A dispenser capable of dispensing a fluid via a vertically-oriented piezo device comprises a reservoir in the form of a replaceable cartridge containing a fluid to be dispensed, a planar piezo element having front and rear surfaces and which in use is oriented with its plane vertical and which is drivable to vibrate and thereby dispense fluid from the front surface, and a pump to draw a predetermined amount, or dose, of fluid from the reservoir and to drive the dose of fluid at a predetermined above-atmospheric pressure to the rear surface of the piezo element for dispensing.

Includes an electromechanical device (1), which acts like an electronic catalog for the olfactory testing of different fragrances or aromas, contained in an absorbent cylindrical element (2) inserted into individual cartridges (3), which are interchangeable and encased in a carousel (4), supported on central bearings (5) and radially moved by means of an electric motor (6) with reducer (7) and gearing (8) that acts in a circular rack (9). Upon receiving a command, via application, the carousel (4) turns positioning the cartridge (3), corresponding to the fragrance or aroma chosen, in front of the connector nozzle (10), thanks to a positioning sensor (S), which counts the turns of the shaft of the electric motor (6). Next, a mechanical actuator (11) formed by an electric motor (12), gearing (13) that acts in a straight rack (14), which in turn drives a drawing cane (15), which pushes, and then retracts the cartridge, (3) inside the connector nozzle (10), and jointly with the air flow coming from a flexible hose (16), from where the air inflated by a compressor (17) enters said cartridge (3), forces the emission of the scent by the outlet orifice (18) of the top (19) of the box (20), thus providing the user a reliable olfactory testing.

The present invention is a system constructed and arranged to counteract bathroom sounds and scents including a housing, a speaker, microcomputer controller configured with input-output data mechanisms, a cartridge configured to store and expel a scent, a scent output, and a power source.

This system includes an olfactory display in which a plurality of aroma source cartridges can be loaded, a terminal device that controls the olfactory display, and a server connected to the terminal device via a network. The terminal device includes a content reproducer that reproduces an aroma-added content downloaded from the server. Aroma reproduction information includes aroma numbers standardized to specify types of aromas. The content reproducer determines which one of the plurality of aroma source cartridges loaded in the olfactory display is to be used to reproduce an aroma based on the aroma number, and allows the aroma to be emitted from the olfactory display based on the aroma reproduction information in synchronization with video and/or sound.

Methods, systems and devices associated with a scented electronic candle are described. In one example, an electronic candle includes an outer shell with one or more openings configured to allow a fragrance to exit to an ambient environment of the electronic candle. The outer shell comprises a central opening such that a flame element protrudes at least partially through the central opening. The device includes a light emitting component to emit a light onto the movable flame, and a mounting base positioned below the movable flame element. The device also includes a scent storage component removably coupled to the mounting base. The scent storage component includes a container to store a fragrance and an absorption member configured to draw the fragrance to the ambient environment of the electronic candle through the one or more small openings of the outer shell.

A device or system is provided that provides olfactory stimuli, and includes a piezoelectric vibration device that is used to produce scents corresponding to actions performed in a VR or AR environment, or other application. In some implementations, a user interacts with one or more game elements within a game program being executed by a game engine, and responsive to the interaction, the game engine may communicate a series of commands that cause a piezoelectric device of the device to generate scents to be experienced by the user.

A diffuser that may receive a refill bottle that supplies fragrance to the diffuser is provided. The diffuser includes a seat to facilitate easy placement and alignment of the refill bottle in the diffuser. The diffuser has an arm that can rotate about a pivot axis. The arm may rotate away from the seat to allow the user to place the refill bottle into the seat of the diffuser. The arm may also rotate towards the seat such that the arm can be placed over the refill bottle. The arm contains a piezo-electric component that can atomize the fragrance supplied by the refill bottle. The arm also includes a plurality of springs to create sufficient contact between the piezo and the refill bottle, to apply a downward force on the refill bottle, and to engage with a lock to secure the arm over the refill bottle.

An air freshener includes a first arm and a second arm connected together at one of their ends by a joint to enable swinging of the arms between an open configuration and a closed configuration. In a closed configuration, a fastener clasps opposite ends of the first arm and the second arm together to surround a central space in which a support structure, such as a support post of a rearview mirror on a vehicle, may be positioned. The first arm and the second arm each include an inner wall and lateral side walls defining an open chamber in which a fragrance substrate is retained by an interference fit. The inner wall defines an interior periphery, and ends of the lateral side walls define an exterior periphery of the air freshener.

Provided is a release device including a housing having an inlet and an outlet, a heating element arranged in the housing, a first fan arranged to move air into the inlet and around the heating element, and a second fan arranged to move vapor out of the outlet. Other embodiments and arrangements are disclosed.

A device including means for detecting a presence and/or a movement of a user in a toilet or room; means for storing a fragrance; means for storing a disinfectant; means for spraying the fragrance based on the movement of the user; means for spraying the disinfectant based on the movement of the user; means for controlling the spraying of at least one of said fragrance and said disinfectant; and means for remotely controlling the spraying of the fragrance or disinfectant.
