A part includes a base material and a surface layer on the base material, wherein a curved surface of the part has: a root mean square height (Sq) of 0.03 μm to 1 μm, a skewness (Ssk) of −1 to 5, and an autocorrelation length (Sal) of 10 μm to 65 μm; and the surface layer is water-repellent, and exhibits a sputtering time of 5 minutes or less, the sputtering time being a time taken from the start of the sputtering to an end point of the surface layer, and the end point being defined, in a profile obtained by an XPS depth direction analysis of the surface layer, as a point where a difference of an absolute value between a carbon atom concentration at a certain measurement point and a carbon atom concentration at a measurement point just prior to the certain measurement point is 1.0 at % or less.

A faucet cleaning assembly includes a pouch which has an inner layer and an outer layer. The inner layer is comprised of a fluid impermeable material defining an interior of the pouch thereby facilitating the interior of the pouch to contain an acidic solution. The pouch is positionable around a faucet thereby facilitating the acidic solution to dissolve mineral deposits on the faucet. A band is integrated into the pouch and a drawstring is integrated into the band. The band is collapsible when the drawstring is tightened for retaining the pouch on the faucet. A lock is slidably disposed on the drawstring to retain the drawstring in a tightened condition for retaining the band around the faucet.

The showerhead has a hollow body (10) provided with an inlet nozzle (11) and with a sieve (C) perforated by holes (13) and a cleaning device (40) carrying a plurality of lower pins (41) and displaceable, in the interior of the hollow body (10), between an inoperative position, with the pins (41) spaced from the sieve (C), and an operative position, with each pin (41) introduced into one hole (13) of the sieve (C) and defining at least one water outlet with the hole (13). A driving element (50) is associated with the inlet nozzle (11) and is affixed to the cleaning device (40), in order to maintain it in the inoperative position, while the hydraulic pressure in the inlet nozzle (11) is less than a reference value and displacing the cleaning device (40) to the operative position, when the hydraulic pressure reaches the reference value. A biasing element (60) displaces the driving element (50) and the cleaning means (40) to the inoperative position, when the hydraulic pressure is lower than the reference value.

The invention relates to a jet regulator (1) having an annular or sleeve-shaped jet regulator housing (2), on the outlet end side of which there is held an outlet disc (3) which can be inserted into the jet regulator housing (2), which (3) has a perforated, grid and/or mesh structure with throughflow openings (5), wherein the outlet disc (3) bears a manually deformable dimensionally elastic plastics lining (4), and wherein the plastics lining (4) is of pot-shaped design. In order to reduce the production expenditure, it is provided according to the invention that the plastics lining (4), with an upwardly drawn circumferential wall (16) of its pot shape, provides sealing between the outer circumference of the outlet disc (3) and the housing inner circumference of the jet regulator housing (2).

A shower jet generating device for a shower head, illustratively for a sanitary shower head, including a shower jet disk delimiting a fluid chamber on an outlet side and including at least one jet outlet opening leading out of the fluid chamber and at least one overpressure valve opening, and comprising at least one overpressure valve disposed on the overpressure valve opening. The overpressure valve illustratively includes an overpressure outlet opening leading out of the fluid chamber, an immobile valve seat and a valve body capable of movement controlled by a fluid pressure in the fluid chamber and interacting with the valve seat, which valve body, in a normal pressure position, rests against the valve seat, thereby closing the overpressure outlet opening, and, in an overpressure position, is lifted off the valve seat, thereby exposing the overpressure outlet opening.

A suction nozzle for a hard-surface suction appliance includes a base body including a suction surface to which a suction channel is connected. A suction unit can be connected on a first side of the base body which is remote from the suction surface in order to form a suction flow. The base body further includes a bottom wall, a top wall, and first and second side walls. The base body is divided into suction chambers by at least first and second partition walls.

A faucet cleaning system provides a water dissolvable applicator formed from a thin sheet material which is stretchable and shaped to define a sleeve configured to encapsulate a faucet head. A cleaning agent is contained within the applicator via a water dissolvable film and is configured to release upon contact with moisture on the faucet head.

A faucet cleaning device has a bag having an inside area, a sponge, a cleaning agent and an adhesive. The sponge is located inside the bag and a cleaning agent is located inside the bag. The adhesive is attached to the bag. A faucet head is placed into the inside of the bag. The faucet cleaning device is attached to the faucet with the adhesive filling the bag with water from the faucet waiting a duration of time.

A part includes a base material and a surface layer thereon, wherein a curved surface of the part has a root mean square height (Sq) of 0.03 m to 1 m, a skewness (Ssk) of 1 to 5 or less, and an autocorrelation length (Sal) of 10 m to 65 m; and the surface layer is water-repellent, and exhibits a sputtering time of 5 minutes or less, the sputtering time being a time taken from the start of the sputtering to an end point of the surface layer, and the end point being defined, in a profile obtained by an XPS depth direction analysis of the surface layer, as a point where a difference of an absolute value between a carbon atom concentration at a certain measurement point and a carbon atom concentration at a measurement point just prior to the certain measurement point is 1.0 at % or less.
