[0087] The existing liquid outlet device generally adopts a liquid outlet hole to be arranged on the water outlet part to achieve different liquid outlet effects.

The liquid outlet device can be, but is not limited to, a faucet, a shower head, or a spray gun. To facilitate the description of the technical solution of the present disclosure, the following description takes the liquid outlet device as an example of a shower head.

[0089] The present disclosure provides a liquid outlet system, which includes a liquid outlet device.

[0092] The movable component is movably mounted on the liquid outlet cavity. The movable component is configured to be able to move relative to the main structure and to be connected to or separated from the plurality of liquid outlets.

[0093] In an exemplary embodiment, the main structure includes a rear cover mechanism and a face shell mechanism. The rear cover mechanism is provided with a liquid inlet channel.

[0094] The movable component can be movably installed in the liquid outlet cavity. The movable component is configured to be able to move relative to the surface shell mechanism and be connected to or separated from the multiple liquid outlet parts.

[0095] The liquid outlet device of the above scheme is applied to the liquid outlet system. In addition to making the liquid outlet system have excellent cleaning performance, it can also reduce the probability of blockage and scaling of the liquid outlet hole. Specifically, the liquid outlet device includes a rear cover mechanism provided with a liquid inlet channel, a surface shell mechanism installed on the rear cover mechanism, and a movable component. The surface shell mechanism is provided with a liquid outlet cavity and a plurality of liquid outlet parts. The liquid inlet channel is connected to the liquid outlet cavity, and the liquid outlet part is provided with a liquid outlet hole, and the liquid outlet hole is connected to the liquid outlet cavity. The movable component is configured to be able to move relative to the surface shell mechanism, connect or separate with the plurality of liquid outlet parts, so that the liquid outlet part can vibrate or elastically deform during the process of connecting and separating with the movable component, thereby making the scaling formed on the wall of the liquid outlet hole loose, so that it is easy to be washed away by the liquid passing through the liquid outlet hole, and avoid the liquid outlet hole being blocked by scaling.

[0096] The liquid outlet system of the present disclosure is described below by way of some exemplary embodiments.

[0097] Please combine Figures 1 to 3 , Figure 6 , Fig.10 , Fig.11 , Fig.13 , Fig.16 and Fig. 20, the liquid outlet system provided by an embodiment of the present disclosure is now described. The liquid outlet system includes a liquid outlet device. Among them, the liquid outlet device includes a rear cover mechanism 10, a surface shell mechanism 20 and a movable component 30. The rear cover mechanism 10 is provided with a liquid inlet channel 100. The surface shell mechanism 20 is installed on the rear cover mechanism 10. The surface shell mechanism 20 is provided with a liquid outlet cavity 200 and a plurality of liquid outlet portions 2122. The liquid inlet channel 100 is connected to the liquid outlet cavity 200. The liquid outlet portion 2122 is provided with liquid outlet holes, including a first liquid outlet hole 300 and a plurality of second liquid outlet holes 400. The first liquid outlet hole 300 and the plurality of second liquid outlet holes 400 are both connected to the liquid outlet cavity 200. The second liquid outlet holes 400 are arranged around the first liquid outlet hole 300. The movable component 30 can be movably installed in the liquid outlet cavity 200. The movable component 30 can be connected to the multiple liquid outlet parts 2122 to block the first liquid outlet hole 300, and the movable component 30 can be separated from the multiple liquid outlet parts 2122 to open the first liquid outlet hole 300.

[0098] The liquid outlet system also includes a liquid inlet assembly. The rear cover mechanism 10 is provided with a connection structure 1221 connected to the liquid inlet assembly. The connection structure 1221 can be connected to the liquid inlet assembly by, but not limited to, threaded connection, plug connection, clamping connection or welding. The liquid inlet assembly is configured to provide liquid to the liquid outlet device. The liquid inlet assembly can be, but not limited to, a manually controlled or electrically controlled valve structure, and the liquid outlet device is connected or disconnected with the liquid source by opening or closing the liquid inlet assembly. The liquid includes, but is not limited to, clean water or pure water from a municipal water network.

[0099] The liquid outlet device of the above scheme is applied to the liquid outlet system. In addition to making the liquid outlet system have excellent cleaning performance, it can also reduce the probability of clogging and scaling of the liquid outlet hole, and can meet the needs of some users for the impact of liquid outlet. Specifically, the liquid outlet device includes a rear cover mechanism 10 provided with a liquid inlet channel 100, a surface shell mechanism 20 installed on the rear cover mechanism 10, and a movable component 30. The surface shell mechanism 20 is provided with a liquid outlet cavity 200 and a plurality of liquid outlet parts 2122. The liquid inlet channel 100 is connected to the liquid outlet cavity 200, and the liquid outlet part 2122 is provided with a first liquid outlet hole 300 and a plurality of second liquid outlet holes 400. The first liquid outlet hole 300 and the plurality of second liquid outlet holes 400 are both connected to the liquid outlet cavity 200, and the second liquid outlet hole 400 is arranged around the first liquid outlet hole 300. The movable component 30 is configured to be able to move relative to the shell mechanism 20, and is connected to the plurality of liquid outlets 2122 to block the first liquid outlet 300, so that liquid is discharged only from the second liquid outlet 400, forming a silky liquid discharge, making the liquid discharge soft and delicate. The movable component 30 is configured to be able to move relative to the shell mechanism 20, and is separated from the plurality of liquid outlets 2122 to open the first liquid outlet 300, so that the first liquid outlet 300 and the second liquid outlet 400 discharge liquid at the same time, increasing the flow area of ​​the liquid outlet 2122, facilitating the discharge of impurities in the liquid, and not easily clogging the first liquid outlet 300 and the second liquid outlet 400, and the increase in the amount of liquid discharge can also enhance the impact of the liquid discharge. The movable component 30 is configured to be able to move relative to the surface shell mechanism 20, and to be connected or separated from the multiple liquid outlets 2122, so that the liquid outlets 2122 can generate vibration or elastic deformation during the process of connecting and separating with the movable component 30, thereby making the scale formed on the wall of the liquid outlet hole (the first liquid outlet hole 300 and the second liquid outlet hole 400) loose, so as to be easily flushed away by the liquid passing through the liquid outlet hole (the first liquid outlet hole 300 and the second liquid outlet hole 400), thereby avoiding the liquid outlet hole (the first liquid outlet hole 300 and the second liquid outlet hole 400) being blocked by scale.

[0100] In the exemplary embodiment, please combine Figures 2 to 5b , the radial dimension of the first liquid outlet hole 300 is greater than the radial dimension of the second liquid outlet hole 400, so that the liquid discharged from the second liquid outlet hole 400 is softer and more delicate when the silky rain is discharged. The liquid flow rate discharged from the first liquid outlet hole 300 is larger, and the impact of the liquid discharge is stronger. In addition, the second liquid outlet hole 400 with a smaller radial dimension is easily blocked by impurities. When the second liquid outlet hole 400 is blocked, the first liquid outlet hole 300 can still discharge liquid. At this time, the impurities blocking the second liquid outlet hole 400 will be carried out by the liquid and discharged from the first liquid outlet hole 300, which is conducive to removing impurities and restoring the original liquid discharge pattern of the first liquid outlet hole 300 and the plurality of second liquid outlet holes 400 as a whole.

[0101] The first liquid outlet hole 300 and the plurality of second liquid outlet holes 400 can discharge liquid at the same time, thereby increasing the liquid discharge area of ​​the liquid outlet portion 2122. When the liquid inlet assembly stops providing liquid to the liquid outlet device, the first liquid outlet hole 300 and the plurality of second liquid outlet holes 400 can discharge the residual liquid at the same time, thereby facilitating the accelerated discharge and draining of the residual liquid and slowing down the formation of scaling.

[0102] In an exemplary embodiment, if Figure 5b As shown, in the process of the movable component 30 blocking the first liquid outlet 300, the liquid outlet portion 2122 can be driven to bulge toward the side away from the movable component 30. In this way, each second liquid outlet 400 can change the liquid outlet direction as the liquid outlet portion 2122 bulges toward the side away from the movable component 30, so that the liquid outlets of each second liquid outlet 400 are spaced relatively far apart to avoid converging into one stream, thereby ensuring the soft and delicate characteristics of the rain-like liquid outlet. In the disclosed embodiment, the liquid outlet portion 2122 can be made of an elastomeric material. In addition, 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 drive the multiple liquid outlet portions 2122 to bulge or concave deformation until the driving force on the movable component 30 is greater than the friction force, so as to separate from the multiple liquid outlet portions 2122. During the above-mentioned convex and concave deformation process, the scale formed on the hole wall of the liquid outlet hole (the first liquid outlet hole 300 and the second liquid outlet hole 400) can be further loosened, so as to be easily flushed away by the liquid passing through the liquid outlet hole (the first liquid outlet hole 300 and the second liquid outlet hole 400), thereby preventing the liquid outlet hole (the first liquid outlet hole 300 and the second liquid outlet hole 400) from being blocked by the scale.

