A dual-water-path water outlet device

Abstract

This utility model provides a dual-water-path water outlet device, including a device body and a first water inlet connector and a second water inlet connector. A spray bar assembly and a nozzle assembly are disposed within the device body. The spray bar assembly includes a spray bar and an elastic element. The spray bar has a first water path and a second water path, and its shaft has a first water inlet connecting the first water path and a second water inlet connecting the second water path. The nozzle assembly is installed at one end of the spray bar, and the other end is a closed end. When water begins to enter through the first water inlet connector, the water pressure, combined with the closed end, pushes the spray bar to compress the elastic element outwards until it connects with the second water inlet connector. A first gap is formed between the closed end of the spray bar and the device body, causing the spray bar to stop moving, and water flows through the first gap into the first water inlet connector. The device also includes a water distribution valve assembly, which is used to adjust the ratio of water flow entering the first water inlet connector and the second water inlet connector.

Description

Technical Field

[0001] This utility model relates to water outlet equipment in the sanitary ware industry, and more particularly to a dual water outlet device. Background Technology

[0002] In the bathroom industry, water outlet devices are a crucial component of bathroom facilities, directly impacting the user experience and the comfort of the bathroom space. Sprayers are a common type of water outlet device, widely used in shower heads, bidets, and other similar devices. Traditional sprayers typically employ a single water path design, providing basic water flow through a fixed nozzle. However, as consumers' demands for a superior bathroom experience increase, single-water-path sprayers can no longer meet the market's needs for personalization and multi-functionality.

[0003] The single water path design of traditional spray bars limits the diversity of water flow patterns and fails to provide a personalized cleaning experience. Furthermore, the water volume and 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 water path cannot achieve the mixing of different water ratios, limiting the possibility for users to enjoy various water types (such as pulse water, atomized water, etc.).

[0004] Due to limitations in functionality and adjustment, existing spray booms cannot provide a rich cleaning experience, affecting user satisfaction and comfort. Utility Model Content

[0050] refer to Figures 1-17 This embodiment provides a dual-water-path water outlet device, which includes a device body 1 and a spray bar assembly 2 and a nozzle assembly 3 disposed within the device body 1.

[0051] The device body 1 is a hollow tube. The spray bar assembly 2 is movably disposed within the device body 1 and has telescopic movement along the length of the device body 1. The nozzle assembly 3 is installed at the telescopic end of the spray bar assembly 2. A first water inlet connector 11 and a second water inlet connector 12 are provided at different positions on the device body 1. The first water inlet connector 11 is located at the rear end of the device body 1, and the second water inlet connector 12 is located near the front end of the device body 1. The front end of the device body 1 is used for the telescopic movement of the spray bar assembly 2.

[0052] The first water inlet connector 11 is an end cap type connector, used for screwing and installing at the port at the rear end of the device body 1, and a water inlet connector sealing gasket 13 is provided between the first water inlet connector 11 and the device body 1.

[0053] A sealed structure is formed to prevent water leakage. The second water inlet connector 12 is integrally set with the device body 1. A pipe is set outward on the side wall of the device body 1 to form the second water inlet connector 12. Both the first water inlet connector 11 and the second water inlet connector 12 are used to connect to an external water system to supply water to the water outlet device.

[0054] The spray bar assembly 2 includes a spray bar 21, an elastic element, a first seal 23, a second seal 24, and an inner tube 25. The first seal 23 and the second seal 24 are sealing gaskets, and the elastic element is a return spring 22. The inner tube 25 is built inside the spray bar 21 and has a hollow structure. A first water channel 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 channel 5. The first water channel 4 and the second water channel 5 are independent water chamber structures. The first water channel 4 and the second water channel 5 are respectively connected to the nozzle assembly 3, and a first water channel sealing ring 41 and a second water channel sealing ring 51 are provided at the connection ends of the first water channel 4 and the second water channel 5 with the nozzle assembly 3 to form a sealing structure and prevent water leakage.

