[0041] like Figure 2 to Figure 10 As shown, the sliding seat 53 includes a connecting plate 533 and a driving plate 531 fixed to the upper end of the connecting plate 533, and a limiting plate 532 fixed to the lower end of the connecting plate 533. A sealing sliding buckle is inserted and fixed in the middle of the connecting plate 533 to fit the actuating rod 54 in the closing tube 521. The driving plate 531 touches the upper end of the closing tube 521 and fits with the closing tube 521. The limiting plate 532 touches the lower end of the closing tube 521 and fits with the closing tube 521. A top pressure ring 55 is connected to the pipe opening connecting the closing tube 521 and the bottom pipe 523. A water gap 550 is formed between the side walls at the bottom end of the top pipe 522 for the water flow in the bottom pipe 523 to flow into the top pipe 522; the end of the actuating rod 54 extends into the interior of the top pressure ring 55, and the circumferential protrusion of the actuating rod 54 forms a top pressure convex edge 541, and the inner edge surface of the top pressure ring 55 is provided with a stop ring surface 551.

[0042] like Figure 8 to Figure 10 As shown, a shaft sleeve ring 56 for press-fitting the top pressure ring 55 at the pipe mouth is sleeved in the closing tube 521, the shaft sleeve ring 56 has a shaft hole 561 for sealing and sliding cooperation with the actuating rod 54, the tail end of the shaft sleeve ring 56 has a mounting ring 562 which forms a stepped groove 563 with the shaft sleeve ring 56, and a return spring 5211 sleeved on the outside of the mounting ring 562 is provided between the shaft sleeve ring 56 and the connecting plate 533, one force-bearing end of the return spring 5211 is pressed against the bottom of the stepped groove 563, and the other force-bearing end is pressed against the inner side surface of the connecting plate 533, so as to provide the actuating rod 54 with a tendency to move away from the top pressure ring 55.

[0043] like Figure 2 and Figure 3 , Figure 8 to Figure 10 As shown, the lower end of the upper connecting pipe 512 extends radially inward to form a lifting ring 514, and a lifting ring groove 515 is formed between the lifting ring 514 and the pipe wall of the upper connecting pipe 512 for the bottom of the water-dividing chamber seat 40 to be inserted and placed; the bottom of the water-dividing chamber seat 40 has a rotating part 43, and the lifting ring 514 is provided with a rotating hole 516 that rotatably cooperates with the rotating part 43.

[0044] like Figure 4 , Figure 8 to Figure 10 As shown, a U-shaped limiting fork 45 is inserted into the limiting ring groove 431 opened on the side of the rotating part 43. Through the setting of the limiting fork 45, the axial movement of the rotating part 43 relative to the rotating hole 516 can be avoided, thereby improving the installation stability of the structure; a gear 517 is embedded in the rotating part 43, and vertical plates 534 are fixedly connected to the two opposite long sides of the upper end of the driving plate 531, and a clearance groove 538 for the gear 517 to avoid space is formed between the two vertical plates 534; one of the vertical plates 534 has a rack 535 meshing with the gear 517 on its inner side; a button part 536 extending out of the side plate 32 is fixedly installed on the end face of the connecting plate 533.

When the hooks 5323 are hooked into the hook grooves 621, the flat plate 61 presses the cross bar 5373 against the lower end surface of the limiting plate 532 to prevent the elastic member 537 from detaching from the limiting plate 532.

[0046] like Figure 5 to Figure 7 As shown, the locking groove 70 includes a first stroke groove 71, a first path groove 72, a second path groove 73 and a second stroke groove 74 which are arranged in a closed loop and connected end to end in sequence. A blocking step 76 is formed at the connection between the first path groove 72 and the second path groove 73, and a blocking step 75 is formed at the connection between the first stroke groove 71 and the second stroke groove 74; when the water diversion chamber seat 40 rotates to the first water outlet state, the locking rod 5372 slides from the second path groove 73 and the second stroke groove 74 into the first stroke groove 71, and is blocked and limited by the blocking step 75; when the water diversion chamber seat 40 rotates to the second water outlet state, the locking rod 5372 slides from the first stroke groove 71 and the first path groove 72 into the second path groove 73, and is blocked and limited by the blocking step 76.

[0048] When switching to the first water outlet state, the button portion 536 is pressed, and the actuating rod 54 overcomes the elastic force of the return spring 5211 and moves toward the direction of the top pressure ring 55 to press the stop pressure convex edge 541 against the stop ring surface 551, so as to press the top pressure ring 55 tightly against the bottom edge side wall surface of the top pipe 522, and the water gap 550 is closed, and the water flow is blocked and cannot flow into the water diversion chamber seat 40. During this process, the rack 535 is meshed with the gear 517 to drive the water diversion chamber seat 40 to rotate 180 degrees, and the first water outlet 411 on the first cavity 41 is aligned with the water outlet hole 311 and connected, and the first and second inlet When the water inlet 412 is aligned and connected with the pipe body 511, the buckle rod 5372 on the limit plate 532 is blocked by the blocking step 7575 to limit the water-dividing chamber seat 40 in the first water outlet state. At this time, the pressure on the button portion 536 is removed, and the actuating rod 54 slides away from the top pressure ring 55 under the elastic force of the return spring 5211, and a water gap 550 is formed between the top pressure ring 55 and the bottom side wall of the top pipe 522. The water flow input by the water inlet valve 20 can enter the first cavity 41 through the connecting seat 52 and the connecting pipe 51 and complete the water outlet from the first water outlet 411. The process of switching to the second water outlet state is similar to the above process, so it will not be repeated here.

[0049] The above embodiments are only used to illustrate the present invention, not to limit the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the scope of the present invention and be defined by the claims.
