A combination salt lamp and aroma/essential oil diffuser includes: a housing with an outlet for mist exiting the housing and an open space, a water tank inside the housing for storing liquid having a passageway that connects to the mist outlet and can disperse nebulized mist outwardly, a nebulizing assembly within the water tank to nebulize the liquid in the water tank, a salt crystal mineral that sits in the open space of the housing, a heating assembly with a heating element adjacent the salt crystal, a fan assembly inside the housing, and a power assembly for the nebulizing assembly, the heating assembly, and the fan assembly.

A dry diffuser is disclosed which avoids safety and transport issues typical of liquid diffusers, candles and wax melts and provides systematic controlled diffusion of fragrance (or other active material) over relatively long periods with a programmable user interface.

An air treatment system is disclosed that includes a modular configuration whereby a fan module, filter module, and humidifier module may couple together to provide a plurality of air treatment solutions. In more detail, the modules can stack end-to-end in a vertical configuration. The modules may electrically couple to each other via a common electrical bus and enable a controller disposed in the fan module (or other module) to control fan flow rates, direction, and humidity. The fan module can include an articulating nozzle capable of directing airflow in virtually any direction and angle about an environment. The fan module can further include an inlet arrangement that can selectively restrict external air from entering the fan module housing when the fan module is fluidly coupled to the filter module. Thus, the fan module may generate air flow from exclusively filtered air to minimize or otherwise reduce bacterial/mold growth within the fan module housing.

A method of atomizing a fluid composition is provided that includes dynamically measuring the minimum-required actuation energy for the fluid composition. The method includes the steps of: connecting a microfluidic cartridge with a housing of a microfluidic device, the microfluidic cartridge comprising a reservoir containing the fluid composition and a microfluidic die in fluid communication with the reservoir; the microfluidic device comprising a controller; measuring the minimum-required actuation energy for the fluid composition at a first time; atomizing the fluid composition in a first atomization period; measuring the minimum-required actuation energy for a fluid composition at a second time that is after the first time; and atomizing the fluid composition in a second atomization period.

A spatial environment management system includes an acquisition unit, a determination unit, a device and a control unit. The acquisition unit acquires at least one of an image of a target space and a sound of the target space. The determination unit determines whether an odor emitting object is present in the target space, based on at least one of the image and the sound acquired by the acquisition unit. The device includes at least one of an airflow producing mechanism and a deodorizing mechanism. The control unit controls the device such that the device treats an odor when the determination unit determines that the odor emitting object is present in the target space.

Apparatuses, systems, methods, and computer program products are disclosed for a diffuser and interchangeable cover. A complete diffuser includes a diffuser element that disperses a liquid into air within a diffuser chamber of the complete diffuser. A complete diffuser includes a lid shaped to at least partially enclose an upper opening of a diffuser chamber. A cover is removably couplable to a complete diffuser over a diffuser lid so that a dispersed liquid passes through one or more openings in the cover. A cover includes one or more decorative features having a different external shape than a complete diffuser that receives the cover.

A volatile composition dispenser and methods of detecting the replacement of a cartridge of volatile composition are provided. The cartridge of the volatile composition dispenser includes one or more reservoirs, with each reservoir containing a volatile composition. A method of volatilizing the volatile composition includes operating the evaporative assistance elements with varying energy over a total emission program. Replacement of the cartridge by a user when the volatile composition dispenser is disconnected from an external power source is detected in order to reset the total emission program when reconnected to the external power source.

Apparatuses, systems, methods, and computer program products are disclosed for a diffuser and one or more removable diffuser covers. A removable diffuser cover comprises one or more decorative features. A cavity in a diffuser cover is shaped to receive a complete diffuser. A complete diffuser comprises a diffuser element that disperses a liquid into air within a diffuser chamber and a lid shaped to at least partially enclose an upper opening of the diffuser chamber. One or more openings are positioned to receive a dispersed liquid from a lid of a complete diffuser within a cavity and to allow the dispersed liquid to pass to an exterior of a removable diffuser cover.

Disclosed is an air purification system (10) comprising an air purifier apparatus (50) for removing a pollutant from air, a sensor (21, 23) for sensing a concentration of the air pollutant and a scent release apparatus (40) responsive to a scent release signal, wherein the air purification system further comprises a processor (31) adapted to monitor the pollutant concentration from sensor data received from the sensor and to generate the scent release signal upon the monitored pollutant concentration falling below a defined threshold. Also disclosed is a method of generating a scented atmosphere in a room housing an air purification apparatus (50) for removing a pollutant from the air in the room.

A mist generator is a standalone device that improves the internal sterility of controlled forced air systems. Sterilizing mist is generated when forced air circulates above or through a liquid disinfectant. The disinfectant is taken up into the circulating air and distributed throughout the internal structure of the system, sterilizing its internal surfaces. The mist generator contains no ionizers, atomizers, ultraviolet lamps, or other electric or mechanical devices.

In one embodiment, the mist generator has a chamber with an inlet adapted for attachment to a blower or duct delivering forced air into the chamber. The chamber also includes an output duct or aperture adapted for attachment to a second hose which, in turn, is adapted for attachment to the inlet of the blower for delivery of disinfectant-misted air through internal components of the blower. Alternatively, there is used a disinfectant filter formed as a sterilizing grid having a screen coated with a soft porous surface material impregnated with a liquid disinfectant. The soft porous surface material releases said liquid disinfectant when forced air moves through the filter and through the system. In both embodiments, sterile water can be introduced to take up residual disinfectant and the vapor is captured in a dry filter or desiccant material and removed from the system.

In the alternative embodiment, the sterilizing mist produced by the uptake of liquid disinfectant into circulating air and distributed throughout the forced air system can be formed when air from a blower or air handler is circulated across a sterilizing screen with a porous surface material impregnated with a liquid disinfectant. The antimicrobial mist is distributed throughout the system and acts to disinfect the internal surfaces and components. Additional water may be added to the sterilizing screen and distributed similarly by the forced air. A dry, desiccating filter, remote from the blower, traps the water and any residual disinfectant as it exits from the system. A dehumidifier, if installed, may also be used to remove water and can be readily emptied.

The mist generator improves the sterility of the blower and mitigates microbial contamination of forced-air delivery systems.
