A perfume composition having controlled release of phytoncides in an atmosphere in order to generate an air condition resembling the air environment of a forest is provided. The perfume composition includes a) at least about 0.6% by weight of at least one phytoncide; and b) a perfume mixture including (i) at least one solvent; and (ii) at least one fragrance ingredient. At least about 25% by weight of the at least one phytoncide is selected from the group consisting of pinene alpha, pinene beta and combinations thereof.

A space cleaning system includes: a detection unit configured to detect generation and a generation position of an infectious substance in a space; an airflow control unit configured to generate an airflow towards the generation position detected in response to detection of the generation of the infectious substance; and a cleaning control unit configured to clean the space at least after the generation of the infectious substance is detected.

A device for selectively providing an odor-rich environment includes a housing and a cover. The housing includes a central cavity and a plurality of chambers configured to store a predefined fragrance therein and having a respective outlet formed on an outer wall of the housing. The cover includes an exterior surface having at least one vent formed on the exterior surface. The exterior surface includes an interior sidewall and an exterior sidewall forming an inner chamber that slidably engages the housing such that the cover is configured to move between an open position and a closed position. Responsive to the cover being in the open position, the at least one vent is generally adjacent to the outlet of at least one of the plurality of chambers of the housing. The odor-rich environment can assist in preventing and/or treating postoperative delirium (POD) postoperative cognitive dysfunction (POCD), and/or pain in a subject.

Provided is a method for providing a fragrance blend customized for an individual. Also provided is a method of enhancing a scent in a fragrance. Also provided are fragrance blends customized for the individual or having an enhanced scent.

A liquid atomization device includes: an inlet; an outlet; and a liquid atomization chamber. The liquid atomization chamber is provided in an air passage between the inlet and the outlet. The liquid atomization chamber includes a rotary shaft, a pumping pipe, a collision wall, a reservoir, and a drain port. The rotary shaft is rotated by a rotary motor and is disposed in the vertical direction. The pumping pipe includes a lower portion having a pumping port and an upper portion fixed to the rotary shaft, and is rotated in coordination with rotation of the rotary shaft to pump up water through the pumping port and centrifugally discharge the water. The pumping pipe generates, inside the pumping pipe, a whirlpool in the water in the reservoir by the rotation, and forms, at the center of the whirlpool, a void providing communication between the pumping port and the drain port.

A wearable system for dispensing a substance is disclosed. The wearable system includes a base element, at least one reservoir surface defining a reservoir disposed in the base element, at least one first opening disposed along on an outward facing portion of the base element and providing fluid communication with the reservoir, and a rolling element disposed in the at least one first opening such that a first portion of the rolling element is outside the base element and a second portion of the rolling element is inside the base element.

A fragrance compound impregnated porous carrier enclosed within an envelope where a tear initiating feature of the envelope is aligned with a trimmed portion of the porous carrier, to thereby prevent a tear in the envelope from inducing a tear in the porous carrier.

An apparatus includes multiple first reservoirs and multiple second reservoirs joined with a substrate. Selected ones of the multiple first reservoirs include a reducing agent, and first reservoir surfaces of selected ones of the multiple first reservoirs are proximate to a first substrate surface. Selected ones of the multiple second reservoirs include an oxidizing agent, and second reservoir surfaces of selected ones of the multiple second reservoirs are proximate to the first substrate surface.

An air purifier and a purifying method are provided. The air purifier includes a housing, a sterilization and ozone-generating unit, a physical filter, a first ozone-removing unit, and a cover. The housing has a sidewall and a bottom surface to define a processing space, wherein an upper end of the housing has an air inlet and the sidewall has an air outlet. The sterilization and ozone-generating unit is disposed in the processing space. The physical filter is disposed in the processing space, extends along the sidewall, and surrounds the sterilization and ozone-generating unit. The first ozone-removing unit is disposed between the physical filter and the sidewall. The cover is openably disposed at the air inlet.

A display container for displaying an aromatic botanical specimen includes: (a) a container body for enclosing the botanical specimen and scented air having a scent of the botanical specimen; (b) at least one scent discharge port in the container body; and (c) an air pump coupled to the container body and operable to discharge the scented air from within the container body to the environment through the scent discharge port.
