Description

Technical Field

[0001] The invention belongs to the technical field of valves, and in particular relates to an anti-drip water-saving valve. Background Art

[0002] A drip-proof water-saving valve, through a special structural design or intelligent control technology, effectively prevents residual dripping (leakage) after a pipe is closed, thus reducing water waste. Its core goal is to improve sealing and precisely control water flow, thereby achieving water conservation in daily life, agricultural irrigation, and industrial water use scenarios.

[0003] In the existing technology, one-way pressure-type faucets (such as push-type and lift-off faucets) are widely used in public places and homes due to their convenient operation and water-saving advantages. These faucets usually use spring return or magnetic suction structure to achieve automatic closing of the valve core, but in actual use, the following problems still exist: Relying on manual tightening, it is easy to cause leakage due to improper operation: Existing valves often rely on the user's pressure or lift to achieve a seal. If they are not completely closed, a small gap will form between the valve core and the sealing surface, causing continuous water leakage. Long-term leakage not only wastes water resources, but may also cause scale deposition, further exacerbating seal failure. Lack of gravity self-compensating closing mechanism for water leakage: The existing technology does not use the gravity of the leaking water as a power source to assist the valve in closing. When the valve is not closed tightly and water leaks, the leaking water droplets cannot be collected and converted into mechanical energy, and automatic tightening and sealing cannot be achieved. After long-term use, the friction resistance increases and the closing force is insufficient: Components like the valve handle's shaft and seals can experience increased friction due to scale deposits and material aging (e.g., rubber hardening and metal oxidation). In these cases, the restoring force of the existing spring or magnetic structure may not be sufficient to fully close the valve, requiring the user to apply greater pressure, otherwise leakage will continue. Therefore, a drip-proof, water-saving valve is needed. Summary of the Invention

Push-pull rods are rotatably connected to the side walls of the two sliding sleeves that are opposite to each other, and the other ends of the two push-pull rods are rotatably connected to the outside of the sleeve plate with the same vertical cross-section and a mouth-shaped structure, and the sleeve plate is movably sleeved on the outside of the lifting and pressing handle.

[0008] As a preferred embodiment, the inner wall of the sleeve is slidably connected to a pressure plate with an I-shaped cross-section, and both ends of the pressure plate are integrally formed with sliding parts with a convex cross-section. The two sliding parts are symmetrically arranged, and the sliding parts are both slidably connected to the sliding grooves opened on the inner wall of the sleeve.

[0009] As a preferred embodiment, a rubber pad is provided at the bottom end of the pressure plate, a hand screw is threadedly connected to the top center of the sleeve plate, and the bottom end of the hand screw is rotatably connected to the top center of the pressure plate.

[0010] As a preferred embodiment, the height-adjustable positioning assembly includes a sleeve with a U-shaped cross-section and an L-shaped vertical section fixed to the bottom end of the U-shaped bracket, and a plurality of equidistantly arranged alignment seats are fixed to both side walls of the sleeve, and the outer sides of the plurality of alignment seats on both sides and the outer side of the sleeve are movably sleeved with an exoskeleton with the same U-shaped cross-section, and a first weakening groove is provided at the two bent inner walls of the exoskeleton close to the rear side wall of the one-way lift-pressure faucet.

[0011] As a preferred embodiment, the exoskeleton is provided with a plurality of equally spaced lightweight grooves, each of the lightweight grooves is movably mounted on the outer side of the positioning seat, and each of the positioning seats is provided with a symmetrically arranged inclined surface at the outer end facing away from the one-way lift-pressure faucet.

[0012] As a preferred embodiment, both ends of the exoskeleton facing the water collecting cylinder extend and wrap around the outside of the sleeve, and a gap is provided between the two ends. A guide groove is provided in the gap and is opened in the middle of a side wall of the sleeve facing the water collecting cylinder. The cross section of the guide groove is a convex structure. A guide seat with a convex cross section is slidably connected in the guide groove. A C-shaped clamping plate is integrally fixed to the outer end of the guide seat facing the water collecting cylinder. As a preferred embodiment, the inner wall of the C-shaped clamp is provided with two symmetrically arranged second weakening grooves, and both ends of the C-shaped clamp are integrally formed with arc-shaped bending parts, and the C-shaped clamp is used to clamp and fix the metal braided reinforced hose.

[0013] As a preferred embodiment, two symmetrically arranged arc-shaped buckle blocks are fixed on the outer arc wall of the C-shaped clamping plate, and a plurality of equidistantly arranged fastening grooves are provided on the outer walls of the two end extensions of the exoskeleton toward the water collecting tube, and the ends of the arc-shaped buckle blocks away from the C-shaped clamping plate are inserted tightly into the corresponding fastening grooves.

