[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 28, 2023, with application number 202323239258.0 and invention name “Liquid Outlet Device and Liquid Outlet System”, the contents of which should be understood as incorporated into this application by reference. Technical Field

[0002] The embodiments of the present disclosure relate to but are not limited to kitchen and bathroom technologies, and in particular to a liquid discharge device and a liquid discharge system. Background Art

[0003] Some liquid discharge devices with a descaling function generally use an additionally designed driving structure to drive the descaling structure to move back and forth to descale the liquid discharge hole, which is costly. In addition, the reciprocating movement of the descaling structure requires a certain amount of space, resulting in a large residual liquid space in the liquid discharge device, which results in residual liquid continuously dripping from the liquid discharge hole after the liquid supply to the liquid discharge device is stopped.

The cover is constructed so that the at least one cover is constructed so that the container is flush with the surface of the container. The cover is then connected to a plurality of side walls of the container. The container is flushed with the surface of the container.

[0007] The embodiment of the present disclosure further provides a liquid outlet system, comprising: the liquid outlet device as described above.

[0008] Implementing the embodiments of the present disclosure will have the following beneficial effects:

[0009] The liquid separation device of the above scheme is applied to the liquid discharge system. In addition to achieving the descaling efficiency of the liquid discharge hole, it can also reduce the descaling cost and reduce the residual liquid in the liquid separation device. Specifically, the liquid discharge device includes a housing assembly provided with a liquid inlet channel and at least one liquid separation groove, and a liquid discharge assembly mounted on the housing assembly and sealing each liquid separation groove. The liquid discharge assembly includes an elastic member provided corresponding to each liquid separation groove and provided with at least one liquid discharge hole, and the housing assembly is provided with a descaling member corresponding to each liquid discharge hole, and each descaling member is provided through the corresponding liquid discharge hole. The elastic member can separate the liquid separation groove into a first cavity connected to the liquid inlet channel and a second cavity connected to the liquid discharge hole. When the liquid pressure in the first cavity exceeds a first preset value, the elastic member undergoes elastic deformation to separate from the descaling member, so that the liquid inlet channel is connected to the liquid discharge hole through the first cavity and the second cavity in sequence, and can be reset by resisting the liquid pressure less than or equal to the first preset value (such as when the liquid discharge device is closed). In this way, the elastic member can move relative to the descaling member to achieve descaling of the liquid outlet. The descaling cost is low, no additional driving structure is required, and the descaling member does not need space for reciprocating movement, reducing the space for liquid residue.

[0026] Some liquid discharge devices with a descaling function generally use an additionally designed driving structure to drive the descaling structure to move back and forth to descale the liquid discharge hole, which is costly. In addition, the reciprocating movement of the descaling structure requires a certain amount of space, resulting in a large residual liquid space in the liquid discharge device, which results in residual liquid continuously dripping from the liquid discharge hole after the liquid supply to the liquid discharge device is stopped.

[0027] The present disclosure provides a liquid discharge device and system that can be installed in various environments, such as offices, schools, homes, and factories, to achieve effective cleaning effects and enhance people's quality of life and health. The liquid discharge device can be, but is not limited to, a faucet, a showerhead, an overhead spray, or a spray gun, or a combination thereof. To facilitate the description of the disclosed technical solution, the following description uses a showerhead as an example.

[0028] The liquid outlet system provided by the embodiment of the present disclosure will now be described in conjunction with Figures 1 to 5. The liquid outlet system includes a liquid outlet device. The liquid outlet device includes a housing assembly 10 and a liquid outlet assembly 20.

[0029] The housing assembly 10 is provided with a liquid inlet channel 100 and at least one liquid separator 200, which is disposed on the outer surface of the housing assembly 10. In the disclosed embodiment, there are multiple liquid separators 200. It is understood that in other embodiments, there may also be one liquid separator 200.

