The nozzle body 2 has a water outlet, and the nozzle connector 1 has a water inlet connected to the water outlet. A first mating surface and a second mating surface are respectively provided at the connection between the nozzle body and the nozzle connector 1. A limiting squeezing part 3 is provided on the first mating surface, and a limiting mating part 4 is provided on the second mating surface; alternatively, a limiting mating part 4 is provided on the first mating surface, and a limiting squeezing part 3 is provided on the second mating surface. During the rotation of the nozzle body 2 within a preset angle range, the limiting squeezing part 3 and the limiting mating part 4 can mutually squeeze and rub against each other to prevent rotation. Through the squeezing and rubbing cooperation of the limiting mating part 4 and the limiting squeezing part 3 to prevent rotation, locking at any angle can be achieved, realizing stepless nozzle adjustment to meet the angle requirements for ensuring optimal flushing effect under different water pressures.

[0032] Please see Figures 1 to 4 Preferably, the limiting squeezing part 3 is arranged around the rotation center of the nozzle connector 1, and the limiting mating part 4 is arranged around the rotation center of the nozzle body 2; or, the limiting squeezing part 3 is arranged around the rotation center of the nozzle body 2, and the limiting mating part 4 is arranged around the rotation center of the nozzle connector 1. The limiting squeezing part 3 and the limiting mating part 4 mutually squeeze and rub against each other radially to prevent rotation. The distance between the squeezing side of the limiting squeezing part 3 and the rotation center is not equal to the distance between the squeezed side of the limiting mating part 4 and the rotation center. The different distances between the limiting mating part 4 and the limiting squeezing part 3 and the rotation center enable them to mutually squeeze and rub against each other to lock when they rotate relative to each other, thereby achieving stepless adjustment of the nozzle water outlet angle.

[0033] Please see Figures 1 to 4 Preferably, the limiting fitting part 4 is located on the outer periphery of the limiting squeezing part 3, and the inner side of the limiting fitting part 4 has a first rotation channel 5 between it and the rotation center of the nozzle body 2 for the limiting squeezing part 3 to move, and the outer side of the limiting squeezing part 3 has a second rotation channel 501 for the limiting fitting part 4 to move relative to it; or, the limiting fitting part 4 is located on the inner periphery of the limiting squeezing part 3, and the inner side of the limiting squeezing part 3 has a second rotation channel 501 between it and the rotation center of the nozzle body 2 for the limiting fitting part 4 to move, and the outer side of the limiting fitting part 4 has a first rotation channel 501 for the limiting squeezing part to move. The first rotation channel 5 and the second rotation channel 501 enable the limiting squeezing part 3 and the limiting fitting part to engage and rotate relative to each other, so that the nozzle body 2 and the nozzle connector 1 can rotate relative to each other, and ensure that the limiting squeezing part 3 can accurately engage with the limiting fitting part 4 to achieve infinite locking of the nozzle water outlet angle.

[0034] Please see Figures 1 to 4Preferably, the limiting compression part 3 has a compression section 31 and a relief section 32. The relief section is in contact with or isolated from the limiting mating part 4.

The relief section 32 is used to allow the installation of the limiting mating part 4. The relief section 32 will not contact the limiting mating part 4 or only contact it, and no compression or slight pressure will occur, so that the limiting mating part 4 can be smoothly screwed into the second rotating channel 501 and compress against the limiting compression part 3. This allows the limiting compression part 3 to be smoothly installed into the rotating channel 5, and the limiting compression part 3 and the limiting mating part 4 can be connected to achieve compression limiting locking.

