Abstract
Official abstract text for this publication.
Disclosed is an aerosol-generating device. The aerosol-generating device includes a heater configured to heat an aerosol-generating substance, a display, a power supply configured to supply power to the heater and the display, and a charging circuit configured to interconnect the power supply and the heater, and transmit power supplied from the power supply to the heater, wherein the display is connected to the power supply to receive power from the power supply.
First claim
Opening claim text (preview).
What is claimed is: 1 . An aerosol-generating device comprising: a heater configured to heat an aerosol-generating substance; a display; a power supply configured to supply power to the heater and the display; and a charging circuit configured to interconnect the power supply and the heater, and transmit power supplied from the power supply to the heater, wherein the display is connected to the power supply to receive power from the power supply. 2 . The aerosol-generating device according to claim 1 , wherein the display is connected to the power supply in parallel with the charging circuit, and receives power from the power supply not through the charging circuit. 3 . The aerosol-generating device according to claim 1 , wherein: the charging circuit has an input terminal connected to the power supply and an output terminal connected to the heater, and a voltage of the output terminal of the charging circuit is lower than an output voltage of the power supply. 4 . The aerosol-generating device according to claim 1 , further comprising a switch configured to interconnect the power supply and the display, and transmit power supplied from the power supply to the display. 5 . The aerosol-generating device according to claim 4 , wherein impedance between an output terminal and an input terminal of the switch is less than impedance between an output terminal and an input terminal of the charging circuit. 6 . The aerosol-generating device according to claim 4 , wherein a magnitude of a maximum allowable current of the switch is less than a magnitude of a maximum allowable current of the charging circuit. 7 . The aerosol-generating device according to claim 4 , further comprising a controller configured to control operations of the switch and the charging circuit, wherein the controller is configured to independently control the operations of the switch and the charging circuit. 8 . The aerosol-generating device according to claim 7 , wherein the controller is configured to: compare a voltage of an output terminal of the charging circuit with a first threshold, and control the charging circuit to interrupt power supplied to the heater, based on the voltage of the output terminal of the charging circuit being less than or equal to the first threshold. 9 . The aerosol-generating device according to claim 8 , wherein the first threshold is less than a preset driving voltage of the display. 10 . The aerosol-generating device according to claim 9 , wherein the preset driving voltage corresponds to a minimum driving voltage at which flickering does not occur in the display. 11 . The aerosol-generating device according to claim 4 , further comprising a first regulator configured to interconnect the power supply and the switch, and convert power supplied from the power supply. 12 . The aerosol-generating device according to claim 7 , further comprising a second regulator configured to interconnect the output terminal of the charging circuit and the controller, and convert power supplied from the power supply.
