[0015] The existing liquid outlet device with descaling function generally adopts an extra designed driving structure to drive the descaling structure to reciprocate so as to descale the liquid outlet hole, which has high cost. The reciprocation of the descaling structure requires a certain space, resulting in a large liquid residual space in the liquid outlet device, which leads to the continuous dripping of residual liquid from the liquid outlet hole after the liquid supply to the liquid outlet device is stopped.

[0016] In order to solve the above technical problems, the embodiments of the present application provide a liquid outlet device and a liquid outlet system. The liquid outlet system can be mounted in various occasions and environments, such as companies, schools, families, factories and the like, to realize cleaning effect and improve and enhance life quality and health of people. The liquid outlet device may be, but is not limited to, one or more combinations of a water outlet faucet, a shower head, a top sprayer and a spray gun. For the convenience of describing the technical solutions of the present application, the following takes the liquid outlet device being a shower head as an example for illustration.

[0017] References are made to FIGS. 1-5 together to explain the liquid outlet system provided by embodiments of the present application. The liquid outlet system includes a liquid outlet device. The liquid outlet device includes a shell assembly 10 and a liquid outlet assembly 20.

[0018] The shell assembly 10 is provided with a liquid inlet channel 100 and at least one liquid division slot 200 disposed on the outer surface of the shell assembly 10. In an embodiment of the present application, a plurality of liquid division slots 200 are provided. It is to be understood that in other embodiments one liquid division slot 200 may be provided.

[0019] The liquid outlet assembly 20 is mounted to the shell assembly 10 and overlays each liquid division slot 200. The liquid outlet assembly 20 includes an elastic member 21 disposed corresponding to each liquid division slot 200. The elastic member 21 may be made of an elastomeric material. In the embodiment of the present application, a plurality of elastic members 21 are provided, and the plurality of elastic members are arranged in one-to-one correspondence with the plurality of liquid division slots 200. The elastic member 21 is provided with at least one liquid outlet hole 300. In an embodiment of the present application, each elastic member 21 is provided with one liquid outlet hole 300. It is understood that in other embodiments, each elastic member 21 may also be provided with a plurality of liquid outlet holes 300.

[0020] The shell assembly 10 is provided with a descaling member 30 corresponding to each liquid outlet hole 300, and each descaling member 30 passes through the corresponding liquid outlet hole 300. The elastic member 21 is partially accommodated in the liquid division slot 200 and elastically abutted against the shell assembly 10, so as to be able to divide the liquid division slot 200 into a first cavity 201 communicated with the liquid inlet channel 100 and a second cavity 202 communicated with the liquid outlet hole 300.

[0021] The elastic member 21 is configured to elastically deform once a liquid pressure of the first cavity 201 exceeds a first preset value, so as to separate the elastic member 21 from the descaling member 30, so that the liquid inlet channel 100 is communicated with the liquid outlet hole 300 through the first cavity 201 and the second cavity 202 in sequence, thus achieving liquid discharge of the liquid outlet device. The liquid outlet device can reset against the liquid pressure less than or equal to the first preset value.

[0022] The liquid outlet system further includes a liquid inlet assembly. The liquid inlet assembly is communicated with the liquid inlet channel 100 and is configured to supply liquid to the liquid inlet channel 100. The liquid inlet assembly may be, but is not limited to, a manually controlled or an electrically controlled valve configuration, and the liquid inlet channel 100 is communicated with or disconnected from a liquid source by opening or closing the liquid inlet assembly. The liquid includes, but is not limited to, clear water or pure water from a municipal water network.

[0023] The first preset value can be set to satisfy that the elastic member 21 is separated from the descaling member 30 under certain conditions, and the descaling member 30 passes through the corresponding liquid outlet hole 300 under certain conditions. In an embodiment of the present application, the first preset value may be set to be less than the liquid pressure when the liquid inlet assembly is opened to supply liquid to the liquid inlet channel 100 and greater than the liquid pressure generated by the liquid remaining in the first cavity 201 after the liquid inlet assembly is closed. That is, after the liquid outlet device is opened, the liquid drives the elastic member 21 to generate elastic deformation, so that the elastic member 21 is separated from the descaling member 30. After the liquid outlet device is closed, the elastic member 21 is reset, and the descaling member 30 passes through the corresponding liquid outlet hole 300 again to complete the descaling of the liquid outlet hole 300.

