Abstract

An impeller and a water pump using same are disclosed. The impeller is mounted in a volute casing of the water pump and includes a base and a top cover, and a plurality of vanes provided therebetween. At least one of the top cover and the base is provided on an outer side surface thereof with a fluid-impeding flange to increase flow resistance in a cavity in the volute casing below the impeller, such that less fluid flows into the cavity below the impeller and the impeller in rotating would not be lifted by an upward force of buoyancy of the fluid, preventing the impeller top cover from impacting and rubbing against an inner side surface of the volute casing and largely reducing the frictional resistance and power consumption of the impeller. Therefore, the impeller produces less noise and enables upgraded operating efficiency, increased flow and prolonged service life.

Abstract

A quick coupler structure includes a male and a female coupler. The male coupler internally receives a fixed valve core surrounded by a spring and a connecting tube for connecting to a coupling platform at an upper part of the female coupler. The connecting tube is externally provided with sealing members to enhance airtight connection with the male coupler. The coupling platform defines a central thru-hole with a movable valve received therein to normally close it. When the fixed valve core is caused to expose from the connecting tube, it pushes the movable valve out of the central thru-hole to open the latter, allowing the male and the female coupler to communicate with each other. The sealing member won't be turned or loosened by a shearing force when the male and the female coupler are assembled or disassembled, giving the quick coupler structure upgraded air-tightness, pressure resistance and coupling reliability.