[0030] The liquid outlet assembly 20 is installed on the housing assembly 10 and seals each liquid separation groove 200. The liquid outlet assembly 20 includes an elastic member 21 provided corresponding to each liquid separation groove 200. The elastic member 21 can be made of an elastomeric material. In the embodiment of the present disclosure, the number of elastic members 21 is multiple and they are provided in a one-to-one correspondence with the multiple liquid separation grooves 200. The elastic member 21 is provided with at least one liquid outlet hole 300. In the embodiment of the present disclosure, each elastic member 21 is provided with one liquid outlet hole 300. It can be understood that in other embodiments, each elastic member 21 can also be provided with multiple liquid outlet holes 300.

[0031] The housing assembly 10 is provided with a descaling member 30 corresponding to each liquid outlet 300, and each descaling member 30 is disposed through the corresponding liquid outlet 300. The elastic member 21 is partially housed in the liquid separation groove 200 and elastically abuts against the housing assembly 10, thereby separating the liquid separation groove 200 into a first cavity 201 communicating with the liquid inlet channel 100 and a second cavity 202 communicating with the liquid outlet 300.

[0032] The elastic member 21 is configured to undergo elastic deformation when the liquid pressure in the first cavity 201 exceeds a first preset value, so as to separate from the descaling member 30, so that the liquid inlet channel 100 is connected with the liquid outlet 300 through the first cavity 201 and the second cavity 202 in sequence, thereby realizing liquid discharge from the liquid outlet device and being able to resist the action of liquid pressure less than or equal to the first preset value and reset.

[0033] The liquid outlet system also includes a liquid inlet assembly. The inlet assembly is connected to the liquid inlet channel 100 and is configured to supply liquid to the channel. The inlet assembly can be, but is not limited to, a manually or electrically controlled valve structure. Opening or closing the inlet assembly connects or disconnects the liquid inlet channel 100 from the liquid source. Liquids include, but are not limited to, clean or purified water from a municipal water network.

[0034] The first preset value can be set to ensure that the elastic member 21 and the descaling member 30 are separated under certain conditions, and that the descaling member 30 is inserted into the corresponding liquid outlet 300 under certain conditions. In the disclosed embodiment, the first preset value can be set to be less than the liquid pressure when the liquid inlet assembly is turned on 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 turned off. That is, after the liquid outlet device is turned on to discharge liquid, the liquid drives the elastic member 21 to elastically deform, causing the elastic member 21 to separate from the descaling member 30. After the liquid outlet device is turned off to discharge liquid, the elastic member 21 returns to its original position, and the descaling member 30 is re-inserted into the corresponding liquid outlet 300, completing the descaling of the liquid outlet 300.

[0035] In addition, since the elastic member 21 is elastically deformable, when the elastic member 21 is reset and there is a deviation in the coaxiality between the descaling member 30 and the corresponding liquid outlet hole 300, the elastic deformation ability of the elastic member 21 can be utilized to guide the liquid outlet hole 300 toward the descaling member 30, so that the descaling member 30 can be passed through the corresponding liquid outlet hole 300.

[0036] In summary, the implementation of the embodiments of the present disclosure will have the following beneficial effects: the liquid separation device of the above-mentioned scheme is applied to the liquid outlet system. In addition to being able to achieve the descaling efficiency of the liquid outlet hole 300, it itself can also reduce the descaling cost and reduce the residual liquid in the liquid separation device. Specifically, the liquid outlet device includes a shell assembly 10 provided with a liquid inlet channel 100 and at least one liquid separation tank 200, and a liquid outlet assembly 20 installed on the shell assembly 10 and sealing each liquid separation tank 200. Among them, the liquid outlet assembly 20 includes an elastic member 21 provided corresponding to each liquid separation tank 200 and provided with at least one liquid outlet hole 300, and the shell assembly 10 is provided with a descaling member 30 corresponding to each liquid outlet hole 300, and each descaling member 30 is passed through the corresponding liquid outlet hole 300. The elastic member 21 can separate the liquid separation tank 200 into a first cavity 201 connected to the liquid inlet channel 100 and a second cavity 202 connected to the liquid outlet hole 300. When the liquid pressure in the first cavity 201 exceeds a first preset value, the elastic member 21 elastically deforms and separates from the descaling member 30, allowing the liquid inlet channel 100 to communicate with the liquid outlet 300 through the first cavity 201 and the second cavity 202, respectively. The elastic member 21 is capable of resisting liquid pressure equal to or less than the first preset value (e.g., when the liquid outlet device is closed) and returning to its original position. This allows the elastic member 21 to move relative to the descaling member 30 to remove scale from the liquid outlet 300, resulting in lower descaling costs and no need for an additional drive structure. Furthermore, the descaling member 30 does not require space for reciprocating movement, reducing the space for liquid residue.

