Heater module for aerosol generating device, cartridge for aerosol generating device, and aerosol generating device

Abstract

A heater module for an aerosol generating device includes a heater module body detachably coupled to a cartridge which includes an aerosol generating material and having an inlet hole through which external air is introduced, a wick including a first surface that faces the inlet hole and extends in a direction crossing another direction in which air is introduced through the inlet hole and arranged in the heater module body to absorb the aerosol generating material, and a heater provided on the first surface of the wick to face the inlet hole and heating the aerosol generating material absorbed in the wick.

What is claimed is: 
     
         1 . A heater module for an aerosol generating device, the heater module comprising:
 a heater module body detachably coupled to a cartridge which includes an aerosol generating material and having an inlet hole through which external air is introduced;   a wick including a first surface that faces the inlet hole and extends in a direction crossing another direction in which air is introduced through the inlet hole and arranged in the heater module body to absorb the aerosol generating material; and   a heater arranged on the first surface of the wick to face the inlet hole and heating the aerosol generating material absorbed in the wick.   
     
     
         2 . The heater module of  claim 1 , wherein
 the wick further includes a second surface arranged in an opposite direction to the first face and facing the cartridge, and a third surface facing a side wall of the heater module body, and   the first surface has a size larger than a size of at least one of the second surface and the third surface.   
     
     
         3 . The heater module of  claim 1 , wherein the wick includes a contact member protruding toward the cartridge to absorb the aerosol generating material stored in the cartridge. 
     
     
         4 . The heater module of  claim 3 , wherein the heater module body includes an aerosol generating material inlet through which the contact member passes and the aerosol generating material is introduced. 
     
     
         5 . The heater module of  claim 3 , wherein the contact member includes a first contact member and a second contact member arranged with a discharge passage, through which a generated aerosol is discharged, therebetween. 
     
     
         6 . The heater module of  claim 1 , wherein the wick surrounds at least a part of a discharge passage through which a generated aerosol is discharged. 
     
     
         7 . The heater module of  claim 1 , wherein the heater module body includes a discharge passage through which a generated aerosol is discharged, and a partition wall surrounding the discharge passage. 
     
     
         8 . The heater module of  claim 1 , wherein the heater module body includes a discharge passage that is placed at a position corresponding to the inlet hole and extends in a direction in which air is introduced through the inlet hole. 
     
     
         9 . The heater module of  claim 1 , further comprising a heater terminal arranged on the heater module body to face the first surface and electrically connected to the heater. 
     
     
         10 . The heater module of  claim 9 , wherein the heater terminal includes:
 a first heater terminal member which is in contact with the heater and of which at least a part has a curved surface;   a second heater terminal member connected to the first heater terminal member; and   a third heater terminal member connected to the second heater terminal member and electrically connected to a battery.   
     
     
         11 . The heater module of  claim 1 , further comprising a recognition terminal arranged on the heater module body and electrically connected to the cartridge. 
     
     
         12 . The heater module of  claim 11 , wherein the recognition terminal includes:
 a recognition terminal body coupled to the heater module body; and   a cartridge contact member that is in contact with the cartridge and elastically and movably coupled to the recognition terminal body.   
     
     
         13 . A cartridge for an aerosol generating device, the cartridge comprising:
 a storage fluidly connected to an internal space of the heater module for the aerosol generating device of  claim 1  to store the aerosol generating material;   a transfer portion configured to transfer the aerosol generating material stored in the storage to the heater module for the aerosol generating device; and   a recognition contact portion arranged in a position spatially separated from the transfer portion and electrically connected to the heater module for the aerosol generating device.   
     
     
         14 . The cartridge of  claim 13 , further comprising:
 a discharge passage through which an aerosol generated as the aerosol generating material is heated passes through the storage and is discharged,   wherein the transfer portion includes a first transfer portion and a second transfer portion with the discharge passage therebetween.   
     
     
         15 . An aerosol generating device comprising:
 an aerosol generating device body detachably coupled to the heater module for the aerosol generating device of  claim 1 ;   a battery arranged inside the aerosol generating device body and electrically connected to the heater module for the aerosol generating device; and   a processor configured to control power supplied from the battery to the heater module for the aerosol generating device.
