For the convenience of the description, the central idea expressed by the present invention in the column of the above summary of the invention is expressed by the specific embodiments. Various items in the embodiments are depicted in terms of ratios, dimensions, amounts of deformation, or displacements that are suitable for illustration, and are not drawn to the proportions of actual elements, as set forth above.

As shown in the first, second and third figures, the joint device 10 of the present invention comprises an annular body 11 having an inner wall 12, an outer wall 13, and a first end connected to the inner wall 12 and the outer wall 13 An end face 14 and a second end face 15. The inner wall 12 encircles an inner passage 16 of the annular body 11. An annular space 17 is defined between the inner wall 12 and the outer wall 13.

The first end surface 14 of the annular body 11 is provided with a plurality of spray holes 19, each of which is connected to the annular space 17. The first end surface 14 and the second end surface 15 respectively extend a first connecting portion 21 and a second connecting portion 22, and the first connecting portion 21 and the second connecting portion 22 each have an external thread for connecting the conveying tube Road 31. The first end surface 14 and the second end surface 15 respectively have a first inclined guiding surface 23 and a second inclined guiding surface 24, and the inclined directions of the first oblique guiding surface 23 and the second oblique guiding surface 24 are from the first The connecting portion 21 and the second connecting portion 22 are inclined in the direction of the inner wall 12. The outer wall 13 may have a circular or polygonal cross section.

As shown in the fourth figure, the connecting hole 18 is connected to an external pipe 30. The external pipe 30 is connected to a fluid source (not shown). The fluid may be water or air, and may be pressurized or unpressurized. fluid. In the fourth figure the fluid is shown by a hollow arrow. The fluid is injected into the annular space 17, and the flow velocity of the fluid is increased based on the cross-sectional area of the jet hole 19, the flow velocity of the fluid is increased, and the pressure of the internal passage 16 is lowered and the fluid is sprayed along the fluid.
