An improved flow rate metering device that provides for the mixing and dispensing of two or more fluids to form final mixture, for example, for automatic washing of cars and trucks. More specifically, the invention is a system that mixes and ejects chemicals, creating a very precise mixture of one or more chemicals with a dilutant, such as water. The device also has the capability of monitoring an entire chemical dilution and release system, comprising multiple chemicals, and using software to document past and current usage rates, along with predicting future usage rates based upon both past usage rates and environmental conditions.

A cartridge designed to dispense fluid via atomization is provided. The system generally comprises a cartridge, fluid, manifold, and air supply, wherein the air supply injects air through the manifold and into the cartridge through an air inlet of the cartridge. The air is manipulated by the cartridge in a way that creates a stream of fast-moving air above a fluid within the cartridge. This results in a zone of lower pressure above the fluid that results in the fluid to be suctioned into said stream of fast-moving air where it is atomized. The atomized fluid is then carried by the stream of fast-moving air out an atomization outlet where it is dispersed within the environment.

A system includes a material sensor system having an inlet and an outlet. The inlet receives a flow of a material and the outlet outputs the flow of the material. The material sensor system includes an inner cavity having a surface, where the inner cavity receives the flow of the material. The material sensor system also includes a float system having one or more floats, where the one or more floats float within the material of the inner cavity. The material sensor system also includes a switch that sends one or more signals to a control valve system when the float system engages the surface of the inner cavity.

A method of processing a substrate may include preparing the substrate, polishing the substrate, and cleaning the substrate using a double nozzle, which is configured to provide a spray and a chemical solution onto the substrate. The spray may include a deionized water, and the chemical solution may be diluted with the deionized water. The chemical solution and the spray may be spaced apart from each other by a distance of 7 cm to 12 cm.

A device for coating a cylinder includes a coating head capable of being inserted into the cylinder, a plurality of coating guns which are provided on the coating head and are configured to discharge a coating material in a direction intersecting a longitudinal direction of the coating head, and a rotating cover which, when the coating material is discharged from one of a first coating gun and a second coating gun among the plurality of coating guns, is configured to cover the other of the first coating gun and the second coating gun, in which the plurality of coating guns are connected to coating material supply devices of different systems, respectively.

An atomization container includes a container body and an atomizer, wherein the container body has an accommodating cavity therein, the atomization container also has a gas inlet passage and a mist outlet passage, the gas inlet passage has one end configured to be connected with an external gas source and the other end connected with the atomizer for providing gas flow for the atomizer, the atomizer is configured to mix and atomize the gas flow provided through the gas inlet passage and liquid in the accommodating cavity to form mist, the mist outlet passage is configured to discharge the mist out of the container body, and the atomizer is located in the accommodating cavity.

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.

Afforded is a spraying apparatus that enables the large-volume generation of fine particles having particle diameters minute to a level that can give rise to Brownian motion. A spraying apparatus of the present invention is furnished with: an atomization tank 11 enabled for storing a liquid formulation; an atomizing device 12 being ultrasonic vibration elements arranged in the atomization tank interior, for atomizing the liquid formulation to generate fine particles; a blower 13 furnished with a blower element enabled for maintaining predetermined rpm, for blasting into the atomization tank interior, through a blow port 11b provided in the atomization tank, conveyance air that is for conveying the fine particles of the liquid formulation; a send-out port 11c, provided in the atomization tank, through which the fine particles are sent out together with the conveyance air; and a baffle plate 14a arranged in the atomization tank interior so as to receive liquid columns of the liquid formulation, produced by the ultrasonic vibration elements; wherein the baffle plate and the send-out port are arranged so that conveyance air supplied through the blow port goes through a gap between one end part 14ae of the baffle plate 14a and the atomization tank, winds in along the surface on the plate's liquid-column receiving side and then arrives at the send-out port.

A control unit performs control such that, in a state where water does not flow into a water path, an on-off valve is opened to supply air from a second air path to the water path and a mixed solution path to discharge residual water and thereafter supply of the air is stopped.

The disclosure herein concerns a method including receiving at a computer at least one target value of a scent parameter for an environment that is remote from the computer, receiving at the computer a sensed parameter of the environment, and controlling, via the computer, diffusion of a liquid from a source of the liquid in fluid communication with at least one scent diffusion device to achieve the target value of the scent parameter, wherein controlling includes setting or adjusting an operation parameter of the at least one scent diffusion device in response to the sensed parameter.
