[0033] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0034] Unless otherwise specified or defined, the "first, second..." used in this article is only used to distinguish names and does not represent a specific quantity or order.

[0035] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0037] To achieve a more even distribution of the water flow sprayed by the diffuser, the present invention divides the water flow impacting downward onto the diffuser into different water distribution zones through an arc-shaped water divider plate. The water flows to a first zone and a second zone between the water divider plates. Water distribution holes are provided in the first zone, allowing spray water to fall around the center of the diffuser, achieving close-range spraying. The second zone is divided into a first water flow channel, a second water flow channel, and a third water flow channel by a guide wall. The outlets of the first water flow channel, the second water flow channel, and the third water flow channel are arranged at different distances from the center, so that spray water can fall in annular areas below the nozzle at different distances from the center. Compared to the water distribution holes, this achieves even water flow distribution at a longer distance. The water distribution holes and the water outlets together provide a more even distribution of water flow below the diffuser.

[0038] refer to Figure 1 and Figure 2 The diffuser 100 of this embodiment is a disc-shaped body with a base plate 10 at the bottom and a sleeve 20 at the center. The sleeve 20 can be sleeved on the central axis of the nozzle to form a rotation center. Under the impact of the water flow, the diffuser 100 can rotate around the central axis of the nozzle. Six water diversion plates 30 are connected to the side walls of the sleeve 20 and are distributed circumferentially on the base plate 10. The water diversion plates 30 are arc-shaped and extend to the outside of the diffuser 100. The water diversion plates 30 divide the water flow that impacts the diffuser 100 downward into different parts, and when the water flow impacts the arc-shaped water diversion plates 30, a circumferential tangential force is generated, which drives the diffuser 100 to rotate. It should be noted that there is no limit to the number of water diversion plates 30 and they can be designed accordingly according to the size of the diffuser 100.

[0039] A radially inner first area 40 and a radially outer second area 50 are formed between each two water diversion plates 30 . The first area 40 is adjacent to the sleeve 20 , and the second area 50 is away from the sleeve 20 . The area of ​​the first area 40 is smaller than that of the second area 50 .

[0040] A water distribution hole 41 is provided on the bottom plate 10 of the first zone 40, through which the area below the center of the diffuser 100 is sprayed. In this embodiment, to enhance the spraying effect at close range, two types of water distribution holes 41 are provided in the first zone 40, namely, an inner water distribution hole 411 and an outer water distribution hole 412. The inner water distribution holes 411 and the outer water distribution holes 412 are arranged alternately in the six first zones 40. That is, if an inner water distribution hole 411 is provided in a first zone 40, an outer water distribution hole 412 is provided in the next adjacent first zone 40. The inner water distribution hole 411 is located adjacent to the connection between the water distribution plate 30 and the sleeve 20, close to the center of rotation, and has a trapezoidal shape. The outer water distribution hole 412 is located substantially at the center of the outer periphery of the first zone 40, adjacent to the second zone 50, away from the center of rotation, and has a rectangular shape. Preferably, the size (e.g., area) of the outer water distribution hole 412 is larger than that of the inner water distribution hole 411. The spraying effect of the inner water holes 411 is the annular zone closest to the center of the water diffuser 100 , and the spraying effect of the outer water holes 412 is another annular zone outside the annular zone.

[0041] like Figure 3 As shown, in order to increase the spraying area of ​​the water distribution hole 41, the first side wall 413 and the second side wall 414 of the water distribution hole 41 in the radial direction are both set to be inclined downward, and the inclination angle of the first side wall 413 is preferably the same as the inclination angle of the second side wall 414. The two inclined side walls are similar to forming an inclined pipe, so that the water flow is sprayed farther.

