The invention relates to a comfort management system (1), in particular for a motor vehicle, said system being designed to diffuse, into a passenger compartment, a volatile substance designed to neutralize or attenuate an existing olfactory perception that a person could have in this passenger compartment.

A benefit agent delivery system can deliver benefit agents on demand. The benefit agent delivery system comprises a first electrode layer, a microcell layer comprising a plurality of microcells, and a porous second electrode layer. Each of the plurality of microcells are filled with a liquid mixture comprising reverse micelles in a hydrophobic liquid that are formed from a polar liquid, a surfactant or stabilizing particles, and a benefit agent. Application of an electric field across a microcell layer causes an increase in the rate of release of the benefit agent of the microcell through the porous second electrode layer.

Disclosed are devices, systems and methods for air purification in an airflow tract of vacuum cleaners. In some aspects, an air purification system for a vacuum cleaner comprises an ultraviolet (UV) light unit disposed in a first location within the vacuum cleaner along an airflow pathway, configured to emit UV light at air containing particles including dust, dirt, and microbes while the air containing the particles is flowing in the airflow pathway where the UV light unit is disposed; and a particle filter unit disposed in a second location within the vacuum cleaner along the airflow pathway, the particle filter unit comprising one or both of a high-efficiency particulate air (HEPA) filter and an active carbon filter.

Fragrance dispensers with features that are capable of reducing wastage of fragrance, or of conserving fragrance, are disclosed. Such a fragrance dispenser may have a configuration that collects fragrance that is expelled from the fragrance dispenser, but has not vaporized or atomized sufficiently to dissipate into the environment, as well as fragrance that condenses immediately after it has been expelled from the fragrance dispenser. A spill-resistant bottle that may be used with a fragrance dispenser has a shape that orients an opening of the bottle in a somewhat upward orientation to prevent fragrance from spilling out when the bottle is tipped over. Fragrance dispensers with configurations that generate vortices to deliver fragrance into the surrounding environment are also disclosed.

An object of the present technology is to provide a technology that enables control of an odor. The present technology provides an odor presentation module including a first opening that first airflow containing an odor exits, and a second opening that second airflow exits, in which the first opening and the second opening are provided so that movement of the first airflow exiting the first opening is able to be controlled by the second airflow. The present technology also provides an odor presentation device and an odor presentation system including the odor presentation module. Further, the present technology provides an odor presentation method including a first airflow generation step of emitting first airflow containing an odor from a first opening, and a second airflow generation step of generating second airflow exiting a second opening or second airflow entering the second opening, in which movement of the first airflow exiting the first opening is controlled by the second airflow.

Described are modulating coatings that are configured to provide an improved release profile of a volatile composition from a base material, wherein the modulating coating includes a barrier substance that is configured to hinder a release of the volatile composition through the modulating coating, and a hygroscopic substance that is configured to facilitate the release of the volatile composition through the modulating coating.

To provide an aroma diffusing device and a method of controlling an aroma diffusing device that can enable a plurality of functions to be achieved by operation inputs to one operation input part.

Provided is an aroma diffusing device including: a perfume holding part in which a perfume is held; an air blowing source configured to supply air to the perfume holding part; an aroma discharge part through which the air having passed through the perfume holding part is discharged; an operation input part on which an operation input for the air blowing source is performed by a user; and an air blowing source control part configured to control a supply state of the air on the basis of an operation input on the one operation input part.

A bracket mounted on a car ventilation grille, in particular for fragrance carriers, consisting of a frame and fastening and stabilizing elements, characterized in that the frame is a U-shaped semi-closed structure provided with two arms, and the fastening and stabilizing elements are at least two sliding flexible fastening pads with a thickness less than or equal to the distance between the frame arms, at least one of which is applied to the first frame arm and at least one of which is applied to the second frame arm.
