In the present embodiment, the housing 1 comprises a bottom wall 11 and a side wall 12, and the side wall 12 extends from the outer contour of the bottom wall 11 along the direction perpendicular to the bottom wall 11, so that the bottom wall 11 and the side wall 12 enclose the housing 1 with the inner cavity 3.

As shown in fig. 2 to 4, in the present embodiment, the dirt inlet 4 is disposed through the bottom wall 11, and the dirt inlet pipe 41 extending into the internal cavity 3 is fluidly connected to the dirt inlet 4. The end of the internal cavity 3, which is far away from the sewage inlet 4, of the sewage inlet pipe 41 is also provided with the gas-liquid separator 5, dirt is discharged from the sewage inlet pipe 41 along with air flow and then impacts the gas-liquid separator 5, and the gas-liquid separator 5 can efficiently separate the dirt (sewage) from gas. In the field of cleaning equipment, the gas-liquid separator 5 is a common device for gas-liquid separation in a sewage tank (i.e., a gas-liquid separation device), and the function and principle thereof are substantially the same, and the structure thereof varies according to actual requirements. In the present embodiment, a gas-liquid separator 5 is taken as an example in the drawings, the gas-liquid separator 5 is fixedly connected to the sewage inlet pipe 41, and the gas-liquid separator 5 has a liquid guiding portion and a gas guiding portion (not shown in the drawings).

The mounting member 21 and the conductor 22 are preferably provided in a columnar shape, so that the stability of mounting the conductor 22 can be improved.

The implementation principle of the embodiment is as follows: the user holds the handle 10 and moves the gas-liquid separating apparatus in a horizontal direction to mount it to the cleaning device. The second contact 81 of the conductive element 2 of the gas-liquid separation device is butted with the contact 91 of the cleaning device to realize electric connection, and the sewage inlet 4 and the exhaust port 6 at the bottom of the gas-liquid separation device are respectively connected with the corresponding fluid interfaces 92 on the cleaning device. When cleaning, the suction source of the cleaning equipment generates suction force, dirt enters the gas-liquid separation device from the dirt inlet 4 and the dirt inlet pipe 41, is separated by the gas-liquid separator 5, and is stored in the inner cavity 3 of the gas-liquid separation device, and airflow passes through the filter screen assembly 72 to reach the airflow chamber 71 on the sealing cover 7, then enters the exhaust pipe 61, and finally is discharged from the exhaust port 6. When the sewage level in the gas-liquid separation device reaches a certain height (namely, reaches the position of the first contact 8 of the conductive element 2), the first contacts 8 of the conductive elements 2 are electrically connected with each other by the sewage, so that the sewage level can be detected. After cleaning, the user holds the handle 10 to detach the gas-liquid separation device from the cleaning equipment, opens the sealing cover 7, and pours the sewage out of the top of the shell 1.
