[0087] Existing liquid dispensing devices typically use dispensing holes on the water outlet section to achieve different dispensing effects. However, the small diameter of the dispensing holes can lead to clogging, scaling, and difficulty in cleaning.

[0088] This disclosure provides a liquid dispensing device and system. The system can be installed in various environments such as companies, schools, homes, and factories to clean items, thereby improving people's quality of life and health. The dispensing device can be, but is not limited to, a faucet, showerhead, or spray gun. For ease of description, a showerhead will be used as an example.

[0089] This disclosure provides a liquid dispensing system. The liquid dispensing system includes a liquid dispensing device.

[0090] Liquid dispensing device, including:

[0091] The main structure includes an inlet channel, an outlet chamber, and multiple outlet sections. The inlet channel communicates with the outlet chamber, and each outlet section has an outlet hole that communicates with the outlet chamber.

[0092] The movable component is movably installed in the liquid outlet chamber. The movable component is configured to move relative to the main structure and connect or separate from multiple liquid outlet sections.

[0093] In an exemplary embodiment, the main structure includes a rear cover mechanism and a front cover mechanism. The rear cover mechanism is provided with a liquid inlet channel. The front cover mechanism is mounted on the rear cover mechanism. The front cover mechanism is provided with a liquid outlet chamber and multiple liquid outlet sections, the liquid inlet channel communicating with the liquid outlet chamber, and the liquid outlet sections being provided with liquid outlet holes communicating with the liquid outlet chamber; and

[0094] The movable component is movably mounted in the liquid outlet chamber and is configured to move relative to the face shell mechanism, and to connect or separate from the plurality of liquid outlet sections.

[0095] The above-described liquid dispensing device, when applied to a liquid dispensing system, not only provides excellent cleaning performance but also reduces the likelihood of clogging and scaling at the dispensing orifices. Specifically, the device includes a rear cover mechanism with an inlet channel, a front shell mechanism mounted on the rear cover mechanism, and movable components. The front shell mechanism has a dispensing chamber and multiple dispensing sections. The inlet channel communicates with the dispensing chamber, and each dispensing section has a dispensing hole that communicates with the dispensing chamber. The movable components are designed to move relative to the front shell mechanism, connecting or separating from the multiple dispensing sections. This allows the dispensing sections to vibrate or elastically deform during connection and separation with the movable components, loosening scale formed on the walls of the dispensing orifices and facilitating its removal by the liquid flowing through them, thus preventing clogging.

[0096] The liquid dispensing system of this disclosure will be illustrated below by way of some exemplary embodiments.

[0097] Please combine them together Figure 6 , Figure 10 , Figure 11 , Figure 13 , Figure 16 , Figure 20 and Figures 2 to 5bThe following describes a liquid dispensing system according to an embodiment of the present disclosure. The liquid dispensing system includes a liquid dispensing device. The liquid dispensing device includes a rear cover mechanism 10, a front shell mechanism 20, and a movable component 30. The rear cover mechanism 10 is provided with a liquid inlet channel 100. The front shell mechanism 20 is mounted on the rear cover mechanism 10. The front shell mechanism 20 is provided with a liquid dispensing chamber 200 and a plurality of liquid dispensing sections 2122. The liquid inlet channel 100 communicates with the liquid dispensing chamber 200. The liquid dispensing sections 2122 are provided with liquid dispensing holes, including a first liquid dispensing hole 300 and a plurality of second liquid dispensing holes 400. The first liquid dispensing hole 300 and the plurality of second liquid dispensing holes 400 are all in communication with the liquid dispensing chamber 200. The second liquid dispensing holes 400 are arranged around the first liquid dispensing hole 300. The movable component 30 is movably installed in the liquid outlet chamber 200. When the movable component 30 is connected to the plurality of liquid outlet parts 2122, it can block the first liquid outlet 300. When the movable component 30 is separated from the plurality of liquid outlet parts 2122, it can open the first liquid outlet 300.

[0098] The liquid dispensing system also includes a liquid inlet assembly. The rear cover mechanism 10 is provided with a connection structure 1221 that connects to the liquid inlet assembly. The connection structure 1221 can be connected to the liquid inlet assembly via, but is not limited to, threaded connection, plug-in connection, snap-fit ​​connection, or welding. The liquid inlet assembly is configured to supply liquid to the liquid dispensing device. The liquid inlet assembly can 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 dispensing device from the liquid source. The liquid includes, but is not limited to, clean water or pure water from the municipal water network.

[0099] The above-described liquid dispensing device is applied to a liquid dispensing system. Besides providing excellent cleaning performance, it also reduces the likelihood of clogging and scaling at the dispensing holes and can meet the needs of some users who require a strong liquid dispensing impact. Specifically, the liquid dispensing device includes a rear cover mechanism 10 with an inlet channel 100, a faceplate mechanism 20 mounted on the rear cover mechanism 10, and a movable component 30. The faceplate mechanism 20 has a liquid dispensing chamber 200 and multiple dispensing sections 2122. The inlet channel 100 communicates with the liquid dispensing chamber 200. The dispensing sections 2122 have a first dispensing hole 300 and multiple second dispensing holes 400, both of which communicate with the liquid dispensing chamber 200. The second dispensing holes 400 are arranged around the first dispensing hole 300. The movable component 30 is configured to move relative to the faceplate mechanism 20. It connects to multiple liquid outlet sections 2122 to block the first liquid outlet 300, allowing liquid to exit only through the second liquid outlet 400, creating a fine, drizzling liquid flow. Alternatively, the movable component 30 can be configured to move relative to the faceplate mechanism 20 and separate from the multiple liquid outlet sections 2122, opening the first liquid outlet 300. This allows liquid to exit simultaneously from both the first and second liquid outlets 300, increasing the flow area of ​​the liquid outlet sections 2122, facilitating the removal of impurities from the liquid, reducing the likelihood of clogging the first and second liquid outlets 300 and 400, and enhancing the impact of the liquid flow. The movable component 30 is configured to move relative to the face shell mechanism 20 and connect or separate from multiple liquid outlets 2122. This allows the liquid outlets 2122 to vibrate or elastically deform during the connection and separation process with the movable component 30, thereby loosening the scale formed on the walls of the liquid outlet holes (first liquid outlet hole 300 and second liquid outlet hole 400) and making it easier for the liquid passing through the liquid outlet holes (first liquid outlet hole 300 and second liquid outlet hole 400) to be flushed away, thus preventing the liquid outlet holes (first liquid outlet hole 300 and second liquid outlet hole 400) from being blocked by scale.

[0100] In the exemplary embodiments, please refer to Figure 5b The radial dimension of the first outlet 300 is larger than that of the second outlet 400, resulting in a softer and finer flow of liquid from the second outlet 400 during the silk rain process. Meanwhile, the liquid flow rate from the first outlet 300 is greater, creating a stronger impact. Furthermore, the smaller radial dimension of the second outlet 400 makes it more susceptible to clogging by impurities. Even when the second outlet 400 is clogged, the first outlet 300 can still discharge liquid. In this case, the impurities clogging the second outlet 400 will be carried out by the liquid and discharged from the first outlet 300, which helps to remove impurities and restore the original flow pattern of the first outlet 300 and the multiple second outlets 400.

[0101] The first liquid outlet 300 and multiple second liquid outlets 400 can discharge liquid simultaneously, increasing the discharge area of ​​the liquid outlet section 2122. When the liquid inlet assembly stops supplying liquid to the liquid outlet device, the first liquid outlet 300 and multiple second liquid outlets 400 can discharge residual liquid simultaneously, which is beneficial for accelerating the discharge and drying of residual liquid and slowing down the formation of scale.

[0102] In an exemplary embodiment, such as Figure 5a As shown, during the process of the movable component 30 blocking the first liquid outlet 300, the liquid outlet portion 2122 can be driven to protrude to the side away from the movable component 30. This allows each second liquid outlet 400 to change its liquid outlet direction as the liquid outlet portion 2122 protrudes to the side away from the movable component 30, resulting in a relatively large distance between the liquid outlets of each second liquid outlet 400, preventing them from converging into a single stream, thus ensuring the soft and delicate characteristics of the drizzle. In this embodiment, the liquid outlet portion 2122 can be made of an elastomer material. Furthermore, after the movable component 30 blocks the first liquid outlet 300, the friction between the movable component 30 and the multiple liquid outlet portions 2122 can cause the multiple liquid outlet portions 2122 to bulge and indent until the driving force on the movable component 30 exceeds the friction force, thus separating them from the multiple liquid outlet portions 2122. During the aforementioned protrusion and depression deformation process, the scale formed on the wall of the liquid outlet (first liquid outlet 300 and second liquid outlet 400) can be further loosened, making it easier to be washed away by the liquid passing through the liquid outlet (first liquid outlet 300 and second liquid outlet 400), thus preventing the liquid outlet (first liquid outlet 300 and second liquid outlet 400) from being blocked by scale.

[0103] like Figure 3 As shown, the liquid outlet direction of the first liquid outlet 300 intersects with the liquid outlet direction of the second liquid outlet 400, and the angle α between the liquid outlet direction of the first liquid outlet 300 and the liquid outlet direction of the second liquid outlet 400 is less than or equal to 10°. This allows the liquid discharged from the first liquid outlet 300 and the liquid discharged from the second liquid outlet 400 to converge into a single liquid flow, forming a new liquid outlet pattern and further enhancing the impact of the liquid outlet. In this embodiment, the liquid discharge direction of each second liquid outlet 400 converges towards the liquid discharge direction of the first liquid outlet 300 located at the center of each second liquid outlet 400, forming a stream of liquid discharge. During the process of the movable component 30 blocking the first liquid outlet 300, the liquid discharge part 2122 can protrude to the side away from the movable component 30, thereby changing the liquid discharge direction of each second liquid outlet 400 from converging towards the liquid discharge direction of the first liquid outlet 300 to parallel, or even further deflecting away from the liquid discharge direction of the first liquid outlet 300, to avoid the convergence of liquid discharge between each second liquid outlet 400 when the filamentous liquid is discharged, thus ensuring the filamentous liquid discharge effect.