[0103] like Figure 5a As shown, the liquid discharge direction of the first liquid outlet 300 intersects with the liquid discharge direction of the second liquid outlet 400, and the angle α between the liquid discharge direction of the first liquid outlet 300 and the liquid discharge direction of the second liquid outlet 400 is less than or equal to 10°, so that the liquid discharged from the first liquid outlet 300 and the liquid discharged from the second liquid outlet 400 can converge into a liquid flow, forming a new liquid discharge pattern, further enhancing the impact of the liquid discharge. In the embodiment of the present disclosure, the liquid outflow direction of each second liquid outlet hole 400 converges toward the liquid outflow direction of the first liquid outlet hole 300 located at the center of each second liquid outlet hole 400 to form a stream of liquid outflow. In the process of the movable component 30 blocking the first liquid outlet hole 300, the liquid outlet portion 2122 can protrude toward the side away from the movable component 30, thereby changing the liquid outflow direction of each second liquid outlet hole 400 from converging toward the liquid outflow direction of the first liquid outlet hole 300 to being parallel, or even further deflecting toward the liquid outflow direction away from the first liquid outlet hole 300, thereby avoiding the convergence of the liquid outflows of each second liquid outlet hole 400 when the liquid is discharged in a drizzle, thereby ensuring the drizzle liquid discharge effect.

[0104] In the exemplary embodiment, please combine Figure 3and Figure 4 , the axis of the first liquid outlet hole 300 is parallel to the axis of the second liquid outlet hole 400, and the distance between the axis of the first liquid outlet hole 300 and the axis of the second liquid outlet hole 400 is less than or equal to 1mm. The movable component 30 moves relative to the shell mechanism 20 to open the first liquid outlet hole 300, and the first liquid outlet hole 300 and the second liquid outlet hole 400 can discharge liquid at the same time. The distance between the axis of the first liquid outlet hole 300 and the axis of the second liquid outlet hole 400 is less than or equal to 1mm, so that the distance between the liquid discharged from the first liquid outlet hole 300 and the liquid discharged from the second liquid outlet hole 400 is relatively close, which can form a Bernoulli effect, and the tension generated can make the liquid discharged from the first liquid outlet hole 300 and the liquid discharged from the second liquid outlet hole 400 adsorb into a liquid flow, forming a new liquid discharge pattern, so that the liquid discharge shape of the liquid discharge device is more uniform and regular, and the uniformity of the liquid discharge direction is ensured.

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

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

[0107] In the exemplary embodiment, please combine Figure 7 , Fig.11 and Fig.17The movable component 30 includes a body 31 and a plurality of blocking structures 32. The plurality of blocking structures 32 are arranged on the body 31 and correspond to the plurality of liquid outlets 2122. The body 31 is slidably connected to the surface shell mechanism 20. The blocking structure 32 can approach the corresponding liquid outlet 2122 with the body 31 and connect with the corresponding liquid outlet 2122 to block the corresponding first liquid outlet 300; or open the first liquid outlet 300 with the body 31 reset. In this way, by driving the body 31, the plurality of blocking structures 32 can synchronously block the corresponding first liquid outlet 300, and only the second liquid outlet 400 can discharge liquid; or the plurality of blocking structures 32 can synchronously open the corresponding first liquid outlet 300, so that the first liquid outlet 300 and the second liquid outlet 400 can discharge liquid at the same time, thereby ensuring the consistency of the liquid discharge switching. Moreover, the blocking structure 32 only changes the connection state between the corresponding first liquid outlet hole 300 and the liquid outlet cavity 200 to achieve the switching of the liquid outlet mode (silk rain liquid outlet and impact liquid outlet), while the liquid outlet position (the area where each first liquid outlet hole 300 and the corresponding second liquid outlet hole 400 are located) does not change, so 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 positions of different liquid outlet modes being dispersed in different liquid outlet areas, so that the liquid outlet device in the embodiment of the present disclosure has a larger liquid outlet area, ensuring that a better shower effect can be achieved before and after the liquid outlet mode is switched.

[0108] In the exemplary embodiment, please combine Figure 2 , Figure 7 and Fig.18 , the blocking structure 32 can be at least partially inserted into the corresponding first liquid outlet hole 300 to block the corresponding first liquid outlet hole 300. In this way, the plugging action of the blocking structure 32 can remove the scale formed in the first liquid outlet hole 300, further improving the descaling effect. The blocking structure 32 can be at least partially inserted into the corresponding first liquid outlet hole 300, so that the friction between the blocking structure 32 and the corresponding liquid outlet portion 2122 can drive the corresponding liquid outlet portion 2122 to convex or concave deformation.

[0109] In an exemplary embodiment, please continue to refer to Figure 2 , Figure 7 and Fig.18The plugging structure 32 includes an inserting portion 321 and a connecting portion 322. The inserting portion 321 is connected to the body 31 through the connecting portion 322. A plurality of protrusions 3221 are arranged on the circumferential outer side of the connecting portion 322. A guide groove 500 is arranged between two adjacent protrusions 3221. The inserting portion 321 can be inserted into the corresponding first liquid outlet hole 300 and the plurality of protrusions 3221 can abut against the corresponding liquid outlet portion 2122, so that the plurality of guide grooves 500 can be connected with the corresponding plurality of second liquid outlet holes 400 in a one-to-one correspondence. In this way, the scale formed in the first liquid outlet hole 300 can be removed by the inserting action of the inserting portion 321, further improving the descaling effect. The inserting portion 321 can cooperate with the hole wall gap forming the first liquid outlet hole 300. The insertion portion 321 may also be interference fit with the hole wall forming the first liquid outlet hole 300. In this case, the liquid outlet portion 2122 may be made of an elastomeric material so that the insertion portion 321 can be elastically deformed during the insertion of the insertion portion 321 in the first liquid outlet hole 300, so as to facilitate the insertion portion 321 to pass through the first liquid outlet hole 300. The above-mentioned interference fit can further enhance the effect of removing scale formed in the first liquid outlet hole 300. By utilizing the above-mentioned interference fit and / or the driving effect of the connection portion 322 on the liquid outlet portion 2122, the liquid outlet portion 2122 can protrude to the side away from the movable component 30, and the liquid outlet direction of the second liquid outlet hole 400 can be changed. The provision of the guide groove 500 can guide the liquid to the second liquid outlet hole 400 more smoothly, and prevent the connection portion 322 from interfering with the liquid entering the second liquid outlet hole 400. The side of the protrusion 3221 abutting against the corresponding liquid outlet 2122 can be a plane, an inclined surface or an arc surface, so as to change the shape of the liquid outlet 2122 protruding toward the side away from the movable component 30. By utilizing the above-mentioned interference fit, the friction between the insertion portion 321 and the corresponding liquid outlet 2122 can drive the corresponding liquid outlet 2122 to convex or concave deformation.

[0110] In the exemplary embodiment, please combine Figure 7 , Fig.11 , Fig.14 and Fig.21 The body 31 is provided with a guide member 311, and the guide member 311 cooperates with the surface shell mechanism 20 to limit the movement direction of the movable component 30. In this way, the setting of the guide member 311 can further increase the connection area between the body 31 and the surface shell mechanism 20, and improve the connection stability. In addition, the guiding cooperation between the guide member 311 and the surface shell mechanism 20 can ensure the movement accuracy of the movable component 30, and further ensure the blocking accuracy between the movable component 30 and the plurality of first liquid outlets 300.

[0111] In an exemplary embodiment, if Fig.11 and Fig.21As shown, the rear cover mechanism 10 has a boss 11, the face shell mechanism 20 is provided with a guide hole 600, and the guide member 311 is passed through the guide hole 600. The face 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 is close to the plurality of liquid outlets 2122.

[0112] In the disclosed embodiment, the face 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, and the blocking structure 32 can approach the corresponding liquid outlet 2122 with the body 31 and block the corresponding first liquid outlet 300. In this way, the guide hole 600 is provided to allow the guide member 311 to contact the boss 11 through the guide hole 600, so that the guide member 311 can change the distance between the movable component 30 and the plurality of liquid outlets 2122 according to the degree of protrusion of the boss 11 toward one side of the face shell mechanism 20 during the sliding process along the boss 11, until the blocking structure 32 blocks the corresponding first liquid outlet 300, or until the blocking structure 32 blocks the corresponding first liquid outlet 300 and causes the liquid outlet 2122 to protrude toward the side away from the movable component 30. The extension direction of the boss 11 matches the rotation trajectory of the guide member 311 to ensure that the guide member 311 can always contact the boss 11 during the movement of the movable component 30 toward the multiple liquid outlets 2122, thereby ensuring the smooth movement of the movable component 30 toward the multiple liquid outlets 2122.

