Description

Technical Field

[0001] This invention relates to the technical field of faucet structures, and in particular to a double-rotating arm faucet. Background Technology

[0002] In today's kitchen and bathroom industry, mainstream faucet designs often have functional limitations. Conventional faucet designs mostly have only a single water outlet, which can only complete basic drainage operations and cannot meet more diverse usage needs. While some faucet products with relatively complex designs may be equipped with two or more fixed water outlets, their core function, from a control mechanism perspective, still primarily focuses on adjusting the water flow rate. Users can only adjust the water flow size, whether it's a gentle trickle or a relatively rapid, larger flow, by operating the control switch. In addition, there are also faucets on the market that allow water to flow from any position, such as pull-out faucets. These faucets use a flexible hose to adjust the final water flow position; however, the water flow position on the faucet itself remains fixed. In summary, the existing leading enterprise structures have the following significant drawbacks: Firstly, the fixed and rigid location of the water outlet fails to meet users' diverse needs for flexible water use in various scenarios. For example, in a kitchen environment, when multiple tasks need to be performed simultaneously, such as filling a large pot with water and rinsing vegetables, a single-outlet or fixed multi-outlet faucet cannot provide the convenience of directing water flow from different angles. Secondly, in scenarios where space, installation conditions, or other factors limit the use of pull-out faucets, existing faucet structures struggle to achieve dual-sided water flow, significantly restricting the convenience and efficiency of water use. Therefore, the lack of dual-arm rotatable faucet structures is evident in the current market landscape and technological environment, providing ample room for innovative faucet designs.

[0003] In view of this, the inventor specifically designed a double-rotating-arm faucet, which led to this invention. Summary of the Invention

[0004] To solve the above problems, the technical solution of the present invention is as follows: A double-rotor faucet, comprising: The column contains an independent first water pipe and a second water pipe. The lower fixed joint is threaded to be fixed to the upper axial end of the column, and its periphery forms a first water channel that is connected to the first water pipe and is in the shape of a ring. The lower movable joint is rotatably sleeved on the outer periphery of the lower fixed joint, and its outer periphery has a first water outlet that communicates with the first water channel. The lower rotating arm is sleeved on the outer periphery of the lower movable joint, and has a first water outlet passage connected to the first water outlet. The end of the first water outlet passage forms the lower water outlet. The upper fixed joint is fixedly installed at the upper axial end of the lower fixed joint, and its periphery forms a second water channel that is connected to the second water pipe and is in a ring shape. The upper movable joint is rotatably sleeved on the outer periphery of the upper fixed joint, and its outer periphery has a second water outlet that communicates with the second water channel; The upper rotating arm is sleeved on the outer periphery of the upper movable joint, and has a second water outlet passage connected to the second water outlet. The end of the second water outlet passage forms the upper water outlet. The upper and lower rotating arms are provided with a position sensing component, which is used to cut off the water flow path of the second water pipe when the upper and lower rotating arms are in the same vertical position at the same angle. It also includes a display component, which is fixedly mounted on the upper axial end of the upper fixed joint and has a cable at its lower end. The upper fixed joint, the lower fixed joint and the middle part of the column are hollowed out so that the cable can pass through to the bottom of the column.

[0005] Preferably, the position sensing component is a Hall effect sensor.

[0006] Preferably, it also includes a wire threading connector, which is fixed between the lower fixed connector and the upper fixed connector and has a through-hole in its middle to form a wire threading channel, and the side wall of the wire threading connector is provided with wire threading openings distributed along its surface.

[0007] Preferably, the threading opening is arc-shaped and its corresponding central angle is 120°-180°.

[0008] Preferably, the upper and lower water outlets are equipped with water vapor separation boxes or microbubble aerators.

[0009] Preferably, the lower fixed joint has an annular vent groove located below the first water channel on its outer periphery, the lower movable joint has an vent nozzle communicating with the vent groove on its outer periphery, the lower rotating arm has an vent channel communicating with the vent nozzle, the end of the vent channel forms an vent port, and the column has an vent pipe communicating with the vent groove.

[0010] Preferably, the upper and lower rotating arms are parallel and continuously distributed vertically.

