Title: SEAL STRUCTURE FOR WASTE LIQUID COLLECTING TANK
Abstract:
A seal structure for a waste liquid collecting tank. The seal structure comprises: a housing seat (2) disposed on a waste liquid collecting tank (1); a connecting rod mechanism (3) movably disposed on the housing seat (2); a sealing cover (4) connected to the connecting rod mechanism (3) and disposed on a waste liquid inlet (101) and on an air suction opening (102); and a top rod (5) connected to the connecting rod mechanism (3) and used for pushing and moving the connecting rod mechanism (3) to press the sealing cover (4) to seal the waste liquid inlet (101) and the air suction opening (102). A bottom end of the top rod (5) is connected to a side wheel component (6) of a floor washing machine and the top rod (5) can move up and down together with the side wheel component (6). The connecting rod mechanism (3) is respectively connected to the sealing cover (4) and to the top rod (5) connected to the side wheel component (6). The side wheel component (6) causes the top rod (5) to move up or down, simultaneously driving the connecting rod mechanism (3) to press down or lift up the sealing cover (4), thereby realizing the sealing or opening of the waste liquid inlet (101) and the air suction opening (102), and preventing leaking from the waste liquid inlet (101) of the waste liquid collecting tank (1) when the entire floor washing machine or the waste liquid collecting tank (1) is lifted. The invention improves user experience, protects internal components of a floor washing machine, and prolongs the life of the floor washing machine.
