The two-part decorative diffuser cover forms a single decorative structure when both parts of the two-part decorative diffuser cover are joined together.

An ornament durably emitting a fragrance includes a shell with a sachet arranged therein, the sachet is made of a non-ventilating sealing bag and fragrant particles in the sealing bag; the bottom of the sealing bag is fixed in the shell, an easy-to-tear opening is arranged at the lateral side of the sealing bag, an upper side of the easy-to-tear opening is fixedly connected with a traction line, the other end of the traction line penetrates through a hole at the top of the shell, and the traction line extending out of the hole is fixedly connected with a pull ring. The ornament is internally provided with a sachet emitting the fragrance, in a production, transportation and selling process, the fragrance in the sachet cannot be dissipated, and when using the ornament, a consumer pull a traction line to open the sealed sachet to emit the fragrance in the sachet.

A face mask containing a network of conductive activated carbon meso-fibers crosslinked with a crosslinking agent bonded to a insulative polymeric micro-fiber based purification element. The purification element is captured between two ridged porous elements and contacted to the face by a biocompatible flexible polymeric seal. Optionally the front cover attaches to a main frame of the mask through a system of sliding locks that are coupled with bayonet latch mechanisms. The face mask attaches to the head of a wearer through a harness that couples with the sliding locks or alternatively with a biocompatible adhesive.

A wireless disinfection device, comprising a housing with a grip hole and a through hole. A spraying unit is fitted to the through hole. An air-intake motor, a liquid delivery tube, a nozzle unit and a liquid storage unit are disposed within the housing. A first tube end of the nozzle unit is connected to the spraying unit. A second tube end of the nozzle unit is connected to an air outlet tube of the air-intake motor. A third tube end of the nozzle unit is fitted downwardly to the liquid storage unit. The liquid delivery tube extends from the liquid storage unit and enters into the nozzle unit. The spraying unit includes a nozzle structure. After the air-intake motor is driven, the air can be blown into the nozzle unit such that each tube end of the nozzle unit generates an airflow pressure difference, thereby shooting an disinfecting liquid in the liquid storage unit to a first spray end of the nozzle structure located outside the nozzle orifice. Then, the high-pressure jet is directed to a second spray end of the nozzle structure outside the nozzle orifice such that the air and the disinfecting liquid are combined outside the nozzle orifice to achieve the spray disinfection.

Wall-mounted UV-C sanitizer light box has ultraviolet lamp elements and a cover or shade movable between operating positions. In a closed position in the lamp elements are covered. In an optional intermediate position the lamp elements can emit ultraviolet to the upper part of the room space above head level. In a full open position room surfaces and furniture in the room are exposed to germicidal irradiation. The unit is fully programmable as to mode of operation and duration. Sensors can shut the unit off if persons are present or motion is detected in the room space during sanitizing. An indicator light show the status of the arrangement, i.e., whether the most recent sanitization operation was completed successfully. The shade may have built-in louvers, wherein an upper room air sanitization operation can occur with the shade in the raised or closed condition.

A personal protective wearable air sterilizing apparatus is comprised of a series of looped internal conduits, designed in such a way to allow total internal reflection of UV light, and the simultaneous sterilization of atmospheric air. The apparatus has oxygen generator using electrolysis of water and neutralizes hydrogen gas derived from the process to an inert compound such as hydrogen peroxide; or reuses the hydrogen to generate electricity.

An air treatment system includes an enclosure, a first UV lamp, a second UV lamp, and one or more air driving components. The enclosure includes an inlet, an outlet, and a passageway between the inlet and the outlet. The one or more air driving components are configured to draw air into the enclosure via the inlet, and to direct air toward the outlet via the passageway. The first UV lamp is configured to output first UV light having a first peak wavelength, and the second UV lamp is configured to output second UV light having a second peak wavelength that is different from the first peak wavelength. The first and second UV lamps are disposed in the enclosure, and each of the first light and the second light irradiates the passageway. A method of operating the air treatment system is also disclosed.

A scent vaporizing and distribution device uses an electric heating element to rapidly vaporize a liquid scent material. An airflow generator is used to create a distribution airflow that distributes the vapor from the device. The airflow generator can be an electric-powered fan or a manually-powered pump or squeezable bladder. The liquid scent material can include a glycol or a water-glycol mixture. A scent material such as liquid or powdered deer urine or a pleasant scent that can be used as a room or automobile or room freshener is mixed with the liquid. The vapor generator can be removable and replaceable such that different scents can be used with a single airflow generator or an empty generator can be replaced.

The volatile substance evaporation device comprises a casing (1) provided with an evaporation surface (2), said casing (1) housing inside it a substrate (3) impregnated with said volatile substances, wherein said substrate (3) is a sheet which preferably comprises a plurality of grooves. It allows the device to have a similar diffusion value for a specific air flow and for a considerable internal temperature of the vehicle, thus ensuring continuous evaporation.

A scent device comprises a container defining a volume and configured to hold a fill material, which may include one or more chemical compounds, natural formulations, or both configured to absorb odor and/or moisture, and/or emit a scent. The scent device includes a vented cap reversibly coupled to the container via a connection mechanism, and a breathable insert sandwiched between the container and the cap. The breathable insert may comprise a non-woven fabric supported along its perimeter by a structural mount. Methods of manufacturing the scent device involve cutting a mount from a support material, attaching a breathable material to the mount to form a breathable insert, depositing a scent-controlling material within a container, and sandwiching the breathable insert between the container and a cap upon coupling the cap with the container.
