The invention relates to an inhaler, particularly an electronic cigarette product, comprising at least one evaporator device having at least one electrical evaporator for evaporating liquid supplied to the evaporator and an electronic control device for controlling and/or regulating the evaporator. A plurality of liquids are associated or can be associated with the evaporator device in such a way that the composition and/or the vapour production rate of the vapour/aerosol produced by the at least one evaporator can be adjusted and/or modified in a targeted manner, as the control device is designed for individual control of the at least one or each individual evaporator and/or for group control of the evaporators.

An evaporator unit for an inhaler, in particular for an electronic cigarette product, comprises an electrically operable, in particular planar, heating body which has an inlet side and an outlet side, and a plurality of microchannels which each extend from the inlet side to the outlet side through the heating body, the heating body being designed to evaporate, by applying a heating voltage, liquid transferred through the microchannels. A porous and/or capillary wick structure is arranged on the inlet side of the heating body, which structure rests flat against and in contact with the heating body and covers all of the microchannels on the inlet side.

The invention relates to a liquid store for an inhaler (10), in particular for an electronic cigarette product, having an outlet end (53) which can be fluidically connected to a heating element (60) in order to evaporate liquid (50) supplied to the heating element (60) from the liquid store (18). The liquid store (18) has at least one air inlet end (52) and at least one channel (51). The channel (51) extends from the air inlet end (52) to the outlet end (53) through the liquid store (18), wherein the channel (51) is designed to transfer the liquid (50) stored in the liquid store (18) to the outlet end (53) through the channel (51) by means of capillary forces.

The invention relates to an evaporator unit for an inhaler, in particular an electronic cigarette product, comprising an electrically operable heating body, in particular a flat heating body, which has an inlet side and an outlet side, and a plurality of microchannels, each of which extends from the inlet side to the outlet side through the heating body. The heating body is designed to evaporate liquid being transferred through the microchannels by applying a heating voltage. A porous and/or capillary wick structure is arranged on the inlet side of the heating body, said wick structure being fluidically connected or connectable to a liquid store. The wick structure has a shaft which extends through a through a passage opening of the support, and a collar, which is arranged between the support and the heating body, wherein the diameter of the collar is greater than the diameter of the passage opening of the support.

A microfluidic dispensing device has a plurality of chambers arranged in sequence, each having an inlet receiving a liquid to be dispensed and a nozzle for emitting a drop of liquid. An actuator in each chamber receives an actuation quantity and causes a drop of liquid to be emitted by the nozzle of the respective chamber. A drop emission detection element in each chamber generates an actuation command upon detecting the emission of a drop of liquid. A sequential activation electric circuit includes a plurality of sequential activation elements, one for each chamber, each coupled to the drop emission detection element of the respective chamber and to an actuator associated with a subsequent chamber in the sequence of chambers. Each sequential activation element receives the actuation command from the drop emission detection element associated with the respective chamber and activates the actuator associated with the subsequent chamber in the sequence of chambers.

A method of delivering safe, suitable, and repeatable dosages to a subject for topical, oral, nasal, or pulmonary use and a device for droplet ejection includes a fluid delivery system capable of delivering a defined volume of the fluid in the form of droplets having properties that afford adequate and repeatable high percentage deposition upon application. The method and device include a housing, a reservoir disposed within the housing for receiving a volume of fluid, an ejector mechanism configured to eject a stream of droplets having an average ejected droplet diameter greater than 15 microns, the stream of droplets having low entrained airflow such that the stream of droplets deposit on the eye of the subject during use.

A delivery device for and a method of delivering gases to the nasal airway, in particular therapeutic gases and gases in combination with active substances, either as powders or liquids, for enhanced uptake of the active substances.

An indirectly heated capillary aerosol generator comprises a capillary tube adapted to form an aerosol when liquid material in the capillary tube is heated to volatilize at least some of the liquid material therein and a thermally conductive material in thermal contact with the capillary tube. The indirectly heated capillary aerosol generator provides substantially even and uniform heating across the heated length of the capillary tube.

A component for a vapour provision system comprises a reservoir for storing aerosolisable substrate material, the reservoir bounded by a boundary wall with at least one movable section configured to move to reduce a storage volume of the reservoir; an outlet in the reservoir for dispensing aerosolisable substrate material from the reservoir; a one-way outlet valve at the outlet configured to open for the dispensing of the aerosolisable substrate material; and a dispensing arrangement operable to increase pressure of aerosolisable substrate material in an outlet volume of the reservoir which is not bounded by the movable section, so as to open the outlet valve and dispense a portion of aerosolisable substrate material, the subsequent absence of the dispensed portion reducing the pressure to allow the movable section of the boundary wall to move to reduce the storage volume.
