The effects of an aerosol generating device and an aerosol generating system according to an embodiment are not limited to the above-mentioned effects, and other unmentioned effects may be clearly understood from the following description by one of ordinary skill in the art.
The terms used to describe the embodiments are selected from among common terms that are currently widely used, in consideration of their function in the disclosure. However, different terms may be used depending on an intention of one of ordinary skill in the art, a precedent, or the advent of new technology. Also, in particular cases, the terms are discretionally selected by the applicant of the disclosure, and the meaning of those terms will be described in detail in the corresponding part of the detailed description. Therefore, the terms used in the disclosure should be defined based on the meanings of the terms and all the content of the disclosure, rather than the terms themselves.
It will be understood that when a certain part “includes” a certain component, the part does not exclude another component but may further include another component, unless the context clearly dictates otherwise. Also, terms such as “unit,” “module,” etc., as used in the specification may refer to a part for processing at least one function or operation and which may be implemented as hardware, software, or a combination of hardware and software.
As used herein, an expression such as “at least one of” that precedes listed components modifies not each of the listed components but all the listed components. For example, the expression “at least one of a, b, or c” should be construed as including a, b, c, a and b, a and c, b and c, or a, b, and c.
In an embodiment, an aerosol generating device may be a device that generates an aerosol by electrically heating an aerosol generating article accommodated in an inner space.
The aerosol generating device may include a heater. In an embodiment, the heater may be an electrically resistive heater. For example, the heater may include an electrically conductive track, and the heater may be heated as a current flows through the electrically conductive track.
The heater may include a tubular heating element, a plate-shaped heating element, a needle-shaped heating element, or a rod-shaped heating element, and may heat the inside or outside of the aerosol generating article according to the shape of a heating element.

In another embodiment, the aerosol generating device may be a device that generates an aerosol using a cartridge containing an aerosol generating material.
The aerosol generating device may include a cartridge containing the aerosol generating material and a main body supporting the cartridge. The cartridge may be detachably coupled to the main body. However, embodiments are not limited thereto. The cartridge may be integrally formed or assembled with the main body, and may be secured to the main body so as not to be detached by a user. The cartridge may be mounted on the main body while the aerosol generating material is accommodated therein. However, embodiments are not limited thereto. The aerosol generating material may be injected into the cartridge while the cartridge is coupled to the main body.
The cartridge may hold the aerosol generating material in any one of various states, such as a liquid state, a solid state, a gaseous state, and a gel state. The aerosol generating material may include a liquid composition. For example, the liquid composition may be a liquid including a tobacco-containing material having a volatile tobacco flavor ingredient, or a liquid including a non-tobacco material.
The cartridge may be operated by an electrical signal or a wireless signal transmitted from the main body to perform the function of generating an aerosol by converting the phase of the aerosol generating material inside the cartridge to a gaseous phase. The term “aerosol” may refer to a gas in which vaporized particles generated from the aerosol generating material are mixed with air.
In another embodiment, the aerosol generating device may generate an aerosol by heating the liquid composition, and the generated aerosol may pass through the aerosol generating article and be delivered to the user. That is, the aerosol generated from the liquid composition may travel along airflow paths of the aerosol generating device, and the airflow paths may be configured to allow the aerosol to pass through the aerosol generating article and be delivered to the user.
In another embodiment, the aerosol generating device may be a device that generates an aerosol from the aerosol generating material using an ultrasonic vibration technique. In this case, the ultrasonic vibration technique may be a technique of generating an aerosol by atomizing the aerosol generating material with ultrasonic vibration generated by a vibrator.
The aerosol generating device may include a vibrator, and may generate vibration at short intervals through the vibrator to atomize the aerosol generating material. The vibration generated by the vibrator may be ultrasonic vibration, and a frequency band of the ultrasonic vibration may be from about 100 kilohertz (kHz) to about 3.5 megahertz (MHz). However, embodiments are not limited thereto.
The aerosol generating device may further include a wick that absorbs the aerosol generating material. For example, the wick may be disposed to surround at least one area of the vibrator or may be disposed to contact at least one area of the vibrator.
As a voltage (e.g., an alternating voltage) is applied to the vibrator, the vibrator may generate heat and/or ultrasonic vibration, and the heat and/or ultrasonic vibration generated by the vibrator may be transmitted to the aerosol generating material absorbed in the wick. The aerosol generating material absorbed in the wick may be converted into a gas phase by the heat and/or ultrasonic vibration transmitted from the vibrator, and consequently, an aerosol may be generated.
For example, viscosity of the aerosol generating material absorbed in the wick may be lowered by the heat generated by the vibrator, and the aerosol generating material with lowered viscosity may be changed to fine particles by the ultrasonic vibration generated by the vibrator, and thereby an aerosol may be generated. However, embodiments are not limited thereto.
In another embodiment, the aerosol generating device may be a device that generates an aerosol by heating the aerosol generating article accommodated therein in an induction heating manner.
The aerosol generating device may include a susceptor and a coil. In an embodiment, the coil may apply a magnetic field to the susceptor. As the aerosol generating device supplies power to the coil, a magnetic field may be formed inside the coil. In an embodiment, the susceptor may be a magnetic body that generates heat by an external magnetic field. As the susceptor is positioned inside the coil and generates heat with the magnetic field applied, the aerosol generating article may be heated. Also, optionally, the susceptor may be positioned in the aerosol generating article.
In another embodiment, the aerosol generating device may further include a cradle.
The aerosol generating device and the separate cradle may form a system together. For example, the cradle may be used to charge a battery of the aerosol generating device. Alternatively, a heater may be heated when the cradle and the aerosol generating device are coupled to each other.
