A fluid delivery device and a method for controlling the delivering of a fluid to a user. The fluid delivery device includes a cartridge body; a fluid outlet nozzle attached to the cartridge body; a fluid jet ejection cartridge disposed in the cartridge body, the fluid jet ejection cartridge containing a fluid and an ejection head attached to the fluid jet ejection cartridge; wherein the ejection head contains a plurality of fluid ejectors thereon and a nozzle plate having a plurality of fluid ejection nozzles therein associated with the plurality of fluid ejectors configured to deliver the fluid to a user at a predetermined rate. A control system is disposed in the fluid delivery device that includes a differential pressure sensor for sensing an inhalation differential pressure. The control system is configured to terminate fluid delivery below a threshold inhalation differential pressure.

A vaporizing assembly for an aerosol-generating system may comprise a delivery device and a heater assembly. The heater assembly may comprise a heat resistive substrate and a heating element. The delivery device is configured to deliver an aerosol-forming substrate to at least a surface of the heat resistive substrate, wherein the heating element is isolated or separated from the aerosol-forming substrate by the heat resistive substrate. The present disclosure is also directed to a method for generating an aerosol.

A nebulizer for nebulizing a fluid is proposed. The nebulizer includes an indicator device with a rotatable indicator element for counting or indicating a number of actuations performed or still possible with the nebulizer and a rotatable shaft which rotatably drives the indicator element. The indicator device is non-detachably attached to the shaft and/or to an inner part of the nebulizer. The nebulizer may further include a positioning device that keeps the shaft in a defined rotational position and/or blocks the shaft from rotating backwards.

A mist inhaler device (200) for generating a mist for inhalation by a user. The device includes a mist generator device (201) and a driver device (202). The driver device (202) is configured to drive the mist generator device (201) at an optimum frequency to maximise the efficiency of mist generation by the mist generator device (201).

A vaporizing article, comprises a vaporizer drive circuit; one or more memories configured to store a percentage of at least one constituent in an inhalation media, one or more compensation values for at least one compensation category for the at least one constituent, and instructions; and a control circuit comprising a processor coupled with the one or more memories configured to run the instructions, the instructions configured to cause the processor to: receive a dose target for a constituent; determine whether to perform compensation for an inhalation media dose in order to ensure the dose target is met; when compensation is to be performed, determine the properly compensated inhalation media dose based on an associated compensation value for the constituent; and control the vaporizer drive circuit so as to dispense a compensated dose of the inhalation media.

A mist inhaler device (200) for generating a mist for inhalation by a user. The device includes a mist generator device (201) and a driver device (202). The driver device (202) is configured to drive the mist generator device (201) at an optimum frequency to maximise the efficiency of mist generation by the mist generator device (201).

A method of controlling a heater of a device including a removable container that stores a material includes detecting, from the removable container, power information indicating a first operating point and a second operating point; and supplying power to the heater based on the detected power information by, determining a first amount of power based on the first operating point, supplying the first amount of power to the heater during a first operation mode of the heater, determining a second amount of power based on the second operating point, and supplying the second amount of power to the heater during a second operation mode of the heater, the second amount of power being higher than the first amount of power, the device being a non-nicotine e-vaping device or a heat-not-burn aerosol-generating device, the material being a non-nicotine pre-vapor formulation or an aerosol-forming substrate.

A nebulizer for a fluid, includes a container containing the fluid; a housing part which can be detached from the nebulizer for replacing the container; an inner part; a retaining element connected with and not detachable from the inner part, where the housing part is releasable fixed to the inner part by the retaining element; a delivery mechanism for dispensing the fluid; a manually depressible actuator member, which is a separate part from the retaining element and acts on the retaining element, and wherein the actuator member is depressed to elastically deform or flex the retaining element to allow detachment of the housing part.

The present disclosure relates generally to the field of nicotine delivery. The disclosure teaches a nicotine meta-salicylate. More specifically, the disclosure teaches a condensation nicotine aerosol where nicotine meta-salicylate is vaporized. This disclosure relates to aerosol nicotine delivery devices. The delivery devices can be activated by actuation mechanisms to vaporize thin films comprising a nicotine meta-salicylate. More particularly, this disclosure relates to thin films of nicotine salt with meta salicylic acid for the treatment of nicotine craving and for effecting smoking cessation.

An inhaler (10) has a main body for accommodating a medicament reservoir (84), a canister fire system for moving a canister (50) to release a dose in response to air flow, a cap housing (12) for enclosing the canister fire system and canister within an interior chamber defined by the main body (14) and a cap housing, wherein a lock system (250) is provided for locking the cap housing on the main body.