[0104] In the exemplary embodiments, please refer to Figure 4and Figure 7 The axis of the first liquid outlet 300 is parallel to the axis of the second liquid outlet 400, and the distance between the axes of the first liquid outlet 300 and the second liquid outlet 400 is less than or equal to 1 mm. The movable component 30 moves relative to the face shell mechanism 20, opening the first liquid outlet 300. The first liquid outlet 300 and the second liquid outlet 400 can discharge liquid simultaneously. The distance between the axes of the first liquid outlet 300 and the second liquid outlet 400 is less than or equal to 1 mm, so that the liquid discharged from the first liquid outlet 300 and the liquid discharged from the second liquid outlet 400 are close enough to form a Bernoulli effect. The resulting tension can cause the liquid discharged from the first liquid outlet 300 and the liquid discharged from the second liquid outlet 400 to be adsorbed into a single liquid flow, forming a new liquid discharge pattern. This makes the liquid discharge shape of the liquid discharge device more uniform and regular, ensuring the uniformity of the liquid discharge direction.

[0105] In an exemplary embodiment, the diameter of the first liquid outlet 300 can be approximately 0.5 mm to 1.5 mm. For example, the diameter of the first liquid outlet 300 can be approximately 1 mm.

[0106] In an exemplary embodiment, the diameter of the second liquid outlet 400 can be approximately 0.2 mm to 0.6 mm. For example, the diameter of the second liquid outlet 400 can be approximately 0.4 mm.

[0107] In the exemplary embodiments, please refer to Figure 11 , Figure 17 and Figure 2The active component 30 includes a body 31 and multiple sealing structures 32. The sealing structures 32 are disposed on the body 31 and correspond one-to-one with multiple liquid outlets 2122. The body 31 is slidably connected to the faceplate mechanism 20. The sealing structures 32 can move closer to the corresponding liquid outlet 2122 as the body 31 moves and connect to the corresponding liquid outlet 2122 to seal the corresponding first liquid outlet 300; or they can reset as the body 31, opening the first liquid outlet 300. Thus, by driving the body 31, the multiple sealing structures 32 can simultaneously seal the corresponding first liquid outlet 300, allowing only the second liquid outlet 400 to discharge liquid; or the multiple sealing structures 32 can simultaneously open the corresponding first liquid outlet 300, allowing the first liquid outlet 300 and the second liquid outlet 400 to discharge liquid simultaneously, ensuring consistent liquid outlet switching. Furthermore, the sealing structure 32 only changes the connection state between the corresponding first liquid outlet 300 and the liquid outlet chamber 200 to achieve the switching of liquid outlet mode (silky rain liquid outlet and impact liquid outlet), while the liquid outlet position (the area range where each first liquid outlet 300 and the corresponding second liquid outlet 400 are located) does not change. This ensures that the switching of liquid outlet mode does not affect the liquid outlet of the full shell mechanism 20 of the liquid outlet device, and avoids the liquid outlet positions of different liquid outlet modes being dispersed in different liquid outlet areas. As a result, the liquid outlet device in this embodiment has a large liquid outlet area, ensuring that a better showering effect can be achieved before and after the liquid outlet mode is switched.

[0108] In the exemplary embodiments, please refer to Figure 7 , Figure 18 and Figure 2 The sealing structure 32 can be at least partially inserted into the corresponding first liquid outlet 300 to seal the corresponding first liquid outlet 300. In this way, the insertion action of the sealing structure 32 can remove the scale formed in the first liquid outlet 300, further improving the descaling effect. The fact that the sealing structure 32 can be at least partially inserted into the corresponding first liquid outlet 300 allows the friction between the sealing structure 32 and the corresponding liquid outlet 2122 to cause the corresponding liquid outlet 2122 to bulge or concave.

[0109] In the exemplary embodiments, please continue to refer to Figure 7 , Figure 18 and Figure 7The sealing structure 32 includes an insertion part 321 and a connecting part 322. The insertion part 321 is connected to the body 31 through the connecting part 322. Multiple protrusions 3221 are provided on the outer circumferential side of the connecting part 3222. A guide groove 500 is provided between adjacent protrusions 3221. The insertion part 321 can be inserted into a corresponding first liquid outlet 300, and the multiple protrusions 3221 can abut against a corresponding liquid outlet 2122, allowing the multiple guide grooves 500 to communicate one-to-one with the corresponding multiple second liquid outlets 400. Thus, the insertion action of the insertion part 321 can remove scale formed in the first liquid outlet 300, further improving the descaling effect. The insertion part 321 can be clearance-fitted with the wall of the first liquid outlet 300. The insertion part 321 can also be interference-fitted with the wall of the first liquid outlet 300. In this case, the liquid outlet part 2122 can be made of an elastomer material so that it can elastically deform during the insertion of the insertion part 321 into the first liquid outlet 300, facilitating the passage of the insertion part 321 through the first liquid outlet 300. The aforementioned interference fit can further improve the removal effect on the scale formed in the first liquid outlet 300. Utilizing the aforementioned interference fit and / or the driving effect of the connecting part 322 on the liquid outlet part 2122, the liquid outlet part 2122 can protrude to the side away from the movable component 30, thereby changing the liquid outlet direction of the second liquid outlet 400. The guide groove 500 can guide the liquid more smoothly to the second liquid outlet 400 and prevent the connecting part 322 from interfering with the liquid entering the second liquid outlet 400. The protrusion 3221 abutting against the corresponding liquid outlet 2122 can be a flat surface, an inclined surface, or an arc surface, etc., so as to change the shape of the liquid outlet 2122 protruding away from the movable component 30. Utilizing the above-mentioned interference fit, the friction between the insertion part 321 and the corresponding liquid outlet 2122 can also cause the corresponding liquid outlet 2122 to bulge or indent.

[0110] In the exemplary embodiments, please refer to Figure 11 , Figure 14 , Figure 21 and Figure 11 The main body 31 is provided with a guide member 311, which engages with the shell mechanism 20 to guide and restrict the movement direction of the movable component 30. This guide member 311 further increases the connection area between the main body 31 and the shell mechanism 20, improving connection stability. Furthermore, the guiding engagement between the guide member 311 and the shell mechanism 20 ensures the movement accuracy of the movable component 30, thereby guaranteeing the sealing accuracy between the movable component 30 and the multiple first liquid outlet holes 300.

[0111] In an exemplary embodiment, such as Figure 21 and Figure 7As shown, the rear cover mechanism 10 has a boss 11, and the front shell mechanism 20 is provided with a guide hole 600, through which a guide member 311 passes. The front shell mechanism 20 can rotate relative to the rear cover mechanism 10 to drive the guide member 311 to slide along the boss 11, so that the body 31 approaches the plurality of liquid outlets 2122.

[0112] In this embodiment, the faceplate mechanism 20 is rotatable relative to the rear cover mechanism 10 to drive the guide member 311 to slide along the boss 11, causing the body 31 to approach the multiple liquid outlets 2122. This allows the sealing structure 32 to move with the body 31 towards the corresponding liquid outlet 2122 and block the corresponding first liquid outlet 300. The guide hole 600 allows the guide member 311 to contact the boss 11. As the guide member 311 slides along the boss 11, it can adjust the distance between the movable component 30 and the multiple liquid outlets 2122 according to the degree of protrusion of the boss 11 towards the faceplate mechanism 20, until the sealing structure 32 blocks the corresponding first liquid outlet 300, or until the sealing structure 32 blocks the corresponding first liquid outlet 300 and causes the liquid outlet 2122 to protrude away from the movable component 30. The extension direction of the boss 11 matches the rotation trajectory of the guide 311 to ensure that the guide 311 can always contact the boss 11 during the movement of the movable component 30 to the multiple liquid outlets 2122, thus ensuring the smooth movement of the movable component 30 to the multiple liquid outlets 2122.

[0113] In other embodiments, the movable component 30 can be driven by other driving structures to move relative to the faceplate mechanism 20, blocking or opening the first liquid outlet 300. For example, the movable component 30 can be driven by a pressing structure to move relative to the faceplate mechanism 20. Correspondingly, the faceplate mechanism 20 can be fixedly connected to the rear cover mechanism 10. The faceplate mechanism 20 can also be rotatably connected to the rear cover mechanism 10, driving the movable component 30 to move relative to the faceplate mechanism 20, either separately or jointly, with the pressing structure. In some embodiments, the movement of the movable component 30 relative to the faceplate mechanism 20 can also drive the faceplate mechanism 20 to move relative to the rear cover mechanism 10. In other embodiments, the movement of the movable component 30 relative to the faceplate mechanism 20 can also be hydraulically driven by the liquid entering the liquid outlet device. The movement of the movable component 30 relative to the faceplate mechanism 20 can also be driven by an electronic control mechanism disposed on the rear cover mechanism 10 or the faceplate mechanism 20.

[0114] In an exemplary embodiment, such as Figure 11 and Figure 9 As shown, the guide member 311 is provided with a guide surface 3111 that can guide and cooperate with the boss 11. In this way, the guide surface 3111 can ensure a smoother cooperation between the guide member 311 and the boss 11.

[0115] In the exemplary embodiments, please refer to Figure 11 , Figure 17 and Figure 8 One of the rear cover mechanism 10 and the front cover mechanism 20 is provided with a positioning component 40, and the other is provided with a positioning element. The positioning element is provided with a first positioning part 700 and a second positioning part 800. The first positioning part 700 and the second positioning part 800 are configured to cooperate with the positioning component 40 to perform positioning when the movable component 30 is connected to or separated from the multiple liquid outlets 2122.

[0116] In this embodiment of the present disclosure, the first positioning part 700 and the second positioning part 800 are configured to cooperate with the positioning component 40 to perform positioning when the first liquid outlet 300 is in a blocked or open state, respectively, so as to be able to sense whether the face shell mechanism 20 has moved to a preset position, thereby realizing the sensing of whether the first liquid outlet 300 corresponding to each preset position is in a blocked or open state.

[0117] The positioning assembly 40 includes a mounting component 41, an abutting component 42, and an elastic component 43. The mounting component 41 is disposed in either the rear cover mechanism 10 or the front cover mechanism 20, and has a mounting space. The abutting component 42 is partially located in the mounting space and can be slidably connected with the positioning component. The elastic component 43 is installed in the mounting space and can abut the abutting component 42 against the positioning component. The elastic component 43 ensures a tighter fit between the abutting component 42 and the positioning component, preventing gaps between them that could cause abnormal noise when the abutting component 42 slides against the positioning component.

