Abstract

This flavor-generating device includes: a circuit in which a power source, a first load for atomizing an aerosol source or heating a flavor source, and a second load different from the first load are electrically connected; a control unit configured so as to acquire a request for supply of power to each of the first load and the second load, and so as to control the circuit so that power is supplied from the power supply to each of the first load and the second load on the basis of the request; and a reducing means configured so that, when the control unit simultaneously acquires the request to the first load and the request to the second load, or when the control unit controls the circuit so that the supply of power to the first load and the supply of power to the second load are performed simultaneously, the electric power discharged from the power supply or the electric power amount is reduced to less than a maximum electric power for when the power supply discharges to the first load and the second load simultaneously or a maximum electric power amount.

Claims (20)

1. A flavor generating device comprising:

a circuit for electrically connecting an electric power source, a first load, and a second load which is different from the first load; and

a controller configured to control the circuit to control supply of electric power from the electric power source to the first load and the second load, respectively, to create an aerosol with flavor,

wherein the first load is an induction heating element,

wherein the first load and the second load are arranged at different positions which do not overlap each other in a longitudinal direction of the flavor generating device,

wherein the circuit comprises:

a first switch for opening/closing electric connection between the first load and the electric power source; and

a second switch for opening/closing electric connection between the second load and the electric power source,

wherein the controller is configured to:

open the second switch during generation of a plurality of electric power pulses by opening/closing of the first switch, and

open the first switch during generation of a plurality of electric power pulses by opening/closing of the second switch, and

wherein a current supplied from the electric power source to the second load by closing the second switch is larger than a current supplied from the electric power source to the first load by closing the first switch.

2. The flavor generating device according to claim 1 , wherein the controller is further configured to:

control the first switch or the second switch to open and close to modulate widths of the plurality of electric power pulses generated by opening/closing the first switch or the second switch.

3. The flavor generating device according to claim 1 , wherein the controller is further configured to:

control the circuit to include, before and after first periods in which the plurality of electric power pulses are generated by opening/closing the second switch, a second period in which the plurality of electric power pulses is generated by opening/closing the first switch.

4. The flavor generating device according to claim 3 , wherein the controller is further configured to control the circuit such that the second period includes a period which is longer than the first period.

5. The flavor generating device according to claim 1 , wherein the first load is positioned closer to a suction opening of the flavor generating device from which the aerosol with flavor is discharged than the second load.

6. The flavor generating device according to claim 1 , the flavor generating device further comprising a cylindrical body,

wherein the first load is positioned in a space around the cylindrical body.
