A portable deodorizing apparatus having: a housing with first and second releasably joinable parts; and a deodorant source. The first housing part has a first connector and the second housing part has a second connector. The connectors are configured to be: a) engaged so as to thereby maintain the first and second housing parts in an operative relationship as an incident of relatively moving the first and second housing parts from a starting relationship into the operative relationship; and b) disengaged as an incident of relatively moving the first and second housing parts with the first and second housing parts in the operative relationship, so as to thereby allow the first and second housing parts to be changed from the operative relationship into the starting relationship. With the first and second housing parts in the operative relationship, the deodorant source is maintained in an operative position wherein deodorant is diffused into a space within which the deodorizing apparatus is placed.

An air enhancing device (1) for disseminating molecules and/or other substances into the air is disclosed comprising a base frame (5) configured to be fixedly mounted in a wall, panel, or furniture of a human accessible space, in particular in an in-wall box or an in-wall cavity in a wall of a building; a cartridge holder (7) attached to the base frame (5) and configured to receive a removable cartridge, the cartridge being designed to contain a fluid substance; and a fan and/or microblower configured to draw air into the air enhancing device (1) and expel air containing at least a portion of the substance out of the air enhancing device (1) into the human accessible space; and/or an emission module attached to the base frame (5) in fluid communication with the cartridge and configured to distribute a portion of the fluid substance into the air.

The present disclosure provides a perfume retaining structure, a method of manufacturing the perfume retaining structure, and a scent providing device that can reduce ventilation resistance of air that passes through a space in which a perfume retainer is arranged. The perfume retaining structure includes the perfume retainer, a retaining space in which the perfume retainer is arranged, and a first opening and a second opening that allow the retaining space to be opened to the outside. The retaining space has a ventilation area that faces the first opening and the second opening, and a retaining area that is arranged adjacent to the ventilation area and communicates with the ventilation area, and the perfume retainer is arranged in the retaining area.

A wearable aroma emitting device housing a refillable, removable atomizer spray bottle. The device comprising a circular tubular housing that can be impregnated with aromatic substance and emanate therefrom. An elastic band with an attached pocket is located within the chamber of the tubular housing. Alternatively, the tubular housing can be made of elasticized material. The pocket houses the atomizer spray bottle which can be filled with fragrance or scent. The pocket opening is covered with overlapping elasticized material attached to the tubular housing, which allows easy access to the atomizer spray bottle. The aroma device can be worn on the wrist; when the atomizer spray bottle is removed, it can be worn in the hair for scent. In another embodiment of the present invention, an ornamental three dimensional stuffed structure is located on a portion of the tubular housing. The atomizer spray bottle is housed within the stuffed structure.

An essential oil diffuser including multiple diffuser channels. Each diffuser channel includes an air pump and a cartridge assembly. The cartridge assemblies are removable receivable within a chassis assembly of the diffuser.

A fragrance dispenser can comprise a housing having a socket portion and defining a receptacle configured to receive a bottle having a fragrance-producing liquid therein and a wick extending therefrom. A heater can be disposed proximate to the receptacle so that, when the bottle is received within the receptacle, the heater is disposed proximate to the wick. A controller can be configured to deliver electrical voltage (e.g., pulse-width-modulated voltage) to the heater. A user input device can be in communication with the controller. The controller receives an input from the user input device that is indicative of a selected heat profile of a plurality of heat profiles, and the controller controls the power output of the heater in accordance with the selected heat profile.

An electronic scented candle is described that includes a movable flame-shaped component, a shell including an installation chamber, a fragrance container that is removably positioned inside the installation chamber and a scent chamber. An electric fan is positioned within the shell to drive the air into the scent chamber and a scent outlet coupled to the scent chamber to allow the fragrance material to leave the scent chamber and to reach an external environment of the electronic scented candle. The electronic candle also includes a receptacle for connecting a power cord on a bottom surface of the electronic candle. The bottom surface includes a plurality of protruding stands that provide a space to allow the power cord to be connected to the receptacle and be routed below the bottom surface.

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.