[0118] In this embodiment, the first positioning part 700 and the second positioning part 800 are groove structures. The elastic member 43 can also make the abutting member 42 relatively stably positioned within the groove structure, improving the accuracy of position sensing. The elastic member 43 can be, but is not limited to, a metal spring or a plastic spring. In this embodiment, the mounting member 41 has a columnar structure and is disposed on the rear cover mechanism 10. The positioning member is disposed on the liquid distribution member 24.

[0119] In the exemplary embodiments, please refer to Figure 15 , Figure 22 and Figure 8The faceplate mechanism 20 includes a housing assembly 21 and a reset member 22. The housing assembly 21 can enclose a liquid outlet chamber 200 and can rotate relative to the rear cover mechanism 10. Multiple liquid outlets 2122 are disposed on the housing assembly 21. The reset member 22 is disposed on the housing assembly 21 or the rear cover mechanism 10. The reset member 22 is configured to generate a driving force for the movable component 30 to reset, so that multiple sealing structures 32 can reset with the body 31. In this embodiment, the reset member 22 is a helical spring. During the rotation of the housing assembly 21 relative to the rear cover mechanism 10, the guide member 311 slides along the boss 11 and causes the movable component 30 to move closer to the multiple liquid outlets 2122. The body 31 can compress the reset member 22, generate a driving force for the movable component 30 to reset, and make the guide member 311 fit tightly with the boss 11, ensuring the fitting accuracy of the guide member 311 and the boss 11. As the guide member 311 slides along the boss 11, and the outward protrusion of the boss 11 toward the faceplate mechanism 20 gradually decreases, the reset member 22 can drive the movable component 30 away from the multiple liquid outlets 2122, thereby resetting the movable component 30. Furthermore, in some exemplary embodiments, the reset member 22 can also be a magnetic element, generating a magnetic force on the movable component 30 to drive it to reset.

[0120] In the exemplary embodiments, please continue to refer to Figure 15 , Figure 22 and Figure 6 The reset element 22 is a helical spring, clamped between the movable component 30 and the housing component 21, and positioned and connected to at least one of the movable component 30 and the housing component 21 to ensure the stability of the reset element 22, thereby ensuring the directional accuracy of the reset driving force of the movable component 30. In this embodiment, the housing component 21 is provided with a connecting post 21211, and the movable component 30 is provided with a connecting groove 900 opposite to the connecting post 21211. One end of the reset element 22 is sleeved on the connecting post 21211, and the other end is received in the connecting groove 900. The body 31 can compress the reset element 22 when it is close to the multiple liquid outlets 2122 to generate the driving force for the reset of the movable component 30.

[0121] In the exemplary embodiments, please refer to Figure 14 , Figure 21 and Figure 6The faceplate mechanism 20 also includes a sealing component 23, which is disposed on the housing assembly 21 and sleeved on the guide member 311, providing a sliding seal with the guide member 311. This sealing component 23 ensures the sealing of the guide hole 600, preventing liquid from overflowing between the guide member 311 and the guide hole 600. Furthermore, the sealing component 23 increases the connection area between the guide member 311 and the housing assembly 21, improving the guiding stability between them. The sealing assembly 23 includes a cover 231 and a seal 232. The seal 232 is sleeved on the guide 311 and received in a receiving groove provided in the housing assembly 21. The seal 232 is located between the guide 311 and the housing assembly 21. The cover 231 is connected to the housing assembly 21 and sleeved on the guide 311. The cover 231 can seal the receiving groove to prevent the seal 232 from moving out of the receiving groove. The guide 311 passes through the seal 232 and extends out of the cover 231 to be able to contact the boss 11.

[0122] In the exemplary embodiments, please refer to Figure 11 , Figure 12 , Figure 14 , Figure 17 , Figure 19 , Figure 21 and Figure 2 The faceplate mechanism 20 also includes a liquid distribution component 24. The liquid distribution component 24 is disposed on the housing assembly 21 and together with the housing assembly 21 forms a first liquid distribution channel 1000 and a second liquid distribution channel 1100. The first liquid distribution channel 1000 and the second liquid distribution channel 1100 are respectively connected to the liquid outlet chamber 200. The liquid distribution component 24 is provided with a first channel hole 1001 communicating with the first liquid distribution channel 1000 and a second channel hole 1101 communicating with the second liquid distribution channel 1100.

[0123] During the rotation of the faceplate mechanism 20 relative to the rear cover mechanism 10, the liquid inlet channel 100 can communicate with the first flow channel hole 1001 to reduce the liquid flow rate entering the liquid outlet chamber 200 from the liquid inlet channel 100. The faceplate mechanism 20 can also drive the movable component 30 to connect with multiple liquid outlet sections 2122 to block the first liquid outlet hole 300; or the liquid inlet channel 100 can communicate with the second flow channel hole 1101 to increase the liquid flow rate. In this way, the faceplate mechanism 20 can drive the movable component 30 to separate from the multiple liquid outlet sections 2122, opening the first liquid outlet hole 300. Thus, when the first liquid outlet hole 300 is blocked, by reducing the liquid flow rate entering the liquid outlet chamber 200 from the liquid inlet channel 100, a softer and finer drizzle can be ensured, and excessive liquid pressure after the first liquid outlet hole 300 is blocked can be avoided, preventing damage to the liquid outlet section 2122 due to liquid pressure. When the first outlet 300 is open, increasing the liquid flow rate can ensure the liquid pressure, thereby ensuring the impact force of the liquid discharged from the first outlet 300 and the liquid discharged from the second outlet 400, and ensuring the impact sensation of the liquid discharge.

[0124] During the rotation of the faceplate mechanism 20 relative to the rear cover mechanism 10, the liquid inlet channel 100 can communicate with the first flow channel hole 1001 to reduce the liquid flow rate entering the liquid outlet chamber 200 from the liquid inlet channel 100, or communicate with the second flow channel hole 1101 to increase the liquid flow rate. Thus, by communicating the liquid inlet channel 100 with the first distribution channel 1000 and the second distribution channel 1100 respectively, the liquid flow rate can be easily controlled.

[0125] Please combine them together Figures 6 to 8 , Figure 11 , Figure 12 , Figure 14 , Figure 15 , Figure 17 , Figure 21 , Figure 22 and Figure 6The housing assembly 21 includes a faceplate 211, a liquid outlet component 212, and an inner frame 213. The faceplate 211 has multiple mounting holes. Multiple liquid outlet components 2122 are installed one-to-one with each mounting hole to ensure the stability of the position of the liquid outlet components 2122 relative to the faceplate 211. The liquid outlet component 212 is disposed on one side of the faceplate 211 and, together with the inner frame 213, forms a liquid outlet cavity 200. The inner frame 213 is connected to the faceplate 211 and fixes the liquid outlet component 212 to the faceplate 211. The liquid outlet component 212 includes a body portion 2121 and multiple liquid outlet components 2122 disposed on the body portion 2121. The liquid outlet component 2122 has a columnar structure, including a circumferential wall and a liquid outlet surface. The circumferential wall and the liquid outlet surface together form a liquid outlet groove 1200 communicating with the liquid outlet cavity 200. The first liquid outlet 300 and the second liquid outlet 400 are connected to the liquid outlet chamber 200 through the liquid outlet groove 1200. In this embodiment, the guide hole 600, the liquid distribution component 24, and the sealing assembly 23 are disposed on the inner frame 213. The connecting post 21211 is disposed on the body part 2121. The face cover 211 is provided with a driving protrusion 2111 to facilitate the rotation of the face shell mechanism 20 relative to the rear cover mechanism 10.

[0126] In the exemplary embodiments, please refer to Figure 9 , Figure 12 , Figure 14 , Figure 19 and Figures 23 to 28 The rear cover mechanism 10 includes a rear cover assembly 12 and an elastic component 13. The elastic component 13 is disposed on the rear cover assembly 12. The elastic component 13 has a through hole 1300, which communicates with the liquid inlet channel 100. The elastic component 13 elastically abuts against the liquid distributor 24. During the rotation of the face shell mechanism 20 relative to the rear cover mechanism 10, the elastic component 13 can slide relative to the liquid distributor 24, so that the through hole 1300 communicates with the first flow channel hole 1001 to reduce the liquid flow rate, or so that the through hole 1300 communicates with the second flow channel hole 1101 to increase the liquid flow rate. In this way, during the rotation of the face shell mechanism 20 relative to the rear cover mechanism 10, the elastic component 13 can always abut against the liquid distributor 24, preventing liquid from being discharged between the elastic component 13 and the liquid distributor 24, so that the liquid has a certain flow direction under the restriction of the elastic component 13 and the liquid distributor 24, ensuring that the liquid can stably flow into the first flow channel hole 1001 or the second flow channel hole 1101.

[0127] The elastic component 13 includes a flexible element 131 and an elastic element 132. The flexible element 131 can elastically abut against the liquid distribution component 24. The flexible element 131 can better fit the liquid distribution component 24 through its own deformation, thereby improving the sealing performance between the elastic component 13 and the liquid distribution component 24. The rear cover assembly 12 includes a rear cover 121, an inlet pipe 122, and a connector 123. The inlet pipe 122 is disposed on the rear cover 121 and connected to the connector 123. The inlet channel 100 passes through the inlet pipe 122 and the connector 123 in sequence. The connector 123 is provided with a mounting groove 1400 communicating with the inlet channel 100. The elastic element 132 is installed in the mounting groove 1400 and supported between the connector 123 and the flexible element 131, so as to further enhance the elastic abutment force of the flexible element 131 against the liquid distribution component 24, thereby further improving the sealing stability between the elastic component 13 and the liquid distribution component 24. A through hole 1300 passes through the flexible member 131 and communicates with the liquid inlet channel 100 via the mounting groove 1400. The flexible member 131 may be made of, but is not limited to, rubber. The elastic member 132 may be, but is not limited to, a metal spring or a plastic spring.

