A sanitary fitted element (1) which can be inserted into the water outlet of a sanitary outlet fitting and is held releasably there. A characteristic feature of the fitted element (1) according to the invention is that said fitted element has an adjusting device for changing the clear sectional area of flow of the fitted element (1) and/or the discharge rate, which adjusting device is actuable via at least one control element (8) which is arranged actuably on the inflow side of the fitted element (1) and/or on the outflow side thereof. The fitted element (1) according to the invention can be used in a versatile manner in order to reduce the outlay on production and stock.

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).

Proposed is an air mixing nozzle tip structure which improves productivity while simplifying the structure by being configured so that air is introduced through an air mixing inlet and discharged together with wash water, improves cleaning power while realizing a massage effect because fine water droplets are formed in the process that wash water and air are combined and discharged, controls the inlet amount of air by forming the air mixing inlet on one side or each of opposite sides of a nozzle tip cover or by adjusting the cross-sectional size of the air mixing inlet, and promotes product stability by providing an air supply passage at the rear of the air mixing inlet so that the air introduced through the air mixing inlet is smoothly discharged to a wash water ejection hole through an air guide.

The present disclosure provides an aerosol unit for an aerosol dispenser. The aerosol unit includes an axially oriented body, having a distal inlet part and a proximal outlet part. The aerosol unit also includes a carrier member arranged in the body, transversally to the axis between the inlet part and the outlet part. The carrier member includes through-holes which place the inlet part in fluid communication with the outlet part, and the carrier member is insert-moulded into the body such that a contact surface between the carrier and the body forms an air-tight seal.

A shower head to jet an air bubble-liquid mixture by mixing air bubbles into the liquid includes a shower nozzle, a flow-adjustment piece, and air introduction passages. The shower nozzle includes an air bubble mixing space. The flow-adjustment piece is arranged in the air bubble mixing space. The air introduction passages cause air to flow into the air bubble mixing space therethrough.

A microbubble treatment agent cartridge assembly and washing equipment having the microbubble treatment agent cartridge assembly. The microbubble treatment agent cartridge assembly includes a housing and a treatment agent cartridge accommodated in the housing. The housing is provided with at least one water inlet pipe portion. The at least one water inlet pipe portion is provided internally with at least one stage of diameter-decreasing tapered portion and a microbubble former, and the pipe wall thereof is further provided with an air inlet hole. The air inlet hole is positioned between the at least one stage of diameter-decreasing tapered portion and the microbubble former, and communicates with an air inlet pipe disposed on the housing. The top of the most downstream stage of diameter-decreasing tapered portion is provided with a spray hole. The spray hole enables the water flow flowing through the at least one stage of diameter-decreasing tapered portion.

The preset disclosure relates to a dishwasher. The dishwasher includes: a tub defining a washing space; a sump disposed below the tub and configured to store wash water therein; a pump configured to supply the wash water stored in the sump to the tub; and a spray arm configured to supply wash water flowing from the pump to the washing space. The spray arm includes: a spray blade configured to spray wash water into the washing space; a bubble generator having therein a bubble generation flow path of a venturi tube shape and configured to supply wash water containing a microbubble to the washing space; and a hub configured to supply wash water discharged from the pump to the spray blade or the bubble generator. The spray arm sprays wash water through the spray blade while simultaneously generating a microbubble through the bubble generator.

A liquid saving device includes a liquid guide and a vortex adaptor. The liquid guide includes a primary recess, an indentation, and a plurality of primary pores. The vortex adaptor includes at least one air inlet structure, a trench, a gap and a center through hole. The plurality of primary pores is coupled to the indentation for receiving a first liquid stream to generate a same plurality of second liquid streams at respective ends. At least part of the plurality of primary pores have different lengths. A primary pore has a shorter length if the first primary pore outputs its corresponding second liquid stream with a larger deflection, and vice versa. The trench receives both at least one secondary liquid stream and air to generate a first aerated vortex. An elevated flow of the first aerated vortex with a spray-form liquid stream to generate a second aerated vortex.

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.

Disclosed is an aerator with dual spraying functions, including a flow control assembly, a water separator, and a water dispenser that are combined with a housing. The flow control assembly and the water separator are combined together and the water separator and the water dispenser are rotatably connected to each other. The water separator has a surface in which discharge holes are formed. The water dispenser has an internal chamber having a circumferential portion in which needle-like water channels are formed to correspond to the water separator. Bubbling water passages are formed between the needle-like water channels and a central portion surrounded by the needle-like water channels defines a bubbling water channel.
