A scent delivery system includes a housing that releases a volatile substance from a porous body into the air. The housing may be part of a scent dispersion device that includes volatilization as directed by a fan and a controller within the housing.

Methods and apparatus for vaporizing liquid into the surrounding environment, including directing liquid from a liquid source through an inverse-opal wicking structure to a vaporization port where the vaporization port is formed by a through-hole in a structure connecting a first side of the structure to a second side, with all dimensions ranging from 10 um to 300 um, that is in fluid communication with the liquid source and the surrounding environment so that fluid is transported through the vaporization port between the first and the second side. The methods and apparatus includes plurality of heating elements that may be individually and/or selectively addressable by at least three electrode leads.

A wax warmer includes a body, an electrical assembly, a base plate, and a sleeve. The electrical assembly is positioned within an interior space of the body and includes an electrical cord that extends outside the body. The sleeve forms an electrical barrier positioned within the interior space and surrounding the electrical assembly. The sleeve is coupled to the base plate and a portion of the electrical cord that passes through an opening in the sleeve is retained by the base plate and the sleeve.

An apparatus for cleaning exhaust gas. The apparatus includes a housing having an upstream end configured to receive exhaust gas and a downstream end configured to release the exhaust gas. At least one coalescing filter layer and a catalyst filter layer are disposed within the housing. The catalyst filter layer includes molded sintered pellets formed from a porous material and a non-precious metal catalyst. The molded sintered pellets create a porous area for coalescing oil mist, and the catalyst hydrogen peroxide.

The disclosure herein concerns a method including receiving at a computer at least one target value of a scent parameter for an environment that is remote from the computer, receiving at the computer a sensed parameter of the environment, and controlling, via the computer, diffusion of a liquid from a source of the liquid in fluid communication with at least one scent diffusion device to achieve the target value of the scent parameter, wherein controlling includes setting or adjusting an operation parameter of the at least one scent diffusion device in response to the sensed parameter.

A fragrance delivery apparatus contains: a body, a fan, a power base, and a case. The body includes an accommodation chamber defined therein, a receiving groove formed above the accommodation chamber, an air vent arranged on a first side of the body and communicating between the accommodation chamber and the receiving groove, and multiple elongated orifices formed on a second side of the body opposite to the first side of the body and communicating with the accommodation chamber. The fan is accommodated in the accommodation chamber and draws external gas from the multiple elongated orifices. The power base is connected with the body and shields the accommodation chamber, and the power base is configured to supply power and is electrically connected with the fan. The case is removably connected outside the body and includes a spray nozzle which is in communication with the receiving groove.

A method for fragrancing and/or deodorizing a cleaning appliance is disclosed. The method involves capturing first information or obtaining captured first information indicative of an odor load in the interior of the cleaning appliance, producing fragrancing and/or deodorizing information based at least in part on the captured or obtained first information or outputting the captured first information in order to produce fragrancing and/or deodorizing information of this type, and initiating fragrancing and/or deodorization by employing at least one actuator for releasing a fragrancing and/or deodorizing agent based on the fragrancing and/or deodorizing information produced. A corresponding dosing device, a device for carrying out and/or controlling the method, and a system with one or more devices for carrying out and/or controlling the method are also disclosed.

An electronic scented candle is described that includes a flame piece, a shell including an installation chamber, a fragrance container that is removably positioned inside the installation chamber, a scent chamber, and a liquid suction channel positioned within the fragrance container. One end of the liquid suction channel protrudes from the fragrance container into the scent chamber and anther end of the liquid suction channel is positioned within the fragrance container to draw a fragrance material from the fragrance container to the scent chamber. A scent outlet in communication with the scent chamber allows scent from the chamber to reach an external environment of the electronic scented candle, and an air inlet in communication with the scent chamber directs air from the external environment to the scent chamber. A heating device heats the content of the scent chamber to allow rapid dissemination of the scent chamber into an external environment.

An air fragrance diffuser system for use in an automobile includes a battery and an electronic control system communicably coupled to a wireless transceiver associated with a user. The diffuser system includes an air pump for generating a pressurized air. The diffuser system further includes an atomizer device pneumatically coupled to the air pump for receiving the pressurized air to convert fragrance oil stored in the atomizer device into fragrance mist using the pressurized air based on a jet nebulization process. In an embodiment, the diffuser system further includes a transmission system coupled to the atomizer device for receiving the fragrance mist, and for providing the fragrance mist into a passenger compartment of the automobile. In another embodiment, the transmission system provides the mixture into the passenger compartment using existing vents of a Heating, Ventilation, and Air Conditioning (HVAC) system of the automobile.

Provided is a discharge device that can improve the efficiency of generating reactive species. The discharge device includes a discharging unit, which has a tip end and discharges from the tip end in response to an application of a voltage, an induction electrode, which forms an electric field between the induction electrode end the discharging unit, and a second electrode, which is disposed between the discharging unit and the induction electrode and receives a voltage having a polarity the same as a polarity of the voltage applied to the discharging unit.
