[0002] In the sanitary ware industry, the water outlet device is an important part of sanitary facilities, which directly affects the user experience and the comfort of the sanitary space. The spray bar is a relatively common water outlet device, widely used in equipment such as shower heads and bidets. Traditional spray bars usually adopt a single-waterway design, providing basic water flow through fixed nozzles. With the increasing requirements of consumers for sanitary experience, the single-waterway spray bar can no longer meet the market's demand for personalization and versatility.

[0003] The single-waterway design of traditional spray bars limits the diversity of water flow patterns and cannot provide a personalized cleaning experience. Moreover, the water volume and water pressure adjustment of existing spray bars are usually relatively fixed, lacking a flexible adjustment mechanism, making it difficult for users to adjust according to personal preferences. At the same time, the single waterway cannot achieve the mixing of different water volume ratios, limiting the possibility for users to enjoy various water types (such as pulsed water, atomized water, etc.).

[0004] Due to the limitations of functions and adjustments, existing spray bars cannot provide a rich cleaning experience, affecting user satisfaction and comfort. Summary of the Utility Model

[0041] Reference Figures 1 - 12 , this embodiment provides a dual-waterway water outlet device. The water outlet device includes a device body 1, a spray rod assembly 2 and a spray head assembly 3 arranged in the device body 1.

[0042] The device body 1 is a hollow tube. The spray rod assembly 2 is movably arranged in the device body 1 and has telescopic movement along the length direction of the device body 1. The spray head assembly 3 is installed at the telescopic end of the spray rod assembly 2. First water inlet joints 11 and second water inlet joints 12 are arranged at different positions of the device body 1. The first water inlet joint 11 is arranged at the rear end of the device body 1, and the second water inlet joint 12 is arranged at a position close to the front end of the device body 1. The front end port of the device body 1 is used for the telescopic movement of the spray rod assembly 2.

[0043] The first water inlet joint 11 is an end cover 33 type joint, which is used for spiral installation at the port of the rear end of the device body 1. An inlet joint gasket 13 is arranged between the first water inlet joint 11 and the device body 1 when they are screwed together to form a sealing structure to prevent water leakage. The second water inlet joint 12 is integrally arranged with the device body 1. A pipe protrudes outward from the side wall of the device body 1 to form the second water inlet joint 12. Both the first water inlet joint 11 and the second water inlet joint 12 are used for connecting to an external water system to supply water to the water outlet device.

[0044] The spray bar assembly 2 includes a spray bar 21, an elastic member, a first seal 23, a second seal 24, and an inner tube 25. The first seal 23 and the second seal 24 are gasket seals, and the elastic member is a return spring 22. The inner tube 25 is disposed inside the spray bar 21. The inner tube 25 has a hollow structure, and a first water passage 4 is formed inside the inner tube 25. A gap is provided between the outer wall of the inner tube 25 and the inner wall of the spray bar 21 to form a second water passage 5. The first water passage 4 and the second water passage 5 are independent water chamber structures. The first water passage 4 and the second water passage 5 are respectively connected to the nozzle assembly 3, and a first water passage seal ring 41 and a second water passage seal ring 51 are provided at the connection ends of the first water passage 4, the second water passage 5, and the nozzle assembly 3 to form a sealing structure to prevent water leakage.

[0045] The nozzle assembly 3 includes a nozzle body 31, a water distribution plate 32, an end cap 33, and a nozzle decorative cover 34. The nozzle body 31 includes a first water passage 311, a second water passage 312, a third water passage 313, and a water inlet groove 314. The water inlet groove 314 is connected to the third water passage 313. The third water passage 313 is connected to the second water passage 312. The second water passage 312 is connected to the second water passage 5. The end cap 33 includes an end cap water passage 331 and a water inlet hole 332. The end cap water passage 331 passes through the water distribution plate 32 and is connected to the first water passage 311. The first water passage 311 is connected to the first water passage 4. The nozzle body 31 includes a mixing chamber 315 and a water outlet 316. The mixing chamber 315 is respectively connected to the water inlet hole 332 and the water inlet groove 314. By adjusting the water flow ratio of the first water passage 4 and the second water passage 5, mixed water is formed in the mixing chamber 315 and then sprayed out from the water outlet 316. Different water flow ratios can form different water patterns, realizing the functions of single-hole multi-water patterns and arbitrarily adjusting the water patterns.

