[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0023] Please refer to Figures 1 to 5 A water diverter valve comprises a shell 1 and a switching member 2, wherein the shell 1 is provided with a first water outlet 18 and a water inlet 17 at intervals in the length direction thereof, and a water retaining ring 111 is provided on the outer wall of the shell 1 between the water inlet 17 and the first water outlet 18; the switching member 2 is movably arranged in the shell 1 along the length direction of the shell 1; the switching member 2 is provided with a first sealing ring 22 and a second sealing ring 23 respectively at both ends in the length direction thereof, which are against the inner wall of the shell 1; and a second water outlet 19 is provided on the end face of the shell 1.

[0024] From the above description, it can be seen that the beneficial effects of the utility model are: the first water outlet 18, the second water outlet 19 and the water inlet 17 formed by a single shell 1, that is, the valve core, cooperate with the switching member 2, so that the water distribution structure of the water diversion valve is simplified, and no additional shell structure or pipe wall at the installation location is required to cooperate to form a water path for switching; the second water outlet 19 design on the end face of the shell 1 effectively utilizes the space of the shell 1 compared with the side water outlet, forms water outlets in different directions and ensures the water outlet flow rate; when in use, the second sealing ring 23 of the switching member 2 is moved and switched on the inner wall of the shell 1 between the first water outlet 18 and the water inlet 17 or between the water inlet 17 and the second water outlet 19, so as to realize the conduction between the water inlet 17 and the first water outlet 18 or the second water outlet 19, and the first sealing ring 22 is set to prevent water from flowing out from the other end of the shell 1.

[0025] Furthermore, a limit block 110 is provided in the middle of the second water outlet 19 , and a plurality of ribs are connected between the limit block 110 and the inner wall of the shell 1 ; a return spring is provided between the switching member 2 and the limit block 110 .

[0026] It can be seen from the above description that the switching and resetting of the switching member 2 is achieved by the setting of the return spring; in addition, the limit block 110 serves as a limit structure of the return spring so that the return spring can remain positioned without deviation when it is mounted thereon; through the rib design of the limit block 110 and the inner wall of the shell 1, on the one hand, the setting of the limit block 110 at the second water outlet 19 is ensured, and on the other hand, the space between the ribs is used to ensure sufficient water flow area.

[0028] As can be seen from the above description, the other end of the return spring abuts against the switching body 21 of the switching member 2, and the switching body 21 guides the expansion and contraction of the return spring while fixing the return spring.

[0029] Furthermore, it also includes a pressing piece 3, the shell 1 is step-shaped, and includes a connected pressing body 12 and a water flow body 11, the diameter of the pressing body 12 is larger than the diameter of the water flow body 11; the switching piece 2 is movably arranged in the water flow body 11; the pressing piece 3 is arranged in the pressing body 12, and the driving end of the pressing piece 3 is connected to the switching piece 2.

[0030] From the above description, it can be seen that the switching member 2 is driven to move in the water-passing body 11 of the shell 1 by pressing the pressing member 3; the stepped design of the shell 1 is used to match the sizes of the pressing member 3 and the switching member 2, avoiding the need to modify and adapt pressing members 3 or switching members 2 of different sizes when using the same shell 1 size, and on the other hand, it can also quickly identify the pressing body 12 and the water-passing body 11, facilitating subsequent assembly.

[0031] Furthermore, one end of the water-passing body 11 close to the pressing body 12 extends toward the inside of the pressing body 12 .

[0032] From the above description, it can be known that when in use, the first sealing ring 22 of the switching member 2 is used to prevent the water flow in the water flow body 11 from flowing into the pressing body 12. This design can ensure the movement stroke of the switching member 2 while extending one end of the water flow body 11 to further ensure that when the internal components move too much, the first sealing ring 22 cannot maintain contact with the inner wall of the water flow body 11 to achieve water leakage prevention.

[0033] Furthermore, the pressing member 3 includes a fixed shell 31 , and the fixed shell 31 is clamped with the pressing body 12 .

[0034] It can be known from the above description that the fixing installation of the pressing member 3 and the housing 1 is achieved by the clamping connection between the fixed housing 31 of the pressing member 3 and the pressing body 12 .

