Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, and more specifically, to an anti-tangling double swing arm faucet structure. Background Technology

[0002] Currently, most dual-outlet faucets, such as the one disclosed in Chinese patent CN220770253U, include a faucet body, a regular water outlet for dispensing ordinary water, and a purified water outlet for dispensing purified water. The regular water outlet is installed on the faucet body, and the purified water outlet rotates with the faucet body. In this type of design, the internal water circuit structure is complex, resulting in numerous parts and inconvenient installation. Furthermore, the large number of water-passing parts and their high material requirements lead to higher faucet costs. To address this, some faucets use water pipes to replace the internal water circuit. Specifically, both the purified water outlet and the regular water outlet are connected to the outlet of the control valve via water pipes, simplifying the faucet structure. However, since the purified water outlet and / or the regular water outlet are rotatably connected, the water pipes rotate with them, easily causing the two pipes to become entangled, resulting in poor water flow or even faucet malfunction. Utility Model Content

[0003] This utility model discloses an anti-tangling double swing arm faucet structure, which aims to improve the problem of easy tangling of the internal water pipes in existing double-outlet faucets.

[0004] The present invention adopts the following solution:

[0005] An anti-tangling double-swing arm faucet structure includes a main body and a first swing arm and a second swing arm rotatably disposed on the main body. The first swing arm is located above the second swing arm. A purified water outlet on the first swing arm is connected to a purified water pipe, and a raw water outlet on the second swing arm is connected to a raw water pipe. The inlet end of the purified water pipe is equipped with an adapter. The adapter has a first connecting part and a second connecting part that are connected in communication. The first connecting part is used to connect to the purified water pipe, and the second connecting part is used to connect to a purified water inlet pipe. The first connecting part is concentrically disposed with the main body, and the second connecting part is eccentrically disposed with the main body, so that the purified water inlet pipe is away from the raw water pipe.

[0006] As a further improvement, a groove is provided on the side wall of the first connection part, and the water inlet end of the water purification pipe is axially limited by a snap ring that is locked in the groove.

[0007] As a further improvement, both the purified water pipe and the raw water pipe have vertically arranged inlet and outlet sections. The inlet section is used to connect to the corresponding inlet pipe, and the outlet section extends into the swing arm and is fixed to the swing arm by screws.

[0008] As a further improvement, a connector is provided at the top of the main body, the first swing arm is sleeved on the top of the connector, the second swing arm is sleeved on the bottom or middle of the connector, and the second connecting part of the adapter is fixedly connected to the connector.

[0009] As a further improvement, a groove is provided along the inner wall of the connector, and the purified water inlet pipe passes through the groove and is inserted into the second connector.

[0010] As a further improvement, the top of the connector is provided with a first limiting part, and the first swing arm is provided with a second limiting part. The first limiting part and the second limiting part cooperate to limit the rotation angle of the first swing arm. The side wall of the connector is provided with a limiting groove, and the raw water pipe passes through the limiting groove to limit the rotation angle of the second swing arm.

[0011] As a further improvement, the purified water pipe is positioned to be inserted into the first swing arm from top to bottom, the raw water pipe is positioned to be inserted into the second swing arm from bottom to top, and the limiting groove is positioned to extend upward from the bottom end of the connector.

[0012] As a further improvement, the purified water inlet pipe is integrally formed with the connector.

[0013] As a further improvement, the connector has multiple first mounting holes that extend vertically through it. The second connecting part is located above the connector and has multiple second mounting holes. Multiple third mounting holes are provided along the inner wall of the main body. Each first mounting hole is aligned with the second and third mounting holes and is locked in place by fasteners.

[0014] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0015] 1. This application connects the purified water outlet and the raw water outlet to the purified water pipe and the raw water pipe respectively, simplifying the internal structure of the faucet, reducing the number of parts, and thus facilitating installation. Simultaneously, by setting an adapter at the inlet end of the purified water pipe, and ensuring that the first connecting part of the adapter is concentric with the main body, the rotation center of the purified water pipe is the same as the first swing arm, preventing the purified water pipe from tangling. Furthermore, the second connecting part is eccentrically positioned with the main body, allowing the purified water inlet pipe to avoid the raw water pipe, resulting in a more compact structure. In addition, the purified water inlet pipe is inserted into the second connecting part and will not rotate with the purified water pipe, further preventing pipe tangling. This ensures that when the first or second swing arm is turned, the water pipe rotating synchronously with the swing arm will not tangle with the other water pipe due to changes in the direction or angle of rotation, ensuring smooth water flow.

