A tamper-resistant aerator including an aerator cartridge, an insert defining at least one removal slot, and a locking ring defining at least one removal slot at least partially disposed within a housing is disclosed. The locking ring rotates with respect to the housing to allow alignment of the removal slot of the locking ring with the removal slot of the insert. Alignment of the slots form a continuous passageway through the locking ring and into the insert. Alternatively, a plurality of removal slots may be provided. A mating engagement between the locking ring and the housing secures the locking ring within the housing while still allowing it to rotate with respect to the housing. An aerator system is also provided comprising an aerator as described above and a tool adapted to be received in the continuous passageway formed by the alignment of the slots and engage the insert.

The invention relates to a sanitary functional unit (2), which has a housing (6), which can be releasably fastened to the water outlet of a sanitary outlet fitting, the housing (6) having an outflow-side housing end face (9) with outflow openings (10). It is characterizing for the functional unit according to the invention that the outflow-side housing end face (9) has at least one slot (19), the opposing longitudinal sides (20) of which slot are designed as turning engagement surfaces or tool engagement surfaces for a turning tool that can be releasably inserted into the at least one slot (19) and is preferably formed as a coin (21), and that the housing (6) of the functional unit (2) is rotatably held on the water outlet of the outlet fitting and/or the housing end face is mounted rotatably in relation to the housing on said housing. With the assistance of the slot (19) provided on the housing end face (9) and the assigned turning tool, it is possible, for example, for a housing end face (9) that is pivotably mounted in the housing to be easily aligned and/or for the turning force that is required for fitting and removing a screw connection provided between the outer housing periphery and the inner fitting periphery to be conveniently transferred to the housing (6) without special turning tools being necessary.

A trigger-type liquid ejector which includes an ejector main body and a nozzle member in which an ejection hole is formed, the ejector main body including a vertical supply tubular pipe, an injection tubular portion, and a trigger mechanism, the nozzle member including a nozzle main body and a valve body, the nozzle main body including a valve seat portion having a valve seat plate, an inside of the valve seat plate communicating with the ejection hole, the nozzle main body including a tubular foam-forming portion positioned in a front of the ejection hole and configured to surround the ejection hole, and the foam-forming portion is provided with an outside air introduction hole penetrating through the foam-forming portion in a radial direction thereof.

Provided is a water discharge device for spraying water having transparency throughout a long distance. The present invention is a water discharge device (2) that sprays the supplied water, and includes a water discharge device body (6), a rectifying chamber (14a) which is provided in the water discharge device body, a plurality of rectifying members (18) that are disposed at intervals in the rectifying chamber and includes a number of fine holes (18a), so that water sequentially passes through the plurality of rectifying members, a water spray member (20) provided with spray nozzles (22b) for discharging the water passing through these rectifying members, and an air bubble discharge flow path (26) that is formed so that air bubbles present among the rectifying members bypass at least one of the rectifying members to reach the water spray member, and has a larger flow path sectional area than the fine holes.

A spraying apparatus comprising a plurality of spray nozzle assemblies mounted along a liquid supply boom. The spray nozzle assemblies each include a one piece spray nozzle and retention cap (20) having an upstream cap section (21) and a downstream nozzle section (22) integral with the cap section. The cap section (21) is formed with internal camming and locking grooves (25) for drawing the cap section into mounted position on a liquid inlet stem (12) as an incident to rotation of the cap, and the nozzle section (22) has a liquid inlet passage (41) communicating with the inlet stem (12) for directing a discharging liquid spray. A pre-orifice insert (60) is mounted within the spray nozzle and retention cap (20) which has a smaller diameter nozzling passage section, and an intermediate section (24) of the one piece spray nozzle and retention cap (20) is formed with air passageways communicating between the pre-orifice liquid flow passage and outside ambient air.

An apparatus for creating solid or liquid nanoparticles having a nozzle to create a first particle size from a bulk liquid flow that is in fluid communication with a gas flow amplifier comprising an inlet cone connected to and in fluid communication with the inlet of a cylindrical housing; a diffuser connected to and in fluid communication with the outlet of said housing; and said housing comprising at least two rings of ports disposed of along a circumference of the cylindrical housing; and a means to inject compressed gas into the housing through said ports.

An all-plastic external foam pump, including an actuator, a fixing member, a plunger, an elastic member, a cylinder body, and a straw, is provided. One end of the fixing member is fixed or detachably connected to the actuator, and the other end is fixed or detachably connected to the plunger. The fixing member is at least partially accommodated in the cylinder body. One end of the plunger is penetrated into the elastic member. The straw is installed on one end of the cylinder body. A pulling rod is disposed in the plunger. The pulling rod is disposed in linkage with the plunger. The elastic member is made of a recyclable elastic material. A liquid mixing portion is disposed in the fixing member.

A faucet having a faucet base, a water hose, a faucet head, and a chamber is provided. A water valve is provided in the chamber and includes a driving member and a control valve movable between a first position enabling mixing of water and air and a second position enabling shut-off of a water flow. The faucet head further includes a push-to-rotate member movably coupled with the faucet head to enable operating the control valve within the water valve by operating the push member from or near a side of the faucet head.
