[0039] Embodiments of the present application provide a water outlet switching assembly, as in the example shown in FIGS. 1-17, the water outlet switching assembly comprising:

[0040] a valve body 3 having an internal cavity and a water inlet and a plurality of water outlets 311 communicating with the internal cavity;

[0041] a plurality of valve cores 5, each valve core 5 being installed in the internal cavity and corresponding to one water outlet 311, each valve core 5 being configured to be able to open and close the corresponding water outlet 311 by moving, wherein each valve core 5 is provided with a through shaft hole 501, and a protruding portion 502 is protrudingly provided on one side wall surface of the through shaft hole 501;

[0042] The rotating shaft 4 is arranged to pass through the shaft hole 501 of the plurality of valve cores 5 in sequence, and a plurality of pushing protrusions 403 are arranged on the outer circumferential surface of the rotating shaft 4 and are spaced in the axial direction and staggered in the circumferential direction, each pushing protrusion 403 corresponding to the protruding portion 502 of a valve core 5 in the axial direction;

[0043] The pushing mechanism includes a pushing component, and the pushing mechanism is arranged to be capable of driving the rotating shaft 4 to rotate by pushing the pushing component.

[0044] Wherein, each time the pushing component is pushed, the rotating shaft 4 rotates by a preset angle, and one of the pushing protrusions 403 pushes the corresponding protruding portion 502 to a predetermined position, so that the valve core 5 with the protruding portion 502 moves to open the corresponding water outlet 311.

[0045] Figures 8-11 show that the water outlet switching assembly in one embodiment is provided with four valve cores 5, namely a first valve core 5a, a second valve core 5b, a third valve core 5c and a fourth valve core 5d, which are respectively installed corresponding to a first water outlet 311a, a second water outlet 311b, a third water outlet 311c and a fourth water outlet 311d, and the rotating shaft 4 is provided with a first pushing protrusion 403a, a second pushing protrusion 403b, a third pushing protrusion 403c and a fourth pushing protrusion 403d for pushing the protruding portions 502 of the four valve cores 5 respectively, and each time the pushing component is pushed, one of the first pushing protrusion 403a, the second pushing protrusion 403b, the third pushing protrusion 403c and the fourth pushing protrusion 403d pushes the corresponding valve core 5 to open the water outlet 311 corresponding to the valve core.

[0046] The water outlet switching assembly provided by the embodiment of the present application adopts a pushing mode to drive the rotating shaft 4 to rotate, and the rotation of the rotating shaft 4 can push the valve core 5 to move to realize the switching of the water outlet, and the switching operation is simple and convenient, and the water outlet switching assembly is especially suitable for realizing the switching of three or more water outlets, and the structure is simple, can well meet the diversity of the selection of the function switching of consumers, improve the hand feeling and use experience of the function switching, and the structure is convenient to produce and process and low in cost, and has strong practicability.

[0047] In one embodiment of the present application, as shown in Figures 6 and 13, the opposite sides of the protruding portion 502 of the valve core 5 are respectively provided with a first inclined surface 5021 and a second inclined surface 5022, and the first inclined surface 5021 and the second inclined surface 5022 are inclined towards each other and extend to the top of the protruding portion 502.

[0048] When the rotating shaft 4 rotates to make one of the pushing protrusions 403 move along the first inclined surface 5021 to the top of the protruding part 502, the valve core 5 moves to the position to open the corresponding water outlet 311, and the valve core 5 keeps the corresponding water outlet 311 open during the process that the pushing protrusion 403 keeps on the top of the protruding part 502 until the pushing part is pushed again. When the rotating shaft 4 rotates to make the pushing protrusion 403 move along the second inclined surface 5022 from the top of the protruding part 502 to release the protruding part 502, the valve core 5 moves to the position to close the corresponding water outlet 311. During the process that the pushing part is pushed to rotate the rotating shaft 4, one of the pushing protrusions 403 moves along the second inclined surface 5022 to release the protruding part 502, and the other pushing protrusion 403 moves along the first inclined surface 5011 to the top of the protruding part 502, so that the water outlet switching assembly switches once for each pushing of the pushing part, i.e. switches to another water outlet 311.