[0024] In addition, since the elastic member 21 is elastically deformable, when the elastic member 21 resets and the coaxiality of the descaling member 30 and the corresponding liquid outlet hole 300 deviates, the liquid outlet hole 300 can be guided to the descaling member 30 by means of the elastic deformability of the elastic member 21, so that the descaling member 30 can pass through the corresponding liquid outlet hole 300.

[0025] To sum up, the implementation of the embodiments of the present application will have the following beneficial effects: the liquid division device of the above schemes is used and equipped in the liquid outlet system, which can not only realize the descaling function for the liquid outlet hole 300, but also reduce the descaling cost and the residual liquid in the liquid division device by itself. Specifically, the liquid outlet device includes a shell assembly 10 provided with a liquid inlet channel 100 and at least one liquid division slot 200, and a liquid outlet assembly 20 mounted to the shell assembly 10 and overlaying each liquid division slot 200. The liquid outlet assembly 20 includes an elastic member 21, which is disposed corresponding to each liquid division slot 200 and is provided with at least one liquid outlet hole 300. The shell assembly 10 is provided with a descaling member 30 corresponding to each liquid outlet hole 300, and each descaling member 30 is configured to pass through the corresponding liquid outlet hole 300. The elastic member 21 is capable of dividing the liquid division slot 200 into a first cavity 201 communicated with the liquid inlet channel 100 and a second cavity 202 communicated with the liquid outlet hole 300. The elastic member 21 elastically deform once a liquid pressure of the first cavity 201 exceeds a first preset value, so as to separate the elastic member 21 from the descaling member 30, so that the liquid inlet channel 100 is communicated with the liquid outlet hole 300 through the first cavity 201 and the second cavity 202 in sequence. The elastic member 21 can reset against a liquid pressure less than or equal to the first preset value (for example, when the liquid discharge of the liquid outlet device is closed). Therefore, the elastic member 21 can move relative to the descaling member 30, so as to realize descaling of the liquid outlet hole 300. The descaling cost is low, no additional driving structure is needed, and the descaling member 30 does not need the space for reciprocation, thus reducing the space for liquid residue.

[0026] In an exemplary embodiment, referring to FIGS. 3 and 5 together, the elastic member 21 includes an annular arm 211 and a liquid outlet part 212. The liquid outlet hole 300 is disposed in the liquid outlet part 212. The annular arm 211 is annularly disposed around the liquid outlet part 212, a circumferential outer side of the annular arm 211 is fixedly connected with the shell assembly 10. The annular arm 211 is at least partially accommodated in the liquid division slot 200 and elastically abutted against the shell assembly 10. The first cavity 201 is disposed around the annular arm 211, and the annular arm 211 is disposed around the second cavity 202. In this way, the liquid in the first cavity 201 can uniformly act on the annular arm 211, and the synchronization of elastic deformation and reset at each position on the annular arm 211 is ensured, thereby ensuring that the liquid outlet part 212 can move substantially in a straight line relative to the descaling member 30, and ensuring the smoothness of the separation of the liquid outlet part 212 from the descaling member 30 and the descaling member 30 passing through the liquid outlet hole 300 again. In addition, the annular arm 211 can surround the second cavity 202 to isolate the second cavity 202 from the first cavity 201, so that the liquid remaining in the first cavity 201 is prevented from entering the second cavity 202 and being discharged from the liquid outlet hole 300 when liquid discharge of the liquid outlet device is closed. The liquid outlet part 212 has a communication cavity 400 communicated between the second cavity 202 and the liquid outlet hole 300. The descaling member 30 has a columnar shape. One end of the descaling member 30 is disposed in the shell assembly 10 and accommodated in the liquid division slot 200, and the other end of the descaling member 30 is configured to pass through the corresponding liquid outlet hole 300 through the second cavity 202 and the communication cavity 400.

[0027] It may be understood that in other embodiments, a component of the elastic member 21 configured to isolate the first cavity 201 and the second cavity 202 may also be of a non-annular structure, and the first cavity 201 and the second cavity 202 may be isolated from each other by the component mating with the shell assembly 10. At this time, one end of the descaling member 30 disposed in the shell assembly 10 may be accommodated in the liquid division slot 200 or disposed outside the liquid division slot 200.

