Problems solved by technology
[0003] When the aerosol generating device includes multiple heaters, it is unavoidable that the heater that heats up first affects the heater that heats up later
For example, when the aerosol generating device has two heaters, when the first heater is heated and the second heater is heated, the aerosol generating device that rises as the first heater is heated temperature, causing the heating start temperature of the second heater to be higher than normal temperature, when heating the second heater in this state, not enough heat energy is applied to the aerosol-generating substrate used to generate the aerosol, which may occur Insufficient amount of atomization

An embodiment of the present invention provides an aerosol generation device comprising: a first heater for heating a cigarette inserted in a first portion of the aerosol generation device; a second heater for heating a liquid composition stored in a cartridge detachably attached to a second portion of the aerosol generation device; and a controller for controlling power supplied to the first heater and the second heater, wherein the controller controls power supplied to the second heater on the basis of a heating pattern in which the first heater is heated.
Description
technical field [0001] The present invention relates to an aerosol generating device having a first heater and a second heater and a method of controlling electric power of the first heater and the second heater of the aerosol generating device, and more particularly relates to an aerosol generating device with A method for effectively controlling electric power supplied to a first heater and a second heater included in an aerosol generating device, and an aerosol generating device realized by the method. Background technique [0002] Recently, there has been an increasing demand for alternative methods to overcome the disadvantages of conventional cigarettes. For example, there is an increasing demand for a method of generating an aerosol by heating an aerosol-generating substance in a cigarette, not by burning a cigarette. Therefore, research on heated cigarettes or heated aerosol generating devices has become increasingly active. [0003] When the aerosol generating dev...
