The liquid separator 1112 is detachably connected and installed in the shell 1111 or is integrally arranged with the shell 1111. The first connecting portion 11111, the second connecting portion 11112 and the third connecting portion 11113 are arranged on the shell 1111. The shell 1111 and the liquid separator 1112 are combined to form a liquid inlet cavity 300 connected to the liquid inlet channel 100. The first liquid outlet channel 201 can form a first liquid outlet hole 2011 on the liquid separator 1112. The second liquid outlet channel 202 can form a second liquid outlet hole 2021 on the liquid separator 1112.

[0059] The driving member 122 drives the movable assembly 112 to rotate relative to the body assembly 111 through the transmission member 123, so that at least one of the first liquid outlet hole 2011 and the second liquid outlet hole 2021 is disconnected from the liquid inlet cavity 300, or the first liquid outlet hole 2011 and the second liquid outlet hole 2021 are connected to the liquid inlet cavity 300. In this way, at least one of the first liquid outlet flow channel 201 and the second liquid outlet flow channel 202 is disconnected from the liquid inlet flow channel 100, or the first liquid outlet flow channel 201 and the second liquid outlet flow channel 202 are connected to the liquid inlet flow channel 100.

[0060] The driving member 122 drives the movable assembly 112 to rotate relative to the main body assembly 111 through the transmission member 123, so that at least one of the first liquid outlet channel 201 and the second liquid outlet channel 202 is disconnected from the liquid inlet channel 100, or the first liquid outlet channel 201 and the second liquid outlet channel 202 are connected to the liquid inlet channel 100. That is, the liquid outlet mode of the shower head 20, the liquid outlet mode of the top spray 30, the liquid outlet mode of neither the shower head 20 nor the top spray 30, and the liquid outlet mode of both the shower head 20 and the top spray 30. The liquid separation mechanism 11 is also provided with a fixed structure 70, which can be detachably connected to the shower head 20.

[0061] In summary, the implementation of the disclosed embodiment will have the following beneficial effects: the liquid separation device 10 of the above scheme is applied to the liquid outlet system. In addition to being able to realize the efficiency of switching the liquid outlet of different liquid outlet parts of the liquid outlet system, it can also facilitate the installation of the transmission member 123 and improve the assembly efficiency. Specifically, the liquid separation device 10 includes a liquid separation mechanism 11 and an operating mechanism 12. Among them, the liquid separation mechanism 11 includes a main body component 111 provided with a liquid inlet channel 100 and a plurality of liquid outlet channels 200 and a movable component 112 movably mounted on the main body component 111. The operating mechanism 12 includes a connecting member 121, a driving member 122 and a transmission member 123. Among them, the connecting member 121 includes a detachably connected outer shell 1211 and an inner core 1212, and the transmission member 123 is movably mounted between the outer shell 1211 and the inner core 1212, which can facilitate the installation of the transmission member 123 and improve the assembly efficiency. Furthermore, the outer shell 1211 and the inner core 1212 can restrict the transmission member 123 from both sides, improve the connection stability between the transmission member 123 and the connecting member 121, and thus ensure the transmission stability of the transmission member 123. The driving member 122 can drive the movable component 112 to rotate relative to the main body component 111 through the transmission member 123, so that at least one of the multiple liquid outlet channels 200 is disconnected from the liquid inlet channel 100, or multiple liquid outlet channels 200 are connected to the liquid inlet channel 100. In this way, by rotating the movable component 112 relative to the main body component 111, the connection state between the liquid inlet channel 100 and the multiple liquid outlet channels 200 can be changed, and then different liquid outlet channels 200 can be switched to discharge liquid or all liquid outlet channels 200 can be closed at the same time according to specific usage requirements.

