由泵和 snorkel 装置增强的浇水壶
Watering can augmented by pump and snorkel device
US-7325579-B2用于从容器抽水，通过泵启动虹吸，方便浇灌。
专利摘要
一种浇水壶包括泵和 snorkel，可用于将水从容器中抽出并进入浇水壶。snorkel 装置放入待排空水的容器中，泵动泵以启动水从容器流入浇水壶储水器的流动。在一些实施例中，泵为蠕动泵，其包括泵完全脱离的模式，流体可从 snorkel 自由流过泵并进入浇水壶储水器。这允许操作者使用泵启动虹吸过程，无需进一步泵送即可排空容器中剩余的水。当不用于从容器抽水时，浇水壶可常规方式使用。
Original abstractA watering can includes a pump and a snorkel which can be used to draw water out of a vessel and into the watering can. The snorkel device is put into a vessel from which water is to be evacuated and the pump is cranked in order to start the flow of water from the vessel and into the reservoir of the watering can. In some embodiments, the pump is a peristaltic pump which includes a mode where the pump is fully disengaged and fluid may flow freely from the snorkel, through the pump, and into the reservoir of the watering can. This allows the operator to use the pump to start a siphoning process which evacuates the remainder of the water from the vessel without further pumping. When not being used to draw water out of a vessel, the watering can may be used in the ordinary manner.
