An improved structure of gyrating nozzle spray gun includes a grip including an air inlet and a trigger-controlled valve seat, a gas delivery tube connected to the valve seat, and a gyrating nozzle head including a connection nut threaded onto a front tubular mating connection screw rod of the gas delivery tube, an end cap threaded onto outer thread of the connection nut, a bearing positioned in the end cap, and a rotator mounted in the bearing and rotatable with an inner race of the bearing and defining therein a gas accumulation chamber for receiving compressed air from the valve seat via the gas delivery tube and the connection nut and an oblique jet hole eccentrically located in the front wall thereof for ejecting compressed air and causing the rotator to rotate during ejection of compressed air.

A rotating distributor for use in a rotary type sprinkler is conically shaped and includes a plurality of water channels provided on a bottom surface thereof to guide water from a center axis of the distributor radially outward to an outer circumference of the distributor. The grooves are provided to collect and guide the water with a minimum of spray and turbulence and to impart rotation on the distributor. The depth of the grooves may be used to control flow and range as desired. An elevation control ring may be provided to vary the elevation angle of water leaving the grooves to control range. A kick angle control element may be provided to modify a kick angle at an outer circumferential end of selected grooves to provide speed control, if desired.

A gyrating nozzle spray gun includes a grip including an air inlet, a valve seat, a gas-delivery tube connected to the valve seat and terminating in a mating connection portion and a trigger operable for letting external compressed air go into the air inlet and the gas-delivery tube, an attachment tube connected to the mating connection portion of the gas-delivery tube, and a gyrating pattern generator including a gas-supply tube connected to the mating connection portion and suspended in an accommodation chamber, a bearing mounted on a connecting portion, a coupling socket mounted on an outer race and a gyrating nozzle fastened to the coupling socket and rotatably disposed in an orifice and defining a gas accumulation chamber and an oblique jet hole for ejection of the intake flow of compressed air that goes through the air inlet, the gas-delivery tube and the gas-supply tube into the gas accumulation chamber.

A substrate treatment apparatus according to the embodiment includes: a nozzle which ejects a treatment liquid onto a treatment target surface of a substrate; a trajectory deflector including a trajectory deflecting surface, which is an annular inclined surface that deflects a traveling direction of the treatment liquid ejected from the nozzle and makes the treatment liquid incident on the treatment target surface, the trajectory deflecting surface having an inclination angle varying in a direction of annular extension of the trajectory deflecting surface; and a position changer which moves an incident position of the treatment liquid on the trajectory deflecting surface in the direction of annular extension of the trajectory deflecting surface.

An irrigation sprinkler can include a riser and a nozzle mounted at an upper end of the riser for rotation. The sprinkler can include a high flow rate port and a low flow rate port that can each emit a stream of water. The sprinkler can include a diverter valve that can intermittently block or permit the flow of water to the high flow rate port and/or to the low flow rate port as the nozzle rotates. The sprinkler can include a gear train reduction mounted in the riser and coupled to rotate the nozzle. A turbine can be coupled to an input shaft of the gear train reduction and can be rotatable by water flowing through the riser.

Spray nozzle systems and methods of use are described herein. The spray nozzle system may include a stationary tube, a rigid rotor, and a sub-medium supply source. The stationary tube may be in fluid communication with a pressurized air source. The substantially rigid rotor is in fluid communication with the pressurized air source. The substantially rigid rotor includes a substantially rigid conduit that is in fluid communication with the passages of the stationary tube and the rotor. A portion of the conduit is substantially arched such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis. Pressurized air ejected from the outlet produces directional components of the pressurized air in the direction of rotation about the rotor axis; and during use, the pressurized air rotates the rotor and sucks sub-medium from the sub-medium supply source into the stationary tube passage.

A showerhead with massage function is provided, which includes a showerhead water outlet tray and a water inlet seat. The showerhead water outlet tray is provided with a water outlet chamber, a bottom surface of the water outlet chamber is provided with a plurality of water outlet holes. The water inlet seat is provided on a top surface of the showerhead water outlet tray and communicated with the water outlet chamber. A top of the water inlet seat is provided with a water inlet joint connected to an external water source, and a water outlet nozzle is penetrated through the water outlet holes. A middle of the water outlet nozzle is provided with a joint that cooperates with inner walls of the water outlet holes to render the water outlet nozzle to swing in the water outlet hole and swing around the joint as a center.
