In the embodiment, referring to fig. 4 to 7, the waste water tank 100 includes a tank body 10 and a filtering assembly 20, the tank body 10 has a waste water pumping channel 12 communicated with an air suction pipe 322 for pumping waste water into the tank body 10; the filter assembly 20 is assembled in the case 10 and includes a main body 21 and a first separating portion 22, a second space 213 communicating with the sewage draining passage 12 is formed in the main body 21, and the first separating portion 22 is coupled to the main body 21 and communicates with the second space 213. The main body 21 includes an inlet 2112, an outlet 214 and a first baffle 2113, the first baffle 2113 is located in the second space 213 between the inlet 2112 and the outlet 214 for blocking the sewage at the inlet 2112 from flowing directly to the outlet 214, so as to form a one-way flow path between the inlet 2112 and the outlet 214 without passing through the first baffle 2113. In this way, the sewage in the sewage suction passage 12 enters the second space 213 under the driving of the airflow and flows to the first separating portion 22 through the one-way flow passage, so as to perform the separation of the solid matters and the 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 the separation of solid, liquid and gas through first separator 22, when not having liquid in the sewage, then can realize the separation of solid and gas through first separator 22, avoided the phenomenon that gas carried solid or liquid rubbish, also avoided the phenomenon that contains the solid and does not clear up well in the liquid.

Understandably, the solid garbage with large volume is remained in the first separating part 22 after separation, and a user only needs to clean the first separating part 22 without independently contacting the garbage, so that the pollution of hands, clothes and the like is avoided, the extra cleaning amount is not increased, and the satisfaction and the experience of the user are greatly improved.

In one embodiment, the first baffle 24 has one end attached to the body 21 between the inlet end 2112 and the outlet end 2113 and another end freely extending to block at least a portion of the inlet end 2112 and spaced from the inlet end 2112. For effectively blocking the inlet and outlet ends 2112 and 2113, thereby preventing communication between the inlet and outlet ends 2112 and 2113 through channels other than unidirectional flow channels.

In one embodiment, the first baffle 24 is disposed between the inlet end 2112 and the outlet end 2113, so as to prevent the sewage from flowing from the inlet end 2112 to the outlet end 2113, and prevent the sewage entering the second space 213 from the inlet end 2112 from flowing back to the inlet end 2112 after flowing to the outlet end 2113 through the one-way flow passage, thereby preventing the sewage from flowing back.

In one embodiment, when the sewage in the sewage suction channel 12 enters the second space 213 and flows through the one-way flow channel under the driving of the airflow, the sewage hits the first baffle 2113, and the sewage entering the second space 213 can fall onto the first separating portion 22 due to the blockage of the first baffle 2113, so as to separate solid matters from non-solid matters in the sewage.

In one embodiment, the length of the flow path for wastewater from the inlet end 2112 to flow along the unidirectional flow path to the outlet end 214 is greater than the length of the flow path for wastewater from the inlet end 2112 passing through the communication between the first baffle 2113 and the outlet end 214. Wherein the length of the flow channel refers to the length of the actual flow path of the sewage rather than the distance. That is, two original flow channels are arranged between the inlet end 2112 and the outlet end 214, but the first baffle 2113 is arranged on the channel with the shorter length of the flow channel between the inlet end 2112 and the outlet end 214 to block the sewage from flowing along the flow channel, and direct the sewage to flow unidirectionally along the channel with the longer length of the flow channel between the inlet end 2112 and the outlet end, so that the flow path of the sewage in the second space 213 is lengthened, and the flowing of the subsequent airflow is facilitated.

In one embodiment, the main body 21 includes a first housing 211 and a second housing 212; the first housing 211 is fitted in the case 10 and has a first baffle 2113 and an inlet end 2112 communicating with the second space 213. The second housing 212 is assembled to the first housing 211 with a second space 213 formed therebetween and an outlet end 214 communicating with the second space 213. The first separating portion 22 is coupled to the second housing 212 and disposed facing the outlet end 214. Along with the flow of the air flow, the sewage enters the second space 213 from the inlet end 2112 of the first housing 211, flows out from the outlet end 214 along the one-way flow path, and then falls onto the first separation portion 22 opened to face the outlet end 214 to perform separation of solid matter from non-solid matter.

Specifically, the closed second space 213 is formed by the first housing 211 and the second housing 212, so that the sewage reaches the first separation part 22 after entering the second space 213 to complete the separation of solid matters from non-solid matters, thereby facilitating the further cleaning after the separation.

In one embodiment, the second housing 212 includes a second separation portion 2121 and a third separation portion 2122, the second separation portion 2121 is coupled to the main body 21 and defines the second space 213 with the first housing 211, and the third separation portion 2122 is connected between the second separation portion 2121 and the first housing 211. And a second space 213 is formed between the second separation part 2121 and the second housing 212; the third separation part 2122 has therein a third space 21221 communicating with the second space 213 and into which only gas enters, and both sides of the third space 21221 in the extending direction thereof communicate with the inside of the casing 10. The second space 213 is in communication with the gas inside the cabinet 10 through the third space 21221. That is, the gas in the second space 213 can not only enter the housing 10 through the first separating portion 22, but also be flowed into the housing 10 through the third space 21221, thereby ensuring the suction force of the gas flow passage and preventing the gas flow from being affected by the filter assembly 20. Further, the first separating portion 22, the second separating portion 2121, and the third separating portion 2122 are each provided with a plurality of through holes a formed therethrough, and the through holes a allow only liquid and gas to pass therethrough. After the contaminated water in the second space 213 falls on the first separating portion 22, the liquid penetrates through the through hole a and falls into the case 10 due to gravity, and the gas can leave the filter assembly 20 from the through hole a of the first separating portion 22 and enter the case 10, so that the flow of the gas flow is continued. When the contaminated water flows in the one-way flow passage in the second space 213, the gas can sufficiently leave the filter assembly 20 from the through holes a of the second separating portion 2121 and enter the housing 10 because the path is long enough, and the flow of the gas flow is continued. When sewage flows in the one-way flow passage in the second space 213, gas can enter the tank 10 through the third space 21221 and continue to flow, so that a plurality of airflow channels are formed between the second space 213 and the tank 10, and solid and non-solid matters in the sewage are separated while ensuring normal flow of the airflow. In other embodiments, the first separation portion 22 may also be a flexible substance capable of permeating water and permeating air, so as to separate solid, liquid and gas, and is not limited to the solution of forming the through hole a in the above embodiments, and the application is not limited herein.

Further, in some extreme cases, such as water leakage and air leakage in the sewage suction passage 12, some sewage may enter the third space 21221. In order to overcome the above problem, the through-holes a formed in the third separating portion 2122 allow the liquid in the third space 21221 to pass therethrough, so that the liquid in the sewage in the third space 21221 is leaked into the second space 213 and then flows to the first separating portion 22. While the solid matter in the wastewater in the third space 21221 is not allowed to pass through, the solid matter is left in the third space 21221, and the liquid and the solid matter in the wastewater are further sufficiently separated.

Specifically, the third separating portion 2122 is hollow and cylindrical, the hollow portion is a third space 21221, and an axial direction of the third separating portion 2122 is perpendicular to a plane of the second separating portion 2121, so that a plurality of airflow passages are formed.
