The ejector mechanism may have a centro-symmetric configuration with a lead free piezo actuator and may be covered by an auto-closing cover.

Methods, systems, and devices are provided for generating a mist. In one embodiment, a fluid delivery device is provided that includes a housing, a fluid vaporizer disposed within the housing and configured to receive fluid and to produce an aerosol mist of liquid particles from the fluid, and a pump configured to accelerate the aerosol mist produced by the fluid vaporizer. Methods are provided for producing a mist, and the methods can include delivering a fluid to a fluid vaporizer that generates a first mist. The fluid vaporizer delivers the mist to a pump that generates a second mist from the first mist.

The present disclosure provides an aerosol delivery device that comprises a housing defining an outer wall, and further including a power source and a control component, a mouthpiece portion that defines an aerosol exit path, a first reservoir configured to contain a first liquid composition, a second reservoir configured to contain a second liquid composition, a first atomization assembly configured to vaporize the first liquid composition to generate a first aerosol having a first aerosol particle size, and a second atomization assembly configured to vaporize the second liquid composition to generate a second aerosol having a second aerosol particle size. The first liquid composition may be different than the second liquid composition, and the first particle size may be different than the second particle size.

An accurately mixed fragrance can be provided. A fragrance generation device includes: a first ultrasonic vibrator provided in a water container that contains water and used for atomizing the water; a first emission hole used for emitting the water atomized by the first ultrasonic vibrator; a plurality of second ultrasonic vibrators provided in a plurality of perfume containers that individually contain multiple types of perfumes, respectively, and used for atomizing the perfumes; a plurality of second emission holes arranged around the first emission hole and used for emitting the perfumes atomized by the plurality of second ultrasonic vibrators; and a control unit configured to control driving of the first ultrasonic vibrator and the second ultrasonic vibrators.

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.

The present invention includes and provides a method of delivering a medicament to an eye of a subject in need thereof a solution, the method comprising: (a) providing droplets containing the medicament with a specified average size and average initial ejecting velocity; and (b) delivering the medicament to the eye, where the droplets deliver a percentage of the ejected mass of the droplets to the eye.

The present invention relates to a device (10) for supplying a mist of liquid (F). The device (10) is used in combination with a container (20) with an opening (200) for containing the liquid (F). The device (10) includes a main body (100) comprising: (i) a center axis (C); (ii) a liquid chamber (110) formed inside the main body (100), into which a predetermined amount of liquid (F) can be taken up; (iii) a first port (112) formed in a base wall (114) of the main body (100) forming a bottom surface (116) of the liquid chamber (110) so as to face the opening (200) when the device (10) and the container (20) are combined with each other, through which the liquid (F) can flow; (iv) a second port (118) formed in the base wall (114) at a position different from the position where the first port (112) is formed so as to face the opening (200) when the device (10) and the container (20) are combined with each other, through which the liquid (F) can flow; and (v) an aperture (120) connected to the liquid chamber (110), through which a mist of liquid (F) can be released to the outside of the main body (100). The device (10) further includes: a connecting section (122) provided on the main body (100) so as to extend from it in a direction away from the base wall (114) and used for connecting the container (20) to the main body (100); an atomizing element (124) interposed between the liquid chamber (110) and the aperture (120) to atomize the liquid (F) taken up in the liquid chamber (110) and release a mist of the liquid (F) to the outside of the main body (100) from the aperture (120); a first valve (126) mounted on the main body (100) corresponding to the first port (112), wherein the first valve (126) permits the liquid (F) in the container (20) flowing into the liquid chamber (110) through the first port (112) under the influence of gravity, and prevents the liquid (F) in the liquid chamber (110) flowing into the container (20) under the influence of gravity; and a second valve (128) mounted on the main body (100) corresponding to the second port (118), wherein the second valve (128) prevents the liquid (F) in the container (20) from flowing into the liquid chamber (110) through the second port (118) under the influence of gravity, and selectively permits or prevents the liquid (F) in the liquid cha