[0014] Compared with the prior art, the anti-drip water-saving valve provided by the present invention has at least the following beneficial effects: In the present invention, when the anti-drip water-saving valve is used, if the lifting handle of the one-way lifting and pressure faucet is not closed firmly, water leakage will occur above the top opening of the water collection cylinder and at the water outlet arranged at the bottom end of the one-way lifting and pressure faucet, and the leaked water will be collected in the water collection cylinder. When the leaked water is collected in the water collection cylinder, the gravity generated will drive the two lifting rods to move downward, and the rubber roller will press the lifting handle downward to reset it to a compressed state, so as to ensure that the lifting handle will not cause water leakage and waste due to not being closed tightly. Secondly, when the rotating shaft, sealing ring and other parts of the lifting and pressing handle will increase friction resistance due to scale deposition and material aging, if the lifting and pressing handle is not closed firmly due to manual pressing, the metal braided reinforced hose can be pulled out from the C-type clamping plate, and at this time, without the metal braided reinforced hose squeezing the C-type clamping plate, the outer ends of the two arc-shaped buckle blocks are pulled out from the buckling grooves, and the C-type clamping plate connected to the guide seat can be manually adjusted to move the height on the sleeve, and then the metal braided reinforced hose is quickly inserted into the C-type clamping plate through the two arc-shaped bending parts, and the extrusion of the two second weakened grooves is combined. Due to the compression deformation effect, the outer ends of the two arc-shaped buckle blocks fixed on the outer arc walls of the two C-shaped clamping plates are reinserted into the corresponding fastening grooves. On the one hand, the top height of the metal braided reinforced hose can be adjusted and fixed. On the other hand, while adjusting and fixing, the exoskeleton and the sleeve can be quickly fixed on the one-way lift-pressure faucet with the help of the fixation of the metal braided reinforced hose to achieve the effect of rapid installation and fixation. In summary, this allows the water collection cylinder to collect different amounts of water so as to actively compensate for the lift-pressure handles with different increased friction resistance and press and reset.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The following examples are intended to illustrate the present invention but are not intended to limit the scope of protection of the present invention.

[0020] Example

[0021] In the prior art, one-way pressure-type faucets 11, such as push-type and lift-type faucets, are widely used in public places and homes due to their advantages such as convenient operation and water conservation. These faucets usually use spring return or magnetic attraction structures to achieve automatic closure of the valve core, but the following problems still exist in actual use: Relying on manual tightening, it is easy to cause leakage due to improper operation: Existing valves often rely on the user's pressure or lift to achieve a seal. If they are not completely closed, a small gap will form between the valve core and the sealing surface, causing continuous water leakage. Long-term leakage not only wastes water resources, but may also cause scale deposition, further exacerbating seal failure. Lack of gravity self-compensating closing mechanism for water leakage: The existing technology does not use the gravity of the leaking water as a power source to assist the valve in closing. When the valve is not closed tightly and water leaks, the leaking water droplets cannot be collected and converted into mechanical energy, and automatic tightening and sealing cannot be achieved. After long-term use, the friction resistance increases and the closing force is insufficient: The valve handle's shaft, seals, and other components can experience increased friction due to scale deposits, material aging (e.g., rubber hardening), and metal oxidation. At this point, the original spring or magnetic structure's reset force may not be sufficient to fully close the valve, requiring the user to apply greater pressure, otherwise leakage will continue. To do this, see Figure 1-8 The present invention provides a drip-proof water-saving valve, comprising: a one-way lift-pressure faucet 11 fixedly connected to the top of a wash basin 1, a lift-pressure handle 12 being provided on the top of the one-way lift-pressure faucet 11, a water-collecting gravity press-reset component 2 being connected between the lift-pressure handle 12 and the one-way lift-pressure faucet 11, the water-collecting gravity press-reset component 2 being used to collect the gravity of water leakage generated when the lift-pressure handle 12 on the one-way lift-pressure faucet 11 is not tightly closed, and drive the lift-pressure handle 12 to actively close; a height-adjustable positioning component 3 is also connected between the water-collecting gravity press-reset component 2 and the one-way lift-pressure faucet 11, the height-adjustable positioning component 3 being used to adjust and adapt to the change in friction resistance of the lift-pressure handle 12 caused by long-term use, and utilizing the difference in gravitational potential energy of the collected dripping water to achieve precise compensation for the closing force of the lift-pressure handle 12.

