[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 4 As shown, the airflow homogenization module of this embodiment includes: a coupling seat 1 and a homogenization module 2. The coupling seat 1 is provided with an air inlet 11. The homogenization module 2 is installed in the coupling seat 1. There is a first annular air passage 12 between the homogenization module 2 and the coupling seat 1. The first annular air passage 12 is connected to the air inlet 11. A protection module 100 is installed in the homogenization module 2. There is a second annular air passage 21 between the homogenization module 2 and the protection module 100. The second annular air passage 21 is connected to the first annular air passage 12. Gas enters the first annular air passage 12 and the second annular air passage 21 sequentially from the air inlet 11. The gas reaches a homogenized state in the second annular air passage 21.

[0033] In other words, the protective gas is introduced through the air inlet 11 and gradually fills the first annular air passage 12 for initial homogenization. Then, the protective gas enters the second annular air passage 21 from the first annular air passage 12 for full homogenization, and finally enters the protection module 100. This embodiment, by combining the first annular air passage 12 and the second annular air passage 21, can achieve full homogenization of the protective gas, enabling the protective gas to form a stable protective gas field around the coupled energy beam, thereby improving the stability and shaping effect of the coupled energy beam.

[0034] In this embodiment, the homogenization module 2 has multiple first through holes 22, which are evenly distributed around the circumference of the homogenization module 2. The first through holes 22 are used to connect the second annular air passage 21 and the first annular air passage 12. For example, there are 10 first through holes 22. After the protective gas enters the first annular air passage 12, it can enter the second annular air passage 21 (i.e., the airflow homogenization chamber) through the multiple first through holes 22. The multiple first through holes 22 are evenly distributed around the circumference of the homogenization module 2, which can homogenize the pressure distribution when the protective gas enters the airflow homogenization chamber, so as not to cause a large pressure impact on one side. The protection module 100 has a protection air passage 101, which is connected to the second annular air passage 21. The protection module 100 has multiple second through holes 103, which are evenly distributed around the circumference of the protection module 100. The second through holes 103 are used to connect the second annular air passage 21 and the protection air passage 101. In other words, the gas in the second annular airway 21 can enter the protective airway 101 through the second through hole 103. When the coupled energy beam passes through the protective airway 101, the protective gas can form a protective gas field around the coupled energy beam, enveloping the coupled energy beam and shaping the surface of the coupled energy beam to improve the stability of the coupled energy beam and increase the water jet.

[0035] In this embodiment, the first through hole 22 and the second through hole 103 are offset in the height direction. Both the first through hole 22 and the second through hole 103 are horizontally arranged, with the first through hole 22 at the bottom and the second through hole 103 at the top. If the first through hole 22 and the second through hole 103 are arranged on the same horizontal line, when the airflow enters the second annular air passage 21 through the first through hole 22, it will directly rush into the protective air passage 101 through the second through hole 103, impacting the coupled energy beam and affecting its stability. In this embodiment, the first through hole 22 and the second through hole 103 are offset to prevent gas from flowing directly into the second through hole 103 after passing through the first through hole 22.

[0036] For example, the first annular air passage 12 is an annular groove formed on the coupling seat 1 or the homogenization module 2. For example, the second annular air passage 21 is an annular groove formed on the homogenization module 2 or the protection module 100.

[0037] In this embodiment, the protective airway 101 includes a first channel 1011 and a second channel 1012, wherein the first channel 1011 and the second channel 1012 are connected, and the first channel 1011 is connected to a second through hole 103. The diameter of the second channel 1012 is smaller than the diameter of the first channel 1011. The coupled energy beam passes sequentially through the first channel 1011 and the second channel 1012 along the axial direction of the protective airway 101. When the protective gas enters the first channel 1011, a protective gas field is formed around the coupled energy beam. Because the diameter of the second channel 1012 is smaller than the diameter of the first channel 1011, the gas velocity increases when the gas enters the second channel 1012 from the first channel 1011, which helps to extend the effective length of the water jet.

[0038] In this embodiment, the outer diameter of the homogenizing module 2 matches the inner diameter of the coupling seat 1. This minimizes the assembly gap between the homogenizing module 2 and the coupling seat 1. Since gas may leak from the assembly gap, affecting the airflow homogenization effect, sealing is required. A first sealing element 3 and a second sealing element 4 are provided between the homogenizing module 2 and the coupling seat 1, respectively sealing the upper and lower sides of the first annular air passage 12. A third sealing element 5 and a fourth sealing element 6 are provided between the homogenizing module 2 and the protection module 100, respectively sealing the upper and lower sides of the second annular air passage 21. For example, a first annular groove 23 and a second annular groove 24 are formed on the outer wall of the homogenizing module 2. The first annular groove 23 is used to install the first sealing element 3, and the second annular groove 24 is used to install the second sealing element 4, respectively sealing the upper and lower sides of the first annular air passage 12. A third annular groove 25 is formed on the inner wall of the homogenization module 2, and a fourth annular groove 102 is formed on the outer wall of the protection module 100. The third annular groove 25 is used to install the third sealing element 5, and the fourth annular groove 102 is used to install the fourth sealing element 6. The third sealing element 5 and the fourth sealing element 6 respectively seal the upper and lower sides of the second annular air passage 21. That is to say, in this embodiment, by setting multiple sealing elements, the first annular air passage 12 and the second annular air passage 21 can be sealed to prevent gas from leaking from the assembly gap.

[0039] The specific process of airflow homogenization is as follows: Gas enters the first annular air passage 12 through the air inlet 11. After filling the first annular air passage 12, the gas enters the second annular air passage 21 through the first through-hole 22. After the gas reaches a homogenized state in the second annular air passage 21, it enters the protective air passage 101 through the second through-hole 103. At this time, the gas can form a stable protective air field around the water column, making the water column more stable during the spraying process. Since the diameter of the first channel 1011 is larger than the diameter of the second channel 1012, when the protective air field and the water column enter the second channel 1012 together from the first channel 1011, the gas flow rate can be increased, effectively extending the length of the water column.

[0040] In summary, the airflow homogenization module of this utility model, through the combination of the first annular airway 12 and the second annular airway 21, can achieve full homogenization of the protective gas, enabling the protective gas to form a stable protective gas field around the coupled energy beam, thereby improving the stability and shaping effect of the coupled energy beam.
