Technical Field

Embodiments of the present invention relate to a vaporizer and an aerosol-generating device including the vaporizer, and more particularly, to a vaporizer including a liquid leakage prevention structure and an aerosol-generating device including the vaporizer.

Background

In recent years, there has been an increasing demand for alternative methods to overcome the disadvantages of ordinary cigarettes. For example, there is an increasing demand for methods of generating aerosols by heating aerosol generating substances within a cigarette rather than by burning the cigarette. Therefore, studies on heated cigarettes and heated aerosol-generating devices are actively being conducted.

The aerosol-generating device may be provided with a vaporiser capable of generating an aerosol. The vaporizer has a liquid storage part, and the liquid composition in the liquid storage part is absorbed by the liquid transfer unit and heated by the heating part. The heating member heats the liquid composition and the external air to generate the aerosol. Therefore, the aerosol-generating device includes an airflow inlet through which outside air can flow into the vaporizer.

When the user uses the aerosol-generating device, the liquid composition flows from the liquid reservoir to the liquid delivery unit. When the liquid composition flows, the path along which the liquid composition flows needs to be tightly sealed.

If the path through which the liquid composition flows is not tightly sealed, leakage of the liquid composition to other structures inside the aerosol-generating device or to the outside of the aerosol-generating device may occur. The liquid composition flowing out is directed out of the vaporizer and may be directed towards the gas stream inlet of the aerosol-generating device.

When such leakage occurs repeatedly, the structure of the aerosol-generating device is contaminated, and the performance of the aerosol-generating device may be deteriorated, or the aerosol-generating device may become inoperable. In addition, when the liquid composition flows out to the air flow inlet of the aerosol-generating device, the liquid composition flowing out may give an unpleasant feeling to the user of the aerosol-generating device.
