[0008] The input end of the liquid extraction device is connected to the inside of the waste liquid collection box, and the output end of the liquid extraction device is connected to the inside of the waste liquid collection tank.

[0009] The liquid level sensing device includes a low liquid level suspended ball sensor, a medium liquid level suspended ball sensor, and a high liquid level suspended ball sensor.

[0010] Preferably, the liquid extraction device includes a pneumatic waste liquid lift pump, the input end of which is connected to the bottom end of the waste liquid collection box.

[0011] Preferably, the input end of the pneumatic waste liquid lifting pump is connected to a first filter.

[0045] This facilitates effective air filtration through the second filter 13.

[0046] In some specific embodiments, the input end of the pneumatic waste liquid lifting pump 8 is connected to the waste liquid collection tank 7 through the second manual valve 14, which facilitates the manual opening and closing of the waste liquid input through the second manual valve 14.