[0028] In an exemplary embodiment, as shown in FIG. 5, the shell assembly 10 is provided with a mounting hole 500 corresponding to each of the liquid outlet parts 212, and each of the liquid outlet parts 212 is mounted to and movable relative to the corresponding mounting hole 500. In this way, the liquid outlet part 212 can be positioned by providing the mounting hole 500, and the position of the liquid outlet part 212 relative to the shell assembly 10 can be ensured to be stable. Furthermore, the providing of the mounting hole 500 enables the liquid outlet part 212 mounted in the mounting hole 500 to be guided by the shell assembly 10, thereby ensuring the stability of the movement of the liquid outlet part 212 relative to the descaling member 30. A side of the annular arm 211 facing away from the liquid division slot 200 has an annular groove 1000 disposed coaxially with the annular arm 211 to improve the elastic deformability of the annular wall 211.

[0029] In an exemplary embodiment, with continued reference to FIG. 5, the mounting hole 500 includes a columnar segment 501 and a conical segment 502. The conical segment 502 has a large end facing the annular arm 211 and a small end away from the annular arm 211, so that there can be a space for the elastic deformation of the annular arm 211 by providing the conical segment 502. A conical surface of the conical segment 502 formed in the shell assembly 10 can avoid excessive elastic deformation of the annular arm 211 and ensure smooth reset of the elastic member 21.

[0030] The columnar segment 501 communicates with the small end. A columnar surface of the columnar segment 501 formed in the shell assembly 10 can restrict the movement of the liquid outlet part 212 and serve as a guide. With the above arrangement, the mounting hole 500 can reduce the contact area between the hole wall (conical surface and columnar surface as a whole) and the elastic member 21, and avoid a high friction resistance between the elastic member 21 and the hole wall which affects the normal elastic deformation and reset of the elastic member 21 while playing a role of guiding. As shown in FIG. 3, in the embodiment of the present application, the liquid outlet part 212 has a cylindrical structure. It may be understood that in other embodiments, the liquid outlet part 212 may also have a columnar structure with other cross-sectional shapes.

[0031] In an exemplary embodiment, as shown in FIGS. 3 and 5, the descaling member 30 includes a connecting part 31 and a descaling part 32. The descaling part 32 is disposed in the shell assembly 10 by the connecting part 31 and can pass through the corresponding liquid outlet hole 300 to descale the liquid outlet hole 300. An outer wall of the connecting part 31 has an arc shape, so as to reduce the resistance to the liquid, thereby preventing the descaling member 30 from vibrating under the drive of the liquid.

[0032] In an exemplary embodiment, referring to FIG. 3 and FIG. 5 to FIG. 8 together, the liquid outlet assembly 20 further includes a body 22 fixedly connected to the shell assembly 10, and a side of the body 22 facing the liquid division slot 200 is fit against the shell assembly 10 and the side and the shell assembly 10 enclose and form a liquid outlet channel 600, through which the liquid inlet channel 100 and the liquid division slot 200 are communicated. The body 22 is made of an elastomeric material, and the shell assembly 10 can clamp the body 22 from a side of the body 22 facing the liquid division slot 200 and a side of the body 22 facing away from the liquid division slot 200. The shell assembly 10 can clamp the body 22, which can ensure that the body 22 is kept at a stable position under the impact of liquid, thereby ensuring that the shape of the liquid division slot 200 remains unchanged, so that the liquid can flow along a preset direction.

[0033] In this way, the liquid can enter the first cavity 201 through the adjustment and guidance of the liquid outlet channel 600, so that the liquid flow has certain directivity and smoothness, and the liquid can flow rapidly to the liquid division slot 200. As shown in FIGS. 6 and 7, the liquid outlet channel 600 may form a groove structure 601 in the body 22 and be overlaid by the shell assembly 10. As shown in FIGS. 3 and 8, the liquid outlet channel 600 may form a groove structure 601 in the shell assembly 10 and be overlaid by the body 22. It may be understood that in other embodiments, the liquid outlet channel 600 may also form groove structures 601 in the body 22 and the shell assembly 10, respectively, and the groove structures 601 enclose and form the liquid outlet channel 600.

[0034] In an exemplary embodiment, referring to FIG. 4, FIG. 6 and FIG. 7 together, the liquid inlet channel 100 can form a liquid discharge opening 101 in the shell assembly 10, and the liquid outlet assembly 20 also includes a protrusion part 23. The circumferential outer side of the protrusion part 23 is connected with the body 22. The protrusion part 23 is disposed opposite to the liquid discharge opening 101 and elastically abuts against the shell assembly 10 to seal the liquid discharge opening 101. The protrusion part 23 is configured to elastically deform when the liquid pressure of the liquid inlet channel 100 exceeds a second preset value, so that the liquid discharge opening 101 communicates with the liquid outlet channel 600. The protrusion part 30 can reset against the liquid pressure less than or equal to the second preset value.

