from between the pair of main surface portions or the adjacent corner portions of the circumferential wall portion, and a second air inlet that takes air into the cartridge housing space from the corner portion of the circumferential wall portion.

What is claimed is: 
     
         1 . A main body unit of an aerosol generator comprising a housing that has a cartridge housing space provided therein, wherein
 the housing includes:   a pair of main surface portions:   a circumferential wall portion that connects the pair of main surface portions and has a plurality of corner portions provided thereat;   a first air inlet that takes air into the cartridge housing space from between the pair of main surface portions or the adjacent corner portions of the circumferential wall portion; and   a second air inlet that takes air into the cartridge housing space from the corner portion of the circumferential wall portion.   
     
     
         2 . The main body unit of an aerosol generator according to  claim 1 , wherein
 the housing includes:   an inner case; and   an outer case that covers the inner case and includes an exposed portion at which a part of the inner case is exposed at the corner portion, and   the second air inlet is formed in a gap between the inner case and the outer case in the exposed portion.   
     
     
         3 . The main body unit of an aerosol generator according to  claim 2 , wherein
 an edge part of the exposed portion is curved.   
     
     
         4 . The main body unit of an aerosol generator according to  claim 1 , wherein
 the housing includes a protruding portion around the second air inlet.   
     
     
         5 . The main body unit of an aerosol generator according to  claim 2 , wherein
 the housing includes a protruding portion around the second air inlet, and   the protruding portion is formed by the outer case.   
     
     
         6 . The main body unit of an aerosol generator according to  claim 1 , wherein
 the housing includes:   a communication hole in communication with the cartridge housing space;   a first air flow path that causes the first air inlet to be in communication with the communication hole; and   a second air flow path that causes the second air inlet to be in communication with the communication hole, and   the first air flow path has lower airflow resistance than the second air flow path.   
     
     
         7 . The main body unit of an aerosol generator according to  claim 6 , wherein
 the first air flow path has a flow path length to the communication hole smaller than that of the second air flow path.   
     
     
         8 . The main body unit of an aerosol generator according to  claim 6 , wherein
 the communication hole has a flow path cross-sectional area smaller than either the first air inlet or the second air inlet.   
     
     
         9 . The main body unit of an aerosol generator according to  claim 1 , wherein
 the housing includes:   an opening formed between the adjacent corner portions of the circumferential wall portion; and   a cover member provided in the opening, and   the first air inlet is formed in a gap between the cover member and the opening.   
     
     
         10 . An aerosol generator comprising:
 a main body unit according to  claim 1 ; and   a cartridge that stores an aerosol source and is inserted into the cartridge housing space of the main body unit.   
     
     
         11 . A non-combustion-type inhaler comprising:
 an aerosol generator according to claim  10 ; and   a flavor source container attached to the aerosol generator.