[0062] The shell 1211 is detachably connected to the body component 111 to facilitate the disassembly and connection of the operating mechanism 12 and the liquid dispensing mechanism 11. After the inner core 1212 and the transmission member 123 are installed, they can be detachably connected to the body component 111 together with the driving member 122 and the shell 1211. After the inner core 1212 and the transmission member 123 are installed, they can also be detachably connected to the body component 111 first, and then detachably connected to the driving member 122 and the shell 1211 together with the body component 111. In this way, when the operating mechanism 12 or the liquid dispensing mechanism 11 is updated and upgraded, it is not necessary to open the mold of the liquid dispensing device 10 as a whole, thereby reducing the production cost caused by the update and upgrade. When the user wants to upgrade and change the operating mode or liquid dispensing mode, and when the operating structure or liquid dispensing structure is damaged and needs to be replaced, it is not necessary to purchase the liquid dispensing device 10 as a whole, which reduces the cost of upgrading, changing and replacing the liquid dispensing device 10.

[0063] In an exemplary embodiment, please combine Figure 5 , Figure 7 , Fig.15 , Fig.18 , Fig. 20 , Fig.24 and Fig. 27The transmission member 123 includes a plurality of moving parts 1231, and the inner core 1212 is provided with a plurality of sliding grooves 400 extending along the first direction.

At least one moving part 1231 is exposed from the inner core 1212 and is connected to the movable assembly 112. The transmission member 123 can slide relative to the inner core 1212 through the plurality of moving parts 1231, so as to transmit the driving force of the driving member 122 to the movable assembly 112, so as to rotate the movable assembly 112. In this way, the moving accuracy of the transmission member 123 can be improved through the plurality of moving parts 1231, thereby ensuring the transmission stability between the driving member 122 and the movable assembly 112.

[0064] The multiple moving parts 1231 are correspondingly accommodated in the multiple sliding grooves 400, which can increase the connection area between the moving parts 1231 and the inner core 1212 and play a limiting role, thereby preventing the transmission member 123 from moving away from the first direction and further improving the movement accuracy of the transmission member 123.

[0065] The plurality of moving parts 1231 are accommodated in the plurality of sliding grooves 400 in a one-to-one correspondence, and the transmission member 123 can be partially embedded in the inner core 1212. After being assembled with the inner core 1212, the transmission member 123 can be installed on the outer shell 1211 together with the inner core 1212, and then installed on the main body component 111, or the transmission member 123 can be installed on the main body component 111 together with the inner core 1212, and then installed on the outer shell 1211, so as to facilitate the installation of the transmission member 123. In addition, the outer shell 1211 and the inner core 1212 can restrict the transmission member 123 from both sides, and improve the connection stability between the transmission member 123 and the connecting member 121.

The provision of the limit bar 12121 can reduce the risk of the moving part 1231 escaping from the sliding groove 400, and can improve the connection stability of the transmission member 123 and the inner core 1212 before the transmission member 123 and the inner core 1212 are not installed in the housing 1211.

[0067] In an exemplary embodiment, please combine Figure 5 , Figure 7 , Fig.15 and Fig. 20, a first guide portion 500 is provided on the movable portion 1231. The inner core 1212 is provided with a second guide portion 12122, and is located in the sliding groove 400. The first guide portion 500 and the second guide portion 12122 both extend along the first direction, and one of the first guide portion 500 and the second guide portion 12122 can be accommodated in the other. In this way, by providing the first guide portion 500 and the second guide portion 12122, the connection area between the movable portion 1231 and the inner core 1212 can be further increased, the connection stability and the movement accuracy can be improved, and the movable portion 1231 can be further restricted from moving relative to the inner core 1212 in a direction that is angled with the first direction, thereby ensuring the transmission accuracy between the transmission member 123 and the movable component 112. In the disclosed embodiment, the first guide portion 500 is a groove structure. The second guide portion 12122 is a protruding structure.

