摘要：A drainage system includes a water pump body, a water pump body water inletpipe, a water outlet pipe, a water storage apparatus and a connection fastener. Theconnection fastener is connected to the water inlet pipe and the water outlet pipe, thewater inlet pipe and the water outlet pipe are being joined embedded to form an annular

cavity. The inside of the annular cavity includes a filter, the periphery of the filter having alocating ring, the cross-section width of the locating ring is greater than the spacingbetween the front end surface of the connection fastener and a stop surface, and theconnection fastener includes a clamping apparatus. If a user forgets to mount the filter,the annular cavity between the water inlet pipe and the water outlet pipe makes theconnection between the water pump and the water storage apparatus unstable. If theuser tightens a thread structure to the position of the stop surface at this moment, theclamping apparatus and the water outlet pipe cannot be clamped yet since the cross-section width of the locating ring is greater than the spacing between the front endsurface of the connection fastener and the stop surface. The water pump is in an inclinedstate at this moment, prompting the user to mount the filter. An anti-toppling switch inthe water pump is off, and the water pump cannot work, thus ensuring the safety of theuser and the water pump.
