An aerosol generating device includes a first heater for heating a liquid composition accommodated in a liquid storage of a vaporizer, a puff sensor detecting a pressure change within the aerosol generating device, and a controller. The aerosol generating device may determine a puff pattern including a plurality of sections, based on a signal received from the puff sensor. In addition, the aerosol generating device may control an operation of the first heater, based on states of the plurality of sections.

A ceramic heater according to one aspect of the present invention has a cylindrical ceramic heater and an annular metal flange fitted around the ceramic heater. In the ceramic heater, one side of the flange with respect to an axial direction of the heater body is concave in the axial direction to define a concave part. The concave part includes a glass accumulation region filled with a glass material. The glass material in the glass accumulation is fused to the flange and to the heater body.

A vaporization device comprises one or more batteries disposed in a body portion having a first longitudinal center plane and two or more identical substance cartridges each adapted to detachably attach to the body portion in first and second orientations relative to the first longitudinal center plane.

A thermal immersion circulator can comprise a heater including a hollow cylindrical main body having an inlet opening at a first end thereof and an outlet opening in a side wall thereof. The heater can include a flexible circuit board having a plurality of resistive bands controlled by controlling electronics such as TRIACs, which can be water-cooled. A thermal immersion circulator including such a heater can be used in scientific laboratories or sous vide food cooking.