[0068] In an exemplary embodiment, please combine Figure 5 , Figure 7 , Fig. 9 , Fig.13 , Fig.15 and Fig.16 , a first limiting portion 12111 is provided on the housing 1211, and a second limiting portion 11114 is provided on the body component 111 to limit the first limiting portion 12111. In this way, the limiting cooperation of the first limiting portion 12111 and the second limiting portion 11114 can prevent the housing 1211 from rotating relative to the body component 111, so as to ensure the matching accuracy between the driving member 122, the transmission member 123 and the movable component 112. One of the first limiting portion 12111 and the second limiting portion 11114 has a protruding structure, and the other has a groove structure. In the embodiment of the present disclosure, the first limiting portion 12111 has a protruding structure. The second limiting portion 11114 has a groove structure.

One of the third limiting portion 11115 and the fourth limiting portion 12123 has a protruding structure, and the other has a groove structure. In the embodiment of the present disclosure, the third limiting portion 11115 is provided on the body assembly 111 and has a protruding structure. The fourth limiting portion 12123 has a groove structure.

[0069] In an exemplary embodiment, please combine Figure 5 , Figure 7 , Fig.13 , Fig. 20 , Fig.23 and Fig.26 The transmission member 123 further includes a connecting plate 1232, and a plurality of moving parts 1231 are arranged on the connecting plate 1232. The arrangement of the connecting plate 1232 can ensure the synchronization of the movement of the plurality of moving parts 1231 relative to the inner core 1212. The outer shell 1211 is provided with a plurality of limiting protrusions 12112, and the plurality of limiting protrusions 12112 are arranged on the circumferential outer side of the transmission member 123, which can limit the position of the transmission member 123 relative to the outer shell 1211, so that the transmission member 123 and the inner core 1212 can be quickly installed on the outer shell 1211. Some of the plurality of limiting protrusions 12112 are arranged at both ends of the moving path of the transmission member 123, so that the moving range of the transmission member 123 can be limited, so as to ensure that within the above-defined moving range, the transmission member 123 and the movable component 112 are always in transmission connection, thereby ensuring the stability of the transmission. In the embodiment of the present disclosure, in order to make the assembly more compact, the aforementioned limit strip 12121 can cooperate with one of the limit protrusions 12112 to limit one end of the above-mentioned moving range, such as Fig.23 Another part of the plurality of limiting protrusions 12112 is configured to limit the transmission member 123 from moving in a direction deviating from the moving path, and can limit the transmission member 123 together with the first guide portion 500 and the second guide portion 12122 mentioned above to prevent the transmission member 123 from moving in a direction deviating from the first direction. In addition, in the embodiment of the present disclosure, the limiting protrusions 12112 can also abut the inner core 1212 against the body assembly 111 to prevent the inner core 1212 from moving axially.

[0070] In an exemplary embodiment, please combine Figure 4 , Figure 5 , Figure 7 , Fig.12 , Figure 7 , Fig. 20 , Fig.23 and Fig.26 The driving member 122 has a first driving part 1221, and the connecting plate 1232 has a second driving part 12321. One of the first driving part 1221 and the second driving part 12321 is a protrusion, and the other has a groove wall that encloses and forms a groove 600. The protrusion can be received in the groove 600 and cooperate with the groove wall in transmission. In this way, the groove wall can limit the protrusion to prevent the driving member 122 from separating from the transmission member 123 during the movement, and further improve the transmission stability between the driving member 122 and the transmission member 123. At the same time, the groove 600 can avoid the protrusion to avoid interference with the movement of the first driving part 1221 and the second driving part 12321, and avoid the occurrence of jamming.

[0071] The side of the projection that matches the groove wall in transmission is an arc surface, so that the projection and the groove wall are matched in a line-surface manner, which can reduce the contact area between the projection and the groove wall, thereby making the transmission smoother and further avoiding the occurrence of jamming. In the embodiment of the present disclosure, the projection is cylindrical.

