Description

FIELD

The present disclosure relates to the field of atomization devices, and in particular, to an aerosol generation device and a driving mechanism.

BACKGROUND

An aerosol generation device, as an emerging technology, has replaced a traditional-burning cigarette by heating e-liquid or a low temperature cigarette. The aerosol generation device works at a low heating temperature, and produces far less harmful ingredients than the traditional-burning cigarette when heating. Therefore, the aerosol generation device can greatly avoid adverse effects from the cigarette to the human body and thus provides a healthier way of smoking. Currently, there are two typical aerosol generation devices in the market. The first one is an electronic atomization device that generates inhalable aerosol by evaporating the e-liquid. The second one is a low-temperature heating device that generates inhalable aerosol by heating the tobacco at a low temperature in a non-burning state. Generally, as for the low-temperature heating device, a heater such as a heating sheet is inserted into the cigarette to heat the cigarette. By controlling the heating temperature, the components of the cigarette are volatilized into the aerosol. When a cigarette is heated to a certain time, the amount of the aerosol produced by the cigarette reaches a maximum, and it is necessary to pull the cigarette out of the device to stop smoking or to replace a new cigarette to continue smoking. How to easily and quickly pull the cigarette out from the device without damaging the cigarette and without leaving residues on the heater becomes a crucial problem. Currently, the cigarette is taken out of the device manually by pulling the cigarette. However, due to that the pulling strengths and directions of users are different, problems, such as the cigarette is broken apart, or there are some residues attached to the heater, tend to be caused when pulling the cigarette by users.