[0055] The nozzle assembly 3 includes a nozzle body 31, a water distribution plate 32, an end cap 33, and a nozzle decorative cap 34. The nozzle body 31 includes 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, and the third water channel 313 is connected to the second water channel 312. The second water channel 312 is connected to the second water passage 5. The end cap 33 includes an end cap water channel 331 and a water inlet hole 332. The end cap water channel 331 is connected to the first water channel 311 via the water distribution plate 32, and the first water channel 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 connected to a water inlet 332 and a water inlet channel 314. The water inlet 332 is connected to the mixing chamber 315 along its axial direction, and the water inlet channel 314 is connected to the mixing chamber 315 tangentially. Therefore, the water flow entering the mixing chamber 315 through the water inlet channel 314 is vortex water, and the water flow entering the mixing chamber through the water inlet 332 is direct jet water. By adjusting the water flow ratio between the first water channel 4 and the second water channel 5, the ratio of vortex water and direct jet water can be adjusted. After the mixed water is formed in the mixing chamber 315, it is sprayed out from the water outlet 316. Different water flow ratios can form different water patterns, realizing the function of multiple water patterns in a single hole and arbitrarily adjusting the water pattern.

[0056] In order to adjust the ratio of water flow into the first water path 4 and the second water path 5, this embodiment also includes a water distribution valve assembly 8. The water distribution valve assembly 8 is used to adjust the ratio of water flow into the first water inlet connector 11 and the second water inlet connector 12, which can also adjust the water flow into the first water path 4 and the second water path 5.

[0057] Specifically, the water distribution valve assembly 8 includes a valve body, a movable slide plate 81, and a stationary slide plate 82; the movable slide plate 81 rotates relative to the stationary slide plate 82 under the action of an external force; the movable slide plate 81 is provided with a water inlet 811, and the stationary slide plate 82 is provided with a first water outlet 821 and a second water outlet 822 respectively connecting the first water passage 4 and the second water passage 5; the external force can be applied by the user, that is, the user actively adjusts the position of the movable slide plate 81, thereby adjusting the water flow.

[0058] For example, when the movable vane 81 is in the first position, the water inlet 811 is offset from the first water outlet 821 and the second water outlet 822; at this time, neither the first water path 4 nor the second water path 5 receives water, and the nozzle assembly 3 does not discharge water. When the movable vane 81 is in the second position, the water inlet 811 is connected to the first water outlet 821 and offset from the second water outlet 822; at this time, all the water flows out from the water inlet 332, resulting in a direct jet effect. When the movable vane 81 is in the third position, the water inlet 811 is connected to both the first water outlet 821 and the second water outlet 822; at this time, some of the water is vortex water and some is mixed water, thus the water spray is different from that when the movable vane 81 is in the second position. Furthermore, after the movable slide 81 is in the third position, the movable slide 81 can continue to rotate. At this time, the connection area between the water inlet 811 and the first water outlet 821 gradually decreases, while the connection area between the water inlet 811 and the second water outlet 822 gradually increases. This can reduce the proportion of direct water flow and increase the proportion of vortex water flow.

[0059] In this embodiment, the structure for achieving dual water inlet is achieved by utilizing the telescopic cooperation of the spray bar assembly 2, and the telescopic cooperation of the spray bar assembly 2 is achieved by the cooperation of water pressure drive and return spring 22.

[0060] The specific structure is as follows: the spray bar 21 is fitted inside the hollow tube of the device body 1, and one end of the spray bar 21 that is fitted with the nozzle assembly 3 extends out from the front end port of the device body 1. A return spring 22 is fitted on the outer periphery 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 on the end of the spray bar 21 away from the nozzle assembly 3.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] In this embodiment, the water inlet direction of the second water channel 5 is set at a certain angle to the device body 1. The certain angle range is set between 0° and 180°, and the preferred angle is set at 90°, which facilitates the connection and arrangement of the water channels.

