Description

Technical Field

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

[0002] In the current kitchen and bathroom field, the mainstream faucet structures often have limitations in terms of functions. In the conventional faucet designs, most only have a single water outlet, and can only complete the basic drainage operation, making it difficult to meet more diverse usage requirements.

[0003] In some faucet products with relatively complex designs, although they are equipped with two or more fixed water outlet positions, from the perspective of the control mechanism, their core functions still mainly focus on the adjustment of the water flow rate. Users can only adjust the water flow size by operating the control switch, whether it is a fine trickle or a relatively rapid large water flow.

[0004] In addition, there are also structural forms such as pull-out faucets on the market that can discharge water at any position. Such faucets use a hose to flexibly adjust the final water outlet position. However, the water outlet position on the faucet body remains fixed.

[0005] In summary, the existing various faucet structures mainly have the following significant defects: Firstly, the water outlet position is fixed and rigid, lacking the ability to meet the diverse needs of users for water use flexibility in a rich variety of scenarios. For example, in a kitchen environment, when multiple tasks need to be carried out simultaneously, such as filling a large pot with water and rinsing vegetables, a single water outlet or a fixed multi-water outlet faucet cannot provide the convenience of directional water flow from different angles.

[0006] Secondly, in some scenarios where the space, installation conditions, etc. limit the use of a pull-out structure, the existing faucet structures are difficult to achieve the functional effect of bilateral water discharge, greatly restricting the convenience and efficiency of water use.

[0007] It can be seen that in the existing market pattern and technical environment, the absence of a double-arm rotatable faucet structure is extremely obvious, which also provides a broad development space for innovative faucet designs.

[0008] In view of this, the inventor of the present invention specifically designed a double-rotating-arm faucet, and this case was thus generated. Summary of the Invention

[0013] Preferably, the wire passing openings are arc-shaped and the corresponding central angle is 120°-180°.

[0014] Preferably, a display component is further included. The display component is fixedly provided at the upper end of the upper fixed joint in the axial direction, and a cable is provided at its lower end. The middle parts of the upper fixed joint, the lower fixed joint and the column are hollowed out for the cable to pass through to below the column.

[0015] Preferably, a water vapor separation box or a microbubble bubbler is provided at the upper water outlet and the lower water outlet.

[0016] Preferably, an exhaust groove in a ring shape is provided on the outer peripheral side of the lower fixed joint and below the first water channel. An exhaust nozzle communicating with the exhaust groove is provided on the outer peripheral side of the lower movable joint. An exhaust passage connected to the exhaust nozzle is provided in the lower swing arm. An exhaust port is formed at the end of the exhaust passage. An exhaust pipe communicating with the exhaust groove is provided in the column.

[0017] Preferably, the upper swing arm and the lower swing arm are parallel and continuously distributed up and down.

[0018] Preferably, sealing ring grooves for installing sealing rings are provided on the outer peripheral sides of the upper fixed joint and the lower fixed joint and on the upper and lower sides of the first water channel and the second water channel.

[0019] The beneficial effects of the present invention are as follows: Through the inner and outer ring water channels formed between the upper fixed lower fixed joint, the upper fixed joint, the lower movable joint and the upper movable joint, the present invention realizes the rotating water outlet between the upper rotating arm and the lower rotating arm, so as to realize the independent rotation of the upper rotating arm and the lower rotating arm to different positions for water outlet, meet the diversified water use requirements in the same space, and greatly improve the convenience and flexibility of water use.

[0020] At the same time, for places with limited installation space, the double-outlet faucet structure of the present invention can also effectively make up for it, significantly improve the convenience and efficiency of water use, and broaden the application scope of faucet products.

[0023] In addition, by setting a water vapor separation box or a microbubble foaming device at the upper water outlet and the lower water outlet, on the one hand, the water flow can be fully mixed with air to form a water flow rich in microbubbles, making the water outlet softer, reducing water splash, and improving the use experience; on the other hand, the optimized water flow appearance is more beautiful, enhancing the quality sense of the product.

[0024] In addition, sealing ring grooves for installing sealing rings are provided on the outer peripheral sides of the upper fixed joint and the lower fixed joint on the upper and lower sides of the first water channel and the second water channel.

Detailed implementation manners

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] Please refer to Figures 1 to 5, is a double-rotating arm faucet as the best embodiment of the present invention, including a column 100, a lower fixed joint 200, a lower movable joint 300, a lower rotating arm 400, an upper fixed joint 500, an upper movable joint 600, and an upper rotating arm 700, specifically as follows: As Figure 1 , 2 , as shown in 3, the column 100 is provided with an independent first water pipe 110 and a second water pipe 120.

