Description

Technical Field

[0001] This invention relates to the field of water-saving technology for time-delay self-closing valves, and in particular to an intelligent valve faucet with automatic flow interruption function and its usage method. Background Technology

[0002] The core function of a time-delay self-closing valve is to achieve automatic closing after a delay through mechanical structures (such as springs and damping devices). Typical applications include bathroom flushing equipment and water-saving faucets, which have a water-saving function. Its structure includes components such as valve body, spring, sealing ring, and damper. Its technical features include ① support for manual or automatic control of opening and closing, ② precise control of closing time, and ③ adjustable delay function.

[0003] Existing time-delay self-closing valves have several technical defects. First, current time-delay self-closing valves have low sensitivity and excessively long delays, resulting in poor water-saving effects. The transmission structure is also prone to jamming, leading to a short service life. Second, after a period of use, scale and other impurities accumulate on the outer surface of the valve core, causing water pollution. Failure to clean it in time will also accelerate the corrosion of the valve core. Third, in actual use, problems such as wear on the bottom of the valve cavity and valve core, as well as insufficient downward pressure of the valve core due to water pressure, can lead to poor sealing and leakage. This is particularly noticeable when installing downward-sloping faucets.

[0004] In summary, considering that existing facilities cannot meet the needs of work, we propose an intelligent valve faucet with automatic flow interruption function and its usage method. Summary of the Invention

[0013] As a preferred embodiment of the intelligent valve faucet with automatic flow interruption function described in this invention, wherein: a guide pipe is fixedly installed inside the water pressure flow channel, and a sealing nozzle is installed at the upwardly extending end of the guide pipe. The sealing nozzle is riveted to the upper end face of the annular support platform using an ear piece. The sealing nozzle is slidably and sealingly fitted to the upper end face of the water supply part. Several sets of water injection holes interacting with the sealing nozzle are evenly opened on the upper end face of the water supply part. The number of water injection holes is preferably 3-4 sets. A one-way pressure valve is installed in each set of water injection holes. A diversion cavity communicating with the water injection holes is opened inside the water supply part. An annular diversion pipe is sealed and connected to the lower end of the diversion cavity. Several sets of distributed cleaning holes acting on the corresponding rollers are evenly distributed on the lower end face of the annular diversion pipe. The number of distributed cleaning holes is preferably 6-12 sets. A drain cover is fixedly installed at the lower position of the outer side of the dirt removal seat. The drain cover is connected to the interior of the dirt removal seat.

[0014] As a preferred embodiment of the intelligent valve tap with automatic flow interruption function described in this invention, the bottom of the sealed valve cavity is provided with a squeezing groove, and a sealing oil bladder that interacts with the gravity valve core is installed in the squeezing groove. Part of the sealing oil bladder extends out of the squeezing groove. Positioning oil pipes are fixedly installed at the lower positions of both ends of the sealing oil bladder. A positioning connector is connected to the end of each group of positioning oil pipes away from the sealing oil bladder. A hydraulic oil pipe is installed at the upper end of the positioning connector. A hydraulic sleeve is connected to the upper end of the hydraulic oil pipe. There are two groups of hydraulic sleeves. The hydraulic sleeves are inclined downwards. A hydraulic rod is movably installed outwards inside the hydraulic sleeve. An arc-shaped squeezing head that acts on the upper end face of the gravity valve core is installed at the lower end of the hydraulic rod. A return spring is sleeved on the hydraulic rod.

[0015] A method for using an intelligent valve faucet with automatic flow interruption function includes the following steps: S1: By turning the anti-slip head on the rotary switch, a series of transmissions cause the drum on the rotating rod to rotate, winding the steel wire rope and pulling the gravity valve core to move straight upward from the bottom of the sealed valve chamber.

[0016] S2: When water enters the outlet channel and causes the water level to rise, the two sets of foam floats remain on the water surface due to buoyancy. The repulsive force causes the swing arm to swing, and the two sets of hooks interact with the ratchet respectively, causing the rotating rod to rotate and gradually loosen the wire rope on the drum. The gravity valve core moves into the sealing valve cavity by its own weight.

