A humidifier includes a container for containing a fluid; a cartridge for nebulizing the fluid, the cartridge configured to be fixed inside the container, the cartridge including a cartridge housing including a bottom side that is configured to contact a bottom of the container, a top side opposite to the bottom side; a back side; a front side; a left side; and a right side; and a handle on the top side of the cartridge housing, the handle projecting upward and away from the cartridge housing.

A mesh for use in a mesh nebuliser. The mesh 300 comprises a first plurality of apertures 310 extending through the mesh 300, the first plurality of apertures 310 having a first average diameter and a second plurality of apertures 320 extending through the mesh 300, the second plurality of apertures 320 having a second average diameter. The first average diameter is different to the second average diameter. The first average diameter may be sized to produce droplet of 1-5 μm, whereas the second average diameter may be sized to produce droplets of 5-30 μm. There is also provided a mesh nebuliser having the present mesh.

A material applicator for controlling application of at least one material on a substrate includes a housing and an array plate with an applicator array positioned within the housing. The applicator array has a plurality of micro-applicators and each of the plurality of micro-applicators has an ultrasonic transducer, a material inlet, a reservoir, and a micro-applicator plate with a plurality of apertures. The applicator plate is in mechanical communication with the ultrasonic transducer such that at least one material is ejected through the plurality of apertures as atomized droplets when the ultrasonic transducer vibrates the micro-applicator plate.

A fluid dispensing apparatus and liquid container with a fluid dispensing apparatus are provided. The fluid dispensing apparatus includes a valve body defining a bore that extends at least partially through a valve body, and an adaptor including a piercing member positioned to pierce a pierceable membrane enclosing the liquid container. The adaptor also includes a releasable fastener that cooperates with a portion of the liquid container to releasably couple the valve body to the liquid container. A liquid droplet production apparatus of the fluid dispensing apparatus controls a discharge of the liquid from the liquid container. The liquid droplet production apparatus includes a perforate membrane, and an actuator that is selectively operable to vibrate the perforate membrane and cause liquid droplets to be emitted from the perforate membrane and projected generally away from the liquid container.

The present invention relates to a method and apparatus for atomizing and vaporizing liquid. An apparatus works as a fluid capsule and pumps air saturated with liquid and carrying a mist of tiny droplets sized at or less than about 2 μm in diameter. The pump may have a vibrator attached to the liquid reservoir to cause liquid to move up through the outlet valve and out through an orifice located on the top of the capsule. One or more droplets of liquid ejected from the ejector may be heated and vaporized into the air. The design of the fluid capsule ensures that there is no larger droplet size of liquid that is allowed to come out. The fluid can be air-freshener, air-sanitizer, disinfectant, insect repellent or any other liquid.

A droplet delivery device includes an ejector mechanism with an ejector mesh or similar substrate with apertures that is treated by one or more of coatings, roughening, metal layer deposition and laser ablation to provide desirable production and size of droplets, such as in an inhaled aerosol from the device.

A vaporizer includes: an ultrasonic vaporization assembly having: a liquid inlet surface and a first support surface surrounding an edge of the liquid inlet surface, the first support surface and the liquid inlet surface being located on a same side of the ultrasonic vaporization assembly such that liquid enters the ultrasonic vaporization assembly from the liquid inlet surface to be vaporized to form liquid vapor; and a heating assembly attached to the first support for preheating liquid reaching near the liquid inlet surface.

A liquid ejection device includes: a nozzle through which a liquid is ejected; a liquid transport pipe that transports the liquid to the nozzle; and a vibrator that is configured to generate a vibration. The vibrator is in contact with at least one of the liquid, the nozzle, and the liquid transport pipe, and a vibration frequency generated by the vibrator is higher than a self-droplet formation frequency, the self-droplet formation frequency is defined as the number of droplets of the liquid passing through a predetermined position per unit time in a state in which the vibrator does not generate the vibration.

A device and method for delivering a fluid as an ejected stream of droplets during inhalation uses inertial filtering to cause a first plurality of droplet particles generated by an ejector mechanism to pass through an airflow exit while a second plurality of droplet particles having a greater mass mean aerodynamic diameter than the first plurality of droplet particles fails to pass through the airflow exit.

An electronic cigarette, comprising a shell and a power supply installed in the shell, and the electronic cigarette further comprises a tobacco bin which is provided in the shell and communicates with the outside air, and a suction nozzle which communicates with the tobacco bin; and a piezoelectric ceramic piece which clings to the tobacco bin is provided in the shell, the piezoelectric ceramic piece is a bearing surface of the tobacco bin on which a tobacco material is loaded as well as a heating surface of the tobacco bin, and the piezoelectric ceramic piece is electrically connected with the power supply. The electronic cigarette has a simple atomization mode and directly atomizes the tobacco material by means of the high frequency vibration and heat of the piezoelectric ceramic.
