Description

Shape-variable aerosol generating device {SHAPE-VARIABLE AEROSOL GENERATING DEVICE}

The embodiment relates to an aerosol generating device, and particularly to a shape-variable aerosol generating device whose external shape is variable around a first axis.

Aerosols are small liquid or solid particles that exist in suspension in the atmosphere and usually have a size of 0.001 to 1.0 ㎛. In particular, there are cases where people inhale aerosols derived from various types of cigarette-type aerosol-generating products.

An aerosol generating device is an electronic device that generates an aerosol by heating and steaming such a cigarette-type aerosol-generating article.

As the technology of aerosol generating devices develops, they are gradually becoming lighter, smaller, and slimmer. However, when the thickness is slimmed, the area becomes wider, or when it is miniaturized, the thickness becomes thick, causing discomfort when holding the aerosol generating device with the user's hand.

Additionally, the processor 290 obtains a charging direction input from the input unit 210 (e.g., charging from the charging device 300 to the power supply unit 230 or charging from the power supply unit 230 to the charging device 300, etc.). Therefore, the power supply unit 230 can be controlled according to the charging direction input to selectively charge the power supply unit 230 and charge the charging device 300. That is, when charging from the charging device 300 to the power supply unit 230, the power supply unit 230 stores the induced electromotive force applied wirelessly through the induction coil 260 in the built-in battery, or charges it from the power supply unit 230. When charging the device 300, the power supply unit 230 applies power from the built-in battery to the induction coil 260, so that the induction coil 360 of the charging device 300 receives the induced electromotive force, and the power supply unit 330 Charge the battery.
