Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of water inlet valves, and particularly relates to a quick-release structure of a water inlet valve. BACKGROUND

[0002] A water inlet valve is a key component for controlling water inlet in bathroom products, water tanks and other equipment. The convenience of its installation, adjustment and maintenance directly affects user experience and production efficiency. The traditional connection mode of the water inlet valve and the water inlet pipe usually adopts threaded connection or simple buckle fixing.

[0003] Although the threaded connection mode is firm, the valve body needs to be rotated multiple times during installation and disassembly, which is tedious and time-consuming to operate, and is extremely inconvenient in a space-limited installation environment. More importantly, when the filter screen of the water inlet valve needs to be cleaned or replaced (the filter screen is installed in the water inlet pipe), the entire water inlet valve must be completely unscrewed, which is time-consuming and laborious.

[0004] The existing part of the quick-release structure realizes disassembly through a simple buckle, which solves the disassembly problem, but usually lacks effective gear division and locking mechanisms. This leads to the valve body being completely separated due to misoperation when only the valve body height needs to be adjusted, causing inconvenience and even installation accidents. SUMMARY

[0005] The purpose of the present application is to provide a quick-release structure of a water inlet valve that can achieve quick release and safely and independently adjust the height, thereby improving the usability and reliability of the product.

[0006] To achieve the above purpose, the solution of the present application is to provide a quick-release structure of a water inlet valve, comprising a valve body, a water inlet pipe and a knob. The valve body is movably sleeved on the water inlet pipe, and the bottom end of the valve body is fixed with at least two elastic members. The outer periphery of the water inlet pipe is provided with at least one height limiting member and one quick-release limiting member matched with the elastic members. The knob is movably sleeved on the valve body, and the inner periphery of the knob is provided with a locking member for locking or unlocking the matching relationship between the elastic members and the height limiting member and the quick-release limiting member. Rotating the knob makes the valve body in at least three gear states, including a first gear, a second gear and a third gear state. In the first gear state, the elastic members are locked with the height limiting member, so that the valve body is locked and fixed with the water inlet pipe. In the second gear state, the elastic members are unlocked with the height limiting member and locked with the quick-release limiting member, so that only the height adjustment of the valve body can be performed. In the third gear state, the elastic members are unlocked with the height limiting member and the quick-release limiting member, so that the height adjustment or disassembly operation of the valve body can be performed.

[0007] Furthermore, the elastic element includes at least one first elastic element and one second elastic element. The inner circumference of the first elastic element is provided with a plurality of first locking teeth, and the height limiting element is a plurality of toothed grooves arranged along the axial direction of the water inlet pipe. The inner circumference of the second elastic element is provided with second locking teeth, the quick-release limiting element is a limiting rib, and the locking element is a limiting boss radially protruding from the inner circumference of the knob. In the first position, the limiting boss is attached to the outer periphery of the first elastic member to radially compress the first elastic member, causing the first locking tooth to engage and lock with the tooth groove; in the second position, the limiting boss disengages from the first elastic member and attaches to the outer periphery of the second elastic member to unlock the first locking tooth and tooth groove, and radially compresses the second elastic member, causing the second locking tooth to engage with the limiting rib to prevent the valve body from disengaging from the inlet pipe; in the third position, the limiting boss separates from both the first and second elastic members, and both the first and second elastic members are unlocked.

[0008] Furthermore, the outer periphery of the water inlet pipe is provided with at least one first groove and one second groove along the axial direction. The tooth groove is disposed in the first groove, and the first locking tooth engages in the first groove. The top of the second groove is provided with a limiting rib, and the second locking tooth engages in the second groove.

[0009] Furthermore, the bottom outer periphery of the valve body is provided with a first annular groove, and the inner periphery of the knob is provided with at least one limiting slider, which is movably fitted within the first annular groove.

[0010] Furthermore, the outer periphery of the valve body is provided with a second annular groove above the first annular groove. A torsion spring is sleeved on the second annular groove, and a retaining groove is provided at the top of the second annular groove. One end of the torsion spring is engaged with the retaining groove, and the other end is engaged with one side of the limiting slider.

[0011] Furthermore, the top of the limiting slider is an inclined surface, and at least one inclined groove is provided between the first annular groove and the bottom end of the valve body. The inclined groove is connected to the first annular groove, and the inclined surface of the limiting slider slides into the inclined groove so that the limiting slider slides upward into the first annular groove.

