[0023] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0025] In addition, the terms "first", "second", etc. are only used to distinguish descriptions and should not be understood as specific or special structures. The descriptions of the terms "some embodiments", "other embodiments", etc. mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this application, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine the different embodiments or examples described in this application and the features of the different embodiments or examples, unless they are contradictory.

[0026] In bathroom facilities, the water outlet is a common component. It's typically located within the shower room and connected to the plumbing. During use, the outlet disperses the water flow in the plumbing, creating a more even flow and making the shower more comfortable. The outlet typically includes a nozzle. When the user closes the plumbing connected to the outlet, a certain amount of residual water remains in the nozzle and external plumbing. Under the influence of gravity, water slowly flows out of the nozzle after the plumbing is closed, reducing the user experience.

[0027] Please also refer to Figure 1 and Figure 2 , an embodiment of the present application provides a water outlet device 1000, including a nozzle 100, a connecting portion 300 and a shut-off device 200. As an embodiment, the water outlet device 1000 can be a hand-held shower. In some other embodiments, the water outlet device 1000 can also be a top shower, which is not limited here. The nozzle 100 is formed with a water outlet chamber 110. The nozzle 100 is assembled on the connecting portion 300 and forms a receiving chamber 400 with the connecting portion 300. The shut-off device 200 is arranged in the receiving chamber 400 and selectively connects or separates the water outlet chamber 110 and the receiving chamber 400. The shut-off device 200 is provided with a water absorption chamber 210, which is connected to the water outlet chamber 110. When the shut-off device 200 separates the water outlet chamber 110 and the receiving chamber 400, the water absorption chamber 210 forms a negative pressure to absorb the residual water in the water outlet chamber 110.

[0028] The water outlet device 1000 can be connected to a hose so that the user can move the position of the water outlet device 1000 at will, which is more convenient during the shower process. The water outlet device 1000 can also be connected to a hard water pipe and set on the top of the shower room. However, there is a problem that the water outlet direction of the water outlet device 1000 cannot be adjusted when the water outlet device 1000 is directly connected to the hard water pipe. Therefore, in some embodiments, the water outlet device 1000 also includes a connector 500 and a ball head 600. The ball head 600 extends into the accommodating cavity 400, and the connector 500 connects the ball head 600 to the connecting part 300. A water inlet pipe 610 can be provided in the ball head 600. The water inlet pipe 610 is connected to the accommodating cavity 400 and is used to connect to an external pipe. As an embodiment, please refer to Figure 3The connector 500 can be assembled onto the connecting portion 300 using threads, making it easy to assemble and disassemble. The connector 500 has a mounting hole 510, and the larger radius portion of the ball head 600 can be inserted into the mounting hole 510, so that the ball head 600 can be connected to the connecting portion 300. At the same time, the ball head 600 and the connecting portion 300 can be rotated within any angle, so that the direction of the water outlet device 1000 can be adjusted. The external pipe is connected to the ball head 600, and the pipe is connected to the water inlet pipe 610 inside the ball head 600. The external pipe supplies water to the water outlet device 1000 through the ball head 600 and the water inlet pipe 610.

[0029] The spray head 100 is used to evenly disperse the water flow to improve the comfort of the user. Figure 1 and Figure 2 In this embodiment, the nozzle 100 is formed with a plurality of water outlet holes 120 connected to the water outlet cavity 110. In other embodiments, the nozzle 100 can also be a nozzle 100 with the function of atomizing water flow, which is not limited here. The water flows through the accommodating cavity 400 and flows out after passing through the water outlet cavity 110. As an embodiment, the water outlet cavity 110 can be provided with a plurality of holes, please refer to Figure 4 By providing multiple water outlet chambers 110, the amount of residual water that can be accommodated in each water outlet chamber 110 can be reduced. When negative pressure is formed in the water absorption chamber 210, the smaller amount of residual water in the water outlet chamber 110 facilitates the water absorption chamber 210 to quickly absorb the residual water in the water outlet chamber 110. In this embodiment, the water outlet chamber 110 includes a first water outlet chamber 111 and multiple second water outlet chambers 112. The multiple second water outlet chambers 112 are arranged around the first water outlet chamber 111 and are connected to the first water outlet chamber 111. The first water outlet chamber 111 and the second water outlet chamber 112 are both connected to multiple water outlet holes 120. The protrusion 142 is provided on the side of the cover 140 facing the connecting portion 300 and is located within the accommodating chamber 400. This design makes the sprayed water flow more dispersed and beautiful.

