[0049] First, the first water receiving area 31 is defined as an aqueous waste liquid collection area, and the second water receiving area 32 is defined as an organic waste liquid collection area. When performing extraction, first, according to the different types of waste liquid obtained by extraction, the automatic valve 6 connected to the corresponding area is controlled to open, and the waste liquid flows into the corresponding collection area along the drain pipe 5 connected to the water receiving tank 11. When the waste liquid in the collection area is collected to a certain liquid level height, the controller 8 controls the liquid level sensor 7 to alarm, reminding the user to drain the liquid to avoid waste liquid overflow.

[0050] In one embodiment, if Figure 1 and Figure 2 As shown, the fixing frame 2 includes: a connecting plate 22, a supporting column 23, a placing plate 24 and an adjusting plate 25.
