Abstract: A water cleaner, including a housing, a filtering mechanism and a filtering unit. Two ends of the housing are respectively provided with an inlet and an outlet. The filtering mechanism is arranged in the housing. The sewage flows into the housing through the inlet and flows towards the filtering mechanism. The filtering mechanism is configured to filter the sewage to obtain clean water, which flows out of the housing through the outlet. The filtering unit is arranged at the inlet of the housing, and is configured to allow water remaining in the housing to be discharged and prevent dirt remaining in the housing from being discharged when the water cleaner stops sewage purification and is separated from the sewage.

Abstract: A water cleaner, including a housing and a filter mechanism. Two ends of the housing are provided with a first inlet and a first outlet, respectively. The filter mechanism is arranged in the housing. A first end and/or an outer circumstance of the filter mechanism are/is provided with a second inlet, and a second end is provided with a second outlet. The sewage flows into the housing through the first inlet and flows towards the filter mechanism to be filtered. The obtained clean water flows into the filter mechanism through the second inlet and flows out of the housing through the second outlet and the first outlet in sequence. The first end of the filter mechanism is close to the first inlet, and the second end is close to the first outlet.