[0022] The one-way lift-and-press faucet 11 is a valve faucet in the prior art, and its lift-and-press handle 12 can only be lifted up or pressed down.

[0023] Further, if Figure 1-8As shown, in order to be able to use the gravity of the water when the mobile phone leaks to achieve the active closure of the lifting and pressing handle 12, a water collecting gravity pressing reset component 2 is provided, which includes a U-shaped bracket 21 sleeved on the outside of the one-way lifting and pressing faucet 11, and the two side walls of the U-shaped bracket 21 are integrally formed with a guide rail 211 with a convex structure in vertical section, and a sliding sleeve 22 is slidably sleeved on the two guide rails 211, and a lifting rod 23 with an L-shaped structure in vertical section is movably inserted on the two sliding sleeves 22, and a water collecting cylinder 25 with a same conical structure is fixed between the bottom ends of the two lifting rods 23, and the bottom end of the water collecting cylinder 25 is connected to a telescopic hose 27 through an S-shaped metal braided reinforced hose 26, and a rubber roller 24 is rotatably connected between the top ends of the two lifting rods 23, and the rubber roller 24 is movable Fitted to the top of the lifting and pressing handle 12, the two sliding sleeves 22 are rotatably connected to the side walls opposite to each other with push-pull rods 28, and the other ends of the two push-pull rods 28 are rotatably connected to the outside of the sleeve 29 with the same vertical cross-section and a mouth-shaped structure. The sleeve 29 is movably sleeved on the outside of the lifting and pressing handle 12, and the inner wall of the sleeve 29 is slidably connected to a pressure plate 210 with an I-shaped cross-section. Both ends of the pressure plate 210 are integrally formed with sliding parts with a convex cross-section. The two sliding parts are symmetrically arranged, and the sliding parts are slidably connected to the sliding grooves opened on the inner wall of the sleeve 29. The bottom end of the pressure plate 210 is provided with a rubber pad, and a hand screw 212 is threadedly connected at the center of the top of the sleeve 29. The bottom end of the hand screw 212 is rotatably connected to the center of the top of the pressure plate 210. Among them, the metal braided reinforced hose 26 mainly achieves the characteristics of internal flexibility and external high hardness through a composite laminate structure. It is an existing technology and can be bent at will. The setting of the telescopic hose 27 can facilitate the adjustment of the length of the telescopic hose 27 according to the different depths of the wash basins 1. The higher the top bend of the metal braided reinforced hose 26, the more leaked water is collected in the water collecting cylinder 25. When the liquid level of the leaked water collected in the water collecting cylinder 25 is higher than the top bend of the metal braided reinforced hose 26, the excess leaked water will flow along the metal braided reinforced hose 26 and the telescopic hose 27. On the contrary, when the liquid level of the leaked water collected in the water collecting cylinder 25 is lower than the top bend of the metal braided reinforced hose 26, a certain amount of leaked water can be collected in the water collecting cylinder 25 to achieve the active closure of the gravity compensation lifting and pressing handle 12. Since the rubber roller 24 is connected to the two sliding sleeves 22 by two lifting plates and can be lifted and slid, the height of the rubber roller 24 can be adjusted by the height of the lifting and pressing handle 12. Therefore, in conjunction with the setting of the push-pull rod 28, the sleeve 29 can be sleeved on the outside of the lifting and pressing handle 12 at different heights from the one-way lifting and pressing faucet 11. The pressure plate 210 can also be pressed and fixed to the outside of the lifting and pressing handle 12 of different thicknesses by rotating the hand-tightening screw 212, so as to achieve the purpose of convenient installation and a wide range of applications.

