Methods, systems, and devices relating to an electronic scented candle that is convenient to use and enables rapid generation and dissipation of scented materials are described. One electronic candle device includes a shell that has a through hole, a flame element protruding through the through hole, an installation lid including a locking base to allow removable coupling of a fragrance container, a scent chamber including a locking clip, a first channel, a second channel, a third channel, and a fourth channel. The scent chamber is removably coupled to the locking base by the locking clip, and an air pump provided to supply pressurized air.

A volatile material atomizing device comprises a housing having a fan, a fluid outlet, a plurality of air inlets and a plurality of air outlets. The plurality of air outlets are positioned at least partially around the fluid outlet. A fluid reservoir includes a wick and containing a volatile material. The fluid reservoir is disposed within the housing. An atomizing assembly is in fluid communication with the wick and positioned in the housing. The atomizing assembly is configured to dispense the volatile material out of the fluid outlet.

Embodiments of a controlled odor emission system and device include an odor presentation port tube and an odor tray securely retained against a platform, a valve housing securable to the platform adjacent the tray, a valve secured within the valve housing and an actuator for moving the valve. By controlling movement of the valve, precise amounts of an odor can be dispensed under programmatic control for training animals. Further, a system incorporating a central control unit and a reward dispenser in communication with an odor emission device to facilitate animal training.

A piezoelectric dispenser includes a refill having a container having a neck and defining a fluid reservoir, a wick holder affixed to the neck, and a wick retained by the wick holder that has an upper end that is in communication with a piezoelectric assembly, the wick defining a longitudinal axis. The dispenser further includes a housing having a base and an overhanging cover that defines a fluid outlet and extends inward from the base at a shoulder, toward the longitudinal axis, the overhanging cover being disposed around and above the upper end of the wick and housing the piezoelectric assembly. The piezoelectric assembly includes a coil compression spring and the base is provided on a rear side of the refill with the left, right, and front sides being exposed to a surrounding environment after the refill has been coupled with the overhanging cover.

Disclosed herein are aspects of portable vaporizers to deliver aliquots of heated air to material in a furnace. The furnace is multipurposed reducing heat loss, air leakage and delays in availability of air aliquots at the proper temperature for use. By dividing the furnace with an air permeable divider and placing material in the chamber a controller selectively providing electrical power to a heating element configured to heat air furnace. Upon application of suction to the fluid passage heated air passes through a divider which shapes the head of the heated plume before the aliquot of air reaches the material. A controller in signal communications with at least one temperature sensor controls the power flow to a heater to control the temperature produced by heating element(s).

Vapor generation and distribution devices, systems, and methods. An exemplary system of the present disclosure comprises a vapor generation system configured to volatilize or vaporize liquid chemical within a tank as volatilized or vaporized chemical, and a vapor distribution system configured to receive the volatilized or vaporized chemical from the vapor generation system and distribute the volatilized or vaporized chemical through a distribution conduit coupled to the second air flow generator.

The invention relates to an apparatus for vapour decontamination of an enclosed space. The apparatus comprises: (a) a reservoir comprising a supply of a liquid decontaminant; and (b) a vaporiser unit in fluid communication with the reservoir. The vaporiser unit comprises: a body that defines a lumen that passes along the length of the body, the lumen comprising a first end and a second end, wherein the first end receives liquid decontaminant from the reservoir; and a heating element that is configured to deliver sufficient thermal energy to effect rapid boiling of the liquid decontaminant within the lumen so that it exits the lumen via an exit port at the second end of the lumen as a vapour. The exit port is configured to deliver the vapour into a flow of a non-heated carrier gas, thereby facilitating distribution of the decontaminant vapour within the enclosed space. The invention also relates to a method for decontaminating surfaces within an enclosed space.

Provided is a release device including a housing having an inlet and an outlet, a heating element arranged in the housing, a first fan arranged to move air into the inlet and around the heating element, and a second fan arranged to move vapor out of the outlet. Other embodiments and arrangements are disclosed.

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.
