The water outlet device 1000 may be in communication with a hose, so that a user may move the position of the water outlet device 1000 at will, so as to be more convenient in the shower process. The water outlet means 1000 may be connected to a hard water pipe and provided at the top of the shower stall. However, the problem that the water outlet direction of the water outlet device 1000 cannot be adjusted exists when the water outlet device 1000 is directly communicated with the hard water pipe, so in some embodiments, the water outlet device 1000 further comprises a connecting piece 500 and a ball 600. Ball 600 extends into receiving cavity 400, and connecting member 500 connects ball 600 to communicating portion 300.

The external pipe is connected with the ball 600, and the pipe is connected with the water inlet pipe 610 in the ball 600, and the external pipe supplies water into the water outlet device 1000 through the ball 600 and the water inlet pipe 610.

The spray head 100 serves to uniformly disperse the water flow to improve user comfort. Please refer to fig. 1 and fig. 2 again. In this embodiment, the nozzle 100 is formed with a plurality of outlet holes 120 communicating with the outlet chamber 110. In other embodiments, the nozzle 100 may be a nozzle 100 having a function of atomizing water, which is not limited herein. The water flows through the receiving chamber 400 and flows out after flowing through the water outlet chamber 110. As an embodiment, a plurality of outlet chambers 110 may be provided, referring to FIG. 4, by providing a plurality of outlet chambers 110, the amount of residual water in each outlet chamber 110 may be smaller, and when negative pressure is formed in water suction chamber 210, the smaller residual water in outlet chamber 110 is beneficial to make water suction chamber 210 suck the residual water in outlet chamber 110 quickly. In this embodiment, the outlet chamber 110 includes a first outlet chamber 111 and a plurality of second outlet chambers 112, the plurality of second outlet chambers 112 are disposed around the first outlet chamber 111 and are communicated with the first outlet chamber 111, the first outlet chamber 111 and the second outlet chamber 112 are both communicated with the plurality of outlet holes 120, and the protrusion 142 is disposed on a side of the cover 140 facing the communicating portion 300 and located in the accommodating chamber 400. Through the design, the sprayed water flow is more dispersed and beautiful.

In the manufacturing process of the spray head 100, the water outlet cavity 110 is disposed inside the spray head 100, so that the spray head cannot be integrally molded in the manufacturing process. In one embodiment, please refer to fig. 1 and 2 again, the nozzle 100 includes a mounting portion 130 and a surface cover 140, the mounting portion 130 and the communicating portion 300 enclose an accommodating chamber 400, the surface cover 140 is connected to one end of the mounting portion 130 away from the communicating portion 300, and the water outlet chamber 110 is formed in the surface cover 140. During manufacture of the spray head 100, a recess may be provided in the mounting portion 130 and the face cap 140 closes the recess to form the outlet chamber 110. As an embodiment, a portion of the face cover 140 opposite to the recess may be provided with a plurality of outlet holes 120, such that the outlet holes 120 are communicated with the outlet chamber 110. The surface cover 140 and the mounting portion 130 may be fixedly coupled by bolts. In other embodiments, the surface cover 140 and the mounting portion 130 may be fixedly connected by gluing or the like, which is not limited herein. In one embodiment, a water channel is formed on the mounting portion 130, and the water channel can communicate the water outlet chamber 110 with the water suction chamber 210.

In order to solve the problem that residual water in the water outlet cavity 110 and part of the external pipelines flows out from the water outlet hole 120 under the action of gravity after the external pipelines are closed, the water outlet device 1000 provided by the application comprises the cut-off device 200. The shutoff device 200 is provided with a water suction cavity 210, the water suction cavity 210 is communicated with the water outlet cavity 110, and when the shutoff device 200 separates the water outlet cavity 110 from the accommodating cavity 400, the water suction cavity 210 forms negative pressure to suck residual water in the water outlet cavity 110. As an embodiment, the water suction cavity 210 may communicate with the water outlet cavity 110 through a water channel, so that residual water in the water outlet cavity 110 can be sucked into the water suction cavity 210 through the water channel. In other embodiments, the water-absorbing chamber 210 and the water-outlet chamber 110 can also communicate by using a connecting piece 500 such as a connecting tubule, which is not limited herein.

