In accordance with embodiments of the invention, a portable face rinsing faucet attachment is provided. The portable face rinsing faucet attachment includes a body. An intake channel is operable for attachment to a faucet to receive pressurized water from the faucet. A flow path is defined by the body and is in fluid communication with the intake channel. The flow path is operable to receive pressurized water from the intake channel. A plurality of spray channels is defined by the body and are operable to receive and pressurize water from the flow path. A plurality of spray holes is defined by the spray channels and are operable to receive and spray water from said spray channels. A drain is defined by the body.

An inductive electrostatic atomization nozzle includes a nozzle body. The nozzle body has an internal gas flow channel and a liquid flow channel surrounding the internal gas flow channel. An electrode ring is arranged around the liquid flow channel at an inlet of the liquid flow channel. In the inductive electrostatic atomization nozzle, the electrode ring is arranged at the inlet of the liquid flow channel, which ensures that the electrode ring is located far away from the outlet of the inductive electrostatic atomization nozzle.

The water-saving nozzle has an outer housing that includes an outer vortex screw in operative engagement with an inner housing that is disposed inside the outer housing. The vortex screw has helical threads. The inner housing has an inner vortex screw with outside helical threads. When water passes through the outer and inner vortex screws the water is rotated before the water passes into the vortex chambers of the inner and outer housings. The water discharged from the outer housing forms an outer dome shape and the water discharged from the inner housing forms an inner dome shape inside the outer dome shape.

A high efficiency nozzle is designed. The nozzle allows water streams with long-range and high surface area in one system. Suitable transitions in the fluid pathways allow creating water streams that have a robust flow profile. The system allows minimum energy loss whilst maximizing the velocity and surface area. Such nozzles can be used for a variety of applications including but not limited to fire suppression, pressure washing, watering, and other such applications.

A spray wand for use with a chemical or chemical formulation in solid form. The spray wand has a spray wand body having a hollow tube with an angled wand spray end, a spray end selector attached to the angled wand spray end, a wand hose end screen inserted into or otherwise attached to the hollow tube of the spray wand body, and a wand hose end connected to the spray wand body. The wand hose end has a wand hose end valve for control of water flow from a hose. A refill cartridge having a swirl chamber may be attached to the hollow tube. The refill cartridge has external channels or grooves on its external surface as a water rinse feature for the spray wand.

A paint bell cup for directing a spray of paint onto a surface includes a cup body having an outer surface, an inner conical surface having a circumferential edge, and a stem extending from the outer surface. The stem includes a passage that delivers paint toward the inner conical surface. The cup body includes one or more spray control features that extend along the inner conical surface toward the circumferential edge. The one or more spray control features promote a selected uniform droplet size of the paint traveling from the stem toward the circumferential edge.