[0113] It can be understood that in other embodiments, the movable component 30 can be driven by other driving structures to move relative to the face shell mechanism 20, to block the first liquid outlet 300 or to open the first liquid outlet 300. For example, the movable component 30 can be driven by a pressing structure to move relative to the face shell mechanism 20. Correspondingly, the face shell mechanism 20 can be fixedly connected to the back cover mechanism 10. The face shell mechanism 20 can also be rotatably connected to the back cover mechanism 10, and the pressing structure can drive the movable component 30 to move relative to the face shell mechanism 20 separately or together. In some embodiments, the movement of the movable component 30 relative to the face shell mechanism 20 can also drive the face shell mechanism 20 to move relative to the back cover mechanism 10. In other embodiments, the movement of the movable component 30 relative to the face shell mechanism 20 can also be driven by the hydraulic pressure of the liquid entering the liquid outlet device. The movement of the movable component 30 relative to the face shell mechanism 20 can also be driven by an electric control mechanism arranged in the back cover mechanism 10 or the face shell mechanism 20.

[0114] In an exemplary embodiment, if Figure 7 and Fig.11 As shown, the guide member 311 is provided with a guide surface 3111 that can cooperate with the boss 11. Thus, by providing the guide surface 3111, it is possible to ensure smoother cooperation between the guide member 311 and the boss 11.

[0115] In the exemplary embodiment, please combine Fig. 9 , Fig.11 and Fig.17 One of the rear cover mechanism 10 and the face shell mechanism 20 is provided with a positioning assembly 40, and the other is provided with a positioning member, the positioning member is provided with a first positioning portion 700 and a second positioning portion 800, and the first positioning portion 700 and the second positioning portion 800 are configured to cooperate with the positioning assembly 40 for positioning when the movable assembly 30 is connected to or separated from the multiple liquid outlets 2122, respectively.

[0116] In the embodiment of the present disclosure, the first positioning portion 700 and the second positioning portion 800 are configured to cooperate with the positioning assembly 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 surface shell mechanism 20 moves to the preset position, thereby realizing the sensing of whether the first liquid outlet 300 corresponding to each preset position is in a blocked state or an 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 on one of the rear cover mechanism 10 and the face shell mechanism 20. The mounting component 41 is provided with a mounting space. The abutting component 42 is partially located in the mounting space and can be slidably connected with the positioning member. The elastic component 43 is installed in the mounting space and can abut the abutting component 42 against the positioning member. In this way, the elastic component 43 can be disposed to make the abutting component 42 and the positioning member fit more closely, avoiding a gap between the abutting component 42 and the positioning member, which causes an abnormal sound when the abutting component 42 slides against the positioning member.

[0118] In the embodiment of the present disclosure, the first positioning portion 700 and the second positioning portion 800 are groove structures, and the elastic component 43 can also make the abutting component 42 relatively stably in the groove structure, thereby improving the accuracy of position sensing. The elastic component 43 can be, but is not limited to, a metal spring component or a plastic spring. In the embodiment of the present disclosure, the mounting component 41 is a columnar structure and is disposed on the rear cover mechanism 10. The positioning component is disposed on the liquid separation component 24.

[0119] In the exemplary embodiment, please combine Figure 8 , Fig.15 and Fig. 22The face shell 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. A plurality of liquid outlets 2122 are provided on the shell assembly 21. The reset member 22 is provided on the shell assembly 21 or the rear cover mechanism 10. The reset member 22 is configured to generate a driving force for resetting the movable assembly 30, so that the plurality of blocking structures 32 can be reset along with the body 31. In the disclosed embodiment, the reset member 22 is a coil 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 makes the movable assembly 30 approach the plurality of liquid outlets 2122. The body 31 can compress the reset member 22, generate a driving force for resetting the movable assembly 30, and make the guide member 311 fit tightly with the boss 11, thereby ensuring the matching accuracy between the guide member 311 and the boss 11. When the guide member 311 slides along the boss 11 and the protrusion of the boss 11 toward the side of the housing mechanism 20 gradually decreases, the reset member 22 can drive the movable assembly 30 away from the plurality of liquid outlets 2122 to reset the movable assembly 30. In addition, in some exemplary embodiments, the reset member 22 can also be a magnetic member, which generates a magnetic attraction force on the movable assembly 30 to drive the movable assembly 30 to reset.

[0120] In an exemplary embodiment, please continue to refer to Figure 8 , Fig.15 and Fig. 22 The reset member 22 is a coil spring, which is clamped between the movable assembly 30 and the housing assembly 21 and is positioned and connected to at least one of the movable assembly 30 and the housing assembly 21 to ensure the stability of the position of the reset member 22, thereby ensuring the directional accuracy of the reset driving force of the movable assembly 30. In the disclosed embodiment, the housing assembly 21 is provided with a connecting column 21211, and the movable assembly 30 is provided with a connecting groove 900 arranged opposite to the connecting column 21211. One end of the reset member 22 is sleeved on the connecting column 21211, and the other end is accommodated in the connecting groove 900. The body 31 is close to the multiple liquid outlets 2122 to compress the reset member 22 to generate a driving force for resetting the movable assembly 30.

[0121] In the exemplary embodiment, please combine Figure 6 , Fig.14 and Fig.21The face shell mechanism 20 further includes a sealing assembly 23, which is disposed on the housing assembly 21 and sleeved on the guide member 311, and is slidably sealed with the guide member 311. Thus, the sealing assembly 23 can ensure the sealing of the guide hole 600, and prevent the liquid from overflowing from between the guide member 311 and the guide hole 600. In addition, the sealing assembly 23 can also increase the connection area between the guide member 311 and the housing assembly 21, and improve the guiding stability between the guide member 311 and the housing assembly 21. The sealing assembly 23 includes a cover body 231 and a sealing member 232. The sealing member 232 is sleeved on the guide member 311 and accommodated in a receiving groove arranged on the shell assembly 21, and the sealing member 232 is arranged between the guide member 311 and the shell assembly 21. The cover body 231 is connected to the shell assembly 21 and sleeved on the guide member 311. The cover body 231 can cover the receiving groove to prevent the sealing member 232 from moving out of the receiving groove. The guide member 311 passes through the sealing member 232 and extends from the cover body 231 so as to be able to contact the boss 11.

[0122] In the exemplary embodiment, please combine Figure 6 , Fig.11 , Fig.12 , Fig.14 , Fig.17 , Fig.19 and Fig.21 The shell mechanism 20 further includes a liquid separator 24. The liquid separator 24 is disposed on the housing assembly 21 and encloses the housing assembly 21 to form a first liquid separator channel 1000 and a second liquid separator channel 1100. The first liquid separator channel 1000 and the second liquid separator channel 1100 are respectively connected to the liquid outlet cavity 200. The liquid separator 24 is provided with a first channel hole 1001 connected to the first liquid separator channel 1000 and a second channel hole 1101 connected to the second liquid separator channel 1100.

[0123] During the rotation of the face shell mechanism 20 relative to the rear cover mechanism 10, the liquid inlet channel 100 can be connected with the first channel hole 1001 to reduce the liquid flow rate from the liquid inlet channel 100 into the liquid outlet cavity 200, and the face shell mechanism 20 can drive the movable component 30 to connect with the multiple liquid outlets 2122 to block the first liquid outlet 300; or the liquid inlet channel 100 can be connected with the second channel hole 1101 to increase the liquid flow rate, and the face shell mechanism 20 can drive the movable component 30 to separate from the multiple liquid outlets 2122 to open the first liquid outlet 300. In this way, when the first liquid outlet 300 is in a blocked state, by reducing the liquid flow rate from the liquid inlet channel 100 into the liquid outlet cavity 200, it can ensure that the silky liquid outflow is softer and more delicate, and it can avoid excessive liquid pressure after the first liquid outlet 300 is blocked, causing the liquid outlet 2122 to be damaged by the liquid pressure. When the first liquid outlet 300 is in an open state, the liquid pressure can be ensured by increasing the liquid flow rate, thereby ensuring the impact force of the liquid discharged from the first liquid outlet 300 and the liquid discharged from the second liquid outlet 400, and ensuring the impact feeling of the liquid discharge.

[0124] During the rotation of the face shell mechanism 20 relative to the rear cover mechanism 10, the liquid inlet channel 100 can be connected to the first channel hole 1001 to reduce the liquid flow rate from the liquid inlet channel 100 into the liquid outlet cavity 200, or connected to the second channel hole 1101 to increase the liquid flow rate. In this way, the liquid inlet channel 100 is connected to the first liquid distribution channel 1000 and the second liquid distribution channel 1100 respectively, so as to facilitate the control of the liquid flow rate.