[0011] Preferably, the outer periphery of the upper and lower fixed joints, and on both the upper and lower sides of the first and second water channels, are provided with sealing ring grooves for installing sealing rings.

[0012] The beneficial effects of this invention are as follows: This invention enables water to be discharged between the upper and lower rotating arms through an inner and outer ring water channel formed by the upper fixed joint, the lower fixed joint, the lower movable joint, and the upper movable joint. This allows the upper and lower rotating arms to rotate independently to different positions to discharge water, meeting diverse water needs within the same space and greatly improving the convenience and flexibility of water use.

[0013] Meanwhile, the dual-outlet faucet structure of this invention can effectively compensate for limitations in installation locations, significantly improving the convenience and efficiency of water use and broadening the application range of faucet products.

[0014] Furthermore, by using a position sensing component positioned between the upper and lower rotating arms, this invention can automatically cut off the water path when the two arms overlap, thus avoiding water outflow interference when the upper and lower rotating arms coincide.

[0015] In addition, the design of the cable threading connector greatly facilitates the wiring layout. A cable threading port with a certain angle range is opened on the lower rotating arm where the cable needs to be laid, so as to coordinate with the rotation of the lower rotating arm to make stable wiring and stably realize the overlapping monitoring between the upper and lower rotating arms.

[0016] In addition, installing water vapor separation boxes or microbubble aerators at the upper and lower water outlets can, on the one hand, allow the water flow to mix fully with the air, forming a water flow rich in microbubbles, making the water flow softer, reducing water splashing, and improving the user experience; on the other hand, the optimized water flow has a more beautiful appearance, enhancing the product's perceived quality.

[0017] In addition, the outer periphery of the upper and lower fixed joints are provided with sealing ring grooves for installing sealing rings on both the upper and lower sides of the first and second water channels. By installing sealing rings, water leakage at the water channel connection can be effectively prevented, ensuring the sealing and stability of the entire faucet structure, improving product quality, and reducing maintenance costs and inconvenience caused by water leakage.

[0018] In particular, the vent groove on the outer periphery of the lower fixed connector, together with the vent nozzle on the outer periphery of the lower movable connector, the vent channel in the lower rotating arm, and the vent pipe in the column, can promptly expel air from the water pipe, effectively preventing air resistance, ensuring stable and smooth water flow, extending the faucet's service life, and improving product performance.

[0022] To make the technical problems, solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0023] Please see Figures 1 to 5 This is a preferred embodiment of the present invention, a double-rotating arm faucet, comprising a column 100, a lower fixed connector 200, a lower movable connector 300, a lower rotating arm 400, an upper fixed connector 500, an upper movable connector 600, and an upper rotating arm 700, as detailed below: like Figure 1 , 2As shown in Figure 3, the column 100 is equipped with an independent first water pipe 110 and a second water pipe 120.

[0024] In this embodiment, the column 100 is a hollow cylindrical shape with openings at both the top and bottom and forming internal threads for connection (not shown in the figure). The lower end of the column 100 is threadedly connected to a threaded tube 130 for installation. The upper end of the threaded tube 130 is provided with an upper thread 131 that mates with the internal thread of the column 100, and the lower end is provided with a lower thread 132 with an inner diameter smaller than the upper thread 131. The hollow interior of the threaded tube 130 is through, and the lower thread 132 at the lower end of the threaded tube 130 is also threadedly connected to a locking nut 133. Thus, when the column 100 is installed on the corresponding platform, the lower thread 132 of the threaded tube 130 is inserted through the mounting hole on the platform, and then the corresponding locking nut 133 is tightened at the lower end of the mounting hole, thereby fixing the column 100 on the corresponding platform.

[0025] In this embodiment, the first water pipe 110 and the second water pipe 120 are both PE hoses and are connected and extended through a 2-point PE pipe joint (not shown in the figure). The first water pipe 110 and the second water pipe 120 are inserted into the hollow part of the threaded pipe 130 into the hollow part of the column 100.

[0026] like Figure 2 , 3 As shown, the lower fixed joint 200 is located at the upper axial end of the column 100, and a first water channel 231 is formed around it, which is connected to the first water pipe 110 and is in an annular shape.

