A showerhead is disclosed including a first nozzle, a second nozzle, and a massage mode assembly in fluid communication with a fluid inlet, the first nozzle and the second nozzle. The massage mode assembly includes a turbine, a cam coupled to the turbine defining a dwell edge that extends between a leading corner and a follower corner, and a shutter movably coupled to the cam, where movement of the turbine causes the cam to drive shutter between a first position covering the first nozzle and opening the second nozzle and a second position opening the first nozzle and covering the second nozzle.

A rotating sprinkler for irrigation is disclosed. The sprinkler can include a turret and a stream conditioner positioned in the turret. The stream conditioner can include a plurality of fins forming a plurality of flow regions. One or more of the plurality of flow regions can have a cross-sectional flow area that decreases in a downstream direction towards the primary port so as to accelerate the pressurized water through the stream conditioner. The plurality of fins can further straighten the water.

An oscillating sprinkler assembly includes a body including an inlet configured for connection to a water supply; a riser movably mounted in the body and movable from a retracted position to an extended position; a nozzle housing rotatably mounted on a top of the riser; a pressure regulating assembly mounted at an inlet of the riser and operable to control pressure of water into the riser based on an downstream pressure; a water turbine mounted downstream of the pressure regulating assembly such that water from the pressure regulating assembly passes through the water turbine to rotated one or more blades thereof, wherein the one or more blades are operatively connected to the nozzle housing and drive rotation of the nozzle housing; and a bypass valve, provided between the pressure regulating assembly and the water turbine and operable to control water flow to the water turbine.

A showerhead with a massage engine is disclosed. The showerhead may include a housing defining a chamber in fluid communication with a fluid inlet and a massage mode assembly received within the chamber. The massage mode assembly may include a drive gear comprising a plurality of drive teeth, wherein the drive gear rotates due to fluid from the fluid inlet impacting the drive gear, and a driven gear comprising a plurality of driven teeth that mesh with the drive teeth of the drive gear, such that movement of the drive gear causes the driven gear to rotate, wherein the drive gear rotates faster than the driven gear rotates to selectively direct fluid from the fluid inlet to one or more nozzles.

A mechanism is described to resist or prevent rotation of portions of an irrigation sprinkler riser when in its lowered or popped-down position. Hence, when a pedestrian walks over a lowered sprinkler or a lawn mower rolls over a sprinkler, for example, the riser will remain fixed in its rotational orientation relative to its outer body and surroundings. By resisting or preventing this rotation, this rotational locking mechanism prevents damage to the internal transmission, gears, and arc trip mechanisms of the sprinkler, as well as prevents the watering arc from being accidentally adjusted.

A sprinkler module is cooperable with a sprinkler nozzle unit supporting a sprinkler nozzle to define a sprinkler configuration. The sprinkler module includes a cage attachable to the sprinkler nozzle unit and including a pair of struts, a cap connected to the cage via the pair of struts, and a deflector plate cooperable with the sprinkler nozzle and rotatably secured between the cap and the cage. The deflector plate includes a hub extending through the cap. A plate gear with gear teeth is secured to the hub and is rotatable with the deflector plate, and a cover assembly is connected to the cap. The cover assembly includes a brake gear coupled with a brake assembly, where the brake gear is disposed in a path of the gear teeth.

A showerhead assembly is provided which includes an outer housing and inner housing. The inner housing includes a support disk and gear housing disk for housing a selector wheel having a slot. The outer housing includes the base and a faceplate having nozzle systems connecting to complementary orifices. Water enters the internal housing via a channel where it is further diverted by the diverter arms so as to impinge on a gear train's bladed rotor, causing the gear train's individual components to rotate. Upon the rotation of the selector wheel, the selector wheel's slot aligns with a selected orifice whereby water travels through and enters a corresponding nozzle system. This sequence continues, causing water to sequentially spray from individual nozzles in systematic intervals so as to create a strobe-like spray pattern.

The present invention relates to a novel sprinkler device. The device is designed to prevent the spread of wildfires to residential areas. The device comprises a plurality of sprinkler nozzle heads secured to a pole component. Each sprinkler nozzle head comprises a built-in sensor that will detect the presence of a fire, automatically activating the sprinkler nozzle head to extinguish a fire. Further, each sprinkler nozzle head comprises a backup system in case of a power failure, or the sensor fails. Further, the sprinkler heads can comprise a solar-powered battery and a manual power switch.
