At this time, the external waste liquid can be input into the liquid storage member 100 through the liquid path structure 330, and the liquid path structure 330 can be connected to the external liquid pipeline to avoid liquid leakage of the liquid path structure 330. At this time, since the filter 321 is arranged in the gas path structure 320 to filter the gas path channel of the cover body 310, the waste liquid can be prevented from polluting the environment by volatilization.

[0052] When the end cover assembly 300 is separated from the liquid storage member 100, the liquid path structure 330 is extracted from the sealing hole 211, and the sealing hole 211 of the sealing member 200 can be closed under the elastic action of the sealing member 200 to seal the inner cavity of the liquid storage member 100. Thus, the liquid storage member 100 can be sealed to avoid liquid leakage and gas leakage.

In addition, when the sealing flange 221 is made of a material with higher hardness than the sealing body 210, the strength of the connecting portion 220 can be improved to facilitate cooperation and fixation with the cover 310.

[0060] In an embodiment, the gas path structure 320 further includes a gas delivery pipe 322 connected to the filter 321 and the cover 310 respectively.

[0061] In the embodiment, since the filter 321 and the cover 310 are connected by the gas delivery pipe 322, the waste liquid collecting device 10 can install and fix the filter 321 at a predetermined position according to actual use requirements, and connect the gas path through the gas delivery pipe 322.
