[0020] Combined with appendix Figure 1 and attached Figure 2 As shown, a built-in direct-blowing air-cooled ultrasonic transducer includes a housing 1, a blower pipe 2, a connecting plate 3, and a transducer body 4. The transducer body 4 is installed at the front opening of the housing 1, and the connecting plate 3 is installed at the rear opening of the housing 1. Two or more blower pipes 2 are connected to the connecting plate 3. The front end of the blower pipe 2 is provided with an elbow 5, and the air outlet of the elbow 5 faces the transducer body 4. The two blower pipes 2 are symmetrically distributed on both sides of the transducer body 4, and the blower pipes 2 are connected to a fan.

[0021] The airflow generated by the fan passes through the elbow 5 at the front end of the air duct 2 and blows directly onto the transducer body 4 near it, maximizing the concentration of airflow for cooling. Two symmetrical air ducts 2 blow air onto opposite sides of the transducer body 4, further improving cooling efficiency.

[0022] The outer wall of the blower tube 2 is threaded, and the connecting plate 3 is threaded. The threaded hole of the connecting plate 3 is threadedly connected to the blower tube 2. The threaded connection allows for quick assembly and disassembly of the blower tube 2 and the connecting plate 3.

[0023] The connecting plate 3 has an annular groove along its edge, and a sealing ring is installed inside the annular groove. The sealing ring fits against the inner wall of the housing 1. In addition to improving the sealing performance, the sealing ring also allows for an interference fit between the connecting plate 3 and the rear opening of the housing 1.

[0024] Appendix Figure 3 As shown, a limiting ring 6 for holding the connecting plate 3 in place is provided in the rear opening of the housing 1. Press the connecting plate 3 into the rear opening of the housing 1 until the connecting plate 3 rests on the limiting ring 6, thus completing the installation of the housing 1 and the connecting plate 3.

[0025] The housing 1 is a cylindrical shell.

[0026] The center of the connecting plate 3 is provided with a mounting hole for connecting the moving mechanism.
