[0036] After using the existing liquid outlet device, residual liquid is likely to form scale at the liquid outlet, blocking the liquid outlet and affecting the liquid discharge of the liquid outlet device. In order to remove scale, the liquid outlet device is often provided with a descaling component (such as a descaling needle, etc.) so that the descaling component can pass through the liquid outlet to achieve descaling. In order to ensure the coaxiality between the descaling component and the liquid outlet, it is necessary to improve the structural strength of the liquid outlet device to avoid structural deformation during use, which may cause the descaling component to be unable to pass through the liquid outlet; and it is also necessary to reduce the assembly tolerance of the liquid outlet device to ensure that the descaling component can pass through the liquid outlet smoothly, thereby increasing the manufacturing cost to ensure the coaxiality between the descaling component and the liquid outlet.

[0037] The embodiments of the present application provide a liquid discharge device and a liquid discharge system. This liquid discharge system can be installed in various environments, such as companies, schools, homes, and factories, to clean items to be washed, thereby improving and enhancing people's quality of life and health. The liquid discharge device can be, but is not limited to, a faucet, a showerhead, or a spray gun. To facilitate the description of the technical solution of this application, the following description uses a showerhead as an example.

[0038] The liquid outlet system provided in the embodiment of the present application will now be described in conjunction with Figures 1 to 6. The liquid outlet system includes a liquid outlet device and a liquid inlet component.

[0039] The liquid outlet device includes a housing assembly 10 and a descaling component 20. The housing assembly 10 is provided with a liquid outlet 100. The housing assembly 10 has an oral wall 11 surrounding the liquid outlet 100. The descaling component 20 can be movably mounted on the housing assembly 10 and corresponds to the liquid outlet 100. The descaling component 20 is configured to be able to move relative to the housing assembly 10 so as to pass through or reset from the liquid outlet 100, and can encounter obstruction from the oral wall 11 in the process of passing through or resetting from the liquid outlet 100 and be deformed so as to pass through or reset from the liquid outlet 100. In this way, when the coaxiality between the descaling component 20 and the liquid outlet 100 is good, the descaling component 20 can pass through the liquid outlet 100 directly; when the coaxiality between the descaling component 20 and the liquid outlet 100 is poor, the descaling component 20 can be deformed under the obstruction of the oral wall 11 so as to pass through or reset from the liquid outlet 100.

[0040] The liquid inlet assembly is connected to the liquid outlet 100 and is configured to provide liquid to the liquid outlet 100. The liquid inlet assembly may be, but is not limited to, a manually or electrically controlled valve structure. Opening or closing the liquid inlet assembly connects or disconnects the liquid outlet 100 from the liquid source. The liquid includes, but is not limited to, clean or purified water from a municipal water network.

[0041] In summary, the implementation of the embodiments of the present application will have the following beneficial effects: the liquid outlet device of the above-mentioned scheme is applied to the liquid outlet system. In addition to making the liquid outlet system have excellent cleaning performance, it can also reduce the need to improve structural strength and reduce assembly tolerances, thereby reducing manufacturing costs. Specifically, the liquid outlet device includes a housing assembly 10 provided with a liquid outlet 100 and a descaling component 20. The housing assembly 10 has an orifice wall 11 that surrounds the liquid outlet 100. The descaling component 20 can be movably mounted on the housing assembly 10 and corresponds to the liquid outlet 100. The descaling component 20 can move relative to the housing assembly 10 to pass through or reset from the liquid outlet 100, and can encounter obstruction from the orifice wall 11 in the process of passing through or reset from the liquid outlet 100 and be deformed so as to pass through or reset from the liquid outlet 100. By leveraging its deformability, the descaling element 20 ensures it exits the liquid outlet 100, reducing the manufacturing costs associated with increasing the structural strength of the liquid outlet device and reducing assembly tolerances to ensure coaxiality between the descaling element 20 and the liquid outlet 100. Passing through the liquid outlet 100, the descaling element 20 removes scale from the outlet 100, preventing any residual scale. Furthermore, the descaling element 20 is relatively soft after exiting the liquid outlet 100, eliminating the risk of scratches or punctures.

[0042] In an exemplary embodiment, referring to Figures 4 and 6 , the radial dimension of the descaling member 20 is equal to or greater than the radial dimension of the liquid outlet 100. This allows the descaling member 20 to pass through the liquid outlet 100 directly or through deformation, making contact with the entire circumference of the outlet wall 11, ensuring a descaling effect on the outlet wall 11. Furthermore, after passing through the liquid outlet 100, the descaling member 20 can seal the liquid outlet 100, thereby closing the liquid outlet 100. The radial dimension of the liquid outlet 100 is the minimum radial dimension of the liquid outlet 100.