[0037] In an exemplary embodiment, referring to Figures 3 and 5 , the elastic member 21 includes an annular arm 211 and a liquid outlet portion 212. A liquid outlet hole 300 is provided in the liquid outlet portion 212. The annular arm 211 is disposed around the liquid outlet portion 212, and the outer circumferential side of the annular arm 211 is fixedly connected to the housing assembly 10. The annular arm 211 is at least partially housed in the liquid separation groove 200 and elastically abuts against the housing 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. This allows the liquid in the first cavity 201 to act more evenly on the annular arm 211, ensuring synchronization of elastic deformation and reset at each position of the annular arm 211, thereby ensuring that the liquid outlet portion 212 can move approximately linearly relative to the descaling member 30, ensuring smooth separation of the liquid outlet portion 212 from the descaling member 30, and smooth re-entry of the descaling member 30 into the liquid outlet hole 300. Furthermore, the annular arm 211 surrounds the second cavity 202, isolating the second cavity 202 from the first cavity 201. This prevents liquid remaining in the first cavity 201 from entering the second cavity 202 and being discharged through the liquid outlet 300 when the liquid outlet device is closed. The liquid outlet 212 includes a connecting cavity 400 connecting the second cavity 202 and the liquid outlet 300. The descaling member 30 is cylindrical, with one end disposed in the housing assembly 10 and housed in the liquid separator 200. The other end passes through the second cavity 202 and the connecting cavity 400 and is disposed in the corresponding liquid outlet 300.

[0038] It is understood that in other embodiments, the elastic member 21 configured to isolate the first cavity 201 from the second cavity 202 may also be a non-annular structure, and can be used to isolate the first cavity 201 from the second cavity 202 by cooperating with the housing assembly 10. In this case, the descaling member 30 disposed at one end of the housing assembly 10 can be accommodated in the liquid separation tank 200 or disposed outside the liquid separation tank 200.

[0039] In an exemplary embodiment, as shown in FIG5 , the housing assembly 10 is provided with a mounting hole 500 corresponding to each liquid outlet portion 212, and each liquid outlet portion 212 is mounted in a corresponding mounting hole 500 and can move relative to the corresponding mounting hole 500. Thus, the liquid outlet portion 212 can be positioned by the provision of the mounting holes 500, ensuring that the position of the liquid outlet portion 212 relative to the housing assembly 10 is stable. Furthermore, the provision of the mounting holes 500 allows the liquid outlet portion 212 mounted in the mounting holes 500 to be guided by the housing assembly 10, ensuring the stability of the movement of the liquid outlet portion 212 relative to the descaling component 30. The annular arm 211 has an annular groove 1000 coaxially arranged with the annular arm 211 on the side facing away from the liquid separation groove 200, so as to enhance the elastic deformation capability of the annular wall 211.

[0040] In an exemplary embodiment, please continue to refer to Figure 5, the mounting hole 500 includes a columnar section 501 and a conical section 502, the conical section 502 has a large end facing the annular arm 211 and a small end away from the annular arm 211, so that the setting of the conical section 502 can avoid the elastic deformation of the annular arm 211, and the conical surface formed by the conical section 502 on the shell assembly 10 can avoid excessive elastic deformation of the annular arm 211, thereby ensuring that the elastic member 21 can be smoothly reset.