[0128] Please combine them together Figures 1 to 22 The liquid dispensing system provided in another embodiment of this disclosure will now be described. The structure of the liquid dispensing system in this embodiment is similar to... Figures 23 to 28 The embodiments shown are essentially the same, except that the insertion part 321 of the liquid dispensing system in this embodiment has a tip 3211 facing the corresponding first liquid dispensing hole 300. The movable component 30 is also configured to move relative to the faceplate mechanism 20, so that the tip 3211 is at least partially received in the corresponding first liquid dispensing hole 300, and the tip 3211 is spaced apart from the corresponding liquid dispensing portion 2122. This allows liquid to be discharged from the gap between the tip 3211 and the corresponding liquid dispensing portion 2122, and the flow area of ​​the gap is close to the flow area of ​​the second liquid dispensing hole 400. Utilizing the wall adhesion effect of the tip 3211, the liquid discharged from the gap can converge into a stream, similar in shape to the liquid discharged from the second liquid dispensing hole 400. This allows liquid to be discharged simultaneously from the gap and multiple second liquid dispensing holes 400, forming a large, fine stream of liquid.

[0129] In the exemplary embodiments, please continue to refer to Figure 27One of the rear cover mechanism 10 and the front cover mechanism 20 is provided with a positioning component 40, and the other is provided with a positioning element. The positioning element is provided with a first positioning part 700, a second positioning part 800, and a third positioning part 1500. The first positioning part 700, the second positioning part 800, and the third positioning part 1500 are configured to cooperate with the positioning component 40 to perform positioning when the movable component 30 is connected to or separated from the multiple liquid outlets 2122, or when the tip 3211 is at least partially received in the corresponding first liquid outlet hole 300, and the tip 3211 is spaced apart from the corresponding liquid outlet 2122 (the first liquid outlet hole 300 is in a partially obscured state). This allows the system to sense whether the front cover mechanism 20 has moved to a preset position, and to ensure that the first liquid outlet hole 300 corresponding to each preset position is in a blocked state (e.g., ...). Figure 23 As shown), open state (such as...) Figure 25 (as shown) or partially obscured (e.g.) Figure 23 (As shown) to perform perception.

[0130] The positioning assembly 40 includes a mounting component 41, an abutting component 42, and an elastic component 43. The mounting component 41 is disposed in either the rear cover mechanism 10 or the front cover mechanism 20, and has a mounting space. The abutting component 42 is partially located in the mounting space and can be slidably connected with the positioning component. The elastic component 43 is installed in the mounting space and can abut the abutting component 42 against the positioning component. The elastic component 43 ensures a tighter fit between the abutting component 42 and the positioning component, preventing gaps between them that could cause abnormal noise when the abutting component 42 slides against the positioning component.

[0131] In this embodiment, the first positioning part 700, the second positioning part 800, and the third positioning part 1500 are all groove structures. The elastic member 43 further enables the abutting member 42 to be relatively stably positioned within the groove structure, improving the accuracy of position sensing. The elastic member 43 can be, but is not limited to, a metal spring or a plastic spring. In this embodiment, the mounting member 41 has a columnar structure and is disposed on the rear cover mechanism 10. The positioning member is disposed on the liquid distribution member 24.

[0132] Please combine them together Figure 27 , Figure 28 and Figure 26After the insertion part 321 blocks the first liquid outlet 300, the friction between the insertion part 321 and the multiple liquid outlet parts 2122 can cause the multiple liquid outlet parts 2122 to bulge and indent until the driving force on the insertion part 321 is greater than the friction force, so as to separate from the multiple liquid outlet parts 2122. During the above-mentioned bulging and indenting deformation process, the scale formed on the hole wall of the liquid outlet (first liquid outlet 300 and second liquid outlet 400) can be further loosened, making it easier to be washed away by the liquid passing through the liquid outlet (first liquid outlet 300 and second liquid outlet 400), and preventing the liquid outlet (first liquid outlet 300 and second liquid outlet 400) from being blocked by scale.

[0133] In an exemplary embodiment, the movement of the movable component 30 relative to the faceplate mechanism 20 can also be hydraulically driven by the liquid entering the liquid outlet device. The movement of the movable component 30 relative to the faceplate mechanism 20 can also be driven by an electronically controlled mechanism disposed on the rear cover mechanism 10 or the faceplate mechanism 20.

[0134] In an exemplary embodiment, such as Figures 29 to 45 As shown, the liquid distribution component 24 can also be combined with the housing assembly 21 to form a third liquid distribution channel 1600. The third liquid distribution channel 1600 is connected to the liquid outlet chamber 200. The liquid distribution component 24 is provided with a third channel hole 1601 that is connected to the third liquid distribution channel 1600.

[0135] During the rotation of the faceplate mechanism 20 relative to the rear cover mechanism 10, the liquid inlet channel 100 can also communicate with the third channel hole 1601, so that the liquid flow rate entering the liquid outlet chamber 200 from the liquid inlet channel 100 is moderate, and the faceplate mechanism 20 can drive the movable component 30 so that the tip 3211 is at least partially received in the corresponding first liquid outlet hole 300, and the tip 3211 is spaced apart from the corresponding liquid outlet part 2122. In this way, when the first liquid outlet hole 300 is in a partially blocked state, by adjusting the liquid flow rate entering the liquid outlet chamber 200 from the liquid inlet channel 100, it is possible to ensure that the liquid output of Da Si Yu is softer and more delicate, and to avoid excessive liquid pressure caused by the partial blocking of the first liquid outlet hole 300, which could damage the liquid outlet part 2122.

[0136] By setting up the first liquid distribution channel 1000, the second liquid distribution channel 1100 and the third liquid distribution channel 1600, the liquid flow rate can be easily controlled.

[0137] Please combine them together Figures 1 to 22 The present disclosure now describes a liquid dispensing system according to another embodiment. The structure of the liquid dispensing system in this embodiment is similar to... Figure 32The embodiments shown are basically the same, except that the liquid outlet section 2122 of the liquid outlet system in this embodiment is further provided with an abutment surface 21221, and the number of liquid outlet holes is multiple, including multiple second liquid outlet holes 400, which do not include the first liquid outlet hole 300. The multiple second liquid outlet holes 400 are arranged around the abutment surface 21221, and the liquid outlet directions of the multiple second liquid outlet holes 400 intersect.

[0138] The movable component 30 is connected to the plurality of liquid outlets 2122 and abuts against the abutment surface 21221, driving the liquid outlets 2122 to protrude away from the movable component 30, so that the liquid outlet directions of the plurality of second liquid outlets 400 do not intersect. Separation of the movable component 30 from the plurality of liquid outlets 2122 allows the liquid outlets 2122 to reset. In this embodiment, the liquid outlets 2122 can be made of an elastomeric material.

[0139] The above-described liquid dispensing device is applied to a liquid dispensing system. Besides providing excellent cleaning performance, it also reduces the looseness and sparseness of the dispensing sections 2122, improving the dispensing effect. Specifically, the liquid dispensing device includes a rear cover mechanism 10 with an inlet channel 100, a face shell mechanism 20 mounted on the rear cover mechanism 10, and a movable component 30. The face shell mechanism 20 has a liquid dispensing chamber 200 and multiple dispensing sections 2122. The inlet channel 100 is connected to the outlet chamber 200. The outlet section 2122 is provided with an abutment surface 21221 and a plurality of second outlet holes 400. The second outlet holes 400 are connected to the outlet chamber 200. The plurality of second outlet holes 400 are arranged around the abutment surface 21221, and the outlet directions of the plurality of second outlet holes 400 intersect. This allows the liquid discharged from the plurality of second outlet holes 400 to converge into a liquid flow, forming a new liquid pattern and enhancing the impact of the liquid discharge. The movable component 30 is connected to the plurality of liquid outlet sections 2122 and abuts against the contact surface 21221. It drives the liquid outlet sections 2122 to protrude away from the movable component 30, preventing the liquid outlet directions of the plurality of second liquid outlet holes 400 from intersecting. This changes the convergence of the liquid outlet directions of the plurality of second liquid outlet holes 400 to parallel, or even further away from each other, preventing the liquid from converging during the filamentous rain process. It also expands the liquid outlet area of ​​the dispensing device, improving the filamentous rain dispensing effect. When the movable component 30 separates from the plurality of liquid outlet sections 2122, i.e., separates from the contact surface 21221, the liquid outlet sections 2122 can be reset, allowing the liquid discharged from the plurality of second liquid outlet holes 400 to re-converge into a single liquid stream. This allows the filamentous liquid outlet and the impact liquid outlet to have the same second outlet hole 400, thereby reducing the number of openings in the liquid outlet section 2122, increasing the strength of the liquid outlet section 2122, and preventing the liquid outlet section 2122 from being sparse and loose, thus improving the liquid outlet effect.

[0140] Furthermore, since different liquid dispensing modes have the same second liquid dispensing hole 400, the liquid dispensing position does not change before and after the liquid dispensing mode is switched. The switching of the liquid dispensing mode does not affect the liquid dispensing of the full shell mechanism 20 of the liquid dispensing device, and avoids the liquid dispensing positions of different liquid dispensing modes being dispersed in different liquid dispensing areas. As a result, the liquid dispensing device in this embodiment of the present disclosure has a large liquid dispensing area, ensuring that a better showering effect can be achieved before and after the liquid dispensing mode is switched.

[0141] In addition, the liquid outlet 2122 protrudes to the side away from the movable component 30, which can deform the wall of the second liquid outlet 400, thereby making the scale formed on the wall of the hole loose and easy to be flushed away by the liquid passing through the second liquid outlet 400, thus preventing the second liquid outlet 400 from being blocked by scale.

[0142] In the exemplary embodiments, please refer to Figure 34 , Figure 38 , Figure 40 , Figure 42 and Figure 31 The movable component 30 includes a body 31 and a plurality of abutting structures 32a. The plurality of abutting structures 32a are disposed on the body 31 and are disposed one-to-one with the plurality of abutting surfaces 21221. The body 31 is slidably connected to the shell mechanism 20. The abutting structure 32a can move closer to the body 31 and abut against the corresponding abutting surface 21221 and drive the corresponding liquid outlet 2122 to protrude to the side away from the movable component 30, or it can reset with the body 31 so that the liquid outlet 2122 is reset.

