Aerosol generator and flavor aspirator

Abstract

An aerosol generator ( 3 ) according to the present invention is provided with: an aerosol source storage part ( 31 ) that includes a liquid first aerosol source and a first absorber for absorbing the first aerosol source, the first absorber including a tobacco material; and, an aerosol generation part ( 32 ) that includes a liquid second aerosol source and a second absorber for absorbing the second aerosol source, the second absorber including a tobacco material and contacting the first absorber. The speed at which the second absorber sucks up the first aerosol source is higher than the speed at which the first absorber sucks up the first aerosol source.

What is claimed is: 
     
         1 . An aerosol generator comprising:
 an aerosol source storage unit including a liquid first aerosol source and a first absorber having the first aerosol source absorbed, the first absorber including a tobacco material; and   an aerosol generation unit including a liquid second aerosol source and a second absorber having the second aerosol source absorbed, the second absorber including a tobacco material and being in contact with the first absorber,   a rate at which the second absorber absorbs the first aerosol source being higher than a rate at which the first absorber absorbs the first aerosol source.   
     
     
         2 . The aerosol generator according to  claim 1 , wherein the first absorber has a shape extending in one direction, and the first absorber and the second absorber are arranged in a length direction of the first absorber. 
     
     
         3 . The aerosol generator according to  claim 2 , wherein an interface between the first absorber and the second absorber protrudes at a central portion thereof toward the second absorber. 
     
     
         4 . The aerosol generator according to  claim 2 , further comprising a cylindrical body accommodating the aerosol source storage unit and the aerosol generation unit, wherein the aerosol source storage unit and the aerosol generation unit are arranged in a length direction of the cylindrical body. 
     
     
         5 . The aerosol generator according to  claim 4 , wherein the cylindrical body has a smaller diameter of an opening closer to the aerosol generation unit than an inner diameter at a position of the aerosol source storage unit. 
     
     
         6 . The aerosol generator according to  claim 2 , further comprising a heater including a heating surface facing the first absorber with the second absorber interposed therebetween. 
     
     
         7 . The aerosol generator according to  claim 6 , wherein the heater includes one or more grooves provided in the heating surface, one or more through holes communicating with the one or more grooves, or both. 
     
     
         8 . The aerosol generator according to  claim 6 , wherein the second absorber is tapered towards the heating surface, and the heating surface has a smaller dimension in a direction perpendicular to the length direction of the first absorber than that of the first absorber. 
     
     
         9 . The aerosol generator according to  claim 2 , further comprising a heater including a linear heating portion facing the first absorber with the second absorber interposed therebetween. 
     
     
         10 . The aerosol generator according to  claim 9 , wherein the second absorber has a surface on a side of the heating portion, the surface on the side of the heating portion being seen flat in a cross section parallel to the length direction of the first absorber and the length direction of the heating portion, and being seen protruding at a central portion thereof in a cross section parallel to the length direction of the first absorber and perpendicular to the length direction of the heating portion. 
     
     
         11 . The aerosol generator according to  claim 2 , further comprising a cylindrical body accommodating the aerosol source storage unit, wherein the cylindrical body has a smaller diameter of an opening closer to the aerosol generation unit than an inner diameter at a position away from the opening, and the aerosol generation unit protrudes outside the cylindrical body at a position of the opening. 
     
     
         12 . The aerosol generator according to  claim 11 , further comprising a coiled heater wound around the aerosol generation unit. 
     
     
         13 . The aerosol generator according to  claim 1 , wherein the first absorber has a pillar shape, and the second absorber surrounds the first absorber. 
     
     
         14 . The aerosol generator according to  claim 13 , further comprising a linear heater surrounding the first absorber with the second absorber interposed therebetween. 
     
     
         15 . The aerosol generator according to  claim 13 , further comprising a cylindrical heater surrounding the first absorber with the second absorber interposed therebetween. 
     
     
         16 . The aerosol generator according to  claim 15 , wherein an inner surface of the heater includes one or more grooves each extending from one opening of the heater to another opening of the heater. 
     
     
         17 . A flavor inhaler comprising:
 the aerosol generator according to  claim 6 ;   a power supply supplying electric power to the heater; and   a case including a mouthpiece at one end, and accommodating the aerosol generator and the power supply.   
     
     
         18 . The flavor inhaler according to  claim 17 , wherein the aerosol generator is positioned between the power supply and the mouthpiece. 
     
     
         19 . The flavor inhaler according to  claim 18 , wherein the case includes an air inlet at a position between the power supply and the aerosol generator, and the aerosol generator and the case form a flow path therebetween from the air inlet to the mouthpiece.