[0035] Furthermore, a press-in groove 13 extending along the length direction is provided on the inner wall of the pressing body 12, and a sliding groove 14 extending circumferentially along the pressing body 12 is connected to one side of the press-in groove 13; a hook 16 is provided on the sliding groove 14; a press-in block 32 is provided on the outer wall of the fixed shell 31; the press-in block 32 is movable in the press-in groove 13 and the sliding groove 14; a matching groove 33 is provided on the press-in block 32 corresponding to the hook 16 of the sliding groove 14.

[0036] As can be seen from the above description, when installing the pressing member 3, the pressing block 32 on the fixed shell 31 of the pressing member 3 is aligned with the pressing groove 13 of the pressing body 12 and pressed in, and then the fixed shell 31 is rotated so that the pressing block 32 is transferred into the sliding groove 14; thereafter, the fixed shell 31 and the pressing body 12 are assembled by engaging the hook 16 on the sliding groove 14 with the slot 33 of the pressing block 32.

[0037] Furthermore, an observation port 15 is provided on the pressing body 12 corresponding to the sliding groove 14 .

[0038] It can be known from the above description that the clamping assembly status of the fixed housing 31 and the pressing body 12 can be directly observed through the observation port 15 corresponding to the sliding groove 14 .

[0041] like Figures 1 to 5As shown, the water diverter valve of this embodiment includes a housing 1, a switching member 2 and a pressing member 3. The housing 1 is stepped and includes a pressing body 12 and a water flow body 11 connected to each other. The diameter of the pressing body 12 is larger than the diameter of the water flow body 11. The water flow body 11 is provided with a first water outlet 18 and a water inlet 17 at intervals in the length direction thereof. A plurality of first water outlets 18 and water inlets 17 are provided on the circumferential surface of the same water flow body 11. A water retaining ring 111 is provided on the outer wall of the water flow body 11 between the water inlet 17 and the first water outlet 18. The water retaining ring 111 It is used to abut against the inner wall of the installation space of the water diversion valve to block the communication between the first water outlet 18 and the water inlet 17 outside the water flow body 11. Specifically, the water retaining ring 111 is provided with a third sealing ring 112, and the third sealing ring 112 abuts against the inner wall of the installation space of the water diversion valve; in addition, the outer walls at both ends of the water flow body 11 are respectively provided with a fourth sealing ring 113 and a fifth sealing ring 114, which abut against the inner wall of the adjacent installation space through the fourth sealing ring 113 and the fifth sealing ring 114 to ensure that the water flow can flow along the designed water inlet and outlet without losing from the gap between the parts. In this embodiment, the fifth sealing ring 114 is arranged on the end face of the water flow body 11 corresponding to the second water outlet 19.

[0045] Working principle: After the water diverter valve is installed, press the pressing part 3 to move the second sealing ring 23 of the switching part 2 to between the first water outlet 18 and the water inlet 17. At this time, the water flowing into the water inlet 17 can only flow out toward the second water outlet 19 on the end face of the shell 1 due to the obstruction of the water retaining ring 111 on the outside of the shell 1 and the obstruction of the second sealing ring 23 on the inside.

[0046] Then, the pressing member 3 is pressed again to reset the switching member 2 under the action of the return spring; when it is necessary to switch another water path, the pressing member 3 is pressed to move the second sealing ring 23 of the switching member 2 to between the water inlet 17 and the second water outlet 19. At this time, the water flowing into the water inlet 17 can only flow out toward the first water outlet 18 on the side of the shell 1 due to the obstruction of the water retaining ring 111 on the outside of the shell 1 and the obstruction of the second sealing ring 23 on the inside.

[0047] To summarize, the water diversion valve provided by the utility model simplifies the water diversion structure of the water diversion valve through the cooperation of the first water outlet, the second water outlet and the water inlet formed by a single shell, i.e., the valve core, and the switching member, and no additional shell structure or pipe wall at the installation location is required to cooperate to form a water path for switching; the second water outlet design on the end face of the shell effectively utilizes the shell space compared to the side water outlet, forms water outlets in different directions and ensures the water outlet flow rate; when in use, the second sealing ring of the switching member is moved and switched on the inner wall of the shell between the first water outlet and the water inlet or between the water inlet and the second water outlet, so as to realize the conduction between the water inlet and the first water outlet or the second water outlet, and the first sealing ring is set to prevent water from flowing out from the other end of the shell.