[0125] Please combine Figure 2 , Figures 6 to 8 , Fig.11 , Fig.12 , Fig.14 , Fig.15 , Fig.17 , Fig.21 and Fig. 22The housing assembly 21 includes a face cover 211, a liquid outlet component 212 and an inner frame 213. The face cover 211 is provided with a plurality of mounting holes. A plurality of liquid outlets 2122 are mounted one by one with the plurality of mounting holes to ensure the stability of the position of the liquid outlet 2122 relative to the face cover 211. The liquid outlet component 212 is arranged on one side of the face cover 211 and is surrounded by the inner frame 213 to form a liquid outlet cavity 200. The inner frame 213 is connected to the face cover 211 and fixes the liquid outlet component 212 to the face cover 211. The liquid outlet component 212 includes a body portion 2121 and a plurality of liquid outlets 2122 arranged on the body portion 2121. The liquid outlet portion 2122 is a columnar structure, including a circumferential wall and a liquid outlet surface. The circumferential wall and the liquid outlet surface are surrounded by a liquid outlet groove 1200 connected to the liquid outlet cavity 200. The first liquid outlet 300 and the second liquid outlet 400 are connected to the liquid outlet cavity 200 through the liquid outlet groove 1200. In the disclosed embodiment, the guide hole 600, the liquid separator 24 and the sealing assembly 23 are arranged on the inner frame 213. The connecting column 21211 is arranged on the main body 2121. A driving protrusion 2111 is arranged on the cover 211 to facilitate driving the cover mechanism 20 to rotate relative to the rear cover mechanism 10.

[0126] In the exemplary embodiment, please combine Figure 6 , Fig. 9 , Fig.12 , Fig.14 and Fig.19 , the rear cover mechanism 10 includes a rear cover assembly 12 and an elastic assembly 13. The elastic assembly 13 is arranged on the rear cover assembly 12. The elastic assembly 13 is provided with a through hole 1300, the through hole 1300 is connected to the liquid inlet channel 100, and the elastic assembly 13 elastically abuts against the liquid separator 24. During the rotation of the face shell mechanism 20 relative to the rear cover mechanism 10, the elastic assembly 13 can slide relative to the liquid separator 24, so that the through hole 1300 is connected to the first flow channel hole 1001 to reduce the liquid flow rate, or the through hole 1300 is connected to 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 assembly 13 can always abut against the liquid separator 24 to prevent the liquid from being discharged from between the elastic assembly 13 and the liquid separator 24, so that the liquid has a certain flow direction under the restriction of the elastic assembly 13 and the liquid separator 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 member 131 and an elastic member 132. The flexible member 131 can elastically abut against the liquid separation member 24. The flexible member 131 can better fit the liquid separation member 24 by deforming itself, thereby improving the sealing between the elastic component 13 and the liquid separation member 24. The rear cover component 12 includes a rear cover 121, a liquid inlet pipe 122 and a joint 123. The liquid inlet pipe 122 is arranged on the rear cover 121 and connected to the joint 123. The liquid inlet channel 100 passes through the liquid inlet pipe 122 and the joint 123 in sequence. The joint 123 is provided with a mounting groove 1400 connected to the liquid inlet channel 100. The elastic member 132 is installed in the mounting groove 1400 and supported between the joint 123 and the flexible member 131, so as to further improve the elastic abutment force of the flexible member 131 on the liquid separation member 24, thereby further improving the sealing stability between the elastic component 13 and the liquid separation member 24. The through hole 1300 passes through the flexible member 131 and communicates with the liquid inlet channel 100 through the mounting groove 1400. The flexible member 131 may be made of, but not limited to, rubber material. The elastic member 132 may be, but not limited to, a metal spring member and a plastic spring.

[0128] Please combine Figure 23 to Figure 28 Now, the liquid outlet system provided by another embodiment of the present disclosure is described. The structure of the liquid outlet system of the embodiment of the present disclosure is as follows: Figures 1 to 22 The embodiments shown are basically the same, except that the insertion portion 321 of the liquid outlet system of the embodiment of the present disclosure has a tip 3211 facing the corresponding first liquid outlet hole 300. The movable component 30 is also configured to be able to move relative to the surface shell mechanism 20, so that the tip 3211 is at least partially accommodated in the corresponding first liquid outlet hole 300, and the tip 3211 is spaced apart from the corresponding liquid outlet portion 2122. In this way, the liquid can be discharged from the gap between the tip 3211 and the corresponding liquid outlet portion 2122, and the flow area of ​​the above gap is close to the flow area of ​​the second liquid outlet hole 400. By utilizing the wall attachment effect of the tip 3211, the liquid discharged from the above gap can be gathered into a liquid flow, and the shape is similar to that of the liquid discharged from the second liquid outlet hole 400. As a result, the above gap and multiple second liquid outlet holes 400 discharge liquid at the same time, forming a large rain of liquid discharge with multiple fine liquid outlet columns.

[0129] In an exemplary embodiment, please continue to refer to Figure 23 to Figure 28, one of the rear cover mechanism 10 and the face shell mechanism 20 is provided with a positioning assembly 40, and the other is provided with a positioning member, the positioning member is provided with a first positioning portion 700, a second positioning portion 800 and a third positioning portion 1500, and the first positioning portion 700, the second positioning portion 800 and the third positioning portion 1500 are arranged to cooperate with the positioning assembly 40 for positioning when the movable component 30 is connected with or separated from the plurality of liquid outlet portions 2122 or the tip 3211 is at least partially accommodated in the corresponding first liquid outlet hole 300, and the tip 3211 is arranged at intervals with the corresponding liquid outlet portion 2122 (the first liquid outlet hole 300 is in a partially shielded state), so as to sense whether the face shell mechanism 20 moves to the preset position, so as to realize that the first liquid outlet hole 300 corresponding to each preset position is in a blocked state (such as Fig. 27 As shown), open state (as shown Fig.23 as shown) or partially obscured (as shown Fig.25 as shown) for 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 on one of the rear cover mechanism 10 and the face shell mechanism 20. The mounting component 41 is provided with a mounting space. The abutting component 42 is partially located in the mounting space and can be slidably connected with the positioning member. The elastic component 43 is installed in the mounting space and can abut the abutting component 42 against the positioning member. In this way, the elastic component 43 can be disposed to make the abutting component 42 and the positioning member fit more closely, avoiding a gap between the abutting component 42 and the positioning member, which causes an abnormal sound when the abutting component 42 slides against the positioning member.

[0131] In the embodiment of the present disclosure, the first positioning portion 700, the second positioning portion 800 and the third positioning portion 1500 are all groove structures, and the elastic component 43 can also make the abutting component 42 relatively stably in the groove structure, thereby improving the accuracy of position perception. The elastic component 43 can be, but is not limited to, a metal spring component or a plastic spring. In the embodiment of the present disclosure, the mounting component 41 is a columnar structure and is disposed on the rear cover mechanism 10. The positioning member is disposed on the liquid separation member 24.

[0132] Please combine Fig.23 , Fig. 27 and Fig.28After the insertion part 321 blocks the first liquid outlet hole 300, the friction between the insertion part 321 and the multiple liquid outlet parts 2122 can drive the multiple liquid outlet parts 2122 to convex or concave deformation 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. In the above-mentioned convex and concave deformation process, the scale formed on the hole wall of the liquid outlet hole (the first liquid outlet hole 300 and the second liquid outlet hole 400) can be further loosened, so that it is easy to be washed away by the liquid passing through the liquid outlet hole (the first liquid outlet hole 300 and the second liquid outlet hole 400), thereby preventing the liquid outlet hole (the first liquid outlet hole 300 and the second liquid outlet hole 400) from being blocked by scale.

[0133] In an exemplary embodiment, the movable assembly 30 can also be driven by the hydraulic pressure of the liquid entering the liquid outlet device to move relative to the cover mechanism 20. The movable assembly 30 can also be driven by an electric control mechanism disposed in the rear cover mechanism 10 or the cover mechanism 20.

[0134] In an exemplary embodiment, if Fig.26 As shown, the liquid separation member 24 can also be combined with the housing assembly 21 to form a third liquid separation channel 1600 . The third liquid separation channel 1600 is connected to the liquid outlet cavity 200 . The liquid separation member 24 is provided with a third channel hole 1601 connected to the third liquid separation channel 1600 .

[0135] During the rotation of the face shell mechanism 20 relative to the rear cover mechanism 10, the liquid inlet channel 100 can also be connected to the third channel hole 1601, so that the liquid flow rate from the liquid inlet channel 100 into the liquid outlet cavity 200 is moderate, and the face shell mechanism 20 can drive the movable component 30, so that the tip 3211 is at least partially accommodated in the corresponding first liquid outlet hole 300, and the tip 3211 is spaced apart from the corresponding liquid outlet portion 2122. In this way, when the first liquid outlet hole 300 is in a partially shielded state, by adjusting the liquid flow rate from the liquid inlet channel 100 into the liquid outlet cavity 200, it can ensure that the large silk rain liquid is softer and more delicate, and it can avoid that the liquid pressure is too high after the first liquid outlet hole 300 is partially shielded, causing the liquid outlet portion 2122 to be damaged by the liquid pressure.

