Wherein, the box body 10 is internally provided with a sealed sewage cavity 11, and the bottom surface 15 of the sewage cavity 11 is provided with a sink 12; the bottom surface 15 of the sewage cavity 11 is provided with a boss 13, the sinking groove 12 and the boss 13 are arranged at intervals, and the boss 13 is provided with a sewage drain hole 131.

The sealed sewage chamber 11 in the tank body 10 means that when the sewage tank 100 is not discharging sewage, the sewage in the sewage tank 100 will not flow out, that is, when the sewage tank 100 is in a natural state, the sewage in the sewage chamber 11 will not flow out.

Wherein, the bottom surface 15 of the sewage chamber 11 is provided with a sink 12, that is, the bottom surface 15 of the sewage tank 100 is partially recessed (the recess forms a sink), so that the bottom surface of the sink 12 is lower than the bottom surface outside the sink 12. When the tank body 10 is used for sewage discharge, sewage in the tank body 10 can be continuously collected towards the sink tank 12 under the action of self gravity, so that the sewage in the sewage tank 100 can be completely discharged.

Specifically, the case 10 includes a bottom panel, a side panel assembly 14, and a top cover 16. Wherein the bottom plate, the side plate assembly 14 and the top cover 16 enclose a sewage chamber 11. The inner side of the bottom plate (i.e. the side of the bottom plate facing the sewage chamber) forms the bottom surface 15.

Illustratively, the bottom plate is of a horizontal plate structure and comprises a vertical side, an arc-shaped side arranged opposite to the vertical side and 2 connecting sides. Each connecting edge connects the ends of the corresponding vertical edge and the arc edge. The vertical side, the arc side and the 2 connecting sides of the bottom plate are enclosed to form a letter D.

Illustratively, the sink 12 is disposed in the middle of the floor, the sink 12 being generally rectangular in configuration.

Illustratively, the boss 13 is located at the arcuate edge of the base plate and is disposed proximate to and midway between the arcuate edges. The orthographic projection of the boss 13 on the base plate is generally in the shape of an isosceles trapezoid. The boss 13 may be formed by protruding a part of the area of the bottom plate towards the direction of the sewage chamber 11, for example, the connection position of the second side plate 142 and the bottom surface 15, and the middle part of the area in the length direction of the second side plate 142 is concave to form the boss 13, accordingly, an avoidance groove is formed on one side of the bottom plate away from the sewage chamber 11, and the avoidance groove is used for avoiding a sewage suction pipe on a base station of a robot, so that the sewage suction pipe extends into the avoidance groove to be communicated with the sewage discharge hole 131, and sewage in the sewage chamber is discharged out of the sewage tank 100 through the sewage suction pipe. Specifically, the top surface of the boss 13 is a horizontal plane, and the drain hole 131 is arranged on the top surface, so that the structure is beneficial to sealing connection between the drain pipe 20 and the sewage suction pipe and the top surface, and is beneficial to avoiding water leakage of the sewage tank 100 in the process of draining sewage.

Illustratively, the end of the side panel assembly 14 adjacent the bottom panel is sealingly connected to the edge of the bottom panel. The side plate assembly 14 includes a first side plate 141 and a second side plate 142 disposed opposite to each other, and a connection plate 143 connecting the first side plate 141 and the second side plate 142. The first side plate 141 and the second side plate 142 extend along the length direction of the box 10, the first side plate 141 is a vertical plate, and the second side plate 142 is an arc plate. The first side plate 141 is disposed corresponding to a vertical edge of the bottom plate, the second side plate 142 is disposed corresponding to an arc edge of the bottom plate, and the connecting plate 143 is disposed corresponding to a connecting edge of the bottom plate. Of course, the side panel assembly 14 may also be considered as a side frame of the bottom panel extending toward a side perpendicular to the bottom panel.

Further, a guide inclined surface 17 is provided at the connection between the first side plate 141 and the second side plate 142 and the bottom surface 15, which is beneficial to the docking efficiency of the sewage tank 100 and the sweeping robot.

Illustratively, the top cover 16 is sealingly connected to an end of the side panel assembly 14 remote from the bottom panel. In particular, the top cover 16 is removably coupled to the side panel assembly 14 to facilitate manual cleaning of the waste chamber 11. The top cover 16 is a horizontal plate, and the shape of the top cover 16 is substantially the same as the shape of the floor, and will not be further described herein.

Further, referring to fig. 1, the top cover 16 is provided with a suction hole 161, and the suction hole 161 is communicated with the sewage chamber 11. The air suction hole 161 is used for being connected with a vacuum pump on the sweeping robot and is used for forming negative pressure in the sewage cavity 11 during operation so as to suck sewage in the sewage tank 18 into the sewage cavity 11 for storage, and the details are further described below.