[0031] In this embodiment, the column 100 is in the shape of a hollow cylinder with both upper and lower ends open and formed with internal threads for connection (not shown in the figure). The lower end of the column 100 is threadedly connected with a threaded pipe 130 for installation. The upper end of the threaded pipe 130 is provided with an upper thread 131 that mates with the internal thread of the column 100, and its lower end is provided with a lower thread 132 with an inner diameter smaller than that of the upper thread 131. The inside of the threaded pipe 130 is hollow and vertically through. The lower thread 132 at the lower end of the threaded pipe 130 is also threadedly connected with a lock nut 133. Thus, when the column 100 is installed on the corresponding tabletop, the lower thread 132 of the threaded pipe 130 is passed through the installation hole along the tabletop, and then the corresponding lock nut 133 is tightened at the lower end of the installation hole, thereby fixing and installing the column 100 on the corresponding tabletop.

[0032] In this embodiment, both the first water pipe 110 and the second water pipe 120 are PE hoses and are connected and extended through a 2-point PE pipe joint (not marked in the figure). The first water pipe 110 and the second water pipe 120 pass through the hollow part of the threaded pipe 130 into the hollow part inside the column 100.

[0033] As Figure 2 , 3 shown, the lower fixed joint 200 is provided at the upper end of the axial direction of the column 100, and a first water channel 231 communicating with the first water pipe 110 and in a ring shape is formed on its peripheral side.

[0034] As Figure 3 , 4, as shown in FIGS. 5, in this embodiment, the lower fixed joint 200 is generally cylindrical, including a first connection thread 210 at the lower end and an exhaust section 220 and a water outlet section 230 integrally arranged axially and successively above the first connection thread 210. The first connection thread 210 is used for thread locking with the internal thread at the upper end of the column 100, so as to lock and fix the lower fixed joint 200 to the upper end of the column 100, serving as the rotation basis of the lower swing arm 400. Among them, a first wire passing cavity 240 for pipelines to pass through is formed axially through the lower fixed joint 200. The first water channel 231 is a closed annular groove-shaped structure recessed inward along the circumferential side of the water outlet section 230. The outer ring of the first water channel 231 is open and its inner side has a first water inlet 232. A first connection pipe 233 communicating with the first water inlet 232 is provided at the bottom of the lower fixed joint 200. The upper end of the first water pipe 110 is connected to the first connection pipe 233, so as to achieve the purpose of introducing external water source into the annular first water channel 231.

[0035] As Figure 3 , 4 shown, the lower movable joint 300 is rotatably sleeved on the outer peripheral side of the lower fixed joint 200, and a first water outlet nozzle 310 communicating with the first water channel 231 is provided on its outer peripheral side.

[0036] In this embodiment, the overall shape of the lower movable joint 300 is cylindrical. A first clamping cavity 320 with a clearance fit with the exhaust section 220 and the water outlet section 230 is provided inside it. The first water outlet nozzle 310 is a columnar water nozzle structure distributed radially along the lower movable joint 300 and extending outward integrally. An annular distributed flow channel is formed by enclosing between the inner wall of the first clamping cavity 320 and the first water channel 231. After the external water source enters the first water channel 231 along the first water pipe 110, it then flows out along the first water outlet nozzle 310. Based on this, a rotatable adjustable water outlet structure is realized, specifically as follows: As Figure 3 , 4 shown, the lower swing arm 400 is sleeved on the outer peripheral side of the lower movable joint 300, and a first water outlet passage 410 connected to the first water outlet nozzle 310 is provided inside it. The end of the first water outlet passage 410 forms a lower water outlet 411.

[0037] Specifically, in this embodiment, the lower swing 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 from the lower rotating sleeve 420 integrally toward one side. The first water outlet passage 410 is formed by connecting a PE hose provided inside the housing of the lower water outlet arm 430. The lower water outlet 411 is provided on the lower side of the lower water outlet arm 430 and at one end away from the column 100. The lower rotating sleeve 420 is fixedly sleeved on the outer peripheral side of the lower movable joint 300, and the first water outlet nozzle 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 nozzle 310 to achieve communication.

[0038] Thus, through the above structure, the external water source enters the first water channel 231 from the first water pipe 110, flows into the first water outlet passage 410 inside the lower swing arm 400 along the first water outlet nozzle 310, and finally discharges water along the lower water outlet 411. During this process, when the lower swing arm 400 rotates, it drives the lower movable joint 300 to rotate integrally around the outer peripheral side of the lower fixed joint 200. Even if the position of the first water outlet nozzle 310 changes following the rotation of the lower movable joint 300, the water flow can still stably enter the first water outlet nozzles 310 at different positions from the annular first water channel 231 during the rotation process, realizing stable water discharge during the multi-angle adjustment of the lower swing arm 400.

