Referring to fig. 1 to 4, an embodiment of the present application provides a wastewater tank 100, which includes a tank body 10, a cyclone 20, and a first filter 30, wherein the tank body 10 has a wastewater pumping channel 12, the wastewater pumping channel 12 is in the tank body 10 and has a wastewater outlet 121, and the wastewater pumping channel 12 is used for pumping wastewater into the tank body 10 through the wastewater outlet 121. A cyclone impeller 20 is installed in the housing 10, and the cyclone impeller 20 serves to generate cyclone centrifugal force for the sewage flowing out of the sewage outlet 121 of the sewage suction passage 12. The first filter member 30 is fitted in the housing 10, and the first filter member 30 is located on a flow path of the contaminated water centrifuged by the cyclone impeller 20. In this way, the sewage of the sewage outlet 121 flows toward the first filter 30 by the cyclone impeller 20 to perform a separation operation of solid and non-solid matters in the sewage. Thereby realizing the separation of various substances with different forms in the sewage.

In particular, the sewage brought up by the airflow may include solids and liquids, or may include only solids. When sewage includes solid and liquid, then can realize solid, liquid and gas separation through cyclone impeller 20's whirlwind centrifugation, when not having liquid in the sewage, then can realize the separation of solid and gas through cyclone impeller 20's whirlwind centrifugation, avoided gas to carry solid or liquid rubbish to block up the air current passageway, also avoided containing the not good phenomenon of clearing up of solid in the liquid.

Understandably, the solid garbage with large volume is remained in the first filtering piece 30 after separation, and a user only needs to clean the first filtering piece 30 without independently contacting the garbage, so that the pollution of hands, clothes and the like can not be caused, the extra cleaning amount can not be increased, and the satisfaction and the experience of the user are greatly improved.

Thus, the sewage pumped out synchronously with the airflow in the sewage pumping channel 12 can be centrifugally beaten by the cyclone to the first filter 30 after contacting the impeller body 21. That is, it is ensured that the sewage pumped synchronously with the airflow in the sewage pumping channel 12 does not cross the impeller body 21, and the cyclone generated by the impeller body 21 is to prevent the sewage from ascending along with the airflow, thereby separating gas substances from non-gas substances. After the sewage is dropped by the impeller body 21, the sewage performs a separation operation of solid and non-solid matters on the first filter 30, so that further separation of the sewage is realized, and finally separation of gas matters, solid matters and liquid matters is realized.

Specifically, the impeller body 21 includes a plurality of circumferentially arranged blades, and generates a cyclone by 360-degree rotation of the blades.

In one embodiment, the impeller body 21 is eccentrically disposed with respect to the sewage outlet 121 toward a side close to the first filter member 30. So, when the rotatory whirlwind that produces of impeller body 21, form the low-pressure region in first filtration piece 30 side, form the high-pressure region in sewage export 121 side, take out the sewage that sewage passageway 12 was taken out and can be more easily under the effect of whirlwind from the high-pressure region flow direction low-pressure region to guarantee will take out the sewage centrifugation more easily in the sewage passageway 12 to first filtration piece 30 on, thereby guarantee the separation effect.

In one embodiment, the first filter member 30 has a mounting hole 31, and the drain water passage 12 is fixedly coupled to the first filter member 30 through the mounting hole 31. When the blades of the impeller body 21 start to rotate, wind generated by the cyclone can reach the sewage outlet 121 and the first filter member 30 at the same time, and blow the sewage onto the first filter member 30.

In one embodiment, the first filter 30 is a storage case with an opening, and the storage case body is provided with a plurality of first through holes 32 formed therethrough, and the opening is disposed toward the impeller body 21. The sewage dropped onto the first filter member 30, the solids are received in the storage case, and the liquid is leaked into the case 10 through the first through hole 32, thereby achieving the separation of the solids from the liquid.