[0049] When the pushing protrusion 403 is on the top of the protruding part 502, to make the pushing protrusion 403 keep on the top of the protruding part 502 stably, as shown in FIG. 12, a groove 4033 is formed on the top of the pushing protrusion 403, and the groove 4033 cooperates with the top of the protruding part 502 when the pushing protrusion 403 is on the top of the protruding part 502, so that the protruding part 502 cannot slide off the pushing protrusion 403.

[0050] In the examples shown in FIGS. 6 and 12, the two sides of the pushing protrusion 403 are respectively provided with a first arc surface 4031 and a second arc surface 4032. As shown in FIG. 6, during the rotation of the pushing protrusion 403, the first arc surface 4031 cooperates with the first inclined surface 5021 to slide, and the second arc surface 4032 cooperates with the second inclined surface 5022 to slide, so that the sliding is smooth and there is no problem of jamming.

[0051] In one embodiment, the multiple pushing protrusions 403 arranged along the axis of the rotating shaft 4 are each separated by the same angle in the circumferential direction. In this way, for each pushing of the pushing part, the pushing part drives the rotating shaft 4 to rotate by the same angle, and the pushing protrusion 403 pushes the valve core 5 to switch once. To make the user know how to complete one pushing, an elastic positioning part can be arranged on the pushing part, and multiple pits cooperating with the elastic positioning part are arranged on the mounting structure (such as the connecting pipe 2 or the mounting body 1) on which the pushing part is mounted. For each pushing of the pushing part, the elastic positioning part moves out of one pit and is positioned in another pit, thereby completing one pushing. During the process that the elastic positioning part moves out of one pit and is positioned in another pit, a sound is emitted, which is beneficial to improve the pushing experience of the user.

[0052] In one embodiment, as shown in FIG. 9 and FIG. 11, the pushing mechanism further comprises a gear wheel 401 connected to one end of the rotating shaft 4 and having a gear portion, and the pushing component comprises a rack structure 7 matched with the gear portion, and the pushing component is pushed to make the rack structure 7 engage with the gear portion, so that the gear wheel 401 drives the rotating shaft 4 to rotate.

[0053] In the example shown in FIG. 4-5, the pushing component comprises not only the rack structure 7, but also a pushing rod 8 connected with the rack structure 7 and a pushing handle 9 connected with the pushing rod 8. As shown in FIG. 4, the water outlet switching assembly further comprises the mounting body 1 and a connecting pipe 2 mounted on the mounting body 1, which is a water pipe for supplying water to the internal cavity of the valve body 3. The connecting pipe 2 can be provided with a sliding rail 201, the pushing rod 8 is slidably mounted on the sliding rail 201, and the pushing handle 9 passes through an elongated hole 101 provided on the mounting body 1 and is clamped and fixed to a clamping hole 801 provided on the pushing rod 8. In this way, the user pushes the pushing handle 9 forward or backward, the pushing handle 9 moves along the elongated hole 101 and drives the pushing rod 8 to push the rack structure 7 to move, and the rack structure 7 engages with the gear wheel 401 to drive the rotating shaft 4 to rotate.

[0054] It can be understood that the structure capable of driving the rotating shaft 4 to rotate is not limited to the meshing mode of the rack and the gear wheel, for example, the pushing component can comprise a nut, and the rotating shaft 4 can be a lead screw, and the lead screw can be driven to rotate by the meshing of the nut and the lead screw when the nut moves linearly.

[0055] In one embodiment, as shown in the example of FIG. 4 and FIG. 16-17, the valve body 3 comprises a valve body 31 and a valve cover 32, and the valve cover 32 and the valve body 31 cooperate to limit a plurality of valve cores 5 in the internal cavity. Among them, the valve cover 32 is provided with a water inlet pipe 321, and the water inlet pipe 321 is connected with the connecting pipe 2, and the water input by the connecting pipe 2 enters the internal cavity of the valve body 3 through the water inlet pipe 321.