[0027] like Figure 3 , 4 As shown in Figure 5, in this embodiment, the lower fixed joint 200 is cylindrical in shape, including a first connecting thread 210 at the lower end and an exhaust section 220 and a water outlet section 230 integrally arranged along the axial direction and sequentially disposed at the upper end of the first connecting thread 210. The first connecting thread 210 is used to thread-lock with the internal thread at the upper end of the column 100, thereby locking the lower fixed joint 200 to the upper end of the column 100, serving as the rotation basis for the lower rotating arm 400. The lower fixed joint 200 is axially A first conduit cavity 240 is formed through which the pipeline passes. The first water channel 231 is a closed annular groove structure formed by indentation along the periphery of the outlet section 230. The outer ring of the first water channel 231 is open and its inner side has a first inlet 232. The bottom of the lower fixed joint 200 is provided with a first connecting pipe 233 that communicates with the first inlet 232. The upper end of the first water pipe 110 is connected to the first connecting pipe 233, thereby realizing the purpose of introducing external water source into the annular first water channel 231.

[0028] like Figure 3 , 4As shown, the lower movable joint 300 is rotatably sleeved on the outer periphery of the lower fixed joint 200, and its outer periphery has a first water outlet 310 that communicates with the first water channel 231.

[0029] In this embodiment, the lower movable connector 300 is cylindrical in shape, and its inner side is provided with a first snap-fit ​​cavity 320 that fits with the exhaust section 220 and the water outlet section 230. The first water outlet 310 is a columnar water outlet structure that is radially distributed along the lower movable connector 300 and extends outward integrally. The inner wall of the first snap-fit ​​cavity 320 and the first water channel 231 enclose and form an annular flow channel. The external water source enters the first water channel 231 through the first water pipe 110 and then flows out through the first water outlet 310. Based on this, a rotatable and adjustable water outlet structure is realized, as follows: like Figure 3 , 4 As shown, the lower rotating arm 400 is sleeved on the outer periphery of the lower movable joint 300, and has a first water outlet passage 410 connected to the first water outlet 310 inside. The end of the first water outlet passage 410 forms a lower water outlet 411.

[0030] Specifically, in this embodiment, the lower rotating arm 400 includes a lower rotating sleeve 420 that cooperates with the lower movable joint 300 and a lower water outlet arm 430 that extends radially and integrally to one side along the lower rotating sleeve 420. The first water outlet passage 410 is connected by a PE hose disposed inside the housing of the lower water outlet arm 430. The lower water outlet 411 is disposed on the lower side of the lower water outlet arm 430 and located at the end away from the column 100. The lower rotating sleeve 420 is fixedly sleeved on the outer periphery of the lower movable joint 300, and the first water outlet 310 extends into the lower water outlet arm 430 accordingly. The PE hose corresponding to the first water outlet passage 410 is sleeved on the first water outlet 310 to achieve communication.

[0031] Thus, through the above structure, external water enters the first water channel 231 from the first water pipe 110, flows into the first water outlet passage 410 inside the lower rotating arm 400 along the first water outlet 310, and finally exits through the lower water outlet 411. During this process, when the lower rotating arm 400 rotates, it drives the lower movable joint 300 to rotate around the outer periphery of the lower fixed joint 200. Even if the position of the first water outlet 310 changes with the rotation of the lower movable joint 300, the water flow can still stably enter the first water outlet 310 at different positions from the annular first water channel 231 during the rotation process, so as to achieve stable water output of the lower rotating arm 400 during multi-angle adjustment.

[0032] The above structure enables the lower rotating arm 400 to rotate and discharge water. The following is a breakdown of the rotating water discharge structure of the upper rotating arm 700: like Figure 3 , 4As shown in Figure 5, the upper fixed joint 500 is fixedly installed at the upper axial end of the lower fixed joint 200, and a second water channel 510 is formed around it, which is connected to the second water pipe 120 and is in an annular shape.

[0033] In this embodiment, the upper fixed joint 500 is generally cylindrical, and the second water channel 510 is a closed annular groove structure formed by indentation along the periphery of the upper fixed joint 500. The outer ring of the second water channel 510 is open and its inner side has a second water inlet 511. The bottom of the upper fixed joint 500 is provided with a second connecting pipe 520 that communicates with the second water inlet 511. The upper end of the second water pipe 120 is connected to the second connecting pipe 520, thereby achieving the purpose of introducing external water source into the annular second water channel 510.

