Description

Technical Field

[0001] This invention relates to the field of water purifier pipe connector technology, specifically to a leak-proof self-locking connector structure for water purifier pipes. Background Technology

[0002] During the use of a water purifier, the reliability of the pipeline connections is crucial to its normal operation. Traditional water purifier pipeline joints often face numerous problems. For example, some joints have poorly designed sealing structures, relying solely on a single sealing ring. With prolonged use or fluctuations in water pressure, the seal is prone to failure, leading to leaks. Furthermore, most of these traditional joints lack self-locking leak-proof functionality. Once a leak occurs, it can only be detected through manual inspection, often failing to stop the damage in time. This not only wastes water resources but may also damage surrounding furniture and appliances, causing unnecessary losses.

[0003] In addition, traditional connectors have a complex structure and messy connections between components. During assembly and maintenance, a lot of time is required for component alignment and installation, which greatly reduces the efficiency of assembly and maintenance. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a leak-proof self-locking connector structure for water purifier pipelines.

[0006] (II) Technical Solution

[0007] To solve the above problems, this application provides the following technical solution: a leak-proof self-locking connector structure for a water purifier pipeline, comprising a connector body, which is installed via a base plate. A connecting groove is provided inside the connector body, and two connecting connector assemblies are connected to both sides of the connecting groove. The two connecting connector assemblies are respectively connected to a water valve outlet and a water purifier inlet via pipelines. A sealing rod assembly is slidably connected to one side of the connecting groove. A sealing gasket is connected to one end of the sealing rod assembly located inside the connecting groove. The diameter of the sealing gasket is larger than that of the connecting connector assembly connected to the water purifier inlet, and it is used to seal the connecting connector assembly connected to the water purifier inlet under the push of the sealing rod assembly.

[0008] The other end of the sealing rod assembly extends through to one side of the connector body and is stretched and snapped onto the snap-fit ​​assembly. A second return spring is sleeved on the outside of the sealing rod assembly. The second return spring is located in the connecting groove. When the other end of the sealing rod assembly is snapped onto the snap-fit ​​assembly, the second return spring is in a compressed state, and the sealing gasket is disengaged from the connecting connector assembly that connects to the water purifier inlet, thus connecting the two connecting connector assemblies. When the other end of the sealing rod assembly is disengaged from the snap-fit ​​assembly, the second return spring is reset under the action of elasticity, so that the sealing gasket blocks the connecting connector assembly that connects to the water purifier inlet.

[0009] Preferably, the sealing rod assembly includes a connecting rod and a sealing rod, which are fixedly connected, and the connecting rod and the sealing rod are coaxially arranged with the connecting joint assembly that communicates with the water inlet of the water purifier.

[0010] Preferably, the sealing rod is fitted with several sets of second sealing rings, so that the sealing rod slides in a sealing manner inside the connecting groove. The sealing rod is slidably connected on one side of the connecting groove. One end of the sealing rod located inside the connecting groove is fixedly connected to the sealing gasket. A fourth sealing ring is fitted on the contact end of the connecting joint assembly that connects the sealing gasket to the water inlet of the water purifier.

[0011] Preferably, a locking head is fixedly installed below the other end of the connecting rod, the locking head is locked onto the locking assembly, and a pull rod is provided on the connecting rod, the pull rod being used to pull the connecting rod to slide within the connecting groove.

[0012] Preferably, a cover plate is fixedly installed on one side of the connector body by bolts to seal the connecting groove. Several sets of first sealing rings are provided at the sealing point of the cover plate and the connector body. The second return spring is sleeved on the connecting rod and located inside the connecting groove. One end of the second return spring contacts one side of the sealing rod and the other end contacts the inner side of the cover plate.

[0013] Preferably, the snap-fit ​​assembly includes a snap-fit ​​block with a snap-fit ​​groove on its upper side. The snap-fit ​​head matches the snap-fit ​​groove and is used to snap-fit ​​inside the snap-fit ​​groove. The snap-fit ​​block is rotatably connected to the mounting bracket via a rotating shaft. The mounting bracket is fixedly installed on the base plate. Rotating the snap-fit ​​block can disengage the snap-fit ​​head from inside the snap-fit ​​groove.

[0014] Preferably, a pressure plate is installed at the other end of the snap-fit ​​block. The pressure plate is located above the expansion assembly. The expansion assembly includes a frame groove and expansion cotton. The expansion cotton is disposed inside the frame groove. The expansion cotton absorbs water and expands to lift the pressure plate, causing the snap-fit ​​block to rotate around the pivot.

[0015] Preferably, a first reset spring is provided at the bottom of the snap-fit ​​block, and the first reset spring is fixedly installed on the base plate to reset the snap-fit ​​block.

[0016] Preferably, the base plate is provided with several sets of mounting ears around its perimeter, and the base plate is installed at the water purifier placement location by bolts. The bottom of the base plate is provided with an adhesive block for attaching the base plate to the water purifier placement location.