In order to solve the problem that the residual water in the external pipe flows into the outlet chamber 110 and then flows out of the outlet hole 120 under the action of gravity, in some embodiments, referring to fig. 1 and 6, the stopping device 200 may include a movable member 220 and an elastic member 230 for restoring the movable member 220. The movable member 220 is slidably disposed in the accommodating chamber 400. When the water flow of the external pipe impacts the movable member 220, the movable member 220 can communicate the water outlet chamber 110 with the accommodating chamber 400. When the user closes the external pipe, the water stops impacting the movable member 220, and the movable member 220 can be reset by the elastic member 230 to separate the accommodating chamber 400 from the water outlet chamber 110. As an embodiment, the elastic member 230 may be disposed between the movable member 220 and the spray head 100. Referring to FIG. 5, the movable member 220 has a sealing surface 211. When water impacts the movable member 220, the elastic member 230 is compressed to push the movable member 220 to move away from the spray head 100 after the user closes the external water pipe. The sealing surface 211 may now abut the mounting portion 130 to separate the receiving chamber 400 from the suction chamber 210. In other embodiments, the elastic member 230 may be disposed on a side of the movable member 220 away from the spray head 100. When the water stream impacts the movable member 220, the movable member 220 stretches the elastic member 230 to separate the accommodating chamber 400 from the water outlet chamber 110.

Since the movable member 220 needs to push or stretch the elastic member 230 under the impact of water flow, the movable member 220 should be made of a hard material. However, the moving part 220 made of hard material has a problem of poor sealing. Therefore, in some embodiments, the sealing surface 211 of the movable member 220 may be a side wall of the movable member 220, the mounting portion 130 includes an inner wall 131 located in the receiving cavity 400, and the outer contour of the inner wall 131 is substantially the same as the shape of the movable member 220, so that the movable member 220 can slide along the inner wall 131. A seal is provided on the inner wall 131 along the side of the movable element 220, the seal being disposed around the inner wall 131 and having an outer profile that may be smaller than an outer profile of the movable element 220. Thus, the sealing surface 211 of the movable member 220 can abut against the sealing portion under the driving of the elastic member 230, so that the water outlet chamber 110 is separated from the accommodating chamber 400. To enhance the partitioning effect of the outlet chamber 110 and the receiving chamber 400, a sealing ring 212 may be provided on the sealing surface 211. The seal 212 may be a flexible seal 212 of rubber. The seal ring 212 is disposed between the sealing surface 211 and the inner wall 131.

In some embodiments, the sealing ring 212 may abut against a 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 communicate the accommodating chamber 400 and the water outlet chamber 110 during the sliding of the movable member 220. The elastic sealing ring 212 can be more tightly attached to the sealing portion and the sealing surface 211, so that the sealing effect is better.

In other embodiments, the inner diameter of the portion of the inner wall 131 close to the face cover 140 is larger than the outer diameter of the sealing ring 212, the inner wall 131 is opened with a communication hole 1311, the communication hole 1311 is located at the portion of the inner wall 131 close to the face cover 140, and the communication hole 1311 communicates the accommodating chamber 400 and the water outlet chamber 110. The elastic member 230 is disposed between the face cover 140 and the movable member 220, and the movable member 220 may be disposed in the communication hole 1311 and pushed by the elastic member 230. Since the inner diameter of the inner wall 131 near the surface cover 140 is larger than the outer diameter of the sealing ring 212, when the movable member 220 is located in the section of the communication hole 1311, the sealing ring 212 cannot abut against the inner wall 131, so that the water outlet chamber 110 is communicated with 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, and the accommodating chamber 400 is separated from the water outlet chamber 110.

The movable member 220 may be provided in plurality, and in some embodiments, the flow stop device 200 further includes a connector 240. Referring to fig. 1 again, the plurality of movable members 220 are disposed at one end of the connecting member 240, and the elastic member 230 is disposed between the connecting member 240 and the nozzle, so that the plurality of movable members 220 can move synchronously. In one embodiment, the connecting water flow can impact the connecting member 240 to drive the movable member 220 to connect the water outlet chamber 110 and the accommodating chamber 400. The elastic member 230 can be used to drive the connecting member 240 to return, so that the connecting member 240 drives the movable member 220 to separate the accommodating chamber 400 from the water outlet chamber 110.

The movable member 220 is driven only by the elastic member 230 during the movement, and there is a problem that the movement direction is sometimes deviated. Therefore, in some embodiments, the side of the face cover 140 facing the communication part 300 may be referred to as having the guide hole 141. Referring to fig. 5 again, one end of the elastic element 230 extends into the guiding hole 141 and abuts against the surface cover 140, and the other end abuts against the movable element 220. The diameter of the guide hole 141 may be substantially equal to the diameter of the elastic member 230, so that during the movement of the elastic member 230, the elastic member 230 only moves in the guide hole 141, and the elastic member 230 is not easily deflected, so that the movement track of the movable member 220 is not easily deflected.

The movable member 220 can only ensure that the residual water in the accommodating chamber 400 cannot flow out under the action of gravity, but the residual water in the water outlet chamber 110 still has the problem of flowing out when only the movable member 220 is arranged, so the water suction chamber 210 is arranged on the flow stopping device 200.

