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.

A self-sealing fragrance dispenser can be positioned within an air channel having active and inactive air flow states. The dispenser can include a main body having an cavity in which a fragrance medium can be disposed, an access door, an intake door, and an exhaust door. The intake and exhaust doors can be biased in closed positions via bias structures or gravity. Pressures exerted against the intake and exhaust doors when the air channel is in the active air flow state place the intake and exhaust doors in respective closed intake and closed exhaust door states that seal the amount of fragrance medium within the cavity when the air channel is in the inactive air flow state.

An essential oil reflux-type atomizer comprising the following structures: chassis, housing, atomization chamber, gas pump, gas tube, gas nozzle, oil nozzle, and filter atomization mechanism. The filter atomization mechanism is installed in the housing and has an upper filter and a lower filter. The essential oil atomizer can be improved efficiency and reduced noise level.

Vapor generation and distribution devices, systems, and methods. An exemplary system of the present disclosure comprises a vapor generation system configured to volatilize or vaporize liquid chemical within a tank as volatilized or vaporized chemical, and a vapor distribution system configured to receive the volatilized or vaporized chemical from the vapor generation system and distribute the volatilized or vaporized chemical through a distribution conduit coupled to the second air flow generator.

The present invention relates to a perfume dispensing device, the device being electronically controlled and the actuation of perfume spraying being performed via an actuator (12) located on or under a device housing (1). All components of the device are located on or in the housing (1), wherein the housing also accommodates a control circuit (10) for controlling the device, which may optionally include a system (13) for wireless communication with a smart device (14) having a dedicated application uploaded, through which the user sets the desired parameters. The device may include several storage containers (2), which allows the user to select the desired perfume or to personalise the perfume via a dedicated application. The actuator is actuated by pressing or touching the actuator (12) or via an external device.

A modular air treatment unit for an over the road vehicle is independent of an associated climate control system. The air treatment unit is configured to filter and sanitize air within the passenger compartment as air moves along a flow path separate from a flow path through the climate control system. The modular air treatment unit includes a housing defining a circuitous passageway, an air filter mounted to the housing, a fan configured to move air along passageway, and an ultraviolet light source arranged in the housing. The ultraviolet light source is configured to discharge germicidal ultraviolet light inside the housing to eliminate pathogens in the housing.

Identification and elimination of micro-organisms in the air, on surfaces and on objects that are stationary or in motion using artificial intelligence and machine learning algorithms.
