A nozzle configured to receive and disperse a high-pressure fluid or a low-pressure fluid is disclosed. The nozzle includes a nozzle body defining an open end, a closed end, and a side wall connecting the open end to the closed end, where the open end of the nozzle body configured to receive either the high-pressure fluid or the low-pressure fluid. The side wall defines a plurality of low-pressure apertures, a plurality of high-pressure apertures, and a compressible member positioned within the nozzle body. The plurality of high-pressure apertures are positioned downstream from the plurality of pressure apertures. The low-pressure apertures are smaller in size by a predefined ratio when compared to the high-pressure apertures. The compressible member is in an expanded position and blocks the plurality of high-pressure apertures when the open end of the nozzle body receives the low-pressure fluid.

Disclosed is an assembled shower device, that includes a hand-held type shower and a head portion shower. In the head portion shower is disposed a control mechanism. The control mechanism is adapted to control open or close of a water channel of the hand-held type shower, such that the hand-held type shower and the head portion shower act in cooperation in the following two approaches: the hand-held type shower is disposed on the head portion shower, to bring the control mechanism into action, to close the water channel of the hand-held type shower; and the hand-held type shower is separated from the head portion shower, to bring the control mechanism into action, to open the water channel of the hand-held type shower.

A water path switching device includes a valve body, a rotating shaft, a rotating plate, a first valve core and a second valve core. The valve body is provided with a valve cavity, a water inlet, and at least two water outlets. The rotating shaft is rotationally connected to the valve body, and is provided with an outer end located outside the valve cavity and an inner end located inside the valve cavity. The rotating plate is arranged in the valve cavity and connected to the inner end of the rotating shaft so as to rotate with the rotating shaft. The first valve core is provided with a first sliding-contact part.

A portable water path switching device includes a valve body, a water diversion member, and a switching assembly. The valve body is provided with a valve cavity, a water inlet communicating with the valve cavity, and at least two water outlets. The water diversion member is arranged in the valve cavity and at least provided with first water diversion holes and second water diversion holes. The first water diversion holes communicate with the first water outlet, and the second water diversion holes communicate with the second water outlet. The switching assembly is movably connected to the valve body and includes seal balls. When the switching assembly is driven, the seal balls switchably block the first water diversion holes and the second water diversion holes, so that water flow of the water inlet switchably flows to the second water outlet and the first water outlet.

A liquid discharge apparatus includes a liquid discharge head that discharges a liquid from multiple nozzle holes to apply the liquid to an object and circuitry that causes the liquid discharge head to discharge the liquid from a first number of the multiple nozzle holes to a first area at a start of an application of the liquid to the object as a first discharge, discharge a first total amount of the liquid to a receptacle different from the object before the first discharge as a first dummy discharge, discharge the liquid from a second number of the multiple nozzle holes to a second area at the start of the application as a second discharge, discharge a second total amount of the liquid larger than the first total amount to the receptacle before the second discharge as a second dummy discharge. The second number is larger than the first number.

A system for applying an agricultural product includes at least one control valve. For instance, the control valve has a moveable valve operator. One or more sensors monitor one or more control valve characteristics. A valve controller is configured to determine the control valve is in one or more of a primed state or an unprimed state based on a comparison of the one or more control valve characteristics to a primed valve characteristic threshold.

A bubble water generating device, including: a flow divider, a mixer, an air intake runner, and a water outlet cover the flow divider includes at least one first water inlet hole; a first chamber is formed between the mixer and the flow divider; the mixer includes at least one second water inlet hole corresponding to the at least one first water inlet hole one by one, and at least one return hole; the flow area of each second water inlet hole is greater than that of the corresponding first water inlet hole, the return hole, the first water inlet hole and the second water inlet hole are all communicated with the first chamber; the air intake runner is communicated with the first chamber; a second chamber communicating with the second water inlet hole and the return hole is formed between the water outlet cover and the mixer.

A shower head assembly includes a main body, a face plate, and a switching device installed inside the main body for controlling an outflow of water from the face plate. The circumferential portion of the face plate is provided with a plurality of water outlet units. Each water outlet unit includes a plurality of jet orifices for producing a plurality of fine spouts. Since the diameter of each jet orifice is small, the water discharge force of the fine spouts is stronger. The water-saving effect is good. The shower head can be used for a low water pressure environment.

The water outlet device comprises a water outlet component and a control mechanism, the water outlet component comprises a spherical chamber, a bottom of the spherical chamber comprises a water outlet hole, a top of the spherical chamber comprises a first water inlet, a side wall of the spherical chamber comprises a second water inlet, discharging water spray from the water outlet hole is controlled by flow rate variations of the first water inlet and the second water inlet, and the control mechanism cooperates with the first water inlet and the second water inlet to steplessly adjust the flow rate variations of the first water inlet and the second water inlet.

A nozzle assembly includes a hollow nozzle body having a central bore and a plurality of ports extending through the body from the central bore; a switching valve assembly disposed in the central bore that directs fluid flow to ports upon application of fluid flow above a predetermined threshold to the inlet and direct fluid flow to different ports upon fluid flow having subsequently dropped below the predetermined threshold and then exceeding the predetermined threshold; and a flow insert configured to replace the switching valve assembly for directing flow through all of the ports when switching functionality is not needed. This flow insert may be made of a low pressure material such as a polymer.
