Problems solved by technology

However, it has been found that initially supplying high or maximum power to the heater to rapidly increase the temperature of the cartridge is generally not the best solution
For example, heating can be inefficient, causing energy loss due to the inability of the barrel material to absorb heat effectively
Additionally, the cartridge or its parts or the aerosol-forming substrate contained within the cartridge may overheat

Abstract

A method of controlling a heater in an aerosol-generating device, which has a heater comprising at least one heating element which heats an aerosol-forming substrate, and a power source which providespower to the heating element. The method steps are: controlling power provided to the heating element such that in a first phase power is provided to increase the temperature of the heating element from an initial temperature to a first temperature, and in a second phase power is provided to decrease the temperature of the heating element below the first temperature to a second temperature. The power provided to the heating element during the first phase is increased at least once during the duration of the first phase; and aerosol is produced during the second phase.

Description

technical field [0001] The present invention relates to an aerosol-generating device comprising a cartridge containing an aerosol-forming substrate and to a method for controlling a heater of the aerosol-generating device. [0002] In particular, the present invention relates to a method of controlling the heater of an aerosol-generating device during the initial phase, wherein a cartridge containing an aerosol-forming substrate is heated to a temperature at which aerosols are generated as quickly as possible while avoiding aerosol formation Overheating of the substrate, and unnecessary energy loss due to the inability of the barrel material to absorb heat effectively. Background technique [0003] It is generally desirable for an aerosol-generating device to generate an aerosol with desired characteristics as soon as possible after activation of the device. In order for an aerosol generating device to have a satisfactory consumer experience, "time to first inhalation" is b...
