The sealing protrusion ring 2b for the wire harness sealing quick connector is a concave structure. By designing the sealing protrusion ring 2b of the harness sealing quick connector as a concave structure, the ultrasonic flushing device is made more compact and easier to install.

[0066] The upper end of the sewer shell 2 is provided with a slag screen 2c. By integrating the slag screen 2c on the sewer shell 2, it is possible to prevent debris from leaking out of the gap between the upper end of the sewer shell 2 and the debris filter 12. The slag screen 2c protrudes upward, and a debris filter mounting ear 2d is provided on the outer edge of the slag screen 2c. By designing the slag screen 2c to protrude upward, the installation of the debris filter 12 is facilitated. Reinforcing ribs are provided on the inner wall of the slag screen 2c. The debris filter 12 is mounted on the slag screen 2c through the debris filter mounting ear 2d. The diameter of the upper end of the debris filter 12 is smaller than the diameter of the lower end. When the ultrasonic vibrator 1 is raised to the highest position, the top surface of the ultrasonic vibrator 1 is flush with the upper end of the debris filter 12. By design, when the sonic vibrator 1 is raised to the highest position, the top surface of the ultrasonic vibrator 1 is flush with the upper end of the debris filter 12 , thus preventing debris from leaking out of the gap between the debris filter 12 and the ultrasonic vibrator 1 .
