[0011] Preferably, the flow area of ​​the inlet is smaller than that of the outlet.

[0012] Preferably, the support blocks are located in the water outlet guide channel, and multiple support blocks are provided, with the multiple support blocks evenly distributed around the outer periphery of the water outlet guide port; or...

[0013] The support block is ring-shaped and is arranged around the outer periphery of the water outlet.

[0016] Preferably, the outer wall of the water inlet shell is provided with a water inlet ring platform, which surrounds and forms the water inlet guide groove. The outer wall of the water outlet shell is provided with a water outlet ring platform, which surrounds and forms the water outlet guide groove. The water outlet ring platform is arranged around the outside of the water inlet ring platform.

[0017] Preferably, the water-stopping component includes an interconnected middle portion and an outer ring portion, with the water-stopping diaphragm disposed in the middle portion and the outer ring portion sandwiched between the bottom of the inlet ring platform and the outlet guide groove.

[0018] Preferably, a limiting ring groove is provided on one side of the outer ring portion around the middle portion, and the water inlet ring platform abuts against the bottom of the limiting ring groove.

[0019] Preferably, the water inlet chamber includes:

[0020] The water inlet intermediate cavity is connected to the water inlet;

[0021] Multiple water inlet branch channels are distributed on the outer periphery of the water inlet intermediate cavity and are respectively connected to the water inlet intermediate cavity;

[0022] Multiple water inlet sub-cavities are provided, each connected to the intermediate water inlet cavity or the water inlet branch channel.

[0027] The beneficial effects of this utility model are:

[0028] By setting a water-stop diaphragm, when the diaphragm elastically deforms towards the outlet chamber, it connects the inlet and outlet chambers, allowing water to flow out immediately. Furthermore, by setting a support block, when the water flow in the inlet chamber stops, the water-stop diaphragm elastically resets and, with the support block's resistance, quickly blocks the connection between the inlet and outlet chambers. At this time, the supporting force of the support block, combined with the elastic force of the water-stop diaphragm, causes the diaphragm to quickly recover, ensuring it remains safely and reliably in the water-stop position, immediately stopping the water flow. This reduces the possibility of leakage after prolonged use and effectively improves the water-stopping effect. Moreover, due to the presence of the support block, when the water outlet device is tilted, the support block's support on the water-stop diaphragm prevents the water in the outlet device from opening the diaphragm due to its own weight, resulting in a better immediate shut-off effect when the outlet device is tilted.

[0061] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0062] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0063] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. 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.

[0064] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0065] like Figures 1 to 15As shown, this utility model provides a water outlet device, including a housing 1 and a water-stopping component 2. The outer casing 1 is provided with an inlet chamber 100 and an outlet chamber 200. The inlet chamber 100 is connected to the outside through an inlet 101, and the outlet chamber 200 is connected to the outside through an outlet 201. The inlet chamber 100 and the outlet chamber 200 are connected by a connecting chamber 300. A support block 123 is provided in the connecting chamber 300. A water-stopping element 2 is provided in the connecting chamber 300. A water-stopping diaphragm 212 is provided on the water-stopping element 2. The water flow in the inlet chamber 100 can impact the water-stopping diaphragm 212 and cause it to elastically deform toward the outlet chamber 200. When the water-stopping diaphragm 212 elastically deforms toward the outlet chamber 200, it connects the inlet chamber 100 and the outlet chamber 200. When the water flow in the inlet chamber 100 stops, the water-stopping diaphragm 212 elastically resets and blocks the connection between the inlet chamber 100 and the outlet chamber 200 under the support of the support block 123.

[0066] In this invention, by providing a water-stopping diaphragm 212, when the water-stopping diaphragm 212 elastically deforms toward the water outlet cavity 200, it connects the water inlet cavity 100 and the water outlet cavity 200, allowing water to flow out immediately. Furthermore, by providing a support block 123, when the water flow in the water inlet cavity 100 stops, the water-stopping diaphragm 212 elastically resets and, under the support of the support block 123, quickly blocks the connection between the water inlet cavity 100 and the water outlet cavity 200. At this time, the supporting force of the support block 123, combined with the elastic force of the water-stopping diaphragm 212, prevents the water-stopping diaphragm from flowing out. The rapid response of 212 ensures that the water-stop diaphragm 212 can be safely and reliably maintained in the water-stopping position, stopping the water supply immediately. This reduces the possibility of leakage after prolonged use of the water-stop diaphragm 212 and effectively improves its water-stopping effect. Furthermore, due to the presence of the support block 123, when the water outlet device is tilted, the support block 123 supports the water-stop diaphragm 212, preventing the water in the water outlet device from opening the water-stop diaphragm 212 by its own weight. This results in a better immediate shut-off effect when the water outlet device is tilted.

