Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to faucet devices. Background Technology

[0002] Most existing Roman bathtub faucet systems use a full brass body, requiring a decorative cover or fastening nut to be installed on the countertop before tightening the mounting nut underneath. This type of faucet system is expensive and heavy, and can be inconvenient for installers, especially when facing limited space under the countertop.

[0003] Therefore, there is a certain demand in the industry for improvements to this type of faucet device. These improved faucet devices are expected to reduce costs while ensuring the overall structural strength, and also simplify the installation process to improve assembly efficiency. Summary of the Invention

[0004] The present invention aims to provide a faucet device that can at least solve some of the above-mentioned technical problems.

[0005] According to one aspect of the present invention, a faucet device is provided, comprising: a first body assembly including a polymer inner tube, a first metal sleeve fitted onto the polymer inner tube, and a first pipe connector connected to the polymer inner tube, wherein the first pipe connector has a first inlet pipe section and a first outlet pipe section, the first outlet pipe section being in fluid communication with the polymer inner tube; a second body assembly including a polymer core tube, a polymer outer tube fitted onto the polymer core tube, a second metal sleeve fitted onto the polymer outer tube, and a second pipe connector connected to the polymer outer tube, wherein a fluid channel is formed between the polymer core tube and the polymer outer tube, the second pipe connector having a second inlet pipe section and a second outlet pipe section, wherein the second inlet pipe section is in fluid communication with the polymer core tube, the second outlet pipe section is in fluid communication with the fluid channel, and the second outlet pipe section is in fluid communication with the first inlet pipe section of the first pipe connector; wherein the second body assembly has a valve core at the end opposite to the second pipe connector, the inlet of the valve core being in fluid communication with the polymer core tube, and the outlet of the valve core being in fluid communication with the fluid channel.

[0006] The faucet unit provided in this solution employs a unique water circuit design that nests a polymer core tube and a polymer outer tube to form inner and outer water chambers. This optimizes the water flow path and spatial layout, and is further reinforced with a metal sleeve structure. This significantly reduces manufacturing costs (e.g., by reducing the amount of precious metals used and simplifying the process) while ensuring the structural strength and installation stability of the faucet unit. The water flow channel, made of polymer materials such as plastics, effectively prevents the leaching of heavy metals, improving the health and safety of water use. Furthermore, the inherent low thermal conductivity of the polymer material provides insulation and prevents scalding. In addition, the modular design of the main body assembly (first and second main body assemblies) facilitates assembly and maintenance. The overall structure achieves superior economy and environmental friendliness while maintaining the product's metallic texture and aesthetics.

[0007] In some embodiments, the polymer core tube has an external thread at one end, and the valve core is inserted into the polymer core tube at that end. The second body assembly also includes a top cover with an internal thread, which presses against the valve core and engages with the polymer core tube threadedly.

[0008] In some embodiments, the faucet device further includes a water spout and a coupling seat fixedly connected to the water spout, the coupling seat being located in the first body assembly, and the water spout being in fluid communication with the polymer inner tube.

[0009] In some embodiments, the first pipe connector and the polymer inner tube, and the second pipe connector and the polymer outer tube are respectively connected by retaining rings. With the pre-designed quick-release connection structure, during terminal installation, the pipe connection to the faucet body only needs to be completed below the countertop, eliminating the need for overhead workspace, effectively simplifying the installation process and improving assembly efficiency.

[0010] In some embodiments, the retaining ring has a hook at one end, allowing it to be detachably connected to a corresponding pipe fitting via the hook and rotate relative to the fitting about the connection point. Thanks to the rotatable snap-fit ​​installation design, the under-seat connecting pipe is less prone to folding or twisting.

[0011] In some embodiments, the retaining ring has a fastening portion formed at the other end, and the corresponding pipe fitting has a slot to receive the fastening portion. After the fastening portion is pressed into the slot, the retaining ring clamps the polymer inner tube or the polymer outer tube.

[0012] In some embodiments, the retaining ring has a thickened portion on the side near the hook portion. After the fastening portion is pressed into the corresponding pipe fitting's latch, the thickened portion abuts against the polymer inner tube or the polymer outer tube to clamp the tube.

[0013] In some embodiments, the outer periphery of the retaining ring has a protrusion that extends obliquely away from the hook.