[0012] Furthermore, the bottom of the valve body is provided with a body spring buckle, the bottom of the body spring buckle is integrally provided with an elastic element extending downward, the bottom end of the valve body is provided with at least one fixing buckle extending downward, and the top of the body spring buckle is provided with a buckle hole that cooperates with the fixing buckle.

[0013] Furthermore, the bottom of the knob is provided with an annular limiting step, which engages with the bottom end of the elastic element to limit the spring-loaded body from disengaging from the valve body.

[0014] Furthermore, the valve body has at least three position markings on its outer periphery, and the knob has a positioning mark on its outer periphery. When the knob is rotated to the three position positions in sequence, the positioning mark aligns with the three position markings in sequence.

[0015] Furthermore, the valve body is provided with a water outlet channel communicating with the water inlet pipe. The water outlet channel is provided with a noise reduction structure, which includes a ring and several flow straightening ribs. The ring is located at the center of the water inlet and outlet channel, and the ring is connected to the inner wall of the water outlet channel through the flow straightening ribs.

[0016] After adopting the above solution, the beneficial effects of the present invention are as follows: This invention achieves three adjustable positions by using a height limiting component, a quick-release limiting component, and an elastic component. The position can be selected by rotating a knob, allowing for selective adjustment. In the first position, the valve body is locked in place; this is the original state. In the second position, only the height of the valve body can be adjusted, but it cannot be disassembled, enabling precise height adjustment without disassembly. This greatly simplifies installation and subsequent maintenance, preventing inconvenience and installation accidents caused by accidental valve detachment. In the third position, both the valve body height can be adjusted and the valve body can be disassembled for easy filter replacement without completely unscrewing the entire inlet valve, saving time and effort during assembly and disassembly.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] like Figures 1-20As shown, this application provides a quick-release structure for a water inlet valve, including a valve body 1, a water inlet pipe 2, and a knob 3. The valve body 1 is movably sleeved on the water inlet pipe 2, and at least two elastic elements are fixed at the bottom end of the valve body 1. The outer periphery of the water inlet pipe 2 is provided with at least one height limiting element 21 and one quick-release limiting element 22 that cooperate with the elastic elements. The elastic element can be a spring sheet, and the spring sheet has a structure that cooperates with the height limiting element 21 and the quick-release limiting element 22. Of course, the elastic element can also be an elastic buckle, an elastic tooth, or other elastic structure. The knob 3 is movably sleeved on the valve body 1, and the inner periphery of the knob 3 is provided with a locking element 31. The locking element 31 is used to lock or unlock the cooperation relationship between the elastic element and the height limiting element 21 and the quick-release limiting element 22. The locking element 31 restricts the elastic deformation ability of the elastic element so that the elastic element cannot be disengaged from the height limiting element 21 and the quick-release limiting element 22, thereby achieving locking. Specifically, rotating knob 3 can put valve body 1 into at least three positions, including the first position, the second position, and the third position.

[0021] In the first position, the elastic element and the height limiting element 21 are locked, thus locking the valve body 1 and the water inlet pipe 2. At this time, the valve body 1 cannot be separated from the water inlet pipe 2, and the valve body 1 cannot move up or down relative to the water inlet pipe 2 for height adjustment. That is, the first position is the locking position, generally the original position. In the second position, the elastic element and the height limiting element 21 are unlocked, and the valve body 1 is locked with the quick-release limiting element 22. At this time, moving the valve body 1 up or down allows for height adjustment, but the quick-release limiting element 22 is still locked with the elastic element. The valve body 1 is locked in place and cannot be disassembled. Only the height of the valve body 1 can be adjusted, which realizes the function of precise height adjustment without disassembly. This greatly facilitates installation and subsequent maintenance and avoids the inconvenience and installation accidents caused by the valve body 1 being completely detached due to misoperation. Thus, the second position is the height adjustment position. In the third position, the elastic element, the height limit element 21, and the quick-release limit element 22 are all unlocked. At this time, the height of the valve body 1 can be adjusted or disassembled. That is, the third position is the quick-release adjustment position.