[0030] During the manufacturing process of the nozzle 100, since the water outlet cavity 110 is set inside the nozzle 100, there is a problem that it cannot be integrally formed during the manufacturing process. As an implementation method, please participate again Figure 1 and Figure 2The showerhead 100 includes a mounting portion 130 and a cover 140. The mounting portion 130 and the connecting portion 300 together form a receiving chamber 400. The cover 140 is connected to the end of the mounting portion 130 away from the connecting portion 300, and a water outlet chamber 110 is formed within the cover 140. During the manufacturing process of the showerhead 100, a recess can be provided on the mounting portion 130, and the cover 140 can seal the recess to form the water outlet chamber 110. In one embodiment, the portion of the cover 140 opposite the recess can be provided with multiple water outlet holes 120, so that the water outlet holes 120 communicate with the water outlet chamber 110. The cover 140 and the mounting portion 130 can be fixedly connected using bolts. In other embodiments, the cover 140 and the mounting portion 130 can also be fixedly connected using glue or other methods, which are not limited here. In one embodiment, a water channel is formed on the mounting portion 130 to connect the water outlet chamber 110 and the water intake chamber 210.

[0031] In order to solve the problem that after the external pipeline is closed, the residual water in the water outlet chamber 110 and part of the external pipeline will flow out from the water outlet hole 120 under the action of gravity, the water outlet device 1000 provided in the present application includes a cut-off device 200. The cut-off device 200 is provided with a water absorption chamber 210, which is connected to the water outlet chamber 110. When the cut-off device 200 separates the water outlet chamber 110 from the accommodating chamber 400, the water absorption chamber 210 forms a negative pressure to absorb the residual water in the water outlet chamber 110. As an embodiment, the water absorption chamber 210 can be connected to the water outlet chamber 110 through a water channel, so that the residual water in the water outlet chamber 110 can be sucked into the water absorption chamber 210 through the water channel. In other embodiments, the water absorption chamber 210 and the water outlet chamber 110 can also be connected by a connecting member 500 such as a connecting tube, which is not limited here.

[0032] In order to solve the problem that the residual water in the external pipe flows into the water outlet cavity 110 under the action of gravity and then flows out from the water outlet 120, in some embodiments, please refer to Figure 1 and Figure 6 The intercepting device 200 may include a movable part 220 and an elastic part 230 for resetting the movable part 220. The movable part 220 is slidably arranged in the accommodating chamber 400. When the water flow in the external pipe hits the movable part 220, the movable part 220 can connect the water outlet chamber 110 and the accommodating chamber 400. When the user closes the external pipe, the water flow stops hitting the movable part 220. At this time, the movable part 220 can be reset under the drive of the elastic part 230 to separate the accommodating chamber 400 and the water outlet chamber 110. As an embodiment, the elastic part 230 can be arranged between the movable part 220 and the nozzle 100. Please refer to Figure 5The movable part 220 has a sealing surface 211. When the water flow hits the movable part 220, the elastic part 230 is compressed, so as to push the movable part 220 to move away from the nozzle 100 after the user closes the external water pipe. At this time, the sealing surface 211 can abut the mounting portion 130 to separate the accommodating chamber 400 from the water absorption chamber 210. In other embodiments, the elastic part 230 can also be arranged on the side of the movable part 220 away from the nozzle 100. When the water flow hits the movable part 220, the movable part 220 causes the elastic part 230 to stretch to separate the accommodating chamber 400 from the water outlet chamber 110.

[0033] Since the movable part 220 needs to push or stretch the elastic part 230 under the impact of the water flow, the material of the movable part 220 should be made of a hard material. However, the movable part 220 made of hard material has the problem of poor sealing. Therefore, in some embodiments, the sealing surface 211 of the movable part 220 can be the side wall of the movable part 220, and the mounting portion 130 includes an inner wall 131 located in the accommodating chamber 400. The outer contour of the inner wall 131 is roughly the same as the shape of the movable part 220, so that the movable part 220 can slide along the inner wall 131. A sealing portion is provided on the inner wall 131 along the side of the movable part 220. The sealing portion is provided around the inner wall 131, and its outer contour can be smaller than the outer contour of the movable part 220. In this way, when the movable part 220 is driven by the elastic part 230, the sealing surface 211 can abut against the sealing portion, so that the water outlet chamber 110 is separated from the accommodating chamber 400. In order to enhance the effect of dividing the water outlet cavity 110 and the accommodating cavity 400, a sealing ring 212 can be further provided on the sealing surface 211. The sealing ring 212 can be a flexible sealing ring 212 made of rubber. The sealing ring 212 is provided between the sealing surface 211 and the inner wall 131.

