Optionally, when the ear canal 120 is provided with a first locking protrusion, the pressure plate 310 may be provided with a second locking groove, and during installation, the first locking protrusion may be embedded in the second locking groove, Since the pressure plate 310 is fixedly installed on the target installation object 500 through the installation part 320, the pressure plate 310 presses on the ear canal 120, thereby pressing the water guide channel 110 on the target installation object 500, limiting the vertical displacement of the water guide channel 110, and at the same time The horizontal displacement of the water guiding channel 110 is restricted by cooperation between the first locking protrusion and the second locking groove.

Optionally, when the ear canal 120 is provided with a first locking groove, the pressure plate 310 may be provided with a second locking protrusion, and during installation, the second locking protrusion may be embedded in the first locking groove, Since the pressure plate 310 is fixedly installed on the target installation object 500 through the installation part 320, the pressure plate 310 presses on the ear canal 120, thereby pressing the water guide channel 110 on the target installation object 500, limiting the vertical displacement of the water guide channel 110, and at the same time The second locking protrusion cooperates with the first locking groove to limit the horizontal displacement of the water guiding channel 110 .

It should be noted that the above-mentioned vertical displacement and horizontal displacement of the water guide channel 110 are an example of an embodiment of the application, rather than a limitation of the application. For example, when the installation surface of the target installation object 500 is a horizontal surface, and the water guide channel 110 is installed on the installation surface, the direction perpendicular to the horizontal surface is the up-down direction, and the direction parallel to the horizontal surface is the horizontal direction. Similarly, when the installation surface is an inclined surface, the direction perpendicular to the inclined surface is the up-down direction, and the direction parallel to the inclined surface is the horizontal direction, which will not be repeated here.
