An air scenting assembly includes: a scent container which at least initially contains a scent perfume, and a scent perfume extracting mechanism, which is configured to release scent perfume from the scent container. The scent perfume extracting mechanism includes a scent perfume absorbing element insertable into said scent container, a scent carrying material, a dripping mechanism arranged onto said scent perfume absorbing element, said dripping mechanism is configured to deposit scent perfume from the scent container onto said scent carrying material, and a limiter to restrain extraction of scent perfume from the scent container, wherein the limiter comprises an air duct between the scent perfume absorbing element and the dripping mechanism, and the limiter is air flow controlled, wherein one end of said air duct is placed inside said scent container, and wherein the other end of said air duct is connected to a nozzle, said nozzle being arranged on said scent carrying material so that when said scent carrying material is drenched to saturation, no more air can pass through said scent carrying material and up into said nozzle and said air duct, and so that when the scent carrying material is dry enough passage of air through said air duct is allowed.

A heating and atomizing aroma diffuser includes a cover with an outlet thereof, an atomization core including a heating member and a liquid conduction member surrounding around the heating member, a spice storage, an airflow generator with an inlet thereof and a control unit. The inlet, the airflow generator, the spice storage, the atomization core and the outlet are connected to cooperatively form an air passageway thereof. The control unit is electrically connected to the heating member and the airflow generator to drive the heating member to generate heat, so that spice liquid adsorbed on a surface of the liquid conduction member is atomized into steam by high temperature, and then simultaneously drive the steam to diffuse into the air through the air passageway, thereby the steam can be diffused rapidly and sufficiently into the air, and has widespread spectrum and strong fragrance.

A essential oil diffuser that gasifies a liquid, such as water, which passes through a screen where it picks up essential oil and diffuses it into the ambient air.

Methods and systems are provided for improving the operation of a start/stop vehicle having an FEAD-driven AC compressor. During an engine idle-stop, fragrance is dispensed into a vehicle cabin via a fragrance dispensing device integrated with a vent of a vehicle AC unit. The dispensed fragrance masks must smells attributed to an evaporator when the engine is shut-down, thereby extending the duration of idle-stop.

An orientation independent delivery device including a replaceable cartridge that may be installed on a foundation. A cartridge includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.

A method and apparatus for vapor dispensing apparatus is described. The vapor dispensing apparatus includes: a housing defining a chamber having an inner contact surface, wherein the housing further comprises an aperture providing fluid communication between the chamber and an external environment; an evaporable material receptacle movably disposed within the chamber such that a dispensing portion of the receptacle is disposed in contact with at least a portion of the surface; and a motor coupled to the apparatus, configured to move the receptacle.

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.

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.

A system for releasing flavor comprises: a plurality of compartments adapted to receive a respective plurality of capsules, each capsule containing therein a flavor material; a dispenser system configured for dispensing into an environment a fluid obtained from at least one flavor material; and a controller configured for automatically selecting a dispensing protocol, for signaling the dispenser system to dispense fluids obtained from at least one flavor material contained in at least one capsule of the compartments, and for automatically re-executing the selecting and the signaling, according to a shuffle protocol.
