Technical Field

Background

In recent years, there has been an increasing demand for alternative methods for overcoming the disadvantages of ordinary cigarettes. For example, there is an increasing demand for methods of generating an aerosol not by burning a cigarette but by heating aerosol generating material within the cigarette. Therefore, studies on heated cigarettes and heated aerosol-generating devices are actively being conducted.

In aerosol-generating devices that heat cigarettes to generate an aerosol, a heater assembly that relies on electricity to generate heat is used. The heater module heats the cigarette in a state of being inserted into the cigarette, and in a process of repeatedly performing an operation of inserting and separating the cigarette, the coupling state between the components becomes loose, resulting in the heater shaking. Further, there are manufacturing tolerances between components coupled to the heater to support the heater, and the heater and the components may shake during cigarette mounting or separating operations because the position of the heater within the aerosol generating device cannot be stably maintained. As described above, when the assembled state of the heater assembly is poor, foreign substances from the outside are introduced into the interior of the aerosol-generating device through the heater assembly, thereby weakening the performance of the electronic components.
