Description

Aerosol generating device Technical Field Various embodiments of the present invention relate to an aerosol-generating device that can sense the over-wet and over-dry condition of a cigarette by a humidity-sensitive resistor sensor. Background In recent years, there has been an increasing demand for alternative methods to overcome the disadvantages of conventional cigarettes. For example, there is an increasing demand for methods of generating aerosols by heating aerosol-generating substances, rather than by burning cigarettes. Accordingly, research into a heated aerosol-generating device is actively underway. When the aerosol-generating article is inserted into the receiving space, the aerosol-generating device may heat the aerosol-generating article according to a preset temperature profile. The temperature profile may refer to temperature change data of a heater or aerosol-generating article during a smoking action. The aerosol generated as the aerosol-generating article is heated may vary depending on the composition of the aerosol-generating substance contained in the aerosol-generating article. For example, depending on the moisture content contained in the aerosol-generating substance, there may be a difference in the temperature, yield, etc. of the aerosol produced. Disclosure of Invention Problems to be solved by the invention When the aerosol-generating article comprises a quantity of moisture, by preheating the aerosol-generating article, an aerosol of suitable temperature and yield can be generated. However, when the water content contained in the aerosol-generating article at the time of warm-up exceeds an appropriate range, the water content causes a decrease in the temperature rising speed of the heater, so that excessive water vapor may be generated and high-temperature aerosol may be generated. In addition, when the water content in the aerosol-generating article is below the proper range upon preheating, it may be difficult to generate a sufficient amount of aerosol. Accordingly, there is a need for an aerosol-generating device that can set different pre-heating temperature profiles depending on the moisture content of the aerosol-generating article. However, the problems solved by the embodiments of the present invention are not limited to the above-described problems, and the problems not mentioned can be clearly understood from the present specification and drawings by those of ordinary skill in the art to which the embodiments of the present invention belong. Means for solving the problems An aerosol-generating device of an embodiment may include a housing including a receptacle into which an aerosol-generating article is inserted, a heater disposed on one side of the membrane to heat the aerosol-generating article when powered, a humidity sensor disposed on one side of the membrane to sense humidity of the aerosol-generating article, and a processor electrically connected to the heater and the humidity sensor, the processor controlling power to the heater based on the humidity of the aerosol-generating article sensed by the humidity sensor. Effects of the invention According to various embodiments of the present invention, the aerosol-generating device may provide the humidity sensor on the film provided with the heater, thereby enabling sensing of the humidity of the aerosol-generating article inserted in the container portion even without adding a separate structure for providing the humidity sensor. However, effects based on the embodiments are not limited to the above-described effects, and effects not mentioned can be clearly understood by those of ordinary skill in the art to which the embodiments of the present invention belong from the present specification and drawings.
