Definitions
- the present disclosure relates to an aerosol-generating article and an aerosol-generating device.
- tobacco refers to a perennial herbaceous plant belonging to the Solanaceae, a family of dicotyledonous plants, and recently, also collectively refers to a product manufactured for the purpose of smoking and consisting of tobacco leaves in cigarette paper and a filter at one side.
- tobacco products There are thousands of tobacco products in the worldwide market, and they come in a variety of shapes and forms.
- tobacco smoke contains many components such as tar, nitroamines, hydrocarbons, and carbon monoxide, in addition to aerosols containing nicotine.
- an aerosol-generating device has a form similar to that of a conventional combustible tobacco product, and generates mainstream smoke including aerosols by heating an aerosol-generating material in a heating-type cigarette through a means such as a heater or ultrasonic vibration.
- the aerosol-generating device has the advantage of minimizing emission of components such as tar while functioning to provide smokers with smoking satisfaction, and thus is attracting attention as a new market for replacing conventional combustible tobacco products.
- the heating-type cigarette heated by the aerosol-generating device generates high-temperature mainstream smoke therein, and this high-temperature aerosol may be delivered directly to a user.
- the high-temperature mainstream smoke may cause discomfort or burns to the user.
- the heating-type cigarette is not heated uniformly, the aerosol may not flow efficiently inside the cigarette.
- an objective of the present disclosure is to provide an aerosol-generating article capable of preventing a user from feeling discomfort or getting burned.
- Another objective of the present disclosure is to provide an aerosol-generating article capable of uniformly heating a tobacco medium portion to thereby improve generation of an abundant aerosol.
- an aerosol-generating article including a tobacco medium portion, a filter portion disposed to be spaced apart from the tobacco medium portion, a cooling portion disposed between the tobacco medium portion and the filter portion, and a heat transfer portion surrounding at least a portion of the cooling portion.
- an aerosol-generating article can prevent a user from feeling discomfort or getting burned by high-temperature mainstream smoke.
- FIG. 1 is a schematic exploded perspective view illustrating an aerosol-generating article according to a first embodiment of the present disclosure.

In addition, the heat transfer portion 190 may further cool the aerosol moving inside the cooling portion 130. A detailed process thereof will be described later.
- FIG. 5 is a view illustrating a process in which the tobacco medium portion is heated by inserting the heater into the aerosol-generating article according to an embodiment of the present disclosure.
- FIG. 6 is a view illustrating a process in which a tobacco medium portion is heated by inserting the heater into an aerosol-generating article according to the related art.
- the heat transfer portion 190 may insulate the aerosol while the tobacco medium portion 110 is heated before the user inhales the mainstream smoke, and may cool the aerosol while the user inhales the mainstream smoke.
- the process in which the user inhales the mainstream smoke using the aerosol-generating article 100 may include a process in which the tobacco medium portion 110 is initially heated by the heater 370 of the aerosol-generating device 300 (see FIG. 22) which is inserted into the tobacco medium portion 110 to generates an aerosol, and a process in which the user inhales the mainstream smoke through the mouth when the tobacco medium portion 110 reaches a predetermined temperature for generating the aerosol.
- the heat transfer portion 190 may insulate the downstream side P of the tobacco medium portion 110 adjacent to the cooling portion 130. Thereby, while the tobacco medium portion 110 is heated, the heat transfer portion 190 may insulate the downstream side of the tobacco medium portion 110 such that the entire section of the tobacco medium portion 110 is heated to a uniform temperature.
- the heat transfer portion 190 may be made in the form of a metal foil, so that heat generated by the heater 370 at the downstream side P of the tobacco medium portion 110 may be prevented from being dissipated to the outside through a body of the cooling portion 130.

- FIG. 6 illustrates a process in which the aerosol-generating article 100 according to the related art is heated by the heater 370. While the heater 370 initially heats a tobacco medium portion 110, heat at a downstream side P of the tobacco medium portion 110 is dissipated to the outside through an adjacent cooling portion 130 (see FIG. 6(A)). Thereby, the temperature of the downstream side P of the tobacco medium portion 110 is lower than that of a remaining section M of the tobacco medium portion 110 (see FIG. 6(B)).
- the heater 370 may have a shape in which an electrical resistive heater H is surrounded by a ceramic material C, and there is a possibility that the cooling portion 130 is melted by the high-temperature heater 370. Therefore, the insertion length of the heater 370 is limited so that an end thereof is not close to the cooling portion 130. In other words, the heater 370 is inserted so that the end thereof does not reach an end of the tobacco medium portion 110. Accordingly, since the heater 370 is inserted so that the end thereof does not reach the end of the tobacco medium portion 110, the downstream side P of the tobacco medium portion 110 may not be provided with as much heat as the remaining section M. In addition, as the heat at the downstream side P is dissipated and released to the outside through the adjacent cooling portion 130, the temperature of the downstream side P of the tobacco medium portion 110 may be lower than that of the remaining section M.
- the heat transfer portion 190 insulates the downstream side of the tobacco medium portion 110 while the tobacco medium portion 110 is heated. This enables the aerosol generated in the tobacco medium portion 110 to efficiently flow toward the cooling portion 130 without being stagnant at the downstream side of the tobacco medium portion 110 due to lower temperature.
- the heat transfer portion 190 may further cool the high-temperature aerosol moving inside the cooling portion 130.