[0066] The specific operation of the water-driven spray bar 21 to achieve dual water inlet is as follows: when the first water inlet connector 11 does not receive water, the spray bar 21 is retracted 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 cap of the first water inlet connector 11. This is the initial state of the spray bar assembly 2. In the initial state, since the second water inlet 212 is located near the closed end, and the second water inlet connector 12 is located at the front end of the device body 1, the second water inlet 212 and the second water inlet connector 12 are misaligned.

[0067] When water begins to enter through the first water inlet connector 11, the water source enters the device body 1 from the first water inlet connector 11. Since this end of the spray rod 21 is a closed-end structure, the water cannot be discharged after entering, generating water pressure. The water pressure, combined with the closed end, pushes the spray rod 21 to squeeze the return spring 22 and move it outward. The spray rod 21 moves outward until the first sealing element 23 and the second sealing element 24 are respectively in contact with the first sealing surface 14 and the second sealing surface 15, forming a sealing structure. At this time, the spray rod 21 moves to the second water inlet 212 and connects with the second water inlet connector 12, and the spray rod 21 stops moving. At this time, the second water inlet 212 and the second water inlet connector 12 are connected. It should be noted that when the spray rod 21 moves to the second water inlet 212 and connects with the second water inlet connector 12, it means that the second water inlet 212 and the second water inlet connector 12 are sealed together to form an independent water channel.

[0068] After the spray bar 21 stops moving, the first water inlet connector 11 continues to supply water, and the hollow tube cavity of the device body 1 is filled with water. Water begins to flow from the first gap 6 into the first water inlet 211, thus supplying water to the first water path 4. At the same time, the second water inlet connector 12 can be opened to supply water, realizing dual water path water supply. By adjusting the water volume ratio of the first water path 4 and the second water path 5, various water patterns can be formed, thereby achieving the adjustment of the water volume ratio of the two paths to obtain various water patterns and improve the user experience.

[0069] In this embodiment, the specific implementation process of a dual-water-path water outlet device is as follows: water source enters the water outlet device from the first water inlet connector 11, and water pressure pushes the spray bar assembly 2 forward within the device body 1, extending it out of the device body 1. When the sealing surface of the first sealing member 23 and the sealing surface of the second sealing member 24 respectively contact and adhere to 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.

[0070] After the spray bar assembly 2 stops moving, the first water inlet connector 11 continues to supply water. Due to the sealing of the first seal 23, the water flows out of the first water inlet 211 from the first gap 6 and enters the first water passage 4 of the inner tube 25. The water flows into the nozzle assembly 3 from the first water passage 4, and then into the first water channel 311 from the first water channel 4. After passing through the water distribution plate 32, the water flows into the end cover water channel 331 and into the mixing chamber 315 through the water inlet hole 332.

[0071] Water begins to enter through the second inlet connector 12, flowing into the second inlet port 212 and then into the second water path 5. From there, it flows into the nozzle assembly 3, then into the second water channel 312 and the third water channel 313, and finally into the mixing chamber 315 via the inlet trough 314. The water flow from the first water path 4 and the second water path 5 mix in the mixing chamber 315 and is then sprayed out from the nozzle outlet 316. Adjusting the flow rate ratio between the first and second water paths allows for different water patterns to be created, enabling adjustment of the two water flow ratios to achieve various water patterns and enhance the user experience. A single nozzle offers multiple water patterns, allowing for easy adjustment of the water pattern.

[0072] When the first water inlet connector 11 and the second water inlet connector 12 stop supplying water, the first seal 23 and the second seal 24 are separated from the first sealing surface 14 and the second sealing surface 15 under the action of the return spring 22. At this time, the water remaining in the device body 1 can be discharged through the second gap 7, and the spray bar assembly 2 is reset to the initial state.

[0073] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
