A dishwasher assembly may include a dishwasher rack including at least one drinkware row configured to hold drinkware along a length of the rack, a sprayer configured to provide at least one stream of liquid into the drinkware, and a paddle wheel assembly arranged between the drinkware row and the sprayer and including at least one paddle configured to rotate responsive to force of the at least one stream of liquid against the at least one paddle, such that during rotation the at least one paddle is configured to variably deflect at least a portion of the stream onto a plurality of portions of an interior surface of the drinkware.

A rotor nozzle structure has a chamber deployed with a rotor connecting to the water outlet and an adjusting element, wherein the rotor nozzle is capable of generating a directing stream and a wide-angle swirl stream, and the adjusting element is switchable by a rotational means for driving the rotor in a rotation or static status in the chamber.

A structure of rotor nozzle is equipped with a spray unit of a watering device, the spray unit is composed of a mounting member and a housing for defining a chamber, a rotor deployed inside the chamber; wherein, at least one stopper set on the inner side of the chamber near the water outlet side is correspondingly matched to multiple guide members on one end of the water outlet of the rotor, and it can be employable to the handy watering device.

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.

An incrementally rotating in-floor swimming pool cleaning head with a retainer body, a nozzle stem, a ratcheting pin, a cam unit having a plurality of cam teeth on an inner surface, and a removable top ring. The cam unit is stationary in relation to itself and without moving parts. When the cam unit engages the ratcheting pin in a first orientation, the nozzle stem reciprocally operates to ratchet in a clockwise direction, and when the cam unit engages the ratcheting pin in a second orientation, the nozzle stem operates to ratchet in a counter-clockwise direction. An outer surface of the cam unit comprises a positioning key that mates with the retainer body to positionally retain the cam unit during reciprocating use and a ratcheting surface permitting ratcheting rotation of the cam unit in a first rotational direction and restricting rotational movement in a second rotational direction.

An incrementally rotating in-floor swimming pool cleaning head with retainer body, a nozzle stem, a ratcheting pin, a plurality of cam teeth configured to engage the ratcheting pin, wherein the nozzle stem is configured to reciprocally ratchet, a top ring, and a reversible bayonet. The reversible bayonet includes a plurality of lugs on an inner surface of the reversible bayonet, the plurality of lugs closer to a second end than to a first end, and the plurality of lugs of configured to couple to a bayonet connector of the nozzle stem in each of a first orientation configured for a spring powered retracting nozzle, and a second orientation configured for a weighted retraction nozzle.

The present disclosure relates to an apparatus, in particular a shower head (100), having a water-driven or water-powered vibration function for massage purposes and/or for sexual stimulation. The shower head (100) preferably includes a hollow longitudinal main body (1), a water inlet (2) arranged on one side of the hollow longitudinal main body (1), one or more water outlets la arranged on another side of the hollow longitudinal main body (1), a vibration member (8) arranged inside the hollow longitudinal main body (1) between the water inlet (2) and the one or more water outlets la, and a switching mechanism (11) configured to switch between a first state in which the vibration member (8) is movably released inside at least a portion of the hollow longitudinal main body (1) and a second state in which a position of the vibration member (8) is fixed.