[0034] In addition, in this embodiment, the upper fixed joint 500 is fixedly connected to the upper axial end of the lower fixed joint 200 through another wire connector 800, and remains relatively fixed with the column 100, the lower fixed joint 200 and the wire connector 800, serving as the rotation basis of the upper rotating arm 700.

[0035] like Figure 3 , 4 As shown, the upper movable joint 600 is rotatably sleeved on the outer periphery of the upper fixed joint 500, and its outer periphery has a second water outlet 610 communicating with the second water channel 510.

[0036] Specifically, in this embodiment, the upper movable connector 600 is cylindrical in shape, and its inner side is provided with a second snap-fit ​​cavity 620 that fits with the outer peripheral side of the upper fixed connector 500. The second water outlet 610 is a columnar water outlet structure that is radially distributed along the upper movable connector 600 and extends outward integrally. The inner wall of the second snap-fit ​​cavity 620 and the second water channel 510 enclose and form an annular flow channel. The external water source enters the second water channel 510 along the second water pipe 120 and then flows out along the second water outlet 610. Based on this, a rotatable and adjustable water outlet structure is realized, as follows: like Figure 3 , 4 As shown, the upper rotating arm 700 is sleeved on the outer periphery of the upper movable joint 600, and a second water outlet passage 710 connected to the second water outlet 610 is provided inside it. The end of the second water outlet passage 710 forms an upper water outlet 711.

[0037] Specifically, in this embodiment, the upper rotating arm 700 includes an upper rotating sleeve 720 that cooperates with the upper movable joint 600 and an upper water outlet arm 730 that extends radially and integrally to one side along the upper rotating sleeve 720. The second water outlet passage 710 is connected by a PE hose disposed inside the housing of the upper water outlet arm 730. The upper water outlet 711 is disposed on the lower side of the upper water outlet arm 730 and located at the end away from the column 100. The upper rotating sleeve 720 is fixedly sleeved on the outer periphery of the upper movable joint 600, and the second water outlet 610 extends into the upper water outlet arm 730 accordingly. The PE hose corresponding to the second water outlet passage 710 is sleeved on the second water outlet 610 to achieve communication.

[0038] Thus, through the above structure, external water enters the second water channel 510 from the second water pipe 120, flows into the second water outlet passage 710 inside the upper rotating arm 700 along the second water outlet 610, and finally exits through the upper water outlet 711. During this process, when the upper rotating arm 700 rotates, it drives the upper movable joint 600 to rotate around the outer periphery of the upper fixed joint 500. Even if the second water outlet 610 changes position following the rotation of the upper movable joint 600, the water flow can still stably enter the second water outlet 610 at different positions from the annular second water channel 510 during the rotation process, so as to achieve stable water output of the upper rotating arm 700 during multi-angle adjustment.

[0039] Furthermore, in this embodiment, the upper water outlet arm 730 and the lower water outlet arm 430 have the same extension length, the upper water outlet 711 and the lower water outlet 411 are positioned vertically opposite each other, and there is a gap between the upper water outlet arm 730 and the lower water outlet arm 430 to avoid rotational interference.

[0040] Preferably, in order to achieve rotational sensing between the upper rotating arm 700 and the lower rotating arm 400 and avoid water interference when they overlap, a position sensing component 440 is provided between the upper rotating arm 700 and the lower rotating arm 400, which is used to cut off the water flow path of the second water pipe 120 when the upper rotating arm 700 and the lower rotating arm 400 are in the same vertical position at the same angle.