[0136] In this way, by disposing the first liquid separation channel 1000 , the second liquid separation channel 1100 and the third liquid separation channel 1600 , the liquid flow rate can be conveniently controlled.

[0137] Please combine Figure 29 to Figure 45 Now, the liquid outlet system provided by another embodiment of the present disclosure is described. The structure of the liquid outlet system of the embodiment of the present disclosure is as follows: Figures 1 to 22The embodiments shown are basically the same, except that the liquid outlet portion 2122 of the liquid outlet system of the embodiment of the present disclosure is further provided with an abutment surface 21221, and the number of liquid outlet holes is multiple, including multiple second liquid outlet holes 400, and the multiple liquid outlet holes 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 can abut against the abutting surface 21221, and drives the liquid outlet 2122 to protrude to a side away from the movable component 30, so that the liquid outlet directions of the plurality of second liquid outlet holes 400 do not intersect, and the movable component 30 is separated from the plurality of liquid outlets 2122 to reset the liquid outlet 2122. In the disclosed embodiment, the liquid outlet 2122 can be made of an elastic material.

[0139] The liquid discharge device of the above solution is applied to the liquid discharge system. In addition to making the liquid discharge system have excellent cleaning performance, it can also reduce the degree of sparseness and looseness of the liquid discharge part 2122 and improve the liquid discharge effect. Specifically, the liquid discharge device includes a rear cover mechanism 10 provided with a liquid inlet channel 100, a surface shell mechanism 20 installed on the rear cover mechanism 10, and a movable component 30. The surface shell mechanism 20 is provided with a liquid discharge cavity 200 and a plurality of liquid discharge parts 2122. The liquid inlet channel 100 is connected with the liquid outlet cavity 200, and the liquid outlet portion 2122 is provided with an abutment surface 21221 and a plurality of second liquid outlet holes 400. The second liquid outlet holes 400 are connected with the liquid outlet cavity 200, and the plurality of second liquid outlet holes 400 are arranged around the abutment surface 21221, and the liquid outlet directions of the plurality of second liquid outlet holes 400 intersect, so that the liquid discharged from the plurality of second liquid outlet holes 400 can converge into a liquid flow, forming a new liquid outlet pattern and enhancing the impact of the liquid outlet. The movable component 30 is connected to the multiple liquid outlets 2122 and can abut against the abutment surface 21221, and drives the liquid outlet 2122 to bulge toward the side away from the movable component 30, so that the liquid outlet directions of the multiple second liquid outlet holes 400 do not intersect, thereby changing the liquid outlet directions of the multiple second liquid outlet holes 400 from converging to parallel, or even further away from each other, avoiding the convergence of the liquid outlets of the multiple second liquid outlet holes 400 when the liquid is discharged in a drizzle, and can expand the liquid outlet area of ​​the liquid outlet device, thereby improving the drizzle liquid discharge effect. The movable component 30 is separated from the multiple liquid outlets 2122, that is, separated from the abutment surface 21221, and can reset the liquid outlet 2122, so that the liquid discharged from the multiple second liquid outlet holes 400 converges into a liquid flow again. In this way, the silk rain liquid and the impact liquid have the same second liquid outlet hole 400, thereby reducing the number of openings in the liquid outlet part 2122, improving the strength of the liquid outlet part 2122, and avoiding the liquid outlet part 2122 from being sparse and loose, thereby improving the liquid outlet effect.

[0140] Furthermore, different liquid outlet modes have the same second liquid outlet hole 400, so that the liquid outlet position does not change before and after the liquid outlet mode is switched. The switching of the liquid outlet mode does not affect the liquid outlet of the full shell mechanism 20 of the liquid outlet device, thereby avoiding the liquid outlet positions of different liquid outlet modes being dispersed in different liquid outlet areas, so that the liquid outlet device in the embodiment of the present disclosure has a larger liquid outlet area, ensuring that a better shower effect can be achieved before and after the liquid outlet mode is switched.

[0141] In addition, the liquid outlet portion 2122 protrudes toward the side away from the movable component 30, which can deform the hole wall of the second liquid outlet hole 400, thereby loosening the scale formed on the hole wall and facilitating flushing by the liquid passing through the second liquid outlet hole 400, thereby preventing the second liquid outlet hole 400 from being blocked by scale.

[0142] In the exemplary embodiment, please combine Fig.32 , Fig.34 , Fig.38 , Fig.40 and Fig.42 The movable component 30 includes a main body 31 and a plurality of abutment structures 32a, wherein the plurality of abutment structures 32a are arranged on the main body 31 and correspond to the plurality of abutment surfaces 21221 one by one, and the main body 31 is slidably connected to the surface shell mechanism 20, and the abutment structure 32a can approach and abut the corresponding abutment surface 21221 with the main body 31 and drive the corresponding liquid outlet portion 2122 to protrude to the side away from the movable component 30, or reset with the main body 31 to reset the liquid outlet portion 2122.

[0143] In this way, by driving the main body 31, multiple abutment structures 32a can be synchronously abutted against the corresponding abutment surfaces 21221, driving the corresponding liquid outlet portion 2122 to protrude to the side away from the movable component 30, so that the liquid outlet directions of multiple liquid outlet holes (second liquid outlet holes 400) do not intersect, forming a silk rain liquid outlet; or multiple abutment structures 32a are synchronously separated from the corresponding abutment surfaces 21221, so that the liquid outlet directions of multiple liquid outlet holes intersect again, forming an impact-feeling liquid outlet, thereby ensuring the consistency of the liquid outlet switching.

[0144] In an exemplary embodiment, please continue to refer to Fig.31, the abutting structure 32a has a small end 32a1 facing the abutting surface 21221 and a large end 32a2 away from the abutting surface 21221 in a cross section parallel to the moving direction of the abutting structure 32a. In this way, by using the small size of the small end 32a1, the abutting structure 32a can be easily abutted against the abutting surface 21221 without affecting the liquid entering the liquid outlet hole (the second liquid outlet hole 400), and the small end 32a1 with a small size can also facilitate the liquid outlet part 2122 to quickly reach a preset protruding size, so that the liquid outlet directions of multiple liquid outlet holes do not intersect, achieving a rain-like liquid outlet effect. By utilizing the larger size of the large end portion 32a2, the connection area between the abutment structure 32a and the main body 31 can be increased, the strength of the abutment structure 32a can be increased, and the structural stability of the abutment structure 32a can be improved, thereby ensuring that the abutment structure 32a can stably abut against the abutment surface 21221, thereby ensuring the stability of the protruding size and shape of the liquid outlet portion 2122 and ensuring the silky rain liquid discharge effect.

[0145] The side of the small end portion 32a1 facing the abutting surface 21221 has a passivated surface to avoid poking or scratching the abutting surface 21221 and to increase the life of the liquid outlet 2122. It can be understood that in other embodiments, the side of the small end portion 32a1 facing the abutting surface 21221 can also be a plane or an inclined surface, etc., so as to change the shape of the liquid outlet 2122 protruding away from the movable component 30.

[0146] In the exemplary embodiment, please combine Fig.32 , Fig.34 , Fig.38 , Fig.40 and Fig.42 The body 31 is provided with a guide member 311, and the guide member 311 cooperates with the cover mechanism 20 to limit the movement direction of the movable assembly 30. In this way, the setting of the guide member 311 can further increase the connection area between the body 31 and the cover mechanism 20, and improve the connection stability. In addition, the guide cooperation between the guide member 311 and the cover mechanism 20 can ensure the movement accuracy of the movable assembly 30, and further ensure the abutment accuracy between the movable assembly 30 and the multiple abutment surfaces 21221.

[0147] In an exemplary embodiment, if Fig.32 , Fig.38 and Fig.41As shown, the rear cover mechanism 10 has a boss 11, and the face shell mechanism 20 is provided with a guide hole 600, and the guide member 311 is penetrated by the guide hole 600. The face 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, and then the abutment structure 32a can approach the corresponding abutment surface 21221 with the body 31 and drive the corresponding liquid outlet 2122 to protrude to the side away from the movable component 30. In this way, through the provision of the guide hole 600, the guide member 311 can contact the boss 11 through the guide hole 600, so that the guide member 311 can change the distance between the movable component 30 and the plurality of liquid outlets 2122 according to the degree of protrusion of the boss 11 toward the side of the face shell mechanism 20 during the sliding process along the boss 11, until the abutment structure 32a drives the corresponding liquid outlet 2122 to protrude to the side away from the movable component 30. The extension direction of the boss 11 matches the rotation trajectory of the guide member 311 to ensure that the guide member 311 can always contact the boss 11 during the movement of the movable component 30 toward the multiple liquid outlets 2122, thereby ensuring the smooth movement of the movable component 30 toward the multiple liquid outlets 2122.