[0041] The columnar section 501 is connected to the small end portion. The cylindrical surface formed by the columnar section 501 in the housing assembly 10 can limit the movement of the liquid outlet portion 212 and play a guiding role. The mounting hole 500 can reduce the contact area between the hole wall (the cone and the cylindrical surface as a whole) and the elastic member 21 through the above-mentioned arrangement. While playing a guiding role, it avoids the generation of large friction resistance between the elastic member 21 and the hole wall, which affects the normal elastic deformation and reset of the elastic member 21. As shown in Figure 3, in the embodiment of the present disclosure, the liquid outlet portion 212 has a cylindrical structure. It can be understood that in other embodiments, the liquid outlet portion 212 may also have a columnar structure with other cross-sectional shapes.

[0042] In an exemplary embodiment, as shown in Figures 3 and 5, the descaling member 30 includes a connecting portion 31 and a descaling portion 32. The descaling portion 32 is disposed on the housing assembly 10 via the connecting portion 31 and can penetrate the corresponding liquid outlet 300 to descaling the liquid outlet 300. The outer wall of the connecting portion 31 is curved to reduce resistance to the liquid, thereby preventing the descaling member 300 from vibrating when driven by the liquid.

[0043] In an exemplary embodiment, please refer to Figures 3 and 5 to 8 together, the liquid outlet component 20 also includes a body 22, the body 22 is fixedly connected to the shell component 10, and the side of the body 22 facing the liquid separation tank 200 is attached to the shell component 10 and enclosed with the shell component 10 to form a liquid outlet channel 600, and the liquid inlet channel 100 and the liquid separation tank 200 are connected through the liquid outlet channel 600. The body 22 is made of an elastomeric material, and the shell component 10 can clamp the body 22 from the side of the body 22 facing the liquid separation tank 200 and the side away from the liquid separation tank 200. The shell component 10 can clamp the body 22, which can ensure that the body 22 maintains a stable position under the impact of the liquid, thereby ensuring that the shape of the liquid separation tank 200 remains unchanged, so that the liquid can flow in a preset direction.

[0044] In this way, the liquid can enter the first cavity 201 after the rectifying effect of the liquid outlet channel 600, so that the flow of the liquid has a certain directionality and smoothness, so that the liquid can flow to the liquid separation tank 200 more quickly. As shown in Figures 6 and 7, the liquid outlet channel 600 can form a groove structure 601 in the main body 22 and be covered by the shell assembly 10. As shown in Figures 3 and 8, the liquid outlet channel 600 can form a groove structure 601 in the shell assembly 10 and be covered by the main body 22. It can be understood that in other embodiments, the liquid outlet channel 600 can also form a groove structure 601 in the main body 22 and the shell assembly 10 respectively, and enclose the liquid outlet channel 600.

[0045] In an exemplary embodiment, referring to Figures 4, 6, and 7, the liquid inlet channel 100 can form a liquid outlet 101 in the housing assembly 10. The liquid outlet assembly 20 further includes a protrusion 23, the circumferential outer side of which is connected to the body 22. The protrusion 23 is disposed opposite the liquid outlet 101 and elastically abuts against the housing assembly 10 to seal the liquid outlet 101. The protrusion 23 is configured to elastically deform when the liquid pressure in the liquid inlet channel 100 exceeds a second preset value, thereby connecting the liquid outlet 101 to the liquid outlet channel 600, and can be reset by resisting the action of liquid pressure less than or equal to the second preset value.

