Abstract
Provided is an aerosol generating device distributing and transmitting power from a battery to two heaters, wherein the aerosol generating device includes the battery, a first heater heating a first aerosol generating substrate, a second heater heating a second aerosol generating substrate, and a controller controlling power supplied from the battery to the first heater and the second heater, wherein the controller controls power to be supplied from the battery to the first heater and the second heater at different times.
Claims12
An aerosol generating device comprising:
- a battery;
- a first heater configured to heat a first aerosol generating substrate;
- a second heater configured to heat a second aerosol generating substrate;
- and
- a controller configured to control power to be supplied from the battery to the first heater and the second heater at different times,
- wherein the controller is further configured to:
- acquire a first duty cycle which is a duty cycle of power needed by the first heater in a current control period, and a second duty cycle which is a duty cycle of power needed by the second heater in the current control period,
- if a sum of the first duty cycle and the second duty cycle exceeds 100%, control the power supplied from the battery to satisfy one of the first duty cycle and the second duty cycle according to a current control mode among a plurality of control modes of the controller.
A method of controlling an aerosol generating device, the method comprising:
- acquiring a first duty cycle, which is a duty cycle of power needed by a first heater included in the aerosol generating device, and a second duty cycle, which is a duty cycle of power needed by a second heater included in the aerosol generating device;
- checking a current control mode among a plurality of control modes for controlling power supplied to the first heater and the second heater;
- and
- controlling power supplied from a battery to the first heater and the second heater at different times according to the checked control mode,
- wherein the controlling of the power comprises, if a sum of the first duty cycle and the second duty cycle exceeds 100%, controlling the power supplied from the battery to satisfy one of the first duty cycle and the second duty cycle according to the current control mode of the controller.