[0046] In this embodiment, the structure for realizing dual-waterway water inlet is to utilize the telescopic cooperation of the spray bar assembly 2 to achieve dual-waterway water inlet, and the telescopic movement of the spray bar assembly 2 is realized through the cooperation of water pressure drive and the return spring 22.

[0047] The specific structure is that the spray bar 21 is sleeved inside the hollow tube of the device body 1, and one end of the spray bar 21 where the nozzle assembly 3 is installed extends out from the front end port of the device body 1. A return spring 22 is sleeved on the outer circumference of the spray bar 21. One end of the return spring 22 abuts against the inner edge of the front end port, and the other end of the return spring 22 is fixed to the end of the spray bar 21 away from the nozzle assembly 3.

[0048] One end of the spray boom 21 away from the nozzle assembly 3 is set as a closed end, and a first water inlet 211 and a second water inlet 212 are provided near the closed end. The first water inlet 211 and the second water inlet 212 are arranged at different positions on the body of the spray boom 21 at intervals. The first water inlet 211 is communicated with the first water path 4, and the second water inlet 212 is communicated with the second water path 5. The spray boom 21 is provided with a first annular platform 213, a second annular platform 214 and a third annular platform 215 at intervals on the outer periphery of one end of its closed end. The first annular platform 213 is flush with the closed end of the spray boom 21. The second annular platform 214 and the third annular platform 215 are oppositely arranged on both sides of the second water inlet 212, and the second annular platform 214 is arranged between the first water inlet 211 and the second water inlet 212. The second annular platform 214 is provided with a clamping groove for fixing the first seal 23, and the third annular platform 215 is used for fixing the second seal 24. The first seal 23 and the second seal 24 are installed in a nested manner. The first water inlet 211 and the second water inlet 212 are isolated by the first seal 23 and the second seal 24, so that the first water path 4 and the second water path 5 form two independent water cavities. In this embodiment, it is preferably to select two seals, or only the first seal 23 can be arranged on the second annular platform 214 to isolate the first water inlet 211 and the second water inlet 212. In other words, in this embodiment, at least one sealing element is arranged between the first water inlet 211 and the second water inlet 212 to form two independent water cavities.

[0049] The closed end of the spray boom 21 can move back and forth along the inner wall of the hollow tube of the device body 1, and the closed end forms a first gap 6 with the inner wall of the device body 1 by using the first annular platform 213. The first gap 6 cannot pass through under normal water flow, and can only flow out through the first gap 6 when the water flow is in an overfilled state in the device body 1. The first gap 6 is communicated with the first water inlet 211. A second gap 7 is formed between the front end port of the device body 1 and the body of the spray boom 21. The second gap 7 is used for squeezing and discharging the excess water after the water inlet in the device body 1 stops. The second gap 7 is communicated with the inner cavity of the hollow tube of the device body 1 and the outside.

[0050] At a distance from the front end port of the device body 1, a first sealing surface 14 and a second sealing surface 15 are convexly arranged inward. The first sealing surface 14 and the second sealing surface 15 are arranged in a ring shape. The first sealing surface 14 is used for fitting with the first seal 23, and the second sealing surface 15 is used for fitting with the second seal 24 to form a sealing structure.

[0051] The first seal 23 fits with the first sealing surface 14 to isolate the communication between the first water inlet 211 and the second water inlet 212. The first seal 23 fits with the first sealing surface 14 and cooperates with the second seal 24 to fit with the second sealing surface 15 to form a sealing structure on both sides of the second water inlet 212 to prevent water leakage when the second water inlet 212 intakes water.

[0052] In this embodiment, the water inlet direction of the second waterway 5 is set at an angle with the device body 1, and the angle range is set between 0° and 180°, preferably 90°, which is convenient for the arrangement of waterway connections.

