[0026] See also Figure 1-3The nozzle assembly 1000 includes a nozzle 1, a liquid inlet connector 2 and a fastening assembly 3. The nozzle 1 includes a first end 11 and a second end 12, which are arranged along a first direction. The nozzle 1 is provided with a liquid channel a extending along the first direction, the first end 11 is used to connect to a first liquid supply source, and the second end 12 is used to discharge the liquid. The side wall of the nozzle 1 is provided with a liquid inlet hole b, which is connected to the liquid channel a. The liquid inlet connector 2 is connected to the liquid inlet hole b, and the liquid inlet connector 2 is also used to connect to a second liquid supply source. The fastening assembly 3 is connected to the liquid inlet connector 2, and the fastening assembly 3 is fixed to the outer peripheral wall of the nozzle 1 to fix the liquid inlet connector 2 to the nozzle 1.

[0027] In some embodiments, the spray head assembly 1000 is applied to a toilet, the first liquid supply source is a tap water supply source, and the second liquid supply source is a storage container for the foaming liquid.

[0028] In some embodiments, the toilet is a smart toilet.

[0029] In some embodiments, the toilet includes a water diverter valve A, and the nozzle 1 serves as a side flush nozzle. The second end 12 of the nozzle 1 is connected to the water outlet A1 of the water diverter valve A, and is connected to a tap water supply source as a first liquid supply source through the water diverter valve A. The liquid inlet connector 2 is connected to a storage container of a foaming liquid as a second liquid supply source. One end of the liquid inlet connector 2 is inserted into the liquid inlet hole b located on the side wall of the nozzle 1, and the liquid inlet connector 2 is fixed to the outer peripheral wall of the nozzle 1 through a fastening assembly 3.

[0030] In a conventional smart toilet, a connecting pipe is added between the nozzle 1 and the water diversion valve A along the axial direction of the nozzle 1, and the liquid inlet connector 2 is arranged on the side wall of the transfer tube. Compared with the conventional smart toilet, one end of the liquid inlet connector 2 of the nozzle assembly 1000 of the embodiment of the present application is inserted into the liquid inlet hole b located on the side wall of the nozzle 1, and the liquid inlet connector 2 is fixed to the outer peripheral wall of the nozzle 1 through the fastening assembly 3, eliminating the transfer tube, and the liquid inlet connector 2 is directly fixed to the outer peripheral wall of the nozzle 1 through the fastening assembly 3, so that the space occupied along the axial direction of the nozzle 1 is small.

[0031] In some embodiments, the fastening assembly 3 also includes a sealing ring (not shown), which is sleeved on the outer peripheral wall of the liquid inlet connector 2, and is used to seal the liquid inlet connector 2 with the liquid inlet hole b to prevent the liquid from flowing out through the gap between the liquid inlet hole and the outer peripheral wall of the liquid inlet connector 2.

[0032] See also Figure 2-4In some embodiments, the fastening assembly 3 includes an enclosure 31 and a bending portion 32. The enclosure includes a third end 311 and a fourth end 312. A bending portion 313 adapted to the outer wall of the nozzle 1 is provided between the third end 311 and the fourth end 312. A portion of the nozzle 1 is provided in the bending portion 313. The liquid inlet connector 2 is provided in the enclosure 31 and inserted into the liquid inlet hole b. The bending portion 32 includes a fifth end 32a and a sixth end 32b. The fifth end 32a is connected to the third end 311. The sixth end 32b is provided with a first clamping structure. The fourth end 312 is provided with a second clamping structure. The fifth end 32a can rotate relative to the third end 311 so that the first clamping structure is clamped or separated from the second clamping structure. When the first clamping structure is clamped to the second clamping structure, the enclosure 31 and the bending portion 32 are enclosed and fixed to the outer wall of the nozzle 1.

[0033] In some embodiments, see Figure 3 and Figure 4 The enclosing portion 31 is generally in the shape of an arc plate, the liquid inlet hole b is arranged on the side wall of the cylindrical portion of the nozzle 1, and the enclosing portion 31 is arranged around the outer surface of the cylindrical portion of the nozzle 1.

[0034] In some embodiments, a first recess 33 is provided at the connection between the fifth end 32a and the third end 311, and a thickness t1 of the first recess 33 is smaller than a thickness t2 of the fifth end 32a and a thickness t3 of the third end 311. Since the thickness t1 of the first recess 33 is smaller, the first recess 33 is more likely to bend, so that the fifth end 32a can rotate relative to the third end 311 through the bending deformation of the first recess 33.

[0035] In some embodiments, the fastening component 3 is made of elastic material, and the elastic material includes but is not limited to plastic.

[0036] It is understandable that the fifth end 32a is not limited to being able to rotate relative to the third end 311 by providing the first recess 33. For example, in some other embodiments, the fifth end 32a and the third end 311 can be rotatably connected by a hinge.

[0037] In some embodiments, the liquid inlet hole b is located on the side wall of the nozzle 1 facing the bent portion 313. When the first clamping structure is clamped to the second clamping structure, along the axial direction of the liquid inlet hole b, the nozzle 1 abuts against the liquid inlet connector 2, and the bent portion 32 abuts against the side of the outer peripheral wall of the nozzle 1 facing away from the liquid inlet hole b. The bent portion 32 abuts against the side of the outer peripheral wall of the nozzle 1 facing away from the liquid inlet hole b, and the bent portion 32 can apply a force opposite to the direction in which the liquid inlet connector 2 is inserted into the liquid inlet hole b toward the nozzle 1, thereby allowing the liquid inlet connector 2 to be firmly inserted into the liquid inlet hole b.