[0017] S3: The servo motor is started immediately. After a series of transmissions, the cleaning seat makes intermittent circular motions around the ring support platform. During the motion, several sets of rollers on the cleaning seat use the cotton cloth layer to contact the outer surface of the gravity valve core to generate a wiping action and wipe away the dirt on the outer surface of the gravity valve core.

[0018] S4: When the gravity valve core contacts the sealing oil bladder, it squeezes it, causing some of the hydraulic oil in the sealing oil bladder to flow into the hydraulic oil pipe through the positioning oil pipes on both sides, supplying oil to the hydraulic sleeve. The hydraulic force causes the high-sensitivity hydraulic rod to tilt downward and extend, which acts on the upper end face of the gravity valve core.

[0019] This invention provides an intelligent valve faucet with automatic flow interruption function and its usage method, which has the following significant improvements and advantages compared with the prior art: Two sets of foam floats remain on the water surface due to buoyancy, causing the repulsive magnets on the two sets of balance blocks to move upwards to a certain height. The two sets of repulsive magnets repel the two pole magnets, causing the pendulum to swing. This causes the low-resistance drum to rotate outside the fixed shaft. When the pendulum swings to the highest point on one side, the hook on the other side is at its lowest point. The inclined surface of the triangular stop hooks the ratchet. When the pendulum swings back to the other side, the ratchet rotates in the opposite direction under the restoring force of the torsion spring, causing the rotating rod to rotate. This releases the wire rope on the drum, allowing the gravity valve core to move into the sealing valve cavity by its own weight. When the pendulum swings to the highest point on the other side, the hook on one side is at its lowest point. The straight surface of the triangular stop blocks the ratchet, stopping the downward movement of the gravity valve core and achieving the purpose of delayed self-closing. This method has high sensitivity, significant delay and water-saving effects, and uses a wire rope instead of a mechanical arm, reducing the probability of jamming and effectively extending the service life.

[0020] The servo motor is started, and through a series of transmissions, the cleaning seat makes intermittent circular motion around the annular support platform. During the movement, several sets of rollers on the cleaning seat make contact with the outer surface of the gravity valve core using the cotton cloth layer, generating a wiping action to remove the stains on the outer surface of the gravity valve core, achieving automatic cleaning and saving time and effort. The force of each set of rollers contacting the gravity valve core causes the upper suspension bearing at the top of the roller to rotate around the suspension axis, and the lower sliding bearing to move along the curved groove arc, thereby enabling the roller to automatically adjust its angle to adapt to the movement of the gravity valve core, increasing the effective wiping area, improving the wiping effect, and providing a buffer protection effect for the cleaning device.

[0021] The sealed nozzle is positioned precisely at one of the water injection holes. After the two are connected, the guide pipe cleverly introduces water from the water pressure channel, which acts on the one-way pressure valve of the water injection hole, opening the one-way pressure valve and injecting a certain amount of water into the diversion chamber. Due to the instantaneous water pressure, the water in the diversion chamber is sprayed downwards from several sets of distributed cleaning holes in the bottom annular diversion pipe, each rinsing the cotton cloth layer of the roller below, automatically washing away the dirt on the cotton cloth layer, avoiding cross-contamination of the valve core by the dirty cotton cloth layer, and cooperating with the rotating roller to make the cotton cloth layer clean in a circular motion, with high uniformity and effectively improving the cleaning effect.

