Abstract
This non-combusting flavor inhaler is provided with a control unit which, as an instruction to a battery, outputs to the battery a prescribed instruction instructing the battery that the amount of aerosol vaporized by a vaporizer unit should fall within a desired range. The control unit stops power supply from the battery to the vaporizer unit once a prescribed period has elapsed since the start of supplying power to the vaporizer unit. The prescribed period is shorter than the upper limit value of a standard puff period, which is derived from a statistic of the user's puff period.
Claims19
A non-combustible inhaler comprising:
- an atomizer configured to atomize an aerosol source;
- a battery configured to accumulate power to be supplied to the atomizer;
- a sensor configured to detect a puff action;
- and
- circuitry configured to
- detect that a puff action has occurred based on an output of the sensor;
- identify, in a case of detecting the puff action, a duty ratio for suppling pulse-width-modulated power to the atomizer based on a remaining amount of power of the battery;
- initiate supplying pulse-width-modulated power from the battery to the atomizer at a first duty ratio in a case that it is detected that the puff action has occurred and the remaining amount of power of the battery is a first value;
- initiate supplying the pulse-width-modulated power from the battery to the atomizer at a second duty ratio, which is different from the first duty ratio, in a case that it is detected that the puff action has occurred and the remaining amount of power of the battery is a second value, which is different from the first value;
- and
- stop supplying the pulse-width-modulated power from the battery to the atomizer after a predetermined time has elapsed from initiating supplying the pulse-width-modulated power from the battery to the atomizer, wherein
- the circuitry is configured to acquire an upper limit time value based on stored data indicating a plurality of puff actions previously performed by at least one of a plurality of users of the non-combustible inhaler, and
- the predetermined time is a time that is less than the acquired upper limit time value of the puff period, wherein
- the circuitry is configured to store puff period data from puff actions performed by the at least one of the plurality of users, derive the upper limit time value from statistics of the stored puff period data, and set the predetermined time based on the derived upper limit time value.