[0014] In some embodiments, the first inlet pipe section of the first pipe connector and the second outlet pipe section of the second pipe connector each have external threads, and the faucet device further includes a hose with internal threads at both ends to fluidly connect the first pipe connector and the second pipe connector.

[0015] In some embodiments, the polymer inner tube and the first metal sleeve, the valve core and the polymer core tube, the polymer core tube and the polymer outer tube, and the polymer outer tube and the second metal sleeve are detachably connected by protrusions and slots.

[0040] Figure 1 An exemplary faucet device 1 according to the present invention is shown. The faucet device 1 includes a first body assembly 3 connected to a water spout 2 and a second body assembly 5 connected to a handle 4, wherein the first body assembly 3 and the second body assembly 5 are connected by a hose 7.

[0041] Figures 2 to 4 The configuration of the first body assembly 3 and its connection with the water tap 2 are shown. As shown, the first body assembly 3 includes a polymer inner tube 34 and a first metal sleeve 35, wherein the inner bore of the polymer inner tube 34 forms a fluid passage for the first body assembly 3. The polymer inner tube 34 is, for example, a plastic tube, and its outer surface portion that engages with the first metal sleeve 35 has multiple convex ridges extending circumferentially and axially, which intersect to form a grid structure. The first metal sleeve 35 can be fitted over the polymer inner tube 34 and fits tightly against the grid structure on the outer surface of the polymer inner tube 34, which helps to increase the coefficient of friction between the polymer inner tube 34 and the first metal sleeve 35 and prevents the first metal sleeve 35 from accidentally slipping off the polymer inner tube 34. To facilitate the assembly of the polymer inner tube 34 and the first metal sleeve 35 together, a convex-concave mating insertion structure can be formed between the polymer inner tube 34 and the first metal sleeve 35. In the illustrated embodiment, the polymer inner tube 34 has an axially extending first protrusion 341, while the first metal sleeve 35 has a first slot 351. By inserting the first protrusion 341 into the first slot 351, the polymer inner tube 34 can be securely connected to the first metal sleeve 35.

[0042] A first pressure cap 33 can also be provided for the first body assembly 3. The first pressure cap 33 has internal threads, while the first metal sleeve 35 has external threads. After the polymer inner tube 34 is inserted into the first metal sleeve 35, the radial protrusion at the first end of the polymer inner tube 34 can block the end of the first metal sleeve 35. Then, the first pressure cap 33 is fitted onto the polymer inner tube 34 from the first end, and the internal step of the first pressure cap 33 presses against the radial protrusion of the polymer inner tube 34. The first pressure cap 33 can be threadedly engaged with the first metal sleeve 35. In this way, the polymer inner tube 34 is pressed between the first pressure cap 33 and the first metal sleeve 35.

[0043] To connect the water nozzle 2 to the first body assembly 3, a connecting seat 31 can be provided between the water nozzle 2 and the first body assembly 3 as a transition structure. As shown in the figure, the connecting seat 31 is connected to the water nozzle 2 by a fastener 32, such as a bolt, and then the connecting seat 31 is placed on the first pressure cap 33. Because the connecting seat 31 adopts a multi-step structure with a gradually expanding outer diameter, it has a large depth in the axial direction. The end of the connecting seat 31 with the largest diameter can be stably fitted and placed on the first pressure cap 33 through one of the stepped structures, and the other stepped structure can be fitted and placed on the end of the polymer inner tube 34 that extends out of the first pressure cap 33. In this way, the connecting seat 31, together with the water nozzle 2, can be stably installed in the first body assembly 3 and is easy to remove.

[0044] Since the first pressure cap 33 is a component that directly faces the upper surface of the mounting platform, a washer can be provided on the bottom surface of the first pressure cap 33. The first locking sleeve 37 of the first body assembly 3 is used to fit onto the first metal sleeve 35 from the lower surface of the mounting platform and lock the first body assembly 3 to the mounting platform. For this purpose, the first locking sleeve 37 can be provided with internal threads so as to engage with the first metal sleeve 35. A first pad 36 can also be provided between the first locking sleeve 37 and the lower surface of the mounting platform. The first pad 36 is fitted over the first metal sleeve 35 and is pressed against the lower surface of the mounting platform and the first locking sleeve 37. Of course, in order to increase the preload, a washer can also be provided on the first locking sleeve 37, which is pressed against the first locking sleeve 37 and the first pad 36.