[0022] When the gravity valve core contacts the sealing oil bladder during its self-closing process, it is squeezed and deformed. This causes some of the hydraulic oil in the sealing oil bladder to flow into the hydraulic oil pipe through the positioning oil pipes on both sides, supplying oil to the hydraulic sleeve. The hydraulic force causes the highly sensitive hydraulic rod to tilt downward and extend, using the arc-shaped extrusion head to squeeze the gravity valve core. This compresses the sealing oil bladder, increasing the sealing force between the two and improving the sealing effect. On the other hand, it increases the auxiliary pressure, allowing the gravity valve core to fully fit against the bottom of the sealing valve cavity, thus solving the problem of unstable downward pressure of the gravity valve core.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0026] like Figures 1-15 As shown, this embodiment provides an intelligent valve faucet with automatic flow interruption function, including a time-delay self-closing valve body 1. The right end of the time-delay self-closing valve body 1 is connected to a water outlet faucet 2, and the left end of the time-delay self-closing valve body 1 is connected to a water inlet short pipe 3. A flange 4 is provided at the end of the water inlet short pipe 3, and a valve cover 5 is provided at the upper end of the time-delay self-closing valve body 1. A rotary switch 6 is connected to the end of the valve cover 5 by means of a damping bearing 8. The damping bearing 8 provides damping force, and an anti-slip screw head 7 is provided at the upper end of the rotary switch 6, which has an anti-slip function.

[0027] Furthermore, a valve stem 10 is fixedly mounted vertically downwards on the inner surface of the rotary switch 6, and a first bevel gear 11 is sleeved on the lower end of the valve stem 10. A rotating rod 12 is horizontally rotatable inside the time-delay self-closing valve body 1. Figures 2-4 As shown.

[0028] The left end of the rotating rod 12 is fitted with a second bevel gear 13 that meshes with the first bevel gear 11, such as... Figure 2 and Figure 3 As shown.

[0029] In this embodiment, the middle part of the rotating rod 12 is connected to the positioning seat 14 via a positioning bearing 15, serving a positioning function. The positioning seat 14 is riveted to the inside of the time-delay self-closing valve body 1. A torsion spring 16 (or a clockwork spring) is sleeved on the outside of the rotating rod 12 between the first bevel gear 11 and the positioning seat 14. Figure 5 and Figure 6 As shown.

[0030] In this embodiment, a drum 20 is sleeved on the middle of the rotating rod 12 and located on the right side of the positioning seat 14. A steel wire rope 21 is wound on the drum 20 (the drum 20 has only a single winding groove). The lower end of the steel wire rope 21 is connected to a gravity valve core 22. The gravity valve core 22 is made of a high-density, corrosion-resistant metal material, which can overcome water pressure and smoothly raise and lower the load. Figure 5 and Figure 6 As shown.

[0031] The delayed self-closing valve body 1 has a sealed valve chamber 23 located at its lower interior, into which the gravity valve core 22 extends. A water pressure channel 24 is connected to the left side of the sealed valve chamber 23, providing sufficient water pressure. The water pressure channel 24 is connected to the inlet short pipe 3. An outlet channel 25 is connected to the right side of the sealed valve chamber 23, and the outlet channel 25 is connected to the water tap 2. Figure 8 As shown.

[0032] In this embodiment, a ratchet 17 is sleeved on the right end of the rotating rod 12, and several sets of ratchet teeth 18 are evenly distributed on the ratchet 17, such as... Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown.

[0033] Furthermore, a magnetic pole oscillation structure is provided on the outer side of the ratchet 17. The magnetic pole oscillation structure includes a connecting platform 30 fixed to the inside of the delayed self-closing valve body 1. A fixed shaft 31 extends horizontally outward from the middle of the connecting platform 30. A low-resistance rotating cylinder 32 is rotatably mounted outside the fixed shaft 31. The low-resistance rotating cylinder 32 has low resistance when rotating, such as... Figure 7 As shown.

[0034] Two sets of hook rods 33 are symmetrically mounted on the low-resistance rotating drum 32. The ends of the hook rods 33 are equipped with triangular stops 34 that interact with the ratchet 18. The triangular stops 34 include a straight stop surface and an inclined stop surface. The triangular stops 34 do not affect the counterclockwise rotation of the ratchet 17. A swing rod 35 is vertically connected to the bottom of the low-resistance rotating drum 32. A swing body 36 is mounted at the lower end of the swing rod 35. Two-pole magnets 37 are fixed to the swing body 36, with their poles symmetrically distributed. Initially, the swing body 36 is stationary. The stationary state of the swing body 36 is broken by the asynchronous upward movement of the two sets of mutually repulsive magnets 47, or by making the magnetization intensity of the two sets of mutually repulsive magnets 47 different. Figure 7 As shown.