[0143] By driving the main body 31, multiple abutting structures 32a can be simultaneously abutted against the corresponding abutting surfaces 21221, driving the corresponding liquid outlet 2122 to protrude away from the moving component 30, so that the liquid outlet directions of multiple liquid outlet holes (second liquid outlet hole 400) do not intersect, forming a fine rain liquid outlet; or multiple abutting structures 32a can be simultaneously separated from the corresponding abutting surfaces 21221, so that the liquid outlet directions of multiple liquid outlet holes intersect again, forming an impact liquid outlet, ensuring the consistency of liquid outlet switching.

[0144] In the exemplary embodiments, please continue to refer to Figure 32The abutment structure 32a has a small end 32a1 facing the abutment surface 21221 and a large end 32a2 away from the abutment surface 21221 along its cross-section parallel to the direction of movement. With this configuration, the small end 32a1, being smaller in size, facilitates contact between the abutment structure 32a and the abutment surface 21221 without affecting the liquid entering the outlet hole (second outlet hole 400). Furthermore, the smaller end 32a1 allows the outlet portion 2122 to quickly reach the preset protrusion size, ensuring that the outlet directions of the multiple outlet holes do not intersect, achieving a fine, drizzling liquid discharge effect. By utilizing the larger size of the large end 32a2, the connection area between the abutting structure 32a and the body 31 can be increased, the strength of the abutting structure 32a can be increased, and the structural stability of the abutting structure 32a can be improved, ensuring that the abutting structure 32a can stably abut against the abutting surface 21221, thereby ensuring the stability of the protruding size and shape of the liquid outlet 2122 and ensuring the liquid discharge effect of the silk rain.

[0145] The side of the small end portion 32a1 facing the abutment surface 21221 has a blunt surface to avoid puncturing or scratching the abutment surface 21221 and to improve the lifespan of the liquid outlet portion 2122. It can be understood that in other embodiments, the side of the small end portion 32a1 facing the abutment surface 21221 may also be a plane or a slope, etc., so as to change the shape of the liquid outlet portion 2122 protruding away from the moving component 30.

[0146] In the exemplary embodiments, please refer to Figure 34 , Figure 38 , Figure 40 , Figure 42 and Figure 32 The main body 31 is provided with a guide member 311, which engages with the shell mechanism 20 to guide and restrict the movement direction of the movable component 30. The guide member 311 further increases the connection area between the main body 31 and the shell mechanism 20, improving connection stability. Furthermore, the guiding engagement between the guide member 311 and the shell mechanism 20 ensures the movement accuracy of the movable component 30, thereby ensuring the contact accuracy between the movable component 30 and the multiple contact surfaces 21221.

[0147] In an exemplary embodiment, such as Figure 38 , Figure 41 and Figure 42As shown, the rear cover mechanism 10 has a boss 11, and the front shell mechanism 20 is provided with a guide hole 600, through which a guide member 311 passes. The front shell mechanism 20 can rotate relative to the rear cover mechanism 10 to drive the guide member 311 to slide along the boss 11, so that the body 31 approaches the multiple liquid outlets 2122, thereby allowing the abutment structure 32a to move along with the body 31 to approach the corresponding abutment surface 21221 and drive the corresponding liquid outlet 2122 to protrude away from the movable component 30. In this way, the guide hole 600 allows the guide member 311 to contact the boss 11 through the guide hole 600, so that as the guide member 311 slides along the boss 11, it can change the distance between the movable component 30 and the multiple liquid outlets 2122 according to the degree of outward protrusion of the boss 11 towards the front shell mechanism 20, until the abutment structure 32a drives the corresponding liquid outlet 2122 to protrude away from the movable component 30. The extension direction of the boss 11 matches the rotation trajectory of the guide 311 to ensure that the guide 311 can always contact the boss 11 during the movement of the movable component 30 to the multiple liquid outlets 2122, thus ensuring the smooth movement of the movable component 30 to the multiple liquid outlets 2122.

[0148] It can be understood that in other embodiments, the active component 30 can be driven by other driving structures to move relative to the face shell mechanism 20, driving the liquid outlet 2122 to protrude to the side away from the active component 30, so that the liquid outlet directions of the multiple liquid outlet holes do not intersect, or separate from the abutment surface 21221, so that the liquid outlet 2122 is reset.

[0149] For example, such as Figure 43 and Figure 32 As shown, the movable component 30 can be driven by the pressing structure 33 to move relative to the faceplate mechanism 20. Correspondingly, the faceplate mechanism 20 can be fixedly connected to the rear cover mechanism 10. The faceplate mechanism 20 can also be rotatably connected to the rear cover mechanism 10, driving the movable component 30 to move relative to the faceplate mechanism 20, either separately or jointly with the pressing structure 33. In some embodiments, the movement of the movable component 30 relative to the faceplate mechanism 20 can also drive the faceplate mechanism 20 to move relative to the rear cover mechanism 10. In other embodiments, the movement of the movable component 30 relative to the faceplate mechanism 20 can also be hydraulically driven by the liquid entering the liquid outlet device. The movement of the movable component 30 relative to the faceplate mechanism 20 can also be driven by an electronic control mechanism disposed on the rear cover mechanism 10 or the faceplate mechanism 20.

[0150] In an exemplary embodiment, such as Figure 32As shown, the boss 11 is provided with an inclined surface 111, and the guide member 311 is provided with a guide surface 3111 that can guide and cooperate with the inclined surface 111. This guide surface 3111 ensures a smoother fit between the guide member 311 and the boss 11. During the rotation of the faceplate mechanism 20 relative to the rear cover mechanism 10, the guide surface 3111 can slide along the inclined surface 111, allowing the abutment structure 32a to move closer to the corresponding abutment surface 21221 along with the body 31 and drive the corresponding liquid outlet 2122 to protrude away from the movable component 30.

[0151] In the exemplary embodiments, please refer to Figure 36 , Figure 40 and Figure 35 One of the rear cover mechanism 10 and the front cover mechanism 20 is provided with a positioning component 40, and the other is provided with a positioning element. The positioning element is provided with a first positioning part 700 and a second positioning part 800. The first positioning part 700 and the second positioning part 800 are configured to cooperate with the positioning component 40 to perform positioning when the movable component 30 is connected to or separated from the multiple liquid outlets 2122.

[0152] In this embodiment of the present disclosure, the first positioning part 700 and the second positioning part 800 are configured to cooperate with the positioning component 40 to perform positioning when the liquid outlet part 2122 is in a protruding or reset state, respectively, so as to be able to sense whether the face shell mechanism 20 has moved to a preset position, thereby realizing the sensing that the liquid outlet part 2122 corresponding to each preset position is in a protruding or reset state.

[0153] The positioning assembly 40 includes a mounting component 41, an abutting component 42, and an elastic component 43. The mounting component 41 is disposed in either the rear cover mechanism 10 or the front cover mechanism 20, and has a mounting space. The abutting component 42 is partially located in the mounting space and can be slidably connected with the positioning component. The elastic component 43 is installed in the mounting space and can abut the abutting component 42 against the positioning component. The elastic component 43 ensures a tighter fit between the abutting component 42 and the positioning component, preventing gaps between them that could cause abnormal noise when the abutting component 42 slides against the positioning component.

[0154] In this embodiment, the first positioning part 700 and the second positioning part 800 are groove structures. The elastic member 43 can also make the abutting member 42 relatively stably positioned within the groove structure, improving the accuracy of position sensing. The elastic member 43 can be, but is not limited to, a metal spring or a plastic spring. In this embodiment, the mounting member 41 has a columnar structure and is disposed on the rear cover mechanism 10. The positioning member is disposed on the liquid distribution member 24.

[0155] In the exemplary embodiments, please refer to Figure 41 and Figure 35The faceplate mechanism 20 includes a shell assembly 21 and a reset member 22. The shell assembly 21 can enclose a liquid outlet cavity 200 and can rotate relative to the rear cover mechanism 10. Multiple liquid outlets 2122 are disposed on the shell assembly 21. The reset member 22 is disposed on the shell assembly 21 or the rear cover mechanism 10. The reset member 22 is configured to generate a driving force for the movable component 30 to reset, so that multiple abutment structures 32a can reset with the body 31. In this embodiment, the reset member 22 is a helical spring. During the rotation of the shell assembly 21 relative to the rear cover mechanism 10, the guide member 311 slides along the boss 11 and causes the movable component 30 to move closer to the multiple liquid outlets 2122. The body 31 can compress the reset member 22, generate a driving force for the movable component 30 to reset, and make the guide member 311 fit tightly with the boss 11, ensuring the fitting accuracy of the guide member 311 and the boss 11. As the guide member 311 slides along the boss 11, and the outward protrusion of the boss 11 toward the faceplate mechanism 20 gradually decreases, the reset member 22 can drive the movable component 30 away from the multiple liquid outlets 2122, thereby resetting the movable component 30. Furthermore, in some exemplary embodiments, the reset member 22 can also be a magnetic element, generating a magnetic force on the movable component 30 to drive it to reset.

[0156] In the exemplary embodiments, please continue to refer to Figure 41 and Figure 34 The reset element 22 is a helical spring, clamped between the movable component 30 and the housing component 21, and positioned and connected to at least one of the movable component 30 and the housing component 21 to ensure the stability of the reset element 22, thereby ensuring the directional accuracy of the reset driving force of the movable component 30. In this embodiment, the housing component 21 is provided with a connecting post 21211, and the movable component 30 is provided with a connecting groove 900 opposite to the connecting post 21211. One end of the reset element 22 is sleeved on the connecting post 21211, and the other end is received in the connecting groove 900. The body 31 can compress the reset element 22 when it is close to the multiple liquid outlets 2122 to generate the driving force for the reset of the movable component 30.

[0157] In the exemplary embodiments, please refer to Figure 38 , Figure 40 and Figure 33The faceplate mechanism 20 also includes a sealing component 23, which is disposed on the housing assembly 21 and sleeved on the guide member 311, providing a sliding seal with the guide member 311. This sealing component 23 ensures the sealing of the guide hole 600, preventing liquid from overflowing between the guide member 311 and the guide hole 600. Furthermore, the sealing component 23 increases the connection area between the guide member 311 and the housing assembly 21, improving the guiding stability between them. The sealing assembly 23 includes a cover 231 and a seal 232. The seal 232 is sleeved on the guide 311 and received in a receiving groove provided in the housing assembly 21. The seal 232 is located between the guide 311 and the housing assembly 21. The cover 231 is connected to the housing assembly 21 and sleeved on the guide 311. The cover 231 can seal the receiving groove to prevent the seal 232 from moving out of the receiving groove. The guide 311 passes through the seal 232 and extends out of the cover 231 to be able to contact the boss 11.

