Description

Technical Field

[0001] This utility model relates to a water outlet device that can quickly stop water flow. Background Technology

[0002] Overhead showers or faucets are common water outlets in daily life and bathroom facilities, and their user experience directly affects user comfort. However, in actual use, overhead showers or faucets often leave residual water dripping after being turned off, which can last for several minutes or even hours. This residual water is usually cold and dripping onto the user can easily cause discomfort; if it drips onto hair or clothing, it can also lead to user complaints. To solve this problem, various water-stopping solutions have been proposed in existing technologies, but these solutions generally have certain limitations. For example, existing water-stopping technologies exhibit poor stability, high manufacturing costs, low yield rates, and high processing difficulty during mass production, which limits their widespread application. In addition, achieving rapid water-stopping also faces technical challenges: under low pressure conditions, the water-stopping structure is difficult to fully open to ensure smooth water flow; and after the water flow is turned off, it is difficult to quickly achieve a complete seal, resulting in poor water-stopping effect. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a water outlet device that can quickly stop water flow.

[0004] This utility model is achieved through the following technical solution:

[0005] A water outlet device capable of quickly stopping water flow includes a main body with a water inlet channel. The main body is equipped with a water outlet screen and a water outlet cavity. A water outlet nozzle, communicating with the water outlet cavity, is arranged on the water outlet screen. Water from the water inlet channel can be ejected through the water outlet nozzle. The device also includes a floating plate disposed within the water outlet cavity. A water-stopping swing shaft is disposed on the floating plate. The upper end of the swing shaft is configured to be movably connected to the floating plate via a universal structure, and the lower end of the swing shaft is configured to be inserted into the water outlet nozzle. Furthermore, an elastic element is included, configured to lift the floating plate so that the water-stopping swing shaft blocks the water outlet nozzle. When water flows through the water inlet channel, the water flow overcomes the force of the elastic element and drives the floating plate to move within the water outlet cavity, causing the water-stopping swing shaft to move within the water outlet nozzle, thus connecting the water outlet nozzle and allowing water to be ejected from it.

[0006] In this embodiment of the utility model, a spherical joint is provided at the upper end of the water-stopping swing shaft, and a connecting hole is provided on the floating plate. The spherical joint is configured to be able to connect with the connecting hole, and a gap is also formed between the water-stopping swing shaft and the connecting hole so that the water-stopping swing shaft can swing relative to the floating plate.

[0007] In this embodiment of the present invention, a convex ring is also provided on the outer periphery of the water-stopping swing shaft. The upper end face of the convex ring is configured to be located at the lower end of the connecting hole. The upper end face of the convex ring is configured to abut against the lower end face of the floating plate on the periphery of the connecting ring, so that the water-stopping swing shaft can move synchronously with the floating plate in the water passage cavity.

[0008] In this embodiment of the utility model, the upper end of the connecting hole is provided with a buckle, which is configured to cooperate with the ball joint so that the water-stopping swing shaft can move synchronously with the floating plate in the water passage cavity.

[0009] In this embodiment of the utility model, the water outlet is configured to have a water passage cavity in the middle, and the water inlet end of the water outlet is also configured to have a water inlet. The lower end of the water-stopping swing shaft is configured to block the water inlet. The water passage area of ​​the water passage cavity is larger than the water passage area of ​​the water inlet.

[0010] In this embodiment of the utility model, the water outlet is further provided with a guide surface, which is configured to be located between the water passage cavity and the water inlet, so as to guide the lower end of the water-stopping swing shaft from the water passage cavity to the water inlet.

[0011] In this embodiment of the utility model, a sealing ring is provided on the lower outer periphery of the water-stopping swing shaft. The sealing ring is configured to be able to seal the water inlet so as to block the water inlet.

[0012] In this embodiment of the utility model, the lower end of the water-stopping swing shaft is provided with a spherical sealing surface, which is configured to be able to seal with the water inlet so as to block the water inlet.

[0013] In this embodiment of the invention, the main body is further provided with a water outlet, which is located between the water inlet channel and the water outlet cavity. The water flowing into the water inlet channel flows through the water outlet to the water outlet cavity. The floating plate is provided with a connecting ring that can be adapted to the water outlet. When the water outlet device is in a water-stopped state, the connecting ring can be located inside the water outlet, and the water-stopping swing shaft blocks the water outlet. When the water outlet device is in a water-flowing state, the water flowing into the water inlet channel can act on the floating plate inside the connecting ring. After overcoming the force of the elastic element, the floating plate is driven to move downward, causing the water outlet to open and eject the water.

[0014] In this embodiment of the utility model, a guide hole is provided in the water outlet cavity, and a guide post is provided on the floating plate. The guide post is configured to be inserted into the guide hole to realize the guiding movement of the floating plate in the water outlet cavity; the elastic element is a spring, and the spring is located on the outer periphery of the guide hole and / or the guide post.

