Description

Technical Field

[0001] The utility model relates to the technical field of fabric machines, and particularly to a waste water tank sealing structure for a fabric machine. Background Art

[0002] A fabric machine is a device for surface cleaning of textiles; currently, fabric machines on the market mainly include a housing, a water pump, an air pump, a steam generating device, a clean water tank, a waste water tank, a negative pressure fan, and a cleaning head; the water pump, the air pump, the steam generating device, and the negative pressure fan are all installed inside the housing, the clean water tank and the waste water tank are connected to the upper part of the housing, the steam generating device is connected to the water pump and the air pump, the water pump is connected to the clean water tank, the negative pressure fan is connected to the waste water tank, and the cleaning head is connected to the clean water tank and the waste water tank through pipelines. When the fabric machine is working, the water pump can pump the water in the clean water tank into the steam generating device, the air pump can transport compressed air into the steam generating device, the steam generating device can transport the steam through pipelines to the cleaning head, and the steam ejected from the cleaning head can clean the surface of the textiles. At the same time, when the negative pressure fan works, it can make the waste water tank generate negative pressure, and the steam or liquid water after cleaning the surface of the textiles can be sucked into the waste water tank. In addition, a waste water inlet and an air outlet are arranged at the bottom of the waste water tank; a first through hole and a second through hole are arranged on the housing below the waste water tank, and a first sealing ring and a second sealing ring are respectively embedded in the first through hole and the second through hole. The lower end of the first sealing ring is sleeved outside one end of the waste water channel in the housing assembly, and the upper end of the first sealing ring abuts against and circumferentially seals the outer bottom of the waste water tank on the circumferential outer side of the waste water inlet. The lower end of the second sealing ring is sleeved outside one end of the air extraction pipe in the housing assembly, and the upper end of the second sealing ring abuts against and circumferentially seals the outer bottom of the waste water tank on the circumferential outer side of the air outlet; however, in the existing fabric machine structure, the upper ends of the above-mentioned first sealing ring and the second sealing ring have the disadvantage of poor deformation ability, that is, there is a disadvantage that the tight sealing effect between the first sealing ring and the second sealing ring and the outer bottom of the waste water tank is poor. Therefore, when the negative pressure fan sucks air from the waste water tank through the air extraction pipe, air leakage is likely to occur, and when the waste water inlet of the waste water tank sucks the waste water in the waste water channel, water leakage is likely to occur. Summary of the Utility Model
