The process includes a treatment step during which a liquid containing a biocidal and/or plant-protection product or a mixture of biocidal and/or plant-protection products is evaporated and injected into the internal atmosphere of premises, the liquid being evaporates at a temperature of less than 50° C., the product vapour concentration in the internal atmosphere of the premises being kept at greater than 10% of a saturation concentration of the vapour of said product in said atmosphere at said temperature for a saturation duration of greater than 12 hours.

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.

Aspects of the present disclosure include a method of managing scent in an environment, which includes disposing at least one scent diffusion device within an environment, wherein the at least one scent diffusion device comprises a communications facility that enables transmitting signals to and receiving signals from a remote computer, receiving at least one target value of a scent parameter for the environment at the remote computer, and controlling, via the remote computer, diffusion of a liquid from a source of the liquid in fluid communication with the at least one scent diffusion device to achieve the target value of the scent parameter. Controlling a diffusion rate of the liquid includes altering at least one of a voltage and a duty cycle applied to at least one component of the diffusion device.

An improved vaporizer part, such as an evaporator element of a disinfection device is for an aqueous solution of hydrogen peroxide. The evaporator element includes one, and/or a branching, meandering structure, in which the straight sections of the groove are joined by 180-degree meanders near edges of the evaporator element. An end pit with an overflow guard is for overflown liquid. Heating elements are used both in connection with the evaporator element to enhance evaporation and on the inner surfaces of the device to prevent condensation. An air blower creates desired vortices near the surface of the evaporator element. The air control element also makes the air flow more laminar. The actual travel of the liquid on the evaporator element functions gravitationally on an inclined surface, and the capillary effect increases the evaporating area of the liquid. A disinfection device includes the vaporizer part.

A portable air filtration apparatus capable of rapid and efficient room air turnover and recirculation of filtered and decontaminated air with eradication of both microorganisms and biological agents. The invention relates to a compact device that can be used in ultra-clean air purification using a multi stage electrostatic precipitation and air filtration with disinfection and eradication of both microorganisms and biological agents by the application of ultraviolet light radiation. It can be used in any application where space, lower cost or ultra-fine particulate filtering is needed; such as in clean rooms and surgical suites. The device is extremely efficient for purifying contaminated air from entrained dust and organic substances without using chemicals and physical filters, and it is hygienic and fireproof. The device including its multi stage electrostatic precipitator with the filter, connecting, releasing tubes and the fan is easy to clean and can be portable.

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.

Fragrance dispensers with features that are capable of reducing wastage of fragrance, or of conserving fragrance, are disclosed. Such a fragrance dispenser may have a configuration that collects fragrance that is expelled from the fragrance dispenser, but has not vaporized or atomized sufficiently to dissipate into the environment, as well as fragrance that condenses immediately after it has been expelled from the fragrance dispenser. A spill-resistant bottle that may be used with a fragrance dispenser has a shape that orients an opening of the bottle in a somewhat upward orientation to prevent fragrance from spilling out when the bottle is tipped over. Fragrance dispensers with configurations that generate vortices to deliver fragrance into the surrounding environment are also disclosed.

A cartridge that is releasably connectable with a housing of a microfluidic delivery device is provided. The cartridge has a reservoir for containing a fluid composition and a microfluidic die in fluid communication with the reservoir. The microfluidic die is configured to dispense substantially all of the fluid composition in a horizontal direction or downward direction relative to horizontal. The cartridge also includes an air flow channel disposed below the reservoir. The air flow channel extends from a fan to an air outlet. The air flow channel comprises a first region disposed adjacent to a fan, a second region disposed adjacent to the air outlet, and a third region joining the first and second regions. At least the second region is angled upward to the air outlet, relative to horizontal.

Described is a scent producing assembly having a self-contained module comprising an absorptive matrix infused with a volatile composition and a housing. The housing may include a receptacle shaped to receive the module, wherein the housing has a stowed position and a deployed position. In the stowed position, the receptacle may be contained within an interior of the housing. In the deployed position, the receptacle may be displaced out of the housing. The receptacle may move along an arcuate path when the receptacle is moved between the stowed and deployed positions.