[0017] Preferably, the connecting connector assembly includes a connecting conduit that communicates with the interior of the connecting groove. The upper end of the connecting conduit is provided with a claw for inserting into the inlet and outlet water pipes. A third sealing ring is engaged on the outer side of the claw to secure the pipes. A retaining ring is provided inside the connecting conduit.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this application provides a leak-proof self-locking connector structure for water purifier pipelines, which has the following beneficial effects:

[0020] 1. The water purifier's leak-proof self-locking connector structure allows the expansion cotton to absorb moisture and expand when a leak occurs. This expansion cotton then pushes up the pressure plate, causing the locking block to rotate around the shaft and disengage the locking head from the slot. At this time, the second return spring resets under its elastic force, pushing the sealing rod assembly to move. This allows the sealing gasket to seal the connecting connector assembly at the water purifier's inlet, quickly cutting off the water path and achieving self-locking leak prevention. The rapid response effectively prevents the leakage from escalating.

[0021] 2. The water purifier's pipeline anti-leakage self-locking connector structure uses a rotating locking mechanism with a first reset spring for automatic reset, adapting to vibration environments such as the start and stop of the water purifier's water pump, ensuring stable locking / unlocking action.

[0022] 3. The water purifier features a leak-proof self-locking connector structure. The connector adopts a modular design, and the connection relationship between each component is clear. For example, the sealing rod assembly, snap-fit ​​assembly, and connecting connector assembly can all be disassembled and replaced individually. When a component is damaged, it is not necessary to replace the entire connector; only the corresponding component needs to be replaced, which greatly reduces maintenance costs and difficulty.

[0033] Please see Figures 1-3 This application provides a new technical solution: a leak-proof self-locking connector structure for a water purifier pipeline, including a connector body 100, which is installed via a base plate 600. The connector body 100 has a connecting groove 103 inside, and two connecting connector assemblies 700 are connected to both sides of the connecting groove 103. The two connecting connector assemblies 700 are respectively connected to a water valve outlet and a water purifier inlet via pipelines. A sealing rod assembly 500 is slidably connected to one side of the connecting groove 103. A sealing gasket 800 is connected to one end of the sealing rod assembly 500 inside the connecting groove 103. The diameter of the sealing gasket 800 is larger than that of the connecting connector assembly 700 connected to the water purifier inlet, and it is used to seal the connecting connector assembly 700 connected to the water purifier inlet under the pushing action of the sealing rod assembly 500.

[0034] The other end of the sealing rod assembly 500 extends through to one side of the connector body 100 and is stretched and snapped onto the snap-fit ​​assembly 400. A second return spring 900 is sleeved on the outside of the sealing rod assembly 500. The second return spring 900 is located in the connecting groove 103. When the other end of the sealing rod assembly 500 is snapped onto the snap-fit ​​assembly 400, the second return spring 900 is in a compressed state. The sealing gasket 800 is disengaged from the connecting connector assembly 700 that connects to the water purifier inlet, and is used to connect the two connecting connector assemblies 700. When the other end of the sealing rod assembly 500 is disengaged from the snap-fit ​​assembly 400, the second return spring 900 is reset under the action of elasticity, so that the sealing gasket 800 seals the connecting connector assembly 700 that connects to the water purifier inlet.

[0035] During normal operation, pulling the sealing rod assembly 500 compresses the second return spring 900, disengaging the sealing gasket 800 from the connecting connector assembly 700 that connects to the water purifier inlet. The clamp 503 then engages with the slot 402 of the clamping assembly 400, connecting the two connecting connector assemblies 700 through the connecting groove 103. When the expansion assembly 202 encounters water (e.g., due to pipe leakage), the expansion cotton 202 absorbs water and expands, lifting the pressure plate 405. The clamping block 401 rotates around the shaft 403, disengaging the clamp 503 from the slot 402. The second return spring 900 then springs back to its original position, pushing the sealing rod assembly 500 to seal the connecting connector assembly 700, thus cutting off the water flow and preventing leakage. This mechanical linkage enables automatic water flow control and leak prevention, facilitating assembly, maintenance, and component replacement.

[0036] In some embodiments, the sealing rod assembly 500 includes a connecting rod 501 and a sealing rod 505, which are fixedly connected. The connecting rod 501 and the sealing rod 505 are coaxially arranged with the connecting joint assembly 700 that communicates with the water inlet of the water purifier.

[0037] In some embodiments, a plurality of second sealing rings 504 are fitted onto the sealing rod 505, allowing the sealing rod 505 to slide and seal within the connecting groove 103. The sealing rod 505 is slidably connected to one side of the connecting groove 103, and one end of the sealing rod 505 located inside the connecting groove 103 is fixedly connected to the sealing gasket 800. A fourth sealing ring 801 is fitted onto the contact end of the connecting connector assembly 700, which communicates with the water inlet of the water purifier. When the sealing rod 505 slides, the second sealing rings 504 fill the gap between the rod and the connecting groove 103, preventing water leakage. When the sealing gasket 800 seals, the fourth sealing ring 801 is compressed and deformed, filling the gap between the sealing gasket and the connecting connector assembly 700, thus strengthening the seal.