[0046] The raised portion 23 can elastically abut against the housing assembly 10, sealing the liquid outlet 101 opposite thereto. This allows the liquid to positively act on the raised portion 23 when the liquid pressure in the liquid inlet channel 100 exceeds a second preset value, thereby ensuring uniform elastic deformation of the raised portion 23 and synchronizing elastic deformation of various portions of the raised portion 23, thereby preventing excessive local deformation of the raised portion 23 from causing it to be unable to reset. The raised portion 23 can also be reset against liquid pressures less than or equal to the second preset value (e.g., when the liquid outlet device is closed), thereby ensuring the sealing of the liquid outlet 101 and preventing liquid remaining in the liquid inlet channel 100 from being discharged from the liquid outlet 101 into the liquid outlet channel 600. Furthermore, liquid remaining in the liquid outlet channel 600 is unable to continue flowing into the first cavity 201 due to the isolation between the first cavity 201 and the second cavity 202 by the elastic member 21, and is discharged from the liquid outlet 300. Liquid within the liquid outlet 300 is prevented from draining out of the liquid outlet 300 due to atmospheric pressure, its own adsorption capacity, and the shape of the liquid outlet 300. Consequently, after the liquid outlet device is closed, any remaining liquid cannot be drained out of the liquid outlet 300, thereby improving the user experience. Because the body 22 is fixedly connected to the housing assembly 10 and the circumferential outer side of the protrusion 23 is connected to the body 22, the positional accuracy of the protrusion 23 during elastic deformation and resetting is ensured, thereby ensuring stable elastic deformation and resetting.

[0047] The second preset value can be set to ensure that the liquid outlet 101 is connected to the liquid outlet channel 600 under certain conditions and disconnected from the liquid outlet channel 600 under certain conditions. In the embodiment of the present disclosure, the second preset value can 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, after the liquid outlet device is opened to discharge liquid, the liquid drives the protrusion 23 to elastically deform, thereby connecting the liquid outlet 101 with the liquid outlet channel 600. After the liquid outlet device is closed to discharge liquid, the protrusion 23 returns to its original position, ensuring the sealing of the liquid outlet 101 and preventing the liquid remaining in the liquid inlet channel 100 from being discharged from the liquid outlet 101 into the liquid outlet channel 600.

[0048] In an exemplary embodiment, please refer to Figures 4, 6 and 7 together, the side of the protrusion 23 facing away from the liquid outlet 101 has a cavity 700. In this way, the provision of the cavity 700 can increase the amount of elastic deformation of the protrusion 23 when the liquid pressure in the liquid inlet channel 100 exceeds the second preset value, so as to ensure the connectivity between the liquid outlet 101 and the liquid outlet channel 600. In addition, in some exemplary embodiments, the protrusion 23 may also be a solid structure, which utilizes its own elastic deformation ability to elastically deform when the liquid pressure in the liquid inlet channel 100 exceeds the second preset value. It can be understood that in other embodiments, a reset member may also be provided in the cavity 700 to enhance the reset performance of the protrusion 23. The reset member may be an elastic structure made of a spring or other elastic material. The elastic deformation ability of the protrusion 23 can be adjusted by changing parameters such as its material and size.

[0049] In an exemplary embodiment, referring to Figures 6 and 7 , the housing assembly 10 is provided with a receiving groove 800, the liquid outlet channel 600 is connected to the receiving groove 800, and the protrusion 23 is at least partially accommodated in the receiving groove 800. The protrusion 23 is configured to elastically deform when the liquid pressure in the liquid inlet channel 100 exceeds a second preset value, so that the liquid outlet 101 is connected to the receiving groove 800. In this way, the provision of the receiving groove 800 can at least partially accommodate the protrusion 23, so that during the elastic deformation and reset process of the protrusion 23, it plays a limiting and guiding role, ensuring that the elastic deformation and reset can be achieved as expected, thereby ensuring that the liquid outlet 101 and the liquid outlet channel 600 can be connected after the elastic deformation of the protrusion 23, and ensuring that the liquid outlet 101 can be sealed after the protrusion 23 is reset.

