A spray ionization device comprising: a first pipe body that has a first flow path which allows a liquid to flow therethrough, and has, at one end thereof, a first outlet through which the liquid is sprayed out; a second pipe body that surrounds the first pipe body; and a third pipe body that surrounds the second pipe body with a space interposed therebetween, that has a second flow path allowing a gas to flow therethrough, and that has a second outlet at the one end. At least the leading end part of the third pipe body including the second outlet is made of an electrically conductive material so as to serve as an electrode. Charged droplets can be sprayed from the second outlet by applying an electric field to droplets sprayed from the first outlet using a power supply connected to the electrode.

Provided are nozzle assemblies for a spraying apparatus having an outer wall (146) having opposed inner and outer surfaces, a central aperture (136) extending through the outer wall, and a pair of auxiliary apertures (158) disposed on the outer wall (146). Each auxiliary aperture is aligned along a respective auxiliary axis (162) and areas of the inner surface (164) of the outer wall (146) adjacent to the auxiliary apertures (158) are countersunk to define ledges (166) that are axially symmetric about the auxiliary axes (162). These assemblies obviate problems associated with rotatable molding pins and also provide the unexpected advantage of providing axial alignment of the air flow profile as air is emitted from the auxiliary apertures.

A sprayer includes a spray gun and a hopper. An air source provides compressed air to the sprayer to both eject fluid from the spray gun as a spray and to pressurize the hopper. The spray gun includes passages for providing compressed air to the nozzle for spraying and to the hopper for pressurizing the hopper. The spray gun further includes a relief valve for venting pressurized air from the hopper. The hopper receives the compressed air through a port in the hopper, and the compressed air assists the flow of material out of the hopper and into the spray gun.

A spraying device with air atomization and pneumatic drive, including at least one air valve for controlling a spraying air flow through the spraying device, at least one media valve for controlling a media flow through the spraying device, at least one first pneumatically actuated drive piston for actuation of the at least one air valve and at least one second pneumatically actuated drive piston for actuation of the at least one media valve.

The invention provides a method of packaging a sterilized product. The method includes the steps of providing a product and sterilizing the product. The sterilized product is enclosed in a first layer, which is substantially hermetically sealed to form a first sealed enclosure. The first sealed enclosure is enclosed in a second layer, which is substantially hermetically sealed to form a second sealed enclosure. The second sealed enclosure is enclosed in a third layer, which is substantially hermetically sealed to form a third sealed enclosure. The third sealed enclosure is enclosed in a fourth layer, which is substantially hermetically sealed to form a packaged product.

A printer is configured to provide a jet of extraction gas that extracts a printing fluid from a printing nozzle in the presence of an electric field that accelerates the extracted printing fluid toward a printing substrate. The printer is also configured to selectively turn the electric field and the jet of extraction gas off and on to enable printing in gas-extraction mode, an e-assisted gas-extraction mode, or an e-jet mode. The jet of gas can be provided by a second nozzle concentric with the printing nozzle. A third nozzle can discharge a focusing gas around the extracted printing fluid.

A fine particle sprayer including a nozzle for dispersing a liquid disinfectant into a spray plume of droplets and a means for directing pressurized air below the spray plume to increase droplet transfer efficiency, and above and around the spray plume to prevent errant droplets from drifting toward an operator. A sprayer system includes a sprayer, a housing, and a blower that may be removably attached to the sprayer for generating an air stream below the droplets to improve droplet transfer efficiency.

There is provided a spray gun configured to atomize a liquid by using a compressed gas. The spray gun comprises: a gas cap configured to inject the compressed gas; and a liquid nozzle configured to inject the liquid, wherein the gas cap comprises a center gas flow path that has an opening provided in a neighborhood of the liquid nozzle; and multiple pairs of side face gas ports provided outside of the opening, each pair of the side face gas ports being placed at positions symmetric to each other across a center of the liquid nozzle and being directed toward a center in an injecting direction of the liquid nozzle, and wherein control is made to individually regulate a pressure of the gas to be injected from each pair of the side face gas ports.

An essential oil reflux-type atomizer comprising the following structures: chassis, housing, atomization chamber, gas pump, gas tube, gas nozzle, oil nozzle, and filter atomization mechanism. The filter atomization mechanism is installed in the housing and has an upper filter and a lower filter. The essential oil atomizer can be improved efficiency and reduced noise level.

A multi-mode fluid nozzle includes a generally-cylindrical mixing chamber with a stream mode fluid inlet connected to one side of the chamber, a fluid outlet connected to the opposite side of the chamber and a plurality of mist mode fluid inlets connected to the periphery of the chamber. The discharge pattern of the multi-mode fluid nozzle is dependent upon the inlets from which fluid enters the mixing chamber such that when the fluid enters the mixing chamber through the stream mode fluid inlet, the fluid exits the fluid outlet in a stream flow discharge pattern, when the fluid enters the mixing chamber through the mist mode fluid inlets, the fluid exits the fluid outlet in a mist flow discharge pattern and when the fluid enters the mixing chamber through the stream mode and the mist mode fluid inlets, the fluid exits the fluid outlet in a droplet flow discharge pattern.
