A fragrance dispensing system for an aircraft that includes a fuselage defining a cabin interior and an environmental control system (ECS). The ECS includes a source of air that moves air between the source of air and the cabin interior along an airflow path, a mixer unit in airflow communication with the source of air and positioned downstream from the source of air in the airflow path, at least a first air duct positioned in the airflow path between the mixer unit and the cabin interior, and a fragrance dispensing unit positioned between the air source and the cabin interior along the airflow path. The fragrance dispensing unit is configured to dispense at least a first fragrance into the airflow path.

A humidifying device for a vehicle has a humidity detection part, a blower, a non-water-supply humidifier, and a controller. The humidity detection part detects a humidity in a vehicle compartment. The blower draws, as an intake air, an inside air in the vehicle compartment and an outside air outside the vehicle compartment at a specified ratio and blows the intake air toward the vehicle compartment. The non-water-supply humidifier collects water included in the inside air and supplies a humidified air, which is humidified using the water, toward a specified area in the vehicle compartment. The controller sets the specified ratio between the inside air and the outside air and controls an operation of the non-water-supply humidifier. The controller controls the blower to draw at least the inside air, when the non-water-supply humidifier is operated, and when a humidity in the vehicle compartment is lower than a specified humidity.

A scent diffuser (e.g., air freshener) configured to automatically circulate fragrant air throughout a surrounding environment comprises a powered air circulator configured for circulating air and a fragrance composition throughout the surrounding environment, and a solar cell positioned within a support face of the air circulator. The support face is configured to secure the scent diffuser relative to a support surface and has an open portion configured to allow light to contact the solar cell. The air circulator may comprise a centrifugal fan positioned within the housing and configured to draw air through intake apertures in sidewalls of the housing and to exhaust air and fragrance through an outflow aperture of the housing.

A volatile material dispenser includes a housing configured to receive a refill containing a volatile material and a wick. The housing includes a heater arrangement that defines an opening in which a distal portion of the wick is received. Additionally, a top cover is configured to be coupled to the housing and defines a central aperture through which a vapor plume exits the housing. The top cover includes an annular wall having a first surface, a second surface opposite therefrom, an outer edge, and an inner edge that defines the central aperture. The central aperture is positioned about a longitudinal axis that defines opposing first and second axial directions. The top cover further comprises a plurality of apertures arranged around the central aperture. The top cover defines a converging outlet defined between a trough and the inner edge, and the second surface curves from the trough to the inner edge.

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.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes an intake flow passage suctioning external air, a discharge flow passage discharging internal air, a blower unit flowing air flowing to the intake flow passage to the discharge flow passage, a discharge humidification medium disposed on the discharge flow passage to additionally humidify flowing air, a water tank humidification medium disposed between the blower unit and the discharge humidification medium to humidify flowing air, and a watering unit spraying water between the water tank humidification medium and the discharge humidification medium.

Provided is a humidification and air cleaning apparatus including a water tank storing water; an air wash inlet formed at the water tank and communicating the inside and the outside of the water tank and a water tank humidification medium formed of a material for absorbing water and providing humidification on air passing through the air wash inlet. The water tank humidification medium is located inside the air wash inlet to cover the air wash inlet.

Provided is a humidification and air cleaning apparatus. The humidification and cleaning apparatus includes: a water tank storing water; an air wash inlet disposed in the water tank and communicating the inside of the water tank with the outside thereof; a water tank humidification medium covering the air wash inlet, formed of a material absorbing water, and humidifying air passing the air wash inlet; a watering housing disposed inside the water tank, suctioning water of the water tank thereinto, pumping the suctioned water to an upper side when rotating, and spraying the pumped water; and a watering motor providing a torque to the watering housing. Here, the water tank humidification medium is spaced from water stored in the water tank and is wetted by water sprayed from the watering unit.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes a water tank storing water, a visual body forming at least a portion of the water tank and formed of a transparent material, a water tank inlet formed at the water tank and communicating the inner and outer sides of the water tank, a water tank humidification medium covering the water tank inlet, formed of a water absorbing material, and providing humidification on air passing through the water tank inlet, a watering housing disposed inside the water tank, drawing water of the water tank into the inside, pumping the drawn water upwardly when rotating, and spraying the pumped water, a watering motor providing a torque to the watering housing, a lower nozzle disposed at the watering housing and spraying the pumped water to the water tank humidification medium, and a upper nozzle disposed at the watering housing and spraying the pumped water to the visual body.
