Provided is a coronavirus-killing and scalp care device using a carbon heating mat. Carbon heating mats are applied to a coronavirus-killing face cover and a scalp cover which are coupled to or separated from each other as necessary, and a filter part for accommodating a scent material is formed around a nose and mouth portion of the coronavirus-killing face cover. Therefore, a temperature of the scalp is raised to boost immunity, prevent hair loss, and the like, heat is introduced into the human body during breathing through the nose and mouth to kill various disease-causing pathogens (particularly, coronaviruses) in the human body, and a scent material filling the filter part is fumigated by heat generated by the carbon heating mats and introduced into the human body through breathing to prevent and cure diseases.

The present invention discloses a novel multipurpose fast dehumidification device, in which materials with different functions can be placed simultaneously or separately, such as moisture absorption materials, aromatic materials, mosquito repelling (insect repelling) materials or deodorization materials. The present invention comprises a base, a placement frame and a circulation mechanism One end of the placement frame is movably connected with the base, and the other end of the placement frame is movably connected with the circulation mechanism; and the moisture absorption materials are placed in the placement frame. After the device is started, air in an environment is sucked by the circulation mechanism, then reaches the placement frame, and then is discharged from the placement frame after being dehumidified. The present invention has the beneficial effects that the structure is simple, and the use is convenient; the complicated structure of a traditional dehumidifier is abandoned, and the cost of a product is reduced to a maximum degree; at the same time, a single dehumidification function is expanded, which can play a role in different use scenes. That is, besides the dehumidification function, functions of atmosphere creation, mosquito repelling (insect repelling), deodorization and the like can also be realized.

A benefit agent delivery system can deliver benefit agents on demand. The benefit agent delivery system comprises a first electrode layer, a microcell layer comprising a plurality of microcells, and a porous second electrode layer. Each microcell of the plurality of microcells are filled with a liquid mixture comprising reverse micelles in a hydrophobic liquid that are formed from a polar liquid, an ionic surfactant, and a benefit agent. Application of an electric field on the microcell layer affects the rate of release of the benefit agent through the porous second electrode layer.

An air filtering and treatment apparatus (10), the apparatus (10) including: a housing (12) having an air inlet (14), an air outlet (16), an air passageway (24) between the inlet (14) and outlet (16), and a fan (18) arranged to urge air through the air passageway (24) between the air inlet (14) and the air outlet (16), wherein the housing (12) includes filter (20) arranged to filter air passing through the air passageway (24), and a receptacle (26) located toward the air outlet (16) relative to filter (20). The receptacle (26) is adapted to hold treatment composition (22) such that an evaporable vapour associated with the treatment composition (22) is able to accumulate in a headspace (41) of the receptacle (26), the headspace (41) including at least one aperture (36). The air passageway (24) may be shaped such that air flows substantially perpendicularly past the at least one aperture (36) of the receptacle (26) such that a pre-determined amount of the evaporable vapour is entrained into the filtered air released from the air outlet (16). A system (100) and method are also disclosed.

An odor control system for landfills includes a vapor device configured to generate an odor neutralizing chemical mixture, and at least one fan directed at a working face of a landfill. The at least one fan includes a fan housing having an inlet opening and a discharge opening connected by a passageway therethrough, a blade assembly positioned within the passageway of the fan housing and configured to rotate to generate an airflow from the discharge opening in a first direction, and a motor coupled to the blade assembly. The system includes at least one nozzle in fluid communication with the vapor device and proximate the discharge opening. The at least one nozzle is configured to disperse an odor neutralizing chemical vapor in the same first direction of the airflow from the discharge opening.

In various embodiments, methods of treating a space to reduce a concentration of volatile organic compounds present in the space using chlorine dioxide are provided. A method can include application of aqueous and gaseous chlorine dioxide solutions within the space or to materials located within the space. Treatment of materials that emit volatile organic compounds with chlorine dioxide can reduce the emission rate or shorten the volatile organic compound emission cycle of the material. Soft surface substrates such as carpeting materials can be treated with chlorine dioxide to reduce volatile organic compound emission and/or to reduce the number of microorganisms present in the material.

The device for the diffusion of volatile substances comprises a container (1), which holds a liquid with the volatile substances in it, and which has an opening (9), for communication from the inside of the housing (6) to the outside; a cover (2) which can be attached to the container (1) to close the opening (9), a diffusion wick (4) for the controlled diffusion of the volatile substances, one end (13) of which protrudes from the cover (2); and a cap (5) which covers the end (13) of the diffusion wick (4) which protrudes from the cover (2), the container (1), the cover (2), the diffusion wick (4) and the cap (5) being made of the same plastic material. It thus makes it possible to provide more efficient recyclability in accordance with currently existing methods.

The present invention solves the problem of efficiently disinfecting and deodorizing indoor areas with ozone, without introducing health risks to people inside these areas. A cold plasma ozone generator generates ozone that is distributed to one or more rooms where disinfection and/or deodorization is needed. The distribution of ozone is regulated by valves controlled by a main control module collecting data from ozone concentration and IR motion detectors installed at rooms where the ozone is distributed, and other sensors in the ozone generator, and by using a schedule associating information derived from the sensory data, with dates, time slots, and desired ozone concentrations. If ozone concentrations exceed predefined levels, ozone generation and/or distribution is interrupted. When malfunctions occur, either the main control module commands the system to enter in emergency shutdown or lockdown, or a local control module or the ozone generator take control of the ozone generation and distribution.

The present invention relates to a composition comprising at least one fragrance ingredient, one or more solvents and water, a method for obtaining such a composition in the form of a homogeneous composition, and to the use of such a composition to release a fragrance in an atmosphere in a controlled way.