[0067] In this embodiment, the water outlet device is a shower head. The support block 123 abuts against the side of the water-stopping diaphragm 212 facing the water outlet cavity 200. The water-stopping diaphragm 212 is made of an elastic material such as rubber, which is not limited here. It has a conducting position and a water-stopping position. When there is a conducting position, the water-stopping diaphragm 212 elastically deforms to conduct the water inlet cavity 100 and the water outlet cavity 200, so that the water entering from the water inlet 101 can flow out from the water outlet 201 through the water inlet cavity 100 and the water outlet cavity 200. When in the water-stopping position, the water-stopping diaphragm 212 resets and blocks the water inlet cavity 100 and the water outlet cavity 200, so that the water outlet device stops water immediately.

[0068] In other embodiments, the water outlet device may also be other bathroom spray devices, which are not limited here.

[0069] Specifically, the outer casing 1 includes an inlet casing 11 and an outlet casing 12. An inlet cavity 100 is disposed within the inlet casing 11, which has an inlet guide groove 111. The bottom of the inlet guide groove 111 has an inlet flow port 112 communicating with the inlet cavity 100. The outlet casing 12 is connected to the inlet casing 11, and an outlet cavity 200 is disposed within the outlet casing 12. The outlet casing 12 has an outlet guide groove 121, which has an outlet flow port 122 communicating with the outlet cavity 200. The inlet guide groove 111 and the outlet guide groove 121 are assembled to form a connecting cavity 300. The above configuration allows the water-stopping component 2 to be installed on the outside between the water inlet housing 11 and the water outlet housing 12, which facilitates the disassembly and maintenance of the water-stopping component 2. Furthermore, the water-stopping component 2 is positioned and installed in the connecting cavity 300 formed by the water inlet guide channel 111 and the water outlet guide channel 121, making it less prone to movement and displacement, thus ensuring greater safety and reliability.

[0070] More specifically, such as Figure 5 As shown, the flow area of ​​the inlet 112 is smaller than that of the outlet 122. This arrangement allows the water flowing out of the inlet 112 to more reliably open the water-stop diaphragm 212.

[0071] In this embodiment, Figure 4 and Figure 5 The middle arrow indicates the direction of water flow. The inlet guide 112 and the outlet guide 122 are set coaxially and directly opposite each other.

[0072] In one embodiment, such as Figure 2 and Figure 3 As shown, the support block 123 is located in the water outlet guide channel 121, and multiple support blocks 123 are evenly distributed around the outer periphery of the water outlet guide port 122. The above arrangement, while ensuring smooth water flow, achieves support for the water-stopping diaphragm 212.

[0073] Specifically, in the above embodiment, multiple water-stopping membranes 212 are provided. The multiple water-stopping membranes 212 are evenly distributed around the axis of the water outlet 122. Along the circumference of the water outlet 122, two adjacent water-stopping membranes 212 correspond to a support block 123, and the support block 123 abuts against the junction of two adjacent water-stopping membranes 212.

[0074] More specifically, in the above embodiment, four water-stopping membranes 212 are provided, and four support blocks 123 are provided, with the four support blocks 123 respectively supporting the four junctions of the four water-stopping membranes 212.

[0075] In another embodiment, such as Figure 14 and Figure 15As shown, the support block 123 is ring-shaped and surrounds the outer periphery of the water outlet 122. This arrangement allows the support block 123 to more comprehensively support the water-stopping diaphragm 212.

[0076] In other embodiments, the support block 123 may also be of other structural form and connected to the bottom or wall of the water outlet guide channel 121, as long as it can provide support for the water-stopping diaphragm 212.

[0077] Specifically, the inlet housing 11 and the outlet housing 12 are provided with a first alignment member 13 and a second alignment member 14, respectively. When the inlet housing 11 and the outlet housing 12 are connected, the first alignment member 13 is engaged with the second alignment member 14, so that the inlet housing 11 and the outlet housing 12 can be accurately connected together.

