摘要： An aerosol delivery device is provided that comprises a housing equipped with a heating element, a resistance temperature detector (RTD) and a control component. The housing may contain an aerosol precursor composition, and the heating element may be controllable to activate and vaporize components of the aerosol precursor composition. The RTD may have a resistance that is variable and proportional to a temperature of the heating element, and may also have a temperature coefficient of resistance that is suitably large enough and invariable with respect to the temperature of the heating element. The control component may be configured to measure the resistance of the RTD and therefrom determine the temperature of the heating element, and control at least one functional element in real time based on the temperature so determined, including output of the temperature for presentation by a display, or adjustment of the power to the heating element.

摘要： The present disclosure relates to an aerosol delivery device that includes a reservoir housing that defines a mouthpiece channel. The aerosol delivery device includes a sealing member configured to be received within the reservoir housing to define a reservoir chamber configured to retain an aerosol precursor composition therein. The aerosol delivery device also includes a substrate member that is configured to be received within the reservoir housing and to be directly engaged with a vaporizing assembly for forming an aerosol. The reservoir housing, sealing member, substrate member, and/or vaporizing assembly can be used for forming aerosols with precise and reproducible compositions.

摘要： The present disclosure relates to an aerosol production assembly. The aerosol production assembly may include a reservoir that contains an aerosol precursor composition and an atomizer that receives the aerosol precursor composition from the reservoir and heats the aerosol precursor composition to produce an aerosol. The aerosol production assembly may additionally include a body that directs the aerosol through an outlet. The body may include a surface including a micro-pattern that defines at least one of hydrophobic and anti-microbial properties. The surface including the micro-pattern may not include a chemical coating that provides these properties. Rather, the surface may define a three-dimensional structure that provides hydrophobic and/or anti-microbial properties. A related assembly method is also provided.

摘要： An aerosol delivery device having a detachable power source is provided. A control body may be coupleable with a cartridge to form an aerosol delivery device. The cartridge may contain an aerosol precursor composition and be equipped with a heating element configured to activate and vaporize components of the aerosol precursor composition. The control body may comprise a housing and a power source detachably coupled to an outer surface of the housing. A control component may be contained within the housing and configured to operate in an active mode in which the control body is coupled with the cartridge. The control component in the active mode may be configured to direct power from the power source to the heating element to activate and vaporize components of the aerosol precursor composition.

摘要： The present disclosure relates to an aerosol delivery device configured to wirelessly heat an atomizer. The aerosol delivery device may include a control body and a cartridge. The control body may include an induction transmitter. The cartridge may include an induction receiver and an aerosol precursor composition. When electrical current is directed to the induction transmitter, the induction receiver may be inductively heated. The heat produced by the induction receiver may form an aerosol from the aerosol precursor composition at the substrate. Related methods are also provided.

摘要： The present disclosure is directed to an aerosol delivery device. The aerosol delivery device may include one or more fill ports. Thereby, a reservoir of the aerosol delivery device may be refillable. The fill ports may be defined in a base of a cartridge of the aerosol delivery device. The aerosol delivery device may further include a flow director. An atomizer may extend through the flow director transversely to a longitudinal length of the flow director. The atomizer may include a liquid transport element with a capillary channel extending therethrough, which may receive aerosol precursor composition from the reservoir. There aerosol precursor composition may be drawn through the liquid transport element to a heating element of the atomizer, which may vaporize the aerosol precursor composition.

摘要： The present disclosure relates to aerosol delivery devices, methods of forming such devices, and elements of such devices. For example, some aerosol delivery devices of the current disclosure include a reservoir having a liquid aerosol precursor composition, an electrical heater in fluid communication with the reservoir and configured to vaporize the liquid aerosol precursor composition to form an aerosol, and a filter operatively arranged relative to the electrical heater such that at least a portion of the formed aerosol passes therethrough, the filter being configured to selectively bind one or more undesirable impurities.

摘要： The present disclosure relates to aerosol delivery devices, methods of forming such devices, and elements of such devices. In some embodiments, the present disclosure provides devices configured for vaporization of an aerosol precursor composition that is stored in and/or transported to a heater by a porous monolith, which can be, for example, a porous glass or a porous ceramic. A heater can be in a heating arrangement with an external portion of the porous monolith or can be substantially internal to the porous monolith.

摘要： The present disclosure provides components useful in heating, particularly heating of an aerosol precursor solution so as to vaporize the solution and form an aerosol. The disclosure particularly provides an electrically conductive, porous carbon heater. The heater may be combined with an aerosol precursor transport element that also is formed of carbon. The heater and transport element may form an atomizer that can be useful in an electronic smoking article, such as in a cartridge that is adapted for attachment to a control body. In some embodiments, the disclosure provides a cartridge of an electronic smoking article, the cartridge being formed substantially completely of carbon.
