A pilot valve switch mechanism of a shower system includes a fixed portion and a valve spool. The fixed portion is has an inlet waterway, a first and second outlet waterway and a control hole that can connect to the outlet waterways. The first outlet waterway has a first outlet and the second outlet waterway has a second outlet. The valve spool is slidably assembled inside the fixed portion vertically to the inlet waterway, and has a slim hole connected to the inlet waterway. The valve spool and the fixed portion form a pressure cavity. The control hole and the slim hole are connected to the pressure cavity. The pressure cavity is controlled by the control hole to drive the valve spool to move along the inlet waterway to close the first or second outlet, switching the inlet waterway to connect to the first or second outlet waterway.

A multi-mode fluid nozzle includes a 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 at least one mist mode fluid inlet connected to the periphery of the chamber. The discharge pattern of the nozzle depends upon the inlets 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 at least one mist mode fluid inlet, 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 at least one mist mode fluid inlets, the fluid exits the fluid outlet in a droplet flow discharge pattern.

A shower head adapted to receive a supply of water from a water heater, the shower head including a controller functionally connected to the water heater, a proximity sensor, a temperature sensor and a valve, all of which are functionally coupled to the controller. The proximity sensor is configured to detect a demand as indicated by the detection of an object within the detection range of the proximity sensor. The temperature sensor is adapted to measure the temperature of the supply of water. If a demand is determined to exist and the water supply temperature is determined to be outside of a range of ideal temperature, the valve is opened to allow draining of the supply of water until the temperature of the supply of water falls within the range of ideal temperature and if the demand continues to exist, the valve is configured to remain open.

A top spraying shower head with reset function comprises a shower head main body having: a waterway switch valve, an inlet passage, a first outlet hole, and a second outlet hole concentrically arranged in the direction of the inlet passage. The inlet passage with the first outlet hole or the second outlet hole form a first outlet passage and a second outlet passage respectively. The waterway switch valve comprises: a valve body having a slidable valve body that moves between a first position and a second position to close the first outlet passage or the second outlet passage; a sealing element which can open the first and second outlet passage; an elastic element abutting between one end of the valve spindle and the inner wall of the valve body; and a W-shaped camshaft rotatably assembled in the valve body.

A fluidic oscillator assembly can include at least one fluidic oscillator, and a closure that in one position prevents flow through the oscillator to an exterior of the assembly, and in another position permits flow through the oscillator to the exterior. A method can include flowing fluid longitudinally through a fluidic oscillator assembly in a well, then diverting the fluid to flow outward from the assembly via at least one fluidic oscillator, the fluid being prevented from flowing longitudinally through the assembly. A well system can include a drill string having a fluidic oscillator assembly, a drill bit, and a drilling motor disposed between the drill bit and the assembly. The assembly can include a closure that in one position prevents fluid flow through a fluidic oscillator to an annulus formed between the drill string and a wellbore, and in another position permits fluid flow through the oscillator.

A dishwasher includes a tub at least partially defining a treating chamber and a sprayer for spraying liquid to the treating chamber. The sprayer may include a liquid passage provided in the interior of the body, at least one upper outlet extending through the upper surface of the body and in fluid communication with the liquid passage, at least one lower outlet extending through the lower surface of the body and in fluid communication with the liquid passage, and a valve body moveable relative to the body to fluidly couple the at least one upper outlet and the at least one lower outlet to the liquid passage.

A multi-mode fluid nozzle includes a 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 at least one mist mode fluid inlet connected to the periphery of the chamber. The discharge pattern of the nozzle depends upon the inlets 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 at least one mist mode fluid inlet, 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 at least one mist mode fluid inlets, the fluid exits the fluid outlet in a droplet flow discharge pattern.

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.

The present disclosure provides a showerhead assembly. The showerhead assembly comprises a handheld showerhead, a third fixing element, and at least one accessory. The handheld showerhead comprises a first main body and a first fixing element. Wherein the first main body comprises a through hole, the first main body comprises a water outlet surface and a back surface opposite to the water outlet surface, and the through hole penetrating through the water outlet surface and the back surface. The first fixing element and the third fixing element matches with each other to make the third fixing element be installed in the through hole of the first main body, or be removed from the through hole of the first main body easily. The at least one accessory is fixed in the through hole by the third fixing element and protrudes out of the water outlet surface.

A shower head with automatically resettable spray gun includes a shower head body including a water passage switching mechanism, a shower head, and a spray gun head which respectively communicates with the water passage switching mechanism. The water passage switching mechanism includes a water passing member and a water passage switching unit. The water passing member includes a water inlet, a water passage switching cavity communicating with the water inlet, a shower head water passage and a spray gun water passage which respectively communicates with the water passage switching cavity. The water passage switching unit arranged in the water passage switching cavity includes a button arranged at the water passing member by hinge joint, a switching link rod arranged at a lower portion of the button, and an elastic member connected between the switching link rod and the water passage switching cavity.