[0022] Key references Figures 8-10The elastic element includes at least one first elastic element 41 and one second elastic element 42. Both the first elastic element 41 and the second elastic element 42 are spring sheet structures. The inner circumference of the first elastic element 41 is provided with a plurality of first locking teeth 411. The height limiting element 21 is a plurality of toothed grooves arranged axially along the water inlet pipe 2. The first locking teeth 411 mesh with the toothed grooves. The inner circumference of the second elastic element 42 is provided with at least one second locking tooth 421. The quick-release limiting element 22 is a limiting rib. The limiting rib is preferably located at a higher position at the top of the water inlet pipe 2. The second locking tooth 421 is located below the limiting rib to engage with the limiting rib vertically to achieve locking. The locking element 31 is a limiting boss radially protruding from the inner circumference of the knob 3. Rotating the knob 3 can switch the valve body 1 to three gear positions, as detailed below: In the first gear position, the limiting boss is attached to the outer periphery of the first elastic member 41, radially pressing the first elastic member 41 and limiting its elastic deformation ability. This prevents the first elastic member 41 from loosening its tooth groove under tension, and instead presses the first locking tooth 411 against the tooth groove, locking them together. As a result, the valve body 1 is in a locked state and cannot move up or down relative to the inlet pipe 2. Furthermore, the limiting boss can only lock one elastic member at a time. At this time, the second elastic member 42 is in an unlocked state, but since the first elastic member 41 has already locked the valve body 1, unlocking the second elastic member 42 will not affect the locking in the first gear position. In addition, the number of the first locking teeth 411 is preferably set to multiple. The meshing of multiple first locking teeth 411 with multiple tooth grooves is a multi-point locking method with surface contact, which far exceeds the locking force and vibration resistance of traditional single-point buckles. It can effectively resist water pressure fluctuations and impacts in the water supply network, and ensure that the connection between the valve body 1 and the water inlet pipe 2 is absolutely firm in the working state, thereby ensuring long-term sealing reliability and eliminating the risk of water leakage.

[0023] When the knob 3 is rotated to the second position, the limiting boss disengages from the first elastic member 41 and engages with the outer periphery of the second elastic member 42. At this time, the first elastic member 41 recovers its elastic deformation capability, which unlocks the first locking tooth 411 and the tooth groove. Pulling the valve body 1 up and down allows the first locking tooth 411 to disengage from the original tooth groove and engage with other tooth grooves of different heights to achieve height adjustment. At the same time, the limiting boss radially presses the second elastic member 42 to limit the elastic deformation capability of the second elastic member 42. When the valve body 1 is adjusted to the highest height, the second locking tooth 421 engages with the limiting rib to prevent the valve body 1 from disengaging from the inlet pipe 2. Therefore, the valve body 1 can only be adjusted in height in this position and cannot be quickly disassembled.

[0024] Continue rotating knob 3 to the third position. In this position, the limiting boss separates from both the first elastic element 41 and the second elastic element 42, allowing both elastic elements 41 and 42 to unlock and regain their elastic deformation capability. At this time, not only can the valve body 1 be pulled up and down to adjust the height, but pulling the valve body 1 upwards can also disengage the second locking tooth 421 from the limiting rib, thus achieving the disassembly of the valve body 1 from the water inlet pipe 2. Figures 11-13 As shown, after disassembling the valve body 1, the filter screen 6 can be removed from the inlet pipe 2 for replacement. After replacement, keep the knob 3 in the third position, then put the valve body 1 on the inlet pipe 2, and then turn the knob 3 to the first position to lock the valve body 1. This completes the disassembly and replacement of the filter screen 6, which is convenient and quick.

[0025] It should be noted that the locking element 31 is not limited to a limiting boss, but can also be an unlocking groove structure on the inner circumference of the knob 3. When the knob 3 is rotated until the elastic element is in the unlocking groove, the elastic element restores its elastic deformation ability to unlock. When the elastic element disengages from the unlocking groove, it is locked by the inner circumference of the knob 3. The height limiting element 21 and quick-release limiting element 22, in addition to the toothed groove and limiting rib, can also be other fastening structures that cooperate with the elastic element; this is not limited in this case. Furthermore, in addition to the above three positions, an elastic element can be added to achieve other position settings.

[0026] Specifically, the outer periphery of the water inlet pipe 2 is provided with at least one first groove 23 and one second groove 24 along the axial direction. The toothed groove is disposed in the first groove 23. The first locking tooth 411 is engaged in the first groove 23 and will not dislodge from the first groove 23. Thus, the first locking tooth 411 can only move up and down in the first groove 23 to engage with the toothed groove. The top of the second groove 24 is provided with a limiting rib. The second locking tooth 421 is engaged in the second groove 24 and is located below the limiting rib. Similarly to the first locking tooth 411, the second locking tooth 421 can only move up and down in the second groove 24.

[0027] Preferably, the first elastic element 41, the second elastic element 42, the first groove 23, the second groove 24, and the limiting boss are all symmetrically provided in two sets to increase the stability of the locking valve body 1 and the stability of the height adjustment.

