The cover is covered on the shell and the water storage tank, the cover is provided with a spray port communicated with the mist channel and an water inlet communicated with the water storage tank, the mist and the volatilizing essential oil float through the mist channel and the spray port to humidify air.

A method of treating respiratory system tissue, includes operations of generating a plume of particles of a treating solution from a nebulizer, inhaling particles of the treating solution, delaying exhalation of an inhalation having particles of the treating solution therein, and determining whether a dose of the treating solution has been delivered, wherein the treating solution is a solution of at least 40% ethyl alcohol, by volume.

A charger for an electronic nicotine delivery systems (“ENDS”) device, which may include aerosol delivery devices provides functionality for authentication, including age verification. Such devices may be restricted based on age or other factors that require some form of authentication, verification, and/or identification to satisfy the restriction. The accessory or charger may provide or connect with a verification system for confirming an age of a user. If the authentication or verification is not satisfied, the charger or accessory will not charge the device, rendering it unusable.

An in-line droplet delivery device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The in-line droplet delivery device includes a housing, a mouthpiece, a reservoir, an ejector mechanism, and at least one differential pressure sensor. The in-line droplet delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The in-line droplet delivery device is then actuated to generate a plume of droplets having an average ejected particle diameter within the respirable size range, e.g, less than about 5-6 μm, so as to target the pulmonary system of the user. the droplet delivery device is configured in an in-line orientation in that the housing, its internal components, and various device components (e.g., the mouthpiece, air inlet flow element, etc.) are orientated in a substantially in-line or parallel configuration (e.g., along the airflow path) so as to form a small, hand-held device.

The present disclosure relates to a device for nebulizing a liquid composition and to methods for disinfecting an internal channel of the nebulizer device. The device includes a channel connecting a liquid composition inlet, a mesh and a liquid composition outlet. The mesh divides the channel into an input channel portion and into an output channel portion. The channel is at least partially optically transparent to bacterial disinfecting electromagnetic radiation. The device includes a first emitter configured to illuminate the input portion of the channel with the bacterial disinfecting electromagnetic radiation and a second emitter configured to illuminate the output portion of the channel with the bacterial disinfecting electromagnetic radiation.

A flavored vapor generator (100, 200, 300, 400) used for an electronic smoking apparatus (10) comprises a housing; a liquid retention material (155, 255) which is filled, soaked or immersed with a flavored liquid and received inside the housing; an electric heater (150, 350, 450) for heating the liquid retention material (155, 255) to generate flavored vapor; and a sensor (156, 356, 456) for monitoring soaking or wetness conditions of the liquid retention material (155, 255) and providing signals for determining whether the flavored liquid in the liquid retention material (155, 255) is exhausted or almost exhausted.

The present disclosure provides an aerosol delivery device and a liquid delivery and atomization assembly for use with an aerosol delivery device. In one implementation, the liquid delivery and atomization assembly comprises a liquid composition, an atomization assembly, and a liquid delivery component configured to transport at least a portion of the liquid composition to the atomization assembly. The liquid delivery component comprises at least one microchannel configured to deliver the portion of the liquid composition to the atomization assembly, and the microchannel includes a variable flow characteristic defined along at least a portion of the microchannel, the variable flow characteristic being configured to control the flow of the portion of liquid composition through the microchannel.

A portable nebulizer provided by the invention is particularly suitable for using with a liquid contained in a capsule or in a container made of a disposable material that can be easily damaged, the portable nebulizer comprises a driving unit for driving an atomizing unit, and a containing unit for containing the container, the containing unit has a breaking part for breaking the container to facilitate outflow of the liquid, after the liquid flows into an inner space of a main body of the containing unit because the container is damaged by the breaking part, the liquid can be atomized by the atomizing unit to produce a mist capable of escaping to the outside of the main body for a user to use the liquid mist conveniently.

The nebulizer gas scavenging system includes a condenser positioned in the expiratory pathway of the breathing circuit for extracting liquid from expiratory gases and redirecting the extracting liquid to the input of the nebulizer. The system is further configured to detect the actual consumption of inhaled medication by measuring the concentration of medication in the expiratory pathway and comparing it to the initial content of medication in the aerosol of the inspiratory pathway. A more accurate determination of the amount of inhaled medication is advantageous in certain critical situations involving application of medication by inhalation.