[0034] In some embodiments, when the movable member 220 slides, the sealing ring 212 can abut against the sealing portion on the inner wall 131 to separate the accommodating chamber 400 and the water outlet chamber 110, or separate from the sealing portion on the inner wall 131 to connect the accommodating chamber 400 and the water outlet chamber 110. The elastic sealing ring 212 can fit more closely to the sealing portion and the sealing surface 211, thereby achieving a better sealing effect.

[0035] In other embodiments, the inner diameter of the portion of the inner wall 131 near the cover 140 is larger than the outer diameter of the sealing ring 212. A communication hole 1311 is defined in the inner wall 131 near the cover 140. Communication hole 1311 connects the accommodating chamber 400 and the water outlet chamber 110. An elastic member 230 is disposed between the cover 140 and the movable member 220. The movable member 220 can be disposed within communication hole 1311 and pushed by the elastic member 230. Because the inner diameter of the portion of the inner wall 131 near the cover 140 is larger than the outer diameter of the sealing ring 212, when the movable member 220 is located within this portion of communication hole 1311, the sealing ring 212 cannot abut against the inner wall 131, thereby allowing communication between the water outlet chamber 110 and the accommodating chamber 400. When the movable member 220 moves to a certain extent, the inner diameter of the communication hole 1311 is smaller than the outer diameter of the sealing ring 212 , so that the sealing ring 212 abuts against the inner wall 131 , separating the accommodating chamber 400 from the water outlet chamber 110 .

[0036] There may be multiple movable parts 220. In some embodiments, the intercepting device 200 further includes a connecting part 240. Figure 1 Multiple movable members 220 are disposed at one end of a connecting member 240, and an elastic member 230 is disposed between the connecting member 240 and the nozzle, enabling the multiple movable members 220 to move synchronously. In one embodiment, the continuous water flow can impact the connecting member 240, driving the movable members 220 to connect the water outlet chamber 110 with the accommodating chamber 400. The elastic member 230 can be used to drive the connecting member 240 to reset, allowing the connecting member 240 to drive the movable members 220 to separate the accommodating chamber 400 from the water outlet chamber 110.

[0037] During the movement of the movable member 220, the movable member 220 is driven only by the elastic member 230, and there is a problem that the movement direction may sometimes be offset. Therefore, in some embodiments, the side of the cover 140 facing the connecting portion 300 may be provided with a guide hole 141. Please refer to Figure 5 One end of the elastic member 230 extends into the guide hole 141 and abuts the cover 140, while the other end abuts the movable member 220. The diameter of the guide hole 141 can be substantially equal to the diameter of the elastic member 230. In this way, during the movement of the elastic member 230, the elastic member 230 only moves within the guide hole 141, and the elastic member 230 is not easily deflected, so that the movement trajectory of the movable member 220 is also not easily deflected.

[0038] The movable part 220 can only ensure that the residual water in the accommodating chamber 400 will not flow out under the action of gravity. However, the residual water in the water outlet chamber 110 still has the problem of flowing out when only the movable part 220 is set, so a water absorption chamber 210 is set in the intercepting device 200.

