[0050] Referring to FIGS. 1-17, the present embodiment provides a double waterway water outlet device, which comprises a device body 1 and a spray rod assembly 2 and a spray head assembly 3 arranged in the device body 1.

[0051] 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, and the spray head assembly 3 is installed at the telescopic end of the spray rod assembly 2. The first water inlet joint 11 and the second water inlet joint 12 are arranged at different positions of the device body 1, wherein 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 telescopic movement of the spray rod assembly 2.

[0052] The first water inlet joint 11 is a cap joint, which is screwed into the port at the rear end of the device body 1, and a water inlet joint sealing gasket 13 is arranged between the first water inlet joint 11 and the device body 1 to form a sealing structure to prevent water leakage. The second water inlet joint 12 is integrally arranged with the device body 1, and the pipeline of the second water inlet joint 12 is arranged outwardly protruding from the side wall of the device body 1. The first water inlet joint 11 and the second water inlet joint 12 are both used for connecting the waterway system to supply water to the water outlet device.

[0053] The spray rod assembly 2 includes a spray rod 21, an elastic member, a first sealing member 23, a second sealing member 24, and an inner tube 25. The first sealing member 23 and the second sealing member 24 are sealing gaskets, and the elastic member is a return spring 22. The inner tube 25 is built in the spray rod 21. The inner tube 25 has a hollow structure, and a first waterway 4 is formed in the inner tube 25. A gap is arranged between the outer wall of the inner tube 25 and the inner wall of the spray rod 21 to form a second waterway 5. The first waterway 4 and the second waterway 5 are independent water cavity structures. The first waterway 4 and the second waterway 5 are respectively connected to the spray head assembly 3, and a first waterway sealing ring 41 and a second waterway sealing ring 51 are arranged at the connection end of the first waterway 4, the second waterway 5, and the spray head assembly 3 to form a sealing structure to prevent water leakage.

[0054] The spray head assembly 3 comprises a spray head body 31, a water distribution disc 32, an end cover 33 and a spray head decorative cover 34. The spray head body 31 comprises a first water channel 311, a second water channel 312, a third water channel 313 and a water inlet groove 314. The water inlet groove 314 is connected to the third water channel 313, the third water channel 313 is connected to the second water channel 312, and the second water channel 312 is connected to the second waterway 5. The end cover 33 comprises an end cover water channel 331 and a water inlet hole 332. The end cover water channel 331 is connected to the first water channel 311 through the water distribution disc 32, and the first water channel 311 is connected to the first waterway 4. The spray head body 31 comprises a mixing chamber 315 and a water outlet 316. The mixing chamber 315 is connected to the water inlet hole 332 and the water inlet groove 314 respectively. The water inlet hole 332 is connected to the mixing chamber 315 along the axial direction of the mixing chamber 315, and the water inlet groove 314 is connected to the mixing chamber 315 along the tangential direction of the mixing chamber 315. Therefore, the water flow entering the mixing chamber 315 through the water inlet groove 314 is vortex water, and the water flow entering the mixing chamber through the water inlet hole 332 is straight water. By adjusting the water flow ratio of the first waterway 4 and the second waterway 5, the proportion of vortex water and straight water can be adjusted, and mixed water is formed in the mixing chamber 315 and sprayed out of the water outlet 316. Different water flow ratios can form different water types, realize single-hole multi-water type, and randomly adjust the water type.

[0055] In order to realize the adjustment of the water flow ratio of the first waterway 4 and the second waterway 5, the water distribution valve assembly 8 is further included in the embodiment. The water distribution valve assembly 8 is used to adjust the water flow ratio of the first water inlet connector 11 and the second water inlet connector 12, so as to adjust the water flow ratio of the first waterway 4 and the second waterway 5.

[0056] Specifically, the water distribution valve assembly 8 comprises a valve body, a dynamic sliding sheet 81 and a static sliding sheet 82. The dynamic sliding sheet 81 rotates relative to the static sliding sheet 82 under the action of an external force. The dynamic sliding sheet 81 is provided with a water inlet hole 811, and the static sliding sheet 82 is provided with a first water passing hole 821 and a second water passing hole 822 connected to the first waterway 4 and the second waterway 5 respectively. The external force can be applied by a user, that is, the user actively adjusts the position of the dynamic sliding sheet 81 to adjust the water flow.

