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; a cartridge that includes an aerosol forming agent; a cartridge heater unit that heats the cartridge; and a control unit that controls the aerosol generating apparatus to operate in a mode set among a smoky mode and a smokeless mode.

First claim

The invention claimed is:

1 . An aerosol generating apparatus, comprising:
a housing including an accommodation space, the accommodation space configured to accommodate an aerosol generating article; a heater unit configured to heat the aerosol generating article accommodated in the accommodation space; a cartridge that comprises an aerosol forming agent; a cartridge heater unit configured to heat the cartridge; and a control unit configured to control, by controlling at least one from among the heater unit and the cartridge heater unit, the aerosol generating apparatus to operate in a mode set among a smoky mode and a smokeless mode, wherein the control unit is further configured to control the heater unit to operate in one of a strong mode, a medium mode, and a weak mode by varying a heating temperature for the aerosol generating article.

2 . A system comprising:
the aerosol generating apparatus of claim 1 ; and the aerosol generating article, wherein the aerosol generating article comprises a tobacco rod, the tobacco rod comprises a first filter segment, a second filter segment, and a cavity segment formed by the first filter segment and the second filter segment, and the cavity segment is filled with a tobacco granule.

3 . The system of claim 2 , wherein the aerosol generating article further comprises a filter rod located downstream of the tobacco rod, and
the filter rod comprises a cooling segment and a mouthpiece segment.

4 . The aerosol generating apparatus of claim 1 , wherein the control unit is configured to operate both the heater unit and the cartridge heater unit or operate the cartridge heater unit, without operating the heater unit, in response to a determination that the set mode is the smoky mode.

5 . The aerosol generating apparatus of claim 1 , wherein the control unit is configured to control the heater unit maintain heating at:
a temperature of 200 to 260° C. in the strong mode; a temperature of 160 to 200° C. in the medium mode; and a temperature of 150 to 180° C. in the weak mode.

6 . An aerosol generating apparatus comprising:
a housing including an accommodation space, the accommodation space configured to accommodate an aerosol generating article; a heater unit configured to heat the aerosol generating article accommodated in the accommodation space; a cartridge that comprises an aerosol forming agent; a cartridge heater unit configured to heat the cartridge; and a control unit configured to control, by controlling at least one from among the heater unit and the cartridge heater unit, the aerosol generating apparatus to operate in a mode set among a smoky mode and a smokeless mode, wherein the control unit is configured to operates the heater unit, without operating the cartridge heater unit, in response to a determination that the set mode is the smokeless mode.

7 . The aerosol generating apparatus of claim 6 , wherein the heater unit is heated to maintain a temperature of 200 to 260° C.

8 . The system of claim 2 , wherein the heater unit is configured to heat only the cavity segment from among the cavity segment, the first filter segment, and the second filter segment.

9 . The aerosol generating apparatus of claim 1 , wherein the control unit is further to control the heater unit to reheat based on a temperature of the heater unit being outside a set temperature range after the heater unit is initially preheated.

10 . The aerosol generating apparatus of claim 1 , wherein the aerosol generating apparatus further comprises:
a switch on an outer wall surface of the housing, wherein the switch is configured to set the smoky mode and the smokeless mode, and in a case where the smoky mode is selected, set any one of the strong mode, the medium mode, and the weak mode.
