An aerosol generating device includes a main body including a main body portion having an accommodation space into which an aerosol-generating article is inserted; a cap detachably coupled to the main body; a cartridge detachably coupled to the main body portion; a first sensor configured to detect whether the cap is attached or detached; a second sensor configured to detect whether the cartridge is attached or detached; a third sensor configured to detect a remaining amount of liquid in the cartridge; and a microcontroller electrically connected to the first sensor, the second sensor, and the third sensor. The microcontroller wakes up when a measurement value detected by the first sensor changes to a preset value or more and determines whether the cap is attached or detached, when it is determined that the cap has been removed from the main body, the microcontroller detects whether the cartridge is detached or not using the second sensor during a preset grace time, but when the microcontroller does not detect attachment or detachment of the cartridge during the grace time, the microcontroller switches to sleep mode when the grace time elapses, and during the sleep mode, the microcontroller wakes up when the measurement value detected by the third sensor changes to a preset value or more, and re-detects whether the cartridge is attached or detached using the second sensor.

An aerosol generating device includes a battery, a DC/DC converter configured to boost a voltage of the battery to supply a boosted voltage to a first heater and a second heater, a first resistor circuit connected in series with the second heater and configured to detect a current flowing through the second heater, a second resistor circuit connected in series with the first resistor circuit and configured to reduce a peak value of the current flowing through the second heater, an operation switch configured to determine whether or not the current flows through the second heater, and a processor configured to control the battery, the DC/DC converter, and the operation switch.

This aerosol generating device comprises: a chamber configured to hold an aerosol generating material; a heater configured to heat the aerosol generating material, the heater including a substrate which includes a first end portion, a second end portion opposite to the first end portion, and a side portion extending between the first end portion and the second end portion, and a plurality of metal particles disposed on the inner surface and configured to generate heat by surface plasmon resonance, wherein the substrate includes an outer surface at least partially facing the chamber and an inner surface opposite to the outer surface; and a wick configured to deliver the aerosol generating material from the chamber to the heater.

The aerosol-generating device may comprise: a cavity configured to accommodate an aerosol-generating article; and a heater configured to heat the aerosol-generating article, wherein the heater comprises: a plasma discharge space; a partition configured to separate the cavity and the plasma discharge space; and a plurality of plasma electrodes disposed in the partition.

An inhaler according to one embodiment comprises: a mouthpiece including a capsule containing functional materials; a housing having one end opened so that the mouthpiece is inserted therein; a piercing unit which is disposed inside the housing and which extends from the other end of the housing toward one end thereof; a sliding unit to which the mouthpiece is coupled and which slides inside the housing; and a stopper mounted on one side of the housing so as to limit the movement distance of the sliding unit, wherein an air inflow space can be ensured between the mouthpiece and the sliding unit.

An aerosol-generating device is disclosed. The aerosol-generating device includes a body including an insertion space to allow a stick to be inserted into the insertion space and a heater disposed in the body and including a heat generating portion configured to heat the insertion space. The heat generating portion includes a heat generating layer surrounding the insertion space and a wiring layer stacked on the heat generating layer and configured to supply a current. The heat generating portion has a thickness varying in the depth direction of the insertion space.

This wearable device providing a smoking effect comprises: a housing; a first stimulation unit provided on one surface of the housing and including at least one electrode disposed at a position corresponding to a first part of a user to provide electrical stimulation; a second stimulation unit provided on one surface of the housing and including at least one electrode disposed at a position corresponding to a second part of the user to provide electrical stimulation; and a controller for controlling the first stimulation unit or the second stimulation unit, wherein the first stimulation unit or the second stimulation unit can provide an electrical stimulation signal for inducing a state of arousal in which a smoking effect can be generated.