[0158] In the exemplary embodiments, please refer to Figure 35 , Figure 37 , Figure 38 , Figure 40 and Figure 29 The housing mechanism 20 also includes a liquid distribution component 24. The liquid distribution component 24 is disposed on the housing assembly 21 and forms a first liquid distribution channel 1000 and a second liquid distribution channel 1100 together with the housing assembly 21. The first liquid distribution channel 1000 and the second liquid distribution channel 1100 are respectively connected to the liquid outlet chamber 200. The liquid distribution component 24 is provided with a first channel hole 1001 communicating with the first liquid distribution channel 1000 and a second channel hole 1101 communicating with the second liquid distribution channel 1100. A first positioning part 700 and a second positioning part 800 are disposed on the liquid distribution component 24.

[0159] During the rotation of the faceplate mechanism 20 relative to the rear cover mechanism 10, the liquid inlet channel 100 can communicate with the first flow channel hole 1001 to reduce the liquid flow rate entering the liquid outlet chamber 200 from the liquid inlet channel 100. The faceplate mechanism 20 can also drive the movable component 30 to connect with multiple liquid outlet sections 2122, causing the liquid outlet sections 2122 to protrude away from the movable component 30. Alternatively, the liquid inlet channel 100 can communicate with the second flow channel hole 1101 to increase the liquid flow rate. The faceplate mechanism 20 can then drive the movable component 30 to separate from the multiple liquid outlet sections 2122, i.e., from the multiple contact surfaces 21221, so that the liquid outlet sections 2122 return to their original positions. Thus, during the "silk rain" dispensing process, reducing the liquid flow rate entering the liquid outlet chamber 200 from the liquid inlet channel 100 ensures a softer and more delicate dispensing experience. During the "impact dispensing" process, increasing the liquid flow rate ensures the impact force of the liquid discharged from the outlet hole, further guaranteeing the impact feel of the dispensing.

[0160] During the rotation of the faceplate mechanism 20 relative to the rear cover mechanism 10, the liquid inlet channel 100 can communicate with the first flow channel hole 1001 to reduce the liquid flow rate entering the liquid outlet chamber 200 from the liquid inlet channel 100, or communicate with the second flow channel hole 1101 to increase the liquid flow rate. Thus, by communicating the liquid inlet channel 100 with the first distribution channel 1000 and the second distribution channel 1100 respectively, the liquid flow rate can be easily controlled.

[0161] Please combine them together Figures 32 to 42 , Figure 33 The housing assembly 21 includes a faceplate 211, a liquid outlet component 212, and an inner frame 213. The faceplate 211 has multiple mounting holes. Multiple liquid outlet components 2122 are installed one-to-one with each mounting hole to ensure the stability of the position of the liquid outlet components 2122 relative to the faceplate 211. The liquid outlet component 212 is disposed on one side of the faceplate 211 and, together with the inner frame 213, forms a liquid outlet cavity 200. The inner frame 213 is connected to the faceplate 211 and fixes the liquid outlet component 212 to the faceplate 211. The liquid outlet component 212 includes a body portion 2121 and multiple liquid outlet components 2122 disposed on the body portion 2121. The liquid outlet component 2122 has a columnar structure, including a circumferential wall and a liquid outlet surface. The circumferential wall and the liquid outlet surface together form a liquid outlet groove 1200 communicating with the liquid outlet cavity 200. The liquid outlet hole communicates with the liquid outlet cavity 200 through the liquid outlet groove 1200. In this embodiment, the guide hole 600, the liquid distribution component 24, and the sealing assembly 23 are disposed on the inner frame 213. The connecting post 21211 is disposed on the body portion 2121. The face cover 211 is provided with a driving protrusion 2111 to facilitate the rotation of the face shell mechanism 20 relative to the rear cover mechanism 10.

[0162] In the exemplary embodiments, please refer to Figure 37 , Figure 41 and Figures 42 to 45 The rear cover mechanism 10 includes a rear cover assembly 12 and an elastic component 13. The elastic component 13 is disposed on the rear cover assembly 12. The elastic component 13 has a through hole 1300, which communicates with the liquid inlet channel 100. The elastic component 13 elastically abuts against the liquid distributor 24. During the rotation of the face shell mechanism 20 relative to the rear cover mechanism 10, the elastic component 13 can slide relative to the liquid distributor 24, so that the through hole 1300 communicates with the first flow channel hole 1001 to reduce the liquid flow rate, or so that the through hole 1300 communicates with the second flow channel hole 1101 to increase the liquid flow rate. In this way, during the rotation of the face shell mechanism 20 relative to the rear cover mechanism 10, the elastic component 13 can always abut against the liquid distributor 24, preventing liquid from being discharged between the elastic component 13 and the liquid distributor 24, so that the liquid has a certain flow direction under the restriction of the elastic component 13 and the liquid distributor 24, ensuring that the liquid can stably flow into the first flow channel hole 1001 or the second flow channel hole 1101.

[0163] The elastic component 13 includes a flexible element 131 and an elastic element 132. The flexible element 131 can elastically abut against the liquid distribution component 24. The flexible element 131 can better fit the liquid distribution component 24 through its own deformation, thereby improving the sealing performance between the elastic component 13 and the liquid distribution component 24. The rear cover assembly 12 includes a rear cover 121, an inlet pipe 122, and a connector 123. The inlet pipe 122 is disposed on the rear cover 121 and connected to the connector 123. The inlet channel 100 passes through the inlet pipe 122 and the connector 123 in sequence. The connector 123 is provided with a mounting groove 1400 communicating with the inlet channel 100. The elastic element 132 is installed in the mounting groove 1400 and supported between the connector 123 and the flexible element 131, so as to further enhance the elastic abutment force of the flexible element 131 against the liquid distribution component 24, thereby further improving the sealing stability between the elastic component 13 and the liquid distribution component 24. A through hole 1300 passes through the flexible member 131 and communicates with the liquid inlet channel 100 via the mounting groove 1400. The flexible member 131 may be made of, but is not limited to, rubber. The elastic member 132 may be, but is not limited to, a metal spring or a plastic spring.

[0164] In the exemplary embodiments, please refer to Figures 46 to 66 The faceplate mechanism 20 also includes a liquid distribution component 24. The liquid distribution component 24 is disposed on the housing assembly 21 and together with the housing assembly 21 forms a first liquid distribution channel 1000 and a second liquid distribution channel 1100. The first liquid distribution channel 1000 and the second liquid distribution channel 1100 are respectively connected to the liquid outlet chamber 200. The liquid distribution component 24 is provided with a first channel hole 1001 communicating with the first liquid distribution channel 1000 and a second channel hole 1101 communicating with the second liquid distribution channel 1100.

[0165] The liquid dispensing device also includes a switching component 50, disposed on the rear cover mechanism 10, configured to selectively introduce the liquid inlet channel 100 into one of the first flow channel hole 1001 and the second flow channel hole 1101, thereby changing the liquid flow rate entering the liquid outlet chamber 200 from the liquid inlet channel 100. For example, when the liquid outlet section 2122 protrudes to the side away from the movable component 30 and is in the drizzle dispensing state, the switching component 50 can connect the liquid inlet channel 100 with the first flow channel hole 1001 to reduce the liquid flow rate entering the liquid outlet chamber 200 from the liquid inlet channel 100; when the liquid outlet section 2122 is reset and is in the impact dispensing state, the switching component 50 can connect the liquid inlet channel 100 with the second flow channel hole 1101 to increase the liquid flow rate entering the liquid outlet chamber 200 from the liquid inlet channel 100. In this embodiment of the disclosure, the switching component 50 includes a drive member 51 and a switching member 52. The drive member 51 can drive the switching member 52 to rotate, thereby sealing one of the first flow channel hole 1001 and the second flow channel hole 1101, and connecting the other to the liquid inlet flow channel 100. The drive member 51 can be, but is not limited to, a push button, a roller, a button, or a handle.

[0166] Please combine them togetherFigures 1 to 22 The liquid dispensing system provided in another embodiment of this disclosure will now be described. The structure of the liquid dispensing system in this embodiment is similar to... Figure 46 The embodiments shown are essentially the same, except that the faceplate mechanism 20 of the liquid dispensing system in this embodiment is movably mounted on the rear cover mechanism 10. The liquid dispensing port includes a first liquid dispensing port 300, but does not include a plurality of second liquid dispensing ports 400.

[0167] The faceplate mechanism 20 is configured to move relative to the rear cover mechanism 10, reducing the liquid flow rate entering the outlet chamber 200 from the inlet channel 100 and driving the movable component 30 to connect with multiple outlet sections 2122, thereby reducing the flow area of ​​the multiple outlet holes (first outlet holes 300); or increasing the liquid flow rate and driving the movable component 30 to separate from and reset the multiple outlet sections 2122. In this embodiment, the multiple outlet holes include multiple first outlet holes 300.

[0168] The above-described liquid dispensing device is used in a liquid dispensing system. Besides providing excellent cleaning performance, it also avoids the problem of small diameter outlet holes (first outlet hole 300), reducing the likelihood of blockage and scaling. Furthermore, it meets the needs of some users who require a strong liquid dispensing impact. Specifically, the liquid dispensing device includes a rear cover mechanism 10 with an inlet channel 100, a movable component 30, and a faceplate mechanism 20 movably mounted on the rear cover mechanism 10. The faceplate mechanism 20 has an outlet chamber 200 and multiple outlet sections 2122. After entering the outlet chamber 200 through the inlet channel 100, the liquid exits through the outlet holes on the multiple outlet sections 2122. The faceplate mechanism 20 is configured to move relative to the rear cover mechanism 10, reducing the liquid flow rate entering the outlet chamber 200 from the inlet channel 100 and driving the movable component 30 to connect with multiple outlet sections 2122. This reduces the flow area of ​​the multiple outlet holes, forming a fine, wispy liquid flow. Simultaneously, reducing the liquid flow rate ensures a smooth and delicate wispy liquid flow, preventing excessive liquid pressure due to the reduced flow area of ​​the outlet holes, which could damage the outlet sections 2122. The faceplate mechanism 20 is also configured to move relative to the rear cover mechanism 10, increasing the liquid flow rate and driving the movable component 30 to reset. This increases both the liquid pressure and the flow area of ​​the outlet holes, facilitating the discharge of impurities and preventing clogging of the outlet holes. Furthermore, the greater impact force of the liquid helps to flush away existing scale and provides a satisfying impact during the liquid flow.

