The liquid dispensing mechanism 11 is further provided with a fixation structure 70, which may be detachably connected with the shower head 20.
In summary, an implementation of embodiments of the present disclosure will have the following beneficial effects: the liquid dispensing device 10 of the above-mentioned solution is applied to and installed in the liquid discharge system, and in addition to realizing the effect of switching liquid discharge of different liquid discharge elements of the liquid discharge system, the liquid dispensing device 10 itself may further improve the versatility of the liquid dispensing device 10. Specifically, the liquid dispensing device 10 includes a liquid dispensing mechanism 11 and an operation mechanism 12. The liquid dispensing mechanism 11 includes a main body assembly 111 provided with a liquid intake channel 100 and multiple liquid discharge channels 1400, and a movable assembly 112 movably installed to the main body assembly 111. The operation mechanism 12 is capable of driving the movable assembly 112 to rotate relative to the main body assembly 111, so as to discommunicate at least one of the multiple liquid discharge channels 1400 from the liquid intake channel 100, or to communicate the multiple liquid discharge channels 1400 with the liquid intake channel 100. In this way, by rotating the movable assembly 112 relative to the main body assembly 111, the communication state between the liquid intake channel 100 and the multiple liquid discharge channels 1400 may be changed, and different liquid discharge channels 1400 may be switched to discharge liquid or all the liquid discharge channels 1400 may be closed simultaneously according to specific usage requirements. The operation mechanism 12 is detachably connected to the liquid dispensing mechanism 11, so that when the operation mechanism 12 or the liquid dispensing mechanism 11 is updated and upgraded, it is not necessary to make a mold for the whole liquid dispensing device 10, thereby reducing the production cost caused by updating and upgrading. When the user wishes to upgrade and change an operation mode or a liquid dispensing mode and an operation structure or a liquid dispensing structure is damaged and needs to be replaced, the liquid dispensing device 10 does not need to be purchased as a whole, thereby reducing a cost of upgrading, changing and replacing the liquid dispensing device 10.
In an exemplary embodiment, referring to FIGS. 2 to 6 together, the operation mechanism 12 includes a rotary element 121. The rotary element 121 is detachably connected to the movable assembly 112. In this way, when the operation mechanism 12 or the liquid dispensing mechanism 11 is updated and upgraded, and when the user wishes to upgrade and change the operation mode or the liquid dispensing mode, and the operation structure or the liquid dispensing structure is damaged and needs to be replaced, the rotary element 121 may be separated from the movable assembly 112, so that the separation between the operation mechanism 12 and the liquid dispensing mechanism 11 is realized, and one of the operation mechanism 12 and the liquid dispensing mechanism 11 is replaced while the other of the operation mechanism 12 and the liquid dispensing mechanism 11 is retained, so that a portion of the liquid dispensing device 10 is universal, which is cost effective. The rotary element 121 is capable of driving the movable assembly 112 to rotate relative to the main body assembly 111, so as to discommunicate at least one of the multiple liquid discharge channels 1400 from the liquid intake channel 100, or to communicate the multiple liquid discharge channels 1400 with the liquid intake channel 100.
In an exemplary embodiment, referring to FIGS. 2 to 4 and 6 together, one of the rotary element 121 and the main body assembly 111 is provided with a protrusion 1211, and the other of the rotary element 121 and the main body assembly 111 is provided with a clamping groove 500. The rotary element 121 may be clamped with the main body assembly 111 by a cooperation between the protrusion 1211 and the clamping groove 500, and may rotate relative to the main body assembly 111 so as to drive the movable assembly 112 to rotate relative to the main body assembly 111. In this way, a fast assembly of the rotary element 121 and the main body assembly 111 may be realized by the cooperation between the protrusion 1211 and the clamping groove 500. At the same time, by the cooperation between the protrusion 1211 and the clamping groove 500, the rotary element 121 may also rotate relative to the main body assembly 111, and the rotation stability of the rotary element 121 is improved, thereby improving the stability of driving the movable assembly 112. In addition, the rotary element 121 may increase a connection area between the rotary element 121 and the main body assembly 111 by the cooperation between the protrusion 1211 and the clamping groove 500 to improve the connection stability.
