A torchiere style sanitizing device for disinfecting airborne pathogens while providing aesthetic area lighting. A reversible fan exchanges air between the upper room air plume and the lower air plume by passing the air through a center disinfecting section. The disinfection section may include a linear UV-C light, reflective tube, and light trap positioned at one or both ends of the disinfection section to maximize the exposure of the air to the UV-C light and contain the UV-C light within the device. The device includes a conventional illumination source in an upper shade and can selectively provide one of more of room air flow, room air disinfection, and room illumination.

A diffuser having a plurality of atomizers associated with a single pump is provided. The diffuser may include four or more atomizers that may be removably coupled to the diffuser. Each atomizer may store the same or different oils. In some embodiments, the outlet of the atomizer may have a tortuous passageway to prevent diffusion of large oil droplets. The diffuser includes a plurality of valves associated with the plurality of atomizers, such that the valves may be selectively actuated to permit flow to the selected atomizers.

A device including means for detecting a presence and/or a movement of a user in a toilet or room; means for storing a fragrance; means for storing a disinfectant; means for spraying the fragrance based on the movement of the user; means for spraying the disinfectant based on the movement of the user; means for controlling the spraying of at least one of said fragrance and said disinfectant; and means for remotely controlling the spraying of the fragrance or disinfectant.

An apparatus and method for inactivation of airborne pathogens to include a reactor space with an intake opening, an exhaust opening, and an airflow path disposed between the intake and exhaust openings for air to continuously transit throughout the reactor space. The apparatus also includes at least one of (i) a corona discharge unit with a pressure swing adsorption unit, or (ii) a UV-C germicidal lamp to generate a sufficient concentration of ozone and UV light to inactive pathogens. The apparatus also includes a catalyst disposed within the path of the airflow to convert ozone to oxygen following the inactivation step and an adsorbent to remove nitrogen oxides from the air. The apparatus also includes sensors for measuring ozone and nitrogen oxides concentrations at the exhaust opening.

The invention disclosed herein relates to an odor control system including features to allow a media scrubber to function to treat a humid, or saturated, or superheated exhaust stream. In some embodiments, the system disclosed herein can capture a humid, or saturated, or superheated exhaust stream, such as from a kettle vent, and dilute the exhaust with fresh air to lower the temperature of the combined air flow below its dew point. Water is drained from the system as it condenses in the system. The combined air flow can be further diluted and/or treated according to embodiments disclosed herein such that the exhaust stream, after having excess water removed, will have a relative humidity (RH) value enabling it to be run through a media scrubber.

To provide an aroma diffusing device and a method of controlling an aroma diffusing device that can enable a plurality of functions to be achieved by operation inputs to one operation input part. Provided is an aroma diffusing device including: a perfume holding part in which a perfume is held; an air blowing source configured to supply air to the perfume holding part; an aroma discharge part through which the air having passed through the perfume holding part is discharged; an operation input part on which an operation input for the air blowing source is performed by a user; and an air blowing source control part configured to control a supply state of the air on the basis of an operation input on the one operation input part.

Vertical growing uses a plurality of shelves to support plants. The system has an air filtration and ultraviolet (UV) air purification system. The purified and filtered air is mixed with nitrogen, which is directed towards plants. The system can include lights to help grow the plants placed on the shelves. The filters can remove odors from the circulating air.

A microfluidic delivery device and method of dispensing a fluid composition from a microfluidic die are provided. The method includes generating air flow from a fan; directing a first portion of the air flow through a first air outlet in a housing; directing a second portion of the air flow through a second air outlet in the housing; jetting a fluid composition from a microfluidic die through a fluid orifice in the housing; directing the second portion of air flow adjacent to the microfluidic die and out the fluid outlet, wherein the first portion of the air flow directs the fluid composition jetted out of the fluid outlet into the air.

The present application relates to a fragrance atomization and diffusion device convenient for replacing a fragrance liquid container. The fragrance atomization and diffusion device convenient for replacing a fragrance liquid container comprises a housing, an atomization mechanism, a bottom cover and a top cover respectively located at two ends of the housing and enclosing a chamber, a bracket fixedly mounted within the chamber, a gas supply assembly and a power supply assembly, the atomization mechanism, the gas supply assembly and the power supply assembly each mounted at the bracket; the bracket is provided along the vertical direction with a mount cavity for mounting the atomization mechanism, an end of which extends through the top cover; and the atomization mechanism comprises an atomization head and a liquid storage bottle connected to the atomization head. The present application has the advantage of convenient addition of a fragrance liquid.