[0042] like Figure 1 and Figure 4 As shown, two arc-shaped guide walls 51 are provided in the middle of the second zone 50 formed between the two water diversion plates 30. The arc direction of the guide walls 51 is the same as that of the water diversion plates 30, and the guide walls 51 are shorter in radial direction than the water diversion plates 30. The two guide walls 51 divide the second zone 50 into three water flow channels: a first water flow channel 52, a second water flow channel 53, and a third water flow channel 54. The outlets of the three water flow channels are at different distances from the center of the bottom plate 10. Among them, the outlet 521 of the first water flow channel 52 is closest to the center of the bottom plate 10 and is close to the starting point of the first water flow channel 52. The specific location of the outlet 531 of the second water flow channel 53 is not limited, and its distance from the center of the bottom plate 10 is greater than the distance between the outlet 521 of the first water flow channel 52 and the center of the bottom plate 10. The outlet 541 of the third water flow channel 54 is farthest from the center of the bottom plate 10 and is located at the edge of the third water flow channel 54. By setting the positions of the water outlets (521, 531, 541) at different distances, the annular areas at different distances from the center can all have spray water falling, and the water flow is evenly distributed. Moreover, in this embodiment, at least two of the first water flow channel 52, the second water flow channel 53, and the third water flow channel 54 are at different distances relative to the rotation center, and the order of the water flow in different water flow channels can be adjusted by setting different distances.

[0043] refer to Figure 1 In this embodiment, the six water distribution plates 30 form six second areas 50. The arrangement order of the first water flow channel 52, the second water flow channel 53, and the third water flow channel 54 in each two axisymmetric second areas 50 is the same. Figure 1 Starting from the starting point S, and going counterclockwise, the arrangement order of the three water flow channels in the six second zones 50 is as follows: the first second zone 50 is the first water flow channel 52, the second water flow channel 53, and the third water flow channel 54; the second second zone 50 is the second water flow channel 53, the third water flow channel 54, and the first water flow channel 52; the third second zone 50 is the third water flow channel 54, the second water flow channel 53, and the first water flow channel 52; the fourth second zone 50 is the first water flow channel 52, the second water flow channel 53, and the third water flow channel 54; the fifth second zone 50 is the second water flow channel 53, the third water flow channel 54, and the first water flow channel 52; and the sixth second zone 50 is the third water flow channel 54, the second water flow channel 53, and the first water flow channel 52. By symmetrically arranging the three water flow channels, the smoothness and efficiency of the water diffuser's rotation can be improved. Furthermore, the arrangement order of the first water channel 52, the second water channel 53, and the third water channel 54 in two adjacent second zones 50 is different, which can effectively improve the efficiency of water spraying. In this embodiment, when the third water channel 54 is located between the first water channel 52 and the second water channel 53, the outlet 521 of the first water channel 52 is close to the starting point of the first water channel 52, and the outlet 531 of the second water channel 53 is close to the starting point of the second water channel 53. In other cases, the outlet 521 of the first water channel 52 is close to the starting point of the first water channel 52, and the outlet 531 of the second water channel 53 is close to the end point of the second water channel 53. The staggered arrangement of the water outlets improves the uniformity of the spraying.

[0044] To ensure uniform water distribution, the outer edges of all inner water holes 411 in this embodiment (the radial direction from the center of the diffuser pointing outward is used as the inner and outer measurement standard in this article) rotate along a circle. The first sidewall (i.e., the inner sidewall) of the outer water hole 412 is tangent to this circle. Similarly, the bottom edge of the outlet 521 of the first water channel 52 is tangent to the circle formed by the outer edges of all outer water holes 412. Furthermore, the outlets of all first and second water channels 52, 53 in three adjacent second zones 50 are at different distances from the center of the base plate 10. This ensures that no dry gaps are created during water spraying.

[0045] In order to adjust the spraying angles of the first water flow channel 52 and the second water flow channel 53, baffles 55 are provided above the water outlet 521 of the first water flow channel 52 and the water outlet 531 of the second water flow channel 53. The arrangement order of the first water flow channel 52 and the second water flow channel 53 in the second zone 50 is different, and the two side walls forming the first water flow channel 52 and the second water flow channel 53 are also different. They may both be guide walls 51, or they may be a guide wall 51 and a water diversion plate 30. Therefore, the two ends of the baffle 55 may be connected to two guide walls 51, or they may be connected to a water diversion plate 30 and a guide wall 51. The two side walls, the bottom plate 10 and the baffle 55 surround the water outlet 521 of the first water flow channel 52 and the water outlet 531 of the second water flow channel 53, as shown in FIG. Figure 5 As shown, the water outlet 521 of the first water flow channel 52 and the water outlet 531 of the second water flow channel 53 are both square.