[0169] In the exemplary embodiments, please refer to Figure 47 , Figure 51 , Figure 55 , Figure 56 and Figure 46The active component 30 includes a body 31 and multiple shielding structures 32c. The shielding structures 32c are mounted on the body 31 and correspond one-to-one with multiple liquid outlets 2122. The body 31 is slidably connected to the faceplate mechanism 20. The shielding structures 32c can move closer to and connect with the corresponding liquid outlet 2122 as the body 31 moves, partially shielding the corresponding liquid outlet and reducing its flow area; or they can reset with the body 31. By driving the body 31, the multiple shielding structures 32c can synchronously connect with the corresponding liquid outlet 2122, reducing its flow area; or they can synchronously separate from the corresponding liquid outlet 2122, increasing its flow area. This allows the flow area of ​​each liquid outlet to change synchronously, ensuring consistent liquid flow. Furthermore, the shielding structure 32c only changes the flow area of ​​the corresponding liquid outlet to achieve liquid outlet mode switching (drizzle liquid outlet and impact liquid outlet), while the position of the liquid outlet does not change. This ensures that the switching of the liquid outlet mode does not affect the liquid outlet of the full shell mechanism 20 of the liquid outlet device, and avoids the liquid outlet sections 2122 of different liquid outlet modes being dispersed in different liquid outlet areas. As a result, the liquid outlet device in this embodiment has a larger liquid outlet area, ensuring that a better showering effect can be achieved before and after the liquid outlet mode is switched.

[0170] In the exemplary embodiments, please refer to Figure 47 , Figure 51 , Figures 55 to 60 , Figures 57 to 60 The shielding structure 32c can be at least partially inserted into the corresponding liquid outlet hole. This insertion action of the shielding structure 32c removes scale formed on the liquid outlet hole, further improving the descaling effect. The shielding structure 32c, being at least partially inserted into the corresponding liquid outlet hole, forms at least one flow area 1700 between the shielding structure 32c and the hole wall forming the corresponding liquid outlet hole, thus partially shielding the corresponding liquid outlet hole. The flow area 1700 is part of the liquid outlet hole (first liquid outlet hole 300). Compared to the liquid outlet hole, the flow area 1700 has a smaller flow area, enabling the formation of a fine, drizzling liquid flow.

[0171] In an exemplary embodiment, such as Figure 58 As shown, the circumferential outer wall of the shielding structure 32c is provided with at least one first protrusion 32c1 to change the number of flow areas 1700 and / or the cross-sectional shape and size perpendicular to the liquid flow direction. The first protrusion 32c1 can fit against the hole wall to further improve the descaling effect. Furthermore, the number and shape of the flow areas 1700 and / or the cross-sectional shape and size perpendicular to the liquid flow direction can be changed by altering the number of first protrusions 32c1, the shape of the first protrusions 32c1, and the space enclosed by adjacent first protrusions 32c1 and the hole wall.

[0172] In this embodiment, the number of first protrusions 32c1 is four, evenly distributed around the liquid flow direction, and they enclose four flow areas 1700 with the orifice wall, thereby changing the liquid outlet from a single-hole liquid outlet to a four-hole filamentary liquid outlet. The shielding structure 32c has an equal cross-section along the direction perpendicular to the liquid flow, and a first guide groove 32c10 extending into the liquid outlet can be formed between adjacent first protrusions 32c1 to guide the liquid flow and facilitate the smooth passage of the liquid through the flow area 1700. The cross-sectional shape of the liquid outlet along the direction perpendicular to the liquid flow can be circular (e.g., ...). Figure 62 (As shown), regular shapes such as ellipses, triangles, squares, trapezoids, parallelograms, or hexagons, as well as irregular shapes, such as... Figure 46 As shown, the liquid outlet includes a main body portion 301 and a branch portion 302 surrounding the main body portion 301. In this case, the shielding structure 32c can be inserted only into the main body portion 301, or it can be inserted into both the main body portion 301 and the branch portion 302, forming a flow area 1700 in the main body portion 301 and / or the branch portion 302.

[0173] In an exemplary embodiment, such as Figure 55 , Figure 56 and Figure 58 As shown, the shielding structure 32c includes an insertion part 32c2 and a connecting part 32c3. The insertion part 32c2 is connected to the main body 31 through the connecting part 32c3. The connecting part 32c3 is provided with at least one second protrusion 32c4. The insertion part 32c2 can be inserted into the corresponding liquid outlet hole, and the second protrusion 32c4 can abut against the corresponding liquid outlet part 2122. In this way, the insertion action of the insertion part 32c2 can remove the scale formed on the liquid outlet hole, further improving the descaling effect. The second protrusion 32c4 abuts against the corresponding liquid outlet part 2122, which can limit the size of the insertion part 32c2 protruding from the liquid outlet part 2122, reducing the risk of scratching or puncturing the user.

[0174] The insertion portion 32c2 is spaced apart from the corresponding orifice wall to form a flow area 1700. At least one second protrusion 32c4 can change the number and / or the cross-sectional shape and size perpendicular to the liquid flow direction of the connecting area between the liquid outlet chamber 200 and the corresponding flow area 1700. This allows the second protrusion 32c4 to shield the flow area 1700 on the upstream side. By changing the number and shape of the second protrusions 32c4 and the space enclosed by adjacent second protrusions 32c4, the number and / or the cross-sectional shape and size perpendicular to the liquid flow direction of the connecting area between the liquid outlet chamber 200 and the corresponding flow area 1700 can be changed.

[0175] In this embodiment, the number of second protrusions 32c4 is four, evenly distributed around the liquid flow direction, and they can enclose four second guide channels 32c40 communicating with the flow area 1700, thereby changing the liquid outlet from a single-hole outlet to a four-hole filamentary outlet. Furthermore, the second guide channels 32c40 can guide the liquid flow, facilitating its smooth passage through the flow area 1700. The cross-sectional shape of the outlet hole perpendicular to the liquid flow direction can be circular (e.g., ...). Figure 62 (As shown), regular shapes such as ellipses, triangles, squares, trapezoids, parallelograms, or hexagons, or irregular shapes, such as... Figures 61 to 64 As shown, the liquid outlet includes a main body portion 301 and a branch portion 302 surrounding the main body portion 301. At this time, the insertion part 32c2 can be inserted only into the main body portion 301, or it can be inserted into both the main body portion 301 and the branch portion 302 at the same time, forming a flow area 1700 in the main body portion 301 and / or the branch portion 302.

[0176] In an exemplary embodiment, such as Figure 58 As shown, the shielding structure 32c can abut against the corresponding liquid outlet 2122. The shielding structure 32c can shield the upstream side of the liquid outlet. By changing the outer wall contour of the shielding structure 32c, the contour of the shielded area upstream of the liquid outlet is altered, thereby changing the number of connected areas between the liquid outlet cavity 200 and the corresponding liquid outlet and / or the cross-sectional shape and size perpendicular to the liquid flow direction. The cross-sectional shape of the liquid outlet perpendicular to the liquid flow direction can be circular (e.g., ...). Figure 62 (As shown), regular shapes such as ellipses, triangles, squares, trapezoids, parallelograms, or hexagons, or irregular shapes, such as... Figure 49 As shown, the liquid outlet includes a main body 301 and a branch portion 302 surrounding the main body 301. In this case, the shielding structure 32c can completely shield the main body 301 and expose the entire or part of the branch portion 302, or it can partially shield the main body 301 and expose the entire or part of the branch portion 302.

[0177] In the exemplary embodiments, please refer to Figure 53 and Figure 49 The main body 31 is provided with a guide member 311, which engages with the shell mechanism 20 to guide and restrict the movement direction of the movable component 30. This guide member 311 further increases the connection area between the main body 31 and the shell mechanism 20, improving connection stability. Furthermore, the guiding engagement between the guide member 311 and the shell mechanism 20 ensures the movement accuracy of the movable component 30, thereby ensuring the connection accuracy between the movable component 30 and the multiple liquid outlets 2122, and ensuring that the shielding effect on the liquid outlet holes achieves the expected result.

[0178] In the exemplary embodiments, please refer to Figure 53 and Figure 1 The rear cover mechanism 10 has a boss 11, and the front cover mechanism 20 has a guide hole 600, through which a guide member 311 passes. The front cover mechanism 20 rotates relative to the rear cover mechanism 10. During its movement relative to the rear cover mechanism 10, the front cover mechanism 20 drives the guide member 311 to slide along the boss 11, allowing the movable component 30 to connect with multiple liquid outlets 2122, thereby reducing the flow area of ​​the multiple liquid outlets. The guide hole 600 allows the guide member 311 to contact the boss 11, and as the guide member 311 slides along the boss 11, the distance between the movable component 30 and the multiple liquid outlets 2122 changes according to the degree of outward protrusion of the boss 11 towards the front cover mechanism 20, until it connects with the multiple liquid outlets 2122. The extension direction of the boss 11 matches the rotation trajectory of the guide 311 to ensure that the guide 311 is always in contact with the boss 11 during the movement of the movable component 30 to the multiple liquid outlets 2122, thus ensuring the smooth movement of the movable component 30 to the multiple liquid outlets 2122.

