The spring member (7) is held swingably with respect to the main body portion (3), and, in response to the operating lever (6) being pulled, the spring member (7) undergoes elastic deformation and swings with respect to the main body portion (3).

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.

There is provided a loop flow type bubble generation nozzle capable of improving the bubble generation efficiency compared to conventional nozzles without reducing the bubble generation efficiency even when liquid containing impurities is used. A loop flow type bubble generation nozzle 10 includes a tubular bottomed member 1 having a circular cross section and a tubular member 2 which is fitted into the other end side of the bottomed member 1. A substantially cylindrical space surrounded by the bottomed member 1 and the tubular member 2 serves as a loop flow type gas-liquid stirring and mixing chamber 6. The tubular member 2 has, on the center thereof, an inflow hole 7 which is capable of allowing liquid and gas to flow therein, and a first jet hole 8a and a second jet hole 8b which are capable of jetting liquid and gas. The inflow hole 7 is formed in a tapered shape whose diameter continuously expands from the first jet hole 8a toward the loop flow type gas-liquid stirring and mixing chamber 6. A plurality of cut-away parts 7a are formed on an end face of the inflow hole 7, the end face facing the loop flow type gas-liquid stirring and mixing chamber 6.

A pressure washer spray gun includes a spray gun body configured to be fluidly coupled to a source of pressurized water, a chemical container configured to contain liquid chemical, a chemical injection port fluidly coupled to the chemical container, an air inlet port configured to be fluidly coupled a source of air, and a nozzle configured for ejecting fluid through an orifice having an orifice diameter. The air inlet port is located between the chemical injection port and the nozzle orifice. In operation, with the orifice diameter being a first orifice diameter, a high pressure operating mode is implemented. In operation, with the orifice diameter being a second orifice diameter greater than the first orifice diameter, a chemical injection operating mode is implemented. In operation, with the orifice diameter being a third orifice diameter greater than the second orifice diameter, a foaming chemical injection mode is implemented.

A sanitary coupling (1) is provided that connects an inflow-side and an outflow-side line section to each other. A sanitary insert element (5) is provided that has an insert housing (4) and is insertable via an end-side insert opening into a housing receptacle (7) of a first line section (2). The housing interior (6) of the insert housing (4) communicates with the ambient air, in that an annular zone (10) is provided between the housing outer circumference of the insert housing (4) and the inner circumference of the housing receptacle (7), and in a partial region of said annular zone (10), at least one air duct (12) which is effective between housing interior (6) and housing outer circumference is provided. The first line section (2) has at least one air slot (13) which is open toward the end circumferential edge (9) and towards the inner circumference and towards the outer circumference of the first line section (2), and in the partial region of the annular zone (10) that is arranged between the annular flange (8) and the at least one annular seal (11), an air gap (14) is arranged between the housing outer circumference and the inner circumference of the housing receptacle (7), which air gap connects the air duct (12) to the air slot (13).

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 sliding member slidably coupled with the faucet head to enable a user to operate the control valve within the water valve by operating the sliding member from a side of the faucet head.

A dispenser main body (11) includes a cylindrical-shaped fitted portion (16a), and a nozzle (40) includes: a nozzle main body (41) and a nozzle extension body (42). The nozzle (40) is provided with a dispensing tube (51) including: a first dispensing tubular portion (51a) and a cylindrical-shaped second dispensing tubular portion (51b). A cut-out (52a) is provided in the front end of the first dispensing tubular portion (51a) or in a base end of the second dispensing tubular portion (51b), and an opening end of the cut-out (52a) is closed by the first dispensing tubular portion (51a) or the second dispensing tubular portion (51b) to provide an air inlet hole (52) in the dispensing tube (51).

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 control member movably coupled with the faucet head to enable operating the control valve within the water valve by operating the control member from or near a side of the faucet head.

Provided are showerheads with aeration that include a showerhead body comprising a front showerhead face comprising a plurality of nozzles and a rear showerhead face opposite the front showerhead face, a air/water mixing chamber located in an interior space of the showerhead body, a ventilation disk comprising a plurality of openings positioned between the front showerhead face and the rear showerhead face, and an actuating mechanism on the rear showerhead face. The actuating mechanism is configured to, when actuated, expose the plurality of openings of the ventilation disk to draw air through the plurality of openings and into the air/water mixing chamber to mix the air with water to form aerated water, and the plurality of nozzles in the front showerhead face are configured to receive the aerated water from the air/water mixing chamber and dispense the aerated water.
