Heater assembly for aerosol generating device and aerosol generating device including the same

Abstract

A heater assembly for an aerosol generating device, includes a heater having formed therein an accommodating space in which an aerosol generating article is accommodated, the heater being configured to heat the aerosol generating article accommodated in the accommodating space, and a heater accommodating portion connected to the heater so that aerosols generated from an aerosol generating material flow to the aerosol generating article accommodated in the accommodating space, and insert-injected with the heater.

1 . A heater assembly for an aerosol generating device, comprising:
 a heater having formed therein an accommodating space in which an aerosol generating article is accommodated, the heater being configured to heat the aerosol generating article accommodated in the accommodating space; and   a heater accommodating portion connected to the heater so that aerosols generated from an aerosol generating material flow to the aerosol generating article accommodated in the accommodating space, and insert-injected with the heater.   
     
     
         2 . The heater assembly of  claim 1 , wherein the heater and the heater accommodating portion are integrally formed. 
     
     
         3 . The heater assembly of  claim 1 , wherein at least one of the heater or the heater accommodating portion comprises a protruding portion protruding towards the remaining one. 
     
     
         4 . The heater assembly of  claim 1 , wherein the heater comprises an extending portion extending in a direction crossing a direction in which the heater accommodating portion extends. 
     
     
         5 . The heater assembly of  claim 4 , wherein the heater accommodating portion is connected to the heater to surround an entire outer side of the extending portion. 
     
     
         6 . The heater assembly of  claim 4 , wherein an inner surface of the heater, facing the accommodating space, and an inner surface of the heater accommodating portion, facing the accommodating space, are connected to each other through a continuous surface. 
     
     
         7 . The heater assembly of  claim 1 , wherein the heater comprises:
 a first extending portion extending in a second direction crossing a first direction in which the heater accommodating portion extends; and   a second extending portion extending in the first direction from the first extending portion.   
     
     
         8 . The heater assembly of  claim 1 , wherein a sealing ring arranged to surround the heater and the heater accommodating portion together. 
     
     
         9 . The heater assembly of  claim 1 , wherein the heater extends in a direction in which the heater accommodating portion extends to be insert-injected with the heater accommodating portion. 
     
     
         10 . The heater assembly of  claim 1 , wherein the heater comprises:
 a film configured to generate heat when power is applied; and   a heat transfer pipe located inside the film and configured to transfer the heat generated in the film to the aerosol generating article accommodated in the accommodating space.   
     
     
         11 . The heater assembly of  claim 10 , wherein the heat transfer pipe is insert-injected with the heater accommodating portion. 
     
     
         12 . The heater assembly of  claim 1 , wherein the heater accommodating portion comprises an aerosol inlet hole connected to a chamber that is a space in which the aerosols are generated. 
     
     
         13 . An aerosol generating device comprising:
 the heater assembly for an aerosol generating device, according to  claim 1 , accommodating the aerosol generating article and configured to heat the aerosol generating article; and   a cartridge storing the aerosol generating material and connected to the heater assembly to allow the generated aerosols to move to the aerosol generating article.   
     
     
         14 . The aerosol generating device of  claim 13 , wherein the cartridge comprises:
 a storage in which the aerosol generating material is stored;   a heating unit configured to absorb the aerosol generating material stored in the storage and heat the aerosol generating material; and   a chamber accommodating the heating unit and providing a space in which the aerosols are generated.   
     
     
         15 . The aerosol generating device of  claim 13 , wherein the aerosols generated in the cartridge are externally discharged through the aerosol generating article accommodated in the heater assembly.
