Description

Aerosol generating device {AEROSOL GENERATING APPARATUS}

The embodiment relates to an aerosol generating device, and in particular, to an aerosol generating device that prevents the liquid from being inhaled along with the aerosol by ensuring that the screen and the user's inhalation path are not in a straight line.

In general, an electronic cigarette refers to an electronic device made to inhale a solution containing nicotine filled in a replaceable cartridge into an aerosol or gaseous state (atomized state).

Such electronic cigarettes can satisfy the desire to smoke in place of regular cigarettes, and do not contain harmful ingredients such as tar, thereby reducing the harmful effects on the human body caused by cigarettes. At the same time, they do not cause the indirect damage of smoking. Due to its advantages, the number of users is increasing explosively. In other words, electronic cigarettes allow smoking indoors and have the same effect as smoking cigarettes while preventing the damage caused by cigarettes that cause various diseases.

In particular, in recent years, electronic cigarettes have been released that allow users to enjoy a variety of flavors by adding other flavors, such as fruit, to the taste of cigarettes.

In these electronic cigarettes, when an atomizer containing liquid nicotine is connected to the battery unit, the heating element of the atomizer generates heat and creates a haze that vaporizes the liquid nicotine.

However, the electronic cigarette of the prior art as described above consists of a wick that absorbs liquid nicotine as a heating element and a coil that heats the wick, so when used for a long time, the taste and aroma of the smoke change as the wick carbonizes, and the heat generation area is small. A problem occurs in which the amount of haze decreases.

The purpose of the embodiment is to provide an aerosol generating device that prevents the liquid from being inhaled along with the aerosol by ensuring that the screen and the user's inhalation path are not aligned in a straight line.

An aerosol-generating device according to an embodiment stores an aerosol-forming substrate, and includes a receiving space having an open lower side, a receiving portion having a first hollow penetrating in the vertical direction along the central axis of the receiving space, and a receiving portion having a diameter larger than the diameter of the first hollow. A porous ceramic hygroscopic body having a diameter and a second hollow penetrating in the vertical direction, which contacts the aerosol-forming substrate in the receiving part and transports it downward, and is mounted on the bottom of the porous ceramic hygroscopic body to transfer heat energy to the porous ceramic hygroscopic body. A heating part that transmits or diffuses the moisture to the porous ceramic moisture absorber and a receiving part, a fixing part that fixes the porous ceramic moisture absorber and prevents leakage, and a first cavity that communicates with the outside at the lower side of the bottom of the porous ceramic moisture absorber. It is provided with an airflow passage forming part, and a porous ceramic moisture absorber and a fixing part are located on the open lower side of the receiving space, at least a part of the first hollow is inserted into the second hollow, and between the bottom of the porous ceramic moisture absorbent and the first hollow. The fixing part is located at.

In addition, it is preferable that the lower end of the fixing part is located closer to the airflow passage forming part than the heating part and the bottom surface of the porous ceramic moisture absorber.

In addition, the receiving portion includes an outer case surrounding the outside of the receiving space, an inner case located inside the outer case and forming a hollow between the inner surface of the outer case along the central axis, and an outer case with the first hollow exposed to the external space. It consists of a cover part that covers the upper side of each of the inner cases and closes the upper side of the receiving space, and the fixing part is an inner side mounted between the inner side of the second hollow of the porous ceramic moisture absorber and the outer side and bottom side of the inner case of the receiving portion. It is preferably composed of a fixing part and an outer fixing part mounted between the outer surface of the porous ceramic moisture absorber and the inner surface of the outer case.

In addition, it is preferable that the lower end of the inner fixing part is located closer to the airflow passage forming part than the heating part and the bottom surface of the porous ceramic moisture absorber.

In addition, the fixing part does not cover at least a portion of the upper side of the porous ceramic hygroscopic body and does not cover at least a portion of the lower side of the porous ceramic hygroscopic body, and the heating part does not cover the lower side of the porous ceramic hygroscopic body that is not covered by the fixing part. It is desirable to be installed.

Additionally, the heating unit preferably includes at least one heating element including first and second terminals and a heating wire connected between the first and second terminals.

The embodiment has the effect of preventing the liquid from being inhaled along with the aerosol by ensuring that the screen and the user's inhalation path are not in a straight line.