[0056] In order to install the rotating shaft 4, the valve body 3 is provided with a first mounting hole 313 and a second mounting hole 314. Referring to FIG. 12 and FIG. 15, one end of the rotating shaft 4 is provided with a rotating mounting portion 402 which is mounted in cooperation with the first mounting hole 313, and the other end is provided with a rotating ring 10 which is mounted in cooperation with the second mounting hole 314. After the rotating shaft 4 passes through the first mounting hole 313 and the second mounting hole 314, the rotating ring 10 is mounted in the second mounting hole 314 and fixed to the rotating shaft 4. A C-shaped clasp ring 11 which is clamped on the rotating shaft 4 can be mounted on the outside of the rotating ring 10, and the rotating ring 10 is limited in the axial direction by the C-shaped clasp ring 11 to prevent the rotating ring 10 from being axially separated from the rotating shaft 4. Alternatively, the rotating ring 10 can be clamped on the rotating shaft 4. A third sealing ring 12 is arranged between the rotating mounting portion 402 and the hole wall of the first mounting hole 313, a fourth sealing ring 13 is arranged between the rotating ring 10 and the hole wall of the second mounting hole 314, and a fifth sealing ring 14 is arranged between the rotating ring 10 and the rotating shaft 4, so that the gap between the rotating shaft 4 and the valve body 3 is sealed. An annular groove 4021 for mounting the third sealing ring 12 can be arranged on the outer periphery of the rotating mounting portion 402, and an annular groove for mounting the fourth sealing ring 13 can be arranged on the outer periphery of the rotating ring 10.

[0057] According to the embodiment, the rotating mounting portion 402 is mounted in the first mounting hole 313 of the valve body 3, and the rotating ring 10 is mounted in the second mounting hole 314. When the rotating shaft 4 is rotated, the water in the valve body 3 is applied to the rotating mounting portion 402 and the rotating ring 10 in two axial directions. When the hole diameters of the first mounting hole 313 and the second mounting hole 314 are substantially the same, the water pressure of the water in the valve body 3 on the rotating shaft 4 in the two axial directions is substantially the same. Thus, the problem of the rotating shaft 4 being rubbed against the valve body 3 and being difficult to rotate due to the unbalanced water pressure in the two axial directions can be avoided.

[0058] In one embodiment, a reset spring 6 is arranged corresponding to each valve core 5. When the rotating shaft 4 is rotated to the point where the pushing protrusion 403 releases the pushed protrusion 502, the valve core 5 with the protrusion 502 is moved to close the corresponding water outlet 311 under the elastic force of the reset spring 6.

[0059] In the example shown in FIG. 8 and FIG. 10, the valve body 3 is provided with an end positioning hole 315 corresponding to each valve core 5, the valve core 5 has a first end and a second end in the moving direction, the first end of the valve core 5 is movably installed in the end positioning hole 315, so that the first end of the valve core 5 and the valve body 3 form a cavity A in the end positioning hole 315, wherein the first end of the valve core 5 and the hole wall of the end positioning hole 315 have a first sealing ring 504 to prevent water in the valve body 3 from entering the cavity A from the gap between the valve core 5 and the hole wall of the end positioning hole 315; wherein the return spring 6 is arranged to apply an elastic force to the valve core 5 from the first end to the second end, and the pushing protrusion 403 of the rotating shaft 4 is arranged to push the valve core 5 in the direction from the second end to the first end to open the corresponding water outlet 311. In this example, the return spring 6 is installed in the cavity A of the end positioning hole 315, and one end is abutted against the valve core 5 and the other end is abutted against the valve body 3, thereby applying an elastic force to the valve core 5 from the first end to the second end.

[0060] This example prevents water from entering the cavity A from the gap between the valve core 5 and the hole wall of the end positioning hole 315 by arranging the first sealing ring 504, so that the water pressure in the cavity A is relatively low, and it is more labor-saving to push the valve core 5 in the direction of the first end by the pushing protrusion 403.

[0061] When the pushing protrusion 403 releases the valve core 5 to close the water outlet 311, the return spring 6 applies an elastic force to the valve core 5 to push the valve core 5 to move in the direction from the first end to the second end, but since the water pressure in the cavity A of the first end is lower than the water pressure of the second end, a larger elastic force needs to be applied by the return spring 6 to push the valve core 5. To solve this problem, the valve core 5 is provided with a through hole 503 passing through from the first end to the second end, so that the water pressures of the first end and the second end of the valve core 5 are balanced, and thus the return spring 6 does not need to apply a larger elastic force.