[0072] In an exemplary embodiment, please combine Figure 5 , Figure 7 , Fig.18 , Fig.24 and Fig. 27 The transmission member 123 further includes a rack 1233, at least one moving part 1231 is exposed outside the inner core 1212 and connected to the rack 1233, and the operating mechanism 12 further includes a gear member 124 having a gear surface 1241, and the gear member 124 is detachably connected to the movable component 112 and can be engaged with each other to prevent rotation. The gear surface 1241 meshes with the rack 1233 to connect the movable component 112 with the transmission member 123. In this way, the stable transmission of the driving force can be achieved through the cooperation of the rack 1233 and the gear surface 1241, and then the driving force can be transmitted to the movable component 112 through the gear surface 1241 to drive the movable component 112 to rotate. The driving member 122 moves relative to the outer shell 1211 to drive the transmission member 123, so that the transmission member 123 can slide relative to the inner core 1212 through multiple moving parts 1231, so that the rack 1233 can drive the gear surface 1241 to roll relative to the rack 1233, so as to convert the linear motion of the transmission member 123 into the rotational motion of the gear surface 1241, thereby driving the movable component 112 to rotate, thereby realizing labor-saving and convenient liquid circuit switching.

[0073] In an exemplary embodiment, please combine Figure 3 , Figure 5 , Figure 7 , Fig.15 and Fig. 20 The inner core 1212 is provided with a through groove 700, and the gear member 124 is partially received in the through groove 700 and is rotatably connected to the inner core 1212. In this way, the setting of the through groove 700 can facilitate the rotation of the gear member 124 relative to the inner core 1212, thereby improving the rotation stability of the gear member 124.

[0074] The connecting plate 1232 at least partially blocks the side of the through slot 700 facing the connecting plate 1232 , and cooperates with the main body assembly 111 to clamp the gear part 124 along the axial direction of the gear part 124 to limit the axial movement of the gear part 124 and ensure the transmission stability between the gear part 124 and the transmission part 123 .

[0075] In an exemplary embodiment, please combine Figure 5 , Figure 7 , Fig.16 and Fig. 20The liquid separation device 10 further includes a positioning component 13. The positioning component 13 is disposed on the body component 111, and the gear member 124 is provided with a positioning plate 1242. The positioning plate 1242 is provided with a plurality of positioning grooves 800, and the plurality of positioning grooves 800 are configured to cooperate with the positioning component 13 for positioning in different connection and disconnection states of the liquid inlet flow channel 100 and the plurality of liquid outlet flow channels 200.

[0076] In the embodiment of the present disclosure, three positioning grooves 800 corresponding to the first position, the second position and the third position are provided on the positioning plate 1242, so as to cooperate with the positioning component 13 when the movable component 112 rotates to the first position, the second position and the third position to realize position feedback to prompt the rotation position of the movable component 112.

[0077] In an exemplary embodiment, please continue to refer to Figure 5 , Figure 7 , Fig.16 and Fig. 20 The positioning component 13 includes an abutment structure 131 and an elastic structure 132. The main body assembly 111 is provided with a first installation space 900. The abutment structure 131 is partially located in the first installation space 900 and can be slidably connected with the positioning plate 1242. The elastic structure 132 is installed in the first installation space 900 and can abut the abutment structure 131 against the positioning plate 1242. In this way, the setting of the elastic structure 132 can make the cooperation between the abutment structure 131 and the positioning plate 1242 tighter, avoiding the existence of a gap between the abutment structure 131 and the positioning plate 1242, resulting in abnormal noise when the abutment structure 131 slides relative to the positioning plate 1242. In addition, the elastic structure 132 can also make the abutment structure 131 relatively stably in the positioning groove 800, thereby improving the accuracy of position feedback. The elastic structure 132 can be, but is not limited to, a metal spring member and a plastic spring.

