Description

Power unit of an aerosol generating device The present invention relates to a power unit of an aerosol generating device. Patent documents 1 and 2 describe a power unit of an aerosol generating device equipped with a voltage conversion IC that steps up and/or steps down power. In the power unit of these aerosol generating devices, in order to improve the aerosol generation efficiency, the power voltage is converted by the voltage conversion IC and then supplied to a heater. To enhance the functionality of these aerosol generating devices, the number of circuit boards or the variety of power supply voltages on the circuit boards in the power unit increases. Thus, for example, Patent Document 3 describes a power unit of an aerosol generating device having a first circuit board having a charging terminal and a resistor formed thereon, and a second circuit board having a charging IC, an MCU, and a switch formed thereon.

Hereinafter, a suction system, which is an embodiment of an aerosol generating device according to the present invention, will be described with reference to the drawings. This suction system comprises a non-combustion type suction device (100) (hereinafter referred to simply as "suction device (100)"), which is an embodiment of a power unit of the present invention, and a rod (500) heated by the suction device (100). In the following description, a configuration in which the suction device (100) indetachably accommodates a heating unit is described as an example. However, the heating unit may be configured to be detachable from the suction device (100). For example, the rod (500) and the heating unit may be integrated and configured to be detachable from the suction device (100). That is, the power unit of the aerosol generating device may not be configured to include a heating unit as a component. Furthermore, "indetachable" refers to a configuration in which separation cannot be performed only for the intended use. Alternatively, an induction heating coil installed in the suction device (100) and a susceptor embedded in the rod (500) may cooperate to form a heating unit. FIG. 1 is a perspective view showing the overall configuration of the suction device (100). FIG. 2 is a perspective view of the suction device (100) showing the state with the rod (500) mounted.
