Abstract
Description
Technical Field
[0001] This application relates to faucet fittings, and more particularly to the water flow structure of faucets. Background Technology
[0002] Horizontally oriented faucets, such as shower column faucets, are typically designed with a single piece of metal cast to form the body. A water temperature regulating valve and an optional regulating valve for the water outlet are then fitted to form the faucet body. After connecting the inlet and outlet water pipes and the shower head, it is ready to use.
[0003] In recent years, a new type of faucet construction has emerged for basin faucets, featuring a unique water-passing structure. This method utilizes a flexible engineering material, such as polymers, to form the core of the faucet, which is then encased in a metal shell to form the faucet body. This approach significantly reduces the amount of expensive metals like copper used, thereby lowering the faucet's price. Furthermore, the water-passing structure, as a separate component, can be replaced entirely, offering convenience and hygiene.
[0004] However, there is currently no good design for the water passage structure that is horizontally set and may have multiple water outlets, such as for shower column faucets. In particular, it is difficult to manufacture a water passage structure that can meet all the functions of a shower column faucet while maintaining a relatively thin overall thickness.

[0029] The faucet water passage structure of this utility model will be described in detail below with reference to the accompanying drawings.
[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 According to one embodiment of the present invention, a faucet water passage structure 13 includes a seat 131. The first end 131A of the seat forms an inner cavity 132. The inner cavity 132 is cylindrical and includes a first water supply chamber 1321 adjacent to the first end, a second water supply chamber 1322 away from the first end 131A relative to the first water supply chamber, and a mixing chamber 1323 away from the first end relative to the second water supply chamber. The first water supply chamber 1321 is connected to a first water supply interface 1331 formed on the side wall 1311 of the seat, and the second water supply chamber 1322 is connected to the second water supply interface 1332 formed on the side wall 1311 of the seat through a first water supply channel 1341.
[0031] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the first water supply channel 1341 includes a second segment 1341B disposed radially close to the transverse axis X of the seat and a first segment 1341A disposed away from the transverse axis X, such that the first water supply channel 1341 bypasses the mixing chamber 1323 and communicates with the second water supply chamber 1322; the second segment 1341B has a channel opening 1311B at the second end 131B.
[0032] The second segment 1341B of the first water supply channel 1341 can be connected to the channel opening 1311B provided at the second end 131B of the seat 131. The channel opening 1311B is, for example, strip-shaped. This arrangement is intended to facilitate the forming of the faucet water passage structure 13, because the second water supply channel 1341 is divided into two segments, and it would be difficult to manufacture if the second segment 1341B were directly closed.
[0033] A second water supply channel 1342 is disposed at a position closer to the transverse axis X than the first water supply channel 1341, for example, at a position coinciding with the transverse axis X. One end of the second water supply channel 1342 is connected to the mixing chamber 1323, and the other end is connected to the water supply opening 1312B located at the second end 131B of the seat. The water supply opening 1312B is, for example, circular.
[0034] The second end 131B is also provided with a first drain channel opening 1313B and a second drain channel opening 1314B, which are, for example, strip-shaped.
[0035] A first water outlet 1361 is provided at a first position on the side wall of the seat body. The first water outlet 1361 is connected to a first drain channel 1351, and the first drain channel 1351 is connected to the opening 1313B of the first drain channel. At a second position on the side wall of the seat body, for example, in the middle, a second water outlet 1362 is provided. The second water outlet 1362 is connected to a second drain channel 1352, and the second drain channel 1352 is connected to the opening 1314B of the second drain channel.
[0036] A second water outlet 1362 can be provided on the side wall of the seat, for example, at a position facing downwards from the middle. The second water outlet 1362 can be in the same axial position as the first water outlet 1361 but in a different circumferential position. The second water outlet 1362 is connected to the second drainage channel opening 1314B located at the second end 131B of the seat through a second drainage channel 1352. The second drainage channel 1352 can extend along the transverse axis X of the seat, and its radial position can be the same as the first water supply channel 1341 and / or the first drainage channel 1351, that is, it is radially equidistant from the transverse axis X.
[0037] In some embodiments, such as Figure 8 , Figure 9 As shown, a third water outlet 1363 can be provided on the side wall of the seat, for example, at a position facing upwards from the middle. The third water outlet 1363 can be in the same axial position as the first water outlet 1361 and the second water outlet 1362, but in a different circumferential position. The third water outlet 1363 is connected to the opening 1313B of the first drainage channel located at the second end 131B of the seat through the first drainage channel 1351. In this way, the forward-facing first water outlet 1361 and the upward-facing third water outlet 1363 share a single channel, thereby reducing the space occupied. The cross-sectional shape of the first drainage channel 1351 can be as follows: Figure 9 The image shows a kidney shape that conforms to the curved surface.
[0038] Therefore, in some embodiments, the first water supply channel 1341, the first drain channel 1351, and the second drain channel 1352 are in the same radial position and are equidistantly arranged on the outer side of the circumference of the second water supply channel 1342. Correspondingly, the channel opening 1311B, the first drain channel opening 1313B, and the second drain channel opening 1314B are in the same radial position at the second end and are equidistantly arranged on the outer side of the circumference of the water supply opening 1312B.
