[0036] The water supply pipe 2 extends vertically, and a water outlet 21 is arranged on the water supply pipe 2. The spray arm 3 extends transversely and is arranged on the water supply pipe 2. The spray arm 3 is provided with a water inlet 31 which is in communication with the water outlet 21. A water outlet 32 for spraying water is arranged on the wall of the spray arm 3 which is away from the water supply pipe 2. The water outlet 32 can be arranged at least two in the length direction of the spray arm 3, and one spray disc 4 is arranged at each spray arm 3.

[0037] The spray disc 4 is hollow inside, and the spray disc 4 is detachably connected with the spray arm 3 through a connecting structure.

[0038] The spray disc 4 is provided with a water passing hole 41 and a plurality of spray holes 42 which are in communication with the inside of the spray disc 4. The water passing hole 41 is in communication with the water outlet 32. The water passing area of the water outlet 32 is larger than that of each spray hole 42. When a thin water column is needed to be sprayed, the spray disc 4 is arranged at the water outlet 32, and water is sprayed from the spray holes 42. Because there are a plurality of spray holes 42, the spraying range is large. When a thick water column is needed to be sprayed, the spray disc 4 is removed, and water is sprayed from the water outlet 32, so as to adapt to the cleaning of different tableware.

[0039] The spray arm 3 is provided with an annular body 33 which surrounds the water outlet 32. The spray disc 4 is embedded in the annular body 33. The inner circumferential wall of the annular body 33 is provided with a positioning hole 331. The connecting structure comprises a positioning part 51 arranged on the spray disc 4. The positioning part 51 is detachably inserted into the positioning hole 331, so as to realize the disassembly of the spray disc 4 and the spray arm 3.

[0040] The spray disc 4 is provided with a through hole 43 which faces the positioning hole 331. The wall of the spray disc 4 which is provided with the spray holes 42 is provided with an opening 44. The connecting structure further comprises a positioning member 5, a first elastic member 52, a driving member 6 and a second elastic member 61.

[0041] The positioning member 5 is arranged in the spray disc 4. The positioning member 5 can move towards or away from the through hole 43, so that the positioning member 5 can partially pass through the through hole 43 or retract into the spray disc 4. The part of the positioning member 5 which can pass through the through hole 43 is the positioning part 51.

[0042] The first elastic member 52 acts on the positioning member 5, so that the positioning member 5 keeps the tendency of moving towards the direction of retracting into the spray disc 4. In this embodiment, the first elastic member 52 is a spring. One end of the spring abuts against the positioning member 5, and the other end abuts against the side wall of the spray disc 4.

[0043] The driving member 6 is used to drive the positioning member 5, so that the positioning part 51 moves towards the positioning hole 331. The driving member 6 can also release the driving of the positioning member 5.

[0044] In the embodiment, the driving member 6 is arranged in the spray disc 4 and is movable along the axis direction of the ring body 33.

The positioning member 5 is arranged beside the pressing rod 63. The pushing part 64 extends towards the positioning member 5.

[0045] The pushing part 64 is provided with a first inclined surface 55 extending towards the side wall where the perforation 43 is located along the direction of movement of the pushing part 64 towards the water outlet 32. The positioning member 5 is provided with a second inclined surface 62 extending towards the side wall where the perforation 43 is located along the direction of movement of the positioning member 5 towards the water outlet 32. When the driving member 6 moves in the direction away from the water outlet 32, the first inclined surface 55 and the second inclined surface 62 are in contact, and the positioning member 5 is pushed so that the positioning part 51 moves towards the positioning hole 331.

[0046] The second elastic member 61 acts on the pressing rod 63 of the driving member 6, so that the driving member 6 tends to move in the direction away from the water outlet 32. The second elastic member 61 is a spring, one end of which is in contact with the pressing rod 63, and the other end is in contact with the side wall of the spray disc 4.

[0047] The pushing part 64 is in contact with the inner wall of the spray disc 4. At this time, the driving member 6 moves in the direction away from the water outlet 32 to the limit position. The end of the pressing rod 63 of the driving member 6 is located in the opening 44. In this state, the driving member 6 is in contact with the positioning member 5, and the positioning part 51 is inserted into the positioning hole 331 through the perforation 43.

[0048] The end of the pressing rod 63 is located in the opening 44 to facilitate contact pressing. When the pressing rod 63 is pressed, it can move towards the water outlet 32 to a state where it is not in contact with the positioning member 5. At this time, the driving member 6 releases the driving of the positioning member 5.

[0049] When the driving member 6 is pressed, the driving member 6 moves in the direction towards the water outlet 32 and is not in contact with the positioning member 5. At this time, the driving member 6 releases the driving of the positioning member 5. The positioning member 5 moves under the action of the first elastic member 52, so that the positioning part 51 is retracted into the spray disc 4, thereby achieving the disassembly of the spray disc 4 and the spray arm 3. When the driving member 6 is not pressed, the driving member 6 moves in the direction away from the water outlet 32 under the action of the second elastic member 61, pushes the positioning member 5 so that the positioning part 51 moves towards the positioning hole 331 and is inserted into the positioning hole 331, thereby achieving the assembly of the spray arm 3 and the spray disc 4.

[0050] The pushing part 64 has at least two parts arranged circumferentially and spaced apart from each other along the pressing rod 63. Correspondingly, the positioning member 5, the perforation 43 and the positioning hole 331 also have at least two parts. In this way, the spray disc 4 and the spray arm 3 are connected at multiple points, and the connection is reliable. In the embodiment, the pushing part 64 has two parts.

[0051] The spray disc 4 comprises a first shell 45 and a second shell 46 capable of being connected, the first shell 45 and the second shell 46 jointly enclose a containing space containing the positioning member 5 and the driving member 6, the opening 44 is arranged on the first shell 45, and the perforation 43 is arranged on the second shell 46. The positioning member 5, the driving member 6 and the like can be arranged in the second shell 46 first, and then the first shell 45 and the second shell 46 are connected.

[0052] The water supply pipe 2 is further provided with a drain port 22 located above the water outlet 21, and an upper spray arm connected in communication with the drain port 22 is also connected at the drain port 22. The upper spray arm can adopt an existing structure to clean the upper bowl basket, and the spray arm 3 can clean the lower bowl basket; by disassembling and assembling the spray disc 4, the water spraying area at the spray arm 3 can be adjusted to adapt to the lift of the upper spray arm.

[0053] In the description of the utility model, it is understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, since the embodiments disclosed by the utility model can be arranged in different directions, so these orientation indicating terms are only as an illustration and should not be regarded as a limitation, for example, "upper", "lower" are not necessarily limited to the direction opposite or consistent with the direction of gravity.
