Aerosol-generating device and aerosol-generating system

Abstract

Proposed is an aerosol-generating device or aerosol-generating system including a housing having an inlet hole in which an aerosol-generating article is placed, a liquid storage part configured to store a liquid, and a heating part configured to heat the liquid storage part and the inlet hole selectively.

What is claimed is: 
     
         1 . An aerosol-generating device comprising:
 a housing;   an inlet hole formed on one side of the housing, the inlet hole through which an aerosol-generating article enters;   a liquid storage part placed to be close to the inlet hole, the liquid storage part configured to store a liquid; and   a heating part configured to heat the liquid storage part and the inlet hole such that the aerosol-generating article is heated,   wherein the heating part heats the inlet hole or both the liquid storage part and the inlet hole.   
     
     
         2 . The device of  claim 1 , wherein the heating part comprises:
 a first heater configured to heat the liquid storage part; and   a second heater configured to heat the inlet hole,   when both the first and second heaters are enabled to operate, the second heater is enabled to be heated to a first temperature, and   when the second heater is enabled to operate, the second heater is enabled to be heated to a second temperature higher than the first temperature.   
     
     
         3 . The device of  claim 2 , wherein the first temperature is 120 degrees or higher, and
 the second temperature is higher than the first temperature by at least 40 degrees or more.   
     
     
         4 . The device of  claim 2 , wherein the first temperature is in a range of 120 to 200 degrees, and
 the second temperature is in a range of 160 to 280 degrees.   
     
     
         5 . The device of  claim 2 , wherein when an amount of the liquid in the liquid storage part is smaller than a preset amount, the second heater is heated. 
     
     
         6 . The device of  claim 2 , wherein in the housing, a detection sensor configured to detect the aerosol-generating article entering through the inlet hole is placed, and
 when the detection sensor detects the preset aerosol-generating article, the second heater is heated.   
     
     
         7 . An aerosol-generating system comprising:
 a housing;   an inlet hole formed on one side of the housing;   a liquid storage part installed in the housing, the liquid storage part configured to store a liquid to be converted into an aerosol when heated;   a heating part configured to heat only the inlet hole or both the liquid storage part and the inlet hole; and   an aerosol-generating article entering through the inlet hole, the aerosol-generating article comprising a medium part filled with 10% or more of a moisturizer and placed in a position corresponding to a portion heated by the heating part.   
     
     
         8 . The system of  claim 7 , wherein the aerosol-generating article comprises a cooling part formed on one side of the medium part and having a plurality of perforated holes. 
     
     
         9 . The system of  claim 8 , wherein the cooling part comprises a plurality of segments placed in succession, the segments being hollow and having the plurality of perforated holes extending through an interior and an exterior thereof. 
     
     
         10 . The system of  claim 8 , further comprising a detection sensor configured to detect the aerosol-generating article entering through the inlet hole,
 wherein when the detection sensor detects the aerosol-generating article comprising the cooling part, the heating part is enabled to operate such that only the inlet hole is heated.   
     
     
         11 . The system of  claim 8 , wherein the heating part comprises:
 a first heater configured to heat the liquid storage part; and   a second heater configured to heat the inlet hole,   when both the first and second heaters are enabled to operate, the second heater is enabled to be heated to a first temperature, and   when the second heater is enabled to operate, the second heater is enabled to be heated to a second temperature higher than the first temperature.   
     
     
         12 . The system of  claim 11 , wherein the second temperature is in a range of 160 to 280 degrees, and
 air enters the cooling part through the perforated holes, so the aerosol generated in the medium part is mixed with the air, diluted by 10% or more, and cooled.
