In an outflow structure (10) of a jet regulator (1), holes (17, 19, 25) are formed in the edge region of a regular arrangement (12) which are enlarged with respect to the regular arrangement (12), in order to avoid the formation of small holes (17, 19, 25) in the edge region.

A device for limiting or keeping constant a quantity of fluid flowing therethrough, includes: a housing with a front chamber and a rear chamber; a partition arranged in the housing with two or more openings; and a flow limiting element arranged in one or both openings. The flow limiting element includes a housing provided with an inlet, an outlet and a throughflow opening; and a resilient plate-like valve element mounted in the housing, substantially able to close the throughflow opening by resilient movement in the direction of a valve seat arranged in the housing adjacently of the throughflow opening. The valve element is fixed on one side and can move resiliently on the opposite side in the direction of the valve seat. A mould produces one or more injection-moulded products. The injection-moulded product is a flow limiter for limiting the force of the flow of a fluid flowing therethrough.

In the case of a hose connector assembly (1) it is provided for a retaining plate (15) to be used for axially fixing at least two hoses (6, 7, 8) in corresponding hose receptacles (3, 4, 5). The hoses (6, 7, 8) are insertable into respective recesses (16, 17, 18) of the retaining plate (15) by way of a lateral insertion movement (19), and the hoses (6, 7, 8) engage behind the recesses (16, 17, 18).

A kitchen shower includes a water outlet mechanism, a switching mechanism and a brush mechanism. The water outlet mechanism is provided with a shower water outlet, a sheet water outlet and a bubble water outlet. The switching mechanism includes a main body, a first switching assembly, a second switching assembly and a third switching component. The first switching assembly is used to switch whether the kitchen shower is out of water, the second switching assembly is used to switch the kitchen shower out of sheet water, and the second switching assembly is used to switch the kitchen shower out of shower water or bubble water. The brush mechanism is detachable and installed on the water outlet mechanism. The brush mechanism can make the kitchen shower clean at the same time of water outlet, so that the cleaning effect is higher.

In an aerator (101, 104, 107, 110, 112), the housing (2) and insertion parts (7, 8) that can be inserted into the aerator have complementary tooth arrangements which mesh with each other when the aerator is assembled such that the housing (2) and the insertion parts (7, 8) are rotationally locked relative to each other.

The invention relates to the field of bath products, and provides a flow control device. The flow control device comprises a movable rod capable of reciprocating to switch water into different outlet passages, wherein a flow control part circumferentially extends and protrudes out of the movable rod, and the movable rod rotates to drive the flow control part to rotate to control the flow in the corresponding outlet passage. During use, the movable rod is pressed to control the switching the outlet passages, and users can select the position where water is discharged as required, for example, water is discharged upwards or downwards. Moreover, the movable rod rotates to drive the flow control part to rotate to flexibly control the flow of a certain outlet, such as the upward outlet flow, to facilitate daily washing of the users.

A device that serves to increase the pressure on the outlets of water intakes in houses or gardens. This system to increase the water pressure is called salt-cellar-like device for increasing pressure. The salt-cellar-like device for increasing pressure has 6 external walls that give its body a hexagonal shape. These external walls allow the device to be held firmly by some tool that rotates the device, so that it is correctly inserted and attached to some water intake. The salt-cellar-like device for increasing pressure has a head that has a circular concavity on its upper part, as well as on the surface of this circular concavity there is an arrangement of conduits from which the water leaves the device to a higher pressure.

A faucet outlet screen filter, for solving problems that a water outlet flow rate of faucets is too large and even water splashes out from a water pool, includes a metal mesh having a plurality of layers. The metal mesh is formed by criss-crossingly connecting a plurality of metal wires. Mesh holes of each of the plurality of the layers of the metal mesh are staggered with each other. The metal mesh includes a plurality of side walls, a bottom wall, and open space regions, where the open space regions are defined between the plurality of the side walls and the bottom wall. Water flows into a faucet through an opening of the open space regions and flows out of the faucet after being filtered by the bottom wall.
