[0045] The air outlet 130 is communicated with the fan 200, and the fan 200 sucks air in the water tank 100 through the air outlet 130 to make the inlet 110 have negative pressure, so that the mixed gas containing air and sewage can be sucked. The fan 200 and the drainage pump 300 are arranged outside the water tank 100 to facilitate maintenance.
[0046] The first filter assembly (not shown in the figure) is arranged in the water tank 100 and can be removed from the water tank 100. The first filter assembly has a water inlet for receiving sewage flowing out of the inlet 110, and the water inlet and the inlet 110 have a first interval for air outflow. The first filter assembly is used for sewage filtration. In some specific embodiments, the inlet 110 is located above the water inlet, and the mixed gas flows out of the inlet 110, and the sewage therein enters the first filter assembly under the action of gravity and inertia.
[0047] The fan 200 draws air out of the water tank 100 to create a negative pressure at the inlet 110, and thus to be able to draw the mixed gas. The mixed gas enters the water tank 100, in which the air flows out of the first space between the water inlet and the inlet 110, and is drawn out by the fan 200 to maintain the negative pressure at the inlet 110, and the sewage enters the first filter assembly through the water inlet, flows out after being filtered by the first filter assembly, and can be discharged out of the water tank 100 through the drain pump 300. The solid waste in the sewage is intercepted in the first filter assembly, and the first filter assembly can be detached and removed from the water tank 100, so as to take the solid waste out of the water tank 100 and achieve rapid cleaning of the solid waste.
[0048] Please refer to Figure 1 In some embodiments, the water tank 100 includes a tank body 161 and a tank door 162, and a first window is formed in the side wall of the tank body 161, and the tank door 162 is configured to be able to seal the first window or open the first window to remove the first filter assembly.