[0035] Furthermore, two sets of limiting frames 40 are symmetrically distributed on the sidewall of the water outlet channel 25, and foam floats 41 are movably installed outside the limiting frames 40, such as... Figure 8 and Figure 9 As shown.

[0036] Specifically, a guide block 44 is connected to the side of the foam float 41 via a connecting part 43. A guide groove 42 is vertically formed inside the limiting frame 40 to allow the guide block 44 to move. The guide groove 42 is slightly larger than the cross-sectional area of ​​the guide block 44. A support rod 45 is vertically connected to the middle of the upper end face of the foam float 41. A balance block 46 is installed at the upper end of the support rod 45. The balance block 46 is used to improve the balance and stability of the foam float 41 on the water surface. A repulsive magnet 47, which interacts with the bipolar magnet 37, is installed on the inclined surface of the balance block 46. Figure 9 As shown.

[0037] Furthermore, an annular support platform 50 is fixedly installed inside the delayed self-closing valve body 1 and above the sealing valve cavity 23. A dirt-removing seat 51 is sleeved on the inner side of the annular support platform 50 via a rotary bearing 58. The dirt-removing seat 51 moves around the annular support platform 50. The upper part of the dirt-removing seat 51 includes a water supply section 52, such as... Figure 10 and Figure 11 As shown.

[0038] Among them, a large gear 53 is sleeved on the outer side of the cleaning seat 51, and the large gear 53 extends into the interior of the annular support platform 50. A small gear 54 is meshed on the outer side of the large gear 53, and the small gear 54 is sleeved on the output shaft of the servo motor 55. The servo motor 55 vertically passes through the drive seat 56, and the drive seat 56 is connected to the annular support platform 50. Figure 10 and Figure 12 As shown.

[0039] Furthermore, several sets of wheel grooves 57 are evenly distributed around the inner side of the dirt-removing seat 51, and a dirt remover 60 is provided in each set of wheel grooves 57 extending into the interior of the dirt-removing seat 51. Figure 11 As shown.

[0040] Specifically, the dirt separator 60 includes a roller 61, a cotton cloth layer 62, a roller shaft 63, an upper suspension bearing 64, a suspension shaft 65, a lower sliding bearing 66, a curved groove 67, and a curved spring 68, such as... Figure 14 As shown.

[0041] In this embodiment, the roller 61 is located inside the groove 57 and partially extends outward from the groove. The outer side of the roller 61 is wrapped with a cotton cloth layer 62, which has a certain thickness. The cotton cloth layer 62 is in contact with the outer surface of the gravity valve core 22. Roller shafts 63 are welded to both the upper and lower ends of the roller 61. An upper suspension bearing 64 is installed at the upper end of the upper roller shaft 63. The upper suspension bearing 64 is connected to the inner wall of the cleaning seat 51 by means of a suspension shaft 65. A lower sliding bearing 66 is installed at the lower end of the lower roller shaft 63. The lower sliding bearing 66 is movably disposed in the curved groove 67, which is opened inside the cleaning seat 51. The lower sliding bearing 66 and the groove wall of the curved groove 67 are connected by a curved spring 68. When the curved spring 68 is compressed, it generates a force that pushes the lower sliding bearing 66 back to its original position.

[0042] Furthermore, a guide pipe 70 is fixedly installed inside the water pressure flow channel 24. A sealing nozzle 71 is installed at the upward-extending end of the guide pipe 70. The sealing nozzle 71 is riveted to the upper end face of the annular support platform 50 using a lug 72. The sealing nozzle 71 slides and seals against the upper end face of the water supply section 52, thus achieving a sealing effect. Figure 2 , Figure 3 and Figure 10 As shown.

[0043] The water supply unit 52 has several sets of water injection holes 73 evenly distributed on its upper surface, which interact with the sealing nozzles 71. Each set of water injection holes 73 is equipped with a one-way pressure valve 74. The water supply unit 52 has a diversion chamber 75 inside that communicates with the water injection holes 73. Figure 10 , Figure 11 and Figure 15 As shown.

