    Abstract: An inhalation device controller is configured to control an atomizer including a container configured to hold an aerosol source of a liquid, a heater, and a transport portion configured to transport the aerosol source from the container to a heating area by the heater. The controller includes a control circuit configured to monitor a physical amount correlated with a temperature of the heater and configured to control power to be supplied to the atomizer such that the physical amount under monitoring approaches a target value. The target value is set such that the temperature of the heater during heating of the aerosol source falls within a range of 210° C. to 230° C.

  • Patent number: 11116256
    Abstract: An inhalation device controller includes a holder that holds an atomizer including a heater for atomizing an aerosol source, and a processor. Upon detecting an atomization request, the processor executes first determination processing of determining a remaining amount of the aerosol source in the atomizer using a first algorithm, and upon detecting an atomization request after the execution of the first determination processing, executes second determination processing of determining presence/absence of the aerosol source in the atomizer using a second algorithm. Even if it is determined by the first determination processing that the remaining amount is larger than 0, if aerosol source absence is determined by the second determination processing, the processor outputs the aerosol source absence as a final determination result, and inhibits a supply of power to the heater.
