[0011] like Figure 1 As shown, the utility model is an automatic wastewater discharge device for a cleaning machine, comprising a main tank body 1, a water tank 2 and a sewage tank 3. The main tank body 1 is located above the water tank 2, and the water tank 2 is located above the sewage tank 3. The main tank body 1 and the water tank 2 are both connected to a water inlet pipe 4. A first overflow port is provided on the main tank body 1, and a first overflow pipe 5 is connected between the first overflow port and the water tank 2. A filter bag 6 is provided in the water tank 2, and one end of the first overflow pipe 5 is connected to the filter bag 6. A pipe is also connected between the main tank body 1 and the water tank 2, and a first manual filter is provided on the pipe between the water tank 2 and the main tank body 1 in sequence along the flow direction. Valve 7, water pump 8 and filter 9, the main tank body 1 and the water storage tank 2 are each connected to the sewage tank 3 through a pipe, and a second manual valve 10 and an automatic valve 11 are respectively provided on the pipes between the main tank body 1 and the water storage tank 2 and the sewage tank 3. The water storage tank 2 is provided with a second overflow port, and the second overflow port is connected to the sewage tank 3 through a second overflow pipe 12. The sewage tank 3 is connected to the water inlet end of the sewage pump 13 through a pipe. A liquid level detection device is provided on the sewage tank 3. The automatic valve 11, the water pump 8, the control end of the sewage pump 13, and the signal output end of the liquid level detection device are all connected to a controller (not shown in the figure).

[0012] Furthermore, the liquid level detection device includes a vertical transparent tube 14 arranged outside the sewage tank 3. The transparent tube 14 is connected to the inner cavity of the sewage tank 3. A liquid level sensor 15 is arranged on the outer wall of the transparent tube 14.

[0013] Furthermore, the water inlet pipe 4 is connected to the main tank body 1 and the water storage tank 2 through a branch pipe 17 respectively, and a third manual valve 18 is respectively provided on each branch pipe 17.

[0014] Furthermore, the number of the main tank body 1 and the number of the water storage tank 2 are both two.

[0016] The working principle of this embodiment is as follows:

[0017] During operation, the outlet of the sewage pump 13 is connected to the sewage tank via a pipe. First, water is filled into the main tank 1 and water storage tank 2 through the water inlet pipe 4. The water pump 8 is then turned on, and workpieces are cleaned in the main tank 1. The overflowing water flows through the first overflow pipe 5 into the water storage tank 2. The waste residue from the cleaned workpieces is filtered through the filter bag 6 (residue collection bag). The water is then pumped back into the main tank 1 for recycling and filtered again through the filter 9. The water in the water storage tank 2 can overflow into the sewage tank 3 through the second overflow pipe 12. After a period of time, the automatic valve 11 opens, and the wastewater in the main tank 1 and water storage tank 2 is discharged into the sewage tank 3 through the automatic valve 11. The liquid level in the transparent tube 14 is synchronized with that in the sewage tank 3. When the liquid level sensor 15 detects that the liquid level in the transparent tube 14 has reached the corresponding level, the controller activates the sewage pump 13, discharging the wastewater into the sewage tank 16.

[0018] The utility model first discharges the waste liquid into the sewage tank 3 through the pipeline. After the sewage tank 3 reaches the corresponding liquid level, it is discharged into the sewage pool 16 for treatment through the sewage pump 13, realizing the automatic drainage function, thereby eliminating the need for manual transportation of the waste liquid tank, reducing manual labor intensity, and improving drainage efficiency.
