The article includes a refillable liquid retention section and an aerosol-generation section located within a casing. The refillable liquid retention section includes a liquid retention medium, and the aerosol-generation section is located downstream of the refillable liquid retention section. The liquid retention medium has a capacity to absorb up to 35 microliters of liquid. The article is configured such that, during use, air can be drawn through the article from the distal end to the end, passing through the refillable liquid retention section. The article defines an opening or port for allowing the refillable liquid retention section to be charged with liquid.

An electrically conductive flat filament arrangement for a fluid permeable heater assembly for aerosol-generating systems includes a center portion and two side portions. The two side portions are on opposite sides of the center portion. The center portion defines a heating region of the filament arrangement and the side portions define electrical contact regions of the filament arrangement. The center portion and the two side portions each include a plurality of openings. Each plurality of openings defines an open area of the center portion and an open area of each of the two side portions. A percentage of the total area of the center portion including the open area of the center portion is greater than the percentage of the total area of one of the side portions including the open area of the side portion.

A flavored vapor generator (100, 200, 300, 400) used for an electronic smoking apparatus (10) comprises a housing; a liquid retention material (155, 255) which is filled, soaked or immersed with a flavored liquid and received inside the housing; an electric heater (150, 350, 450) for heating the liquid retention material (155, 255) to generate flavored vapor; and a sensor (156, 356, 456) for monitoring soaking or wetness conditions of the liquid retention material (155, 255) and providing signals for determining whether the flavored liquid in the liquid retention material (155, 255) is exhausted or almost exhausted.

A reservoir component of an electronic vaping device includes an outer housing, an air inlet, a vapor outlet, an air passage communicating with the air inlet and the vapor outlet, and a reservoir. A magnetic, electrically conductive and resistive heater element is located adjacent the air passage. The heater element is configured to be in electrical communication with an alternator of a power supply component. A wick is in communication with the reservoir and is configured to draw pre-vapor formulation from the reservoir toward the heater element. The heater element is configured to heat pre-vapor formulation to a temperature sufficient to vaporize the pre-vapor formulation and form a vapor.

The present disclosure provides an aerosol delivery device and a cartridge for an aerosol delivery device. In various implementations, the aerosol delivery device comprises a control device that includes an outer housing defining a cartridge receiving chamber, and further includes a power source and a control component, and a cartridge that includes a mouthpiece, a tank, a heating assembly, and a bottom cap. The mouthpiece defines an exit portal in an end thereof, and the tank is configured to contain a liquid composition therein. The cartridge is configured to be removably coupled with the receiving chamber of the control device, and the heating assembly defines a vaporization chamber and is configured to heat the liquid composition to generate an aerosol. An inlet airflow is defined by a gap between the cartridge and the control device that originates at an interface between an outer peripheral surface the mouthpiece and control device.

Disclosed herein are methods and systems to vaporize extract, plant material containing organic material and the like utilizing convection heating via one or more manifolds each in fluid communication with a section of chamber containing organic material. The manifolds may be valved and may contain temperature sensors.

A low-temperature smoking set, comprising a housing assembly (1) and a heating assembly (4) disposed in the housing assembly (1), wherein a cavity (121) used for inserting a cigarette (10) is provided on the housing assembly (1), and a cigarette accommodating cavity (P1) used for accommodating at least a part of the cigarette (10) is provided at the inner part of the housing assembly (1). At least one cigarette holding mechanism (5) is disposed at the cavity wall of the cigarette accommodating cavity (P1). The cigarette holding mechanism (5) comprises at least two deformable elastic protrusion parts (P2) arranged at intervals along the circumference of the cigarette accommodating cavity (P1). The elastic protrusion parts (P2) are in the shape of sheets and extend from the cavity wall of the cigarette accommodating cavity (P1) toward the inner part of the cigarette accommodating cavity (P1) along the radial direction of the cigarette accommodating cavity (P1), thereby implementing adaptive adjustment according to the diameter of the cigarette (10) so as to adapt to cigarettes of different diameters (10). In addition, since the elastic protrusion parts (P2) are in the shape of sheets, heat dissipation may be better prevented, thereby ensuring the baking efficiency of the cigarette (10).

A heater for aerosol generation devices and an aerosol generation device including the same are provided. The heater according to some embodiments of the present disclosure may include a first electroconductive pattern which is configured to perform a heating function and a second electroconductive pattern which is made of a material with a temperature coefficient of resistance higher than that of the first electroconductive pattern and is configured to perform a temperature measurement function for the heater. In this case, since a temperature of a heating surface of the heater may be accurately measured through the second electroconductive pattern, control precision for the heater may be improved.

A heat exchanger for fluids includes an elongated conduit. At least two spaced fluid passageways are defined in the conduit and extend longitudinally through the conduit from a first end thereof to a second end thereof. A heat transfer element thermally contacts a surface of the conduit to transfer heat to or from a fluid flowing through the at least two spaced passageways. The conduit can be unitary and of one piece. In one embodiment, the conduit can be a single crystal.

An exhaust gas heater system for an exhaust system of an internal combustion engine includes a housing and a heating element. The housing includes an outer peripheral wall disposed about a central axis and defining an interior hollow space configured to receive exhaust gas from an exhaust pipe of the exhaust system such that the exhaust gas flows through the interior hollow space. The heating element is positioned within the hollow space and including a first end and a second end. The heating element forms a zig-zag shape extending in a radial direction relative to the central axis.