[0062] In the example shown in FIG. 8 and FIG. 10, the second end of the valve core 5 is provided with a second sealing ring 505 on the outer peripheral surface, and the valve body 3 is provided with a water outlet passage 312 corresponding to each water outlet 311 (in combination with FIG. 6 and FIG. 7), when the valve core 5 is moved to enter the water outlet passage 312 under the elastic force of the return spring 6, the second sealing ring 505 seals the gap between the valve core 5 and the wall surface of the water inlet passage 312, thereby closing the water outlet passage 312, and the water outlet 311 corresponding to the water outlet passage 312 does not outlet water, as shown in FIG. 6. When the rotating shaft 4 is rotated to make one of the pushing protrusions 403 push the protruding part 502 of the valve core 5, so that the second end of the valve core 5 moves to a position to open the water outlet passage 312, the water in the valve body 3 outlets from the corresponding water outlet 311, as shown in FIG. 7.

[0063] In this example, the first seal ring 504 is arranged on the outer periphery of the first end of the valve core 5, so that water is prevented from entering the cavity A from the gap between the valve core 5 and the hole wall of the end positioning hole 315, and thus water cannot flow from the cavity A along the through hole 503 of the valve core 5 to the water outlet 311 when the water outlet 311 is closed.

[0064] The specific process of water outlet switching will be described below in connection with the water outlet switching assembly provided in FIGS. 1-11.

[0065] When the push-torque 9 of the water outlet switching assembly is in the first control position, the water outlet switching assembly is in the state shown in FIGS. 8 and 9, at which time the first push protrusion 403a on the rotating shaft 4 pushes the first valve core 5a to the position of opening the first water outlet 311a (i.e., pushes the first valve core 5a upward in the drawing). When the connecting pipe 2 is connected to water, water enters the internal cavity of the valve body 3 from the water inlet pipe 321 of the valve body 3, and the water in the internal cavity of the valve body 3 flows out from the first water outlet 311a;

[0066] When the push-torque 9 is pushed to the second control position, the push-torque 9 moves along the elongated slot 101 on the mounting body 1 and drives the push rod 8 to slide along the slide rail 201 of the connecting pipe 2, so that the push rod 8 pushes the rack structure 7 to engage with the toothed wheel 401 on the rotating shaft 4, the rotating shaft 4 rotates, the second push protrusion 403b on the rotating shaft 4 pushes the second valve core 5b to the position of opening the second water outlet 311b, and at the same time, the first push protrusion 403a releases the first valve core 5a, which moves to the position of closing the first water outlet 311a under the elastic force of the return spring 6. That is, the water outlet switching assembly is switched to the state shown in FIGS. 10-11.

[0067] Similarly, when the push-torque 9 is pushed to the third control position, the third push protrusion 403c pushes the third valve core 5c to the position of opening the third water outlet 311c, and at the same time, the second push protrusion 403b releases the second valve core 5b, which moves to the position of closing the second water outlet 311b under the elastic force of the return spring 6.

[0068] When the push-torque 9 is pushed to the fourth control position, the fourth push protrusion 403d pushes the fourth valve core 5d to the position of opening the fourth water outlet 311d, and at the same time, the third push protrusion 403c releases the third valve core 5c, which moves to the position of closing the third water outlet 311c under the elastic force of the return spring 6.

[0069] If the push-torque 9 is returned to the third control position, the second control position, or the first control position, the push-torque 9 can be pushed in the reverse direction.

[0070] The embodiment of the present application also provides a water outlet device, which comprises a water outlet switching assembly as described above and a water outlet body connected to the water outlet switching assembly.

[0071] The water outlet body is provided with a plurality of water outlet cavities, and each water outlet is supplied with water to one of the water outlet cavities. The water outlet body can be a shower head body, and the plurality of water outlet modes can be achieved by switching the water outlet through the water outlet switching assembly.