In the present application, one end of the drain pipe 20 is disposed in the sink 12 so that the drain pipe 20 communicates with the sink 12, the other end of the drain pipe 20 is hermetically connected with the boss 13, and the drain pipe 20 communicates with the drain hole 131. It can be appreciated that in this embodiment, since one end of the drain pipe 20 is communicated with the sink 12, and the other end of the drain pipe 20 is communicated with the drain hole 131, when the sewage tank 100 stores sewage, the drain pipe 20 can isolate the drain hole 131 from sludge, so as to prevent the sludge from blocking the drain hole 131 when the sewage tank 100 stores sewage. Meanwhile, as the bottom surface 15 is provided with the sink groove 12, the sewage drain pipe 20 is communicated with the sink groove 12, and sewage in the sewage tank 100 can be continuously collected to the sink groove 12 in the sewage draining process of the sewage tank 100, so that the sewage in the sewage tank 100 can be completely discharged. Specifically, the drain 20 is generally letter "C" shaped, which is provided to further prevent sludge from clogging the drain hole 131 when the sewage tank 100 stores sewage.

Specifically, referring to fig. 2, the drain pipe 20 includes a mounting plate 21 at one end of the drain pipe, two ends of the mounting plate 21 span the sink 12, and two ends of the mounting plate 21 are fixedly connected with the bottom surfaces 15 at two sides of the sink 12, respectively. A mounting hole (not shown) is provided in the middle of the mounting plate 21, through which one end of the drain pipe 20 passes and extends into the sink 12.

In some embodiments of the application, the drain 20 may be a hose, such as a rubber tank or a flexible tube. Of course, in other embodiments of the present application, the drain pipe 20 may be a hard pipe, such as a polypropylene pipe, a polyethylene pipe, etc., without further limitation.

In some embodiments of the present application, a valve body (not shown) is provided in the drain pipe 20, and the valve body is used to open or close the drain pipe 20. Illustratively, the valve body may be a one-way valve. The valve body is in telecommunication connection with a control center of the sweeping robot. When the sweeping robot executes the sewage pumping instruction, the one-way valve is opened, so that the sewage cavity 11 is communicated with the sewage suction pipe on the base station of the robot. When the sweeping robot does not execute the dirt pumping instruction, the one-way valve is closed. This embodiment can further avoid outflow of sewage in the sewage chamber 11.

In some embodiments of the present application, referring to fig. 1 and 2, the sewage tank 100 further includes an ultrasonic vibrator 30, and the ultrasonic vibrator 30 is fixed to the tank 10. Specifically, the ultrasonic vibrator 30 is fixed to the first side plate 141 and is located in the sewage chamber 11. The start contact 31 of the ultrasonic vibrator 30 is located at a side of the first side plate 141 facing away from the soil chamber 11. When the sweeping robot returns to the robot base station to start to pump the sewage, the power supply of the robot base station is electrically connected with the starting contact 31, the robot base station supplies power to the ultrasonic vibrator 30, the ultrasonic vibrator 30 starts to work and vibrates sewage in the sewage tank 100, and the precipitated sludge is resuspended in the water. Then, the robot base station starts a sewage discharging procedure to pump away sewage in the tank body 10 of the sewage tank 100, thereby being beneficial to removing sludge in the sewage tank 100, and avoiding the drain hole from being blocked in the sewage discharging process. In the present application, the ultrasonic vibrator functions to provide mechanical vibration when energized, and to transmit the vibration to the sewage tank. The specific structure of the ultrasonic vibrator does not belong to the improvement point of the present application, and a person skilled in the art can select an appropriate ultrasonic vibrator according to the need, and the present application is not limited thereto.

In some embodiments of the present application, a sewage tank 18 is disposed on a side of the first side plate 141 facing away from the second side plate 142, a sewage pumping hole 1411 is disposed on the first side plate 141, and the sewage tank 18 is in communication with the sewage chamber 11 through the sewage pumping hole 1411. Specifically, the sewage tank 100 further includes a sewage suction pipe 40, and the sewage suction pipe 40 has a general letter "L". One end of the sewage suction pipe 40 is communicated with the sewage suction hole 1411, and the other end of the sewage suction pipe 40 extends towards the top direction (i.e. the direction of the top cover 16) of the box body 10, and the structure is beneficial to improving the capacity of the sewage chamber 11 for storing sewage. When the floor sweeping robot works, the vacuum pump enables the sewage cavity 11 to be in a negative pressure state through the air suction hole 161 by communicating the air suction hole 161 on the top cover 16 with the vacuum pump on the floor sweeping robot, so that sewage flowing into the sewage tank 18 is continuously sucked into the sewage cavity 11 for storage.

In some embodiments of the present application, the tank 10 and the sewage tank 18 are integrally formed, which is advantageous for improving the production efficiency of the sewage tank 100 and improving the overall strength of the sewage tank 100.