[0039] As an embodiment, the water absorption chamber 210 can be disposed on the movable member 220. During the resetting process, the movable member 220 can cause the water absorption chamber 210 to absorb the residual water in the water outlet chamber 110. In other embodiments, the water absorption chamber 210 can also be a structure relatively independent of the movable member 220 and driven by a drive structure different from the elastic member 230, such as a solenoid valve, etc., which is not limited here. In this embodiment, the volume of the water absorption chamber 210 increases or decreases with the movement of the movable member 220. When the movable member 220 separates the water outlet chamber 110 from the accommodating chamber 400, the volume of the water absorption chamber 210 is at its maximum state. Moreover, as the volume of the water absorption chamber 210 expands to its maximum state, a negative pressure is formed in the water absorption chamber 210, thereby sucking in the residual water in the water outlet chamber 110. If the residual water in the water absorption chamber 210 is too large, it may also flow out under the action of gravity. Therefore, in some embodiments, multiple water absorption chambers 210 may be provided, each containing a small amount of residual water. The multiple water outlet chambers 110 are not interconnected, and each water absorption chamber 210 is only connected to one water outlet chamber 110. Compared to a case where the multiple water outlet chambers 110 are not interconnected, if the multiple water outlet chambers 110 are interconnected, the negative pressure generated by the water absorption chambers 210 is less effective, and the residual water in the water outlet chambers 110 cannot be effectively drawn into the water absorption chambers 210. As an embodiment, the volume of the water outlet chamber 110 may be less than or equal to the volume of the water absorption chamber 210, so that the water absorption chamber 210 can completely absorb the residual water in the water outlet chamber 110. Furthermore, due to the tension of the water itself, the small amount of residual water is not easily discharged from the water absorption chamber 210.

[0040] As an embodiment, the water absorption chamber 210 may have an opening 2101. At the same time, at least one protrusion 142 is provided on the side of the nozzle 100 facing the movable member 220. The protrusion 142 is at least partially embedded in the water absorption chamber 210 along the opening 2101. When the elastic member 230 resets the movable member 220 away from the protrusion 142, the water absorption chamber 210 slides relative to the protrusion 142, generating a negative pressure in the water absorption chamber 210 and drawing in residual water from the water outlet chamber 110. This design allows the movement of the movable member 220 to drive the water absorption chamber 210 to absorb water, resulting in a simpler structure and a smaller volume for the interception device 200.

[0041] In order to allow the residual water to flow from the water outlet chamber 110 to the water absorption chamber 210, the water outlet chamber 110 and the water absorption chamber 210 need to be connected. However, a channel with a large cross-section will result in the residual water being unable to be accommodated in the water absorption chamber 210 for a long time, and there is also the problem that the residual water in the water absorption chamber 210 flows out under the action of gravity. Therefore, in some embodiments, please refer to Figure 4The protrusion 142 is provided with a water suction channel 1421, which connects the water suction chamber 210 with the water outlet chamber 110. It is convenient to process the water suction channel 1421 on the protrusion 142. Furthermore, the small cross-section of the water suction channel 1421 prevents residual water in the water outlet chamber 110 from naturally flowing out. In other embodiments, the protrusion 142 may also be provided with a hole extending through the protrusion 142, thereby also connecting the water outlet chamber 110 with the water suction chamber 210.

[0042] The operating principle of the water outlet device 1000 provided in the embodiment of the present application is as follows:

[0043] The water outlet device 1000 provided herein has a flow-blocking device 200 disposed within the accommodating chamber 400 formed between the nozzle 100 and the connecting portion 300. The flow-blocking device 200 includes a connecting member 240, a movable member 220, and an elastic member 230. A water absorption chamber 210 is also formed on the movable member 220. When a user opens the water pipe connected to the water outlet device 1000, the connecting member 240, under the impact of the water flow, compresses the elastic member 230 and simultaneously drives the multiple movable members 220 to connect the accommodating chamber 400 with the water outlet chamber 110, allowing water to be ejected through the water outlet hole 120. When the user turns off the water pipe, the connecting member 240 is driven by the elastic member 230 to reset, and at the same time, the movable member 220 is driven to form a negative pressure in the water absorption chamber 210, and the residual water in the water outlet chamber 110 is sucked in through the water absorption channel 1421 formed on the protrusion 142, so as to prevent the water in the water outlet chamber 110 and part of the water pipe from flowing out under the action of gravity after the external water pipe is turned off, and wetting the user who has just finished bathing. The water outlet device 1000 provided in the present application can timely separate the water outlet chamber 110 from the accommodating chamber 400 through the intercepting device 200 after the external water pipe stops supplying water, so that the residual water in the accommodating chamber 400 and the external water pipe connected to the accommodating chamber 400 cannot flow out. At the same time, the intercepting device 200 is provided with a water absorption chamber 210, which can absorb the residual water in the water outlet chamber 110, thereby preventing the residual water in the water outlet chamber 110 from flowing out, and providing a better user experience.

[0044] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included in the scope of protection of the present application.
