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.

A device for inhaling powder-type substances includes a plurality of substance containers that can be moved successively into an emptying position, wherein the substance containers—which are not connected to one another—are accommodated in direct contact with one another in a guide unit attached to the device and can be moved by contact pressure propagating among the substance containers. The guide unit has a drive wheel with accommodating forms separated by drive teeth. The substance container in the emptying position is located in an accommodating form of the drive wheel. A substance container for a device for inhaling powder-type substances has two sub-regions, each separately having an amount of the substance, and both sub-regions have an openable, pierceable cover. A method for filling a device for inhaling powder-type substances uses a plurality of substance containers that can be moved successively into an emptying position.

A device for inhaling powder-type substances includes a mouthpiece, an insertion unit having a retaining part with an insertion means for opening a sub-region in a substance container containing the substance, and a discharge channel for the substance leading to the mouthpiece. In order to advantageously further improve a device of this type, it is proposed that two insertion units are provided, having preferably two retaining parts, which are separate from one another, which each have an insertion means, and with which the substance container can be opened in intersecting or opposing insertion directions. The device for inhaling powder-type substances also includes a plurality of substance containers that can be moved successively into an emptying position. The number of emptied or non-emptied substance containers can be displayed via a counter.

A mobile inhaler is configured to provide an inhalable aerosol to a user. The mobile inhaler may include a vibrating mesh atomizer. The vibrating mesh atomizer may include a vibrating mesh membrane comprising a plurality of holes, a piezoelectric actuator coupled to the vibrating mesh membrane, wherein the processing equipment is configured to actuate the piezoelectric actuator, and a vibrating mesh membrane holder. The mobile inhaler includes processing equipment, which may include memory configured to store information about one or more users, including usage behaviour. A capsule is used to hold liquid for atomizing and may include a plunger to dispense liquid. The processing equipment may be configured to determine desired dosages, or other desired usage metrics, based on the stored information. In some embodiments, information from a plurality of mobile inhalers may be stored and analysed.

A nicotine powder inhaler (10) comprises a body extending between a mouthpiece portion (12) and a distal end portion (14), an airflow channel (15) extending between the mouthpiece portion and the distal end portion and a nicotine powder receptacle (20) disposed along the airflow channel, and a powder system disposed within the nicotine powder receptacle. The powder system includes a first plurality of particles having a particle size of about (10) micrometres or less and including nicotine and a second plurality of particles having a particle size of about 20 micrometres of greater and including flavour. The first plurality of particles comprise an amino acid or nicotine selected from the group consisting of nicotine pyruvate, nicotine mono-pyruvate, nicotine aspartate and nicotine lactate.
