Electronic imitation candle devices are described that produce a scent while including a flame-like element that simulates a real fire flame. One example device includes a support assembly having a base, a top plate and a support rod that connects the base and the top plate, as well as a flame element and a light source to simulate a real candle flame. The device also includes a fragrance compartment above the top plate that includes a lid removably positioned on top of the fragrance container. The device is further provided with a heating element above the top plate and below the fragrance container to provide heat to the fragrance container, and a switch coupled to the lid of the fragrance container and operable to sense that the fragrance container is covered by the lid and to deactivate the heating element when the fragrance container is covered by the lid.

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 scent vaporizing and distribution device uses an electric heating element to rapidly vaporize a liquid scent material. An airflow generator is used to create a distribution airflow that distributes the vapor from the device. The airflow generator can be an electric-powered fan or a manually-powered pump or squeezable bladder. The liquid scent material can include a glycol or a water-glycol mixture. A scent material such as liquid or powdered deer urine or a pleasant scent that can be used as a room or automobile or room freshener is mixed with the liquid. The vapor generator can be removable and replaceable such that different scents can be used with a single airflow generator or an empty generator can be replaced.

Disclosed is an air purification system (10) comprising an air purifier apparatus (50) for removing a pollutant from air, a sensor (21, 23) for sensing a concentration of the air pollutant and a scent release apparatus (40) responsive to a scent release signal, wherein the air purification system further comprises a processor (31) adapted to monitor the pollutant concentration from sensor data received from the sensor and to generate the scent release signal upon the monitored pollutant concentration falling below a defined threshold. Also disclosed is a method of generating a scented atmosphere in a room housing an air purification apparatus (50) for removing a pollutant from the air in the room.

An air freshener is configured to be carried by a power outlet of an automobile. The air freshener includes a scent capsule disposed in a housing. A heat source is disposed in the housing adjacent and opposing a permeable membrane of the scent capsule. The heat source is configured to heat the fragrant material in the scent capsule and accelerate permeation of the fragrant material through the permeable membrane of the sent capsule. A hatch is pivotally coupled to the housing and substantially contained within a hatch cavity with an outer surface that is substantially flush with an exterior of the housing in a closed position, The hatch can include a capsule cavity therein. carrying the scent capsule, and facing an interior of the housing in the closed position.

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).

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.

Scented electronic candle devices are described that facilitate operation and usage of a variety of features such as light or scent or movement of the flame, or a combination thereof. The disclosed features also include multiple settings for the variety of features. For instance, the scent feature can be activated or deactivated by multiple switches, remote, sensors, timers, or similar devices. In addition, the intensity of the scent features can be increased or decreased by increasing or decreasing the amount of heat or air. Similarly the light feature can be activated, deactivated, or set on a timer. Additionally, the scented electronic candle devices can be equipped with rechargeable batteries that can be charged using a wireless charging station or by connecting the scented electronic candle device to an electrical wall outlet.

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.

A volatile composition dispenser and a method of dispensing a volatile composition is provided. The volatile composition dispenser includes a reservoir for containing a volatile composition and a transport member having a first end portion and an opposing second end portion, and an evaporative surface. The first end portion of the transport member is in fluid communication with the reservoir and the second end portion of the transport member is in fluid communication with the evaporative surface. The volatile composition dispenser also includes an air pump in gaseous communication with the reservoir.
