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.

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 invention provides an atomization equipment which comprises a lid and a shell. The lid is configured to have multiple gas chambers, and the lid engages with the shell. Thereafter, the shell comprises a plurality of windows, a tank, at least one vibrator, a liquid input, a liquid stopper and at least one blower. The multiple gas chambers match and communicate with the plurality of windows, and the at least one vibrator are configured at bottom of the tank. On the other hand, the liquid input is configured on the side wall of the tank, and the liquid stopper be detachably closed the liquid input. At last, the at least one blower communicates with the tank.

A fluid diffuser for atomization of essential oils can have a flexible seal used to reduce internal pressure of an air chamber adjacent to the atomizer. It can also use a cover and a sensor to control the operation of the atomizer based on the position of the cover. An atomizer housing portion of the diffuser can be removable and replaceable relative to a lower portion of the housing.

An atomizer device can include a container for storing liquid for atomization, the container defining a top portion and a bottom portion, the top portion defining a mist opening. An ultrasonic transducer can be located at the bottom portion of the container and configured to generate waves in the liquid. A sleeve can extend from the bottom portion toward the top portion of the container. The sleeve can be configured to direct the waves along a longitudinal axis of the sleeve. A float can be located within the sleeve and be configured to move along the longitudinal axis of the sleeve. The float can define a through hole, wherein the waves are concentrated toward a surface of the liquid by passing through the through hole.

In one arrangement, a vibration system includes a vibratable plate, a support member surrounding the vibratable plate, and a vibration-inducing member surrounding the support member. The vibration-inducing member is configured to radially expand and contract against the support member so as to produce axial vibration of the vibratable plate. In another arrangement, the vibratable plate has an outer circumference; a tubular member is concentrically disposed about the outer circumference of the plate, and an annular vibration-inducing member is concentrically disposed about the outer circumference of the tubular member. The vibration-inducing member is preferably a piezoelectric ring that is radially expandable and contractable against the wall of the tubular member to cause the plate to vibrate in the axial direction.

An atomization device includes a liquid storing member that stores a liquid therein, a carrier detachably assembled to the liquid storing member, an opener disposed on at least one of the liquid storing member and the carrier, and an atomizing module that is assembled to at least one of the liquid storing member and the carrier. The opener is configured to form an opening on the liquid storing member. The atomization device has a buffering chamber arranged between the atomizing module and the opening of the liquid storing member, and a volume of the buffering chamber is less than a volume of the liquid. The liquid storing member can be pressed to change an inner pressure thereof, such that a part of the liquid is driven to flow from the opening into the buffering chamber for an atomizing process of the atomizing module. The buffering chamber can receive the liquid stored in the liquid storing member over multiple times, such that the atomization device can atomize the liquid over multiple times through the buffering chamber.

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.

A surface acoustic wave module (SAW module) includes a piezoelectric element substrate including a piezoelectric body, an IDT disposed on a front surface of the piezoelectric element substrate and including a comb-like electrode pair, and a coating layer covering the piezoelectric element substrate and the IDT. The coating layer is disposed on the front surface of the piezoelectric element substrate, an end surface of the piezoelectric element substrate, and a corner portion between the front surface of the piezoelectric element substrate and the end surface of the piezoelectric element substrate.

A fluid diffuser for atomization of essential oils can have a flexible seal used to reduce internal pressure of an air chamber adjacent to the atomizer. It can also use a cover and a sensor to control the operation of the atomizer based on the position of the cover. An atomizer housing portion of the diffuser can be removable and replaceable relative to a lower portion of the housing.
