A scent diffuser device electrically charged in a wireless manner contains: an aromatic element, a wireless charger configured to convert first electric currents into electromagnetic signals, and a heater configured to receive and to convert the electromagnetic signals into second electric currents, by which the heater operates. The heater includes a case, a container, a heat insulator, a wireless charging receiver, and a heating unit. The case has an accommodation chamber, and the container has a holding space, a bottom fence, and a thermal conductor. The heat insulator includes two open segments so as to accommodate the container, the heating unit, and the thermal conductor. The holding space is configured to accommodate the aromatic element, and the wireless charger is electrically connected with a power supply so as to produce a magnetic field to send the electromagnetic signals and energy.

A device for diffusing a liquid into a vapor proximate a face of a person comprises a U-shaped enclosure that has two legs connected with a back portion for resting on shoulders of the person around a neck of the person. A top side of the enclosure has at least one diffusion port. A control circuit disposed within the interior space of the enclosure includes a controller, at least one user interface, a power source, and a diffusion mechanism connecting a reservoir containing the liquid with the at least one diffusion port. Wherein the person has a smart phone running a software application, the controller may further include a processor, a non-volatile memory, and a wireless network module adapted to wirelessly communicate with the software application running on the smart phone to control a diffusion rate, an on/off status of the device, and a timer.

An air freshening device is provided. The device includes a water-based fragrance emitter including water, a water absorbing polymer and a fragrance composition. The fragrance composition includes from about 3% to about 70% by weight of at least one fragrance ingredient exhibiting a standard equilibrium headspace concentration (HS.sub.i.sup.0) below about 100 μg/L. The water-based fragrance emitter provides a working signal and an end of life signal upon evaporation. The air freshening device is a warming device.

A vapor chamber includes a wick structure created by an additive selective laser sintering process. The wick structure includes a substrate, a first copper powder layer, a second copper powder layer, and a plurality of additional layers. The first copper powder layer is deposited across the substrate, wherein the first copper powder layer is subsequently selectively fused via a fusing instrument. The second copper powder layer is deposited across the first copper powder layer, wherein the second copper powder layer is subsequently selectively fused via the fusing instrument. Additionally, a plurality of additional copper powder layers are deposited wherein each additional layer is deposited on the previous layer, wherein each of the additional copper powder layers is selectively fused with a predetermined structure.

An electronic scented candle is described that includes a movable flame-shaped component, a shell including an installation chamber, a fragrance container that is removably positioned inside the installation chamber and a scent chamber. An electric fan is positioned within the shell to drive the air into the scent chamber and a scent outlet coupled to the scent chamber to allow the fragrance material to leave the scent chamber and to reach an external environment of the electronic scented candle. The electronic candle also includes a receptacle for connecting a power cord on a bottom surface of the electronic candle. The bottom surface includes a plurality of protruding stands that provide a space to allow the power cord to be connected to the receptacle and be routed below the bottom surface.

A scent dispenser may comprise a vial retaining mechanism, a heating element, vial sensor, and a controller. The vial retaining mechanism includes a vial coupling that removeably retains a vial containing a scented solution. The includes a wick extending from a cavity of the vial through an opening of a neck of the vial. The heating element is shaped to receive and heat the wick of the vial. The vial sensor includes an array of sensor pads that are arranged in alignment with the vial retained by the vial coupling. The controller is electrically coupled to the heating element and electrically coupled to the array of sensor pads. The controller regulates a temperature level of the heating element, and receives signals from the array of sensor pads and processing the signals to determine a fluid level of the vial.

A fragrance suitable for a user can be provided. A mobile terminal includes: an acquisition unit that acquires a psychosomatic state from a physiological index of a user; an input unit that inputs future information of the user; a determination unit that determines a recipe including one or more types and a mixing ratio of one or more perfumes based on the psychosomatic state and the future information; and a communication unit that transmits the recipe to a fragrance generation device.

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 antibacterial air freshening product for an interior environment. The product includes a container containing 1 ml to 50 ml of a freshening composition in fluid communication with a membrane. The composition is substantially free of a surfactant and has from 0.5% to 20% of a volatile aldehyde mixture, by weight of the composition. The volatile aldehyde mixture includes a C5 to C8 unbranched unsubstituted linear alkenal and a C9 to C14 unbranched unsubstituted linear alkenal. A weight ratio of the C5 to C8 unbranched unsubstituted linear alkenal to the C9 to C14 unbranched unsubstituted linear alkenal is from 3:1 to 1:3.
