Description
Technical Field
[0001] The utility model relates to a bathtub faucet, in particular to a low-noise bathtub faucet. Background Art
[0002] A bathtub faucet is a faucet used in the bathroom. Different from ordinary faucets, a bathtub faucet not only has a spout, but also has a water outlet joint for connecting a handheld shower head. The bathtub faucet also has two water inlet joints, which are used to connect the hot water pipe and the cold water pipe respectively. As the bathtub faucet opens its valve core through the handle, the hot water in the hot water pipe and the cold water in the cold water pipe both enter the valve core for mixing, and flow into the water outlet cavity in the faucet body through the water delivery channel connected to the valve core. The spout and water outlet joint of the bathtub faucet are both connected to the water outlet cavity, and finally the water flows out through the spout or the water outlet joint for use.
[0003] The water outlet cavity of a traditional bathtub faucet does not have any buffer structure and has a large space. The air inside the water outlet cavity is extremely difficult to exhaust. Therefore, it is very easy for the fast-flowing water to squeeze the air inside the water outlet cavity. When the air is squeezed by the fast-flowing water, it is very easy to produce a whistling sound, thereby forming noise. At the same time, the fast-flowing water will form a large impact force without any buffer. When the faucet and the water outlet joint are perpendicular to the water outlet cavity, the water will flow through the faucet and the water outlet joint and continuously hit the inner wall of the water outlet cavity. Frequent collisions will also increase the sound when the bathtub faucet is discharging water. Summary of the invention

[0027] A rotary handle 43 is disposed at the center of the upper surface of the cover plate 39 .
[0028] An annular positioning groove 44 is provided on the inner wall of the lower end of the connecting hole 35 ; a positioning portion 45 matching the positioning groove 44 is provided on the upper portion of the water nozzle 8 .
[0029] The method of using the utility model is as follows:
[0030] When the user opens the valve core 4 through the handle 5, the cold water and hot water entering from the two water inlet joints will mix and flow into the water outlet chamber 6 through the water delivery channel 7. At this time, as the water flows into the water outlet chamber 6, it will be blocked by the water baffle 10 and the outer wall of the right side of the square tube 12. Therefore, the water flow can only rush to the rubber membrane 23 through the inner hole of the limit ring 22. At this time, the incision in the center of the rubber membrane 23 will be opened by the pressure of the water flow. As the rubber membrane 23 is deformed, the rubber membrane 23 will produce elasticity, which will effectively buffer the water pressure of the water flow and prevent the water flow from In the case where the flow rate is too fast and the air is squeezed, when the water flows into the square tube 12 through the incision 24 in the center of the rubber membrane 23 and the water inlet 19 in turn, it will be divided into two streams. One part of the water flows directly through the water hole 21 to the outside of the square tube 12, and the other part of the water flows upward under the guidance of the trajectory of the inner wall of the square tube 12, and then flows to the left through the water gap 13 between the upper end face of the square tube 12 and the upper inner wall of the water outlet chamber 6. Under the obstruction of the outer wall of the buffer seat 36 and the cover plate 39, the water can only flow into the buffer groove 37 through the water diversion hole 38.
[0031] When the water flows into the buffer groove 37, it will directly impact the right side wall of the upper baffle 41, and the lower end of the upper baffle 41 is tilted to the right. Under the guidance of the right side wall of the upper baffle 41, the water flow rate is suppressed again, and then the water flows through the gap between the lower end surface of the upper baffle 41 and the bottom of the buffer groove 37 into the space between the upper baffle 41 and the lower baffle 42, and the water flow between the upper baffle 41 and the lower baffle 42 will flow upward, and then flow to the left through the gap between the upper end surface of the upper baffle 41 and the lower surface of the cover plate 39, and then flow downward, and finally flow into the water nozzle 8 through the water diversion hole 38, and flow out of the water nozzle 8 for use.
