Technical Field

[0001] This application belongs to the field of faucet technology, specifically relating to a faucet and a water supply device. Background Technology

[0002] Dual-outlet faucets are mainly divided into household split-flow type (one inlet and two outlets for domestic water, connecting multiple devices) and water purification type (purified water and domestic water flow), meeting the needs of different scenarios.

Detailed Implementation

[0018] This section will describe in detail the specific embodiments of this application. Preferred embodiments of this application are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of this application, but they should not be construed as limiting the scope of protection of this application.

[0019] In this application, when directions (up, down, left, right, front, and back) are described, it is only for the purpose of describing the technical solution of this application, and does not indicate or imply that the technical features referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on this application.

[0020] In this application, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the stated number; "above," "below," "within," etc. are understood to include the stated number. In the description of this application, the terms "first" and "second" are used only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0021] In this application, unless otherwise explicitly defined, the terms "setup," "installation," and "connection" should be interpreted broadly. For example, they can refer to direct connection or indirect connection through an intermediate medium; they can refer to fixed connection, detachable connection, or integral molding; they can refer to mechanical connection, electrical connection, or connection capable of mutual communication; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this application based on the specific content of the technical solution.

[0022] See Figure 1 and Figure 2The embodiments of this application provide a faucet, including a cylindrical body 1 and a first water outlet structure 21. The top of the cylindrical body 1 has a first water outlet 11, and the bottom of the cylindrical body 1 has a water inlet 12. The first water outlet 11 and the water inlet 12 of the cylindrical body 1 are connected.

[0023] See Figures 4 to 7 The first water outlet structure 21 includes a first shell 211 and a first inner tube 212. The first shell 211 is rotatably mounted on the top of the cylinder 1, and the first shell 211 has openings that are offset from those of the cylinder 1 in the lateral direction. In other words, when projected in the vertical direction, the openings do not coincide with the cylinder 1.

[0024] The first inner tube 212 is installed inside the first housing 211. The first end of the first inner tube 212 passes through the first water outlet 11 in the vertical direction and is rotatably installed on the cylinder 1, realizing the coaxial installation of the first inner tube 212 and the cylinder 1, and the first inner tube 212 has greater flexibility of rotation. The second end of the first inner tube 212 is provided with a first faucet outlet 2121, which extends out of the opening.

[0025] The inlet 12 is used to connect to the first water pipe 31, which is connected to the first inner pipe 212. The first water pipe 31 is used to supply purified water or domestic water, so that the purified water or domestic water flows through the first inner pipe 212 to the first faucet outlet 2121 to realize the function of water dispensing.

[0026] The faucet in this technical solution uses a first inner tube 212 coaxially mounted to the cylinder 1 in the vertical direction, achieving a rotatable installation between the first inner tube 212 and the cylinder 1; and uses a first housing 211 covering the outside of the cylinder 1, achieving a coaxial installation between the first housing 211 and the cylinder 1. When the first water outlet structure 21, formed by the cooperation of the first inner tube 212 and the first housing 211, rotates, the overall flexibility and stability of the first water outlet structure 21 are significantly improved because both the first housing 211 and the first inner tube 212 are coaxially mounted to the cylinder 1, thus enhancing the user experience.

[0027] It is understood that the first inner tube 212 can be composed of multiple connected pipes or a single pipe integrally formed, without limitation. It is also understood that the first housing 211 and the first inner tube 212 can adopt a figure-7 structure. In other words, the first housing 211 and the first inner tube 212 both have a first structural part extending longitudinally and a second structural part extending laterally. The first faucet outlet 2121 is set in the first structural part of the first inner tube 212 to ensure that the first faucet outlet 2121 can be located in a suitable water outlet position.

[0028] See Figure 6 and Figure 7 In some embodiments, the cylinder 1 is provided with an installation sleeve 4, which includes a sleeve body 41 and a limiting ring 42 disposed on the inner circumference of the sleeve body 41. A rotational guide groove is formed between the sleeve body 41 and the limiting ring 42 in the installation sleeve 4. The first end of the first inner tube 212 extends into the rotational guide groove and abuts against the installation sleeve 4, thereby achieving rotatable installation. The rotational guide groove can guide the rotation of the first inner tube 212. By having the first end of the first inner tube 212 abut against the installation sleeve 4, the bottom of the first inner tube 212 is supported and its lower limit is achieved.

[0029] Further, see also Figure 6 and Figure 7 The inner side of the mounting sleeve 4 is provided with a locking block 43 located above the rotating guide groove. The outer periphery of the first inner tube 212 is provided with a locking groove. The locking block 43 extends into the locking groove to lock onto the first inner tube 212, thereby limiting the mounting sleeve 4 and preventing it from moving up and down during rotation, thus improving the rotational stability of the first water outlet structure 21. It can be understood that the locking groove can be set as a complete ring or multiple spaced arc grooves forming a certain angle. The specific setting can be determined according to the rotation range of the first water outlet structure 21, and is not limited here.

[0030] See Figure 6 and Figure 7 In some embodiments, a first water pipe 31 is installed inside the cylinder 1. A first inner pipe 212 has a stepped structure at its first end. The stepped structure includes a first stepped pipe 213 and a second stepped pipe 214 that are sequentially connected to the first inner pipe 212. The inner diameter of the second stepped pipe 214 is larger than that of the first stepped pipe 213. The first inner pipe 212 extends into a rotating guide groove through the second stepped pipe 214. A snap-fit ​​groove is provided on the outer periphery of the second stepped pipe 214. The top end of the first water pipe 31 passes through the second stepped pipe 214 and is then installed on the first stepped pipe 213, realizing a rotatable installation between the first water pipe 31 and the first inner pipe 212.