At least one of the rotary element 121 and the main body assembly 111 may also be elastically deformed to move the protrusion 1211 out of the clamping groove 500. This enables a detachable connection between the rotary element 121 and the main body assembly 111.
In an embodiment of the present disclosure, the protrusion 1211 is provided on the rotary element 121, and the clamping groove 500 is provided on the liquid dispensing element 1112, and the clamping groove 500 may extend in a circumferential direction of the liquid dispensing element 1112 to facilitate the rotation of the rotary element 121. An extension distance of the clamping groove 500 may be designed to define a rotation range of the rotary element 121. In addition, in some embodiments, the clamping groove 500 may also be provided on the housing 1111 and cooperated with the protrusion 1211 provided on the rotary element 121. It may be understood that in other embodiments, the clamping groove 500 may also be provided on the rotary element 121, and correspondingly, the protrusion 1211 is provided on the liquid dispensing element 1112 or the housing 1111.
In an exemplary embodiment, referring to FIGS. 3, 4, and 6 together, the operation mechanism 12 further includes a first positioning assembly 1214.

It can be understood that in other embodiments, the rotation trajectory of the movable assembly 112 rotating relative to the main body assembly 111 may further include other positions for the switching of other liquid paths.
In an exemplary embodiment, referring to FIGS. 6, 26, 27, 30 and 31 together, the scaling element 1122 includes a flexible part 11221 and an elastic part 11222. The flexible part 11221 may be elastically abutted against the main body assembly 111 and the flexible part 11221 may be better fitted against the main body assembly 111 by deforming itself to ensure a tighter fit between the sealing element 1122 and the main body assembly 111. The elastic part 11222 is supported between the rotation element 1121 and the flexible part 11221 to further enhance an elastic abutment force of the flexible part 11221 acting on the main body assembly 111, thereby further ensuring a tighter fit between the sealing element 1122 and the main body assembly 111, ensuring a reliability of a subsequent closing of the first liquid discharge channel 200 or the second liquid discharge channel 300, and ensuring the stability of the liquid path switching. The flexible part 11221 may be made of, but is not limited to, an elastomer material. The elastic part 11222 may be made of, but is not limited to, a metal spring element and a plastic spring.
In an exemplary embodiment, as shown in FIGS. 6, 27, and 31, a second installation space 11210 is provided on the rotation element 1121, and the elastic part 11222 is installed in the second installation space 11210, so that the extension and retraction of the elastic part 11222 has a certain directionality. The flexible part 11221 is partially accommodated in the second installation space 11210. In this way, a connection area between the flexible part 11221 and the rotation element 1121 is increased, and the connection stability between the flexible part 11221 and the rotation element 1121 is increased.
In an exemplary embodiment, as shown in FIGS. 6, 27, and 31, an accommodation groove 600 is provided on a side of the flexible part 11221 facing away from the main body assembly 111, and an elastic part 11222 is partially accommodated in the accommodation groove 600, so that the flexible part 11221 may be abutted against the hole wall 112101 of the second installation space 11210, and the connection stability between the flexible part 11221 and the rotation element 1121 may be further improved. In an embodiment of the present disclosure, the accommodation groove 600 is a tapered hole, and the elastic part 11222 is partially accommodated in the accommodation groove 600 and expands the flexible part 11221 toward the hole wall 112101, thereby further improving the connection stability between the flexible part 11221 and the rotation element 1121.
In an exemplary embodiment, as shown in FIGS. 6, 27, and 31, the flexible part 11221 is provided with an arc-shaped protrusion 112211 and the arc-shaped protrusion 112211 abuts against the hole wall 112101. In this way, under an action of the flexible part 11221 and the elastic part 11222, the arc-shaped protrusion 112211 may be more closely fitted against the hole wall 112101, and the flexible part 11221 may be more stably installed in the second installation space 11210.

The liquid dispensing mechanism 11 is further provided with a fixation structure 70, which may be detachably connected with the shower head 20.
