Devices and methods for delivering fluid to the nasal cavity that include a delivery tube and cap configured to be connected to a container that houses the fluid. The delivery tube includes an inner cannula that is positioned within an outer cannula. Each of the cannulas includes a first outlet with one or more openings aligned along a first lateral section and a second outlet with one or more openings aligned along a second lateral section. The cap is configured to secure the delivery tube to the container. The delivery tube and cap are configured to provide relative axial movement between the cannulas. The cannulas are positionable between a first axial position that aligns the first outlets along the first lateral section of the delivery tube to deliver the fluid to a first portion of the nasal cavity, and a second axial position that aligns the second outlets along the second lateral section to deliver fluid to a second portion of the nasal cavity.

A nozzle assembly comprises a hollow nozzle body having a central bore and a plurality of ports extending through the body from the central bore; and 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. The assembly comprises a cylindrical poppet slidably disposed within the central bore, a guide between the nozzle body and the poppet, and a biasing member within the cartridge case between the front portion of the nozzle body and the poppet urging the poppet away from the front portion of the cartridge case.

A humanized switching device includes a tee pipe and a switching lever. The tee pipe has a switching chamber therein. The switching chamber is formed with a water inlet and a plurality of water outlets. The switching lever is provided with a water-stop part. The switching lever is movable to change the position of the water-stop part between the water inlet and the water outlets to realize the switching of the water passage. The structure is simple and easy to produce. The maintenance cost is low. The service life is longer. The structure is compact and takes up less space. The user can easily move the switching lever to switch the water passage.

A convenient switching valve includes a main body, a switching member and a positioning disc. The main body is provided with a water inlet and at least one water outlet. The positioning disc is rotatably fitted at an end of the main body. The positioning disc cooperates with the switching member, enabling the switching member to be moved in the main body to block a water passage between the water inlet and the water outlet. By rotating the positioning disc, the positioning disc movably press the switching member to block the water passage, thereby realizing the control of the water flow of the water outlet. The operation is convenient and labor-saving.

A fluid-ejection device includes a first member having a fluid inlet; a second member that can be moved relative to the first member; and a control member arranged to be at least in a first condition, in which the control member is at least substantially inside the second member during a first stroke of the second member in which fluid flow through the second member and discharge is prevented; and a second condition, in which the control member is at least substantially outside the second member during a second stroke of the second member, allowing fluid flow through the second member and discharge. A seal member has a first surface engaged with the first member, a second surface engaged with the second member, and a third surface arranged to be engaged with the control member in the first condition.

A water dispensing apparatus comprises a first tubular elongated element including a first inlet at a proximal end of the first tubular elongated element, an outlet at a distal end of the first tubular elongated element, and an uninterrupted first flow path extending from the inlet to the outlet for outputting a source of fluid to the outlet; a second tubular elongated element including a second inlet at a proximal end of the second tubular elongated element, a second flow path extending along a length of the second tubular elongated element from the inlet in the longitudinal direction, and a plurality of outlets along the length of the second tubular elongated element for outputting a source of fluid; a nozzle coupled to the outlet of the first tubular elongated element; and a control valve system coupled to each of the first and second inlets.

Various aspects include devices, systems, and methods for cooling electronic equipment immersed in an immersion coolant tank with a fluid delivery wand. The fluid delivery wand may include a coolant conduit and an aperture cover. The coolant conduit may extend from a support base of the immersion coolant tank. The coolant conduit may include a lumen configured to receive dielectric fluid, wherein the coolant conduit includes at least one conduit aperture extending through a sidewall of the coolant conduit. The aperture cover may be in sliding engagement with an outer surface of the sidewall of the coolant conduit. The aperture cover may be configured to selectively restrict flow of dielectric fluid through the at least one conduit aperture by sliding along the outer surface of the outer of the sidewall.

A water delivery device includes an inlet connector, a sprayface assembly, and a selection engine. The inlet connector is configured to couple the water delivery device to a water supply. The sprayface assembly includes a plurality of nozzles that are configured to produce a plurality of spray patterns. The selection engine fluidly couples the inlet connector to the sprayface assembly and controls flow to each one of the plurality of nozzles to determine the spray pattern produced at the sprayface assembly. The selection engine is configured to switch directly from any one of the plurality of spray patterns to any other one of the plurality of spray patterns in response to a single actuation of the selection engine.

A concealed top cover-type shower head, the shower head comprises a shower head body; an inlet base; a water diversion mechanism, the relative rotation of the water diversion mechanism and the inlet base makes the plurality of diversion waterways switched to connect to the water inlet holes, each set of which are annularly arranged with intervals and respectively connected to the diversion waterways; and a decorative cover, which is covered part or whole of the top cover and is rotatably assembled to the shower head body, the external periphery of the decorative cover and the external periphery of the inlet base are fixed together by an assembly component, the decorative cover is disposed with large throughout holes, the relative rotation of the decorative cover and the top cover makes the plurality sets of the outlet nozzles switched to correspond to the large throughout holes.