[0035] Please see Figures 1 to 4 Preferably, the limiting extrusion part 3 has an annular structure; when the first rotating channel 5 is located outside the limiting mating part, the distance between the inner circumference of the yielding section 32 and the rotation center of the nozzle body 2 is greater than the distance between the extrusion section 31 and the rotation center of the nozzle body 2, and the distance between the extrusion section 31 and the rotation center of the nozzle body 2 is less than the distance between the contact side of the limiting mating part 4 and the rotation center of the nozzle body 2; when the first rotating channel 5 is located inside the limiting mating part 4, the distance between the outer circumference of the yielding section 32 and the rotation center of the nozzle body 2 is less than the distance between the extrusion section 31 and the rotation center of the nozzle body 2, and the distance between the outer circumference of the extrusion section 31 and the rotation center of the nozzle body 2 is greater than the distance between the contact side of the limiting mating part 4 and the rotation center of the nozzle body 2; the limiting mating part 4 is a rubber pad. The limiting and squeezing part 3 is a retaining ring. The yielding section 32 and the squeezing section 31 are at least two arc-shaped sections of different diameters provided on the retaining ring, which facilitates the easy insertion of the limiting and squeezing part 3 into the rotating channel 5. After rotation, the limiting fitting part 4 and the squeezing section 31 squeeze and rub against each other to lock the water outlet angle. Of course, the yielding section 32 can also be a notch formed on the limiting and squeezing part 3. The retaining ring can be elliptical or polygonal.

[0036] Please see Figures 1 to 5Preferably, the nozzle body 2 includes a first connecting portion 201 and a first cover 202, and the nozzle connector includes a second connecting portion 101 and a second cover 102. The first mating surface is disposed on the first cover 202, and the second mating surface is disposed on the second cover 102. The first connecting portion 201 and the second connecting portion 101 are tubular. The first connecting portion 201 is sleeved inside or outside the second connecting portion 101. The first cover 202 extends radially around the first connecting portion 201, and the second cover 102 extends radially around the second connecting portion 101. The first cover 202 and the second cover 102 cover each other. The second connecting portion 101 has an inlet at one end away from the second cover 102. The first cover 202 has an outlet and an outlet channel 203. The outlet and the outlet channel 203 are connected. The outlet channel 203 is connected to the first connecting portion 201, and the first connecting portion 201 is connected to the second connecting portion 101. The nozzle body has a first connecting part 201 and a first cover 202, and the nozzle connector 1 has a second connecting part 101 and a second cover 102, which facilitates the nozzle body 2 and the nozzle connector 1 to be connected together. The first cover 202 and the second cover 102 form a cover structure to enclose the limiting extrusion part 3 and the limiting elastic mating part 4, making the appearance more aesthetically pleasing.

[0037] Please see Figure 1 , Figures 5 to 9 Preferably, one of the nozzle connector 1 and the nozzle body 2 is provided with a first axial limiting part 6, and the other of the nozzle connector 1 and the nozzle body 2 is provided with a second axial limiting part 7, the first axial limiting part 6 and the second axial limiting part 7 cooperating with each other. The first axial limiting part 6 and the second axial limiting part 7 cooperating on the nozzle connector 1 and the nozzle body 2 prevent the nozzle body 2 from falling off after the nozzle connector 1 and the nozzle body 2 are assembled.

[0038] Please see Figure 1 , Figures 5 to 9 Preferably, the nozzle body 2 includes a first connecting portion 201, and the nozzle connector includes a second connecting portion 101. The first connecting portion 201 is sleeved inside or outside the second connecting portion 101. A first axial limiting portion 6 is provided circumferentially on either the first connecting portion 201 or the second connecting portion 101, and a second axial limiting portion 7 is provided axially on the other side of either the first connecting portion 201 or the second connecting portion 101. The first axial limiting portion 6 is a limiting groove, and the second axial limiting portion 7 is a limiting rib. The limiting rib is slidably disposed in the limiting groove. The structure of the limiting rib embedded in the limiting groove prevents the nozzle body 2 from being pushed off axially by water pressure.

[0039] Please see Figure 1 , Figures 5 to 9Preferably, at least one end of the limiting slide groove is provided with a first stop 8 to restrict the limiting rib from dislodging from the limiting slide groove in the circumferential direction. The first stop 8 or the limiting rib is an elastic or flexible element, allowing the limiting rib to pass over the first stop 8 and enter the limiting slide groove. The first stop 8, cooperating with the limiting rib, prevents the limiting rib from dislodging from the first limiting slide groove and limits the rotation range of the nozzle. The limiting rib or the first stop 8 is an elastic or flexible element, facilitating mutual compression and deformation during assembly, allowing the limiting rib to enter the limiting slide groove. The limiting slide groove also includes a second stop 9, where the limiting rib and the second stop 9 are mutually limitingly engaged in the axial direction. The second stop 9 is used to prevent the limiting rib from dislodging from the limiting slide groove in the axial direction. The limiting slide groove includes at least two sets of first stop plates and second stop 9, with the first stop 8 and the second stop 9 forming the first limiting slide groove.