[0038] In some embodiments, a locking head 503 is fixedly installed below the other end of the connecting rod 501. The locking head 503 engages with the locking assembly 400. A pull rod 502 is provided on the connecting rod 501, which is used to pull the connecting rod 501 to slide within the connecting groove 103. Pulling the pull rod 502 causes the connecting rod 501 and the sealing rod 505 to slide along the axis, thereby achieving active control of the sealing rod assembly 500. The locking head 503 moves with the rod and cooperates with the locking assembly 400 to complete self-locking.

[0039] In some embodiments, a cover plate 101 is bolted to one side of the connector body 100 to seal the connecting groove 103. A plurality of first sealing rings 102 are provided at the sealing point between the cover plate 101 and the connector body 100. A second return spring 900 is sleeved on the connecting rod 501 and located inside the connecting groove 103. One end of the second return spring 900 contacts one side of the sealing rod 505, and the other end contacts the inner side of the cover plate 101. The cover plate 101 and the first sealing rings 102 seal the connecting groove 103, preventing water leakage from the side of the connector body 100.

[0040] In some embodiments, the snap-fit ​​assembly 400 includes a snap-fit ​​block 401 with a snap-fit ​​groove 402 on its upper side. The snap-fit ​​head 503 matches the snap-fit ​​groove 402 and is snapped into place inside the groove 402. The snap-fit ​​block 401 is rotatably connected to a mounting bracket 300 via a rotating shaft 403. The mounting bracket 300 is fixedly mounted on a base plate 600. Rotation of the snap-fit ​​block 401 can disengage the snap-fit ​​head 503 from the groove 402. When the snap-fit ​​head 503 is inserted into the groove 402, the snap-fit ​​block 401 rotates slightly around the rotating shaft 403 to achieve a snap-fit. When unlocking is required, the expansion assembly lifts the pressure plate, causing the snap-fit ​​block 401 to rotate in the opposite direction, and the snap-fit ​​head 503 disengages from the groove, releasing the lock. The response is sensitive and rapid.

[0041] In some embodiments, a pressure plate 405 is installed at the other end of the snap-fit ​​block 401. The pressure plate 405 is located above the expansion assembly 200. The expansion assembly 200 includes a frame groove 201 and an expansion cotton 202. The expansion cotton 202 is disposed inside the frame groove 201. The expansion cotton 202 absorbs water and expands, lifting the pressure plate 405, causing the snap-fit ​​block 401 to rotate around the rotating shaft 403. When the pipeline leaks, water seeps into the frame groove 201. The expansion cotton 202 absorbs water and expands, lifting the pressure plate 405 upwards, causing the snap-fit ​​block 401 to rotate around the rotating shaft 403. This causes the snap-fit ​​groove 402 to misalign with the snap-fit ​​head 503, releasing the lock and triggering the sealing action of the second reset spring 900. By utilizing the "active triggering upon contact with water" characteristic of the expansion cotton, an automatic response to leakage is achieved.

[0042] In some embodiments, a first reset spring 404 is provided at the bottom of the snap-fit ​​block 401. The first reset spring 404 is fixedly installed on the base plate 600 and is used to reset the snap-fit ​​block 401.

[0043] In some embodiments, the base plate 600 is provided with a plurality of mounting ears 602 around its perimeter, and the base plate 600 is installed at the water purifier placement location by bolts. The bottom of the base plate 600 is provided with an adhesive block 601 for attaching the base plate 600 to the water purifier placement location.

[0044] In some embodiments, the connecting connector assembly 700 includes a connecting conduit 701, which communicates internally with the connecting groove 103. The upper end of the connecting conduit 701 is provided with a claw 702 for inserting inlet and outlet water pipes. A third sealing ring 704 is engaged with the outer side of the claw 702 to secure the pipe. A retaining ring 703 is provided inside the connecting conduit 701. When the pipe is inserted into the claw 702, the claw is compressed and retracts inward, gripping the pipe tightly; the retaining ring 703 embeds, preventing the pipe from retracting, and together with the third sealing ring 704, achieves a sealed connection between the pipe and the connector.

[0045] Working Principle: In use, a leak-proof self-locking connector structure for water purifier pipes allows the following operation: Pulling the lever 502 slides the sealing rod assembly 500, compressing the second return spring 900, causing the clamp head 503 to engage with the slot 402, and disengaging the sealing gasket 800 from the connecting connector assembly 700. The two connecting connector assemblies 700 are then connected via the connecting groove 103, allowing normal water flow. When the pipe leaks, water enters the frame groove 201, causing the expansion cotton 202 to expand and lift the pressure plate 405. The locking block 401 rotates, disengaging the clamp head 503 from the slot 402, resetting the second return spring 900, and pushing the sealing rod assembly 500. The sealing gasket 800 then seals the connecting connector assembly 700, cutting off the water flow. After the leak is resolved, pulling the lever 502 re-engages the clamp head 503 with the slot 402, disengaging the sealing gasket 800, restoring the water flow, and the locking block 401 resets under the action of the first return spring 404.
