A liquid freshening composition is provided. The liquid freshening product includes about 0.5 wt. % to about 15 wt. % isopropyl myristate, by weight of the liquid freshening composition and greater than 40 wt. % of one or more perfume raw materials. The liquid freshening composition has a vapor pressure at 25° C. of about 0.03 Torr to about 1.0 Torr. The liquid freshening composition may be used with air freshening products having a delivery engine such as a wick, breathable membrane, gel, porous and semi-porous substrate, and combinations thereof.

Methods, devices and systems are described for digitally creating new scents or digitally dispensing gas, vapor, or liquid substances. A device includes a container or replaceable cartridge including one or more chambers containing one or more scented substances; a housing structured to include a compartment to hold the cartridge, an opening to allow the one or more scented or unscented substances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to deliver a scented substance from the corresponding chamber to the opening for delivering a scent from the one or more scented substances; and an actuator switch arranged in a corresponding transporting channel and rapidly operable to move between an open position and closed position based on an applied signal to selectively allow passage of the scented or unscented substance from the corresponding transporting path.

An ozone treatment device includes an ozone destruct module and an ozone generator mounted within a housing. The ozone destruct module and the ozone generator are mounted between corresponding air inlets and air outlets formed in the housing. The ozone treatment device also includes a controller mounted to the housing. The controller is configured to generate ozone with the ozone generator for a first time period and to automatically destruct ozone with the ozone destruct module for a second time period following the first time period. In certain implementations the treatment device includes an input device for receiving an operator input. In such cases the controller can determine the first and second time periods based on the operator input.

A sanitisation system comprising a chemical vaporising apparatus for storing and vaporising a sanitising chemical com- position. The chemical vaporising assembly comprising a housing configured to receive and retaining one or more sanitising chemical composition containing cartridges, a vaporiser located within the housing, the vaporiser configured to receive and convert a sanitising chemical composition in the chemical containing cartridges into a vapor, and an air purifier assembly located within the housing, the air purifier assembly configured to purify the air by removing vaporised sanitising chemical composition from the air and maintain a low humidity environment.

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 benefit agent delivery system can deliver benefit agents on demand. The benefit agent delivery system comprises a first electrode layer, a microcell layer comprising a plurality of microcells, and a porous second electrode layer. Each of the plurality of microcells are filled with a liquid mixture comprising reverse micelles in a hydrophobic liquid that are formed from a polar liquid, a surfactant or stabilizing particles, and a benefit agent. Application of an electric field across a microcell layer causes an increase in the rate of release of the benefit agent of the microcell through the porous second electrode layer.

A sintered body for use as a liquid reservoir in an electronic cigarette, medication administering devices, in thermally heated evaporators for fragrant substances is provided. The sintered body is made of open-pore sintered glass and has a porosity of greater than 50 vol %. The average pore size is in a range from 1 to 450 μm. The glass of the sintered body has a transition temperature T.sub.g of at least 450° C.

A compact diffuser integrates an atomizer and droplet separator into a surrounding sleeve, threadable to a bottle neck as an assembly. The assembly fits into a base, housing a motor and air pump, sealing the sleeve to a silo in the housing. Controls set time span of intermittent operation, intervening delay, and volumetric flow rate. The assembly pops into (and out of) the top end of a silo in the base, registering (aligning) circumferentially and axially to seal an air path from the pump to the atomizer. Access for applying force to the bottom of the assembly facilitates popping out the assembly when empty, or to simply change scent by changing out the assembly. Entire assemblies may be stored to simplify exchange and reduce chances for spills from reservoirs.

A decontamination assembly, for pharmaceutical applications includes at least one chamber to be decontaminated (4) having a decontamination liquid storage tank (36) by which several atomizers (A, B, C. D) disposed in the chamber to be decontaminated (4) for producing a decontaminant aerosol can be supplied with decontamination liquid using valves (27) which can be controlled by electronic control, the atomizers (A, B, C, D) being in fluid communication with a ring conduit (32) having an inlet (33) and a separate outlet (34) by the valves (27), decontamination liquid from the decontamination liquid storage tank (36) being conveyable into the inlet of the ring conduit by a pump (35) and decontamination liquid flowing out of the outlet of the ring conduit back into the decontamination liquid storage tank (36), and a pressure adjustment mechanism (37) for keeping the pressure in the ring conduit (32) at a predefined liquid pressure range assigned to the ring conduit (32). A measuring mechanism (40) for determining a total volume of decontamination liquid dispensed to the atomizers (A, B, C, D) during a decontamination cycle includes a weighing mechanism (41) for determining a decontamination liquid volume in the decontamination liquid storage tank (36).