[0039] The above structure realizes the rotary water discharge of the lower swing arm 400. Next, the rotary water discharge structure of the upper swing arm 700 will be analyzed: As Figure 3 、 4 、5 shows, the upper fixed joint 500 is fixedly provided at the upper end of the lower fixed joint 200 in the axial direction, and a second water channel 510 that communicates with the second water pipe 120 and is annular is formed on its peripheral side.

[0040] In this embodiment, the upper fixed joint 500 is integrally columnar. The second water channel 510 is a closed annular groove-shaped structure formed by being recessed inward along the peripheral side 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. A second connecting pipe 520 communicating with the second water inlet 511 is provided at the bottom of the upper fixed joint 500. The upper end of the second water pipe 120 is connected to the second connecting pipe 520, so as to achieve the purpose of introducing the external water source into the annular second water channel 510.

[0041] In addition, in this embodiment, the upper fixed joint 500 is fixedly connected to the upper end of the lower fixed joint 200 in the axial direction through another wire passing joint 800, and is relatively fixed with the column 100, the lower fixed joint 200, and the wire passing joint 800, serving as the rotation basis of the upper swing arm 700.

[0042] As Figure 3 、 4As shown, the upper movable joint 600 is rotatably sleeved on the outer peripheral side of the upper fixed joint 500, and a second water outlet nozzle 610 communicating with the second water channel 510 is provided on its outer peripheral side.

[0043] Specifically, in this embodiment, the overall shape of the upper movable joint 600 is cylindrical. A second clamping cavity 620 is provided inside it, which is in clearance fit with the outer peripheral side of the upper fixed joint 500. The second water outlet nozzle 610 is a columnar water nozzle structure distributed radially along the upper movable joint 600 and extending outward integrally. An annularly distributed flow channel is formed by enclosing between the inner wall of the second clamping cavity 620 and the second water channel 510. After the external water source enters the second water channel 510 along the second water pipe 120, it then flows out along the second water outlet nozzle 610. Based on this, a rotatable and adjustable water outlet structure is realized as follows: As Figure 3 、 4 shown, the upper swing arm 700 is sleeved on the outer peripheral side of the upper movable joint 600, and a second water outlet passage 710 connected to the second water outlet nozzle 610 is provided inside it. The end of the second water outlet passage 710 forms an upper water outlet 711.

[0044] Specifically, in this embodiment, the upper swing arm 700 includes an upper rotating sleeve 720 cooperating with the upper movable joint 600 and an upper water outlet arm 730 extending integrally in the radial direction of the upper rotating sleeve 720 toward one side. The second water outlet passage 710 is formed by connecting a PE hose provided inside the housing of the upper water outlet arm 730. The upper water outlet 711 is provided on the lower side of the upper water outlet arm 730 and at the end far from the column 100. The upper rotating sleeve 720 is fixedly sleeved on the outer peripheral side of the upper movable joint 600, and the second water outlet nozzle 610 extends into the upper water outlet arm 730 correspondingly. The PE hose corresponding to the second water outlet passage 710 is sleeved on the second water outlet nozzle 610 to achieve communication.

[0045] Thus, through the above structure, the external water source enters the second water channel 510 from the second water pipe 120, flows into the second water outlet passage 710 inside the upper swing arm 700 along the second water outlet nozzle 610, and finally discharges water along the upper water outlet 711. During this process, when the upper swing arm 700 rotates, it drives the upper movable joint 600 to rotate integrally around the outer peripheral side of the upper fixed joint 500. And even if the position of the second water outlet nozzle 610 changes following the rotation of the upper movable joint 600, the water flow can still stably enter the second water outlet nozzles 610 at different positions from the annular second water channel 510 during the rotation process, realizing stable water discharge during the multi-angle adjustment of the upper swing arm 700.

[0046] In addition, in this embodiment, the extension lengths of the upper water outlet arm 730 and the lower water outlet arm 430 are the same, the positions of the upper water outlet 711 and the lower water outlet 411 are vertically opposite, and there is a gap between the upper water outlet arm 730 and the lower water outlet arm 430 to avoid rotational interference.

