The refill can be used with different devices for evaporating volatile substances by using one of said coupling means, depending on the means provided in the device.

An electro-ionic device configured for being worn on the face of a person is disclosed. The electro-ionic device includes at least two electrical conductors spaced apart from each other defining at least a portion of a respiratory pathway therebetween and a circuit configured to apply a first voltage between the two conductors during inspiration and a second voltage greater than the first voltage during expiration.

A vehicle-mounted intelligent fragrance generator includes a casing and a plurality of essence boxes. The casing includes a base. Each essence box includes an outer sleeve, an inner sleeve, an essence block and a fragrance front cover, the outer sleeve has a protrusion, and the protrusion is disposed at a front end portion of an inner wall of the outer sleeve. A rear end of the inner sleeve is a closed end, a front end is an open end, and the front end of an outer wall of the inner sleeve is provided with an anti-rotation strip. The outer sleeve is fixed inside the base, the outer sleeve, the inner sleeve and the essence block are sequentially sleeved, the front end of the inner sleeve protrudes from the outer sleeve and extends out of the base, and the anti-rotation strip is clamped on the protrusion of the outer sleeve.

A scent dispensing system comprises a plurality of storage tanks containing a liquid medium of terpenes, scent agents, and/or flavoring agents, and one or more dispensing devices that are adapted to deliver atomized liquid medium from the plurality of storage tanks to produce a scent selection for a user.

A sterilization and disinfection device includes a housing. A control board, a humidification water tank, a humidification water trough, an ultrasonic humidifier and an ozone water tank are provided inside the housing. The humidification water trough communicates with a humidification outlet through a humidification pipe. A humidification air input channel is connected to a humidification fan connected to a humidification air inlet. The ozone water tank is equipped with an electrolytic ozone generator. The ozone water tank communicates with an ozone gas outlet through an ozone gas output pipe and a mixing chamber. The ozone water tank communicates with a water filling port through a water filling pipe. An ozone fan is installed in an ozone air inlet. The control board is electrically connected to the button display panel, the ultrasonic humidifier, the electrolytic ozone generator, the ozone fan, the humidification fan and the power inlet, respectively.

A photosensitizer formulation can be disposed on or in a mesh; net; netting; screen; curtain of strands, fibers, or monofilaments; substrate, personal protective gear, mask, or any other suitable object. 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. A fluorescent formulation may be included to monitor photobleaching. The photosensitizer formulation may be disposed in a concentration gradient to generate antigenic particles by damaging or destroying microbes.

Disclosed are devices, systems and methods for controlling scent delivery by a scented article for beverage containers. In some aspects, a scent delivery system includes a cap attachable to a beverage container; and a scented article that couples to the cap, wherein the cap comprises a base, a movable component coupled to the base and able to move between a first position and a second position, and a scent chamber including an encasement to which the scented article is attached, the encasement coupled to the movable component or the base, wherein a portion of the scented article is exposed to air from an outside environment with respect to the cap when the movable component is in the second position, and wherein the encasement creates a contact seal to enclose the scented article within the scent chamber and lock in the scent when the movable component is in the first position.

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.
