A dispensing device for release of a volatile material includes a base, a drive arm coupled to a pendulum based drive mechanism, and a refill coupled to the drive arm. The refill includes a support base, at least one flange, a substrate coupled with the at least one flange, and a use-up cue.

A pump-fan assembly of an air modification device may include a fan, a pump and a disk. The fan may include a central hub disposed on a top surface of the disk, and a plurality of blades extending from the hub towards an outer circumferential edge of the disk. The pump may include a hollow pump body defining an inner tubular passage between an inlet end and a discharge end. An impeller may be arranged at the inlet end and an outlet port may be arranged at the discharge end. The pump and the fan may be coupled at an interface between the discharge end of the pump body and a bottom surface of the disk. The outlet port may be disposed in the interface and arranged to guide a stream of pumped liquid along the bottom surface of the disk. The disk may define a liquid barrier.

A photosensitizer formulation can be disposed on or in a container. The photosensitizer formulation, when in contact with molecular oxygen and activated by light or ultrasound, produces microbicidal singlet oxygen. A variety of different arrangements and applications are described. For example, an air flow device may also be included to generate a flow of air through or over the photosensitizer formulation.

The present invention relates to a disposable container (100). The disposable container (100) is use particularly for vaporization, evaporation or diffusion whereby filler materials of filler means are released into the air flow stream through air flow means. The disposable container (100) comprising filler means (101) filled with filler materials within the closed empty space between an inner side wall (101a) and an outer side wall (101b) and a top (101c) and a bottom part (101d) of the disposable container (100); and locking means (104) at the bottom part of the disposable container (100) to further secure the disposable container (100) to an air flow means. The inner side wall (101a), the outer side wall (101b), the top (101c) and the bottom part (101d) of the disposable container (100) are permeable or perforated enabling filler materials to be released into an air flow stream through air flow means; wherein filler materials are released by means of vaporization, evaporation or diffusion.

A deodorizing attachment for a fan includes a plate having an adhesive backing and a plurality of open-faced cups being disposed upon a face opposite the backing. Each cup has a mesh cover with each cup being configured to removably secure a unit of an air freshener.

A scent delivery assembly that includes a main body portion that defines an interior and includes at least one intake opening and at least one outlet opening, an airflow path that is defined between the intake opening and the outlet opening, a fan positioned along the airflow path, and at least a first cartridge positioned along the airflow path. The first cartridge includes a first cover that is movable between a closed position and an open position and a scent assembly. The scent assembly is not in flow communication with the airflow path when the first cover is in the closed position, and the scent assembly is in flow communication with the airflow path when the first cover is in the open position.

A fragrance dispensing apparatus includes a housing. The housing includes a platform configured to receive an ethylene vinyl acetate (EVA) bead packet. The EVA bead packet remains substantially unheated by the fragrance dispensing apparatus during operation of the fragrance dispensing apparatus. The fragrance dispensing apparatus further includes a lower module. The lower module includes a fan configured to selectively actuate airflow through the EVA bead packet.
