At this time, the valve stem 6 cannot move back to the second direction B. When the locking member 9 rotates to the second position D under the action of external force, the locking part 10 disengages from the locking mating part 11 to unlock the valve stem 11. At this time, the valve stem 6 moves back to the second direction B under the elastic force of the elastic member 7.

[0030] The locking member 9 is provided with a limiting part 12. When the valve stem 6 moves to reset in the second direction B under the elastic force of the elastic member 7, the limiting part 12 abuts against the locking engagement part 11 to prevent the valve stem 6 from moving excessively.

[0031] The locking member 9 is provided with an operating part 13 for manually rotating the locking member 9 and moving the valve assembly a; when the enhanced wash function is turned on, the valve stem 6 is manually pulled out in the first direction A through the operating part 13, and then the locking member 9 is manually rotated through the operating part 13 to rotate the locking member 9 to the first position C to lock the valve stem 6; when the enhanced wash function is turned off, the locking member 9 is manually rotated through the operating part 13 to rotate the locking member 9 to the second position D to unlock the valve stem 6, and then the operating part 13 is released. At this time, the valve stem 6 is reset and moved in the second direction B under the elastic force of the elastic member 7.

[0032] The cleaning arm 2 is equipped with a movable channel 14, which is connected to the water outlet channel 4.

The elastic element 7 is sleeved on the second rod body 16, with one end of the elastic element 7 abutting against the first rod body 15 and the other end abutting against the inner wall of the reinforcing cleaning arm 2. The reinforcing cleaning arm 2 is provided with a through hole 17, and the second rod body 16 extends out of the reinforcing cleaning arm 2 at least partially through the through hole 17.

[0034] The second rod body 16 is provided with a mounting hole 18, and a rotating shaft 19 is installed in the mounting hole 18. The locking member 9 is provided with a rotating hole 20. The rotating shaft 19 is rotatably connected to the rotating hole 20 so that the locking member 9 is rotatably mounted on the second rod body 16.

[0035] The enhanced cleaning arm 2 includes a main body section 21 and a connecting pipe section 22 integrally set on one side of the main body section 21. The main body section 21 and the water inlet pipe 1 are set parallel to each other. This parallel layout makes the pipeline design simpler and smoother, reduces unnecessary bends, and is conducive to the stability of water flow and the maintenance of pressure. The connecting pipe section 22 is connected to the water inlet pipe 1. The water outlet channel 4 is set inside the main body section 21, and the connecting channel 3 is set inside the connecting pipe section 22. The water inlet pipe 1 is provided with a water inlet channel 23, which is connected to the connecting channel 3.

[0036] A connector 27 is provided near the other end of the water inlet pipe 1, and the end of the connecting pipe section 22 is connected to the connector 27.

[0037] The enhanced cleaning arm 2 also includes a movable pipe section 28 integrally mounted on the main body section 21, and a movable channel 14 is located within the movable pipe section 28.