In summary, the implementation of embodiments of the present disclosure has the following beneficial effects: the liquid dispensing device 10 of the above-mentioned solution is applied to and installed in the liquid discharge system, and in addition to realizing the effect of switching liquid discharge of different liquid discharge elements of the liquid discharge system, it can also facilitate the installation of the transmission element 124 and improve the assembly efficiency. Specifically, the liquid dispensing device 10 includes a liquid dispensing mechanism 11 and an operation mechanism 12. The liquid dispensing mechanism 11 includes a main body assembly 111 provided with a liquid intake channel 100 and multiple liquid discharge channels 1400, and a movable assembly 112 movably installed to the main body assembly 111. The operation mechanism 12 includes a connection element 122, a driving element 123, and a transmission element 124. The connection element 122 includes an outer housing 1225 and an inner core 1226 that are detachably connected, and the transmission element 124 is movably installed between the outer housing 1225 and the inner core 1226, so that the installation of the transmission element 124 is convenient and the assembly efficiency is improved. Moreover, the outer housing 1225 and the inner core 1226 may restrict the transmission element 124 from two sides, thus improving the connection stability between the transmission element 124 and the connection element 122, and ensuring the transmission stability of the transmission element 124. The driving element 123 is capable of driving the movable assembly 112 to rotate relative to the main body assembly 111 through the transmission element 124, so as to discommunicate at least one of the multiple liquid discharge channels 1400 from the liquid intake channel 100, or to communicate the multiple liquid discharge channels 1400 with the liquid intake channel 100. In this way, by rotating the movable assembly 112 relative to the main body assembly 111, the communication state between the liquid intake channel 100 and the multiple liquid discharge channels 1400 may be changed, and different liquid discharge channels 1400 may be switched to discharge liquid or all the liquid discharge channels 1400 may be closed simultaneously according to specific usage requirements.
The outer housing 1225 is detachably connected to the main body assembly 111 to facilitate the disassembly and connection of the operation mechanism 12 and the liquid dispensing mechanism 11. After installation, the inner core 1226 and the transmission element 124 may be detachably connected to the main body assembly 111 together with the driving element 123 and the outer housing 1225. After installation, the inner core 1226 and the transmission element 124 may also be detachably connected to the main body assembly 111 first, and then detachably connected to the driving element 123 and the outer housing 1225 together with the main body assembly 111. In this way, when the operation mechanism 12 or the liquid dispensing mechanism 11 is updated and upgraded, it is not necessary to make a mold for the whole liquid separating device 10, thereby reducing the production cost caused by updating and upgrading. When the user wishes to upgrade and change an operation mode or a liquid dispensing mode and an operation structure or a liquid dispensing structure is damaged and needs to be replaced, the liquid dispensing device 10 does not need to be purchased as a whole, thereby reducing a cost of upgrading, changing and replacing the liquid dispensing device 10.

At least one movement part 1244 is exposed to the inner core 1226 and is in transmission connection with the movable assembly 112. The transmission element 124 is capable of sliding relative to the inner core 1226 through the multiple movement parts 1244, so as to be able to transmit the driving force of the driving element 123 to the movable assembly 112 to rotate the movable assembly 112.

The fourth limiting part 12263 may cooperate with the third limiting part 11114 to prevent the inner core 1226 from rotating relative to the outer housing 1225 and the main body assembly 111, thereby ensuring a stable position of the inner core 1226, and further ensuring the transmission stability of the transmission element 124. One of the third limiting part 11114 and the fourth limiting part 12263 has a protrusion structure, and the other of the third limiting part 11114 and the fourth limiting part 12263 has a groove structure.

The outer housing 1225 is provided with multiple limiting protrusions 12251, and the multiple limiting protrusions 12251 are provided on the circumferential outer side of the transmission element 124, which can limit the position of the transmission element 124 relative to the outer housing 1225, and facilitate a rapid installation of the transmission element 124 and the inner core 1226 to the outer housing 1225. A portion of the multiple limiting protrusions 12251 are provided at two ends of the movement path of the transmission element 124, so that a movement range of the transmission element 124 may be restricted, and within the above-mentioned limited movement range, the transmission element 124 is always in transmission connection with the movable assembly 112, and the transmission stability is guaranteed. In an embodiment of the present disclosure, in order to make the assembly more compact, the previously mentioned limiting strip 12261 may cooperate with one of the limiting protrusions 12251 to limit one end of the above-mentioned movement range, as shown in FIG. 61.