[0031] Further, see Figure 6 and Figure 7 A sleeve 5 is attached to the outer periphery of the first water pipe 31. The top of the sleeve 5 extends into the second step pipe 214. A sealing ring 6 is provided between the second step pipe 214 and the first water pipe 31. The sealing ring 6 is located above the sleeve 5 to ensure the sealing between the first water pipe 31 and the first inner pipe 212 and to ensure the normal flow of water.

[0032] Furthermore, see Figure 7 The bottom of the sleeve 5 is provided with a convex edge 51 extending laterally. The bottom of the mounting sleeve 4 abuts against the convex edge 51, thereby limiting the mounting sleeve 4 and further ensuring that the mounting sleeve 4 is stably installed in the cylinder 1, thus improving the stability of the installation of the first water outlet structure 21.

[0033] See Figures 1 to 3 , Figure 6 and Figure 7 In some embodiments, the inlet 12 includes a first bottom opening 121 and a second bottom opening 122, and the cylinder 1 is provided with a first channel and a second channel. The first end of the first channel is connected to the top of the cylinder 1, forming a first outlet 11, and the second end of the first channel is connected to the bottom of the cylinder 1, forming a first bottom opening 121. The first end of the second channel is connected to the side of the cylinder 1, forming a second outlet 13, and the second end of the second channel extends through the bottom of the cylinder 1, forming a second bottom opening 122.

[0034] The first channel is used to install the first water pipe 31, which is either a drinking water pipe or a domestic water pipe. The second channel is used to install the second water pipe 32, which is either a drinking water pipe or a domestic water pipe.

[0035] The first water pipe 31 extends into the first channel through the first bottom opening 121 and connects to the first inner pipe 212, thus turning the water path so that the water in the first water pipe 31 can flow out from the first faucet outlet 2121, realizing the water outlet function above; the second water pipe 32 is installed in the second channel through the second bottom opening 122 and turns the water path through the second outlet 13 to lead to the second faucet outlet 221, realizing the water outlet function below.

[0036] Further, see Figures 2 to 4 , Figure 7 A limiting sleeve 7 is provided on the outer periphery of the cylinder 1. The limiting sleeve 7 is located between the first water outlet 11 and the second water outlet 13. The first water outlet structure 21 is located above the limiting sleeve 7. The cylinder 1 is rotatably installed with a second water outlet structure 22 below the limiting sleeve 7. The second water outlet structure 22 is provided with a second faucet outlet 221 that communicates with the second water outlet 13.

[0037] The first housing 211 and the second water outlet structure 22 are respectively abutted against the upper and lower sides of the limiting sleeve 7 so that the first water outlet structure 21 and the second water outlet structure 22 do not interfere with each other when they rotate.

[0038] Specifically, the bottom of the first water outlet structure 21 abuts against the upper side of the limiting sleeve 7, thus providing support and a lower limit for the first water outlet structure 21; the top of the second water outlet structure 22 abuts against the lower side of the limiting sleeve 7, thus providing an upper limit for the second water outlet structure 22. The first water outlet structure 21 and the second water outlet structure 22 are separated by the limiting sleeve 7. Through the limiting function of the limiting sleeve 7, mutual interference and follow-up phenomena are avoided when the two rotate, effectively ensuring the independence of the rotation function of the different water outlet structures in the dual-outlet faucet.

[0039] Further, see Figure 3 , Figure 4 , Figure 6 and Figure 7 A sleeve 8 is provided above the limiting sleeve 7 on the cylinder 1. A circumferentially extending rotation limiting groove 81 is provided on the outer periphery of the sleeve 8. The sleeve 8 is slidably connected to the first housing 211 through the rotation limiting groove 81. By cooperating with the rotation limiting groove 81 through a guide block 215 located inside the first housing 211, when the user pushes the first water outlet structure 21, the rotation limiting groove 81 guides and limits the rotation of the first water outlet structure 21, thereby restricting the rotation angle of the first water outlet structure 21. It is understood that the arc length of the rotation limiting groove 81 can be adaptively adjusted according to the rotation range of the first water outlet structure 21, and is not limited here.

[0040] The limiting sleeve 7 includes an inner sleeve 71 extending axially and a partition ring 72 disposed outside the inner sleeve 71. The inner sleeve 71 is fitted around the outer periphery of the cylinder 1, and the partition ring 72 extends radially along the cylinder 1. The sleeve seat 8 abuts against the top of the inner sleeve 71 to form a bottom support for the sleeve seat 8, which facilitates the stable installation of the sleeve seat 8 on the outside of the cylinder 1.

[0041] A mounting groove 14 is formed between the sleeve 8 and the spacer ring 72 in the cylinder 1. A drag-reducing element 9 is provided in the mounting groove 14 in the cylinder 1. The top of the drag-reducing element 9 is provided with a rolling element 91. In other words, the rolling elements 91 are spaced circumferentially on the top of the drag-reducing element 9. The first housing 211 extends into the mounting groove 14 through the protrusion structure 216 and abuts against the drag-reducing element 9 and the limiting sleeve 7. The first housing 211 can contact the sleeve 8 through the rolling elements 91 on the top of the drag-reducing element 9. When the first water outlet structure 21 rotates, the friction between the first water outlet structure 21 and the sleeve 8 can be greatly reduced by the action of the rolling elements 91, resulting in better rotation effect.

[0042] It is understandable that the rolling element 91 can be a roller or a ball, and the specific setting can be made according to actual needs, without any restrictions here.

[0043] This application also provides a water supply device, including the aforementioned faucet. The water supply device may also include other components such as water valves and water pumps, which are not limited herein.