[0035] The protrusion part 23 can elastically abut against the shell assembly 10 to seal the liquid discharge opening 101 disposed opposite to the protrusion part 23, so that the liquid can act positively on the protrusion part 23 when the liquid pressure of the liquid inlet channel 100 exceeds the second preset value, thus ensuring the uniformity of elastic deformation of the protrusion part 23, ensuring the synchronization of elastic deformation of each portion of the protrusion part 23, and avoiding the protrusion part 30 from being unable to reset due to excessive local deformation. The protrusion part 23 can reset against a liquid pressure less than or equal to the second preset value (for example, when the liquid discharge of the liquid outlet device is closed), thereby ensuring the sealing of the liquid discharge opening 101 and preventing the liquid remaining in the liquid inlet channel 100 from being discharged from the liquid discharge opening 101 and into the liquid outlet channel 600. Meanwhile, the liquid remaining in the liquid outlet channel 600 cannot continue to flow into the first cavity 201 and be discharged from the liquid outlet hole 300 due to isolation between the first cavity 201 and the second cavity 202 by the elastic member 21. The liquid in the liquid outlet hole 300 cannot be discharged from the liquid outlet hole 300 under an action of atmospheric pressure, a self-adsorption capacity, shape of the liquid outlet hole 300, etc., so that the residual liquid cannot be discharged from the liquid outlet hole 300 after the liquid discharge of the liquid outlet device is closed, and the user experience is improved. Since the body 22 is fixedly connected to the shell assembly 10, a circumferential outer side of the protrusion part 23 is connected to the body 22, ensuring the position accuracy of the protrusion part 23 during the elastic deformation and reset process, thereby ensuring that the elastic deformation and reset can be stably performed.

[0036] The second preset value can be set to satisfy that the liquid discharge opening 101 is communicated with the liquid outlet channel 600 under certain conditions, and the liquid discharge opening 101 is disconnected from the liquid outlet channel 600 under certain conditions. In an embodiment of the present application, the second preset value may be set to be less than the liquid pressure when the liquid inlet assembly is opened to supply liquid to the liquid inlet channel 100 and greater than the liquid pressure generated by the liquid remaining in the liquid inlet channel 100 after the liquid inlet assembly is closed. That is, the liquid drives the protrusion part 23 to elastically deform after liquid discharge of the liquid outlet device is opened, so that the liquid discharge opening 101 communicates with the liquid outlet channel 600; and the protrusion part 23 is reset after the liquid discharge of the liquid outlet device is closed, so as to ensure the sealing of the liquid discharge opening 101 and prevent the liquid remaining in the liquid inlet channel 100 from being discharged from the liquid discharge opening 101 and into the liquid outlet channel 600.

[0037] In an exemplary embodiment, referring to FIG. 4, FIG. 6 and FIG. 7 together, a side of the protrusion part 23 facing away from the liquid discharge opening 101 has a cavity 700. Thus, the arrangement of the cavity 700 can increase the elastic deformation of the protrusion part 23 generated when the liquid pressure of the liquid inlet channel 100 exceeds the second preset value, thereby ensuring the communication between the liquid discharge opening 101 and the liquid outlet channel 600. In addition, in some exemplary embodiments, the protrusion part 23 may also be a solid structure that elastically deforms with its own elastic deformation capability when the liquid pressure of the liquid inlet channel 100 exceeds the second preset value. It may be understood that in other embodiments a reset member may also be provided in the cavity 700 to enhance a reset performance of the protrusion part 23. The reset member can be a spring or an elastic structure made of other elastic materials. The elastic deformation ability of the protrusion part 23 can be adjusted by changing parameters, such as its material and size.

[0038] In an exemplary embodiment, referring to FIG. 6 and FIG. 7 together, the shell assembly 10 is provided with an accommodating groove 800, the liquid outlet channel 600 is communicated with the accommodating groove 800. The protrusion part 23 is at least partially received in the accommodating groove 800. The protrusion part 23 is configured to elastically deform when the liquid pressure of the liquid inlet channel 100 exceeds the second preset value, so that the liquid discharge opening 101 is communicated with the accommodating groove 800. In this way, by the arrangement of the accommodating groove 800, at least a portion of the protrusion part 23 can be accommodated by the accommodating groove 800, so that during the elastic deformation and reset of the protrusion part 23, the accommodating groove 800 plays a limiting and guiding role to ensure that the elastic deformation and reset can be achieved as desired, thereby ensuring that the liquid discharge opening 101 and the liquid outlet channel 600 can communicate with each other after the elastic deformation of the protrusion part 23, and ensuring that the liquid discharge opening 101 can be sealed after the protrusion part 23 is reset.