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

[0149] For example, Fig.42 and Fig.43 As shown, the movable component 30 can be driven by the pressing structure 33 to move relative to the face shell mechanism 20. Correspondingly, the face shell mechanism 20 can be fixedly connected to the rear cover mechanism 10. The face shell mechanism 20 can also be rotatably connected to the rear cover mechanism 10, and the pressing structure 33 can separately or jointly drive the movable component 30 to move relative to the face shell mechanism 20. In some embodiments, the movement of the movable component 30 relative to the face shell mechanism 20 can also drive the face shell mechanism 20 to move relative to the rear cover mechanism 10. In other embodiments, the movement of the movable component 30 relative to the face shell mechanism 20 can also be driven by the hydraulic pressure of the liquid entering the liquid outlet device. The movement of the movable component 30 relative to the face shell mechanism 20 can also be driven by an electric control mechanism arranged in the rear cover mechanism 10 or the face shell mechanism 20.

[0150] In an exemplary embodiment, if Fig.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 cooperate with the inclined surface 111. In this way, by providing the guide surface 3111, it is possible to ensure that the cooperation between the guide member 311 and the boss 11 is smoother. During the rotation of the cover mechanism 20 relative to the rear cover mechanism 10, the guide surface 3111 can slide along the inclined surface 111, so that the abutment structure 32a can approach the corresponding abutment surface 21221 with the body 31 and drive the corresponding liquid outlet 2122 to protrude to the side away from the movable component 30.

[0151] In the exemplary embodiment, please combine Fig.32 , Fig.36 and Fig.40 One of the rear cover mechanism 10 and the face shell mechanism 20 is provided with a positioning assembly 40, and the other is provided with a positioning member, the positioning member is provided with a first positioning portion 700 and a second positioning portion 800, and the first positioning portion 700 and the second positioning portion 800 are configured to cooperate with the positioning assembly 40 for positioning when the movable assembly 30 is connected to or separated from the multiple liquid outlets 2122, respectively.

[0152] In the embodiment of the present disclosure, the first positioning portion 700 and the second positioning portion 800 are configured to cooperate with the positioning assembly 40 to perform positioning when the liquid outlet portion 2122 is in a protruding state or a reset state, respectively, so as to be able to sense whether the surface shell mechanism 20 moves to the preset position, thereby realizing the sensing that the liquid outlet portion 2122 corresponding to each preset position is in a protruding state or a 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 on one of the rear cover mechanism 10 and the face shell mechanism 20. The mounting component 41 is provided with a mounting space. The abutting component 42 is partially located in the mounting space and can be slidably connected with the positioning member. The elastic component 43 is installed in the mounting space and can abut the abutting component 42 against the positioning member. In this way, the elastic component 43 can be disposed to make the abutting component 42 and the positioning member fit more closely, avoiding a gap between the abutting component 42 and the positioning member, which causes an abnormal sound when the abutting component 42 slides against the positioning member.

[0154] In the embodiment of the present disclosure, the first positioning portion 700 and the second positioning portion 800 are groove structures, and the elastic component 43 can also make the abutting component 42 relatively stably in the groove structure, thereby improving the accuracy of position sensing. The elastic component 43 can be, but is not limited to, a metal spring component or a plastic spring. In the embodiment of the present disclosure, the mounting component 41 is a columnar structure and is disposed on the rear cover mechanism 10. The positioning component is disposed on the liquid separation component 24.

[0155] In the exemplary embodiment, please combine Fig.35 and Fig.41The face shell 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. A plurality of liquid outlets 2122 are provided on the shell assembly 21. The reset member 22 is provided on the shell assembly 21 or the rear cover mechanism 10. The reset member 22 is configured to generate a driving force for resetting the movable assembly 30, so that the plurality of abutment structures 32a can be reset along with the body 31. In the disclosed embodiment, the reset member 22 is a coil 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 makes the movable assembly 30 approach the plurality of liquid outlets 2122. The body 31 can compress the reset member 22, generate a driving force for resetting the movable assembly 30, and make the guide member 311 fit tightly with the boss 11, thereby ensuring the matching accuracy between the guide member 311 and the boss 11. When the guide member 311 slides along the boss 11 and the protrusion of the boss 11 toward the side of the housing mechanism 20 gradually decreases, the reset member 22 can drive the movable assembly 30 away from the plurality of liquid outlets 2122 to achieve the reset of the movable assembly 30. In addition, in some exemplary embodiments, the reset member 22 can also be a magnetic member, which generates a magnetic attraction force on the movable assembly 30 to drive the movable assembly 30 to reset.

[0156] In an exemplary embodiment, please continue to refer to Fig.35 and Fig.41 The reset member 22 is a coil spring, which is clamped between the movable assembly 30 and the housing assembly 21 and is positioned and connected to at least one of the movable assembly 30 and the housing assembly 21 to ensure the stability of the position of the reset member 22, thereby ensuring the directional accuracy of the reset driving force of the movable assembly 30. In the disclosed embodiment, the housing assembly 21 is provided with a connecting column 21211, and the movable assembly 30 is provided with a connecting groove 900 arranged opposite to the connecting column 21211. One end of the reset member 22 is sleeved on the connecting column 21211, and the other end is accommodated in the connecting groove 900. The body 31 is close to the multiple liquid outlets 2122 to compress the reset member 22 to generate a driving force for resetting the movable assembly 30.

[0157] In the exemplary embodiment, please combine Fig.34 , Fig.38 and Fig.40The face shell mechanism 20 further includes a sealing assembly 23, which is disposed on the housing assembly 21 and sleeved on the guide member 311, and is slidably sealed with the guide member 311. Thus, the sealing assembly 23 can ensure the sealing of the guide hole 600, and prevent the liquid from overflowing from between the guide member 311 and the guide hole 600. In addition, the sealing assembly 23 can also increase the connection area between the guide member 311 and the housing assembly 21, and improve the guiding stability between the guide member 311 and the housing assembly 21. The sealing assembly 23 includes a cover body 231 and a sealing member 232. The sealing member 232 is sleeved on the guide member 311 and accommodated in a receiving groove arranged on the shell assembly 21, and the sealing member 232 is arranged between the guide member 311 and the shell assembly 21. The cover body 231 is connected to the shell assembly 21 and sleeved on the guide member 311. The cover body 231 can cover the receiving groove to prevent the sealing member 232 from moving out of the receiving groove. The guide member 311 passes through the sealing member 232 and extends from the cover body 231 so as to be able to contact the boss 11.

[0158] In the exemplary embodiment, please combine Fig.33 , Fig.35 , Fig.37 , Fig.38 and Fig.40 The shell mechanism 20 further includes a liquid separator 24. The liquid separator 24 is disposed on the housing assembly 21 and encloses the housing assembly 21 to form a first liquid separator channel 1000 and a second liquid separator channel 1100. The first liquid separator channel 1000 and the second liquid separator channel 1100 are respectively connected to the liquid outlet cavity 200. The liquid separator 24 is provided with a first channel hole 1001 connected to the first liquid separator channel 1000 and a second channel hole 1101 connected to the second liquid separator channel 1100. The first positioning portion 700 and the second positioning portion 800 are disposed on the liquid separator 24.

[0159] During the rotation of the face shell mechanism 20 relative to the rear cover mechanism 10, the liquid inlet channel 100 can be connected to the first channel hole 1001 to reduce the liquid flow rate entering the liquid outlet cavity 200 from the liquid inlet channel 100, and the face shell mechanism 20 can drive the movable component 30 to connect with multiple liquid outlets 2122 to drive the liquid outlet 2122 to bulge to the side away from the movable component 30; or the liquid inlet channel 100 can be connected to the second channel hole 1101 to increase the liquid flow rate, and the face shell mechanism 20 can drive the movable component 30 to separate from multiple liquid outlets 2122, that is, from multiple abutment surfaces 21221, so that the liquid outlet 2122 is reset. In this way, when the silk rain is discharged, by reducing the liquid flow rate entering the liquid outlet cavity 200 from the liquid inlet channel 100, it can be ensured that the silk rain is discharged more softly and delicately. And when the impact feeling is discharged, the impact force of the liquid discharged from the liquid outlet hole can be guaranteed by increasing the liquid flow rate, and the impact feeling of the liquid discharge is further guaranteed.

[0160] During the rotation of the face shell mechanism 20 relative to the rear cover mechanism 10, the liquid inlet channel 100 can be connected to the first channel hole 1001 to reduce the liquid flow rate from the liquid inlet channel 100 into the liquid outlet cavity 200, or connected to the second channel hole 1101 to increase the liquid flow rate. In this way, the liquid inlet channel 100 is connected to the first liquid distribution channel 1000 and the second liquid distribution channel 1100 respectively, so as to facilitate the control of the liquid flow rate.

