Description

Technical Field

[0001] This application relates to water supply valve devices, and more particularly to faucets and their components. Background Technology

[0002] To reduce the use of precious metals such as copper in faucet manufacturing and to avoid potential water pollution caused by contamination of the faucet's inner surface during electroplating, an independent water flow structure was designed as a closed path for water intake in the faucet. However, traditional water flow structures are designed for faucets with fixed water outlet pipes and cannot meet the needs of scenarios requiring rotating water outlet pipes. Utility Model Content

[0003] The purpose of this invention is to provide an improved water passage structure that has a rotatable function.

[0004] Therefore, some embodiments of this application provide a rotatable faucet water passage structure, which includes a valve core base and a valve seat outer sleeve; the valve core base is used to cooperate with a valve core; the valve core base includes an upper mating section, an upper sealing section, a water outlet section, a lower sealing section, and a lower mating section arranged axially from top to bottom; a first water inlet hole and a second water inlet hole are arranged axially through the valve core base, the first water inlet hole and the second water inlet hole are connected to two water inlets of the valve core, and are used to supply water to the valve core; the water outlet section is connected to an axially arranged water outlet hole, the water outlet hole is connected to the water outlet of the valve core, and is used to deliver the mixed water provided by the valve core to the water outlet section; the upper sealing section is fitted to the upper section of the valve seat outer sleeve through a first sealing unit, the lower sealing section is fitted to the lower section of the valve seat outer sleeve through a second sealing unit, and a water passage chamber is formed between the middle section of the valve seat outer sleeve and the water outlet section; the valve seat outer sleeve also includes a water supply section extending obliquely upward, the water supply section being connected to the water passage chamber.

[0005] In some embodiments, the valve core base also provides an outlet on a side away from the water supply section, the outlet communicating with the drain hole inside the valve core base; the water passage chamber is configured as a cylindrical region, thereby allowing mixed water from the outlet to flow to the water supply section.

[0006] In some embodiments, the first sealing unit includes an upper axial sealing ring and an upper lateral sealing ring, wherein the upper lateral sealing ring is fitted at a position between the upper sealing section and the upper segment in the lateral direction to rotatably seal the upper sealing section and the upper segment, and the upper axial sealing ring is axially sealed between the radial edge of the upper housing and the upper segment; the second sealing unit includes a lower axial sealing ring and a lower lateral sealing ring, wherein the lower lateral sealing ring is fitted at a position between the lower sealing section and the lower segment in the lateral direction to rotatably seal the lower sealing section and the lower segment, and the lower axial sealing ring is axially sealed between the lower segment and the lower nut.

[0007] In some embodiments, the hardness of the upper axial seal and the lower axial seal is higher than that of the upper lateral seal and the lower lateral seal, so that the up-and-down swaying generated during rotation is prevented by the upper axial seal and the lower axial seal, which are in direct contact with the lower housing.

[0008] In some embodiments, the coefficient of friction of the upper axial sealing ring and the lower axial sealing ring is less than the coefficient of friction of the upper lateral sealing ring and the lower lateral sealing ring.

[0009] In some embodiments, the first sealing unit includes only the upper lateral sealing ring, and the second sealing unit includes only the lower lateral sealing ring.

[0010] In some embodiments, the upper lateral sealing ring and the lower lateral sealing ring have a greater dimension in the height direction than in the radial direction.

[0012] In some embodiments, the lower housing includes a notch, which is configured such that after the lower housing is fitted onto the outside of the valve seat outer sleeve, the water supply section of the valve seat outer sleeve enters the notch, so that rotation of the water supply section causes the lower housing to rotate together. At the same time, the valve core base is also sealed to the upper and lower sections of the valve seat outer sleeve. The proximal end of the water outlet sleeve has the same configuration as the notch of the lower housing, while its distal end has a configuration for accommodating the water outlet nozzle, and the water outlet nozzle sleeve is matched at the distal end.

[0030] Reference Figure 1 , Figure 2 As shown, in one embodiment of this application, the rotatable faucet water passage structure 100 includes a valve core base 6, which can cooperate with a valve core 4. The valve core base 6 includes an upper mating section 61, an upper sealing section 62, a water outlet section 63, a lower sealing section 64, and a lower mating section 65 arranged axially from top to bottom. A first water inlet hole and a second water inlet hole are arranged axially through the valve core base 6. The first water inlet hole and the second water inlet hole are connected to the two water inlets of the valve core 4 for supplying water to the valve core 4. The water outlet section 63 is connected to an axially arranged water outlet hole 631, which is connected to the water outlet of the valve core for delivering the mixed water provided by the valve core to the water outlet section 63. The upper sealing section 62 is mated with the upper section 101 of the valve seat outer sleeve 10 through a first sealing unit, and the lower sealing section 64 is mated with the lower section 103 of the valve seat outer sleeve 10 through a second sealing unit. A water passage chamber 105 is formed between the middle section 102 of the valve seat outer sleeve 10 and the water outlet section 63. The valve seat outer sleeve 10 also includes an upwardly extending water supply section 104, which communicates with the water passage chamber 105. The valve core base 6 also provides a water outlet 632 at a rearward position, i.e., on the side away from the water supply section 104. The water outlet 632 communicates with the drain hole 631 inside the valve core base 6. The water passage chamber 105 is a generally cylindrical area, thereby allowing mixed water from the water outlet 632 to flow to the water supply section 104.

