[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] like Figures 1 to 2 As shown, the water flow homogenization module of this embodiment includes: a coupling seat 1, a homogenization module 2, and a water flow homogenization cavity 3. The coupling seat 1 has a first receiving cavity 11, and a light-transmitting element 200 is installed in the first receiving cavity 11. The homogenization module 2 is installed in the first receiving cavity 11 and spaced apart from the light-transmitting element 200. The water flow homogenization cavity 3 is located between the light-transmitting element 200 and the homogenization module 2. The water flow homogenization cavity 3 includes a peripheral convergence cavity 31 and a smoothing cavity 32 located in the middle area. The water flow homogenization cavity 3 of this embodiment has a convergence cavity 31 and a smoothing cavity 32. When the high-pressure water flow enters the convergence cavity 31, the convergence cavity 31 can suppress strong turbulence, making the high-pressure water flow gradually become smooth. Then, after further smoothing by the smoothing cavity, the water column flowing out of the outlet of the water flow homogenization cavity 3 has better stability.
[0033] In this embodiment, as Figure 3 As shown, the width D1 of the gathering cavity 31 gradually decreases from the edge towards the smoothing cavity 32, while the width D2 of the smoothing cavity 32 is constant everywhere. The upper surface of the water flow homogenizing cavity 3 is a plane, and the lower surface of the water flow homogenizing cavity 3 includes an outer arc surface 33 and a middle plane 34. The arc surface 33 and the plane 34 have a smooth transition. The arc surface 33 corresponds to the gathering cavity 31, and the plane 34 corresponds to the smoothing cavity 32. Of course, in other embodiments, such as... Figure 4 As shown, the water flow homogenization cavity 3 can have an upper end surface including an outer arc surface 33 and a middle plane 34, and the lower end surface of the water flow homogenization cavity 3 is a plane. Alternatively, as... Figure 5 As shown, the upper and lower surfaces of the water flow homogenization cavity 3 each include an outer arc surface 33 and a middle plane 34. The arc surface 33 can also be replaced by an inclined surface (referring to an inclined plane).
[0034] As the high-pressure water flows from the edge of the water flow homogenization chamber 3 to the center, the impact force of the high-pressure water flow is relatively large. The edge width of the water flow homogenization chamber 3 is set to be relatively large, which can play a certain buffering role and suppress strong turbulence. Then the water flow enters the narrower middle part, which can further reduce the fluctuation of the water flow, improve the stability of the water flow, and achieve the homogenization effect.
[0035] like Figure 7 and Figure 8 As shown, in this embodiment, the water flow homogenization module further includes: an annular water channel 23 and multiple water distribution grooves 24. The annular water channel 23 is connected to the water inlet hole 12 opened on the coupling seat 1, and the annular water channel 23 is connected to the gathering cavity 31 through the multiple water distribution grooves 24. The annular water channel 23 is the first annular cavity formed by the homogenization module 2 and the coupling seat 1, and the first annular cavity is connected to the water inlet hole 12; the multiple water distribution grooves 24 are arranged around the axis of the homogenization module 2 and connect the annular water channel 23 to the gathering cavity 31. For example, an annular water channel 23 is opened on the outer wall of the homogenization module 2, and a water inlet hole 12 is opened on the coupling seat 1. The water inlet hole 12 is connected to the annular water channel 23, and the annular water channel 23 is connected to the water flow homogenization cavity 3. That is to say, the high-pressure water flow enters the annular water channel 23 through the water inlet hole 12. After the high-pressure water flow fills the annular water channel 23, it can enter from the edge of the water flow homogenization cavity 3 and gradually fill the entire water flow homogenization cavity 3.
[0036] Multiple water distribution channels 24 are formed on the outer edge of the homogenization module 2 or the inner wall of the coupling seat 1. These channels 24 are evenly distributed around the circumference of the homogenization module 2, and an annular water channel 23 connects to the water flow homogenization cavity 3 via the channels 24. The channels 24 are vertically continuous, and the number of channels 24 is ≥3; in this embodiment, for example, there are 10 channels. The annular water channel 23 is positioned lower than the water flow homogenization cavity 3, and the water flow from the annular water channel 23 flows upward into the water flow homogenization cavity 3 through the multiple channels 24. When the high-pressure water flow fills the annular water channel 23, it can flow upward through the channels 24 and enter the water flow homogenization cavity 3. The channels 24 are evenly distributed around the circumference of the homogenization module 2. When the high-pressure water flow enters the water flow homogenization cavity 3 through the channels 24, it can homogenize the impact force on the water flow homogenization cavity 3, thus contributing to water flow homogenization.
