A volatile material dispenser includes a base that houses a printed circuit board. The volatile material dispenser also includes a stand assembly and a shroud. The stand assembly is coupled with the base. The stand assembly includes a platform, a stand that extends from the platform, and a manifold that extends from the stand. The manifold contains a circular piezoelectric element. The shroud is positioned on the base. The shroud defines a chimney that is centered along a longitudinal axis. The manifold includes an annular wall that extends from the manifold. A spring is disposed within the manifold and is coaxial with the annular wall. A top end of the spring is wrapped around the annular wall and a bottom end of the spring applies a force against the piezoelectric element.

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.

A system to provide media (e.g., scent, therapeutics, other substances) includes a dispenser that may include a reservoir, an actuator (e.g., nebulizer), and an outlet through which a vapor or aerosol may be supplied or dispensed, the vapor or aerosol, for example comprising readily-soluble droplets having a median size range of approximately 2 microns to approximately 50, 20, or 10 microns for introduction to vessel. An interface is positionable over an opening of the vessel to close the opening while allow media to be dispensed into the interior of the vessel, thereby retaining the dispensed media until taken in by a user. The interface (e.g., annular plate) has a pair of opposed major surfaces, and the first major face supported on a rim of the vessel, with the dispenser supported on the second major face in an inverted orientation. A sensor may sense orientation, and cause an actuator (e.g., nebulizer) to dispense media when in the inverted orientation or otherwise titled for normal.

A volatile material dispenser includes a base that houses a printed circuit board, a stand assembly that is coupled with the base, the stand assembly including a platform, a stand that extends from the platform, and a manifold that extends from the stand, the manifold containing a circular piezoelectric element. The dispenser further includes a shroud that is coupled with the stand assembly and defines a chimney, and a refill comprising a wick, the refill being removably coupled with the manifold. The manifold includes a cylindrical wall that extends upward from the manifold, a spring is disposed within the manifold and is coaxial with the cylindrical wall, and a top end of the spring is wrapped around the cylindrical wall and a bottom end of the spring applies a force against the piezoelectric element.

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 aromatic deodorizing device generates a deodorant component that removes a target malodor. The aromatic deodorizing device includes a sensor that detects an index indicating an odor strength of the target malodor, a plurality of different aromatic deodorants, and a switching unit that changes the aromatic deodorant that is to be a source of the deodorant component in accordance with a detection value of the sensor.

A plume cleaning system for a toilet is integrated with a toilet. In one example, a plume cleaner assembly adjacent to a toilet seat is independently removable with respect to the toilet seat. The plume cleaner assembly may include a plume cleaner, apertures, and a fan positioned to draw plume air through the plurality of apertures for treatment by the plume cleaner and expel the treated plume air out of the plume cleaner assembly in a direction at an angle to the apertures. In another example, a plume cleaner assembly with the toilet seat may include at least a fan, an electrostatic collector, and a mist generator. In another example, a plume cleaner assembly is integrated in a tank of the toilet to generate a sanitization fluid that is channeled into the toilet bowl through an overflow tube and/or rim channels.

Atomizers and methods for operating atomizers for dispersing vapor into the ambient air are disclosed. Liquid from a vessel connected to the atomizer may be pumped to a first chamber having an atomizing element at or near the bottom of the first chamber. The atomizing element may convert the liquid to a vapor, and a fan may push air into the first chamber, causing the vapor to be dispersed into the ambient air through apertures at or near the top of the first chamber. Liquid remaining in the first chamber may be pumped back to the vessel, while the fan continues to run to dry the components in the first chamber.

A battery-operated ultrasonic diffuser includes a rechargeable lithium-ion battery and a liquid management system that allows a user to safely move the diffuser when it is full.

A humidifier includes a first housing, a second housing, a water atomization module, an essential oil delivery module, and an essential oil container. The first housing includes an outer wall including a recess. The second housing is fixedly embedded in an upper part of the recess. The water atomization module is disposed in the first housing. The water atomization module includes a first container, a water passage, and an ultrasonic atomizer. The water flows out of the first container, enters the water passage into the ultrasonic atomizer, and is atomized to produce mist. The essential oil delivery module is disposed in the second housing. The essential oil container is connected to the essential oil delivery module. The essential oil delivery module is configured to transfer essential oil from the essential oil container to the water passage so that the essential oil and the water are atomized together.