[0028] Specifically, the valve body 1 has a first annular groove 11 on its bottom outer periphery, and the knob 3 has at least one limiting slider 32 protruding radially on its inner periphery. The limiting slider 32 is movably fitted within the first annular groove 11 and can slide circumferentially along the first annular groove 11 to allow the limiting slider 32 to rotate and be sleeved on the valve body 1. A stop rib 111 can also be provided within the first annular groove 11. When the knob is rotated to the third position or returned to the first position, the stop rib 111 abuts against the limiting slider 32 to restrict further rotation of the knob 3.

[0029] Preferably, the top of the limiting slider 32 is an inclined surface, and at least one inclined groove 13 is provided between the first annular groove 11 and the bottom end of the valve body 1. The inclined groove 13 communicates with the first annular groove 11, and the inclined surface of the limiting slider 32 can slide in cooperation with the inclined groove 13. That is, when installing the knob 3, the limiting slider 32 can be aligned with the inclined groove 13, and then the knob 3 can be pushed up to allow the limiting slider 32 to slide through the inclined groove 13 into the first annular groove 11, thereby achieving quick installation of the knob 3. Both the limiting slider 32 and the inclined groove 13 can be symmetrically arranged in two sets.

[0030] The elastic element can be integrally disposed on the bottom of the valve body 1 or separately disposed. In this embodiment, the elastic element and the valve body 1 are separately disposed. For details, please refer to [link / reference needed]. Figures 6-8 The valve body 1 has an annular snap fastener 4 at its bottom. An elastic element extends downwards integrally from the bottom of the snap fastener 4. At least one fixing buckle 14 extends downwards from the bottom end of the valve body 1. The top of the snap fastener 4 has a buckle hole 43 that engages with the fixing buckle 14. The snap fastener 4 is fixed to the bottom of the valve body 1 by the engagement of the fixing buckle 14 and the buckle hole 43, facilitating its installation and removal. The knob 3 has an annular limiting step 33 at its bottom. This limiting step 33 engages with the bottom end of the elastic element, further preventing the snap fastener 4 from disengaging from the valve body 1.

[0031] The outer periphery of the valve body 1 is provided with at least three position markings 15, such as Figures 1-2 As shown, from left to right are the first gear position marking, the second gear position marking, and the third gear position marking. A positioning mark 34 is provided on the outer periphery of the knob 3. When the knob 3 is rotated clockwise to the three gear positions in sequence, the positioning mark 34 aligns with the three gear position markings 15 in sequence. The gear position markings 15 and the positioning mark 34 provide the user with intuitive and accurate operation guidance.

[0032] Furthermore, the valve body 1 is provided with a housing 16 on its outer periphery. The gear position mark 15 is located on the bottom end of the housing 16, and the positioning mark 34 is located on the top end of the knob 3. When the knob 3 is installed on the valve body 1, the top end of the knob 3 abuts against the bottom end of the housing 16, so that the gear position mark 15 and the positioning mark 34 fit together vertically, which can achieve clear gear position guidance operation.

[0033] Key participants Figures 3-7 In one embodiment, a torsion spring 5 is provided between the knob 3 and the valve body 1. After the valve body 1 is adjusted to the required position or the filter screen 6 is replaced and the valve body 1 is reinstalled, the knob 3 is released. The knob 3 will automatically return to the first gear position under the force of the torsion spring 5, realizing self-locking. The design of the knob 3 effectively avoids the risk of failure caused by human factors when the water inlet valve is adjusted in height.

[0034] Specifically, the outer periphery of the valve body 1 is provided with a second annular groove 12 above the first annular groove 11. A torsion spring 5 is sleeved on the second annular groove 12. A retaining groove 17 is provided at the top of the second annular groove 12. One end of the torsion spring 5 is engaged with the retaining groove 17, and the other end is engaged with one side of the limiting slider 32. Rotating the knob 3 can stretch the torsion spring 5. Releasing the knob 3 can cause the torsion spring 5 to drive the knob 3 to reset.

[0035] Key references Figures 11-16 In another embodiment, instead of a torsion spring 5 and a second annular groove 12, a vertical groove 18 for warning purposes is provided between the knob 3 and the valve body 1. The vertical groove 18 communicates with the first annular groove 11. The limiting slider 32 slides with the vertical groove 18 to replace the function of the inclined groove 13. In the third gear position, the limiting slider 32 is located at the top of the vertical groove 18. After disassembling and assembling the valve body 1 and releasing the knob 3, the limiting slider 32 moves downward along the vertical groove 18, leaving a gap between the knob 3 and the outer casing 16. The presence of this gap reminds the operator that the knob 3 has not been reset and needs to be pushed up and rotated to the first gear position to reset.