In one embodiment, the water suction chamber 210 may be disposed on the movable member 220, and during the resetting process of the movable member 220, the water suction chamber 210 may suck in the residual water in the water outlet chamber 110. In other embodiments, the water suction chamber 210 may also be a structure independent from the movable member 220 and driven by a driving structure different from the elastic member 230, such as a driving structure of a solenoid valve, which is not limited herein. In the present embodiment, the volume in the water suction 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 in the water suction chamber 210 is at the maximum, and a negative pressure is formed in the water suction chamber 210 during the process of expanding the volume in the water suction chamber 210 to the maximum, so that the residual water in the water outlet chamber 110 can be sucked. The residual water in the suction chamber 210 may flow out by gravity if it is too large. In some embodiments, there may be a plurality of water suction chambers 210, a small amount of residual water is stored in each of the water suction chambers 210, a plurality of water outlet chambers 110 are not communicated with each other, and each water suction chamber 210 is communicated with only one water outlet chamber 110. Compared with the case that the water outlet cavities 110 are not communicated with each other, if the water outlet cavities 110 are communicated with each other, the water suction cavity 210 has a poor negative pressure effect, and the residual water in the water outlet cavity 110 cannot be sucked into the water suction cavity 210 better. As an embodiment, the volume of outlet chamber 110 may be smaller than or equal to the volume of water suction chamber 210, so that water suction chamber 210 can completely suck the residual water in outlet chamber 110, and a small amount of residual water is not easy to flow out of water suction chamber 210 under the action of the tension of water itself.

As an embodiment, the suction cavity 210 may have an opening 2101. Meanwhile, the spray head 100 is provided with at least one protrusion 142 on one side toward the movable member 220. The protrusion 142 is at least partially inserted into the water suction chamber 210 along the opening 2101, when the elastic member 230 resets the movable member 220 such that the movable member 220 is away from the protrusion 142, the water suction chamber 210 slides relative to the protrusion 142, so that the water suction chamber 210 generates negative pressure to suck in the residual water in the water outlet chamber 110. Through the design, the movement of the movable piece 220 drives the water suction cavity 210 to suck water, so that the structure is simpler, and meanwhile, the volume of the cut-off device 200 is smaller.

In order to allow residual water to flow from outlet chamber 110 into suction chamber 210, outlet chamber 110 needs to be in communication with suction chamber 210. However, the channel with an excessively large cross section can cause that the residual water body cannot be contained in the water suction cavity 210 for a long time, and the problem that the residual water in the water suction cavity 210 flows out under the action of gravity exists. In some embodiments, referring to fig. 4 again, the protrusion 142 is provided with a water absorbing passage 1421, and the water absorbing passage 1421 communicates the water absorbing cavity 210 and the water outlet cavity 110. It is more convenient to process the water absorbing channel 1421 on the protrusion 142, and the cross section of the water absorbing channel 1421 is smaller, so that the residual water in the water outlet cavity 110 is not easy to naturally flow out. In other embodiments, the protrusion 142 may also be provided with a hole penetrating through the protrusion 142, and the hole can also communicate the water outlet chamber 110 and the water suction chamber 210.

The application principle of the water outlet device 1000 provided by the embodiment of the application is as follows:

in the water outlet apparatus 1000 provided by the present application, the cut-off device 200 is disposed in the accommodating chamber 400 formed between the spray head 100 and the communicating portion 300, and the cut-off device 200 includes the connecting member 240, the movable member 220 and the elastic member 230. And a water suction chamber 210 is formed at the movable member 220. When a user opens the water pipe connected to the outlet device 1000, the connecting member 240 compresses the elastic member 230 under the impact of the water flow, and simultaneously drives the plurality of movable members 220 to connect the accommodating chamber 400 and the outlet chamber 110, so that the water flow can be ejected along the outlet hole 120. When the user closes the water pipe, the connecting member 240 is reset under the driving of the elastic member 230, and at the same time, drives the movable member 220, so that a negative pressure is formed in the water suction chamber 210, and the residual water in the water outlet chamber 110 is sucked through the water suction channel 1421 formed on the protrusion 142, thereby preventing the water in the water outlet chamber 110 and a part of the water pipes from flowing out under the action of gravity after the external water pipe is closed, and wetting the user who has just finished bathing. The application provides a water installation 1000, after outside water pipe stopped supplying water, through cut-off equipment 200, can in time separate out water cavity 110 and hold chamber 400, make hold chamber 400 and with hold the unable outflow of the interior residual water of outside water pipe of chamber 400 intercommunication, be provided with the chamber 210 that absorbs water simultaneously in cut-off equipment 200, the chamber 210 that absorbs water can inhale the residual water in the water cavity 110, the residual water outflow in the water cavity 110 of having avoided, better user experience has.
