Example Embodiment
[0036] Example 1:
[0037] An integral carbide pulse nozzle such as figure 1 As shown, it includes a pulse nozzle main body 10, the pulse nozzle main body 10 is a cylindrical structure, the pulse nozzle main body 10 is provided with a cone-shaped inner resonant cavity 20, a nozzle outlet 30 is arranged above the inner resonant cavity 20, and the inner resonant cavity A guide channel 40 is provided below the 20 , the inner resonant cavity 20 and the nozzle outlet 30 and the guide channel 40 form a hollow cavity with two large ends and a small one in the middle, and an upper collision surface 201 is provided at the connection between the inner resonant cavity 20 and the nozzle outlet 30 . , a lower collision surface 202 is provided at the junction of the inner resonant cavity 20 and the diversion channel 40 .
[0038] The appearance and shape of the pulse nozzle and the internal cavity structure are relatively complex, and it is extremely difficult to produce an integral cement...
Example Embodiment
[0039] Example 2:
[0040] The difference between this embodiment and Embodiment 1 is that the angle α between the upper collision surface and the inner resonator cavity wall is 60°, the included angle β between the lower collision surface and the inner resonator cavity wall is 120°, and the upper collision surface is 120°. and the lower collision surface are all tapered structures.
Example Embodiment
[0041] Example 3:
[0042] The difference between this embodiment and Embodiment 1 and Embodiment 2 is that the diversion channel is a conical structure, a curved structure, a streamlined structure, an elliptical structure, a circular arc structure, a double circular arc structure and an equal variable speed shape. one of the structures.
