detailed description

Refer to Figure 1 to Figure 6. A waterfall faucet includes a casing 1 in which a faucet body 2 is disposed. Here, as a preferred embodiment, the casing 1 is composed of a zinc alloy upper cover 12 and a zinc alloy lower cover 13 which are assembled. The zinc alloy upper cover 12 and the zinc alloy lower cover 13 are fixedly connected by a plurality of bolts 14. The front end of the casing 1 is provided with an elongated opening 10 for water to flow out, and the elongated opening 10 is preferentially opened on the zinc alloy. The front end surface of the cover 12 is formed by the faucet upper cover 21 and the faucet lower cover 22, and the front end portion of the faucet lower cover 22 is provided with a flat long water outlet 20, and the water outlet 20 is as described above. The elongated opening 10 is connected to the rear, and the rear portion of the faucet lower cover 22 is provided with a cavity 23 for storing water. The front and rear side walls of the cavity 23 are respectively provided with a gap 24 for water supply and flow, and water is supplied to the outside. The inlet through hole 25 is connected to the pipe. Here, the cavity 23 is preferentially processed into a horizontally symmetrical cavity, and the inlet through hole 25 and the notch 24 are preferentially opened on the horizontal symmetry center of the cavity; The water inlet through hole 25 is provided directly in front of the water inlet hole 25 Flowing and blocking the shunt block 26 of the notch 24, the diverting block 26 is located between the water inlet through hole 25 and the notch 24, and a gap between the water supply pipe and the inner wall of the cavity 23 is left. The shape of the above-mentioned shunt block 26 is preferentially processed into an isosceles triangle, and the top of the isosceles triangle is a smoothly transitioning arc, and the ends of the arc are respectively tangent to the two equilateral sides of the isosceles triangle, the isosceles The top of the triangle faces the inlet through hole 25, the bottom of which faces the notch 24, and when water comes in from the inlet through hole 25, it encounters the top of the isosceles triangle and is shunted because of the isosceles triangle The top is a smooth arc, so the water will not sound when it enters the top. After the water is diverted, it will accelerate along the two equal sides of the isosceles triangle into the left and right sides of the cavity 23, and then enter the water. Flowing from the gap between the bottom of the isosceles triangle and the inner wall of the cavity 23 to the gap 24, and then out of the gap 24, where the notch 24 is located and/or adjacent There is one or more rows of deceleration splitter columns 27, which are preferentially reduced here. The number of rows of the speed splitter column 27 is set to two rows, the first row of the speed reducing splitter column 27 is evenly distributed at the position where the notch 24 is located, and the second row of the speed reducing splitter column 27 is evenly distributed at the front side of the notch 24. Wherein, the above-mentioned deceleration splitter column 27 has a large cylinder with a diameter larger than the diameter of the other cylinders, and the other deceleration splitter columns are preferentially processed into a cylinder of uniform diameter, and the large cylinder is located at a row near the water outlet 20 to decelerate. At the middle position of the splitter column 27, that is, the large cylinder is located at the middle position of the second row of the speed reducing splitter column 27, and immediately after being discharged from the notch 24, the water is immediately decelerated by the splitter column 27. Deceleration and splitting, reducing the flow rate of water, can effectively avoid the sound of water flowing in the process of rapid flow, and at the same time, by dividing it, the flow area of the influent water is larger, so the inflow of water can fill the entire flow channel when flowing forward, and then The influent water then flows from the water outlet 20 to the elongated opening 10 because the inlet water is limited by the shape of the water outlet 20 and the elongated opening 10, so that the incoming water flows out of the elongated opening 10 in a strip shape. Free drawn down, a waterfall-like flow.

Further, an arcuate slope 28 that is upwardly arched is disposed between the second row of the deceleration diverter column 27 and the water outlet 20, and the arcuate slope surface 28 is fixedly disposed on the faucet lower cover 22, and the inflow water flows through the deceleration and diversion After the column 27, the block on the rear side of the curved slope 28 is encountered, causing the water level to rise continuously, the influent water gradually flowing over the top of the curved slope 28, and then the water enters from the top of the curved slope 28 from top to bottom. The flow is accelerated, so that the influent water recovers a certain flow rate, so that when the inflow of water from the elongated opening 10 is ensured, the water can continue to move forward for a short distance and then hang down, thereby making the appearance of the waterfall water bloom more beautiful.

Further, in order to prevent the inflow of water from flowing downward from the top of the curved slope 28, the sound is loud due to the excessive drop, and the front side of the curved slope 28 is provided with a downward convexity and is fixed on the faucet. The protrusion 210 at the front end of the bottom of the cover 21 forms a gap 280 of uniform width between the protrusion 210 and the curved slope surface 28, and the gap 280 can make the water inlet only along the curved slope surface 28. The front slope accelerates downwards, and does not slam down from the top of the slope directly to the bottom of the slope to make a sound, ensuring a silent effect.

Further, the water outlet 20 is provided with a slope surface 201 whose height gradually increases from the back to the front, and the slope surface 201 is preferentially processed into a straight slope surface with a front height and a low height, since the water inlet is from the slope surface 201. When the lower part moves upwards, it can flow out from the water outlet 20, so when the waterfall faucet is closed, the water still on the slope surface 201 flows backward due to gravity, and will not flow out from the water outlet 20 again. The waterfall faucet of the present invention can stop the water discharge immediately.

Further, a sealing groove 220 is defined in the upper end surface of the faucet lower cover 22, and a sealing ring 4 for preventing leakage of water between the faucet upper cover 21 and the faucet lower cover 22 is disposed in the sealing groove 220. The sealing ring 4 described above is preferably selected as a rubber ring or a silicone ring.

Further, the front end surface of the faucet upper cover 21 and the front end surface of the faucet lower cover 22 are respectively provided with an upper sealing groove 211 and a lower sealing groove 221, and the upper sealing groove 211 and the lower sealing groove 221 can be covered on the faucet 21 and the faucet lower cover 22 are combined to form a complete annular groove, the annular groove is surrounded by the outer circumference of the water outlet 20, and an annular sealing ring 5 is disposed between the front end surface of the faucet body 2 and the inner wall of the casing 1. The annular sealing ring 5 is installed in the annular groove, and the annular sealing ring 5 can ensure that the water flowing out from the water outlet 20 directly flows out from the elongated opening 10 without entering the casing 1. A casing 1 made of a zinc alloy is prevented from being infiltrated by water.

Further, at the peripheral edge of the faucet body 2, a plurality of elliptical pin holes 6 are formed through which the bolts 14 can pass, and the elliptical pin holes 6 and the bolts 14 are gap-fitted, and the bolts 14 can be The elliptical pin hole 6 moves to the left and right. When assembling, the faucet body 2 is first mounted on the zinc alloy upper cover 12, and then the zinc alloy lower cover 13 is covered and screwed into the bolt 14. At this time, the zinc alloy upper cover 12 and the zinc alloy are assembled. The lower cover 13 remains loose between the lower cover 13, and then the faucet body 2 is then moved forwardly near the inner wall of the front end face of the zinc alloy upper cover 12, thereby placing an annular seal ring between the front end face of the faucet body 2 and the inner wall of the casing 1. 5 is pressed, so that the annular seal ring 5 can better prevent the influent water from flowing into the casing 1 from the water outlet 20 of the faucet body 2, ensuring the sealing performance of the present invention, and finally tightening the bolt 14, not only can The zinc alloy upper cover 12 and the zinc alloy lower cover 13 are not loosened, and the faucet body 2 can be tightly sandwiched between them to ensure that the faucet body 2 and the casing 1 do not move relative to each other.