[0046] refer to Figure 1 、 Figure 4 and Figure 6 Each baffle 55 includes an upper end surface 551 located radially inward and upward, and a lower end surface 552 located radially outward and inclined downward. A guide surface 553 is provided radially inward and downward on the lower side of the baffle 55. The guide surface 553 is also inclined downward, with the upper end surface 551 and the guide surface 553 forming a pointed tip at the upper end of the baffle 55. The inclined guide surface 553 adjusts the spray angle. Because the outlet 521 of the first water channel 52 is closer to the center of the bottom plate 10 than the outlet 531 of the second water channel 53, in order to ensure that the water sprayed from the outlet 521 of the first water channel 52 and the water sprayed from the outlet 531 of the second water channel 53 form different spray areas, in this embodiment, the guide surface 553 in the baffle 55 of the first water channel 52 has a greater inclination angle than the guide surface 553 in the baffle 55 of the second water channel 53.

[0047] In some embodiments, the width of the water outlet 521 of the first water flow channel 52 is different from the width of the water outlet 531 of the second water flow channel 53, and the width of the water outlet is used to control the spraying area of ​​the water outlet. It is easy to understand that the inclined second plate in the baffle and the width of the water outlet can be set at the same time.

[0048] In this embodiment, in order to make the water flow more efficiently to the water outlet 521 of the first water flow channel 52 and the water outlet 531 of the second water flow channel 53. A guide block 56 is provided on the side wall (guide wall 51 or water diversion plate 30) of the first water flow channel 52, and a guide block 56 is also provided on the side wall (guide wall 51 or water diversion plate 30) of the second water flow channel 53. The direction of the water flow is controlled by the guide block 56, and no water flow detour area is generated. Preferably, the water outlet 521 of the first water flow channel 52 and the water outlet 531 of the second water flow channel 53 are both provided with a guide block 56, but it can also be provided only at the water outlet 521 of the first water flow channel 52 or the water outlet 531 of the second water flow channel 53 as needed, and a guide block 56 can also be provided on the third water flow channel 54.

[0049] Specifically, the first water flow channel 52 and the second water flow channel 53 are located at different positions in the second zone 50, and the first end of the guide block 56 is connected to either the water diversion plate 30 or the guide wall 51. The guide block 56 is similar to a triangular block. When connected to the water diversion plate 30, the second end of the guide block 56 extends radially outward, gradually increasing in width until it intersects with the upper end surface 551, narrowing the width of the water flow channel at that location. When the first end of the guide block 56 is connected to the guide wall 51, the second end of the guide block 56 extends radially outward, gradually increasing in width until it intersects with the upper end surface 551, narrowing the width of the water flow channel at that location.

[0050] To control the spray range of the third water channel 54, an extension wall 57 is provided on the outer curved surface of the guide wall 51 or the outer curved surface of the water divider 30 that forms the third water channel 54. The free end of the extension wall 57 extends radially outward, and the radial outer end of the extension wall 57 is separated from the side wall of the adjacent first water channel 52 or second water channel 53. The extension wall 57 forms a V-shape with the side wall of the adjacent first water channel 52 or second water channel 53. The extension wall 57 is used to adjust the width of the water outlet 541 of the third water channel 54, making the third water channel 54 wider in the middle and narrower at both ends. Obviously, the first water channel 52 and the second water channel 53 can also be configured to have a shape that is wider in the middle and narrower at both ends, that is, the radial inner and radial outer sections are narrower than the radial middle section.

[0051] The center of the bottom plate 10 of the water diffuser 100 in this embodiment is raised upwards, and accordingly, the surface formed by the top of the water diversion plate 30 is also raised upwards, so that the water diffuser 100 rotates more efficiently and smoothly.

[0052] In summary, this embodiment uses the water distribution holes to allow spray water to fall around the center of the sprinkler, achieving close-range spraying. The guide wall separates the sprinkler into a first water channel, a second water channel, and a third water channel. Furthermore, the outlets of the first, second, and third water channels are positioned at different distances from the center, allowing spray water to fall in annular areas below the sprinkler head at varying distances from the center. This achieves uniform water flow distribution over longer distances compared to the water distribution holes. Thus, the water distribution holes and outlets together provide a more even distribution of water flow below the sprinkler.

[0053] Based on any one of the above-mentioned water diffusers, the utility model also provides a countercurrent cooling tower nozzle, which includes any one of the above-mentioned water diffusers.

[0054] The above embodiments are not exhaustive of the present invention, and there may be many other embodiments not listed. Any replacements and improvements made without violating the concept of the present invention are within the scope of protection of the present invention.
