Aerosol generating apparatus including a plurality of heaters and aerosol generating article used together therewith

Abstract

Provided is an aerosol generating apparatus including a housing that forms an accommodation space in which an aerosol generating article is accommodated, a heater unit that heats an aerosol generating article accommodated in the accommodating space, and a control unit that adjusts a temperature of the heater unit. The heater unit includes a first heater unit and a second heater unit disposed to heat different positions of the aerosol generating article, respectively, and the control unit controls to separately adjust the temperature of the first heater unit and the second heater unit. The aerosol generating apparatus according to an embodiment of the present invention may generate various components or amounts of aerosol according to consumer's preference even for one aerosol generating article.

1 . An aerosol generating apparatus, comprising:
 a housing that forms an accommodation space in which an aerosol generating article is accommodated;   a heater unit that heats an aerosol generating article accommodated in the accommodating space; and   a control unit that adjusts a temperature of the heater unit,   wherein the heater unit includes a first heater unit and a second heater unit disposed to heat different positions of the aerosol generating article, respectively, and   the control unit controls to separately adjust the temperature of the first heater unit and the second heater unit.   
     
     
         2 . The aerosol generating apparatus of  claim 1 , wherein the aerosol generating article includes a first filter segment, a second filter segment, and a cavity segment,
 the cavity segment is formed by the first filter segment and the second filter segment,   the cavity segment is filled with a tobacco granule, and   the first filter segment is located upstream of the cavity segment and includes an aerosol forming agent.   
     
     
         3 . The aerosol generating apparatus of  claim 2 , wherein the first filter segment and the cavity segment of the aerosol generating article are accommodated in the accommodation space of the aerosol generating apparatus,
 the first heater unit is located to heat the first filter segment, and   the second heater unit is located to heat the cavity segment.   
     
     
         4 . The aerosol generating apparatus of  claim 3 , wherein the first heater unit is driven in a smoky mode or a smokeless mode,
 in the smoky mode, the first heater unit is heated to maintain a temperature range of 180° C. to 240° C., and   in the smokeless mode, the first heater unit is not heated.   
     
     
         5 . The aerosol generating apparatus of  claim 3 , wherein the second heater unit is driven in one of a strong mode, a medium mode, and a weak mode,
 in the strong mode, the second heater unit is heated to maintain a temperature range of 200° C. to 260° C.,   in the medium mode, the second heater unit is heated to maintain a temperature range of 160° C. to 200° C., and   in the weak mode, the second heater unit is heated to maintain a temperature range of 150° C. to 180° C.   
     
     
         6 . The aerosol generating apparatus of  claim 5 , wherein when the temperature of the first heater unit is less than 100° C., the second heater unit is driven in the strong mode. 
     
     
         7 . The aerosol generating apparatus of  claim 1 , wherein the first heater unit and the second heater unit are driven in a form of being reheated when they are out of a set range after being initially preheated. 
     
     
         8 . The aerosol generating apparatus of  claim 4 , further comprising:
 a switch that is disposed on an outer wall surface of the housing,   wherein the switch sets the smoky mode or the smokeless mode for the first heater unit and sets the strong mode, the medium mode, or the weak mode for the second heater unit.