The protrusion may be accommodated in the groove and is in transmission cooperation with the groove wall 12431. In this way, the groove wall 12431 may limit the protrusion to prevent the driving element 123 from being separated from the transmission element 124 during movement process, further improving the transmission stability between the driving element 123 and the transmission element 124. Meanwhile, the groove may avoid the protrusion, thereby avoiding interference on the motion of the first driving part 1232 and the second driving part 1243, and avoiding an occurrence of a jamming phenomenon.
A side of the first driving part 1232 that is in transmission cooperation with the groove wall 12431 is an arc-shaped surface 12321, so that there is a line-surface mating between the first driving part 1232 and the groove wall 12431, and a contact area between the first driving part 1232 and the groove wall 12431 may be reduced, thereby making the transmission smoother and further avoiding an occurrence of a jamming phenomenon.

The gear face engages with the rack 1242 to make the movable assembly 112 in transmission connection with the transmission element 124. In this way, the stable transmission of the driving force may be achieved by the cooperation between the rack 1242 and the gear face, and the driving force may be transmitted to the movable assembly 112 through the gear face, so as to drive the movable assembly 112 to rotate. The driving element 123 moves relative to the outer housing 1225 to drive the transmission element 124, so that the transmission element 124 may slide relative to the inner core 1226 through multiple movement parts 1244, and the rack 1242 may drive the gear face to roll relative to the rack 1242, so as to convert a linear motion of the transmission element 124 into a rotational motion of the gear face, thereby driving the rotational motion of the movable assembly 112, and a labor-saving and convenient liquid path switching is achieved.

In an embodiment of the present disclosure, three positioning grooves 1100 corresponding to the first position, the second position and the third position are provided on the positioning plate 1251 to cooperate with the positioning component 13 when the movable assembly 112 rotates to the first position, the second position, and the third position, thus realizing a position feedback to prompt the rotation position of the movable assembly 112.
In an exemplary embodiment, continuously referring to FIGS. 43, 45, 54 and 58, 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 12610, the abutment structure 131 is partially located in the first installation space 12610 and capable of slidably connecting with the positioning plate 1251. The elastic structure 132 is installed in the first installation space 12610 and capable of abutting the abutment structure 131 against the positioning plate 1251. In this way, a cooperation between the abutment structure 131 and the positioning plate 1251 may be tighter by an arrangement of the elastic structure 132, and a gap between the abutment structure 131 and the positioning plate 1251 may be avoided, which results in abnormal noise generated when the abutment structure 131 slides relative to the positioning plate 1251. In addition, the elastic structure 132 may further enable the abutment structure 131 to be relatively stable in the positioning groove 1100, so as to improve the accuracy of the position feedback. The elastic structure 132 may be, but is not limited to, a metal spring element and a plastic spring.
The elastic structure 132 is installed in the first installation space 12610, so that an extension and retraction of the elastic structure 132 has a certain directionality. The abutment structure 131 has a columnar structure and a spherical crown. The abutment structure 131 is partially located in the first installation space 12610, and may improve a movement accuracy under a restriction of the main body assembly 111. An arrangement of the spherical crown enables the abutment structure 131 to slide more smoothly relative to the positioning plate 1251, and avoids an occurrence of a jamming phenomenon.
In an exemplary embodiment, referring to FIGS. 45 and 58 together, the inner core 1226 is further provided with an abutment part 1222, and the abutment part 1222 abuts against a side of the positioning plate 1251 facing away from the positioning component 13. In this way, an arrangement of the abutment part 1222 may provide support for the positioning plate 1251, improve the structural strength of the positioning plate 1251, and further improve the cooperation accuracy between the positioning plate 1251 and the positioning component 13. In an embodiment of the present disclosure, the abutment part 1222 is continuously or intermittently distributed along the rotation trajectory of the positioning plate 1251, and may always provide support for the positioning plate 1251 during the rotation process of the positioning plate 1251, so as to ensure the structural strength of the positioning plate 1251.
In an exemplary embodiment, as shown in FIG. 45, the inner core 1226 is provided with a limiting groove 1200. The abutment part 1222 is accommodated in the limiting groove 1200, and the positioning plate 1251 is at least partially accommodated in the limiting groove 1200, so that a limiting cooperation may be formed between the positioning plate 1251 and the inner core 1226 by an arrangement of the limiting groove 1200, a rotation range of the positioning plate 1251 may be restricted, and the positioning plate 1251 is always located in the movement path of the abutment structure 131.
