Abstract: This is a new system to aromatize spacious rooms, such as apartments, offices, factories, among other possible premises, such as shops, hotels or even large means of transport such as ships or ocean liners, all of which in many cases are likely to have central ventilation facilities. This new room aromatization concept results from the implementation of a scent dispensing device or apparatus comprising an electromechanical device or mechanism, that is automatic and programmable, and an aerosol container containing liquid that is either an aromatization product, sanitizer or the like, which is then sprayed onto the area where the device is located, as a result of the programmed automatic action of the device.