[0053] The specific operation of the hydraulic drive spray bar 21 to achieve double-waterway water inlet is as follows. When the first water inlet joint 11 does not let water in, the spray bar 21 retracts into the device body 1 under the action of the return spring 22, and the closed end of the spray bar 21 abuts against the inner surface of the end cover 33 of the first water inlet joint 11. This is the initial state of the spray bar assembly 2. In the initial state, since the second water inlet 212 is arranged near the closed end, and the second water inlet joint 12 is arranged at the front end of the device body 1, the second water inlet 212 and the second water inlet joint 12 are in a misaligned state.

[0054] When the first water inlet joint 11 starts to let water in, the water source enters the device body 1 from the first water inlet joint 11. Since this end of the spray bar 21 is a closed-end structure, the water flow cannot be discharged after entering, generating water pressure. The water pressure cooperates with the closed end to push the spray bar 21 to squeeze the return spring 22 and move outward. The spray bar 21 moves outward until the first seal 23 and the second seal 24 are respectively in contact with and fit on the first sealing surface 14 and the second sealing surface 15 to form a sealing structure. At this time, the spray bar 21 moves to a position where the second water inlet 212 is communicated with the second water inlet joint 12, and the spray bar 21 stops moving. At this time, the second water inlet 212 is communicated with the second water inlet joint 12.

[0055] After the spray bar 21 stops moving, the first water inlet joint 11 continues to let water in, and the inner cavity of the hollow tube of the device body 1 is filled with water. The water starts to flow from the first gap 6 into the first water inlet 211, thereby supplying water to the first waterway 4. At the same time, the water supply of the second water inlet joint 12 can be opened to achieve double-waterway water inlet, adjust the water volume ratio of the first waterway 4 and the second waterway 5, and form various water outlet patterns. By adjusting the ratio of the two-way water volume, various water patterns can be obtained, improving the experience.

[0056] In this embodiment, the specific implementation process of the double-waterway water outlet device is as follows. The water source enters the water outlet device from the first water inlet joint 11, and the water pressure is used in the device body 1 to push the spray bar assembly 2 to move forward and extend out of the device body 1. When the sealing surfaces of the first seal 23 and the second seal 24 are respectively in contact with and fit on the first sealing surface 14 and the second sealing surface 15 of the device body 1 to form a sealing structure, the spray bar assembly 2 stops moving.

[0057] After the boom assembly 2 stops moving, the first water inlet joint 11 continues to supply water. Due to the sealing performance of the first seal 23, water flows out of the first water inlet 211 through the first gap 6 and enters the first water path 4 of the inner tube 25. The water flows from the first water path 4 into the nozzle assembly 3, flows from the first water path 4 into the first water channel 311, passes through the water distribution plate 32 into the end cover water channel 331, and flows into the mixing chamber 315 through the water inlet hole 332.

[0058] The second water inlet joint 12 starts to supply water. Water flows from the second water inlet joint into the second water inlet 212, and then into the second water path 5. Then it flows into the nozzle assembly 3 from the second water path 5. The water flows from the second water path 5 to the second water channel 312 and the third water channel 313, and flows into the mixing chamber 315 through the water inlet groove 314. The water flow in the first water path 4 and the water flow in the second water path 5 are mixed in the mixing chamber 315 and then sprayed out from the water outlet 316 of the nozzle. Adjusting the flow ratio of the water flow in the first water path 4 and the water flow in the second water path 5 can form different water patterns, and the adjustment of the two-way water volume ratio can be realized to obtain a variety of water patterns, improving the experience. There are multiple water patterns for a single hole, and the water pattern can be adjusted arbitrarily.

[0059] After the first water inlet joint 11 and the second water inlet joint 12 stop supplying water, under the action of the return spring 22 of the boom assembly 2, the first seal 23 and the second seal 24 are separated from the first sealing surface 14 and the second sealing surface 15. At this time, the water remaining in the device body 1 can be discharged through the second gap 7, and the boom assembly 2 is reset to the initial state.

[0060] The above is only the preferred specific implementation mode of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, making non-substantive changes to the present invention using this concept, shall fall within the scope of infringement of the protection of the present invention.