[0039] A positioning hole 1315B may also be provided at the second end 131B to engage with the valve core 151 of the switching valve 15, which is used to selectively connect the channel opening 1311B, the water supply opening 1312B, the first drain channel opening 1313B, and the second drain channel opening 1314B, for positioning. A engagement structure 1316B, such as a thread, may also be provided on the outer periphery of the second end 131B to engage with the first pressure cap 152 of the switching valve 15 to position the valve core 151.
[0040] In some embodiments, the first water supply chamber 1321, the second water supply chamber 1322, and the mixing chamber 1323 may be coaxially arranged with the transverse axis X.
[0041] In other embodiments, the first water supply chamber 1321, the second water supply chamber 1322, and the mixing chamber 1323 may be not coaxial with the transverse axis X, that is, they may be distributed at a distance from the transverse axis X.
[0042] A temperature regulating valve 14 is provided in the inner cavity 132 of the seat body. The temperature regulating valve includes a temperature regulating valve core 141 and a valve core shell 142 sleeved on the outside of the temperature regulating valve core 141, as well as a fixing structure for fixing the temperature regulating valve core 141 to the seat body 131. For example, the fixing structure may include a threaded plate 145 fixed to the seat body by screws 143 and a second pressure cap 144 threaded to the inner ring of the threaded plate 145.
[0043] like Figure 8 As shown, the switching valve core 151 is provided with a first inlet 1511, a blind port 1512, a first upper outlet 1513, and a first lower outlet 1514. The first inlet 1511 is connected to the second water supply channel 1342 that connects to the mixing chamber. The blind port 1512 is connected to the first water supply channel 1341 that connects to the second water supply chamber 1322. The first upper outlet 1513 is connected to the first outlet 1361 of the seat. The first lower outlet 1514 is connected to the second drain channel 1352.
[0044] like Figure 10 , Figure 11 As shown, the temperature control valve core shell 142 is a hollow structure, including a first shell portion 1422 that mates with the mixing chamber, and a second shell portion 1423 that mates with the first and second water supply chambers. The first shell portion 1422 has a shell end 1421 for engaging with an end opening in the mixing chamber, and a first connecting hole 1421A connecting the mixing chamber and the interior of the first shell portion. The second shell portion 1423 has a first water inlet slot 1424 positioned to match the first water supply chamber 1321 and a second water inlet slot 1425 positioned to match the second water supply chamber 1322. The temperature control valve core 141 has a valve core end 1411 abutting against the inside of the first shell portion, an adjusting section 1412 engaging inside the first shell portion 1422, and a knob portion 1413 engaging on the adjusting section 1412. The valve core end 1411 has a second connecting hole 1411A for connecting the interior of the adjusting section to the interior of the first housing portion 1422 of the temperature regulating valve core housing 142. The adjusting section includes a first annular groove 1414A aligned with the first water inlet 1424 and a second annular groove 1414B aligned with the second water inlet 1425. The adjusting section 1412 includes a shoulder 1412C and a protrusion 1412D to fix the temperature regulating valve core to the seat 131. The knob portion 1413 protrudes from the seat 131 after installation, allowing it to engage with an external operating handle, etc.
[0045] In the embodiments of this utility model, the faucet water passage structure 13 is formed by injection molding of polyphthalamide (PPA) material.
[0046] like Figure 12 The diagram shown is a schematic representation of a faucet water passage structure according to an embodiment of the present invention, after being enclosed in a housing. It includes a faucet housing 10 and a faucet water passage structure 13, a thermostatic valve core 141, a switching valve core 151, and inlet foot assemblies 11 and 12, as well as a front outlet assembly 17, all disposed within the faucet housing 10. The thermostatic valve core housing 142 is installed within the inner cavity 132 of the seat of the faucet water passage structure 13. The thermostatic valve core 141 is mounted on the thermostatic valve core housing 142, with a portion of the thermostatic valve core housing 142 extending out of the faucet water passage structure 13 and engaging with a first handle 41. The switching valve 151 is installed at the second end 131B of the faucet water passage structure 13 and engages with a second handle 42. The inlet foot assemblies 11 and 12 are mounted on the faucet housing 10 and are connected to a first water supply interface 1331 and a second water supply interface 1332 on the seat 131 of the faucet water passage structure 13. The first outlet 1361, second outlet 1362, and / or third outlet 1363 of the faucet water passage structure 13 can be connected to a water outlet assembly. For example, the forward-facing first outlet 1361 can be connected to the front water outlet assembly 17, which may be, for example, a waterfall water outlet assembly. The second outlet 1362 can face downwards and can be coupled to the first threaded water outlet assembly, thereby connecting to the inlet of the top shower head's water hose. The third outlet 1363 can face upwards and can be coupled to the second threaded water outlet assembly, which can be connected to the water hose of the handheld shower head.
[0047] By adopting the structural design of this utility model, the height of the water passage structure can be reduced to only 31.6mm, making it suitable for faucets with a shell diameter greater than or equal to 35mm, which is thinner than faucets on the market with diameters ranging from 38mm to 40mm. The water passage structure can have up to three outlets: a top outlet, a front outlet, and a bottom outlet, forming different combinations of top-outlet, bottom-outlet, and front-outlet faucets, thus serving as the water passage structure for bottom-outlet, top-outlet, front-outlet, or combined faucets. The provided front outlet can be combined with the faucet shell to create a waterfall effect.
[0048] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