[0044] The lower end of the diversion chamber 75 is sealed with an annular diversion pipe 76. Several sets of distributed cleaning holes 77 acting on the corresponding rollers 61 are evenly distributed on the lower end face of the annular diversion pipe 76. A drain hood 78 is fixedly installed on the lower part of the outer side of the cleaning seat 51. The drain hood 78 and the interior of the cleaning seat 51 are connected. The inner wall of the delayed self-closing valve body 1 is provided with a drain structure for receiving sewage from the drain hood 78 and conveying it outwards. Figure 11 , Figure 13 and Figure 15 As shown.

[0045] It should be noted that the dimensions and proportions of the parts in the accompanying drawings are not limited and should be designed according to requirements.

[0046] In this embodiment, when water is used, the anti-slip screw head 7 on the rotary switch 6 is turned, and the rotary switch 6 rotates around the damping bearing 8, thereby causing the valve stem 10 to drive the first bevel gear 11 to rotate. Through meshing and reversing transmission, the second bevel gear 13 on the rotating rod 12 rotates (the torsion spring 16 is twisted), thereby causing the drum 20 on the rotating rod 12 to rotate as well, winding the steel wire rope 21, and pulling the gravity valve core 22 to move straight upward from the bottom of the sealed valve cavity 23. The sealed valve cavity 23 is opened, and the water in the water pressure channel 24 passes through the sealed valve cavity 23 and the water outlet channel 25 in sequence, and water comes out from the water tap 2.

[0047] When water enters the outlet channel 25, causing the water level to rise, the two sets of foam floats 41 remain on the water surface due to buoyancy (during the upward movement of the foam floats 41, the guide block 44 moves upward along the guide groove 42 to the upper limit). This causes the repulsive magnets 47 on the two sets of balance blocks 46 to move upward to a certain height. The two sets of repulsive magnets 47 repel the two pole magnets 37 respectively, causing the swing body 36 to be subjected to an unbalanced force, thereby causing the swing rod 35 to swing (when the swing body 36 swings to the higher point, it overcomes its own weight and repulsive force, and at the higher point, it is subjected to the dual force of its own weight and repulsive force, generating the power source for the swing back, and so on). This causes the low-resistance rotating drum 32 to rotate outside the fixed shaft 31. The low-resistance rotating drum 32 drives the two sets of hook rods 33 to move symmetrically. When the swing body 36 swings to the highest point on one side, the hook rod 33 on the other side is at the lowest point, which is beneficial to... The inclined surface of the triangular stop 34 hooks the ratchet 18. When the swing body 36 swings back to the other side, the inclined surface and the ratchet 18 separate. The ratchet 17 rotates in the opposite direction under the restoring force of the torsion spring 16, thereby causing the rotating rod 12 to rotate. The wire rope 21 on the drum 20 is released, allowing the gravity valve core 22 to move into the sealing valve cavity 23 by its own weight. When the swing body 36 swings to the highest point on the other side, the hook rod 33 on one side is at the lowest point. The straight surface of the triangular stop 34 blocks the ratchet 18, causing the downward movement of the gravity valve core 22 to stop. This is repeated many times until the gravity valve core 22 is completely placed in the sealing valve cavity 23, realizing the delayed self-closing of the faucet 2. As the water level in the outlet channel 25 decreases after self-closing, the position of the foam float 41 drops, and the repulsive force of the two sets of mutually repulsive magnets 47 on the swing body 36 disappears due to the increased distance.