[0016] 2. A groove is provided along the inner wall of the connector. The water inlet pipe passes through the groove and is inserted into the second connector. This facilitates the alignment of the water inlet pipe with the second connector and prevents the water inlet pipe from swinging, further preventing the pipe from getting tangled or twisted.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] The terms “top,” “bottom,” “upper,” “lower,” “left,” “right,” “front,” “back,” and similar expressions used in this document are for illustrative purposes only. The terms “first,” “second,” etc., are only used to distinguish different objects and should not be construed as indicating or implying relative importance or the quantity, specific order, or primary or secondary relationship of the indicated technical features. The term “several” means one or more, and “multiple” means two or more, unless otherwise explicitly specified. Example

[0036] Combination Figures 1 to 12This embodiment provides an anti-tangling double-swing arm faucet structure, including a main body 1 and a first swing arm 2 and a second swing arm 3 rotatably configured on the main body 1. The first swing arm 2 is located above the second swing arm 3. The purified water outlet 21 on the first swing arm 2 is connected to the purified water pipe 22, and the raw water outlet 31 on the second swing arm 3 is connected to the raw water pipe 32. The inlet end of the purified water pipe 22 is equipped with an adapter 25. The adapter 25 has a first connecting part 251 and a second connecting part 252 connected in communication. The first connecting part 251 is used to connect to the purified water pipe 22, and the second connecting part 252 is used to connect to the purified water inlet pipe 26. The first connecting part 251 is concentrically arranged with the main body 1, and the second connecting part 252 is eccentrically arranged with the main body 1 so that the purified water inlet pipe 26 is away from the raw water pipe 32.

[0037] For example, the purified water pipe 22 is inserted into the first connecting part 251, and the purified water inlet pipe 26 is inserted into the second connecting part 252. Purified water flows from the purified water inlet pipe 26 into the second connecting part 252, and then flows through the water passage communicating with the first connecting part 251 to the purified water pipe 22, finally flowing out from the purified water outlet 21. The first connecting part 251 is concentrically arranged with the main body 1, ensuring that the rotation center of the purified water pipe 22 is the same as that of the first swing arm 2, preventing the purified water pipe 22 from tangling. Simultaneously, the second connecting part 252 is eccentrically arranged with the main body 1, allowing the purified water inlet pipe 26 to avoid the raw water pipe 32, resulting in a more compact structure. Furthermore, the purified water inlet pipe 26, inserted into the second connecting part 252, does not rotate with the purified water pipe 22, further preventing the problem of pipe tangling. This ensures that when the first swing arm 2 or the second swing arm 3 is moved, the water pipe that rotates synchronously with the swing arm will not get tangled with the other water pipe due to changes in the direction or angle of rotation, thus ensuring smooth water flow.

[0038] It should be noted that in this embodiment, the purified water is water filtered by a filter. The purified water pipe 22 is connected to the outlet of the purified water valve, and the purified water valve controls the flow of water in the purified water pipe 22. The raw water is municipal tap water, and the raw water pipe 32 is connected to the outlet of the raw water valve, and the raw water valve controls the flow of water in the raw water pipe 32. The purified water valve and the raw water valve can be solenoid valves or ceramic valves, and are not limited to these. The control of purified water and raw water can also be integrated into a single valve core, without specific limitations. Connecting the purified water outlet 21 and the raw water outlet 31 to the purified water pipe 22 and the raw water pipe 32 respectively simplifies the internal structure of the faucet, reduces the number of parts, and facilitates installation.

[0039] In a preferred embodiment, refer to Figures 14 to 17In one embodiment, a slot 254 is provided on the side wall of the first connecting portion 251, and the water inlet end of the purified water pipe 22 is axially limited by a retaining spring 27 that is locked in the slot 254. For example, two slots 254 are symmetrically provided on the first connecting portion 251, and a corresponding engaging portion 271 is provided on the retaining spring 27. Since the retaining spring 27 has an opening, the retaining spring 27 is pressed during installation to move the engaging portion 271 inward. After the retaining spring 27 is released, the engaging portion 271 can be inserted into the slot 254 under the action of elasticity to ensure that the water inlet end of the purified water pipe 26 is axially limited, and to avoid the problem of the purified water pipe 26 coming off due to excessive water pressure.

[0040] In another embodiment, the first swing arm 2 and the second swing arm 3 are arranged vertically parallel to each other and perpendicular to the axis of the main body 1, so as to make the appearance of the faucet simpler and further ensure the height of the faucet. Users can manually adjust the angle of the water outlet by moving the corresponding swing arm according to their needs, which can create different faucet shapes, making the faucet more versatile and adaptable to different installation spaces or decoration styles, thus enhancing the faucet's market competitiveness. Furthermore, the rotation radius of the purified water outlet 21 is greater than that of the second swing arm 3. That is, no matter where the first swing arm 2 and the second swing arm 3 are, the water flowing from the purified water outlet 21 will not splash onto the second swing arm 33, preventing water contamination and splashing, and ensuring a good user experience. In addition, the first swing arm 2 is set higher than the second swing arm 3 so that the purified water outlet 21 is higher than the raw water outlet 31, preventing the purified water outlet 21 from being sprayed by raw water or splashed by sewage.

