Abstract
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.
Claims21
An atomizer device, comprising:
- 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 located at the bottom portion of the container and configured to generate waves in the liquid;
- a sleeve extending from the bottom portion toward the top portion of the container and having a longitudinal axis and a sleeve width, the sleeve configured to direct the waves along the longitudinal axis, the sleeve defining an opening configured to allow liquid to enter the sleeve from the container, the opening extending along a majority of a height of the sleeve;
- and
- a splash guard attached to a top end of the sleeve and configured to prevent liquid from exiting the mist opening, the splash guard having an arched top portion and a guard width greater than the sleeve width;
- a set of openings defined by the splash guard and the sleeve between the splash guard and sleeve to permit vapor to exit the sleeve.

An ultrasonic atomizer, comprising:
- a container for storing liquid, the container comprising a sidewall that at least partially defines an internal volume;
- a piezoelectric transducer configured to propagate vibrations in the liquid;
- a guide wall positioned in the internal volume and surrounded by the sidewall, the guide wall configured to constrain the vibrations, the guide wall including a guide wall width and a slit opening configured to allow liquid to enter the guide wall from the container, the slit opening extending along a majority of a height of the guide wall;
- and
- a splash guard having a guard width greater than the guide wall width, the splash guard having an arch-shaped top portion attached to a top end of the guide wall, wherein a set of openings are defined between the guide wall and the splash guard, wherein vapor in the guide wall is configured to exit the guide wall through the set of openings between the guide wall and the splash guard.
A method for atomizing liquid, comprising:
- providing an ultrasonic transducer at a bottom portion of a container holding a liquid, the ultrasonic transducer being configured to propagate waves toward a surface of the liquid;
- and
- positioning a sleeve in the container such that a longitudinal axis of the sleeve corresponds to a propagation direction of the waves, the sleeve configured to at least partially constrain the waves along the longitudinal axis;
- positioning a floating nozzle within the sleeve, the floating nozzle defining a tapering opening and having a buoyancy configured to keep a top surface of the floating nozzle and a top end of the tapering opening flush with the surface of the liquid;
- and
- attaching a splash guard to the sleeve.
