[0037] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0038] like Figures 1-3As shown, according to one aspect of this utility model, an easily replaceable and repairable valve body structure is provided, including a base box 200 and a valve body 100. The valve body 100 is detachably installed inside the base box 200, and also includes a connecting member 300 communicating with the valve body 100 and a drain pipe 400. The connecting member 300 is detachably connected to the base box 200, and the connecting member 300 is movable relative to the valve body 100; or the connecting member 300 is detachably connected to the valve body 100, and the connecting member 300 is movable relative to the base box 200; the connecting member 300 can move away from or towards the valve body 100, thereby allowing the valve body 100 to detach from the base box 200; the peripheral wall of the connecting member 300 is provided with a plurality of through holes 340 communicating with the outside atmosphere, serving as an anti-siphon function. The plurality of through holes 340 can be arranged circumferentially at the same height. A one-way valve or an anti-siphon pad 610 is provided inside the connecting member 300. Both the one-way valve and the anti-siphon pad 610 can prevent liquid or debris from flowing back into the valve body 100, thus providing an anti-siphon function. The anti-siphon pad 610 is detachably installed within the connecting member 300. Compared to traditional one-way valves, the anti-siphon pad 610 has a simpler structure, lower cost, and is easier to install and maintain. The anti-siphon pad 610 can also be integrated with the connecting member 300.

[0039] Understandably, the valve body 100 is connected and communicates with the drain pipe 400 via the connecting member 300. The detachable connection structure between the connecting member 300 and the valve body 100 or the base box 200 can be an existing threaded connection, snap-fit ​​connection, or binding connection. The connecting member 300 allows movement away from or towards the valve body 100, enabling the valve body 100 to detach from the base box 200. This facilitates further disassembly and removal of the valve body 100 from the wall or equipment, reducing the difficulty of disassembly, maintenance, and replacement of the valve body 100, improving disassembly efficiency, and reducing maintenance costs.

[0040] Specifically, in some embodiments, the connecting member 300 and the base box 200 or valve body 100 form a telescopic, detachable sleeve structure. In operation, both ends of the connecting member 300 are connected to the base box 200 and the valve body 100, respectively. When the valve body needs to be disassembled, one end of the connecting member 300 is first disconnected, restoring the connecting member 300 and the base box 200 or valve body 100 to a telescopic state. The telescopic movement of the connecting member 300 makes disassembling and removing the valve body 100 much simpler.

[0041] In some embodiments, as Figure 2 As shown, the anti-siphon pad 610 has a support frame 620 inside. It can be understood that when the anti-siphon pad 610 is made of elastic material, the support frame 620 can support the inside of the anti-siphon pad 610, prevent the anti-siphon pad 610 from collapsing inward, and maintain the smooth flow of water from the anti-siphon pad 610.

[0042] In some embodiments, as Figure 4As shown, the anti-siphon pad 610 has an upper suction pad extension 611, and the inner side of the suction pad extension 611 has a groove 612. The support frame 620 has an upper support frame extension 621, which is located within the groove 612. It can be understood that the groove 612 of the suction pad extension 611 locks and limits the support frame extension 621, preventing the support frame 620 from shifting or deforming, thus improving the overall integrity of the anti-siphon pad 610 and the support frame 620 and maintaining a consistently high working efficiency.

[0043] In some embodiments, as Figure 4 As shown, an O-ring 310 is provided on the outer periphery of the connecting member 300 inside the socket 500. It can be understood that the O-ring 310 is used to seal the gap between the connecting member 300 and the socket 500, thereby achieving a waterproof effect.

[0044] In some embodiments, as Figures 1-3 As shown, the anti-siphon pad 610 is fitted onto the connecting member 300 at its front end and has a closed opening at its rear end. The anti-siphon pad 610 is made of elastic material. It can be understood that the lower part of the anti-siphon pad 610 is a constricted funnel shape. When water flows from the valve body 100 towards the drain pipe 400, the water flow impacts the wide opening of the anti-siphon pad 610, opening it and allowing water to pass through. When negative pressure is generated in the pipe, due to the through hole 340, outside air can enter the pipe through the through hole 340, preventing siphon formation and achieving backflow prevention.