[0041] Specifically, such as Figure 2 , 3 As shown, the position sensing component 440 is a Hall sensor, which is installed and fixed on the upper side of the lower water outlet arm 430. A magnetic component 740 (such as a magnetic buckle) is provided on the lower side of the upper water outlet arm 730 at a position opposite to the Hall sensor. The Hall sensor is connected to the water outlet control part of the second water pipe 120 through a corresponding line. For example, the water outlet control of the second water pipe 120 is controlled by a solenoid valve. When the Hall sensor is activated, the solenoid valve is closed, cutting off the water outlet of the second water pipe 120. Thus, through the above structure, when the upper and lower rotating arms 400 rotate to the same angle and are in a position opposite each other, the water outlet of the upper rotating arm 700 can be cut off, avoiding water outlet interference between the upper and lower rotating arms 700 and the lower rotating arm 400.

[0042] The aforementioned position sensing component 440 involves corresponding circuitry, requiring appropriate wiring to transmit electrical signals to the Hall effect sensor. Therefore, while addressing the rotating water outlet issue, a reasonable design for the wiring arrangement is also necessary. The specific implementation is as follows: Preferred, such as Figure 2 , 4 As shown in Figure 5, it also includes a wire threading connector 800, which is fixed between the lower fixed connector 200 and the upper fixed connector 500 and has a through-hole in its middle to form a wire threading channel 840. The side wall of the wire threading connector 800 is provided with wire threading openings 850 distributed along its surface.

[0043] In this embodiment, the cable threading connector 800 is cylindrical in shape, including a cable threading body 810 located in the middle, a lower connecting part 820 located at the lower axial end of the cable threading body 810, and an upper connecting part 830 located at the upper end of the cable threading body 810. The lower connecting part 820 fits into the upper opening of the lower fixing connector 200 to connect and fix the cable threading body 810 to the upper end of the lower fixing connector 200. The upper connecting part 830 is locked and fixed to the lower end of the upper fixing connector 500, thereby achieving the connection and fixation between the upper fixing connector 500 and the cable threading connector 800. In addition, the cable threading body 810, the upper connecting part 830, and the lower connecting part 820 form the aforementioned cable threading channel 840, which is used for the corresponding cable 910 to pass through along the lower side or for the second water pipe 120 to pass through along the lower side. The cable channel 840 extends upward to the position of the upper fixed connector 500, and the cable opening 850 is opened through the peripheral surface of the cable body 810 to realize the connection between the inner and outer sides of the cable body 810. In this embodiment, the vertical extension of the lower rotating arm 400 can cover the height of the cable connector 800 and the lower fixed connector 200 after assembly, thereby hiding the cable connector 800 and the lower fixed connector 200 in the lower rotating sleeve 420 of the lower rotating arm 400. The space inside the lower water outlet arm 430 is connected to the cable channel 840 through the cable opening 850. The corresponding cable 910 is connected to the space inside the lower water outlet arm 430 and the space inside the main body of the column 100 through the cable opening 850 to realize the wiring of the position sensing component 440.

[0044] Furthermore, the wire-passing opening 850 is arc-shaped and its corresponding central angle is 120°-180°, specifically 180° in this embodiment. Through the large range of the wire-passing opening 850, a wider and more flexible space can be provided for the wiring of the position sensing component 440 during the rotation of the lower rotating arm 400, which facilitates the orderly coordination between the wiring and the rotation of the lower rotating arm 400.

[0045] Preferred, such as Figure 1 , 2The device also includes a display component 900, which is fixedly mounted on the upper axial end of the upper fixed connector 500 and has a cable 910 at its lower end. The upper fixed connector 500, the lower fixed connector 200 and the column 100 are hollowed out in the middle so that the cable 910 can pass through to the bottom of the column 100.

[0046] In this embodiment, the display component 900 is cylindrical and has corresponding circuit components (not shown in the figure) for display and control inside. The cable 910 hangs down along the lower end of the display component 900, and the display component 900 is locked and fixed to the upper axial end of the upper fixed joint 500, forming a relatively fixed connection with the column 100.

[0047] In addition, the upper fixed connector 500 has a through channel running vertically through it. The cable 910 of the display component 900 enters through the channel in the middle of the upper fixed connector 500, continues downward and passes through the wire channel 840 in the middle of the wire connector 800, the first wire cavity 240 in the middle of the lower fixed connector 200 and the hollow part of the column 100 in sequence, and finally exits through the lower opening of the threaded tube 130 for subsequent connection with other circuit control components, such as the solenoid valves of the first water pipe 110 and the second water pipe 120.

