A liquid spray system (1e) and method of using a liquid spray system is shown. The spray system (1e) comprises a receptacle (100e) for holding liquid to be sprayed, a support structure (200e) for supporting the receptacle (100e), a spray applicator (300e) disposed remotely from the support structure (200e) and an air pressurising device for driving the liquid out of the receptacle (100e) and for mixing with the liquid at an outlet of the spray applicator (300e). Advantageously, the spray system (1e) is compact and versatile.

A method of using a system to apply liquid over a selected area includes providing a source of liquid, a first tube for transporting liquid from the source through the system, a connector, a check valve and a spray device. The connector includes a projection extending into the first tube. The projection has an inlet in fluid communication with the first tube. The connector further includes an outlet and a passageway in fluid communication with the inlet of the projection and the outlet of the connector. The check valve has an inlet in fluid communication with the outlet of the connector and an outlet. The check valve is operable to permit the passage of liquid from the inlet to the outlet upon pressurization of the liquid above a threshold pressurization level. The method includes the steps of introducing an amount of liquid to be applied to the selected area from the source of liquid to the first tube at a pressure below the threshold pressurization level of the check valve and providing pressurized air through the first tube to pressurize the liquid in the first tube above the threshold pressurization level of the check valve, thereby transporting liquid from the first tube, through the connector and the check valve and through the spray device in response to pressurization of the liquid. The liquid may be ozonated water.

The present invention relates to a system (1) and a method for coating a surface (3a) of an object (3) with a spray coating tool (2) spraying atomised coating particles (10) onto. A conditioning hood (20) is applied defining a spray chamber. In operation the spray coating tool (2) is mounted at a coating tool mounting end (21), and an output end (22) is positioned in proximity of the surface (3a) of the object (3) to be coated. The spray coating tool (2) is operated to spray atomised coating particles (10) which travel from the coating tool (2), through the spray chamber and the output end (22) to the surface (3a) of the object (3). A carrier gas is injected that in operation carries the atomised coating particles (10) to the surface (3a) of the object (3).

A first wing is configured to have a first distance from first contact surface of a first pump diaphragm. A second wing is configured to have a second distance from a first contact surface on a second pump diaphragm, and a third wing is configured to have substantially the second distance from a first contact surface on a third pump diaphragm.

A rotary atomization device includes a housing, a blowing device, a rotating drive device, a rotating shaft, a gas tube and an atomizing structure. The housing has an atomization room and a containing room which are communicated by a gas channel. The blowing device is arranged in the containing room, and the rotating drive device is arranged in the containing room or the atomization room. A drive shaft of the rotating drive device is connected with the rotating shaft connected with the gas tube. One end of the gas tube is arranged in the atomization room and has a gas inlet, and the other end is extended out of the housing and has a gas outlet. The atomizing structure is disposed on the bottom of the atomization room, and the blowing device blows towards the gas channel. The rotary atomization device can realize rotary spraying.

This disclosure provides methods and systems that comprise a misting unit for atomizing a water-based or solvent-based composition, such as a liquid composition thereof to create a mist. Further, the disclosed methods and systems may include introducing, through an airtight aperture in a pipe or substrate, the mist into the pipe or the substrate. Further still, the disclosed methods and systems may include propelling, by an inert or non-inert gas, the mist onto at least a portion of the interior surface of a substrate connected to or integrated with the pipe within a closed system. The misting unit may be removably or irremovably connected to the pipe for optionally removably connecting to the substrate.

A hybridized shower apparatus is a hygienic aid that is directed towards adding additional functions to a conventional shower by introducing a second dispensation mode, in addition to conventional water jets. The hybridized shower apparatus uses a first fluid supply and a second fluid supply connected to a fluid selection mechanism via a first conduit and a second conduit. The fluid selection mechanism is further connected to a first annular chamber and a second annular chamber positioned within a dispersal head. The fluid selection mechanism selectably pressurizes the first annular chamber or the second annular chamber with the first fluid supply and the second fluid supply, respectively. The selected fluid is subsequently dispensed through the dispersal head onto a target region, typically a user's head and shoulders.

An atomization powder making device suitable for atomizing molten metal to produce powder includes a housing defining an atomizing chamber, a vessel mounted inside the housing and defining a receiving space for receiving the molten metal, and a flow guide unit extending from the bottom of the vessel and having at least one liquid flow channel for conveying the molten metal from the receiving space to the atomizing chamber. A push unit is disposed in the receiving space for pushing the molten metal to flow through the at least one liquid flow channel. A gas supply unit is configured to supply an atomizing gas for atomizing the molten metal flowing out of the liquid flow channel.