[0041] Based on the above embodiments, in an optional embodiment of this utility model, a connector 11 is disposed on the top of the main body 1, a first swing arm 2 is sleeved on the top of the connector 11, a second swing arm 3 is sleeved on the bottom or middle of the connector 11, and the second connecting part 252 of the adapter 25 is fixedly connected to the connector 11. For example, the connector 11 has a plurality of vertically penetrating first mounting holes 114, the second connecting part 252 is located above the connector 11 and has a plurality of second mounting holes 253, and a plurality of third mounting holes 12 are provided along the inner wall of the main body 1. Each first mounting hole 114 is aligned with the second mounting hole 253 and the third mounting hole 12 and is locked by a fastener 4. The fastener 4 is preferably a long screw, which is inserted from top to bottom to fix the adapter 25 and the connector 11 to the main body 1, so that the first swing arm 2 and the second swing arm 3 can rotate around the center of the main body 1.

[0042] Furthermore, a groove 113 is provided along the inner wall of the connector 11. The purified water inlet pipe 26 passes through the groove 113 and is inserted into the second connecting part 252. This facilitates the alignment of the purified water inlet pipe 26 with the second connecting part 252 and prevents the purified water inlet pipe 26 from swinging, further preventing the pipe from tangling or twisting. (Refer to...) Figure 13In other embodiments, the water inlet pipe 13 and the connector 11 can be integrally formed to reduce assembly and reduce costs.

[0043] In a preferred embodiment, the top of the connector 11 is provided with a first limiting part 23, and the first swing arm 2 is provided with a second limiting part 115. The first limiting part 23 and the second limiting part 115 cooperate to limit the rotation angle of the first swing arm 2. The side wall of the connector 11 is provided with a limiting groove 111, and the raw water pipe 32 passes through the limiting groove 111 to limit the rotation angle of the second swing arm 3. Both swing arms rotate within the set angle range, which can also prevent the water pipe from getting tangled. Specifically, the inner wall of the first swing arm 2 is provided with a first limiting part 23, and the second limiting part 115 is an arc shape that protrudes along the top surface of the connector 11. The first limiting part 23 is located in the position where there is no second limiting part 115. When the first swing arm 2 rotates, the first limiting part 23 and the second limiting part 115 abut against each other to limit the rotation angle of the first swing arm 2. Preferably, a first locking portion 24 is provided along the inner wall of the first swing arm 2, and a second locking portion 116 is provided on the connecting member 11. The first locking portion 24 and the second locking portion 116 engage to limit the first swing arm 2 axially. The two locking portions can be a snap-fit ​​structure, and there is no specific limitation.

[0044] It should be mentioned that, in this embodiment, the limiting groove 111 not only limits the angle of the swing arm but also reduces the structural space, thereby decreasing the vertical distance between the second swing arm 3 and the first swing arm 2, thus ensuring the overall size of the faucet. Furthermore, the connecting piece 11 enables a rotatable connection between the two swing arms and the main body 1, allowing the water outlet angles of the purified water outlet 21 and the raw water outlet 31 to be adjusted independently, resulting in a simple structure.

[0045] In one embodiment, both the purified water pipe 22 and the raw water pipe 32 have vertically arranged inlet and outlet sections. The inlet section is used to connect to the corresponding inlet pipe, and the outlet section extends into the swing arm and is fixed to the swing arm by screws to facilitate the installation and removal of the water pipes. The vertical arrangement of the inlet and outlet sections ensures smooth rotation and reduces rotational resistance. Furthermore, the purified water pipe 22 is arranged to be inserted into the first swing arm 2 from top to bottom, and the raw water pipe 32 is arranged to be inserted into the second swing arm 3 from bottom to top. The limiting groove 111 is arranged to extend upward from the bottom end of the connector 11. This facilitates the installation of the raw water pipe 32. For example, the first swing arm 2 includes a top cover. During installation, the purified water pipe 22 is first locked to the first swing arm 2, and then the top cover is pressed in. The connection structure between the top cover and the first swing arm 2 can be a snap-fit ​​structure. Similarly, the second swing arm 3 includes a lower cover. During installation, the raw water pipe 32 is first locked to the second swing arm 3, and then the lower cover is pressed in. It should be noted that the width of the limiting groove 111 determines the swing angle of the second swing arm 3. In one embodiment, the width of the limiting groove 111 can also be set to be close to the outer diameter of the raw water pipe 32, so that the raw water pipe 32 is fixed in the limiting groove 111, corresponding to the second swing arm 3.

[0046] In other embodiments, the connector 11 is provided with wear-resistant pads 117 for engaging with the first swing arm 2 and the second swing arm 3. Specifically, two layers of wear-resistant pads 117 are provided between the bottom end of the first swing arm 2 and the second swing arm 3, and two layers of wear-resistant pads 117 are also provided between the second swing arm 3 and the main body 1. The wear-resistant pads 117 are arranged in a ring shape and fitted around the outside of the connector 11, thereby reducing wear on the swing arms during rotation and ensuring the lifespan of the faucet. Preferably, the wear-resistant pads 117 are made of POM and are designed to be concealed by the outer surface to ensure the aesthetics of the faucet.

[0047] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
