The present disclosure relates to aerosol delivery devices. The aerosol delivery devices may include a reservoir containing a liquid aerosol precursor composition and an atomizer including an electrical resistance heating element and a nonfibrous liquid transport element having a microtextured surface adapted for surface wicking of the liquid aerosol precursor composition across the microtextured surface, the microtextured surface of the liquid transport element being in fluid communication with the reservoir and in fluid communication with the electric resistance heating element.

Microtextured liquid transport element for aerosol delivery device

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.

Aerosol delivery device with a reservoir housing and a vaporizer assembly

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 a heating member that can be formed of a heating element conformed to a heater substrate configured as a truncated cone (or similar shape) having a first end of a first size and a second end of greater size. In some embodiments, the disclosure provides methods of forming an aerosol delivery device, which can include providing a shell, providing a heating member formed of a heating element conformed to a substrate, configuring the heating member as a truncated cone (or similar shape) having a first end of a first size and a second end of greater size, and inserting the heating member within the shell.

Heater for an aerosol delivery device and methods of formation thereof

The present disclosure relates to a microfluidic vaporizer, an aerosol delivery device that may include such vaporizer, and methods for forming an aerosol. A microfluidic vaporizer can comprise a substrate that defines: a reservoir configured to hold a liquid; a heater adapted to vaporize the liquid; and a capillary channel configured for movement of the liquid from the reservoir to the heater. An aerosol delivery device can comprise a shell and a microfluidic vaporizer. The microfluidic vaporizer and aerosol delivery device can be used for forming aerosols with precise and reproducible compositions.

Aerosol delivery device with microfluidic delivery component

The present disclosure relates to aerosol delivery devices. The aerosol delivery devices include mechanisms configured to deliver an aerosol precursor composition from a reservoir to an atomizer including a vaporization heating element to produce a vapor. For example, a bubble jet head may be configured to dispense the aerosol precursor composition to the atomizer. The bubble jet head may be fixedly coupled to the atomizer. The bubble jet head may include a precursor inlet, an ejection heating element, and a precursor nozzle. The atomizer may include a vaporization heating element.

Aerosol delivery device including a bubble jet head and related method

An aerosol delivery device includes a receptacle configured to receive a substrate configured to carry an aerosol precursor composition, and a resonant transformer including a transmitter coupling device and a resonant receiver coupling device that is positioned in proximity to the substrate when received in the receptacle. The aerosol delivery device also includes a pulse width modulation (PWM) inverter configured to drive the resonant transformer. The PWM inverter includes a bridge circuit coupled to the transmitter coupling device, and a PWM controller embodied as an integrated circuit and configured to output a PWM signal to the bridge circuit configured to drive the transmitter coupling device to generate an oscillating magnetic field and induce an alternating voltage in the resonant receiver coupling device when exposed to the oscillating magnetic field. The alternating voltage causes the resonant receiver coupling device to generate heat and thereby vaporize components of the aerosol precursor composition.

Induction-based aerosol delivery device

An aerosol delivery device is provided that includes a reservoir configured to retain aerosol precursor composition, a valve configured to control a flow of aerosol precursor composition from the reservoir to a heating element controllable to activate and vaporize components of the aerosol precursor composition, a sensor configured to measure reflectance or temperature at the heating element and generate a signal corresponding to the reflectance or temperature so measured, and a control component. The control component controls operation of the valve including receiving the signal and based thereon determining a volume of aerosol precursor composition at the heating element, and causing the valve to decrease or increase a rate of the flow of aerosol precursor composition in response to the volume being respectively above or below a predetermined threshold volume.

Fluidic control for an aerosol delivery device

The present disclosure provides an aerosol delivery device and a cartridge for an aerosol delivery device. In various implementations, the cartridge may comprise a housing defining a liquid reservoir, an atomizer configured to produce an aerosol, the atomizer comprising a first liquid transport element, a second liquid transport element, and a microvalve located between the liquid reservoir and the second liquid transport element. The microvalve may comprise a base member including at least one channel, and an actuating member at least a portion of which comprises a shape-memory material, and which is configured to move between a first position and a second position, wherein in the first position, the actuating member substantially blocks fluid flow from the liquid reservoir through the channel, and in the second position, the actuating member allows fluid flow from the liquid reservoir through the channel and to the second liquid transport element.

Shape memory material for controlled liquid delivery in an aerosol delivery device

The invention provides a smokeless tobacco composition adapted for oral use, the composition including a tobacco material and an effervescent material. The effervescent material includes a sugar material containing an entrapped gaseous component, such that release of the entrapped gaseous component occurs upon dissolution of the sugar material in the oral cavity. The invention also provides a method for making a smokeless tobacco composition that involves mixing a tobacco material with an effervescent material, the mixing step including either admixing a granulated composition comprising a tobacco material with a gasified sugar material in particulate form, or forming a gasified sugar material in situ by mixing a water source with a molten composition comprising a tobacco material and a sugar alcohol.

The present disclosure relates to aerosol delivery devices and related methods of delivering aerosol to a user. The aerosol delivery devices may include a housing providing multiple aerosol pathways having a mouth-end opening through which aerosol can be inhaled by a user, the housing defining a first aerosol delivery pathway in fluid communication with the mouth-end opening and a second aerosol delivery pathway separate from the first aerosol delivery pathway and in fluid communication with the mouth-end opening. An atomizer including a heating element or piezoelectric element and a liquid transport element in fluid communication with an aerosol precursor composition is provided in fluid communication with the first aerosol delivery pathway. A flavorant-infused material is positioned within the second aerosol delivery pathway and adapted to produce a second aerosol upon contact between the flavorant-infused material and flowing air.