[0043] In an exemplary embodiment, as shown in Figure 12, the radial dimension of the descaling member 20 is smaller than the radial dimension of the liquid outlet 100, so that after the descaling member 20 passes through the liquid outlet 100 directly or through deformation, there is a gap between it and the mouth wall 11. At this time, since the descaling member 20 can partially fill the liquid outlet 100, the liquid outlet area of ​​the liquid outlet 100 is reduced, thereby accelerating the liquid outlet speed. The increase in the liquid outlet speed accelerates the flow speed of the liquid relative to the mouth wall 11, thereby increasing the liquid flushing against the mouth wall 11, which is beneficial to improving the descaling effect of the mouth wall 11 and having a pressurizing effect. Moreover, since the descaling member 20 can partially fill the liquid outlet 100, in addition to increasing the liquid outlet speed, it can also change the liquid outlet direction and / or liquid outlet shape. In addition, in some exemplary embodiments, a diversion structure (diversion groove, diversion protrusion, etc.) can also be provided on the mouth wall 11 and / or the descaling member 20 to change the liquid outlet direction and / or liquid outlet shape. The radial dimension of the liquid outlet 100 is the minimum radial dimension of the liquid outlet 100. When the descaling element 20 is not coaxial with the liquid outlet 100, deformation of the descaling element 20 is achieved through contact with the mouth wall 11, ensuring a close fit between the descaling element 20 and the mouth wall 11 and improving the descaling effect. Furthermore, deformation of the descaling element 20 due to contact with the mouth wall 11 can further increase the contact area between the descaling element 20 and the mouth wall 11, further improving the descaling effect.

[0044] In an exemplary embodiment, as shown in FIG7 , the housing assembly 10 includes a body 12 and multiple liquid outlets 13. The multiple liquid outlets 13 are exposed on the body 12, and the liquid outlet 13 is provided with at least one liquid outlet 100. The liquid outlet 13 can be provided with a single liquid outlet 100 and a corresponding descaling member 20, so that the descaling member 20 can perform descaling on the liquid outlet 100. The liquid outlet 13 can also be provided with multiple liquid outlets 100 and multiple descaling members 20, with the multiple descaling members 20 corresponding one-to-one with the multiple liquid outlets 100 to perform descaling.

[0045] In an exemplary embodiment, referring to Figures 2, 3, and 5, the liquid outlet device includes a drive assembly 30 configured to drive the descaling component 20 to move relative to the housing assembly 10. The drive assembly 30 facilitates driving the descaling component 20. When there are multiple descaling components 20, the drive assembly 30 can synchronously drive the multiple descaling components 20, achieving synchronous descaling of multiple liquid outlets 100 and improving the efficiency of the descaling process. Furthermore, in some exemplary embodiments, the drive assembly 30 can also implement step-by-step control of different descaling components 20 to achieve different descaling effects.

[0046] In an exemplary embodiment, referring to Figures 2, 3, and 5, the drive assembly 30 includes a pressing member 31, a frame 32, and a reset member 33. The pressing member 31 is connected to the frame 32 and is at least partially exposed from the housing assembly 10 to facilitate manual pressure control. At least one of the pressing member 31 and the frame 32 is slidably connected to the housing assembly 10 to ensure the stability of the pressing member 31 and the frame 32 relative to the housing assembly 10. In the embodiment herein, the pressing member 31 and the frame 32 are both slidably connected to the housing assembly 10, further increasing the connection area between the pressing member 31 and the frame 32 and the housing assembly 10, thereby further improving sliding stability. The pressing member 31 and the frame 32 can be detachably connected via a screw 40. In addition, in some exemplary embodiments, the pressing member 31 and the frame 32 can also be detachably connected via a snap-fit, plug-in, or other method. In other exemplary embodiments, the pressing member 31 and the frame 32 can also be integrally formed.

[0047] The descaling component 20 is provided on the frame 32, and the descaling component 20 can be connected to the frame 32 as a whole by embedding, injection molding, secondary injection molding or integral molding. In some exemplary embodiments, as shown in Figures 4, 6, 9 and 13, the descaling component 20 is provided on the surface of the frame 32 by an injection molding process. In other exemplary embodiments, a mounting hole 300 is provided on the frame 32, and the descaling component 20 is filled in the mounting hole 300 by an injection molding process and partially protrudes from the frame 32. In this way, the setting of the mounting hole 300 can increase the connection area between the descaling component 20 and the frame 32, thereby improving the connection stability. As shown in Figures 4 and 6, the mounting hole 300 is a through hole. As shown in Figures 9 and 13, the mounting hole 300 is a countersunk hole.