[0078] More specifically, both the inlet housing 11 and the outlet housing 12 are disc-shaped. A first alignment member 13 and a second alignment member 14 are respectively provided on opposite radial sides of the inlet housing 11. A first alignment member 13 and a second alignment member 14 are respectively provided on opposite radial sides of the outlet housing 12. The first alignment member 13 on the inlet housing 11 is engaged with the second alignment member 14 on the outlet housing 12, and the second alignment member 14 on the inlet housing 11 is engaged with the first alignment member 13 on the outlet housing 12.

[0079] In this embodiment, fasteners such as bolts are inserted through the water inlet housing 11 and the water outlet housing 12 to fasten the water inlet housing 11 and the water outlet housing 12 together. The first alignment member 13 is provided with a locking protrusion, and the second alignment member 14 is provided with a locking groove. The locking protrusion is correspondingly locked in the locking groove.

[0080] Specifically, the water-stopping component 2 includes an interconnected intermediate portion 21 and an outer ring portion 22. A water-stopping membrane 212 is disposed in the intermediate portion 21, and the outer ring portion 22 is used to support the intermediate portion 21.

[0081] More specifically, the water-stopping component 2 is provided with a receiving groove 211, which covers the outside of the support block 123. The bottom of the receiving groove 211 is provided with a water passage hole 2111 communicating with the outside, and the water-stopping diaphragm 212 is disposed at the water passage hole 2111. By providing the receiving groove 211, the alignment of the water-stopping diaphragm 212 and the support block 123 is made more precise.

[0082] In this embodiment, the water-stopping component 2 is made of an elastic material such as rubber, which is not limited here. Four water-stopping membranes 212 are formed by opening a cross-shaped notch in the bottom of the receiving groove 211. The four water-stopping membranes 212 are evenly distributed around the axis of the water passage hole 2111. When the four water-stopping membranes 212 are in contact with each other, they are in a water-stopping position. The water passage hole 2111 is located between the water inlet guide port 112 and the water outlet guide port 122. The diameter of the water passage hole 2111 is larger than the diameter of the water inlet guide port 112. The water inlet guide port 112, the water passage hole 2111 and the water outlet guide port 122 are coaxially arranged so that the water flow can accurately impact the water-stopping membrane 212 at the water passage hole 2111.

[0083] Specifically, the outer wall of the inlet housing 11 is provided with an inlet ring platform 113, which surrounds and forms an inlet guide groove 111. The outer wall of the outlet housing 12 is provided with an outlet ring platform 124, which surrounds and forms an outlet guide groove 121. The outlet ring platform 124 is arranged around the outside of the inlet ring platform 113. The outlet ring platform 124 and the inlet ring platform 113 are interlocked to achieve the assembly of the connecting cavity 300, making the sealing of the connecting cavity 300 more reliable.

[0084] More specifically, the outer ring 22 is sandwiched between the inlet ring platform 113 and the bottom of the outlet guide groove 121. This arrangement allows the outer ring 22 of the water-stopping component 2 to function as a sealant, enabling the water-stopping component 2 to simultaneously seal the communicating cavity 300 during assembly, reducing the number of required parts and improving the assembly efficiency of the water outlet device.

[0085] In this embodiment, a limiting annular groove 221 is provided on one side of the outer ring portion 22 surrounding the middle portion 21, and the water inlet ring platform 113 abuts against the bottom of the limiting annular groove 221. The above arrangement allows the outer ring portion 22 and the middle portion 21 to cooperate in wrapping around the end of the water inlet ring platform 113, thereby improving the sealing effect.

[0086] Specifically, such as Figure 7 As shown, the water inlet chamber 100 includes an intermediate water inlet chamber 110, water inlet branch channels 120, and water inlet sub-chambers 130. The intermediate water inlet chamber 110 is connected to the water inlet 101. Multiple water inlet branch channels 120 are provided, distributed around the periphery of the intermediate water inlet chamber 110 and connected to it respectively. Multiple water inlet sub-chambers 130 are provided, connected to either the intermediate water inlet chamber 110 or the water inlet branch channels 120. Each of the multiple water inlet sub-chambers 130 is correspondingly equipped with multiple connecting chambers 300, and each water inlet sub-chamber 130 is connected to a connecting chamber 300 through a water inlet guide port 112. This arrangement allows the water flowing into the water inlet chamber 100 to be efficiently dispersed and distributed to the multiple connecting chambers 300.

