Referring to FIG. 1A, the stick 10 for an aerosol generating device according to an embodiment may include an inhaler 100, a storage 200, and a connector 300. The inhaler 100 may be a portion for the inhalation of a user, and the user may apply inhale pressure to the inhaler 100 to inhale an aerosol. The inhaler 100 may be formed as a mouthpiece such that the user may inhale easily. The storage 200 may store an aerosol forming substrate. A storage may desirably store the aerosol forming substrate of 0.03 ml to 0.06 ml. An end of the storage 200 may face and be connected to an end of the inhaler 100. The connector 300 may connect the storage 200 to an atomizer in the aerosol generating device as described below. The connector 300 may move the aerosol forming substrate stored in the storage 200 to the atomizer. The connector 300 may include porous materials, such as a cotton wick, a porous ceramic, a paper filter, or the like. The connector 300 may move the aerosol forming substrate in the storage 200 to the atomizer through a capillary phenomenon. The storage 200 may be between the inhaler 100 and the connector 300.
Referring to FIG. 1B, the stick 10 for an aerosol generating device according to an embodiment may include the inhaler 100, the storage 200, the connector 300, and a channel 400. The channel 400 may cross the inhaler 100, the storage 200, and the connector 300. The channel 400 may face all the inhaler 100, the storage 200, and the connector 300. The channel 400 may function as an airflow channel through which an aerosol that has atomized in the atomizer moves. The aerosol forming substrate may move through the connector 300 to the atomizer and may be atomized in an aerosol form in the atomizer. As the user inhales the inhaler 100, the atomized aerosol may move, in operation F, through the channel 400 and may be inhaled by the user. The channel 400 may face the side surfaces of the inhaler 100, the storage 200, and the connector 300. The shape and structure of the channel 400 are not limited to the shape and structure illustrated in FIG. 1.

Referring to FIG. 2, an aerosol generating device 1, according to an embodiment, may include the stick 10 for an aerosol generating device, a power 500, a housing 600, and an atomizer 700. The stick 10 for an aerosol generating device may be mounted to or removed from the aerosol generating device.

The atomizer 700 may atomize an aerosol forming substrate by using a surface acoustic wave. The atomizer 700 may receive the aerosol forming substrate from the storage 200.
The atomizer 700 may include a surface acoustic wave generating element 710 configured to generate a surface acoustic wave, a substrate element 720 to which the surface acoustic wave generated by the surface acoustic wave generating element 710 may be transmitted, and a chamber element 730 configured to prevent the deviation of an atomized aerosol.
The surface acoustic wave generating element 710 may generate a surface acoustic wave configured to atomize a liquid. The surface acoustic wave may be an acoustic wave transmitted along the surface of an elastic body substrate and may be generated from an electrical signal as a result of a piezoelectric effect. The surface acoustic wave generated by the surface acoustic wave generating element 710 may atomize a liquid aerosol forming substrate. The surface acoustic wave generated by the surface acoustic wave generating element 710 may be transmitted to the substrate element 720.
The surface acoustic wave generating element 710 may be designed to generate a surface acoustic wave only when the user inhales the aerosol generating device. For example, the inhaler 100 may include a respiratory sensor (not shown). The respiratory sensor mounted to the inhaler 100 may sense that the user inhales the aerosol generating device and may generate an electrical control signal such that a surface acoustic wave generating element may operate only when the user inhales the aerosol generating device in the atomizer 700.
The connector 300 of the stick 10 for an aerosol generating device may transmit the aerosol forming substrate stored in the storage 200 to the substrate element 720 of the atomizer 700. The aerosol forming substrate transmitted to the substrate element 720 may be atomized in an aerosol form after meeting a surface acoustic wave applied from the surface acoustic wave generating element 710. An aerosol generated by the aerosol forming substrate being atomized may be included by the chamber element 730.

The control element (not shown) may supply the aerosol forming substrate to the substrate element 720 at a preset speed. A rate of flow of the liquid aerosol forming substrate supplied to the substrate unit 720 may be controlled to control an atomization amount of an aerosol generated in the atomizer 700.
The channel 400 of the stick 10 for an aerosol generating device may communicate with the chamber element 730. As the user inhales the inhaler 100, an aerosol inside the chamber element 730 may be inhaled, in operation F, by the user along the channel 400. The user may inhale the aerosol generating device until all the aerosol forming substrate stored in the storage 200 is exhausted. When all the aerosol forming substrate stored in the storage 200 is exhausted, the user may remove the stick 10 for an aerosol generating device from the aerosol generating device 1.
The power 500 may supply power to another member of the aerosol generating device 1 or the atomizer 700 as needed.
The housing 600 may surround the atomizer 700, the power 500, and the stick 10 for an aerosol generating device to protect them against external shocks or other external disturbances and may form the appearance of the aerosol generating device 1. The housing 600 may include a mechanical structure for easily mounting or removing the stick 10 for an aerosol generating device.

However, embodiments are not limited thereto. The wireless communication unit 984 may use subscriber information (e.g., international mobile subscriber identity (IMSI)) to identify and authenticate the aerosol generating device 900 in a communication network.
The controller 910 may control the overall operation of the aerosol generating device 900. In an embodiment, the controller 910 may include at least one processor. The processor may be implemented as an array of a plurality of logic gates or may be implemented as a combination of a general-purpose microprocessor and a memory in which a program executable by the microprocessor is stored. In addition, it is to be understood by one of ordinary skill in the art to which the present disclosure pertains that it may be implemented in other types of hardware.
The controller 910 may control the temperature of the heater 950 by controlling the supply of power from the battery 940 to the heater 950. For example, the controller 910 may control the supply of power by controlling the switching of a switch element between the battery 940 and the heater 950. In another example, a direct heating circuit may control the supply of power to the heater 950 according to a control command from the controller 910.
The controller 910 may analyze a sensing result obtained by the sensing of the sensing unit 920 and control processes to be performed thereafter. For example, the controller 910 may control power to be supplied to the heater 950 to start or end an operation of the heater 950 based on the sensing result obtained by the sensing unit 920. In another example, the controller 910 may control an amount of power to be supplied to the heater 950 and a time for which the power is to be supplied, such that the heater 950 may be heated up to a predetermined temperature or maintained at a desired temperature, based on the sensing result obtained by the sensing unit 920.
The controller 910 may control the output unit 930 based on the sensing result obtained by the sensing unit 920. For example, when a number of puffs counted through the puff sensor 926 reaches a preset number, the controller 910 may inform the user that the aerosol generating device 900 is to be ended soon, through at least one of the display 932, the haptic portion 934, or the sound outputter 936.
According to an embodiment, the controller 910 may control a power supply time and/or a power supply amount for the heater 950 according to a state of the aerosol generating article sensed by the sensing unit 920. For example, when an aerosol generating article 15 is in an over-humidified state, the controller 910 may control the power supply time for an inductive coil to increase a preheating time, compared to a case where the aerosol generating article 15 is in a general state.
One embodiment may also be implemented in the form of a recording medium including instructions executable by a computer, such as a program module executable by the computer. A computer-readable medium may be any available medium that can be accessed by a computer and includes all of a volatile medium, a non-volatile medium, a removable medium, and a non-removable medium. In addition, the computer-readable medium may include both a computer storage medium and a communication medium.
