The mysterious and peculiar ocean world includes many landscapes such as aquariums, beluga whale pavilions, shark pavilions, coral reef fish pavilions, and undersea sightseeing tunnels.

[0003] In an aquarium, there are a large number of marine organisms for people to watch. However, in order to allow more people to watch, the animals are usually kept in a transparent box to improve the viewing effect. However, due to the large size of the marine animals, a large amount of filth is likely to remain in the transparent box for raising the animals, so a sewage suction pump is needed for cleaning.

[0004] The suction end of the existing sewage suction pump is connected to a suction cylinder. When it is placed inside the box, it is easy to be blocked. And when cleaning, the relatively small-sized suction cylinder needs to be disassembled to clean it. Moreover, the existing cleaning equipment is inconvenient to install cleaning brushes with different diameters, resulting in incompatibility with suction cylinders of different diameters, so it is not convenient to use. Therefore, a sewage suction head for preventing a sewage suction pump from being blocked is proposed to solve the problems raised above. Content of the Utility Model
