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.

The elastic portion includes a base, a vertical protrusion that is spaced at a certain distance from the edge of the base on the upper surface of the base, protrudes and extends upward to form an upper space, and surrounds the side of the vertical protrusion and protrudes and extends in the outward direction to form an upper space. An aerosol generating device comprising a vertical extension and a horizontal protrusion supporting the horizontal extension. According to claim 6,
An electrical contact portion connected to a heating wire is provided on the lower side of the heater base,
An aerosol generating device, wherein the coupling terminal penetrates the support portion and the elastic portion and contacts the electrical contact portion. According to claim 4,
An aerosol generating device, characterized in that the inner surface of the case is provided with an inner protrusion protruding toward the center. According to claim 8,
A coupling groove is formed on the horizontal protrusion of the heater unit,
A connecting protrusion is formed on the lower side of the inner protrusion,
By combining the engaging groove and the engaging protrusion, the central axis of the horizontal airflow through hole of the case and the central axis of the first through hole of the heater unit are located in the same vertical plane,
An aerosol generating device, wherein the central axis of the vertical airflow through hole of the case and the central axis of the second through hole of the heater unit are located at the same vertical plane. According to claim 6,
As the upper side of the case and the upper cover unit are combined, the heater unit and the elastic portion are compressed, but the contact force or contact area between the porous moisture absorber cartridge and the heater unit increases due to the tensile force of the horizontal protrusion, or the contact force or contact area between the heater unit and the coupling terminal increases.
