  • 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.
