A fluid injector includes a fluid inlet; a valve seat located downstream of the fluid inlet and having a valve seat aperture extending therethrough; a valve member moveable between a closed position and an open position to control flow through the valve seat aperture; and director plate including a first aperture and a second aperture extending therethrough. A fluid flow channel is formed between the valve seat and the director plate and extends from an inlet end to an outlet end. The first aperture and the second aperture extend through the director plate from the fluid flow channel. The first aperture is located between the inlet end and the second aperture. The fluid flow channel decreases in cross-sectional area from the inlet end toward the first aperture and the fluid flow channel increases in cross-sectional area from the first aperture toward the second aperture.

A jet regulator (104) including a jet regulator housing (1) having an outer thread (2) on the outer circumference of the housing for screwing into an internal thread (3) in the water outlet (4) of a sanitary outlet fitting. The jet regulator housing (1) has a thread profile as an outer thread (2) on the housing outer circumference, deviating at least in sections from a thread groove that is continuously spiraling around a cylindrical wall, which outer thread cooperates in this region in a self-adapting manner with the internal thread (3) provided in the water outlet (4) and/or has at least one cross-sectional widening (6, 7) which is made of the same material as the housing section of the jet regulator housing (1) supporting the outer thread (2) and which is integrally formed thereon, and which can be sealingly placed on the water outlet (4) on the end side and/or on the inner circumference side.

The present disclosure discloses a water outlet mechanism and a shower head comprising the water outlet mechanism. The water outlet mechanism comprises an inlet, an air intake chamber, an air intake passage, and a water outlet passage. The water outlet passage is in communication with the air intake chamber, and the air intake chamber is disposed with a wall connected to an entrance of the water outlet passage. The water outlet passage gradually increases in a downward direction, and a plurality of rectifying ribs protrude from an inner wall of the water outlet passage and are arranged in a circumferential direction at intervals. When the water flows through the inlet and enters the air intake chamber, a flowing cross sectional area of the water changes suddenly, an air pressure surrounding the water is less than the external air pressure, and a negative pressure is generated in the air intake chamber.

A flow self-adjusting faucet aerator includes an aerator unit. Upper and lower ends of the aerator unit have a water inlet and a water outlet, respectively. A flow regulator is fitted in the water inlet of the aerator unit. The flow regulator can automatically adjust the discharge area according to the change of the water pressure of the influent water flow to maintain the stability of the water outflow.

A foamed water discharging device includes a water feeding hole, a water discharging hole, a water passage, a ventilation passage, and a foamed water generator. The water passage has a cylindrical inner circumferential surface extending from the water feeding hole to the water discharging hole. The ventilation passage takes in external air on the upstream side of the water passage. The foamed water generator causes water containing the external air to undergo a collision on the downstream side of the water passage so as to convert the water into foamed water. The foamed water generator includes flow dividing ribs along the inner circumferential surface of the water passage, which protrude radially toward the center of the water passage. On a top portion of each flow dividing rib, at least a pair of inclined surfaces are formed to divide, rightward and leftward, water inflowing from a water guiding passage through the water feeding hole.

The present invention relates to a jet regulator (2) has a jet regulator housing with at least two housing parts (5, 6) which are rotatable relative to one another and of which an inflow-side first housing part (5) is mountable in a rotationally fixed manner on the water outlet of a sanitary outlet fitting and of which an outflow-side second housing part (6), at least at its outflow-side housing outer circumference, is configured as a handle or is connected to a handle, wherein the first housing part (5) has a jet splitter (7) having a plurality of splitter openings (8), wherein spaced-apart jet ducts (9) are provided on the housing inner circumference of the second housing part (6), and wherein the individual jets coming from the splitter openings (8) are guided through the jet ducts (9) and formed into an annularly circumferential outlet jet pattern in a first rotary position of the housing parts (5, 6), and are deflected in the housing interior of the jet regulator (2) to a central outlet opening (10) in the jet regulator housing in a second rotary position. The jet regulator according to the invention is characterized in that a rotary latch having at least one latching tooth (13) is provided, said latching tooth (13) being integrally formed on a duct wall facing the housing interior of the jet regulator housing and said latching tooth (13) interacting with a latching profile, and in that a lattice or grid structure that extends over the central outlet opening (10) is integrally formed on the outflow side of the second housing part (6).

The subject of the invention is a device for dispensing a cosmetic composition, said device comprising a dispensing head (1) intended to be fitted on a container containing said cosmetic composition to be dispensed, (i) the dispensing head comprising: a body (3) that is open at its two opposite axial ends, an engaging part (10) that is open at its two opposite axial ends and at least partially defines a dispensing orifice (12), and (ii) the cosmetic composition comprising, in a cosmetically acceptable medium, at least one cosmetic active agent, in particular at least one deodorant active agent and/or antiperspirant active agent, at least one C.sub.1 to C.sub.5 alcohol, at least one propellant,
the concentration of propellant being between 60% and 90% by weight with respect to the total weight of the pressurized composition.

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.

The present invention discloses a water outlet device, comprising: at least one rotatable driving member, at least one injector, and a main body with a plurality of water outflow passages. The main body comprises at least one accommodating cavity, each of the at least one rotatable driving member is driven to rotate by water flow, and each of the at least one rotatable driving member drives the corresponding one of the at least one injector to rotate in the corresponding one of the at least one accommodating cavity. Each of the at least one injector comprises at least one injection hole, the at least one injection hole is connected to the corresponding one of the plurality of water outflow passages, and a water outflow direction of the at least one injection hole and an axial direction of the corresponding one of the plurality of water outflow passage forms an angle.

A method for dispensing a sanitizing composition comprising a carrier fluid involves passing a carrier fluid under pressure through a nozzle and a chamber mounted to the nozzle. The chamber receives the carrier fluid from the nozzle and has an opening on an opposite side from the nozzle through which the carrier fluid exits the chamber. Ozone is provided to an interior of the chamber in the presence of the carrier fluid, and is irradiated with ultraviolet radiation as the carrier fluid and the ozone pass through an interior of the chamber.