[0045] The second end of the polymer inner tube 34, opposite the first end, is used to connect to the first pipe fitting 38. For example... Figure 5As shown, the first pipe connector 38 includes a first outlet pipe section 382 and two first inlet pipe sections 381 located on opposite sides of the first outlet pipe section 382 and connected to it. The first outlet pipe section 382 is in fluid communication with the inner hole of the polymer inner tube 34, while the two first inlet pipe sections 381 are respectively in fluid communication with the two second body assemblies 5 for hot and cold water. Thus, hot and cold water can enter the first outlet pipe section 382 through the two first inlet pipe sections 381 respectively, and further flow to the faucet 2 through the polymer inner tube 34.

[0046] The first pipe connector 38 is detachably connected to the polymer inner tube 34 using a retaining ring 6. The retaining ring 6 can rotate relative to the first pipe connector 38 to facilitate installation into the polymer inner tube 34 without causing folding or twisting between the pipes. Furthermore, the retaining ring 6 is easy to operate under the mounting platform without requiring pre-reserved installation space on the mounting platform, allowing for simple and quick connection between pipes.

[0047] like Figure 5 Of Figure 7 As shown, for the installation of the retaining ring 6, a circumferentially extending annular groove is formed on the outer periphery of the first pipe fitting 38, and first locking slots 383 are formed on opposite sides of the annular groove. The retaining ring 6 is semi-annular in shape, with an outwardly flipped hook 61 formed at one end and an outwardly bent fastening portion 63 formed at the other end. The hook 61 can be inserted into one of the first locking slots 383 and hooked onto the first outer wall section 383 of the first pipe fitting 38. With the aid of the hook 61, the retaining ring 6 can rotate about its connection with the first pipe fitting 38. After the polymer inner tube 34 is inserted into the first outlet pipe section 381 of the first pipe fitting 38, the retaining ring 6 is rotated to press the fastening portion 63 into the other first locking slot 383, so that the retaining ring 6 can clamp or lock the polymer inner tube 34. To facilitate smoother pressing into the fastening portion 63, a portion of the inner circumferential surface of the adjacent fastening portion 63 of the retaining ring 6 is formed as an arc surface, which can be adapted to the outer circumferential arc of the polymer inner tube 34. At this time, at least a portion of the retaining ring 6 is embedded in the circumferential groove of the first pipe joint 38, so it does not protrude significantly outward relative to the first pipe joint 38, resulting in a more integrated visual effect and without taking up extra space.

[0048] The retaining ring 6 may have a thickened portion 62 formed on its inner circumference near the hook portion 61 to facilitate a tight engagement with the polymer inner tube 34. Additionally, the outer circumference of the retaining ring 6 may have a protrusion 65, which may be positioned closer to the fastening portion 63 and extend obliquely away from the hook portion 61. When the retaining ring 6 is installed to the first pipe fitting 38 and the polymer inner tube 34 is clamped, the protrusion 65 may rest against the first outer wall section 384 of the first pipe fitting 38. The protrusion 65 facilitates manual operation by the operator, such as pushing the protrusion 65 to press the fastening portion 63 into the first latch 383, or flicking the protrusion 65 to pull the fastening portion 63 out of the first latch 383.

[0049] Figures 8 to 10 The configuration of the second body assembly 5 on one side and its connection to the handle 4 are shown. As shown, in the second body assembly 5, a polymer core tube 54 is inserted into a polymer outer tube 55 to form a composite flow channel. The inner hole of the polymer core tube 54 forms an inner fluid channel, while the gap between the polymer core tube 54 and the polymer outer tube 55 forms an outer fluid channel. The polymer core tube 54 and the polymer outer tube 55 can be, for example, plastic tubing. To facilitate the assembly of the polymer core tube 54 and the polymer outer tube 55, a tongue-and-groove fitting structure can be provided between the polymer core tube 54 and the polymer outer tube 55. In the illustrated embodiment, the polymer core tube 54 has an axially extending second protrusion 541 formed on its outer periphery, while the polymer outer tube 55 has a second slot 552 formed on its inner surface. By inserting the second protrusion 541 into the second slot 552, the polymer core tube 54 and the polymer outer tube 55 can be securely connected together.

