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.

A fragrance bottle with a diffuser article for controlled release of fragrance product into an environment. The fragrance bottle uses an atomizing pump for spraying a liquid fragrance product onto a surface. The diffuser article is housed in an exterior section of the container. The diffuser article is able to effect a controlled release of aromatic molecules. The fragrance bottle can also be used to spray perfume onto the skin, in the usual way.

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 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 multi-layer article including a first non-active state and a second active state, the multi-layer article comprising an outer layer having a first side and a second side, an inner layer adjacent to at least a portion of the outer layer and including a volatile material, and an upper layer including a first side and a second side, the first side of the upper layer being adjacent to at least a portion of the inner layer. The multi-layer article is folded upon itself in the first non-active state so that at least a first portion of the second side of the upper layer is disposed on a top of a second portion of the second side of the upper layer, and the first portion and the second portion of the upper layer are heat sealed in the non-active state.

Provided are an aroma diffusing apparatus and an oil supply method. The aroma diffusing apparatus includes a main body and an oil storage tube. The main body is provided with a liquid storage chamber which is configured to store a liquid. The oil storage tube is configured to store an essential oil. When the aroma diffusing apparatus works, a bottom portion of the oil storage tube may be in fluidic communication with the liquid storage chamber thus allowing the essential oil in the oil storage tube to flow from the bottom of the oil storage tube into the liquid storage chamber as the liquid in the liquid storage chamber is being consumed.

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.

The present disclosure provides, in one embodiment, a filter device comprising a mouthpiece, a filter assembly in communication with the mouthpiece for filtering air exhaled into the mouthpiece, and an outlet check valve which permits air to be exhaled through the mouthpiece into the filter assembly, and substantially prohibits air from being inhaled from the filter assembly into the mouthpiece.

Disclosed is an air purification system (10) comprising an air purifier apparatus (50) for removing a pollutant from air, a sensor (21, 23) for sensing a concentration of the air pollutant and a scent release apparatus (40) responsive to a scent release signal, wherein the air purification system further comprises a processor (31) adapted to monitor the pollutant concentration from sensor data received from the sensor and to generate the scent release signal upon the monitored pollutant concentration falling below a defined threshold. Also disclosed is a method of generating a scented atmosphere in a room housing an air purification apparatus (50) for removing a pollutant from the air in the room.

A diffuser for multiple essential oils includes a housing that has at least one inlet and at least one outlet. At least two microblowers are carried by the housing to receive air though the at least one inlet. At least two bottles, each adapted to carry an essential oil, are associated with a corresponding one of the microblowers to generate a corresponding flow of oil-laden air. A controller selectively adjusts operation of each microblower to control the corresponding flows of oil-laden air to obtain a desired combination of oil-laden air exhausted through the at least one outlet.