[0045] In some embodiments, as Figures 3-6 As shown, the base box 200 is equipped with a socket 500, and the connecting piece 300 connects the outlet connector 110 of the valve body 100 and the socket 500. Specifically, as... Figure 2 As shown, the connecting member 300 is slidably connected to the upper part of the sleeve 500, and the lower part of the sleeve 500 is connected to the end of the drain pipe 400. It can be understood that the lower part of the sleeve 500 and the end of the drain pipe 400 can be connected by any existing pipe fitting method such as adhesive bonding or snap-fitting. In this embodiment, a lower nut 520 is used for connection, and a sealing element 550 is provided inside the lower nut 520. Specifically, the portion of the connecting member 300 connected to the sleeve 500 slides for a certain length without disengaging from the sleeve 500. The lower nut 520 screws onto the sleeve 500, causing it to have an interference fit with the end of the drain pipe 400, thereby locking the drain pipe 400.

[0046] In some embodiments, as Figures 1-3As shown, the connecting piece 300 is detachably connected to the outlet connector 110 of the valve body 100. After the connecting piece 300 is detached from the outlet connector 110 of the valve body 100, the connecting piece 300 can telescopically connect with the sleeve 500. After the connecting piece 300 is detached from the valve body 100, it retracts into the sleeve 500, so that the upper end of the connecting piece 300 avoids the valve body 100, making it easier to remove the valve body 100.

[0047] In some embodiments, as Figure 2 As shown, a stop 510 is provided between the connecting member 300 and the end of the drain pipe 400 within the socket 500. It can be understood that the upper side of the stop 510 supports the connecting member 300, restricting its downward movement within the socket 500. The stop 510 presses against the end of the drain pipe 400, strengthening the connection and limiting relationship between the socket 500 and the end of the drain pipe 400. The stop 510 can be any shape that achieves a blocking and limiting effect, such as a retaining ring or a stop block.

[0048] In some embodiments, as Figures 1-3 As shown, the socket 500 passes through the wall 210 of the base box 200. The outer periphery of the socket 500 is provided with a platform 530 and external threads. The platform 530 is located on the upper side of the wall 210 of the base box 200. The socket 500 on the lower side of the wall 210 of the base box 200 is provided with a locking nut 540. It can be understood that in this embodiment, the valve body 100 is located inside the base box 200. The upper and lower parts of the base box 200 are respectively provided with an inlet pipe 700 and a drain pipe 400. The ends of the inlet pipe 700 and the drain pipe 400 are respectively provided with quick connectors, which are detachably connected to the inlet connector 120 and the outlet connector 110 of the valve body 100. The valve body 100 is also provided with a controller for controlling the connection and disconnection of the inlet and outlet ends.

[0049] In some embodiments, as Figures 2-3 As shown, the device includes a fastener 330 externally connected to the connecting member 300. The fastener 330 has an internal thread and a step 331 on its lower inner side. The connecting member 300 has a connecting extension 320 on its outer periphery, located above the step 331. The connecting extension 320 abuts against the step 331, so that when the fastener 330 is screwed onto the water outlet connector 110 of the valve body 100, the connecting member 300 can move closer to the valve body 100 and ultimately lock and fix itself onto the valve body 100. In other embodiments, the threaded connection portion is integrally formed with the connecting member 300.

[0050] In some embodiments, as Figures 1-4As shown, the suction pad extension 611 and / or the connecting extension 320 are pressed between the step 331 and the water outlet connector 110 of the valve body 100. It can be understood that after the suction pad extension 611 and the connecting extension 320 are pressed together, the connecting part 300, the anti-siphon pad 610 and the internal support frame 620 are all fixed, preventing them from colliding, losing or deforming after water is supplied, and ensuring the working stability and service life of each component.

