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 tank body 10. The filter assembly 20 is fitted in the tank 10 and includes a main body 21 having an inlet end 2112 and an outlet end 2113, a first separating portion 22, and a first baffle 24, the main body 21 having a second space 213 formed therein communicating with the drain passage 12, the first baffle 24 being located in the second space 213 between the inlet end 2112 and the outlet end 2114. The first separating portion 22 is coupled to the main body 21 and communicates with the second space 213. Wherein the first baffle 24 cooperates with the body 21 to define a one-way flow path from the inlet end 2112 to the outlet end 2113. In this way, the sewage in the sewage pumping channel 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 channel, 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 pumping channel 12 enters the second space 213 under the driving of the airflow and flows through the one-way flow channel, the sewage will hit the first baffle 24, and due to the blocking of the first baffle 24, the sewage entering the second space 213 can all fall onto the first separating portion 22, so as to perform the separation of the solid matters and the non-solid matters in the sewage.

In one embodiment, the length of the flow path between the inlet end 2112 and the first baffle 24 is less than the length of the flow path between the first baffle 24 and the outlet end 2113. Wherein the length of the flow channel refers to the length of the actual flow path of the sewage, not the distance. That is, two original flow channels are arranged between the inlet end 2112 and the outlet end 2113, but the channel between the inlet end 2112 and the outlet end 2113 with the shorter length is provided with the first baffle 24 to block the sewage from flowing along the channel, and guide the sewage to flow unidirectionally along the channel between the inlet end 2112 and the outlet end 2113 with the longer length, 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 coupled to the box 10 and has an inlet 2112 and an outlet 2113. The second housing 212 is fitted over the first housing 211 and defines a second space 213 therebetween. The first separating portion 22 is a receiving groove formed on the second housing 212 and having an opening at one end, and the opening of the receiving groove is disposed facing the outlet end 2113. 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 2113 of the first housing 211 along the unidirectional flow path, and then falls into the storage tank of the first separation portion 22 opened facing the outlet end 2113, thereby performing separation of solid substances from non-solid substances.

Specifically, a 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 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 portion 2121 and the second housing 212; the third separation part 2122 has therein a third space 21221 in gas communication with the second space 213, and both sides of the third space 21221 in the extending direction thereof are in gas communication 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 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 the sewage flows through the one-way flow path in the second space 213, the gas can enter the housing 10 through the third space 21221 and continue to flow. Thereby forming a plurality of air flow passages between the second space 213 and the housing 10 to ensure the normal flow of the air flow and simultaneously realize the separation of solid and non-solid matters in the sewage.

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 separation portion 2122 also allow the liquid in the third space 21221 to pass therethrough, so that the liquid in the wastewater in the third space 21221 is leaked into the second space 213 to flow to the first separation portion 22 again. 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 a hollow cylinder, the hollow portion is a third space 21221, an axial direction of the third separating portion 2122 is perpendicular to a plane of the second separating portion 2121, and the third space 21221 extends along the axial direction of the third separating portion 2122.

In one embodiment, the filter assembly 20 further includes a fitting 23, and the body 21 is coupled to the fitting 23. The first housing 211 has a first mounting portion 2111, the first mounting portion 2111 faces the second separating portion 2121, and the first mounting portion 2111 forms a one-way flow passage extending in a spiral shape in the second space 213. Under the flow guidance of the spirally extending one-way flow passage, the sewage entering the second space 213 from the inlet end 2112 can rapidly flow to the outlet end 2113, thereby realizing solid-liquid separation.

Specifically, the first mounting portion 2111 has a first mounting hole 21111, the fitting 23 has a second mounting hole 231, one end of the third separating portion 2122 is connected to the second separating portion 2121, and the other end of the third separating portion 2122 is fitted into the second mounting hole 231 through the first mounting hole 21111, so that the first housing 211 and the second housing 212 are sequentially fitted to the fitting 23, and the entire filter assembly 20 is fixed in the housing 10 by connecting the inlet end 2112 to the drain passage 12.