[0050] The second metal sleeve 56 is fitted onto the polymer outer tube 55 and fits tightly against the outer surface of the polymer outer tube 55. Similarly, to facilitate the assembly of the second metal sleeve 56 and the polymer outer tube 55, a tongue-and-groove fitting structure can be provided between the second metal sleeve 56 and the polymer outer tube 55. In the illustrated embodiment, the polymer outer tube 55 has an axially extending third protrusion 551 on its outer surface, while the second metal sleeve 56 forms a third slot 561. By inserting the third protrusion 551 into the third slot 561, the polymer outer tube 55 and the second metal sleeve 56 can be securely connected together.

[0051] The valve core 52 is located at the first end of the polymer core tube 54, and the inlet of the valve core 52 is connected to the internal fluid channel formed by the inner hole of the polymer core tube 54, while the outlet of the valve core 52 is connected to the external fluid channel between the polymer core tube 54 and the polymer outer tube 55. To install the valve core 52, a top cover 51 with internal threads can be provided, and an external thread is formed at the first end of the polymer core tube 54. The radial protrusion of the valve core 52 is placed on the end face of the polymer core tube 54, and the top cover 51 is fitted onto the polymer core tube 54 from the first end, so that the radially inwardly extending flange of the top cover 51 presses against the radial protrusion of the valve core 52. The top cover 51 is then locked onto the polymer core tube 43 via a threaded connection. In this way, the valve core 52 and the polymer core tube 54 are directly connected through the top cover 51 and assembled together with the polymer outer tube 55, realizing an adjustable inlet and outlet water circuit and optimizing the water circuit structure.

[0052] Similarly, to facilitate the assembly of the valve core 52 and the polymer core tube 54, a mating insertion structure can be provided between the valve core 52 and the polymer core tube 54. In the illustrated embodiment, the valve core 52 has an axially extending fourth protrusion 521 on its outer surface, while the polymer core tube 54 forms a fourth slot 542. By inserting the fourth protrusion 521 into the fourth slot 542, the valve core 52 and the polymer core tube 54 can be securely connected together.

[0053] The polymer core tube 54 and the polymer outer tube 55 can be connected by a second cap 53. In the illustrated embodiment, the second cap 53 has internal threads, while the second metal sleeve 56 has external threads. When inserting the polymer core tube 43 into the polymer outer tube 55, the radial flange of the polymer core tube 43 can be placed on the end face of the polymer outer tube 55, and the radial flange of the polymer outer tube 55 can be placed on the end face of the second metal sleeve 56. Then, the second cap 53 is screwed onto the second metal sleeve 56, at which point the radially inwardly extending flange of the second cap 53 presses against the radial flange of the polymer core tube 43. The handle 4 can be installed to the valve core 52 via the connector 41 to control the opening or closing degree of the valve core 52.

[0054] Similar to the first pressure cap 33, the second pressure cap 53 is a component that directly faces the upper surface of the mounting platform; therefore, a washer 531 can be provided on the bottom surface of the second pressure cap 53. The second locking sleeve 58 of the second body assembly 3 is used to fit onto the second metal sleeve 56 from the lower surface of the mounting platform and lock the second body assembly 3 to the mounting platform. For this purpose, the second locking sleeve 58 can have internal threads to engage with the second metal sleeve 56. A second pad 57 can also be provided between the second locking sleeve 58 and the lower surface of the mounting platform. This second pad 57 fits over the second metal sleeve 56 and is pressed against the lower surface of the mounting platform and the second locking sleeve 58. Of course, to increase the preload, a washer can also be provided on the second locking sleeve 58, pressing against the second locking sleeve 58 and the second pad 57.

[0055] The second end of the polymer outer tube 55, opposite the first end, is used to connect to the second pipe fitting 59. For example... Figure 11As shown, the second pipe connector 59 includes a second inlet pipe section 591 and a second outlet pipe section 592 that are connected to each other. The second inlet pipe section 591 is connected to the internal fluid channel formed by the inner hole of the polymer core tube 54, while the second outlet pipe section 592 is connected to the external fluid channel formed between the polymer core tube 54 and the polymer outer tube 55, and the second outlet pipe section 592 is connected to the first inlet pipe section 381 of the first body assembly 3. Thus, the flow path of the faucet device 1 is formed. Water (cold or hot water) flows from the second inlet pipe section 591 of the second pipe connector 59 into the internal fluid channel of the second body assembly 5, and flows into the inner cavity of the valve core 52 through the inlet of the valve core 52. After the valve core 52 is opened, the fluid flows into the external fluid channel of the second body assembly 5 through the outlet of the valve core 52, and enters the first inlet pipe section 381 of the first pipe connector 38 through the second outlet pipe section 592 of the second pipe connector 59. Afterwards, the fluid enters the fluid channel of the first body assembly 3 through the first outlet pipe section 382 of the first pipe joint 38, until it finally flows out through the water nozzle 2.

