The air inlet 250 of the air duct lower cover 230 is provided with a sealing ring between the openings of the box body 100, and a sealing gasket is arranged on the periphery of the opening outside the box body 100 so as to be in sealing connection with an air suction motor.

In order to ensure the structural strength of the box body, the box body is provided with a bending structure below the opening to form a reinforcing rib 140 of the box body, and referring to fig. 4, on the basis of the technical personnel in the field, in the scheme of the application, the box body can be provided with a plurality of the reinforcing ribs 140.

The suction motor draws out air inside the sewage tank through the air duct, so that negative pressure is formed in the sewage tank, and sewage is sucked into the sewage tank from the sewage suction port 110. The arrows in fig. 4 indicate the direction of gas flow within the air duct.

The air inlet 250 of the air duct upper cover 220 faces the lateral direction of the box 100, the buoy 300 is arranged in the box 100 corresponding to the air inlet 250, the buoy 300 falls to the designed height position under the action of natural gravity, as shown in fig. 4, and the top of the buoy 300 is flush with the lower end of the air inlet 250.

When the sewage in the sewage tank is about to reach the designed maximum safe water level, the water surface contacts the bottom surface of the buoy 300, and the buoy 300 rises simultaneously with the continuous rise of the water level.

When the buoy 300 ascends to the air suction opening 250 in the lateral direction of the air duct upper cover 220, the air suction opening 250 in the lateral direction of the air duct upper cover 220 is blocked by the buoy 300, the air quantity entering the air duct is reduced in a large amount instantly, the air suction motor detects the reduction of the air quantity and stops working, at the moment, the sewage in the sewage tank is full, the fan stops working, the sewage tank cannot continuously suck water, and the risk that the sewage enters the air duct system to cause the short circuit of the air suction motor by water due to the fact that the sewage is too full is avoided.

In the scheme of this application, the inside of box 100 be provided with soil pick-up mouth 110 intercommunication guide tube 400, the guide tube is used for controlling sewage and gets into the direction of box 100 makes the port that sewage got into from interior wind channel upper cover 220 the inlet scoop 250 distance is farthest away.

The guide pipe 400 can be detachably mounted at the sewage suction port 110 in the tank body 100 through a buckle, so that a user can conveniently detach the clean sewage tank, in the present application scheme, the sewage suction port 110 can be provided with the mounting joint 120, the mounting joint 120 is hermetically mounted at the sewage suction port 110 through a thread, the part of the mounting joint 120 is located inside the tank body 100, the part of the mounting joint 120 is located outside the tank body 100, the part of the mounting joint 120 located inside the tank body 100 is detachably connected with the guide pipe 400, and the part of the mounting joint 120 located outside the tank body 100 is provided with a sealing ring so as to be hermetically connected with the sewage suction pipe.

The clamping groove 410 is formed in the tail portion of the guide tube 400, the clamping groove 410 can be annular, a filter bag can be conveniently mounted on the guide tube 400, the annular clamping groove 410 can prevent the filter bag from falling off, and the filter bag can preliminarily filter large particles and solid garbage. Meanwhile, the filter bag can block the atomized sewage sucked by strong airflow, and the atomized water is gathered on the filter bag to form water drops to fall down, so that the excessive atomized water is prevented from being sucked into the air duct system of the main cover body 210.

In order to further prevent water flying out from the side surface of the filter bag from being directly sucked into the air duct system, a water baffle is arranged at the water inlet of the guide pipe 400 and fixed on the main cover body 210, when the main cover body 210 is covered, the water baffle just surrounds the guide pipe 400, if water flies out from the side surface of the filter bag, the flying water hits the water baffle, the water on the water baffle flows downwards under the action of gravity, and the water entering the guide pipe 400 is prevented from being transversely sucked into the air suction opening 250 of the air duct system.

In the scheme of this application, as shown in fig. 2 and 5, the baffle 500 includes a first blocking portion and a second blocking portion which are vertically disposed, the first blocking portion is located in front of the outlet of the guide tube 400, the second blocking portion is located at one side of the air suction opening 250, so that two sides of the extending direction of the guide tube 400 are respectively the inner wall of the box 100 and the second blocking portion, and the outlet of the guide tube 400 faces the first blocking portion.

In some embodiments, the filter bag may be flexible, and the filter bag may sag in its natural state. In order to prevent the sagging filter bag from clinging to the guide tube 400 and blocking larger solid garbage, the notch 420 is formed below the guide tube 400 close to the outlet, so that the sagging filter bag clings to the guide tube 400 and does not block the guide tube 400, and the incoming solid garbage can fall into the filter bag from the notch 420.

In this application scheme, the wind channel inlet scoop 250 moves towards the side direction of box 100, inlet scoop 250 is close to the top setting of box 100 can increase the box in not reducing the condition of safe water level under the distance of inlet scoop 250 and the surface of water reduces water and follows inlet scoop 250 gets into air duct system and then damages the risk of the motor that induced drafts.

In order to make the air suction opening 250 be higher, the air suction opening 250 may be formed by the air duct upper cover 220 and a cover body surrounding, the air duct upper cover 220 is arranged in a downward inclined manner at a position close to the air suction opening 250, and the air suction opening 250 is flared, referring to fig. 4.
