[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] This application discloses a spray assembly, referring to... Figure 1 and Figure 2 It includes a nozzle 1 and a water inlet 3. The nozzle 1 is provided with a spray port 110 and multiple blades 2. The blades 2 have an inner end 21 near the center of the nozzle 1 and an outer end 22 away from the center of the nozzle 1.

[0025] The water inlet 3 has a water inlet cavity 30, the nozzle 1 is rotatably connected to the water inlet 3, the spray port 110 is connected to the water inlet cavity 30, the water inlet cavity 30 is provided with a water guide channel 31, the water guide channel 31 has a guide inlet 310 and a guide outlet 311, the guide outlet 311 guides the liquid flowing in from the guide inlet 310 to impact the outer end 22 of at least one blade 2 and drive the nozzle 1 to rotate.

[0026] By utilizing the impact force of water flow on the blades 2, the nozzle 1 can rotate around an axis while spraying water, thereby increasing the cleaning coverage area of ​​the items to be washed and achieving a better cleaning effect.

[0027] Reference Figure 2 and Figure 3 In this embodiment, the nozzle 1 is provided with a spray cavity 10 inside, and the nozzle 1 is provided with an inlet 120 that communicates with the spray cavity 10. The spray port 110 and the spray cavity 10 are connected, and the spray cavity 10 is connected with the water inlet cavity 30 through the inlet 120.

[0028] The nozzle 1 includes an outer portion 11 and an inner portion 12, which together form a spray cavity 10. The outer portion 11 is provided with a spray port 110, and the inner portion 12 is provided with an inlet 120. The portion of the outer portion 11 with the spray port 110 extends beyond the outer side of the water inlet 3. Figure 4 The diameter of the outer part 11 is smaller than the diameter of the inner part 12, and a step is formed between the outer part 11 and the inner part 12. The water inlet 3 is provided with a mounting hole 300. The diameter of the inner part 12 is larger than the diameter of the mounting hole 300, and the diameter of the outer part 11 is close to the diameter of the mounting hole 300. When the nozzle 1 is placed in the mounting hole 300, the step limits the nozzle 1.

[0029] The blade 2 is connected to the inner part 12 and located in the water inlet chamber 30. The blade 2 has multiple blades and is evenly distributed along the circumference of the nozzle 1. The line connecting the outer end 22 and the inner end 21 of the blade 2 is set at an angle to the radial direction of the nozzle 1.

[0030] The blade 2 is fixed or integrally formed on the end face of the inner side 12 that is away from the outer side 11.

[0031] In other embodiments, the nozzle 1 has no spray cavity 10, a part of the nozzle 1 extends out of the water inlet cavity 30, and the other part of the nozzle 1 is located in the water inlet cavity 30. The blade 2 is connected to the part of the nozzle 1 located in the water inlet cavity 30, and the water flow in the water inlet cavity 30 directly impacts the blade 2 and drives the nozzle 1 to rotate.

[0032] In other embodiments, the blades 2 can also be disposed in the spray cavity 10. When water flows into the spray cavity 10 from the inlet 120, it can impact the blades 2 and drive the nozzle 1 to rotate.

[0033] Reference Figure 4 To ensure the nozzle 1 remains stable during rotation, in this embodiment, the inner side 12 has a protrusion 41 located away from the center of the outer side 11. The water inlet 3 has a groove 42 located on the inner wall of the water inlet cavity 30, which is rotatably connected to the protrusion 41. At least a portion of the protrusion 41 extends into the groove 42, and the outer wall of the protrusion 41 and the inner wall of the groove 42 are in clearance fit. Multiple blades 2 are arranged around the protrusion 41 in the circumference of the inner side 12.

[0034] In other embodiments, the water inlet 3 is provided with a protrusion 41, and the nozzle 1 is provided with a groove 42.

[0035] In other embodiments, the protrusion 41 may be annular, and the groove 42 may also be annular accordingly.

[0036] In other embodiments, the protrusion 41 can be provided at the part of the nozzle 1 that extends out of the water inlet cavity 30, and the groove 42 can be provided on the outer side wall of the water inlet 3, as long as the protrusion 41 and the groove 42 can be adapted to achieve rotational limiting and guiding.

[0037] Reference Figure 2 and Figure 3 To improve the cleaning effect, at least a portion of the nozzle 1 extending outside the water inlet 3 is provided with an air inlet 130 communicating with the spray cavity 10. One or more air inlets 130 may be provided. In this embodiment, the air inlet 130 is located on the circumferential sidewall of the outer portion 11.

[0038] The outer side 11 has a jet section 13 protruding away from the inner side 12 on the surface extending from the water inlet cavity 30. The jet section 13 has a jet port 110. The inner wall of the inner side 12 has an inlet section 14 protruding toward the jet section 13. The inlet section 14 has an inlet port 120. At least a portion of the inlet section 14 extends into the inner cavity of the jet section 13. There is a gap between the inlet section 14 and the jet section 13. This gap forms part of the jet cavity 10 and communicates with the air inlet 130.

[0039] At least two spray nozzles 110 are provided, and each spray nozzle 110 is distributed at intervals along the circumferential direction of the nozzle 1 rotation. The water jets sprayed from the spray nozzles 110 can assist in driving the nozzle 1 to rotate. The plane where the spray nozzles 110 are located is inclined to the side surface of the outer part 11 that is away from the inner part 12.

[0040] Reference Figure 1 The water inlet 3 is provided with a water guide rib 5 inside the water inlet cavity 30. The water guide rib 5 is located between the front inner wall of the water inlet 3 where the nozzle 1 is located and the rear inner wall opposite to the front inner wall. The water guide rib 5 and part of the inner wall of the water inlet 3 form a water guide channel 31. The opening size of the guide outlet 311 is smaller than the opening size of the guide inlet 310. The guide outlet 311 is close to the outer edge of the part of the nozzle 1 inside the water inlet cavity 30, so that the water flow sprayed from the guide outlet 311 can impact the outer end 22 of the blade 2, thereby ensuring that the water flow concentrates to impact the blade 2, realizes efficient energy conversion, and ensures rotational reliability.

[0041] The water inlet 3 has a flushing inlet for connecting the water inlet chamber 30 and the outside. High-pressure water can enter the water inlet chamber 30 from the flushing inlet. Most of the high-pressure water enters the water guide channel 31 from the guide inlet 310 and is ejected from the guide outlet 311. Some of the high-pressure water can also directly enter the jet cavity 10 from the inlet 120.

[0042] This application also discloses a cleaning device, including a spray assembly described in the above embodiments. The cleaning device can be a dishwasher, a fruit and vegetable cleaning machine, etc.

[0043] Reference Figure 4 The cleaning equipment also includes a basket 6 for placing items to be washed, a water inlet 3 integrally formed into the basket 6, and a nozzle 1 with a spray port 110 located on the inner side of the basket 6. The inlet of the water inlet chamber 30 can be connected to an external high-pressure water flow. Multiple sets of spray assemblies can be arranged along the circumference or bottom surface of the basket 6.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