[0038] In some embodiments, the bending portion 32 includes a first plate 321, a second plate 322 and a third plate 323 connected in sequence, the first plate 321 is connected to the third end 311, the first plate 321 can rotate relative to the third end 311, the second plate 322 is provided with a first clamping structure, and the third plate 323 is inclined relative to the second plate 322. One end of the first plate 321 connected to the third end 321 constitutes the fifth end 32a, and part of the second plate 322 and the third plate 323 constitute the sixth end 32b. When the first clamping structure is clamped to the second clamping structure, along the axial direction of the liquid inlet hole b, the first plate 321 abuts against the side of the outer peripheral wall of the spray head 1 facing away from the liquid inlet hole b, the second plate 322 abuts against the fourth end 312, and the third plate 323 is separated from the enclosed portion 31. The third plate 323 is used to provide a position for applying force for the operator to facilitate the clamping of the second clamping structure of the second plate 322 to the first clamping structure, and the separation of the second clamping structure of the second plate 322 from the first clamping structure. When installing the fastening assembly 3, by pressing the third plate 323, the second plate 322 can be driven to rotate toward the fourth end 312, thereby clamping the second clamping structure to the first clamping structure. When disassembling the fastening assembly, by pulling the third plate 323, the second plate 322 can be driven to rotate in a direction away from the fourth end 312, thereby separating the second clamping structure from the first clamping structure.

[0039] In some embodiments, the first plate 321 is in a flat plate shape.

[0040] In some embodiments, the first clamping structure is a clamping hole 3221, and the second clamping structure is a clamping protrusion 3121, which is disposed on the outer wall of the fourth end 312 facing away from the nozzle 1. The clamping protrusion 3121 is inserted into the clamping hole 3221 to achieve clamping fixation.

[0041] In some embodiments, the second plate 322 is capable of rotating relative to the first plate 321 .

[0042] In some embodiments, a second recess 324 is provided at the connection between the first plate 321 and the second plate 322, and a thickness t4 of the second recess 324 is smaller than a thickness t5 of the first plate 321 and a thickness t6 of the second plate 322. Since the thickness t4 of the second recess 324 is smaller, the second recess 324 is more likely to bend, so that the second plate 322 can rotate relative to the first plate 321 through the bending deformation of the second recess 324.

[0043] In some embodiments, when the locking protrusion 3121 is inserted into the locking hole 3221, the inner wall of the locking hole 3221 abuts against the surface 3121a of the locking protrusion 3121 facing away from the first plate 321, and the friction force between the inner wall of the locking hole 3221 and the surface 3121a of the locking protrusion 3121 facing away from the first plate 321 prevents the locking protrusion 3121 from detaching from the locking hole 3221.

[0044] See also Figure 5 and Figure 6 In some embodiments, the first clamping structure includes a plurality of first clamping teeth 3222 arranged in sequence, and the second clamping structure includes a plurality of second clamping teeth 3122 arranged in sequence, the first clamping teeth 3222 are arranged on the side wall of the sixth end 32b facing the nozzle 1, and the second clamping teeth 3122 are arranged on the outer wall of the fourth end 312 facing away from the nozzle 1, and a first clamping tooth 3222 is clamped to a second clamping tooth 3122.

[0045] In some embodiments, the wall surface of the first plate 321 facing the nozzle 1 is adapted to the outer wall of the nozzle 1 .

[0046] In some embodiments, the first plate 321 is generally in the shape of an arc plate.

[0047] In some embodiments, the first recess 33 is arranged to protrude outward from the center of the nozzle 1, and the first recess 33 can produce elastic deformation along the circumference of the nozzle 1. The first recess 33 can provide elastic deformation capability, so that when the fastening assembly 3 is installed, the bending portion 32 and the enclosing portion 31 can expand along the circumference of the nozzle 1 to adapt to the outer diameter of the nozzle 1, and finally elastic recovery occurs after the first clamping structure is clamped to the second clamping structure, so that the fastening assembly 3 can be tightly buckled on the outer peripheral wall of the nozzle 1.

[0048] See also Figure 6 In some embodiments, the first concave portion 33 is an arc-shaped structure obtained by bending the bending portion 32 outward along the center of the nozzle 1. It can be understood that the first concave portion 33 is not limited to being an arc-shaped structure. In some other embodiments, the first concave portion 33 is also V-shaped.

[0049] It can be understood that the fastening assembly 3 is not limited to the above-mentioned structure including the enclosing portion 31 and the bending portion 32, which is fixed to the nozzle 1 in a clamping manner. For example, in some other embodiments, the fastening assembly 3 can also include an enclosing portion 31, and the third end 311 and the fourth end 312 of the enclosing portion 31 extend to the side of the nozzle 1 facing away from the liquid inlet connector 2, and the third end 311 and the fourth end 312 are fastened together by fastening bolts, and the enclosing portion 31 is clamped and fixed to the outer wall of the nozzle 1 under the action of the fastening bolts, or the fastening assembly 3 can also be a throat clamp, a cable tie or other structure.