[0048] When it is necessary to clean the outer surface of the gravity valve core 22, the gravity valve core 22 automatically moves downward after reaching its highest point, immediately activating the servo motor 55, which drives the pinion gear 54 to rotate, and through meshing and deceleration, causes the large gear 53 to rotate. The cleaning seat 51 performs intermittent circular motion around the annular support platform 50. During the movement, several sets of rollers 61 on the cleaning seat 51 contact the outer surface of the gravity valve core 22 using the cotton cloth layer 62, generating a wiping action to remove the stains from the outer surface of the gravity valve core 22. The gravity valve core 22 moves vertically, while the cleaning seat 51 moves in a circular motion. Therefore, when each set of rollers 61 comes into contact with the gravity valve core 22, the rollers 61 are subjected to reaction forces in two directions. On the one hand, the upper suspension bearing 64 at the upper end of the roller 61 rotates around the suspension shaft 65, causing the lower sliding bearing 66 to move along the arc of the curved groove 67 and squeeze the curved spring 68, thereby causing the rollers 61 to automatically adjust their angle to match the movement of the gravity valve core 22 and improve the wiping effect. On the other hand, the rollers 61 continue to rotate around the bearing.

[0049] When the gravity valve core 22 stops, the dirt removal seat 51 is in the intermittent period of its circular motion. The sealing nozzle 71 is exactly at the position of one of the sets of water injection holes 73. After the two are connected, the water introduced into the water pressure channel 24 by the guide pipe 70 acts on the one-way pressure valve 74 of the water injection hole 73, opening the one-way pressure valve 74 and injecting a certain amount of water into the diversion chamber 75. Due to the instantaneous water pressure (the upper part of the diversion chamber 75 is in a closed state), the water in the diversion chamber 75 is sprayed downward from several sets of collection and distribution cleaning holes 77 of the bottom annular diversion pipe 76, which respectively rinse the cotton cloth layer 62 of the lower roller 61 (since the roller 61 is rotating, the cotton cloth layer 62 can be fully rinsed), washing away the stains on the cotton cloth layer 62 and forming sewage. The sewage is dispersed and discharged outward from the drain cover 78. Example 2 Based on Embodiment 1, in actual use, problems such as wear at the bottom of the sealing valve chamber 23 and the gravity valve core 22, and insufficient downward pressure of the gravity valve core 22 due to water pressure, can lead to poor sealing and leakage. This is particularly noticeable when installing a downward-sloping faucet 2. To solve the above technical problems, we have the following design, such as... Figure 16 and Figure 17 As shown.

[0050] Specifically, a squeezing groove 80 is provided at the center of the bottom of the sealing valve cavity 23. A sealing oil bladder 81 that interacts with the gravity valve core 22 is installed in the squeezing groove 80. The sealing oil bladder 81 has the characteristic of deformation and reset. Part of the sealing oil bladder 81 extends out of the squeezing groove 80.

[0051] Furthermore, positioning oil pipes 82 are fixedly installed at the lower positions of both ends of the sealing oil bladder 81, and a positioning connector 83 is connected to the end of each positioning oil pipe 82 away from the sealing oil bladder 81.

[0052] The upper end of the positioning joint 83 is equipped with a hydraulic oil pipe 84, and the upper end of the hydraulic oil pipe 84 is connected to a hydraulic sleeve 85. The hydraulic sleeve 85 is inclined downward, and a hydraulic rod 86 is movably installed inside the hydraulic sleeve 85. An arc-shaped extrusion head 87 that acts on the upper surface of the gravity valve core 22 is installed at the lower end of the hydraulic rod 86. A return spring is sleeved on the hydraulic rod 86. When the return spring is stretched, it drives the hydraulic rod 86 to automatically return to its original position.

[0053] In this embodiment, when the gravity valve core 22 contacts the sealing oil bladder 81 extending out of the extrusion groove 80 during the self-closing process, it is squeezed and deformed, causing some of the hydraulic oil in the sealing oil bladder 81 to flow into the hydraulic oil pipe 84 through the positioning oil pipes 82 on both sides, supplying oil to the hydraulic sleeve 85. Thus, the hydraulic force causes the highly sensitive hydraulic rod 86 to tilt downward and extend, which acts on the upper end face of the gravity valve core 22. The arc extrusion head 87 squeezes the gravity valve core 22, providing auxiliary force to further compress the sealing oil bladder 81 and increase the sealing force between the two. On the other hand, it makes the gravity valve core 22 fully fit against the bottom of the sealing valve cavity 23.