[0078] The elastic structure 132 is installed in the first installation space 900, so that the elastic structure 132 has a certain directionality in its expansion and contraction. The abutment structure 131 is a columnar structure with a spherical cap, and the abutment structure 131 is partially located in the first installation space 900, which can improve the movement accuracy under the limitation of the body assembly 111. The setting of the spherical cap can make the abutment structure 131 slide more smoothly relative to the positioning plate 1242, avoiding the occurrence of jamming.

[0079] In an exemplary embodiment, please combine Figure 7 and Fig. 20The inner core 1212 is also provided with an abutment portion 12124, which abuts against the side of the positioning plate 1242 away from the positioning component 13. In this way, the abutment portion 12124 can provide support for the positioning plate 1242, improve the structural strength of the positioning plate 1242, and further improve the matching accuracy between the positioning plate 1242 and the positioning component 13. In the embodiment of the present disclosure, the abutment portion 12124 is continuously or intermittently distributed along the rotation trajectory of the positioning plate 1242, and can always provide support for the positioning plate 1242 during the rotation of the positioning plate 1242 to ensure its structural strength.

[0080] In an exemplary embodiment, Figure 7 As shown, the inner core 1212 is provided with a limiting groove 1000, the abutment portion 12124 is accommodated in the limiting groove 1000, and the positioning plate 1242 is at least partially accommodated in the limiting groove 1000. In this way, through the setting of the limiting groove 1000, a limiting fit can be formed between the positioning plate 1242 and the inner core 1212, so as to limit the rotation range of the positioning plate 1242, thereby ensuring that the positioning plate 1242 is always stopped on the moving path of the abutment structure 131.

[0081] In an exemplary embodiment, please combine Figure 2 , Figure 3 , Figure 6 , Figure 8 , Fig.14 , Fig.17 , Fig.19 , Fig. 20 , Fig.23 and Fig.26 , the driving member 122 can swing relative to the housing 1211, so as to drive the movable component 112 to rotate relative to the main body component 111 through the transmission member 123. In this way, a structure capable of swinging relative to the housing 1211 is formed by the driving member 122, and a labor-saving lever structure can be formed in cooperation with the housing 1211 to facilitate driving the transmission member 123, so as to realize the rotation of the movable component 112 relative to the main body component 111. The above-mentioned lever structure can also make up for the torque of the gear pair formed by the rack 1233 and the gear surface 1241, and the problem of insufficient switching force caused by the inability to increase the torque due to the shape limitation of the liquid separation device 10. The liquid circuit is switched by swinging, the swinging motion of the driving member 122 is converted into the linear motion of the transmission member 123, and then the linear motion of the transmission member 123 is converted into the rotational motion of the movable component 112, so as to realize labor-saving and convenient liquid circuit switching.

[0082] One of the housing 1211 and the driving member 122 is provided with a rotating shaft 12113, and the other of the housing 1211 and the driving member 122 can be rotatably connected to the rotating shaft 12113, so that the driving member 122 can swing relative to the housing 1211. In this way, the setting of the rotating shaft 12113 can improve the stability of the swing of the driving member 122 relative to the housing 1211, and the lever fulcrum structure formed at the position of the rotating shaft 12113 is more stable, thereby improving the stability of driving the transmission member 123. In the embodiment of the present disclosure, the rotating shaft 12113 is provided on the housing 1211, and the driving member 122 is rotatably connected to the rotating shaft 12113.

[0083] The other of the housing 1211 and the driving member 122 can be detachably connected to the rotating shaft 12113 to facilitate the updating, upgrading or replacement of the driving member 122. In the embodiment of the present disclosure, the driving member 122 is provided with a card interface portion 1100 to facilitate the card connection and separation with the rotating shaft 12113.

[0084] In an exemplary embodiment, please combine Figure 3 , Figure 4 , Figure 6 , Fig.17 , Fig. 20 , Fig.23 and Fig.26 The liquid dispensing device 10 further includes a pin 14. The other of the housing 1211 and the driving member 122 is also connected to the rotating shaft 12113 via the pin 14. Thus, the connection stability between the housing 1211 and the driving member 122 can be further improved by the provision of the pin 14, and the housing 1211 and the driving member 122 can be stably connected while increasing the driving force of the driving member 122.

