Methods and apparatus to deodorize fluids are disclosed. A disclosed example apparatus for deodorizing fluid from a fluid distributor includes a valve to enable the fluid from to enter a relief line from the fluid distributor, the relief line including an outlet, a bleed line to receive the fluid, the bleed line fluidly coupled to the relief line, a pressure tank fluidly coupled to the bleed line, the pressure tank to store a deodorant, and a deodorant line fluidly coupled between the pressure tank and the outlet, the fluid in the bleed line to urge the deodorant to the deodorant line.

A device for generating a scented mist of an atomized liquid fragrance oil includes an atomizer complex, a reservoir assembly, a drainage tube, and a vacuum tube. The atomizer complex can atomize the liquid fragrance oil into a scented mist and deliver the scented mist to air outside of the atomizer complex, where the liquid fragrance oil the fragrance oil that is not atomized into the scented mist delivered to the air outside of the atomizer complex includes collected oil that is collected and drained to a reservoir assembly. A drainage tube extends from a bottom area of the atomizer complex into the liquid fragrance oil. The device can filter the liquid fragrance oil in the reservoir assembly and the collected oil from the atomizer complex that drained down the drainage tube. The vacuum tube can suction the filtered liquid fragrance oil and the collected oil into the atomizer complex for atomization.

The present invention is a portable air purifier device intended to be attached to the belt or to the neck of the user and generate purified air enough to breath easily and adequate to make an air curtain to push a way ambient air. Principle of the operation of this device is to push inlet polluted air through layers of ionized water. Water will absorb particles and copper and silver ion kills possible air born bacteria and produce clean air. The purified air will be then delivered to the face of the user either by a flexible hose to a mask or through several flexible hoses to form an air curtain in front of a user's face.

Systems and techniques for cleaning and sanitizing objects are discussed herein. An object may include an unpowered object such as a shopping cart or a powered object such as a power wheel-chair. A sanitization structure may be connected to a reservoir and may apply a sanitizing agent to the object via one or more nozzles. A drying structure may apply filtered gas such as filtered air to the object via one or more air ducts. An ultraviolet (UV) light structure may apply UV light to the object via one or more UV lamps. A UV curtain structure may include one or more curtains that block the UV light. A bumper rail may guide the object received by the various structures from an entrance side to an exit side of the various structures.

A freshening composition and a consumer product that includes the freshening composition are provided. The freshening composition includes cyclodextrin; a silicone anti-foam agent, and a liquid carrier. The freshening composition includes a weight ratio of silicone anti-foam agent to cyclodextrin of less than 0.00375:1. A consumer product may include the freshening composition disposed in a spray dispenser.

A toilet bowl sanitizer includes a flush activated sprayer. The sprayer creates a barrier for contaminants from leaving the toilet bowl.

The present invention provides a smart speaker with fragrance dispenser. A housing is disposed below a lid. One or more air outlet, one or more air inlet, and one or more sound outlet are disposed on one side of the housing. A fragrance module is disposed on the inner side of the housing for outputting fragrance. A speaker and the fragrance module are disposed separately. A dot-matrix display is disposed on one side of the speaker. The speaker outputs sound and the dot-matrix display outputs light. A processor is disposed below the speaker and connected electrically to the fragrance module, the speaker, and the dot-matrix display for controlling the output of fragrance, sound, and light. The present invention further adopts a limiting member so that the lid can rotate and slide on the fragrance module.

Provided are a method and device for producing negative oxygen ions, and a method and device for purifying air. Said method for producing negative oxygen ions comprises: respectively introducing air and water into an air-water reactor so that the introduced air and water reach a relative movement speed of not less than 20 m/s in said air-water reactor and react within said air-water reactor so as to produce negative oxygen ions; and separating the air containing the negative oxygen ions after the reaction from the water after the reaction, and releasing the air containing the negative oxygen ions after the reaction into a required space. Said method and device can produce a large number of negative oxygen ions and purified air with a high efficiency at a low cost, without producing any harmful substances such as ozone and oxynitrides, and are long-acting and free of maintenance.

A method, system, and apparatus for sterilization, decontamination, and antimicrobial therapeutic treatment, which may include a dispensing device to cover a person, plant, animal, surface, enclosure, room or other structure or area with an antimicrobial solution. Radiation sources may expose the antimicrobial agent to a certain wavelength of radiation. The combination of the solution and the radiation may create a synergistic reaction that causes an effect greater than the radiation or solution separately. The same reaction creates a residual antimicrobial effect. A container, area or passageway including an dispensing device a solution so that a person, plant, animal or object is covered or saturated with an antimicrobial solution. Exposure to a certain wavelength of radiation creates a residual, synergistic reaction resulting in a supercharged antimicrobial agent that exhibits retained antimicrobial effects that exist longer than previously discovered due to the antimicrobial agent being exposed to the radiation together.

A device for generating a scented mist of an atomized liquid fragrance oil includes an atomizer complex, a reservoir assembly, a drainage tube, and a vacuum tube. The atomizer complex can atomize the liquid fragrance oil into a scented mist and deliver the scented mist to air outside of the atomizer complex, where the liquid fragrance oil the fragrance oil that is not atomized into the scented mist delivered to the air outside of the atomizer complex includes collected oil that is collected and drained to a reservoir assembly. A drainage tube extends from a bottom area of the atomizer complex into the liquid fragrance oil. The device can filter the liquid fragrance oil in the reservoir assembly and the collected oil from the atomizer complex that drained down the drainage tube. The vacuum tube can suction the filtered liquid fragrance oil and the collected oil into the atomizer complex for atomization.
