A multi-function pull-out spray head includes a housing, a switching assembly, and a water discharge assembly. The water discharge assembly forms at least three water outlet areas. The switching assembly includes a first inner body, a second inner body, a first switching control unit, and at least two second switching control units. The first inner body has a communicating flow passage made by core-pulling technology in a direction parallel to a water flowing direction. The multi-function pull-out spray head is not easy to leak water and has the characteristics of high yield.

The present invention relates to a shower head which comprises a dispenser for optionally or selectively dispensing a fluid additive such as soap, simultaneously or separately with the water. The invention discloses an innovative mechanism using optimized fluid mechanics for spraying water or cleansing solution for a more hygienic and overall cleansing experience.

A water accelerator with a body and a channel extending along an axis X through the body from a water inlet to a water outlet. The channel includes an inlet section having a first substantially constant diameter D1. The inlet section connects directly to an acceleration section. The acceleration section has diameter D2 decreasing in the flow direction. The acceleration section connects directly or via a constant diameter section to an action section. The action section has a diameter D4 increasing in the flow direction. The increase of the diameter D4 of the action section starts gradually. An air admission channel extends through the body from the exterior of the body to the action section and/or to a section of the channel subsequent to the action section in the flow direction.

A spray device includes a converging assembly, a container and a suction pipe. The converging assembly includes a first liquid channel, a second liquid channel, a first air channel and a second air channel. The first liquid channel and the first air channel communicate with an inlet of the second liquid channel. The second air channel communicates with the container. An end of the suction pipe communicates with the inlet of the second liquid channel, and another end is submerged in a solution in the container. When a liquid flows from the first liquid channel to the second liquid channel, air in the first liquid channel is discharged via the first air channel, the solution is sucked to the second liquid channel through the suction pipe, the solution and the liquid are mixed at the inlet of the second liquid channel, and then are sprayed from the second liquid channel.

A ball joint connector is provided for linking a showerhead to a water supply pipe. The connector has an internal venturi that draws air into the connector to aerate water being provided to the showerhead. A flow control member is disposed in a fluid pathway connected to the venturi, preventing spraying or leaking out the air inlet, while reducing noise associated with the air induction.

A spray head contains: a shell and a waterway which includes a body, a side plate, and a spray face. The side plate covers on the body so as to define a first conduit, a second conduit, and a third conduit among which a water-diverting valve chamber is defined and accommodates a water-diverting valve, a button is connected with the water-diverting valve, a spring is fixed between the water-diverting valve and the water-diverting valve chamber, an aerator is mounted on the spray face which includes multiple spray nozzles. The body further includes a first cliff, a first fence, a first cavity, a first space, multiple first grooves, and multiple second grooves. The spray face includes a panel, a second cliff, and a second fence which has multiple locking tabs, wherein the second cliff has a second cavity, between the second cliff and the second fence is defined a trench.

A thermal regulation apparatus for pool water is an apparatus that is used to regulate the overall temperature of a pool in an efficient and cost-effective manner. The apparatus may include a water-jet adapter, a tee tubing connector, a valved spout, a valved drain, and an extension pipe. The water-jet adapter enables the apparatus to be connected to a water return jet and serves as the main water inlet of the apparatus. The tee tubing connector distributes the water inflow from the water-jet adapter to the valved drain and the extension pipe. The extension pipe guides the water inflow towards the valved spout. The valved spout serves as the main outlet for the apparatus and enables the cooling of the water outflow that is diffused back into the pool. The valved drain serves as a secondary outlet for the apparatus and helps control the water flow through the apparatus.

An automatic control element has a sprinkler, a fluidic element connected to the sprinkler, and an outlet cover plate secured onto an outlet of the fluidic element. The fluid element further has a water inlet and a first air supply pore are symmetrically arranged on it. A second air supply pore is on the water inlet. A water distributor is formed on the sprinkler, a water tank is provided on the outer side of the sprinkler, and the water distributor is in communication with an inner cavity of the water tank. A signal nozzle is provided on the wall of the water tank, and the signal nozzle is connected to the water inlet via a conduit.

Wands are used as parts of cleaning systems to conduct cleaning agents into gas turbine engine cores. Wands according to the present disclosure include inlet assemblies adapted to connect to cleaning agents, dispensers adapted to discharge cleaners into gas turbine engines, and conduits that extend from the inlet assemblies to the dispensers.

The invention relates to a shower arm with a torus regulator and a magnetic ring that is comprised of a body (1) with a body head (25), a bell (2), a cover (3), a torus (4), a mixing element (5), a ring (6), a pin (7) and a barrier (9) on the cover, a barrier (8) and a nozzle (10) on the bell, a cavity (11) for water inlet, an inlet (12) of water into the shower head (25), a space (13), a gap (14) on the mixing element, a chamber (15), gaskets (16) and (17), a thread (18), a space (19) for directed flow, pins (20) and a groove (21) on the ring, a groove (22) on the bell, a thread (23) for connecting a hose, a support surface (24) a magnetic ring (26) and an output spray (27) of water and air. When the water circulates within the space (19) underneath the torus (4), negative pressure—vacuum occurs from both the internal and the external sides of the torus cross-section that conditions suction of the air from the chamber (15) of the cone of the bell (2). This air is suctioned through the nozzle (10). In the space below the mixing element (5) the air and the water swirl which alternately enter into the air/water mixture and form a wide conical spray (27). The bell is provided with the groove (22), into which the ring (6) with pins (20) is tightly inserted. The pins are made from a soft material and serve for mechanical massage of the skin and the crown of the hair. On the other side in the ring there is the groove (21), into which the magnetic ring (26) is inserted. Its role is to normalize the water crystals and to arrange them into a natural shape. The nozzle (10) for spray outlet has an orifice large enough in order not to clog due to impurities in the water and limescale.
