Referring to fig. 1 to 4, an embodiment of the present application provides a waste water tank 100, which includes a tank body 10 and a filter assembly 20, wherein the tank body 10 has a waste water pumping channel 12, and the waste water pumping channel 12 is used for pumping waste water into the waste water tank 100. The filter assembly 20 is assembled in the case 10, the filter assembly 20 includes a main body 21 and a spiral blade 22 rotating along the outer circumference of the main body 21 and extending along the axial direction of the main body 21, and the spiral blade 22, the main body 21 and the case 10 are together configured to form a separation flow passage. Wherein, the main part 21 peripheral lateral wall has a breach 211, draws sewage passageway 12 to pass through breach 211 and separation runner intercommunication, draws sewage in the sewage passageway 12 and gets into the separation runner through breach 211 under the air current drives to carry out the separation operation of solid matter and non-solid matter in the sewage along the rotatory while of separation runner. In this way, the sewage in the sewage pumping channel 12 is driven by the airflow to leave the sewage channel, and then enters the separation channel through the notch 211, and the separation of gas, solid and/or liquid is realized in the separation channel. The phenomenon that the airflow channel is blocked by solid and liquid garbage carried by gas is avoided, the phenomenon that the solid contained in the liquid is not easy to clean is also avoided, the separation of sewage in the sewage tank 100 is realized, and the user experience is improved.

In particular, the sewage brought up by the airflow may include solids and liquids, or may include only solids. When the sewage comprises solid and liquid, the solid, liquid and gas can be separated by the rotation of the sewage in the separation flow channel driven by the airflow. When no liquid exists in the sewage, the sewage is driven to rotate in the separation flow channel through the airflow, so that the separation of solid and gas can be realized, the blockage of the airflow channel caused by the solid carried by the gas or liquid garbage is avoided, and the phenomenon that the solid contained in the liquid is not easy to clean is also avoided.

In one embodiment, referring to fig. 3 and 4, one end of the spiral blade 22 is connected to the outer peripheral wall of the main body 21, and the other end extends toward the inner wall of the tank 10, and a certain distance is reserved between at least a part of the spiral blade 22 and the inner wall of the tank 10, and the distance allows the liquid in the sewage in the separation flow passage to pass through. Thus, when the sewage is carried by the airflow in the separation flow path, the liquid flows down from the gap due to its fluidity and gravity and is stored in the tank 10. However, since the solids in the raw sewage do not have fluidity, the solids are retained on the surfaces of the spiral blades 22 when flowing in the separation flow path along with the gas flow. And the airflow can leave the separation flow channel from various gaps or other reserved structures after finishing flowing in the separation flow channel, so that the separation operation of solid substances, gas substances and liquid substances in the sewage is realized.

Understandably, after separation, solid garbage remains on the surface of the helical blade 22 adhered in the separation flow channel, and a user only needs to clean the filtering component 20 without independently contacting the garbage, so that the pollution of hands, clothes and the like is avoided, extra cleaning amount is not increased, and the satisfaction degree and experience feeling of the user are greatly improved.

Specifically, due to the spiral arrangement of the spiral blades 22, the separation flow path of the sewage is lengthened, i.e. the separation flow channel has a certain length, thereby ensuring that various substances in the sewage can be separated sufficiently and effectively.

In one embodiment, the main body 21 has a ventilation chamber (not shown) communicating with the outside of the housing 10, the ventilation chamber is independent of the notch 211, and the main body 21 allows the gas in the separation flow passage to permeate and enter the ventilation chamber. The fact that the ventilation chamber and the gap 211 are independent means that the air flow and the sewage from the sewage suction channel 12 cannot directly enter the ventilation chamber through the gap 211, but need to flow through the separation channel to perform separation of gas, solid and/or liquid before sending the gas into the ventilation chamber.

Specifically, the air flow and the sewage from the sewage suction channel 12 enter the separation channel through the notch 211, and during the circulation in the separation channel, the main body 21 allows the air in the separation channel to permeate and enter the ventilation chamber, and the air flow can directly leave the sewage tank 100 from the ventilation chamber because the ventilation chamber is communicated with the outside of the tank body 10. Since the main body 21 does not allow solid and gaseous substances to pass therethrough, when the gas flow passes through the main body 21, the solid and liquid are beaten on the outer surface of the main body 21, thereby further separating the gaseous substances from the non-gaseous substances and continuing the solid-liquid separation operation in the separation flow path.

Specifically, referring to fig. 3 and 4, the main body 21 is provided with a plurality of through holes 214 leading to the ventilation cavity from the circumferential outer surface, and the through holes 214 only allow gas to pass through, so that the gas passes through the through holes 214 and enters the ventilation cavity through the main body 21.

In other embodiments, the main body 21 may also be some substances that can only ventilate in one direction (from the separation flow channel to the wind-dispelling cavity), so as to separate gas from solid and liquid, and is not limited to the solution of forming the through hole 214 in the above embodiments, and the present application is not limited thereto.

The sewage in the sewage pumping channel 12 enters the communicating cavity 213 under the driving of the airflow and then flows to impact on the blocking piece 24 to change the flow direction, and the airflow and the sewage with the changed flow direction enter the separation flow channel through the notch 211. After the separation operation is performed in the separation flow path, the gas enters the wind-dispersing chamber to be discharged to the outside of the foul water tank 100, the solids remain in the separation flow path to be adhered to the spiral vane 22, and the liquid flows down through the gap between the spiral vane 22 and the tank 10 to be stored in the tank 10.

Further, referring to fig. 2, the sewage suction channel 12 has an outlet 121 in the tank 10, the blocking member 24 is formed in an arc shape, and an arc concave surface of the blocking member 24 is disposed facing the outlet 121; wherein block that piece 24 is whole to cover export 121 towards the planar orthographic projection of export 121 place, so, guarantee that the sewage that export 121 flows can all hit on the circular arc concave surface that blocks piece 24 under the drive of air current to on flowing to helical blade 22 through breach 211 under the guide of circular arc surface, guarantee all sewage and all carry out the separation operation.

In one embodiment, referring to fig. 1, the foul water tank 100 further has a first space 11 and a pouring port 13 communicating with the first space 11, and the foul water pumping passage 12 is provided in the first space 11, and the liquid dropped into the tank 10 through the filter assembly 20 is stored in the first space 11. The filter assembly 20 is sleeved in the pouring opening 13, so that the air entering the ventilation cavity can be discharged out of the sewage tank 100 through the side of the pouring opening 13, and the complete flow of the air flow is completed. When it is desired to pour out the contaminated water in the first space 11, the filter assembly 20 is removed to open the pouring spout 13, and the contaminated water in the first space 11 is discharged through the pouring spout 13 by holding the contaminated water tank 100 to be inclined.
