Flavor inhaler, flavor inhaling system and smoking system

Abstract

This flavor inhaler comprises: a housing; a receptacle that is disposed within the housing, contains a consumable material including a smokable substance and heats the consumable material by a heating section; and a heat storage portion disposed between the housing and the receptacle and containing a heat storage material, wherein the heat storage portion includes an inner support member disposed on the receptacle side and an outer support member disposed on the housing side, and the layer of the heat storage material is disposed between the inner support member and the outer support member.

1 . A flavor inhaler comprising:
 a housing;   a receptacle that is disposed inside the housing, accommodates a consumable material including a smokable substance, and heats the consumable material by using a heating section; and   a heat storage portion that is disposed between the housing and the receptacle and that includes a heat storage material,   wherein the heat storage portion comprises an inner support member disposed toward the receptacle and an outer support member disposed toward the housing, and   wherein a layer of the heat storage material is disposed between the inner support member and the outer support member.   
     
     
         2 . The flavor inhaler according to  claim 1 , wherein the heat storage portion is filled with the heat storage material exceeding 20% of a volume of a space defined by the inner support member and the outer support member. 
     
     
         3 . The flavor inhaler according to  claim 1 , wherein a thermal conductivity of the inner support member is lower than a thermal conductivity of the outer support member. 
     
     
         4 . The flavor inhaler according to  claim 1 , wherein a thermal conductivity of the inner support member at 25° C. is 0.3 [W/(m·K)] or lower. 
     
     
         5 . The flavor inhaler according to  claim 1 , wherein a thermal conductivity of the outer support member at 25° C. is 1.0 [W/(m·K)] or higher. 
     
     
         6 . The flavor inhaler according to  claim 1 , wherein the inner support member contains resin. 
     
     
         7 . The flavor inhaler according to  claim 1 , wherein the inner support member is disposed integrally with an outer wall of the receptacle. 
     
     
         8 . The flavor inhaler according to of  claim 1 , wherein the outer support member contains metal. 
     
     
         9 . The flavor inhaler according to  claim 8 , wherein the outer support member is a metal pipe extending along a central axis of the housing. 
     
     
         10 . The flavor inhaler according to  claim 1 , wherein the outer support member is disposed in contact with an inner side surface of the housing. 
     
     
         11 . The flavor inhaler according to  claim 1 , further comprising a heat diffuser that is disposed inside the housing, has a higher thermal conductivity than the housing, and is in contact with the outer support member. 
     
     
         12 . The flavor inhaler according to  claim 1 ,
 wherein the flavor inhaler comprises the heating section, and   wherein the heating section is disposed within the receptacle.   
     
     
         13 . The flavor inhaler according to  claim 1 , wherein the heat storage material undergoes a phase transition at a temperature between 40° C. and 50° C. 
     
     
         14 . The flavor inhaler according to of  claim 1 , wherein the heat storage material contains paraffin. 
     
     
         15 . The flavor inhaler according to  claim 14 , wherein the heat storage material contains normal paraffin with a carbon number of 21, 22, or 23. 
     
     
         16 . The flavor inhaler according to  claim 1 , further comprising:
 a control device and a temperature sensor,   wherein the temperature sensor detects a temperature of the heat storage portion, and   wherein the control device allows the consumable material to be heated only when the temperature of the heat storage portion is lower than or equal to a predetermined temperature or is lower than the predetermined temperature.   
     
     
         17 . A flavor inhaling system comprising:
 a recharger comprising a holding section and a recharging section, the holding section holding the flavor inhaler according to  claim 1 , the recharging section recharging the flavor inhaler held by the holding section; and   the flavor inhaler.   
     
     
         18 . The flavor inhaling system according to  claim 17 , wherein an area of the recharger that is in contact with the housing of the flavor inhaler has a thermal conductivity of 1 [W/(m·K)] or higher at 25° C. 
     
     
         19 . A smoking system comprising:
 the flavor inhaler according to  claim 1 ; and   a consumable material including a smokable substance.