[0057] For example, when the moving slide 81 is in the first position, the water inlet 811 is misaligned with the first water passage 821 and the second water passage 822; at this time, neither the first water passage 4 nor the second water passage 5 is supplied with water, and the spray head assembly 3 does not spray water. When the moving slide 81 is in the second position, the water inlet 811 is in communication with the first water passage 821 and misaligned with the second water passage 822; at this time, all the water flows out from the water inlet hole 332, which is the straight jet water effect. When the moving slide 81 is in the third position, the water inlet 811 is in communication with the first water passage 821 and the second water passage 822 respectively; at this time, part of the water is vortex water and part of the water is mixed water, so the water spray is different from that when the moving slide 81 is in the second position. After the moving slide 81 is in the third position, the moving slide 81 can be continuously rotated; at this time, the communication area of the water inlet 811 with the first water passage 821 gradually decreases, and the communication area of the water inlet 811 with the second water passage 822 gradually increases, so that the proportion of the straight jet water can be decreased and the proportion of the vortex water can be increased.

[0058] In the embodiment, the structure for realizing the double water passage water inlet is that the double water passage water inlet is realized by the telescopic cooperation of the spray rod assembly 2, and the telescopic cooperation of the spray rod assembly 2 is realized by the cooperation of the water pressure drive and the reset spring 22.

[0059] Specifically, the spray rod 21 is sleeved in the hollow pipe of the device body 1, and the end of the spray rod 21, on which the spray head assembly 3 is installed, is stretched out from the front end port of the device body 1; the reset spring 22 is sleeved on the outer periphery of the spray rod 21, one end of the reset spring 22 abuts against the inner edge of the front end port, and the other end of the reset spring 22 is fixed on the end of the spray rod 21, which is away from the spray head assembly 3.

[0060] The end of the spray bar 21 furthest from the nozzle assembly 3 is designated as a closed end, and a first water inlet 211 and a second water inlet 212 are provided near this closed end. The first water inlet 211 and the second water inlet 212 are spaced apart at different positions on the body of the spray bar 21. The first water inlet 211 is connected to the first water passage 4, and the second water inlet 212 is connected to the second water passage 5. On the outer periphery of the closed end of the spray bar 21, a first annular platform 213, a second annular platform 214, and a third annular platform 215 are spaced apart. The first annular platform 213 is flush with the closed end of the spray bar 21. The second annular platform 214 and the third annular platform 215 are positioned opposite each other on both sides of the second water inlet 212, with the second annular platform 214 positioned between the first water inlet 211 and the second water inlet 212. The second annular platform 214 has a groove for fixing the first seal 23, and the third annular platform 215 is used to fix the second seal 24. The first seal 23 and the second seal 24 are installed in a nested manner, isolating the first water inlet 211 and the second water inlet 212, thus forming two independent water chambers in the first water passage 4 and the second water passage 5. In this embodiment, it is preferred to use two seals, but alternatively, only the first seal 23 can be used 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 provided between the first water inlet 211 and the second water inlet 212 to form two independent water chambers.

[0061] The closed end of the spray bar 21 can move back and forth along the inner wall of the hollow tube of the device body 1. The closed end forms a first gap 6 with the inner wall of the device body 1 through the first annular platform 213. The first gap 6 cannot pass through under normal water flow. It can only flow out through the first gap 6 when the water flow is in an interference state inside the device body 1. The first gap 6 is connected to the first water inlet 211. A second gap 7 is formed between the front end of the device body 1 and the rod of the spray bar 21. The second gap 7 is used to squeeze out excess water after the water inlet in the device body 1 stops. The second gap 7 is connected to the inner cavity of the hollow tube of the device body 1 and the outside.

[0062] The device body 1 has a first sealing surface 14 and a second sealing surface 15 protruding inward at a distance from the front end port. The first sealing surface 14 and the second sealing surface 15 are arranged in a ring. The first sealing surface 14 is used to fit with the first sealing element 23, and the second sealing surface 15 is used to fit with the second sealing element 24 to form a sealing structure.