[0032] When the sealing plate 18 covers and seals the upper end port of the water outlet joint 9, the water nozzle 8 is in a water outlet state, and the water outlet joint 9 does not discharge water. When water is needed to be supplied to the hand-held shower connected to the water outlet joint 9, the telescopic column 15 can be pulled upward by the pulling head 16. As the telescopic column 15 moves upward, the telescopic column 15 will pull the sealing plate 18 upward through the pull rod 17. As the sealing plate 18 continues to move upward, the sealing plate 18 will eventually be above the water inlet hole 19. At the same time, the outer peripheral surface of the sealing plate 18 covers and seals the inner end opening of the water through hole 21. The water flowing into the square tube 12 through the water inlet hole 19 can only flow to the water outlet joint 9, and then it will flow into the hand-held shower connected to the water outlet joint 9 through the water outlet joint 9 for use. When the water flow continues to flow into the square tube 12, the inside of the square tube 12 will be filled with water, and the sealing plate 18 is always suspended in the upper space of the square tube 12.
[0033] From the above, it can be seen that the present invention can not only buffer the water flow through the elasticity of the rubber membrane 23 to avoid the situation where the water flow rate is too fast and causes the air to be squeezed to produce a whistling sound, but also change the flow trajectory of the water flow through the position distribution of the water inlet hole 19, the upper end pipe mouth of the square tube 12, and the water hole 21 to avoid the situation where the water flow is too fast due to direct flow, ensure that the water flow has enough time to fill the water outlet chamber 6, and discharge the excess air in the water outlet chamber 6 to the outside, avoid the situation where there is air residue in the water outlet chamber 6 causing noise when the water flows, and at the same time, it can avoid the situation where the direct flow of water causes frequent impact on the inner wall of the water outlet chamber 6 to cause noise, thereby achieving a low noise effect and avoiding noise pollution and noise causing discomfort to users.
[0034] An annular screw groove 25 is provided on the inner wall of the upper end of the square tube 12, and a retaining ring 26 is screwed in the screw groove 25 and is arranged on the outside of the pull rod 17. There is a water outlet gap 27 between the inner wall of the retaining ring 26 and the outer wall of the pull rod 17. The retaining ring 26 can effectively limit the upward movement of the sealing plate 18, thereby avoiding the situation in which the sealing plate 18 is passively moved upward when the water flow impacts the lower surface of the sealing plate 18, and can also play a positioning effect, thereby ensuring that the sealing plate 18 can accurately seal the inner end opening of the water hole 21.
[0035] The outer wall of the sealing plate 18 is provided with a U-shaped sealing groove 28 , and a matching sealing ring 29 is provided in the sealing groove 28 . The presence of the sealing ring 29 can effectively improve the sealing between the outer wall of the sealing plate 18 and the inner wall of the square tube 12 .
[0036] A screw hole 30 is provided at the center of the upper surface of the sealing plate 18, and a screw joint 31 screwed to the screw hole 30 is provided at the center of the lower end surface of the pull rod 17. This fixing method facilitates the disassembly and assembly between the sealing plate 18 and the pull rod 17, thereby facilitating the disassembly and assembly of other components.
[0037] A square hole 32 matching the square tube 12 is provided on the lower surface of the faucet body 1, and symmetrical fixing wings 33 are provided on the left and right outer walls of the lower end of the square tube 12. The fixing wings 33 are fixed to the faucet body 1 by screws 34. This fixing method can not only ensure the stability of the square tube 12, but also ensure the accuracy of the installation position of the square tube 12.
[0038] A rotation handle 43 is provided at the center of the upper surface of the cover plate 39 . The existence of the rotation handle 43 facilitates the rotation of the cover plate 39 and facilitates the disassembly and assembly of the cover plate 39 .
[0039] A ring-shaped positioning groove 44 is provided on the inner wall of the lower end of the connecting hole 35, and a positioning portion 45 matching the positioning groove 44 is provided on the upper part of the water nozzle 8. The presence of the positioning portion 45 can effectively prevent the upper end of the water nozzle 8 from being too deep into the water outlet cavity 6 when it is screwed into the connecting hole 35.
