The present disclosure relates to a cleaning device and an aerosol-generating, and an aerosol-generating system including the same. Since the cleaning device according to an embodiment may receive electrical energy wirelessly from the aerosol-generating device, the cleaning device may operate without an internal battery or a wired power connection. Therefore, a weight of the cleaning device and its manufacturing cost may be reduced, and a user does not need to charge the cleaning device regularly.

Provided are an aerosol generating device (100), a charging base (200), and an electric system. The aerosol generating device (100) comprises: a first part (10), comprising a chamber (11) configured for receiving a smokable material, and a heating element (30); the first part (10) also comprising a gap (12), through which the heating element (30) can be cleaned; in the direction of the cross section of the first part (10), connecting lines from the center of the heating element (30) to two ends of the gap (12) forming an included angle less than 90 degrees; a second part (12) removably connected to the first part (10), which is arranged to close or open the gap (12) by means of configuration between connected to the first part (10) or removed from the first part (10). The first part (10) of the aerosol generating device (100) is provided with a gap (12).

The susceptor includes: a metal body, being penetrable by a changing magnetic field to generate heat; a protective layer formed on the metal body, the protective layer having a surface micro-nano structure with a lotus effect so that the adhesion or deposition of organic substances from a smokable material on the surface of the susceptor is reduced. The solid substances such as tobacco slags and dust may hard to break through the micro-nano structure and directly infiltrate into the surface and the smallest diameter of aerosol condensate oil and water vapor or the like is larger than the micro-nano structure, so that spherical bodies which are easy to roll down are formed by the aerosol condensate oil and water vapor under the action of their own surface tension, thereby preventing the adhesion or deposition of organic substances on the surface.

Provided is a smoking member cleaning device formed to clean a smoking member, the smoking member cleaning device including a main body unit; an accommodating unit formed in one region of the main body unit to accommodate one region of the smoking member when the smoking member is being cleaned; a cleaning unit formed in the accommodating unit and configured to clean the smoking member; a cleaning driving unit connected to the cleaning unit and configured to clean the smoking member by moving the cleaning unit; and a power supply unit configured to supply driving energy to the cleaning driving unit.

A vaporizer (20) is shaped to define a flow channel (120) that is open to an environment external to the vaporizer at first and second ends of the flow channel. At the first end of the flow channel is a mouthpiece (112) of the vaporizer. A flow sensor (114) includes (a) a nanoscale resistive element (200) disposed at least partially within the flow channel and (b) sensing circuitry (115) configured to measure a change in the nanoscale resistive element due to airflow within the flow channel. Other applications are also described.

A refill bottle and system for an electronic cigarette. The refill bottle and system can comprise a refill bottle. The refill bottle can comprise a bottle housing, a bottle cavity defined by the bottle housing, and a refill assembly coupled to the bottle housing. The refill assembly can comprise a bottle stopper, a movable assembly, a spring, a filling projection, and a projection opening. The refill assembly can be configured to cover the filling projection and the projection opening when no force is acting upon the refill assembly. The refill system can further comprise an eCig tank comprising a tank side wall, a tank reservoir defined by the tank side wall, and a self-sealing port coupled to the tank side wall.