[0047] Preferably, in order to achieve rotational induction between the upper swing arm 700 and the lower swing arm 400 and avoid water flow interference when the two overlap, a position sensing component 440 is provided between the upper swing arm 700 and the lower swing arm 400, which is used to cut off the water flow path of the second water pipe 120 when the upper swing arm 700 and the lower swing arm 400 are in the upper and lower positions at the same angle.

[0048] Specifically, as Figure 2 、 3 shown, the position sensing component 440 is a Hall sensing device, which is installed and fixed on the upper side of the lower water outlet arm 430, and a magnetic member 740 (such as a magnetic buckle, etc.) is provided on the lower side of the upper water outlet arm 730 at a position opposite to the Hall sensing device. The Hall sensing device is connected to the water outlet control part of the second water pipe 120 through corresponding wires, such as controlling the water outlet of the second water pipe 120 through a solenoid valve. When the Hall sensing device is activated, the solenoid valve is closed to cut off the water outlet of the second water pipe 120. Thus, through the above structure, when the upper swing arm and the lower swing arm 400 rotate to the positions where the angles are the same and they are opposite to each other up and down, the water outlet of the upper swing arm 700 can be cut off to avoid water flow interference between the upper swing arm 700 and the lower swing arm 400.

[0049] The above-mentioned position sensing component 440 involves corresponding circuit parts and needs to transmit electrical signals to the Hall sensing device through corresponding wiring. Therefore, while solving the problem of rotational water outlet, the layout of the wiring also needs to be reasonably designed. The specific implementation is as follows: Preferably, as Figure 2 、 4 、5 shown, it further includes a wire threading joint 800. The wire threading joint 800 is fixed between the lower fixed joint 200 and the upper fixed joint 500, and a wire threading channel 840 is formed through the middle of it. The side wall of the wire threading joint 800 is provided with wire threading openings 850 distributed along its surface.

[0050] In this embodiment, the wire threading joint 800 is generally cylindrical in shape, including a wire threading main body 810 located in the middle, a lower connecting portion 820 provided at the lower end of the wire threading main body 810 in the axial direction, and an upper connecting portion 830 provided at the upper end of the wire threading main body 810. The lower connecting portion 820 is fitted into the upper side opening of the lower fixed joint 200 for connecting and fixing the wire threading main body 810 to the upper end of the lower fixed joint 200. The upper connecting portion 830 is locked and fixed to the lower end of the upper fixed joint 500 to achieve the connection and fixation between the upper fixed joint 500 and the wire threading joint 800. In addition, a wire threading channel 840 is formed through the wire threading main body 810, the upper connecting portion 830, and the lower connecting portion 820 for allowing the corresponding cable 910 to penetrate from the lower side or for allowing the second water pipe 120 to continue to extend upward along the wire threading channel 840 to the position of the upper fixed joint 500. A wire threading opening 850 is formed through the circumferential surface of the wire threading main body 810 to achieve the communication between the inside and the outside of the wire threading main body 810. In this embodiment, the up and down extension of the lower swing arm 400 can specifically cover the height after the wire threading joint 800 and the lower fixed joint 200 are assembled, so as to hide the wire threading joint 800 and the lower fixed joint 200 in the lower rotating sleeve 420 of the lower swing arm 400. The space inside the lower water outlet arm 430 is communicated with the wire threading channel 840 through the wire threading 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 wire threading opening 850 to realize the wiring of the position sensing component 440.

[0051] Further, the wire threading opening 850 is arc-shaped and its corresponding central angle is 120° - 180°, specifically 180° in this embodiment. Through the large-range wire threading opening 850, during the rotation of the lower swing arm 400, a broader and more flexible moving space can be provided for the wiring of the position sensing component 440, facilitating the orderly cooperation between the wiring and the rotation of the lower swing arm 400.

[0052] Preferably, as Figure 1 、 2 described, a display component 900 is further included. The display component 900 is fixedly provided at the upper end of the upper fixed joint 500 in the axial direction, and a cable 910 is provided at its lower end. The upper fixed joint 500, the lower fixed joint 200, and the middle of the column 100 are hollowed out for the cable 910 to pass through to below the column 100.

[0053] In this embodiment, the display component 900 is cylindrical in shape, and corresponding circuit components for display and control (not shown in the figure) are provided inside it. The cable 910 is vertically provided at the lower end of the display component 900, and the display component 900 is locked and fixed to the upper end of the upper fixed joint 500 in the axial direction to form a relatively fixed connection with the column 100.