[0161] Please combine Fig.29 , Figures 32 to 42 The housing assembly 21 includes a face cover 211, a liquid outlet component 212 and an inner frame 213. The face cover 211 is provided with a plurality of mounting holes. A plurality of liquid outlets 2122 are mounted one by one with the plurality of mounting holes to ensure the stability of the position of the liquid outlet 2122 relative to the face cover 211. The liquid outlet component 212 is arranged on one side of the face cover 211 and is surrounded by the inner frame 213 to form a liquid outlet cavity 200. The inner frame 213 is connected to the face cover 211 and fixes the liquid outlet component 212 to the face cover 211. The liquid outlet component 212 includes a body 2121 and a plurality of liquid outlets 2122 arranged on the body 2121. The liquid outlet component 2122 is a columnar structure, including a circumferential wall and a liquid outlet surface. The circumferential wall and the liquid outlet surface are surrounded by a liquid outlet groove 1200 communicated with the liquid outlet cavity 200. The liquid outlet hole is communicated with the liquid outlet cavity 200 through the liquid outlet groove 1200. In the disclosed embodiment, the guide hole 600, the liquid separator 24 and the sealing assembly 23 are arranged on the inner frame 213. The connecting column 21211 is arranged on the main body 2121. The front cover 211 is provided with a driving protrusion 2111 to facilitate driving the front shell mechanism 20 to rotate relative to the rear cover mechanism 10.

[0162] In the exemplary embodiment, please combine Fig.33 , Fig.37 and Fig.41 , the rear cover mechanism 10 includes a rear cover assembly 12 and an elastic assembly 13. The elastic assembly 13 is arranged on the rear cover assembly 12. The elastic assembly 13 is provided with a through hole 1300, the through hole 1300 is connected to the liquid inlet channel 100, and the elastic assembly 13 elastically abuts against the liquid separator 24. During the rotation of the face shell mechanism 20 relative to the rear cover mechanism 10, the elastic assembly 13 can slide relative to the liquid separator 24, so that the through hole 1300 is connected to the first flow channel hole 1001 to reduce the liquid flow rate, or the through hole 1300 is connected to 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 assembly 13 can always abut against the liquid separator 24 to prevent the liquid from being discharged from between the elastic assembly 13 and the liquid separator 24, so that the liquid has a certain flow direction under the restriction of the elastic assembly 13 and the liquid separator 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 member 131 and an elastic member 132. The flexible member 131 can elastically abut against the liquid separation member 24. The flexible member 131 can better fit the liquid separation member 24 by deforming itself, thereby improving the sealing between the elastic component 13 and the liquid separation member 24. The rear cover component 12 includes a rear cover 121, a liquid inlet pipe 122 and a joint 123. The liquid inlet pipe 122 is arranged on the rear cover 121 and connected to the joint 123. The liquid inlet channel 100 passes through the liquid inlet pipe 122 and the joint 123 in sequence. The joint 123 is provided with a mounting groove 1400 connected to the liquid inlet channel 100. The elastic member 132 is installed in the mounting groove 1400 and supported between the joint 123 and the flexible member 131, so as to further improve the elastic abutment force of the flexible member 131 on the liquid separation member 24, thereby further improving the sealing stability between the elastic component 13 and the liquid separation member 24.

The flexible member 131 may be made of, but not limited to, rubber material. The elastic member 132 may be, but not limited to, a metal spring member and a plastic spring.

[0164] In the exemplary embodiment, please combine Figure 42 to Figure 45 The shell mechanism 20 further includes a liquid separator 24. The liquid separator 24 is disposed on the housing assembly 21 and encloses the housing assembly 21 to form a first liquid separator channel 1000 and a second liquid separator channel 1100. The first liquid separator channel 1000 and the second liquid separator channel 1100 are respectively connected to the liquid outlet cavity 200. The liquid separator 24 is provided with a first channel hole 1001 connected to the first liquid separator channel 1000 and a second channel hole 1101 connected to the second liquid separator channel 1100.

[0165] The liquid outlet device further includes a switching assembly 50, which is disposed on the rear cover mechanism 10 and is configured to selectively introduce the liquid inlet channel 100 into one of the first channel hole 1001 and the second channel hole 1101 to change the liquid flow rate from the liquid inlet channel 100 into the liquid outlet cavity 200. For example, the liquid outlet portion 2122 protrudes toward the side away from the movable component 30, and when it is in the state of drizzle liquid outlet, the switching assembly 50 can connect the liquid inlet channel 100 with the first channel hole 1001 to reduce the liquid flow rate from the liquid inlet channel 100 into the liquid outlet cavity 200; when the liquid outlet portion 2122 is reset and in the state of impact liquid outlet, the switching assembly 50 can connect the liquid inlet channel 100 with the second channel hole 1101 to increase the liquid flow rate from the liquid inlet channel 100 into the liquid outlet cavity 200. In the embodiment of the present disclosure, the switching assembly 50 includes a driving member 51 and a switching member 52. The driving member 51 can be driven to drive the switching member 52 to rotate, so as to seal one of the first flow channel hole 1001 and the second flow channel hole 1101, and connect the other with the liquid inlet flow channel 100. The driving member 51 can be, but is not limited to, a push button, a roller, a button or a handle.

[0166] Please combine Figures 46 to 66 Now, the liquid outlet system provided by another embodiment of the present disclosure is described. The structure of the liquid outlet system of the embodiment of the present disclosure is as follows: Figures 1 to 22 The embodiments shown are basically the same, except that the surface shell mechanism 20 of the liquid outlet system of the disclosed embodiment is movably mounted on the rear cover mechanism 10. The liquid outlet includes a first liquid outlet 300, but does not include a plurality of second liquid outlets 400.

[0167] The face shell mechanism 20 is configured to be able to move relative to the rear cover mechanism 10, reduce the liquid flow rate from the liquid inlet channel 100 into the liquid outlet cavity 200 and drive the movable component 30 to connect with the multiple liquid outlet portions 2122 to reduce the flow area of ​​the multiple liquid outlet holes (first liquid outlet holes 300); or increase the liquid flow rate and drive the movable component 30 to separate and reset from the multiple liquid outlet portions 2122. In the embodiment of the present disclosure, the multiple liquid outlet holes include multiple first liquid outlet holes 300.

[0168] The liquid outlet device of the above scheme is applied to the liquid outlet system. In addition to making the liquid outlet system have excellent cleaning performance, it can also avoid the small diameter of the liquid outlet hole (the first liquid outlet hole 300), reduce the probability of clogging and scaling of the liquid outlet hole, and meet the needs of some users for the impact of liquid outlet. Specifically, the liquid outlet device includes a rear cover mechanism 10 provided with a liquid inlet channel 100, a movable component 30, and a face shell mechanism 20 movably mounted on the rear cover mechanism 10. The face shell mechanism 20 is provided with a liquid outlet cavity 200 and a plurality of liquid outlet portions 2122. After the liquid enters the liquid outlet cavity 200 from the liquid inlet channel 100, it is discharged from the liquid outlet holes on the plurality of liquid outlet portions 2122 respectively. The face shell mechanism 20 is configured to be able to move relative to the rear cover mechanism 10, reduce the liquid flow rate entering the liquid outlet cavity 200 from the liquid inlet channel 100 and drive the movable component 30 to connect with multiple liquid outlets 2122, so as to reduce the flow area of ​​multiple liquid outlet holes, form a drizzle of liquid outflow, and at the same time, reduce the liquid flow rate to ensure the softness and fineness of the drizzle of liquid outflow, avoid the reduction of the flow area of ​​the liquid outlet hole resulting in excessive liquid pressure, and cause the liquid outlet part 2122 to be damaged by the liquid pressure. The face shell mechanism 20 is configured to be able to move relative to the rear cover mechanism 10, increase the liquid flow rate and drive the movable component 30 to reset, so that the liquid pressure and the flow area of ​​the liquid outlet hole are increased, which is convenient for the discharge of impurities in the liquid, and is not easy to block the liquid outlet hole, and the impact force of the liquid is large, which is convenient for washing away the original scale and bringing the impact feeling of liquid outflow.

