The invention relates to a replaceable flavor cartridge for an aerosol-generating device. The cartridge comprises a housing and a flavor substrate. The flavor substrate is arranged within the housing. The housing comprises a proximal aperture in a proximal end face of the housing. The housing comprises a distal aperture in a distal end face of the housing. The flavor substrate comprises a substrate aperture. The proximal aperture, the distal aperture and the substrate aperture are aligned with each other to form a cartridge airflow channel through the cartridge. The invention further relates to an aerosol-generating device.

Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include a reservoir configured to contain a plurality of encapsulated particles and an airflow tube extending through the reservoir. Each of the plurality of encapsulated particles includes a core formed of a liquid vaporizable material and a coating material that forms a shell surrounding the core, in which the shells of the plurality of encapsulated particles are configured to be selectively ruptured to release the liquid vaporizable material therefrom. The airflow tube includes a wicking element that is in communication with the reservoir, in which the wicking element is configured to draw, into the airflow tube for vaporization, at least a portion of the liquid vaporizable material that is released by rupturing one or more shells of the plurality of encapsulated particles. Vaporizer devices are also provided.

An aerosol-generating system (includes a cartridge, a liquid aerosol-forming substrate, and an aerosol-generating device. The cartridge includes a cartridge housing and a solid aerosol-forming substrate. The aerosol-generating device includes a cavity configured to receive at least a portion of the cartridge, an airflow inlet, and an airflow sensor. The airflow sensor is in fluid communication with the airflow inlet and the cavity). The aerosol-generating device includes a bypass air inlet in fluid communication with the cavity, an electric heater configured to heat the liquid aerosol-forming substrate, a power supply, and a controller. The aerosol-generating system is configured so that the cartridge housing substantially prevents airflow through the bypass air inlet when the cartridge is received within the cavity.

A portable, personal storage and carrying case for an e-liquid e-cigarette PV in which the case includes: a refillable PV that is removable from the case; an electrical power source for re-charging a rechargeable battery in the PV; a user-replaceable reservoir for holding e-liquid; and an electrical or electronic pump adapted to transfer e-liquid from the reservoir to a chamber in the PV, the pump delivering a pre-defined or variable quantity of e-liquid from the reservoir; and in which the case has closed and open positions, and lifts up the removable PV when in the open position to enable a user to readily withdraw the PV from the case.

This flavor inhaler is provided with a housing having an air flow path that spans continuously from an inlet to an outlet, and an atomizing part for atomizing an aerosol source without accompanying combustion of the aerosol source, wherein at least one portion of the air flow path is an aerosol flow path which is a flow path for an aerosol generated from the atomizing part, and the air blow resistance of the whole air flow path is not greater than 25 mmAq.

An aerosol-generating system may include a liquid storage portion configured to hold aerosol-forming substrate, a vaporizer, and a pump. The liquid storage portion includes a movable wall and an outlet. The vaporizer includes a heating element having a structure that at least partially defines an internal passage. The pump may deliver liquid aerosol-forming substrate from the outlet of the liquid storage portion to the internal passage of the heating element. The pump may include a micro stepper motor with a drive shaft that is configured to rotate a particular amount based on performing an individual step, a piston connected to the movable wall, and a lead screw connecting the drive shaft to the piston and configured to translate rotation of the drive shaft into axial movement of the piston and the movable wall. The vaporizer may at least partially vaporize the delivered liquid aerosol-forming substrate.