[0063] The first sealing element 23 fits into the first sealing surface 14, isolating the first water inlet 211 from the second water inlet 212. The first sealing element 23 fits into the first sealing surface 14, and the second sealing element 24 fits into the second sealing surface 15, forming a sealing structure on both sides of the second water inlet 212 to prevent water leakage when water enters the second water inlet 212.

[0064] In the embodiment, the water inlet direction of the second waterway 5 is arranged at an angle with the device body 1, and the angle is arranged in the range of 0°-180°, and preferably arranged at 90°, facilitating the waterway connection arrangement.

[0065] The specific operation of the water-driven spray rod 21 to realize double waterway water inlet is that when the first water inlet connector 11 does not inlet water, the spray rod 21 is retracted in the device body 1 under the action of the reset spring 22, and the closed end of the spray rod 21 abuts on the inner surface of the end cover of the first water inlet connector 11, which is the initial state of the spray rod assembly 2. In the initial state, since the second water inlet 212 is arranged close to the closed end, and the second water inlet connector 12 is arranged at the front end of the device body 1, the second water inlet 212 and the second water inlet connector 12 are in a staggered state.

[0066] When the first water inlet connector 11 starts to inlet water, the water source enters the device body 1 from the first water inlet connector 11. Since the end of the spray rod 21 is a closed end structure, the water flow cannot be discharged after entering, and water pressure is generated. The water pressure cooperates with the closed end to push the spray rod 21 to extrude the reset spring 22 to move outward. The spray rod 21 moves outward until the first sealing element 23 and the second sealing element 24 are respectively attached to the first sealing surface 14 and the second sealing surface 15 to form a sealing structure. At this time, the spray rod 21 moves to the second water inlet 212 and the second water inlet connector 12 to be connected, and the spray rod 21 stops moving. At this time, the second water inlet 212 and the second water inlet connector 12 are connected in airtight connection to form an independent waterway.

[0067] After the spray rod 21 stops moving, the first water inlet connector 11 continues to inlet water, and the hollow pipe cavity of the device body 1 is filled with water. The water starts to flow into the first water inlet 211 from the first gap 6, so as to pass water to the first waterway 4. At the same time, the second water inlet connector 12 can be opened to pass water, realizing double waterway water inlet. By adjusting the water quantity ratio of the first waterway 4 and the second waterway 5, various water types can be formed, the adjustment of the two-way water quantity ratio is realized to obtain various water types, and the experience is improved.

[0068] In the embodiment, the specific implementation process of the double waterway water outlet device is that the water source enters the water outlet device from the first water inlet connector 11. In the device body 1, the spray rod assembly 2 is pushed forward by water pressure to move out of the device body 1. When the sealing surface of the first sealing element 23 and the sealing surface of the second sealing element 24 respectively contact and attach to the first sealing surface 14 and the second sealing surface 15 of the device body 1 to form a sealing structure, the spray rod assembly 2 stops moving.

[0069] After the spray rod assembly 2 stops moving, the first water inlet joint 11 continues to supply water, and due to the sealing property of the first sealing element 23, the water flows out of the first water inlet 211 from the first gap 6 and enters the first water channel 4 of the inner pipe 25, the water flows from the first water channel 4 into the spray head assembly 3, the water flows from the first water channel 4 into the first water channel 311, flows into the end cover water channel 331 through the water distribution disc 32, and flows into the mixing cavity 315 through the water inlet hole 332.

[0070] The second water inlet joint 12 starts to supply water, the water flows from the second water inlet joint 12 into the second water inlet 212 and into the second water channel 5, and then flows from the second water channel 5 into the spray head assembly 3, the water flows from the second water channel 5 to the second water channel 312 and the third water channel 313, and flows into the mixing cavity 315 through the water inlet groove 314.

[0071] When the first water inlet joint 11 and the second water inlet joint 12 stop supplying water, the spray rod assembly 2 is reset under the action of the reset spring 22, the first sealing element 23 and the second sealing element 24 are separated from the first sealing surface 14 and the second sealing surface 15, at this time, the residual water in the device body 1 can be discharged through the second gap 7, and the spray rod assembly 2 is reset to the initial state.

[0072] The above is only a preferred specific embodiment of the present application, but the design concept of the present application is not limited thereto, and any person skilled in the art can make non-essential changes to the present application within the technical scope disclosed by the present application, which is an act of infringing the protection scope of the present application.