[0039] In an exemplary embodiment, referring to FIG. 6 and FIG. 7 together, the protrusion part 23 is at least partially accommodated in the liquid discharge opening 101 to further enhance the sealing of the protrusion part 23 to the liquid discharge opening 101. The liquid discharge opening 101 also can play a limiting and guiding role for the protrusion part 23, ensuring that the elastic deformation and reset of the protrusion part 23 can meet expectations during the elastic deformation and reset of the protrusion part 23. Meanwhile, the protrusion part 23 is at least partially accommodated in the liquid discharge opening 101, so that a gap is easily generated between the protrusion part 23 and the shell assembly 10 after the protrusion part 23 is elastically deformed, so as to facilitate rapid communication between the liquid discharge opening 101 and the liquid outlet channel 600.

[0040] In an exemplary embodiment, referring to FIG. 6 and FIG. 7 together, the liquid outlet channel 600 is communicated with the cavity 700, so that when the protrusion part 23 is elastically deformed, the air in the cavity 700 can be discharged through the liquid outlet channel 600, which facilitates the elastic deformation of the protrusion part 23 and ensures smooth communication between the liquid discharge opening 101 and the liquid outlet channel 600. After the liquid outlet device is closed, the liquid pressure of the liquid inlet channel 100 is less than or equal to the second preset value, the protrusion part 23 is reset, and the air in the liquid outlet channel 600 enters the cavity 700 under the action of atmospheric pressure, so as to ensure that the protrusion part 23 can be completely reset. At the same time, after the air in the liquid outlet channel 600 enters the cavity 700, the outside air is replenished into the liquid outlet channel 600 through the liquid outlet hole 300, while the liquid remaining in the liquid outlet hole 300, the liquid division slot 200 and the liquid outlet channel 600 is pushed to flow toward a side away from the liquid outlet hole 300, further preventing the residual liquid from being discharged from the liquid outlet hole 300. In addition, the communication between the liquid outlet channel 600 and the cavity 700 can further prevent excessive pressure in the cavity 700 which damages the stability of the connection between the shell assembly 10 and the liquid outlet assembly 20.

[0041] In an exemplary embodiment, referring to FIG. 3, FIG. 6 to FIG. 8 together, a plurality of liquid outlet channels 600 are provided, and the multiple liquid outlet channels 600 are provided around the protrusion part 23. Because the protrusion part 23 is disposed opposite to the liquid discharge opening 101, the liquid can uniformly enter each liquid outlet channel 600 after driving the protrusion part 23 to elastically deform, thus providing the possibility for the liquid outlet device to uniformly discharge liquid subsequently. A plurality of liquid division slots 200 are provided, and each liquid outlet channel 600 is communicated with at least one liquid division slot 200.

[0042] In an exemplary embodiment, referring to FIG. 6 and FIG. 7 together, a side of the protrusion part 23 facing the liquid discharge opening 101 has a guide surface 231 which is configured to be elastically deformed with the protrusion part 23 to guide the liquid to the liquid outlet channel 600. In this way, the arrangement of the guide surface 231 can facilitate the liquid to enter the liquid outlet channel 600, thereby guiding the flow direction of the liquid to a certain extent.

[0043] In an exemplary embodiment, as shown in FIG. 6, the guide surface 231 is a spherical crown. This enables a linear seal to be formed between the protrusion part 23 and the shell assembly 10. At this time, the top end of the protrusion part 23 is located in the liquid inlet channel 100 and seals the liquid discharge opening 101. In an embodiment of the present application, the shell assembly 10 is provided with an accommodating groove 800. The remaining portion of the protrusion part 23 is located in the accommodating groove 800, so that through the arrangement of the accommodating groove 800, the accommodating groove 800 plays a limiting and guiding role during the elastic deformation and reset of the protrusion part 23, thus ensuring that the elastic deformation and reset can meet expectations, and further ensuring that the liquid discharge opening 101 and the liquid outlet channel 600 can communicate after the protrusion part 23 is elastically deformed, and ensuring that the liquid discharge opening 101 can be sealed after the protrusion part 23 is reset. In addition, in some exemplary embodiments, the protrusion part 23 may also form a linear seal with a groove opening of the accommodating groove 800 formed in the shell assembly 10 to prevent residual liquid in the accommodating groove 800 from entering the liquid outlet channel 600.