[0050] In an exemplary embodiment, referring to Figures 6 and 7 , the protrusion 23 is at least partially housed within the liquid outlet 101 to further enhance the sealing performance of the protrusion 23 with respect to the liquid outlet 101. The liquid outlet 101 can also serve as a limiting guide for the protrusion 23, ensuring that the elastic deformation and resetting of the protrusion 23 are as expected during the elastic deformation and resetting process. Furthermore, the protrusion 23 is at least partially housed within the liquid outlet 101, so that after the elastic deformation of the protrusion 23 occurs, a gap is easily generated between the protrusion 23 and the housing assembly 10, thereby facilitating rapid connection between the liquid outlet 101 and the liquid outlet channel 600.

[0051] In an exemplary embodiment, please refer to Figures 6 and 7 together, the liquid outlet channel 600 is connected to the cavity 700, so that when the protrusion 23 is elastically deformed, the air in the cavity 700 can be discharged through the liquid outlet channel 600 to facilitate the elastic deformation of the protrusion 23, thereby ensuring smooth communication between the liquid outlet 101 and the liquid outlet channel 600. After the liquid outlet device closes the liquid outlet, the liquid pressure in the liquid inlet channel 100 is less than or equal to the second preset value, the protrusion 23 is reset, and the air in the liquid outlet channel 600 enters the cavity 700 under the action of atmospheric pressure to ensure that the protrusion 23 can be completely reset. Moreover, after the air in the liquid outlet channel 600 enters the cavity 700, the outside air will replenish the liquid inlet and outlet channel 600 through the liquid outlet hole 300, and push the liquid remaining in the liquid outlet hole 300, the liquid separation tank 200 and the liquid outlet channel 600 to flow to the 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 connection between the liquid outlet channel 600 and the cavity 700 can also prevent the pressure in the cavity 700 from being too high, which may damage the connection stability between the housing assembly 10 and the liquid outlet assembly 20.

[0052] In an exemplary embodiment, referring to Figures 3 and 6 to 8 , there are multiple liquid outlet channels 600 , each of which is disposed around the raised portion 23 . Since the raised portion 23 is disposed opposite the liquid outlet 101 , liquid can evenly enter each liquid outlet channel 600 after elastic deformation of the driven raised portion 23 , enabling uniform liquid discharge from the subsequent liquid discharge device. There are multiple liquid distribution tanks 200 , each of which is connected to at least one liquid distribution tank 200 .

[0053] In an exemplary embodiment, referring to Figures 6 and 7 , the side of the raised portion 23 facing the liquid outlet 101 includes a guide surface 231. The guide surface 231 is configured to elastically deform with the raised portion 23 to guide the liquid into the liquid outlet channel 600. The provision of the guide surface 231 facilitates the entry of the liquid into the liquid outlet channel 600 and provides a certain degree of guidance for the liquid flow.

[0054] In an exemplary embodiment, as shown in FIG6 , the guide surface 231 is a spherical cap. This allows a line seal to be formed between the protrusion 23 and the housing assembly 10. At this time, the top of the protrusion 23 is located in the liquid inlet channel 100 and seals the liquid outlet 101. In the embodiment of the present disclosure, the housing assembly 10 is provided with a receiving groove 800. The remaining portion of the protrusion 23 is located in the receiving groove 800, so that through the provision of the receiving groove 800, it plays a limiting and guiding role during the elastic deformation and reset process of the protrusion 23, ensuring that the elastic deformation and reset can achieve the expected results, thereby ensuring that the liquid outlet 101 and the liquid outlet channel 600 can be connected after the elastic deformation of the protrusion 23, and ensuring that the liquid outlet 101 can be sealed after the protrusion 23 is reset. In addition, in some exemplary embodiments, the protrusion 23 can also form a line seal with the notch formed by the receiving groove 800 in the housing assembly 10 to prevent residual liquid in the receiving groove 800 from entering the liquid outlet channel 600.

