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.

Provided is an anion electronic cigarette that includes an atomizer (1) and battery assembly (2) which are electrically connected to each other. The anionic electronic cigarette further includes an anion generation device, comprising an anion generator (14) which is electrically connected to the control circuit provided in the battery assembly (2). The anion electronic cigarette causes electronic smoke comprised of high-density anions to enter the human body, which can help smokers to mitigate the smoking addiction and even quit smoking, while providing a cleaner a method of smoking. At the same time, when it is required to add liquid tobacco tar into the electronic cigarette in the present invention, it only requires opening the cigarette nozzle and pulling out the sealing pillar from the tar injection hole to inject tobacco tar into the tobacco tar cavity, which is fast and convenient and is not easy for tar to leak.

The present disclosure relates to aerosol delivery devices. The aerosol delivery devices include mechanisms configured to deliver an aerosol precursor composition from a reservoir to an atomizer including a vaporization heating element to produce a vapor. For example, a bubble jet head may be configured to dispense the aerosol precursor composition to the atomizer. The bubble jet head may be fixedly coupled to the atomizer. The bubble jet head may include a precursor inlet, an ejection heating element, and a precursor nozzle. The atomizer may include a vaporization heating element.

A pharmaceutical drug delivery device and method of using the pharmaceutical drug delivery device. The pharmaceutical drug delivery device includes a cartridge body; a fluid outlet nozzle attached to the cartridge body; and a fluid jet ejection cartridge disposed in the cartridge body, wherein the cartridge contains a liquid pharmaceutical drug and a fluid ejection head containing a plurality of fluid ejection nozzles and associated fluid ejectors. A processor disposed on a logic board or fluid ejection head is provided for executing a control algorithm to control the ejection head to modify plume characteristics of fluid ejected from the ejection head by controlling one or more of fluid jet firing frequency, burst length, and fluid jet firing burst delay.

A pharmaceutical drug delivery device and method of preventing drying out and drooling of an ejection head for the drug delivery device. The device includes a drug delivery device body; a fluid outlet nozzle attached to the drug delivery device body; and a fluid jet ejection cartridge containing a liquid pharmaceutical drug disposed in the drug delivery device body. A fluid ejection head is attached to the fluid jet ejection cartridge and the fluid ejection head is in fluid flow communication with the fluid outlet nozzle. An elongate, serpentine air flow path is provided between and outer surface of the fluid jet ejection cartridge and an inner surface of the fluid outlet nozzle. The elongate, serpentine air flow path provides a reduced pressure differential adjacent to a surface of the fluid ejection head upon use of the drug delivery device and provides a humidification zone.

An ejector device for ejecting droplets of fluid onto a surface includes an ejector mechanism attached to a fluid reservoir through a fluid loading plate that is configured to pierce the reservoir and channel the fluid to a rear surface of the ejector mechanism by capillary action. The ejector mechanism may have a centro-symmetric configuration with a lead free piezo actuator and may be covered by an auto-closing cover.
