When the limiting plate 27 is removed, it is also convenient to disassemble, replace and clean the piston rod 23.

[0048] In addition, a connecting pipe 222 is provided on the peripheral surface of the output end of the water passing member 22 for installing the nozzle 26; the nozzle 26 is provided with a plurality of strip-shaped water outlet holes to output blade water.

[0049] A third water inlet 35, a fourth water inlet 36 and a third water outlet 37 are provided on the bottom surface of the valve body 3. A fourth water outlet 38 is provided on the side surface of the valve body 3. The third water inlet 35 and the fourth water inlet 36 are respectively communicated with the first water outlet 31 and the second water outlet 32. The third water outlet 37 is communicated with the first water inlet 33. The fourth water outlet 38 is communicated with the second water inlet 34. Corresponding water channels are arranged inside the valve body 3. The end parts of the cold water pipe 6, the hot water pipe 7 and the water outlet pipe 8 are respectively connected in the third water inlet 35, the fourth water inlet 36 and the third water outlet 37. The input end of the cup washer 2 is communicated with the fourth water outlet 38. The third water inlet 35 serves as the input end of the first water outlet 31, the fourth water inlet 36 serves as the input end of the second water outlet 32, and the third water outlet 37 serves as the output end of the first water inlet 33. All of them are arranged at the bottom of the valve body 3, which is convenient for water pipe connection.

[0050] Furthermore, a sunken water passing groove 39 is provided on the peripheral surface of the valve body 3. The water passing groove 39 is communicated with the second water inlet 34. A sealing ring member 9 is hermetically covered between the two sides of the opening of the water passing groove 39. The fourth water outlet 38 is provided on the sealing ring member 9. Thus, a water channel is formed by first designing a sunken water passing groove 39 on the peripheral surface of the valve body 3 and then closing it with the sealing ring member 9. It is easier to realize the communication between the second water inlet 34 and the fourth water outlet 38 in the water channel design.

[0051] Secondly, the present utility model further includes a valve core assembly; a plurality of first convex teeth 310 are provided on the circumferential surface of the valve body 3, and the water passing groove 39 and the first convex teeth 310 are located at adjacent positions in the axial direction of the valve body 3; the sealing ring member 9 is rotatably sleeved on the circumferential surface of the valve body 3 in a dynamic sealing manner and covers the water passing groove 39, so that a water channel communicating the second water inlet 34 and the fourth water outlet 38 is formed between the valve body 3 and the sealing ring member 9; the water inlet end of the water passing member 22 is relatively fixed to the fourth water outlet 38, a water passing channel 223 is provided therein, and an installation hole 224 communicating with the water passing channel 223 is provided on the surface of the water passing member 22; the valve core assembly is rotatably and movably fitted in the installation hole 224 to control the on-off between both ends of the water passing channel 223; a plurality of second convex teeth 201 meshing with the first convex teeth 310 are provided on the circumferential surface of the end portion of the valve core assembly exposed from the installation hole 224. By swinging the water passing member 22 left and right with the valve body 3 as the axis, the valve core assembly in the water passing member 22 can be linked through the meshing of the first convex teeth 310 and the second convex teeth 201, so that the valve core assembly realizes the on-off between both ends of the water passing channel 223. When the valve core assembly is in the open state, the valve body 3 supplies water to the cup washer 2 through the water passing groove 39 and the water passing channel 223 in sequence. When the valve core assembly is in the closed state, the water passing channel 223 cannot supply water, so that when the user swings the cup washer, the opening and closing of the water inlet end of the cup washer can be realized, and in the closed state, the situation that the user touches the button of the cup washer by mistake and gets wet by high-pressure water can be prevented.

[0052] In some embodiments of the above valve core assembly, at least one of the first convex teeth 310 on the circumferential surface of the valve body 3 and the second convex teeth 201 on the circumferential surface of the valve core assembly is distributed in a fan shape, that is, a complete gear is not formed, so that after the cup washer 2 rotates a certain angle, the second convex teeth 201 will no longer contact the first convex teeth 310. At this time, the internal valve core assembly will maintain the corresponding state and will not change until the second convex teeth 201 mesh with the first convex teeth 310 again after the subsequent swing of the water passing member 22.

[0053] In some embodiments of the above spool assembly, the spool assembly includes a rotating shaft member 20, a second spring 30, and two sealing balls 40; a second convex tooth 201 is provided on the circumferential surface of one end of the rotating shaft member 20, and the other end thereof is movably sealed and fitted in the mounting hole 224, and a cross hole 202 penetrating to the circumferential surface of the rotating shaft member 20 is provided; the second spring 30 is disposed in the cross hole 202, and sealing balls 40 are provided at both ends thereof. That is to say, the spool assembly is actually a sealing ball ball valve, and the communication between the water passage 223 and the mounting hole 224 is conducted or closed by the sealing ball 40 under the elastic force of the second spring 30, so as to realize the on-off between both ends of the water passage 223. In this embodiment, a buckle 203 is provided on the end surface of one end of the rotating shaft member 20, and the buckle 203 is hooked at the port of the mounting hole 224 to realize the relative fixation of the rotating shaft member 20 and the water passing member 22. In this embodiment, the sealing ball 40 is made of rubber material, and its elasticity can ensure the effects of sealing and leak prevention.

[0054] In some embodiments of the above spool assembly, the water passing member 22 includes a split water inlet member 22a and a water outlet member 22b for the processing and forming of parts; the water outlet end of the water inlet member 22a is embedded in the water inlet end of the water outlet member 22b and fixed by a C-shaped buckle 28.

[0055] Meanwhile, a through hole 320 for the water outlet pipe 8 to pass through is provided in the axial direction of the above valve body 3, so that the water outlet pipe 8 can extend upward into the elbow 10 of the faucet.

[0056] The above spool 4 is provided with a swing rod 41 for connecting the handle 5.