[0040] Please see Figures 1 to 4 Preferably, the angle between the two ends of the clearance section 32 and the line connecting the rotation axis of the nozzle body 2 is greater than the angle by which the nozzle body 2 can rotate relative to the nozzle connector 1. The angle between the two ends of the clearance section 32 is greater than the rotatable angle of the nozzle body 2, ensuring that the limiting locking range of the limiting fitting part 4 and the limiting squeezing part 3 covers the maximum rotation range of the nozzle. In this embodiment, the axial limiting part cooperates with the limiting fitting part and the limiting squeezing part to achieve better performance.

[0041] Please see Figures 1 to 4 Preferably, the limiting compression part 3 and / or the limiting fit part 4 are elastic rubber pads, allowing them to deform and compress against each other to achieve an interference fit and frictional anti-rotation. Please refer to [link / reference]. Figure 1 , Figures 5 to 9 Preferably, the outer peripheral surface of the nozzle body 2 is provided with an axial guide groove 10, the guide groove 10 is connected to the limiting groove, the size of the guide groove 10 matches the size of the limiting rib, the connection between the limiting groove and the guide groove 10 is provided with a first stop part 8, the guide groove 10 guides the limiting rib to accurately enter the limiting groove, avoiding misalignment during assembly, the first stop part 8 of the second limiting rib is provided at the connection between the guide groove 10 and the limiting groove to form a mechanical block, preventing the limiting rib from coming out of the limiting groove, and preventing the nozzle body 2 and the nozzle connector 1 from rotating from the limiting groove to the guide groove 10 during use after assembly, so as to avoid the nozzle body 2 and the nozzle connector 1 from being pushed apart by the water flow.

[0042] Please see Figures 1 to 12Additionally, a toilet 15 is provided, including a bowl, with a rotatable nozzle as described above located on the upper rear side of the bowl. It also includes an anti-rotation plate 11, one end of which is connected to the toilet 15, and the other end having a clearance hole through which the nozzle connector 1 passes. A mounting nut 12 and a sealing gasket 13 are respectively provided on both sides of the clearance hole. A sealing ring 14 is also provided between the circumferential surfaces of the connection between the nozzle body 2 and the nozzle connector 1. The anti-rotation plate 11 is fixed to the toilet 15 body, completely eliminating the slight self-rotation of the nozzle caused by water flow impact; the sealing ring 14 and the sealing gasket 13 together prevent leakage at the interface, providing multiple seals to adapt to high water pressure conditions.

[0043] The working principle of this utility model is as follows:

[0044] First, fix the nozzle connector 1 to the toilet 15 using the anti-rotation plate 11, mounting nut 12, and sealing gasket 13. Then, install the nozzle body 2. First, align the limiting rib on the nozzle connector 1 with the guide groove 10, and push the nozzle body 2 to push the limiting rib into the guide groove 10. Then, rotate the nozzle body 2 so that when the nozzle connector 1 and / or the nozzle body 2 slightly deform, the limiting rib can pass over the first stop 8 and enter the limiting groove. Due to the obstruction of the first stop 8, the limiting rib cannot come out of the limiting groove, thus limiting the movement. The rib can move along the limiting slide groove to adjust the water outlet angle of the nozzle body 2; and due to the squeezing and frictional cooperation between the limiting squeezing part 3 and the limiting mating part 4, within the sliding range of the limiting rib in the limiting slide groove, the limiting mating part 4 and the limiting squeezing part 3 are in an interference fit state, which can lock any angle. After adjusting the water outlet angle of the nozzle body 2, the limiting squeezing part 3 and the limiting mating part 4 squeeze each other to achieve a tight fit, thereby locking the water outlet angle of the nozzle body 2 and preventing the nozzle body 2 from shaking and loosening.

[0045] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
