Description

Heater assembly and aerosol generating device comprising same Technical Field Various embodiments of the present disclosure relate to a heater assembly and an aerosol-generating device including the same, and more particularly, to a heater assembly in which an oscillation portion and a resonance portion are coupled by screw coupling, and an aerosol-generating device including the same. Background In recent years, there has been an increasing demand for alternative methods of overcoming the shortcomings of conventional cigarettes. For example, there is an increasing demand for systems for generating aerosols by heating cigarettes or aerosol-generating substances using aerosol-generating devices, rather than burning the cigarettes. Thus, researches on heating type aerosol-generating devices are actively being conducted. On the other hand, in the method of heating an object, the microwave heating technique is a technique capable of directly heating polar molecules such as water or an organic solvent by using the principle of dielectric heating (DIELECTRIC HEATING). The material to be heated can be selectively heated by utilizing microwave heating, so that the microwave heating device has the advantages of high energy efficiency and high heating speed. Microwave heating technology, which is a novel heating method, is also continuously studied in the field of aerosol-generating devices. Disclosure of Invention Problems to be solved by the invention An aerosol-generating device for heating a cigarette (hereinafter, an "aerosol-generating article" may be used in the same sense as a cigarette) using a microwave heating technique generally includes an oscillating portion for generating microwaves and a resonating portion for heating the aerosol-generating article by resonating the microwaves. A slight error may occur in processing the resonance portion as the waveguide. In view of these manufacturing errors, a method of combining the resonance portion and the oscillation portion is particularly important in order to achieve the same performance for all the resonance portions. At this time, energy may be concentrated at a junction between the high-power oscillating portion and the resonance portion. Therefore, if the oscillating portion is bonded to the resonating portion by welding or the like, the high temperature may cause melting, thereby separating the bonding of the resonating portion to the oscillating portion. Accordingly, a solution is needed that enables easy and accurate adjustment of the connection of the oscillating portion to the resonating portion. Embodiments provide a heater assembly combining an oscillation part with a resonance part by screw bonding and an aerosol-generating device including the same. Furthermore, the embodiments provide a heater assembly and an aerosol-generating device including the same that can adjust a screw-thread coupling between an oscillating portion and a resonating portion even in a use phase other than a manufacturing phase. The problems to be solved by the embodiments are not limited to the above-described problems, and the problems not mentioned can be clearly understood by those skilled in the art from the present specification and drawings. Means for solving the problems The heater assembly may include an oscillating portion generating microwaves, an insertion space accommodating an aerosol-generating article, a resonating portion heating the aerosol-generating article through microwave resonance, and a microwave output portion transmitting the microwaves generated in the oscillating portion to the resonating portion. The microwave output part connected to the oscillation part may be screw-coupled to one region of the resonance part and couple the oscillation part to the resonance part. An aerosol-generating device according to an embodiment may comprise a heater assembly according to an embodiment, a housing for housing the heater assembly, a drive for moving the microwave output, and a processor electrically connected to the heater assembly. The processor may adjust the position of the microwave output part through the driving part so that the frequency of the microwaves generated in the oscillating part coincides with the frequency of the resonating part. Effects of the invention According to the heater assembly and the aerosol-generating device including the same of the embodiments, the same heating performance can be achieved even if there is a physical deviation of the resonance portion of each heater assembly. Furthermore, according to the heater assembly and the aerosol-generating device including the same of the embodiment, not only in the manufacturing stage, but also in the use stage, the user can easily adjust the heating performance. The effects of the embodiments are not limited to the above-described effects, and effects not mentioned can be clearly understood by those skilled in the art from the present specification and drawings.