[0169] In the exemplary embodiment, please combine Fig.46 , Fig.47 , Fig.51 , Fig.55 and Fig.56The movable component 30 includes a body 31 and a plurality of shielding structures 32c. The plurality of shielding structures 32c are arranged on the body 31 and correspond to the plurality of liquid outlets 2122. The body 31 is slidably connected to the surface shell mechanism 20. The shielding structures 32c can approach the corresponding liquid outlet 2122 with the body 31 and connect with the corresponding liquid outlet 2122 to partially shield the corresponding liquid outlet hole and reduce the flow area of ​​the corresponding liquid outlet hole; or reset with the body 31. In this way, by driving the body 31, the plurality of shielding structures 32c can be synchronously connected with the corresponding liquid outlet 2122 to reduce the flow area of ​​the corresponding liquid outlet hole; or the plurality of shielding structures 32c can be synchronously separated from the corresponding liquid outlet 2122 to increase the flow area of ​​the corresponding liquid outlet hole, so that the flow area of ​​each liquid outlet hole can be changed synchronously to ensure the consistency of the liquid discharge. Moreover, the shielding structure 32c only changes the flow area size of the corresponding liquid outlet hole to achieve the switching of the liquid outlet mode (silky rain liquid outlet and impact liquid outlet), while the position of the liquid outlet hole does not change, so 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 parts 2122 of different liquid outlet modes being dispersed in different liquid outlet areas, so that the liquid outlet device in the embodiment of the present application has a larger liquid outlet area, ensuring that a better shower effect can be achieved before and after the liquid outlet mode is switched.

[0170] In the exemplary embodiment, please combine Fig.46 , Fig.47 , Fig.51 , Figures 55 to 60 , the shielding structure 32c can be at least partially inserted into the corresponding liquid outlet hole, so that the scale formed on the liquid outlet hole can be removed by the insertion action of the shielding structure 32c, further improving the descaling effect. The shielding structure 32c can be at least partially inserted into the corresponding liquid outlet hole, and at least one flow area 1700 can be formed between the shielding structure 32c and the hole wall forming the corresponding liquid outlet hole to partially shield the corresponding liquid outlet hole. The flow area 1700 is a part of the liquid outlet hole (the first liquid outlet hole 300). Compared with the liquid outlet hole, the flow area 1700 has a smaller flow area and can form a silky liquid outlet.

[0172] In the embodiment of the present application, the number of the first protrusions 32c1 is four and they are evenly distributed around the liquid flow direction, and together with the hole wall, they form four flow areas 1700, so that the liquid outlet hole changes from a single hole to a four-hole rain-like liquid outlet. The cross-section of the shielding structure 32c along the direction perpendicular to the liquid flow direction is equal, and a first guide groove 32c10 extending into the liquid outlet hole can be formed between adjacent first protrusions 32c1 to guide the liquid and facilitate the liquid to pass smoothly through the flow area 1700. The cross-sectional shape of the liquid outlet hole along the direction perpendicular to the liquid flow direction can be circular (such as Fig.58 As shown), regular shapes such as ellipse, triangle, square, trapezoid, parallelogram or hexagon, or irregular shapes such as Fig.62 As shown, the liquid outlet includes a main body part 301 and a branch part 302 arranged around the main body part 301.

In this way, the scale formed on the liquid outlet hole can be removed by the inserting action of the inserting portion 32c2, further improving the descaling effect. The second protrusion 32c4 abuts against the corresponding liquid outlet portion 2122, which can limit the size of the inserting portion 32c2 protruding from the liquid outlet portion 2122, thereby reducing the risk of scratching or stabbing the user.

[0174] The inserting portion 32c2 is spaced apart from the corresponding hole wall to form a flow area 1700, and at least one second protrusion 32c4 can change the number of connected areas between the liquid outlet cavity 200 and the corresponding flow area 1700 and / or the cross-sectional shape and size along the direction perpendicular to the liquid flow. In this way, the second protrusion 32c4 can shield the flow area 1700 on the upstream side of the flow area 1700, and the number and shape of the second protrusions 32c4 and the space surrounded by the adjacent second protrusions 32c4 can be changed to change the number of connected areas between the liquid outlet cavity 200 and the corresponding flow area 1700 and / or the cross-sectional shape and size along the direction perpendicular to the liquid flow.

[0175] In the embodiment of the present application, the number of the second protrusions 32c4 is four and they are evenly distributed around the liquid flow direction, and can enclose four second guide grooves 32c40 connected to the flow area 1700, so that the liquid outlet hole changes from a single hole to a four-hole rain-like liquid outlet. In addition, the second guide grooves 32c40 can guide the liquid to facilitate the liquid to pass through the flow area 1700 smoothly. The cross-sectional shape of the liquid outlet hole along the direction perpendicular to the liquid flow direction can be circular (such as Fig.58 ), regular shapes such as ellipse, triangle, square, trapezoid, parallelogram or hexagon, or irregular shapes such as Fig.62 As shown, the liquid outlet includes a main body part 301 and a branch part 302 arranged around the main body part 301. At this time, the insertion part 32c2 can be inserted only in the main body part 301, or can be inserted in the main body part 301 and the branch part 302 at the same time, and form a flow area 1700 in the main body part 301 and / or the branch part 302.

[0176] In an exemplary embodiment, if Figure 61 to Figure 64 As shown, the shielding structure 32c can abut against the corresponding liquid outlet portion 2122. The shielding structure 32c can shield the upstream side of the liquid outlet hole, and by changing the outer wall contour of the shielding structure 32c, the contour of the shielding area on the upstream side of the liquid outlet hole is changed, thereby changing the number of connecting areas between the liquid outlet cavity 200 and the corresponding liquid outlet hole and / or the cross-sectional shape and size along the direction perpendicular to the liquid flow direction. The cross-sectional shape of the liquid outlet hole along the direction perpendicular to the liquid flow direction can be circular (such as Fig.58 ), regular shapes such as ellipse, triangle, square, trapezoid, parallelogram or hexagon, or irregular shapes such as Fig.62 As shown, the liquid outlet includes a main body part 301 and a branch part 302 arranged around the main body part 301.

[0177] In the exemplary embodiment, please combine Fig.49 and Fig.53 The body 31 is provided with a guide member 311, and the guide member 311 cooperates with the face shell mechanism 20 to limit the movement direction of the movable component 30. In this way, the setting of the guide member 311 can further increase the connection area between the body 31 and the face shell mechanism 20, and improve the connection stability. In addition, the guiding cooperation between the guide member 311 and the face shell mechanism 20 can ensure the movement accuracy of the movable component 30, and then ensure the connection accuracy between the movable component 30 and the multiple liquid outlets 2122, and ensure that the shielding effect of the liquid outlet can reach the expected effect.

[0178] In the exemplary embodiment, please combine Fig.49 and Fig.53 , the rear cover mechanism 10 has a boss 11, the face shell mechanism 20 is provided with a guide hole 600, and the guide member 311 is passed through the guide hole 600. The face shell mechanism 20 moves relative to the rear cover mechanism 10 in a rotational motion. During the movement of the face shell mechanism 20 relative to the rear cover mechanism 10, the face shell mechanism 20 can drive the guide member 311 to slide along the boss 11, so that the movable component 30 can be connected with multiple liquid outlets 2122 to reduce the flow area of ​​the multiple liquid outlets. In this way, the guide hole 600 is provided to enable the guide member 311 to contact the boss 11 through the guide hole 600, so that the guide member 311 can change the distance between the movable component 30 and the multiple liquid outlets 2122 according to the degree of protrusion of the boss 11 to one side of the face shell mechanism 20 during the sliding process along the boss 11, until it is connected with the multiple liquid outlets 2122. The extension direction of the boss 11 matches the rotation trajectory of the guide member 311 to ensure that the guide member 311 can always contact the boss 11 during the movement of the movable component 30 toward the multiple liquid outlets 2122, thereby ensuring the smooth movement of the movable component 30 toward the multiple liquid outlets 2122.

[0179] The face shell mechanism 20 moves relative to the rear cover mechanism 10 by means of rotational motion, which can save the space required for the face shell mechanism 20 to move relative to the rear cover mechanism 10, making the liquid outlet device more compact. In order to facilitate the rotational motion of the face shell mechanism 20, a driving protrusion 2111 is also provided on the face shell mechanism 20, such as Figure 1 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 motion.

The guide member 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 moves in the opposite direction of the movement direction of the face shell mechanism 20 and is connected to the multiple liquid outlets 2122.

The reset member 22 is compressed, generating a driving force for resetting the movable component 30, and making the guide member 311 fit tightly with the boss 11, thereby ensuring the matching accuracy of the guide member 311 and the boss 11. When the guide member 311 slides along the boss 11 and the protrusion of the boss 11 toward the side of the housing mechanism 20 gradually decreases, the reset member 22 can drive the movable assembly 30 away from the plurality of liquid outlets 2122 to reset the movable assembly 30.

In addition, the sealing assembly 23 can also increase the connection area between the guide member 311 and the housing assembly 21, and improve the guiding stability between the guide member 311 and the housing assembly 21. The sealing assembly 23 includes a cover body 231 and a sealing member 232. The sealing member 232 is sleeved on the guide member 311 and accommodated in a receiving groove arranged on the shell assembly 21, and the sealing member 232 is arranged between the guide member 311 and the shell assembly 21.