[0056] To connect the first pipe connector 38 and the second pipe connector 59, external threads can be provided on the first inlet pipe section 381 of the first pipe connector 38 and the second outlet pipe section 592 of the second pipe connector 59, and internal threads can be formed at both ends of the hose 7. By means of threaded engagement, the hose 7 is fluidly connected between the first inlet pipe section 381 of the first pipe connector 38 and the second outlet pipe section 592 of the second pipe connector 59.

[0057] Similar to the connection between the first pipe connector 38 and the polymer inner tube 34, the second pipe connector 59 is also detachably connected to the polymer outer tube 55 via a retaining ring 6. Figures 11 to 13 As shown, the retaining ring 6 can rotate relative to the second pipe fitting 59 to facilitate installation onto the polymer outer tube 55 without causing folding or twisting between the pipes. Furthermore, the retaining ring 6 is easy to operate under the mounting table, eliminating the need for pre-reserved installation space on the mounting table, and allowing for simple and quick connection between pipes.

[0058] To accommodate the retaining ring 6, a circumferential groove is formed on the outer periphery of the second pipe fitting 59, and second locking slots 593 are formed on opposite sides of the groove. The hook portion 61 of the retaining ring 6 can be inserted into one of the second locking slots 593 and hooked onto the second outer wall section 594 of the second pipe fitting 59. The hook portion 61 allows the retaining ring 6 to rotate about its connection point with the second pipe fitting 59. After the polymer outer tube 55 is inserted into the second inlet pipe section 591 of the second pipe fitting 59, rotating the retaining ring 6 presses the fastening portion 63 into the other second locking slot 593, allowing the retaining ring 6 to clamp or lock the polymer outer tube 55. To facilitate smoother pressing of the fastening portion 63, a portion of the inner circumferential surface of the adjacent fastening portion 63 of the retaining ring 6 is formed as an arc surface, which can be adapted to the outer circumferential arc of the polymer outer tube 55. At this time, at least a portion of the retaining ring 6 is embedded in the circumferential groove of the second pipe connector 59, so it does not protrude significantly outward relative to the second pipe connector 59, resulting in a more integrated visual effect and without taking up extra space.

[0059] The installation process of the faucet device 1 of this utility model is described below with reference to the accompanying drawings.

[0060] First, the polymer inner tube 34 is inserted into the first metal sleeve 35 and locked in place with the first pressure cap 33, thus forming... Figure 14 The first body group 3 is shown.

[0061] Insert the polymer outer tube 55 into the second metal sleeve 56, and then insert the polymer core tube 54 into the polymer outer tube 55. Next, insert the valve core 52 into the polymer core tube 54. Secure with the top cover 51 and the second pressure cap 53 to complete the assembly. Figure 15 The second body group 5 is shown.

[0062] like Figure 16A As shown, a first body assembly 3 is centered, and two second body assemblies 5 are placed on opposite sides of the first body assembly 3, inserted into the preset mounting holes from above the mounting platform 8. Then, according to... Figure 16B As shown, from below the mounting platform 8, the first body assembly 3 and the second body assembly 5 are fastened to the mounting platform 8 by the first locking sleeve 37 and the second locking sleeve 58, respectively.

[0063] like Figure 16C As shown, the first pipe connector 38 and the second pipe connector 59 are connected by a flexible hose 7. At this time, the retaining ring 6 is hooked onto the corresponding pipe connector by the hook part 61 and can rotate around the connection.

[0064] like Figure 16D As shown, the first pipe fitting 38 and the second pipe fitting 59 are respectively fitted onto the corresponding polymer inner tube 34 or polymer outer tube 55. Then, the retaining ring 6 is rotated to press the fastening part 63 into the corresponding pipe fitting's bayonet, thereby locking the pipe fitting with the corresponding polymer pipe fitting.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0066] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model.