[0024] Furthermore, if Figure 1-8As shown, in order to be able to adjust the amount of water leakage collected by the hand according to the different friction resistance changes caused by aging of the lifting and pressing handle 12, so as to achieve the purpose of actively compensating for the pressing and closing of the lifting and pressing handle 12, a height-adjustable positioning component 3 is provided, including a sleeve 31 with a U-shaped cross-section and an L-shaped vertical section fixed to the bottom end of the U-shaped bracket 21, and a plurality of equidistantly arranged alignment seats 311 are fixed to the two side walls of the sleeve 31, and the outer sides of the plurality of alignment seats 311 provided on both sides and the outer side of the sleeve 31 are movably sleeved with an outer skeleton 32 with the same U-shaped cross-section, and the two bent inner walls of the outer skeleton 32 near the rear side wall of the one-way lifting and pressing faucet 11 are provided with first weakening grooves 321, and the outer skeleton 32 is provided with a plurality of equidistantly arranged lightweight grooves 322, each lightweight groove 322 is movably sleeved on the outer side of the alignment seat 311, and each alignment seat 311 is symmetrically provided at the outer end facing away from the one-way lifting and pressing faucet 11. The inclined surface 312, both ends of the outer frame 32 facing the water collecting cylinder 25 extend and wrap around the outside of the sleeve 31, and there is a gap between the two ends. A guide groove is provided in the gap, which is opened in the middle of the side wall of the sleeve 31 facing the water collecting cylinder 25. The cross section of the guide groove is a convex structure. A guide seat 33 with a convex cross section is slidably connected in the guide groove. A C-shaped card plate 34 is fixed to the outer end of the guide seat 33 facing the water collecting cylinder 25. The inner wall of the C-shaped card plate 34 is provided with a symmetrical arrangement. Two second weakening grooves 35 are formed at both ends of the C-shaped clamping plate 34 with an integral arc-shaped bent portion 36. The C-shaped clamping plate 34 is used to clamp and fix the metal braided reinforced hose 26. Two symmetrically arranged arc-shaped buckle blocks 37 are fixed to the outer arc wall of the C-shaped clamping plate 34. A plurality of equidistantly arranged fastening grooves 38 are provided on the outer wall of the extension portions at both ends of the exoskeleton 32 toward the water collecting cylinder 25. The ends of the arc-shaped buckle blocks 37 away from the C-shaped clamping plate 34 are tightly inserted into the corresponding fastening grooves 38.

[0025] Among them, all components except the metal braided reinforced hose 26 and the telescopic hose 27 can be made of ABS plastic material and can be manufactured in one piece, with low manufacturing cost; The first weakened groove 321 is provided to enable the exoskeleton 32 to be split apart and to be sleeved on the outside of the sleeve 31. Furthermore, the exoskeleton 32 can be sleeved on the outside of the plurality of alignment seats 311 by means of the plurality of lightweight grooves 322 to ensure that the exoskeleton 32 and the sleeve 31 are fitted together. Furthermore, the exoskeleton 32 and the sleeve 31 are quickly fixed to the outside of the one-way lift-type faucet 11 by means of the force exerted by the metal braided reinforced hose 26 inserted into the C-shaped clamping plate 34. The arc-shaped bend 36 is for inserting the metal braided reinforced hose 26, which allows the C-shaped clamping plate 34 to quickly expand outward through the two second weakened grooves 35, so that one end of the arc-shaped buckle block 37 can be inserted into the fastening groove 38 at the corresponding height position.

[0026] In summary, when the anti-drip water-saving valve is used, if the lifting handle 12 of the one-way lifting and pressure faucet 11 is not closed firmly, water leakage will occur above the top opening of the water collecting cylinder 25 and at the water outlet arranged at the bottom end of the one-way lifting and pressure faucet 11. The leaked water is collected in the water collecting cylinder 25. When the leaked water is collected in the water collecting cylinder 25, the gravity generated will drive the two lifting rods 23 to move downward, and the rubber roller 24 will press the lifting handle 12 downward to reset it to a compressed state, so as to ensure that the lifting handle 12 will not leak and waste water due to not being closed tightly. Secondly, when the rotating shaft, sealing ring and other components of the lifting and pressing handle 12 will increase friction resistance due to scale deposition and material aging, if the lifting and pressing handle 12 is not closed firmly due to manual pressing, the metal braided reinforced hose 26 can be pulled out from the C-shaped clamping plate 34, and at this time, without the metal braided reinforced hose 26 squeezing the C-shaped clamping plate 34, the outer ends of the two arc-shaped buckle blocks 37 are both pulled out from the fastening grooves 38, and the C-shaped clamping plate 34 connected to the guide seat 33 can be manually adjusted to move the height on the sleeve 31, and then the metal braided reinforced hose 26 is quickly inserted into the C-shaped clamping plate 34 through the two arc-shaped bending parts 36, and the two second The extrusion deformation effect of the weakened groove 35 allows the outer ends of the two arc-shaped buckle blocks 37 fixed on the outer arc walls of the two C-shaped clamps 34 to be reinserted into the corresponding fastening grooves 38. On the one hand, the top height of the metal braided reinforced hose 26 can be adjusted and fixed. On the other hand, while adjusting and fixing, the outer skeleton 32 and the sleeve 31 can be quickly fixed on the one-way lift-pressure faucet 11 with the help of the fixation of the metal braided reinforced hose 26 to achieve the effect of rapid installation and fixation. In summary, this allows the water collection cylinder 25 to collect different amounts of water so as to actively compensate for the lift-pressure handle 12 with different increased friction resistance and press and reset.