[0048] Preferably, the upper outlet 711 and the lower outlet 411 are provided with a water vapor separation box 750 or a microbubble aerator 450. In this embodiment, the water vapor separation box 750 is provided at the upper outlet 711 of the upper rotating arm 700, and the microbubble aerator 450 is provided at the lower outlet 411 of the lower rotating arm 400. Providing the water vapor separation box 750 or the microbubble aerator 450 at the upper outlet 711 and the lower outlet 411 can, on the one hand, allow the water flow to mix fully with the air to form a water flow rich in microbubbles, making the water flow softer, reducing water splashing, and improving the user experience; on the other hand, the optimized water flow has a more beautiful appearance, enhancing the quality of the product.

[0049] Preferably, the lower fixed joint 200 has an annular exhaust groove 221 located below the first waterway 231 on its outer periphery, the lower movable joint 300 has an exhaust nozzle 330 communicating with the exhaust groove 221 on its outer periphery, the lower rotating arm 400 has an exhaust channel 460 communicating with the exhaust nozzle 330, the end of the exhaust channel 460 forms an exhaust port 461, and the column 100 has an exhaust pipe 140 communicating with the exhaust groove 221.

[0050] In this embodiment, the exhaust channel 460 is connected by a PE hose and extends to the lower middle part of the lower water outlet arm 430. A dust plug 462 is also provided at the position of the exhaust port 461. The extension height of the lower rotating sleeve 420 can cover the exhaust section 220 and the water outlet section 230.

[0051] Preferred, such as Figure 4 , 5As shown, sealing ring grooves 250 for installing sealing rings are provided on the outer periphery of the upper fixed joint 500 and the lower fixed joint 200 and on the upper and lower sides of the first water channel 231 and the second water channel 510. A sealing ring is provided in the sealing ring groove 250. Through the sealing ring groove 250 and the sealing ring, the first water channel 231 and the second water channel 510 can be further sealed, and the rotation process of the upper rotating arm 700 and the lower rotating arm 400 can be made smoother.

[0052] The beneficial effects of this invention are as follows: This invention enables water to be discharged between the upper rotating arm 700 and the lower rotating arm 400 through the inner and outer ring water channels formed between the upper fixed joint 200, the upper fixed joint 500, the lower movable joint 300, and the upper movable joint 600. This allows the upper rotating arm 700 and the lower rotating arm 400 to rotate independently to different positions to discharge water, meeting diverse water usage needs within the same space and greatly improving the convenience and flexibility of water use.

[0053] Meanwhile, the dual-outlet faucet structure of this invention can effectively compensate for limitations in installation locations, significantly improving the convenience and efficiency of water use and broadening the application range of faucet products.

[0054] Furthermore, the present invention, through the position sensing component 440 disposed between the upper rotating arm 700 and the lower rotating arm 400, can realize automatic water cut-off when the two overlap, thereby avoiding water outflow interference caused when the upper rotating arm 700 and the lower rotating arm 400 overlap.

[0055] In addition, the design of the cable connector 800 greatly facilitates the wiring layout. A cable opening 850 with a certain angle range is opened on the lower rotating arm 400 where the cable 910 needs to be laid, so as to coordinate with the rotation of the lower rotating arm 400 to make stable wiring and stably realize the overlapping monitoring between the upper rotating arm 700 and the lower rotating arm 400.

[0056] In addition, the outer periphery of the upper fixed connector 500 and the lower fixed connector 200 are provided with sealing ring grooves 250 for installing sealing rings on the upper and lower sides of the first water channel 231 and the second water channel 510. By installing sealing rings, water leakage at the water channel connection can be effectively prevented, ensuring the sealing and stability of the entire faucet structure, improving product quality, and reducing maintenance costs and inconvenience caused by water leakage.

[0057] Specifically, the vent groove 221 on the outer periphery of the lower fixed connector 200, together with the vent nozzle 330 on the outer periphery of the lower movable connector 300, the vent channel 460 in the lower rotating arm 400, and the vent pipe 140 in the column 100, can promptly expel air from the water pipe, effectively avoid air resistance, ensure stable and smooth water flow, extend the service life of the faucet, and improve product performance.

[0058] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
