1Productivity
If electromagnetic waves are used to heat the aerosol-generating article, then heating efficiency is improved, but power consumption increases
Solution Approach 1:
The patent introduces a heat-generating body as an intermediary between the microwave irradiation unit and the aerosol-generating article. The heat-generating body absorbs microwave energy and converts it to thermal energy, then transfers this heat to the article. This mediator approach allows more efficient energy transfer compared to direct microwave heating, thereby improving heating efficiency while managing power consumption requirements.
Solution Approach 2:
The patent employs a dielectric heater that changes its dielectric properties in response to microwave irradiation. By adjusting the dielectric constant and loss tangent of the heat-generating body, the system optimizes the absorption and conversion of microwave energy to thermal energy, enhancing heating efficiency while controlling the overall power consumption of the device.
