A sensing module for monitoring dosage delivery of a vaporized material, and a portable vaporization unit including the sensing module, include a light sensor that detects disruptions in a light path across a vapor channel, the disruptions caused by the vaporized material flowing through the vapor channel. The light sensor includes a UV light source, which may emit 370 nm wavelength light, and a UV light detector that converts intensity of incident light in the light path into a signal. A microprocessor of the sensing module compares the signal to a baseline measurement to determine the concentration of a medicament in the vapor; then, using the flow rate and activation time of the device, the microprocessor determines the dosage and can perform monitoring and reporting actions based on the dosage. A measuring circuit measures fluctuations in resistance/impedance of a vaporization element to further determine flow rate and/or dosage.

An aerosol-generating article for providing an electrical stimulation to a user is provided, including an aerosol-forming substrate; first and second electrodes; and first and second tipping papers, the first electrode being disposed at a first position of the substrate to provide a first electrical contact to the user, the second electrode being disposed at a second position at a front face of the substrate to provide a second electrical contact to the user, the second position being different from the first position to provide an electrical potential between the first and the second electrodes and to provide an electrical stimulation to the user, the first electrode being accessible for a first region of the mouth that is a first area on a tongue of the user, and the second electrode being accessible for a second region of the mouth of the user that is different from the first region.

An identification component for an aerosol-generating device is provided, the identification component including: a ring shaped body; a customizable surface; and connector for reversibly connecting the identification component to the aerosol-generating device, in which the identification component is a ring-shaped component that is configured to be mounted at an open end of a heating chamber of the aerosol-generating device. An aerosol-generating device including a reversibly connectable identification component is also provided. A system including the aerosol-generating device and a removal tool is also provided.

The present disclosure describes an aerosol delivery component comprising a tank defining a storage chamber for storing a first liquid aerosol precursor and an air bleed channel extending from an outside channel opening outside of the tank to an inside channel opening within the tank. The air bleed channel has a volume between 1% and 20%, e.g. greater than 10% of the volume of the storage chamber. The air bleed channel may comprise an s-bend channel for retaining the first liquid aerosol precursor in an inverted orientation of the component.

A vaporizer is disclosed. The vaporizer includes a liquid storage housing having a liquid storage cavity formed therein and a base arranged at one end of the liquid storage housing. The base includes an air inlet protruding stage that has an upper surface facing the liquid storage cavity. The upper surface is in a shape of a protrusion. The air inlet protruding stage is provided with a plurality of air inlet holes extending from the upper surface away from the liquid storage cavity.

A vaporization core applied to an electronic vaporization device includes: a porous substrate having a liquid guide part that has a liquid absorbing surface for absorbing a liquid substrate and a vaporization surface on which a heating element is disposed, the liquid guide part conducting the liquid substrate on a side of the liquid absorbing surface to the vaporization surface; the heating element; and a vent part connected to the liquid guide part, the vent part having a hydrophobic ventilation characteristic, the vent part having an air inlet surface and an air outlet surface, the air inlet surface being for contacting gas, the air outlet surface being exposed to a liquid storage cavity, and the vent part being for conducting gas on a side of the air inlet surface to the air outlet surface.

A chip for a vaporizer includes: a package having a communication interface for determining whether a battery rod into which the vaporizer is inserted communicates with the vaporizer. When the battery rod communicates with the vaporizer, the vaporizer operates in a first mode. When the battery rod does not communicate with the vaporizer, the vaporizer operates in a second mode.

A flavor aspirator includes: a weight-concentrated part that is provided at a position off the mouthpiece end and closer to the mouthpiece end side than to a midpoint position between the mouthpiece end and the distal end, and that accounts for at least approximately half of a total weight of the flavor aspirator. A value of (a length from the mouthpiece end to the center of gravity)/(a total length defined by a length from the mouthpiece end to the distal end) is in a range of 0.20 to 0.45.
