Abstract
The utility model discloses a liquid-collecting device capable of preventing leakage liquid from outflow and a water pump. The water pump mainly comprises a pump body and at least one liquid-collecting device, wherein the pump body is used for pumping liquid; the liquid-collecting device is mainly used for recycling leakage liquid for reutilization. Due to the abrasion of sealing components caused by long-time operation of the pump and inevitable leakage, a certain amount of liquid near to the sealing components always drips and remains on a casing body. The liquid remaining on the casing body is collected by liquid inlet pipelines, and is introduced into the cavity of the liquid-collecting device. When the liquid increases gradually, a switch valve is opened through the control of a liquid-level sensor switch, and negative pressure at the liquid input opening can suck the liquid back into the pump body. The passageway from a leakage opening to the liquid-collecting device and then to the pump, which the leakage liquid runs through, adopts a closed recirculation system, therefore, outward leakage of the leakage liquid can be prevented completely.
