A water spray gun has a grip with an inlet passage, a branching structure connected to the top portion of the grip, and an outlet structure connected to the branching structure. The outlet structure is internally formed with a plurality of outlet passages each corresponding to a different setting of the water outlet mode of the outlet structure. The branching structure has a transverse through-hole to be interconnected to the inlet passage and the plurality of outlet passages; a controlling component fitted inside the through-hole in a rotary mode and being provided to seal the opposite ends of the through-hole; and a triggering piece connected to the controlling component and provided to drive the controlling component to rotate in relation to the inner wall of the through-hole, so as to introduce the water delivered into the grip from the inlet passage into a corresponding outlet passage inside the outlet structure.

To keep a discharge pressure or a discharge flow rate of a pumping system that jets a fluid from a nozzle selected from a plurality of nozzles a set value every selected nozzle. A pumping system that jets the fluid from the nozzle selected from the plurality of nozzles is provided with: a piston pump as a positive-displacement pump; a permanent-magnet type synchronous motor as a rotational speed variable drive unit; a turret device as selecting arrangement; a discharge pipe; the nozzle; a controller that controls the rotational speed of the drive unit; a storage that stores control parameters and a target value of the discharge pressure corresponding to each nozzle; and a pressure sensor, wherein the controller controls the rotational speed of the drive unit by feeding back the discharge pressure using the control parameters corresponding to the selected nozzle to match the discharge pressure with the target value.

A switchable shower head includes a waterway device providing at least two water flow outlet functions; and a waterway switching device including a water diversion plate rotatable to switch between outlet functions; a fixing seat disposed above the water diversion plate; a ratchet wheel coaxially connected to and synchronously rotatable with the water diversion plate via the fixing seat and including a ratchet; a transmission element that abuts against the ratchet to cause the ratchet wheel to rotate; a transmission rack that has the transmission element slidably assembled thereto to slide in a sliding direction, that is movable with respect to the ratchet wheel in a moving direction, and that is resettable by two or more elastic elements; and a driving device that comprises a press button in communication with the fixing seat and a driver mechanism provided between the press button and the transmission rack.

A water stop switch shower head includes a water stop element, a water diversion plate, a water diversion body, a switch element and a switch shaft; the switch element is linked to the water diversion plate, the switch element and the water diversion plate rotate respectively around the switch shaft; one end of the water stop element is faced to the water diversion plate; the water diversion plate is disposed with a non-abutting surface and an abutting surface at the surface faced to the water stop element, the non-abutting surface and the abutting surface have height difference transitioned by an incline surface; the switch element is operated to drive the water diversion plate to rotate, when the water stop element faces to the non-abutting surface, the water stop element is contacted with the inner wall of the inlet in sealing way.

A multi-mode fluid nozzle includes a generally-cylindrical 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 a plurality of mist mode fluid inlets connected to the periphery of the chamber. The discharge pattern of the multi-mode fluid nozzle is dependent upon the inlets from which 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 mist mode fluid inlets, 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 mist mode fluid inlets, the fluid exits the fluid outlet in a droplet flow discharge pattern.

A multi-function shower head for automatically adjusting a water flow spray pattern upon interrupting water flow. Such a shower head includes an upper housing having an open end for water entry, a lower housing coupled to the upper housing opposite the open end thereof and defining therewith a recessed locating cavity, a base plate received in the recessed locating cavity, the base plate having at least water passages and direct spray holes there-through for selectively enabling water outflow from the upper housing through the base plate in a first spray pattern and at least a second spray pattern, a sliding ring held by the lower housing against the base plate and having at least second spray pattern holes therein, at least one manual actuating means for rotating the sliding ring relative to the base plate and thereby selectively align the second spray holes in the sliding ring with the water passages in the base plate, and a means for automatically adjusting the water flow from the second spray pattern to the first spray pattern upon interrupting water flow through the base plate.

A remote switch combination shower head includes a first shower head, a second shower head and a switch mechanism, wherein further comprising a fixing seat assembled to a support arm, the fixing seat is disposed with an inlet waterway connected to the support arm, a first diversion waterway and a second diversion waterway; the first shower head is assembled to the fixing seat and is capable of connecting to the first diversion waterway; the second shower head is a hand shower head connected to the second diversion waterway by a flexible pipe; the switch mechanism comprises a switch component and an operation component, the switch component is disposed to the fixing seat and is coupled to the inlet waterway, the first diversion waterway and the second diversion waterway, so that the waterways are switched by the movement of the switch component.

A nozzle for water jet equipment and a method of use thereof. The nozzle has a body including a base with a shaft extending outwardly therefrom. The shaft is inserted through a bore of a sleeve that rotatable about the shaft. The base and shaft define a bore therein. At least one opening is defined in the shaft and one or more grooves are milled into the shaft's exterior surface. Each opening places the body's bore in fluid communication with one of the grooves and the sleeve's bore. Water flowing through the body's bore will flow through each opening, into the associated groove and into a space between the shaft and sleeve. The grooves create turbulence in water in this space and thereby reduce leakage from the nozzle. The shaft terminates in a conical section usable as a battering ram to break up blockages in pipes during cleaning operations.
