Abstract

The utility model discloses a waste discharge system which comprises a waste liquid collecting box, a pipeline structure, a waste liquid collecting box and two groups of clamping pieces, a waste liquid outlet is formed in the waste liquid collecting box, a waste liquid inlet is formed in the waste liquid collecting box, the two ends of the pipeline structure are inserted into the waste liquid outlet and the waste liquid inlet respectively and are connected with the waste liquid outlet and the waste liquid inlet in a sealed mode, and the two clamping pieces are installed on the waste liquid collecting box and the waste liquid collecting box respectively. And the two ends of the pipeline structure are respectively clamped and fixed. The waste discharge system does not need to pay attention to the position relation deliberately during installation, installation is convenient and fast, and the problems that the installation position is improper and reworking is needed do not exist; and the pipeline is fixed through the clamping piece, when replacement is needed, clamping is canceled, the pipeline is pulled out, and replacement and maintenance are easy.
