A rotary aromatherapy lamp structure includes an aromatherapy lamp and rotating cover. Abase of the aromatherapy lamp is configured with a control circuit board in electric connection with a fan and heating element and first support, a part of the first support positioned relatively above the fan and heating element is in combination with a container, and the first support above the container is extended with a fulcrum; the rotating cover is covered on the fan, heating element and first support, and the fulcrum is used to prop against an axle center of the fan leaves, allowing a space to be formed between the rotating cover and base and thus allowing the rotating cover to have a rotation mechanism. Whereby, the heating element heats the container to speed the essential oil evaporation, and air flow generated from the fan blows the fan leaves to rotate the rotating cover.

The candle lamp with a 3D swinging flame and an aroma not only plays a role of lighting and creating an atmosphere, but also has an aroma function for purifying air and making people relaxed. The invention is simple in installation structure, easy to implement, low in cost and convenient in popularization.

A water-based fragrance composition comprises at least about 67 wt % water and between about 5 and about 17 wt % of a first organic solvent, wherein the first organic solvent comprises one or more relatively volatile, water soluble, low molecular weight organic compound(s) having a boiling point less than about 100 C. The water-based fragrance composition further comprises about 5 wt % or less of at least one fragrance formulation and between about 0 and about 22 wt % of a second organic solvent, wherein the second organic solvent comprises one or more moderately volatile, water soluble organic compound(s) having a boiling point greater than or equal to about 100 C. and less than or equal to about 300 C.

A diffuser includes a base, a fan mounted to the base, a receptacle provided over the fan and mounted to the base, a sleeve mounted on the upper surface of the base and enclosing the fan and receptacle, and a lid mounted over the sleeve. Each of the base and the lid comprises at least one opening formed about a periphery thereof. The receptacle comprises a bottom wall with a plurality of opening formed therethrough and a vertically extending sidewall to retain a fragrant medium therein. The fan forces airflow from an exterior of the diffuser, into the base through the at least one opening, through the plurality of openings formed in the bottom wall of the receptacle, through the receptacle and about any fragrant medium therein, into a volume of space above the receptacle enclosed by the lid, and out through the at least one opening in the lid.

The invention provides an air treatment device (100) configured to deactivate one or more of bacteria and viruses from air, the device (100) comprising a deactivating material (121) comprising for at least 80 wt. % of one or more of a terpene and a terpenoid having no aliphatic unsaturated bond, the air treatment device (100) further comprising a gas flow generation device (130), wherein the air treatment device (100) is configured to provide said deactivating material (121) into a space with an emission rate (S) of at maximum 250 mg/h from a release area (1112).

A scent air purifier contains a body, a fan, a filter element, a holder, a circuit control unit, a case removable from the body. The body includes an accommodation chamber, a receiving groove, and a first vent. The accommodation chamber is defined in the body, the receiving groove is located above the accommodation chamber, and the first vent communicates with the accommodation chamber and the receiving groove. The fan is accommodated in the accommodation chamber. The filter element is connected below the accommodation chamber and communicates with air from an external environment outside the body so that the fan delivers the air to flow through the first vent and the receiving groove, after drawing the air from the external environment. The holder is connected with the body, and the circuit control unit is housed in the holder and is electrically connected with a power source and the fan.

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.

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 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.
