An aroma diffuser device for diffusing selected scents into the airspace of interior habitable spaces is disclosed. The disclosed device includes multiple diffusers for diffusing multiple scents into a fan-induced airstream. Two, three or more diffusers can be included in and/or upon the device.

An excimer bulb assembly including an excimer bulb and a pass filter such that the excimer bulb assembly does not emit substantial UV radiation in wavelengths longer than 231 nm, 232 nm, 233 nm, 234 nm or 235 nm. The wavelengths are measured at an incident angle of zero (0) degrees to the filter plane. The pass filter is preferably constructed of a plurality of layers of hafnium oxide, and most preferably constructed of less than seventy five (75)layers of hafnium oxide. The excimer bulb, pass filter, and two electrical connectors may be adapted to form a cartridge which may be adapted to swivel along its main axis. The cartridge may further include a smart chip. The smart chip may retain and store information regarding the assembly and preferably retains hours of use of the excimer bulb.

A method and a system for generating a fragrance (also referred to herein as perfume) are disclosed. A method may comprise providing a perfume blender machine (100) and cartridges (102) for storing liquid olfactory ingredients (112), the machine comprising dispensing means to dispense olfactory ingredients (112) from the cartridges (102) for generating a fragrance (114); controlling the dispensing means to generate a fragrance (114) based on instructions given by a user on the liquid olfactory ingredients (112) to be blended and the quantity of each; and generating a recipe with the information of the ingredients (112) and their respective quantities which have been used to generate the fragrance.

A surface cleaning device includes a nozzle and an odor dial assembly. The nozzle includes a nozzle housing and a dirty air passageway. The odor dial assembly include a fragrance member and a dial body configured to be removably coupled to the nozzle housing. The dial body at least partially defines a fragrance cavity configured to at least partially receive the fragrance member and a fragrance passageway extending therethrough. The odor dial assembly is configured to transition between a plurality of user-selectable positions to adjust an amount of fragrance particles released by the fragrance member into the dirty air passageway.

A type of fragrant eyeglasses is revealed. The fragrant eyeglasses include an eyeglass body and a nose bridge which is arranged at the eyeglass body and provided with a mounting space for mounting fragrance tablets. At least one air inlet and at least one air outlet for guiding air flows are disposed on a front side and a rear side of the mounting space respectively. Thereby the fragrance tablet mounted in the nose bridge is just adjacent to the user's nose when the eyeglasses are fitted on bridge of user's nose by the nose bridge. Thus the user smells scents emanated from the fragrance tablet and feels refreshing and soothing. The air inlet and the air outlet not only help emanation of scents from the fragrance tablet, but also guide the scents to spread along with air flows induced by movements of people who while walking or riding bicycles.

A volatile composition dispenser including a container having a bottom wall and side walls extending circumferentially around the bottom wall to define a reservoir and a perfume composition contained in the container. The side walls have a circumferential inner edge defining a reservoir opening. A reservoir opening plane extends across the reservoir opening and intersects the circumferential inner edge. There is a first depth and a second depth between the bottom wall and the reservoir opening plane, wherein D1 is longer than D2.

A tool adapted for use with a diffuser cartridge and a fluid container, wherein the tool is adapted to facilitate insertion and removal of the diffuser cartridge to and from the fluid container. The diffuser cartridge contains mineral agent beads or other materials which can enhance the quality of fluid contained within the container.

Aspects of the present disclosure include a method of managing scent in an environment, which includes disposing at least one scent diffusion device within an environment, wherein the at least one scent diffusion device comprises a communications facility that enables transmitting signals to and receiving signals from a remote computer, receiving at least one target value of a scent parameter for the environment at the remote computer, and controlling, via the remote computer, diffusion of a liquid from a source of the liquid in fluid communication with the at least one scent diffusion device to achieve the target value of the scent parameter. Controlling a diffusion rate of the liquid includes altering at least one of a voltage and a duty cycle applied to at least one component of the diffusion device.

Methods, systems, and devices are disclosed for implementing switchable dispensing and/or delivery of scented substances. In one aspect, a device includes a cartridge structured to include one or more chambers containing one or more scented substances contained in a corresponding chamber, a housing structured to include a compartment to hold the cartridge, an opening to allow the scented sub stances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to accelerate a scented substance from the corresponding chamber to the opening, and an actuator switch arranged in a corresponding transporting channel and operable to move between an open position and a closed position based on an applied signal to selectively allow passage of the scented substance from the corresponding transporting path.

Various fragrance dispensers are disclosed. The fragrance dispenser can include a core unit that has a connection unit and a control unit. The fragrance dispenser can include a cartridge that is configured to engage with the core unit. The cartridge can include an impeller and a fragrant material. The fragrance dispenser can have a motor that drives the impeller, thereby dispersing the fragrance. The cartridge can be configured to disengage from the connection unit, such as when the cartridge reaches a depleted state.