In an exemplary embodiment, referring to FIGS. 40, 41, 44, 46, 52, 55, 57, 58, 61, and 64 together, the driving element 123 may be swung relative to the outer housing 1225, so as to drive the movable assembly 112 to rotate relative to the main body assembly 111 by the transmission element 124. In this way, the driving element 123 forms a structure that may be swung relative to the outer housing 1225, and may cooperate with the outer housing 1225 to form a labor-saving lever structure, so that the transmission element 124 is convenient to be driven, and the movable assembly 112 may rotate relative to the main body assembly 111. The above-mentioned lever structure may also compensate for a problem that a torque of a gear pair formed by the rack 1242 and the gear face cannot increase insufficient switching force under the limiting of the shape of the liquid dispensing device 10. The liquid path is switched by a swinging mode, and a swinging motion of the driving element 123 is converted into a linear motion of the transmission element 124, and then the linear motion of the transmission element 124 is converted into a rotational motion of the movable assembly 112, thereby realizing a labor-saving and convenient liquid path switching.
One of the outer housing 1225 and the driving element 123 is provided with a rotary shaft 1224, and the other of the outer housing 1225 and the driving element 123 may be rotatably connected to the rotary shaft 1224, so that the driving element 123 may be swung relative to the outer housing 1225. In this way, an arrangement of the rotary shaft 1224 may improve the stability of the swinging of the driving element 123 relative to the outer housing 1225, and a lever fulcrum structure formed at a position of the rotary shaft 1224 is more stable, thereby improving the stability of driving the transmission element 124. In an embodiment of the present disclosure, the rotary shaft 1224 is provided on the outer housing 1225, and the driving element 123 is rotatably connected to the rotary shaft 1224.
The other of the outer housing 1225 and the driving element 123 may be detachably connected to the rotary shaft 1224 to facilitate updating, upgrading, changing or replacement due to damage of the driving element 123. In an embodiment of the present disclosure, the driving element 123 is provided with a clamp opening part 1231 to facilitate clamping with and separating from the rotary shaft 1224.
In an exemplary embodiment, referring to FIGS. 41, 42, 44, 55, 58, 61 and 64 together, the liquid dispensing device 10 further includes a pin shaft 14. The other of the outer housing 1225 and the driving element 123 is further connected to the rotary shaft 1224 by the pin shaft 14. In this way, a connection stability between the outer housing 1225 and the driving element 123 may be further improved by an arrangement of the pin shaft 14, and a stable connection between the outer housing 1225 and the driving element 123 may be ensured while increasing the driving force of the driving element 123.
As shown in FIGS. 51 and 58, an avoidance space 1300 is provided on the connection element 122, and the avoidance space 1300 is provided with an installation space for the pin shaft 14, so as to facilitate the disassembly and assembly of the pin shaft 14, and to further facilitate updating, upgrading, changing or replacement due to damage of the driving element 123. In an embodiment of the present disclosure, the outer housing 1225 is provided with the avoidance space 1300.
In an exemplary embodiment, referring to FIGS. 47 to 49, 54, 59, 60, 63 and 66 together, the movable assembly 112 includes a rotation element 1121 and a sealing element 1122. The rotation element 1121 is rotatably connected to the main body assembly 111, and the sealing element 1122 is provided on the rotation element 1121. The transmission element 124 may drive the rotation element 1121 to rotate relative to the main body assembly 111 so that the sealing element 1122 slides relative to the main body assembly 111. In this way, when the rotation element 1121 moves relative to the main body assembly 111, the sealing element 1122 may slide relative to the main body assembly 111 while maintaining the fit between the sealing element 1122 and the main body assembly 111. In an embodiment of the present disclosure, the sealing element 1122 is fitted to the liquid dispensing element 1112 and may slide relative to the liquid dispensing element 1112 when the rotation element 1121 rotates relative to the main body assembly 111. The rotation element 1121 is inserted into the liquid dispensing element 1112 and irrotationally connected to the gear element 125, and the other end is connected to the sealing element 1122, so that the sealing element 1122 is fitted to a side of the liquid dispensing element 1112 facing away from the gear element 125.
