摘要： 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.

摘要： A jet regulator (100) including a jet regulator housing (2) is disclosed, in the housing interior of which a perforated plate (5) is provided with a plurality of flow-through holes (6) for dividing the through-flowing water. The jet regulator described is characterised in that at least one flow-through hole (6) extends conically towards its outflow side in at least one outflow-side hole section. It is also possible for flow obstacles to be provided on the outflow side of the perforated plate (5) in the jet regulator housing (2) and/or on the outflow front face of the jet regulator housing, which are arranged or concentrated there in a central or middle region and which deflect the through-flowing water into an outer annular zone. This jet regulator (100) enables an aerated and thereby sparkling-soft water jet to be generated even with low flow-through performance and low water pressure.

摘要： The present invention relates to the fluid discharge device of a fluid transfer pipe, and to a technology which alters the sectional area of a discharge hole in proportion to the increase or decrease in fluid discharge flow per unit of time so as to maintain a relatively uniform fluid discharge rate from the discharge hole.

摘要： A flow-controlling unit having a function of limiting the tilting angle of a flow-controlling piece which includes a flow-controlling plate, which is disposed perpendicular to the moving direction of a fluid in a flow channel. The flow-controlling plate includes first fluid through-holes through which the fluid passes and flow-controlling pieces which are provided in a part corresponding to the first fluid through-holes. The flow-controlling pieces are inclined in the direction of the inflow of the fluid and control the degree of opening of the first fluid through-holes by being tilted due to pressure applied from hydraulic pressure of the fluid. A tilting-angle-limiting plate has second fluid through-holes which communicate with the first fluid through-holes, wherein the diameter of the second fluid through-holes is smaller than the diameter of the first fluid through-holes, allowing the flow-controlling pieces to be supported to limit the tilting angle of the flow-controlling pieces.

摘要： A flow regulator includes a housing portion, a diversion device, an annular seat and an elastic water stop ring. The annular seat, the diversion device and the housing portion are fixedly assembled together. The diversion device comprises a periphery wall disposed with diversion holes, a central base in the periphery wall and a deflecting annular wall fixedly connecting the periphery wall and the central base. The external periphery surface of the deflecting annular wall is gradually larger downwardly from the central base to the periphery wall. The central base has at least a part extending out of the internal hole of the annular seat. A flowing clearance is formed between the central base and the hole wall of the internal hole of the annular seat. The flowing clearance is disposed above the deflecting annular wall so that water flows out of the flowing clearance and onto the deflecting annular wall.

摘要： A jet regulator (1), having a perforated plate (5) arranged therein with throughflow holes (6) extending through the perforated plate for dividing the water flowing therethrough, including a central, non-perforated impingement surface (14) on the perforated plate (5), which non-perforated impingement surface is surrounded by a first annular wall (15), which has passage openings (16) that are oriented in a radial direction and extend through the first annular wall, wherein a respective throughflow hole (6), which extends through the perforated plate (5) and is connected to the respective passage opening (16), is provided on the side of each passage opening (16) arranged in the impingement surface plane. The annular wall (15) is surrounded by an annular ring chamber (29) on the outer circumferential side. A flow regulator (30) or a throttling device (300) is provided in front of the impingement surface (14) in the flow direction of the water, whereby the water consumption is restricted and/or the water flow rate becomes largely independent of the particular water pressure. Furthermore, a second annular wall (33), which has a smaller diameter than the first annular wall and is arranged at a distance from the first annular wall, is provided coaxially and concentrically to the first annular wall (15), which second annular wall has radial passage openings (34) arranged at a distance above the impingement surface (14), through which radial passage openings the water has access to the first annular wall (15) and to the passage openings (16) of the first annular wall and thus to the throughflow holes (6). Through this combination, the water flow rate through the jet regulator becomes practically independent of the water pressure upstream of the jet regulator (1).