[0085] like Fig.13 and Fig. 20 As shown, an escape space 1200 is provided on the housing 1211 , and the escape space 1200 is configured to have an installation space for the pin shaft 14 , so that the disassembly and assembly of the pin shaft 14 can be facilitated, thereby facilitating the updating, upgrading, transformation or replacement of the driving member 122 .

The rotating member 1121 is rotatably connected to the main body component 111. The sealing member 1122 is arranged on the rotating member 1121. The transmission member 123 can drive the rotating member 1121 to rotate relative to the main body component 111, so that the sealing member 1122 slides relative to the main body component 111. In this way, when the rotating member 1121 moves relative to the main body component 111, the sealing member 1122 can slide relative to the main body component 111, while maintaining the fit between the sealing member 1122 and the main body component 111. In the embodiment of the present disclosure, the sealing member 1122 fits with the liquid separator 1112 and can slide relative to the liquid separator 1112 when the rotating member 1121 rotates relative to the main body component 111. The rotating member 1121 is disposed through the liquid separator 1112 and is connected to the gear member 124 to prevent rotation. The other end of the rotating member 1121 is connected to the sealing member 1122 so that the sealing member 1122 is in contact with the side of the liquid separator 1112 facing away from the gear member 124 .

[0088] like Figures 17 to 22 As shown, in the first position, the sealing member 1122 seals a portion of the first liquid outlet hole 2011 and a portion of the second liquid outlet hole 2021, so that the liquid inlet channel 100 can be connected to the first liquid outlet channel 201 and the second liquid outlet channel 202 respectively, thereby enabling the first liquid outlet channel 201 and the second liquid outlet channel 202 to discharge liquid at the same time.

[0091] In addition, in some exemplary embodiments, the seal 1122 can also seal the first liquid outlet hole 2011 and the second liquid outlet hole 2021 at the same time, so that the liquid inlet channel 100 can be disconnected from both the first liquid outlet channel 201 and the second liquid outlet channel 202, thereby preventing the first liquid outlet channel 201 and the second liquid outlet channel 202 from discharging liquid at the same time.

[0092] It can be understood that in other embodiments, the rotation trajectory of the movable component 112 relative to the main component 111 may also include other positions to switch other fluid circuits.

The flexible portion 11221 can better fit the main body component 111 through its own deformation, thereby ensuring a tight fit between the seal 1122 and the main body component 111.

[0094] The elastic part 11222 is supported between the rotating member 1121 and the flexible part 11221 to further enhance the elastic contact force of the flexible part 11221 on the body component 111, thereby further ensuring the close fit between the sealing member 1122 and the body component 111, ensuring the reliability of the subsequent sealing of the first liquid outlet channel 201 or the second liquid outlet channel 202, and ensuring the stability of the liquid path switching. The flexible part 11221 can be made of, but not limited to, an elastomer material. The elastic part 11222 can be, but not limited to, a metal spring member and a plastic spring.

[0097] In an exemplary embodiment, Fig.21 As shown, a receiving groove 1400 is provided on one side of the flexible portion 11221 away from the main body assembly 111, and the elastic portion 11222 is partially received in the receiving groove 1400 to improve the stability of the elastic deformation of the elastic portion 11222. In the embodiment of the present disclosure, the receiving groove 1400 is a tapered hole.

[0098] The flexible portion 11221 is provided with an arc-shaped protrusion 11223, which abuts against the hole wall of the second installation space 1300. In this way, under the action of the flexible portion 11221, the arc-shaped protrusion 11223 can fit closely with the hole wall, ensuring that the flexible portion 11221 is more stably installed in the second installation space 1300.