[0055] In another exemplary embodiment, as shown in FIG7 , the raised portion 23 includes a circumferential wall 232 and a connecting wall 233 . The circumferential wall 232 bends toward the connecting wall 233 and connects to the circumferential outer side of the connecting wall 233 to form a guide surface 231 on the side of the circumferential wall 232 facing away from the connecting wall 233 . This allows an end-face seal to be formed between the raised portion 23 and the housing assembly 10 . In this case, the raised portion 23 is entirely located outside the liquid inlet channel 100 and seals the liquid outlet 101 . In the disclosed embodiment, the housing assembly 10 is provided with a receiving groove 800 . The raised portion 23 can be entirely located within the receiving groove 800 . The provision of the receiving groove 800 allows the raised portion 23 to serve as a limiting guide during the elastic deformation and reset process, ensuring that the elastic deformation and reset are achieved as expected, thereby ensuring that the liquid outlet 101 and the liquid outlet channel 600 are connected after the elastic deformation of the raised portion 23 , and ensuring that the liquid outlet 101 is sealed after the raised portion 23 is reset. Liquid acts on the connecting wall 233, causing the circumferential wall 232 to bend toward the connecting wall 233 so that the guide surface 231 faces the liquid outlet 101, thereby guiding the liquid to the liquid outlet channel 600. In addition to line sealing and end face sealing, the raised portion 23 can also be sealed by other sealing methods.

[0056] As shown in Figure 7, the circumferential wall 232 and the connecting wall 233 can be combined to form a groove 900, which is arranged opposite the liquid outlet 101. The groove 900 is arranged opposite the liquid outlet 101. The provision of the groove 900 can thus locate the position where the liquid acts on the protrusion 23, facilitating the elastic deformation of the protrusion 23 as desired. This allows for synchronous elastic deformation at each position on the circumferential wall 232, allowing fluid to enter multiple liquid outlet channels 600 simultaneously, thereby improving the liquid discharge efficiency of the liquid discharge device.

[0057] In an exemplary embodiment, referring to FIG. 3 and FIG. 8 , the liquid outlet channel 600 at least partially deviates from the radial extension of the protrusion 23 , so that the liquid outlet channel 600 can accommodate more residual liquid, further preventing the residual liquid from being discharged from the liquid outlet hole 300 .

[0058] In an exemplary embodiment, please refer to Figures 1, 2, 4 to 8 together, the housing assembly 10 includes a face cover 11, a rear shell 12, an inner frame 13, a ball head 14, a ball head sleeve 15 and a nut 16. The face cover 11 and the rear shell 12 together form an installation space, the inner frame 13 and the liquid outlet assembly 20 are installed in the installation space, the inner frame 13 is connected to the rear shell 12, and can abut the liquid outlet assembly 20 against the face cover 11, so that the inner frame 13 and the face cover 11 can clamp the liquid outlet assembly 20. The liquid separation tank 200 is arranged on the inner frame 13. The descaling component 30 is arranged on the inner frame 13 and is partially located in the liquid separation tank 200. The mounting hole 500 is arranged on the face cover 11. The inner frame 13 and the main body 22 together form a liquid outlet channel 600.

[0059] The liquid inlet channel 100 passes through the ball head 14 and extends to the inner frame 13, forming a liquid outlet 101 on the inner frame 13. The nut 16 is threadedly connected to the inner frame 13 to press the ball head 14 against the inner frame 13 through the ball head sleeve 15 to limit the movement of the ball head 14 relative to the inner frame 13. In addition, the ball head 14 and the ball head sleeve 15 are in contact with each other on an arc surface to facilitate the rotation of the ball head 14 relative to the inner frame 13 to adjust the orientation of the cover 11 and thus adjust the liquid discharge direction. In order to reduce the wear of the ball head 14 when it rotates relative to the inner frame 13, a gasket 17 is provided between the ball head 14 and the inner frame 13. In addition, a seal 18 is provided between the gasket 17, the inner frame 13 and the ball head 14 to prevent liquid from being discharged from between the inner frame 13 and the ball head 14. In order to save water resources, a limiting flow plate 19 is also provided in the liquid inlet channel 100 to keep the liquid discharge volume of the liquid discharge device constant and save liquid consumption.