[0037] like Figure 6 and Figure 9As shown, it should be noted that the homogenization module 2 is provided with a first installation cavity 25 for installing the nozzle 100. The nozzle 100 is provided with a coupling hole 101, and the coupling hole 101 communicates with the gentle cavity 32. The upper end surface of the nozzle 100 is flush with the plane 33. The nozzle 100 includes: a first installation part 102, a second installation part 103, and a third installation part 104. The first installation part 102 is located above the second installation part 103, and the third installation part 104 is located below the second installation part 103. The diameters of the first installation part 102 and the third installation part 104 are both smaller than the diameter of the second installation part 103. The nozzle 100 is an integrally formed part. The shape of the first installation cavity 25 matches the "convex" shape formed by the first installation part 102 and the second installation part 103. The coupling hole 101 is located in the first installation part 102. A connection channel 105 is provided in the second installation part 103, and a frustum-shaped cavity 106 is provided in the third installation part 104. The coupling hole 101, the connection channel 105, and the frustum-shaped cavity 106 communicate with each other. The water flow homogenized by the water flow homogenization cavity 3 can enter the coupling hole 101, and in the coupling hole 101, the laser beam and the water column can be coupled and then ejected.
[0038] In this embodiment, a first seal 4 is provided between the homogenization module 2 and the coupling seat 1, a second seal 5 is provided between the homogenization module 2 and the nozzle 100, and a third seal 6 is provided between the light-transmitting member 200 and the coupling seat 1. For example, a first annular groove 26 is provided on the side wall of the first installation cavity 25, and the first seal 4 is installed in the first annular groove 26. A second annular groove 27 is provided on the outer side wall of the homogenization module 2, and the second seal 5 is installed in the second annular groove 27. The coupling seat 1 further has a second accommodation cavity 13, and a light-transmitting member 200 (such as a light-transmitting glass) is installed in the second accommodation cavity 13. A third annular groove 14 is provided on the side wall of the second accommodation cavity 13, and the third seal 6 is installed in the third annular groove 14. Since the water flow homogenization cavity 3 is a space formed by surrounding multiple components, there will be assembly gaps between the components, and there is a risk of water leakage when water enters. Therefore, in this embodiment, seals are provided at multiple places to ensure that the water flow homogenization cavity 3 has a unique inlet and outlet. For example, the first seal 4 is used to seal the assembly gap between the inner side wall of the homogenization module 2 and the nozzle 100. The second seal 5 is used to seal the assembly gap between the outer side wall of the homogenization module 2 and the side wall of the first accommodation cavity 11. The third seal 6 is used to seal the assembly gap between the light-transmitting member 200 and the side wall of the second accommodation cavity 13. Thus, a full-range seal of the water flow homogenization cavity 3 can be achieved.
[0039] The specific process of water flow homogenization is as follows: High-pressure water flows into the annular water channel 23 through the inlet hole 12. After filling the annular water channel 23, the high-pressure water flows upward through multiple water distribution grooves 24 and enters the converging chamber 31 and the smoothing chamber 32 in sequence. When the high-pressure water flows in through the inlet hole 12, it is relatively turbulent. After filling the annular water channel 23, under the action of squeezing force, the water flows upward through several water distribution grooves 24 and enters the converging chamber 31. Due to the structural characteristics of the converging chamber 31, the turbulent water flow can be suppressed by the gradual converging action of the converging chamber 31, so that the water flow gradually becomes smooth and enters the smoothing chamber 32. After entering the smoothing chamber 32, the water flow can be further stabilized under the squeezing action of the smoothing chamber 32. The water flow as a whole forms a uniform pressure distribution with the coupling hole 101 as the center in the smoothing chamber 32.
[0040] In summary, the water flow homogenization module of this utility model, by improving the structure of the water flow homogenization cavity 3, can suppress strong turbulence and improve the water flow homogenization effect; thereby enabling the water column and the laser beam to achieve a better coupling state.