[0179] The faceplate mechanism 20 moves relative to the rear cover mechanism 10 via rotation, saving space required for this movement and making the liquid dispensing device more compact. To facilitate the rotation of the faceplate mechanism 20, a drive protrusion 2111 is also provided on it, such as... Figure 47 As shown. It can be understood that in other embodiments, the movement of the face shell mechanism 20 relative to the rear cover mechanism 10 can also be linear. For example, the face shell mechanism 20 moves toward the rear cover mechanism 10 in the opposite direction of the liquid discharge direction. The movable component 30 moves toward the rear cover mechanism 10 together with the face shell mechanism 20. The guide 311 abuts against the boss 11 before the face shell mechanism 20. At this time, as the face shell mechanism 20 moves toward the rear cover mechanism 10, the movable component 30 will move in the opposite direction of the movement direction of the face shell mechanism 20 and connect with multiple liquid discharge parts 2122.

[0180] In an exemplary embodiment, such as Figure 49 As shown, the guide member 311 is provided with a guide surface 3111 that can guide and cooperate with the boss 11. In this way, the guide surface 3111 can ensure a smoother cooperation between the guide member 311 and the boss 11.

[0181] In the exemplary embodiments, please refer to Figure 50 , Figure 53 , Figure 54 and Figure 50The faceplate mechanism 20 includes a housing assembly 21 and a reset member 22. The housing assembly 21 can enclose a liquid outlet cavity 200 and can rotate relative to the rear cover mechanism 10. The liquid outlet hole is provided on the housing assembly 21. The reset member 22 is provided on the housing assembly 21 or the rear cover mechanism 10. The reset member 22 is configured to generate a driving force for the movable component 30 to reset. This facilitates the reset of the reset member 22. In this embodiment, the reset member 22 is a helical spring. During the rotation of the housing assembly 21 relative to the rear cover mechanism 10, the guide member 311 slides along the boss 11 and causes the movable component 30 to move closer to the multiple liquid outlets 2122. The reset member 22 is compressed, generating a driving force for the movable component 30 to reset, and making the guide member 311 fit tightly with the boss 11, ensuring the fitting accuracy of the guide member 311 and the boss 11. As the guide member 311 slides along the boss 11, and the outward protrusion of the boss 11 toward the faceplate mechanism 20 gradually decreases, the reset member 22 can drive the movable component 30 away from the multiple liquid outlets 2122, thereby resetting the movable component 30. Furthermore, in some exemplary embodiments, the reset member 22 can also be a magnetic element, generating a magnetic force on the movable component 30 to drive it to reset.

[0182] In the exemplary embodiments, please refer to Figure 54 and Figure 49 The reset element 22 is a helical spring, clamped between the movable component 30 and the housing component 21, and positioned and connected to at least one of the movable component 30 and the housing component 21 to ensure the stability of the reset element 22, thereby ensuring the directional accuracy of the reset driving force of the movable component 30. In this embodiment, the housing component 21 is provided with a connecting post 21211, and the movable component 30 is provided with a connecting groove 900 opposite to the connecting post 21211. One end of the reset element 22 is sleeved on the connecting post 21211, and the other end is received in the connecting groove 900. The movable component 30 can compress the reset element 22 when it is close to the multiple liquid outlets 2122 to generate the driving force for the movable component 30 to reset.

[0183] In the exemplary embodiments, please refer to Figure 53 and Figure 47The faceplate mechanism 20 also includes a sealing component 23, which is disposed on the housing assembly 21 and sleeved on the guide member 311, providing a sliding seal with the guide member 311. This sealing component 23 ensures the sealing of the guide hole 600, preventing liquid from overflowing between the guide member 311 and the guide hole 600. Furthermore, the sealing component 23 increases the connection area between the guide member 311 and the housing assembly 21, improving the guiding stability between them. The sealing assembly 23 includes a cover 231 and a seal 232. The seal 232 is sleeved on the guide 311 and received in a receiving groove provided on the housing assembly 21. The seal 232 is located between the guide 311 and the housing assembly 21. The cover 231 is connected to the housing assembly 21 and sleeved on the guide 311. The cover 231 can seal the receiving groove to prevent the seal 232 from moving out of the receiving groove. The guide 311 passes through the seal 232 and exits from the cover 231 so as to be able to contact the boss 11.

[0184] In the exemplary embodiments, please refer to Figure 48 , Figure 51 , Figure 52 , Figure 65 , Figure 66 and Figure 47 The faceplate mechanism 20 also includes a liquid distribution component 24. The liquid distribution component 24 is disposed on the housing assembly 21 and forms a first liquid distribution channel 1000 and a second liquid distribution channel 1100 with the housing assembly 21. The first liquid distribution channel 1000 and the second liquid distribution channel 1100 are respectively connected to the liquid outlet chamber 200 and can form a first flow channel hole 1001 and a second flow channel hole 1101 on the liquid distribution component 24. During the movement of the faceplate mechanism 20 relative to the rear cover mechanism 10, the liquid inlet channel 100 can connect with the first flow channel hole 1001 to reduce the liquid flow rate, or connect with the second flow channel hole 1101 to increase the liquid flow rate. Thus, by connecting the liquid inlet channel 100 with the first liquid distribution channel 1000 and the second liquid distribution channel 1100 respectively, the liquid flow rate can be easily controlled to meet the needs of different liquid flow rates.

[0185] Please combine them together Figure 48 , Figure 49 , Figure 50 , Figure 51 , Figure 52 , Figure 53 , Figure 54 , Figure 56 , Figure 60 , Figure 64 and Figure 48The housing assembly 21 includes a faceplate 211, a liquid outlet component 212, and an inner frame 213. The faceplate 211 has multiple mounting holes. Multiple liquid outlet components 2122 are installed one-to-one with the mounting holes to ensure the stability of the position of the liquid outlet components 2122 relative to the faceplate 211. The liquid outlet component 212 is disposed on one side of the faceplate 211 and, together with the inner frame 213, forms a liquid outlet cavity 200. The inner frame 213 is connected to the faceplate 211 and fixes the liquid outlet component 212 to the faceplate 211. The liquid outlet component 212 includes a body portion 2121 and multiple liquid outlet components 2122 disposed on the body portion 2121. The liquid outlet component 2122 has a columnar structure, including a circumferential wall and a liquid outlet surface. The circumferential wall and the liquid outlet surface together form a liquid outlet groove 1200 communicating with the liquid outlet cavity 200. The liquid outlet hole communicates with the liquid outlet cavity 200 through the liquid outlet groove 1200. In this embodiment, the guide hole 600, the liquid distribution component 24, and the sealing assembly 23 are disposed on the inner frame 213. The connecting post 21211 is disposed on the main body 2121.

[0186] In the exemplary embodiments, please refer to Figure 52 and Figure 47 The rear cover mechanism 10 includes a rear cover assembly 12 and an elastic component 13. The elastic component 13 is disposed on the rear cover assembly 12. The elastic component 13 is provided with a through hole 1300, which communicates with the liquid inlet channel 100. The elastic component 13 elastically abuts against the liquid distributor 24. During the movement of the face shell mechanism 20 relative to the rear cover mechanism 10, the elastic component 13 can slide relative to the liquid distributor 24. The through hole 1300 communicates with the first flow channel hole 1001 to reduce the liquid flow rate, or communicates with the second flow channel hole 1101 to increase the liquid flow rate. This ensures that during the movement of the face shell mechanism 20 relative to the rear cover mechanism 10, the elastic component 13 can always abut against the liquid distributor 24, preventing liquid from being discharged between the elastic component 13 and the liquid distributor 24. This allows the liquid to have a certain flow direction under the constraint of the elastic component 13 and the liquid distributor 24, ensuring that the liquid can stably flow into the first flow channel hole 1001 or the second flow channel hole 1101.

[0187] The elastic component 13 includes a flexible element 131 and an elastic element 132. The flexible element 131 can elastically abut against the liquid distribution component 24. The flexible element 131 can better fit the liquid distribution component 24 through its own deformation, thereby improving the sealing performance between the elastic component 13 and the liquid distribution component 24. The rear cover assembly 12 includes a rear cover 121, an inlet pipe 122, and a connector 123. The inlet pipe 122 is disposed on the rear cover 121 and connected to the connector 123. The inlet channel 100 passes through the inlet pipe 122 and the connector 123 in sequence. The connector 123 is provided with a mounting groove 1400 communicating with the inlet channel 100. The elastic element 132 is installed in the mounting groove 1400 and supported between the connector 123 and the flexible element 131, so as to further enhance the elastic abutment force of the flexible element 131 on the liquid distribution component 24, thereby further improving the sealing stability between the elastic component 13 and the liquid distribution component 24. A through-hole 1300 passes through the flexible member 131 and communicates with the liquid inlet channel 100 via the mounting groove 1400. The flexible member 131 may be made of, but is not limited to, rubber. The elastic member 132 may be, but is not limited to, a metal spring or a plastic spring.

[0188] In an exemplary embodiment, such as ​ As shown, one of the rear cover mechanism 10 and the front shell mechanism 20 is provided with a positioning component 40, and the other is provided with a positioning element. The positioning element is provided with a first positioning part 700 and a second positioning part 800. The first positioning part 700 and the second positioning part 800 are configured to cooperate with the positioning component 40 to perform positioning when the movable component 30 is connected or separated from the multiple liquid outlets 2122, so as to sense whether the front shell mechanism 20 has moved to a preset position, thereby realizing the sensing of the connection or separation state of the movable component 30 and the multiple liquid outlets 2122 corresponding to each preset position.

[0189] The positioning assembly 40 includes a mounting component 41, an abutting component 42, and an elastic component 43. The mounting component 41 is disposed on one of the rear cover mechanism 10 and the front cover mechanism 20, and the mounting component 41 has an mounting space. The abutting component 42 is partially located in the mounting space and can be slidably connected with the positioning component. The elastic component 43 is installed in the mounting space and can abut the abutting component 42 against the positioning component. The elastic component 43 ensures a tighter fit between the abutting component 42 and the positioning component, preventing gaps between them that could cause abnormal noise when the abutting component 42 slides against the positioning component.

[0190] In this embodiment, the first positioning part 700 and the second positioning part 800 are groove structures. The elastic member 43 can also make the abutting member 42 relatively stably positioned within the groove structure, improving the accuracy of position sensing. The elastic member 43 can be, but is not limited to, a metal spring or a plastic spring. In this embodiment, the mounting member 41 has a columnar structure and is disposed on the rear cover mechanism 10. The positioning member is disposed on the liquid distribution member 24.