During a rotation process of the rotation element 1121 relative to the main body assembly 111, the sealing element 1122 is capable of sealing at least one of the multiple liquid discharge channels 1400 to discommunicate at least one of the multiple liquid discharge channels 1400 from the liquid intake channel 100, or exposing the multiple liquid discharge channels 1400 on the main body assembly 111 to communicate the multiple liquid discharge channels 1400 with the liquid intake channel 100.
As shown in FIGS. 55 to 60, at a first position, the seal element 1122 seals a portion of the first liquid discharge hole 201 and a portion of the second liquid discharge hole 301 so that the liquid intake channel 100 may communicate with the first liquid discharge channel 200 and the second liquid discharge channel 300, respectively, and the first liquid discharge channel 200 and the second liquid discharge channel 300 may simultaneously discharge liquid.
As shown in FIGS. 61 to 63, at a second position, the sealing element 1122 seals the second liquid discharge hole 301 so that the liquid intake channel 100 communicates with the first liquid discharge channel 200, thereby enabling the first liquid discharge channel 200 to discharge liquid.
As shown in FIGS. 64 to 66, at a third position, the sealing element 1122 seals the first liquid discharge hole 201 so that the liquid intake channel 100 communicates with the second liquid discharge channel 300, thereby enabling the second liquid discharge channel 300 to discharge liquid.
In addition, in some exemplary embodiments, the sealing element 1122 may also seal the first liquid discharge hole 201 and the second liquid discharge hole 301 simultaneously, so that the liquid intake channel 100 may be discommunicated from both the first liquid discharge channel 200 and the second liquid discharge channel 300, and both the first liquid discharge channel 200 and the second liquid discharge channel 300 may simultaneously not discharge liquid.
It can be understood that in other embodiments, the rotation trajectory of the movable assembly 112 rotating relative to the main body assembly 111 may further include other positions for the switching of other liquid paths.
In an exemplary embodiment, referring to FIGS. 47, 49 and 59 together, the sealing element 1122 includes a flexible part 11221 and an elastic part 11222. The flexible part 11221 may be elastically abutted against the main body assembly 111 and the flexible part 11221 may be better fitted against the main body assembly 111 by deforming itself to ensure a tighter fit between the sealing element 1122 and the main body assembly 111.
The elastic part 11222 is supported between the rotation element 1121 and the flexible part 11221 to further enhance an elastic abutment force of the flexible part 11221 acting on the main body assembly 111, thereby further ensuring a tighter fit between the scaling element 1122 and the main body assembly 111, ensuring a reliability of a subsequent scaling of the first liquid discharge channel 200 or the second liquid discharge channel 300, and ensuring the stability of the liquid path switching. The flexible part 11221 may be made of, but is not limited to, an elastomer material. The elastic part 11222 may be, but is not limited to, a metal spring element and a plastic spring.
In an exemplary embodiment, referring to FIGS. 47 and 59 together, a second installation space 11210 is provided in the rotation element 1121, and the elastic part 11222 is installed in the second installation space 11210, so that the extension and retraction of the elastic part 11222 has a certain directionality.
The flexible part 11221 is partially accommodated in the second installation space 11210. In this way, a connection area between the flexible part 11221 and the rotation element 1121 may be increased, and a connection stability between the flexible part 11221 and the rotation element 1121 is increased.
In an exemplary embodiment, as shown in FIG. 59, an accommodation groove 600 is provided on a side of the flexible part 11221 facing away from the main body assembly 111, and the elastic part 11222 is partially accommodated in the accommodation groove 600, so as to improve the stability of the elastic deformation of the elastic part 11222. In an embodiment of the present disclosure, the accommodation groove 600 is a tapered hole.
The flexible part 11221 is provided with an arc-shaped protrusion 112211, and the arc-shaped protrusion 112211 abuts against the hole wall 112101 of the second installation space 11210. In this way, under an action of the flexible part 11221, the arc-shaped protrusion 112211 may be closely fitted against the hole wall 112101, and the flexible part 11221 may be more stably installed in the second installation space 11210.