[0051] In other embodiments, such as Figures 7-8 As shown, the connecting member 300 and the socket 500 are detachably connected. After the connecting member 300 is detached from the socket 500, it can telescopically connect with the outlet connector 110 of the valve body 100. It can be understood that the connecting member 300 can move close to the valve body 100; that is, after the connecting member 300 is detached from the socket 500, it retracts into the valve body 100, causing the lower end of the connecting member 300 to avoid the socket 500 or the base box 200, thereby allowing the valve body 100, together with the connecting member 300, to detach from the base box 200.

[0052] In some embodiments, the connecting member 300 is detachably connected to the socket 500 or the water outlet connector 110 by a fastener 330; or, the connecting member 300 is detachably connected to the socket 500 or the water outlet connector 110 by a snap-fit ​​connection; or, the connecting member 300 is detachably connected to the socket 500 or the water outlet connector 110 by a threaded connection. In this embodiment, as... Figures 1-3 As shown, the connecting member 300 is detachably connected to the socket 500 by the fastener 330. At this time, the connecting member 300 is slidably connected to the socket 500, as detailed above.

[0053] In some embodiments, the connecting member 300 is integrated with or separate from the one-way valve, or the connecting member 300 is integrated with or separate from the anti-siphon pad 610.

[0054] In some embodiments, as Figure 2 As shown, the valve body 100 is provided with a water inlet connector, and the base box 200 is also provided with a water inlet pipe 700. The water inlet connector 120 is detachably connected to the water inlet pipe 700. The base box 200 has an operation window 220. When disassembled, the connecting piece 300 can move away from or close to the valve body 100, so that the valve body 100 can be separated from the base box 200 from the operation window 220.

[0055] For ease of understanding, this application also provides a more specific implementation method:

[0056] like Figures 1-6As shown, one embodiment of this application provides an easily replaceable and repairable valve body structure, including a base box 200, within which a valve body 100 is housed. The base box 200 has an inlet pipe 700 and a drain pipe 400 respectively located at its upper and lower parts. Quick connectors are provided at the ends of the inlet pipe 700 and the drain pipe 400, respectively detachably connecting to the inlet connector 120 and the outlet connector 110 of the valve body 100. A sleeve 500 is provided on the lower wall 210 of the base box 200, within which a slidable connecting member 300 is provided. The upper part of the connecting member 300 is detachably connected to the outlet connector 110 of the valve body 100, specifically by fastening it to the outlet connector 110 of the valve body 100 with a fastener 330; the sleeve 500 is internally connected to the connecting member 300.

[0057] One embodiment of this application operates as follows: During installation, the inlet connector 120 of the valve body 100 is locked onto the base box 200, the connecting member 300 is fitted inside the sleeve 500, and then the connecting member 300 is locked onto the outlet connector 110 of the valve body 100 to complete the valve body installation; during disassembly, the fastener 330 is loosened, causing the connecting member 300 to detach from the outlet connector 110 of the valve body 100, and the connecting member 300 retracts into the sleeve 500 in a direction away from the valve body 100. Then, the inlet connector 120 of the valve body 100 is removed from the base box 200, and the user can then remove the valve body 100 through the operating window 220 on the base box 200. This reduces the difficulty of valve body disassembly, maintenance, and replacement, improves disassembly efficiency, and reduces maintenance costs. The connecting member 300 is provided with a through hole 340 for external atmospheric connection and a one-way valve or anti-siphon pad 610, which effectively prevents backflow of liquid or debris. The structure is simple and the cost is low.

[0058] In other embodiments, such as Figure 7 and Figure 8 As shown, the connecting member 300 can move close to the valve body 100, thereby allowing the valve body 100 to detach from the bottom box 200. Specifically, the connecting member 300 is detachably connected to the sleeve 500. At this time, the water outlet connector 110 of the valve body 100 and the sleeve 500 are threadedly locked by the fastener 330 on the outer periphery, and the connecting member 300 is slidably connected to the water outlet connector 110. During disassembly, the fastener 330 is unscrewed, and the connecting member 300 can detach from the sleeve 500 and retract close to the water outlet connector 110 of the valve body 100, causing the connecting member 300 to detach from the sleeve 500, thereby allowing the valve body 100 together with the connecting member 300 to detach from the bottom box 200.