[0015] This utility model discloses a water outlet device capable of rapid water shut-off, which has the following beneficial effects: Through the linkage design of the floating plate and the water-stopping swing shaft, water flow can be quickly stopped when shut off, effectively preventing water droplet residue even at inclined angles, thus reducing the product's dimensional accuracy requirements. The overall structure is compact, with minimal increase in thickness, facilitating manufacturing and assembly, ensuring high mass production stability, and reducing cost. The design of the water outlet allows for flexible arrangement of the water outlet points to meet the needs of different application scenarios.

[0016] In particular, the hinged connection design between the water-stopping pivot and the floating plate solves the sealing failure problem caused by misalignment in traditional water-stopping structures. The water outlet's water passage cavity design balances the needs for rapid water stopping and efficient water discharge, significantly improving the device's performance.

[0017] In summary, this utility model provides a simple and reliable rapid water-stopping and water-discharging device, which solves the problems of incomplete water-stopping and high manufacturing difficulty in the prior art, and has significant technical advantages and market application prospects.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] Referring to the attached drawings in the instruction manual, a water outlet device capable of quickly stopping water flow is characterized by the coordinated operation of components such as a floating plate 6, a water-stopping swing shaft 7, an elastic element 8, and a water outlet 5, which enables the rapid water-stopping function when the water flow is closed.

[0033] The main body 1 is the core load-bearing structure of the entire device, and it has an inlet channel 2 and an outlet chamber 3 inside. The inlet channel 2 serves as the water inlet, guiding external water into the device, while the outlet chamber 3 accommodates the floating plate 6 and the linked water-stopping swing shaft 7. A water outlet net 4 is located at the bottom of the outlet chamber 3, and multiple water outlets 5 are configured on the water outlet net 4. Each water outlet 5 has a water passage cavity 16 in its center, the cross-sectional area of ​​which is larger than the cross-sectional area of ​​the inlet 17. Preferably, the water passage area of ​​this water passage cavity is larger than any other part of the outlet. This design not only reduces water flow resistance but also improves water flow efficiency. The guide surface 19 inside the outlet 5 is located between the water passage cavity 16 and the inlet 17, guiding the lower end of the water-stopping swing shaft 7 smoothly from the water passage cavity 16 to the inlet 17, thereby reducing frictional resistance and improving the device's response speed. Furthermore, during use, the diameter of the inlet gradually increases according to the direction of water flow. This ensures, under the action of the elastic element, that the lower end of the water-stopping swing shaft can effectively block the inlet of the outlet, thus achieving the purpose of water stoppage.

[0034] The floating plate 6 is located inside the water outlet chamber 3. Its main function is to control the opening and closing of the water outlet nozzles by moving the water-stopping swing shaft 7 up and down. Multiple water-stopping swing shafts 7 are installed on the floating plate 6, with the number of these shafts corresponding one-to-one with the number of water outlet nozzles 5. The upper end of the water-stopping swing shaft 7 is movably connected to the connecting hole 14 on the floating plate 6 via a ball joint 13. A gap 22 is formed between the water-stopping swing shaft 7 (which can be a non-ball joint portion) and the connecting hole 14, allowing the water-stopping swing shaft 7 to swing at a certain angle relative to the floating plate 6 (lateral swing). This universal structure design can adapt to water flow impacts at different angles, ensuring that the water-stopping swing shaft 7 always maintains a good sealing fit with the water outlet nozzle 5, while also eliminating misalignment (misalignment) between the water-stopping swing shaft and the water outlet nozzle.

[0035] Furthermore, the synchronous movement of the water-stopping swing shaft and the floating plate can be achieved in two embodiments: First, a convex ring 15 is provided on the outer periphery of the water-stopping swing shaft 7, and the upper end face of the convex ring 15 is in close contact with the lower end face of the floating plate 6, so that the water-stopping swing shaft 7 and the floating plate 6 can move synchronously within the water passage cavity 16. When the floating plate 6 is impacted by the water flow and moves downward, the water-stopping swing shaft 7 disengages from the inlet 17, and the water flow is ejected through the water passage cavity 16; when the water flow stops, the floating plate 6 moves upward under the action of the elastic element 8, causing the water-stopping swing shaft 7 to re-fit against the inlet 17, thereby achieving rapid water stoppage. Please refer to the attached drawings in the instruction manual. Figure 4 Secondly, the upper end of the connecting hole is equipped with a buckle 20, which is configured to cooperate with the ball joint and restrict the ball joint within the connecting hole, so that the water-stopping swing shaft can move synchronously with the floating plate in the water passage cavity. Please refer to the attached drawings in the instruction manual. Figure 5 .

