Abstract: An aerosol generating device includes a heating chamber; and a thermoelectric cell. The aerosol generating device is configured to supply electrical power to the thermoelectrical cell and the thermoelectric cell is arranged such that, when electrical power is supplied to the thermoelectric cell, heat is transferred through the thermoelectrical cell to the heating chamber by the thermoelectrical cell. A control unit is configured to control the heat transferred by the thermoelectrical cell so as to regulate an internal temperature of the heating chamber. A method of controlling the aerosol generating device includes controlling the heat transferred through the thermoelectric cell so as to regulate the internal temperature of the heating chamber.

Abstract: An aerosol generating device includes a vibrator configured to vibrate to generate an aerosol from an aerosol generating material, a controller configured to control the vibrator to vibrate at a target vibration speed, and a feedback circuit configured to detect an electrical signal representing a frequency response of the vibrator that changes according to an operating environment of the vibrator and output a feedback signal based on the detected electrical signal, and the controller may adjust the vibration speed of the vibrator based on the feedback signal output from the feedback circuit.

Abstract: The invention relates to an aerosol-generating device. The aerosol-generating device comprises a first housing portion and a second housing portion. The first housing portion comprises a cavity for receiving an aerosol-generating article comprising aerosol-forming substrate. The first housing portion and second housing portion are configured arrangeable in a first position, in which the first housing portion is extended relative to the second housing position, and in which the cavity is accessible for insertion of the aerosol-generating article. The first housing portion and second housing portion are configured arrangeable in a second position, in which the second housing portion is retracted at least partly within the cavity.

Abstract: The invention relates to an aerosol-generating device comprising a mainbody (10) and a mouthpiece (12). The main body comprises a heating chamber (14) for receiving an aerosol-forming substrate. The mouthpiece is movably connected to the main body. The mouthpiece is configured movable with respect to the main body in a first movement between a first position and a second position. The first position is an operation position of the aero sol-generating device. In the second position, the heating chamber is at least partially exposed. The mouthpiece is configured movable with respect to the main body in a second movement between the second position and a third position. The second movement of the mouthpiece from the second position to the third position is configured to trigger an event.

Abstract: The invention relates to an aerosol-generating device (10) comprising a top portion (20), a main portion (70), and a cartridge (50). The top portion comprises a proximal end comprising a cavity (22) for receiving an aerosol-generating article (12). The top portion further comprises a distal end comprising a top cartridge connector (24) and a top airflow channel extending from the top cartridge connector to the cavity. The main portion comprises a proximal end comprising a main cartridge connector (72). The main portion furthers comprises a main air inlet and a main airflow channel extending from the main air inlet to the main cartridge connector. The top cartridge connector is removably attachable to a proximal end of the cartridge and the main cartridge connector is removably attachable to a distal end of the cartridge enabling a first mode of operation. The top cartridge connector is directly removably attachable to the main cartridge connector enabling a second mode of operation.

Abstract: An aerosol-generating device is provided, including: a cavity configured to receive an aerosol-generating article including aerosol-forming substrate; a first air inlet fluidly connected with the cavity and configured to enable ambient air to be drawn into the cavity; a second air inlet fluidly connected with the cavity and configured to enable ambient air to be drawn into the cavity; and airflow controller for controlling one or both of airflow through the first air inlet and the second air inlet.

Abstract: A filter component for tobacco smoking, comprises a filter body (1), a filter core material (2), and a filter closing layer (3). The filter body (1) is a hollow cylinder, and the filter core material (2) is built in the filter body (1). At least one end of the filter body (1) is closed by the filter closing layer (3). The filter core material (2) is a granular filter material, filament filter material, folded filter material, or similar filter material having a shape structure with a large specific surface area. The filter component for smoking can be widely used in the field of tobacco and can be built into cigarettes or arranged in related accessories. The filter component for smoking can effectively filter moisture and tar in smoke, and can also ensure good smoking feel and effect.

Abstract: An inhalation device cartridge includes a liquid storage portion configured to store liquid, an atomizing portion configured to atomize the liquid, and a flexible liquid transporting member configured to transport the liquid stored in the liquid storage portion toward the atomizing portion. The atomizing portion is a heating element having an elongated shape which includes electrical contact points at both ends and is pressed into a main surface of the liquid transporting member. The pressing depth at a center portion of the heating element is greater than the pressing depth at each end portion of the heating element.