[0054] In addition, a vertically penetrating channel is formed inside the upper fixed joint 500. The cable 910 of the display assembly 900 passes through the channel in the middle of the upper fixed joint 500, continues downward and sequentially passes through the threading channel 840 in the middle of the threading joint 800, the first threading cavity 240 in the middle of the lower fixed joint 200, and the hollow part of the column 100, and finally passes out through the lower end opening of the threaded pipe 130 for subsequent connection with other circuit control components, such as solenoid valves of the first water pipe 110 and the second water pipe 120.

[0055] Preferably, a water-vapor separation box 750 or a microbubble bubbler 450 is provided at the upper water outlet 711 and the lower water outlet 411. In this embodiment, the water-vapor separation box 750 is provided at the upper water outlet 711 of the upper swing arm 700, and the microbubble bubbler 450 is provided at the lower water outlet 411 of the lower swing arm 400. Providing the water-vapor separation box 750 or the microbubble bubbler 450 at the upper water outlet 711 and the lower water outlet 411 can, on the one hand, fully mix the water flow with air to form a water flow rich in microbubbles, making the water outlet softer, reducing water splash, and improving the use experience; on the other hand, the optimized water flow appearance is more beautiful, enhancing the quality sense of the product.

[0056] Preferably, an annular exhaust groove 221 is provided on the outer peripheral side of the lower fixed joint 200 below the first water channel 231. An exhaust nozzle 330 communicating with the exhaust groove 221 is provided on the outer peripheral side of the lower movable joint 300. An exhaust channel 460 connected to the exhaust nozzle 330 is provided inside the lower swing arm 400. The end of the exhaust channel 460 forms an exhaust port 461. An exhaust pipe 140 communicating with the exhaust groove 221 is provided inside the column 100.

[0057] In this embodiment, the exhaust channel 460 is formed by connecting PE hoses and extends to the middle of the lower end of the lower water outlet arm 430. A dust-proof plug 462 is also provided at the position of the exhaust port 461. The extended height of the lower rotating sleeve 420 can cover the exhaust section 220 and the water outlet section 230.

[0058] Preferably, as Figure 4 , 5 shown, sealing ring grooves 250 for installing sealing rings are provided on the outer peripheral sides 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. Sealing rings are provided in the sealing ring grooves 250. Through the above-mentioned sealing ring grooves 250 and the sealing rings, further sealing of the first water channel 231 and the second water channel 510 can be achieved, and the rotation process of the upper swing arm 700 and the lower swing arm 400 can be made smoother.

[0059] The beneficial effects of the present invention are as follows: The present invention realizes the rotational water outlet between the upper swing arm 700 and the lower swing arm 400 through the inner and outer ring water channels formed between the lower fixed joint 200 fixed above, the upper fixed joint 500, the lower movable joint 300 and the upper movable joint 600. Thus, the upper swing arm 700 and the lower swing arm 400 can independently rotate to different positions to discharge water, meeting the diverse water use requirements in the same space and greatly improving the convenience and flexibility of water use.

[0060] Meanwhile, for places with limited installation space, the double-outlet faucet structure of the present invention can also effectively make up for it, significantly improving the convenience and efficiency of water use and broadening the applicable range of faucet products.

[0061] In addition, through the position sensing component 440 arranged between the upper swing arm 700 and the lower swing arm 400, the present invention can automatically cut off the water path when the two overlap, avoiding the water outlet interference generated when the upper swing arm 700 and the lower swing arm 400 overlap.

[0062] In addition, the design of the wire threading joint 800 provides great convenience for wire layout. A wire threading opening 850 with a certain angular range is opened on the lower swing arm 400 where the cable 910 needs to be arranged, so as to stably connect the wires in cooperation with the rotation of the lower swing arm 400 and stably realize the overlap monitoring between the upper swing arm 700 and the lower swing arm 400.

[0063] In addition, sealing ring grooves 250 for installing sealing rings are provided on the upper and lower sides of the outer peripheral sides of the upper fixed joint 500 and the lower fixed joint 200 in the first water channel 231 and the second water channel 510. By installing the sealing rings, it can effectively prevent water leakage at the water channel connection, ensuring the sealing and stability of the entire faucet structure, improving the product quality, and reducing the maintenance cost and inconvenience caused by water leakage problems.

[0064] Particularly, the exhaust groove 221 on the outer peripheral side of the lower fixed joint 200, in cooperation with the exhaust nozzle 330 on the outer peripheral side of the lower movable joint 300, the exhaust channel 460 in the lower swing arm 400 and the exhaust pipe 140 in the column 100, can timely discharge the air in the water pipe, effectively avoiding the generation of air resistance phenomenon, ensuring the stable and smooth water flow, prolonging the service life of the faucet, and improving the product performance.

[0065] The present invention has been described exemplarily above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