[0036] The elastic element 8 is typically a spring, with one end abutting against the body at the bottom of the water outlet cavity 3 and the other end contacting the floating plate 6. The main function of the elastic element 8 is to provide an upward restoring force to the floating plate 6, blocking the inlet of the water outlet when the floating plate is not subjected to water flow force (water pressure), thus achieving water stoppage. When the water flow pressure in the water inlet channel 2 overcomes the force of the elastic element 8, the floating plate 6 moves downward, and the water-stopping swing shaft 7 disengages from the inlet 17, opening the inlet and allowing water to flow out through the water passage cavity 16. When the water flow is stopped, the elastic element 8 quickly returns to its original state, pushing the floating plate 6 upward, causing the water-stopping swing shaft 7 to re-adhere to the inlet 17, completing the rapid water-stopping process. To further improve the stability of the floating plate 6, a guide hole 11 is also provided in the water outlet cavity 3. This guide hole can be located on the upper surface of the water outlet mesh, and a guide post 12 is provided at a corresponding position on the floating plate 6. The guide post 12 is inserted into the guide hole 11 to ensure that the floating plate 6 remains stable during its up-and-down movement, preventing deviation. Meanwhile, the elastic element 8 is disposed on the outer periphery of the guide hole 11 and the guide post 12 to provide uniform elastic support force.

[0037] The water inlet 9 is located inside the main body 1, connecting the inlet channel 2 and the outlet chamber 3. The design of the water inlet 9 allows water to flow smoothly from the inlet channel 2 into the outlet chamber 3. A connecting ring 10, adapted to the water inlet 9, is provided on the floating plate 6. When the device is in a stopped state, the connecting ring 10 is located inside the water inlet 9, preventing residual water from entering the outlet chamber 3. When the device is in a flowing state, the water flow overcomes the force of the elastic element 8, driving the floating plate 6 downwards, disengaging the connecting ring 10 from the water inlet 9, allowing the water to enter the outlet chamber 3 and be ejected through the outlet nozzle 5. This design not only simplifies the structure of the device but also improves the accuracy of water flow control.

[0038] Meanwhile, multiple through holes can be distributed on the floating plate, connecting its upper and lower parts. Water can enter the water outlet chamber and then flow directly through the through holes to the water inlet of the water outlet panel, which is the water inlet of the water outlet, thus achieving rapid feedback of water output.

[0039] There are two ways to block the inlet of the water outlet: First, a sealing ring 18 or a spherical sealing surface 21 is fitted around the lower outer circumference of the water-stopping pivot 7 to form a tight seal with the inlet 17. The sealing ring 18 or the spherical sealing surface 21 effectively prevents water leakage from the inlet 17 when closed, ensuring reliable water-stopping performance. Furthermore, the water-stopping pivot 7 has a large range of movement within the water passage cavity 16, while the inlet 17 is relatively small. This design balances the needs for rapid water-stopping and efficient water output. When the water-stopping pivot 7 is completely detached from the inlet 17, water flows out through the water passage cavity 16. Sufficient space exists between the outlet cavity and the lower end of the water-stopping pivot for water flow, resulting in a stable water output. When the water-stopping pivot 7 re-fits the inlet 17, the water flow is quickly cut off, preventing the formation of residual water droplets.

[0040] In practical applications, the rapid water-stopping and water-discharging device of this invention can be widely used in bathroom fixtures such as overhead showers or head showers. For example, when a user uses the head shower and turns on the water supply, the water flows into the device through the inlet channel 2, passes through the outlet 9, and flows into the outlet chamber 3. At this time, the pressure of the water flow overcomes the force of the elastic element 8, pushing the floating plate 6 downward. The movement of the floating plate 6 causes the water-stopping swing shaft 7 to disengage from the inlet 17, and the water flow is ejected through the outlet chamber 16, forming a stable spray effect. When the user turns off the water supply, the water pressure disappears, the elastic element 8 quickly returns to its original state, and pushes the floating plate 6 upward. The movement of the floating plate 6 causes the water-stopping swing shaft 7 to re-fit against the inlet 17, achieving rapid water-stopping. Even at an inclined angle, the universal joint design between the water-stopping swing shaft 7 and the floating plate 6 ensures that the device always maintains good sealing performance and avoids water droplet residue.

[0041] This invention solves the problems of difficulty in fully opening the water-stopping structure under low pressure and achieving rapid sealing after water is shut off in existing technologies by optimizing the design of the water-stopping structure. The linkage design between the floating plate 6 and the water-stopping swing shaft 7 enables the device to quickly stop water flow when the water is turned off. The overall structure is compact, easy to manufacture, has high mass production stability, and is low in cost. The design of the water outlet 5 allows for flexible arrangement of the water outlet points to meet the needs of different application scenarios. The design of the guide surface 19 reduces the frictional resistance of the water-stopping swing shaft 7 during movement, further improving the response speed and service life of the device. In summary, this invention provides a simple, reliable, and rapid water-stopping device with significant technical advantages and promising market application prospects.