[0048] The pressing member 31 is configured to drive the descaling member 20 to move relative to the outer shell assembly 10 through the frame 32 under the drive of an external force, so that the descaling member 20 can pass through the liquid outlet 100 directly or through deformation. The reset member 33 is configured to be able to drive the descaling member 20 to reset after the external force is removed. In the embodiment of the present application, the reset member 33 is a spring. The pressing member 31 drives the frame 32 under the action of hand pressure. At the same time, the pressing member 31 and / or the frame 32 can compress the reset member 33 to the outer shell assembly 10. When the hand leaves the pressing member 31 and the external force is removed, the reset member 33 restores its shape and can drive the descaling member 20 to reset. The reset member 33 can also be an elastic structure made of an elastomeric material. In addition, in some exemplary embodiments, the reset member 33 may also be a component such as a magnet or an electromagnet that can form a magnetic field, and the pressing member 31 and / or the frame 32 have a structure that can be affected by the magnetic field. After the external force is removed, the pressing member 31 and the frame 32 can move relative to the housing assembly 10 under the action of the magnetic field to reset the descaling member 20.

[0049] It can be understood that in other embodiments, the drive assembly includes a slider and a frame. The descaling member is disposed on the frame and is slidably connected to the housing assembly via the frame. The slider is provided with an inclined surface. The slider is capable of moving relative to the housing assembly, and the frame is capable of sliding along the inclined surface. Under the action of the inclined surface, the slider slides relative to the housing assembly to drive the descaling member to pass through the liquid outlet directly or by deformation or to reposition.

[0050] In an exemplary embodiment, please refer to Figures 2, 3 and 5 together, the shell assembly 10 includes a face shell 14 and a rear shell 15, and the frame 32 is installed in the space enclosed by the face shell 14 and the rear shell 15, and can slide relative to the shell assembly 10. There are multiple liquid outlets 100 and they are evenly arranged on the face shell 14. The face shell 14 and the rear shell 15 can be connected by threaded connection, snap connection or plug-in connection. In order to improve the sealing performance, a sealing structure 16 is provided between the face shell 14 and the rear shell 15. In addition, in some exemplary embodiments, the face shell 14 and the rear shell 15 can also be made into one piece. The shell assembly 10 is also provided with a flow channel 200, which is connected to the liquid outlet 100. The shell assembly 10 also includes a liquid separator 17 to allow the liquid in the flow channel 200 to flow evenly to each liquid outlet 100.

[0051] In an exemplary embodiment, the housing assembly is further provided with a flow channel, and the drive assembly is further configured to drive the descaling component to reset when the liquid pressure in the flow channel exceeds a preset value, so that the liquid outlet is completely open and connected to the flow channel, and is capable of resisting the liquid pressure less than or equal to the preset value and driving the descaling component to pass through the liquid outlet to seal the liquid outlet or partially fill the liquid outlet.

[0052] The preset value can be set to satisfy that under certain conditions the liquid outlet is completely open, and under certain conditions the liquid outlet is sealed or partially open. In the embodiment of the present application, the preset value can be set to be less than the liquid pressure when the liquid inlet component is opened to provide liquid to the flow channel and greater than the liquid pressure generated by the liquid remaining in the flow channel after the liquid inlet component is closed. That is, after the liquid outlet device is opened to discharge liquid, the liquid drives the drive component to drive the descaling component to reset and move away from the liquid outlet so that the liquid outlet is completely open and connected to the flow channel. After the liquid outlet device is closed to discharge liquid, the drive component can drive the descaling component to pass through the liquid outlet directly or through deformation. In the embodiment of the present application, the radial dimension of the descaling component is greater than or equal to the radial dimension of the liquid outlet, so that the descaling component can seal the liquid outlet after passing through the liquid outlet, achieving the effect of stopping the liquid discharge after the liquid outlet device is closed to discharge liquid, avoiding the liquid remaining in the flow channel from being discharged from the liquid outlet, and improving the user experience.

[0053] In an exemplary embodiment, please refer to Figures 3 and 5 together, a seal 50 is provided between the pressing member 31 and the outer shell assembly 10 and / or between the frame 32 and the outer shell assembly 10 to ensure the sealing between the movable parts of the liquid outlet device (pressing member 31 and frame 32) and the frame 32 to prevent liquid from flowing out from between the movable parts and the frame 32.

[0054] In an exemplary embodiment, please refer to Figures 4, 6 and 12, the descaling member 20 has a columnar structure or a conical structure to facilitate movement into the liquid outlet 100 and out of the liquid outlet 100. In some exemplary embodiments, the descaling member 20 has a columnar structure, and the end of the descaling member 20 close to the liquid outlet 100 has a guide portion 21 to facilitate the movement of the descaling member 20 into the liquid outlet 100 after contacting the mouth wall 11, so as to avoid excessive resistance during the movement of the descaling member 20, resulting in abnormal deformation and inability to pass through the liquid outlet 100. In the embodiment of the present application, the guide portion 21 has a spherical crown surface. The descaling member 20 is made of an elastomeric material, so that the overall material of the descaling member 20 is the same, which is convenient for one-time molding preparation. Columnar structures include but are not limited to cylindrical structures, truncated cone structures, frustum structures or prismatic structures.