[0087] More specifically, such as Figure 9As shown, the water outlet chamber 200 includes an intermediate water outlet chamber 210, a branch water outlet channel 220, and a sub-chamber water outlet 230. Multiple intermediate water outlet chambers 210 are provided, and each intermediate water outlet chamber 210 is correspondingly configured with multiple connecting chambers 300. Each intermediate water outlet chamber 210 is connected to a connecting chamber 300 via a water outlet guide port 122. At least one branch water outlet channel 220 is connected to the outer periphery of each intermediate water outlet chamber 210. Each sub-chamber water outlet 230 is connected to either an intermediate water outlet chamber 210 or a branch water outlet channel 220, and each sub-chamber water outlet 230 is connected to a water outlet 201. This configuration allows the water flowing into the water outlet chamber 200 to be efficiently dispersed to multiple water outlets 201.

[0088] In this embodiment, the water flowing in from the inlet 101 first enters the intermediate inlet cavity 110 of the inlet chamber 100, and then is dispersed to various parts of the inlet chamber 100 by multiple inlet branch channels 120. Finally, it enters the connecting cavity 300 through the inlet sub-cavity 130. The water flowing from the multiple connecting cavities 300 into the outlet chamber 200 first flows into multiple intermediate outlet cavities 210 for primary dispersion, and then flows from the intermediate outlet cavities 210 to the outlet branch channels 220 for secondary dispersion. Finally, it enters the outlet 201 through the outlet sub-cavity 230 and flows out of the water outlet device.

[0089] In this embodiment, as Figure 2 and Figure 4 As shown, the water outlet device also includes a nut cap 3, a wear-resistant ring 4, a ball head 5, and a sealing ring 6. The nut cap 3 is screwed onto the outer casing 1, and the ball head 5 is clamped between the nut cap 3 and the outer casing 1. One end of the ball head 5 extends out of the nut cap 3 to connect to an external water passage, and the other end connects to the water inlet 101. The wear-resistant ring 4 is clamped between the nut cap 3 and the ball head 5 to seal and prevent the ball head 5 from coming out of the nut cap 3. The sealing ring 6 is clamped between the ball head 5 and the outer casing 1 for sealing.

[0090] In this embodiment, the water outlet device is a shower head. Using the surface where the water outlet 201 is located as a reference, an experiment comparing this shower head with an existing shower head is conducted to check whether there is any dripping after the water flow is completed and the inlet valve is closed. Figure 16 As shown in the figure (the horizontal axis represents the tilt angle of the shower head, and the vertical axis represents the experimental results), the experimental comparison results shown in the figure are as follows: when the tilt angle is between 0° and 20°, the shower head of this embodiment can ensure that it does not drip water. When the tilt angle is between 0° and 6°, the existing shower head can ensure that it does not drip water, but when the tilt angle is greater than 6°, the existing shower head has a dripping phenomenon.

[0091] In this embodiment of the water outlet device, external water enters the outer casing 1 from the ball head 5, and then impacts the water-stopping diaphragm 212 of the water-stopping member 2 through the water inlet guide 112 on the outer casing 1, causing the water passage 2111 to open, thereby entering the water outlet chamber 200, and finally flowing out from the water outlet 201. Since the support block 123 in the connecting cavity 300 can hold the water-stopping diaphragm 212 in place and prevent it from easily deforming, and the support block 123 only has a circular notch at its center, only when the water flow has a certain velocity and impacts the notch on the water-stopping diaphragm 212 through the water inlet guide 112 on the outer casing 1 can the water-stopping diaphragm 212 be opened and enter the water outlet chamber 200. Figure 12 As shown, when the water flow stops, the water flowing from the outer casing 1 through the water inlet 112 no longer has impact force, and the cut on the water-stop diaphragm 212 automatically closes after losing its impact force, as... Figure 13 As shown, the water-stopping diaphragm 212 will prevent residual water from entering the water outlet chamber 200, thereby achieving immediate shut-off. The water-stopping diaphragm 212 and the support block 123 work together to realize the multi-angle immediate shut-off of the water outlet device, requiring fewer parts and lower cost.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
