AI Technical Summary

Technical Problem

Existing fragrance systems for interiors fail to prevent fragrance emission in inactive states without requiring additional components or sensors, leading to unnecessary weight, cost, and potential maintenance issues.

Method used

A fragrance arrangement using airflow to move a closure element into an open position against a closing force in the active state and back into a closed position by gravity in the inactive state, utilizing textile or elastic plastic elements to control fragrance release.

Benefits of technology

This solution effectively prevents fragrance release in inactive states, reduces weight and cost, and extends fragrance lifespan by eliminating the need for additional elements, while ensuring reliable operation through gravity-assisted closure.

Abstract

Scenting arrangement (10) for an interior space (2), with at least one storage unit (12) having at least one outlet opening (16) for at least one fragrance substance (14), wherein a closing element (20) is associated with the at least one outlet opening (16), which is movable between an open position maximizing the effective cross-section of the corresponding outlet opening (16) and a closed position minimizing the effective cross-section of the corresponding outlet opening (16), wherein in an active state an airflow (LS) flows through the at least one outlet opening (16), which generates a flow force (F1) that moves the corresponding closing element (20) into the open position against a closing force (F2) and holds it in the open position,wherein in an inactive state no airflow (LS) flows through the at least one outlet opening (16) and the closing force (F2) moves the corresponding closing element (20) into the closed position and holds it in the closed position, wherein gravity acts as the closing force (F2) and the at least one closing element (20) is designed as a textile surface structure (20A) and / or as an elastic plastic element which is impermeable to the fragrance molecules emitted by the fragrance substance (14).