[0055] In other exemplary embodiments, the descaling member 20 is a conical structure having a pointed end, which facilitates the introduction of the descaling member 20 into the liquid outlet 100. The conical structure includes but is not limited to a conical structure or a pyramidal structure.

[0056] In an exemplary embodiment, as shown in FIG8 , the descaling member 20 includes a core 22 and a coating 23. The coating 23 at least coats the core 22 in the circumferential direction. The coating 23 is made of an elastomeric material or sponge, and the radial dimension of the core 22 is smaller than the radial dimension of the liquid outlet 100, so that when the descaling member 20 enters the liquid outlet 100, the coating 23 can be deformed after contacting the mouth wall 11, so as to reduce the radial dimension of the descaling member 20 and facilitate the descaling member 20 to pass through the liquid outlet 100. If the coating 23 is made of an elastomeric material, the deformation is elastic deformation, and the coating 23 can be restored to its original shape after being separated from the mouth wall 11. If the coating 23 is made of a sponge, the deformation is the deformation caused by the sponge adapting to the shape of the mouth wall 11, and the deformation cannot be completely restored to its original shape after the coating 23 is separated from the mouth wall 11.

[0057] The core 22 can be made of a hard material to enhance the strength of the descaling element 20 and ensure that the descaling element 20 maintains its general shape even when the coating layer 23 encounters excessive frictional resistance from the mouth wall 11, allowing it to pass smoothly through the liquid outlet 100. In some exemplary embodiments, the coating layer 23 can also simultaneously cover the end of the core 22 closest to the liquid outlet 100 to avoid the coating layer 23 only covering the circumference of the core 22. When the coating layer 23 encounters resistance, the tangential force generated between the coating layer 23 and the core 22 can easily cause cracking between the coating layer 23 and the core 22. The core 22 can also be made of an elastomeric material to enhance the elastic deformation capability of the descaling element 20.

[0058] In an exemplary embodiment, as shown in Figure 9 , the descaling member 20 includes a plurality of bristles 24 extending axially along the liquid outlet 100. Upon contact with the outlet wall 11, the bristles 24 deform and bend toward the axis of the liquid outlet 100 to conform to the shape of the liquid outlet 100, facilitating the descaling member 20's passage through the liquid outlet 100. The spacing between adjacent bristles 24 increases the deformation range of the bristles 24, allowing them to adapt to the various shapes of the liquid outlet 100.

[0059] In an exemplary embodiment, as shown in FIG13 , the descaling member 20 includes a plurality of elastic members 26 extending axially along the liquid outlet 100. Upon contact with the outlet wall 11, the elastic members 26 deform and bend toward the axis of the liquid outlet 100 to conform to the shape of the liquid outlet 100, facilitating the descaling member 20's passage through the liquid outlet 100. Adjacent elastic members 26 are spaced apart to increase their deformation range, adapting to various liquid outlet 100 shapes. The elastic members 26 can be made of an elastomeric material.

[0060] In an exemplary embodiment, referring to Figures 10 and 11 , the descaling member 20 includes a support portion 25 and a plurality of bristles 24. The bristles 24 are arranged circumferentially around the support portion 25, and the radial dimension of the support portion 25 is smaller than the radial dimension of the liquid outlet 100. When the descaling member 20 enters the liquid outlet 100, the bristles 24 can deform upon contact with the outlet wall 11 to adapt to the shape of the liquid outlet 100 (in Figure 10, the liquid outlet 100 is a tapered hole; in Figure 11, the liquid outlet 100 is a stepped hole), thereby facilitating the descaling member 20 to pass through the liquid outlet 100. The support portion 25 can be made of a hard material to enhance the strength of the descaling member 20 and ensure that the descaling member 20 can still pass through the liquid outlet 100 smoothly even when the bristles 24 encounter excessive frictional resistance from the outlet wall 11. In some exemplary embodiments, the bristles 24 can also be arranged at one end of the support portion 25 near the liquid outlet 100. In the embodiment of the present application, the bristles 24 extend perpendicularly to the axial direction of the support portion 25. It is understood that in other embodiments, the bristles 24 may extend at an angle other than 90° to the axial direction of the support portion 25. Furthermore, in some exemplary embodiments, the bristles 24 may extend in at least two different directions. The support portion 25 may also be made of an elastomeric material to enhance the elastic deformation capability of the descaling element 20.
