In some embodiments, a partition rib 133 is provided on the annular inner wall 132, and the partition rib 133 includes a first windward surface 133a and a second windward surface 133b vertically arranged relative to the annular inner wall 132, so that the fluid flowing in the drainage shell 13 can flow along the first windward surface 133a and the second windward surface 133b toward the fluid outlet 11. At the same time, the noise caused by the impact of the two winds can be reduced, and the loss of wind pressure and wind speed can also be reduced.

[0066] The same and similar parts between the various embodiments in this specification can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0067] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