[0031] like Figure 1 As shown, the first sealing unit may include an upper axial sealing ring 71 and an upper lateral sealing ring 81, wherein the upper lateral sealing ring 81 is fitted to the upper sealing section 62 and the upper section 101 in the lateral direction, i.e., the radial direction, to rotatably seal the upper sealing section 62 and the upper section 101, and the upper axial sealing ring 71 is axially sealed between the radial edge of the upper housing 5 and the upper section 101; the second sealing unit may include a lower axial sealing ring 72 and a lower lateral sealing ring 82, wherein the lower lateral sealing ring 82 is fitted to the lower sealing section 64 and the lower section 103 in the lateral direction, i.e., the radial direction, to rotatably seal the lower sealing section 64 and the lower section 103, and the lower axial sealing ring 72 is axially sealed between the lower section 103 and the lower nut 12.

[0032] In some embodiments, the hardness of the upper axial sealing ring 71 and the lower axial sealing ring 72 is higher than that of the upper lateral sealing ring 81 and the lower lateral sealing ring 82. This prevents the up-and-down swaying that occurs during rotation from being prevented by the upper axial sealing ring 71 and the lower axial sealing ring 72, which are in direct contact with the lower housing 9, thereby avoiding the upper lateral sealing ring 81 and the lower lateral sealing ring 82 being compressed and causing damage to the liquid seal.

[0033] In some embodiments, the coefficient of friction of the upper axial sealing ring 71 and the lower axial sealing ring 72 is less than the coefficient of friction of the upper lateral sealing ring 81 and the lower lateral sealing ring 82, so that the user can rotate the water outlet pipe without applying excessive torque.

[0034] In some embodiments, the first sealing unit may include only the upper lateral sealing ring 81, and the second sealing unit may include only the lower lateral sealing ring 82.

[0035] The upper lateral sealing ring 81 and the lower lateral sealing ring 82 have a greater dimension in the height direction than in the radial direction; for example, the dimension in the height direction is more than twice the dimension in the radial direction. This difference in height direction ensures the service life of the upper lateral sealing ring 81 and the lower lateral sealing ring 82.

[0036] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 The valve core base 6 is fixed to the bottom of the upper housing 5 via the upper mating section 61. The valve core 6 is fitted onto the valve core base 6 as described above. The upper nut 3 is fixed to the top of the upper housing 5, thereby fixing the valve core 4, valve core base 6, and upper housing 5 together. A top cover 2 can be added to the outside of the upper nut 3, for example, by snapping it onto the outside of the upper nut 3. An operating handle 1 is fitted onto the upper end of the valve core 6.

[0037] The lower housing 9 is sleeved on the outside of the valve seat outer sleeve 10, and its outer contour can match the upper housing 5. Specifically, the lower housing 9 may include a notch 91. After the lower housing 9 is sleeved on the outside of the valve seat outer sleeve 10, the water supply section 104 of the valve seat outer sleeve 10 enters the notch 91. In this way, the rotation of the water supply section 104 will drive the lower housing 9 to rotate together. At the same time, since the valve core base 6 is also sealed to the upper section 101 and the lower section 103 of the valve seat outer sleeve 10, it can be ensured that the mixed water will not leak during rotation.

[0038] like Figure 7 , Figure 8As shown, the water supply section 104 is connected to the inner outlet pipe 16 via a rear clamp 152, and the inner outlet pipe 16 is connected to the outlet nozzle 17 via a front clamp 151. An outlet pipe sleeve 14 is fitted around the outer side of the water supply section 104 and the inner outlet pipe 16. The outlet pipe sleeve 14 is fastened to the valve seat outer sleeve 10 by a fastening structure, such as screws. The proximal end 141 of the outlet pipe sleeve 14 can have the same configuration as the notch 91 of the lower housing 9, while its distal end 142 can have a configuration to accommodate the outlet nozzle. An outlet nozzle sleeve 13 is also matched to the distal end 142.

[0039] The valve core base 6, valve seat sleeve 10, and water outlet 17 are made of metal, ceramic, or synthetic materials, such as PTFE and nylon. The upper housing 5, lower housing 9, and water outlet sleeve 14 are made of metal or synthetic materials, such as stainless steel or copper. The water outlet pipe 1 can be made of synthetic materials, such as PE (polyethylene) or PEX (cross-linked polyethylene).

[0040] The upper lateral sealing ring 81 and the lower lateral sealing ring 82 can be made of nitrile rubber, and the upper axial sealing ring 71 and the lower axial sealing ring 72 can be made of polytetrafluoroethylene.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