[0044] In another exemplary embodiment, as shown in FIG. 7, the protrusion part 23 includes a circumferential wall 232 and a connection wall 233. The circumferential wall 232 is bent toward the connection wall 233 and connected with a periphery of the connection wall 233 to form a guide surface 231 on a side of the circumferential wall 232 facing away from the connection wall 233. This enables an end face sealing to be formed between the protrusion part 23 and the shell assembly 10. At this time, the protrusion part 23 is integrally positioned outside of the liquid inlet channel 100 and seals the liquid discharge opening 101. In an embodiment of the present application, the shell assembly 10 is provided with an accommodating groove 800. The protrusion part 23 can be integrally located in the accommodating groove 800, so that the accommodating groove 800 plays a limiting and guiding role in the elastic deformation and reset processes of the protrusion part 23 through the arrangement of the accommodating groove 800, ensuring that the elastic deformation and reset can meet expectations, thereby ensuring that the liquid discharge opening 101 and the liquid outlet channel 600 can communicate after the protrusion part 23 is elastically deformed, and ensuring that the liquid discharge opening 101 can be sealed after the protrusion part 23 is reset. The liquid acts on the connection wall 233 in order that the circumferential wall 232 bends toward the connection wall 233, so that the guide surface 231 directly faces the liquid discharge opening 101 to guide the liquid to the liquid outlet channel 600. The protrusion part 23 can seal by sealing means other than linear sealing and end face sealing.

[0045] As shown in FIG. 7, the circumferential wall 232 and the connection wall 233 can enclose and form a notch 900. The notch 900 is disposed opposite to the liquid discharge opening 101. In this way, through the arrangement of the notch 900, the action position of the liquid acting on the protrusion part 23 can be positioned, which facilitates that the protrusion part 23 can elastically deform according to a preset, so that each portion of the circumferential wall 232 can be elastically deformed synchronously, and the fluid can enter the multiple liquid outlet channels 600 at the same time, thus improving the liquid outlet effect of the liquid outlet device.

[0046] In an exemplary embodiment, referring to FIG. 3 and FIG. 8 together, the liquid outlet channel 600 extends at least partially offset from a radial direction of the protrusion part 23, such that the liquid outlet channel 600 can accommodate more residual liquid, further avoiding the discharge of residual liquid from the liquid outlet hole 300.

[0047] In an exemplary embodiment, referring to FIGS. 1, 2 and 4-8 together, the shell assembly 10 includes a face cover 11, a rear shell 12, an inner bracket 13, a ball head 14, a ball head sleeve 15, and a nut 16. The face cover 11 and the rear shell 12 enclose and form a mounting space, the inner bracket 13 and the liquid outlet assembly 20 are mounted in the mounting space. The inner bracket 13 is connected with the rear shell 12, and the liquid outlet assembly 20 can be abutted against the face cover 11, so that the inner bracket 13 and the face cover 11 can clamp the liquid outlet assembly 20. The liquid division slot 200 is provided in the inner bracket 13. The descaling member 30 is provided in the inner bracket 13 and partially located in the liquid division slot 200. The mounting hole 500 is provided in the face cover 11. The inner bracket 13 and the body 22 enclose and form a liquid outlet channel 600.

[0048] The liquid inlet channel 100 penetrates through the ball head 14 and extends into the inner bracket 13, a liquid discharge opening 101 is formed in the inner bracket 13. The nut 16 is in threaded connection with the inner bracket 13 to press the ball head 14 on the inner bracket 13 through the ball head sleeve 15, so as to restrict the movement of the ball head 14 relative to the inner bracket 13. Meanwhile, the ball head 14 is fit against the arc-shaped surface of the ball head sleeve 15 to facilitate the rotation of the ball head 14 relative to the inner bracket 13, so as to adjust the orientation of the face cover 11 and further adjust the direction of liquid discharge. In order to reduce the wear when the ball head 14 rotates relative to the inner bracket 13, a gasket 17 is further provided between the ball head 14 and the inner bracket 13. At the same time, a sealing member 18 is further provided between the gasket 17, the inner bracket 13, and the ball head 14, to prevent liquid from being discharged between the inner bracket 13 and the ball head 14. In order to save water resources, a flow limiting sheet 19 is further provided in the liquid inlet channel 100 to keep the liquid outlet amount of the liquid outlet device constant and save the liquid consumption.