[0036] Key references Figure 16 As shown, a limiting protrusion 44 is provided on the top of the outer periphery of the first elastic member 41 or the second elastic member 42, and a vertical groove 18 is provided to be aligned vertically with the first elastic member 41 or the second elastic member 42. After the limiting slider 32 slides to the vertical groove 18, the limiting protrusion 44 can prevent the limiting slider 32 from disengaging from the valve body 1. The body spring buckle 4 is provided with a limiting groove 45 communicating with the vertical groove 18 above the limiting protrusion 44. After the limiting slider 32 slides to the vertical groove 18, it will slide down to the position of the limiting groove 45 and cooperate with the limiting protrusion 44 to achieve limiting.

[0037] The annular groove is provided with a first gear slot 112, a second gear slot 113, and a third gear slot 114 sequentially along its circumferential direction. When the knob is rotated to the first, second, and third gear positions, the limiting slider 32 is located within the first gear slot 112, the second gear slot 113, and the third gear slot 114. This arrangement allows the limiting slider 32 to remain within the corresponding gear slot in the corresponding gear position, facilitating operation. Two sets of gear slots and limiting sliders 32 can be provided. The third gear slot 114 is located above the vertical groove 18. Stopping ribs 111 are provided on the outer sides of the first and third gear slots 112 and 114. The inner surfaces of the first and third gear slots 112 and the two sides of the second gear slot 113 are all inclined surfaces to facilitate the sliding engagement of the limiting slider 32 to slide out of the corresponding gear slot.

[0038] Key references Figures 17-20The valve body 1 is provided with a water outlet channel 8 that is connected to the water inlet pipe 2. The water outlet channel 8 is provided with a noise reduction structure 7. The noise reduction structure 7 can integrate the water flow into a soft water column that falls into the water surface in the water tank, effectively reducing the noise generated by the water flow falling into the water surface.

[0039] Specifically, the noise reduction structure 7 includes a circular ring 71 and several rectifier ribs 72, such as... Figure 20 As shown, four flow-rectifying ribs 72 are preferably provided. The circular ring 71 is located at the center of the inlet / outlet channel 8, and the circular ring 71 is connected to the inner wall of the outlet channel 8 by the flow-rectifying ribs 72. The outlet channel 8 includes a water intake section 81, a flow-rectifying section 82, and an outlet section 83. The water intake section 81 and the outlet section 83 are located above and below the noise reduction structure 7, respectively. The flow-rectifying section 82 is located at the position of the noise reduction structure 7. The water flows out of the outlet channel 8 after passing through the water intake section 81, the flow-rectifying section 82, and the outlet section 83 in sequence. The water flow inside the water intake section 81 is in a turbulent state. When the water flows through the rectifying section 82, the increased contact area of ​​the water flow due to the ring 71, rectifying ribs 72, and the inner wall of the outlet channel within the rectifying section causes the turbulent water flow to flow down the wall, rectifying the turbulent flow with inconsistent velocities into a flow with similar velocities, thus stabilizing the water flow. The stable water flow then converges through the outlet section 83, forming a gentle water column that falls onto the water surface. The gentle water flow has a relatively low velocity and a smoother contact with the water surface, reducing the generation of turbulent vortices and avoiding the sound waves generated by bubble bursting (cavitation noise) and the impact of splashing droplets. In addition, the height of the ring 71 and rectifying ribs 72 can be set to be relatively long to lengthen the rectifying section 82 and improve the rectification effect, which can be set according to actual needs.

[0040] Furthermore, the outer casing 16 includes a top cover 161 and a water stop cup 162. The water outlet channel 8 is located inside the water stop cup 162. The valve body 1 is provided with a water outlet 19 that communicates with the water inlet pipe 2. The water outlet 19 is sealed to the water inlet section 81, specifically through a sealing ring. That is, the water flows through the water inlet pipe 2 to the valve body, and then flows into the water inlet section 81 through the water outlet 19 of the valve body 1. After being rectified by the rectifier section 82, it flows out from the water outlet section 83 into the water tank, achieving rectification and noise reduction, and avoiding the water outlet height being too high, which would cause the water to fall into the water surface and generate noise, affecting the user experience.
