Description

Technical Field

[0001] The utility model relates to the technical field of drainage pump equipment, in particular to a drainage pump with a filtering function. Background Art

[0002] The washing machine drain pump drives the impeller to rotate through the motor, thereby generating negative pressure, sucking the sewage generated during the washing process into the pump body, and then discharging it from the washing machine through the drainage pipe. This process mainly includes three stages: water absorption, drainage, and stop. In the water absorption stage, the motor starts and drives the impeller to rotate, forming negative pressure to suck the sewage into the pump body; in the drainage stage, the sewage is discharged through the drainage pipe; in the stop stage, the motor stops working to prepare for the next washing cycle. When the traditional drain pump is used for drainage, when the water quality is turbid and there are too many debris in the water, it is very easy to suck the debris into the pump, resulting in insufficient drainage of the drain pump or failure to drain normally.

[0003] In the prior art, bolts are usually used to fix a set of filtering devices on the surface of the water inlet pipe, and the filtering devices are used to filter the debris in the sewage to avoid affecting the normal operation of the drainage pump.

[0004] However, the filter needs to be replaced and cleaned after being used for a period of time, but the filter device is fixed with bolts, which makes disassembly and installation more troublesome and even requires disassembly of the water inlet pipe. Utility Model Content
